A method for sealing the water-soaked manure drainage ditch of pig houses in cold regions

Abstract

The invention discloses a sealing method for an excrement-in-water drainage ditch of a hog house in a cold region. According to the sealing method, a sealing device is additionally arranged inside theexcrement-in-water drainage ditch of the hog house in the cold region for sealing, and comprises a sealing plate array and slipways, the sealing plate array consists of a plurality of rotary sealingplates which are buckled to sealing plate connecting rods, and the sealing plates can slide along the slipways through pulleys; the slipways consist of horizontal slipways and vertical slipways whichare fixedly installed on the two side walls of the excrement-in-water drainage ditch in a pairing manner. The device is in a normally closed state, excrement can be cleaned regularly, so that the concentration of harmful gas and heat loss in the hog house in the cold region can be greatly lowered, the effect is obvious, energy source is saved, and the cost is low.

Description

technical field [0001] The invention relates to an animal husbandry device, which is a method for sealing the water-soaked manure drainage ditch of pig houses in cold regions. Background technique [0002] In the process of pig breeding, it is an extremely important technical measure to maintain a suitable temperature and humidity in the pig house and reduce the concentration of harmful gases. Existing pig houses in cold regions are generally closed structures, and the feces are discharged by soaking manure in water in the house. Because the manure is stored in the ditch for a long time, the manure will ferment and produce harmful gases, resulting in Harmful gases increase, so vents have to be installed on the side wall of the blister dung sewage ditch, and forced ventilation is used to reduce the concentration of harmful gases in the pig house, which not only wastes energy, but also reduces the temperature of the pig house, especially in winter , Increased heating costs, a...

Problems solved by technology

Existing pig houses in cold regions are generally closed structures, and the feces are discharged by soaking manure in water in the house. Because the manure is stored in the ditch for a long time, the manure will ferment and produce harmful gases, resulting in Harmful gases increase, so vents have to be installed on the side wall of the blister dung sewage ditch, and forced ventilation is used to reduce the concentration of harmful gases in the pig house, which not only wastes energy, but also reduces the temperature of the pig house, especially in winter , increasing the heating cost, and, with the increase of ventilation, it is bound to generate air flow on the surface of the house to form wind, which is easy to cause pigs to catch a cold
