Description

Feed return mechanism of breeding equipment Technical Field

The invention belongs to the technical field of breeding equipment and relates to a material returning mechanism of breeding equipment.

Background Art

At present, biological treatment technology uses breeding equipment to breed insects. The insects on the breeding equipment will eventually grow into mature insects of appropriate size by ingesting and digesting food raw materials. The insects and insect excrement harvested from the breeding equipment can be further processed to obtain high-quality organic fertilizer.

The breeding equipment usually has multiple layers of conveyor belts, and the insects gradually grow up by passing through each layer of conveyor belts in turn. During the breeding process, each layer of conveyor belt usually stays for a period of time, such as 24 hours, for the insects to feed, and then transports them to the next layer of conveyor belt for further feeding. For example, a black soldier fly larvae breeding device disclosed in the patent document (application number: 202020173223.9) includes a discharging device and a multi-layer belt conveyor. Each layer of the belt conveyor is provided with a feeding end and a discharging end. The upper and lower belt conveyors are staggered along the length direction, so that the discharging end of the upper belt conveyor is above the feeding end of the lower belt conveyor.

The device has the following deficiencies in actual use: Since the development of insects is affected by many factors, including temperature, humidity, feed quality, density and breeding environment, in addition to the above factors, light, oxygen supply, etc. may also affect the development speed of insects. Therefore, in the actual production and manufacturing process of the device, it is inevitable that the insects will not mature when they reach the bottom conveyor belt. At this time, since the material on the bottom conveyor belt can only flow to the discharging device, the breeding equipment has the disadvantages of a relatively single and fixed conveying direction and insufficient operational flexibility. At this time, if the immature insects directly enter the discharging device for the manufacture of organic fertilizer, Since immature insects are usually smaller in size and have lower nutritional value, they cannot reach the production level of mature insects, resulting in problems such as reduced organic fertilizer production and insufficient nutrient content.

At present, in order to avoid the above problems, the conventional solution is to accurately control the temperature, humidity and other feeding conditions to ensure that the insects are mature when they reach the bottom conveyor belt. If the insects are still not mature when they reach the bottom conveyor belt, the time the insects stay on the bottom conveyor belt will be increased, and raw materials will be added to the bottom conveyor belt for the insects to eat again, until the insects are mature and then discharged to the discharging device.

Summary of the invention

The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a material return mechanism for aquaculture equipment. The present invention solves the problem that the existing aquaculture equipment has a relatively single and fixed conveying flow direction and low operating flexibility.

The object of the present invention can be achieved through the following technical solutions: a return mechanism for breeding equipment, the breeding equipment includes an upper conveyor belt, a lower conveyor belt and a discharging device, the end of the lower conveyor belt is located above the discharging device, and is characterized in that the return mechanism includes a conveyor belt assembly, an elevator and a horizontally arranged guide rail, the conveyor belt assembly is slidably connected to the guide rail, the conveyor belt assembly can be translated between the end of the lower conveyor belt and the discharging device and make the end of the conveyor belt assembly above the feed end of the elevator, and the discharging end of the elevator is located above the upper conveyor belt.

In this return mechanism, a horizontal guide rail is set and the conveyor belt assembly is slidably connected on the guide rail, so that the conveyor belt assembly can move horizontally. During the operation of the equipment, if the insects on the lower conveyor belt have grown to maturity, the end of the lower conveyor belt is located above the discharge device, so that the material output by the lower conveyor belt can directly fall onto the discharge device and then flow to the next processing station. If the insects on the lower conveyor belt are not yet mature, the conveyor belt assembly can be slid along the guide rail to between the end of the lower conveyor belt and the discharge device, and the end of the conveyor belt assembly can be located above the lifting station. The conveyor belt assembly is placed above the feed end of the machine, so that the material on the lower conveyor belt can pass through the conveyor belt assembly and the elevator in turn and return to the upper conveyor belt, and continue to be cultured on the upper conveyor belt for a period of time, such as 24 hours, while the lower conveyor belt can normally receive new insects for breeding and discharge. Of course, it can also wait for the insects on the upper conveyor belt to be raised and then enter the lower conveyor belt. Therefore, it has strong operation flexibility.

The return mechanism of the breeding equipment is achieved by adding a hoist and a conveyor belt component that can be moved on the basis of traditional breeding equipment. The conveyor belt component is cleverly designed to switch to different functional modes, so that the discharge position of the breeding equipment has two conveying directions of discharge and return. The conveying direction is no longer single and fixed. In this way, the conveying direction can be flexibly adjusted according to the development of insects on the lower conveyor belt, so that the breeding equipment has the characteristics of high operational flexibility, easy use, strong practicality, etc.

