[0006] By adopting the above technical scheme, when the falling material in the chute body needs to be discharged, the hydraulic cylinder is started to drive the support plate to overturn, and under the action of gravity, the falling material in the chute body will automatically slide down, thereby realizing the effect of automatically cleaning the chute body, effectively solving the problem of the short head and scraps accumulated in the chute body, saving manpower and reducing the unplanned downtime.

[0007] Preferably, a chute U-shaped bottom plate is arranged at the bottom of the chute body.

[0008] By adopting the above technical scheme, the flow of the falling material in the chute body can be effectively improved.

[0009] Preferably, the rotation angle of the chute moving plate relative to the chute body is 0-90°.

[0010] By adopting the above technical scheme, when the chute moving plate is opened to 90°, the stubbings in the chute body can be completely released.

[0011] Preferably, the support plate is vertically connected to the center of the bottom wall of the chute moving plate, and the bearing seat is provided with two groups, and the two bearing seats are symmetrically arranged about the support plate.

[0016] By adopting the above technical scheme, the length of the chute moving plate being longer than the length of the opening end of the chute body can prevent the stubbings in the chute body from falling from above the chute moving plate, thereby effectively improving the capacity of the chute body.

[0017] Preferably, the chute moving plate and the chute body are abutted at the abutment.

[0018] By adopting the above technical scheme, the abutment of the two can effectively prevent the stubbings and the like from leaking from the gap between the two when the chute moving plate is not opened, thereby preventing the normal operation of other components.

[0019] Preferably, a waste hopper is arranged below the opening of the chute body.

[0020] By adopting the above technical scheme, the waste hopper can collect the stubbings and the like discharged from the chute body, thereby saving the time for subsequent manual cleaning, and preventing the stubbings and the like from being randomly scattered, thereby preventing the working environment in the workshop from being affected.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 1. When the need to discharge the material in the chute body, by starting the hydraulic cylinder, the support plate is turned over by the hydraulic cylinder, due to the inclined setting of the chute body, under the action of gravity, the material in the chute body will automatically slide, thereby realizing the effect of automatic cleaning of the chute body, effectively solving the problem of short head, scrap accumulation in the chute body, saving manpower, reducing unplanned downtime;

[0023] 2. The chute U-shaped bottom plate arranged in the chute body can effectively improve the flow of the material in the chute body;

[0024] 3. When replacing the waste hopper, the chute moving plate can be closed to eliminate the safety hazard of being injured by the short head cut by the upper part when replacing the waste hopper, improve the work efficiency and safety;

[0025] 4. The length of the chute moving plate is longer than the length of the opening end of the chute body, which can prevent the short head and scrap in the chute body from falling from above the chute moving plate, effectively improve the capacity of the chute body, and the abutting arrangement of the two can effectively prevent the short head and scrap from leaking from the gap between the two when the chute moving plate is not opened, affecting the normal work of other components.
