Description

Technical Field

[0001] The utility model relates to the technical field of pig breeding equipment, in particular to a pig breeding semi-limited fence. Background Art

[0002] Modern pig farming in my country is mainly based on intensive farming. This intensive production model of high density, high reproduction rate and rapid fattening brings many unscientific aspects. After conception, sows waiting to give birth are locked in the stalls, but the sows cannot move in the stalls and have poor resistance. If they are locked in ordinary large pens, they will fight and collide when eating. Semi-limited stalls have enough space for movement and avoid fighting for food during eating. The survival rate of sows and piglets is improved and the disease rate is reduced.

[0003] The patent document with the publication number "CN201640158U" discloses a semi-limited fence for pregnant sows to eat, including a front fence of the fence and a feeding trough installed under the front fence of the fence. The main fence of the semi-limited fence is installed behind the front fence of the fence, and multiple main fences are evenly distributed along the front fence of the fence; the front fence of the fence, the feeding trough and the front end of the semi-limited fence are installed on a feeding table higher than the ground of the fence; a movable railing is installed behind the semi-limited fence. The semi-limited fence avoids the various disadvantages of using a full-limited fence. In the free-range mode, it can effectively isolate and position each pregnant sow during feeding, avoid fighting among pregnant sows for food, and realize scientific and efficient management of feeding. It is also hygienic and convenient to eat, easy to rinse, and easy to operate.

[0004] In the above-mentioned prior art, the movable bars of the semi-confining fence need to be opened and closed manually to prevent the pigs from being disturbed by other pigs during the eating process, which increases the intensity of manual labor; at the same time, manual labor is required to always pay attention to the eating conditions of the pigs and promptly open the closed bars of the confining fence where the pigs have finished eating. However, there is inevitably a certain lag in manual operation, which causes some pigs to be unable to leave the feeding place in time after eating, which may cause the pigs to become restless and may even cause the pigs to overreact (such as hitting the bars, etc.), affecting their healthy growth. Therefore, semi-confining fences are needed for pig farming. Utility Model Content

[0005] The purpose of this application is to provide a semi-confined stall for pig farming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a semi-limited fence for pig farming, comprising a main fence, a plurality of limit fences vertically fixed to the main fence are arranged on the rear side of the main fence, a semi-open feeding space is formed between two adjacent limit fences, a feeding trough is arranged on the rear side of the main fence, and a feeding port corresponding to the position of the feeding trough is opened in the middle of the main fence;

[0007] A support frame is fixed to the upper end of the side of two adjacent limit railings away from the main railing, a vertically extending slide groove is provided on the inner side of the support column of the support frame, a movable railing is slidably connected in the slide groove, and a reset piece is provided on the upper end of the movable railing;

[0008] A trigger plate that slides up and down is installed at the end of the feeding trough away from the main railing;

[0009] Follower assemblies are installed on both sides of the trigger plate. When the trigger plate slides downward, the movable railing is driven to descend to the middle between the two limit railings through the follower assembly.

[0010] Preferably, the driven assembly includes a driven rack, a driven gear and a winding reel, the driven rack is fixed to the side wall of the trigger plate, the driven rack is meshed with the driven gear, the winding reel and the driven gear are coaxially fixed through a connecting shaft, the other side of the winding reel is rotatably connected to the limiting railing, a traction rope is wound around the winding reel, the end of the traction rope away from the winding reel passes through the lower end of the limiting railing, extends upward and is fixed to the lower end of the movable railing.

[0011] Preferably, the diameter of the winding drum is 3-6 times the diameter of the driven gear, and the driven gear is driven to rotate at least two circles when the driven rack is raised or lowered.

[0012] Preferably, the reset member comprises a tension spring, and the upper and lower ends of the tension spring are respectively fixed to the bottom of the cross bar of the support frame and the upper end of the movable railing.

[0013] Preferably, a plurality of evenly distributed compression springs are fixed to the lower end of the trigger plate, and the lower ends of the compression springs are fixed on the ground.

