Description
Technical Field
The utility model relates to the technical field of livestock breeding machinery, in particular to intelligent constant-temperature constant-liquid-level milk cow trough equipment.
Background
It is well known that milk is 87% water. Every 1 kg of fresh milk produced by a cow needs 3-5 kg of water. Therefore, ensuring sufficient drinking water for the cows is of great importance in the production process of the large-scale pasture.
At present, centralized water supply equipment is widely applied to various large-scale pastures, but still has many problems, which are mainly reflected in the following 5 aspects:
1. the water feeding and discharging speed is slow: the water feeding and discharging system of the water tank is unreasonable in design, so that the water feeding and discharging speed is low: the slow water feeding speed causes that the drinking water of the dairy cows needs to wait, particularly, the dairy cows which have just squeezed milk from the milk hall and return to the cowshed consume a large amount of water in the body due to milk secretion, and are separated from a water source for a long time and need to be replenished at the first time, the water feeding speed of the water tank is too slow, so that the drinking time of the preceding dairy cows is prolonged, the following dairy cows have to queue for waiting, and the milk yield of the next stage is reduced due to untimely drinking. The efficiency of washing the water tank is reduced due to the slow water discharging speed, and for the water tank with a part of manual water discharging plugs, a cleaner needs to completely discharge dirty water out of the water tank and cover the water discharging plugs to complete the whole washing operation, so that the washing quantity of the water tank in unit time is reduced.
2. The parameter control is not accurate: the parameters such as the liquid level height and the water temperature of the water tank are not accurately controlled. Most of the existing water tanks adopt a floating ball valve to control the liquid level height, and the liquid level control is not accurate due to mechanical errors. In the in-service use process, because can't realize the accurate control of liquid level, installer need heighten the actual liquid level height of basin, avoids the water capacity that causes because of the error not enough. The excessive water capacity not only reduces the heating efficiency of the water tank, but also increases the amount of sewage generated by rear-end cleaning. Inaccurate water temperature control leads to too high or too low heating temperature, and reduces the drinking willingness of the cows.
3. The heating energy consumption is high: the existing water tank heating device is mainly characterized in that a plurality of strip-shaped heating plates are attached to the bottom end of a tank body, the heating speed is low, heating blocks are heated unevenly, and the heating energy consumption is high.
4. Automatic cleaning cannot be realized: the current basin still adopts artifical abluent mode more, and the cleaning efficiency is low, and the milk cow stress is big in the cleaning process.
5. The intelligent degree is low: current basin is mostly single-machine control, need independent adjustment basin parameter to different regions and service environment, can't reach network deployment control, and degree of automation is lower.
