[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The tea conveying device and method for tea production described in the present invention guides the hot air transmitted in the second ventilation groove through the provided first guide plate, so that a part of the hot air is discharged from the first air outlet below. As the hot air enters, the hot air is discharged from the plurality of first air outlets. While the toggle plate stirs the tea leaves, the hot air is in better contact with the tea leaves. The hot air passing through the second ventilation groove enters the third ventilation groove, and is discharged from the plurality of second air outlets through the provided second guide plate. The hot air is prevented from floating upward too quickly by being wrapped by the air gathering plate and the toggle plate, so that the contact time between the hot air and the tea leaves is longer. When the tea leaves are picked up and slide to the angle between the air gathering plate and the toggle plate, they can be dried on both sides at the same time, so that the drying effect is higher and more uniform.

[0021] 2. The conveying device and conveying method for tea production described in the present invention can screen the tea leaves through the provided sieve plate, so that tea leaves that are too small can pass through the sieve plate and fall into the collecting box.

[0022] 3. The tea production conveying device and the tea conveying method described in the present invention block the space between the two guide plates by setting a block that moves up and down, thereby facilitating the quantitative entry of tea leaves into the conveying box and avoiding the situation where too much tea leaves are put in at one time and affecting the drying effect. When the block is pressed against the bottom of the two guide plates, the hot air floating upward can be blocked to prevent the hot air from being discharged from the conveying box too quickly. The density of the pressurized hot air is increased, and the contact with the tea leaves is closer, thus shortening the drying time of the tea leaves. By shortening the drying time, the exposure time of the aroma components in the tea leaves to the high temperature environment is also shortened accordingly. In combination with the intermittent sealing of the conveying box, the aroma of the tea leaves can be prevented from dissipating too quickly, and the original aroma of the tea leaves can be better preserved while the tea leaves are being dried.

[0023] 4. The conveying device and conveying method for tea production described in the present invention can guide the upward floating hot air through the arranged air collecting plate, so that the hot air floats to the angle between the guide plate and the air collecting plate, and continues to flow along the first ventilation groove. The hot air flowing upward is guided by the guide plate to blow downward, which is convenient for drying the tea leaves between two adjacent toggling plates, thereby making the hot air use more efficient.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 12 As shown, the present invention provides a technical solution, a conveying device for tea production, including a conveyor 1, a conveying box 2 is arranged on the top of the conveyor 1, two support plates 3 are symmetrically fixedly connected to the bottom of the conveying box 2, two guide plates 4 are symmetrically fixedly connected to the top of the conveying box 2, the two guide plates 4 are both arranged in an arc shape, two side plates 5 are symmetrically fixedly connected to the two sides of the guide plate 4, the two side plates 5 are both fixedly connected to the conveying box 2, a feeding unit is arranged at the bottom of the conveying box 2, a mounting plate 42 is fixedly connected to one side of the conveying box 2, a motor 43 is fixedly connected to the top of the mounting plate 42, and the output end of the motor 43 extends to the conveying An air delivery pipe 6 is fixedly connected to the inside of the delivery box 2, an air pump 7 is fixedly connected to the other side of the delivery box 2, an output end of the air pump 7 is fixedly connected to an air intake pipe 8, a collar 9 is fixedly connected to the top of the air intake pipe 8, a cavity 10 is formed inside the collar 9, one end of the air delivery pipe 6 extends to the inside of the cavity 10 and is rotatably connected to the collar 9, a plurality of air intake grooves 11 are equidistantly formed on the outer wall of the air delivery pipe 6, the air intake grooves 11 are located inside the cavity 10, a heating wire 47 is provided on the inner wall of the air intake pipe 8, a plurality of air outlet grooves 12 are equidistantly formed on the outer wall of the air delivery pipe 6, the air outlet grooves 12 are located inside the delivery box 2.

