[0001] The utility model relates to the technical field of breeding auxiliary equipment, and particularly relates to a flushing device for calves. Background Art

[0002] A calf refers to a young cow during the period from birth to weaning. Most of them are purple-red and red in hair color, accounting for about 80% of the total. Yellow ones are less. The head is square, the nose mirror is flesh-colored, the horns are short, flesh-colored, mostly bent outward or backward slightly; the body is large, all parts develop evenly, the bones are thick, the muscles are plump, the physique is strong, with the characteristics of beef cattle, and the growth and development are fast. It has the characteristics of high beef production and good meat quality, and is suitable for breeding.

[0003] The patent document with the publication number of CN114342823A discloses a cleaning device for cattle breeding, including a mounting frame, connecting rods and a handle. On both sides of one side wall of the mounting frame, the connecting rods are welded. The outer periphery of the end of the connecting rod far away from the mounting frame is slidably connected with a sleeve rod. A connecting spring is arranged in the sleeve rod, and the connecting spring is in contact with the end of the connecting rod far away from the mounting frame and the inner wall of the sleeve rod. By setting the connecting rod, the sleeve rod, the connecting spring, the mounting frame, the connecting block and the handle, when the rotating cleaning tank cleans the cattle body through the brush in the above application document, the cleaning roller can act on the cattle body with a gentle force, making the cattle more comfortable during cleaning. The setting of the connecting snake tube, the connecting solenoid valve and the nozzle enables the device to be conveniently connected to the external water pipeline and makes the nozzle spray water. However, it is more troublesome to use, requires staff to wear it, increases the load of the staff, and is likely to waste water resources if not closed in time after flushing, which is not conducive to daily use. Content of the Utility Model

[0004] The utility model provides a flushing device for calves.

[0005] The technical solution of the present utility model is as follows: A flushing device for calves, including a base. Universal wheels are provided at the bottom of the base. A hydraulic cylinder is provided at the top of the base. The output end of the hydraulic cylinder is fixedly connected to a rear bracket. The front end of the rear bracket is fixedly connected to a front bracket. A rotating shaft penetrates and is rotatably connected to the inner side of the front bracket. A cleaning roller is fixedly connected to the surface of the rotating shaft. A motor is provided outside the front bracket. The motor is fixedly connected to the rotating shaft through its output shaft. A water tank is fixedly connected to the top of the base. A water spraying mechanism is provided at the bottom of the front bracket; the water spraying mechanism includes a pressure chamber and a rotating gear. The pressure chamber is fixedly connected to the bottom of the front bracket through a connecting plate. A water suction pipe penetrates and is fixedly connected to the side of the pressure chamber. A water outlet pipe penetrates and is fixedly connected to the rear end of the pressure chamber. A return spring is provided inside the pressure chamber. A piston plate is slidably connected to the inside of the pressure chamber through a return spring piston. A sliding rod is fixedly connected to the top of the piston plate. The sliding rod penetrates and is slidably connected to the pressure chamber. A toothed rod is fixedly connected to the top of the sliding rod. The rotating gear is fixedly connected to the end of the rotating shaft away from the motor. An anti-rebound mechanism is provided at the top of the piston plate.

[0006] The number of the universal wheels is set to four groups. The cleaning roller protrudes from the front end of the base. The whole device can be pushed and moved through the four groups of universal wheels. When the cleaning roller rotates, it can clean the body of the calf.

[0007] One end of the water suction pipe away from the pressure chamber penetrates and is fixedly connected to the side of the water tank. One end of the water outlet pipe away from the pressure chamber is located above the cleaning roller. The water suction pipe sucks the water in the water tank and sprays it onto the calf through the water outlet pipe.

[0008] Check valves are provided inside both the water suction pipe and the water outlet pipe. The water suction pipe is made of a retractable rubber hose material. The check valves in the water suction pipe and the water outlet pipe can limit the direction of water flow. The retractable rubber hose material of the water suction pipe can be stretched to a certain extent.

[0009] The check valve in the water suction pipe is unidirectionally conductive towards the inside of the pressure chamber. The check valve in the water outlet pipe is unidirectionally conductive towards the pressure chamber. When a negative pressure is formed in the pressure chamber, it will suck the water in the water tank through the water suction pipe. When the water in the pressure chamber is squeezed, the water inside it will be discharged through the water outlet pipe.

[0010] The rotating gear is an incomplete gear, and the teeth on the toothed rod are adapted to the teeth on the rotating gear. When the rotating gear rotates and its teeth mesh with the teeth on the toothed rod, it will drive the toothed rod to move upward.

[0011] The anti-bounce mechanism includes a connecting frame. The bottom of the connecting frame is fixedly connected to the top of the piston plate. A roller is rotatably connected to the inner side of the connecting frame. A groove is formed on the surface of the roller. A telescopic spring is arranged inside the groove. A resistance plate is slidably connected to the inside of the groove through the telescopic spring.

