Description

Technical Field

[0001] This invention relates to a self-cleaning drinking water device for chicken coops, specifically in the field of water trough cleaning technology. Background Technology

[0002] For chicken farms, water quality is directly related to the health of the chickens. Currently, rectangular water troughs are widely used for feeding laying hens in large-scale, stacked chicken houses. However, the air inside these houses contains a large amount of dust and other harmful substances, which can easily dissolve in the drinking water and cause diseases in the hens. Cleaning rectangular water troughs is time-consuming and labor-intensive, requiring farmers to clean each one individually. If cleaning is not timely, bacteria can proliferate in the troughs, hindering the healthy growth of the laying hens. Summary of the Invention

[0003] The purpose of this invention is to design a self-cleaning drinking water device for chicken coops that can automatically clean the water trough.

[0004] The present invention includes a water tank with a left cleaning trough and a right cleaning trough connected to both ends of the water tank. The highest point of the water tank is located in the middle of the bottom surface of the water tank. A water inlet pipe is provided on the wall of the water tank at the highest point. The bottom surface of the water tank gradually decreases between the highest point and the two cleaning troughs on both sides. Each cleaning trough has a cleaning port with a valve on its bottom surface. A cleaning mechanism is provided inside the cleaning trough. Each cleaning mechanism includes at least one cleaning brush that can cooperate with the bottom surface of the cleaning trough. A motor mounting plate is provided above the cleaning brush. The shaft of the cleaning motor mounted on the motor mounting plate is connected to a rotating shaft, which is connected to the cleaning brush.

[0005] Furthermore, each cleaning brush in the cleaning slot consists of at least one cleaning brush. The inner end of each cleaning brush is connected to the center seat via a hinge shaft, and the rotating shaft connected to the motor shaft is fixedly connected to the center seat. A movable sleeve is provided on the rotating shaft and slides with it via a vertical key. A connecting mechanism is provided on the movable sleeve and connected to the middle of each cleaning brush. The two ends of the mechanism are connected to the movable sleeve and the cleaning brush respectively via shafts.

[0006] Furthermore, the lower surface of the motor mounting plate is fixed with the cylinder body of the lifting cylinder. The piston rod of the lifting cylinder points downward and is connected to the movable sleeve through a bearing. The movable sleeve is provided with a connecting mechanism, which is a connecting rod, connected to the middle of each cleaning brush. The two ends of each connecting rod are connected to the cleaning brush and the movable sleeve through hinge shafts, respectively.

[0007] Furthermore, it includes at least two layers of water tanks arranged vertically, each water tank having a cleaning trough at each end, and a cleaning mechanism installed in each cleaning trough. Each central seat in the cleaning mechanism located on the same side of the upper and lower layers has a central hole, and a rotating shaft passes through the central hole of each central seat and is fixedly connected to it.

[0008] Furthermore, it includes at least two layers of water tanks arranged vertically, each water tank having a cleaning groove at each end, and a cleaning mechanism installed in each cleaning groove. Each central seat in the cleaning mechanism located on the same side of the upper and lower layers has a central hole, and a rotating shaft passes through the central hole of each central seat and is fixedly connected to it. The cleaning brush of each cleaning mechanism is connected to the movable sleeve mounted on the rotating shaft by a connecting rod, and the two ends of each connecting rod are connected to the middle of the cleaning brush and the movable sleeve by hinge shafts. The piston rod of the lifting cylinder or the extension rod connected to it is fixedly connected to each bearing in sequence.

[0009] Furthermore, the bracket includes a left bracket and a right bracket, each bracket is provided with a lead screw connected to a lifting motor, a lead screw nut for cooperating with the lead screw and a lifting plate, the lifting plate cooperating with a vertical guide rail installed on the bracket, and a motor mounting plate fixedly connected to the lifting plate.

[0010] Furthermore, each cleaning brush includes an upper brush plate connected to its central seat via a shaft, a rubber pad is provided below the upper brush plate, a lower brush plate is provided below the rubber pad, a flexible lower scraper is fixed on the lower surface of the lower brush plate, and a stepped hole is provided on the upper surface of the upper brush plate, in which a spring is installed, and a bolt passes through the spring, the upper brush plate and the rubber pad and is connected to the lower brush plate.

[0011] Preferably, the outer end of the lower brush plate is bent upwards, and a side scraper that mates with the inner surface of the cleaning groove is provided on the outer surface of the bent portion. This design increases the contact area between the cleaning brush and the inner wall of the cleaning groove, enhancing the cleaning effect on the inner wall of the cleaning groove.

