Description

Technical Field

[0001] The invention relates to the technical field of breeding, in particular to a pig-driving stick and a pig-driving device. Background Art

[0002] In modern breeding farms, the farrowing rooms for breeding pigs, boars, gilts, and sows are set up in different areas of the pig farm according to the type of pigs. In addition, during the life cycle of pigs, they need to move between different feeding areas in the farm according to their age or different physiological conditions. For example, gilts are raised in the first area, and when they are about to give birth (for example, one week before the due date), they will be transferred to the gilt farrowing room to wait for delivery. At the same time, in the process of pig breeding, in order to know their growth curve in time, their weight and body length will be measured regularly. When measuring their weight and body length, the pigs also need to be transferred from the feeding area to the measurement area.

[0003] When transferring pigs from one area to another, the transfer passages between areas are usually used. During the transfer process, the breeder usually drives the pigs with a pig driving stick to guide the pigs from one direction to another.

[0004] The existing pig-driving stick is actually a stick itself, which is driven by the breeder to hit the pig directly with the stick to drive the pig to move in a single desired direction. However, the problem with this method is that when the force is insufficient, the effect of driving the pig is limited, and when the force is too strong, it is easy to cause damage to the pig's skin and bruises.

[0005] There is also a pig-driving stick in the prior art, in which electrodes are integrated, which stimulates the pigs by electric shock. Although this method will not cause bruises on the pigs' skin, it also affects the health of the pigs themselves.

[0006] The prior art also provides a pig-driving device that can make sounds, but the sound-generating device in the prior art either uses electrical simulation sound generation or only uses impact sound generation. It is difficult to create a real slapping sound with electrical simulation sound generation, and the sound that appears is solidified every time. In the long run, it will be regarded as background sound by pigs, and it is difficult to drive pigs only by sound. If a very loud sound is to be made by impact sound generation, the objects that collide with each other must be set to metal, and the impact sound emitted by the metal with a large mass is strong. That is, the mass of the pig-driving stick is very large, and the shell material of the pig-driving stick must be metal, which will increase the weight of the breeder when driving the pigs, and the weight is an invalid weight. At the same time, the breeder must swing the pig-driving stick quickly and vigorously (this violates the original intention of setting the sound-generating pig-driving stick). When the speed of the moving pig-driving stick is slow, the acceleration of the impact bead is small, and when it contacts the metal wall of the pig-driving stick, the impulse received is small, and its loudness is still very small. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1:

[0049] Reference Figure 1-Figure 9A pig-driving stick 100 in a preferred embodiment of the present invention is used to drive a target object to move along a preset path to reach a corresponding destination. The target object is a pig, and its type is not limited, and may include a breeding pig, a breeding boar, a gilt, a sow, etc., or a spotted pig, a domestic pig, etc., which is not specifically limited here and depends on the actual situation.

[0050] The preset path can be determined according to the shape of the transfer passage. For example, the transfer passage is in the shape of a U-shaped or a zigzag shape, and the pigs can be driven to move along the transfer passage in the shape of a U-shaped or a zigzag shape.

[0051] Specifically, the pig-driving rod 100 includes a rod body 1 and a sound-generating mechanism 2 disposed in the rod body 1. The rod body 1 is a cylinder, which is convenient to hold and does not cause discomfort. The rod body 1 is provided with a receiving cavity 13 along its axial length direction, and the sound-generating mechanism 2 is disposed in the receiving cavity 13. The sound-generating mechanism 2 can emit a sound in the receiving cavity 13 and then drive the pigs accordingly.

[0052] The rod body 1 includes a gripping portion 11 and a driving portion 12 connected to the gripping portion 11. The accommodating cavity 13 is disposed in the driving portion 12, so that the driving portion 12 as a whole can make a sound to drive the pigs. The gripping portion 11 is for the breeder to hold so as to operate the rod body 1 accordingly.

[0053] In order to better grip the grip portion 11, the rod body 1 further includes an anti-slip member disposed on the outer side of the grip portion 11. The anti-slip member may be a silicone pad disposed on the outer circumference of the grip portion 11, or a convex point protruding outward from the surface of the grip portion 11, etc., which is not specifically limited here and is determined according to actual conditions.

[0054] In this embodiment, the handshake portion 11 and the driving portion 12 can be integrally formed, or can be separately provided and fixedly connected by fastener connection, snap connection, etc., which is not specifically limited here and depends on actual conditions.

[0055] The sound generating mechanism 2 can work together with the rod body 1 and / or the accommodating chamber 13 under the action of external force to generate a sound. The magnitude of the sound needs to enable the target object to produce a corresponding reaction, which includes but is not limited to: moving in a preset direction upon hearing the sound; or moving in the direction of the sound upon hearing the sound, etc. Therefore, the magnitude of the sound can be set according to the reaction of the target object, and is not specifically limited here.

[0056] In one embodiment, the external force that enables the sound generating mechanism 2 to generate sound is a human force, that is, the breeder slaps the rod body 1 so that the sound generating mechanism 2 in the rod body 1 vibrates to generate sound.

