Problems solved by technology

[0004] Therefore, in order to reduce this heat stress response, in the prior art, it is usually accomplished by spraying to cool down, but simply relying on spraying, the cooling effect is relatively slow, and there are the following problems: 1. Spraying relies on manual control, Breeders rely on their own experience to judge whether to open and close the sprinkler system, which is not only inconvenient to operate, but also requires high experience for the breeders, which is not conducive to alleviating the heat stress response of dairy cows; 2. The spray water is room temperature water and needs to rely on fans To cool down the spray water and then fall on the cows to take away the heat, the cooling effect is poor; 3. The spray water has high hardness and is easy to condense at the nozzle, blocking the spray hole and affecting the spray effect; 4. When spraying for a period After a period of time, when the sprayed water mist reaches a certain concentration, the cows will feel uncomfortable due to the reduction of oxygen

Embodiment Construction

[0035] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0036] The present invention provides a spray system that can quickly reduce the heat stress response of dairy cows. The overall innovation of this system includes the following parts:

[0037] 1. In terms of the structure of the sprinkler system in the overall barn: convert the existing form of fan-guided water mist into a form of self-adjusting spray. The cooling water is directly atomized and then sprayed to improve the cooling efficiency and play a role in rapid cooling.

[0038] 2. In terms of the sensing of the spraying system: the existing cowshed uses infrared sensing to check whether the cattle are in the spraying position. The invention adopts the dual detection method of infrared and water mist detector, the infrared sensor is directly below the nozzle rod, and can respectively sense whether the cattle are in the spraying position, and ...

Abstract

The invention relates to a spraying system capable of quickly reducing heat stress reaction of a dairy cow. The spraying system comprises a fence, a spraying unit, a high-pressure water pump, a water purifier, a cooling-water machine, a water mist concentration detector, an in-place sensor and a control unit, and is characterized in that the spraying unit, the water mist concentration detector and the in-place detector are correspondingly mounted on the fence, a water inlet of the spraying unit is sequentially connected with the high-pressure water pump, the cooling-water machine and the water purifier through a pipeline, and the control unit is in control connection with the spraying unit, the high-pressure water pump, the water purifier, the cooling-water machine, the water mist concentration detector and the in-place sensor correspondingly. The invention further designs a water curtain cooling mechanism consisting of a water curtain box and a fan, so that the heat stress reaction of the dairy cow caused by high temperature is further reduced. The water-saving purpose is achieved mainly through two technical means, firstly, whether dairy cow are in the position or not is reflected through the in-place sensor; and the water mist concentration sensor is additionally arranged to sense the water mist concentration in real time, so that an electromagnetic valve is controlled to be opened and closed, and the purpose of saving water is achieved.

Description

technical field [0001] The invention belongs to the field of stockbreeding, and relates to a device capable of cooling stockbreeding, in particular to a spray system capable of rapidly reducing the heat stress response of dairy cows. Background technique [0002] Dairy cows continuously absorb energy from feed to meet the needs of life and production, while continuously releasing heat to the environment. If the heat energy cannot be released in time or the release is blocked, the cow will have a sick reaction, which is the so-called heat stress. The heat load on the cow is not only the heat generated by the cow itself, but also the sum of the superimposed thermal effects produced by the heat in the environment (including air temperature, relative humidity, air flow and sunlight radiation). [0003] Therefore, when the high temperature in summer comes, the higher ambient temperature will cause discomfort to the body of the cow, causing it to produce heat stress. After the h...
