Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, and particularly relates to a kitchen waste shredder. Background Art

[0002] Kitchen waste refers to the waste generated in residents' daily life, food processing, catering services, unit meal supply and other activities. For example, the roots, stems, leaves, flowers, fruits, seeds of plants, the skin, muscles, bones, internal organs of animals, the mycelium and fruiting bodies of fungi, etc. A large amount of kitchen waste will be generated in human life. However, kitchen waste has a high water content and is prone to rot and produce odors in daily life, polluting the environment. Therefore, we can put the kitchen waste into a fermentation tank to ferment it into organic fertilizer.

[0003] Existing kitchen waste treatment devices generally only recycle kitchen waste as a whole or cut kitchen waste manually; however, when directly landfilled without treatment, the volume is large and the fermentation time is long; when manually cutting, it is easy to get injured, and the manual cutting speed is slow, which requires a lot of time and human resources. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a kitchen waste shredder, which overcomes the deficiencies of the prior art, is reasonably designed, and can effectively pull, cut and break kitchen waste, thus greatly improving the crushing efficiency of kitchen waste.

[0005] To achieve the above object, the utility model is realized through the following technical solutions:

[0006] A kitchen waste shredder includes a shredding box body with an open upper end. An outlet is arranged at the lower end of the shredding box body. A first rotating shaft and a second rotating shaft which are parallel to each other are horizontally installed in the middle of the shredding box body through bearing seats. One end of the first rotating shaft passes through one side surface of the shredding box body and is fixedly connected with a driving gear. One end of the second rotating shaft passes through one side surface of the shredding box body and is fixedly connected with a driven gear. The driving gear and the driven gear are meshed with each other. The other end of the first rotating shaft passes through the other side surface of the shredding box body and is in transmission connection with the driving shaft of a driving motor;

[0007] A plurality of first large gears and a plurality of first small gears are alternately installed on the outer surface of the first rotating shaft. A plurality of second large gears and a plurality of second small gears are alternately installed on the outer surface of the second rotating shaft. The outer tooth ring of the first large gear is matched with the outer tooth ring of the second small gear. The outer tooth ring of the first small gear is matched with the outer tooth ring of the second large gear; there is a certain distance between the outer tooth ring of the first large gear and the outer tooth ring of the second small gear, and there is a certain distance between the outer tooth ring of the first small gear and the outer tooth ring of the second large gear.

[0008] Preferably, a plurality of first mounting sleeves are sleeved on the outer surface of the first rotating shaft, and a first large gear and a first small gear are respectively mounted on each first mounting sleeve; a plurality of second mounting sleeves are sleeved on the outer surface of the second rotating shaft, and a second large gear and a second small gear are respectively mounted on each second mounting sleeve.

[0009] Preferably, cutting notches are symmetrically formed on the circumferential surfaces of the first large gear and the second large gear.

[0010] Preferably, a feeding fence is fixedly mounted at the upper end of the shredding box body. One side of the feeding fence is open, and a guiding inclined plane block is mounted on the open side of the feeding fence.

[0011] Preferably, the shredding box body is arranged in a conical structure.

[0012] The utility model provides a kitchen waste shredder, which has the following beneficial effects: through the meshing of the driving gear and the driven gear, the first rotating shaft and the second rotating shaft can be driven to rotate synchronously in opposite directions, and then the outer tooth ring of the first large gear is engaged with the outer tooth ring of the second small gear, and the outer tooth ring of the first small gear is engaged with the outer tooth ring of the second large gear. The kitchen waste is sheared and crushed through the cooperative shearing action of each first large gear and each second small gear, and the cooperative shearing action of each first small gear and each second large gear, so as to realize the shearing and crushing treatment of the kitchen waste. And because the first rotating shaft and the second rotating shaft rotate synchronously through the meshing of the driving gear and the driven gear, the unity of the rotation speeds of the first rotating shaft and the second rotating shaft can be ensured. The sheared and crushed kitchen waste can be output through the discharge port at the lower end of the shredding box body. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0021] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model.

[0022] Example 1, as Figures 1-5 shown, a kitchen waste shredder includes a shredding box body 1 with an open upper end. A discharge port 2 is arranged at the lower end of the shredding box body 1. A first rotating shaft 3 and a second rotating shaft 4 which are parallel to each other are horizontally installed in the middle of the shredding box body 1 through a bearing seat 18. One end of the first rotating shaft 3 passes through one side surface of the shredding box body 1 and is fixedly connected with a driving gear 5. One end of the second rotating shaft 4 passes through one side surface of the shredding box body 1 and is fixedly connected with a driven gear 6. The driving gear 5 and the driven gear 6 are meshed with each other. The other end of the first rotating shaft 3 passes through the other side surface of the shredding box body 1 and is in transmission connection with the driving end of a driving motor 7;

The outer tooth ring of the first large gear 8 is matched with the outer tooth ring of the second small gear 11. The outer tooth ring of the first small gear 9 is matched with the outer tooth ring of the second large gear 10; There is a certain distance between the outer tooth ring of the first large gear 8 and the outer tooth ring of the second small gear 11. There is a certain distance between the outer tooth ring of the first small gear 9 and the outer tooth ring of the second large gear 10.

[0024] Working principle:

[0025] When in use, first start the driving motor 7 to drive the first rotating shaft 3 to rotate through the driving end of the driving motor 7, and then drive the first rotating shaft 3 and the second rotating shaft 4 to rotate synchronously in opposite directions through the meshing of the driving gear 5 and the driven gear 6, so that the outer tooth ring of the first large gear 8 is matched with the outer tooth ring of the second small gear 11 to rotate, and the outer tooth ring of the first small gear 9 is matched with the outer tooth ring of the second large gear 10 to rotate.

[0026] Afterwards, the kitchen waste can be directly poured into the shredding box body 1, so that the kitchen waste is sheared and crushed through the cooperative shearing action of each first large gear 8 and each second small gear 11, and the cooperative shearing action of each first small gear 9 and each second large gear 10. And because the first rotating shaft 3 and the second rotating shaft 4 rotate synchronously through the meshing action of the driving gear 5 and the driven gear 6, the unity of the rotation speeds of the first rotating shaft 3 and the second rotating shaft 4 can be ensured. Subsequently, the crushing efficiency can be greatly improved. The sheared and crushed kitchen waste can be output through the discharge port 2 at the lower end of the shredding box body 1.

[0028] Therefore, during assembly, the appropriate number of first mounting sleeves 12 and second mounting sleeves 13 can be selected according to needs. Then, the first mounting sleeves 12 and the second mounting sleeves 13 are respectively sleeved on the first rotating shaft 3 and the second rotating shaft 4 at equal intervals, and then the first mounting sleeves 12 and the second mounting sleeves 13 are locked by locking bolts, so as to complete the installation and fixation work of the first large gear 8, the first small gear 9, the second large gear 10 and the second small gear 11; and the relative distances between the first mounting sleeves 12 and the second mounting sleeves 13 can also be adjusted adaptively according to actual needs.

[0029] Embodiment 3, as a further preferred solution of Embodiment 1, cutting slots 15 are symmetrically arranged on the circumferential surfaces of the first large gear 8 and the second large gear 10. By providing the cutting slots 15, impact crushing treatment can be carried out on larger pieces of garbage.
