Description

Technical Field

[0001] The utility model relates to a manure discharge device and a system used in a pig farm. Background Art

[0002] The existing mainstream pig farms use the water bubble manure discharge mode, and special staff use manure plugs to regularly discharge the accumulated pig manure for many days. Since the pig manure needs to stay at the bottom of the pig house for many days, the humidity and odor in the pig house are very high, which is very unfavorable to the growth of pigs. In addition, the odor emitted by the pig house to the surrounding area is often complained by the surrounding villagers.

[0003] A Chinese patent with publication number 210017383U discloses a manure plug opening device, which mainly includes a manure plug for blocking the manure outlet in the breeding house; an operating rod, one end of which is connected to the manure plug; and an elastic component, which is connected to the operating rod and provides energy for the movement of the operating rod. Accordingly, the staff can use the manure plug opening device without having to look for the manure plug in the manure pit, thereby avoiding the safety hazard of setting an inspection cover for opening the inspection port, and has a certain auxiliary effect to help open the manure plug. Although this patent solves the problem of opening the manure plug, it still requires manual regular operation and cannot solve the problem of odor.

[0004] The patent with publication number 218921238U discloses an electrically controlled leakage device and a manure leakage system. The electrically controlled leakage device includes a support frame, a plug body, and an electrically controlled driving mechanism for driving the plug body to rise and fall; the support frame includes a plurality of pillars and a mounting plate or mounting frame on the top of the pillars; the electrically controlled driving mechanism is installed on the support frame; the plug body is used to block or open the pipe mouth under the action of the electrically controlled driving mechanism. When the pipe mouth is opened, fluid substances or powdered substances can flow out through the pipe mouth. Although the electrically controlled leakage device can realize regular automatic feces discharge, it requires the intervention of a control device. Once a fault occurs, maintenance is difficult, and power supply wiring is required, which is costly.

[0005] Therefore, it is necessary to design a new excrement discharge device for pig farms. Utility Model Content

[0024] Beneficial effects:

[0025] The excrement discharge device and system for pig farms of the utility model have the following advantages:

[0026] (1) It can significantly reduce the odor in the pig house and the surrounding environment.

[0027] Since the valve can discharge accumulated manure in time, there is less manure and less odor in the pig house, which is beneficial to the growth of pigs. Moreover, due to the less odor, the number of fans in the pig house can be reduced, which significantly saves energy and reduces consumption.

[0028] (2) No need for electronic control equipment, simple, practical and low cost.

[0029] The mechanical structure is used to achieve automatic feces discharge, without the need for electronically controlled valves, wiring and power supply. It is low-cost and easy to promote and implement, and has a low failure rate and is easy to maintain later.

[0030] (3) It is beneficial to reduce the construction cost of pig farms
