Description

Technical Field

[0001] The utility model relates to the field of tea processing, in particular to a tea screening device capable of collecting in layers. Background Art

[0002] Tea is the leaves and buds of the tea tree and can be made into a drink after processing. Stir-frying tea is an important process in the tea processing. By heating and stir-frying the tea in a pot, the purposes of drying the tea, terminating fermentation, shaping the tea appearance, and stimulating the tea aroma can be achieved. However, broken tea residues will be generated during the stir-frying process. The substances in these broken tea residues are released relatively quickly, which may cause the tea soup to be too strong or bitter. Therefore, the tea needs to be screened after stir-frying.

[0003] However, the stir-fried tea has shrunk and dried, and its weight has become lighter. It is not only more difficult to jump on the vibrating sieve plate, but also the hardened edges and corners of the tea and the scraping hooks of the sieve mesh are not conducive to the tea sliding down on the vibrating sieve plate along the gravity, thus affecting the screening efficiency.

[0004] Therefore, aiming at the situation that the stir-fried tea is not only more difficult to jump on the vibrating sieve plate, but also more difficult to slide down on the vibrating sieve plate along the gravity, thus affecting the screening efficiency, a tea screening device capable of collecting in layers can be designed to solve the above problems. Content of the Utility Model

[0005] In order to overcome the problem that when screening the broken residues in the stir-fried tea, the stir-fried tea becomes hardened and lighter due to shrinkage and drying, so it is more difficult to jump on the vibrating sieve plate, and its hardened edges and corners and the scraping hooks of the sieve mesh are not conducive to the tea sliding down on the vibrating sieve plate along the gravity, thus affecting the screening efficiency.

[0006] The technical solution of the utility model is: a tea screening device capable of collecting in layers, which includes a sieve mesh plate, a receiving tray arranged at the lower end of the sieve mesh plate, a discharging tray installed at the front ends of the sieve mesh plate and the receiving tray, and further includes a screening component installed on both sides of the receiving tray, and a slag removing component arranged at the upper end of the receiving tray; the screening component includes a cushion beam, an inclined angle, a rotating shaft, a first tooth column, a second tooth column, a sprocket, a chain, a cushion column, a tooth ring groove, and a driving motor; the slag removing component includes a funnel, a first vibrator, a slag screening mesh, a dust suction hood, and a dust collector.

[0007] Preferably, when the driving motor rotates the first tooth column and the rotating shaft at the rear end through the second tooth column on one side, the sprocket and the chain will rotate the first tooth column and the rotating shaft at the front end synchronously through the second tooth column on the other side, so that the two rotating shafts rotate counterclockwise around the second tooth column at the same time. Furthermore, both the front and rear halves of the sieve tray will perform a large-amplitude circular motion around the second tooth column. Also, because the front and rear ends of the sieve tray are flat, the tea leaves will continuously fly forward and upward under the action of inertia during the undulation of the sieve tray, and will be turned over by a certain amplitude before falling, so that the tea leaves can more easily move forward on the sieve tray, and the smaller tea leaves are more likely to fall off the sieve tray for screening; the speed at which the tea leaves fall onto the sieve tray is restricted by the funnel, and the first vibrator vibrates the funnel to prevent the tea leaves from blocking the funnel. Before the tea leaves fall out of the funnel, the crushed residues in them will pass through the sieve residue net and be sucked away by the vacuum cleaner through the dust suction cover and the dust suction pipe, thus ensuring the quality of the product.

[0008] Preferably, two cushion beams are fixedly connected to the lower end of the material receiving tray; bevels are provided at the upper ends of the cushion beams; rotating shafts are rotatably connected inside the cushion beams; first tooth columns are fixedly connected to both sides of the rotating shafts.

[0009] Preferably, second tooth columns are meshed with the first tooth columns; sprockets are fixedly connected to the two second tooth columns on one side; a chain is commonly installed on the sprockets; the second tooth columns are all arranged at the center of the tooth ring groove.

[0010] Preferably, the tooth ring grooves are all opened at the upper ends of the cushion columns; a driving motor is installed on the cushion column at one side of the rear end, and the driving motor is rotationally connected to the second tooth column through a coupling.

[0011] Preferably, a funnel is arranged above the rear end of the sieve tray, and the funnel is fixedly connected to the cushion column; a first vibrator is installed on the upper end surface of the funnel; a sieve residue net is installed at the rear end inside the funnel.

[0012] Preferably, a dust suction cover fixedly connected to the funnel is arranged at the rear end of the sieve residue net; a vacuum cleaner is connected to the rear end of the dust suction cover through a dust suction pipe.

[0013] Preferably, two sliders are fixedly connected to both sides of the material receiving tray; a second vibrator is installed at the lower end of the material receiving tray; a chassis is fixedly connected to the lower ends of the cushion columns together; chutes are opened on the cushion columns, and the chutes are slidably connected to the sliders; shock absorbers are installed at the bottom ends of the chutes.

[0014] The beneficial effects of the present utility model:

[0015] 1. By setting up a screening component and a slag removal component, both the front and rear halves of the sieve tray can perform a large - amplitude circular motion around the second tooth column. During the undulation of the sieve tray, the tea leaves will continuously fly forward and upward under the action of inertia and turn to a certain extent before falling. This makes it easier for the tea leaves to move forward on the sieve tray, and smaller - sized tea leaves are more likely to fall off the sieve tray for screening. Moreover, during the process of the broken tea residues falling evenly into the funnel, they will be sucked away by the vacuum cleaner through the dust suction cover and the dust suction pipe to ensure the quality of the product.

