Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, and in particular to an alfalfa pellet screening device. Background Technology

[0002] The alfalfa pellet screening device effectively grades and removes impurities from alfalfa pellets, ensuring consistent product quality and high purity, thereby improving feed safety, nutritional value, and market value. This is of great significance for improving the overall efficiency and sustainable development of animal husbandry.

[0003] Most alfalfa pellet screening devices nowadays use linear vibration mechanisms. Linear vibration applies a unidirectional force to the alfalfa pellets. However, a unidirectional force can only act in a fixed direction. Friction and adhesion between pellets can exist in all directions. As a result, when pellets agglomerate, the interaction forces between them are strong, and it is difficult for a unidirectional force to act simultaneously from all directions, making it difficult to loosen the agglomerated pellets.

[0004] Agglomerated particles are difficult to pass through the screen mesh, resulting in uneven screening, which affects the quality and consistency of the final product and also reduces the screening efficiency of the equipment. Utility Model Content

[0007] The two rotating shafts and the fixed rod are equipped with a power mechanism and a buffer mechanism on the opposite side of the two fixed plates. The multi-directional force can better overcome the friction and adhesion between particles, making it easier to break up agglomerated particles and thus reducing the agglomeration of materials.

[0008] In a preferred embodiment, the power mechanism includes two motors, the output shafts of the two motors are fixedly mounted to the two rotating shafts, and a positioning plate is bolted to the top of the motor.

[0009] In a preferred embodiment, the buffer mechanism includes two bushings, which are fixedly connected to the outer surfaces of two fixed rods near their ends. Multiple fixed rods are movably embedded in the inner surfaces of the two bushings, with a clearance fit between the multiple fixed rods and the two bushings. Two springs are movably sleeved on the outer surfaces of each of the multiple fixed rods. Two limiting plates are fixedly connected to the outer surfaces of the two fixed plates on their back sides near the two arc-shaped sliding holes, and the limiting plates can fix the springs.

[0010] In a preferred embodiment, a plurality of filter plates are fixedly installed on the inner surface of the housing, and a guide plate is fixedly connected to the top of each of the plurality of filter plates. The guide plates can guide the product on the filter plates.

[0013] In a preferred embodiment, the filter pores of the plurality of filter plates are gradually reduced in size, which can achieve graded screening and ensure screening efficiency.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention utilizes circular arc vibration to replace horizontal and vertical vibration, causing particles to be continuously subjected to forces in different directions under the action of circular arc motion. These forces include horizontal, vertical, and tangential forces. The multi-directional forces can better overcome the friction and adhesion between particles, making it easier to break up agglomerated particles, thereby reducing material agglomeration and improving screening efficiency and uniformity.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an alfalfa pellet screening device, comprising: an outer shell 1 and two fixing plates 14, two rotating shafts 16 and fixing rods 4 are movably embedded in the inner surfaces of the two fixing plates 14, and arc-shaped sliding holes 11 are opened on the side of the two fixing plates 14 near the two fixing rods 4. Circular plates 15 and 2 circular plates 5 are fixedly installed on the opposite side of the two rotating shafts 16 and the fixing rods 4 near the two fixing plates 14. Multiple protrusions 17 are fixedly connected to the outer surface of circular plate 15, and protrusions 26 are fixedly connected to the outer surface of circular plate 25. A rotating shaft 3 2 is movably embedded in the side of the outer shell 1 away from the two rotating shafts 16, and two base plates 3 are fixedly sleeved on the outer surfaces of the two rotating shafts 3 2.

[0025] Two rotating shafts 16 and fixed rod 4 are equipped with a power mechanism and a buffer mechanism on the opposite side of the two fixed plates 14. The multi-directional force can better overcome the friction and adhesion between particles, making it easier to break up agglomerated particles, thereby reducing the agglomeration of materials and improving screening efficiency and uniformity.

[0026] like Figure 1-5 As shown, the power mechanism includes two motors 13. The output shafts of the two motors 13 are fixedly installed with two rotating shafts 16. A positioning plate 12 is bolted to the top of the motor 13. The positioning plate 12 is fixedly installed on the outer surface of the two fixed plates 14. The motor 13 can provide power for the rotation of the rotating shaft 16, so that the rotating shaft 16 drives the circular plate 15 to rotate.

[0027] like Figure 1-5 As shown, the buffer mechanism includes two bushings 7, which are fixedly connected to the outer surfaces of two fixed rods 1 4 near both ends. Multiple fixed rods 2 8 are movably embedded in the inner surfaces of the two bushings 7, and the multiple fixed rods 2 8 are clearance-fitted with the two bushings 7. Two springs 9 are movably sleeved on the outer surfaces of the multiple fixed rods 2 8. Two limiting plates 10 are fixedly connected to the outer surfaces of the two fixed plates 14 near the two arc-shaped sliding holes 11 on both sides. The limiting plates 10 can fix the springs 9 and provide a good working environment for the springs 9.

[0028] like Figure 1-5 As shown, multiple filter plates 18 are fixedly installed on the inner surface of the outer casing 1. Each filter plate 18 is fixedly connected to a guide plate 20. The multiple guide plates 20 can guide the product on the filter plates 18. A guide plate 19 is fixedly connected to the side of the outer casing 1 near the multiple guide plates 20. The guide plate 20 can guide the product so that the product is led out of the outer casing 1 from the guide plate 19.

[0029] like Figure 1-5 As shown, two fixed rods 4 are movably embedded in the inner surface of two arc-shaped sliding holes 11, and two fixed rods 4 are fixedly embedded in the inner surface of the outer shell 1. The center of the two arc-shaped sliding holes 11 is concentric with the center of the rotating shaft 2. The rotating shaft 2 can provide the center for the arc vibration of the outer shell 1 and create conditions for vibration in the arc direction.

[0030] like Figure 1-5 As shown, multiple fixing rods 8 are fixedly connected to the opposite outer surfaces of multiple limiting plates 10, and multiple springs 9 are fixedly connected to the outer surfaces of two bushings 7. The springs 9 can buffer the bushings 7, thereby buffering the fixing rods 4.

[0031] like Figure 1-5As shown, the filter holes of the multiple filter plates 18 are gradually reduced in size, which can achieve graded screening and improve screening efficiency.

[0032] Working principle: This equipment is an alfalfa pellet screening device. When in use, the product is introduced into the first filter plate 18 in the outer shell 1. Then, the motor 13 on the surface of the positioning plate 12 is started. The motor 13 drives the rotating shaft 16 to rotate through the output shaft. The rotating shaft 16 drives the protrusion 17 on the circular plate 15 to rotate. The protrusion 17 will continuously hit the protrusion 6, causing the protrusion 6 to drive the fixed rod 4 to move up and down through the circular plate 25. In turn, the fixed rod 4 can drive the outer shell 1 and the bushing 7 to make an arc motion with the rotating shaft 2 on the base plate 3 as the center. This causes the filter plate 18 to vibrate synchronously in an arc motion to sort the product. Then, the sorted product gradually flows to the guide plate 19 due to the restriction of the guide plate 20, and then is led out of the outer shell 1.

[0033] When the bushing 7 moves outside the fixed rod 2 8 and inside the arc-shaped sliding hole 11 on the fixed plate 14, it will squeeze or stretch the spring 9 on the limiting plate 10, causing the spring 9 to deform and obtain elastic potential energy, thereby enabling the spring 9 to buffer the fixed rod 1 4.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
