Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of breeding, and particularly relates to a pig driving stick and a pig driving device. BACKGROUND

[0002] In a modernized breeding farm, according to the types of pigs, the farrowing pens of breeding pigs, boars, replacement gilts and sows are arranged in different areas of the pig farm. In the life cycle of pigs, they need to be moved among different feeding areas in the breeding farm according to their month age or different physiological states. For example, replacement gilts are fed in the first area, and when they are close to the delivery period (for example, one week before the expected delivery date), they are transferred to the replacement gilt farrowing pen for delivery preparation. At the same time, in the process of feeding pigs, in order to know the growth curve in time, the body weight and body length of pigs are measured regularly, and the pigs also need to be transferred from the feeding area to the measurement area.

[0003] Among them, when the pigs are transferred from one area to another area, the transfer channel between the areas is usually used to realize the transfer in the conventional state. In the transfer process, in order to guide the pigs to move from one direction to another direction, the feeders usually use the pig driving stick to drive.

[0004] The pig driving stick in the prior art is actually a stick, which is directly hit on the body of the pig by the feeders to drive the pig to move in a single desired direction. However, this method has the following problems: when the driving force is insufficient, the driving effect on the pig is limited, and when the driving force is large, the skin of the pig is easily damaged and bruised.

[0005] There is also a pig driving stick in the prior art, which integrates an electrode, and the pig is stimulated by electric shock. This method does not cause the pig's skin to be bruised, but also affects the health of the pig.

[0006] Existing technology also includes a sound-generating pig-driving device, but these devices either use electrical simulation or simply impact-based sound generation. Electrical simulation struggles to create realistic slapping sounds; the resulting sounds are static and eventually become background noise for the pigs, making it difficult to drive them away solely through sound. Impact-based sound generation requires heavy, metallic objects to produce a loud sound. This means the herding stick must be very heavy, with a metal outer shell, increasing the burden on the handler—an ineffective burden. Furthermore, the handler must swing the stick quickly and forcefully (defying the original purpose of a sound-generating herding stick). When the herding stick moves slowly, the impact beads have low acceleration and receive little impact upon contact with the metal wall, resulting in a low loudness. Summary of the Invention

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0048] Embodiment 1:

[0049] With reference to Figures 1-9A preferred embodiment of the present invention provides a pig-driving stick 100, used to drive a target object along a preset path to reach a corresponding destination. The target object is a pig, and its species is not limited, including breeding pigs, boars, gilts, sows, etc., or may include spotted pigs, domestic pigs, etc., without specific limitation, depending on the actual situation.

[0050] The preset path can be determined based on the shape of the transfer channel. For example, if the transfer channel is shaped like a square or a zigzag line, the pigs can be driven to move along the shaped transfer channel.

[0051] Specifically, the pig-driving stick 100 includes a rod body 1 and a sound-generating mechanism 2 disposed within the rod body 1. The rod body 1 is cylindrical, making it easy to hold and comfortable. A cavity 13 is provided along the axial length of the rod body 1, and the sound-generating mechanism 2 is disposed within this cavity 13. The sound-generating mechanism 2 can emit a sound within the cavity 13 to drive the pig accordingly.

[0052] The lever 1 includes a handle 11 and a driving part 12 connected to the handle 11. A receiving cavity 13 is disposed inside the driving part 12, thereby enabling the driving part 12 to emit a sound to drive the pigs. The handle 11 is for the farmer to hold and operate the lever 1.

[0053] To provide a better grip on the handle 11, the rod body 1 also includes an anti-slip component disposed on the outer side of the handle 11. The anti-slip component may be a silicone pad disposed on the outer circumferential surface of the handle 11, or a protrusion formed by extending outward from the surface of the handle 11, etc., without being specifically limited here, depending on the actual situation.

[0054] In this embodiment, the handshake part 11 and the driving part 12 can be integrally formed, or they can be set separately and then fixedly connected by fasteners, snap-fit ​​or other means. No specific limitation is made here, and it depends on the actual situation.

