Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] The utility model provides a tea sifting machine for collecting tea powder, comprising: a frame 1, a vibration motor 2, a sieve plate 3, and a spring bracket 4;

[0027] The frame 1 is provided with a plurality of spring brackets 4, on which a sieve plate 3 is commonly provided, on which a vibration motor 2 is provided, the sieve plate 3 is an inclined plate with sieve holes, a notch 8 penetrating the sieve plate 3 is provided at the lowest point of the inclined plate of the sieve plate 3, a hopper 7 for accommodating screened tea leaves is provided outside the notch 8, a residue hopper 5 is provided below the sieve plate 3, and a residue collecting bucket 6 is provided below the residue hopper 5;

[0028] The residue hopper 5 is fixedly connected to the sieve plate 3, and the residue collecting barrel 6 and the residue hopper 5 are connected by a connecting tube 9. The connecting tube 9 is rotatably installed with an active pressing wheel 10 and a driven pressing wheel 12. The lower opening of the residue hopper 5 faces the gap between the active pressing wheel 10 and the driven pressing wheel 12. The residue hopper 5 is equipped with a driving device for driving the active pressing wheel 10 and the driven pressing wheel 12 to move toward each other. After the vibration motor 2 is started, it starts to filter and remove impurities from the tea leaves on the sieve plate 3. The tea leaves remain on the sieve plate 3. After the tea powder is screened, it falls between the active pressing wheel 10 and the driven pressing wheel 12 and is squeezed, thereby improving its compactness, compressing the volume, reducing space occupancy, reducing the frequency of replacing or emptying the collection container, and improving production efficiency.

[0029] The driving device includes a driving tooth 11, a driven tooth 13, a rack 14, a sleeve 15, a sliding block 16, a rack 14, and a ratchet 18;

[0030] The active pressing wheel 10 is provided with a first connecting shaft extending out of the connecting cylinder 9, and the portion of the first connecting shaft extending out of the connecting cylinder 9 is equipped with a driving tooth 11, and the passive pressing wheel is provided with a second connecting shaft extending out of the connecting cylinder 9, and the portion of the second connecting shaft extending out of the connecting cylinder 9 is equipped with a driven tooth 13, the driving tooth 11 and the driven tooth 13 are meshingly connected, and a ratchet 18 is connected between the driving tooth 11 and the first connecting shaft, and the meshing direction of the ratchet 18 is the direction in which the active pressing wheel 10 and the driven pressing wheel 12 move toward each other.

[0031] The residue hopper 5 is provided with a sleeve 15, the axial direction of the sleeve 15 is parallel to the vibration direction of the vibration motor 2, a sliding block 16 is slidably installed in the sleeve 15, a rack 14 is installed at the lower end of the sliding block 16, and the rack 14 is meshed with the active gear 11 for transmission. The physical characteristics of the vibration screen are used for driving, and the fallen tea powder is pre-compressed. The one-way transmission realized by the ratchet 18 can continuously squeeze the tea powder that falls between the active pressing wheel 10 and the driven pressing wheel 12 and continuously transfer it downward without the tea powder overflowing upward.

[0032] Buffer springs 17 are provided at both ends of the sleeve 15, and both ends of the two buffer springs 17 are respectively connected to the ends of the sliding block 16 and the sleeve 15. The buffer springs 17 can prevent the rigid impact between the sliding block 16 and the sleeve 15 from damaging the sliding block 16 or the sleeve 15, and at the same time reduce the rigid impact on the sliding block 16 during startup and shutdown.

[0033] The inner wall of the connecting cylinder 9 is provided with a scraper for scraping off the adhesion of the active pressing wheel 10 and the driven pressing wheel 12. The scraper is detachably connected to the connecting cylinder 9. The placement position of the scraper is lower than the lower side of the axis connecting the active pressing wheel 10 and the driven pressing wheel 12. The scraper can reduce the adhesion on the active pressing wheel 10 and the driven pressing wheel 12, avoid the adhesion on the active pressing wheel 10 or the driven pressing wheel 12 from being repeatedly squeezed to affect the efficiency of compacting the tea powder, and ensure that the adhesion can pass through the active pressing wheel 10 and the driven pressing wheel.

[0034] The sliding block 16 is made of lead alloy, which has a high density and low hardness. The sliding block 16 itself is only used for counterweight. The use of lead alloy can effectively reduce the volume of the sliding block 16. At the same time, because the hardness of lead alloy is low, it naturally has the characteristic of absorbing kinetic energy, which can further reduce disordered vibration and improve stability.

[0035] The active pressure wheel 10 and the driven pressure wheel 12 are hollow resin materials, and the rack 14, the active teeth 11, and the driven teeth 13 are all made of resin materials. The resin material can be self-lubricating and self-cleaning polyoxymethylene or nylon. In addition to good mechanical properties, it has high elastic modulus, high hardness and rigidity, etc., and also has excellent anti-fatigue properties. It is particularly suitable for gear products subjected to repeated external forces and parts that continuously vibrate. It is particularly suitable for use as a force-bearing component, thereby further extending the service life.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
