[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0039] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a skirted anti-accumulation device, which is installed on a belt conveyor 1. The belt conveyor 1 includes a belt 11, and a skirted conveyor belt 12 is provided on the edge of the belt 11. The skirted conveyor belt 12 extends along the extension direction of the belt 11 (e.g., ...). Figure 1 The skirt anti-accumulation device (shown in the X direction) abuts against the outer surface of the edge of the belt 11. The skirt anti-accumulation device includes: a push plate 2 and a drive mechanism 3.
[0040] Specifically, the pusher plate 2 is located on the outer side of the skirted conveyor belt 12, and the pusher plate 2 can move along the width direction of the belt 11 (e.g., Figure 1 , Figure 2 , Figure 3 and Figure 5 The Y direction shown) is in the first position (as shown) Figure 2 The position of push plate 2 shown in the figure) and the second position (as shown in the figure) Figure 3 The push plate 2 moves between the positions shown in the diagram; when the push plate 2 moves to the first position, it applies a force to the skirted conveyor belt 12, causing it to deform. When the push plate 2 moves to the second position, it separates from the skirted conveyor belt 12. For example, the push plate 2 is made of high-molecular-weight polyethylene, which provides good wear resistance and anti-slip properties.
[0041] The drive mechanism 3 is connected to the push plate 2 and is used to drive the push plate 2 to move along the Y direction of the belt 11.
[0042] This application, by setting up a push plate 2 and a drive mechanism 3 connected to the push plate 2, enables the push plate 2 to reciprocate along the Y direction using the drive mechanism 3. Specifically, when the push plate 2 moves to the first position, the push plate 2 contacts the skirt conveyor belt 12 and causes the skirt conveyor belt 12 to deform. When the push plate 2 moves to the second position, the push plate 2 separates from the skirt conveyor belt 12. By driving the push plate repeatedly between the first and second positions through the drive mechanism 3, the material accumulated on the skirt conveyor belt 12 is disturbed and falls off the skirt conveyor belt, effectively preventing material from accumulating on the skirt conveyor belt 12, thereby reducing material consumption and the risk of mixing different batches of material.
[0043] Further, refer to Figure 2 and Figure 3 There are two skirted conveyor belts 12 and two push plates 2. The two skirted conveyor belts 12 are respectively attached to the two sides of the belt 11, and the two push plates 2 are respectively located on the outside of the two skirted conveyor belts 12.
[0044] Specifically, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the drive mechanism 3 includes a bracket 31, a motor 35, a drive gear 32, two driven gears 33, two rockers 34, and two guide mechanisms 4.
[0045] A support 31 spans across the belt conveyor 1 along the Y direction of the belt 11 above the belt conveyor 1. Exemplarily, the support 31 is constructed from welded hollow rectangular steel tubing, with reinforcing ribs at its bottom. In some embodiments, a mounting plate 36 is also provided on the upper surface of the support 31, and a shock-absorbing rubber pad (not shown in the figure) is provided at the connection between the mounting plate 36 and the support 31. This application provides a reliable basis for the stable operation of the motor 35 by setting up the support 31 and the mounting plate 36. Furthermore, by providing the shock-absorbing rubber pad, the vibration of the motor 35 on the support 31 and the mounting plate 36 is reduced, improving the stability of the device.
[0046] The drive gear 32 is rotatably disposed below the bracket 31.
[0047] The motor 35 is located above the bracket. The power output end of the motor 35 is connected to the drive gear 32 and is used to drive the drive gear 32 to rotate around the axis of the drive gear 32.
[0048] Two driven gears 33 are rotatably mounted below the bracket 31. The two driven gears 33 are arranged on both sides of the driving gear 32 along the Y direction of the belt 11 and mesh with the driving gear 32. The meshing transmission relationship between the driving gear 32 and the driven gears 33 provides a reliable power source for the device.
[0049] Of the two rocker arms 34, one rocker arm 34 is hinged at both ends to a driven gear 33 and a push plate 2 located on the same side, while the other rocker arm 34 is hinged to a driven gear 33 and a push plate 2 located on the opposite side. When the driven gear 33 rotates, it can transmit power to the push plate 2 through the rocker arm 34.
[0050] The push plate 2 is restricted by the guide mechanism 4 to only move in a straight line along the Y direction. Therefore, the driven gear 33 and the rocker arm 34 together constitute a crank-rocker mechanism. The power output by the motor 35 can drive the push plate 2 to move back and forth along the Y direction through this crank-rocker mechanism.
[0051] Optionally, the rocker arm 34 is connected to the push plate 2 via a self-lubricating bearing. Exemplarily, the rocker arm 34 is made of stainless steel. This application reduces friction at the connection between the rocker arm 34 and the push plate 2 by using a self-lubricating bearing, ensuring smooth movement at the connection point. Furthermore, the use of stainless steel for the rocker arm 34 provides excellent corrosion resistance and strength.
