Description

Technical Field

[0001] The present invention relates to the field of breeding, and particularly to a digital yak breeding system. Background Art

[0002] China accounts for more than 90% of the world's yak breeding population and is the largest country in yak breeding. With the continuous improvement of the intensification level of yak breeding, it has also brought huge challenges to yak breeding problems.

[0003] Currently, during the yak breeding process, the yak warm shed generally includes a bottom surface, a wall, and a roof. Air inlets are opened at positions close to the ground at the lower ends of the south-facing and north-facing walls, and air outlets are opened at the upper ends. Most of the existing yak breeding requires manual operation. For example, the administrator needs to manually spray the cowshed, which is not only inefficient but also consumes a lot of manpower and material resources.

[0004] Secondly, the existing breeding system cannot quickly adjust the cowshed according to the changes in the cowshed environment, and the breeding method is not scientific and convenient enough.

[0005] The existing yak monitoring technologies mainly include: achieving real-time monitoring of the health of yaks through sensing technology to realize epidemic warning and productivity prediction; however, the existing health monitoring is based on physiological data, usually only body temperature data, with a single judgment basis and one-sided judgment results. How to more comprehensively monitor the health status of the yak herd with the help of intelligent and automated data collection and computer-aided analysis is a technical problem that needs to be urgently solved in this field. Summary of the Invention

[0006] An object of the present invention is to provide a digital yak breeding system, which adopts intelligent management equipment to realize a standardized, scientific, and intelligent management mode for the breeding park.

[0007] This object is achieved by the following technical solutions: This system includes a control terminal, a spraying device, a rolling curtain device, a fan device, and a first environment monitoring device arranged in the cowshed, and a second environment monitoring device arranged outside the cowshed. The control terminal is used to receive the monitoring data of the first environment monitoring device and the second environment monitoring device, and control the spraying device, the rolling curtain device, and the fan device to work according to the monitoring data. The first environment monitoring device includes a temperature sensor and a humidity sensor. The control terminal controls the fan device to work according to the temperature sensor and controls the spraying device according to the humidity sensor.

[0008] This system monitors the environment inside and outside the cowshed through the first environment monitoring device inside the cowshed and the second environment monitoring device outside the cowshed, and controls and adjusts the devices inside the cowshed according to the monitored data, making the yak breeding more scientific and reasonable, while reducing the use of labor and being more conducive to yak breeding.

[0009] In this system, to cooperate with the use of intelligent devices, the structure of the spraying device is optimized so that the spraying device can better cooperate with this system under different conditions, achieving the best spraying effect. Specifically, the spraying device includes a moving plate with gears and the first gear, the second gear, and the third gear arranged on the fence. The moving plate is provided with nozzles. The first moving gear and the second moving gear are respectively arranged on the second gear and the third gear. The first gear can mesh with the second gear and the third gear and drive the second gear and the third gear to rotate; the first moving gear and the second moving gear can mesh with the gears of the moving plate and drive the moving plate to move up and down.

[0010] Moreover, the spraying device further includes a moving frame with gears arranged on the fence. The moving frame is provided with several nozzles. The third moving gear and the fourth moving gear are respectively arranged on the second gear and the third gear. The third moving gear and the fourth moving gear can mesh with the moving frame and drive the moving frame to move left and right.

[0011] When the data monitored by the humidity sensor is less than the first threshold during the use of this system, the cowshed is relatively dry and not suitable for the growth of yaks. Therefore, the control terminal controls the nozzles in the spraying device to work, and the nozzles spray water on the moving plate and the moving frame, thereby increasing the humidity in the cowshed. Since the data monitored by the humidity sensor is less than the first threshold, the first gear of this system meshes with the second gear and the third gear, the first gear rotates, and drives the second gear and the third gear to rotate together. During the rotation of the second gear and the third gear, the first moving gear and the second moving gear respectively mesh with the gears of the moving plate. When the first moving gear meshes with the gears of the moving plate, during the rotation of the first moving gear, it drives the moving plate to move upward. When the second moving gear meshes with the gears of the moving plate, during the rotation of the second moving gear, it drives the moving plate to move downward. During the movement of the moving plate, it drives the nozzles on it to move up and down, thereby increasing the spraying area of the cowshed and quickly increasing the humidity inside the cowshed.

[0012] At the same time, the moving frame is a rectangular frame, and gears are arranged on both the upper and lower ends of its inner side. During the rotation of the second gear and the third gear, it drives the third moving gear and the fourth moving gear on them to rotate together. The third moving gear and the fourth moving gear respectively mesh with the gears of the moving frame. When the first gear rotates and the third moving gear and the fourth moving gear mesh with the gears at the upper end of the moving frame, the moving frame moves to the right. When the third moving gear and the fourth moving gear mesh with the gears at the lower end of the moving frame, the moving frame moves to the left. By the left and right movement of the moving frame, it drives the nozzles on it to move, thereby increasing the spraying area in the left and right directions.

