Description

Technical Field

[0001] The invention relates to a drinking fountain for livestock and poultry, in particular to a lever-type drinking fountain for waterfowl to drink water. Background Art

[0002] Waterfowl mainly include ducks, geese, swan geese, grey geese and other poultry animals that live on the water surface. During the breeding process, drinking fountains are needed to provide water for waterfowl. At present, the drinking fountains used for waterfowl breeding on the market are mostly divided into two categories: direct drinking trough drinkers and nipple drinkers.

[0003] The structure of the direct drinking water tank water dispenser is as follows Figure 1 As shown, it includes a float switch and a PVC pipe with holes or grooves; when waterfowl need to drink water, they put their heads into the trough to obtain water. There is always water in the trough of the drinking fountain with this structure. Food residues and pollutants are easily dropped into the trough. After fermentation, harmful bacteria will be produced, which endangers the health of waterfowl. It requires manual high-frequency cleaning and disinfection, which is labor-intensive and difficult to achieve the purpose of thorough cleaning. In addition, when waterfowl drink water, mud pits or mud will form on the ground in the drinking area, which can easily cause pollution to the waterfowl feathers and affect the appearance and sales price of the waterfowl. Nipple drinkers can be divided into ball valve type nipple drinkers and cone valve type nipple drinkers. The structure of the ball valve type nipple drinker is as follows: Figure 2 As shown in the figure, it includes a housing, a valve body, a back cover, a water control rod, a top rod, a steel ball and an O-ring. Figure 3 As shown, it includes an outer shell, a valve body, a water control rod and a top rod. When waterfowl need to drink water, they touch or lift the top rod with their beaks to open the water flow channel of the drinker, and the water flows out through the water flow channel, and the waterfowl obtains clean drinking water at the bottom of the top. Nipple drinkers can effectively prevent food residues and pollutants from falling into the drinking water, but because the top rod is completely exposed, waterfowl can touch the top rod from all directions, often resulting in reduced water drinking and low drinking efficiency due to excessive competition; waterfowl have a large demand for drinking water. In order to ensure that the waterfowl have enough drinking water, breeders often increase the water pressure and increase the water output per unit time, but a large part of the water will leak out from the gap in the beak (such as Figure 4 As shown in the figure, the amount of water leakage may even exceed the amount of water consumed, resulting in a waste of water resources and high humidity in the house. More importantly, when using existing conventional nipple drinkers, waterfowl often have a poor comfort during drinking, and only certain postures are suitable for waterfowl to drink relatively comfortably. Summary of the invention

[0004] In view of the technical problems mentioned in the background technology, the present invention aims to provide a lever-type drinking fountain for waterfowl.

[0005] The present invention adopts the following technical solution.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] Combination Figure 5-7 As shown, a lever-type drinking fountain for waterfowl includes a holder, the holder includes an integrally formed buckle 1 and a mounting tube 2, the buckle 1 includes a clamping plate 11 with a certain elasticity, one end of the clamping plate 11 is formed with a U-shaped groove 12, the inner wall of the U-shaped groove 12 is provided with a plurality of tooth grooves 13, the other end of the clamping plate 11 is provided with a plurality of tooth-shaped protrusions 14, the clamping plate 11 is connected to form a closed ring through the tooth grooves 13 and the tooth-shaped protrusions 14 at both ends, so that the holder is fixedly installed on the drinking water pipe 6; the buckle 1 also has a plurality of tooth-shaped protrusions 14 on the inner wall of the U-shaped groove 12, and the clamping plate 11 is provided with a plurality of tooth-shaped protrusions 14 on the inner wall of the U-shaped groove 12. An arc-shaped elastic block 15 is provided. After the buckle 1 is installed on the drinking pipe 6, the elastic block 15 is abutted against the outer wall of the drinking pipe 6, so that the connection between the clamping seat and the drinking pipe 6 is tighter; a stepped hole adapted to the outer shape of the cone valve type nipple drinking fountain 7 is provided in the mounting tube 2, and a connecting sleeve 3 is detachably installed on the outside of the mounting tube 2. A plurality of limiting columns 21 are provided on the outer wall of the mounting tube 2, and a plurality of "L"-shaped limiting grooves 31 are provided on the connecting sleeve 3. The mounting tube 2 and the connecting sleeve 3 are connected into a whole through the limiting columns 21 and the limiting grooves 31.

[0022] Among them, the lower end of the connecting sleeve 3 is provided with an inclined guide plate 4, the guide plate 4 and the connecting sleeve 3 are integrally formed, the cross section of the guide plate 4 is arc-shaped, and the two sides of the guide plate 4 are provided with a slot 41. The guide plate 4 is provided with a lever 5, and a limit sleeve 51 is fixed in the middle of the lever 5. A rotating rod 52 is inserted in the limit sleeve 51, and the two ends of the rotating rod 52 are respectively rotatably installed in the slot 41 of the guide plate 4, and the lever 5 is located below the rotating rod 52 (as one of the key points of the present invention, the function of such a setting is to effectively guide the water flowing out of the cone valve type nipple drinking fountain 7 to flow smoothly and slowly into the beak / mouth of the waterfowl in a flat fluid state, and prevent the water flowing out of the cone valve type nipple drinking fountain 7 from entering the beak / mouth of the waterfowl in a large amount in a short time and in an approximately columnar fluid state, so as to avoid the waterfowl from choking). When in use, the limit sleeve 51 and the rotating rod 52 are driven to rotate synchronously during the rotation of the lever 5.

