Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a kitchen waste crushing device, in particular to a full-automatic garbage disposal crusher and an operation method thereof. Background Art

[0002] The splashing and noise problems during the treatment of food waste have long plagued the garbage disposal industry, so splash prevention and noise reduction are technical difficulties that food waste disposers urgently need to break through. The current common practice is to add a round rubber splash guard to the discharge channel of the garbage disposer.

[0003] This can basically solve the problem of material splashing during the garbage disposal process, but it has little effect on reducing noise. It also brings a problem in use: when pouring food waste into the garbage disposal, you must use your hands or other tools to press the food waste through the splash guard so that the food waste can enter the garbage disposal. This causes your hands or the pressing tools used to be contaminated with a lot of oil and dirt, which needs to be cleaned separately. The inconvenience of pouring food waste and the excessive noise make the user experience extremely poor.

[0004] The crushing structure of the garbage disposer is the core component of the garbage disposer, and plays a decisive role in the processing speed and effect of food waste. However, the types of food waste are relatively complex, with large and small volumes, hard, soft, and tough, so the requirements for the crushing structure are very high.

[0005] Most of the garbage disposers on the market currently use blunt blades and cooperate with surrounding screens to cut. This working principle makes it difficult to handle larger hard bones and high-fiber vegetables, such as turnips, celery and other kitchen waste. It also has low processing efficiency and makes a lot of noise when working. In addition, this type of garbage disposer has low water kinetic energy, which can easily lead to sewer blockage, causing a lot of trouble for users. Summary of the invention

[0011] In the above-mentioned fully automatic garbage disposal shredder, the guide slide groove 1 and the guide slide groove 2 are both straight line grooves, and the straight line grooves extend from the outer circle part to the inner circle part along an inclined straight line trajectory.

[0012] In the above-mentioned fully automatic garbage disposal shredder, a feed port is arranged on the top of the automatic opening and closing mechanism, and an end cover is arranged on the feed port.

[0013] In the above-mentioned fully automatic garbage disposal pulverizer, the stepped pulverizing teeth include a disc-shaped body, the outer ring of which is provided with at least two teeth in a rotationally symmetrical manner, and the teeth are bent in the same clockwise direction.

[0014] In the above-mentioned fully automatic garbage disposal pulverizer, there is a spacing between the teeth of adjacent stepped pulverizing teeth, and the distance value of the spacing does not exceed the width of one tooth.

[0015] In the above-mentioned fully automatic garbage disposal shredder, the step shredding teeth are, from top to bottom, step shredding teeth one, step shredding teeth two, step shredding teeth three, step shredding teeth four, step shredding teeth five and step shredding teeth six; the outer periphery of the driving shaft of the shredding motor is sleeved with a stabilizing sleeve, and the step shredding teeth two, step shredding teeth three, step shredding teeth four, step shredding teeth five and step shredding teeth six are sequentially fixed on the outer periphery of the stabilizing sleeve; the step shredding teeth one is fixed to the top end of the driving shaft by anti-slip screws, a mounting hole is opened at the top end of the driving shaft, a positioning hole is opened in the center of the step shredding teeth one, and the anti-slip screws are sequentially penetrated through the positioning hole and the mounting hole from top to bottom to form a fastening connection.

[0016] The operation method of the fully automatic garbage disposal shredder includes the following:

[0017] 1) The drive shaft of the reduction drive motor reverses, driving the pinion to reverse synchronously. Through the meshing connection, the transmission rotating disk rotates forward at a certain angle. All guide slots 1 on the rotating disk move synchronously, and then drive all guide pins 1 to move along guide slot 1. Under the restriction of guide pin 2 and guide slot 2, all sliding plates are driven to rotate and open the opening.

[0018] 2) Pour the kitchen waste from the opened opening into the crushing chamber inside the cylindrical shell, and the driving shaft of the deceleration driving motor rotates forward, driving the pinion to rotate forward synchronously, and the transmission rotating disk is reversed by a certain angle through meshing connection, and all the guide slots 1 on the rotating disk are synchronously turned and moved, thereby driving all the guide pins 1 to move along the guide slots 1, and under the restriction of the guide pins 2 and the guide slots 2, all the sliding plates are driven to rotate and close the opening;

[0019] 3) Turn on the crushing motor and drive several stepped crushing teeth to rotate synchronously through the driving shaft. The food waste touches several stepped crushing teeth rotating at high speed in turn. The stepped crushing teeth, which increase from small to large, turn large pieces of food waste into small pieces, and long strips into short pieces. Finally, the food waste rotating at high speed around the center hits the annular cutting ribs, and its volume and length are further reduced. At the same time, under the action of rotation, the raised cutting blades of the annular cutting ribs and the teeth of the lowest stepped crushing teeth cut the food waste, so that hard and high-fiber food waste can also be processed quickly.

[0020] 4) Then, the food waste, which has become smaller in volume and rotates at a high speed, forms a very large speed difference with the stationary cutting screen. Therefore, when the food waste hits the cutting screen, a very large shear force is generated. Finally, the food waste is cut into very small pieces and flows out from the strip-shaped discharge holes on the cutting screen into the water outlet chamber to be discharged.

[0021] Compared with the prior art, the fully automatic garbage disposal pulverizer and its operation method have the following advantages:

[0022] 1. The large-diameter discharge port is in an open state before pouring in the food waste, so that the food waste can be directly poured into the garbage disposer. When the garbage disposer is started, the feed port is automatically closed and then the material is fed. During the processing of food waste, the splashing food waste is blocked by several closed sliding pieces, and the noise is also sealed inside the machine, which greatly reduces the noise of the machine and greatly improves the user experience when using the machine.

[0023] 2. The crushing flow channel is designed as a spiral volute structure, and the spiral teeth that increase step by step are used for step-by-step crushing, especially for the strong crushing of harder and tough garbage, which is conducive to the rapid discharge of food waste. In addition, the tooth structure on the lowest step crushing teeth can prevent the precipitation and accumulation of food waste when rotating, increase the kinetic energy of food waste when discharged, and make the food waste discharged more quickly and thoroughly. At the same time, food waste with greater kinetic energy is not easy to block the sewer. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, under the action of rotation, the raised cutting blades of the annular cutting ribs and the teeth of the lowest stepped crushing teeth cut the food waste, so that hard and high-fiber food waste can also be processed quickly. 4) Then, the small-volume and high-speed rotating food waste forms a very large speed difference with the stationary cutting screen. Therefore, when the food waste hits the cutting screen, a very large shear force is generated. Finally, the food waste is cut into very small pieces and flows out from the strip-shaped discharge holes on the cutting screen into the water outlet chamber to be discharged.
