Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to a primary cleaning sieve for feed production. Background Art

[0002] Feed is the general term for the food of all animals raised. More narrowly, generally, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed raw materials have different types, including soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils and fats, meat and bone meal, grains, and feed additives. Feeds prepared with different raw materials have different nutrients, and appropriate feeds need to be selected according to the types of animals raised. Before feed production, it is necessary to preliminarily screen the raw materials for preparing feed, and it is necessary to screen out the straws, soils, stones, and rope ends carried in the feed raw materials, which is beneficial to ensuring good feed quality;

[0003] After retrieval, a Chinese patent with the publication number of CN216800522U discloses a primary cleaning sieve for feed production, which solves the problem that current feed screening and processing usually use air blowing to screen impurities, resulting in large impurities being difficult to screen out and poor quality of the produced feed. It includes a housing, and a first motor is connected to the upper part of one side of the housing; in this utility model, the rotating rod drives the auger to rotate, the auger drives the feed to move to one side, the feed falls onto the upper end of the conveyor belt through the rolling sieve, the second motor drives the conveyor belt to convey the feed into the second collection box, and the large impurities move to one side of the rolling sieve through the auger and move out through the discharge port into the first collection box, which can evenly screen the feed and large impurities, making the processed feed of better quality; the first motor drives the rolling sieve to rotate, and the electric telescopic rod drives the brush to move downward to brush the rolling sieve to prevent the sieve holes of the rolling sieve from being blocked.

[0004] In this patent, the feed raw materials carry impurities such as straws and rope ends. When the rope ends are long, it is easy to have the problem that the rope ends are wound around the stirring shaft and cannot fall off. When both ends of the straws and rope ends penetrate into the sieve holes along the rotation direction of the rolling sieve, the straws and rope ends in the sieve holes cannot be quickly pulled out only by the brush, and the straws and rope ends will still block the sieve holes, which is not conducive to improving the convenience of the equipment.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] The following is a further description of the present utility model in combination with the attached Figures 1-4 drawings.

[0026] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a primary cleaner for feed production.

[0027] In a specific technical solution, it includes a housing 1 and a screening and cutting assembly 2;

[0028] As Figures 1-3 shown, the screening and cutting assembly 2 is installed inside the housing 1. The screening and cutting assembly 2 is used to screen the feed while cutting the straw and rope ends. The screening and cutting assembly 2 includes a first motor 201 fixedly installed outside the housing 1, a support frame 202 penetrating through the side wall of the housing 1, and a drum 203 located inside the housing 1. The first motor 201 can drive the support frame 202 to rotate. The support frame 202 can support and fix the drum 203. The rotation of the drum 203 can turn over the feed. One end of the support frame 202 is fixedly installed on the output shaft of the first motor 201 and the other end is fixedly connected to the side wall of the drum 203. A second motor 204 is fixedly installed on the side wall of the support frame 202 at the central axis position inside the drum 203. The second motor 204 can drive the cutting shaft 205 to rotate. The cutting shaft 205 fixedly connected to the output shaft of the second motor 204 is installed inside the drum 203. The cutting shaft 205 can cut the rope ends while turning over the feed. Sieve holes 3 are opened on the side wall of the drum 203. The sieve holes 3 can screen out impurities.

[0029] When the feed enters the drum 203, looking from the first motor 201 towards the drum 203, by starting the first motor 201 to drive the support frame 202 to rotate counterclockwise, the support frame 202 drives the drum 203 to rotate counterclockwise. At the same time, start the second motor 204 to drive the cutting shaft 205 to rotate clockwise. The rotation speed of the cutting shaft 205 is greater than that of the drum 203. The drum 203 turns over the feed counterclockwise, and then the cutting shaft 205 turns over and disperses the feed clockwise, which can make the feed looser and is conducive to the impurities mixed in the feed falling off. The impurities can fall out of the drum 203 from the sieve holes 3, and the impurities in the feed can be screened out. Moreover, when the cutting shaft 205 rotates, the edge of the blade rotates along the inner wall of the drum 203. The blade on the cutting shaft 205 can cut off the straw and rope ends passing through the sieve holes 3, which is conducive to the straw falling off and can prevent the longer rope ends from winding around the central axis of the cutting shaft 205.

