Door structure of swinery feeding equipment

Abstract

The invention discloses a door structure of swinery feeding equipment. The door structure comprises an entering channel and an exiting channel; a feeding trough is arranged between the entering channel and the exiting channel; left and right door hinges are respectively arranged at left and right sides of the inlet of the entering channel, and a return spring and a door lock mechanism are installed between two doors; a barrier door and a folding door mechanism are sequentially arranged behind the left and right door hinges; the folding door mechanism is composed of a primary folding door and a secondary folding door with the front end which is hinged with the middle part of the primary folding door; tensioning springs which are at an anticlockwise expansion tendency all the time are arranged at the tail end of the secondary folding door and the end part of the primary folding door; the barrier door and the primary folding door can be rotated along installation rotary shafts of respective end parts and are provided with corresponding return springs which enable door faces to be naturally vertical to the side edges of the channels. According to the door structure provided by the invention, a plug is arranged for self-protection and companions are moderately expelled by using the forward-movement power to eat through the interaction of the left and right doors, the barrier door and the folding door mechanism, so that the direct attack is avoided and the serious incidents such as crushing injury, abortion and the like which are caused by acute behaviors of pigs are avoided.

Description

technical field [0001] The invention relates to automatic feeding equipment for pigs, in particular to a door structure for feeding equipment for pigs. Background technique [0002] The existing feeding equipment used for pig group feeding has become a feeding station again. The entrance door is divided into left and right half doors, one is pushed and pulled by the cylinder, and the other is the dislocation of the two half doors, forming a larger The gap, opened by the arching of the pig's mouth, enters the feeding station for food. But no matter what kind of feeding station with the entry door method, it cannot prevent the latter pig from entering the feeding station at the same time as the previous pig. In a previous application, a feeding device for pigs was disclosed, including an entry passage and an exit passage, with a trough between them, and a left door and a right door at the entrance of the entry passage. A return spring and a door lock mechanism are installed ...
