Description

Technical Field

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

[0002] Sunflower seeds, which are the fruits of sunflowers, can be used for food and oil. Sunflower seeds are one of the important oil crops with a yield second only to soybeans. Sunflower seeds have extremely high nutritional value, therapeutic value and medical value, and are used in a considerable amount. At present, before the sunflower seeds are shelled, a screening device is required to screen the sunflower seeds according to grade. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a sunflower seed screening device with a publication number of CN216500769U, which includes a base. The sunflower seed screening device is provided with a fan, and people pour the sunflower seeds to be screened into a discharge barrel. In this process, people turn on the fan through an external controller, and the fan blows out the shriveled seeds and impurities in the sunflower seeds from the reserved opening through cooperation with the jet plate. The impurities are blown farther because of their light weight, and the shriveled seeds fall into the receiving frame due to gravity. The sunflower seeds after wind selection fall into the first screening frame. At the same time, the driving motor is started to drive the crankshaft to rotate, and the right movable plate is squeezed through cooperation with the ring and the connecting rod. Through the cooperation of the compression spring, the left and right movable plates drive the first screening frame and the second screening frame to vibrate and screen left and right, thereby improving the screening effect of the screening device, greatly improving the practicality of the device, and facilitating people to use it.

[0004] In actual use, the above utility model uses a screening component to screen sunflower seeds. The capacity of the first screening frame and the second screening frame is certain. After the sunflower seeds are filled, the operator needs to turn off the machine and take out the sunflower seeds. The sunflower seeds in the first screening frame will fall directly onto the base, and the two sets of screening frames will also be blocked, both of which need to be cleaned by the operator, which increases the workload of the operator and reduces the practicality of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0036] Working principle:

[0037] When the sunflower seed shelling screening device is actually used, sunflower seeds are added first. When the sunflower seeds exceed the processing capacity of the fan 31, the shriveled sunflower seeds and dust will fall into the vibrating screen below. When the sunflower seeds fall, they are blocked by the unloading roller 6 and the unloading blades 7. The unloading roller 6 rotates, so that the amount of sunflower seeds falling is not excessive. The wind generated by the fan 31 blows out the shriveled and dust mixed between the falling sunflower seeds through the discharge square tube 11. Sunflower seeds with good quality fall on the surface of the first vibrating screen 5. The set unloading roller 6 can ensure that the fan 31 blows the peanut seeds clean, thereby improving the product quality produced by the sunflower seed shelling screening device. At the same time, the forward and reverse motor 12, the first vibrating screen 5 and the second vibrating screen 2 work, and the sunflower seeds fall on the first vibrating screen 5. The sunflower seeds whose size is larger than the sieve holes of the first vibrating screen 5 are subjected to vibration and gravity and slide to the first unloading screen. The sunflower seeds with a size smaller than the sieve holes of the first vibrating screen 5 fall on the second vibrating screen 2 for secondary screening. After the secondary screening, the sunflower seeds can be discharged from the second discharging hopper 3 and the discharging square tube 18. During the screening, the forward and reverse motors 12 drive the rotating shaft 27 to rotate, and the rotating shaft 27 drives the two sets of active bevel gears 23 to rotate. The two sets of active bevel gears 23 respectively drive the two sets of threaded rods 21 to rotate through the two sets of driven bevel gears 24. The rotation of the two sets of threaded rods 21 can drive the two sets of moving plates 20 to move. The brushes 19 on the two sets of moving plates 20 can clean the blocked first vibrating screen 5 and the second vibrating screen 2. By setting the brushes 19, the first vibrating screen 5 and the second vibrating screen 2, the screened sunflower seeds can be automatically discharged, and the vibrating screen can be prevented from being blocked, thereby improving the practicality of the screening device for sunflower seed shelling.
