Description

Technical Field

[0001] The invention relates to the technical field of tea dust removal, and in particular to a tea leaf picking and dust removal device. Background Art

[0002] Tea is a traditional Chinese drink that can be used to maintain health and prevent diseases. It is very popular among consumers. The general tea processing technology includes fresh leaf processing, withering, killing, rolling, chopping, fermentation, drying, frying and other processes. At present, after the tea leaves are picked, there are certain impurities such as dust and sand on the leaves. Therefore, when the tea leaves are further processed, they need to be cleaned to remove foreign matter such as dust, sand and stones adhering to the surface.

[0003] In order to solve the above problems, a cleaning box for cleaning tea leaves has appeared on the market; a screening plate, fan blades, and a stirring device are provided in the cleaning box. When the device is in use, air with a certain flow rate is introduced into the cleaning box under the action of the fan blades, so that the airflow can remove foreign matter such as dust, sand, and stones adhering to the tea leaves. The dust, sand, and other foreign matter adhering to the tea leaves are further dispersed by the stirring device. During the operation of the fan blades and the stirring device, impurities such as dust, sand, and stones will fall through the screening plate, thereby separating foreign matter such as dust, sand, and stones from the tea leaves. That is, the screening effect of the tea leaves is enhanced, and the screening efficiency of the tea leaves is improved.

[0004] The above-mentioned device has the following problems during actual use: when the screening plate is screening dust, sand and other foreign matters, due to the certain stickiness of dust, sand and other foreign matters, some of the dust, sand and other foreign matters will adhere to the screening holes of the screening plate. As the impurity removal process continues, the amount of dust, sand and other foreign matters adhering to the screening holes will gradually increase and accumulate into clumps. When dust, sand and other foreign matters accumulate into clumps, the aperture of the screening holes will be reduced, thereby weakening the screening effect and reducing the screening efficiency. In addition, if the dust, sand and other foreign matters accumulated in the screening holes are not cleaned for a long time, the screening holes will be blocked, which will lead to a decrease in the screening quality of the screening plate. Summary of the invention

[0005] The invention provides a tea leaf picking and impurity removing device, so as to solve the problem that the existing impurity removing device cannot clean the screening holes of the screening plate.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a tea picking and impurity removal device, comprising a dust removal cylinder with a feed inlet and a discharge outlet, and also comprising a dust removal mechanism arranged in the dust removal cylinder; the dust removal mechanism comprises a rotating shaft, a dust removal plate, a columnar block, a plurality of dust removal components equidistantly arranged along the circumferential direction of the rotating shaft, and a driving part for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the dust removal cylinder; the dust removal plate and the columnar block are both fixed to the rotating shaft; the dust removal component comprises a ventilation box, a plurality of dust removal parts equidistantly arranged along the length direction of the ventilation box, a power part for driving the ventilation box to do vertical reciprocating, and an air induction part for introducing air into the ventilation box; the ventilation box is slidably connected to the columnar block, and the ventilation box is located below the dust removal plate; the dust removal part comprises a ventilation pipe, ventilation holes equidistantly arranged on the ventilation pipe along the axial direction of the ventilation pipe, and dust removal holes on the dust removal plate; the ventilation pipe is connected to the ventilation box, and the ventilation pipe is communicated with the ventilation box, and the ventilation pipe can slide in and out of the dust removal hole.

[0007] The principles and advantages of this solution are:

[0008] 1. Pile the tea leaves on the dust removal plate, and then rotate the shaft to drive the dust removal plate and the ventilation box to rotate synchronously. During the circumferential motion of the ventilation box, driven by the power unit, the ventilation box can also make vertical reciprocating motion. During the vertical reciprocating motion of the ventilation box, the ventilation pipe can slide in and out of the dust removal hole. During the vertical reciprocating motion of the ventilation pipe, the ventilation pipe can clean up foreign objects such as dust, sand and stones adhering to the dust removal hole, thereby reducing the amount of foreign objects such as dust, sand and stones adhering to the dust removal hole, ensuring that the dust removal hole can efficiently and comprehensively screen foreign objects such as dust, sand and stones. In addition, the ventilation pipe can also act on the tea leaves during the vertical reciprocating motion, so that the ventilation pipe can beat the dust, sand and stones adhering to the tea leaves, so that foreign objects such as dust, sand and stones can fall from the tea leaves, and finally fall to the bottom of the dust removal cylinder through the dust removal hole, which enhances the cleaning effect of the tea leaves and improves the cleaning efficiency of the tea leaves.