[0040] Through the above technical scheme, the conveying box 2 is conveyed by the conveyor 1, and the tea leaves are placed between the two guide plates 4 so that the tea leaves fall into the conveying box 2. The bottom of the conveying box 2 is sealed by the provided unloading unit to prevent the tea leaves from falling. The air pump 7 and the heating wire 47 are started to draw air into the cavity 10 along the air intake pipe 8. The air is heated when passing through the heating wire 47. The hot air of the air intake cavity 10 enters the air delivery pipe 6 along the several air intake grooves 11 and is transmitted along the air delivery pipe 6 and is discharged when passing through the several air outlet grooves 12. Thus, hot air is introduced into the conveying box 2, and the inserts in the conveying box 2 are dried to prevent the tea leaves from sticking to each other and breeding microorganisms.

[0041] Specifically, a plurality of toggle plates 13 are equidistantly fixedly connected to the outer wall of the gas pipeline 6, a second ventilation groove 48 is provided on the inner wall of the toggle plate 13, the second ventilation groove 48 is communicated with the air outlet groove 12, a plurality of first air outlets 14 are equidistantly provided on both sides of the toggle plate 13, the first air outlet 14 is communicated with the second ventilation groove 48, two first guide plates 15 are symmetrically fixedly connected to the inner wall of the second ventilation groove 48 and located on the top of the first air outlet 14, and the first guide plates 15 are installed at an angle.

[0042] Through the above technical solution, the motor 43 is started to drive the gas pipeline 6 to rotate, so that the several toggle plates 13 rotate, and the tea leaves in the conveying box 2 are stirred, so that the hot air can contact the tea leaves evenly, and some tea leaves are prevented from being over-dried. The hot air discharged from the air outlet groove 12 enters the several second ventilation grooves 48 and flows along the second ventilation grooves 48. When passing through the first guide plate 15, under the guiding effect of the first guide plate 15, a part of the hot air is discharged from the first air outlet 14 below. Therefore, as the hot air enters, the hot air is discharged from the several first air outlets 14, and the hot air is better in contact with the tea leaves while the toggle plate 13 stirs the tea leaves.

[0043] Specifically, the outer wall of the toggle plate 13 is symmetrically fixedly connected with two air gathering plates 16, and the two air gathering plates 16 are both arranged in an arc shape. The inner wall of the air gathering plate 16 is provided with a third ventilation groove 49, and the third ventilation groove 49 is communicated with the second ventilation groove 48. The outer wall of the air gathering plate 16 is equidistantly provided with a plurality of second air outlets 17, and the second air outlets 17 are communicated with the third ventilation groove 49. The inner wall of the third ventilation groove 49 and located at the bottom of the second air outlet 17 are symmetrically fixedly connected with two second guide plates 18.

[0044] Through the above technical scheme, the hot air passing through the second ventilation groove 48 enters the third ventilation groove 49 and flows along the third ventilation groove 49. When passing through the second guide plate 18, under the guiding effect of the second guide plate 18, a part of the hot air is discharged from the second air outlet 17 above. Therefore, as the hot air enters, the hot air is discharged from several second air outlets 17. The hot air is wrapped by the air gathering plate 16 and the toggle plate 13 to prevent the hot air from floating upward too quickly, so that the contact time between the hot air and the tea leaves is longer. When the tea leaves are pulled up and slide to the angle between the air gathering plate 16 and the toggle plate 13, they can be dried on both sides at the same time, so that the drying effect is higher and more uniform.

[0045] Specifically, the inner wall of the toggle plate 13 is slidably connected with an extension plate 20 , both sides of the extension plate 20 are configured as inclined surfaces, and the interior of the toggle plate 13 is fixedly connected with a first spring 19 , which is fixedly connected to the extension plate 20 .

[0046] Through the above technical solution, the first spring 19 is set to make the extension plate 20 press against the inner wall of the conveying box 2. When the toggle plate 13 rotates, the extension plate 20 always slides against the inner wall of the conveying box 2, thereby preventing the tea leaves from adhering to the inner wall of the conveying box 2 and preventing the tea leaves from being exposed to hot air.

