Description

Technical Field

[0001] The present invention relates to a tea picking device, and particularly to a device for grading and picking tea leaves. Background Art

[0002] There are a wide variety of tea varieties, and each type of tea has its unique flavor and quality characteristics. The requirements for picking standards vary greatly for different types of tea. For example, when making high-grade green tea, it is usually necessary to pick fresh tender buds of one bud with one leaf or one bud with two leaves to ensure the fresh fragrance and brisk taste of the tea; while for some black teas, slightly more mature leaves may be required to ensure the unique mellow taste of black tea.

[0003] During the tea picking process, manual picking or mechanical picking methods are mainly used. The advantage of manual picking is that it can finely distinguish the tender leaves at the top of the tea tree from other secondary tea leaves and pick and classify them separately, but this method is labor-intensive. In contrast, mechanical picking usually uses a saw blade cutting method, which can quickly collect all the tea leaves on the upper part of the tea tree. However, since it cannot perform grading and screening, the picked tea leaves need further manual screening, which makes the subsequent operations more cumbersome and affects the processing efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a device for grading and picking tea leaves.

[0005] A device for grading and picking tea leaves includes a picking frame and a handle. The upper parts on both sides of the picking frame are connected with handles. It further includes a partition board, a picking mechanism, and a cutting mechanism. The lower part inside the picking frame is connected with a partition board, dividing the interior of the picking frame into upper and lower layers. A plurality of picking grooves are evenly spaced and opened at the lower part of the picking frame. Inside the picking frame, there is a picking mechanism for picking the tender leaves of the tea tree and a cutting mechanism for picking the secondary tea leaves. The picking mechanism includes side frames, sleeves, guide frames, and clamping plates. Side frames are connected to both sides of the picking frame, and a sleeve is rotatably connected between the two side frames. A plurality of groups of openings are evenly spaced along the circumferential direction on the sleeve, and each group of openings has a plurality of openings evenly spaced on the sleeve. A guide frame is slidably connected inside each opening, and two clamping plates are slidably connected inside each opening.

[0006] As an improvement to the above solution, the picking mechanism further includes a driving motor, a first belt transmission group, a squeezing arc plate, a first elastic member, and a convex shaft. A driving motor is installed inside the picking frame. A first belt transmission group is installed between the output shaft of the driving motor and the sleeve.

The lower part of the clamping plate is connected with a convex shaft. Oblique slots are formed on both sides of the guiding frame. The convex shaft is located in the oblique slots.

[0007] As an improvement to the above solution, the cutting mechanism includes a rotating roller, a second belt transmission group, an inclined squeezing disk, an extension rod, and a cutting saw. A rotating roller is rotatably connected to the picking frame. A second belt transmission group is installed between the rotating roller and the output shaft of the driving motor. An inclined squeezing disk is connected to the rotating roller. A cutting saw is slidably connected to the lower part of the picking frame. The front side of the cutting saw is located in the picking groove. Two extension rods are connected to the top of the cutting saw. The two extension rods are respectively located on both sides of the inclined squeezing disk.

[0008] As an improvement to the above solution, it further includes an elastic clamping air cushion. Elastic clamping air cushions are connected to the mutually approaching sides of the two clamping plates of the same opening.

[0009] As an improvement to the above solution, it further includes a lifting mechanism. The lifting mechanism includes a guide sleeve, a T-shaped frame, an automatic walking track, and a lifting cylinder. Guide sleeves are connected to both handles. A T-shaped frame is connected to the lower part of the guide sleeve. An automatic walking track is installed on the T-shaped frame. A lifting cylinder is installed on the T-shaped frame. The telescopic rod of the lifting cylinder is connected to the guide sleeve.

[0010] As an improvement to the above solution, it further includes a fan. A plurality of fans are evenly spaced and installed on the picking frame.

[0011] As an improvement to the above solution, it further includes a collection bag. Two discharge ports are formed on the picking frame. Collection bags are arranged at the discharge ports. The two discharge ports are respectively communicated with the upper and lower layers of the picking frame.

[0012] As an improvement to the above solution, it further includes a blowing air pipe. A plurality of blowing air pipes are evenly spaced and communicated with the upper part of the picking frame. The air outlet ends of the blowing air pipes are aligned with the lower layer of the picking frame.

