Description

Technical Field

[0001] The utility model relates to the technical field of material transmission and guiding, in particular to a double-layer sealed material guiding trough device. Background Art

[0002] The material guide chute is a key component of bulk material conveying equipment, guiding the material along the belt for stable transport. Existing material guide chutes experience wear and tear in the sealing rubber over extended periods of operation, increasing the gap between the rubber and the belt. If the material being conveyed in the chute is powder, dust can easily escape during transport. Existing material guide chutes are typically designed for granular materials and are ineffective for conveying powders, which are prone to dust leakage.

[0003] The utility model with publication number CN210126874U proposes a material guiding device, which is applied to the field of material guiding technology, and includes: a material guiding trough support structure, which is connected to the material guiding trough structure and fixes the material guiding trough structure; a material transport structure, which is placed at the bottom of the material guiding trough structure and transports the unloaded material of the material guiding trough structure; the material guiding trough structure includes: a first side sealing rubber is arranged on the inner side of the bottom of the material guiding trough and is fixed by a first fastening device, and a second side sealing rubber is arranged on the outer inner side of the bottom of the material guiding trough and is fixed by a second fastening device; the bottom end of the material guiding trough is higher than the bottom ends of the first side sealing rubber and the second side sealing rubber, and the bottom ends of the first side sealing rubber and the second side sealing rubber are both in contact with the material transport structure, and a wear-resistant lining is fixed on the outer side of the first side sealing rubber. When applying the embodiment of the utility model, an additional sealing rubber is added to the inside of the material guiding trough to achieve a double-layer seal, thereby achieving a more stringent sealing effect of the material guiding trough.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. There must be a gap between the first side sealing rubber, the second side sealing rubber and the conveyor belt. This gap is a channel for dust leakage, that is, the prior art has the deficiency of poor sealing; 2. When the guide trough is guiding the material onto the conveyor belt, the material and the conveyor belt will not only impact the inner wall of the guide trough left and right when they come into contact, but also impact the gap between the guide trough and the conveyor belt front and back. That is, the dust will overflow along the front and back direction of the conveyor belt, and this part of the dust is difficult to eliminate.

[0005] To this end, the utility model provides a double-layer sealed material guide chute device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a double-layer sealed material guide trough device to solve the problems raised in the above background technology. The utility model has the function of eliminating the gap between the left and right side walls of the material guide trough body and the conveyor belt, thereby improving the double sealing effect. It also has the function of negative pressure dust removal before and after the material guide trough, thereby greatly improving the environmental protection performance of the device.

[0007] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a double-layer sealed material guide trough device, including a material guide trough body located above the conveyor belt, inner sealing rubber plates are fixedly provided at positions near the bottom on both sides of the material guide trough body, and a row of inner soft rubber sheets distributed along the length direction are provided at the bottom of the inner sealing rubber plates, outer sealing rubber plates are fixedly provided at positions near the bottom on both sides of the material guide trough body, and a row of outer soft rubber sheets distributed along the length direction are provided at the bottom of the outer sealing rubber plates, and the bottoms of the front and rear sides of the material guide trough body are provided with clearance gaps, and the front and rear sides of the material guide trough body are fixedly connected with dust collecting covers opposite to the clearance gaps, and one side of the inner soft rubber sheet and the outer soft rubber sheet are both against the upper end face of the conveyor belt.

[0008] Furthermore, connection holes are provided on both sides of the material guide trough body, and the inner sealing rubber plate and the outer sealing rubber plate are connected to the left and right side walls of the material guide trough body through the cooperation of bolts and the connection holes.

[0009] Furthermore, the spacing between the inner soft films in a row is zero, and the spacing between the outer soft films in a row is also zero.

[0010] Furthermore, the cross section of the dust collecting hood is an arc-shaped structure with the inner arc surface facing downward, and an air collecting box is fixedly provided on the top of the dust collecting hood, and an exhaust pipe is provided on the top of the air collecting box.

[0011] Furthermore, the clearance gap is a circular arc surface structure with the inner arc surface facing the conveyor belt. The inner arc surface of the clearance gap is fixedly connected with densely distributed cloth strips, and the bottom of the cloth strips extends to the upper end surface of the conveyor belt.

[0012] Furthermore, evenly distributed cloth ropes are hung on the left and right sides of the dust collecting hood, and the bottoms of the cloth ropes extend to the upper end surface of the conveyor belt.

[0013] Furthermore, the width of the inner soft film and the outer soft film is at least 50 mm.

[0014] The beneficial effects of the utility model are as follows:

[0015] In the present invention, a row of outer soft rubber sheets and a row of inner soft rubber sheets are provided at the bottom of the outer sealing rubber sheet and the inner sealing rubber sheet. When in use, one side of the row of outer soft rubber sheets and the row of inner soft rubber sheets are elastically squeezed onto the conveyor belt. When the conveyor belt is running, the gap between the conveyor belt and the outer sealing rubber sheet and the inner sealing rubber sheet is eliminated by the stacked and squeezed row of outer soft rubber sheets and the row of inner soft rubber sheets, thereby greatly improving the double sealing effect on both sides of the material guide trough device.