[0047] Specifically, the unloading unit includes a unloading port 28, which is opened at the bottom of the conveying box 2. The inner wall of the unloading port 28 is slidably connected with a baffle 29. The interior of the conveying box 2 is fixedly connected with a third spring 30. One end of the third spring 30 is fixedly connected to the baffle 29. The elastic force of the third spring 30 is smaller than the elastic force of the first spring 19. The top of the baffle 29 is fixedly connected with a toggle block 32. A sealing groove 31 is opened inside the conveying box 2. The sealing groove 31 is communicated with the unloading port 28. The baffle 29 fits the inner wall of the sealing groove 31. The inner wall of the baffle 29 is equidistantly provided with a number of drainage grooves 33.

[0048] Through the above technical solution, the motor 43 is started to drive the gas pipeline 6 to rotate clockwise, so that the toggle plate 13 rotates clockwise, and drives the extension plate 20 to rotate clockwise. When the extension plate 20 rotates to the position of the toggle block 32, one side of the baffle plate 29 is pressed against the sealing groove 31, so that the baffle plate 29 cannot move. As the toggle plate 13 rotates, under the extrusion of the toggle block 32, the inclined surface of the side of the extension plate 20 is pressed, and the extension plate 20 is pushed to slide in the toggle plate 13, and the first spring 19 is pressed. When the extension plate 20 rotates to a position away from the toggle block 32, under the action of the first spring 19, the extension plate 20 is reset. Therefore, when the gas pipeline 6 rotates clockwise, the baffle plate 29 is always in contact with the sealing groove 31, so that the discharge port 28 is in a sealed state to prevent tea from falling, and a plurality of drainage grooves 33 are provided on the baffle plate 29 to discharge the water drained from the tea leaves. The motor 43 drives the gas pipeline 6 to rotate counterclockwise, so that the toggle plate 13 rotates counterclockwise, and drives the extension plate 20 to rotate counterclockwise. When the extension plate 20 rotates to the position of the toggle block 32, the toggle block 32 is pushed to move, so that the baffle plate 29 slides in the discharge port 28, and the third spring 30 is pressed. At this time, the discharge port 28 is opened, and the tea leaves can fall from the discharge port 28. When the third spring 30 is compressed to the limit, as the toggle plate 13 rotates and under the pressure of the toggle block 32, it presses against the inclined surface of the side of the extension plate 20, pushes the extension plate 20 to slide in the toggle plate 13, and presses the first spring 19. When the extension plate 20 rotates to a position where it is separated from the toggle block 32, under the action of the first spring 19, the extension plate 20 is reset again. Thus, when the gas pipeline 6 rotates counterclockwise, the discharge port 28 can be intermittently opened, which is convenient for gradually removing the tea leaves in the conveying box 2.

[0049] Specifically, two groups of fixed shafts 21 are symmetrically fixedly connected inside the conveying box 2, and the outer walls of the two groups of fixed shafts 21 are slidably connected with connecting plates 22. One side of two adjacent connecting plates 22 is fixedly connected with a slide plate 27, and a sieve plate 24 is fixedly connected between two adjacent slide plates 27. The sieve plate 24 and the slide plate 27 are both slidably connected to the conveying box 2. The outer wall of the fixed shaft 21 is sleeved with a second spring 23, the bottom of the second spring 23 is fixedly connected to the conveying box 2, and the top of the second spring 23 is fixedly connected to the connecting plate 22. The elastic force of the second spring 23 is less than the elastic force of the first spring 19, and the outer wall of the sieve plate 24 is fixedly connected with a protrusion 25, and both sides of the protrusion 25 are set as inclined surfaces. The bottom of the conveying box 2 is symmetrically slidably connected with two aggregate boxes 26.

[0050] Through the above technical scheme, the tea leaves can be screened by the set sieve plate 24, so that tea leaves with too small a size can pass through the sieve plate 24 and fall into the collecting box 26. When the toggle plate 13 rotates, the extension plate 20 is driven to rotate. When the extension plate 20 rotates to the position of the protrusion 25, it presses against the inclined surface of the side of the protrusion 25, pushes the protrusion 25 to slide downward, drives the sieve plate 24 to move downward, and compresses the second spring 23. When the extension plate 20 rotates to a position disengaged from the protrusion 25, the sieve plate 24 is reset under the action of the second spring 23. As a result, as the toggle plate 13 rotates, the sieve plate 24 can be driven to vibrate intermittently, thereby preventing the sieve plate 24 from being blocked by tea leaves and affecting the screening effect.