Detailed implementation manners

[0030] The following describes the implementation manners of the present invention with reference to the attached drawings.

[0031] A tea grading and picking device, as Figures 1 - 9 shown, includes a picking frame 1, a partition board 12, a handle 2, a picking mechanism and a cutting mechanism. The handle 2 is connected to the upper parts of the left and right sides of the picking frame 1. The partition board 12 is connected to the lower part inside the picking frame 1, dividing the inside of the picking frame 1 into upper and lower layers. A plurality of picking grooves 11 are evenly spaced and opened at the lower part of the front side of the picking frame 1. A picking mechanism for picking tender tea leaves and a cutting mechanism for picking the next-level tea leaves are provided inside the picking frame 1.

[0032] As Figures 3 - 7As shown in the figure, the picking mechanism includes side frames 31, sleeves 32, guide frames 33, clamping plates 34, drive motors 35, first belt drive groups 36, extrusion arc plates 37, first elastic members 38, and convex shafts 39. Side frames 31 are connected to both the left and right sides of the picking frame 1. A sleeve 32 is rotatably connected between the two side frames 31. A plurality of groups of openings 331 are evenly spaced circumferentially on the sleeve 32. Each group of openings 331 has a plurality of them which are evenly spaced on the sleeve 32. A guide frame 33 is slidably connected in each opening 331. The guide frame 33 can slide radially along the sleeve 32 within the opening 331. Two clamping plates 34 are slidably connected in each opening 331. The clamping plates 34 can slide axially along the opening 331. A plurality of groups of guide frames 33 are connected, and each group of guide frames 33 has a plurality of them which are evenly spaced and slidably arranged on the sleeve 32. A drive motor 35 is installed inside the picking frame 1. A first belt drive group 36 is installed between the output shaft of the drive motor 35 and the sleeve 32. An extrusion arc plate 37 is connected between the two side frames 31. The extrusion arc plate 37 is located inside the sleeve 32. The lower part of the extrusion arc plate 37 is inclined. The inner side of the guide frame 33 can rotate and contact the extrusion arc plate 37. Two first elastic members 38 are connected between the guide frame 33 and the sleeve 32. The first elastic members 38 are return springs. The lower part of the clamping plate 34 is connected with a convex shaft 39. Oblique grooves are opened on both the left and right sides of the guide frame 33. The convex shaft 39 is located in the oblique grooves, so that when the guide frame 33 moves, it can squeeze the convex shaft 39 to move through the oblique grooves, thereby driving the two clamping plates 34 to approach or move away from each other.

[0033] As Figure 8 and Figure 9 As shown in the figure, the cutting mechanism includes a rotating roller 41, a second belt drive group 42, an inclined extrusion disk 43, extension rods 44, and a cutting saw 45. A rotating roller 41 is rotatably connected to the lower right side of the picking frame 1. A second belt drive group 42 is installed between the rotating roller 41 and the output shaft of the drive motor 35. An inclined extrusion disk 43 is connected to the rotating roller 41. A cutting saw 45 is slidably connected to the lower part of the picking frame 1. The front side of the cutting saw 45 is located in the picking groove 11. Two extension rods 44 are connected to the upper right side of the cutting saw 45. The two extension rods 44 are respectively located on the left and right sides of the inclined extrusion disk 43.

[0034] When it is necessary to pick tea leaves, this device can be used. When in use, first carry the picking frame 1 above the tea tree so that the tender leaves above the tea tree are located below the picking frame 1. Then, the picking frame 1 can be pulled along the tea tree. The picking groove 11 can gather the branches above the tea tree. At the same time, the driving motor 35 can be controlled to operate, and the sleeve 32 is driven to rotate through the first belt transmission group 36. When the sleeve 32 rotates, it can drive the guide frame 33 to rotate. When the guide frame 33 rotates, it can contact the extrusion arc plate 37 and be extruded by the inclined surface of the extrusion arc plate 37, so that the guide frame 33 moves outward along the opening 331, and the first elastic member 38 is compressed. At this time, the inclined groove on the guide frame 33 can squeeze the two convex shafts 39 to approach each other, thereby driving the two clamping plates 34 to approach each other. When the two clamping plates 34 approach each other, they can clamp the tender leaves at the tip of the branch. Subsequently, when the sleeve 32 continues to rotate, the tender leaves can be pulled out. When the guide frame 33 rotates away from the extrusion arc plate 37, under the action of the first elastic member 38, the guide frame 33 resets. At this time, the two clamping plates 34 also move away from each other and no longer clamp the tender leaves, and the tender leaves fall into the upper layer of the picking frame 1. When the driving motor 35 operates, it also drives the roller 41 to rotate through the second belt transmission group 42. When the roller 41 rotates, it drives the inclined extrusion disk 43 to rotate. The rotation of the inclined extrusion disk 43 can repeatedly squeeze the two extension rods 44 to move, thereby driving the cutting saw 45 to reciprocate left and right. And the tea leaves of a lower grade located above the picking groove 11 will be cut by the cutting saw 45 and fall into the lower part of the picking frame 1. In this way, this device can be used to pick tea leaves, and during picking, the tender leaves and other tea leaves can be separated to achieve the effect of grading picking.

