Technical Field

[0001] The utility model relates to the technical field of forage seeds, in particular to a forage seed screening device. Background Art

[0002] Forage seed screening refers to the process of separating forage seeds by size using sieves with different apertures. This step is critical in forage seed production because it helps remove impurities, broken seeds and other unwanted particles, thereby ensuring the purity and quality of the seeds. Through screening, forage seeds of different particle sizes can be obtained to meet different sowing and production needs. Screening usually uses equipment such as vibrating screens or rotary screens, which can efficiently complete the screening task and improve the processing efficiency of forage seeds.

[0003] When personnel actually use the screening device to operate on forage seeds, debris mixed with the forage seeds will be adsorbed inside the screening device, so that personnel need to open the device regularly to perform maintenance and cleaning operations on the residues inside, which increases the workload of personnel and affects the screening operation to a certain extent. Therefore, a forage seed screening device is proposed. Utility Model Content

[0007] Preferably, both sides of the outer ring of the fan are fixedly connected with sliders, and both side inner walls of the outer frame are provided with sliding grooves adapted to the sliders.

[0008] Preferably, a screw rod is vertically arranged in the inner cavity of the outer frame, the bottom of the screw rod passes through the adjacent slider through a screw sleeve and is rotatably connected to the bottom of the inner cavity of the outer frame through a rotating shaft, and the top of the screw rod passes through the top of the inner cavity of the outer frame through a shaft sleeve and extends to the top of the outer frame.

[0009] Preferably, a motor is installed on the top of the outer frame, and the output shaft of the motor is drivingly connected to the extended end of the adjacent lead screw.

Under the influence of gravity, the grass seeds first contact with the filter screen 1 for screening, and the debris is intercepted at the first time. The grass seeds that meet the requirements fall onto the filter screen 2 for secondary screening. Finally, the grass seeds that fully meet the requirements are discharged outward through the discharge hopper. At this time, the debris remaining on the filter screen 1 slides along the direction of the filter screen 1 to the filter screen 2, and then moves toward the inside of the storage box by the filter screen 2, and finally falls into the inside of the storage box through the discharge chute. When there is debris adsorbed on the surface of the filter screens 1 and 2, the personnel can drive the screw to rotate through the motor, so that the screw drives the corresponding screw sleeve and the slider to move. The vertical height position adjustment drives the fan to change its height position, so that the fan can suck the debris remaining on filter one onto filter two. At this time, the personnel changes the height position of the fan again, and changes the rotation direction of the fan to blow the debris adsorbed on filter two into the storage box through the discharge chute. Through the structural design, the personnel use the device to achieve a secondary screening effect for the screening of forage seeds, which ensures the screening quality while facilitating the personnel to quickly remove the debris of the forage seeds remaining inside the device, thereby ensuring the sanitary environment inside the device and reducing the steps required for personnel to manually operate the device for maintenance, bringing convenience to the users.

[0014] The utility model also has the following beneficial effects:

[0015] The setting of the slider and the slide groove ensures the stability of the fan during the position adjustment process. The setting of the outer frame protects the operation of the internal structure from being affected by external forces. The setting of the screw rod and the screw sleeve allows the height position of the motor to be driven and adjusted and the position state to be locked. The setting of the supporting legs strengthens the stable support for the bottom of the shell. The setting of the storage box and the discharge chute allows the intercepted debris to fall into the storage box for unified collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] This program has the following working process:

[0025] When the personnel use it, they feed the raw materials into the interior of the housing 1 through the feed hopper 2. Under the influence of gravity, the grass seeds first contact the filter screen 8 for screening, and the debris is intercepted at the first time. The grass seeds that meet the requirements fall on the filter screen 13 for secondary screening.

[0026] According to the above working process, we can know that:

[0027] Through the structural design, the personnel can use the device to achieve the secondary screening effect for the screening of forage seeds, which ensures the screening quality while facilitating the personnel to quickly remove the debris of the forage seeds remaining inside the device, thereby ensuring the sanitary environment inside the device and reducing the steps required for manual operation of the device maintenance, thus bringing convenience to the users.

At this time, the personnel change the height position of the fan 10 again. The personnel change the rotation direction of the fan 10, and blow the debris adsorbed on the filter screen 13 to the inside of the storage box 4 in coordination with the discharge chute 3. The stability of the fan 10 during the position adjustment process is ensured by the setting of the slider 11 and the slide chute 9. The operation of its internal structure is protected from external forces by the setting of the outer frame 6.
