Description

Technical Field

[0001] This utility model relates to the field of estrus detection technology, specifically an estrus detection vehicle that can detect estrus in sows. Background Technology

[0002] With the continuous development of the pig farming industry, boar estrus detection vehicles have been widely used. Boar estrus detection vehicles are a pig farming tool that optimizes sow breeding and stimulates estrus. Its advantages include low maintenance costs, single-person operation and remote control, and flexible steering function that makes it easy to navigate various pig farms.

[0003] The existing patent (CN218245119U) describes a boar estrus detection vehicle, which includes a rear vehicle, casters, and a front vehicle. A channel is hinged to one side of the rear vehicle, and a reinforcing structure is provided at the top of the channel. Both ends of the bottom of the rear vehicle are equipped with pulleys. The front vehicle is hinged to one side of the rear vehicle. Limiting grooves are evenly installed on one side of the top of the front vehicle. A limiting structure is provided inside the limiting groove. The limiting structure includes a limiting rod, a support block, and a handle. The limiting rod is installed inside the limiting groove. A support block is installed at the top of the limiting rod, and a handle is installed at the top of the support block. Both ends of the bottom of the front vehicle are equipped with casters.

[0004] This technical solution uses evenly spaced limiting grooves on one side of the front vehicle's top. By inserting limiting rods into these grooves at different positions, the turning angle between the rear and front vehicles can be limited, thus allowing the boar estrus detection vehicle to move freely in various pig farms. However, determining whether a sow is in estrus during movement requires experienced workers to make judgments based on their expertise. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an estrus detection vehicle capable of detecting estrus in sows, thus solving the problems mentioned in the background art.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an estrus detection vehicle for detecting sows' estrus, comprising a movable frame and a fence above the frame. A fixed frame is fixedly installed on one side of the fence above the frame, extending above the fence. A horizontal telescopic mechanism is fixedly installed above the fixed frame. A vertical telescopic mechanism is fixedly installed below the free end of the horizontal telescopic mechanism. A pressing mechanism for pressing the sow's back is fixedly installed at the bottom end of the vertical telescopic mechanism. When the vertical telescopic mechanism extends or retracts, the pressing mechanism can pass laterally through the pen wall where the sows are kept.

[0008] Furthermore, the pressing mechanism includes a connecting sleeve, which is fixedly installed at the free end of the vertical telescopic mechanism. Opposite moving brackets are slidably connected to both sides of the connecting sleeve, and a pressure roller is rotatably connected to the bottom end of the bracket.

[0009] Furthermore, the fence includes a rectangular air-permeable grille, one side of which can rotate relative to the other sides. The rotatable grille section is fixedly mounted with a fixed shaft, and a baffle is rotatably connected to the outer surface of the fixed shaft. The non-rotatable grille section is fixedly mounted with a baffle groove, and the baffle can be rotated and engaged inside the baffle groove.

[0010] Furthermore, the frame is rotatably connected to a ramp plate whose bottom end contacts the ground at a movable grille section. A telescopic sleeve is fixedly installed at the bottom end of the frame, and the free end of the telescopic sleeve can extend to the bottom of the ramp plate and squeeze the ramp plate to rotate away from the ground.

[0011] Furthermore, a support frame is fixedly installed at the bottom end of the ramp, and the bottom end of the support frame contacts the ground when the ramp contacts the ground.

[0012] Furthermore, the side wall of the fixed frame is fixedly equipped with a support diagonal rod, which is divided into two groups. One group is fixedly connected to the fixed end of the transverse telescopic mechanism, and the other group is slidably connected below the free end of the transverse telescopic mechanism.

[0013] Furthermore, a fan is fixedly installed on one side of the fence, which blows the air inside the fence outward.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This estrus detection vehicle drives the breeding pigs into the pen and moves them through the aisles of the pen using a vehicle frame. The sows are induced to react by the scent and vocalizations emitted by the breeding pigs. When the vehicle reaches the sow, the horizontal telescopic mechanism extends and the support retracts, aligning the pressure wheel with the sow's hindquarters. The vertical telescopic mechanism then lowers the pressure wheel to squeeze the sow. When the sow does not move after being squeezed, indicating estrus behavior, the pen number is recorded. If the sow does not show signs of estrus, the device retracts the frame and moves forward to continue the estrus detection. This solves the problem of the lack of technical means to determine whether a sow is in estrus in existing estrus detection processes.

[0016] 2. This estrus detection vehicle has a fan fixedly installed on one side of the enclosure. The fan blows the air inside the enclosure outward. The fan is located on the side of the vehicle frame closest to the sow feeding pen and in front of the vehicle frame in the direction of travel. This setting can preferentially spread the pheromones of the breeding pigs to the pen of the sow that needs to be detected, thereby reducing the time required to attract the sow.

