Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor unloading technology, and in particular relates to a belt conveyor unloading bin unloading device. Background Technology

[0002] A belt conveyor is a conveying mechanism used to transport materials. During the material transport process, the material is first grabbed by a device such as a grab bucket and placed onto a discharge hopper installed at the feed end of the belt conveyor. After the material is discharged from the discharge hopper, it falls onto the belt conveyor and is then transported by the belt conveyor.

[0003] However, in actual operation, especially with belt conveyors operating in the open, materials such as sand are prone to clumping and solidification after being soaked by rainwater, and the sand also contains a large number of stones and slag. This causes the grab bucket to lower the material into the inclined hopper, where the material can easily get stuck. This is especially true when the material gets stuck at the discharge port of the discharge port, which is close to the belt conveyor, making it not only difficult to discharge the material but also very difficult to clean.

[0004] Therefore, in the existing technology, a grid is installed on the top of the unloading hopper. The grid is a mesh structure formed by welding multiple steel bars to separate lumps and large pieces of material in the sand.

[0005] However, in actual operation, because this type of fixed screen cannot clean itself, it becomes very difficult to clean once the screen openings are clogged with a large amount of clumps, stones, or debris. This is especially true for large unloading hoppers, which are very tall, making manual cleaning not only difficult but also extremely dangerous. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a conveyor belt unloading bin discharge device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A conveyor belt unloading bin feeding device includes an unloading bin, a feeding bin is detachably installed on the top of the unloading bin, a baffle mechanism is installed inside the feeding bin, and the baffle mechanism includes a plurality of fixed baffle rods respectively fixedly installed on opposite side walls of the feeding bin;

[0009] It also includes a flip-grid structure rotatably connected to the center of the feed hopper, the flip-grid structure comprising a plurality of flip-grid rods, the two ends of which extend into the gap between adjacent fixed grid rods;

[0010] The barrier mechanism also includes a flipping structure that drives the flipping structure to flip.

[0011] Preferably, the flip-gate structure further includes a central frame, and the fixed gate rods are distributed along the length of the central frame, with the fixed gate rods penetrating from the two side walls of the central frame.

[0012] Preferably, a drive shaft is fixedly connected inside the central frame, and the drive shaft passes through the center of the flip bar;

[0013] The two ends of the drive shaft are rotatably connected to the side wall of the feed hopper.

[0014] Preferably, the flipping structure includes a turntable fixedly installed on one side of the drive shaft, and also includes a hydraulic cylinder for pushing the turntable to rotate;

[0015] The turntable is fixedly connected to the eccentric position with a pin shaft, and the piston rod of the hydraulic cylinder is fixedly connected to a pin shaft sleeve hinged to the pin shaft.

[0016] The cylinder barrel of the hydraulic cylinder is hinged and mounted on the side wall of the unloading hopper.

[0017] Preferably, a material discharge mechanism is installed at the lower end of the unloading hopper;

[0018] The material feeding is assisted by a material feeding and unloading mechanism.

[0019] Preferably, the material discharge mechanism includes a rotating shaft rotatably connected to the lower end of the discharge bin, and a plurality of material discharge rods are welded and fixedly connected to the rotating shaft;

[0020] A drive structure for rotating the shaft is installed at the lower end of the outer side wall of the unloading hopper.

[0021] Preferably, the material-removing rods are distributed in several layers along the length of the rotating shaft, and each layer has several circumferentially arranged material-removing rods.

[0022] The material removal rods at adjacent layers are set symmetrically.

[0023] Preferably, the material feeding rod is L-shaped;

[0024] The drive structure includes a driven pulley fixedly installed at one end of the drive shaft, and a pulley motor. A driving pulley that drives the driven pulley via a transmission belt is fixedly installed on the output shaft of the pulley motor.

[0025] A motor bracket is fixedly installed at the bottom of the locking pulley motor, and the motor bracket is fixedly installed at the lower end of the side wall of the feed hopper.

[0026] Preferably, the feeding hopper is fixedly connected to a steel structure support frame.

[0027] Preferably, a plurality of toothed plates are welded to the top two sides of the flip bar.

[0028] This utility model has the following beneficial effects:

[0029] 1. During the unloading process, the grab bucket places the material into the feed hopper, while stone chips, stones, and clumps are blocked in the gaps between adjacent fixed grid bars; therefore, it also includes a flip-grid structure rotatably connected to the center of the feed hopper. The flip-grid structure forms a grid structure that separates the material and automatically clears obstacles blocking the gaps in the grid.