[0051] Specifically, a first ventilation groove 35 is provided inside the two guide plates 4, and an air collecting plate 36 is fixedly connected to the inner walls of the two guide plates 4. The two air collecting plates 36 are installed at an angle, and an air inlet 34 is provided on the inner wall at the angle between the guide plate 4 and the air collecting plate 36. The air inlet 34 is communicated with the first ventilation groove 35.

[0052] Through the above technical solution, the hot air blown out from the first air outlet 14 and the second air outlet 17 floats upward, and when it contacts the air collecting plate 36, it flows upward along the inclined surface of the air collecting plate 36, and when it passes through the angle between the guide plate 4 and the air collecting plate 36, it enters the first ventilation groove 35 along the air inlet 34, and continues to flow along the first ventilation groove 35. Guided by the guide plate 4, the hot air flowing upward is blown downward, which is convenient for drying the tea leaves between the two adjacent toggle plates 13, thereby making the use of hot air more efficient.

[0053] Specifically, the inner walls of the two side plates 5 are slidably connected with a fixed plate 38, a stopper 37 is fixedly connected between the two fixed plates 38, the top of the stopper 37 is set as a symmetrical inclined surface, and the two inclined surfaces at the top of the stopper 37 respectively fit the bottom of the two guide plates 4, and the bottom of the fixed plate 38 is fixedly connected with a fourth spring 39, the fourth spring 39 is fixedly connected to the side plate 5, and the outer wall of the side plate 5 is provided with a linkage assembly.

[0054] By the above technical scheme, the motor 43 drives the fixed plate 38 to move downward intermittently through the linkage assembly while the motor 43 rotates. When the fixed plate 38 moves downward, the stopper 37 is driven to move downward, so that the stopper 37 is separated from the two guide plates 4. After the stopper 37 is lost, it is convenient to pass the tea leaves from between the two guide plates 4 into the conveying box 2. When the fixed plate 38 moves upward and resets, the stopper 37 is driven to press against the bottom of the two guide plates 4 to block the space between the two guide plates 4, thereby facilitating the quantitative entry of the tea leaves into the conveying box 2, avoiding the one-time delivery of too much tea leaves to affect the drying effect, and when the stopper 37 presses against the bottom of the two guide plates 4, it can block the hot air floating upward to prevent the hot air from being discharged from the conveying box 2 quickly. The density of the pressurized hot air increases, and the contact with the tea leaves is closer, shortening the drying time of the tea leaves. By shortening the drying time, the exposure time of the aroma components in the tea leaves to the high temperature environment is also shortened accordingly, and the intermittent sealing of the conveying box 2 is coordinated to prevent the aroma of the tea leaves from dissipating too quickly, and the original aroma of the tea leaves is better retained while the tea leaves are dried.

[0055] Specifically, the linkage assembly includes a rotating shaft 40, which is rotatably connected to the side plate 5 and is located above the fixed plate 38. The outer wall of the rotating shaft 40 is fixedly connected with a cam 41, the outer wall of the output end of the motor 43 is fixedly connected with a second pulley 45, one end of the rotating shaft 40 is fixedly connected with a first pulley 44, and the first pulley 44 and the second pulley 45 are connected through a transmission belt 46.

[0056] Through the above technical solution, the motor 43 starts and drives the second pulley 45 to rotate. Through the set transmission belt 46, the first pulley 44 is driven to rotate, the rotating shaft 40 is rotated, and the cam 41 is driven to rotate. When the raised end of the cam 41 rotates to the bottom, the fixed plate 38 is pushed to move downward, so that the stopper 37 moves downward. While the fixed plate 38 moves downward, the fourth spring 39 is pressed. When the raised end of the cam 41 rotates to the top, the squeezing of the cam 41 is lost. Under the action of the fourth spring 39, the fixed plate 38 is pushed to move upward and reset, driving the stopper 37 to move upward and reset.