[0055] The sound generating mechanism 2 can work together with the rod 1 and / or the accommodating cavity 13 under the action of external force to produce a sound. The magnitude of the sound must be such that the target object can produce a corresponding reaction, including but not limited to: moving in a preset direction upon hearing the sound; or moving in the direction of the sound upon hearing it. Therefore, the magnitude of the sound can be set according to the target object's reaction, and is not specifically limited here.

[0056] In one embodiment, the external force that enables the sound-generating mechanism 2 to produce sound is a human-induced force. That is, the zookeeper taps the rod 1, causing the sound-generating mechanism 2 inside the rod 1 to vibrate and produce sound.

[0057] However, the artificial force here needs the breeder to continuously exert force and make sound, which will cause burden to the breeder himself, and the breeder needs to exert enough force to make the pig driving stick 100 produce sound that can affect the movement of the pig.

[0058] Therefore, in another embodiment, the rod body 1 of the pig driving stick 100 is also provided with an airflow channel 15, which is arranged on the holding hand part 11 and / or the driving part 12. The first air inlet 151 of the airflow channel 15 is in communication with the airflow generating mechanism 4, and the first air outlet 152 of the airflow channel 15 is in communication with the accommodating cavity 13. The airflow generated by the airflow generating mechanism 4 flows to the accommodating cavity 13 through the airflow channel 15, so that the sound generating mechanism 2 generates sound.

[0059] Among them, the airflow channel 15 is parallel or tends to be parallel to the accommodating cavity 13. The meaning of "tends to" is that the airflow channel 15 and the accommodating cavity 13 are parallel to the naked eye. By arranging the airflow channel 15 and the accommodating cavity 13 to be parallel or tend to be parallel, the airflow in the airflow channel 15 can flow directly into the accommodating cavity 13, so that the flow speed loss of the airflow is minimized to ensure the sound intensity of the sound generated by the sound generating mechanism 2.

[0060] The above-mentioned airflow generating mechanism 4 can be an external air pump. At this time, the air pump is in communication with the first air inlet 151 of the airflow channel 15 through a connecting pipeline, so that the gas after the air pump operates is transported into the airflow channel 15 through the connecting pipeline. Among them, the operating power of the air pump can be adjusted, so as to correspondingly control the flow rate of the airflow entering the airflow channel 15. At this time, the working time of the airflow generating mechanism 4 will not be limited, and the air pump can always be connected to the mains or the corresponding power supply for work.

[0061] Alternatively, in another embodiment, the above-mentioned airflow generating mechanism 4 can be directly connected and installed with the rod body 1, which is convenient for the breeder to hold the pig driving stick 100 to move, and will not limit the movement range of the breeder.

[0062] The airflow generating mechanism 4 is rotationally connected with the rod body 1, and the rod body 1 is provided with a piercing piece 17. When the airflow generating mechanism 4 is connected with the rod body 1, the piercing piece 17 pierces the third air outlet 41 of the airflow generating mechanism 4. In this embodiment, the airflow generating mechanism 4 is rotationally connected with the holding hand part 11. That is, the airflow generating mechanism 4 and the driving part 12 are respectively arranged at both ends of the holding hand part 11, so that the airflow of the airflow generating mechanism 4 is directly transported to the accommodating cavity 13 through the airflow channel 15.

[0063] The rotation connection between the air flow generating mechanism 4 and the rod body 1 is a threaded connection. The piercing member 17 is a pointed object, and the pointed end is arranged towards the third air outlet 41 of the air flow generating mechanism 4. When the air flow generating mechanism 4 is rotated to be tightly connected with the rod body 1, the pointed end will pierce the third air outlet 41 of the air flow generating mechanism 4.

