Description

Technical Field

[0001] The present disclosure relates to the technical field of overflow prevention skirt plates, and in particular to an overflow prevention skirt plate structure and a material conveying device. Background Art

[0002] The material conveying device generally includes a belt, a roller and a material guide trough. The material falls from the material guide trough onto the belt, rolls and drives the belt to rotate, thereby realizing the conveyance of the material on the belt.

[0003] In the process of materials falling from the material guide chute onto the belt, the materials can easily splash onto the outside of the belt due to their own potential energy. In order to solve the above problem, an anti-overflow skirt structure is generally added between the material guide chute and the belt. In order to better achieve the anti-splashing effect, the anti-overflow skirt structure generally needs to maintain close contact with the belt at all times, resulting in wear of the anti-overflow skirt. Once the anti-overflow skirt structure is worn, the anti-overflow skirt needs to be replaced as a whole, which increases maintenance costs. Utility Model Content

DETAILED DESCRIPTION

[0030] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0031] In the present disclosure, unless otherwise stated, directional terms such as "length direction" are defined based on the baffle. Figure 3 , Attachment Figure 4 The direction of the drawing shown in the figure is defined by the directional words such as "vertical direction" used, which are defined based on the actual use scenario of the overflow skirt structure. For details, please refer to the attached Figure 1 The directions of the drawings shown are defined only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, it cannot be understood as a limitation of the present disclosure. The terms "inside and outside" refer to the inside and outside of the corresponding structural contour.

[0032] In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order or importance. In addition, in the description with reference to the drawings, the same number in different drawings represents the same element.

[0033] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0034] refer to Figures 1 to 6As shown, the first aspect of the present disclosure provides an anti-overflow skirt structure 1, including a baffle 10 and a wear-resistant plate 20, the baffle 10 includes a first plate body 11 and a second plate body 12 connected to each other, the first plate body 11 extends in a vertical direction, the end of the first plate body 11 away from the second plate body 12 is used to connect with the side plate 301 of the material guide trough 300, and the end of the second plate body 12 away from the first plate body 11 is bent toward the inside of the material guide trough 300; the wear-resistant plate 20 is detachably connected to the side wall of the second plate body 12 on the side away from the material guide trough 300, and is used to abut against the outer peripheral surface of the belt 100.

[0035] Through the above technical scheme, firstly, a wear-resistant plate 20 is arranged on the second plate body 12, and the wear-resistant plate 20 abuts against the outer peripheral surface of the belt 100, so that in the process of the belt 100 moving relative to the anti-overflow skirt structure 1, the baffle 10 will not come into direct contact with the belt 100, thereby avoiding the problem of wear of the baffle 10, and since the wear-resistant plate 20 is detachably connected to the second plate body 12, when the wear-resistant plate 20 is severely worn, the wear-resistant plate 20 can be directly replaced without replacing the baffle 10, thereby significantly reducing the maintenance cost of the anti-overflow skirt structure 1.

[0036] In addition, since the first plate body 11 extends in the vertical direction and a section of the second plate body 12 away from the first plate body 11 is bent toward the inside of the material guide trough 300, the second plate body 12 can have a larger relative area with the belt 100, thereby facilitating the arrangement of the wear-resistant plate 20 and the contact between the wear-resistant plate 20 and the belt 100, so as to achieve better anti-overflow and anti-splash effects.

[0037] In order to meet the anti-overflow requirements for belts 100 with different inclination angles, in an embodiment provided by the present disclosure, optionally, the angle between the first plate 11 and the second plate 12 can be 120° to 145°. That is, for belts 100 with different inclination angles, a baffle 10 adapted to the angle can be adaptively selected to achieve a better anti-overflow effect.

[0038] In an exemplary embodiment provided by the present disclosure, the angle between the first plate body 11 and the second plate body 12 is 135°.