[0013] Preferably, the second gear is located between the first moving gear and the third moving gear, and the third gear is located between the second moving gear and the fourth moving gear.

[0014] When the data monitored by the humidity sensor is greater than the first threshold and less than the second threshold, the control terminal controls the nozzle in the spraying device to work, and the first gear is separated from the second gear and the third gear. The moving plate does not move up and down, and the moving frame does not move left and right. Spraying is directly carried out through the nozzles on it to adjust the humidity in the cowshed.

[0015] On this basis, the spraying device of this system has only one power source, the first gear. The left and right movement of the moving frame and the up and down movement of the moving plate are realized through the rotation of the first gear. This can not only save costs but also simplify the complexity of the equipment. The control terminal can directly control the rotation motor of the first gear to achieve adjustment, which is more convenient for long-term use.

[0016] Secondly, when the nozzles of this device move up and down and left and right under the action of the moving plate and the moving frame, they can wash the yaks in the fence. During the process of the nozzles moving up and down and left and right, the yaks can be washed more cleanly, and the sewage is discharged through the lower part of the cowshed, improving the use efficiency.

[0017] The left and right movement of the moving frame on the fence mainly depends on two connecting sleeves arranged on the fence. The moving frame includes two connecting rods, and the connecting rods are located in the connecting sleeves. Through the connecting rods and the connecting sleeves, the moving frame can be fixed on the fence. At the same time, when the moving frame moves left and right, the connecting rods slide in the connecting sleeves, that is, the connecting rods move left and right on the fence, and then the moving frame moves left and right on the connecting sleeves. The moving plate of this system is located in the groove on the ground in front of the fence. The lower end of the moving plate is inserted into the groove during the up and down movement. A chute can also be arranged on the moving plate, and a fixed block is arranged on the first gear. The fixed block is connected in the chute and can move up and down and rotate in the chute.

[0018] When using this system in the cowshed, in order to prevent the yaks from hitting the fence and causing the meshing between the first gear and the second gear and the third gear, a telescopic rod is arranged between the first gear and the fence. The telescopic rod can make the first gear mesh or separate from the second gear and the third gear. When the spraying device is not needed, control the telescopic rod to shorten, and the first gear is separated from the second gear and the third gear. During the long-term use process, the positional relationship between the first gear, the second gear and the third gear can be effectively protected. When needed, the telescopic rod is extended to make them mesh again, which is also more convenient for adjustment during replacement and maintenance.

[0019] Preferably, the first environmental monitoring device includes a light sensor, and the control terminal controls the rotation of the rolling curtain device according to the light sensor. For the breeding in a cowshed, appropriate lighting is required. The rolling curtain device includes a rolling curtain and a rotating motor arranged on the rolling curtain. The rolling and retracting of the rolling curtain are controlled by the rotation of the motor, so as to adjust the lighting data in the cowshed.

[0020] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0021] A digital yak breeding system of the present invention realizes comprehensive monitoring of the breeding area through existing sensing technologies and Internet of Things technologies, including temperature, humidity, lighting, video, etc. of the air inside and outside the cowshed. At the same time, it can automatically control the spraying devices in the cowshed and the free-range area, and adjust the usage mode of the spraying devices under different data conditions, so that yaks grow in a comfortable environment, thereby effectively improving the economic benefits of breeding.

[0022] Secondly, there is only one power source for the spraying device of the present system. Through the first gear, the moving plate can be moved up and down and the moving frame can be moved left and right at the same time, which not only simplifies the structure, but also saves costs and equipment maintenance, and is more convenient for long-term use.

[0023] It is beneficial to realize the industrialized, standardized and normalized management of the cowshed and the automatic control of the environment, and obtain scale benefits. It can effectively save land, resources and labor.

[0024] The present system can provide good environmental conditions for cows according to the breeding requirements of cows and the growth and development laws of cows, ensure the healthy growth of the cattle herd, and at the same time can effectively control the environment and is not easily affected by external adverse factors (high temperature, high cold, strong wind, heavy rain), so that the cattle herd grows and develops healthily in a good environment.

