The hard materials in kitchen wastes are greatly different, for example, the hard materials in the household kitchen wastes are mainly bones, occasionally magnetic sheets, wood-plastic products and the like, and almost no metal materials exist. However, in public places such as hotels and dining halls, hard materials such as ceramic products, wood-plastic products, stones and metals are found in the kitchen wastes every time in an investigation, although the hard materials are very large in bone proportion.

Aiming at the situation, a kitchen waste hard object smashing device is developed and installed at the front end of kitchen waste processing equipment to smash hard objects in the kitchen waste, large hard objects in the kitchen waste do not need to be manually selected, personnel are prevented from working under severe conditions, labor cost is saved, rear-stage equipment is effectively protected, reliability and service life of the equipment are improved, and resource recycling efficiency is improved.

Disclosure of Invention

The processing equipment of kitchen wastes at present has not a good solution to the hard matters in the kitchen wastes, although the manual sorting is carried out, the hard matters still cause the problems of frequent failure of the processing equipment, high operating cost and the like, and in order to solve the problems, the invention provides the kitchen wastes hard matters crushing device which can crush different hard matters in the kitchen wastes, such as large bones, ceramics, metal matters and the like; the device is arranged on kitchen waste processing equipment to process kitchen waste, hard materials in the kitchen waste are not required to be sorted manually, the operation efficiency of the equipment is improved, the failure rate of the equipment is reduced, and the operation cost is saved.

The technical scheme adopted by the invention for solving the technical problems is as follows: a kitchen waste shredder comprising: the bone cutting machine comprises a belt pulley (1), a transmission gear (2), a box body (3), a bone cutting knife I (4), a bone cutting knife II (5), a shaft I (6), a shaft II (7), a bearing cover (8), a special cleaning knife strip (9) and a self-lubricating bearing (10); wherein, the shaft I (6) and the shaft II (7) rotate simultaneously and have opposite directions, so that the bone crushing cutter I (4) and the bone crushing cutter II (5) also rotate in opposite directions to form a bone crushing mode for milling cutting. The cutting edge angle of the bone crushing knife is very large, and the hard objects are extruded and crushed when being cut and crushed.

According to the hard kitchen waste smashing device, the shaft I and the shaft II externally connected with the power source (6) rotate simultaneously, the directions are opposite, so that the bone smashing knife I (4) and the bone smashing knife II (5) rotate in opposite directions, and a bone smashing mode of milling and cutting is formed.

The kitchen waste hard object crushing device has the advantages that the cutting edge angle of the bone crushing knife is large, and hard objects are extruded and crushed when being cut and crushed.

The kitchen waste hard object smashing device is calculated and tested, the cutting edge angle of the bone smashing knife is 87.3 degrees +/-1 degrees, the smashing effect of hard objects is good, the probability of damage of the cutting edge of the bone smashing knife is low, the failure rate of equipment is reduced, and the reliability and the running cost of the equipment are effectively improved.

Foretell hard thing reducing mechanism of kitchen remainder, bone knife I (4) are dog-tooth form with bone knife II (5) and distribute, can adjust through the interval between I (6) of axle and II (7) of axle, adjust the distance between the bone knife to reach the hard thing granularity size after the adjustment is smashed, satisfy the supporting requirement of different equipment.

The kitchen waste hard object smashing device is provided with the special cleaning blade strip for self cleaning of the cutter, can treat wound objects such as plastics and ropes wound on the cutter and crushed auxiliary hard objects, and does not need to specially clean the cutter.

The invention has the beneficial effects that:

1) the kitchen waste hard object smashing device can smash hard objects in kitchen waste, the hard objects do not need to be manually sorted, personnel are prevented from working in a severe environment, and labor cost is reduced.

2) The damage of hard objects to the kitchen waste treatment equipment is avoided, the reliability of the equipment is improved, the maintenance cost of the equipment is reduced, and the service life of the equipment is prolonged.

3) The efficiency of kitchen waste recycling is improved, and secondary pollution of hard matters in the kitchen waste is avoided.
