[0037] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other.

[0038] The present application provides a cattle hoof spraying device. The following describes the cattle hoof spraying device provided by the present application in detail through multiple examples in conjunction with the accompanying drawings. It should be noted that the cattle hoof spraying device provided by the present application can also be used to prevent and treat hoof diseases of other animals, such as sheep hoof disease. The following embodiments of the present application are only used to illustrate cattle hoof disease, and do not mean that the cattle hoof spraying device of the present application can only be used to prevent and treat cattle hoof diseases.

[0039] Figure 1 This is a schematic diagram of the structure of the cattle hoof spraying device provided in the embodiment of the present application, as shown in FIG. Figure 1 As shown, the cattle hoof spraying device includes: a spraying channel 1, a plurality of pedal assemblies 2 and a spraying assembly (not shown in the figure).

[0040] The multiple pedal assemblies are sequentially arranged in the bottom area of ​​the spraying channel along the predetermined channel extension direction. Spraying ports 3 are provided on the tread surfaces of the multiple pedal assemblies. The multiple pedal assemblies are used to connect to a control device. In this embodiment, for example, 13 pedal assemblies may be provided on the spraying channel, each with two spraying ports. That is, there are a total of 13 pedal assemblies and 26 spraying ports on the spraying channel. The 26 spraying ports are located at the natural stepping positions of the cow's hooves when the cow passes through the spraying channel.

[0041] Specifically, each pedal assembly may include, for example, a pedal, a pressure spring disposed on the bottom surface of the pedal, and a sensor disposed on the side surface of the pedal.

[0042] Among them, the pedal can be made of stainless steel or other trample-resistant materials. The pedal is used to withstand the trampling of cow hooves. A spray port is provided on the top surface of the pedal. The pressure spring is used to bounce back after the pedal is pressed down and lifted by the cow, so that the pedal can be repeatedly stepped on and pressed down; the sensor is used to sense the depression action of the pedal and generate a depression signal, or to sense the lifting action of the pedal and generate a lifting signal. The sensor is also used to connect to the control device. The sensor can send the depression signal or the lifting signal to the control device, so that the control device controls the corresponding target nozzle below the spray port to perform the spraying action based on the depression signal or the lifting signal.

[0043] like Figure 2 As shown, the spray assembly is arranged at the side position of the spray channel. The spray assembly is equipped with a plurality of liquid medicine dispensers 31, and each liquid medicine dispenser is connected to a corresponding dedicated nozzle. The spray assembly is connected to a preset medicine storage device through a pipeline system. The latter serves as a core container for storing medicine and can stably supply medicine. The layout of the multiple nozzles is precisely matched with the position of the spray port on the pedal assembly, that is, a dedicated nozzle is vertically arranged directly below each spray port, and each nozzle is independently connected to a dedicated liquid medicine dispenser. When the spray assembly is working, the medicine in the preset medicine storage device is transported to the liquid medicine dispenser through the pipeline, and after precise measurement, it is ejected at high speed by the nozzle directly to the corresponding spray port, finally completing the precise spraying operation and ensuring that the medicine evenly covers the target area. Combined with Figure 1 When there are 26 spray ports, there are also 26 nozzles, and the nozzles correspond to the spray ports one by one.

[0044] The spray assembly is also connected to a control device, so that the control device controls the target nozzle corresponding to the spray port of the target pedal assembly to perform a spraying action based on the depression signal and the lift signal sequentially generated by the target pedal assembly. Specifically, when a cow steps on a target pedal assembly among the multiple pedal assemblies, the target pedal assembly is depressed, and the sensor senses the depression of the pedal, generates a depression signal, and transmits it to the control device. The control device then controls the target nozzle corresponding to the spray port on the target pedal assembly to perform a spraying action. Because a pressure-bearing spring is provided on the bottom surface of the target pedal assembly, the target pedal assembly is also rebounded by the pressure-bearing spring after being depressed. Therefore, the sensor also senses the lift of the pedal, generates a lift signal, and transmits it to the control device. The control device then controls the target nozzle corresponding to the spray port on the target pedal assembly to perform a spraying action again. In other words, when the cow steps on the target pedal assembly once, the target nozzle corresponding to the spray port performs a spraying action twice.

