Description

Technical Field

[0001] The utility model relates to a feed granulator, in particular to a feed granulator with a particle screening function for feed production, belonging to the technical field of feed production. Background Art

[0002] In the prior art, as disclosed in the utility model with the application number 202121837090.1, a feed granulator with a particle screening function for feed production is disclosed. In order to solve the problems that when the feed granulator is in use, the sizes of the produced particles are inconsistent, and powdery materials are likely to appear, and the mixture will affect the quality of the feed, and at the same time, the powdery materials are not convenient for users to use, the rotating box is driven to rotate by a transmission device, and the processed granular feed falls into the inside of the rotating box through the discharge port, and then the feed can be driven to rotate by the rotating box. During this process, it passes through the material distribution plate for filtering and screening, so that feeds of different sizes fall through different discharge hoppers. The operation is simple, which is convenient for users to screen the produced granular feed, so as to make the discharge uniform, ensure the quality of the product, and be more convenient to use.

[0003] There are still deficiencies in the similar applications as above:

[0004] Since the feed is mostly in a long strip shape after forming, the mesh holes of the screening plate are mostly circular, and the states of the feed in the rotating box are different. The screening method using the material distribution plate cannot ensure uniform screening, and the screening rate is slow, which is likely to cause blockage of the mesh holes and affect the use efficiency;

[0005] Therefore, a feed granulator with a particle screening function for feed production is designed to optimize the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the technical solutions of the utility model clearer and more definite for those skilled in the art, the following further describes the utility model in detail with reference to the embodiments and the accompanying drawings, but the embodiments of the utility model are not limited thereto.

[0024] Such as Figures 1 - 4As shown in the figure, this embodiment provides a feed granulator with a particle screening function for feed production, including a bottom plate 1, a speed reducer 2 installed on the top of the bottom plate 1, a driving motor 3 located on the top of the bottom plate 1 and connected to the driving shaft on the speed reducer 2, a processing box 4 installed on the top of the speed reducer 2 and connected to the output shaft of the speed reducer 2, a feed hopper 5 installed on the top of the processing box 4, and a discharge hopper 6 installed on the outside of the processing box 4. One side of the top of the speed reducer 2 is fixed with an air box 7. Inside the air box 7, a bracket 8 is vertically installed. On the bracket 8, a first shaft 9 is horizontally rotatably installed. One end of the first shaft 9 is installed with a fan blade 11. A first pulley assembly 10 is provided between the first shaft 9 and the output shaft of the driving motor 3. One end of the air box 7 close to the discharge hopper 6 is installed with an exhaust pipe 12. The end of the exhaust pipe 12 away from the air box 7 is horizontally provided with an exhaust hood 13, and the exhaust hood 13 is located below the discharge hopper 6. A collection box 14 is provided at a position on the top of the bottom plate 1 away from the driving motor 3 and below the discharge hopper 6. A partition plate 15 is vertically installed at the inner bottom of the collection box 14. A shaking mechanism 17 is provided below the feed hopper 5.

[0025] Overall working principle: When in use, the driving motor 3 drives the speed reducer 2 to rotate, and the speed reducer 2 drives the processing box 4 to work, processes the materials entering from the feed hopper 5 into particles, and discharges them from the discharge hopper 6. At the same time, during the rotation of the driving motor 3, the first shaft 9 is driven to rotate by the first pulley assembly 10, and the fan blade 11 at the end of the first shaft 9 will rotate, draw air from the outside and discharge it horizontally from the exhaust hood 13. The materials falling from the discharge hopper 6 will be affected by the wind force. Different-sized particles are affected by different horizontal forces exerted by the wind. Therefore, the feed will fall to different positions. The inside of the collection box 14 is divided by the partition plate 15, and then the materials with different particle sizes are collected and stored.

[0026] In this embodiment, a dust filter screen 16 is vertically installed at the air inlet at the end of the air box 7 away from the exhaust pipe 12.

[0027] Local working principle: When the outside air enters the inside of the air box 7, it will first be filtered by the dust filter screen 16 to ensure the cleanliness of the surface of the fan blade 11 and ensure the air supply effect.

[0028] In this embodiment, there are two groups of partition plates 15, and the partition plates 15 are slidably inserted into the collection box 14. Discharge ports are evenly opened on the outside of the partition plates 15.

[0029] Local working principle: During the use process, the partition plates 15 are inserted and installed, which is more convenient for installation and use, and the number of partition plates 15 can be controlled according to the screening requirements, with higher practicability.

[0030] In this embodiment, the jitter mechanism 17 includes a telescopic tube 18, a spring 19, a second shaft 20, a cam 21, and a second pulley assembly 22. The telescopic tube 18 is installed between the bottom end of the feed hopper 5 and the top of the processing box 4. Springs 19 are evenly arranged between the outer side of the bottom of the feed hopper 5 and the processing box 4. A second shaft 20 is rotatably installed on one side of the processing box 4. A cam 21 is provided at the end of the second shaft 20 and below the feed hopper 5. A second pulley assembly 22 is provided between the end of the second shaft 20 and the first shaft 9.

[0031] Local working principle: When the first shaft 9 rotates, the second shaft 20 will be driven to rotate through the second pulley assembly 22. The cam 21 on the second shaft 20 will control the continuous jitter of the feed hopper 5 to prevent blockage inside the feed hopper 5.

[0032] In this embodiment, a protective shell is provided on the top of the air box 7. The second shaft 20, the cam 21, and the second pulley assembly 22 are all located inside the protective shell.

[0033] Local working principle: The use of the protective shell can ensure the stable operation of the jitter mechanism 17 and has a good protective effect.

[0034] In this embodiment, the top of the cam 21 is arc-shaped, and a wear-resistant coating is provided on the outer side of the arc.

[0035] Local working principle: The arc-shaped surface of the cam 21 and the setting of the wear-resistant coating can reduce the wear of the cam 21 and extend its service life.

[0036] In this embodiment, sliding rods 23 are evenly and vertically installed on the outer side of the bottom of the feed hopper 5. A limiting plate 24 is fixed on the outer side of the processing box 4. The sliding rods 23 are slidably connected to the limiting plate 24.

[0037] Local working principle: When the cam 21 controls the jitter of the feed hopper 5, through the limiting effect of the sliding rods 23 and the limiting plate 24, it is ensured that the feed hopper 5 can only jitter up and down, avoiding the spillage of feed raw materials.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent replacements or changes, all belong to the protection scope of the present invention.