[0064] The rod body 1 also has a communication channel 16 which communicates the air flow channel 15 and the third air outlet 41, and the piercing member 17 is arranged in the communication channel 16. In addition, the rod body 1 includes a support member 111 arranged in the communication channel 16, and the piercing member 17 is connected with the support member 111. The support member 111 can be a cross-shaped or a straight-shaped. In the embodiment, the communication channel 16 is arranged in the hand holding part 11, and the communication channel 16 is parallel or tends to be parallel with the accommodating cavity 13, so as to avoid reducing the flow speed of the air flow.

[0065] In addition, in the embodiment, the air flow generating mechanism 4 is a handheld air pump which has a battery pack. The battery pack can power the air pump, and the battery pack can be removed or directly charged when the air pump has low power or is out of power.

[0066] The pig driving stick 100 also includes a valve mechanism 3 which is movably arranged at the first air inlet 151 of the air flow channel 15, so as to open or block the first air inlet 151, so as to communicate or block between the air flow generating mechanism 4 and the air flow channel 15. By arranging the valve mechanism 3, the first air inlet 151 of the air flow channel 15 can be opened or closed, so that the sound generating mechanism 2 can be controlled, so that the sound generating mechanism 2 can vibrate to generate sound or be stationary to avoid generating sound, so that the mode can be switched according to the corresponding application scene and application environment.

[0067] Specifically, the valve mechanism 3 includes a piston 31 which is suitable for blocking or opening the first air inlet 151, a lever 32 which is connected with the piston 31 and drives the piston 31 to move relative to the first air inlet 151 under the action of an external force, and the lever 32 is applied to move relative to the first air inlet 151, so as to open or block the first air inlet 151.

[0068] In one embodiment, the lever 32 can move relative to the first air inlet 151, and at this time, the moving direction of the lever 32 is perpendicular or parallel to the flow direction of the air flow.

[0069] In another embodiment, the lever 32 can rotate relative to the first air inlet 151. At this time, the rod body 1 further has a sliding cavity 14 in communication with the first air inlet 151, and the piston 31 is slidingly arranged in the sliding cavity 14, and the lever 32 is rotatably arranged outside the sliding cavity 14. The lever 32 is driven to rotate by applying an external force, so that the lever 32 drives the piston 31 to slide in the sliding cavity 14, thereby plugging or opening the first air inlet 151. The sliding cavity 14 and the airflow passage 15 form an included angle. In this embodiment, the included angle between the sliding cavity 14 and the airflow passage 15 is 90°, and in other embodiments, the included angle between the sliding cavity 14 and the airflow passage 15 can also be 75°, 30°, 45°, etc., which is not limited here and is determined according to the actual situation.

[0070] The lever 32 is provided with a sliding groove 321 having a first end 322 and a second end 323 arranged opposite to each other. The connecting part 311 of the piston 31 is slidingly connected with the sliding groove 321. The lever 32 is driven to move by applying an external force, so that the connecting part 311 slides between the first end 322 and the second end 323. When the connecting part 311 is located at the first end 322 or the connecting part 311 is located at the first end 322 and the end of the lever 32 close to the piston 31 is located at the lowest position, the piston 31 plugs the first air inlet 151. The lowest position is the stop position of the lever 32 moving in the direction close to the rod body 1 under the action of the external force. When the lever 32 is rotated under the action of the external force to make the connecting part 311 slide from the first end 322 to the second end 323, the piston 31 opens the first air inlet 151. The stop position is that the lever 32 cannot continue to rotate in the current rotation direction when it is rotated to this position.

[0071] The valve mechanism 3 further comprises a first elastic member 33 sleeved on the piston 31. When the piston 31 plugs the first air inlet 151, the first elastic member 33 is in an initial state. When an external force is applied to the lever 32 to drive the piston 31 to move to open the first air inlet 151, the first elastic member 33 is compressed. When the external force is removed, the first elastic member 33 restores under the action of its elastic force to make the piston 31 move to the initial position. In this embodiment, the first elastic member 33 is a spring.

