Description

Technical Field

[0001] The utility model belongs to the technical field of waste treatment, and particularly relates to a pushing structure and a kitchen waste treatment device including the same. Background Art

[0002] Household kitchen solid-liquid waste refers to a mixture of various food residues generated during daily kitchen cooking and food processing, including plant roots, meat scraps, bones, fruit peels, etc. If these wastes are not properly treated, they will not only bring odors and sanitation problems to the living environment, but also may produce harmful gases and affect the surrounding environment. In order to effectively treat these solid-liquid wastes, people can use a kitchen solid-liquid waste processor to grind them, breaking the wastes into fine particles for subsequent treatment and reuse.

[0003] When treating kitchen solid-liquid waste, the kitchen solid-liquid waste is quickly shredded by a high-speed rotating blade. For a horizontally arranged shredding device, the high-speed rotating blade generates wind force, resulting in the kitchen waste being easily piled up at the front end of the shredding device. The blade cannot fully contact the waste, leading to an unsatisfactory shredding effect. In addition, since the kitchen waste is piled up at the front end of the shredding device, it may also cause the processed material to not be completely collected into the collection device. Summary of the Invention

[0004] To solve the above problems, the present application provides a pushing structure, aiming to move the waste piled up at the front end of the grinding cylinder back into the grinding cylinder through a material sliding channel and a pushing piece, so that the grinding rotating blade can fully contact the waste, improve the shredding efficiency, and enable the shredded processed material to smoothly fall into the collection device through the second channel.

[0030] A grinding cutter 3-1 is rotatably connected inside the grinding cylinder 3 to achieve high-speed grinding with low torque.

[0031] A cylinder cover 6 is arranged at the front end opening of the grinding cylinder 3 to achieve the sealing effect of the grinding cylinder 3 and prevent waste from leaking out.

[0032] A sliding material channel 6-1 is formed by the rear side of the cylinder cover 6 being recessed inward. The surface of the sliding material channel 6-1 facing the grinding cylinder 3 is arc-shaped and arranged vertically. The upper end surface of the lower part of the arc is inclined towards the side of the grinding cylinder 3 and is smoothly connected to the bottom of the grinding cylinder 3, so that the waste accumulated at the front end of the grinding cylinder 3 due to the wind generated by the high-speed rotating grinding cutter 3-1 slides down along the sliding material channel 6-1 from top to bottom and falls back into the grinding cylinder 3, improving the crushing efficiency and waste collection efficiency.

[0033] A material pushing piece 7 is arranged behind the cylinder cover 6. The material pushing piece 7 can move from front to back inside the grinding cylinder 3, so as to push the waste accumulated at the front end of the grinding cylinder 3 back into the grinding cylinder 3, enabling the grinding cutter 3-1 to fully contact the waste, improving the crushing efficiency, and enabling the processed material after crushing to smoothly fall from the second channel 4 into the collection device 5.

[0034] The cylinder cover 6 is a hollow cavity. A driving component for driving the material pushing piece 7 is arranged inside the cavity of the cylinder cover 6. The driving component includes a motor 8, a gear 9, and a sliding rack 10. One end of the sliding rack 10 is meshed and connected below the gear 9, and the other end is connected to the material pushing piece 7. The motor 8 drives the sliding rack 10 to move through the gear 9, thereby realizing the movement of the material pushing piece 7.

[0035] In order to maintain the overall balance effect, a balance rod 11 parallel to the sliding rack 10 is also connected to the material pushing piece 7. The balance rod 11 does not participate in the transmission effect and is only used for balance.

[0036] Two positioning holes 6-2 are opened on the wall surface at the rear side of the cylinder cover 6. The front end of the sliding rack 10 is set in a toothed shape meshed with the gear 9, and the rear end is set in a rod shape adapted to the positioning holes 6-2. The balance rod 11 is set in a rod shape adapted to the positioning holes 6-2. The balance rod 11 and the sliding rack 10 respectively pass through a positioning hole 6-2 and can move back and forth in the positioning holes 6-2.

[0037] A fixed bracket 12 is provided below the sliding rack 10. A contact switch 13 is installed on the fixed bracket 12, and the position information of the pusher 7 is obtained through the contact switch 13. When the sliding rack 10 moves towards the grinding cylinder 3, the contact switch 13 can abut against the positioning hole 6-2, thereby obtaining the current position information.
