Description

Technical Field

[0001] The invention relates to a tea picking device, in particular to a tea grading and picking device. Background Art

[0002] There are many varieties of tea, each with its own unique flavor and quality characteristics. Different types of tea have very different requirements for picking standards. For example, when making high-quality green tea, it is usually necessary to pick fresh buds with one bud and one leaf or one bud and two leaves to ensure the fragrance and fresh 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] In the process of tea picking, manual picking or mechanical picking is mainly used. The advantage of manual picking is that it can finely distinguish the tender leaves at the tip of the tea tree and other secondary tea leaves, and pick and classify them separately, but this method is more labor-intensive. In contrast, mechanical picking usually uses saw blade cutting, which can quickly collect all the tea leaves on the upper part of the tea tree, but because it is impossible to perform graded screening, the picked tea leaves need further manual screening, which makes subsequent operations more cumbersome and affects processing efficiency. Summary of the invention

DETAILED DESCRIPTION

[0030] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0031] A tea grading and picking device, such as Figure 1-Figure 9 As shown, it includes a picking frame 1, a partition plate 12, a handle 2, a picking mechanism and a cutting mechanism. The upper parts of the left and right sides of the picking frame 1 are connected with handles 2. The lower part of the picking frame 1 is connected with a partition plate 12 to divide the inside of the picking frame 1 into two layers, and a plurality of picking grooves 11 are evenly spaced at the lower front part of the picking frame 1. The picking frame 1 is provided with a picking mechanism for picking young leaves of tea trees and a cutting mechanism for picking the next level of tea leaves.

[0032] like Figure 3-Figure 7As shown, the picking mechanism includes a side frame 31, a sleeve 32, a guide frame 33, a clamping plate 34, a driving motor 35, a belt drive group 36, an extrusion arc plate 37, an elastic member 38 and a convex shaft 39. The left and right sides of the picking frame 1 are connected to the side frames 31, and the sleeve 32 is rotatably connected between the two side frames 31. The sleeve 32 is provided with a plurality of groups of openings 331 evenly spaced along the circumferential direction, and each group of openings 331 is provided with a plurality of openings evenly spaced on the sleeve 32. A guide frame 33 is slidably connected in each opening 331, and the guide frame 33 can slide in the opening 331 along the radial direction of the sleeve 32. Two clamping plates 34 are slidably connected in each opening 331, and the clamping plates 34 can slide along the axial direction of the opening 331. A plurality of groups of guide frames 33 are connected, and each group of guide frames 33 is provided with a plurality of evenly spaced openings. The interval sliding is set on the sleeve 32, and a driving motor 35 is installed in the picking frame 1. A belt transmission group 36 is installed between the output shaft of the driving motor 35 and the sleeve 32. An extrusion arc plate 37 is connected between the two side frames 31, and the extrusion arc plate 37 is located in the sleeve 32. The lower part of the extrusion arc plate 37 is inclined. The inner side of the guide frame 33 can contact the extrusion arc plate 37 by rotating. Two elastic members 38 are connected between the guide frame 33 and the sleeve 32. The elastic member 38 is a reset spring. A convex shaft 39 is connected to the lower part of the clamping plate 34. The left and right sides of the guide frame 33 are provided with oblique grooves, and the convex shaft 39 is located in the oblique groove, so that the guide frame 33 can squeeze the convex shaft 39 through the oblique groove when moving, thereby driving the two clamping plates 34 to move closer to or away from each other.

