Description

An intelligent bucket-type lifting and unloading machine

Technical field

The present application relates to the technical field of grain lifting and unloading signal devices, and more specifically, to an intelligent bucket-type lifting and unloading machine.

Background technique

In order to facilitate the discharge of grain, the lower part of the side wall of the grain silo is generally equipped with a grain blocking door that can slide up and down. When the grain is shipped out of the warehouse, the grain blocking door is pushed upward, and the grain filled in the silo can pass through the outlet on the silo. The grain flows out of the silo. However, when too much grain accumulates in the silo, huge lateral pressure will be exerted on the grain blocking door. This pressure can easily cause the grain blocking door to deform or even get stuck, making it difficult to open the grain blocking operation. In order to improve the efficiency of grain delivery, workers need to use jacks to forcefully lift and open the grain retaining door located at the lower part of the grain silo. This can also easily cause the grain retaining door to be deformed and damaged, which will cause problems for the future entry of new grain into the silo and safe storage. Hidden danger.

In view of this, we propose an intelligent bucket-type lifting and unloading machine.

Beneficial effects: One or more of the technical solutions provided in the technical solution of this application have at least the following technical effects or advantages: 1. This lifting unloading machine facilitates the removal of excess grain from the silo when too much grain is accumulated in the grain silo. Lifting and transferring out of the silo prevents the silo grain blocking door from being squeezed by the grain in the silo and deforming or even getting stuck due to excessive accumulation of grain in the silo, which in turn makes it difficult to open the grain blocking door when the grain is shipped out. Appear.

2. Before injecting grain into the grain silo, insert one end of the hopper of the screw elevator into the interior of the grain silo, and then inject grain into the grain silo. The grain enters the interior of the screw elevator through the hopper of the screw elevator. It is then output from the output end of the screw elevator. During the process of lifting the grain in the transfer silo, the discharge port of the screw elevator can also be detected by the internal blockage sensing component provided on the screw elevator corresponding to the position of the screw elevator discharge port. Intelligent induction monitoring is carried out to determine whether the parts are blocked. When the outlet of the screw elevator is blocked, a fault warning signal can be actively sent to the staff to facilitate troubleshooting.

3. When the outlet of the screw elevator is blocked due to debris contained in the grain or due to grain agglomeration, the amount of grain entering the outlet is greater than the amount of grain discharged from the outlet, causing the outlet to fail. When there is a blockage, the amount of grain accumulated near the discharge port inside the screw elevator increases, which in turn generates pressure on the inner wall of the screw elevator. When the accumulated grain exerts pressure on the surface of the elastic sensing diaphragm in the internal blockage sensing component, the elastic sensing diaphragm is An elastic recess occurs in the end opening of the induction cylinder seat. When the pressure of the material on the inner wall of the spiral elevator is greater than the critical threshold, the air pressure in the dual-media working chamber is also greater than the preset critical value.

4. When the discharge port of the screw elevator is blocked and the elastic sensing diaphragm in the internal blockage sensing part is squeezed and broken by the grain gathered at the discharge port or punctured by sharp parts containing impurities in the grain, resulting in dual-media operation After the air pressure in the cavity is reduced, under the elastic tension of the stretched elastic tension band, the intermediate piston moving toward the elastic sensing diaphragm draws the insulating oil medium part of the annular cavity through the lead channel.

The staff can observe the reflection phenomenon. The paint surface layer infers that the elastic sensing diaphragm in the internal blockage sensing component has ruptured, so that the internal blocking sensing component can also perform real-time intelligent sensing monitoring of whether the elastic elastic sensing diaphragm has ruptured during operation, further facilitating work. The personnel troubleshoot the device and when the elastic sensing diaphragm ruptures, they can promptly disassemble and replace the internal blocking sensing parts to ensure the normal operation of the device.

And when the elastic sensing diaphragm 404 ruptures and the air pressure in the dual-medium working chamber decreases, the valve core structure can drive the secondary prompt structure to protrude from the inside of the annular chamber. One end of the lead channel is connected to the end of the dual-medium working chamber close to the fault signal light 401, and the other end is connected to the end of the annular cavity close to the fault signal light 401; one end of the air exhaust channel is connected to the end of the annular cavity close to the elastic sensing diaphragm 404 is connected, and the other end penetrates the side wall of the induction cylinder holder 402 and is connected with the atmosphere.

The front and rear sides of the screw elevator 1 are rotatably connected to a support frame 3; the front and rear sides of the screw elevator 1 are also rotatably connected to an electric push rod 2 for controlling the inclination angle of the screw elevator 1. Before injecting grain into the grain silo, insert one end of the hopper of the screw elevator 1 into the interior of the grain silo, and control the inclination angle of the screw elevator 1 by controlling the expansion and contraction of the electric push rod 2, thereby controlling the screw elevator 1 The purpose of extending the hopper into the interior depth of the silo is so that after the grain is injected into the grain silo, the device can extract grain at different depths in the silo as needed.

