Description

Technical Field

[0001] The invention relates to the field of tea screening, and more particularly to a tea screening device used in tea planting. Background Art

[0002] The tea screening device is a device used to screen and grade tea leaves during the tea production process. After a long period of use, the internal parts of the screening device may overheat, which may easily cause machine failure.

[0003] In view of the above technical problems, the prior art has also proposed some solutions, such as (China invention patent with announcement number CN108636782B) discloses a tea screening device for tea planting, which realizes cooling and cooling of components in the device by setting a cooling structure; Although this device can extend the service life of the screening device, the following problems still exist during the screening process of tea leaves: since the texture of tea leaves themselves is relatively fragile, while the tea leaves are screened through frequent vibrations, the tea leaves will collide with each other. The violent vibration increases the speed at which the tea leaves collide with each other, increasing the possibility of tea leaves breaking. Especially when the shapes and sizes of the tea leaves are inconsistent, the tea leaves will move in different ways and speeds on the vibrating screen. The uneven movement causes irregular collisions between different tea leaves, making the tea leaves easily break during the screening process. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a tea screening device for tea planting.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) This scheme is provided with a softening and anti-breakage treatment part. When the tea leaves fall from the feed part onto the conveyor belt one, the atomizing humidifier at the upper end of the frame one can atomize and humidify the upper surface of the tea leaves on the conveyor belt one. When the tea leaves on the conveyor belt one pass through the inclined plate one and fall onto the conveyor belt two, the tea leaves are turned over. Then, the atomizing humidifier in the frame one atomizes and humidifies the upper surface of the turned tea leaves, so that the tea leaves can be evenly humidified. The softening and anti-breakage treatment part realizes the softening pretreatment of the tea leaves, softens the fiber tissue in the tea leaves, increases the toughness of the tea leaves, thereby reducing the breakage caused by vibration or collision during the screening process. At the same time, the amount of dust in the tea leaves after humidification will be significantly reduced, which not only helps to keep the working environment clean, but also reduces the dust content in the tea leaves and improves the quality of the tea leaves.

[0017] (2) This scheme is provided with a homogenizing and humidifying component. After the tea leaves pre-softened by the softening and anti-breakage treatment part enter the homogenizing and humidifying component, the atomizing nozzle can humidify and soften the tea leaves again. The tea leaves already have a certain degree of moisture when entering the hollow cylinder. When further humidified in the hollow cylinder, since the surface of the tea leaves has been moistened, the moisture is more easily evenly distributed and absorbed. The tea leaves are moved and rotated so that each piece of tea leaves can be exposed to moisture. On the one hand, the humidification effect can be made more uniform. On the other hand, it can avoid the tea leaves being subjected to greater friction or impact force due to dryness and fragility when the tea leaves are directly rotated for humidification and softening, thereby preventing the tea leaves from being broken.

[0018] (3) This scheme is provided with a material leveling component. When the motor three drives the belt body to move to transport the tea leaves, it can also drive the rod body two and the material-displacing rod two to rotate. The material-displacing rod two rotates to disperse the tea leaves accumulated on the belt body, thereby preventing the tea leaves accumulated too much from falling directly from the belt body onto the conveyor belt one, so that the tea leaves on the conveyor belt one are evenly dispersed, and the atomizing humidifier can more evenly humidify and soften the tea leaves on the conveyor belt one.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 10 A tea screening device for tea planting comprises a frame 1, a feeding part 6 fixed to the upper end of the frame 1, a screening component 3 inserted in the frame 1, and a storage oven 4 located on one side of the screening component 3 for storing screened tea leaves and drying the tea leaves. The frame 1 is internally connected with a softening and anti-crushing treatment part 2, and the softening and anti-crushing treatment part 2 includes a conveyor belt 1 21 and a conveyor belt 2 22 rotatably connected inside the frame 1, an inclined plate 1 23 located between the conveyor belt 1 21 and the conveyor belt 2 22, two motors 1 24 fixedly connected to one side of the outer surface of the frame 1, two atomizing humidifiers 25 fixedly connected to the upper end of the frame 1 and the inner wall of the frame 1, and a material guide plate 26 fixedly connected to the inner wall of the frame 1 and located below the conveyor belt 22; The atomizing humidifier 25 fixedly connected to the inner wall of the frame 1 is located above the conveyor belt 2 22 , and the output shafts of the two motors 24 both penetrate the frame 1 and are connected to the conveyor belt 1 21 and the conveyor belt 2 22 respectively.