[0033] like Figure 8 and Fig. 9 As shown, the cutting mechanism includes a roller 41, a belt transmission group 42, an inclined extrusion disk 43, an extension rod 44 and a cutting saw 45. The roller 41 is rotatably connected to the lower right side of the picking frame 1, and a belt transmission group 42 is installed between the roller 41 and the output shaft of the driving motor 35. The roller 41 is connected to the inclined extrusion disk 43. The lower part of the picking frame 1 is slidably connected to the cutting saw 45. The front side of the cutting saw 45 is located in the picking groove 11. Two extension rods 44 are connected to the right side of the top of the cutting saw 45, and 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, the device can be used. When in use, the picking frame 1 is first moved to the top of the tea tree so that the tender leaves above the tea tree are located at the bottom of the picking frame 1, and then the picking frame 1 can be pulled to move along the tea tree, and 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 to drive the sleeve 32 to rotate through the belt transmission group 1 36. The sleeve 32 can drive the guide frame 33 to rotate when rotating. The guide frame 33 can contact the extrusion arc plate 37 when rotating and be squeezed by the inclined surface of the extrusion arc plate 37, so that the guide frame 33 moves outward along the opening 331, and the elastic member 1 38 is compressed. At this time, the inclined groove on the guide frame 33 can squeeze the two convex shafts 39 close to each other, thereby driving the two clamping plates 34 close to each other. When the two clamping plates 34 are close to each other, they can clamp the tips of the branches. The young leaves are then pulled out by the sleeve 32 when it continues to rotate. When the guide frame 33 rotates to disengage from the extrusion arc plate 37, the guide frame 33 is reset under the action of the elastic member 38. At this time, the two clamping plates 34 also move away from each other and no longer clamp the young leaves, and the young leaves fall into the upper layer of the picking frame 1. When the driving motor 35 is operating, the roller 41 is also driven to rotate through the belt transmission group 2 42. The roller 41 drives the inclined extrusion plate 43 to rotate when it rotates. The rotation of the inclined extrusion plate 43 can repeatedly squeeze the two extension rods 44 to move, thereby driving the cutting saw 45 to move back and forth left and right. The inferior tea leaves located above the picking groove 11 will be cut off by the cutting saw 45 and fall below the picking frame 1. In this way, the device can be used to pick tea leaves, and when picking, the young leaves can be separated from other tea leaves to achieve the effect of graded picking.

[0035] like Fig.10 As shown, an elastic clamping air cushion 5 is also included, and the two clamping plates 34 of the same opening 331 are connected to the elastic clamping air cushion 5 on the sides close to each other.

[0036] When the clamping plate 34 clamps the young leaves, the elastic clamping air cushion 5 can be used to clamp the young leaves. The elastic setting of the elastic clamping air cushion 5 can protect the young leaves and avoid damage to the young leaves.

[0037] like Figure 1 and Figure 3 As shown, it also includes a lifting mechanism, which includes a guide sleeve 51, a T-shaped frame 52, an automatic walking track 53 and a lifting cylinder 54. The two handles 2 are connected to the guide sleeve 51, the lower part of the guide sleeve 51 is connected to the T-shaped frame 52, the automatic walking track 53 is installed on the T-shaped frame 52, and the 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 rise and fall.

[0038] When the picking frame 1 in the device is placed above the tea tree, the automatic walking tracks 53 on both sides can be located on the ground on both sides of the tea tree. Then the automatic walking tracks 53 can be controlled to move to drive the device to move, thereby driving the picking frame 1 to move for picking. In this way, there is no need for manual operation to pull the picking frame 1 to move, which makes the operation more convenient. When the height of the picking frame 1 needs to be adjusted, the telescopic rod of the lifting cylinder 54 can be extended and retracted to drive the guide sleeve 51 to move up and down for adjustment, so as to adjust the overall height of the picking frame 1.

[0039] like Fig.11 As shown, a fan 6 is also included, and a plurality of fans 6 are evenly spaced and installed on the upper front side of the picking frame 1.

[0040] like Fig.12 As shown, a collecting bag 8 is also included. Two discharge ports 81 are opened at the rear side of the picking frame 1. The collecting bag 8 is arranged at the discharge ports 81. The two discharge ports 81 are respectively connected to the upper and lower layers of the picking frame 1.

[0041] like Fig.13 As shown, it also includes a blowing pipe 9. A plurality of blowing pipes 9 are evenly spaced and connected to the upper part of the picking frame 1. The air outlet ends of the blowing pipes 9 are aligned with the lower layer of the picking frame 1.

[0042] When the young leaves fall on the upper layer in the picking frame 1, the fan 6 can be controlled to blow the young leaves backward to the upper discharge port 81, and the young leaves can be collected by the upper collecting bag 8, while the blowing pipe 9 can guide the wind from the upper layer in the picking frame 1 to the lower layer, so that the tea leaves below are blown to the collection bag 8 below through the lower discharge port 81, and the tea leaves are collected by the lower collection bag 8. In this way, the tea leaves can be collected more conveniently.

[0043] like Fig.11 and Fig.13 As shown, a grille 7 is also included. The lower front part of the picking frame 1 is connected to the grille 7. The grille 7 is used to comb the branches of the tea tree. When the picking frame 1 moves along the tea tree, the tea leaves above the tea tree will pass through the grille 7, and the tea leaves will be combed by the grille 7 to facilitate the clamping work of the clamping plate 34.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
