Description

Technical Field

[0001] This utility model relates to the field of cattle breeding technology, specifically a cattle shed ventilation device. Background Technology

[0002] The existing large cattle sheds and cattle houses use top-mounted fans for ventilation. The fans are mostly fixed to the top beams of the cattle house by brackets or ceiling, and are evenly distributed according to the area of ​​the cattle house. In cattle sheds, cattle have a natural tendency to huddle together. However, the position and coverage of the top fans are predetermined. When the cattle huddle together in a certain area, the density of cattle in that area will increase sharply, but the number of top fans will not increase accordingly. Moreover, the airflow will be blocked by the dense cattle bodies. Faced with the height difference between large and small cattle or the two states of cattle standing and lying down, the effective airflow area of ​​the fans is difficult to cover. Furthermore, during the high temperatures of summer, the top fans can only achieve air circulation, with limited cooling effect. In areas where cattle are huddled together, the lack of ventilation exacerbates stress responses, affecting not only feed intake and production performance but also potentially causing acute health problems. Utility Model Content

[0003] The purpose of this invention is to provide a ventilation device for cattle sheds to address the problems in the background art where, during the sowing process, cattle naturally huddle together in the shed, but the position and coverage of the top fans are preset. When the cattle huddle together in a certain area, the density of cattle in that area increases sharply, but the number of top fans does not increase accordingly, and the airflow is blocked by the dense cattle bodies. Given the height difference between large and small cattle or the two states of cattle standing and lying down, the effective airflow area of ​​the fans is difficult to cover. Moreover, in the high temperatures of summer, the top fans can only achieve air circulation, with limited cooling effect. In the huddled area, the insufficient ventilation exacerbates the stress response of the cattle, which not only affects feed intake and production performance, but may also cause acute health problems.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ventilation device for cattle sheds, including a fan, a lifting component inside the movable box, and a humidifying component inside the movable box; The lifting assembly includes a reciprocating lead screw, which is rotatably embedded inside the movable box. The reciprocating lead screw is connected to a movable plate through a ball nut pair. The fan is fixedly connected to the top of the outer surface of the movable plate. A limit rod is fixedly connected to the bottom of the inner wall of the movable box. The movable plate is slidably sleeved on the outer surface of the limit rod in a vertical direction. The humidification assembly includes a moisture-absorbing plate, and a plurality of connecting rods are fixedly connected to one side of the outer surface of the moisture-absorbing plate. The ends of the plurality of connecting rods away from the moisture-absorbing plate are all fixedly connected to one side of the outer surface of the fan. An air cylinder is fixedly connected to the top of the inner wall of the movable box, and a push rod is fixedly connected to the bottom of the outer surface of the movable plate. The push rod is horizontally slidably embedded inside the air cylinder.

[0005] Preferably, a support tube is fixedly connected to one side of the outer surface of the movable plate, and a spray head is fixedly connected to the end of the support tube away from the movable plate.

[0006] Preferably, a liquid storage tank is fixedly connected to one side of the inner wall of the mobile box, and an inlet pipe is fixedly connected to the top of the outer surface of the liquid storage tank, with a screw plug cap threaded onto the outer surface of the inlet pipe.

[0007] Preferably, the liquid storage tank is provided with a liquid delivery pipe inside, and the end of the liquid delivery pipe away from the liquid storage tank is located inside the support pipe.

[0008] Preferably, a piston is fixedly connected to one side of the outer surface of the push rod, and the piston is slidably embedded inside the air cylinder in a vertical direction. An air inlet pipe is fixedly connected to the outer surface of the air cylinder, and a first one-way valve is provided inside the air inlet pipe.

[0009] Preferably, an air supply pipe is fixedly connected to the outer surface of the air cylinder, and the end of the air supply pipe away from the air cylinder is located inside the air cylinder, and a second one-way valve is provided inside the air supply pipe.

[0010] Preferably, a drive motor is fixedly connected to the top of the outer surface of the mobile box, and the output shaft of the drive motor is fixedly connected to a reciprocating lead screw, and multiple casters are fixedly connected to the bottom of the outer surface of the mobile box.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are: First, with this invention, workers use casters to push the mobile box to the location where the cattle are gathered. By turning on the fan, the cattle are cooled down. By turning on the drive motor on the top of the mobile box, the drive motor drives the reciprocating screw to rotate, which in turn moves the moving plate. The movement of the moving plate causes the fan to move up and down, thus blowing air to cool the cattle. This avoids the problem of the fan only blowing on the large cattle and not the small cattle due to differences in the standing and lying positions of the cattle, or the height difference between large and small cattle. It also ensures that the cattle lying down can also be exposed to the airflow, avoiding the problem of uneven standing and lying positions of the cattle.