[0039] In addition, the above-mentioned baffle 10 can be made of a flexible material, and the flexible material has a certain elasticity. In this way, on the one hand, it can avoid the baffle 10 from scratching the belt 100 during the transmission of the belt 100, thereby causing damage to the belt 100. On the other hand, the elastic baffle 10 can also play a role in correcting the belt 100 during the transmission of the belt 100. Specifically, since the baffle 10 made of flexible material has a certain elasticity, when the belt 100 deviates, the baffle 10 will be deformed and generate an elastic force in the opposite direction of the deviation of the belt 100 to limit the deviation of the belt 100, and enable the wear-resistant parts to automatically fit on the belt 100 to achieve a better sealing effect.

[0040] In an exemplary embodiment provided by the present disclosure, the baffle 10 may be made of materials such as styrene-butadiene rubber elastomer or silicone rubber elastomer.

[0041] In addition, the wear-resistant plate 20 may be made of polyurethane material or rubber material, both of which have excellent wear resistance and are unlikely to cause damage to the belt 100 when in contact with the belt 100 .

[0042] Alternatively, if Figure 1 to Figure 2 As shown, the second plate body 12 may include a plane section 121 and an arc section 122, the arc section 122 is connected between the first plate body 11 and the plane section 121, the extension direction of the plane section 121 is parallel to the inclination direction of the belt 100, and the wear-resistant plate 20 is connected to the plane section 121. In this way, by setting the arc section 122, the extension direction of the plane section 121 can be changed, ensuring that the wear-resistant plate 20 set on the plane section 121 is parallel to the inclination direction of the belt 100, so that the wear-resistant plate 20 can be completely in contact with the belt 100, increasing the contact area with the belt 100, and further improving the sealing effect.

[0043] Alternatively, if Figures 4 to 5 As shown, along the length direction of the baffle 10, a plurality of slots 120 are formed on the second plate body 12, and a plurality of blocks 21 are formed on the side of the wear-resistant plate 20 close to the second plate body 12, each slot 120 is arranged in one-to-one correspondence with each block 21, and each block 21 is engaged in the slot 120 corresponding thereto; or, along the length direction of the baffle 10, a plurality of blocks 21 are formed on the second plate body 12, and a plurality of slots 120 are formed on the side of the wear-resistant plate 20 close to the second plate body 12, each block 21 is arranged in one-to-one correspondence with each slot 120, and each block 21 is engaged in the slot 120 corresponding thereto. In this way, the wear-resistant plate 20 can be quickly disassembled and assembled without the aid of tools.

[0044] Furthermore, since the wear-resistant plate 20 always abuts against the outer peripheral surface of the belt 100 , the engagement between the clamping block 21 and the clamping groove 120 can be made more stable and less likely to fall off.

[0045] In other embodiments provided in the present disclosure, the wear-resistant plate 20 may also have a first mounting hole and a second mounting hole on the second plate body 12, and the overflow prevention skirt structure 1 also includes fasteners, which pass through the first mounting hole and the second mounting hole in sequence, thereby fastening the wear-resistant plate 20 to the second plate body 12.

[0046] Optionally, the spacing between two adjacent slots 120 is equal, and the spacing between two adjacent blocks 21 is equal. The evenly distributed slots 120 and blocks 21 can make the wear-resistant plate 20 and the second plate body 12 of the bottom plate more tightly fixed.

[0047] Alternatively, if Figure 3 As shown, the anti-overflow skirt structure 1 further includes a spray assembly 30, which is disposed on the baffle 10 and is used to spray the belt 100. In this way, while the baffle 10 and the wear-resistant plate 20 play a role in preventing the material from splashing, the spray assembly 30 can spray the material, thereby effectively suppressing the dust generated during the transmission process of the belt 100, and having a certain cleaning effect on the belt 100.