[0012] This invention adds a left and right cleaning trough at both ends of the water tank, and the bottom of the water tank is designed to gradually slope downwards towards both ends. When water is added, the impurities that have settled in the water tank will accumulate in the cleaning troughs at both ends with the water flow, enabling centralized cleaning of the impurities. The cleaning troughs at both ends are equipped with cleaning brushes, which can automatically clean the troughs by controlling the cleaning motor. This invention adopts a multi-layer stacked water tank design, which is suitable for large-scale breeding models in chicken farms. Moreover, each layer of cleaning troughs is connected to the rotating shaft of the cleaning motor, which can clean multiple layers of cleaning troughs at the same time, improving cleaning efficiency.

[0023] by Figure 3 Define the up, down, left, right, front, and back directions in this embodiment.

[0024] As shown in the figure, this embodiment includes a water tank 1, with a right cleaning trough 2 and a left cleaning trough 3 respectively located at the left and right ends of the water tank 1, both of which are connected to the water tank 1. The bottom surface of the inner wall of the water tank 1 is symmetrically sloped, with its highest point located in the middle of the water tank 1. The bottom surface of the water tank 1 gradually decreases between this highest point and the cleaning troughs on both sides. A water inlet pipe 4 is installed above the highest point of the bottom surface of the water tank 1, and the water inlet pipe 4 is fixedly installed on the inner wall of the water tank 1. During the water filling process, it can flush impurities on the bottom surface of the water tank 1 into the cleaning troughs on both sides. A cleaning port 31 is provided at the lower end of each cleaning trough, and a valve 32 is installed in the cleaning port 31. In this embodiment, the valve 32 is a solenoid valve, which can remotely discharge water from the cleaning trough.

[0025] In this embodiment, a three-layer water tank is provided, with a right cleaning tank 2 and a left cleaning tank 3 at both ends of each tank. The cleaning port 31 of the bottom layer is connected to a sewage pipe 33 for the centralized discharge of sewage.

[0026] Each cleaning slot is equipped with a cleaning mechanism, which includes cleaning brushes 10. In this embodiment, two cleaning brushes 10 are provided, symmetrically distributed along the center of the cleaning slot. A center seat 8 is located at the center of the cleaning slot. The outer surface of the center seat 8 has a different diameter structure, and a center hole with a stepped hole structure is opened inside. A rotating sleeve 16 is sleeved on the outer surface of the center seat 8, and the cleaning brushes 10 are rotatably connected to the center seat 8 through the rotating sleeve 16. A roller bearing 9 is provided at the upper part of the center hole inside, and its center hole is fixedly connected to the outer ring of the roller bearing 9. A motor mounting plate 5 is provided above the uppermost cleaning brushes 10, and a cleaning motor 6 is provided above the motor mounting plate 5. A rotating shaft 7 is connected below the shaft of the cleaning motor 6. The rotating shaft 7 extends downward, passes through the first and second cleaning slots, and extends to the third cleaning slot. The rotating shaft 7 is rotatably connected to the center hole of the center seat 8 and fixedly connected to the inner ring of the roller bearing 9. In use, the rotating shaft 7 can support the cleaning slot through the roller bearing 9, and will not drive the cleaning slot to rotate during the rotation of the rotating shaft 7. Vertical keys are symmetrically arranged on the outer surface of the rotating shaft 7 above the center seat 8 of each layer. A movable sleeve 18 is sleeved on the outside of the vertical key, allowing the movable sleeve 18 to rotate with the rotating shaft 7. Connecting mechanisms connected to the middle of each cleaning brush 10 are symmetrically arranged on both sides of the movable sleeve 18. The connecting structure is a connecting rod 17, which connects to the cleaning brush 10. In this embodiment, both ends of the connecting rod 17 are movably connected to the movable sleeve 18 and the cleaning brush 10 respectively through a hinge shaft structure. During use, starting the cleaning motor 6 can drive the cleaning brush 10 of each layer to rotate. A bearing 19 is provided on the upper part of the movable sleeve 18, and the inner ring of the bearing 19 is fixedly connected to the outer surface of the movable sleeve 18. A lifting cylinder 20 is provided below the motor mounting plate 5. The cylinder body of the lifting cylinder 20 is fixedly connected to the lower surface of the motor mounting plate 5, and its piston rod is connected to an extension rod 21. A secondary rod 22 is provided on the side of the extension rod 21 near the cleaning groove. In this embodiment, three secondary rods 22 are provided. The position of the auxiliary rod 22 corresponds to the bearing 19 of each cleaning groove, and is fixedly connected to the outer ring of each bearing 19 in sequence. In use, the moving sleeve 18 can be moved up and down by controlling the lifting cylinder 20, and the auxiliary rod 22 will not be driven to rotate during the rotation of the moving sleeve 18.

