Description

Technical Field

[0001] This utility model relates to the field of pig weighing equipment, and in particular to an automatic limit device for weighing pigs. Background Technology

[0002] Pig farming is an important part of animal husbandry, and body weight is an important indicator for measuring the growth and health of pigs. The traditional method of weighing pigs usually involves driving them to a fixed weighing area and weighing them manually using electronic scales. Currently, traditional pig weighing devices rely on manual operation and require driving pigs to a specific weighing area. However, these devices lack limiting devices, and the large space available for piglets in the weighing area causes them to move around frequently, affecting measurement accuracy. Traditional pig weighing devices are unable to meet the simultaneous weighing needs of piglets and fattening pigs. Utility Model Content

[0031] Please refer to Figures 1 to 2 This utility model provides an automatic limiting device for weighing pigs, including a weighing platform 2, a weighing frame 1, a weighing sensor 3, and a limiting mechanism 4.

[0032] The limiting mechanism 4 includes a first electric push rod 46 and a folding plate 41;

[0033] The weighing frame 1 is provided with a weighing hole;

[0034] The weighing platform 2 is disposed in the weighing hole, and one end of the top of both sides of the weighing platform 2 is connected to the inner wall of the weighing frame 1 through the weighing sensor 3.

[0035] The folding plates 41 are provided on both sides of the inner wall of the weighing platform 2;

[0036] Both ends of the folding plate 41 are connected to control rods 42. The upper and lower ends of the control rod 42 at the tail of the folding plate 41 are rotatably connected to the inner wall of the weighing platform 2. The top end of the control rod 42 at the head of the folding plate 41 is connected to the push rod of the first electric push rod 46, and the bottom end of the control rod 42 at the head of the folding plate 41 is connected to a roller 47.

[0037] In use, live pigs are driven onto the weighing platform 2, and the weight information of the live pigs is obtained through the weighing sensor 3. When fattening pigs enter the weighing platform 2, the push rod of the first electric push rod 46 retracts, so that the folding plate 41 is in a flat state, expanding the weighing space in the weighing platform 2 to meet the weighing needs of fattening pigs. When piglets enter the weighing platform 2, the first electric push rod 46 drives the push rod to move outward, so that the folding plate 41 is in a bent state, reducing the weighing space in the weighing platform 2 to meet the weighing needs of piglets. This application has a high degree of automation, is easy to use, and can meet the weighing needs of both piglets and fattening pigs at the same time, making it suitable for large-scale promotion and use.

[0038] In this embodiment, the inner wall of the weighing platform 2 is provided with a guide plate 45, and the guide plate 45 is provided with a guide hole corresponding to the movement trajectory of the control rod 42 at the head of the folding plate 41.

[0039] In this embodiment, the folding plate 41 includes at least three limiting plates that are hinged end to end. The hinged portion of the limiting plate located in the middle is rotatably connected to one end of a connecting rod 43. The other end of the connecting rod 43 is fixedly connected to a limiting rod 44. The upper and lower ends of the limiting rod 44 are rotatably connected to the inner wall of the weighing platform 2. The connecting rod 43 and the limiting rod 44 can prevent the folding plate 41 from bending towards the inner wall of the weighing platform 2.

[0040] In this embodiment, access control mechanisms 5 are provided at both the entrance and exit of the weighing frame 1. The access control mechanism 5 includes a gate 56 and a drive assembly. The gate 56 has two panels, and a pivot 55 is provided on the side of the two gates 56 that are far apart from each other. The gate 56 is connected to the weighing frame 1 through the pivot 55. The drive assembly is connected to the pivot 55. The drive assembly includes a second electric push rod 51, a V-shaped rod 52, a first drive rod 53, and a second drive rod 54. The push rod of the second electric push rod 51 is connected to the bent part of the V-shaped rod 52. The two free ends of the V-shaped rod 52 are respectively rotatably connected to one end of the first drive rod 53. The other end of the first drive rod 53 is rotatably connected to the second drive rod 54. The end of the second drive rod 54 that is far away from the first drive rod 53 is fixedly connected to the pivot 55.

[0041] In use, the second electric push rod 51 drives the V-shaped rod 52 to move. With the cooperation of the first drive rod 53 and the second drive rod 54, the rotating shaft 55 is controlled to rotate, thereby controlling the opening and closing of the two fence gates 56.

[0042] The working principle of this utility model is as follows:

[0043] The pigs are driven onto the weighing platform 2, and the weight information of the pigs is obtained by the weighing sensor 3. When the fattening pigs enter the weighing platform 2, the push rod of the first electric push rod 46 retracts, so that the folding plate 41 is in a flat state, expanding the weighing space in the weighing platform 2 to meet the weighing needs of the fattening pigs. When the piglets enter the weighing platform 2, the first electric push rod 46 drives the push rod to move outward, so that the folding plate 41 is in a bent state, reducing the weighing space in the weighing platform 2 to meet the weighing needs of the piglets. This application has a high degree of automation, is easy to use, and can meet the weighing needs of both piglets and fattening pigs at the same time, making it suitable for large-scale promotion and use.