[0012] Secondly, in summer, this invention only blows hot air during ventilation. Workers unscrew the cap and add water or a concentrated cooling agent to the storage tank through the inlet pipe. As the fan reciprocates, a moving plate drives a push rod and piston to slide inside the cylinder. When the piston slides inside the cylinder, gas is drawn in through the inlet pipe. Then, when the piston compresses the gas inside the cylinder, the gas enters the storage tank through the delivery pipe. Water inside the storage tank is then transported to the support pipe through the delivery pipe and subsequently sprayed through the spray nozzle. The surface of the moisture-absorbing board is made of porous clay, which is fired at high temperature. The porous clay board has a large number of honeycomb-like micropores inside, which have strong and uniform moisture absorption capacity. At the same time, the micropores can filter some of the dust in the cowshed. By humidifying the moisture-absorbing board, the fan blows out moist air. The moist air absorbs heat through the evaporation of water in the air, which can lower the perceived temperature in the blowing area, improve cooling efficiency, and reduce the heat stress response of the cattle, such as reducing open-mouth breathing, lowering heart rate, and avoiding a decrease in feed intake and milk production due to high temperature.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4A ventilation device for cattle sheds includes a fan 2, a lifting assembly inside a movable box 1, and a humidifying assembly inside the movable box 1. The lifting assembly includes a reciprocating screw 3, which is rotatably embedded inside the movable box 1. The reciprocating screw 3 is connected to a movable plate 201 through a ball nut pair. The fan 2 is fixedly connected to the top of the outer surface of the movable plate 201. A limit rod 301 is fixedly connected to the bottom of the inner wall of the movable box 1. The movable plate 201 is slidably sleeved on the outer surface of the limit rod 301 in a vertical direction. The humidification assembly includes a moisture-absorbing plate 4, and a plurality of connecting rods 202 are fixedly connected to one side of the outer surface of the moisture-absorbing plate 4. The ends of the plurality of connecting rods 202 away from the moisture-absorbing plate 4 are all fixedly connected to one side of the outer surface of the fan 2. An air cylinder 7 is fixedly connected to the top of the inner wall of the movable box 1. A push rod 8 is fixedly connected to the bottom of the outer surface of the movable plate 201, and the push rod 8 is horizontally slidably embedded inside the air cylinder 7.

[0017] Using the above technical solution, workers push the mobile box 1 to the location where the cattle are gathered using the casters 101. By turning on the fan 2, the cattle are cooled down. By turning on the drive motor 9 on the top of the mobile box 1, the drive motor 9 drives the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 drives the moving plate 201 to move. The movement of the moving plate 201 drives the fan 2 to move up and down. The up and down movement of the fan 2 blows air to cool down the cattle. This avoids the problem of the fan 2 only blowing on the large cattle and not the small cattle due to differences in the standing and lying positions of the cattle, and the height difference between the large and small cattle. It also ensures that the cattle lying down can also be exposed to the airflow, avoiding the problem of uneven standing and lying positions of the cattle.

[0018] Through the above technical solution, in summer, simple ventilation blows hot air. Workers unscrew the cap 602 and add clean water or a cooling agent to the storage tank 6 through the inlet pipe 601. As the fan 2 reciprocates, the moving plate 201 drives the push rod 8 and piston 801 to slide inside the air cylinder 7. When the piston 801 slides inside the air cylinder 7, gas is drawn into the air cylinder 7 through the inlet pipe 701. Subsequently, when the piston 801 compresses the gas inside the air cylinder 7, the gas enters the storage tank 6 through the air delivery pipe 703. Water inside the storage tank 6 is transported through the liquid delivery pipe 502. The liquid is directed into the support pipe 501 and then sprayed onto the surface of the moisture-absorbing plate 4 through the spray nozzle 5. The moisture-absorbing plate 4 is a porous clay plate, which is made of clay fired at high temperature. It has a large number of honeycomb-shaped micropores inside, which have strong moisture absorption capacity and uniform speed. At the same time, the micropores can filter some of the dust in the cowshed. By humidifying the moisture-absorbing plate 4, the fan 2 blows out humid air. The humid air absorbs heat through the evaporation of water in the air, which can reduce the perceived temperature of the blowing area, improve the cooling efficiency, and reduce the heat stress response of the cattle, such as reducing open-mouth breathing, lowering heart rate, and avoiding a decrease in feed intake and milk production due to high temperature.