[0023] The feeding part 6 includes a box body 61 fixedly connected to the upper end of the frame body 1, a material cavity 62 opened inside the box body 61, two roller bodies 65 rotatably connected to the inner wall of the material cavity 62, a belt body 63 sleeved on the outside of the two roller bodies 65, and a motor three 64 fixedly connected to one side of the outer surface of the box body 61, and the output shaft of the motor three 64 passes through the box body 61 and is fixedly connected to one side of one of the roller bodies 65.

[0024] The sub-screening assembly 3 includes a frame body 2 32 inserted into the frame body 1, two shock-absorbing pads 31 fixedly connected to both sides of the frame body 2 32, a screen mesh 1 33 and a screen mesh 2 35 fixedly connected to the inner wall of the frame body 2 32, a blanking plate 34 fixedly connected to the inner wall of the frame body 2 32 and located between the screen mesh 1 33 and the screen mesh 2 35, and a vibrating part 36 fixedly connected to the inner wall of the frame body 2 32 and located below the screen mesh 2 35. A blower 37 and a baffle plate 38 are also fixedly connected to the inner wall of the frame body 2 32, and the blower 37 is located between the screen mesh 1 33 and the blanking plate 34, and the baffle plate 38 is located on the left side of the blanking plate 34, and the baffle plate 38 is also located above the screen mesh 2 35, and the air outlet end of the blower 37 faces the baffle plate 38.

[0025] By adopting the above technical scheme, the tea leaves to be screened are placed in the box body 61, and the tea leaves are placed on the belt body 63. The motor 3 64 works to drive the roller body 65 to rotate, and the roller body 65 rotates to drive the belt body 63 to move, and the belt body 63 drives the tea leaves to move. The tea leaves fall from the belt body 63 and fall on the conveyor belt 21. The atomizing humidifier 25 on the frame 1 works to generate water mist, and the water mist is evenly sprayed on the upper surface of the tea leaves on the conveyor belt 21. The tea leaves fall from the conveyor belt 21 onto the inclined plate 23, and then fall from the inclined plate 23 onto the conveyor belt 22. The function of the inclined plate 23 is to turn over the tea leaves so that the tea leaves are humidified by the atomizing humidifier 25. One side faces downward, so that the atomizing humidifier 25 located above the conveyor belt 22 can atomize and humidify the side of the tea leaves that has not been softened by the spray, so as to achieve uniform humidification and softening of the upper and lower surfaces of the tea leaves, soften the fiber tissue in the tea leaves, increase the toughness of the tea leaves, thereby reducing the breakage caused by vibration or collision during the screening process, and at the same time, the amount of dust in the tea leaves after humidification will be significantly reduced, which not only helps to keep the working environment clean, but also reduces the dust content in the tea leaves and improves the quality of the tea leaves. The tea leaves after humidification and softening fall from the conveyor belt 22 onto the guide plate 26, and then fall onto the screen 33, and the vibration part 3 6 (the vibration unit composed of a vibration motor and other structures, which belongs to the mature existing technology and will not be described here) generates vibration to drive the screen 1 33, the drop plate 34 and the screen 2 35 to vibrate, and the tea leaves passing through the screen 1 33 fall toward the drop plate 34. In this process, due to the differences in the structure and composition of the tea leaves and the tea stems, their ability to absorb and retain moisture is also different. In this way, after the tea leaves are humidified, the weight changes of the tea leaves and the tea stems may be different, thereby increasing the difference in their weight. The weight of the stems is generally greater than the weight of the tea leaves, so the blower is used to humidify the tea leaves. 37 can blow air to the tea leaves falling from the screen 1 33, blow the lighter tea leaves onto the baffle plate 38, and fall from the baffle plate 38 to the screen 2 35, and the heavier leaf stems fall on the drop plate 34, so as to screen the tea leaves. In actual use, a collection box can be placed under the screen 2 35 to collect the small particles of tea debris passing through the screen 2 35. The materials on the screen 1 33, the drop plate 34 and the screen 2 35 flow toward the storage oven 4, which stores the screened materials separately (with partitions inside), and can also dry the humidified and softened tea leaves.

[0026] like Figure 6 As shown, a negative pressure fan 66 and an inclined plate 67 are fixedly connected to the inner wall of the material chamber 62, and the negative pressure fan 66 and the inclined plate 67 are both located below the belt body 63. A material storage box 68 is movably connected to the inner wall of the frame body 1, and the material storage box 68 is located below the inclined plate 67. The negative pressure suction end of the negative pressure fan 66 faces the inclined plate 67.

[0027] By adopting the above technical solution, the negative pressure fan 66 can generate a vacuum negative pressure. When the dried tea leaves fall from the belt body 63 to the conveyor belt 21, the debris in the tea leaves can be sucked away by the negative pressure fan 66, and the debris falls on the inclined plate 67, and then falls from the inclined plate 67 into the storage box 68, thereby realizing the preliminary screening of the debris in the tea leaves.