[0035] As Figure 10 shown, it further includes an elastic clamping air cushion 5. Elastic clamping air cushions 5 are connected to the sides of the two clamping plates 34 that approach each other in the same opening 331.

[0036] During the process of the clamping plate 34 clamping the tender leaves, it can be clamped through the elastic clamping air cushion 5. Through the elastic setting of the elastic clamping air cushion 5, the tender leaves can be protected from damage.

[0037] As Figure 1 and Figure 3 shown, it further includes a lifting mechanism. The lifting mechanism includes a guide sleeve 51, a T-shaped frame 52, an automatic walking track 53, and a lifting cylinder 54. Guide sleeves 51 are connected to both of the two handles 2. The lower part of the guide sleeve 51 is connected to a T-shaped frame 52. An automatic walking track 53 is installed on the T-shaped frame 52. A lifting cylinder 54 is installed on the T-shaped frame 52. The telescopic rod of the lifting cylinder 54 is connected to the guide sleeve 51, so that the operation of the telescopic rod of the lifting cylinder 54 can drive the guide sleeve 51 to lift and lower.

[0038] When placing the picking basket 1 in the device above the tea tree, the automatic walking tracks 53 on both sides can be positioned on the ground on both sides of the tea tree. Subsequently, the movement of the automatic walking tracks 53 can be controlled to drive the movement of the device, thereby driving the movement of the picking basket 1 for picking work. In this way, there is no need for manual operation to pull the picking basket 1 to move, and the operation is more convenient. When it is necessary to adjust the height of the picking basket 1, the telescopic rod of the lifting cylinder 54 can be extended or retracted to drive the guide sleeve 51 to move up and down for adjustment, so as to adjust the overall height of the picking basket 1.

[0039] As Figure 11 shown, it further includes a fan 6. A plurality of fans 6 are evenly spaced and installed on the upper part of the front side of the picking basket 1.

[0040] As Figure 12 shown, it further includes a collection bag 8. Two discharge ports 81 are provided at the rear side of the picking basket 1, and a collection bag 8 is arranged at the discharge ports 81. The two discharge ports 81 are respectively communicated with the upper and lower layers of the picking basket 1.

[0041] As Figure 13 shown, it further includes a blowing air pipe 9. A plurality of blowing air pipes 9 are evenly spaced and communicated with the upper part of the picking basket 1. The air outlet end of the blowing air pipe 9 is aligned with the lower layer of the picking basket 1.

[0042] When the tender leaves fall on the upper layer inside the picking basket 1, the operation of the fan 6 can be controlled to blow the tender leaves backward to the upper discharge port 81, and the tender leaves are collected by the upper collection bag 8. The blowing air pipe 9 can guide the air inside the upper layer of the picking basket 1 to the lower layer, so as to blow the tea leaves below to the lower collection bag 8 through the lower discharge port 81, and the tea leaves are collected by the lower collection bag 8. In this way, it is more convenient to collect the tea leaves.

[0043] As Figure 11 and Figure 13 shown, it further includes a grille 7. The grille 7 is connected to the lower part of the front side of the picking basket 1. The grille 7 is used to comb the branches of the tea tree. During the movement of the picking basket 1 along the tea tree, the tea leaves above the tea tree will pass through the grille 7, and the tea leaves are combed through the grille 7 to facilitate the clamping work of the clamping plate 34.

[0044] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
