Description

Technical Field

[0001] The utility model relates to the technical field of coal feeding equipment, and specifically, to an anti-jamming wheel type coal feeder. Background Art

[0002] Jigging separation is a process in which materials are separated by density during vertical lifting. A jig is a device for realizing jigging and is a commonly used separation device. Uniform feeding of the jig is a key factor for improving the separation efficiency of the jig.

[0003] At present, the coal feeders supporting jigs include vibrating coal feeders, reciprocating coal feeders, chain coal feeders, etc., but they cannot well ensure the continuous, stable and adjustable feeding amount of the jig, and there are also some limitations in the adaptability to materials. In addition, the internal structures of coal feeders are relatively complex. When dredging in case of blockage, it is necessary to avoid the internal feeding structure to prevent damage to components, which brings trouble to the maintenance work and reduces the work efficiency. In view of the above problems, the prior art has not solved them well, bringing trouble to the normal progress of work in this field. Therefore, there is an urgent need for an anti-jamming wheel type coal feeder to solve the above problems. Summary of the Utility Model

[0004] The utility model provides an anti-jamming wheel type coal feeder, which solves the problem that the internal feeding structure of the coal feeder in the related art occupies space and needs to be avoided during dredging in case of blockage, which is time-consuming and laborious.

[0005] The technical solution of the utility model is as follows: an anti-jamming wheel type coal feeder includes a housing, a rotating shaft, a pushing plate and a limiting part. The housing is provided with a feeding port and a discharging port. The rotating shaft is rotatably arranged in the housing. The end of the pushing plate is hinged to the rotating shaft. The limiting part is arranged on the rotating shaft and is located on one side of the pushing plate. Both the pushing plate and the limiting part are multiple. When the rotating shaft drives the multiple pushing plates to rotate towards the discharging direction, the pushing plate abuts against the limiting part, and the limiting part is used to provide the force for the pushing plate to push the material.

[0006] Optionally, it further includes a movable baffle. The end of the movable baffle is hinged to the housing. The movable baffle is located on one side of the pushing plate. After the multiple pushing plates rotate, they sequentially contact the movable baffle.

[0007] Optionally, it further includes an upper support plate. The upper support plate is arranged in the housing and is located on one side of the movable baffle. After the movable baffle swings, it abuts against or cancels abutting against the upper support plate, and the upper support plate is used to limit the angle of the movable baffle.

[0008] Optionally, it further includes a gate plate. The gate plate is slidably arranged in the housing. After the gate plate slides, it approaches or moves away from the pushing plate to change the feeding amount.

[0009] Optionally, there is an included angle between the gate plate and the vertical direction.

[0010] Optionally, it further includes a guide rail, a first motor, and a screw rod. The guide rail and the first motor are both arranged on the housing. The screw rod is rotatably arranged on the housing and is drivingly connected to the first motor. The gate plate slides on the guide rail, and the screw rod is threadedly connected to the gate plate.

[0011] Optionally, there is a maintenance opening on the housing. It further includes a maintenance door and bolts. The maintenance door is detachably arranged on the housing by means of the bolts and is used to close or open the maintenance opening.

[0012] Optionally, it further includes a second motor. The second motor is arranged outside the housing, and the rotating shaft is drivingly connected to the second motor.

[0013] Optionally, it further includes an electric control cabinet. The electric control cabinet is arranged outside the housing, and both the first motor and the second motor are electrically connected to the electric control cabinet.

[0014] Optionally, it further includes a lower support plate. The lower support plate is arranged inside the housing, at the lower right corner inside the housing, and below the upper support plate. There is an included angle between the lower support plate and the horizontal plane.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] A wheel-type coal feeding structure is designed, including a rotating shaft and a plurality of pushing plates, which are integrally in the shape of an impeller. There is a feeding port at the top of the housing for receiving coal material, and a discharging port at the bottom for connecting to a jig. A rotating shaft is rotatably arranged inside the housing. During operation, the rotation of the rotating shaft drives the synchronous rotation of the plurality of pushing plates, which can achieve uniform and stable feeding. Compared with traditional coal feeders, the overall structure is relatively simple.