[0045] In summary, this embodiment provides a cow hoof spraying device, which automatically sprays the cow's hooves when the cow passes through the spraying channel, is highly efficient and saves manpower and material resources. Moreover, when the cow steps on the target pedal assembly, based on the downward pressure signal and the upward pressure signal of the target pedal assembly, the corresponding target nozzle can perform two spraying actions, ensuring that the cow's hoof can be sprayed with medicine, thereby improving the coverage rate of the spray on the cow's hoof surface.

[0046] It should also be noted that, in this embodiment, the overall width of the pedal assembly is determined based on the actual width of the cow's hoof. It is sufficient to ensure that when the cow enters the spraying channel, the hoof can step near the sensor position. The number of pedal assemblies (that is, the length of the spraying channel) is set based on the body length of the entire cow to ensure that each hoof is sprayed an average of 4 times after the cow has completely passed through the spraying channel.

[0047] Continue to refer to Figure 2 The spraying assembly also includes: a liquid medicine delivery pipeline 32 and multiple separate control valves 33. Both ends of the liquid medicine delivery pipeline are connected to a preset medicine storage device. The liquid medicine delivery pipeline is a multi-porous pipeline. The multiple separate control valves are respectively arranged at the positions of multiple medicine outlet holes on the liquid medicine delivery pipeline. The multiple separate control valves are also connected to multiple nozzles.

[0048] The multiple individual control valves are used to connect the control device so that the control device controls the target nozzle to perform a spraying action through the target individual control valve connected to the target nozzle based on a depression signal or a lift signal of the target pedal assembly.

[0049] The spray assembly may also include two main control valves 34, each connecting the two ends of the liquid medicine delivery pipeline to a predetermined medicine storage device. Both main control valves are connected to a control device, which can control the opening and closing of the two main control valves, thereby controlling the connection or disconnection between the entire liquid medicine delivery pipeline and the predetermined medicine storage device. The multiple individual control valves and the two main control valves can be, for example, solenoid valves. Both the multiple individual control valves 33 and the two main control valves 34 are one-way valves to prevent the liquid medicine from flowing back.

[0050] In one embodiment, the spraying assembly may further include two filter assemblies (not shown in the figure), which are respectively arranged at both ends of the medicine delivery pipeline to filter the medicine liquid in the pipeline to prevent the pipeline from being blocked.

[0051] In one embodiment, the input end of the medicine delivery pipeline is also connected to a preset medicine storage device through a variable frequency pump. The variable frequency pump is used to ensure that there is continuous pressure in the medicine delivery pipeline, so that the medicine in the preset medicine storage device can be delivered to the medicine delivery pipeline.

[0052] In one embodiment, the pedal assembly may further include a rubber pad disposed on the top surface of the pedal. The rubber can act as a buffer when the cow's hoof steps on the pedal and protect the entire pedal assembly.

[0053] The pedal assembly can also include a sensor fixing bracket, a sensor fixing seat and a nozzle fixing seat. The sensor is fixed on the sensor fixing seat. The sensor fixing bracket fixes the sensor fixing bracket to the side of the pedal. The sensor fixing bracket also fixes the nozzle fixing seat at the corresponding position of the nozzle mouth, which is used to fix the position of the nozzle at the corresponding position of the nozzle mouth.

[0054] Based on the cattle hoof spraying device provided in the above embodiment, Figure 3 As shown, the present application also provides a cattle hoof spraying system, which includes the cattle hoof spraying device provided in any of the above embodiments, a preset drug storage device, and a control device. The spraying assembly in the cattle hoof spraying device is connected to the preset drug storage device, and the spraying assembly and pedal assembly in the cattle hoof spraying device are also connected to the control device. The cattle hoof spraying system can automatically spray the liquid medicine in the preset drug storage device onto the surface of the cattle hoof, thereby preventing and treating cattle hoof diseases.

[0055] like Figure 4 As shown, the present application also provides a method for controlling the spraying of cattle hooves, which is applied to the control device in the above-mentioned cattle hooves spraying system, and the method includes:

[0056] S100: Obtain a depression signal and a lift signal generated in sequence after a target pedal assembly in a cow hoof spraying device is stepped on by a cow hoof.

