Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to an individualized spraying device for dairy farms. Background Technology

[0002] In addition to maintaining air circulation, dairy farms also need to maintain a certain temperature and humidity. Within the optimal temperature range for dairy cows, they can maintain a constant body temperature through their own regulatory mechanisms, thus keeping their milk production, reproductive performance, and health stable. However, if there are situations such as increased temperature, increased humidity, or reduced air circulation, the cows' body temperature will rise, their breathing and pulse will increase, and their feed intake and milk production will decrease. To mitigate the impact of heat stress on dairy cows, certain heatstroke prevention and cooling measures need to be taken on the dairy farm.

[0003] Currently, the most widely used cooling measures in dairy farms are to use sprinkler and fan systems. When workers clearly observe that the temperature in the dairy farm is rising, they manually start the sprinkler and fan systems to cool the entire dairy farm.

[0004] Due to individual differences among dairy cows, within a certain temperature range, only some cows may experience heat stress while others can produce milk normally. The widespread spraying cooling method on dairy farms not only wastes water resources, but also affects the milk production of cows that are producing milk normally, resulting in poor overall milk production efficiency of the dairy farm. Utility Model Content

[0005] Therefore, this utility model provides an individualized spraying device for dairy farms, which effectively solves the technical problem that the existing full-range spraying cooling method in dairy farms not only wastes water resources, but also affects the milk production of normal milk-producing cows, resulting in poor overall milk production efficiency of dairy farms.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: an individualized sprinkler system for dairy farms, including a slide rail installed on the top of the dairy farm, a slide seat movably installed on the slide rail, a rotating frame rotatably installed at the bottom of the slide seat, a movable seat movably installed inside the rotating frame, and a sprinkler head fixedly installed at the bottom of the movable seat via a connecting shaft.

[0007] The rotating frame is provided with a rotating shaft at its end, and a rotating drive component is connected to the end of the rotating shaft. The rotating drive component can drive the rotating frame to rotate through the rotating shaft to adjust the spray direction of the spray head on the movable seat.

[0008] The rotating frame is equipped with a sliding groove seat for the movable seat to move. The end of the movable seat is connected to a displacement drive component, which can adjust the relative position of the movable seat on the sliding groove seat to adjust the relative distance between the spray head and the individual cow.

[0009] Furthermore, a mounting bracket is installed at the bottom of the slide block, and the rotating bracket is rotatably mounted on the mounting bracket via the rotating shaft;

[0013] A first drive wheel and a second drive wheel are mounted on the column shaft. A tension belt is wound around the first drive wheel, and a connecting belt is wound around the second drive wheel.

[0014] One end of the traction belt is connected to the outer circumference of the first drive wheel, one end of the connecting belt is connected to the outer circumference of the second drive wheel, and the other end is connected to the movable seat;

[0015] The sliding groove seat is closed at the end near the mounting groove seat and has a through groove for the connecting belt to pass through. A compression spring is connected between the sliding groove seat and the movable seat.

[0016] By pulling and releasing the end of the traction belt, the first transmission wheel can be driven to rotate, and the second transmission wheel rotates synchronously and pulls and releases the connecting belt, while simultaneously driving the movable seat to move on the sliding groove seat.

[0017] Furthermore, a power seat is installed inside the rotating frame, and a slider is slidably installed inside the power seat. The end of the traction belt is connected to the slider, and a drive cylinder is installed on the side of the slider. The drive end of the drive cylinder is connected to a push column, and the push column is connected to the slider.

[0018] Furthermore, a flow tube is installed on the power base, one end of the flow tube is connected to a water inlet pipe, the other end is connected to a water injection pipe, and the end of the water injection pipe is connected to the spray head;

[0019] The flow tube includes a main tube and a movable tube, the water inlet pipe is connected to the movable tube, and the water injection pipe is connected to the main tube;

[0020] A connecting cylinder is installed inside the main cylinder, and the end of the movable cylinder is movably disposed inside the connecting cylinder, with the outer wall of the movable cylinder fitting into the inner wall of the connecting cylinder;

[0021] The inner wall of the connecting cylinder is provided with a first water passage elongated hole, and the inner wall of the movable cylinder is provided with a second water passage elongated hole.