[0017] Under normal working conditions, the plurality of pushing plates rotate counterclockwise. Under the abutting action of the limiting part, the pushing plates will stand up and push the coal material towards the discharging port. When a blockage occurs, if the pushing plates remain in an upright state, it will be troublesome to avoid the pushing plates carefully during dredging, which brings trouble to the dredging work. To solve this problem, the bottom end of the pushing plate is hinged on the circumferential surface of the rotating shaft, and a limiting part is arranged on the right side of each pushing plate. When feeding normally, the rotating shaft rotates counterclockwise, and the limiting part will abut against the pushing plate, restricting the swinging angle of the pushing plate and providing thrust for the pushing plate. When a blockage occurs, the pushing plates are clamped between the materials. At this time, in order to prevent the pushing plates from occupying space, the rotating shaft can be slowly rotated clockwise. When rotating clockwise, the pushing plates lose the abutting force of the limiting part and thus swing to the left. Eventually, the plurality of pushing plates will gather towards the center, thereby reducing their own occupied space and bringing convenience to the dredging and maintenance work.

[0026] Refer toFigures 1 to 2 This is the first embodiment of the present utility model, which proposes a wheel type coal feeder that prevents jamming, including a housing 1, a rotating shaft 2, a pushing plate 3, and a limiting part 4. The housing 1 is provided with a feeding port 5 and a discharging port 6. The rotating shaft 2 is rotatably arranged in the housing 1. The end of the pushing plate 3 is hinged to the rotating shaft 2. The limiting part 4 is arranged on the rotating shaft 2 and is located on one side of the pushing plate 3. Both the pushing plate 3 and the limiting part 4 are multiple. After the rotating shaft 2 drives the multiple pushing plates 3 to rotate in the discharging direction, the pushing plate 3 abuts against the limiting part 4, and the limiting part 4 is used to provide the force for the pushing plate 3 to push the material.

[0027] In this embodiment, a wheel type coal feeding structure is designed, including a rotating shaft 2 and multiple pushing plates 3, which is in the shape of an impeller as a whole. The top of the housing 1 is provided with a feeding port 5 for receiving coal material, and the bottom is provided with a discharging port 6 for connecting to a jig. A rotating shaft 2 is rotatably arranged in the housing 1. During operation, the rotation of the rotating shaft 2 drives the multiple pushing plates 3 to rotate synchronously, which can achieve uniform and stable feeding. Compared with traditional coal feeders, the overall structure is relatively simple.

[0028] Under normal working conditions, the multiple pushing plates 3 rotate counterclockwise. Under the abutting action of the limiting part 4, the pushing plates 3 will stand up and push the coal material towards the discharging port 6. When a blockage occurs, if the pushing plates 3 remain in an upright state, it is necessary to carefully avoid the pushing plates 3 during dredging, which brings trouble to the dredging work. To solve this problem, the bottom end of the pushing plate 3 is hinged to the circumferential surface of the rotating shaft 2, and a limiting part 4 is arranged on the right side of each pushing plate 3. When feeding normally, the rotating shaft 2 rotates counterclockwise, and the limiting part 4 will abut against the pushing plate 3 to limit the swinging angle of the pushing plate 3 and provide thrust for the pushing plate 3. When a blockage occurs, the pushing plates 3 are clamped between the materials. At this time, in order to prevent the pushing plates 3 from occupying space, the rotating shaft 2 can be slowly rotated clockwise. When rotating clockwise, the pushing plates 3 lose the abutting force of the limiting part 4 and swing to the left side. The multiple pushing plates 3 will eventually gather towards the center, thereby reducing their own floor space and bringing convenience to the dredging and maintenance work.

[0029] It further includes a movable baffle 7. The end of the movable baffle 7 is hinged to the housing 1. The movable baffle 7 is located on one side of the pushing plate 3. After the multiple pushing plates 3 rotate, they sequentially contact the movable baffle 7.

[0030] It further includes an upper support plate 8. The upper support plate 8 is arranged in the housing 1 and is located on one side of the movable baffle 7. After the movable baffle 7 swings, it abuts against or cancels the abutment against the upper support plate 8. The upper support plate 8 is used to limit the angle of the movable baffle 7.

[0031] In this embodiment, a movable baffle 7 is hinged at a position on the inner wall of the housing 1 near the feed inlet 5. An upper support plate 8 is arranged on the inner wall of the housing 1, and the upper support plate 8 is used to support the movable baffle 7 to keep the movable baffle 7 at a certain inclination angle. When the rotating shaft 2 drives the plurality of pushing plates 3 to rotate counterclockwise for pushing the material, the plurality of pushing plates 3 will sequentially contact the movable baffle 7, and the movable baffle 7 can guide the coal material between adjacent pushing plates 3, ensuring that the coal material is conveyed to the left side of the rotating shaft 2, avoiding the situation of reverse leakage of materials, and at the same time avoiding the sticking of the pushing plates 3 with materials.