[0030] 2. When obstacles are stuck in the gap between adjacent fixed fence bars, the fence bars are flipped to raise them from the gap, dispersing stones, clumps of sand, and stone chips, thus reducing blockage.

[0031] Meanwhile, to further crush the material, several crushing plates are welded to both sides of the top of the aforementioned flip bar. The crushing plates are steel plates with an oblique triangular structure, which can moderately crush the material during the flip bar's movement of stones, lumps of sand, and stone chips. Simultaneously, with the subsequent grabbing and unloading of material by the grab head, the blocky material supported at the top of the crushing plates is further broken down by the impact of the material.

[0032] 3. The material discharge mechanism includes a rotating shaft rotatably connected to the lower end of the discharge bin (in existing systems, a suitable bearing is installed on the lower side wall of the discharge bin). Several L-shaped material-discharging rods are welded and fixedly connected to the rotating shaft. The material-discharging rods are distributed in several layers along the length of the rotating shaft, with each layer containing several circumferentially arranged material-discharging rods. Therefore, structurally, each layer of material-discharging rods welded to the rotating shaft forms a material-discharging unit. During rotation, the material-discharging rods continuously pull the material downwards, thus loosening tightly bound materials and simultaneously assisting in the downward discharge of the material.

[0043] Example 1

[0044] like Figure 1-5 As shown, a conveyor belt unloading bin feeding device includes an unloading bin 1, and a feeding bin 11 is detachably installed on the top of the unloading bin 1. The detachable nature allows for easy removal of the feeding bin 11 for subsequent cleaning, maintenance, etc.

[0045] The specific detachable method is as follows: the top opening of the unloading hopper 1 is welded with a lower mounting base 112 of a mouth-shaped structure, and the bottom opening of the corresponding feeding hopper 11 is welded with an upper mounting base 111 of a mouth-shaped structure. The upper and lower mounting bases 112 are detachably connected by bolts.

[0046] To prevent sand from clogging the discharge port of unloading bin 1 during the unloading process, especially sand that is wetted by rainwater or contains stones or slag, as well as clogging the transmission fixed baffle, which cannot be cleaned by itself, this utility model makes the following improvements:

[0047] A baffle mechanism 2 is installed inside the feed hopper 11. The baffle mechanism 2 includes several fixed baffle rods 21, which are respectively fixedly installed on opposite side walls of the feed hopper 11 (i.e., several fixed baffle rods 21 are respectively fixedly installed on the left and right side walls of the feed hopper 11, and a certain space is maintained between adjacent fixed baffle rods 21 to facilitate material passage. During the unloading process, the grab bucket puts the material into the feed hopper 11, while stone chips, stones, and lumps are blocked in the gaps between adjacent fixed baffle rods 21). Therefore, it also includes a flip-grid structure 22 rotatably connected to the center of the feed hopper 11. The flip-grid structure 22 forms a grid structure that blocks the material and automatically clears obstacles blocking the gaps in the grid.

[0048] Specifically, the flip-gate structure 22 includes several flip-gate rods 222 spaced apart front and rear, with both ends of the flip-gate rods 222 extending into the gaps between adjacent fixed gate rods 21. Since the flip-gate rods 222 can rotate, during actual operation, when obstacles become stuck in the gaps between adjacent fixed gate rods 21, the flip-gate rods 222 are flipped, raising them from their positions within the gaps and dispersing stones, clumps of sand, and stone chips, thus reducing blockage.

[0049] Meanwhile, to further crush the material, several crushing plates are welded to both sides of the top of the aforementioned flip bar 222. The crushing plates are steel plates with an oblique triangular structure, which can moderately crush the material during the flip bar 222's movement of stones, lumps of sand, and stone chips. Simultaneously, with the subsequent grabbing and unloading of material by the grab head, the blocky material supported at the top of the crushing plates is further broken down by the impact of the material.

[0050] If the fixed grid bar 21 on the left side is severely blocked during actual operation, the flip grid bar 222 can be raised on the left and lowered on the right, and vice versa, and the left and right sides can be raised alternately.

[0051] Example 2

[0052] like Figure 1-5As shown, based on the structure of Embodiment 1, the barrier mechanism 2 further includes a flipping structure that drives the flipping structure 22 to flip. The flipping structure 22 also includes a central frame 221 (shaped like a frame structure), and the fixed grid rods 21 are distributed along the length of the central frame 221. The fixed grid rods 21 penetrate through the side walls of the central frame 221 on both sides (during installation, holes are made in the side walls of the central frame 221, and the frame is welded and fixed after installation).

