A unitized combined assembly type layer hen welfare breeding cage

Abstract

The invention discloses a unitized combined and assembled type egg welfare breeding cage, and belongs to the technical field of livestock machines. The cage comprises supporting legs, a pipe frame, a surface net, perch frame columns, perch bars, a movable door, a manual meadow, a manure scraper, a roller shaft, a manure removal belt, a frame layer, a rolling piece, an egg rolling piece, synchronous teeth, an egg collecting belt, a nipple water drinking device, an egg baffle, a trough, a water drinking pipe, an egg laying box body, a connection pin, an interlayer door and an egg conveying channel. The cage can provide functions of egg collecting, conveying, eating, perching, frame connecting and the like. The cage is complete in structural function, can meet welfare habit behaviors of laying hens such as grabbing for rest, scratching and laying in the cage, can also meet the production requirements for automatic manure removing, egg collecting and the like, and greatly improves the welfare breeding level of laying hens; due to the modularized producing, manufacturing and assembling mode, multiple cages can be connected and assembled, the device manufacturing and investment cost is reduced, the space occupation of a single hen is further increased, and the cage conforms to the development tendency of industrial welfare breeding.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry machinery, and in particular relates to a unitized combined assembly type welfare breeding cage for laying hens. Background technique [0002] At present, more than 100 countries or regions in the world have formulated industry standards or legal regulations on animal welfare breeding. As early as 2009, some EU countries such as Germany have requested to gradually transition from the traditional cage-raising production mode of laying hens to the welfare breeding mode of poultry such as large-cage rearing and free-range rearing, cage flat rearing and organic rearing. In view of the basic national conditions of my country's large population, small per capita arable land area, and large egg consumption volume, coupled with the profit-seeking demand of breeding enterprises for maximizing economic benefits, it is still difficult for my country to fully realize the free-range free-range breedin...

In view of the basic national conditions of my country's large population, small per capita arable land area, and large egg consumption volume, coupled with the profit-seeking demand of breeding enterprises for maximizing economic benefits, it is still difficult for my country to fully realize the free-range free-range breeding model of welfare-oriented laying hens in the short term

[0003] Chinese patent CN 102944406 B discloses a device and method for the load test of the bottom net of the welfare cage for laying hens, which provides structural parameters for the design and development of the overall structure of the welfare cage for laying hens, and is the best choice for the design and installation of welfare cages for laying hens Theoretical basis; Chinese patent application 201510496197.7 discloses a chicken cage for improving the welfare level of laying hens. It is equipped with an egg-laying area and a rest area, which can reduce the breakage rate of eggs and improve the quality of chicken feet and skin feathers of laying hens. However, there are also disadvantages such as the low utilization rate of the space between the two areas, light leakage in the egg-laying area, and non-automatic egg collection.

Chinese patent CN203105293 U discloses a welfare-type overlapping layer cage raising mechanism, but it also has the disadvantage that it can only partially meet the animal welfare and automatic production requirements of layer hens
