Description
Technical field
The invention belongs to ventilation equipment field, be specifically related to a kind of accurate ventilation unit in part of milk cow neck cooling for open cowshed cow heat stress relief in summer.
Background technology
The cow heat stress problem that summer high temperature causes is one of major reason of restriction China milk industry development always.Milk cow produces heat stress, can significantly reduce feed intake, the milk yield of milk cow, and affect health and the fertility of milk cow, even causes death.Present stage, from environment control angle, milk cow is carried out to Physical temperature-lowering, the method that solves cow heat stress is mainly divided into three major types: 1. reduce solar radiation, as: build shade structures.2. increase in house and ventilate, as: longitudinally force ventilation.3. apply evaporative cooling system, or will be 2., 3. combine use, as mist cooling, the cooling of spray+fan system, bath etc.
Disclosed Chinese invention patent CN101268760A on September 24 " cooling device for barnyard " in 2008, this device has adopted house shading system drive sunshade net to launch and close up, simultaneously, adding above the compound sunshade net of absorbent material evenly mounting spray head, so both can prevent that too much moisture from directly falling to causing on the ground sport surface muddy, can allow again moisture on sunshade net, continue evaporation, reduce air themperature.This way is mainly used in the reduction of the environmental temperature of the sports ground of half-open or open cowshed.
Disclosed Chinese invention patent CN1633843A on July 6th, 2005 " domestic animal Microcomputerized self-controlled spray cooling device ", after this device adopts water atomization, ejection is the water smoke of falling umbrella, and domestic animal is played to certain cooling effect, has alleviated domestic animal heat stress.But the mist cooling of this mode makes fogdrop diameter too little, can not penetrate ox hair, not only do not reach the skin of ox, increase on the contrary air humidity, ventilating fan, away from ox body, can not well be taken away Evapotranspiration heat in addition, has affected cooling-down effect.
Disclosed Chinese invention patent ZL201210593457.9 " a kind of target ventilation unit of cow heat stress relief " in 2014, this device is arranged on target ventilation shaft on the strength cangue or bed of milk cow, concentrate and search for food or couch the period milk cow, carry out cow heat stress relief reaction for the neck position of milk cow by the direct air-supply of wind pushing hole.But due to the effect of air-spray, there is dispersion in air-supply exit flow in the time arriving milk cow neck position.And the active component of the neck of milk cow to be Physical temperature-lowering alleviate heat stress, precisely air-supply could directly effective cow heat stress relief therefore need to carry out part for milk cow neck.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of accurate ventilation unit in part for milk cow neck cooling, this device is the cow feeding stage in summer open cowshed, for the neck position of milk cow, local precisely air-supply arrangement is installed on neck cangue top, is carried out cow heat stress relief.

The first reducer pipe 5 is connected by the first air-supply straight tube 7, the second bend pipe 8 and the second air-supply straight tube 13 with air outlet 9.
The aperture size of described the second straight tube 6 is from the junction of the first bend pipe 3 to reducing step by step away from cold wind unit 1 one end.
Described air outlet 9 is provided with adjusting louver 12.
Beneficial effect of the present invention is:
1, above the present invention's each group neck cangue in open cowshed, milk cow neck position arranges an accurate ventilation shaft in part, each device for cleaning pipeline is crossed cold wind unit blasting air, reduce step by step balanced ventilation by straight-run of pipe and through bend pipe junction to far-end, and at each tapered pipeline place, straight-run of pipe is set, blow by rectangular air supply opening through bend pipe, therefore in the time that the stage of searching for food, milk cow head was positioned at neck cangue, comfortable local uniform air-supply environment can be enjoyed in the neck position of milk cow.
2, the present invention is directly installed on air outlet at the position of neck cangue top milk cow neck,, precisely blows in the cow feeding stage for the local neck position of milk cow air cooling-down by cold wind unit, directly effectively alleviates the heat stress of milk cow.
3, the present invention utilizes cold wind unit, the air after cooling is delivered to accurately to the position of the neck of milk cow body part, and the air after cooling can not use spray equipment, has reduced the generation of the dirty waste water in dairy farm.
4, the present invention has installed the blinds that can regulate air supply direction at rectangular air supply opening place, can make local relief more comfortable soft.
5, the present invention can be widely used among livestock breeding and animal-breeding local ventilation.