[0012] The surface of the roller is in close contact with the inner wall of the pressure chamber in the initial state. The resistance plate is completely inside the groove in the initial state. When the piston plate moves up and down, the roller will rotate due to the friction with the inner wall of the pressure chamber. At the beginning, the resistance plate being completely inside the groove will not affect the movement of the piston plate.

[0013] The frictional force between the resistance plate and the groove is greater than the gravity of the resistance plate itself, so the resistance plate will not slide out of the groove due to its own gravity.

[0014] One end of the resistance plate away from the telescopic spring is uneven, and the resistance plate is made of rubber material. When the uneven end of the rubber resistance plate contacts the inner wall of the pressure chamber, resistance will be generated.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] 1. By providing a water spraying mechanism, the present utility model enables the whole device to be moved by the setting of universal wheels. The hydraulic cylinder can adjust the height of the cleaning roller to adapt to calves of different body sizes. When the motor is turned on to drive the rotation of the rotating shaft, and the rotating shaft drives the cleaning roller to rotate to clean the body surface of the calf, the water in the water tank will be sucked by the water suction pipe and sprayed onto the calf through the cooperation of components such as the rotating gear, the rack, and the piston plate. When the motor is turned off, the water outlet pipe will also stop spraying water synchronously, which is more convenient to use and not easy to cause waste of water resources.

[0017] 2. By providing an anti-bounce mechanism, when the motor is turned on to drive the rotation of the rotating shaft, the rotating shaft drives the rotation of the rotating gear. When the rotating gear rotates and cooperates with the rack, the sliding rod, and the return spring to make the piston plate move up and down repeatedly in the pressure chamber, the speed of the piston plate moving downward due to the rebound of the return spring can be slowed down through the cooperation of components such as the roller, the resistance plate, and the telescopic spring. This can prevent the inertia caused by the too fast downward movement speed of the piston plate driven by the rebound of the return spring from causing the piston plate to bounce back and collide with the teeth on the rack and the teeth on the rotating gear, which may damage the motor, and further improves the stability of the whole device.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] As Figures 1 to 2As shown in the figure, this embodiment proposes a flushing device for calves, including a base 1. Universal wheels 2 are provided at the bottom of the base 1. A hydraulic cylinder 3 is provided at the top of the base 1. The output end of the hydraulic cylinder 3 is fixedly connected to a rear bracket 4. The front end of the rear bracket 4 is fixedly connected to a front bracket 5. A rotating shaft 6 penetrates and is rotatably connected to the inner side of the front bracket 5. A cleaning roller 7 is fixedly connected to the surface of the rotating shaft 6. The number of the universal wheels 2 is set to four groups. The cleaning roller 7 protrudes from the front end of the base 1. The overall device can be pushed and moved through the four groups of universal wheels 2. When the cleaning roller 7 rotates, it can clean the body of the calf. A motor 8 is provided on the outer side of the front bracket 5. The motor 8 is fixedly connected to the rotating shaft 6 through its output shaft. A water tank 9 is fixedly connected to the top of the base 1. A water spraying mechanism 10 is provided at the bottom of the front bracket 5; the water spraying mechanism 10 includes a pressure chamber 101 and a rotating gear 108. The pressure chamber 101 is fixedly connected to the bottom of the front bracket 5 through a connecting plate. A water suction pipe 102 penetrates and is fixedly connected to the side of the pressure chamber 101. A water outlet pipe 103 penetrates and is fixedly connected to the rear end of the pressure chamber 101. One end of the water suction pipe 102 away from the pressure chamber 101 penetrates and is fixedly connected to the side of the water tank 9. One end of the water outlet pipe 103 away from the pressure chamber 101 is located above the cleaning roller 7. The water suction pipe 102 sucks the water in the water tank 9 and sprays it onto the calf through the water outlet pipe 103. Check valves are provided inside both the water suction pipe 102 and the water outlet pipe 103. The water suction pipe 102 is made of a telescopic rubber hose material. The check valves in the water suction pipe 102 and the water outlet pipe 103 can limit the direction of the water flow. The telescopic rubber hose material of the water suction pipe 102 can be stretched to a certain extent. The check valve in the water suction pipe 102 is unidirectionally conductive towards the inside of the pressure chamber 101, and the check valve in the water outlet pipe 103 is unidirectionally conductive towards the pressure chamber 101. When a negative pressure is formed in the pressure chamber 101, it will suck the water in the water tank 9 through the water suction pipe 102, and when the water in the pressure chamber 101 is squeezed, the water inside it will be discharged through the water outlet pipe 103. A return spring 104 is provided inside the pressure chamber 101. A piston plate 105 is slidably connected to the inside of the pressure chamber 101 through the return spring 104. A sliding rod 106 is fixedly connected to the top of the piston plate 105. The sliding rod 106 penetrates and is slidably connected to the pressure chamber 101. A toothed rod 107 is fixedly connected to the top of the sliding rod 106. The rotating gear 108 is fixedly connected to the end of the rotating shaft 6 away from the motor 8. The rotating gear 108 is an incomplete gear, and the teeth on the toothed rod 107 are adapted to the teeth on the rotating gear 108. When the rotating gear 108 rotates and its teeth mesh with the teeth on the toothed rod 107, it will drive the toothed rod 107 to move upward. An anti-backlash mechanism 11 is provided at the top of the piston plate 105.

