Control door for channel for pig to enter and exit for individual feeding and feeding device

Abstract

The invention discloses a control door for a channel for a pig to enter and exit for individual feeding and a feeding device. The control door comprises a rotating shaft mechanism, a control door overturning seat, a limiting chain and an overturning door; the rotating shaft mechanism comprises a rotating shaft, a first cross bar and a connecting piece connecting the rotating shaft with the first cross bar; the control door overturning seat is arranged above the rotating shaft; the limiting chain is connected with the control door overturning seat and the first cross bar so as to limit the angle of the first cross bar rotating around the rotation axis; the overturning door includes two overturning door panels between which an obtuse angle is formed by taking the first cross bar as an intersection line; and the angle of rotation of the first cross bar controls an obtuse angle opening formed by the two overturning door panels to be an entrance of the pig to enter the channel or an exit for the pig to exit channel. The invention further provides a feeding device comprising the control door for the channel for the pig to enter and exit for individual feeding, and the pig individually feeds through the control door. The control door and the feeding device reduce the cost of raising equipment of a raiser, and saves time and effort.

Description

technical field [0001] The invention relates to the technical field of livestock breeding equipment, in particular to a control door and a feeding device for pigs that can advance and retreat individually for feeding passages. Background technique [0002] In the prior art, the door mechanism that allows group pigs to eat alone, see figure 1 , the doors are mostly two opposite doors. The door includes a shaft rod 2 and several wheel rods 3 of the same length. A cross bar 4 is connected to the upper end of the shaft rod. On, the upper side free end of cross bar 4 is provided with stopper 5, and each wheel bar 3 is arranged at an angle with the plane where cross bar 4 and rotating shaft bar 2 are located, and the free end of each wheel bar 3 is equipped with plastic wheel 6, The rotating shaft of the plastic wheel is arranged vertically, one of the doors is installed on one side of the front side of the door frame through the two ends of the rotating shaft rod, and the other ...

Problems solved by technology

Further, the door structure requires the pigs to arch the first door to open backwards, and then arch the second door to open forwards, so that the pigs can enter to eat alone. When the door mechanism is actually used, it is necessary to manually train the pigs. It takes a week to open the door mechanism autonomously, which increases the requirements for farmers to raise pigs, is laborious and time-consuming, and increases time and labor costs