[0057] A conveying method for a conveying device for tea production, the conveying method is applicable to the above-mentioned conveying device for tea production, and the steps of the conveying method are as follows:

[0058] S1: Use the conveyor 1 to convey the conveying box 2, put the tea leaves between the two guide plates 4, let the tea leaves fall into the conveying box 2, start the air pump 7 and the heating wire 47, and let hot air into the conveying box 2 to dry the tea leaves;

[0059] S2: Start the motor 43 to drive the gas pipeline 6 to rotate clockwise, so that the plurality of toggle plates 13 rotate to stir the tea leaves in the conveying box 2, and control the cam 41 to rotate so that the block 37 moves up and down reciprocatingly to intermittently close the space between the two guide plates 4;

[0060] S3: When the tea leaves need to be taken out, the motor 43 is started to drive the gas pipeline 6 to rotate counterclockwise, so that the discharge port 28 is intermittently opened, and the tea leaves in the conveying box 2 are gradually taken out.

[0061] When in use, the conveying box 2 is conveyed by the conveyor 1, and the tea leaves are placed between the two guide plates 4. The motor 43 is started to drive the second pulley 45 to rotate, and the first pulley 44 is driven to rotate through the provided transmission belt 46, so that the rotating shaft 40 rotates, and the cam 41 is driven to rotate. When the raised end of the cam 41 rotates to the bottom, the fixed plate 38 is pushed to move downward, so that the stopper 37 moves downward. When the fixed plate 38 moves downward, the fourth spring 39 is pressed. When the raised end of the cam 41 rotates to the top, the squeezing of the cam 41 is lost. Under the action of the fourth spring 39, the fixed plate 38 is pushed to move upward and reset, driving the stopper 37 to move upward and reset. When the stopper 37 moves downward, it separates from the two guide plates 4, and the stopper 37 is lost. After being blocked, it is convenient for the tea leaves to enter the conveying box 2 from between the two guide plates 4. When the stopper 37 moves upward and resets, it presses against the bottom of the two guide plates 4 to block the space between the two guide plates 4, thereby making it convenient for the tea leaves to enter the conveying box 2 in a quantitative manner, avoiding the situation where too much tea leaves are put in at one time and affecting the drying effect. When the stopper 37 presses against the bottom of the two guide plates 4, it can block the hot air floating upward and prevent the hot air from being discharged from the conveying box 2 too quickly. The density of the pressurized hot air increases, and the contact with the tea leaves is closer, thus shortening the drying time of the tea leaves. By shortening the drying time, the exposure time of the aroma components in the tea leaves to the high temperature environment is also shortened accordingly, and the intermittent sealing of the conveying box 2 is combined to prevent the aroma of the tea leaves from wafting away too quickly. At the same time, in order to better preserve its original aroma, the air pump 7 and the heating wire 47 are started, and the air is drawn into the cavity 10 along the air inlet pipe 8. The air is heated when passing through the heating wire 47, and the hot air from the air inlet cavity 10 enters the air delivery pipe 6 along the plurality of air inlet slots 11, and is transmitted along the air delivery pipe 6, and is discharged after passing through the plurality of air outlet slots 12. When the motor 43 is started, the air delivery pipe 6 is driven to rotate, so that the plurality of toggle plates 13 are rotated to stir the tea leaves in the conveying box 2, so that the hot air can contact the tea leaves evenly, and some tea leaves are prevented from being over-dried. The first spring 19 is provided to make the extension plate 20 press against the inner wall of the conveying box 2, and when the toggle plate 13 rotates, the extension plate 20 always slides against the inner wall of the conveying box 2, thereby being able to It is enough to prevent the tea leaves from adhering to the inner wall of the conveying box 2 and prevent the tea leaves from being out of contact with the hot air. The hot air discharged from the air outlet groove 12 enters into the plurality of second air outlet grooves 48 and flows along the second air outlet grooves 48. When passing through the first guide plate 15, a part of the hot air is discharged from the first air outlet 14 below under the guiding effect of the first guide plate 15. Thus, with the entry of the hot air, the hot air is discharged from the plurality of first air outlets 14. While the toggle