[0019] Specifically, a support tube 501 is fixedly connected to one side of the outer surface of the movable plate 201, and a spray head 5 is fixedly connected to the end of the support tube 501 away from the movable plate 201.

[0020] The above technical solution involves spraying water onto the surface of the moisture-absorbing plate 4 through the spray head 5.

[0021] Specifically, a liquid storage tank 6 is fixedly connected to one side of the inner wall of the mobile box 1, and an inlet pipe 601 is fixedly connected to the top of the outer surface of the liquid storage tank 6. A screw plug 602 is threaded on the outer surface of the inlet pipe 601.

[0022] Using the above technical solution, the staff unscrews the plug cap 602 and adds clean water or a cooling agent of a certain concentration into the liquid storage tank 6 through the liquid inlet pipe 601.

[0023] Specifically, the liquid storage tank 6 is equipped with a liquid delivery pipe 502, and the end of the liquid delivery pipe 502 away from the liquid storage tank 6 is located inside the support pipe 501.

[0024] Through the above technical solution, the water inside the storage tank 6 is transported to the support pipe 501 through the liquid delivery pipe 502.

[0025] Specifically, a piston 801 is fixedly connected to one side of the outer surface of the push rod 8, and the piston 801 is slidably embedded in the inside of the air cylinder 7 in a vertical direction. An air inlet pipe 701 is fixedly connected to the outer surface of the air cylinder 7, and a first one-way valve 702 is provided inside the air inlet pipe 701.

[0026] With the above technical solution, when the piston 801 slides inside the air cylinder 7, gas is drawn into the air cylinder 7 through the air inlet pipe 701.

[0027] Specifically, an air supply pipe 703 is fixedly connected to the outer surface of the air cylinder 7, and the end of the air supply pipe 703 away from the air cylinder 7 is located inside the air cylinder 7. A second one-way valve 704 is installed inside the air supply pipe 703.

[0028] With the above technical solution, when the piston 801 compresses the gas inside the air cylinder 7, the gas enters the liquid storage tank 6 through the air delivery pipe 703.

[0029] Specifically, a drive motor 9 is fixedly connected to the top of the outer surface of the movable box 1, and the output shaft of the drive motor 9 is fixedly connected to the reciprocating lead screw 3. Multiple casters 101 are fixedly connected to the bottom of the outer surface of the movable box 1.

[0030] Using the above technical solution, the staff pushes the mobile box 1 to the location where the cattle gather using the casters 101. The drive motor 9 drives the reciprocating screw 3 to rotate, which in turn drives the moving plate 201 to move. The movement of the moving plate 201 drives the fan 2 to move up and down reciprocally.

[0031] In use, the staff pushes the mobile box 1 to the location where the cattle are gathered using the casters 101. The fan 2 is turned on to cool the cattle. The drive motor 9 on the top of the mobile box 1 is turned on, which drives the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 drives the moving plate 201 to move. The movement of the moving plate 201 drives the fan 2 to move up and down. The up and down movement of the fan 2 blows air to cool the cattle. This avoids the problem of the fan 2 only blowing on the large cattle and not the small cattle due to the difference in the standing and lying positions of the cattle, and the height difference between the large cattle and the small cattle. It also ensures that the cattle lying down can also be exposed to the airflow, and avoids the problem of uneven standing and lying of the cattle. In summer, ventilation only blows hot air. Workers unscrew the cap 602 and add water or a cooling agent to the storage tank 6 through the inlet pipe 601. As the fan 2 reciprocates, the moving plate 201 drives the push rod 8 and piston 801 to slide inside the air cylinder 7. When the piston 801 slides inside the air cylinder 7, gas is drawn into the air cylinder 7 through the inlet pipe 701. Subsequently, when the piston 801 compresses the gas inside the air cylinder 7, the gas enters the storage tank 6 through the delivery pipe 703. Water inside the storage tank 6 is transported to the support pipe 5 through the delivery pipe 502. Within 01, the liquid is then sprayed onto the surface of the moisture-absorbing plate 4 through the spray head 5. The moisture-absorbing plate 4 is a porous clay plate, which is made of clay fired at high temperature. It has a large number of honeycomb-shaped micropores inside, which have strong moisture absorption capacity and uniform speed. At the same time, the micropores can filter some of the dust in the cowshed. By humidifying the moisture-absorbing plate 4, the fan 2 blows out humid air. The humid air absorbs heat through the evaporation of water in the air, which can reduce the perceived temperature of the blowing area, improve the cooling efficiency, and reduce the heat stress response of the cattle, such as reducing open-mouth breathing, lowering heart rate, and avoiding a decrease in feed intake and milk production due to high temperature.
