Description

Technical Field

[0001] The utility model relates to the technical field of breeding troughs, and more specifically, to a feed trough for pig breeding. Background Art

[0002] A live pig is a general term for all domesticated pigs, excluding breeding stock, that have not been slaughtered. Pigs are omnivorous animals. They generally refer to livestock. Their meat is edible, and their hide can be made into leather. They are fat, short-limbed, docile, adaptable, easy to raise, and reproduce quickly. They can be black, white, dark red, or spotted.

At present, people's demand for meat, eggs and milk is increasing. Among them, pork is one of the important animal foods on the table. Existing pig farms use feed troughs to feed pigs. When pigs need to be fed, operators need to manually put feed into the feed trough. Although this method can feed pigs, the manual feeding of feed will cause the amount of feed to be unstable, and the amount of feed cannot be adjusted according to the different growth stages of pigs. When too much feed is put in, it will cause feed waste, and when the amount of feed is too little, it will affect the growth of pigs, which brings inconvenience to the daily use of operators, so it needs to be improved.

[0037] When the gear 7 rotates, the gear 7 will drive the long rod 9 to move through the tooth plate 8, and then the long rod 9 will drive the three short rods 10 to move at the same time. Due to the limitation of the limit groove 6, the three short rods 10 will move to the right. At this time, the three extrusion blocks 11 will move to the right under the drive of the three short rods 10, and then the outer surface of the extrusion block 11 will push the moving plate 12, so that the moving plate 12 drives the first partition 13 to move to the right. At this time, the moving plate 12 will shorten the distance between the circular plate 15 and the circular plate 15 during the rightward movement, thereby reducing the volume between the moving plate 12 and the circular plate 15, thereby realizing the function of adjusting the amount of feed fed.

[0038] The driving mechanism includes:

[0039] A fixing frame 17, the back of which is fixedly connected to the front of the barrel 1;

The outer surface of the rotating shaft 21 is movably sleeved with the inner side of the right side of the barrel 1, and the other end of the rotating shaft 21 is fixedly sleeved with the inner side of the round rod 16.

[0043] When the first power motor 20 is running, the rotating shaft 21 will drive the three second partitions 14 to rotate through the three circular plates 15, and then the three second partitions 14 will drive the three moving plates 12 to rotate through the three first partitions 13. At this time, the feed located between the three moving plates 12 and the three circular plates 15 will move to the outside of the barrel 1 through the three discharge ports 4 during rotation.

[0044] A base 22 is fixedly mounted on the left and right sides of the barrel 1 , and an arc-shaped groove 23 is formed on the left side of the base 22 .

[0045] Due to the design of the arc-shaped groove 23, the object located therein will be limited.

[0046] Among them, a fixed block 24 is fixedly installed at the bottom end of the left side of the base 22, a second power motor 25 is fixedly installed on the back of the fixed block 24, and a short shaft 26 is fixedly sleeved on the other end of the output shaft of the second power motor 25, and the outer surface of the short shaft 26 is movably sleeved on the back of the fixed block 24.

[0047] When the second power motor 25 is running, the short shaft 26 will rotate.

[0049] When the short shaft 26 rotates, the screw 27 will rotate driven by the short shaft 26. Since the screw 27 is threadedly connected to the square block 28, the screw 27 will drive the square block 28 to move when it rotates. Since the square block 28 is movably connected to the inside of the fixed block 24, the square block 28 will move backward along the inside of the fixed block 24.

[0050] A hinge block 29 is fixedly mounted on the top of the square block 28 , and a movable rod 30 is hinged inside the hinge block 29 .

[0051] When the square block 28 moves backward, the square block 28 drives the movable rod 30 to move through the hinge block 29.

[0052] Among them, the other end of the movable rod 30 is internally movably sleeved with a movable block 31, and the top of the movable block 31 is fixedly installed with an extrusion plate 32. The left and right sides of the extrusion plate 32 are movably connected to the limiting blocks 33, and the right side of the limiting block 33 is fixedly connected to the left side of the base 22.

[0053] When the hinge block 29 drives the movable rod 30 to move, the other end of the movable rod 30 will squeeze and push the movable block 31, so that the movable block 31 drives the extrusion plate 32 to move. Due to the limitation of the limit block 33, the extrusion plate 32 will move upward.