Referring to Figures 4 and 6, embodiments of the present application provide an intelligent bucket-type lifting and unloading machine. The valve core structure includes an intermediate piston 412 that is sealingly and slidingly connected to the interior of the dual-medium working chamber. The intermediate piston 412 is close to the elastic sensing film. One end of the piece 404 is connected to an elastic tension band 413, and the end of the elastic tension band 413 away from the intermediate piston 412 is connected to a fixed strip fixedly connected to the inside of the dual-medium working chamber; the end of the intermediate piston 412 away from the elastic tension band 413 is connected to The approach trigger terminal base 411 cooperates with the extended trigger terminal 410. The intermediate piston 412 is between the air medium part 406 and the insulating oil medium part 407 filled in the dual-medium working chamber. Before the elastic sensing diaphragm 404 ruptures, the air pressure of the air medium part 406 in the dual-medium working chamber is greater than the hydraulic pressure of the insulating oil medium part 407, and the elastic tension band 413 is in an elongated state. When the approach trigger terminal base 411 moves toward the end of the extended trigger terminal 410 and contacts the end of the extended trigger terminal 410, the fault signal light 401 is triggered and turned on. This lifting and unloading machine is convenient for lifting and transferring the excess grain out of the silo when there is too much grain accumulated in the silo, so as to avoid the silo grain blocking door being squeezed by the grain in the silo due to excessive grain accumulation in the silo. The pressure deforms or even gets stuck, which makes it difficult to open the grain door when the grain is shipped out of the warehouse. Before injecting grain into the grain silo, insert one end of the hopper of the screw elevator 1 into the interior of the grain silo, and then inject grain into the grain silo. The grain enters the interior of the screw elevator 1 through the hopper of the screw elevator 1 , and then output from the output end of the screw elevator 1. During the process of lifting the grain in the transfer silo, the screw can also be detected by the internal blockage sensing member provided on the screw elevator 1 corresponding to the position of the outlet of the screw elevator 1. Intelligent induction monitoring is carried out to determine whether the discharge port of elevator 1 is clogged. When the discharge port of screw elevator 1 is clogged, a fault warning signal can be actively sent to the staff to facilitate troubleshooting and transfer grain during the lift. During the process, when the outlet of the screw elevator 1 is blocked, it can be discovered immediately and the outlet of the spiral elevator 1 can be cleared in time to ensure the efficiency of the grain lifting and transfer work. When the discharge port of the screw elevator 1 is blocked due to debris contained in the grain or grain agglomeration, the amount of grain entering the interior of the discharge port is greater than the amount of grain discharged from the discharge port, causing the discharge port to be blocked. When the grain is gathered near the internal discharge port of the screw elevator 1, it increases, thereby exerting pressure on the inner wall of the screw elevator 1. When the accumulated grain exerts pressure on the surface of the elastic sensing diaphragm 404 in the internal blockage sensing member and makes the elasticity The sensing diaphragm 404 elastically recesses into the end opening of the sensing cylinder seat 402. When the pressure of the material on the inner wall of the spiral elevator 1 is greater than the critical threshold, the air pressure in the dual-medium working chamber is also greater than the preset critical value at this time, and then The air pressure in the dual-medium working chamber pushes the approach triggering end base 411 through the intermediary piston 412, and the approach triggering end base 411 contacts the approach triggering end base 411, triggering the fault signal light 401 to turn on, and the staff actively sends a fault warning signal to the staff through the illuminated fault signal light 401. , to facilitate staff troubleshooting.

Referring to Figures 4 and 5, embodiments of the present application provide an intelligent bucket-type lifting and unloading machine. The secondary prompt structure includes a piston ring body 405 that is sealingly and slidingly connected in the ring cavity. The piston ring body 405 is close to the fault signal light 401. An indented ring 403 is connected to one end of the indented ring 403, and the outer wall of the indented ring 403 is coated with a reflective paint layer 408. The end of the shrinking ring 403 away from the piston ring body 405 is sealed and passes through the end of the induction cylinder seat 402 . When the discharge port of the screw elevator 1 is blocked and the elastic sensing diaphragm 404 in the internal blockage sensing element is squeezed and broken by the grain gathered at the discharge port or punctured by sharp parts containing impurities in the grain, dual-media operation will occur. After the air pressure in the cavity is reduced, under the elastic tension of the stretched elastic tension band 413, the intermediate piston 412 moving toward the elastic sensing diaphragm 404 passes through the lead channel to remove the insulating oil medium in the annular cavity. Part 407 is drawn into the interior of the dual-medium working chamber. After the hydraulic pressure in the ring chamber gradually decreases, the piston ring body 405 drives the shrinking ring 403, which is coated with a reflective paint layer 408 on the surface, to protrude from the ring chamber. The staff can pass through the ring chamber. Observing the reflective paint layer 408 that reflects the phenomenon, it is inferred that the elastic sensing diaphragm 404 in the internal blockage sensing component has ruptured, so that the internal blocking sensing component can still detect whether the elastic elastic sensing diaphragm 404 has occurred during operation. The rupture is monitored by real-time intelligent induction, which further facilitates the staff to troubleshoot the device, and when the elastic sensing diaphragm 404 ruptures, the internal blocking sensing part can be disassembled and replaced in a timely manner.
