Its structure is basically to set side panels on both sides of the conveyor belt, set a top panel between the side panels, and install anti-overflow skirt panels at the bottom of the side panels. The anti-overflow skirt panels are made of soft rubber. During use, the anti-overflow skirt panels and the belt are worn by each other. They are wearing parts, so they need to be replaced frequently because of the wear and tear. The operation and maintenance costs are very high.

DETAILED DESCRIPTION

[0022] The present invention is not limited to the following embodiments, and specific implementation methods can be determined based on the technical solutions of the present invention and actual conditions.

[0023] In the present invention, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0024] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0025] Implementation 1: As attached Figure 1 、 2 As shown, the fully enclosed material guide trough includes a bracket 1, a roller group 2, a conveyor belt 3, a side plate 4 and a top plate 5. The conveyor belt 3 is provided on the roller group 2. A side plate 4 is respectively installed on both sides of the conveyor belt 3 through the bracket 1. A top plate 5 is sealed between the two side plates 4. A first hard wear-resistant baffle 6 whose height can be adjusted up and down relative to the conveyor belt 3 is respectively installed at the bottom of the two side plates 4. The bottom of the first hard wear-resistant baffle 6 is in sliding contact with the conveyor belt 3 or is at a distance S from it, and the S distance is 0 mm to 20 mm.

[0026] When the existing guide trough is used to transport materials such as coal gangue and coal, the rubber anti-overflow skirt will be worn out after running for a certain period of time. When the part of the bottom of the rubber anti-overflow skirt that contacts the conveyor belt is worn out, the rubber anti-overflow skirt is soft in texture and cannot block the material. As a result, the rubber anti-overflow skirt is lifted outward under the push of the material, thereby losing the sealing effect on the upper space of the conveyor belt. Therefore, the rubber anti-overflow skirt needs to be replaced frequently. In this device, the first hard wear-resistant baffle 6 is provided. First, the first hard wear-resistant baffle 6 is not easy to wear, and since the first hard wear-resistant baffle 6 has a stable structure, it will not be deformed under the push of the material, that is, it can ensure that the distance between the first hard wear-resistant baffle 6 and the conveyor belt 3 remains basically unchanged during long-term operation. In addition, since the first hard wear-resistant baffle 6 is stable, it will not be deformed under the push of the material. That is, it can ensure that the distance between the first hard wear-resistant baffle 6 and the conveyor belt 3 remains basically unchanged during long-term operation. The gap between the bottom of the wear-resistant baffle 6 and the conveyor belt 3 is small, while the volume of the conveyed materials such as gangue and coal is relatively large. These materials are not only unable to pass through the gap between the bottom of the first hard wear-resistant baffle 6 and the conveyor belt 3, but also block the gap. Therefore, the first hard wear-resistant baffle 6 can achieve a good sealing effect on the material conveying space above the conveyor belt 3. In addition, since the height of the first hard wear-resistant baffle 6 can be adjusted up and down, the distance between the first hard wear-resistant baffle 6 and the conveyor belt 3 can be flexibly adjusted according to the volume of the material conveyed on the conveyor belt 3. Specifically, based on the premise that the first hard wear-resistant baffle 6 can achieve a good sealing effect on the material conveying space above the conveyor belt 3, in this embodiment, the bottom of the first hard wear-resistant baffle 6 is in sliding contact with the conveyor belt 3. In summary, by using the first hard wear-resistant baffle 6 to replace the traditional rubber anti-overflow skirt in this device, while ensuring the sealing effect, it is not easy to wear itself and has a long service life, thereby reducing the maintenance workload of the material guide trough and reducing the operating cost of the material guide trough.

[0027] The above implementation may be further optimized and / or improved according to actual needs:

[0028] Specifically, the side plate 4 is provided with a height adjustment hole, and the first hard wear-resistant baffle 6 is fixedly installed in the height adjustment hole of the side plate 4 by a first adjustment bolt and a first fastening nut. As a result, the installation height of the first hard wear-resistant baffle 6 can be adjusted up and down, thereby adjusting the distance between the bottom of the first hard wear-resistant baffle 6 and the conveyor belt 3.

[0029] As attached Figure 1 、 2As shown, a fixed baffle 7 is respectively provided on the outer side of the two side panels 4, and the lower end of the fixed baffle 7 is a certain distance away from the conveyor belt 3. A second hard wear-resistant baffle 11, whose height can be adjusted up and down relative to the conveyor belt, is installed on the side panel corresponding to the outer position of the fixed baffle 7 through a height adjustment mechanism. The inner surface of the second hard wear-resistant baffle 11 is in contact with the outer surface of the fixed baffle 7, and the bottom of the second hard wear-resistant baffle 11 is in sliding contact with the conveyor belt 3 or is at a distance Y, and the Y distance is 0 mm to 5 mm. The principle is the same as that of the first hard wear-resistant baffle 6. The distance between the bottom of the second hard wear-resistant baffle 11 and the conveyor belt is small, which is sufficient to ensure a good sealing effect on the material conveying space above the conveyor belt 3. Therefore, the second hard wear-resistant baffle 11 and the fixed plate form a second layer of sealing structure, further improving the sealing effect of the device. In addition, since the height of the second hard wear-resistant baffle 11 is adjustable, when the bottom of the second hard wear-resistant baffle 11 is worn after long-term use, the height adjustment mechanism can be used to make the second hard wear-resistant baffle 11 descend along the outer side of the fixed baffle 7 so that its bottom is in sliding contact with the conveyor belt 3 again or at a distance Y, thereby eliminating the need to replace a new second hard wear-resistant baffle 11, reducing maintenance costs. In this embodiment, the bottom of the second hard wear-resistant baffle 6 is in sliding contact with the conveyor belt 3.

