[0025] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0026] See also Figures 1 to 4The present invention provides a stacked closed three-dimensional breeding equipment, including a breeding room 1, a plurality of chicken cages 8 and a controller 16. A water storage chamber 5 and a breeding chamber 3 are respectively arranged on the upper and lower sides of the breeding room 1. The water storage chamber 5 is used to store clean water. A water inlet channel 14 is vertically arranged in the right wall of the breeding chamber 3. The upper end of the water inlet channel 14 is connected to the bottom of the water storage chamber 5 through an electromagnetic valve 1 33. A plurality of water tanks 25 are arranged from top to bottom in the breeding chamber 3. A liquid level gauge 1 15 and a liquid level gauge 2 31 are fixedly arranged on the inner side walls of the water tank 25 from top to bottom. The right end of the water tank 25 is connected to the water inlet channel 14 through an electromagnetic valve 2 12. The left end of the water tank 25 is connected to the outside of the breeding chamber 3 through an electromagnetic valve 3 2. The bottom of the chicken cage 8 is an open rectangular structure. The lower side of the chicken cage 8 is fixedly connected to the upper side of the water tank 25. Specifically, the chicken cage The front and rear side walls of the chicken cage 8 are respectively fixedly connected to the front and rear inner walls of the water tank 25. The bottom of the chicken cage 8 is connected to the bottom net 11 through an elastic mechanism. The chicken cage 8 and the bottom net 11 are both made of hard mesh materials. The chickens are raised in the sealed space formed by the chicken cage 8 and the bottom net 11. The bottom net 11 is located in the water tank 25 and has a preset distance from the bottom of the water tank 25. The bottom net 11 is located between the liquid level gauge 15 and the liquid level gauge 2 31. Since the bottom net 11 is connected to the chicken cage 8 through an elastic mechanism, the chickens will walk on the bottom net 11 during the breeding process to make the bottom net 11 vibrate, which is conducive to the excrement falling from the bottom net 11 into the water tank 25, and can avoid excessive excrement adhering to the bottom net 11. The controller 16 is electrically connected to the solenoid valve 1 33, the solenoid valve 2 12, the solenoid valve 3 2, the liquid level gauge 15 and the liquid level gauge 2 31;

[0027] When it is necessary to clean the excrement in the water tank 25, the controller 16 controls the solenoid valve 1 33 to open, and the controller 16 controls the solenoid valve 3 2 to close, and the water in the water storage chamber 5 flows into the water inlet channel 14, and the water in the water inlet channel 14 flows into the water tank 25 through the solenoid valve 2 12. When the water level in the water tank 25 rises to the position of the liquid level gauge 2 31, the water level in the water tank 25 is below the bottom net 11, and the controller 16 controls the solenoid valve 2 12 to close, and this state is maintained for a preset time (10 minutes to 15 minutes), which is good for the water. After the excrement in the tank 25 is soaked to soften it, the controller 16 controls the solenoid valve 3 2 to open, so that the water in the tank 25 discharges the excrement outside the breeding room 1 through the solenoid valve 3 2. After the water in the tank 25 is drained, the controller 16 controls the solenoid valve 2 12 to open again, and controls the solenoid valve 3 2 to close, so that the water in the water inlet channel 14 flows into the tank 25 through the solenoid valve 2 12 again, so that the tank 25 is soaked again. In this way, the excrement in the tank 25 is cleaned by soaking and draining for multiple times (at least 10 times);

