A water supply device for pig breeding

Abstract

This utility model relates to the technical field of pig breeding and care equipment, and discloses a water supply device for pig breeding, including a body. A water tank is fixedly installed on the top of the body, a filter screen is fixedly installed on the inner wall of the bottom of the body, and a water outlet pipe is fixedly installed on the outer wall of the bottom of the water tank. A water intake unit is provided at the end of the water outlet pipe away from the water tank. By providing a water intake unit, when a pig drinks water, it pushes the water intake component towards the bottom of the water outlet pipe. Through several arc protrusions arranged in a linear array of different sizes in the movable cavity, the square rod does not return to its original position quickly during the return process under the elastic force of the return spring, but rather returns at a gradually decreasing speed. This prevents the water intake component from returning to its original position quickly during the resealing of the water intake sleeve, thereby extending the amount of drinking water that the pig can obtain after triggering the water intake unit, meeting the pig's needs while reducing drinking water waste.

Description

Technical Field

[0001] This utility model relates to the technical field of pig breeding and maintenance equipment, specifically a water supply device for pig breeding. Background Technology

[0002] Pig drinking devices are essentially just water troughs. Pigs easily contaminate the drinking water when they drink, and the water can easily spoil if left in the trough for a long time. With technological advancements, pig drinking devices have become increasingly efficient and healthier. For example, Chinese patent CN221410045U discloses a water supply device for pig breeding. In this application, when a pig drinks, its mouth covers the valve body, and the tip of its tongue pushes against the valve core, thus pushing the valve core. Water then flows out through the gap between the valve body and the outer wall of the valve core, achieving the purpose of allowing the pig to drink.

[0003] However, in actual use, the above-mentioned device relies on the interaction between the pig's tongue and the valve core to dispense water. When the pig drinks water, it needs to swallow, at which point the valve core cannot dispense water, which to some extent limits the amount of water the pig can take and prolongs the time required for the pig to drink. In view of this, we propose a water supply device for pig breeding. Utility Model Content

[0004] The purpose of this invention is to provide a water supply device for pig breeding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water supply device for pig breeding, comprising a body, a water tank fixedly installed on the top of the body, a filter screen fixedly installed on the inner wall of the bottom of the body, a reflux chamber formed on the inner wall of the bottom of the body, a reflux pump fixedly installed on the inner wall of the reflux chamber, a reflux pipe fixedly connected between the output end of the reflux pump and the outer wall of the top of the water tank, and a water outlet pipe fixedly installed on the outer wall of the bottom of the water tank. A water intake unit is provided at the end of the water outlet pipe furthest from the water tank, the water intake unit comprising:

[0006] A water-taking sleeve is fixedly installed on the outer wall of the bottom end of the water outlet pipe. A fixing ring is fixedly installed on the arc-shaped inner wall of the water-taking sleeve. A water guide column is fixedly installed on the arc-shaped outer wall of the fixing ring. A water outlet is opened on the inner wall of the water guide column. A fixing sleeve is fixedly connected to the inner wall of the end of the water-taking sleeve away from the water outlet pipe.

[0007] The movable cavity is located on the inner wall of the fixed sleeve. One end of a return spring is fixedly installed on the inner wall of the movable cavity. The other end of the return spring is fixedly connected to one end of a square rod. An arc-shaped groove is formed on the arc-shaped outer wall of the square rod. A water-taking component is fixedly connected to the other end of the square rod. A water inlet cavity is formed on the inner wall of the water-taking component. A flow guide cavity is formed on the inner wall of one end of the water inlet cavity. A water outlet groove is formed on the arc-shaped outer wall of the water-taking component.

[0008] Preferably, the water-collecting component includes a cylindrical block and a conical block fixed to each other. The conical block has a large-diameter end and a small-diameter end. The large-diameter end is located near the side of the cylindrical block, and the conical block is located at the end of the cylindrical block away from the water outlet pipe. In the initial state, the small-diameter end of the conical block extends out of the water-collecting sleeve to facilitate the pig's tongue to lick it.

[0009] Preferably, the end of the cylindrical block has an annular cavity adapted to the fixing sleeve, and the fixing sleeve is disposed inside the annular cavity, so that the water-collecting component can only slide in the horizontal direction when it is pushed and displaced.

[0010] Preferably, the cylindrical block of the water intake component has a cylindrical hole at its center that matches the outer diameter of the water guide column, and the end of the water guide column is located inside the cylindrical hole, so that when the water intake component is squeezed and slides towards the end of the water outlet pipe, it can slide relative to the water guide column.

[0011] Preferably, the inner wall of the movable cavity is provided with arc-shaped protrusions that are adapted to the size of the arc-shaped groove, and the arc-shaped protrusions are arranged in a linear array. The diameter of the arc-shaped protrusions gradually decreases from the fixed sleeve side to the square rod, so that the square rod will not directly and quickly return to its original position when it is reset by the elastic force of the reset spring.