[0009] 2. During the vertical reciprocating motion of the ventilation pipe, the air will be discharged through the ventilation holes under the action of the air induction part. During the air discharge, the air has a certain force, and the air will act on the dust removal holes, causing the dust, sand and other foreign objects adhering to the dust removal holes to loosen, thereby weakening the force of the dust, sand and other foreign objects adhering to the dust removal holes, so that the dust, sand and other foreign objects can be cleaned more fully and comprehensively under the action of the ventilation pipe. At the same time, the air can also act on the tea leaves, causing the dust, sand and other foreign objects adhering to the tea leaves to loosen, and then the air can be cleaned more efficiently and completely with the cooperation of the ventilation pipe, further enhancing the cleaning effect of the ventilation pipe on sand, dust and other foreign objects.

[0010] Furthermore, the dust removal assembly also includes a worm and a moving part for driving the worm to rotate; the worm is rotatably connected to the outer wall of the top of the ventilation box; the ventilation pipe is rotatably connected to the ventilation box; a worm wheel and a brush layer are respectively fixed to the ventilation pipe; the worm wheel is meshed with the worm; the length of the brush layer is greater than the radius of the dust removal hole.

[0011] The meshing of the worm and the worm wheel enables the ventilation pipe to rotate. As the ventilation pipe can rotate, the air discharged from the ventilation hole has a certain centrifugal force, thereby expanding the exhaust range of the air, ensuring that the air can diffuse over a large range, and making the contact between the air and the tea leaves more sufficient and comprehensive. That is, the air has a higher efficiency in cleaning foreign matter such as dust, sand and stones adhering to the tea leaves, and the cleaning quality is better.

[0012] During the movement of the ventilation pipe, the bristle layer can act on the inner wall of the dust removal hole. Under the action of the bristle layer, the dust, sand and other foreign objects adhering to the dust removal hole can be further cleaned, thereby ensuring that the dust, sand and other foreign objects can be completely cleaned, that is, the screening effect of the dust removal hole is comprehensively enhanced and the screening efficiency of the dust removal hole is improved.

[0013] Since the bristle layer can also rotate under the action of the ventilation duct, the bristle layer can further clean the dust, sand and other foreign objects adhering to the tea leaves during the contact between the bristle layer and the tea leaves, so that the force of the dust, sand and other foreign objects adhering to the tea leaves is further weakened, thereby ensuring that the dust, sand and other foreign objects can be completely separated from the tea leaves, thereby improving the cleaning efficiency of the tea leaves.

[0014] Furthermore, the air induction part includes a piston cylinder, a piston block, and a motion unit for driving the piston block to perform vertical reciprocating motion; the piston cylinder is fixedly connected to the outer wall of the ventilation box; the piston block is vertically slidably connected to the piston cylinder; the piston cylinder is respectively connected to an air outlet pipe and an air inlet pipe; the free end of the air outlet pipe is connected to the ventilation box.

[0015] Through the cooperation between the piston block and the piston cylinder, the air discharged into the ventilation box has a certain force, and when the air is discharged from the ventilation hole, the force of foreign matter such as dust, sand and stones adhering to the dust removal hole and tea leaves can be weakened, ensuring that foreign matter such as dust, sand and stones can be completely cleaned from the dust removal hole and tea leaves.

[0016] Furthermore, it also includes a linkage part arranged in the ventilation box; the linkage part includes a guide block, a moving tube, a hose, a plurality of air guide holes equidistantly opened on the top of the moving tube along the length direction of the moving tube, and a power unit for driving the moving tube to reciprocate along the length direction of the ventilation box; the guide block is fixedly connected to the ventilation box; the moving tube is slidably connected to the guide block; and both ends of the hose are respectively connected to the air outlet pipe and the moving tube.

[0017] By moving the tube back and forth along the length of the ventilation box, the air pressurized by the piston cylinder can be diffused in the ventilation box, thereby expanding the distribution range of the pressurized air in the ventilation box, further enhancing the flow effect of the air in the ventilation box, and ensuring that the air can be evenly discharged from several ventilation pipes.

[0018] Furthermore, the linkage part also includes a linkage unit; the linkage unit also includes a linkage block and a linkage hole opened on the moving tube; one end of the linkage block is fixedly connected to the inner wall of the ventilation box, and the other end of the linkage block is slidably connected to the linkage hole; the linkage block is attached to the top of the inner wall of the moving tube, and the air guide hole is located on the movement trajectory of the linkage block.

[0019] During the reciprocating motion of the moving tube, the amount of air discharged from the air guide hole can be adjusted under the action of the linkage block. When the amount of air discharged from the air guide hole is reduced, the pressure in the moving tube can be increased, so that when the air is discharged from the air guide hole, the flow speed is faster and the effective distance is longer, ensuring the air's cleaning effect on foreign matter such as dust, sand and stones adhering to the dust removal hole and tea leaves.

