Kitchen crusher control device

Technical Field

The utility model relates to a meal kitchen breaker's field especially relates to a meal kitchen breaker controlling means.

Background

With the improvement of the living standard of people, the catering industry develops rapidly. With the processing and cooking of a large amount of food materials, various kitchen waste accompanied with the food materials is increasing. The kitchen waste is the residual waste after meals of people and the waste components in the cooking process, such as vegetable leaves, vegetable peels, bones, shellfish shells and the like. Wherein, the materials of the kitchen waste are soft and hard mixed, and have different shapes and sizes, which is not beneficial to the treatment of the kitchen waste. The existing method for treating the kitchen waste is to extrude, grind and grind all the kitchen waste into small pieces with proper grain diameter by a kitchen crusher and then carry out concentrated composting fermentation treatment on the waste.

For example, chinese patent with an authorization publication number of CN207899547U, "a high-efficiency kitchen waste crusher", discloses a high-efficiency kitchen waste crusher, and its technical scheme main points are: the crushing assembly is provided with a roller crushing knife rotatably installed in the crushing box and a driving motor used for driving the roller crushing knife to rotate, a plurality of crushing teeth are arranged on the circumferential side face of the roller crushing knife, a row of crushing blocks are arranged on two inner side walls opposite to the crushing box respectively, and a crushing groove for kitchen waste after crushing to pass through is formed between every two adjacent crushing blocks respectively. When the roller crushing knife rotates, the crushing teeth and the crushing blocks shear and crush the kitchen waste.

In actual use, due to different types of the treated kitchen waste, the flowability of a lot of solid kitchen waste after being crushed is still poor, and the kitchen waste is inconvenient to treat. In order to increase the fluidity of the kitchen waste after crushing and grinding, a water inlet device can be added on the kitchen crusher so as to add water into the kitchen waste entering the kitchen crusher. However, before starting up the machine, an operator needs to manually open the water inlet device to flush and pre-feed the equipment, and after the equipment is closed, the operator also needs to manually close the water inlet device after the equipment is flushed by water, so that the water inlet link is not matched with the crushing link and the operation is complicated, and therefore the improvement is needed.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a meal kitchen breaker controlling means for meal kitchen breaker automatic water supply earlier before normal operating washes, just automatic stop supplies water after treating meal kitchen breaker stop work, has solved the link of intaking and broken link non-assorted problem, has simplified operating procedure.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a kitchen crusher controlling means, which comprises a motor, a switch, grinding assembly, the delivery pipe, motor contactor, the solenoid valve, first relay and auxiliary relay, motor drive grinding assembly, the delivery pipe is washed by water to grinding assembly, auxiliary relay's normally open contact includes normally open contact K12 and normally open contact K13, solenoid valve and delivery pipe switch-on, motor contactor's coil is established ties with the normally open contact of first relay, the coil of first relay is established ties with auxiliary relay's normally open contact K13, auxiliary relay's coil and switch are established ties, the coil of solenoid valve is established ties with auxiliary relay's normally open contact K12.