[0023] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0024] Please refer to Figures 1-6, the present utility model provides an embodiment: a tea screening device capable of layered collection, which includes a screening mesh plate 1, a material receiving plate 2 arranged at the lower end of the screening mesh plate 1, a discharge plate 3 installed at the front ends of the screening mesh plate 1 and the material receiving plate 2, and further includes a screening component installed on both sides of the material receiving plate 2 and a slag removal component arranged at the upper end of the material receiving plate 2; the screening component includes a cushion beam 401, an inclined angle 402, a rotating shaft 403, a first tooth column 404, a second tooth column 405, a sprocket 406, a chain 407, a cushion column 408, a tooth ring groove 409, and a driving motor 410; the slag removal component includes a funnel 501, a first vibrator 502, a slag screening net 503, a dust suction hood 504, and a vacuum cleaner 505; two sliders 6 are fixedly connected to both sides of the material receiving plate 2; a second vibrator 7 is installed at the lower end of the material receiving plate 2; the lower ends of the cushion columns 408 are fixedly connected to a chassis 8 together; sliding grooves 9 are respectively arranged on the cushion columns 408, and the sliding grooves 9 are slidably connected with the sliders 6; shock absorbers 10 are installed at the bottom ends of the sliding grooves 9.

[0025] Please refer to Figures 3-6 , in this embodiment, two cushion beams 401 are fixedly connected to the lower end of the material receiving plate 2; inclined angles 402 are respectively arranged at the upper ends of the cushion beams 401; rotating shafts 403 are rotatably connected inside the cushion beams 401; first tooth columns 404 are fixedly connected to both sides of the rotating shafts 403; second tooth columns 405 are meshed with the first tooth columns 404; sprockets 406 are fixedly connected to two second tooth columns 405 on one side; a chain 407 is jointly installed on the sprockets 406; the second tooth columns 405 are respectively arranged at the centers of the tooth ring grooves 409; the tooth ring grooves 409 are respectively arranged at the upper ends of the cushion columns 408; a driving motor 410 is installed on the cushion column 408 at the rear end of one side, and the driving motor 410 is rotationally connected to the second tooth column 405 through a coupling; a funnel 501 is arranged above the rear end of the screening mesh plate 1, and the funnel 501 is fixedly connected to the cushion column 408; a first vibrator 502 is installed on the upper end surface of the funnel 501; a slag screening net 503 is installed at the rear end inside the funnel 501; a dust suction hood 504 fixedly connected to the funnel 501 is arranged at the rear end of the slag screening net 503; a vacuum cleaner 505 is connected to the rear end of the dust suction hood 504 through a suction pipe.

[0026] When in use, the falling speed of the tea towards the screening mesh plate 1 is restricted by the funnel 501, and the first vibrator 502 vibrates the funnel 501 to prevent the tea from blocking the funnel 501. Before the tea falls out of the funnel 501, the crushed residues in it will pass through the slag screening net 503 and be sucked away by the vacuum cleaner 505 through the dust suction hood 504 and the suction pipe, thereby ensuring the quality of the product;

[0027] Next, when the drive motor 410 rotates the first tooth column 404 and the rotating shaft 403 at the rear end through the second tooth column 405 on one side, the sprocket 406 and the chain 407 will rotate the first tooth column 404 and the rotating shaft 403 at the front end synchronously through the second tooth column 405 on the other side, so that the two rotating shafts 403 rotate counterclockwise around the second tooth column 405 at the same time. Furthermore, the front and rear halves of the sieve tray 1 will perform a large-amplitude circular motion around the second tooth column 405. Also, since the front and rear ends of the sieve tray 1 are flat, the tea leaves will continuously fly forward and upward under the action of inertia during the undulation of the sieve tray 1, and will be flipped by a certain amplitude before falling. Thus, it is easier for the tea leaves to move forward on the sieve tray 1, and the tea leaves with smaller volume are more likely to fall off the sieve tray 1 for screening;

[0028] Meanwhile, the second vibrator 7 vibrates the material receiving tray 2, so that the tea leaves falling on the material receiving tray 2 slide forward to the front end under the action of gravity. Finally, the tea leaves with large volume are left on the sieve tray 1 and move forward, and leave the device through the discharge tray 3 at the upper end. The tea leaves with small volume move forward on the material receiving tray 2 and leave the device through the discharge tray 3 at the lower end.

[0029] Through the above steps, by setting the screening component and the slag removal component, the front and rear halves of the sieve tray 1 perform a large-amplitude circular motion around the second tooth column 405. The tea leaves will continuously fly forward and upward under the action of inertia during the undulation of the sieve tray 1, and will be flipped by a certain amplitude before falling. Thus, it is easier for the tea leaves to move forward on the sieve tray 1, and the tea leaves with smaller volume are more likely to fall off the sieve tray 1 for screening. Moreover, during the process of the tea leaves falling evenly into the funnel 501, the broken tea residues will be sucked away by the vacuum cleaner 505 through the dust suction hood 504 and the dust suction pipe to ensure the quality of the product.