[0048] Specifically, in this application, Figures 3 to 5 As shown, the spray assembly 30 may also include a spray pipe 31, which has a plurality of spray holes 16; a through hole 14 is also formed on the baffle plate 10, which penetrates along its own length direction, and a plurality of spray holes 15 are formed on the side wall of the baffle plate 10 away from the material guide trough 300. The plurality of spray holes 15 are arranged at intervals along the length direction of the baffle plate 10, and each spray hole 15 is connected to the through hole 14; the spray pipe 31 is penetrated in the through hole 14, and each spray hole 16 on the spray pipe 31 is arranged one-to-one with each spray hole 15 on the baffle plate 10, so that the liquid in the spray pipe 31 can be sprayed out through the spray hole 15. In this way, during the transmission of the belt 100, the spray assembly 30 is started, and the spray pipe 31 penetrating the through hole 14 of the baffle 10 is filled with water for spraying. The water is sprayed out from the multiple spray holes 16 set on the spray pipe 31, and is sprayed onto the belt 100 through the spray holes 15 formed on the baffle 10, thereby suppressing dust and cleaning the belt 100.

[0049] In the present disclosure, the above-mentioned spray assembly 30 may also include a water tank (not shown) and a water pump (not shown), the water inlet of the water pump is connected to the water tank, and the water outlet of the water pump is connected to the end of the spray pipe 31 away from the baffle 10, so that when the belt 100 is running, the water pump starts, water enters the spray pipe 31 and is sprayed out through the injection hole 16 and the spray hole 15 in sequence.

[0050] In the embodiment where the baffle 10 includes a first plate body 11 and a second plate body 12 , the through hole 14 may be formed on the first plate body 11 or on the second plate body 12 .

[0051] Optionally, along the length direction of the baffle 10, the spacing between two adjacent spray holes 15 is equal. The spacing between two adjacent spray holes 15 is equal, which can make the sprayed water mist more uniform, thereby ensuring the cleaning effect of the belt 100 and reducing or avoiding leaving cleaning dead corners.

[0052] like Figure 1 to Figure 2 As shown, the second aspect of the present disclosure provides a material conveying device 600, comprising a belt 100, a roller 200, a material guide trough 300 and the above anti-overflow skirt plate structure 1, wherein the roller 200 is used to drive the belt 100 to rotate, the material guide trough 300 is arranged above the belt 100, and the anti-overflow skirt plate structure 1 is installed on the side wall of the material guide trough 300 and abuts against the outer peripheral surface of the belt 100. The material conveying device 600 has all the beneficial effects of the above anti-overflow skirt plate structure 1, which will not be described in detail in the present disclosure.

[0053] In addition, if Figure 1 As shown, a clamp 302 is also provided on the side wall of the material guiding trough 300 , and the clamp 302 detachably clamps the anti-overflow skirt plate structure 1 on the side wall of the material guiding trough 300 .

[0054] Alternatively, if Figure 3 , Figure 6 As shown, the anti-overflow skirt structure 1 also includes a spray assembly 30 for spraying to the belt 100, and the material conveying device 600 also includes a controller 400 and a speed sensor 500. The speed sensor 500 is arranged opposite to the roller 200 and is used to detect the start and stop status of the roller 200. The controller 400 is respectively connected to the spray assembly 30 and the speed sensor 500 for signals. The controller 400 is used to control the start and stop of the spray assembly 30 according to the detection result of the speed sensor 500. Specifically, the speed sensor 500 arranged opposite to the drum 200 can detect the running state of the drum 200, and the speed sensor 500 is connected to the controller 400 signal, so that when the speed sensor 500 detects that the drum 200 is rotating (that is, the drum 200 is started), the controller 400 receives the signal of the speed sensor 500, and then controls the spray component 30 to start, and sprays the belt 100 driven by the drum 200, so as to achieve the purpose of reducing dust and cleaning the belt 100; similarly, when the speed sensor 500 detects that the drum 200 stops rotating (that is, the drum 200 is closed), the controller 400 receives the signal of the speed sensor 500, and then controls the spray component 30 to close, and stops spraying the belt 100 that is no longer running, so as to avoid waste of water.

[0055] In addition, for an embodiment in which the spray assembly 30 also includes a water pump, the controller 400 can be connected to the water pump and control the start and stop of the water pump according to the signal input by the speed sensor 500, thereby controlling the spray hole 15 to spray or stop spraying.

Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0057] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0058] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
