[0032] The sprocket of the chain conveyor is installed on the frame through the above-mentioned sprocket installation structure, wherein the fixed frame is fixedly connected to the frame.
[0033] Furthermore, in order to better implement the present utility model, the fixed frame is welded on the outer side wall of the frame so that the sliding part and the bearings in the sliding part are both located outside the frame.
[0034] The present utility model has the following beneficial effects compared with the prior art:
[0035] (1) The sprocket installation structure of the chain conveyor provided by the present utility model includes a rotating shaft, a sliding part, a fixed frame, a fixing plate and an elastic member. The sprocket of the chain conveyor is installed in the middle of the rotating shaft. Bearings are installed at the ends of the rotating shaft. The sliding part is provided with a circular through hole, and the bearings are installed in the circular through hole. The fixed frame is provided with a track, and the sliding part is slidably installed on the track. The fixed frame is provided with a long through hole, and the length direction of the long through hole is parallel to the sliding direction of the sliding part. The rotating shaft is slidably inserted into the long through hole. The fixing plate is fixedly installed on the fixed frame, and the elastic member is installed between the sliding part and the fixing plate to elastically connect the sliding part and the fixing plate.
[0036] When the chain of the chain conveyor becomes loose or is dragged by an external force (the resistance exerted by the conveyed material on the belt or the material deflecting plate), the external force is transmitted to the rotating shaft through the sprocket, thereby driving the slider to slide on the above-mentioned track, so that the elastic member accumulates elastic potential energy. When the above external force disappears, if the position of the rotating shaft cannot be reset, the chain will become loose. In the installation structure provided by the present utility model, due to the provision of the above elastic member, when the external force disappears, the elastic force of the elastic member will drive the rotating shaft to reset, thereby tightening the chain. Therefore, through the above installation structure, the rotating shaft can adaptively move its position so that the chain can adaptively adjust its tightness. When the external force disappears, the chain can be automatically tightened.
[0037] (2) The manure spreader provided by the present utility model includes a vehicle frame, a hopper, a manure throwing disc, a chain conveyor, and the above-mentioned sprocket installation structure. The vehicle frame is equipped with rollers or crawlers for the manure spreader to travel. The hopper is installed on the vehicle frame and is used to hold manure. An outlet is provided on the bottom side wall of the hopper. The manure throwing disc is rotatably installed on the vehicle frame, located below the outlet, and is driven to rotate by a driving mechanism to throw the manure falling on it outward. The chain conveyor is configured with a chain and manure pushing blocks installed on the chain. The chain is wound around the sprocket. When the chain conveyor is operating (the chain conveyor also includes an electric motor for driving the operation of the chain conveyor), the chain drives the manure pushing blocks to rotate at the bottom of the hopper to push the manure at the bottom of the hopper to the outlet. The sprocket of the chain conveyor is installed on the vehicle frame through the above-mentioned sprocket installation structure, wherein the fixed frame is fixedly connected to the vehicle frame.
[0038] In this way, when the manure pushing blocks of the chain conveyor rotate with the chain, they can provide greater force to push the manure in the hopper to the outlet. With the help of the above-mentioned sprocket installation structure, the chain of the chain conveyor used in this manure spreader can be adjusted adaptively in terms of tightness.

Detailed implementation mode
[0047] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.
[0048] Embodiment 1:
[0049] The sprocket installation structure of the chain conveyor provided by the present utility model is as shown in Figure 3 and Figure 4 wherein Figure 3 shows the structural schematic diagram of the sprocket installation structure provided by the present utility model, Figure 4 and
[0050] shows the exploded view of the sprocket installation structure. Specifically, the sprocket installation structure includes a rotating shaft 100, a sliding part 300, a fixed frame 400, a fixed plate 600 and an elastic member, wherein: The sprocket 910 of the chain conveyor is installed in the middle of the rotating shaft 100. A bearing 200 is installed at the end of the rotating shaft 100. The sliding part 300 is provided with a circular through - hole, and the bearing 200 is installed in the circular through - hole. At this time, the slide block 310 can be understood as a mounting seat for installing the bearing 200. The fixed frame 400 is installed with a track 500, and the sliding part 300 is slidably installed on the track 500. The fixed frame 400 is provided with a long through - hole 410, and the length direction of the long through - hole 410 is parallel to the sliding direction of the sliding part 300. The rotating shaft 100 is slidably inserted into the long through - hole 410. In this way, the rotating shaft 100 can slide along the length direction of the long through - hole 410 in the long through - hole 410. The fixed plate 600 is fixedly installed on the fixed frame 400, and the elastic member is installed between the sliding part 300 and the fixed plate 600 to elastically connect the sliding part 300 and the fixed plate 600.
[0051] When the chain 900 of the chain conveyor becomes loose or is dragged by an external force (the resistance exerted by the conveyed material on the belt or the material stripping plate), the external force is transmitted to the rotating shaft 100 through the sprocket 910, thereby driving the slider 310 to slide on the above-mentioned track 500, so that the elastic member accumulates elastic potential energy. When the above-mentioned external force disappears, if the position of the rotating shaft 100 cannot be reset, the chain 900 will become loose. In the installation structure provided by the utility model, since the above-mentioned elastic member is provided, when the external force disappears, the elastic force of the elastic member will drive the rotating shaft 100 to reset, and then tighten the chain 900. Therefore, through the above-mentioned installation structure, the rotating shaft 100 can be adaptively moved to allow the chain 900 to be adaptively loosened or tightened. When the external force disappears, the chain 900 can be automatically tightened.
