Description
Technical field
The invention belongs to livestock and poultry cultivation field, it is used for that cow house is aeration-cooling to be penetrated at a distance more particularly to a kind of summer
Streaming point mouth ventilating system.
Background technology
At present, the quality of livestock and poultry cultivation environment is paid close attention to by countries in the world, and wherein milk cattle cultivating environment is particularly important.With
Flourishing for milk industry, the quality of its breeding environment is played a very important role in whole agricultural development.Summer, China
Most area meeting continuous high temperatures, and high temperature can cause heat stress to milch cow, the feed intake of milch cow is greatly lowered, gives milk
Amount, and affect milch cow health and fertility, therefore, summer milch cow is carried out effective temperature-reducing alleviate heat stress to close weight
Will.At present, improving the method for cow heat stress mainly has：1st, solar radiation is reduced, such as：Sunshade knot is built in milch cow sports ground
Structure；2nd, temperature in house is reduced, such as：Mist cooling, spray-fan for cooling, wet curtain-blower fan cooling etc..Cow feeding, couch etc. it is big
Part-time is carried out all in cowshed, thus cooling becomes apparent to the effect for reducing cow heat stress in house.
At this stage, the building structure of cow house is usually mono- depth span of 6m, and whole cowshed enters profound 100~200m
.The conventional common flow-disturbing blower fan range of cow house is 8~10m, also has inventor to design a kind of pusher ventilating system, can
So that the range of ventilating system is extended to into 18~20m.But the cow house very big for depth, the range of ventilating system is more remote,
The blower fan quantity for using is fewer, and the energy consumption that whole system is saved is also more.On the premise of alleviation cow heat stress is met,
The form and range of ventilating system are improved as much as possible, can in large quantities save initial stage input cost and the later stage of milk cattle cultivating
Operating cost.
Compared to patent application 201410791038.5, a kind of entitled ' pusher flat mouth ventage for cow house
System ', the range of the jetting type point mouth ventilating system of the present invention is farther, and the air outlet of sharp-mouth type is not only longitudinally carrying out passage point
Every, also from laterally being divided, separate gas channel more uniform, exit flow also add gas while more stablizing
Flow velocity degree, so as to more improve the range of ventilating system.For the cow house of depth very big (length is very big), ventilating system is penetrated
The increase of journey, can directly reduce the usage amount of blower fan, with reducing energy consumption.
The content of the invention
For the problems referred to above, it is an object of the invention to provide a kind of be used in the interior feeding area of cowshed or couch in area, summer energy
Enough available ventilations, cooling, the long-range jetting type point mouth ventilating system for cow house for alleviating cow heat stress.
For achieving the above object, technical scheme is as follows：
A kind of jetting type point mouth ventilating system for cow house, including centrifugal blower 2, deep bead 3, sharp mouth air outlet 4,
Demarcation strip 5, bendable kuppe 6 and ventilation casing 7, wherein, the centrifugal blower 2 is located inside ventilation casing 7, with ventilated box
Body 7 is fixedly connected, and the air inlet 8 of centrifugal blower 2 is located at the side of ventilation casing 7, and the bendable kuppe 6 is arranged in
The homonymy of the fan outlet 9 of centrifugal blower 2, is fixedly connected with ventilation casing 7；The sharp mouth air outlet 4 is led positioned at bendable
The end of stream cover 6；Wherein：
The deep bead 3 is fixedly connected with bendable kuppe 6, and the longitudinal direction of bendable kuppe 6 is divided into into three passages；
The demarcation strip 5 is fixedly connected with bendable kuppe 6, and bendable kuppe 6 is laterally divided into into two passages；
The upper surface of bendable kuppe 6 is downward-sloping, and the angle with the vertical plane of ventilation casing 7 is α；The sharp mouth
Diagonally downward, the angle with the upper surface of bendable kuppe 6 is β to air outlet 4；The lower surface of bendable kuppe 6 is two-stage nitration
Bending, wherein, a section of close point mouth air outlet 4 is leading portion, and leading portion is horizontal segment；One section of close ventilation casing 7 is back segment,
Back segment is downward-sloping relative to horizontal segment, and the inclination angle of back segment is γ.
The upper surface of bendable kuppe 6 is 70~75 ° with the angle α of the vertical plane of ventilation casing 7；The sharp mouth goes out
Air port 4 is 70~75 ° with the angle β of the upper surface of bendable kuppe 6；The back segment of the lower surface of bendable kuppe 6 inclines
Oblique angle γ is 2~6 °.
Upper surface length L1 of the bendable kuppe 6 is 1.05~1.25m；The width L2 of sharp mouth air outlet 4 is 0.2
~0.3m；Length of length L3 of the lower surface leading portion of the bendable kuppe 6 less than the lower surface back segment of bendable kuppe 6
L4。

Fast further to improve, when milch cow is in slight heat stress, the wind speed of ventilating system is entirely capable of reaching the effect of cooling, and works as milk
Cattle is then turned on spray equipment when being in severe heat stress, delays the use of spray equipment and can more reasonably utilize and save water money
Source, the yield for reducing sewage, while good cooling-down effect can also be reached.
4th, present configuration is simple, and jetting type point mouth ventilating system and spray equipment are arranged by the way of intersecting, sharp mouth
The air-flow of ventilating system is consistent with the spray jet direction of spray equipment, and the drop of spray is directly sprayed at Contents in Cows by blower fan
On, due to the effect of jet, spray water droplet is not only able to penetrate the fur layer of Niu Tibiao and through skin surface, moreover it is possible to one
Fixed spraying intensity, makes the crushing effect of water droplet and the spray regime of water droplet be obtained for raising and improve, and more effectively alleviates
The heat stress of milch cow.