[0016] In the present invention, dust collecting hoods are arranged at the front and rear ends of the material guide trough body, and the dust collecting hoods are located above the conveyor belt. When the conveyor belt is running, the material descending in the material guide trough body will overflow in the upstream and downstream directions. At this time, the dust collecting hoods will collect the overflowed dust, which greatly improves the environmental protection performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a double-layer sealed material guide trough device, including a material guide trough body 2 located above the conveyor belt 1. The material guide trough body 2 can be a square box structure. When in use, the outer wall of the material guide trough body 2 is installed on the external support frame through a positioning plate. The top of the material guide trough body 2 will fall onto the conveyor belt 1 after unloading, and the conveyor belt 1 will operate to transport the material on it to the destination.

[0024] In this technical solution, inner sealing rubber sheets 3 are fixedly installed near the bottom on both sides of the guide trough body 2. There is a gap between the inner sealing rubber sheet 3 and the upper end face of the conveyor belt 1. A row of inner soft rubber sheets 31 distributed along the length direction is provided at the bottom of the inner sealing rubber sheet 3. The inner soft rubber sheets 31 serve to fill the above-mentioned gap. When the conveyor belt 1 is running, it will drive a row of inner soft rubber sheets 31 to be stacked and tilted. One side of the tilted inner soft rubber sheet 31 will be against the upper end face of the conveyor belt 1. The stacked and tilted row of inner soft rubber sheets 31 can eliminate the gap between the inner sealing rubber sheet 3 and the conveyor belt 1, and this arrangement can reduce the friction between the inner soft rubber sheet 31 and the conveyor belt 1. Outer sealing rubber sheets 4 are fixedly installed near the bottom on both sides of the guide trough body 2. A row of outer soft rubber sheets 41 distributed along the length direction is provided at the bottom of the outer sealing rubber sheet 4. The outer soft rubber sheets 41 and the inner soft rubber sheets 31 are made of the same material and have the same function. The two are provided to serve as a double-layer seal.

[0025] Preferably, the spacing between a row of inner soft rubber sheets 31 is zero, and the spacing between a row of outer soft rubber sheets 41 is also zero. This arrangement can further improve the sealing between the inner sealing rubber sheet 3 and the outer sealing rubber sheet 4 and the conveyor belt 1.

[0026] Furthermore, a clearance gap 21 is provided at the bottom of the front and rear sides of the material guide trough body 2. The clearance gap 21 is a channel for the material on the conveyor belt 1 to pass through. That is to say, the conveyor belt 1 can move the material away from the material guide trough body 2 when it is running. At the same time, the clearance gap 21 is also a position where dust is easily generated. Therefore, a dust collecting hood 5 opposite to the clearance gap 21 is fixedly connected to the front and rear sides of the material guide trough body 2. The function of the dust collecting hood 5 is to collect the dust discharged from the clearance gap 21.

[0027] Specifically, the cross-section of the dust hood 5 is an arc-shaped structure with the inner arc surface facing downward. An air collecting box 51 is fixedly provided on the top of the dust hood 5, and an exhaust pipe 511 is provided on the top of the air collecting box 51. When in use, the exhaust pipe 511 is connected to the external bag dust removal system through a pipeline. When the exhaust pipe 511 is exhausted, it can collect dust overflowing from the gap 21.

[0028] Furthermore, the clearance gap 21 is a circular arc surface structure with the inner arc surface facing the conveyor belt 1. The inner arc surface of the clearance gap 21 is fixedly connected with densely distributed cloth strips 6, and the bottom of the cloth strips 6 extends to the upper end surface of the conveyor belt 1. The densely distributed cloth strips 6 can prevent the raised dust from diffusing outward, so that the material dust can naturally settle in the material guide trough 2, reducing material loss.

[0029] In this embodiment, evenly distributed cloth ropes 7 are suspended on both sides of the dust hood 5. The bottoms of the cloth ropes 7 extend to the upper end surface of the conveyor belt 1. The cloth ropes 7 are densely arranged to reduce the amount of dust that diffuses outward from the dust hood 5, allowing the dust hood 5 to fully collect the dust, thereby improving environmental performance.

[0030] In this embodiment, the width of the inner soft film 31 and the outer soft film 41 is at least 50 mm. The purpose of this setting is to avoid the misalignment of the inner soft film 31 and the outer soft film 41 in the stacked state, thereby ensuring the sealing between the inner sealing rubber plate 3 and the outer sealing rubber plate 4 and the conveyor belt 1.

[0031] In this embodiment, connecting holes 22 are formed on both sides of the material guide trough body 2 , and the inner sealing rubber plate 3 and the outer sealing rubber plate 4 are connected to the left and right side walls of the material guide trough body 2 through bolts and the connecting holes 22 .

[0032] Working principle: When in use, there is a sealed pipe above the material guide chute 2 to transmit the unloading material. When the material falls on the conveyor belt 1, the conveyor belt 1 is controlled to operate, and a row of inner soft rubber sheets 31 and a row of outer soft rubber sheets 41 are passively tilted and pressed against the conveyor belt 1. At this time, a row of inner soft rubber sheets 31 and a row of outer soft rubber sheets 41 can effectively prevent the dust generated by the impact of the falling material from overflowing from the left and right sides of the material guide chute 2, and then exhaust the air outward through the exhaust pipe 511. A small amount of dust overflowing from the gap 21 will be directly sucked away by the air collecting box 51 to avoid dust pollution.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