[0028] like Figure 2 - Figure 4 As shown, the inner wall of the frame 1 is also connected to a homogenizing and humidifying assembly 5, and the homogenizing and humidifying assembly 5 includes a hollow cylinder 51 sleeved on the outside of the guide plate 26, two connecting members 52 symmetrically fixed to the outer surface of the hollow cylinder 51, a bracket 53 fixed to one side of the hollow cylinder 51, a bracket 2 54 fixed to the inner wall of the hollow cylinder 51, a rod 1 55 rotatably connected between the bracket 1 53 and the bracket 2 54, a material shifting rod 1 58 fixed to the outer surface of the roller body 65, an extending claw 59 fixed to the outer surface of the material shifting rod 1 58, an atomizing nozzle 57 inserted into the inside of the hollow cylinder 51, and a motor 2 56 fixed to one side of the bracket 1 53, the other ends of the two connecting members 52 are fixed to the inner wall of the frame 1, and the output shaft of the motor 2 56 passes through the bracket 1 53 and is fixed to the rod 1 55.

[0029] By adopting the above technical scheme, the tea leaves dropped from the guide plate 26 enter the hollow cylinder 51, and the motor 2 56 drives the rod body 1 55 and the material-moving rod 1 58 to rotate. The rotation of the material-moving rod 1 58 and the extension claw 59 can drive the tea leaves in the hollow cylinder 51 to move, move the tea leaves and lift the tea leaves. The atomizing nozzle 57 can humidify and soften the tea leaves again. The tea leaves have a certain degree of moisture when entering the hollow cylinder 51. When further humidified in the hollow cylinder 51, since the surface of the tea leaves has been moistened, the moisture is more easily evenly distributed and absorbed. Moving the tea leaves to move and rotate the tea leaves can allow each piece of tea to come into contact with moisture. On the one hand, it can make the humidification effect more uniform. On the other hand, it can avoid the tea leaves being subjected to greater friction or impact force due to dryness and fragility when the tea leaves are directly rotated for humidification and softening, thereby avoiding the tea leaves from being broken.

[0030] like Figure 5 - Figure 7 As shown, the box body 61 is also connected to a material leveling assembly 7, and the material leveling assembly 7 includes a rod body 2 71 rotatably connected to the inner wall of the material chamber 62, a material moving rod 2 72 fixedly connected to the outer surface of the rod body 2 71, a pulley 1 73 located inside the box body 61 and fixedly sleeved on the outside of the output shaft of the motor 3 64, a pulley 2 74 rotatably connected to the box body 61 and one side of which is fixedly connected to one end of the rod body 2 71, and a synchronous belt 75 that drives the pulley 1 73 and the pulley 2 74.

[0031] By adopting the above technical scheme, when the motor three 64 works to drive the roller body 65 to rotate, it can also drive the pulley one 73 to rotate. The rotation of the pulley one 73 drives the pulley two 74 to rotate through the synchronous belt 75. The rotation of the pulley two 74 drives the material shifting rod two 72 to rotate. The material shifting rod two 72 rotates to shift the tea leaves accumulated on the belt body 63, so that the tea leaves accumulated on the belt body 63 are dispersed, and it is prevented that too much tea leaves accumulate directly from the belt body 63 onto the conveyor belt one 21, so that the tea leaves on the conveyor belt one 21 are evenly dispersed, so that the atomizing humidifier 25 can more evenly humidify and soften the tea leaves on the conveyor belt one 21.

[0032] like Figure 1 and Figure 8 As shown, it also includes an anti-sticking and material removal component 8 connected to the bracket 2 54, and the anti-sticking and material removal component 8 includes two top plates 81 symmetrically fixed to the upper end of the bracket 2 54, a motor 4 82 and a top seat 83 respectively fixed to the upper ends of the two top plates 81, a screw rod 84 with one end rotatably connected to one side of the top seat 83 and the other end fixed to the output shaft of the motor 4 82, a screw seat 85 screwed to the outside of the screw rod 84, a movable seat 86 fixed to the lower end of the screw seat 85, a seat body 87 connected to the inside of the movable seat 86, and a nozzle 871 fixed to the inside of the seat body 87, and the movable seat 86 is slidably connected to the inner wall of the bracket 2 54.

[0033] By adopting the above technical scheme, when the tea leaves after humidification and softening fall on the screen 33, the tea leaves may adhere to the screen 33 due to moisture. Therefore, an air jet 871 is designed to blow air toward the upper surface of the screen 33 through the air jet 871. On the one hand, it can realize the pre-drying treatment of the tea leaves, and on the other hand, it can blow the tea leaves adhered to the screen 33 to prevent the tea leaves from adhering to the screen 33. The motor 4 82 is used to drive the screw rod 84 to rotate. The rotation of the screw rod 84 can drive the screw seat 85 and the movable seat 86 to move, so as to adjust the position of the air jet 871, so that the air jet 871 can move and blow the tea leaves adhered to different areas of the screen 33.

