[0010] Among them, the rectangular frame is connected to the servo motor through a semi-gear and rack meshing mechanism, causing the sieve plate to generate a vibrating screening action;

[0011] A triangular groove matching with the push plate is provided at the top of the sieve plate. When the push plate is pressed and moves horizontally, the sieve plate can be driven to turn over to discharge large-particle materials.

[0012] As a further improvement of the above technical solution:

[0016] The screening assembly further includes:

[0017] A push block provided on the side wall of the mixing box, which is connected to the push plate through a spring;

[0018] The sieve plate maintains a horizontal screening state under the action of a torsion spring. When the end of the push plate is inserted into the triangular groove, the sieve plate is driven to incline around the first rotating shaft to form a discharge inclined plane.

[0020] An adjusting block fixedly connected to the adjusting screw rod, and anti-slip threads are provided on its outer surface;

[0021] A sliding plate, and the sliding plate forms a screw pair with the adjusting screw rod to convert the rotational motion into the lateral displacement of the limiting triangular block.

[0022] It further includes:

[0023] A detachable feed hopper, and strip-shaped grooves for clamping with the top of the mixing box are provided on both sides of its bottom;

[0024] The top of the mixing box is provided with limiting inclined blocks for supporting the feed hopper to form a three-point positioning structure.

[0025] The transmission mechanism of the semi-gear and the rack specifically includes:

[0026] A semi-gear fixed to the end of the second rotating shaft;

[0028] A second connecting cross bar connecting the rectangular frame;

[0029] And a tension spring connecting the mixing box and the side connecting block to form a reciprocating motion mechanism.

[0030] The rotation axis of the rotating plate deviates from the geometric center, so that it automatically fits the inclined surface of the discharge chute under the action of gravity;

[0031] The working surface inclination angle of the limiting triangular block matches the locking angle of the rotating plate to form a self-locking structure.

[0032] A production process of biochar-based microbial fertilizer is applied to a production device of biochar-based microbial fertilizer as described above, and specifically includes the following steps:

[0033] S1. Feeding: The feeding hopper is lapped on the top of the mixing box and is ensured to be stable by clamping with the limiting inclined block. After the material is poured in, it is concentrated between the two crushing rollers;

[0034] S2. Crushing: The servo motor drives one crushing roller, and the two crushing rollers rotate through the spur gear transmission. The circular protrusions crush the material;

[0035] S2. Screening: A second rotating shaft drives the half gear, so that the rack moves, and the rectangular frame drives the sieve plate to vibrate, and the material is filtered on the sieve plate;

[0036] S2. Discharge of small particles: The small particle material passes through the inside of the mixing box, falls on the rotating plate, and slides out along a discharge chute for collection;

[0037] S2. Adjustment of the rotating plate: Rotate the adjusting block, and the rotating plate is turned to another discharge chute through the adjusting screw rod, etc., for subsequent operations;

[0038] S2. Discharge of large particles: Push the pushing block, and the sieve plate rotates through the pushing plate, etc. The large particle material slides out along the inclined surface of the sieve plate and is discharged through another discharge chute.

[0039] In this application, when in use, the feeding hopper can be lapped on the top of the mixing box, is clamped with the two sides of the mixing box through the strip-shaped grooves, and at the same time, the four limiting inclined blocks respectively support the side surface of the feeding hopper, which can ensure the stability of the feeding hopper. It can not only help the material enter the device, but also make the material concentrated between the two crushing rollers, facilitating the grinding of the material. Subsequently, the feeding hopper can be quickly removed, which is convenient for the user to clean the crushing rollers;

[0040] Start the servo motor. The output shaft of the servo motor can drive one of the crushing rollers to rotate. The crushing roller drives the second rotating shaft to rotate. The second rotating shaft drives the spur gear to rotate. Through the meshing of the two spur gears, the crushing roller on the other side can be driven to rotate. The crushing roller drives a plurality of circular protrusions to rotate, and the plurality of circular protrusions can crush the material, thus facilitating the subsequent mixing process;

[0041] And one of the second rotating shafts can drive the half gear to rotate, the half gear drives the rack to move laterally, the rack drives the first connecting cross bar to move laterally, the first connecting cross bar drives the side connecting block and the second connecting cross bar to move laterally, the side connecting block stretches the tension spring, and the second connecting cross bar drives the rectangular frame to move laterally. After the material is crushed, it falls on the top of the screen plate for filtering, and the rectangular frame drives the material on the screen plate to vibrate, which can help the screening process to proceed normally and improve the screening efficiency.

[0042] The smaller particles of materials after screening can pass through the inside of the mixing box, fall on the surface of the rotating plate, and slide out along one of the discharging chutes. At this time, the materials that meet the specifications after screening can be collected uniformly. When the screening is completed, when it is necessary to remove the larger particles of materials remaining on the surface of the screen plate, there is no need to remove the collection box that collects the materials that meet the specifications.

[0043] It is only necessary to rotate the adjustment block, the adjustment block drives the adjustment screw to rotate, the adjustment screw drives the sliding plate to move horizontally, and the sliding plate drives the two limit triangle blocks to move horizontally. At this time, the two limit triangle blocks no longer interfere with the two sides of the rotating plate, and the rotating plate can be adjusted from one side of the discharging chute to the other discharging chute. The adjustment block is rotated in the opposite direction again, and the adjustment block drives the two limit triangle blocks to reset, thereby limiting the rotating plate at another angle, so that the material can be discharged toward the other discharging chute.

[0044] At this time, the pushing block can be pushed, and the pushing block drives the pushing plate to move horizontally. The pushing block squeezes the spring, and one end of the pushing plate extends to the inside of the mixing box, and contacts the triangular groove through one end of the pushing plate, thereby driving the screen plate to rotate, and the screen plate drives the first rotating shaft to rotate and twist the torsion spring, so that the larger particles of material remaining on the surface of the screen plate can be discharged along the inclined surface of the screen plate, and then the discharging process can be realized through another discharging chute, so that there is no need to frequently replace heavier material boxes, reducing the workload of workers.

[0045] Beneficial effects: 1. The feed hopper can be overlapped on the top of the mixing box and connected to the mixing box through the strip groove. Four limit inclined blocks support the side to ensure the stability of the feed hopper, making it easy for materials to enter the device and concentrate between the crushing rollers. It can also be quickly removed to facilitate cleaning of the crushing rollers.

[0046] 2. The servo motor drives one of the crushing rollers to rotate, and drives the other crushing roller to rotate through the meshing of the spur gears. Multiple circular protrusions crush the material to facilitate subsequent mixing.

[0047] 3. The rotation of the crushing roller drives the half gear to rotate, which in turn drives the rack, the first connecting cross bar, the side connecting block, the second connecting cross bar and the rectangular frame to move laterally. The rectangular frame drives the material on the screen plate to vibrate, which helps the screening process to proceed normally and improves the screening efficiency.

[0048] 4. The smaller screened granular materials can pass through the inside of the mixing box, fall on the surface of the rotating plate and slide out along the discharge chute. After screening, the adjusting block is rotated to drive the adjusting screw rod to rotate, so that the sliding plate and the limiting triangular block move horizontally, and the orientation of the rotating plate can be adjusted to discharge the materials to another discharge chute, without the need to frequently replace the feed box, reducing the workload of workers.

[0049] 5. Push the pushing block to drive the pushing plate to move horizontally. The pushing plate abuts against the triangular groove, drives the sieve plate to rotate and twist the torsion spring, so that the larger granular materials remaining on the surface of the sieve plate are discharged along the inclined plane, and the discharging is realized through another discharge chute.
