Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-8One embodiment of the present invention is: a quantitative feeding device for pig farming using gear transmission, comprising a feeding rack 1, a feed tray 2 is fixedly installed at the bottom of the feeding rack 1, a storage tank 3 is fixedly penetrated on the surface of the feeding rack 1, and a quantitative device for quantitatively feeding feed is provided on the inner wall of the feed tray 2, the quantitative device comprises a sieve tray 41, the sieve tray 41 is fixedly installed on the inner wall of the feed tray 2, a leakage tray 42 is fixedly installed on the inner wall of the feed tray 2, a gear rod 43 is slidingly penetrated on the surface of the sieve tray 41, a limiting cone 44 is fixedly installed on the end of the gear rod 43 away from the leakage tray 42, a rotating shaft 45 is fixedly installed on the top of the leakage tray 42, a spiral plate 46 is fixedly installed on the circumferential surface of the rotating shaft 45, a thinning ring 47 is fixedly installed on the circumferential surface of the rotating shaft 45, the rotating shaft 45 drives the thinning ring 47 to rotate, and the flipped feed approaches and contacts the surface of the thinning ring 47; Among them, a fixing frame 51 is fixedly installed on the top of the sieve plate 41, a gear 52 is rotatably passed through the surface of the fixing frame 51, a semi-toothed disc 53 is fixedly installed on the circumferential surface of the gear 52, and a fixing cylinder 54 is fixedly installed on the top of the sieve plate 41.

[0019] The rotating shaft 45 is connected to the output end of the motor, and the angle of the thinning ring 47 is set to an inclined angle. The feed is broken up and thinned under the action of the thinning ring 47, so as to prevent the feed that touches the bottom from clumping or sticking under the pressure of the feed above.

[0020] The half toothed disc 53 is engaged with the gear rod 43, and the shape of the limiting cone 44 is set to a cone to facilitate the discharge of feed. The rotating shaft of gear 1 52 is connected to the output end of the motor. The number of gears 1 52 is set to two, and the two gears 1 52 are engaged with each other. The number of half toothed discs 53 is set to two. The rotation of the half toothed disc 53 drives the gear rod 43 to move upward, and then the gear rod 43 moves upward to drive the limiting cone 44 to move.

[0021] When this embodiment is working: the breeder throws the feed into the feed tray 2 through the feed inlet at the top, starts the motor, and the shaft 45 rotates under the action of the motor output end. The rotation of the shaft 45 drives the spiral plate 46 to rotate, and at the same time, the spiral plate 46 rotates to turn over the feed that touches the bottom of the inner wall of the feed tray 2. At this time, the shaft 45 rotates to drive the thinning ring 47 to rotate. At this time, the turned-up feed approaches and contacts the surface of the thinning ring 47.

At the same time, the gear 1 52 rotates under the action of the motor output end. Because the two gears 1 52 are meshed with each other, the rotation of the gear 1 52 drives the other gear 1 52 to rotate. The first gear 52 rotates. Although the rotation frequency of the two gears 52 is the same, the directions of the half gear disc 53 are not consistent. Because the half gear disc 53 is engaged with the gear rod 43, the rotation of gear 1 52 drives the half gear disc 53 to rotate, and the rotation of the half gear disc 53 drives the gear rod 43 to move upward, and then the gear rod 43 moves upward to drive the limiting cone 44 to move. Under the action of the gear rod 43, the limiting cone 44 moves upward to release the restriction on the discharge port of the sieve plate 1 41. At this time, the feed inside the feed plate 2 is discharged through the discharge port, and then the other half gear disc 53 rotates to drive the gear rod 43 to move downward to limit the discharge port. The capacity of each feeding of the equipment is the length of time the gear rod 43 moves downward and stays. At this time, the quantitative feeding of feed is realized, avoiding waste caused by excessive feed feeding and fighting among pigs due to too little feed feeding.

The end of the sliding frame 68 away from the telescopic elastic rod 1 69 is provided with an arc surface 1 that facilitates the cam 67 to contact and squeeze the upward movement. The upward movement of the sliding frame 68 drives the gear 2 610 to rotate. At this time, the rotation of the gear 2 610 drives the rotating rod 2 65 to rotate.

[0024] The inner wall of the feed tray 2 is provided with a fresh-keeping device for drying and sterilizing the feed inside the feed tray 2. The fresh-keeping device includes a drying ring 71, which is rotatably mounted on the inner wall of 23. A connecting plate 72 is fixedly mounted on the surface of the rotating frame 61.

At the same time, the rotating rod 1 62 rotates to drive the contact wheel 64 to rotate. Because the contact wheel 64 is in contact with the surface of the leakage disc 42, the contact wheel 64 revolves and rotates under the action of the leakage disc 42. At this time, the contact wheel 64 rotates to drive the rotating rod 1 62 to rotate. At the same time, the rotating rod 1 62 rotates to drive the rolling drum 63 to rotate. The rolling drum 63 rotates to roll the feed accumulated on the surface of the leakage disc 42 and touching the bottom, so as to prevent the feed from agglomerating on the surface of the leakage disc 42 and then clogging the surface of the leakage disc 42, thereby affecting the discharge efficiency of the leakage disc 42, thereby affecting the discharge efficiency of the equipment.

[0026] When the rotating rod 1 62 rotates under the action of the contact wheel 64, the rotating frame 61 rotates and drives the rotating rod 2 65 to rotate with the rotating shaft 45 as the center of the circle. The rotating rod 2 65 rotates and drives the odor adsorption plate 66 to rotate. The odor adsorption plate 66 moves to absorb the odor of the feed inside the feed tray 2, thereby improving the air quality of the breeding environment. At the same time, the rotating rod 1 62 rotates and drives the cam 67 to rotate. The cam 67 rotates to contact and squeeze the sliding frame 68 to move upward.