[0053] A drive shaft 23 is fixedly connected inside the central frame 221. The drive shaft 23 passes through the center of the flip bar (the center of the flip bar has a mounting hole. After the drive shaft 23 passes through, it is welded and fixed. The purpose of passing through all the flip bars is to increase the structural strength). The two ends of the drive shaft 23 are rotatably connected to the side wall of the feed bin 11 (according to the existing rotatable connection method, bearing holes for installing bearings are opened on the side wall of the feed bin 11, bearings are installed in the bearing holes, and the drive shaft is rotatably connected to the bearings).

[0054] During operation, some material is trapped at the central frame 221. As the flipping structure 22 flips, the material on the central frame 221 slides sideways and rolls down to a position close to the fixed grid bar 21. During this process, once the clumps hit the triangular structure breaking plate 34, the clumps, stone chips, etc. are further crushed under the impact force.

[0055] Therefore, in actual operation, the flip-gate structure 22 can be flipped multiple times to achieve auxiliary fragmentation and reduce the workload of manual cleaning.

[0056] The aforementioned tilting structure includes a turntable 24 fixedly installed on the rear side of the drive shaft, and a hydraulic cylinder 25 that drives the turntable 24 to rotate (the hydraulic cylinder 25 is a conventional hydraulic telescopic cylinder disclosed in the prior art, and its driving force is matched according to the model of the unloading bin. For example, for unloading bins with large models and large one-time material handling and unloading volume, a hydraulic cylinder with a larger driving force is matched); a pin is fixedly connected to the eccentric position of the turntable 24, and a pin sleeve hinged to the pin is fixedly connected to the piston rod of the hydraulic cylinder 25; the cylinder barrel of the hydraulic cylinder 25 is hingedly installed on the side wall of the unloading bin 1.

[0057] During operation, a hydraulic cylinder 25 is used to push the turntable 24. In the hinged state, the hydraulic cylinder 25 drives the turntable 24 to rotate during the pushing and pulling process, which in turn drives the rotating shaft to rotate. This method is used to drive the flip-gate structure 22 to rotate.

[0058] Example 3

[0059] like Figure 1-5As shown, this embodiment is based on the structure of embodiment 2. In actual operation, the amount of material fed into the large-volume unloading hopper 1 is very large. However, the sand and gravel that have been soaked in rainwater have poor fluidity. Therefore, once they are stuck at the discharge port at the bottom of the unloading hopper 1, it is very difficult to clean them manually.

[0060] Therefore, this utility model also includes a material discharge mechanism 3 installed at the lower end (discharge port position) of the unloading bin 1.

[0061] The material scooping and discharge mechanism 3 is used to loosen stuck materials by scooping them out, and at the same time, the material is discharged during the scooping action.

[0062] Specifically, the material discharge mechanism 3 includes a rotating shaft 33 rotatably connected to the lower end of the discharge bin 1 (in the conventional manner, a suitable bearing is installed on the lower side wall of the discharge bin 1). Several L-shaped material-discharging rods 34 are welded and fixedly connected to the rotating shaft 33. The material-discharging rods 34 are distributed in several layers along the length of the rotating shaft, with each layer containing several circumferentially arranged material-discharging rods 34. Therefore, structurally, each layer of material-discharging rods 34 welded to the rotating shaft forms a material-discharging unit. During rotation, the material-discharging rods 34 continuously pull the material downwards, thus loosening tightly stuck materials and simultaneously assisting in the downward discharging of the material.

[0063] The material removal rods 34 at the adjacent layers are arranged symmetrically, that is, the material removal rods 34 of the adjacent layers are arranged facing each other, in order to improve the removal effect.

[0064] A drive structure for rotating the drive shaft 33 is installed at the lower end of the outer side wall of the unloading bin 1. Specifically, according to the existing pulley drive structure, the drive structure includes a driven pulley fixedly installed at one end of the drive shaft, and a pulley motor 32. A driving pulley 31 that drives the driven pulley via a transmission belt is fixedly installed on the output shaft of the pulley motor 32. A motor bracket is fixedly installed at the bottom of the locking pulley motor 32, and the motor bracket is fixedly installed at the lower end of the side wall of the feeding bin 11.

[0065] During operation, driven by the pulley motor 32, the shaft rotates, which in turn rotates the material-discharging rod 34. The stuck and compacted material is loosened and discharged under the continuous discharging action of the material-discharging rod 34. Once the material is discharged, the chain can smoothly discharge the material.

[0066] Example 4

[0067] like Figure 1-5 As shown, this embodiment is based on the structure of embodiment 3 and is the same as the existing unloading hopper 1. The feeding hopper 11 is fixedly connected to a steel structure support frame to support the unloading hopper 1.

[0068] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
