[0001] The utility model relates to the technical field of poultry drinking fountains, in particular to a drinking fountain for chicks. Background Art
[0002] In large-scale chicken farms, the way chickens drink water is a very important link. In the past, chicken farms often used trough drinking water. This drinking water method, because the water stays in the trough for a long time, dirt will enter the trough, thus becoming a breeding ground for pathogenic bacteria. With the continuous development of breeding technology, this backward drinking water method has been replaced by various drinking nipples.
[0003] The method of using the drinking nipple is: the chicken pecks the moving rod on the drinking nipple with its beak, and the moving rod moves to open the water outlet, so that water flows out of the water outlet, and the chicken drinks water automatically. However, when the chicken touches the moving rod with too much force to open the water pipe, a large amount of water in the water pipe flows out, which will cause choking for the chicken, especially for the chicks, due to the large water flow; for the farm, a large amount of drinking water is lost, and the breeding cost becomes higher; secondly, the beaks of newly born chicks are soft, and pecking the drinking nipple directly will cause stress reactions in the chickens, affecting the early growth of the chickens.
[0004] Therefore, the prior art needs to be further developed. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0030] According to an embodiment of the utility model, a chick drinking device is provided. Figures 1 to 7, including: a drinking bowl 1, on which a column 11 is arranged; a water outlet assembly 2, which is connected to a water pipe 3, and includes a moving rod 21 and a water outlet 22, from which water in the water pipe 3 flows out; the moving rod 21 is movably arranged relative to the water outlet assembly 2, and the moving rod 21 moves to open or close the water outlet 22; a telescopic assembly 4, which includes an elastic member 41, which is connected to the column 11, and the column 11 is driven to move by the elastic member 41, so that the top of the column 11 pushes the moving rod 21 to move, thereby opening the water outlet 22; a fixing assembly 5, which is connected to the telescopic assembly 4, and the fixing assembly 5 is connected to the water pipe 3, and the telescopic assembly 4 and the drinking bowl 1 are connected to the water pipe 3 through the fixing assembly 5. The column 11 is arranged in the middle position of the drinking bowl 1, and extends upward from the center of the bottom of the bowl. The drinking bowl 1 is located below the telescopic component 4, which is below the fixed component 5. The water outlet component 2 passes through the water pipe 3 and enters the tube cavity. The water outlet 22 is blocked or opened by the movement of the moving rod 21, so that water flows into the drinking bowl 1. When the chick drinker is fixed on the water pipe 3, the elastic member 41 is in a compressed state. When water needs to be poured into the drinking bowl 1, the elastic member 41 starts to reset and drives the column 11 to move upward, pushing the moving rod 21 to move upward. After the end of the moving rod is misaligned with the water outlet 22, the water outlet 22 is opened, and the water in the water pipe 3 flows into the drinking bowl 1. The drinking bowl 1 sinks due to gravity, driving the column 11 to move downward. Similarly, the moving rod 21 also moves downward due to gravity until the end of the moving rod 21 blocks the water outlet 22, thereby stopping water from being poured into the bowl. During the downward movement, the elastic member 41 is compressed again. As the chicks drink more water, the water in the bowl gradually decreases. When the weight of the bowl is less than the elastic force of the elastic member 41, the elastic member 41 drives the column 11 to move upward, and pushes the moving rod 21 to open the water outlet 22 again, and starts to fill the drinking bowl 1 with water. This cycle is repeated, and no manual intervention is required to achieve automatic drinking of poultry. The chick drinking device of this embodiment solves the technical problem that the existing automatic poultry drinking devices in the related art are not convenient for chicks to drink water automatically.
[0031] In the chick drinking device of the present embodiment, the bottom of the drinking bowl 1 adopts a sealing structure, which can not only avoid the risk of water leakage, but also prevent impurities from entering when the drinking bowl 1 is suspended on the water pipe 3, thereby reducing the subsequent cleaning work.
[0032] See also Figure 1 and Figure 2 In the chick drinking device of this embodiment, the water outlet assembly 2 further includes a shell 23, one end of which passes through the water pipe 3 and enters the water pipe 3, so that the water outlet 22 is located in the water pipe 3, and the moving rod 21 is movably arranged in the shell 23. The shell 23 penetrates into the water pipe 3, so that the water outlet 22 is located in the water pipe 3, ensuring that water will not spill out from the water outlet 22.
[0033] See also Figure 2 and Figure 3 In the chick drinking device of this embodiment, the moving rod 21 includes a first moving rod 211 and a second moving rod 212, which are arranged in sequence along the vertical direction, and the first moving rod 211 and the second moving rod 212 are both arranged in the shell 23. The water outlet 22 includes a first water outlet 221 and a second water outlet 222, which are arranged in sequence along the vertical direction in the shell 23. The first moving rod 211 moves to open or close the first water outlet 221, and the second moving rod 212 moves to open or close the second water outlet 222. A cylinder 24 is also provided in the shell 23, and a first water outlet 221 and a second water outlet 222 are provided on the inner wall of the cylinder 24. The first moving rod 211 and the second moving rod 212 move in the vertical direction at the first water outlet 221 and the second water outlet 222 respectively. The two moving rods are provided to cooperate with the two water outlets for synchronous use, so that the water outlet can be controlled more sensitively. The diameter of the end of the first moving rod 211 is adjusted to increase the gap between the shell 23 and the first moving rod 211, thereby changing the water outlet speed; by providing the second moving rod 212 of different lengths, the moving path of the second moving rod 212 is extended, thereby adjusting the amount of water in the drinking bowl 1. This design can be flexibly selected according to the situation of breeding poultry.
[0034] See also Figure 1 and Figure 3 In the chick drinking device of this embodiment, the column 11 includes a pushing portion 111, a necking portion 112 and a vertical rod portion 113.

The diameter of the constricted part 112 is smaller than that of the pushing part 111. The annular stopper 42 is sleeved on the constricted part 112 and abuts against the pushing part 111. Such a design enables the annular stopper 42 to exert a thrust on the pushing part 111 to the maximum extent when the spring 411 is reset, so that the pushing part 111 moves upward to push the moving rod 21 to open the water outlet 22. The annular stopper 42 is mounted on the neck portion 112 in the form of a buckle, which is easy and convenient to install with low cost.
[0036] See also Figure 4 and Figure 5 In the chick drinking device of this embodiment, the sleeve 43 is detachably connected to the fixing assembly 5, so that the telescopic assembly 4 is detachably connected to the fixing assembly 5; the fixing assembly 5 is detachably connected to the water pipe 3. The telescopic assembly 4 and the fixing assembly 5 are detachable to facilitate replacement of the drinking bowl 1; the fixing assembly 5 and the water pipe 3 are detachable to facilitate replacement of the chick drinking device.
[0037] See also Figure 4 , Figure 5 and Figure 6 In the chick drinking device of this embodiment, two slots 431 are arranged on the sleeve 43, and the two slots 431 are arranged opposite to each other. Two clamping columns 51 are arranged on the fixed component 5, and the two clamping columns 51 are arranged opposite to each other. When the telescopic component 4 is connected with the fixed component 5, each slot 431 is located in each clamping column 51. When connecting, first fix the water outlet component 2 and the fixed component 5 on the water pipe 3, and after the telescopic component 4 is connected with the drinking bowl 1, hold the sleeve 43 of the telescopic component 4, and connect the clamping column 51 on the fixed component 5 to the corresponding slot 431, so as to connect the entire chick drinking device with the water pipe 3.