[0025] The present system is beneficial to disease control, beneficial to feeding operations, and automatic control is beneficial to reducing stress and reducing the generation of pathogenic factors. BRIEF DESCRIPTION OF THE DRAWINGS

[0049]

Embodiment 4

[0050] Based on the above embodiments, as Figure 2 shown, the spraying device of the present system includes a moving plate 7 with gears and a first gear 4, a second gear 5 and a third gear 6 arranged on the fence 1. A nozzle 9 is arranged on the moving plate 7. A first moving gear 51 and a second moving gear 61 are respectively arranged on the second gear 5 and the third gear 6. The first gear 4 can mesh with the second gear 5 and the third gear 6 and drive the second gear 5 and the third gear 6 to rotate; the first moving gear 51 and the second moving gear 61 can mesh with the gears of the moving plate 7 and drive the moving plate 7 to move up and down. The spraying device further includes a moving frame 8 with gears arranged on the fence 1. A plurality of nozzles 9 are arranged on the moving frame 8. A third moving gear 52 and a fourth moving gear 62 are respectively arranged on the second gear 5 and the third gear 6. The third moving gear 52 and the fourth moving gear 62 can mesh with the moving frame 8 and drive the moving frame 8 to move left and right. Two connecting sleeves 2 are arranged on the fence 1. The moving frame 8 includes two connecting rods 3, and the connecting rods 3 are located in the connecting sleeves 2.

[0051] In one or more embodiments, the moving plate 7 is located in a groove on the ground in front of the fence. In the original state, as Figure 2 shown, the lower end of the moving plate is located in the groove. Driven by the first moving gear and the second moving gear, the moving plate moves up and down, and then drives the nozzles on the moving plate to move up and down, which can not only be used to wash the yaks in the cowshed, but also adjust the humidity and temperature in the cowshed.

[0052] In one or more embodiments, a chute is arranged on the moving plate, and a fixing block is arranged on the first gear. The fixing block is connected in the chute, and the fixing block can move up and down and rotate in the chute. When the first moving gear and the second moving gear interact with the gears on the moving plate, the first moving gear and the second moving gear drive the moving plate to move up and down.

[0053] In one or more embodiments, when the data monitored by the humidity sensor is greater than the first threshold and less than the second threshold, the control terminal controls the nozzles 9 in the spraying device to work, and the nozzles spray water on the moving plate and the moving frame, and the first gear does not rotate.

[0054] When the data monitored by the humidity sensor is less than the first threshold, the control terminal controls the nozzle 9 in the spraying device to work. The nozzle sprays water on the moving plate and the moving frame. At the same time, the first gear rotates. The first gear 4 meshes with the second gear 5 and the third gear 6. The rotation of the first gear drives the second gear 5 and the third gear to rotate together. During the rotation of the second gear 5 and the third gear, the first moving gear 51 and the second moving gear 61 respectively mesh with the gears of the moving plate 7. When the first moving gear meshes with the gears of the moving plate 7, as Figure 3 shown, during the rotation of the first moving gear, it drives the moving plate to move upward. When the second moving gear 61 meshes with the gears of the moving plate 7, as Figure 4 shown, during the rotation of the second moving gear, it drives the moving plate to move downward.

[0055] At the same time, as shown in the figure, the moving frame is a rectangular frame, and gears are arranged on both the upper and lower ends of its inner side. A number of nozzles are arranged on the side of the moving frame close to the cowshed. The second gear 5 of this device is as Figure 5 shown, the third gear 6 is as Figure 6 shown. The first moving gear 51 and the third moving gear 52 on the second gear 5 have the same shape and structure. The second gear 5 is located between the first moving gear 51 and the third moving gear 52. The first moving gear 61 and the third moving gear 62 on the third gear have the same shape and structure. The third gear 5 is located between the second moving gear 61 and the fourth moving gear 62. The side view of the second gear is as Figure 7 shown.

[0056] During the rotation of the second gear 5 and the third gear, it drives the third moving gear 52 and the fourth moving gear 62 on them to rotate together. The third moving gear 52 and the fourth moving gear 62 respectively mesh with the gears of the moving frame. When the first gear rotates and the third moving gear and the fourth moving gear 62 mesh with the gears at the upper end of the moving frame, as Figure 8 shown, the moving frame moves to the right. When the third moving gear and the fourth moving gear 62 mesh with the gears at the lower end of the moving frame, as Figure 2 shown, the moving frame moves to the left. The movement of the moving frame left and right drives the nozzles on it to move, thereby increasing the spraying area in the left and right directions. In this embodiment, the first threshold and the second threshold are adjusted according to the actual usage situation.

[0057]

Embodiment 5

[0058] On the basis of the above embodiment, as Figure 9As shown, a telescopic rod 10 is provided between the first gear 4 and the fence 1. The telescopic rod 10 can be extended to make the first gear 4 engage or disengage with the second gear 5 and the third gear 6. The structure of the first gear 4 is as shown in FIG. Figure 10 shown.

