Pork is an important source of animal protein and other nutrients, and its market demand has been growing steadily. Sows have strong reproductive capacity and are an indispensable breeding mother in animal husbandry. A healthy three-way hybrid sow can produce 2.2 to 2.5 litters per year, providing a large number of reserve pigs for animal husbandry.

[0003] Feed troughs are essential equipment in pig farms. They are mainly used to hold and feed pigs to ensure that they can get enough nutrition. Pigs have a natural habit of digging for food. In the wild, they will dig in the soil to find food. However, in a captive environment, this habit may cause pigs to dig in the feed trough, especially after giving birth, sows become emotionally agitated due to physiological discomfort or changes in hormone levels, and the situation of digging in the trough is even worse. In order to extend the service life of the feed trough, existing sow feed troughs are often equipped with reinforcement devices on their surface. However, it is difficult to alleviate the sow's irritability or bad behavior through such simple reinforcement. Therefore, simple reinforcement of the feed trough is only a temporary solution and does not provide a fundamental solution, and the protection effect of the feed trough is poor.

[0032] 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.

[0033] See also Figure 1-6 The present invention provides a technical solution: a reinforcing device for a sow trough in a delivery room, comprising a trough frame 1 and a Z-shaped plate 2 fixedly connected to the inner wall of the trough frame 1. The arrangement of the Z-shaped plate 2 makes the inner wall of the trough frame 1 and the left side of the Z-shaped plate 2 form a funnel shape, which is convenient for feeding feed. A partition 33 fixedly connected to the lower part of the right side of the Z-shaped plate 2 is fixedly connected to the inner bottom wall of the trough frame 1. The arrangement of the partition 33 reinforces the lower part of the Z-shaped plate 2 and also plays a role in dividing food for the device. A fixed plate 27 is fixedly connected to the lower part of the outer surface of the trough frame 1. A reinforcing rib 28 is fixedly connected to the connection between the fixed plate 27 and the trough frame 1. The coordinated arrangement of the fixed plate 27 and the reinforcing rib 28 makes the bottom surface structure of the trough frame 1 more stable. A group of fixing rods 29 fixedly connected to the left side of the type plate 2 are fixedly connected to the inner wall of the food trough frame 1. The setting of the fixing rods 29 makes the structure of the Z-shaped plate 2 more stable. A group of fixing holes 32 are opened on the inner wall of the food trough frame 1. The fixing holes 32 are convenient for further fixing the food trough frame 1 by bolts. A pair of abutment plates 3 are arranged on the right side of the Z-shaped plate 2. Two groups of limiting rods 4 fixedly connected to the left sides of the two abutment plates 3 all penetrate the Z-shaped plate 2 to the left side of the Z-shaped plate 2, and a group of telescopic springs 12 are fixedly connected to the left sides of the two abutment plates 3. The setting of the limiting rods 4 enables the abutment plates 3 to move horizontally after being subjected to force. The left end of the telescopic spring 12 is fixedly connected to the right side of the Z-shaped plate 2. The setting of the telescopic spring 12 plays a role of buffering and resetting the abutment plates 3.

[0034] A pair of piston cylinders 5 are embedded in the lower part of the right side of the Z-shaped plate 2. The two piston cylinders 5 are connected to the liquid collecting cylinder 6 fixedly connected to the right side of the food trough frame 1 through the first one-way valve 7. The upper surface of the liquid collecting cylinder 6 is hinged with a cylinder cover 30. The front of the cylinder cover 30 is provided with an observation window 31. The opening of the observation window 31 is convenient for observing the residual amount of pheromone solution in the liquid collecting cylinder 6. The piston rods 8 slidably connected to the inner walls of the two piston cylinders 5 are connected to the nozzles 9 embedded in the right side of the plate 3. The outer surface of the plate 3 is fixedly connected The rubber layer 23 is fixedly connected to the right side of the Z-shaped plate 2, the limit rod 4, the right end of the piston rod 8 and the telescopic spring 12 are all located inside the rubber layer 23, the limit rod 4 is slidably connected to the penetration of the Z-shaped plate 2, and the rubber layer 23 protects the limit rod 4, the piston rod 8 and the telescopic spring 12. The connection between the two piston rods 8 and the nozzle 9 is provided with a first check valve 10 and a second check valve 11. The liquid inlet end of the first check valve 10 is connected to the liquid outlet end of the first one-way valve 7, and the first check valve 10 is connected to the liquid outlet end of the first one-way valve 7. The liquid outlet end of the valve 10 is connected to the liquid inlet end of the second check valve 11, the liquid outlet end of the second check valve 11 is connected to the inside of the nozzle 9, the liquid inlet end of the first check valve 7 is connected to the liquid outlet end of the second check valve 22 embedded in the bottom wall of the liquid collecting cylinder 6, and the liquid inlet end of the second check valve 22 is connected to the inside of the liquid collecting cylinder 6, which ensures the flow direction of the pheromone solution added to the piston cylinder 5, that is, when the sow is agitated and keeps arching the feeding trough, the back plate 3 keeps moving left and right, and the piston rod 8 moves in the back plate 3. Under the action, the inner wall of the piston cylinder 5 moves left and right, so that the pheromone solution in the liquid collecting cylinder 6 is sprayed to the outside through the second one-way valve 22, the first one-way valve 7, the piston cylinder 5, the first check valve 10, the second check valve 11 and the nozzle 9. Pheromones have the effect of influencing and improving the emotional state of animals and relieving anxiety, thereby alleviating sows from emotional agitation or bad behavior, and indirectly protecting the sow feed trough. A point switch 13 is provided on the left side of the upper limit rod 4 in the two groups.

