DETAILED DESCRIPTION

[0026] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the directional terms such as "upper, lower, left, right, front, back" generally refer to the positions when the user uses it; "inside, outside" refer to the inside and outside of the corresponding component contour; "first direction" refers to the X direction shown in the drawings; "second direction" refers to the Y direction shown in the drawings; "third direction" refers to the Z direction shown in the drawings; in addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another.

[0028] According to the first embodiment of the present disclosure, as Figure 1 and Figure 2As shown, a spillage prevention skirt plate 1 for a belt conveyor 100 is provided. The spillage prevention skirt plate 1 is used to be arranged between the conveyor belt 3 and the loading chute 2 of the belt conveyor 100 and is used for dynamic sealing between the conveyor belt 3 and the loading chute 2 to prevent dust generated during the falling process of materials from overflowing through the gap between the loading chute 2 and the conveyor belt 3. The conveyor belt 3 can be arranged on troughing idlers 4, and the troughing idlers 4 can drive the conveyor belt 3 to move continuously during the movement process. Schematically, the spillage prevention skirt plate 1 can include a skirt plate body 11 and an adjustment mechanism 12. Among them, the skirt plate body 11 can include a fixing part 111 and a sealing part 112. During the installation process, the fixing part 111 is used to connect with the side plate 21 of the loading chute 2. Optionally, the fixing part 111 can be installed on the side plate 21 by clamping with angle aluminum 5 or by bolt fastening. Correspondingly, after the fixing part 111 is installed on the side plate 21, the sealing part 112 can fit on the conveyor belt 3 and form a dynamic seal with the conveyor belt 3. The adjustment mechanism 12 mentioned above can be arranged on the skirt plate body 11 between the fixing part 111 and the sealing part 112. When the spillage prevention skirt plate 1 is installed on the belt conveyor 100, the adjustment mechanism 12 is used to adjust the fitting pressure between the sealing part 112 and the conveyor belt 3. In the technical solution provided in this embodiment, when the spillage prevention skirt plate 1 is deformed, the adjustment mechanism 12 can adjust the fitting pressure between the sealing part 112 and the conveyor belt 3 to ensure that the sealing part 112 can fit on the conveyor belt 3 and form an effective dynamic seal with the conveyor belt 3, thereby avoiding the problem of dust overflow.

[0029] In some embodiments, as Figure 2 shown, the skirt plate body 11 mentioned above can also include a deformation part 113 connecting the fixing part 111 and the sealing part 112, and a threaded hole 13b is provided on the deformation part 113. Correspondingly, the adjustment mechanism 12 mentioned above can include an adjustment bolt 121. During the installation process, the adjustment bolt 121 can be screwed into the threaded hole 113b. In some application scenarios, the fixing part 111 can be connected to the side plate 21 of the loading chute 2, the sealing part 112 can be sealed and abutted against the conveyor belt 3, the deformation part 113 can be arranged opposite to the side plate 21 of the loading chute 2, and the adjustment bolt 121 can be abutted against the side plate 21 of the loading chute 2. During the use process, the adjustment bolt 121 can adjust the deformation of the deformation part 113 to adjust the fitting pressure. Here, it is worth noting that in order to enable those skilled in the art to better understand the adjustment scheme of the adjustment mechanism 12 in the present disclosure, the specific working process of the adjustment mechanism 12 will be described in detail below, specifically as follows:

[0030] During the continuous operation of the conveyor belt 3 to achieve material transfer, the sealing part 112 will be in direct contact with the transferred material and continuously abut and rub against the conveyor belt 3, which will cause the sealing part 112 to be deformed by heat. After a period of time or after the sealing part 112 is deformed by heat, the seal between the sealing part 112 and the conveyor belt 3 will become weak, and there will be a risk of material leakage or specific leakage between the two. At this time, the operator can turn the adjustment bolt 121, so that during the turning of the adjustment bolt 121, the deformation part 113 is forced to deform toward the side away from the side plate 21. Further, during the deformation of the deformation part 113, the sealing part 112 will be driven to approach the conveyor belt 3 and fit onto the conveyor belt 3 again, and the sealing part 112 can apply a set fitting pressure to the conveyor belt 3 to form an effective dynamic seal between the sealing part 112 and the conveyor belt 3. Optionally, the adjustment bolt 121 mentioned above can be a nylon bolt. When adjusting the fitting pressure, the screwing length of the nylon bolt screwed into the threaded hole 113b can be adjusted. The selection of the nylon bolt mainly takes advantage of the fact that the nylon bolt is not easy to rust and has low cost.

