[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figure 1-5As shown, a feed dispensing adjustment device for pregnant cows includes a dispensing box 1; a conveyor belt 11 is installed at the bottom of the dispensing box 1; a feeding port 12 is installed on the side wall of the dispensing box 1; a rotating rod 13 is rotatably connected to the middle of the feeding port 12; a limiting member 14 is fixedly connected to the end of the rotating rod 13; an internal toothed belt 15 is installed on the inner wall of the limiting member 14, and the other end of the internal toothed belt 15 is installed on the output shaft of the conveyor belt 11; multiple sets of connecting members 16 are fixedly connected to the middle of the rotating rod 13, and the multiple sets of connecting members 16 are... 6 is located inside the feeding port 12; two sets of discharge plates 17 are fixed to the outer wall of the connector 16, and the middle of the discharge plate 17 is arc-shaped; during operation, the feeding box 1 can be installed on a small vehicle, and an appropriate amount of feed can be transferred into the feeding box 1, so that the feeding box 1 can stir and transport the feed inside until it is discharged from the feeding port 12 and falls onto the conveyor belt 11, and is then transferred to the pasture feeding area for the cattle to consume. An internal toothed belt 15 is installed on the shaft. During operation, the conveyor belt 11 drives the rotating rod 13 to move, causing the rotating rod 13, which rotates on the inner wall of the feeding port 12, to cause multiple sets of discharge plates 17 to rotate synchronously. The staggered discharge plates 17 can intermittently contact the nearby feed, and due to their concave shape, they can pull the nearby feed to the feeding port 12 for discharge. When the feeding speed needs to be adjusted, the rotation speed of the conveyor belt 11 can be adjusted. At the same time, the rotation speed of the multiple sets of discharge plates 17 can also be changed accordingly, thus adjusting the feeding speed. This step, by setting the internal toothed belt 15 on the conveyor belt 11, can improve the synchronization of the operation of the feeding port 12 and the conveyor belt 11, and reduce the problem that the original feeding port 12 was manually adjustable, making it difficult to flexibly change the feeding amount for different herds. In addition, the multiple sets of staggered connectors 16 can improve the uniformity of feed distribution on the conveyor belt 11.

[0026] like Figure 1-5As shown, two sets of collars 2 are fixedly connected to the middle of the rotating rod 13; a sliding rod 21 is slidably connected to the middle of the collar 2, and the sliding rod 21 passes through the middle of the rotating rod 13; a spring 22 is fixedly connected to the inner wall of the sliding rod 21; a sliding shaft 23 is fixedly connected to the end of the spring 22, and the sliding shaft 23 is slidably disposed on the inner wall of the sliding rod 21; a counterweight 24 is fixedly connected to the end of the sliding shaft 23, and the counterweight 24 is disposed near the inner wall of the feeding port 12; during operation, because two sets of collars 2 are disposed in the middle of the rotating rod 13, the counterweight 24, under the action of gravity, can be positioned such that one end is close to the rotating rod 13 and the other end is away from the rotating rod 13, and then... As the rotating rod 13 continues to rotate, the center of gravity of the two sets of counterweights 24 gradually changes, causing the top counterweight 24 to move to the bottom. With the help of the sliding rod 21, it can slide up and down on the rotating rod 13. During the movement, the length of the specified spring 22 can be changed. This step, together with the two sets of up and down moving counterweights 24, can push open and clear the material accumulated at the edge of the feeding port 12, reducing the problem of material sticking to the inner wall of the feeding port 12 and causing blockage due to prolonged lack of clearing. With the help of the spring 22, the counterweights 24 can move slightly during the movement, reducing the residue adhesion on the surface of the two sets of counterweights 24 after frequent use.

[0027] like Figure 1-5 As shown, a protective cover 3 is fixedly connected to the top of the discharge plate 17; an elastic rope 31 is fixedly connected to the inner wall of the protective cover 3; and a counterweight ball 32 is fixedly connected to the middle of the elastic rope 31. During operation, by setting the protective cover 3 on the outer wall of the discharge plate 17, the counterweight ball 32 inside the protective cover 3 can strike the designated outer wall of the discharge plate 17 in sequence under the action of rotational inertia during the rotation of the discharge plate 17. Then, it is pulled back by the elastic rope 31. This process is repeated, and the discharge plate 17 generates vibration. This step can improve the cleanliness of the surface of the discharge plate 17 under the action of the vibration generated by the impact. Moreover, under the action of unfolding the protective cover 3, the direct contact between the feed residue in the conveyor belt 11 and the feeding port 12 and the elastic rope 31 can be reduced, thus reducing the problem of large corrosion caused by the direct contact between the feed residue and the elastic rope 31, thereby playing a protective role.

