TECHNICAL FIELD
[0001] The utility model relates to the seed production technical field, and specifically is a sunflower seed screening dust removal device. BACKGROUND
[0002] Sunflower, because the inflorescence rotates with the sun, is named. It is an annual tall herbaceous plant, and its edible seeds can be processed into oil or fat sources for human consumption, can be used as animal feed and possible alternative fuel sources, and can also be used as ornamental plants. Sunflower seeds need to be processed after harvesting, and before processing, different specifications and quality sunflower seeds need to be screened, and dust mixed in the sunflower seeds also needs to be removed. However, the existing processing device has a single function, and dust removal and seed screening need to be carried out separately, which makes the sunflower seed processing time-consuming and low in work efficiency. Therefore, a sunflower seed screening dust removal device that can comprehensively process sunflower seeds and improve work efficiency needs to be developed. SUMMARY
[0003] In view of the above technical problems, the utility model provides a sunflower seed screening dust removal device that can comprehensively process sunflower seeds and improve work efficiency to solve the problems of long processing time and low work efficiency of existing sunflower seeds.
[0004] To solve the above technical problems, the sunflower seed screening dust removal device comprises a shell, a feed pipe fixedly connected to the top of the shell, a material collecting hopper fixedly connected to the bottom of the shell, a discharge pipe fixedly connected to the bottom of the material collecting hopper, an air inlet fan fixedly connected to one side of the upper part of the shell and a dust collecting box fixedly connected to the other side of the upper part of the shell, a dust collecting cloth bag detachably connected to the lower part of the dust collecting box, two symmetrical through grooves formed in the middle of the shell, a sieve plate inserted into the through groove, a support block fixedly connected to the shell below the through groove, an iron block and a guide sleeve fixedly connected to the bottom of the sieve plate on both sides, an electromagnet fixedly connected to the outside of the support block and a guide rod fixedly connected to the inside of the support block, the iron block being magnetically connected to the electromagnet, the guide rod being slidably connected to the guide sleeve, and a spring sleeve being arranged on the guide rod.
[0005] Further, a filter screen is fixedly connected to the upper part of the dust collecting box, and a ventilation hole is formed in the top of the dust collecting box.
[0006] Further, a supporting leg is fixedly connected to the bottom of the material collecting hopper.
[0007] Further, a foreign matter outlet is formed in the shell on both sides of the sieve plate.
[0008] Compared with the prior art, the utility model has the following advantages:
[0009] This invention features an intake fan at the top of the casing, which blows lighter impurities, such as dust and shriveled seeds, into the dust collection box. The sieve plate then separates the qualified sunflower seeds from other heavier and larger impurities. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] Figure 2 This is a side view of the present invention.

Electromagnet, 11. Guide rod, 12. Iron block, 13. Guide sleeve, 14. Spring, 15. Filter screen, 16. Support leg. Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings.
[0014] like Figure 1 , 2 The sunflower seed screening and dust removal device shown includes a housing 1, with a feed pipe 2 fixedly connected to the top of the housing, a collection hopper 3 fixedly connected to the bottom of the housing 1, and a discharge pipe 4 fixedly connected to the bottom of the collection hopper 3. In order to remove and collect dust and lighter impurities mixed in the sunflower seeds, an inlet fan 5 is fixedly connected to one side of the upper part of the housing 1, and a dust collection box 6 is fixedly connected to the other side. A dust collection bag 7 is detachably connected to the lower part of the dust collection box 6. In order to separate the sunflower seeds that meet the requirements from the heavier and larger impurities, two through slots are symmetrically opened in the middle of the housing 1. A sieve plate 9 is inserted into the through slot. A support block 8 that penetrates the housing 1 is symmetrically fixedly connected below the through slot. Iron blocks 12 and guide sleeves 13 are fixedly connected to the bottom two sides of the sieve plate 9. An electromagnet 10 is fixedly connected to the outside of the support block 8, and a guide rod 11 is fixedly connected to the inside. The iron blocks 12 are magnetically connected to the electromagnet 10. One end of the guide rod 11 is slidably connected to the guide sleeve 13. A spring 14 is sleeved on the guide rod 11.
[0015] To prevent dust and light impurities from being carried out when the gas is discharged from the housing 1, a filter screen 15 is fixedly connected to the upper part of the dust collection box 6, and a ventilation hole is provided on the top of the dust collection box 6.
[0016] To improve the stability of the device, the bottom of the hopper 3 is fixedly connected with support legs 16.
[0017] In order to remove impurities, impurity outlets are provided on both sides of the shell 1 on both sides of the sieve plate 9.
[0018] The working process of this embodiment is as follows:
[0019] In use, the sunflower seeds from the feed tube 2 into the shell 1, in the sunflower seeds falling, by the fan 5 air supply, the wind will dust and part of the quality of small light blowing into the dust bag 6, dust, light into the dust bag 7, the wind is filtered through the mesh 15 to the top, the sunflower seeds fall on the sieve plate 9, through intermittent power supply to the electromagnet 10, the sieve plate 9 vibration, specifications meet the requirements of the sunflower seeds through the sieve plate aperture into the hopper 3, and through the discharge pipe 4 exit device. At this time only one side of the electromagnet 10 power, so that the sieve plate 9 tilt, at this time the material left on the sieve plate 9 under the influence of gravity from the shell 1.