[0031] Here, it should also be noted that in the technical solution proposed by the present disclosure, in addition to being able to perform adjustment when the sealing part 112 is deformed, in some application scenarios, the adjustment mechanism 12 can also pre-adjust the fitting pressure between the sealing part 112 and the conveyor belt 3 according to the different materials of the sealing part 112 and the fitting pressure requirements in the early stage of conveying.

[0032] In some embodiments, in order to enable the deformation part 113 to be reliably deformed under the adjustment of the adjustment bolt 121 and for the convenience of the operator to operate with less effort, as Figure 2 shown, a groove 113a can be provided on the surface of the deformation part 113 that abuts against the side plate 21. Correspondingly, the threaded hole 113b mentioned above can pass through the groove 113a so that the positions of the threaded hole 113b and the groove 113a correspond to each other.

[0033] In some embodiments, as Figure 3As shown, there can be multiple threaded holes 113b on the deformation part 113. And the multiple threaded holes 113b are arranged at intervals along the first direction of the skirt body 11. Correspondingly, multiple adjusting bolts 121 can be provided. Each adjusting bolt 121 can be disposed in the threaded hole 113b one by one. When it is necessary to adjust the fitting pressure between the sealing part 112 and the conveyor belt 3, a uniform force can be applied to the deformation part 113 by adjusting the multiple adjusting bolts 121, so that the entire deformation part 113 deforms toward the side away from the side plate 21, thereby driving the entire sealing part 112 to be evenly fitted to the conveyor belt 3. The setting of the multiple threaded holes 113b on the deformation part 113 can improve the adjustment reliability of the adjustment mechanism 12.

[0034] In some embodiments, the sealing part 112 mentioned above may include a first sealing part 1121. Schematically, as Figure 2 shown, the first sealing part 1121 may include a first sealing body 1121a and at least one first sealing protrusion 1121b extending along the first direction (such as the x direction in Figure 3 ) of the skirt body 11. The setting of the first sealing protrusion 1121b can enable the sealing part 112 to be well fitted to the conveyor belt 3 and form an effective dynamic seal, thereby avoiding the problem of dust overflow.

[0035] In some application scenarios, multiple first sealing protrusions 1121b mentioned above can be provided. Specifically, the multiple first sealing protrusions 1121b are arranged at intervals along the second direction (such as the y direction in Figure 3 ) perpendicular to the first direction of the skirt body 11 on the first sealing body 1121a. And each of the first sealing protrusions 1121b is parallel to each other. The setting of the multiple first sealing protrusions 1121b improves the sealing reliability of the first sealing part 1121. Preferably, there can be 3 first sealing protrusions 1121b. Of course, the number of the first sealing protrusions 1121b can also be other numbers, which is only for illustrative purposes here, and those skilled in the art can choose according to the actual situation.

[0036] As Figure 2 and Figure 3 shown, the number of the first sealing protrusions 1121b can be three, and they all extend along the first direction and are arranged at intervals in the second direction. Such a setting method enables the first sealing part 1121 to form three seals with the conveyor belt through the three first sealing protrusions 1121b, further improving the sealing reliability of the first sealing part 1121.

[0037] Here, it should be noted that, in order to enable those skilled in the art to better understand the thickness of the first sealing protrusion 1121b mentioned in this embodiment, a third direction of the skirt body 11 is also defined (such as Figure 3 the z-direction in). The first direction, the second direction, and the third direction are perpendicular to each other. The thickness formed by the first sealing protrusion 1121b extending along the third direction of the skirt body 11 is the thickness of the first sealing protrusion 1121b.