[0028] After cleaning the excrement in the water tank 25, the controller 16 controls the solenoid valve three 2 to close, and the water in the water storage chamber 5 flows into the water inlet channel 14. The water in the water inlet channel 14 flows into the water tank 25 through the solenoid valve two 12. When the water level in the water tank 25 rises to the position of the liquid level gauge one 15, the water level in the water tank 25 is located at a preset distance above the bottom net 11 (preferably 1.5 cm higher than the bottom net), and the controller 16 controls the solenoid valve two 12 to close, and this state is maintained for a preset time (10 minutes to 15 minutes). After the excrement attached to the bottom net 11 is soaked to soften it, the excrement attached to the water tank 25 can be further soaked in this process. It is beneficial to improve the cleaning effect of the bottom net 11. The controller 16 controls the electromagnetic valve 3 2 to open, so that the water in the water tank 25 discharges the bottom net 11 and the excrement in the water tank 25 out of the breeding room 1 through the electromagnetic valve 3 2. After the water in the water tank 25 is drained, the controller 16 controls the electromagnetic valve 2 12 to open and controls the electromagnetic valve 3 2 to close, so that the water in the water inlet channel 14 flows into the water tank 25 through the electromagnetic valve 2 12 again, so that the water in the water tank 25 is again soaked in the bottom net 11. In this way, the excrement on the bottom net 11 is cleaned by multiple soaking and drainage (at least 10 times), and the cleaning effect is good. The use of alternating soaking and flushing can also achieve the effect of saving water.

[0029] In addition, during the soaking process of the bottom net 11, since the water in the water tank 25 covers the bottom net 11, the chicken feet will be immersed in the water, and the excrement on the chicken claws will be soaked and cleaned, and during the drainage process of the water tank 25, the chicken claws can be rinsed, which can improve the cleanliness of the chicken claws; and during the soaking process, the chicken will walk on the bottom net 11 to make the bottom net 11 vibrate in the water, which can cause the excrement adhered to the bottom net 11 to fall into the water, which is beneficial to improve the cleaning effect of the bottom net 11.

[0030] Preferably, the elastic mechanism includes a plurality of upper seats 30 fixed at intervals at the bottom edge of the chicken cage 8 and a plurality of lower seats 26 fixed at intervals at the edge of the bottom net 11, a slide bar 28 is fixedly provided on the lower surface of the upper seat 30, the slide bar 28 is slidably passed through the lower seat 26, a stopper 29 is fixedly provided at the lower end of the slide bar 28, a spring 27 is sleeved on the lower side of the slide bar 28, and the spring 27 abuts between the lower surface of the lower seat 26 and the upper surface of the stopper 29; when the chicken walks on the bottom net 11, the bottom net 11 will drive the lower seat 26 to slide on the slide bar 28, and the lower seat 26 and the stopper 29 will compress the spring, causing the bottom net 11 to vibrate vertically at the bottom of the chicken cage 8.

[0031] Preferably, a guide rod 9 and a reciprocating screw rod 10 are rotatably penetrated on the upper part of the chicken cage 8, a screw rod seat 18 is sleeved on the guide rod 9 and the reciprocating screw rod 10, the reciprocating screw rod 10 is connected to a motor 17, the motor 17 is arranged on the side wall of the chicken cage 8, a vertical rod 22 is connected to the lower surface of the screw rod seat 18, the vertical rod 22 is connected to a cross rod 23, the cross rod 23 is located near the bottom of the bottom net 11, and specifically the distance between the cross rod 23 and the bottom net 11 is 2-4 cm;

[0032] During the soaking process of the bottom net 11, the motor 17 is used to drive the reciprocating screw 10 to rotate in the chicken cage 8. Under the action of the guide rod 9 limiting the screw seat 18 to follow the reciprocating screw 10 to rotate, the reciprocating screw 10 drives the screw seat 18 to move slowly left and right along the length direction of the chicken cage 8. The screw seat 18 drives the cross bar 23 to reciprocate above the bottom net 11 through the vertical rod 22. In this way, the cross bar 23 will touch the chicken's claws, driving the chicken to walk on the bottom net 11 or the chicken will jump over the cross bar 23, making the bottom net 11 vibrate more violently in the water, which can cause the attachments on the bottom net 11 to fall off in the water, which is beneficial to improving the cleaning effect of the bottom net 11, and when the chicken jumps over the cross bar 23, the chicken's claws will quickly leave and then enter the water, which is beneficial to the excrement attached to the chicken's claws falling off in the water, which is beneficial to the cleaning effect of the chicken's claws.

