Description

Technical Field

[0001] The invention relates to the technical field of agricultural breeding manure treatment, in particular to an electric self-propelled manure cleaning and loading and unloading machine. Background Art

[0002] With the development of agricultural breeding technology, large-scale breeding and standardized breeding construction have become a new development trend for breeders, and corresponding mechanized breeding equipment has also appeared on the market. However, in the process of livestock and poultry breeding, manure cleaning is still mainly done manually, usually using tools such as shovels and iron spades, with poor cleaning efficiency and effect. Therefore, manure cleaning equipment is increasingly favored by breeders. At present, there are three main types of manure cleaning equipment on the market, namely, scraper manure cleaning machine, hand-pushed shovel manure cleaning machine and small shovel manure cleaning machine. However, there are different disadvantages in cleaning manure in large-scale breeding processes: for scraper manure cleaning machine, the manure cleaning process is just to scrape the manure in the pen to one side of the pen through the scraper, and then remove it by manual loading and unloading of manure, which has the problem of low mechanization and affects the efficiency of manure cleaning; for hand-pushed shovel manure cleaning machine, manure is mainly piled up together by manually pushing the shovel head and then removed, and this cleaning machine also has the problem of low mechanization and slow manure cleaning; for small shovel manure cleaning machine, although it has the functions of shoveling, loading and unloading, and transporting manure, it adopts a four-wheel structure driven by diesel or gasoline, which is not only inconvenient to turn in the pen, but also not suitable for manure cleaning in the pen; and the shovel head of this model is mainly used for solid manure cleaning, and there is a phenomenon of missed shovel when cleaning manure, which makes its manure cleaning effect poor. Summary of the invention

[0005] The steering wheel operating mechanism adopts an electric three-wheel steering mechanism composed of a steering wheel, a joystick connected to the steering wheel, a steering column connected to the bottom end of the joystick through a universal joint, and a steering connecting rod connected to the steering column.

[0006] The hydraulic lifting cylinder consists of a cylinder body, an oil tank installed at the lower part of the cylinder body through an oil pipe, an oil pump connected to the oil tank, an oil pump motor connected to the oil pump, and a relay arranged on the oil pump motor. The relay is connected to the battery pack through a wire, and is connected to a travel switch and a three-speed handle switch through a hydraulic control circuit. The three-speed handle switch is arranged on the rear end face of the casing.

[0007] The electric drive axle assembly is connected to the electric vehicle controller through an electrical control circuit and then connected to the battery pack.

The hydraulic lifting cylinder is lifted and lowered to drive the lifting chain, and the lifting chain pulls the upper and lower guide wheels to move in the fixed guide rail, so that the push shovel can be lifted and lowered. When the push shovel is lowered to the inner arc angle loading bend at the lower part of the fixed guide rail, the push shovel head contacts the ground during the forward movement of the frame to clean and load feces and sewage, which is beneficial to improving the feces and sewage cleaning effect; when the push shovel is raised to the outer arc angle unloading bend at the upper part of the fixed guide rail, the push shovel tilts downward to unload feces and sewage; when the push shovel is raised to the vertical part of the fixed guide rail, the push shovel head is lifted up for transportation during the forward movement of the frame, forming a mechanized feces and sewage cleaning equipment integrating cleaning, loading, transportation and unloading, so that it has a high degree of mechanization and improves the feces and sewage cleaning efficiency.