[0022] The movable cylinder is connected to a connecting plate, and the end of the connecting plate is connected to the push column. The push column drives the movable cylinder to move and adjusts the relative position of the movable cylinder within the connecting cylinder, thereby adjusting the cross-sectional area of ​​the connection between the second water passage orifice and the first water passage orifice.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] like Figure 2 As shown, this utility model provides an individualized spraying device for dairy farms. The spraying device is installed in each breeding area of ​​the dairy farm and can spray one dairy cow in the breeding area to regulate the temperature of the dairy cow.

[0050] Generally, one or two spray systems are installed in each breeding area. If the breeding area is large, more spray systems are needed.

[0051] In application, it is necessary to first determine the location and temperature of individual dairy cows. When the temperature is abnormal, the position and direction of the spraying equipment are adjusted according to the location information to spray the individual dairy cow. For this purpose, infrared acquisition modules also need to be installed in different breeding areas within the dairy farm.

[0052] Each dairy cow is in motion within its different enclosure. To distinguish individual cows, collars are typically worn around their necks, marked with a number. An infrared sensor module identifies each cow. Specifically, this module includes a far-infrared temperature sensor and an infrared sensor. Both are usually mounted on the square tubing of the collar frame within the dairy farm. The infrared sensor identifies the individual cows' numbers within the enclosure, primarily by recognizing the numbers on their collars. The far-infrared temperature sensor measures the surface temperature of each cow, transmitting the measured temperature to the main controller for recording and storage.

[0053] The measured temperature data of individual dairy cows is compared with the individual temperature threshold set in the main controller. If the temperature exceeds the individual temperature threshold, the spray equipment is activated to cool the individual at a specific point.

[0054] Specifically, the main controller is connected to the variable frequency pump controller, and the variable frequency pump controller is connected to the variable frequency pump.

[0055] The variable frequency water pump is connected to the filter and the water tank in sequence through the water supply pipeline. A diversion pipeline is connected to the water supply pipeline between the variable frequency water pump and the filter. The diversion pipeline is connected to several spray devices through the branch pipeline 10. A solenoid valve is connected between the diversion pipeline and the branch pipeline 10. A water meter is installed on the diversion pipeline. The end of the branch pipeline is connected to the inlet pipe 6 and is connected to the spray device. The main controller is connected to the solenoid valve and controls the water flow through the solenoid valve.

[0056] In addition, a solenoid valve can be installed at the water supply pipeline connected to the variable frequency water pump. The solenoid valve here controls the opening and closing of the water supply pipeline connected to the variable frequency water pump, thereby controlling the start of the corresponding spray equipment.

[0057] Water flows from the water tank into the filter and then into the diversion pipe, and through the corresponding branch pipe 10 to the corresponding spray equipment. In other words, if the temperature of an individual cow in a certain breeding area is abnormal, the corresponding solenoid valve in that breeding area needs to be opened to open the branch water tank, so that the water can reach the spray equipment in the corresponding breeding area to implement spray cooling.

[0058] The temperature data of individual cows collected by far-infrared temperature sensors is converted from analog to digital by the second analog-to-digital conversion module to obtain digital signals. The infrared sensing device determines the individual cow and its position signal through the second analog-to-digital conversion module and transmits it to the main controller. The converted digital signals are processed, the data are compared, and then the main controller sends a control signal to control the spraying equipment to start and spray the target cows at the designated location.

[0059] In this invention, to better adapt to the position of individual dairy cows and improve water utilization, the spraying equipment is configured with an adjustable spray range and spray angle. Specifically, as shown in the figure... Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 11 As shown, a slide rail 1 is installed on the top of the dairy farm. The spraying equipment includes a slide seat 21 that is movably installed on the slide rail 1. A rotating frame 22 is rotatably installed at the bottom of the slide seat 21. A movable seat 23 is movably installed inside the rotating frame 22. A spray head 25 is fixedly installed at the bottom of the movable seat 23 through a connecting shaft 24.

[0060] The rotating frame 22 is provided with a rotating shaft 26 at its end, and a rotating drive 3 is connected to the end of the rotating shaft 26. The rotating drive 3 can drive the rotating frame 22 to rotate through the rotating shaft 26, so as to adjust the spraying direction of the spray head 25 on the movable seat 23.

[0061] The rotating frame 22 is equipped with a sliding groove seat 27 for the movable seat 23 to move. The end of the movable seat 23 is connected to a displacement drive 4. The displacement drive 4 can adjust the relative position of the movable seat 23 on the sliding groove seat 27 to adjust the relative distance between the spray head 25 and the individual cow.