[0012] Preferably, an auxiliary displacement component is provided on the outer side of the water-taking sleeve. The auxiliary displacement component includes a silicone sleeve, which is fixedly installed on the arc-shaped outer wall of the water-taking sleeve. A squeezing arc block is fixedly installed on the arc-shaped inner wall of the silicone sleeve, and a pressure-bearing arc block is fixedly installed on the arc-shaped outer wall of the cylindrical block of the water-taking component.

[0013] Preferably, a rectangular cavity with a width that matches the width of the squeezing arc block is provided on the arc-shaped outer wall of the water intake jacket, and both the squeezing arc block and the pressure-bearing arc block are disposed inside the rectangular cavity.

[0014] Compared with the prior art, this utility model provides a water supply device for pig breeding, which has the following beneficial effects:

[0015] 1. This water supply device for pig breeding, by setting up a water intake unit, pushes the water intake component to one side of the bottom of the water outlet pipe when the pig drinks water. Through several arc protrusions arranged in a linear array of different sizes in the movable cavity, the square rod does not return to its original position quickly when it is reset by the elastic force of the return spring. Instead, it resets at a gradually decreasing speed. This prevents the water intake component from returning to its original position quickly when the water intake sleeve is resealed, thereby extending the amount of drinking water that the pig can obtain after triggering the water intake unit when drinking water, meeting the pig's needs while reducing drinking water waste.

[0016] 2. This water supply device for pig breeding, by setting up an auxiliary displacement component, during the process of pig biting, the squeezing of the silicone sleeve by the pig's mouth causes the squeezing arc block to move towards the center of the water intake sleeve, thereby squeezing the pressure arc block. This pressure arc block causes the water intake component to slide towards the bottom of the water outlet pipe, thus triggering the water intake unit to release water. This avoids the limitation of relying solely on the pig's tongue to lick water, and improves the water supply efficiency of the device in the actual pig breeding water supply process.

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a water supply device for pig breeding, including a body 1, a water tank 2 fixedly installed on the top of the body 1, a filter screen 3 fixedly installed on the inner wall of the bottom of the body 1, a reflux cavity opened on the inner wall of the bottom of the body 1, a reflux pump 4 fixedly installed on the inner wall of the reflux cavity, a reflux pipe 5 fixedly connected between the output end of the reflux pump 4 and the outer wall of the top of the water tank 2, a water outlet pipe 6 fixedly installed on the outer wall of the bottom of the water tank 2, and a water intake unit 7 provided at the end of the water outlet pipe 6 away from the water tank 2. The water intake unit 7 includes a water intake sleeve 71, a fixing ring 72, a water guide column 73, a water outlet 74, a fixing sleeve 75, a movable cavity 76, one end of a return spring 77, a square rod 78, an arc groove 79, a water intake component 710, a water inlet cavity 711, a guide cavity 712, and a water outlet groove 713.

[0024] In one embodiment of this utility model, a water-taking sleeve 71 is fixedly installed on the bottom outer wall of the water outlet pipe 6. A fixing ring 72 is fixedly installed on the arc-shaped inner wall of the water-taking sleeve 71. A water guide column 73 is fixedly installed on the arc-shaped outer wall of the fixing ring 72. A water outlet 74 is opened on the inner wall of the water guide column 73. A fixing sleeve 75 is fixedly connected to the inner wall of the end of the water-taking sleeve 71 away from the water outlet pipe 6. A movable cavity 76 is opened on the inner wall of the fixing sleeve 75. One end of a return spring 77 is fixedly installed on the inner wall of the end of the movable cavity 76. One end of a square rod 78 is fixedly connected to the other end of the return spring 77. An arc-shaped groove 79 is opened on the arc-shaped outer wall of the square rod 78. A water-taking component 710 is fixedly connected to the other end of the square rod 78. A water inlet cavity 711 is opened on the inner wall of the water inlet cavity 711. A flow guide cavity 712 is opened on the inner wall of one end of the water inlet cavity 711. A water outlet groove 713 is opened on the arc-shaped outer wall of the water-taking component 710.