[0030] As Figures 1-4As shown in the figure, a dragging component 4 is installed below the outer shell 1. The dragging component 4 is used to pull out the straw and rope ends in the sieve holes 3. The dragging component 4 includes a waste hopper 401 fixedly installed at the bottom of the outer shell 1, and a baffle 402, a clamping plate one 403, and a clamping plate two 404 located at the bottom of the roller 203. The waste hopper 401 facilitates the leakage of impurities. The baffle 402 can prevent impurities from entering the discharge hopper 8. The clamping plate one 403 and the clamping plate two 404 can clamp the straw and rope ends that leak out of the sieve holes 3 and have not fallen, which is convenient for pulling out the straw and rope ends. The baffle 402 is fixedly installed at the top of the baffle 402. The two ends of the clamping plate one 403 are respectively fixedly connected to the inner wall of the waste hopper 401 and the side wall of the baffle 402. The clamping plate two 404 is sequentially and staggeredly clamped with the clamping plate one 403. A telescopic rod 405 with a telescopic end fixedly connected to the clamping plate two 404 is fixedly installed on the side wall of the baffle 402. The telescopic rod 405 can drive the clamping plate two 404 to move.

[0031] When the straw and rope ends stuck in the sieve holes 3 do not fall and leak out of the sieve holes, the rotation of the roller 203 drives the rotation of the sieve holes 3. The sieve holes 3 drive the straw and rope ends to rotate counterclockwise. The straw and rope ends are stuck between the plates of the clamping plate one 403. By starting the telescopic rod 405, the telescopic rod 405 drives the clamping plate two 404 to move. The plates in the clamping plate two 404 are arranged in sequence and staggeredly with the plates in the clamping plate one 403. The plates in the clamping plate two 404 move towards the adjacent plates in the clamping plate one 403. The straw and rope ends can be clamped between the plates of the clamping plate one 403 and the clamping plate two 404. The roller 203 drives the sieve holes 3 to rotate, and the sieve holes 3 move away from the clamped straw and rope ends, which can pull the straw and rope ends out of the sieve holes 3. By starting the telescopic rod 405 in the reverse direction, the telescopic rod 405 drives the clamping plate two 404 to move in the reverse direction, and the straw and rope ends can fall into the waste hopper 401.

[0032] As Figure 1 and Figure 3 shown in the figure, a limiting plate 5 fixedly connected to the inner side wall of the outer shell 1 is installed at one end of the roller 203. The limiting plate 5 can limit one end of the roller 203 away from the support frame 202, increasing the stability of the roller 203. A feed inlet 6 is opened on the side wall of the limiting plate 5. The feed inlet 6 can facilitate the feeding of feed into the roller 203.

[0033] As Figures 1-2 and Figure 3 shown in the figure, a feed hopper 7 fixedly connected to the feed inlet 6 is fixedly installed on the side wall of the limiting plate 5. The feed hopper 7 is fixedly penetrated through the top wall of the outer shell 1. Pouring the feed into the feed hopper 7, the feed in the feed hopper 7 can enter the roller 203 through the feed inlet 6.

[0034] As Figures 1-2As shown, a discharge hopper 8 is fixedly installed at the bottom of the outer shell 1. The sieved feed is pushed by the cutting shaft 205 to the port of the roller 203 near the support frame 202, and the sieved feed falls out from the port of the roller 203 and enters the discharge hopper 8.

[0035] As Figures 1-2 shown, legs 9 are welded to the outside of the outer shell 1, and the legs 9 can support the stability of the outer shell 1.