[0032] It further includes a gate plate 9, the gate plate 9 is slidably arranged in the housing 1, and the gate plate 9 slides closer to or away from the pushing plate 3 after sliding, for changing the feeding amount.

[0033] An included angle is formed between the gate plate 9 and the vertical direction.

[0034] It further includes a guide rail 10, a first motor 11 and a screw 12. The guide rail 10 and the first motor 11 are both arranged on the housing 1, the screw 12 is rotatably arranged on the housing 1, the screw 12 is drivingly connected with the first motor 11, the gate plate 9 slides on the guide rail 10, and the screw 12 is threadedly connected with the gate plate 9.

[0035] In this embodiment, in order to realize the control of the feeding flow rate, a guide rail 10 is further arranged on the housing 1. The guide rail 10 penetrates through the side wall of the housing 1. A gate plate 9 is slidably arranged on the guide rail 10. The gate plate 9 is threadedly connected with the screw 12. The screw 12 can be driven by the first motor 11 to rotate, and the screw 12 drives the gate plate 9 to slide, thereby changing the distance between the gate plate 9 and the pushing plate 3. After the distance becomes larger, the feeding flow rate becomes larger. After the distance becomes smaller, the feeding flow rate becomes smaller. The feed inlet 5 is located at the top of the housing 1, so the coal material will fall vertically. In order to avoid the accumulation of the coal material on the gate plate 9, the gate plate 9 is designed to have an included angle with the vertical direction, and the gate plate 9 is inclined downward, so that the coal material can slide down by its own weight.

[0036] The housing 1 is provided with a maintenance opening 13, and it further includes a maintenance door 14 and bolts 15. The maintenance door 14 is detachably arranged on the housing 1 by means of the bolts 15, for closing or opening the maintenance opening 13.

[0037] In this embodiment, a maintenance opening 13 is further designed on the housing 1, and a maintenance door 14 is installed at the maintenance opening 13 by means of bolts 15. When a blockage occurs, first remove the bolts 15, and then open the maintenance door 14 to dredge or repair the blocked part, which is convenient for operation.

[0038] It further includes a second motor 16, the second motor 16 is arranged outside the housing 1, and the rotating shaft 2 is drivingly connected with the second motor 16.

[0039] It also includes an electric control cabinet 17, which is arranged outside the housing 1, and the motor 1 11 and the motor 2 16 are both connected to the electric control cabinet 17 circuit.

[0040] In this embodiment, in order to provide stable power to the rotating shaft 2, a motor 2 16 is arranged outside the housing 1, and the motor 2 16 is connected to the rotating shaft 2 to provide driving force for the rotation of the rotating shaft 2. In addition, an electric control cabinet 17 is also arranged outside the housing 1, and the motor 1 11 for controlling the gate plate 9 and the motor 2 16 for controlling the rotating shaft 2 are both connected to the electric control cabinet 17 circuit. A PLC monitoring system commonly used in the monitoring field is arranged in the electric control cabinet 17 to monitor the working current of the motor 2 16, so as to infer the working state of the rotating shaft 2, so as to judge whether a jam occurs. If it is monitored that the working current of the motor 2 16 is greater than the preset current, it is considered that a slight jam occurs at this time, and the torque of the rotating shaft 2 increases, then the gate plate 9 is driven away from the push plate 3 by the motor 11 to relieve the jam, and when the working current of the motor 2 16 returns to normal, the gate plate 9 returns to its original position. If the working current of the motor 16 is still too large after the gate 9 moves to the maximum position away from the push plate 3, the motor 16 slowly reverses to gather the push plate 3 toward the center to reduce the occupied space, and finally open the inspection door 14 for inspection.

[0041] It also includes a lower support plate 18, which is arranged in the shell 1, located in the lower right corner of the shell 1 and below the upper support plate 8, and there is an angle between the lower support plate 18 and the horizontal plane.

[0042] In this embodiment, a lower support plate 18 is provided at the lower right corner of the housing 1, and the lower support plate 18 is located below the upper support plate 8 and is inclined. The movable baffle 7 can block the coal from entering the right side of the rotating shaft 2 to avoid reverse leakage as much as possible. If a small amount of coal accidentally falls into the right side of the rotating shaft 2, the inclined lower support plate 18 can be used to guide the coal into the discharge port 6.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