[0052] Optionally, the sliding portion 300 includes a slider 310 and a connecting rod, the slider 310 is slidably matched with the track 500, the circular through hole for installing the bearing 200 is opened on the slider 310, one end of the connecting rod is detachably fixedly connected to the slider 310, a through hole is opened in the fixed plate 600, the connecting rod is slidably inserted in the through hole, and a resisting portion 330 is detachably fixedly installed in the middle of the connecting rod, and the resisting portion 330 is located between the slider 310 and the fixed plate 600. The elastic member in this embodiment is a spring 700, which is sleeved outside the connecting rod, and the two ends of the spring 700 are respectively abutted against the resisting portion 330 and the fixed plate 600.
[0053] In this way, when the chain 900 is loose or tight, the slider 310 will be driven to slide on the track 500, thereby causing the connecting rod to move toward the side of the fixed plate 600, and the above-mentioned resisting portion 330 will also move toward the fixed plate 600, thereby squeezing the spring 700. When the external force disappears, the compressed spring 700 pushes the resisting portion 330, causing the connecting rod and the slider 310 to move toward the side away from the fixed plate 600 and automatically reset.
[0054] Specifically, Figure 5 As shown, a connecting frame 311 is provided on one side of the slider 310, and the connecting rod is a screw rod 320. One end of the screw rod 320 passes through the connecting frame 311 and is inserted into the interior of the connecting frame 311. Two first nuts 340 are screwed on the screw rod 320. The two first nuts 340 are respectively located on the inner side and the outer side of the connecting frame 311. When the two first nuts 340 are tightened on the screw rod 320, the two first nuts 340 lock the screw rod 320 to the connecting frame 311, thereby detachably and fixedly connecting one end of the connecting rod to the slider 310.
[0055] The above-mentioned resisting portion 330 includes a second nut 331 and a gasket 332. The second nut 331 is screwed onto the screw rod 320. The gasket 332 is sleeved on the screw rod 320, and the gasket 332 is located between the second nut 331 and the fixing plate 600. The spring 700 abuts against the gasket 332. Of course, one end of the spring 700 can also be fixedly welded to the gasket 332, and the other end of the spring 700 is fixedly welded to the fixing plate 600.
[0056] An alternative implementation of this embodiment is as follows: The above-mentioned track 500 includes an upper block 510 and a lower block 520. The upper block 510 is fixedly welded to the fixing frame 400. A first sliding groove is provided on the bottom surface of the upper block 510. The lower block 520 is fixedly welded to the fixing frame 400. The upper block 510 and the lower block 520 are vertically aligned. A second sliding groove is provided on the top surface of the lower block 520. The top end and the bottom end of the slider 310 are respectively slidably placed in the first sliding groove and the second sliding groove. In this way, the slider 310 is slidably installed between the upper block 510 and the lower block 520.
[0057] In order to make the fixing plate 600 more stably connected to the fixing frame 400, in this embodiment, a wing plate 610 is fixedly provided on the fixing plate 600. Specifically, the wing plate 610 is integrally formed with the fixing plate 600. The wing plate 610 and the fixing plate 600 are both fixedly welded to the fixing frame 400. In this way, not only the welding area is increased, but also the structural strength of the fixing plate 600 can be increased.
[0058] Embodiment 2:
[0059] The manure spreader provided in this embodiment is as Figure 1 and Figure 2 shown, and it includes a vehicle frame 800, a hopper 820, a manure spreading disc 830, a chain conveyor, and the above-mentioned sprocket mounting structure, wherein:
[0060] The vehicle frame 800 is equipped with rollers or crawlers 810 for the manure spreader to travel. The hopper 820 is installed on the vehicle frame 800. The hopper 820 is used to hold manure. A discharge port is provided on the bottom side wall of the hopper 820. The manure spreading disc 830 is rotatably installed on the vehicle frame 800. The manure spreading disc 830 is located below the discharge port and is driven to rotate by a driving mechanism to throw the manure falling on it outward. The chain conveyor is provided with a chain 900 and a manure pushing block 920 installed on the chain 900. The chain 900 is wound around a sprocket 910. When the chain conveyor operates (the chain conveyor also includes an electric motor for driving the chain conveyor to operate), the chain 900 drives the manure pushing block 920 to rotate at the bottom of the hopper 820 to push the manure at the bottom of the hopper 820 to the discharge port. The sprocket 910 of the chain conveyor is installed on the vehicle frame 800 through the above-mentioned sprocket mounting structure, wherein the fixing frame 400 is fixedly connected to the vehicle frame 800.
[0061] It should be noted that the sprockets 910 of the chain conveyor are divided into a driving sprocket and a driven sprocket. The rotating shaft for installing the driving sprocket is fixed on the vehicle frame 800, and the rotating shaft 100 for installing the driven sprocket is slidably installed on the vehicle frame 800 through the sprocket installation structure provided by the embodiment.
[0062] In this way, when the dung pushing block 920 of the chain conveyor rotates with the chain 900, it can provide a greater force to push the dung in the hopper 820 to the discharge port. With the above sprocket installation structure, the chain 900 of the chain conveyor used in this manure spreader can be adjusted adaptively in terms of tightness.
[0063] More preferably, the fixing frame 400 is welded to the outer side wall of the vehicle frame 800, so that the sliding part 300 and the bearing 200 in the sliding part 300 are both located outside the vehicle frame 800. This makes it more convenient to replace and maintain the bearing 200.
[0064] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
