Description

Technical Field

[0001] This application relates to the field of unloading equipment technology, specifically a rotary unloading device for stone and coal boxes. Background Technology

[0002] Coal slag, a type of industrial solid waste, is the residue discharged from coal-fired power plants, industrial and domestic boilers, and other equipment. It is also known as furnace slag. Its main components are silicon dioxide, alumina, iron oxide, calcium oxide, and magnesium oxide. Depending on its composition, it can be used to manufacture cement, bricks, and refractory materials. Some types can be used to produce alumina or to refine rare metals such as gallium and germanium.

[0003] When further processing slag and gravel, it is necessary to transfer and dispose of the scattered slag and gravel. Existing coal mills typically discharge slag and gravel in an open manner, resulting in large amounts of smoke and dust. To reduce smoke and dust, current technology often uses slag and gravel boxes to store the slag and locks them with locks using a special frame. Then, a forklift is used to lift the frame and pour the slag and gravel from the slag and gravel box into the processing equipment. However, most factories do not have dedicated forklift routes. Using forklifts to transfer slag and gravel poses certain safety hazards, and repeated transportation also wastes manpower.

[0004] Therefore, this application provides a rotary unloading device for a coal and stone box to solve the above problems. Utility Model Content

[0005] This application provides a rotary unloading device for stone and coal boxes, which aims to solve the problems of safety hazards and waste of manpower in existing forklift unloading as mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a rotary unloading device for a coal and stone box, comprising a base, a frame disposed on one side of the base for assembling the coal and stone box, a lock disposed on the frame for fixing the coal and stone box, an adjustment mechanism disposed on the base for lifting and tilting the frame, and a controller for controlling the operation of the adjustment mechanism. The adjustment mechanism includes two symmetrically distributed supports fixedly mounted on a base. Each support has a hinged support arm. A connecting part for supporting the frame is rotatably mounted on the end of each support arm away from the support. A first hydraulic cylinder for adjusting the angle of the support arm is hinged between the base and the support arm. A second hydraulic cylinder for adjusting the angle of the connecting part is hinged between the support arm and the connecting part. Both the first and second hydraulic cylinders are connected to the output end of a controller. In use, the base is placed on a horizontal surface on the feed side of the processing equipment. A coal box filled with stones is fed into the frame using a jack. The frame is then locked with a locking device to secure the coal box. The controller then controls the hydraulic station distribution valve to control the first hydraulic cylinder, pushing the support arm until it rotates 90° to a vertical position, thus raising the frame. The controller then controls the hydraulic station distribution valve to control the second hydraulic cylinder. The output end of the second hydraulic cylinder pushes the connecting part, rotating the coal box 90°, thereby raising the coal box. The stones and coal inside are poured into the processing equipment. The second hydraulic cylinder can be repeatedly extended and retracted, causing the frame to rotate repeatedly to empty the stones and coal from the box. The operation is convenient and reliable. Then, the second hydraulic cylinder is controlled to push the rotating unloading box back 90° to return to its original position. Then, the first hydraulic cylinder is operated to push the support arm back. Observe that the support arm has dropped to 90° and is in contact with the ground. Unlock the lock and use the pallet jack to pull out the stone and coal box. The equipment is fixedly placed without occupying too much passage space, saving costs. Moreover, the operator only needs to operate the controller equipment, which saves time and effort and ensures efficient operation.

[0007] Preferably, to facilitate frame rotation, the connecting part includes two symmetrically distributed connecting rods fixedly installed on the outer side wall of the frame. The end of the connecting rod away from the frame is rotatably connected to the end of the support arm away from the support, thereby completing the frame flipping action, which is convenient and quick.

[0008] Preferably, in order to reduce wear, a bearing is fixedly installed at the end of the support arm away from the support, and the end of the connecting rod is fixedly connected to the inner ring of the bearing, thereby reducing wear and improving the stability of the equipment.

[0009] Preferably, in order to improve stability, a number of reinforcing plates arranged in a circular array are fixedly installed on one end of the connecting rod near the frame. The reinforcing plates are fixedly connected to the outer wall of the frame to ensure the stability of the frame during long-term operation.

[0010] Preferably, in order to drive the support arm to lift, a first hinge block is fixedly installed on the base, and a second hinge block is fixedly installed on the outer wall of the support arm near the support. The body of the first hydraulic cylinder is hinged to the first hinge block, and the output end of the first hydraulic cylinder is hinged to the second hinge block, so as to ensure stable and efficient unloading.

[0011] Preferably, in order to rotate the frame, a third hinge block is fixedly installed on the inner side wall of the support arm, a crank is fixedly installed on the outer side wall of the connecting rod, the body of the second hydraulic cylinder is hinged to the third hinge block, and the output end of the second hydraulic cylinder is hinged to the crank, so as to empty the stones and coal in the stone and coal box, making the operation convenient and reliable.

[0012] This unloading device places its base on a horizontal surface on one side of the feed end of the processing equipment. A stone and coal box filled with stones and coal is fed into the frame via a jack. The frame is then locked in place by a locking device, securing the stone and coal box. The controller then controls the hydraulic station's distribution valve to control the first hydraulic cylinder, pushing the support arm until it rotates 90° to a vertical position, thus lifting the frame. Next, the controller controls the hydraulic station's distribution valve to control the second hydraulic cylinder. The output end of the second hydraulic cylinder pushes the connecting part, rotating the stone and coal box 90°, thereby emptying the stones and coal from the box into the processing equipment. The second hydraulic cylinder can be repeatedly extended and retracted, causing the frame to rotate repeatedly to empty the stone and coal from the box completely. The equipment is fixed in place, requiring minimal passageway space, saving costs. Furthermore, only the controller needs to be operated, saving time and labor, and ensuring efficient operation.