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

[0058] Therefore, in another embodiment, the rod body 1 of the pig driving stick 100 is further provided with an airflow channel 15, and the airflow channel 15 is provided on the gripping portion 11 and / or the driving portion 12. The first air inlet 151 of the airflow channel 15 is communicated with the airflow generating mechanism 4, and the first air outlet 152 of the airflow channel 15 is communicated with the accommodating chamber 13. The airflow generated by the airflow generating mechanism 4 flows into the accommodating chamber 13 through the airflow channel 15, so that the sound generating mechanism 2 makes a sound.

[0059] The airflow channel 15 is parallel or tends to be parallel to the accommodating chamber 13, and "tends to be parallel" means that the airflow channel 15 and the accommodating chamber 13 are arranged in parallel to the naked eye. By arranging the airflow channel 15 and the accommodating chamber 13 to be parallel or tend to be parallel, the airflow in the airflow channel 15 can be directly directed to the accommodating chamber 13, so that the flow velocity loss of the airflow is minimized, so as to ensure the intensity of the sound finally emitted by the sound generating mechanism 2.

[0060] The airflow generating mechanism 4 can be an external air pump. In this case, the air pump is connected to the first air inlet 151 of the airflow channel 15 through a connecting pipe, so that the gas after the air pump is running is transported to the airflow channel 15 through the connecting pipe. The operating power of the air pump is adjustable, so as to control the flow rate of the airflow entering the airflow channel 15 accordingly. At this time, there is no limit on the working time of the airflow generating mechanism 4, and the air pump can be connected to the mains or a corresponding power supply to work.

[0061] Alternatively, in another embodiment, the airflow generating mechanism 4 can be directly connected to the rod body 1 to facilitate the breeder to move the pig driving stick 100 by hand without limiting the breeder's range of movement.

[0062] The airflow generating mechanism 4 is rotatably connected to the rod body 1, and the rod body 1 is provided with a piercing member 17. When the airflow generating mechanism 4 is connected to the rod body 1, the piercing member 17 pierces the third air outlet 41 of the airflow generating mechanism 4. In this embodiment, the airflow generating mechanism 4 is rotatably connected to the handgrip portion 11. That is, the airflow generating mechanism 4 and the driving portion 12 are respectively arranged at both ends of the handgrip portion 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 rotational connection between the airflow generating mechanism 4 and the rod body 1 is a threaded connection. The piercing member 17 is an object with a pointed end, and the pointed end is arranged toward the third air outlet 41 of the airflow generating mechanism 4. When the airflow generating mechanism 4 and the rod body 1 are rotated to be tightly connected, the pointed end pierces the third air outlet 41 of the airflow generating mechanism 4.

[0064] The rod body 1 also has a communication channel 16 connecting the airflow channel 15 and the third air outlet 41, and the piercing member 17 is disposed in the communication channel 16. In addition, the rod body 1 includes a support member 111 disposed in the communication channel 16, and the piercing member 17 is connected to the support member 111. The support member 111 is in a cross shape or a straight shape. In this embodiment, the communication channel 16 is disposed in the handshake portion 11, and the communication channel 16 is also parallel or tends to be parallel to the accommodating cavity 13 to avoid reducing the flow speed of the airflow.

[0065] Moreover, in this embodiment, the airflow generating mechanism 4 is a handheld air pump, which itself has a battery pack, and the battery pack can power the air pump. When the power of the air pump is low or exhausted, the battery pack is taken out or the charging pump is directly charged.

[0066] The pig driving rod 100 further includes a valve mechanism 3, which is movably disposed at the first air inlet 151 of the air flow channel 15 to open or block the first air inlet 151, so as to connect or block the air flow generating mechanism 4 and the air flow channel 15. By providing the valve mechanism 3, the first air inlet 151 of the air flow channel 15 can be opened or closed, so as to control the sound generating mechanism 2, so that the sound generating mechanism 2 vibrates to make a sound, or stops to avoid making a 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 suitable for blocking or opening the first air inlet 151, and a lever 32 connected to the piston 31 to drive the piston 31 to move relative to the first air inlet 151 under the action of an external force. An action is applied to the lever 32 so that the lever 32 can move relative to the first air inlet 151, thereby opening or blocking the first air inlet 151.

[0068] In one embodiment, the lever 32 is movable relative to the first air inlet 151 , and the moving direction of the lever 32 is perpendicular or parallel to the flow direction of the airflow.

[0069] In another embodiment, the lever 32 can rotate relative to the first air inlet 151. In this case, the rod body 1 also has a sliding cavity 14 connected to the first air inlet 151, the piston 31 is slidably disposed in the sliding cavity 14, and the lever 32 is rotatably disposed outside the sliding cavity 14. The lever 32 is driven to rotate by applying a force, so that the lever 32 drives the piston 31 to slide in the sliding cavity 14, and then the first air inlet 151 is blocked or opened. There is an angle between the extension line of the sliding cavity 14 and the extension line of the airflow channel 15. In this embodiment, the angle between the extension line of the sliding cavity 14 and the extension line of the airflow channel 15 is 90°. In other embodiments, the angle between the extension line of the sliding cavity 14 and the extension line of the airflow channel 15 can also be 75°, 30°, 45°, etc., which is not specifically limited here and depends on actual conditions.