[0038] The thickness of the first sealing protrusion 1121b in the third direction can be set accordingly according to actual needs. In some application scenarios, the thickness of the first sealing protrusion 1121b can also be correspondingly limited. Schematically, the thickness of the first sealing protrusion 1121b is greater than or equal to the thickness of the first sealing skirt body 1121a. Such a setting method can enable the first sealing protrusion 1121b to have sufficient wear surplus to ensure that after being adjusted by the adjusting bolt 121 later, the first sealing portion 1121 can still form an effective dynamic seal with the conveyor belt 3.

[0039] In some embodiments, the sealing portion 112 described above may further include a second sealing portion 1122. Schematically, as Figure 2 shown, the second sealing portion 1122 may include a second sealing body 1122a and at least one second sealing protrusion 1122b extending along the first direction of the skirt body 11 (such as Figure 3 the x-direction in). Among them, the second sealing protrusion 1122b is disposed opposite to the first sealing protrusion 1121b mentioned above. After installation, the bending deformation directions of the first sealing protrusion 1121b and the second sealing protrusion 1122b are opposite, so that the first sealing protrusion 1121b and the second sealing protrusion 1122b can form a "herringbone" sealing structure, and finally two sets of sealing structures are formed between the side plate 21 and the conveyor belt 3 through the first sealing protrusion 1121b and the second sealing protrusion 1122b. The setting of the second sealing protrusion 1122b can still keep in close contact with the conveyor belt 3 and form an effective dynamic seal when the first sealing protrusion 1121b fails, for example, when longitudinal wave deformation occurs during the transportation of high-temperature materials, further improving the sealing reliability.

[0040] In some embodiments, the fixing portion 111, the deformation portion 113, and the sealing portion 112 mentioned above are integrally formed. Such a structural method enables the anti-spill skirt 1 to be quickly formed, with low manufacturing cost and simple process. Of course, the structural method of the fixing portion 111, the deformation portion 113, and the sealing portion 112 can also be a segmented structure, which is not limited here, and those skilled in the art can adjust according to the actual situation.

[0041] Optionally, the materials of the fixing portion 111, the deforming portion 113, and the sealing portion 112 include, but are not limited to, polyurethane, and may also be integrally formed of other sealing materials well-known to those skilled in the art. In this embodiment, the polyurethane material is selected mainly for its advantages such as good wear resistance, high strength, and wide hardness range.

[0042] According to the second embodiment of the present disclosure, as Figure 1 shown, a belt conveyor 100 is provided. Figure 1 FIG. is a partial schematic view of the belt conveyor observed in the material conveying direction. Among them, the belt conveyor has a left-right symmetrical structure. Only the left side is schematically shown in the figure. Along the central axis in the up-down direction of the drawing, the right side is a mirror structure corresponding to the left-right symmetry. For the convenience of understanding, the embodiments of the present disclosure will be described in detail only by taking the left side as an example. The belt conveyor 100 may include a conveyor belt 3, a feed chute 2, and the anti-spill skirt plate 1 mentioned above. In this embodiment, the belt conveyor 100 provided with the above anti-spill skirt plate 1 can have good operation safety and avoid physical damage to relevant operators caused by dust spillage.

[0043] For those skilled in the art to better understand the adjustment process of the belt conveyor 100 provided in this embodiment after installing the anti-spill skirt plate 1, the adjustment process will be described in detail below, specifically as follows:

[0044] As Figure 1 and Figure 2 shown, when the belt conveyor 100 conveys materials, the continuously running conveyor belt 3 will cause the sealing portion 112 to deform, and the sealing portion 112 cannot fit with the conveyor belt 3, resulting in the failure of the dynamic seal between the sealing portion 112 and the conveyor belt 3. At this time, the operator can adjust the adjusting bolt 121 so that the adjusting bolt 121 is screwed inward toward the side close to the side plate 21, thereby causing the deforming portion 113 to deform away from the side plate 21, and finally driving the sealing portion 112 to fit onto the conveyor belt 3 again, restoring the dynamic seal between the sealing portion 112 and the conveyor belt 3.

[0045] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0046] In addition, it should be noted that in the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0047] In addition, any combination can be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should equally be regarded as the content disclosed by the present disclosure.