[0072] As described above, the rod body 1 further has a communication passage 16 arranged parallel or tending to be parallel to the airflow passage 15. The second air inlet 161 of the communication passage 16 is in communication with the airflow generating mechanism 4, and the second air outlet 162 is in communication with the sliding cavity 14. When the piston 31 plugs the first air inlet 151, the second air outlet 162 is also plugged. When the connecting part 311 moves from the first end 322 to the second end 323, the piston 31 opens the second air outlet 162.

[0073] The sound generating mechanism 2 is provided with a sound generating part 21 arranged in the accommodating cavity 13, a sliding part 22 arranged in the sliding cavity 14, and a rotating part 23 connecting the sound generating part 21 and the sliding part 22, and the sliding part 22 is arranged opposite to the piston 31. The second air outlet 162 is arranged opposite to the first air inlet 151, and the diameter of the second air outlet 162 is larger than that of the first air inlet 151, so that the air flow from the second air outlet 162 is gathered in the sliding cavity 14, and the air flow speed flowing into the air flow channel 15 is increased. Meanwhile, the sliding of the sliding part 22 is provided with a force, so that the sliding part 22 moves away from the piston 31 under the action of the gathered air flow, and then drives the rotating part 23 to rotate. The sliding part 22 is substantially the same as the piston 31, and also has a blocking effect.

[0074] That is, the piston 31 moves to open the second air outlet 162, and the sliding part 22 moves under the action of the air flow from the second air outlet 162 into the sliding cavity 14, so that the rotating part 23 rotates and drives the sound generating part 21 to move to generate sound.

[0075] The sound generating part 21 includes a rope 211 connected with the rotating part 23 and a vibrating sound plate 212 connected with the rope 211, the sliding part 22 slides to drive the rotating part 23 to rotate, and then drives the rope 211 to be tight so that the vibrating sound plate 212 vibrates to generate sound. That is, when the rotating part 23 does not rotate, the rope 211 is in a relaxed state. When the rotating part 23 rotates under the action of the sliding part 22, the rope 211 is pulled to be tight.

[0076] The sound generating mechanism 2 further includes a second elastic part 24 arranged on the sliding part 22. The second elastic part 24 has the same effect as the first elastic part 33, and will not be described herein. Similarly, the second elastic part 24 is a spring.

[0077] The application further provides a pig driving device, which comprises a support frame and a pig driving stick 100, wherein the support frame has a plurality of clamping parts, and the pig driving stick 100 is clamped with the clamping parts to be placed on the support frame. When the pig driving stick 100 needs to be taken out, an external force is applied to the pig driving stick 100 and / or the support frame, so that the pig driving stick 100 is separated from the support frame.

[0078] The support frame is further provided with a gas pumping mechanism, which is used for pumping gas for the air flow generating mechanism 4 of the pig driving stick 100 installed on the support frame. When the pig driving stick 100 is placed on the support frame, the gas pumping mechanism can be communicated with the third air inlet of the air flow generating mechanism 4 to pump gas. The gas pumping mechanism is a conventional structure, such as an air pump, which will not be limited herein and is determined according to the actual situation.

[0079] In summary: by being provided with the rod body 1, the sound generating mechanism 2 and the valve mechanism 3, the rod body 1 is provided with the accommodating cavity 13 and the airflow channel 15 communicated with the accommodating cavity 13, and the airflow channel 15 is communicated with the airflow generating mechanism 4, so that the airflow generated by the airflow generating mechanism 4 can flow to the accommodating cavity 13 through the airflow channel 15, and the sound generating mechanism 2 arranged in the accommodating cavity 13 can emit sound, thereby realizing the pig driving effect; and the valve mechanism 3 is movably arranged at the first air inlet 151 of the airflow channel 15, so as to open or block the first air inlet 151, thereby connecting or blocking the airflow generating mechanism 4 and the airflow channel 15, and further controlling whether the sound generating mechanism 2 generates sound, which is convenient and fast, and does not need to exert external force, directly drives the movement of the sound generating mechanism 2 by the impact of the airflow; and the pig driving rod 100 does not need to act on the pig, and does not produce ecchymosis on the pig to affect the pig itself.
