Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a grid-type conveyor belt drive wheel structure. Background Technology

[0002] A shredder is a mechanical device used to process hard materials such as crop straw, rice straw, and branches into soft filaments. It uses high-speed rotating blades or hammers to rub and chop the materials, breaking down the hard nodes on the surface and making them soft and lump-free, easier for livestock to eat and digest. The shredded straw, impurities, and dust are pushed into the shredder's outlet, and then conveyed by a mechanism into a storage bin for temporary storage.

[0003] Currently, the conveying mechanism of shredders is usually a conveyor belt, which consists of a rubber belt and a cylindrical drive wheel. During the conveying process, a small amount of material falls onto the slack side of the conveyor belt. This material easily moves to the drive wheel on one side. Since the drive wheel is a large cylinder, the material at the drive wheel will only become more compacted and accumulate more and more. Over time, the material accumulated at the drive wheel will completely block the gap between the belt and the main drive wheel, causing the drive wheel to slip and the conveyor belt to malfunction. At this point, the entire machine must be stopped, and the drive wheel of the conveyor belt must be cleaned of dust and weeds. This cleaning operation takes half an hour each time, which seriously affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a grid-type conveyor belt drive wheel structure, which can effectively prevent impurities from accumulating at the drive wheel and causing the belt to slip. It is particularly suitable for use in the conveyor belt mechanism in the straw processing production process.

[0005] The technical solution of this utility model is: a grid-type conveyor belt drive wheel structure, including a central shaft, a flange and grid columns. The flange is sleeved on the central shaft. The flange is circular and coaxial with the central shaft. The grid columns are installed on the outer periphery of the flange, and multiple grid columns are spaced apart on the flange.

[0006] Furthermore, the grid bars are evenly distributed in a circle around the central axis.

[0007] Furthermore, the grid posts remain parallel to the central axis.

[0008] Furthermore, there are multiple flanges; preferably, there are three flanges, which are respectively located in the middle of the central shaft and near the two ends, and the distance between the flanges on both sides is adapted to the length of the grid column.

[0009] Furthermore, it also includes bearings and housings, and each end of the central shaft is provided with a set of bearings and housings, through which the central shaft can rotate freely.

[0010] Furthermore, it also includes an adjusting screw, which is connected to the bearing and the seat, and is used to adjust the horizontal position of the bearing and the seat, thereby adjusting the tension of the belt installed on the drive wheel structure.

[0011] Furthermore, a drive mechanism is provided at the end of the central shaft, under the action of the drive mechanism, the central shaft can rotate.

[0012] Furthermore, the drive mechanism includes sprockets, chains, and motors.

[0013] Furthermore, the diameter of the central shaft in the middle is larger than the diameters at both ends. Preferably, the diameter of the middle section of the central shaft gradually decreases from the middle to both ends, and the total length of the diameter change is adapted to the width of the belt to be installed. During installation, the width of the belt corresponds to the length of the diameter change on the central shaft. In this way, when some material falls onto the central shaft during operation, it will slide along the inclined surface of the central shaft to both sides, causing the material to gradually move towards the two side edges of the belt, preventing the material from accumulating in the middle of the belt. In some embodiments, if the width of the belt is smaller than the length of the diameter change section on the central shaft, the material can also fall directly out from the coverage area of ​​the belt.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The grid-type conveyor belt drive wheel structure in this application can be used in the conveyor belt structure in the straw processing process. Compared with a single cylindrical belt drive wheel, the drive wheel of this application can effectively avoid belt slippage caused by the accumulation of related materials at the drive wheel. This is because the drive wheel of this application is composed of multiple grid bars with smaller diameters and gaps between adjacent grid bars. Even if materials accumulate, they can be discharged from the gaps and will not get stuck in the gap between the belt and the drive wheel. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art.

[0021] Example 1

[0022] like Figure 1-2 As shown, this embodiment provides a grid-type conveyor belt drive wheel structure, including a central shaft 1, a flange 2, and grid posts 3. The flange 2 is sleeved on the central shaft 1. The flange 2 is circular and coaxial with the central shaft 1. The grid posts 3 are fixedly installed on the outer periphery of the flange 2. Multiple grid posts 3 are spaced apart and parallel on the flange 2, and are evenly distributed around the central shaft 1. The grid posts, central shaft, and flange are all made of metal.

[0023] In this embodiment, there are 3 flanges 2, which are respectively located in the middle of the central shaft 1 and near the two ends. The distance between the flanges 2 on both sides is adapted to the length of the grid post 3.

[0024] In this embodiment, the drive wheel structure also includes bearings and seats 4, and a set of bearings and seats 4 is respectively provided at both ends of the central shaft 1, allowing the central shaft 1 to rotate freely. It also includes an adjusting screw 5, which is connected to the bearings and seats 4 and used to adjust the horizontal position of the bearings and seats 4, thereby adjusting the tension of the belt mounted on the drive wheel structure. Using the adjusting screw 5 to adjust the belt tension is existing technology and will not be described in detail here.

[0025] In this embodiment, a drive mechanism is also provided at the end of the central shaft 1, which allows the central shaft 1 to rotate. The drive mechanism in this embodiment includes a sprocket 6, a chain, and a motor. In other embodiments, the drive mechanism may also employ a gear transmission structure or a belt transmission structure, etc.

[0026] In actual use, the belt is fitted onto the two drive wheels in this embodiment, and the tension of the belt is adjusted by adjusting the lead screw 5. The specific usage method and working principle are the same as those of existing conveyor belts. The advantage of this embodiment is that the drive wheel is no longer a single large cylinder, but is composed of multiple small-diameter grid bars 3. The grid bars 3 have a good crushing and separating effect on debris falling at the drive wheel, effectively preventing belt slippage.

[0027] Example 2

[0028] like Figure 3-4As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the central shaft 1 is specially designed so that the diameter of the middle section of the central shaft 1 is larger than the diameters of the two ends. That is, the diameter of the middle section of the central shaft 1 gradually decreases from the middle to both ends; and the length of the diameter change is adapted to the width of the belt to be installed. When installing the belt, the belt is positioned to correspond to the area of ​​diameter change of the central shaft 1. In this way, during the operation of the drive wheel, if some material falls onto the central shaft 1, it will slide along the inclined surface of the central shaft 1 to both sides, causing the material to gradually move towards the two side edges of the belt, preventing the material from accumulating in the middle of the inner side of the belt, and facilitating the sliding of debris from both sides of the belt. Even if the drive wheel is not cleaned for a long time, the belt will not slip.

[0029] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