[0013] The unloading device connects the support arm and the connecting rod through a bearing, which makes the connecting rod rotate more smoothly and stably after being pushed by the second hydraulic cylinder, reducing wear and improving the stability of the equipment. Attached Figure Description

Figure 1-6 As shown, the unloading device includes a base 1, a frame 3 mounted on one side of the base 1 for assembling a stone and coal box 2, a lock 4 mounted on the frame 3 for fixing the stone and coal box 2, an adjustment mechanism 5 mounted on the base 1 for lifting and tilting the frame 3, and a controller 6 for controlling the operation of the adjustment mechanism 5. The adjustment mechanism 5 includes two symmetrically distributed supports 51 fixedly mounted on the base 1. Each support 51 is hinged with a support arm 52. The end of the support arm 52 away from the support 51 is rotatably mounted with a connecting part 53 for supporting the frame 3. A first hydraulic cylinder 54 for adjusting the angle of the support arm 52 is hinged between the base 1 and the support arm 52. A second hydraulic cylinder 55 for adjusting the angle of the connecting part 53 is hinged between the support arm 52 and the connecting part 53. Both the first hydraulic cylinder 54 and the second hydraulic cylinder 55 are connected to the output end of the controller 6.

[0018] In use, the base 1 is placed on a horizontal surface on one side of the feed end of the processing equipment. The stone and coal box 2, filled with stones and coal, is fed into the frame 3 using a ground jack. The frame 3 is then locked in place using the locking device 4, securing the stone and coal box 2. The controller 6 controls the hydraulic station distribution valve to control the first hydraulic cylinder 54, pushing the support arm 52 until it rotates 90° to a vertical position, thus lifting the frame 3. Then, the controller 6 controls the hydraulic station distribution valve to control the second hydraulic cylinder 55. The output end of the second hydraulic cylinder 55 pushes the connecting part 53, rotating the stone and coal box 2 by 90°, thereby lifting the stone and coal... The stones and coal in box 2 are poured into the processing equipment. The second hydraulic cylinder 55 can be repeatedly extended and retracted, causing the frame 3 to rotate repeatedly to empty the stones and coal in box 2. The operation is convenient and reliable. Then, the second hydraulic cylinder 55 is controlled to push the rotating unloading box back 90° to return to its original position. Then, the first hydraulic cylinder 54 is operated to push the support arm 52 back. Observe that the support arm 52 has dropped to 90° and is in contact with the ground. Open the lock 4 and use the pallet jack to pull out the stone and coal box 2. The equipment is fixedly placed without occupying too much passage space, saving costs. Moreover, the operator only needs to operate the controller 6, which saves time and effort and ensures efficient operation.

[0019] Specifically, the connecting part 53 includes two symmetrically distributed connecting rods 531 fixedly installed on the outer wall of the frame 3. The end of the connecting rod 531 away from the frame 3 is rotatably connected to the end of the support arm 52 away from the support 51.

[0020] In use, the frame 3 and the support arm 52 are connected by the connecting rod 531, so that the second hydraulic cylinder 55 can smoothly push the connecting rod 531 to rotate, thereby completing the flipping action of the frame 3, which is convenient and quick.

[0021] More specifically, a bearing 532 is fixedly installed on the end of the support arm 52 away from the support 51, and the end of the connecting rod 531 is fixedly connected to the inner ring of the bearing 532.

[0022] In use, the support arm 52 and the connecting rod 531 are connected by the bearing 532, so that the connecting rod 531 rotates more smoothly and stably after being pushed by the second hydraulic cylinder 55, reducing wear and improving the stability of the equipment.

[0023] Furthermore, a number of reinforcing plates 533 arranged in a ring array are fixedly installed on one end of the connecting rod 531 near the frame 3, and the reinforcing plates 533 are fixedly connected to the outer wall of the frame 3.

[0024] In use, the connecting rod 531 and the frame 3 are fixed by the reinforcing plate 533 to strengthen the support strength of the frame 3 and ensure the stability of the frame 3 during long-term operation.

[0025] Furthermore, a first hinge block 541 is fixedly installed on the base 1, and a second hinge block 542 is fixedly installed on the outer side wall of the support arm 52 near the support 51. The main body of the first hydraulic cylinder 54 is hinged to the first hinge block 541, and the output end of the first hydraulic cylinder 54 is hinged to the second hinge block 542.

[0026] In use, the controller 6 controls the hydraulic station distribution valve to control the first hydraulic cylinder 54, which pushes the support arm 52 until the support arm 52 rotates 90° to a vertical position, thus lifting the frame 3 so that the stone and coal box 2 can be unloaded in subsequent operations, ensuring stable and efficient unloading.

[0027] The support arm 52 has a third hinge block 551 fixedly installed on its inner side wall, and a crank 552 fixedly installed on its outer side wall. The body of the second hydraulic cylinder 55 is hinged to the third hinge block 551, and the output end of the second hydraulic cylinder 55 is hinged to the crank 552.

[0028] In use, after the frame 3 is lifted to a high position, the controller 6 controls the hydraulic station distribution valve to control the second hydraulic cylinder 55. The output end of the second hydraulic cylinder 55 pushes the crank 552, which drives the connecting rod 531 to rotate, causing the connecting rod 531 to rotate 90°, thus emptying the stones and coal in the stone and coal box 2 into the processing equipment. The second hydraulic cylinder 55 can be repeatedly extended and retracted, causing the frame 3 to rotate repeatedly, so that the stones and coal in the stone and coal box 2 can be emptied cleanly. The operation is convenient and reliable.