[0025] Furthermore, the bottom end of the water outlet pipe 6 is horizontally positioned to facilitate the pig's biting and drinking. Simultaneously, the water intake sleeve 71 is sleeve-shaped, and the water guide column 73 is horizontally positioned at the axis of the water intake sleeve 71. Specifically, the water intake component 710 includes a cylindrical block and a conical block fixed to each other. The conical block has a large-diameter end and a small-diameter end, with the large-diameter end positioned closer to the cylindrical block. The conical block is positioned at the end of the cylindrical block furthest from the water outlet pipe 6. In the initial state, the small-diameter end of the conical block extends out of the water intake sleeve 71 to facilitate the pig's tongue licking, and the movement of the pig's tongue propels the water intake component. 710 moves toward the center of the water intake sleeve 71. Specifically, the end of the cylindrical block has an annular cavity that matches the fixed sleeve 75, and the fixed sleeve 75 is disposed inside the annular cavity so that the water intake component 710 can only slide in the horizontal direction when it is pushed and displaced. In addition, the cylindrical block of the water intake component 710 has a cylindrical hole that matches the outer diameter of the water guide column 73 at its axis, and the end of the water guide column 73 is disposed inside the cylindrical hole, so that when the water intake component 710 is squeezed and slides toward the end of the water outlet pipe 6, it can slide relative to the water guide column 73.

[0026] In addition, the end of the square rod 78 away from the return spring 77 is fixedly connected to the inner wall of the aforementioned annular cavity, thereby enabling the horizontal movement of the water-taking component 710 inside the water-taking sleeve 71 to be reset, thus preventing the pig's drinking water from being continuously discharged outwards and avoiding waste of water resources. At the same time, the inner wall of the movable cavity 76 is provided with arc-shaped protrusions that are adapted to the size of the arc-shaped groove 79, and the arc-shaped protrusions are arranged in a linear array. The diameter of the arc-shaped protrusions gradually decreases from the fixed sleeve 75 side to the square rod 78, so that when the square rod 78 is reset by the elastic force of the return spring 77, the square rod 78 will not return directly and quickly, but will reset at a gradually slowing speed. This prevents the water-taking component 710 from returning quickly when the water-taking sleeve 71 is resealed, thereby extending the amount of drinking water that the pig can obtain after triggering the water-taking unit 7 when taking water, meeting the pig's needs while reducing the waste of drinking water.

[0027] Specifically, the water guide column 73 is hollow inside, and the outlet 74 is connected to the internal cavity of the water guide column 73. At the same time, the conical block is provided with a water storage chamber, and the flow guide chamber 712 and the outlet trough 713 are all connected to the water storage chamber. When the water intake component 710 slides towards the bottom of the outlet pipe 6, the water guide column 73 enters the cylindrical block of the water intake component 710 until the outlet 74 is aligned with the inlet chamber 711. At this time, the drinking water in the outlet pipe 6 will enter the inlet chamber 711 through the internal cavity of the water guide column 73 and the outlet 74 due to pressure. Then, it will pass through the flow guide chamber 712 and the water storage chamber, and finally be discharged through the outlet trough 713, so that it can be obtained by the pigs and complete the water supply work for pig breeding.

[0028] In an embodiment of this utility model, an auxiliary displacement component 8 is provided on the outer side of the water intake sleeve 71. The auxiliary displacement component 8 includes a silicone sleeve 81, which is fixedly installed on the arc-shaped outer wall of the water intake sleeve 71. A squeezing arc block 82 is fixedly installed on the arc-shaped inner wall of the silicone sleeve 81, and a pressure-bearing arc block 83 is fixedly installed on the arc-shaped outer wall of the cylindrical block of the water intake component 710.

[0029] It is worth noting that a rectangular cavity with a width that matches the width of the squeezing arc block 82 is provided on the arc-shaped outer wall of the water intake sleeve 71. Both the squeezing arc block 82 and the pressure-receiving arc block 83 are located inside the rectangular cavity. During the process of pigs taking water, since they are not highly intelligent creatures, they will also bite the water intake sleeve 71. During the process of pigs biting, the squeezing of the silicone sleeve 81 by their mouths causes the squeezing arc block 82 to move towards the center of the water intake sleeve 71, thereby squeezing the pressure-receiving arc block 83. This causes the pressure-receiving arc block 83 to drive the water intake component 710 to slide towards the bottom of the water outlet pipe 6, thereby triggering the water outlet action of the water intake unit 7. This avoids the limitation of relying solely on the licking of the pig's tongue to achieve water outlet and improves the water supply efficiency of the device in the actual water supply process of pig breeding.

[0030] In this invention, when in use, the water tank 2 is filled with water. When the pig needs to drink, the pig will bite the water-collecting sleeve 71 with its mouth and lick the conical block of the water-collecting component 710 with its tongue. Through the pushing force of its tongue, the water-collecting component 710 slides inside the water-collecting sleeve 71 towards the bottom of the water outlet pipe 6. The water guide column 73 enters the cylindrical block of the water-collecting component 710 until the water outlet 74 is aligned with the water inlet chamber 711. At this time, the drinking water in the water outlet pipe 6 will enter the water inlet chamber 711 through the internal cavity of the water guide column 73 and the water outlet 74 due to the pressure. Then, it will pass through the flow guide chamber 712 and the water storage chamber, and finally be discharged through the water outlet trough 713, thus being obtained by the pig and completing the water supply work for pig breeding.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
