Description

Title:

Automatic Mechanical Buckets with Different Fixed Hook Position

Field of the invention:

The technical field of this invention is mechanical engineering and is related to transporting and unloading bulk cargo from the bulk material depot to the ship.

Review of the previous knowledge:

The loading and unloading of bulk materials, especially minerals, is traditionally done in the following ways:

1- Traditional bucket: The traditional bucket has the shape of a rectangular cube with an open top. To unload the bucket inside the ship's warehouse, the crane hooks are first removed by workers from the corners of the upper part of the bucket and locked to the earrings at the bottom of the bucket. After the bucket is lifted by the crane, the bucket is emptied. This method is very time consuming, in addition to having low safety. Also presence of work risks and pollution threatens workers inside the ship's warehouse.

2 - Grab (grab): Grab is similar to a large fork, having the ability to be closed in order to hold bulk materials and to move them. Using Grab in addition to expenses causes waste of material and leads to contamination. Also, using grabs provides the possibility of removal of bulk materials from the center of the ship's warehouse, and it is not possible to remove materials from the sides of the walls and corners.

3- Bellow: Bellow is used to load and unload bulk materials into the ships by using suction and snail systems. In addition to its high price, this system can only remove bulk grains.

A prominent problem still present in docks is the use of traditional buckets to load and unload cargos, having low safety and pollution that threaten workers inside the ship's warehouse. This invention is intended to eliminate the presence of workers inside the ship's warehouse and docks by making loading and unloading of bulk materials automatic.

The aim behind designing this device is to increase safety in docks, to reduce pollution and risks for personnel loading and unloading bulk materials, to reduce loading and unloading time and increase the volume of soft loading of mineral bulk materials such as iron ore, gypsum, sulfur, etc.

In designing and manufacturing this bucket, the rules of mechanics are implemented to significantly increase the volume of loading and unloading speed, as a result increasing the load.

This device includes the main parts below.

1- Main frame: The main frame is 370 cm wide and 220 cm and 170 cm high in the form of a rectangular cube (Figure 3). The body and the bottom door are designed so that no load remains inside the bucket at the time of unloading. The thickness of the steel used in the body should be above 6 mm so that the bucket has the necessary strength against load pressure.

2- Bucket door: Bucket door is made like a pyramid with a suitable slope so that there is no unloading time on it. The door 340 cm long and is coiled by cornering and studs (Figure 4) so that the door has the necessary strength against deformation. The door lock system properly connects the door to the body for providing maximum performance at the shortest time.

3- Open and closed drawers of the door: These drawers are connected to the body and door body by shafts and bushes and have the task of opening and closing the door properly and in the correct position.

4- Leverage: The lever can be made of rod or tube and when the door is closed and the bucket is raised, it keeps the door locked. And when the lever is discharged, it will be released automatically and while lifting the bucket, all the cargo will be discharged automatically.

Mechanism:

The mechanical automatic bucket is a rectangular cube, the lower part of which is on the two sides at an acute angle or in the form of a triangular door. This bucket is designed in the center part of the bucket and uses a fully automatic mechanical and automatic spring lever locking system. The lock will be locked when it sits on the bottom of the ship. It will be released due to the load pressure of the guarantor and discharges the load. The body and the bottom door are designed in a way that there will be no load left inside the bucket when unloading. The lever keeps the door locked when the door is closed then the bucket be lifted. The lever discharge mechanism will automatically function and the load will be discharged when the bucket is lifted.

Operational steps:

Step 1 : The toggle is open, firstly. Then the toggle will be connected by the worker by means of the toggle lock handle and with the help of spring pulling force (built-in sliding back shaft) and the interface breath rod, the toggle connects both sides of the bucket. During this operation, first the lock screen moves with the help of a sliding shaft with transverse motion on 2 levers that are welded to the body. Then, the door that is installed on the triangular door sits on the lock screen; this way the holder plate will be locked.

Step 2: When the envelope is raised at least 3 cm from the ground, the conical door that was installed on the triangular door moves downwards by about 2 cm when the door is lowered, pressing on the retaining plate and 2 lever brackets. It turns out that during this operation, the retaining plate is mechanically locked without the need for a worker and the lock handle of the guarantor, and prevents the lock and the guarantor from opening.

Step 3: When the bucket is placed on the ground again, the conical lid moves upwards and separates the retaining plate that was involved and locked. The 2 locking retaining plates were engaged by the interface rod, which was quickly pushed back and released, opening the lock.

Step 4: By opening the lever system lock and moving the bucket upwards, it opens the closed arms and connects to the triangular door. By opening the bucket door, all the cargo inside will be emptied. Load and unloading systems and locksmiths of this invention are only completely mechanical locksmiths. No hydraulic or electrical or pneumatic systems have been used, and this makes it possible for the workers to close the guarantor only once, so that the baggage lift will be locked by the toggle crane. The bucket will then be transported to the ship's warehouse, and after sitting on the floor of the ship's warehouse, the door opens automatically without the need for the presence of a worker.