[0020] Furthermore, it also includes an auxiliary part arranged in the ventilation box; the auxiliary part includes a screw, a guide rod, a lifting block, a plurality of auxiliary blocks equidistantly arranged along the length direction of the lifting block, and a moving part for driving the screw to rotate; the screw is rotatably connected to the inner wall of the ventilation box; the guide rod is fixedly connected to the inner wall of the ventilation box; the lifting block is threadedly connected to the screw, and the lifting block is slidably connected to the guide rod; the auxiliary block is fixedly connected to the lifting block, the ventilation pipe is located on the movement trajectory of the auxiliary block, and the auxiliary block can slide in and out of the ventilation pipe.

[0021] Through the vertical reciprocating motion of the auxiliary block, the diameter of the ventilation duct can be changed under the action of the auxiliary block; when the auxiliary block is extended into the ventilation duct, the pressure of the air entering the ventilation duct will be further increased, so that the force of the air is stronger when it is discharged, and the effect of cleaning foreign matter such as dust, sand and stones adhering to the dust removal holes and tea leaves is better, that is, the efficiency of air cleaning foreign matter such as dust, sand and stones is further improved.

[0022] Furthermore, it also includes a linkage member arranged in the ventilation pipe; the linkage member includes a guide cylinder, a long rod, a first spring, and a hollow tube; the guide cylinder is fixedly connected to the inner wall at the top of the ventilation pipe; the long rod is vertically slidably connected to the guide cylinder; the two ends of the first spring are respectively connected to the guide cylinder and the guide rod; the outer wall of the hollow tube is in contact with the inner wall of the ventilation pipe, the top of the hollow tube is fixedly connected to the first side block, and the bottom of the hollow tube is fixedly connected to the second side block; the first side block is fixedly connected to the guide rod; the second side block is located on the movement trajectory of the auxiliary block; the ventilation hole is located on the movement trajectory of the hollow tube.

[0023] During the vertical reciprocating motion of the auxiliary block, the hollow tube will perform vertical reciprocating motion under the cooperation of the auxiliary block and the first spring. During the vertical reciprocating motion of the hollow tube, the amount of air outflow from some ventilation holes can be reduced, thereby increasing the pressure in the ventilation tube, so that when the air is discharged from the ventilation holes, the air has a stronger force and a wider range of action. That is, through the above-mentioned motion, the efficiency of air cleaning foreign matter such as dust, sand and stones adhering to the dust removal holes and tea leaves can be further improved.

[0024] Furthermore, it also includes a plurality of wind-driving blades which are equidistantly arranged along the circumferential direction of the screw rod; the wind-driving blades are fixedly connected to the screw rod.

[0025] During the rotation of the wind-driving blades, the air can be urged to move toward the location of the ventilation pipe, increasing the flow rate of air flowing into the ventilation pipe. In addition, the wind-driving blades can accelerate the flow rate of the air, further making the air move farther and diffuse more widely when discharged.

[0026] At the same time, during the rotation of the wind-expelling blades, the wind-expelling blades can disperse the air flowing out of the air guide holes, thereby further expanding the distribution range of the air pressurized by the piston cylinder in the moving pipe, and enabling the air to flow into the ventilation pipe more evenly.

[0027] Furthermore, the moving part includes a first gear and a first rack; the first gear is fixedly connected to the worm; the first rack is fixedly connected to the dust removal plate; and the first gear is meshed with the first rack.

[0028] During the vertical reciprocating motion of the worm, the first gear moves synchronously. During the vertical reciprocating motion of the first gear, since the first gear meshes with the first rack, the first gear drives the worm to rotate. Therefore, while the worm reciprocates vertically, the worm can also rotate.

[0029] Furthermore, the motion unit comprises a cam and a second spring; the cam is fixedly connected to the worm, and the cam abuts against the piston block; and two ends of the second spring are respectively connected to the piston cylinder and the piston block.

