The motor transmits power to the clutch 4-2 through the transmission belt 4-3, and drives the nut sleeve 4-9 to rotate, so that the lead screw 4-1 threadedly connected thereto drives the piston 4-6 to do a linear reciprocating motion in the briquetting drying cylinder 4-4, thereby realizing garbage extrusion and ejection. In addition, on the basis of the above disclosed embodiment, a motor protection structure can be added to the clutch 4-2, and it can be set that when there is too much garbage in the briquetting drying cylinder 4-4, the right end teeth of the clutch 4-2 are disengaged from the left end teeth, and the power cannot be transmitted to the nut sleeve 4-9, thereby realizing the function of protecting the motor.

[0044] The preferred implementation of the utility model is as follows: start the cover opening device, and close the cover opening device after the garbage is thrown. The garbage falls into the middle of the two crushing rollers of the coarse powder module. The two crushing rollers move relative to each other to achieve the coarse powder crushing of the kitchen waste. The crushed garbage falls into the fine powder module under the action of gravity. During the crushing process, the drum and the blade rotate simultaneously to crush the garbage into granules to achieve the kitchen waste fine powder. The finely ground garbage falls into the briquetting and drying module through the hopper to achieve the garbage extrusion operation. At the same time, the briquetting and drying cylinder is equipped with an electric heating tube, which can dry the wet garbage into dry garbage, which is convenient for extrusion into blocks. After the extrusion is completed, the electric gate opens, and the block garbage is regularly transported to the designated location by the transfer vehicle for further processing.

[0045] The structural design of the utility model is scientific and reasonable, and is easy to implement. It can crush and recycle kitchen waste into solid organic materials, thereby improving the recycling rate of resources. At the same time, it treats waste at the source, reduces the demand for large-scale centralized treatment facilities, and thus reduces construction and operating costs. In addition, the present invention can process kitchen waste in a timely manner, and there will be no problem of emission of harmful chemicals during the treatment process, which can effectively reduce the breeding of pathogens and pests and reduce public health risks.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