[0028] like Figure 1-5 As shown, an elastic sheet 4 is fixedly connected to the outer wall of the feeding port 12; a top rod 41 is fixedly connected to the end of the rotating rod 13, and the top rod 41 is positioned close to the elastic sheet 4. During operation, because the elastic sheet 4 is provided on the outer wall of the feeding port 12, when the rotating rod 13 rotates, the two ends of the top rod 41 that extends at its end can sequentially approach the middle position of the elastic sheet 4 and then move away, causing the elastic sheet 4 to vibrate during this process. Under the action of the elastic sheet 4, this step can clean away the impurities accumulated on the inner wall or top wall of the feeding port 12, reducing the accumulation of internal residue and preventing the gradual formation of more material, which can easily cause blockage.

[0029] like Figure 1-5 As shown, two sets of shielding cloths 5 are fixedly connected to the side wall of the feeding port 12; a counterweight rod 51 is fixedly connected to the bottom of the shielding cloth 5; during operation, by setting two sets of shielding cloths 5 on the outer wall of the feeding port 12, and the counterweight rod 51 can straighten the shielding cloths 5, so that when feed is discharged from the feeding port 12, the two sets of shielding cloths 5 can be unfolded and guided. Under the action of the shielding cloths 5, this step can reduce the problem of material deviation when transferred to the conveyor belt 11, which would cause it to fall onto the inner wall of the conveyor belt 11 and make subsequent cleaning troublesome. With the counterweight rod 51, the stability of the shielding cloths 5 during operation can be improved.

[0030] like Figure 1-5 As shown, a scraper 6 is fixedly connected to the side wall of the counterweight 24, and the scraper 6 is in contact with the inner wall of the feeding port 12. During operation, by providing a scraper 6 at the end of the counterweight 24, the scraper 6 can wipe a part of the inner wall of the feeding port 12 when the counterweight 24 is in use. This step, under the action of the scraper 6, can improve the cleanliness of the rotating shaft of the rotating rod 13 and reduce the problem that a lot of residue accumulates at both ends of the rotating rod 13, and that failure to clean it in time will cause greater resistance when rotating later.

[0031] Working principle: By installing the feeding box 1 on a small vehicle and transferring an appropriate amount of feed into the feeding box 1, the feeding box 1 can stir and transport the feed until it is discharged from the feeding port 12 and falls onto the conveyor belt 11, which then transfers it to the pasture feeding area for cattle to consume. An internal toothed belt 15 is installed on the rotating shaft of the conveyor belt 11. During operation, the conveyor belt 11 drives the rotating rod 13 to move, causing multiple sets of discharge plates 17 to rotate synchronously. The staggered discharge plates... 17 can intermittently contact the nearby feed, and due to its concave shape, it can pull the nearby feed to the feeding port 12 for discharge. When the feeding speed needs to be adjusted, the rotation speed of the conveyor belt 11 can be adjusted. At the same time, the rotation speed of the multiple sets of discharge plates 17 can also be changed accordingly, thus adjusting the feeding speed of the feed. By setting two sets of collars 2 in the middle of the rotating rod 13, during the rotation of the rotating rod 13, the counterweight bar 24 can be positioned with one end close to the rotating rod 13 and the other end away from the rotating rod 13 under the action of gravity. As rotation continues, the center of gravity of the two sets of counterweights 24 gradually changes, causing the top counterweight 24 to move to the bottom. This allows it to slide up and down on the rotating rod 13 via the sliding rod 21. During the movement, the length of the designated spring 22 can be changed. Because a protective cover 3 is provided on the outer wall of the discharge plate 17, during rotation, the counterweight balls 32 inside the protective cover 3 strike the designated outer wall of the discharge plate 17 sequentially due to rotational inertia. They are then pulled back by the elastic rope 31, and this process is repeated, causing the discharge plate 17 to vibrate. An elastic sheet 4 is provided on the outer wall of the feeding port 12. When the rotating rod 13 rotates, the two ends of the extended top rod 41 at its end can approach the middle position of the elastic sheet 4 in sequence and then move away, causing the elastic sheet 4 to shake during this process. Two sets of shielding cloths 5 are provided on the outer wall of the feeding port 12. The counterweight rod 51 can straighten the shielding cloths 5, so that when feed is discharged from the feeding port 12, the two sets of shielding cloths 5 can be guided. A scraper 6 is provided at the end of the counterweight bar 24, so that when the counterweight bar 24 is in use, the scraper 6 can wipe a part of the inner wall of the feeding port 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
