Description
Technical Field
[0001] This utility model relates to the field of solid waste crushing equipment, and in particular to a pusher mounting structure and a crusher using the pusher mounting structure. Background Technology
[0002] With social development and continuous advancements in science and technology, the amount of solid waste generated in daily life and production is increasing. To recycle this valuable solid waste, specialized crushers for crushing solid waste have emerged on the market. These crushers generally include a crusher housing, inside which is a crushing chamber. A crushing main shaft for crushing solid waste is rotatably mounted within the crushing chamber. A drive motor is installed in the crusher housing and is connected to the crushing main shaft. A pusher is also installed inside the crushing chamber to move the solid waste closer to the crushing main shaft. When solid waste is placed into the crushing chamber, the drive motor drives the crushing main shaft to rotate, and the pusher pushes the solid waste closer to the crushing main shaft, at which point the crushing main shaft can crush the solid waste.
[0003] While the aforementioned crusher can meet the requirements for crushing solid waste, the existing crusher pusher generally adopts the following installation structure: Each end of the pusher has an inner swing rod, and rotating holes are coaxially opened on opposite side walls of the crushing chamber. A rotating shaft is installed at the end of each of the two inner swing rods, and the two rotating shafts are correspondingly installed inside the two rotating holes. The other ends of the two rotating shafts are connected to outer swing rods, and each of the two outer swing rods is connected to a hydraulic cylinder. The two hydraulic cylinders are respectively installed on opposite sides of the crusher housing. When the pusher needs to move solid waste, the two hydraulic cylinders drive the two outer swing rods, which in turn drive the two rotating shafts to rotate. The two rotating shafts, through the two inner swing rods, drive the pusher to move the solid waste closer to the crushing main shaft. Although the above-mentioned pusher can meet the requirement of the crusher to move solid waste closer to the crushing main shaft, enterprises need to open two coaxially arranged rotating holes on opposite side inner walls of the crushing chamber. Therefore, the processing precision requirements for the crusher housing are very high, the processing difficulty is large, and the production cost of the crusher is high. Utility Model Content

To this end, this invention provides a pusher mounting structure, which helps to reduce the machining accuracy requirements of the crusher shell and facilitates the installation of the pusher; this invention also provides a crusher using the above-mentioned pusher mounting structure, which helps to reduce the production cost of the crusher.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0031] Figures 1 to 7 This is a schematic diagram of some embodiments of the pusher mounting structure of this utility model.
[0032] Reference Figures 1 to 7 and mainly refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 According to certain embodiments of the present invention, a pusher mounting structure is provided. For ease of explanation, it will sometimes be referred to simply as a "pusher mounting structure". The pusher mounting structure includes a crusher housing 100 and a pusher assembly 200. In this embodiment, a crushing chamber 110 is provided inside the crusher housing 100. The upper part of the crushing chamber 110 is open. The tops of the two opposite side walls of the crushing chamber 110 are respectively provided with mounting grooves 120. Both mounting grooves 120 are connected to the crushing chamber 110. In this embodiment, the mounting grooves 120 are openings that extend downward from the top of the side wall of the crushing chamber 110 to the interior of the side wall. The pusher assembly 200 includes a pusher body 210 and two sets of connecting mechanisms 220. The two sets of connecting mechanisms 220 are correspondingly arranged at both ends of the pusher body 210. Each set of connecting mechanisms 220 includes a base 221, a first swing rod 222, a rotating shaft 223, and a second swing rod 224. The rotating shaft 223 is rotatably mounted on the base 221. One end of the first swing rod 222 is connected to the rotating shaft 223, and the other end of the first swing rod 222 is connected to the pusher body 210. One end of the second swing rod 224 is connected to the rotating shaft 223. When the pusher assembly 200 is installed in the crusher housing 100, the pusher body 210 and the two first swing rods 222 are located inside the crushing chamber 110, and the two bases 221 are correspondingly installed in the two mounting slots 120.
[0033] In this embodiment, mounting slots 120 are respectively provided on the top of the two opposite side walls of the crushing chamber 110. A set of connecting mechanisms 220 is provided at both ends of the pusher body 210 of the pusher assembly 200. Each set of connecting mechanisms 220 includes a base 221, a first swing arm 222, a rotating shaft 223, and a second swing arm 224. The rotating shaft 223 is rotatably mounted on the base 221. The two ends of the first swing arm 222 are connected one-to-one with the rotating shaft 223 and the pusher body 210. During production, the enterprise can first assemble the two sets of connecting mechanisms 220 and the pusher body 210 to form the pusher assembly 200, and then the enterprise can then... The pusher body 210 and the two first swing rods 222 of the feeder assembly 200 move from top to bottom and embed into the crushing chamber 110, so that the two bases 221 are fitted into the two mounting slots 120 one by one. Then, the two bases 221 are locked into the corresponding mounting slots 120, thus completing the assembly of the pusher assembly 200 and the crusher housing 100. The assembly is simpler and faster, and the enterprise does not need to process two coaxial rotating holes on the two opposite side walls of the crushing chamber 110. Therefore, it can greatly reduce the processing precision required of the crusher housing 100, reduce the processing difficulty, and help improve the enterprise's production efficiency.
[0034] In some embodiments of this utility model, a mounting hole 2210 is provided inside the base 221, and the rotating shaft 223 is rotatably mounted in the mounting hole 2210. Furthermore, a bearing 225 is provided inside the mounting hole 2210 and sleeved on the outer periphery of the rotating shaft 223. By installing the bearing 225 for supporting the rotating shaft 223 inside the base 221, the rotation of the rotating shaft 223 relative to the base 221 can be made smoother, and the rotating shaft 223 and the base 221 are less prone to wear during repeated relative rotation.