[0027] In this embodiment, the cleaning brush 10 includes an upper brush plate 11. The middle part of the upper surface of the upper brush plate 11 is movably connected to the connecting rod 17 through a hinge shaft structure, and one end of the upper brush plate 11 near the rotating sleeve 16 is movably connected to the rotating sleeve 16 through the hinge shaft structure. By controlling the moving sleeve 18 to move upward through the lifting cylinder 20, the outer end of the cleaning brush 10 can be lifted upward, preventing the cleaning brush 10 from being soaked in water for a long time, which would cause bacterial growth and affect the cleaning effect. A rubber pad 12 is provided below the upper brush plate 11, and a lower brush plate 13 is provided below the rubber pad 12. A set of stepped holes are provided on the upper surface of the upper brush plate 11. In this embodiment, each upper brush plate 11 has two stepped holes on its upper surface for installing bolts 14. After the lower end of the bolt 14 passes through the upper brush plate 11 and the rubber pad 12, it is connected to the upper surface of the lower brush plate 13 by threads. The rubber pad 12 is clamped and fixed by the upper brush plate 11 and the lower brush plate 13. In this embodiment, a bristle structure is fixed to the lower surface of the front lower brush plate 13, and a flexible scraper is fixed to the lower surface of the rear lower brush plate 13. These two structures are used sequentially to clean the inner wall of the cleaning tank, improving the cleaning efficiency of impurities. A spring 15 is installed between the bolt 14 and the stepped hole of the upper brush plate 11. During cleaning, the lower brush plate 13 can agitate and clean the impurities accumulated in the cleaning tank through the rebound force of the rubber pad 12 and the spring 15, improving the cleaning effect of the lower brush plate 13. The outer end of the lower brush plate 13 is bent upwards, with the bend being arc-shaped and possessing a certain degree of elasticity. A side scraper 30 is installed on the outer surface of the bent portion of the lower brush plate 13. In this embodiment, the front side scraper 30 is a bristle structure, and the rear side scraper 30 is a flexible scraper structure. During cleaning, the side scraper 30 can adhere to the inner surface of the cleaning tank through the elasticity of the bend, enhancing the cleaning effect on the inner wall of the cleaning tank.

[0028] A bracket is provided on the front side of the motor mounting plate 5, including a right bracket 23 and a left bracket 24. During installation, the opposing surfaces of the right bracket 23 and the left bracket 24 are fixed to complete the installation of the two brackets and other structures. A lifting motor 25 is located above the right bracket 23, and a lead screw 26 is connected to the shaft of the lifting motor 25. The lower end of the lead screw 26 is rotatably connected to the lower surface of the inner wall of the right bracket 23. A vertical guide rail 27 is located on the right side of the right bracket 23, and a lifting plate 28 is located on the right side of the vertical guide rail 27. The left surface of the lifting plate 28 is slidably connected to the vertical guide rail 27, allowing it to move up and down along the vertical guide rail. A nut 29 is located in the middle of the left surface of the lifting plate 28, which is connected to the lead screw 26. Starting the lifting motor 25 controls the up and down movement of the lifting plate 28. The right surface of the lifting plate 28 is fixedly connected to the motor mounting plate 5. In use, the cleaning mechanisms in the three-layer water tank and each cleaning tank can be moved up and down synchronously by control. In this embodiment, the left support 24 and the remaining structures are symmetrically arranged with the right support 23, and will not be described in detail here.

[0029] In this embodiment, both the water inlet pipe 4 and the sewage outlet pipe 33 adopt a flexible hose structure to avoid obstruction when the water tank 1 moves up and down.

[0030] In this embodiment, when cleaning the water tank, the lifting motors 25 are first activated to move the water tank 1 upwards, preventing the laying hens from drinking the wastewater generated during the cleaning process. Then, the lifting cylinders 20 are controlled to push the piston rods downwards. Once the piston rods reach their limit positions, the cleaning brushes 10 are horizontal. The cleaning motors 6 are then activated, and the cleaning brushes 10 rotate with the shaft 7 to clean impurities in the cleaning tank. After rotating for a certain period, the valves 32 are opened sequentially from bottom to top, allowing wastewater to flow into the lower cleaning tank and then out through the drain pipe. After the wastewater has completely drained, the water inlet pipes 4 are opened for each layer, allowing a small amount of clean water to enter before closing the inlet pipes 4. The clean water then rinses the cleaning tanks and cleaning brushes 10. After the remaining water in the cleaning tank has drained, the cleaning motors 6 are turned off. Then, the lifting cylinders 20 are controlled to pull the piston rods upwards, raising the cleaning brushes 10. After completion, close all valves 32, open the water inlet pipes 4 of each layer to input clean water into the water tank 1, and close the water inlet pipes 4 after the water level exceeds the highest point of the bottom surface of the water tank 1. Then control the lifting motor 25 to lower and reset the water tank 1 to complete the cleaning of the water tank.

[0031] In this invention, each cleaning trough and the top cleaning trough can be connected to the motor mounting plate 5 by adding vertical rods. This design can increase the stability of the connection between the cleaning troughs. This design can be used when the installed cleaning trough and water tank 1 are large.
