Wheat washing machine with self-cleaning function

Abstract

The invention discloses a wheat washing machine with a self-cleaning function. The wheat washing machine comprises an outer cylinder which is arranged vertically, a water tank located under the outer cylinder, a feeding port which is located in one side of the outer cylinder and communicated with the water tank, a sewage discharging port which is located in the other side of the outer cylinder and communicated with the water tank, a rotating shaft which is arranged inside the outer cylinder and is capable of rotating, and a drum sieve arranged between the rotating shaft and the outer cylinder. A spiral blade is arranged on the rotating shaft in the axial direction of the rotating shaft. A discharging port is formed in the upper portion of the outer cylinder. The wheat washing machine further comprises a water outlet pipe communicated with the water tank. A water pump is arranged on the water outlet pipe. A lid body is arranged at the top of the outer cylinder. A water cavity is formed in the lid body. The upper end of the water outlet pipe is communicated with the water cavity. The rotating shaft is provided with a hollow cavity. The water cavity can be communicated with the cavity. A plurality of spray nozzles are formed in the rotating shaft in the axial direction of the rotating shaft. The spray nozzles face the screen surface of the drum sieve.

Description

technical field [0001] The invention relates to a wheat processing machine, in particular to a wheat washing machine with self-cleaning function. Background technique [0002] Agricultural products will inevitably be stained with dirt, dust or pesticides during the process of growth, harvesting or storage. In order to ensure that the processed agricultural products are clean, they must be washed before processing. The washing methods of agricultural products include immersion method, spray washing method, friction decontamination method and ultrasonic washing method. The washing machines used are usually drum-type washing machines. The main structure of an existing drum-type washing machine includes: a vertically arranged outer cylinder, a water tank located at the lower part of the outer cylinder, and a feed port located on one side of the outer cylinder and connected to the water tank. , the sewage outlet on the other side of the outer cylinder connected with the water ta...

AI Technical Summary

Problems solved by technology

However, there is a problem with this type of drum washing machine for wheat: after long-term use, more dirt will remain on the drum sieve, and the wheat will cause secondary pollution after contacting the drum sieve, which will affect the cleaning quality , the existing method is to directly take out the cylinder screen from the outer cylinder, and then manually clean it after taking it out, which is troublesome to operate and low in cleaning efficiency