[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments of this utility model, the pusher assembly 200 includes two sets of drive mechanisms 230, which are connected to two second rocker arms 224 in a one-to-one transmission manner. The two sets of drive mechanisms 230 are respectively disposed on two opposite side walls of the crushing chamber 110. By adopting the above structure, the two sets of drive mechanisms 230 can drive the corresponding rotating shafts 223 to rotate through the corresponding second rocker arms 224. Then, the two rotating shafts 223 drive the pusher body 210 to swing relative to the crusher housing 100 through the first rocker arms 222, thereby enabling the pusher body 210 to push the material placed inside the crushing chamber 110 to move.
[0036] In some embodiments of this invention, the ends of the two second rocker arms 224 furthest from the rotating shaft 223 are both connecting ends, and the connecting ends of the two second rocker arms 224 extend upward to the outside of the mounting groove 120. Two sets of drive mechanisms 230 are correspondingly installed on the tops of the two opposite side walls of the crushing chamber 110, and the two sets of drive mechanisms 230 are connected to the connecting ends of the two second rocker arms 224 in a corresponding transmission connection. By adopting the above structure, the assembly of the drive mechanism 230, the second rocker arms 224, and the crusher housing 100 can be simplified.
[0037] To enable the two sets of drive mechanisms 230 to better drive the pusher body 210 to swing relative to the crusher housing 100, in some embodiments of this invention, each set of drive mechanisms 230 includes a hydraulic cylinder movably mounted on the top of the side wall of the crushing chamber 110, with the piston rod of the hydraulic cylinder rotatably connected to the connecting end of the corresponding second swing arm 224. Furthermore, each set of drive mechanisms 230 includes a mounting base 231, which is fixedly mounted on the top of the side wall of the crushing chamber 110, and the drive mechanism 230 is rotatably mounted on the mounting base 231. By adopting the above structure, the two sets of drive mechanisms 230 can apply greater thrust to the two second swing arms 224 respectively, thus driving the pusher body 210 to swing relative to the crusher housing 100 via the corresponding rotating shaft 223 and the first swing arm 222.
[0038] It should be noted that in the above embodiments, the drive mechanism 230 is a hydraulic cylinder, while in other embodiments of this utility model, the drive mechanism 230 can also be set as a pneumatic cylinder or an electric push rod, depending on the actual needs.
[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7To ensure a more secure installation of the base 221 into the mounting groove 120, in some embodiments of this invention, mounting plates 121 are provided on the inner walls of opposite sides of the mounting groove 120. A notch 122, capable of accommodating the rotating shaft 223, is provided between the two mounting plates 121. Connecting plates 2211 are provided on opposite sides of the base 221. When the base 221 is installed in the mounting groove 120, the two connecting plates 2211 are connected to the two mounting plates 121 in a one-to-one correspondence. With this structure, after the base 221 is embedded in the mounting groove 120, workers can use bolts to lock one connecting plate 2211 to one mounting plate 121, and use bolts to lock the other connecting plate 2211 to the other mounting plate 121. Therefore, the base 221 can be securely installed in the corresponding mounting groove 120, making assembly more convenient. In this utility model, the mounting plate 121 has an elliptical groove. Therefore, when the worker uses bolts to connect the connecting plate 2211 of the base 221 to the mounting plate 121, the user can adjust the position of the bolts through the groove, thereby adjusting the position of the base 221 installed in the mounting groove 120. This achieves fine adjustment of the mounting device of the base 221 and further reduces the difficulty of installing the base 221 in the mounting groove 120.
[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments of this utility model, the crushing chamber 110 has an arc-shaped inner wall, and a paddle 211 is provided on one side of the pusher body 210. The paddle 211 is provided with a plurality of protrusions 212 that can contact the arc-shaped inner wall, and the plurality of protrusions 212 are arranged evenly at intervals along the length direction of the paddle 211. By adopting the above structure, when the two sets of drive mechanisms 230 drive the pusher body 210 to swing relative to the crusher housing 100 through the connecting mechanism 220, the pusher body 210 can better scrape and push the material close to the arc-shaped inner wall of the crushing chamber 110 through the plurality of protrusions 212 of the paddle 211, thereby making the pushing effect of the pusher assembly 200 in this embodiment better.
[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6In some embodiments of this utility model, each first rocker arm 222 has a ramp 2220 for avoiding material at one end connected to the pusher body 210. The ramp 2220 is located on the side of the first rocker arm 222 away from the other first rocker arm 222. By adopting the above structure, a space for avoiding material is formed between the first rocker arm 222 and the inner wall of the crushing chamber 110. Therefore, when the pusher body 210 pushes the material to move inside the crushing chamber 110, the above space can effectively prevent the material from blocking the gap between the pusher body 210 and the crushing chamber 110 and causing the pusher body 210 to get stuck, thereby allowing the pusher body 210 to push the material to move better.
[0042] Reference Figures 1 to 7 This utility model provides a crusher according to certain embodiments, wherein the crusher adopts the above-described pusher mounting structure.
[0043] Because the crusher in this embodiment adopts the above-mentioned pusher installation structure, it can greatly reduce the processing precision required for the crusher shell and reduce the processing difficulty. Moreover, during assembly, the enterprise moves the pusher body 210 and the two first swing rods 222 of the pusher assembly 200 from top to bottom and embeds them into the crushing chamber 110, so that the two bases 221 are correspondingly embedded in the two mounting slots 120. Then, the two bases 221 are locked into the corresponding mounting slots 120, thus completing the assembly of the pusher assembly 200 and the crusher shell 100. The assembly is simpler and faster, which helps to improve the enterprise's production efficiency and reduce the production cost of the crusher.
[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