[0028] In this embodiment, when it is necessary to clean the body of a calf, the entire device is pushed to a suitable position, and the hydraulic cylinder 3 is activated to drive the rear support 4 to rise or fall to adjust the height of the cleaning roller 7 to adapt to the calf. The water suction pipe 102 made of retractable rubber hose can be stretched to a certain extent. The motor 8 is turned on, and the motor 8 drives the rotating shaft 6 to rotate through its output shaft. The rotation of the rotating shaft 6 drives the cleaning roller 7 to rotate to clean the body of the calf. The rotation of the rotating shaft 6 drives the rotating gear 108 to rotate. When the teeth on the rotating gear 108 mesh with the teeth on the tooth bar 107, it will drive the tooth bar 107 to move upward. The upward movement of the tooth bar 107 drives the slide bar 106 and the piston plate 105 to move upward, and the return spring 104 is stretched. When the piston plate 105 moves upward, a negative pressure will be formed in the pressure chamber 101. When a negative pressure is formed in the pressure chamber 101, water in the water tank 9 will be sucked through the water suction pipe 102. When the rotating gear 108 rotates to the part without teeth disengaging from the tooth bar 107, the return spring 104 rebounds to drive the piston plate 105, the slide bar 106, and the tooth bar 107 to move downward to restore. When the piston plate 105 moves downward to restore, it will squeeze the water in the pressure chamber 101 so that the water in it is discharged through the water outlet pipe 103 and sprayed onto the calf, cooperating with the cleaning roller 7 to clean the calf. When the motor 8 is turned off, the water outlet pipe 103 will also stop spraying water synchronously, which is more convenient to use and not easy to cause waste of water resources.

[0029] Embodiment 2

[0030] As Figures 3 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes an anti-rebound mechanism 11, including a connecting frame 111. The bottom of the connecting frame 111 is fixedly connected to the top of the piston plate 105. A roller 112 is rotatably connected to the inside of the connecting frame 111. A groove 113 is formed on the surface of the roller 112. A telescopic spring 114 is arranged inside the groove 113. A resistance plate 115 is slidably connected to the inside of the groove 113 through the telescopic spring 114. The friction between the resistance plate 115 and the groove 113 is greater than the gravity of the resistance plate 115 itself, and the resistance plate 115 will not slide out of the groove 113 due to its own gravity. The surface of the roller 112 is initially in close contact with the inner wall of the pressure chamber 101. The resistance plate 115 is initially completely inside the groove 113. When the piston plate 105 moves up and down, it will cause the roller 112 to rotate due to friction with the inner wall of the pressure chamber 101. At the beginning, the resistance plate 115 is completely inside the groove 113 and will not affect the movement of the piston plate 105. One end of the resistance plate 115 away from the telescopic spring 114 is uneven, and the resistance plate 115 is made of rubber material. When the uneven end of the rubber material resistance plate 115 contacts the inner wall of the pressure chamber 101, resistance will be generated.

[0031] In this embodiment, when the piston plate 105 moves up and down, the roller 112 will rotate due to the friction with the inner wall of the pressure chamber 101. When the piston plate 105 moves upward, the speed is relatively slow, the rotation speed of the roller 112 is relatively slow, and the resistance plate 115 is completely in the groove 113 and does not affect the movement of the piston plate 105. When the return spring 104 rebounds and drives the piston plate 105 to move downward to restore, the speed is relatively fast. At this time, the rotation speed of the roller 112 is also relatively fast. The centrifugal force generated by the rapid rotation of the roller 112 will throw the resistance plate 115 out of the groove 113 to contact the inner wall of the pressure chamber 101 to generate resistance and slow down the downward movement speed of the piston plate 105, preventing the inertia caused by the too fast downward movement speed of the piston plate 105 driven by the rebound of the return spring 104 from causing bouncing back and forth, resulting in the teeth on the rack 107 colliding with the teeth on the rotating gear 108 and damaging the motor 8, and further improving the stability of the overall device.

[0032] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
