Description

Technical Field

[0001] The utility model relates to the technical field of wolfberry processing equipment, in particular to a wolfberry screening device. Background Art

[0002] In order to facilitate the preservation of wolfberries, wolfberries are generally dried or sun-dried into dried wolfberries. Therefore, in the production and processing of wolfberries, a screening device is used to screen wolfberries to remove impurities mixed in the wolfberries, thereby improving the quality of wolfberries and ensuring their later use.

[0003] In the Chinese patent with the publication number CN219253188U, a wolfberry screening device is disclosed. In use, by setting connecting rods, shriveled or small grains can fall out through the gaps between the connecting rods and enter the interior of the empty slots to screen the wolfberries. Through the operation of the servo motor, the fixed plate and each connecting rod can be driven to rotate. Thus, the plump grains remaining in the gaps between the connecting rods during screening will rotate upward, slide out after rotating a certain height and fall back to the bottom again. Therefore, when continuously putting wolfberries for screening, the problem of screening blockage can be effectively avoided. However, when the above wolfberry screening device is in use, a cylindrical screening device composed of multiple connecting rods, a fixed plate and a fixing ring is used, and the wolfberries are screened by using the rotating screening device and the height difference. However, during the use process, a large amount of dust will remain in the screening device, which easily causes too much dust to adhere to the surface of the wolfberries, affecting the quality of the screened wolfberries and increasing the defective rate of wolfberry production. Therefore, we propose a wolfberry screening device. Summary of the Utility Model

[0024] To enable those skilled in the art to better understand the technical solution of the present utility model, the following will further introduce the present utility model in detail with reference to the accompanying drawings.

[0025] The present utility model provides a goji berry screening device as Figure 1 shown, including:

[0026] A support base 1, a main screening frame 2 for screening goji berries is arranged in the middle of the support base 1, a screening plate is arranged at the bottom of the main screening frame 2, a plurality of screening holes are opened on the screening plate, and a waste bin 3 for collecting impurities and inferior goji berries is arranged on one side of the main screening frame 2;

[0027] As can be seen from the above, during use, after putting the goji berries into the interior of the main screening frame 2, shake the main screening frame 2, and screen the goji berries through the screening net inside the main screening frame 2, so as to complete the screening and processing of the goji berries, which is convenient for the subsequent processing of the goji berries.

[0028] Refer to Figures 1-4 shown, two screening devices 4 are arranged between the support base 1 and the main screening frame 2. The screening device 4 includes a motor 401 and a lifting rod 406. The motor 401 is fixed at one end of the support base 1, one end of the lifting rod 406 is fixed at one end of the main screening frame 2, a transmission mechanism is arranged between the motor 401 and the lifting rod 406, and the lifting rod 406 is in an L shape composed of two rectangular plates spliced together;

[0029] The transmission mechanism includes a driving disk 402 and a transmission disk 403. The bottom of the driving disk 402 is fixed on the output shaft of the motor 401, the transmission disk 403 is fixed to the end of the lifting rod 406 away from the main screening frame 2. A plurality of main power blocks 404 are fixed on the top of the driving disk 402, a plurality of sub-power blocks 405 are fixed on the bottom of the transmission disk 403. The plurality of main power blocks 404 and the plurality of sub-power blocks 405 are arranged on the opposite sides of the driving disk 402 and the transmission disk 403, and a main spring 415 is arranged between the driving disk 402 and the transmission disk 403. The free end of the main spring 415 is in contact with the driving disk 402;

[0030] A limiting rod 409 is arranged in the middle of the main screening frame 2. A positioning rod is fixed at the bottom of the limiting rod 409, and both ends of the positioning rod are respectively fixed to both sides of the support base 1. The opposite sides of the plurality of main power blocks 404 and the plurality of sub-power blocks 405 are provided with adapted inclined surfaces; A baffle is fixed at the top of the limiting rod 409, the width of the baffle is greater than the width of the limiting rod 409, and a fan 407 for blowing air is arranged on the top of the support base 1. Through the fan 407, dust, impurities and shriveled goji berries can be blown into the interior of the waste bin 3.

[0031] By adopting the above technical solutions:

[0032] During use, the output shaft of the motor 401 drives the drive disk 402 to rotate. The drive disk 402 drives the main power block 404 to rotate. At the contact between the inclined surface of the main power block 404 and the inclined surface of the secondary power block 405, the main power block 404 pushes the secondary power block 405 to move upward. The secondary power block 405 drives the transmission disk 403 to move upward. The transmission disk 403 pushes the lifting rod 406 to move upward. The lifting rod 406 drives the main screening frame 2 to move upward. At the same time, the transmission disk 403 stretches the main spring 415 to deform. The elastic force of the lifting rod 406 drives the transmission disk 403 to move downward, so that the transmission disk 403 drives the main screening frame 2 to reciprocate through the lifting rod 406, separating the goji berries and dust inside the main screening frame 2. The dust is blown into the waste bin 3 by the fan 407 to prevent the dust from falling into the screened goji berries, thereby improving the quality of the screened goji berries.

[0033] In addition, as shown in Figures 1-4 a movable swing block 411 is provided at one end of the moving rod 410 away from the transmission disk 403. Slide rods 412 are fixed on both sides of the swing block 411. One end of the slide rod 412 away from the swing block 411 is connected to the support base 1. A secondary screening frame 408 is fixed on one side of the swing block 411 away from the moving rod 410. A filter plate is provided at the bottom of the secondary screening frame 408, and a plurality of filter holes are provided on the filter plate, which can perform secondary screening on the goji berries screened inside the main screening frame 2 and distinguish the grades and volumes of the goji berries for the second time; a stop disk 414 is fixed on the outer wall of the slide rod 412, and a secondary spring 413 is provided between the stop disk 414 and the support base 1; one end of the slide rod 412 away from the swing block 411 penetrates through the support base 1 and is fixed with a clamping plate, and the diameter of the clamping plate is larger than the diameter of the slide rod 412. An inclined groove adapted to the moving rod 410 is provided on one side of the swing block 411.

[0034] By adopting the above technical solution:

[0035] During use, when the transmission disk 403 reciprocates downward, the smaller goji berries inside the main screening frame 2 fall into the secondary screening frame 408. The transmission disk 403 drives the moving rod 410 to reciprocate up and down. The moving rod 410 cooperates with the inclined groove of the swing block 411 to push the swing block 411 to reciprocate left and right. The swing block 411 drives the slide rod 412 to reciprocate left and right. The slide rod 412 drives the stop disk 414 to reciprocate. The stop disk 414 drives the secondary spring 413 to deform, so that the elastic force of the secondary spring 413 pushes the stop disk 414 to move. The stop disk 414 drives the stop disk 414 through the slide rod 412 to move, so that the swing block 411 drives the secondary screening frame 408 to vibrate rapidly, performing secondary screening on the goji berries that fall into the secondary screening frame 408 after being separated inside the main screening frame 2, facilitating people to perform secondary classification on the grades and goji berries of the goji berries and improving the convenience of the device.