[0052] Further, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 Two guide mechanisms 4 are respectively connected to two push plates 2, and are used to guide the corresponding push plates 2 to move linearly along the Y direction of the belt 11. The guide mechanism 4 includes:
[0053] Positioning plate 41 is located on the outside of push plate 2, and positioning plate 41 is arranged parallel to push plate 2;
[0054] At least two guide rods 42 extend along the Y direction of the belt 11. The guide rods 42 are positioned between the positioning plate 41 and the push plate 2. One end of each guide rod 42 is slidably connected to the positioning plate 41, and the other end is fixedly connected to the push plate 2. For example, as shown... Figure 4 and Figure 6 As shown, the positioning plate 41 has a through hole 411 extending through the positioning plate 41 along the Y direction of the belt 11. The guide rod 42 is inserted into the through hole 411 and can slide within the through hole 411. The end of the guide rod 42 away from the push plate 2 is provided with an anti-disengagement buckle (not shown in the figure). The anti-disengagement buckle is used to restrict the guide rod 42 from coming out of the through hole 411, thereby ensuring that the push plate 2 can move stably along the Y direction of the belt 11.
[0055] It should be noted that multiple guide rods 42 can be equally spaced on the push plate 2 along the vertical direction of the push plate 2. The equally spaced multiple guide rods 42 can ensure that the push plate 2 moves stably along the Y direction.
[0056] In addition, such as Figure 1 , Figure 2 and Figure 3 As shown, the belt conveyor 1 also includes a first motor 13, a pulley side plate 14, and a pulley (not shown in the figure) disposed inside the pulley side plate 14.
[0057] Specifically, after the first motor 13 starts, its output drives the pulley inside the pulley side plate 14 to rotate. The rotation of the pulley provides power to the belt 11, causing the belt 11 and the skirted conveyor belt 12 to start running, and the material on the belt 11 begins to be conveyed. Then, the motor 35 is started, and the output of the motor 35 drives the drive gear 32 to rotate at high speed. Since the drive gear 32 meshes with the two driven gears 33 respectively, based on this transmission relationship and according to the transmission ratio between the drive gear 32 and the driven gears 33 preset by the operator, the driven gears 33 rotate at the corresponding speed below the preset transmission ratio. During the rotation of the driven gears 33, the rocker arm 34, which is hinged to the driven gears 33, also moves with the rotation of the driven gears 33. The power generated by the driven gears 33 can be transmitted through the rocker arm 34 to the push plate 2, which is hinged to the other end of the rocker arm 34. Guided and constrained by the guide rod 42, the pusher 2 moves back and forth along the Y direction between the first and second positions, periodically pushing the skirted conveyor belt 12 to continuously agitate the material accumulated on the skirted conveyor belt 12 near the belt 11. The first and second positions represent the extreme positions of the pusher 2's movement. Through the coordinated operation of the motor 35, the drive gear 32, the driven gear 33, the rocker arm 34, and the pusher 2, the skirted conveyor belt 3 is periodically and regularly pushed along the Y direction, causing the material accumulated on the skirted conveyor belt 12 to be agitated and fall off, effectively preventing material accumulation on the skirted conveyor belt 12, thereby reducing material consumption and the risk of mixing different batches of material.
[0058] Optionally, such as Figure 7 As shown, the lower surface of the driven gear 33 is provided with a hinge shaft 331. One end of the rocker arm 34 is hinged to the driven gear 33 through the hinge shaft. The distance between the axis of the hinge shaft 331 and the central axis of the driven gear 33 is 1 / 5 to 1 / 4 of the length of the rocker arm 34.
[0059] In some embodiments, the transmission ratio between the driving gear 32 and the driven gear 33 is 1:2 to 1:3. For example, the tooth surface of the driven gear 33 is provided with a wear-resistant coating.
[0060] The skirt-edge anti-material accumulation device of this utility model sets the distance between the axis of the hinge shaft 331 and the central axis of the driven gear 33 to 1 / 5 to 1 / 4 of the length of the rocker arm 34, and sets the transmission ratio between the driving gear 32 and the driven gear 33 to 1:2 to 1:3. This ensures the rationality of the movement frequency of the push plate 2, thereby improving the stability and feasibility of the skirt-edge anti-material accumulation device. In addition, by coating the tooth surface of the driven gear 33 with a wear-resistant coating, the durability of the device can be further improved.
[0061] In some implementations, reference Figure 2 and Figure 3 The push plate 2 has a corrugated anti-slip texture on the side that contacts the skirt conveyor belt 12. For example, the push plate 2 is made of high-molecular-weight polyethylene. By providing the corrugated anti-slip texture on the push plate 2, this application can increase the friction with the skirt conveyor belt 12, thereby making the pushing effect of the push plate 2 on the skirt conveyor belt 12 more significant and more effectively preventing material from accumulating on the skirt conveyor belt.
[0062] Optionally, the positioning plate 41 is provided with a waist-shaped hole (not shown in the figure), which extends along the Y direction. A bolt is installed in the waist-shaped hole, and the positioning plate 41 is connected to the frame of the belt conveyor 1 by the bolt. By providing a waist-shaped hole on the positioning plate 41, this application allows the positioning plate to be adjusted in the Y direction to make the skirt anti-accumulation device suitable for different installation positions of the skirt conveyor belt 12 on the belt conveyor 1 and other working conditions.
[0063] In some embodiments, a polyurethane buffer pad is attached to the lower surface of the positioning plate 41. Since the push plate 2 will generate a certain impact force on the positioning plate 41 during the movement between the first position and the second position, this application reduces the friction and noise between the positioning plate 41 and the belt conveyor 1 by setting a polyurethane buffer pad, thereby improving the service life of the skirt anti-accumulation device.
[0064] It should be noted that in the examples and description of this utility model, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
[0065] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions.