[0054] Among them, the extrusion plate 32 is internally movably connected to the extrusion shaft 34, the outer surface of the extrusion shaft 34 is internally movably connected to the arc groove 23, the other end of the extrusion shaft 34 is fixedly installed with a material trough 35, the outer surface of the material trough 35 is internally movably connected to the base 22, and the left and right sides of the material trough 35 are fixedly installed with fixed shafts 36, and the outer surface of the fixed shaft 36 is internally movably sleeved with the left and right sides of the base 22.

[0055] When the extrusion plate 32 moves upward, the inside of the extrusion plate 32 will squeeze and push the extrusion shaft 34 so that the extrusion shaft 34 moves along the inside of the arc groove 23. At this time, the material trough 35 will rotate around the fixed shaft 36 as the axis driven by the extrusion shaft 34.

[0056] An arc block 37 is fixedly mounted on the back of the base 22 , and a water spray pipe 38 is fixedly sleeved inside the arc block 37 .

[0057] Due to the design of the water spray pipe 38 , water can be flushed into the interior of the trough 35 , thereby facilitating the cleaning of the trough 35 .

[0058] The working principle and use process of this utility model:

[0059] First, the operator starts the drive motor 18, then the rotating shaft 19 will drive the gear 7 to rotate. Since the outer surface of the gear 7 is meshed with the outer surface of the toothed plate 8, when the gear 7 rotates, it will drive the toothed plate 8 to move, and then the toothed plate 8 will drive the long rod 9 to move. At this time, the three short rods 10 will move under the drive of the long rod 9. Due to the design of the three limiting grooves 6, the movement of the three short rods 10 will be limited so that it can only move left and right. At this time, the three short rods 10 will move to the right along the inside of the three limiting grooves 6 under the drive of the long rod 9. At this time, the three extrusion blocks 11 will move to the right along the inside of the three short slots 3 under the drive of the three short rods 10. At this time, the outer surfaces of the three extrusion blocks 11 will squeeze and push the inside of the three moving plates 12 during the right movement, so that the three moving plates 12 drive The three first partitions 13 move to the right along the outer surface of the three second partitions 14. At this time, the three moving plates 12 will shorten the distance between them and the three circular plates 15 during the rightward movement, thereby reducing the volume between the moving plates 12 and the circular plates 15, thereby realizing the function of adjusting the amount of feed according to the size of the pigs. The operator then pours feed into the inside of the feeding hopper 5, and then the feed will fall into the inside of the barrel 1 through the three feeding ports 2. Due to the design of the three first partitions 13 and the three second partitions 14, the feed inside the barrel 1 can be evenly divided into four equal parts. At this time, the operator starts the first power motor 20, and the rotating shaft 21 will drive the round rod 16 to rotate as a whole. At this time, the feed inside the barrel 1 will fall into the inside of the trough 35 through the three discharge ports 4, so that the pigs can be fed.

[0060] When the pigs are fed, the operator starts the second power motor 25. At this time, the short shaft 26 will drive the screw 27 to rotate. Since the outer surface of the screw 27 is threaded with the inner thread of the square block 28, when the screw 27 rotates, it will drive the square block 28 to move. Since the outer surface of the square block 28 is movably connected with the inner part of the fixed block 24, the square block 28 will move backward along the inner part of the fixed block 24. At this time, the hinged block 29 will move backward under the drive of the square block 28, and then the movable rod 30 will move under the drive of the hinged block 29. At the same time, the other end of the movable rod 30 will squeeze and push the movable block 31, so that the movable block 31 drives the extrusion plate 32 to move. Due to the design of the two limit blocks 33, the movement of the extrusion plate 32 will be limited, so that the extrusion plate 32 can only move upward. At this time, the extrusion plate 32 will move upward under the drive of the movable block 31. When the extrusion plate 32 moves upward, its interior will squeeze and push the outer surface of the extrusion shaft 34. Due to the design of the arc groove 23, the movement of the extrusion shaft 34 will be limited. At this time, the extrusion shaft 34 will move along the inside of the arc groove 23. At this time, the trough 35 will rotate with the two fixed shafts 36 as the axis under the drive of the extrusion shaft 34. Then the operator flushes water into the inside of the trough 35 through the water pipe 38, thereby realizing the function of facilitating the cleaning of the trough 35.