In the above-mentioned return mechanism of the breeding equipment, the conveyor belt assembly is arranged below the lower conveyor belt, and the guide rail and the conveyor belt assembly are arranged parallel to the lower conveyor belt. The conveyor belt assembly can extend outward from below the end of the lower conveyor belt. After the conveyor belt assembly extends outward, it is located between the end of the lower conveyor belt and the discharging device, and the end of the conveyor belt assembly is located above the feed end of the elevator.

In the initial reset state, the conveyor belt assembly is located below the lower conveyor belt, so that the conveyor belt assembly avoids the unloading space between the end of the lower conveyor belt and the discharge device, and thus does not block the material on the lower conveyor belt from falling onto the discharge device. When the conveyor belt assembly extends outward from below the end of the lower conveyor belt, the conveyor belt assembly is located between the end of the lower conveyor belt and the discharge device. At this time, the conveyor belt assembly switches to the docking return state, so that the material on the lower conveyor belt can pass through the conveyor belt assembly and the elevator in turn and return to the upper conveyor belt. In this design, the conveyor belt assembly is telescopically arranged below the lower conveyor belt. This structure effectively utilizes the space below the lower conveyor belt, and enables the conveyor belt assembly to quickly switch between the initial reset state and the docking return state by moving a small stroke, so that the equipment has the advantages of compact structure, high operating efficiency, and good stability.

In the above-mentioned return mechanism of the breeding equipment, the return mechanism also includes a mounting bracket, the lower conveyor belt is rotatably arranged on the mounting bracket, the guide rail is fixedly connected to the mounting bracket, and the conveyor belt assembly includes a docking bracket and a docking conveyor belt rotatably arranged on the docking bracket, and the docking bracket is slidably connected to the guide rail on the mounting bracket. The docking bracket is slidably connected to the guide rail on the mounting bracket, so that the conveyor belt assembly has high movement stability, thereby ensuring that it can switch positions stably and smoothly. The guide rail is arranged on the mounting bracket, so that the return mechanism does not need to additionally set up other components for installing the guide rail, thereby achieving the purpose of simplifying the structure. Moreover, this design allows the conveyor belt assembly and the lower conveyor belt to form a whole. When the placement position of the lower conveyor belt is changed again due to space requirements and other reasons, the relative position of the conveyor belt assembly and the lower conveyor belt does not need to be additionally adjusted, which makes the return mechanism have the advantages of easy use and strong practicality.

In the above-mentioned material return mechanism of the breeding equipment, the docking bracket includes two oppositely arranged side panels 1, the installation bracket includes two oppositely arranged side panels 2, the guide rails are two, the two guide rails are respectively fixedly connected to the outer walls of the two side panels 2, the upper ends of the two connecting plates are respectively slidably connected to the two guide rails through sliders, and the lower ends of the two connecting plates are respectively fixedly connected to the two side panels 1. The docking bracket is connected to the two guide rails through the two connecting plates, so that the left and right side panels 1 of the docking bracket are supported and positioned, thereby providing better stability and balance for the docking bracket, avoiding vibration and shaking caused by deflection or imbalance of the docking bracket, and improving the operating stability of the equipment. At the same time, the design can also evenly distribute the weight and load of the docking bracket to the two guide rails, reduce the load of the single-side guide rail, and thus increase the life and reliability of the guide rail.

In the above-mentioned feeding mechanism of the breeding equipment, the discharge end of the elevator is located above the head end of the upper conveyor belt, and a feeding component adjacent to the discharge end of the elevator is provided above the upper conveyor belt. The feeding component can be a feeding box with a discharge port at the bottom, or a feeding pipe, a feeding nozzle, etc. The feeding component is used to put nutrients. When the elevator brings immature insects to the upper conveyor belt, as the upper conveyor belt rotates, the immature insects are fed to the upper conveyor belt. When the upper conveyor belt rotates, the feeding parts also simultaneously put in nutrients, so that the upper conveyor belt can be evenly covered with insects and nutrients by the rotation of the upper conveyor belt, which is very convenient to operate. In the traditional multi-layer conveyor line, when the insects on the lower conveyor belt have not yet matured but the nutrients on the conveyor belt have been eaten by the insects, the lower conveyor belt cannot return the material and needs to be left still to wait for the insects to mature before being transported to the discharging device. Therefore, it is impossible to use the movement of the lower conveyor belt to feed the material, and the material can only be fed manually or by moving the feeding parts to cover the lower conveyor belt with nutrients, which will lead to problems such as troublesome feeding and high equipment costs.