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] 1. In the utility model, through the arrangement of the movable railing, the trigger plate, the driven component and the reset member, after the pig enters the feeding space between the two limit railings, the pig approaches the feeding trough forward and steps on the trigger plate to make the trigger plate descend. At this time, the trigger plate drives the movable railing to descend to the middle between the two limit railings through the driven component, thereby temporarily blocking the rear side of the feeding space to prevent other pigs from interfering with the pig while it is eating. When the pig finishes eating, the pig retreats and leaves the trigger plate. At this time, the driven component loses its driving effect, so that the movable railing is reset under the action of the reset member, that is, it rises to the middle of the support frame, thereby opening the feeding space again, so that the pig that has finished eating can leave the feeding space;

[0017] Compared with the existing manual opening and closing, the semi-automatic opening and closing is more convenient to use and does not require manual management, reducing the intensity of manual labor. At the same time, each pig can freely enter and exit the feeding space, avoiding the pig's inability to leave in time after eating and affecting other pigs' eating. At the same time, it avoids the pig's restlessness caused by staying in the feeding space for too long, which is conducive to the healthy growth of the pig.

[0018] 2. In the utility model, by setting the compression spring, when the trigger plate loses the pressure of the pig, the elastic force of the compression spring causes the trigger plate to automatically reset, so that it is convenient to drive the movable railing to descend again when the next pig enters.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: Reference Figure 1-4The semi-limited fence for pig farming shown in the figure comprises a main rail 1, a plurality of limit rails 2 vertically fixed to the main rail 1 are arranged at the rear side of the main rail 1, a semi-open feeding space is formed between two adjacent limit rails 2, a feeding trough 4 is arranged at the rear side of the main rail 1, and a feeding port 3 corresponding to the position of the feeding trough 4 is opened in the middle of the main rail 1;

[0027] A support frame 5 is fixed to the upper end of the side of two adjacent limit railings 2 away from the main railing 1, and a vertically extending slide groove 51 is provided inside the support column of the support frame 5. A movable railing 6 is slidably connected in the slide groove 51, and a reset member is provided at the upper end of the movable railing 6;

[0028] A trigger plate 8 that slides up and down is installed at one end of the feeding trough 4 away from the main railing 1;

[0029] Follower components 9 are installed on both sides of the trigger plate 8. When the trigger plate 8 slides downward, the movable railing 6 is driven by the follower component 9 to descend to the middle between the two limit railings 2.

[0030] Based on the above structure, after the pig enters the feeding space between the two limiting rails 2, the pig approaches the feeding trough 4 forward and steps on the trigger plate 8 to make the trigger plate 8 descend. At this time, the trigger plate 8 drives the movable rail 6 to descend to the middle between the two limiting rails 2 through the driven component 9, thereby temporarily blocking the rear side of the feeding space to prevent other pigs from interfering with the pig when it is eating. When the pig finishes eating, the pig retreats and leaves the trigger plate 8. At this time, the driven component 9 loses its driving effect, so that the movable rail 6 is reset under the action of the reset member, that is, it rises to the middle of the support frame 5, thereby opening the feeding space again, so as to facilitate the pig that has finished eating to leave the feeding space;

[0031] Compared with the existing manual opening and closing, the semi-automatic opening and closing is more convenient to use and does not require manual management, reducing the intensity of manual labor. At the same time, each pig can freely enter and exit the feeding space, avoiding the pig's inability to leave in time after eating and affecting other pigs' eating. At the same time, it avoids the pig's restlessness caused by staying in the feeding space for too long, which is conducive to the healthy growth of the pig.

[0032] Among them, the driven component 9 includes a driven rack 91, a driven gear 92 and a winding drum 93. The driven rack 91 is fixed to the side wall of the trigger plate 8, the driven rack 91 is meshed with the driven gear 92, the winding drum 93 and the driven gear 92 are coaxially fixed through a connecting shaft, and the other side of the winding drum 93 is rotatably connected to the limiting railing 2. A traction rope 94 is wound around the winding drum 93, and the end of the traction rope 94 away from the winding drum 93 passes through the lower end of the limiting railing 2 and then extends upward and is fixed to the lower end of the movable railing 6.