[0059] The control terminal controls the extension and retraction of the telescopic rod 10 according to the monitoring data, so that the nozzle 9 in the spraying device works and the first gear 4 is separated from the second gear 5 and the third gear 6.

[0060] When the data monitored by the humidity sensor is less than the first threshold, the control terminal controls the nozzle 9 in the spray device to work and the telescopic rod 10 to extend, the first gear 4 is meshed with the second gear 5 and the third gear 6, the first gear rotates, and the nozzle sprays water. When the data monitored by the humidity sensor is greater than the first threshold and less than the second threshold, the control terminal controls the nozzle 9 in the spray device to work and the telescopic rod 10 to shorten, the first gear 4 is separated from the second gear 5 and the third gear 6, the first gear does not rotate, and the nozzle sprays water.

[0061] [Example 6]

[0062] The Internet of Things technology is used in the cowshed to monitor the temperature, humidity, light, carbon dioxide concentration, ammonia concentration, hydrogen sulfide concentration and other data in the cowshed. The collected data is transmitted to the control terminal through Ethernet and other communication methods. The control terminal processes the data and can display the temperature, humidity, light, carbon dioxide concentration, ammonia concentration, and hydrogen sulfide concentration in the cowshed in real time. The control terminal performs intelligent analysis on the collected data and links the cowshed fan, lighting, sunshade, and spraying to achieve automatic control. The fixed-point ball machine can transmit the collected video signal to the control terminal through the router to monitor the situation in the cowshed in real time or at a fixed time. Managers can log in to the control terminal at any time through the PC or mobile phone APP to view the data.

[0063] [Example 7]

[0064] All farmed yaks in the cowshed are equipped with smart ear tags, which can be identified and read through ear tag reading terminals, making it easier to manage cattle and trace their entire history. In this embodiment, ultra-high frequency ear tags and ultra-high frequency RFID readers are used, with a reading and writing distance of 2 meters. If a gain antenna is installed, it can reach a longer distance. The handheld device uploads the read ear tag information to the control terminal, which searches and returns relevant data to the handheld device through comparison. At the same time, the label design of the traditional ear tag is adopted, so that managers can judge yaks with their naked eyes or with handheld devices, which is convenient for managers to manage beef cattle.

[0065] This system also includes a weighing sensor. When a cow passes through the intelligent group weighing device, the system will automatically identify the electronic ear tag and collect the weight data, realizing the automatic grouping of cows and making the weighing more efficient and refined.

[0066]

Embodiment 8

[0067] A constant-temperature drinking trough is arranged in the cowshed of this system. The constant-temperature drinking trough includes a waterproof temperature sensor for monitoring the water temperature. Since yaks have strict requirements for the water temperature of drinking water and the water is heated by burning cow dung, the fluctuation of the water temperature may exceed the drinking water requirements. Therefore, it is necessary to monitor the water temperature of the drinking water. The bottom of the trough is heated by an electric heating tube, and the power supply of the electric heating tube is controlled by the perception of the temperature sensor. The temperature range can be customized by the user to set the temperature threshold. At the same time, a float is placed in the trough. The float is used to control the water supply system. When the float is lower than the lowest critical point, the water supply system can supply water to the trough. When the float is higher than the highest critical point, the water supply system will stop supplying water. The drainage system can be controlled regularly to prevent some water from remaining in the trough all the time and deteriorating or being polluted.

[0068] The flow-limiting device for controlling the entry and exit of yaks from the constant-temperature drinking trough is an existing device. It can be a railing and a lifting device installed on both sides of the trough. The railing is controlled by the lifting device to adjust the height, thereby controlling the entry and exit of yaks from the constant-temperature drinking trough. When the lifting device drives the railing to rise, yaks cannot enter the constant-temperature drinking trough. When the lifting device drives the railing to lower, yaks can enter the constant-temperature drinking trough. The lifting device can be a telescopic rod or other telescopic structures.

[0069] When the RFID reader collects the identification information of the yak, the control terminal controls the lifting device to drive the railing to rise to prevent another yak from entering the drinking water, controls the number of beef cattle entering the trough to drink water, ensures that there is only one cow at the trough, collects the identification information of the yak through the RFID reader, and generates a record of coming to drink water. By regularly polling and scanning the drinking water records in the database, if it is found that a yak has exceeded the drinking time threshold and has not come to drink water, an alarm message will be generated and sent to the administrator through the platform, email or text message, so that the administrator can go to check whether the yak is ill or has other special reasons. Digital breeding is realized through the above embodiments.

It should be understood that the above description is only for the specific embodiments of the present invention and is not intended to limit the protection scope of the present invention.