plate 13 stirs the tea leaves, the hot air is in better contact with the tea leaves. The hot air passing through the second air outlet grooves 48 enters into the third air outlet grooves 49 and flows along the third air outlet grooves 49. When passing through the second guide plate 18, a part of the hot air is discharged from the second air outlet 17 above under the guiding effect of the second guide plate 18.As a result, as the hot air enters, the hot air is discharged from the plurality of second air outlets 17, and is wrapped by the air gathering plate 16 and the toggle plate 13 to prevent the hot air from floating upward too quickly, so that the contact time between the hot air and the tea leaves is longer, and when the tea leaves that have been tossed up slide to the angle between the air gathering plate 16 and the toggle plate 13, they can be dried on both sides at the same time, so that the drying effect is higher and more uniform. When the motor 43 is started to control the gas pipeline 6 to rotate clockwise, the toggle plate 13 rotates clockwise, driving the extension plate 20 to rotate clockwise. When the extension plate 20 rotates to the position of the toggle block 32, one side of the baffle plate 29 presses against the sealing groove 31, so that the baffle plate 29 cannot move. As the toggle plate 13 rotates, the toggle block 32 presses against the inclined surface of the side of the extension plate 20. , pushing the extension plate 20 to slide in the toggle plate 13, compressing the first spring 19. When the extension plate 20 rotates to a position disengaged from the toggle block 32, the extension plate 20 is reset under the action of the first spring 19. As a result, when the gas pipeline 6 rotates clockwise, the baffle plate 29 always fits the sealing groove 31, so that the discharge port 28 is in a sealed state to prevent tea leaves from falling. In addition, a plurality of drainage grooves 33 are provided on the baffle plate 29 to discharge the water drained from the tea leaves. The tea leaves can be screened through the provided sieve plate 24, so that tea leaves with too small a size can pass through the sieve plate 24 and fall into the collecting box 26. When the toggle plate 13 rotates, the extension plate 20 is driven to rotate. When the extension plate 20 rotates to the position of the protrusion 25, the side of the protrusion 25 is pressed against the The inclined surface pushes the protrusion 25 to slide downward, driving the sieve plate 24 to move downward and compressing the second spring 23. When the extension plate 20 rotates to a position where it is disengaged from the protrusion 25, the sieve plate 24 is reset under the action of the second spring 23. As a result, as the toggle plate 13 rotates, the sieve plate 24 can be driven to vibrate intermittently to prevent the sieve plate 24 from being blocked by tea leaves and affecting the screening effect. The hot air blown out from the first air outlet 14 and the second air outlet 17 floats upward, and when it contacts the air collecting plate 36, it flows upward along the inclined surface of the air collecting plate 36. When passing through the angle between the guide plate 4 and the air collecting plate 36, it enters the first ventilation groove 35 along the air inlet 34 and continues to flow along the first ventilation groove 35. The hot air flowing upward is guided by the guide plate 4 to Blowing downward is convenient for drying the tea leaves between two adjacent toggle plates 13, thereby making the use of hot air more efficient. When it is necessary to take out the tea leaves, start the motor 43 to drive the gas pipeline 6 to rotate counterclockwise, so that the toggle plate 13 rotates counterclockwise, and drives the extension plate 20 to rotate counterclockwise. When the extension plate 20 rotates to the position of the toggle block 32, the toggle block 32 is pushed to move, so that the baffle plate 29 slides in the discharge port 28 and the third spring 30 is pressed. At this time, the discharge port 28 is opened, and the tea leaves can fall from the discharge port 28. When the third spring 30 is pressed to the limit, with the rotation of the toggle plate 13 and under the pressure of the toggle block 32, it presses against the inclined surface of the side of the extension plate 20, pushing the extension plate 20 to slide in the toggle plate 13 and pressing the first spring 19.When the extension plate 20 rotates to a position away from the toggle block 32, the first spring 19 causes the extension plate 20 to reset again, and thus, when the gas pipeline 6 rotates counterclockwise, the feed opening 28 can be opened intermittently, so as to facilitate the gradual removal of tea leaves in the conveying box 2.