[0062] In this invention, the spraying range of the spray head 25 relative to the individual cow is adjusted by adjusting the relative distance between the spray head 25 and the individual cow, so that the water at the spray point acts fully on the individual cow, enhancing the spraying cooling effect, avoiding the impact on the milk production process of other individual cows, and improving the overall milk production efficiency of the dairy farm.

[0063] To adjust the spray direction of the spray head 25, the rotating frame 22 in this invention is rotatable, such as... Figure 6 As shown, a mounting bracket 28 is installed at the bottom of the slide 21, and a rotating bracket 22 is rotatably mounted on the mounting bracket 28 via a rotating shaft 26; the rotating drive component 3 includes a first drive motor 31 mounted on the mounting bracket 28; the drive end of the first drive motor 31 is connected to the rotating shaft 26.

[0064] Driven by the first drive motor 31, the rotating frame 22 can rotate relative to the mounting frame 28 through the rotating shaft 26, and rotate around the rotating shaft 26, thereby driving the spray head 25 to rotate synchronously and adjust its spraying direction.

[0065] In practical applications, such as Figure 1 As shown (the ellipsoid in the figure represents an individual cow, and the dashed line represents the spray range of the sprinkler head), the spray range of the sprinkler head 25 does not completely cover a particular cow. Some water may pass over the cow and fall to the ground or spray onto other cows. This results in low water resource utilization and may affect other cows with normal body temperature. Therefore, this invention provides a sprinkler head 25 whose relative position can be adjusted along the spray direction. When the spray range is too large, the distance between the sprinkler head 25 and the target cow can be reduced, thus shrinking the spray range of the sprinkler head 25 to cover the target cow, reducing water waste and improving water utilization.

[0066] Specifically, a displacement drive component 4 is used to adjust the relative distance between the spray head 25 and the individual cow. The displacement drive component 4 of this invention adopts the following preferred embodiment, such as... Figure 7 , Figure 8 , Figure 9 and Figure 11As shown, the displacement drive component 4 includes a mounting slot 41 installed in the rotating frame 22 and a column shaft 42 rotatably disposed in the mounting slot 41;

[0067] A first drive wheel 43 and a second drive wheel 44 are mounted on the column shaft 42. A tension belt 45 is wound on the first drive wheel 43, and a connecting belt 46 is wound on the second drive wheel 44.

[0068] One end of the traction belt 45 is connected to the outer periphery of the first transmission wheel 43, one end of the connecting belt 46 is connected to the outer periphery of the second transmission wheel 44, and the other end is connected to the movable seat 23; the end of the sliding groove seat 27 near the mounting groove seat 41 is closed, and a through groove 47 for the connecting belt 46 to pass through is provided; a compression spring 48 is connected between the sliding groove seat 27 and the movable seat 23.

[0069] By pulling and releasing the end of the pull belt 45, the first transmission wheel 43 can be driven to rotate, and the second transmission wheel 44 rotates synchronously and pulls and releases the connecting belt 46, while simultaneously driving the movable seat 23 to move on the sliding groove seat 27.

[0070] The compression spring 48 is always in a compressed state. Under the elastic force of the compression spring 48, the movable seat 23 is always subjected to downward compression force and also to the tension force of the connecting belt 46. When the connecting belt 46 moves upward, the movable seat 23 moves upward accordingly. When the connecting belt 46 moves downward, the movable seat 23 also moves downward synchronously under the compression force. The connecting belt 46 is always in a straightened state.

[0071] The surfaces of the tension belt 45 and the connecting belt 46 are in contact with the corresponding wheel surfaces. To prevent the connecting belt 46 from contacting the groove opening of the through groove 47, a support wheel can be installed inside the rotating frame 22, located directly below the second transmission wheel 44. The connecting belt 46 passes through the second transmission wheel 44 and the support wheel, extends downward, and connects to the movable seat 23. This can prevent the connecting belt 46 from interfering with the groove opening and generating friction that prevents the connecting belt 46 from moving.

[0072] like Figure 10 As shown, a power seat 49 is installed inside the rotating frame 22, and a slider 410 is slidably installed inside the power seat 49. The end of the traction belt 45 is connected to the slider 410. A drive cylinder 411 is installed on the side of the slider 410. A push column 412 is connected to the drive end of the drive cylinder 411. The push column 412 is connected to the slider 410.

