[0002] In the process of recycling and disposing of waste oil barrels, they first need to be shredded. The recycled waste oil barrels are conveyed to the shredder through a conveyor belt. The waste oil barrels will fall directly from a high place into the shredder. However, the shredder's blades are hard and brittle. Due to the frequent impact of the waste oil barrels, it is very easy to cause the blades of the blades to break. The prior art with announcement number CN218796443U discloses a shredder with a buffering function, which is provided at the inlet with two buffer plates inclined from top to bottom toward the central axis of the box body. One end of the buffer plate is hinged to the inner wall of the box body, and is connected to the mounting plate through a connecting assembly to buffer the falling material blocks. However, the weight of a single waste oil barrel is as high as about 20 kilograms, and the above-mentioned buffer structure is still difficult to withstand the impact of its fall, resulting in damage to the connecting assembly and poor buffering effect.

[0026] like Figures 1 to 6 As shown, the utility model provides a shredder buffer feeding mechanism, including a shredder body 10, a buffer support seat 20 is provided on one side of the feed inlet of the shredder body 10, an elastic barrel member 30 is movably mounted on the buffer support seat 20, and a push barrel assembly 40 is provided on one end of the buffer support seat 20 away from the feed inlet of the shredder body 10, and the driving end of the push barrel assembly 40 can extend toward the feed inlet of the shredder body 10. The shredder body 10 is a prior art and will not be described in detail in this application; the position setting of the buffer feeding mechanism of this invention can refer to Figure 2The output end of the conveyor belt for transporting the waste oil barrel is located on one side above the hopper of the shredder body 10, and the elastic barrel support 30 is located below the output end of the conveyor belt and between the feed inlet of the shredder body 10 to receive and buffer the falling waste oil barrel. In addition, the buffer support seat 20 and the elastic barrel support 30 can also be tilted toward the feed inlet. When the waste oil barrel falls to the elastic barrel support 30 and is buffered, it can continue to slide into the cutter for crushing.

[0027] See also Figures 3 to 6 In a specific embodiment of the present application, the buffer support seat 20 includes a support frame 21 installed on one side of the feed inlet of the shredder body 10, an arc-shaped support plate 22 is provided on the upper end of the support frame 21, the elastic barrel member 30 is movably installed on the arc-shaped support plate 22, and the barrel pusher assembly 40 is installed on the end of the support frame 21 away from the feed inlet of the shredder body 10. The support frame 21 includes support legs on both sides and a support plate at the bottom, which can stably support the elastic barrel member 30 and is not easy to be damaged.

[0028] Specifically, the elastic barrel support member 30 includes an arc-shaped barrel support plate 31 and a return spring 32. The return spring 32 is arranged on the arc-shaped support plate 22, and the arc-shaped barrel support plate 31 is arranged on the upper end of the return spring 32. The arc-shaped barrel support plate 31 is an arc-shaped structure that can match the shape of the waste oil barrel to increase the contact area with the waste oil barrel and enhance the buffering effect. When the waste oil barrel falls onto the arc-shaped barrel support plate 31, the return spring 32 will be compressed, and the arc-shaped barrel support plate 31 will move down to buffer the waste oil barrel; after the waste oil barrel enters the feed port, the return spring 32 can be reset to make the arc-shaped barrel support plate 31 move up. Furthermore, in order to prevent the arc-shaped barrel-bearing plate 31 from shaking left and right when the waste oil barrel falls, the elastic barrel-bearing member 30 also includes a limiting plug rod 33. The arc-shaped support plate 22 is provided with a limiting hole 23. The limiting plug rod 33 is movably inserted in the limiting hole 23. The arc-shaped barrel-bearing plate 32 is arranged on the upper end of the plug rod 31. It is ensured that the arc-shaped barrel-bearing plate 31 moves up and down under the limitation of the limiting plug rod 33 and the limiting hole 23. In addition, a supporting plate 34 is provided on the lower end of the limiting plug rod 33. When the waste oil barrel falls and the limiting plug rod 33 moves downward, the supporting plate 34 will be able to resist the supporting frame 21 including the supporting plate at the bottom, further improving the effect of stable support.

[0029] In a specific embodiment of the present application, if the buffer support seat 20 and the elastic barrel support member 30 are tilted toward the feeding port, the waste oil barrel can continue to fall smoothly into the feeding port after buffering, but when it is horizontally arranged, the waste oil barrel may stagnate on the elastic barrel support member 30. Therefore, the barrel push assembly 40 includes a telescopic cylinder 41 and a push plate 42. A vertical baffle 24 is provided on one end of the support frame 21 away from the feeding port of the shredder body 10. A mounting plate 25 is provided on the outer side of the vertical baffle 24. The telescopic cylinder 41 is provided on the mounting plate 25, and the driving end can extend above the arc-shaped barrel support plate 31. The push plate 42 is provided on the driving end of the telescopic cylinder 41. The telescopic cylinder 41 can drive the push plate 42 to push the waste oil barrel on the elastic barrel support 30 to the feed inlet; after the waste oil barrel enters the feed inlet, the arc-shaped barrel support plate 31 will reset upwards without the downward pressure of gravity, so in order to ensure that the telescopic cylinder 41 can be smoothly retracted, the telescopic cylinder 41 is set at a position higher than the elastic barrel support 30 in the unpressed state. In addition, in order to prevent the waste oil barrel from accidentally hitting the push barrel assembly 40, a baffle 26 inclined toward the side of the elastic barrel support 30 is provided on the upper end of the vertical baffle 24, which also has the function of guiding the waste oil barrel.

[0030] Furthermore, to ensure that the waste oil barrel rolls and falls smoothly, a downwardly bent guide plate 27 is provided on one side of the arc-shaped support plate 22 close to the feed inlet of the shredder body 10 to guide the waste oil barrel. In addition, the edge of the arc-shaped barrel support plate 31 close to the feed inlet of the shredder body 10 is arranged in an arc surface to prevent the waste oil barrel from being blocked.

[0031] The utility model discloses a buffer feeding mechanism for a shredder. The mechanism is provided with an elastic barrel member 30 on one side of the feeding port of the shredder body 10, and a buffer support seat 20 is used to support the elastic barrel member 30. With the stable support of the buffer support seat 20, the elastic barrel member 30 can withstand the impact force of the waste oil barrel falling. The waste oil barrel falling from the conveyor belt will fall onto the elastic barrel member 30 and will fall onto the cutter after being buffered. If the waste oil barrel stays on the elastic barrel member 20, it can also be pushed toward the cutter by the barrel pusher assembly 40 to prevent the waste oil barrel from directly hitting the cutter, thereby effectively extending the life of the cutter of the shredder.

[0032] The above embodiments are only used to illustrate the technical solution of the utility model but not to limit it. Any modification or equivalent substitution that does not deviate from the spirit and scope of the utility model shall be included in the scope of the technical solution of the utility model.