[0023] like Figure 6-7 As shown, a protrusion 53 is provided at the upper end of the lever 5, and the protrusion 53 can be abutted against the lower end of the top rod of the cone valve nipple waterer 7. There is a gap between the lower end of the lever 5 and the guide plate 4, and the lower end of the lever 5 does not extend out of the guide plate 4; by setting the lever 5 to be retracted, that is, the lever 5 does not extend out of the guide plate 4, it can prevent leakage caused by waterfowl playing in the water, thereby further avoiding waste of water resources, reducing the humidity in the house, and improving the cleanliness of the waterfowl feathers; and the lever 5 can only be bitten and pulled from a fixed direction to open the top rod, and only one waterfowl is provided with water at a time, which can avoid the waterfowl from drinking less water due to excessive competition and improve the drinking efficiency.

[0024] In this embodiment, as the second key point of the present invention, the radial cross section of the guide plate 4 is arc-shaped, the inner cavity of the guide plate 4 can accommodate the upper beak of the waterfowl, the bottom wall of the guide plate 4 is used to abut against the lower beak of the waterfowl, and the lower part of the guide plate 4 is used to extend into the beak of the waterfowl, and the lower part of the lever 5 is used to abut against the end of the upper beak of the waterfowl; the angle between the center line of the guide plate 4 and the horizontal plane can be selected within the range of 35-50°. Among them, the top surface of the protrusion 53 is an arc surface, and when the cone valve nipple drinker 7 is in a closed state, the top of the protrusion 53 just abuts against the lower end of the top rod of the cone valve nipple drinker 7, and the low point of the front of the protrusion 53 abuts against the inner wall of the guide plate 4. The lever 5 is a flat structure.

[0025] When in use, it can be directly applied to the drinking line equipped with the cone valve nipple drinking fountain 7, which can reduce the transformation and development costs of the enterprise and also reduce the manufacturing cost of the product. The installation process is as follows Figure 8As shown, a threaded hole is drilled on the drinking pipe 6, and the cone valve type nipple drinking fountain 7 is installed in the threaded hole. Then the holder of the lever type drinking fountain is sleeved on the outside of the cone valve type nipple drinking fountain 7, and the holder is fixed to the drinking pipe 6 by the buckle 1. Then, the lever 5 is installed on the guide plate 4 through the rotating rod 52, and the connecting sleeve 3 is installed on the outside of the mounting tube 2, so that the protrusion 53 at the upper end of the rotating rod 52 is against the top rod of the cone valve type nipple drinking fountain 7.

[0026] like Fig. 9 As shown, when the waterfowl drinks water, the beak bites and pulls the lower end of the lever 5, the lower end of the lever 5 rotates downward and abuts against the surface of the guide plate 4, and the upper end of the lever 5 rotates upward, so that the protrusion 53 pushes the top rod upward to open the water flow channel of the cone valve type nipple drinker 7, and the water in the drinking pipe 6 flows into the connecting sleeve 3 through the cone valve type nipple drinker 7, and the guide plate 4 introduces the water into the beak of the waterfowl; after the waterfowl finishes drinking water, the beak releases the lower end of the lever 5, and the top rod of the cone valve type nipple drinker 7 is reset under the action of gravity, that is, the water flow channel is closed.

[0027] Due to the use of the lever-type drinking fountain with the above-mentioned specific structure, as long as the angle between the beak of the waterfowl and the horizontal plane is controlled within the range of 15~70°, the waterfowl can drink water comfortably. There are dozens of corresponding waterfowl postures, one of which is as follows: Fig. 9 As shown, at this time, the angle between the center line of the waterfowl beak and the horizontal plane is about 25° (while in the traditional scheme, Figure 2-4 , the waterfowl's beak centerline and the vertical plane form an angle range of about 20±3° to drink water relatively comfortably, and the waterfowl postures corresponding to this state do not exceed 3). It should be noted that the use of the aforementioned specific lever 5 in conjunction with the guide plate 4 at a specific angle can greatly expand the comfortable drinking posture of the waterfowl, which is very critical and has the advantage of accurately regulating drinking water.

[0028] The lever-type drinking fountain in this scheme is more in line with the biological characteristics of waterfowl. It can not only significantly reduce the amount of water leaking from the beaks of waterfowl when drinking, but also improve the comfort of waterfowl when drinking. More importantly, it expands the postures of waterfowl for comfortable drinking. There are many postures suitable for waterfowl to drink relatively comfortably. The drinking fountain in this scheme can prevent leakage caused by waterfowl playing in the water, thereby further avoiding waste of water resources, reducing the humidity in the house, and improving the cleanliness of waterfowl feathers. During use, only one waterfowl is provided with water at a time, which can avoid the reduction of water drinking volume due to excessive competition among waterfowl and improve the drinking efficiency of a single waterfowl. The lever-type drinking fountain in this scheme is simple in structure, practical, low in manufacturing cost, easy to install and replace, and has a long service life. In particular, the sealing of the cone valve nipple drinker is not easy to fail. More importantly, the present invention can effectively guide the water flowing out of the cone valve nipple drinker to flow smoothly and slowly into the beak / mouth of waterfowl in a flat fluid state, preventing the water flowing out of the cone valve nipple drinker from entering the beak / mouth of waterfowl in a large amount and in a nearly columnar fluid state in a short period of time, thereby avoiding the waterfowl from choking and further improving their comfort during the drinking process.
