A large multi-span cowshed

Abstract

The invention relates to a large multi-span cowshed. The large multi-span cowshed is characterized by comprising an integral rectangular cowshed body defined by a plurality of stand columns, four outer walls and a reverse V-shaped double pitch roof, partition walls parallel with the short outer walls of the rectangle are arranged in the outer walls at intervals and divide the integral rectangular cowshed body into a plurality of independent cowshed cells, the center of each cowshed cell in the longitudinal direction is provided with a feeding channel, two rows of cow lying beds which are arranged oppositely are arranged on the two sides of each feeding channel and parallel to the feeding channel, the positions, corresponding to the feeding channels, of the outer walls are provided with lifting doors respectively, the two sides of each lifting door are provided with an opening and a roller blind respectively as air inlets, the other end, opposite to each air inlet, of the corresponding outer wall is provided with a negative pressure fan as an exhaust port, the position, adjacent to the other end of each feeding channel, of the corresponding partition wall is provided with a lifting door, and each cowshed cell is internally provided with a blowing board and an underground excrement collection ditch. The corresponding cowshed cells and environment control modes can be selected according to different climate conditions of the south and the north, and the large multi-span cowshed can be widely applied to various cowshed construction projects.

Description

technical field [0001] The invention relates to a cattle house, in particular to a large multi-span cattle house. Background technique [0002] As a new architectural style of dairy houses, large-scale cowsheds dominated by mechanical ventilation have been widely used in cowshed building technology. Compared with naturally ventilated barns, the microenvironment of large barns with mechanical ventilation is less affected by changes in the external environment, and it is relatively easy to realize human adjustment and control in the small environment, which can effectively improve the living and production environment of cattle . Large-scale cowsheds that mainly adopt mechanical ventilation are generally single-story cowsheds with large space. Each cowshed can accommodate more than 2,000 lactating cows. This kind of cowshed similar to a rectangular box saves land. The advantages of easy management and relatively good environmental control are sought after by more and more dai...

AI Technical Summary

Problems solved by technology

However, in actual operation, this large barn has the following problems: 1. Due to the large space in the barn, there are many obstacles in the barn that block the smoothness of the air flow, the air flow in the barn is poorly organized, and the air flow is unevenly distributed. Especially in the vicinity of the roof deflector will produce a large area of ​​severe air turbulence

2. Due to the low level of environmental control, the phenomenon of high temperature and high humidity in summer and low temperature and high humidity in winter is serious. To a certain extent, it has an adverse impact on the health of dairy cows and the production efficiency of cattle farms

3. Traditional multi-span buildings mostly use inverted W-shaped roofs. The defect of this type of roof is that serious ice accumulation will occur at the sunken gutters in winter in the north.