[0030] During the rotation of the worm, the cam rotates synchronously. During the rotation of the cam, when the raised portion of the cam abuts against the piston block, the piston block moves vertically downward, and the second spring is compressed; when the raised portion of the cam no longer abuts against the piston block, the piston block is reset under the action of the second spring, and the piston block moves vertically upward. Therefore, the piston block can perform vertical reciprocating motion. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Specific implementation process:

[0058] The picked tea leaves are piled up on the dust removal plate 3 along the feed port until the tea leaves are placed. Start the motor 10, and drive the rotating shaft 2 to rotate through the output shaft of the motor 10. During the rotation of the rotating shaft 2, the columnar block 4, the ventilation box 5, and the dust removal plate 3 all rotate synchronously. During the circumferential motion of the ventilation box 5, start the cylinder 11 again, and drive the hollow disk 38 to perform vertical reciprocating motion through the output shaft of the cylinder 11. During the vertical reciprocating motion of the hollow disk 38, the air disk cooperates with the third spring 39 to drive the slider 6 to perform vertical reciprocating motion. During the vertical reciprocating motion of the slider 6, the ventilation box 5 moves synchronously. Therefore, while the ventilation box 5 performs circumferential motion, the ventilation box 5 can also perform vertical reciprocating motion.

[0059] During the vertical reciprocating motion of the ventilation box 5, the ventilation pipe 7 moves synchronously. During the motion of the ventilation pipe 7, the ventilation pipe 7 can slide in and out of the dust removal hole 9, so that the ventilation pipe 7 can clean the dust, sand and other foreign objects adhering to the dust removal hole 9, thereby reducing the amount of dust, sand and other foreign objects adhering to the dust removal hole 9, ensuring that the dust removal hole 9 can efficiently and comprehensively screen the dust, sand and other foreign objects. In addition, the ventilation pipe 7 can also act on the tea leaves during the vertical reciprocating motion, so that the ventilation pipe 7 can beat the dust, sand and other foreign objects adhering to the tea leaves, so that the dust, sand and other foreign objects can fall from the tea leaves, and finally fall to the bottom of the dust removal cylinder 1 through the dust removal hole 9, that is, the cleaning effect of the tea leaves is enhanced and the cleaning efficiency of the tea leaves is improved.

[0060] During the vertical reciprocating motion of the ventilation box 5, the worm 12 moves synchronously. During the vertical reciprocating motion of the worm 12, the first gear 30 moves synchronously. During the vertical reciprocating motion of the first gear 30, since the first gear 30 is meshed with the first rack 31, the first gear 30 drives the worm 12 to rotate. Therefore, while the worm 12 reciprocates vertically, it can also rotate. During the rotation of the worm 12, the cam 32 rotates synchronously. During the rotation of the cam 32, when the raised portion of the cam 32 abuts against the piston block 16, the piston block 16 moves vertically downward, and the second spring 33 is compressed; when the raised portion of the cam 32 no longer abuts against the piston block 16, the piston block 16 is reset under the action of the second spring 33, and the piston block 16 moves vertically upward. Therefore, the piston block 16 can reciprocate vertically.

[0061] The piston block 16 and the piston cylinder 15 cooperate with each other, so that the air is discharged into the ventilation box 5 with a certain force. When the air flows in the ventilation box 5, the air will be discharged through the ventilation hole 8 and act on the dust removal hole 9, causing the dust, sand and other foreign objects adhering to the dust removal hole 9 to loosen, thereby weakening the force of the dust, sand and other foreign objects adhering to the dust removal hole 9, so that the dust, sand and other foreign objects can be cleaned more fully and comprehensively under the action of the ventilation pipe 7. At the same time, the air can also act on the tea leaves, causing the dust, sand and other foreign objects adhering to the tea leaves to loosen, and then the air can be cleaned more efficiently and completely under the cooperation with the ventilation pipe 7, further enhancing the cleaning effect of the ventilation pipe 7 on foreign objects such as sand and dust.

[0062] During the rotation of the worm 12, the meshing of the worm 12 and the worm wheel 13 enables the ventilation pipe 7 to rotate. Since the ventilation pipe 7 can rotate, the air discharged from the ventilation hole 8 has a certain centrifugal force, thereby expanding the discharge range of the air, ensuring that the air can be diffused over a large range, and making the contact between the air and the tea leaves more sufficient and comprehensive. That is, the air has a higher efficiency in cleaning foreign matter such as dust, sand and stones adhering to the tea leaves, and the cleaning quality is better.

[0063] During the movement of the ventilation pipe 7, the bristle layer 14 can act on the inner wall of the dust removal hole 9. Under the action of the bristle layer 14, foreign matter such as dust, sand and stones adhering to the dust removal hole 9 can be further cleaned, thereby ensuring that foreign matter such as dust, sand and stones can be completely cleaned, that is, the screening effect of the dust removal hole 9 is comprehensively enhanced, and the screening efficiency of the dust removal hole 9 is improved.