[0034] like Fig. 9 and Fig.10 As shown, the movable seat 86 is provided with a movable groove 2 861 and a movable groove 3 862 connected to the movable groove 2 861, and the seat body 87 is rotatably connected in the movable groove 2 861, a rotary joint 88 is fixedly connected to the upper end of the movable seat 86, and the inner tube of the rotary joint 88 passes through the movable seat 86 and the seat body 87 and is connected to the input end of the nozzle 871 inside the seat body 87, and a movable block 863 is slidably connected in the movable groove 3 862.

[0035] The inner wall of the frame body 32 is symmetrically provided with two movable grooves 321, and the inner walls of the two movable grooves 321 are fixedly connected with side plates 89, and one side of the two side plates 89 is integrally formed with a flange 891 (by Fig. 9 It can be seen that the flanges 891 of the two side plates 89 are not symmetrically arranged, and the flanges 891 on the two side plates 89 are arranged alternately and staggered). Both ends of the movable block 863 are fixedly connected with a column 864, and a tooth key 1 865 is provided on one side of the movable block 863, and a tooth key 2 866 meshing with the tooth key 1 865 is provided on the outer surface of the seat body 87.

[0036] By adopting the above technical solution, when the movable seat 86 moves inside the frame body 2 32, the movable block 863 moves inside the movable seat 86, and the column 864 on one side of the movable block 863 will first contact the flange 891 on one side of the side plate 89, and the flange 891 on one side pushes the column 864 and the movable block 863 on one side to move toward the other side plate 89. Since the flanges 891 on the two side plates 89 are alternately staggered, when the column 864 on one side is separated from the flange 891 on one side, The flange 891 on the side plate 89 on the other side will contact the column 864 on the other side, pushing the movable block 863 to the other direction. While the movable seat 86 is driven by the screw 84, the movable block 863 reciprocates in the movable seat 86. While the movable block 863 reciprocates, it drives the seat body 87 and the air jet head 871 in the seat body 87 to rotate through the tooth key 865, thereby adjusting the blowing direction of the air jet head 871, and blowing the tea leaves adhered to the screen 33 from different directions to improve efficiency.

[0037] Usage: put the tea leaves to be screened into the box body 61, and put the tea leaves on the belt body 63. The motor 3 64 drives the roller body 65 to rotate, and the roller body 65 rotates to drive the belt body 63 to move. When the motor 3 64 drives the roller body 65 to rotate, it can also drive the pulley 1 73 to rotate. The rotation of the pulley 1 73 drives the pulley 2 74 to rotate through the synchronous belt 75. The rotation of the pulley 2 74 drives the material-dispensing rod 2 72 to rotate. The material-dispensing rod 2 72 rotates to dispense the tea leaves accumulated on the belt body 63, so that the tea leaves accumulated on the belt body 63 are dispersed, so as to prevent the excessively accumulated tea leaves from falling directly from the belt body 63 onto the conveyor belt 1 21, so that the conveyor belt 21 can be moved. The tea leaves on the conveyor belt 21 are evenly dispersed, and the belt body 63 drives the tea leaves to move. The tea leaves fall from the belt body 63 and fall on the conveyor belt 21. The atomizing humidifier 25 on the frame body 1 works to generate water mist, and the water mist is evenly sprayed on the upper surface of the tea leaves on the conveyor belt 21. The tea leaves fall from the conveyor belt 21 onto the inclined plate 23, and then fall from the inclined plate 23 onto the conveyor belt 22. The function of the inclined plate 23 is to turn over the tea leaves so that the side of the tea leaves humidified by the atomizing humidifier 25 faces downward, so that the atomizing humidifier 25 located above the conveyor belt 22 can soften the side of the tea leaves that has not been softened by the spray. The tea leaves are humidified and softened by atomization to achieve uniform humidification and softening of the upper and lower surfaces of the tea leaves. After humidification and softening, the tea leaves fall from the conveyor belt 22 onto the guide plate 26, and fall from the guide plate 26 into the hollow cylinder 51. The motor 2 56 drives the rod body 1 55 and the material-shifting rod 1 58 to rotate. The rotation of the material-shifting rod 1 58 and the extension claw 59 can drive the tea leaves in the hollow cylinder 51 to move, shift the tea leaves and lift them up. The atomizing nozzle 57 can humidify and soften the tea leaves again. The tea leaves discharged from the hollow cylinder 51 fall on the screen 1 33.
