Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to a vibrating sieve powder machine for organic fertilizer. Background Technique

[0002] Organic fertilizers mainly come from plants and animals. They are carbon-containing materials applied to the soil to provide plant nutrition as their main function. They can promote the reproduction of microorganisms, improve the physical and chemical properties and biological activities of the soil, and are the main nutrients for the production of green food. Organic fertilizers are usually mixed from a variety of raw materials. Before mixing, these raw materials first need to remove miscellaneous materials such as sand and gravel inside the raw materials through screening. Most of the existing vibrating sieves pour the mixed materials at one end of the vibrating sieve plate, and then use the vibrating sieve to disperse the mixed materials, and then carry out screening. It is necessary for the mixed materials to move from one end of the vibrating sieve plate to the other end, resulting in low vibrating sieve efficiency, and a large amount of mixed materials are piled up at one end of the vibrating sieve plate and are not suitable for screening.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a vibrating sieving machine for organic fertilizers, including an outer shell 1, a vibration sieve plate 2 and a hopper 3 are arranged inside the outer shell 1, and a discharging mechanism 4 is arranged on the outer wall of the hopper 3;

[0022] The feeding mechanism 4 includes a limit frame 401 and a rack 405. The limit frame 401 is slidably sleeved on the hopper 3. The limit frame 401 is fixedly installed on the inner wall of the housing 1. A motor 402 is fixedly installed on the top of the limit frame 401. The output end of the motor 402 is fixedly installed with a reciprocating lead screw 403. A connecting block 404 is threadedly sleeved on the outer wall of the reciprocating lead screw 403. The connecting block 404 is fixedly installed on the top of the hopper 3. The rack 405 is fixedly installed on the inner wall of the front surface of the housing 1. The rack 405 meshes with a gear 408. A threaded rod 407 is fixedly installed on the inner wall of the gear 408. An L-shaped plate 406 is rotatably sleeved on the outer wall of the threaded rod 407 through a bearing. The L-shaped plate 406 is fixedly installed on the top of the hopper 3. An internally threaded pipe 409 is threadedly sleeved on the outer wall of the threaded rod 407. A plug 4010 is fixedly installed at the bottom end of the internally threaded pipe 409. The plug 4010 is slidably arranged in the hopper 3, and the front and back surfaces of the plug 4010 are respectively in contact with the inner wall of the front surface and the inner wall of the back surface of the hopper 3. The upper half of the plug 4010 is larger than its lower half. The limit frame 401 is provided to limit the hopper 3, so that the hopper 3 cannot rotate relative to the limit frame 401. The motor 402 drives the reciprocating lead screw 403 to rotate, so that the connecting block 404 reciprocates along the reciprocating lead screw 403, and then drives the hopper 3 to reciprocate, so that the hopper 3 discharges the mixed material at different positions on the vibrating sieve plate 2. During the movement of the hopper 3, the gear 408 is driven to move, and then the gear 408 is pushed by the rack 405 to rotate. The rotation of the rack 405 drives the threaded rod 407 to rotate, and then the internally threaded pipe 409 moves up or down, so that the internally threaded pipe 409 drives the plug 4010 to move down or down. Using the characteristic that the plug 4010 is larger at the top and smaller at the bottom, when the hopper 3 approaches the right end of the vibrating sieve plate 2, the plug 4010 gradually blocks the bottom opening of the hopper 3, reducing the amount discharged at the right end of the vibrating sieve plate 2 and preventing the mixed material from being discharged without being screened in time;

[0023] On the left inner wall of the housing 1, a fixing plate 10 is fixedly installed. On the top of the fixing plate 10, an elastic support member 12 is fixedly installed. The top end of the elastic support member 12 is fixedly connected to the bottom of the vibrating sieve plate 2. On the top of the fixing plate 10, a vibrator 11 is fixedly installed. The output end of the vibrator 11 is fixedly connected to the bottom of the vibrating sieve plate 2. The elastic support member 12 is provided to connect the fixing plate 10 and the vibrating sieve plate 2, enabling the vibrating sieve plate 2 to vibrate within a certain range. The vibrator 11 is provided to vibrate the vibrating sieve plate 2, thereby realizing the vibration screening of the mixture on the vibrating sieve plate 2. The elastic support member 12 includes a fixed cylinder 1201. The fixed cylinder 1201 is fixedly installed on the top of the fixing plate 10. On the bottom inner wall of the fixed cylinder 1201, a spring 1202 is fixedly installed. The top end of the spring 1202 is fixedly installed with a sliding plate 1203. The sliding plate 1203 is slidably arranged within the fixed cylinder 1201. On the top of the sliding plate 1203, a connecting rod 1204 is fixedly installed. The top end of the connecting rod 1204 is fixedly connected to the bottom of the vibrating sieve plate 2. By connecting the fixed cylinder 1201 and the sliding plate 1203 through the spring 1202, the sliding plate 1203 can slide up and down, and thus the connecting rod 1204 can slide up and down, enabling the vibrating sieve plate 2 to be vibrated by the vibrator 11;

[0024] On the right outer wall of the housing 1, a material receiving tray 5 is fixedly installed. On the left outer wall of the housing 1, a discharge port 6 is provided. The discharge port 6 is located below the fixing plate 10 and is used to separately store and take out the screened mixed materials;

[0025] On the left outer wall of the hopper 3, a connecting seat 7 is fixedly installed. The inner wall of the connecting seat 7 is rotatably connected to a rotating shaft 8 through a bearing. On the outer wall of the rotating shaft 8, a pushing rod 9 is fixedly installed. By moving the hopper 3, the connecting seat 7 is driven to move, and then the rotating shaft 8 is driven to move, so that the pushing rod 9 on the rotating shaft 8 pushes the mixture on the vibrating sieve plate 2, spreading out the mixture on the vibrating sieve plate 2 and improving the vibration screening effect of the vibrating sieve plate 2 on the mixture. A plurality of pushing rods 9 are provided and are circumferentially and arrayedly distributed on the rotating shaft 8 to improve the pushing efficiency. The gap between the pushing rod 9 and the upper surface of the vibrating sieve plate 2 is greater than the maximum vibration stroke of the vibrator 11 to prevent the vibrating sieve plate 2 from colliding with the pushing rod 9 during the up and down vibration.

[0026] Working principle: When in use, start the motor 402 to drive the reciprocating lead screw 403 to rotate, and then add the mixture into the hopper 3. The rotation of the reciprocating lead screw 403 causes the connecting block 404 to reciprocate along the reciprocating lead screw 403, thereby driving the hopper 3 to reciprocate, so that the hopper 3 discharges the mixture at different positions on the vibrating sieve plate 2. During the movement of the hopper 3, the gear 408 is driven to move, and then the gear 408 is pushed by the rack 405 to rotate. The rotation of the rack 405 drives the threaded rod 407 to rotate, thereby causing the internal threaded tube 409 to move up or down, so that the internal threaded tube 409 drives the plug 4010 to move down or up. Utilizing the characteristic that the plug 4010 is larger at the top and smaller at the bottom, when the hopper 3 approaches the right end of the vibrating sieve plate 2, the plug 4010 gradually blocks the bottom opening of the hopper 3, reducing the amount discharged at the right end of the vibrating sieve plate 2, and avoiding the mixture being discharged without being screened in time.