[0057] When a cow passes through the spraying channel, it will step on a target pedal assembly among the multiple pedal assemblies. At this time, the control device can obtain the depression signal and the lift signal sent by the sensor corresponding to the target pedal assembly.

[0058] S200, according to the pressing signal and the lifting signal, sequentially controlling the target nozzles corresponding to the spraying ports of the target pedal assembly in the cattle hoof spraying device to perform spraying actions.

[0059] Then, according to the pressing signal and the lifting signal, the control device can sequentially control the target nozzle corresponding to the spraying port of the target pedal assembly in the cattle hoof spraying device to perform the spraying action.

[0060] The method of this embodiment can automatically spray medicine on the cow's hooves when the cow passes through the spraying channel, which is highly efficient and saves manpower and material resources. Moreover, when the cow steps on the target pedal assembly, based on the depression signal and the lift signal of the target pedal assembly, the corresponding target nozzle can perform two spraying actions, ensuring that the cow's hooves can be sprayed with medicine, thereby improving the coverage rate of the spray on the cow's hoof surface.

[0061] Optionally, a lifting device is provided inside the legs of the spray channel, which can conveniently adjust the height of the cattle hoof spraying system. This design enables the cattle hoof spraying system to complete corresponding tasks more efficiently in transportation, maintenance and cleaning. The spraying system also has a heating function. Taking the medicine delivery pipeline as an example, a heating jacket is provided on it. When the temperature is low, the heating jacket can play a role to ensure that the medicine will not freeze due to the low temperature, thereby ensuring the normal operation of the spraying system.

[0062] Figure 5 The schematic diagram of the structure of the preset drug storage device provided in this application is as follows: Figure 5 As shown, the input end of the medicine delivery pipeline is also connected to multiple preset medicine storage devices (two in the figure, 41 and 42 respectively) through the frequency conversion pump 4. The frequency conversion pump 4 is connected to the two preset medicine storage devices respectively. Different medicines can be stored in the two preset medicine storage devices. Through the operation of the frequency conversion pump, the medicine in the medicine storage device can be accurately delivered to the medicine delivery pipeline to meet subsequent use needs.

[0063] Figure 6 This is a schematic diagram of the electrical execution unit built into the spray channel. Figure 7 The diagram below shows a schematic diagram of the control device. The electrical actuator unit 5 is located on one side of the spray channel (the spray assembly is located on the other side of the channel) and is responsible for controlling the liquid dispenser to spray. The control device 6 controls the operation of the electrical actuator unit 5 according to a pre-programmed program.

[0064] The control device plays a key role in connecting and regulating the entire system. It is not only connected to the sensor, but also to multiple separate control valves. During the actual operation of the cattle hoof spraying device, when the sensor detects the depression or lifting of the pedal and sends the corresponding depression signal and lift signal to the control device, the control device will accurately control the target liquid dispenser corresponding to the spray port to perform the spraying action based on the received signal, thereby realizing automated spraying operation. In summary, this application has the following advantages:

[0065] 1. The mechanism of triggering the spraying with a physical pressure plate ensures the accuracy of the spraying. The liquid medicine will be sprayed directly onto the cow's hooves. Compared with using a photoelectric switch to identify the position of the cow and spray the medicine, this application is triggered by a physical pressure plate, which reduces the possibility of false triggering and is suitable for high-flow pasture environments.

[0066] 2. Each pressure plate assembly will trigger the spraying every time the cow's hoof is pressed down and lifted. When the cow passes through a pressure plate assembly, the spraying will be triggered twice, further ensuring that the medicine liquid is sprayed on the hoof surface and achieving precise spraying, greatly improving the utilization rate of the medicine liquid.

[0067] 3. Each nozzle is connected to a separate control valve, and each nozzle can be controlled individually, which ensures that each spraying action is precisely synchronized with the movement of the cow's hoof, reducing the waste of liquid medicine.

[0068] 4. The spray port is facing the stress-bearing surface of the cow's hoof, and the liquid medicine can quickly cover the surface of the cow's hoof, ensuring that each hoof can be sprayed evenly.

[0069] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