[0033] When the trigger plate 8 descends, the driven rack 91 is driven to descend synchronously, and when the driven rack 91 descends, it drives the driven gear 92 meshing with it to rotate, thereby driving the winding reel 93 to rotate synchronously, so that the traction rope 94 is wound up, and when the traction rope 94 is wound up, it pulls the movable railing 6 down, thereby achieving the purpose of semi-automatically driving the movable railing 6 to descend and isolating the feeding space at that location.

[0034] Among them, the diameter of the winding drum 93 is 3-6 times the diameter of the driven gear 92, so that the winding drum 93 can reel in more traction rope 94 under the drive of the driven gear 92, and the driven rack 91 drives the driven gear 92 to rotate at least two circles when it is raised and lowered, thereby ensuring that the movable railing 6 can be lowered to a sufficient height, so that the movable railing 6 can be lowered to the middle between the two limit railings 2 to play an isolation role.

[0035] Among them, the reset part includes a tension spring 7, the upper and lower ends of the tension spring 7 are respectively fixed to the bottom of the cross bar of the support frame 5 and the upper end of the movable railing 6. When the pig leaves the trigger plate 8, the trigger plate 8 loses control of the driven rack 91. At this time, the movable railing 6 is not affected by the tension of the traction rope 94, and at the same time rises under the elastic force of the tension spring 7, thereby rising to the middle part of the support frame 5, so that the opening of the feeding space is opened, which is convenient for the pigs to leave the feeding space after eating.

[0036] Among them, a plurality of evenly distributed compression springs 82 are fixed to the lower end of the trigger plate 8, and the lower end of the compression spring 82 is fixed to the ground. When the trigger plate 8 loses the pressure of the pig, the elastic force of the compression spring 82 causes the trigger plate 8 to automatically reset, thereby facilitating the movable railing 6 to descend again when the next pig enters.

[0037] Among them, the side of the trigger plate 8 away from the feeding trough 4 is rotatably connected to a tilted movable pedal 81, and the end of the movable pedal 81 away from the trigger plate 8 is overlapped on the ground, so as to prevent the pigs from kicking at the edge of the trigger plate 8 and damaging the edge of the trigger plate 8, and at the same time can guide the pigs to step on the trigger plate 8, playing a guiding role.

[0038] The working principle of the utility model is as follows: in daily use, after the pig enters the feeding space between the two limit rails 2, the pig approaches the feeding trough 4 forward and steps on the trigger plate 8, so that the trigger plate 8 descends. At this time, the trigger plate 8 drives the driven rack 91 to descend synchronously. When the driven rack 91 descends, it drives the driven gear 92 meshing with it to rotate, thereby driving the winding drum 93 to rotate synchronously, so that the traction rope 94 is wound up. When the traction rope 94 is wound up, the movable rail 6 is pulled down, so that the movable rail 6 descends to the middle part between the two limit rails 2, thereby temporarily blocking the rear side of the feeding space to prevent other pigs from interfering with it when the pig is eating. When the pig finishes eating, the pig retreats and leaves the trigger plate 8. At this time, the trigger plate 8 loses control of the driven rack 91. At this time, the movable rail 6 is not affected by the pulling force of the traction rope 94, and at the same time rises under the elastic force of the tension spring 7, thereby rising to the middle part of the support frame 5, thereby opening the feeding space again, so as to facilitate the pigs who have finished eating to leave the feeding space;

[0039] At the same time, when the trigger plate 8 loses the pressure of the pig, the elastic force of the compression spring 82 causes the trigger plate 8 to automatically reset, so that it can drive the movable railing 6 to descend again when the next pig enters;

[0040] Compared with the existing manual opening and closing, the semi-automatic opening and closing is more convenient to use and does not require manual management, reducing the intensity of manual labor. At the same time, each pig can freely enter and exit the feeding space, avoiding the pig's inability to leave in time after eating and affecting other pigs' eating. At the same time, it avoids the pig's restlessness caused by staying in the feeding space for too long, which is conducive to the healthy growth of the pig.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