[0035] An ultrasonic generator 14 electrically connected to two moment switches 13 is fixedly connected to the right side of the Z-shaped plate 2, and a pair of threaded cylinders 15 are fixedly connected to the left side of the trough rack 1. The inner walls of the two threaded cylinders 15 are threadedly connected with threaded rods 16, and the left ends of the two threaded rods 16 are fixedly connected with transmission wheels 24. The two transmission wheels 24 are connected by belts 25 for transmission, and the left sides of the two transmission wheels 24 are fixedly connected with cross rotating wheels 26. The matching arrangement of the transmission wheels 24 and the belts 25 enables the two threaded rods 16 to rotate synchronously. The moving blocks 17 rotatably connected to the right ends of the two threaded rods 16 are fixedly connected to a moment switch 13, and the moving blocks 17 and the moment switch 13 can be driven to move left and right by rotating the threaded rods 16. The two protective cylinders 18 fixedly connected to the left side of the Z-shaped plate 2 are both embedded in the inner wall of the trough rack 1, and the upper limit rods 4 in the two groups extend to one respectively. Inside the protective tube 18, and the left ends of the two limit rods 4 are fixedly connected with a rubber block 21 adapted to the moment switch 13. When the rubber block 21 contacts the moment switch 13, the ultrasonic generator 14 is energized and started. Similarly, when the rubber block 21 does not contact the moment switch 13, the ultrasonic generator 14 loses power and does not start. The setting of the protective tube 18 protects the left and right movement of the upper limit rod 4, the moving block 17 and the moment switch 13, and prevents the feed in the funnel-shaped interior formed inside the trough rack 1 and the left side of the Z-shaped plate 2 from affecting the moment setting of the device. A group of slide grooves 19 are opened on the inner walls of the two protective tubes 18, and the sliders 20 slidably connected to the inner walls of the two groups of slide grooves 19 are respectively fixedly connected to the outer surface of a moving block 17. The matching setting of the slide grooves 19 and the sliders 20 limits the moving block 17, so that the moving block 17 moves horizontally left and right when the threaded rod 16 is rotated.

[0036] For sows with poor pheromone relief effects, the cross wheel 26 is rotated so that the two threaded rods 16 rotate synchronously under the coordinated setting of the transmission wheel 24 and the belt 25, thereby driving the right end of the moving block 17 and the inching switch 13 to move left and right inside the protective tube 18, and adjusting the initial distance between the inching switch 13 and the rubber block 21, so as to adjust the force when the rubber block 21 set at the left end of the limit rod 4 contacts the inching switch 13 when the abutment plate 3 moves left, that is, when the moving block 17 drives the inching switch 13 to move left, the rubber block 21 is far away from the inching switch 13, and the sow needs to hit with a larger force to drive the rubber block 21 to contact the inching switch 13. On the contrary, the sow needs to hit with a smaller force to drive the rubber block 21 to contact the inching switch 13. The impact of the abutment plate 3 causes the normally open main contact inside the inching switch 13 to close, and the ultrasonic generator 14 is started. The ultrasonic wave generated automatically drives the sow away, and further protects the feed trough.

[0037] Working principle: When in use, connect the ultrasonic generator 14 to the power supply, add a proper amount of pheromone solution into the liquid collecting cylinder 6, when the sow is agitated and keeps arching the trough, the plate 3 is constantly moved left and right, and the piston rod 8 moves left and right on the inner wall of the piston cylinder 5 under the action of the plate 3, so that the pheromone solution in the liquid collecting cylinder 6 is sprayed to the outside through the second one-way valve 22, the first one-way valve 7, the piston cylinder 5, the first check valve 10, the second check valve 11 and the nozzle 9, and the pheromone is used to influence and improve the emotional state of the animal and relieve anxiety, thereby alleviating the sow's agitation or bad behavior, indirectly protecting the sow's trough, and having no effect on the relief of pheromones. For the best sow, rotate the cross wheel 26 so that the two threaded rods 16 rotate synchronously under the cooperation of the transmission wheel 24 and the belt 25, thereby driving the right end of the moving block 17 and the moment switch 13 to move left and right inside the protective tube 18, and adjusting the initial distance between the moment switch 13 and the rubber block 21, thereby adjusting the force when the rubber block 21 set at the left end of the limit rod 4 contacts the moment switch 13 when the plate 3 moves left, so that after the plate 3 is hit, the impact of the plate 3 causes the normally open main contact inside the moment switch 13 to close, and the ultrasonic generator 14 is started, and the ultrasonic wave generated has the effect of automatically driving the sow away, and further protects the feed trough.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