[0033] Preferably, a ball head 19 is provided at the upper end of the vertical rod 22, and a ball bowl is provided on the lower surface of the screw seat 18, and the ball head 19 is arranged in the ball bowl. A retaining ring 21 is fixedly provided on the upper side of the vertical rod 22, and a spring 20 is sleeved on the upper side of the vertical rod 22. The spring 20 abuts between the lower surface of the screw seat 18 and the upper surface of the retaining ring 21. The resilience of the spring 20 can push the vertical rod 22 downward through the retaining ring 21, so that the vertical rod 22 has the ability to restore to a vertical state. When the vertical rod 22 drives the cross bar 23 to touch the chicken claw, the cross bar 23 will drive the ball head 19 to rotate in the ball bowl through the vertical rod 22 and compress the spring 20, so that the vertical rod 22 and the screw seat 18 are elastically connected, which can prevent the cross bar 23 from pushing the chicken claw hard and causing damage to it.

[0034] Preferably, the cross bar 23 is rotatably connected to the vertical bar 22, and bristles 24 are evenly provided on the outer peripheral surface of the cross bar 23. The lower ends of the bristles 24 are penetrated on the bottom net 11, so that when the vertical bar 22 drives the cross bar 23 to move back and forth, the bristles 24 will continuously insert into the bottom net 11 and drive the cross bar 23 to rotate on the vertical bar 22. In this way, the bristles 24 will clean the bottom net 11, which is beneficial to improving the cleaning effect of the bottom net 11, and when the chicken jumps over the cross bar 23, the bristles 24 will brush the chicken claws, which is beneficial to the cleaning effect of the chicken claws.

[0035] Preferably, an electric heater 32 is provided in the water inlet channel 14 near the solenoid valve 33. When water flows through the electric heater 32, the electric heater 32 can heat the water, thereby preventing the water temperature from being too low, which may cause the chickens to catch cold and become sick when the bottom net 11 is soaked.

[0036] Preferably, a temperature sensor 13 is provided in the breeding chamber 3, a processing box 40 is fixedly provided on the outer wall of the breeding room 1, an air inlet pipe 36 and a fan 41 are respectively provided at the top and bottom of the processing box 40, an exhaust pipe 42 is connected to the exhaust end of the fan 41, the exhaust pipe 42 is connected to the water inlet channel 14 through a one-way valve 43, and the connection point is located above the uppermost solenoid valve 2 12, the function of the one-way valve 43 is to prevent the water in the water inlet channel 14 from flowing into the exhaust pipe 42, an air filter layer 37, a PTC heater 38 and an evaporator 39 are respectively provided in the processing box 40 from top to bottom, and the controller 16 is electrically connected to the temperature sensor 13, the electric heater 32, the PTC heater 38 and the evaporator 39;

[0037] During the breeding ventilation process or after the cleaning and excretion is completed, the controller 16 controls the solenoid valve 1 33 to close, controls the solenoid valve 2 12 to open, and controls the solenoid valve 3 2 to open, so that the water in the water tank 25 and the water inlet channel 14 is discharged. The fan 41 is used to make the external air flow into the processing box 40 through the air inlet pipe 36. The harmful substances are filtered out when the air passes through the air filter layer 37. The air then passes through the PTC heater 38. When the temperature sensor 13 detects that the temperature in the breeding chamber 3 is lower than the preset lower limit (23°C), the controller 16 controls the PTC heater 38 to heat the air. When the air passes through the evaporator 39 again, when the temperature sensor 13 detects that the temperature in the breeding chamber 3 is higher than the preset upper limit (27°C), the controller 16 controls the evaporator 39 to cool the air, so that the temperature in the breeding chamber 3 can be maintained at 23°C to 27°C suitable for the growth of chickens; the air in the processing box 40 is transported to the exhaust pipe 42 through the fan 41, flows into the water inlet channel 14 through the one-way valve 43 for diversion, and the air flows into the water tank 25 through the corresponding electromagnetic valves 2 12, and is then discharged by the electromagnetic valve 3 2.
