Technical Field
The invention belongs to the field of pasture cleaning equipment, and particularly relates to a dairy cow manure pit with a disinfection function.
Background
In the traditional breeding industry, people usually adopt a manual cleaning mode to clean the cowshed, the personnel cost is high, the labor intensity is high, and the cleaning mode can not keep up with the requirement of social progress. With the large-scale development of the cattle breeding industry, particularly, cattle breeding in pens is a relatively dense place, and a lot of excrement is digested and discharged by animals every day, which brings trouble to clean the excrement and achieve clean breeding.
In order to solve the above problem, chinese patent (application number is CN201120025486.6) discloses that an electronic cleaning cow dung recovery vehicle includes cow dung loading truck, casing, universal wheel, motor, electric control ware, and the motor links to each other with electric control ware, and electric control ware is established on cow dung loading truck, and the universal wheel is installed on cow dung loading truck, be equipped with power pulley, first drive belt, second drive belt, first pulley bearing housing shaft, second pulley bearing housing shaft on the casing, power pulley installs on the motor, installs the radius spiral plate under the first pulley bearing housing shaft, installs fan-shaped brush cleaner under the second pulley bearing housing shaft, and first drive belt cover is between first pulley bearing housing shaft of power pulley, and second drive belt cover is between first pulley bearing housing shaft and second pulley bearing housing shaft. The motor is started through the electric controller, the motor provides power for the power belt pulley, rotary power is generated through transmission of the first transmission belt and the second transmission belt, the fan-shaped sweeping brush sweeps cow dung into the arc-shaped bent shell under the action of the bearing sleeve shaft of the second belt pulley in a high-speed rotating mode, the radius rotating plate throws the cow dung swept into the shell into the cow dung loading vehicle according to the rotating speed difference of the radius rotating plate and the first belt pulley bearing sleeve shaft in the high-speed rotating mode, and the purposes of sweeping and recycling are achieved.
Although the above patent solves the cleaning of the feces, the bacteria generated from the feces stay in the excretion place, and continuously generate new bacteria, especially parasites in the feces, which easily induce cattle diseases.
Disclosure of Invention
The invention aims to provide a cow manure pit with a disinfection function, and aims to solve the technical problems that bacteria generated by excrement can stay in a excretion place after the excrement is cleaned, new bacteria are continuously generated, particularly parasites in the excrement are easy to induce cattle diseases.
The cow manure cleaning tank with the disinfection function comprises a base and a cow house, wherein the cow house is arranged above the base, a bushing is arranged at the bottom of the cow house and further comprises a sliding chute plate, sliding chutes for horizontal reciprocating motion of the bushing are arranged on two sides of the sliding chute plate, the sliding chutes are located on the lateral sides of the bushing, the two sides of the bushing are in lap joint with each other and are arranged on the sliding chutes, a cleaning net is arranged on the bushing and is used for pushing the horizontal reciprocating motion of the bushing, a storage cavity is formed in the bottom wall of each sliding chute, a plurality of liquid spraying holes are formed in the side faces of each sliding chute, each liquid spraying hole is provided with a first hinge and a second hinge, and the orientations of the first hinge and the second hinge are opposite.
The principle of the scheme is as follows: the cleaning solution is filled in the storage cavity in advance, when the dairy cow excretes excrement in the dairy cow house, the excrement can fall into the base from the dairy cow house, the cleaning net is moved, the cleaning net pushes the bushing plate to move on the sliding chute plate in a reciprocating mode, meanwhile, the cleaning net cleans the excrement on the base and moves the excrement to a set position, in the cleaning process, because the first hinge and the second hinge of the liquid spraying hole are opposite in orientation, the cleaning solution is divided into three strands of sprayed cleaning solution through the liquid spraying hole, the first strand of sprayed cleaning solution is sprayed to the cleaning net through the first lily, and the cleaning net stained with the excrement is disinfected and cleaned; the second strand of the sprayed cleaning solution is the cleaning solution sprayed to the dairy house through the second lily leaves, and the dairy house stained with the excrement is disinfected and cleaned; the third jet of cleaning solution is sprayed to the base through the gap between the first hinge and the second hinge, and the base stained with the excrement is disinfected and cleaned.
The beneficial effect of this scheme lies in: when the dairy cows excrete in the dairy cow house, the excreted excrement falls onto the base, the cleaning net is moved, the cleaning net pushes the excrement to a certain specified position in a centralized manner, and the excrement stays at a place.
Furthermore, a telescopic baffle is arranged in the sliding groove and used for plugging the liquid spraying hole, and one side of the telescopic baffle is lapped on the bushing. The leakage plate pushes the telescopic baffle plate to move, so that the blocked liquid spraying hole is exposed.
Furthermore, the telescopic baffle plate consists of a fixed plate and a movable plate, a movable chute for the movable plate to slide in the fixed plate is arranged in the fixed plate, and the movable plate is connected with the bushing plate. The bushing plate is convenient to push to move on the chute plate.
Further, the bushing is net-shaped. The drain plate is in a net shape, so that the contact surface between excrement and the drain plate is small, and cleaning and disinfection of cleaning solution are facilitated.
Furthermore, a supporting column for supporting the chute plate is arranged on the base. In order to support the chute board and the milk tank.
Further, a septic tank is arranged on the base. The excrement is convenient to collect.