[0017] 3. This estrus detection vehicle has a frame located on a movable grid section that is rotatably connected to a ramp plate whose bottom end contacts the ground. A telescopic sleeve is fixedly installed at the bottom end of the frame. The free end of the telescopic sleeve can extend to the bottom of the ramp plate and squeeze the ramp plate to rotate and lift it off the ground. Since breeding pigs are relatively large, this setting makes it easier for them to enter the pen and lift the ramp plate to avoid friction with the ground. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] See Figure 1-4 A estrus detection vehicle for sows includes a movable frame 1 and a fence 2 above the frame 1. A fixing frame 3 is fixedly installed on one side of the fence 2 above the frame 1, extending above the fence 2. A horizontal telescopic mechanism 4 is fixedly installed above the fixing frame 3. A vertical telescopic mechanism 5 is fixedly installed below the free end of the horizontal telescopic mechanism 4. A pressing mechanism 6 for pressing the sow's back is fixedly installed at the bottom of the vertical telescopic mechanism 5. When the vertical telescopic mechanism 5 extends or retracts, the pressing mechanism 6 can pass horizontally through the pen wall where the sows are kept. The pressing mechanism 6 imitates the mounting action of a boar, and the sow's reaction is observed to determine whether the sow is in estrus.

[0025] The pressing mechanism 6 includes a connecting sleeve 601, which is fixedly installed on the free end of the vertical telescopic mechanism 5. The two sides of the connecting sleeve 601 are slidably connected to opposing support brackets 602. The movement of the support brackets 602 can be controlled by a hydraulic telescopic mechanism or an electromagnetic telescopic mechanism. The bottom end of the support bracket 602 is rotatably connected to a pressure roller 603. By setting the pressure roller 603, it can provide cushioning when pressing sows that are not in estrus and when the sows move to avoid injuring them.

[0026] The fence 2 includes a rectangular air-permeable grille 201. One side of the grille 201 can rotate relative to the other sides. The rotatable grille part is fixedly mounted with a fixed shaft 202. A baffle 203 is rotatably connected to the outer surface of the fixed shaft 202. The non-rotatable grille part is fixedly mounted with a baffle groove 204. The baffle 203 can rotate and engage inside the baffle groove 204. This configuration can drive the breeding pigs into the interior of the fence 2.

[0027] The frame 1 is rotatably connected to a ramp 101 whose bottom end contacts the ground at a movable grid section. A telescopic sleeve 102 is fixedly installed at the bottom end of the frame 1. The free end of the telescopic sleeve 102 can extend to the bottom of the ramp 101 and squeeze the ramp 101 to rotate away from the ground. Since the breeding pigs are relatively large, this setting makes it easier for the breeding pigs to enter the interior of the enclosure 2 and can lift the ramp 101 to avoid friction with the ground.

[0028] A support frame 103 is fixedly installed at the bottom of the ramp 101. The bottom of the support frame 103 contacts the ground when the ramp 101 contacts the ground. This arrangement can increase the strength of the ramp 101.

[0029] The side wall of the fixed frame 3 is fixedly installed with a support diagonal rod 301. The support diagonal rod 301 is divided into two groups. One group is fixedly connected to the fixed end of the transverse telescopic mechanism 4, and the other group is slidably connected to the lower part of the free end of the transverse telescopic mechanism 4. This arrangement can support the transverse telescopic mechanism 4 and prevent deformation due to the long cantilever length.

[0030] A fan 7 is fixedly installed on one side of the enclosure 2. The fan 7 blows the air inside the enclosure 2 outward. The fan 7 is located on the side of the frame 1 near the sow feeding pen and in front of the frame 1 in the direction of travel. This setting can preferentially spread the pheromones of the breeding pigs to the pen of the sow that needs to be checked for estrus, thereby reducing the time required to attract the sow.

[0031] In use, the breeding pig is driven into the interior of enclosure 2 and moved through the aisle of the enclosure by the frame 1. The sow is guided to react by the scent and vocalizations emitted by the breeding pig. When the pig is moved to the sow, the horizontal telescopic mechanism 4 extends and the support 602 retracts, so that the pressure wheel 603 is aligned with the sow's hindquarters. The vertical telescopic mechanism 5 works, and the pressure wheel 603 descends to squeeze the sow. When the sow does not move after being squeezed and shows signs of estrus, the enclosure number is recorded. When the sow does not show signs of estrus, the device retracts and the frame 1 moves forward to continue the estrus check. This solves the problem of lack of technical means to determine whether a sow is in estrus in the existing estrus check process.

[0032] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
