Description
Technical Field
[0001] The utility model relates to the technical field of defective product screening devices, in particular to a defective product screening device. Background Art
[0002] After drying, the tea leaves will curl and shrink into long needles. The properties of the tea leaves will change after drying, and they will become more brittle. In addition, the sizes of the tea leaves are also different. Therefore, a tea screening device is needed to screen the tea leaves according to their completeness and individual size, and to classify the tea leaves.
[0003] After preliminary screening, tea leaves are divided into multiple grades. Among them, inferior tea leaves contain more residues, which requires workers to use the sieve to shake and screen multiple times. During the screening process, tea leaves are prone to partial stacking, which will block the sieve holes. Some impurity particles will also be stuck inside the sieve holes, which will also cause blockage and affect the screening efficiency of impurities. Therefore, a defective screening device is needed to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] Reference Figure 1-4 A defective product screening device includes a screening device 1, the screening device 1 includes a screening bucket 11, two lining plates 13 are symmetrically connected to the inner side of the top of the screening bucket 11, a filter plate 14 is placed on the surface of the lining plate 13, a sweeping assembly 3 is installed on the top of the screening bucket 11, and the sweeping assembly 3 includes a cover plate 31, and two pushing components 33 are symmetrically installed at the bottom of the cover plate 31. The left and right sides of the cover plate 31 are symmetrically connected to positioning shafts 32, and the positioning shafts 32 are inserted into the side of the screening bucket 11 through a slot, and the pushing component Component 33 includes a driving motor 332, which is fixed on the surface of the cover plate 31. The output end of the driving motor 332 passes through the cover plate 31 and is connected to a telescopic shaft 333, and the bottom end of the telescopic shaft 333 is connected to a connecting plate 334. A plurality of blades 335 are connected around the outer side of the bottom end of the connecting plate 334. A protective cover 331 is installed on the outer side of the driving motor 332, and the protective cover 331 is fixed to the surface of the cover plate 31 by bolts. A shaking component 2 is arranged on the outer side of the bottom end of the screening bucket 11.
[0024] The surface of the blade 335 is provided with hollow holes, and the blade 335 is arranged at an inclination.
[0025] The telescopic shaft 333 is composed of a shaft cylinder end, an inner shaft end and a supporting spring end, and the inner shaft end of the telescopic shaft 333 is a polygonal structure.
[0026] Both sides of the inner wall of the screening bucket 11 are inclined structures, and a discharge pipe 12 is connected to the left side of the bottom end of the screening bucket 11.
[0027] The side of the filter plate 14 is in contact with the inner wall of the screening bucket 11 , and the side of the filter plate 14 is fixedly connected to the screening bucket 11 by means of locking bolts 15 .
[0028] The shaking assembly 2 includes four elastic accessories 21 , the bottom ends of the elastic accessories 21 are connected to pillars 22 , and a vibrator 23 is installed on the right side of the bottom end of the screening bucket 11 .
[0029] The elastic accessory 21 includes a docking block 211 connected and fixed to the screening bucket 11, a docking plate 212 is docked at the bottom of the docking block 211, a return spring 213 is connected to the bottom of the docking plate 212, and a docking block 214 is connected to the bottom of the return spring 213, and a sleeve plate 215 is connected to the side of the docking plate 212.
[0030] The hollow hole setting of the blade 335 can reduce the contact degree with the tea leaves, thereby reducing the damage to the tea leaves when pushing. When the blade 335 rotates, the inclined setting of the blade 335 can easily turn over the tea leaves, so that the impurity particles in the tea leaves can leak out, and the impurity particles can be filtered conveniently. When the cover plate 31 is buckled on the top surface of the screening bucket 11, the elastic force of the supporting spring end is used to support and push the inner shaft end, so that the blade 335 can resist the surface of the filter plate 14. When the blade 335 rotates, the blade 335 can ensure the effect of scooping, turning and pushing the tea leaves. The inclined structural design of the blade 335 can facilitate the turning of the tea leaves during rotation, so that the impurity particles can fall after moving on the surface of the filter plate 14, and then the impurity particles can be controlled for filtering. When the filter plate 14 is placed on the surface of the liner 13 When the filter plate 14 is in the filter state, the locking bolt 15 can be passed through the side of the filter plate 14 and then inserted into the screening bucket 11, so that the filter plate 14 can be constrained and fixed to prevent the filter plate 14 from loosening during shaking. By starting the vibrator 23, the screening bucket 11 can be controlled to vibrate. During the vibration of the screening bucket 11, the filter plate 14 can be controlled to shake, so that the separated impurity particles can fall quickly. When the screening bucket 11 drives the docking block 211 to shake, the docking block 211 can control the connecting plate 212 to move. The shaking of the connecting plate 212 can continuously compress and restore the reset spring 213, so that the screening bucket 11 can be controlled to shake, thereby increasing the shaking frequency of the screening bucket 11. When the connecting plate 212 moves, the sleeve plate 215 can cooperate with the connecting block 214, so as to control the connecting plate 212 to move up and down stably above the connecting block 214.
[0031] Working principle: According to the attached Figure 2 With attached Figure 3As shown, by placing the filter plate 14 flat on the surface of the lining plate 13, and inserting the locking bolt 15 through the side of the filter plate 14 and then inserting it into the threaded hole of the screening bucket 11, the tea leaves can be laid on the surface of the filter plate 14. At this time, the vibrator 23 can be started to drive the docking block 211 to move, and the docking block 211 can drive the connecting plate 212 to move, so that the connecting plate 212 drives the sleeve plate 215 to jump up and down on the surface of the connecting block 214, and the filter plate 14 is controlled to shake during the shaking of the screening bucket 11, and then the tea leaves can be screened;
[0032] Secondly, according to the attached Figure 4 As shown, the staff can insert the positioning shaft 32 into the side slot of the screening bucket 11, start the driving motor 332, and make the output end of the driving motor 332 control the telescopic shaft 333 to drive the connecting plate 334 to rotate. The connecting plate 334 can drive the blade 335 to sweep the tea leaves laid on the surface of the filter plate 14, so that the impurity particles in the tea leaves can fall off quickly. After the impurity particles fall into the screening bucket 11 through the pores of the filter plate 14, they fall out from the discharge pipe 12 to complete the screening.