[0030] As attached Figure 1 、 2 As shown, the height adjustment mechanism includes a first mounting seat 8, an adjusting rod 9, a second mounting seat 10, a second adjusting bolt 15 and a second fastening nut. A first mounting seat 8 is provided on the outer side of the side plate 4 corresponding to the upper side position of the fixed baffle 7. The first mounting seat 8 is provided with a first strip slot 13, and the adjusting rod 9 is provided with a second strip slot 14. The second adjusting bolt 15 passes through the first strip slot 13 and the second strip slot 14 in sequence and is screwed with a second fastening nut to fix the first mounting seat 8 and the adjusting rod 9 together. The adjusting rod 9 is hinged with a second mounting seat 10 that can rotate relative to the adjusting rod 9 and can be locked after rotation. A second hard wear-resistant baffle 11 is installed on the second mounting seat 10. According to requirements, the adjusting rod 9 and the second mounting seat 10 are hingedly connected by a third adjusting bolt and a third fastening nut, so that the second mounting seat 10 can be rotated relative to the adjusting rod 9 and locked. Therefore, by adjusting the installation position and angle of the adjusting rod 9 and the angle of the second mounting seat 10, the second hard wear-resistant baffle 11 can be moved up or down along the outer surface of the fixed baffle 7, thereby realizing the problem of adjusting the height of the second hard wear-resistant baffle 11.

[0031] Preferably, the first hard wear-resistant baffle 6 is a polymer plate, which has excellent wear resistance, stable structure and light weight.

[0032] Preferably, the second hard wear-resistant baffle 11 is a polymer plate, which has excellent wear resistance, stable structure and light weight.

[0033] Preferably, the polymer sheet is an ultra-high molecular weight polyethylene sheet. The molecular weight of the ultra-high molecular weight polyethylene sheet is 5 million to 9 million. The ultra-high molecular weight polyethylene sheet has the characteristics of self-lubrication and low friction coefficient, so it has excellent wear resistance, is not easy to be worn, and has a long service life.

[0034] As attached Figure 1 、 2 As shown, the side plate 4, the first hard wear-resistant baffle 6, the second hard wear-resistant baffle 11, the fixed baffle 7 and the conveyor belt 3 enclose a dust suppression chamber 12 whose length is parallel to the length direction of the conveyor belt 3. A spray nozzle 16 is provided in the dust suppression chamber 12. The cross section of the dust suppression chamber 12 is an approximately closed triangle. In this device, the dust suppression chamber 12 is formed by the arrangement of the first hard wear-resistant baffle 6, the second hard wear-resistant baffle 11 and the fixed baffle 7, which is equivalent to forming two auxiliary sealing spaces on both sides of the guide trough. A spray nozzle 16 is installed in the dust suppression chamber 12. The spray sprayed by the spray nozzle 16 can suppress a small amount of dust that overflows from the primary seal, thereby preventing dust from overflowing. According to needs, the spray nozzle 16 can be provided at the inlet end of the dust suppression chamber, and the spraying direction of the spray nozzle 16 is parallel to the length direction of the dust suppression chamber 12.

[0035] As attached Figure 1 、 2 As shown, the bottom of the first hard wear-resistant baffle 6 is an inclined plane adapted to the inclination angles of both sides of the conveyor belt 3. This increases the sliding contact area between the first hard wear-resistant baffle 6 and the conveyor belt 3 and improves the sealing performance.

[0036] As attached Figure 1 、 2 As shown, the bottom of the second hard wear-resistant baffle 11 is an arc surface. Therefore, when the bottom of the second hard wear-resistant baffle 11 is worn after long-term operation, the height of the second hard wear-resistant baffle 11 can be adjusted to ensure that the second hard wear-resistant baffle 11 can still slide in contact with the conveyor belt 3.

[0037] Example 2: As shown in the attached Figure 3 As shown, this embodiment differs from the first embodiment only in that the bottom of the first hard wear-resistant baffle 6 is spaced a distance S of 20 mm from the conveyor belt 3, and the bottom of the second hard wear-resistant baffle 11 is spaced a distance Y of 5 mm from the conveyor belt 3. This makes it suitable for conveying larger volumes of material, and because neither the first hard wear-resistant baffle 6 nor the second hard wear-resistant baffle 11 contacts the conveyor belt, they are not subject to wear and do not affect the deflection and return of the conveyor belt.

[0038] Example 3: As shown in the attached Figure 4As shown, this embodiment differs from the first embodiment only in that the bottom of the first hard wear-resistant baffle 6 is spaced 5 mm from the conveyor belt 3 by a distance S, and the bottom of the second hard wear-resistant baffle 11 is spaced 2 mm from the conveyor belt 3 by a distance Y. This makes it suitable for conveying medium-volume materials. Furthermore, since neither the first hard wear-resistant baffle 6 nor the second hard wear-resistant baffle 11 contacts the conveyor belt, they are not subject to wear and do not affect the deflection and return of the conveyor belt.

[0039] Example 4: As shown in the attached Figure 5 As shown, this embodiment differs from the first embodiment only in that the bottom of the first hard wear-resistant baffle 6 is spaced a distance S of 2 mm from the conveyor belt 3, and the bottom of the second hard wear-resistant baffle 11 is spaced a distance Y of 0.5 mm from the conveyor belt 3. This makes it suitable for conveying smaller materials, and because neither the first hard wear-resistant baffle 6 nor the second hard wear-resistant baffle 11 contacts the conveyor belt, they are not subject to wear and do not affect the deflection and return of the conveyor belt.

[0040] The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