[0070] The lever 32 is provided with a slide groove 321, and the slide groove 321 has a first end 322 and a second end 323 that are arranged opposite to each other. The connecting portion 311 of the piston 31 and the lever 32 is slidably connected with the slide groove 321. When an external force is applied to the lever 32 to move the lever 32, the connecting portion 311 slides between the first end 322 and the second end 323. When the connecting portion 311 is located at the first end 322 or when the connecting portion 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 blocks the first air inlet 151; the lowest position is the stop position where the lever 32 moves toward the direction close to the rod body 1 under the action of an external force; when the lever 32 rotates under the action of an external force to make the connecting portion 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: the lever 32 rotates to this position and cannot continue to rotate in the current rotation direction.

[0071] The valve mechanism 3 further includes a first elastic member 33 sleeved on the piston 31; when the piston 31 blocks the first air inlet 151, the first elastic member 33 is in an initial state; an external force is applied to the lever 32 to drive the piston 31 to move so as to open the first air inlet 151, and the first elastic member 33 is compressed. When the external force is removed, the first elastic member 33 recovers under its elastic force so as to move the piston 31 to the initial position. In this embodiment, the first elastic member 33 is a spring.

[0072] As can be seen from the above, the rod body 1 also has a communication channel 16 arranged parallel or parallel to the airflow channel 15, the second air inlet 161 of the communication channel 16 is connected to the airflow generating mechanism 4, and the second air outlet 162 is connected to the sliding cavity 14. When the piston 31 blocks the first air inlet 151, it also blocks the second air outlet 162; when the connecting portion 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 includes a sound generating member 21 disposed in the accommodating chamber 13, a sliding member 22 slidably disposed in the sliding chamber 14, and a rotating member 23 connecting the sound generating member 21 and the sliding member 22, wherein the sliding member 22 is disposed opposite to the piston 31. The second air outlet 162 is disposed offset from the first air inlet 151, and the diameter of the second air outlet 162 is larger than the diameter of the first air inlet 151, so that the airflow flowing out of the second air outlet 162 is gathered in the sliding chamber 14, and the airflow velocity flowing into the airflow channel 15 is increased. At the same time, it can also provide a force for the sliding of the sliding member 22, so that the sliding member 22 moves in a direction away from the piston 31 under the action of the gathered airflow, and then drives the rotating member 23 to rotate. The sliding member 22 is essentially the same as the piston 31, and also plays a blocking role.

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

[0075] The sound generating member 21 includes a rope 211 connected to the rotating member 23 and a vibrating sound piece 212 connected to the rope 211. The sliding member 22 slides to drive the rotating member 23 to rotate, thereby driving the rope 211 to be tight and causing the vibrating sound piece 212 to vibrate and make a sound. That is, when the rotating member 23 does not rotate, the rope 211 is in a relaxed state. When the rotating member 23 rotates under the action of the sliding member 22, the rope 211 is pulled and becomes tight.

[0076] The sound generating mechanism 2 further includes a second elastic member 24, which is disposed on the sliding member 22. The second elastic member 24 has the same function as the first elastic member 33, and will not be described in detail herein. Similarly, the second elastic member 24 is a spring.

[0077] The present invention also provides a pig-driving device, comprising a support frame and a pig-driving rod 100, wherein the support frame has a plurality of engaging parts, and the pig-driving rod 100 engages with the engaging parts to be placed on the support frame. When it is needed, an external force is applied to the pig-driving rod 100 and / or the support frame to separate the pig-driving rod 100 from the support frame.

[0078] The support frame is also provided with an air pumping mechanism, which is used to pump air for the airflow 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 air pumping mechanism can be connected to the third air inlet of the airflow generating mechanism 4 to pump air. The air pumping mechanism is a conventional structure, such as an air pump, etc., which is not specifically limited here and is determined according to actual conditions.

[0079] In summary: by providing a rod body 1, a sound generating mechanism 2 and a valve mechanism 3, a accommodating chamber 13 and an airflow channel 15 connected to the accommodating chamber 13 are provided in the rod body 1, and at the same time, the airflow channel 15 is connected to the airflow generating mechanism 4, so that the airflow generated by the airflow generating mechanism 4 can flow into the accommodating chamber 13 through the airflow channel 15, so that the sound generating mechanism 2 arranged in the accommodating chamber 13 makes a sound, thereby achieving the effect of driving pigs away; 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 then controlling whether the sound generating mechanism 2 is generated, which is convenient and quick, and there is no need to apply external force, and the movement of the sound generating mechanism 2 is directly driven by the impact of the airflow; and, there is no need to make the pig-driving rod 100 act on the pig, and no bruises will be generated on the pig to affect the pig itself.