[0073] Driven by the cylinder 411, the slider 410 moves on the power seat 49. Under the force of the compression spring 48, the connecting belt 46 is always under downward tension. The second transmission wheel 44 also tends to rotate clockwise under the tension of the connecting belt 46. When the slider 410 is stationary, the traction belt 45 on the first transmission wheel 43 is under counterclockwise tension, while the second transmission wheel 44 is under clockwise tension. Under tension in different directions, the first transmission wheel 43 and the second transmission wheel 44 remain stationary. When the slider 410 moves closer to the first transmission wheel 43, the first transmission wheel 43 and the second transmission wheel 44 rotate clockwise under the tension of the connecting belt 46, allowing the movable seat 23 to move downward a distance along the sliding groove seat 27, driving the spray head 25 forward a distance along the spray direction. After adjustment, the spray range of the spray head 25 completely covers the individual cow.

[0074] In practical applications, as the spray head 25 approaches the individual cow, the water impact force on the cow's body surface also increases. If the cow notices and avoids the area due to the significant increase in water pressure, cooling cannot be successfully completed. To address this, the present invention incorporates the following design: Figure 12 As shown, a flow tube 5 is installed on the power base 49. One end of the flow tube 5 is connected to a water inlet pipe 6, and the other end is connected to a water injection pipe 7. The end of the water injection pipe 7 is connected to a spray head 25.

[0075] The flow tube 5 includes a main tube 51 and a movable tube 52. The water inlet pipe 6 is connected to the movable tube 52, and the water injection pipe 7 is connected to the main tube 51.

[0076] A connecting cylinder 53 is installed inside the main cylinder 51, and the end of the movable cylinder 52 is movably disposed inside the connecting cylinder 53, with the outer wall of the movable cylinder 52 fitting with the inner wall of the connecting cylinder 53;

[0077] A first water passage elongated hole 54 is provided on the inner wall of the connecting cylinder 53, and a second water passage elongated hole 55 is provided on the inner wall of the movable cylinder 52. Water enters the movable cylinder 52 through the water inlet pipe 6, and passes through the second water passage elongated hole 55 and the first water passage elongated hole 54 into the main cylinder 51, and then is discharged to the spray head 25 through the water injection pipe 7.

[0078] The movable cylinder 52 is connected to a connecting plate 56. The end of the connecting plate 56 is connected to a pusher 412. The pusher 412 drives the movable cylinder 52 to move and adjust the relative position of the movable cylinder 52 in the connecting cylinder 53, so as to adjust the communication cross section between the second water passage long hole 55 and the first water passage long hole 54.

[0079] When the drive cylinder 411 pushes the slider 410 toward the first transmission wheel 43, it also drives the connecting plate 56 toward the first transmission wheel 43, and simultaneously drives the movable cylinder 52 into the connecting cylinder 53. In the initial state, the second water passage hole 55 and the first water passage hole 54 overlap, and the cross-sectional area between the second water passage hole 55 and the first water passage hole 54 is the largest. After the movement, the cross-sectional area between the second water passage hole 55 and the first water passage hole 54 becomes smaller, and the water flow rate between the second water passage hole 55 and the first water passage hole 54 per unit time becomes smaller. This also makes the water volume at the spray head 25 smaller and the water pressure lower.

[0080] Therefore, when the spray head 25 approaches the individual cow along its own spray direction, the spray volume is reduced, which can avoid excessive water pressure from impacting the individual cow and prevent the individual cow from being startled and avoiding it.

[0081] In this invention, the position of the sprinkler head 25 in the breeding area is also adjustable, in addition to its adjustable spray direction. Specifically, for example... Figure 4 As shown, a second drive motor 8 is mounted on the slide block 21, and a gear 9 is connected to the drive end of the second drive motor 8. A rack is provided at the bottom of the slide rail 1, and the gear 9 meshes with the rack.

[0082] The second drive motor 8 drives the gear 9 to rotate, thereby driving the gear 9 and the rack to move relative to each other, so that the gear 9 and the slide 21 move relative to the rack.

[0083] The slide 21 can move the spray head 25 along the slide rail 1, so that the spray head 25 can adjust the spray position to spray individual cows in various locations within the breeding area.

[0084] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