In the material return mechanism of the above-mentioned breeding equipment, when the conveyor belt assembly extends outward from below the end of the lower conveyor belt, the end of the lower conveyor belt is located above the middle of the conveyor belt assembly, and a material baffle plate is also provided on the upper side of the head end of the conveyor belt assembly, and the lower edge of the material baffle plate is in contact with the upper surface of the connecting conveyor belt. The lower edge of the material baffle plate is in contact with the upper surface of the connecting conveyor belt, so that the material baffle plate has the function of preventing materials from falling. The end of the lower conveyor belt is located above the middle of the conveyor belt assembly, so that the conveyor belt assembly can better receive the materials dropped from the lower conveyor belt, and at the same time, with the action of the material baffle plate, it can better prevent the materials from falling from the head end of the conveyor belt assembly, ensuring that the materials dropped from the lower conveyor belt can be fully transported to the elevator through the conveyor belt assembly.

In the material return mechanism of the above-mentioned breeding equipment, the top edge of the side plate 1 is higher than the upper surface of the connecting conveyor belt, and the two side edges of the connecting conveyor belt are respectively in contact with the inner side walls of the two side plates 1. This design enables the side plate 1 to have the function of blocking materials, and can ensure that all materials dropped from the lower conveyor belt can be transported to the elevator through the conveyor belt assembly.

In the above-mentioned material return mechanism of the breeding equipment, the material return mechanism also includes a reinforcing plate and a horizontally arranged cylinder. The reinforcing plate is located at the lower side of the conveyor belt assembly. The two ends of the reinforcing plate are respectively fixedly connected to the lower ends of the two connecting plates. The cylinder bracket is provided with a horizontally arranged cylinder. The length direction of the piston rod of the cylinder is parallel to the length direction of the conveyor belt assembly, and the extended end of the cylinder piston rod is fixedly connected to the reinforcing plate. The two ends of the reinforcing plate are respectively fixedly connected to the lower ends of the two connecting plates, so that the two connecting plates and the reinforcing plate together form a relatively stable structure, thereby improving the installation of the conveyor belt assembly. Stability. Since the piston rod of the cylinder is fixedly connected to the reinforcing plate, the reinforcing plate also plays the role of connecting the cylinder, so that the cylinder can push the conveyor belt assembly to move back and forth. The piston rod of the cylinder can be kept in the state of extending outward or retracting inward, so that the conveyor belt assembly can be kept in the initial reset state and the connecting and returning state, making the equipment have the advantages of high degree of automation and stable operation.

In the above-mentioned material return mechanism of the breeding equipment, the material return mechanism also includes a locking pin arranged on the connecting plate, and a locking hole is opened on the second side plate. When the conveyor belt assembly extends outward to the position between the end of the lower conveyor belt and the discharging device, the locking pin can be inserted into the locking hole. This method is to manually operate the conveyor belt assembly to translate back and forth. When the return material needs to be connected, the conveyor belt assembly only needs to be manually pushed outward until the locking pin is aligned with the locking hole. At this time, the locking pin can be inserted into the locking hole, so that the conveyor belt assembly will not automatically retract inward, ensuring that the conveyor belt assembly can stably transport the material output by the lower conveyor belt to the elevator.

In the above-mentioned return mechanism of the breeding equipment, the discharging device is a horizontally arranged discharging conveyor belt, the length direction of the discharging device is perpendicular to the length direction of the conveyor belt assembly, and the elevator is arranged on the side of the discharging device facing away from the lower conveyor belt. This design can facilitate the arrangement of the discharging conveyor belt and the elevator, so that the elevator can be closer to the lower conveyor belt, which can shorten the length of the conveyor belt assembly and reduce the weight of the conveyor belt assembly. At the same time, the conveyor belt assembly only needs to move a small stroke to quickly switch between the initial reset state and the docking return state, so that the equipment has the advantages of compact structure, high operating efficiency, good stability, etc.

Compared with the prior art, the return mechanism of this breeding equipment has the following advantages:

1. The return mechanism of the breeding equipment adds a hoist and a movable conveyor belt assembly to the traditional breeding equipment. The conveyor belt assembly can be switched to different functional modes through an ingenious design, so that the discharge position of the breeding equipment has two conveying directions of discharge and return. The conveying direction is no longer single and fixed. In this way, the conveying direction can be flexibly adjusted according to the development of the insects on the lower conveyor belt, so that the breeding equipment has the characteristics of high operational flexibility, easy use, strong practicality, etc.

2. This return mechanism is provided with a feeding component adjacent to the discharge end of the elevator above the upper conveyor belt. When the elevator brings immature insects to the upper conveyor belt, the feeding component also simultaneously puts nutrients as the upper conveyor belt rotates. In this way, the insects and nutrients can be evenly spread on the upper conveyor belt by utilizing the rotation of the upper conveyor belt, which is very convenient to operate.

3. This material return mechanism also has the advantages of compact structure, high operating efficiency and good stability.