[0064] Since the bristle layer 14 can also rotate under the action of the ventilation pipe 7, during the period when the bristle layer 14 is in contact with the tea leaves, the bristle layer 14 can further clean the dust, sand and other foreign objects adhering to the tea leaves, so that the force of the dust, sand and other foreign objects adhering to the tea leaves is weakened again, which ensures that the dust, sand and other foreign objects can be completely separated from the tea leaves, thereby improving the cleaning efficiency of the tea leaves.

[0065] During the rotation of the ventilation pipe 7, the third gear 36 rotates synchronously. During the rotation of the third gear 36, the third gear 36 is meshed with the fourth gear 37, thereby driving the screw 22 to rotate. During the rotation of the screw 22, the second gear 34 rotates synchronously. During the rotation of the second gear 34, the second gear 34 is meshed with the second rack 35, thereby driving the moving pipe 18 to reciprocate along the length direction of the ventilation box 5.

[0066] By moving the tube 18 back and forth along the length direction of the ventilation box 5, the air pressurized by the piston cylinder 15 can be diffused in the ventilation box 5, thereby expanding the distribution range of the pressurized air in the ventilation box 5, further enhancing the flow effect of the air in the ventilation box 5, and ensuring that the air can be evenly discharged from a number of ventilation pipes 7.

[0067] During the reciprocating motion of the moving tube 18, the amount of air discharged from the air guide hole 20 can be adjusted under the action of the linkage block 21. When the amount of air discharged from the air guide hole 20 is reduced, the pressure in the moving tube 18 can be increased, so that when the air is discharged from the air guide hole 20, the flow speed is faster and the effective distance is farther, ensuring the air cleaning effect on foreign matter such as dust, sand and stones adhering to the dust removal hole 9 and tea leaves.

[0068] During the forward and reverse rotation of the screw rod 22, the lifting block 24 can reciprocate along the length direction of the guide rod 23. During the movement of the lifting block 24, the auxiliary block 25 moves synchronously. Through the vertical reciprocating motion of the auxiliary block 25, the diameter of the ventilation pipe 7 can be changed under the action of the auxiliary block 25; when the auxiliary block 25 is inserted into the ventilation pipe 7, the pressure of the air entering the ventilation pipe 7 will be further increased, so that the force of the air when discharged is stronger, and the dust, sand and other foreign matter adhering to the dust removal hole 9 and the tea leaves are better cleaned, that is, the efficiency of air cleaning dust, sand and other foreign matter is further improved.

[0069] During the vertical reciprocating motion of the auxiliary block 25, when the auxiliary block 25 abuts against the second side block, the second side block drives the hollow tube 28 to move vertically upward, and the first spring is compressed; when the auxiliary block 25 no longer abuts against the second side block, the hollow tube 28 is reset under the action of the first spring, and the hollow tube 28 moves vertically downward. Therefore, the hollow tube 28 can perform vertical reciprocating motion.

[0070] During the vertical reciprocating motion of the hollow tube 28, the amount of air discharged from a part of the ventilation holes 8 can be reduced, thereby increasing the pressure in the ventilation pipe 7, so that the air has a stronger force and a wider range of action when it is discharged from the ventilation holes 8. That is, through the above motion, the efficiency of air in cleaning dust, sand and other foreign matter adhering to the dust removal holes 9 and tea leaves can be further improved.

[0071] During the rotation of the screw 22, the air-driving blade 29 rotates synchronously. During the rotation of the air-driving blade 29, the air can be urged to move toward the location of the ventilation pipe 7, increasing the flow rate of air flowing into the ventilation pipe 7. In addition, the air-driving blade 29 can accelerate the flow speed of the air, further allowing the air to move farther and diffuse more widely when discharged.

[0072] At the same time, while the wind-expelling blades 29 are rotating, the wind-expelling blades 29 can disperse the air flowing out of the air guide holes 20, thereby further expanding the distribution range of the air pressurized by the piston cylinder 15 in the moving tube 18, and enabling the air to flow into the ventilation pipe 7 more evenly.

[0073] In summary, by cleaning the dust removal holes 9 through the ventilation pipe 7 and beating the tea leaves, foreign objects such as dust, sand and stones adhering to the tea leaves and the dust removal holes 9 can be efficiently cleaned, so that the dust, sand and stones finally fall to the bottom of the dust removal cylinder 1. At the same time, during the movement of the ventilation pipe 7, the air flowing in the ventilation box 5 and the ventilation pipe 7 is pressurized multiple times, ensuring the cleaning effect of the air on foreign objects such as dust, sand and stones adhering to the dust removal holes 9 and the tea leaves, and improving the cleaning efficiency and quality of the dust removal holes 9 and the tea leaves.
