Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery and relates to a rope-driven negative pressure picking and collecting device for high-quality tea installed on a mechanical arm. Background Art

[0002] my country is a major tea producing country. Tea trees are planted in a wide area and have a wide variety of tea varieties. High-quality tea has high requirements on the integrity and tenderness of fresh leaves, generally single buds, one bud and one leaf, and one bud and two leaves. Since most of the tea picking machinery on the market cannot meet the picking requirements of high-quality tea, at this stage, high-quality tea is mainly picked manually. This picking method has high labor intensity and low picking efficiency. In recent years, manual labor has become increasingly scarce, and the labor cost of leaf picking has gradually increased. In order to effectively improve the picking efficiency of high-quality tea and reduce picking costs and labor intensity, the development of high-quality tea picking equipment is imperative.

[0003] At present, the mechanical devices commonly used in the field of picking high-quality tea mostly use mechanical claws to directly clamp the tender buds for picking. This method has significant limitations: the tender buds are easily damaged, and the accuracy of picking is difficult to stably control. In view of this, the utility model provides an innovative negative pressure collection type high-quality tea picking device. The core design of this device is that it uses a collection tube to gently insert the tender buds and accurately cuts the tender buds with a rotating blade. At the same time, the built-in negative pressure device quickly completes the collection of tender buds, ensuring the efficiency and accuracy of picking high-quality tea. In addition, the structural design of its shearing device is simple, which not only improves work efficiency, but also brings great convenience to subsequent maintenance and tool replacement. By adopting this negative pressure collection picking method, it aims to solve the problems of tender bud damage and accuracy caused by traditional mechanical claw picking, and provide a more efficient and accurate solution for the picking of high-quality tea. Summary of the invention

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rope-driven negative pressure picking and collecting device for high-quality tea comprises: a collecting tube, a driving mechanism, and a shearing mechanism; the driving mechanism comprises a steering gear, a connecting rod, a driving shaft, a steel wire rope I, and a steel wire rope II; the steering gear is fixed to the collecting tube by screws, and the steering gear output shaft is connected to the steering gear disc by screws; there are three driving shafts, which are evenly distributed at 120 degrees on the outside of the collecting tube, the driving shaft is connected to the collecting tube by a bearing, and the outer ring of the bearing is interference fit with the collecting tube, and one of the driving shafts is connected to the steering gear disc by a coupling.

[0007] As a preferred technical solution of the utility model, there are three connecting rods, which are connected to the steering gear disc and the coupling at the same time, and can transmit power when the steering gear output shaft and the drive shaft are not on the same axis, making the device smaller and more compact.

[0008] As a preferred technical solution of the utility model, small holes are punched on the three driving shafts, and wire rope I and wire rope II are respectively fixed on the driving shafts through the small holes. Wire rope I is wound counterclockwise around the three driving shafts, and wire rope II is wound clockwise around the three driving shafts. When driving, the driving shafts can be tightened together to make the power transmission more precise; and a metal sleeve is fixed on the outer wall of the collecting tube to prevent wire ropes I and wire ropes II from cutting the collecting tube when being pulled.

[0009] As a preferred technical solution of the utility model, the shearing mechanism includes a blade fixing block and a blade; the blade fixing block is fixed to the lower end of the drive shaft by screws, the blade handle is S-shaped, and the blade is fixed by pressing the bent part of the handle with two screws at the bottom of the blade fixing block. The three blade fixing blocks and blades are evenly distributed and installed around the collection tube in the same way.

[0010] As a preferred technical solution of the utility model, the three blades are fixed with bolts by adjusting the number of gaskets to adjust the blade installation height, so that the three blades overlap each other when shearing the tender buds to avoid collision and interference, and the three blades converge inward when shearing to ensure that the tender buds of the famous and high-quality tea are always in the center of the collection tube, which is convenient for negative pressure collection.

[0011] Beneficial effects of the utility model:

[0012] When picking and collecting the famous and high-quality tea in the designated area, the steering gear shaft rotates to drive the steering gear disc to drive the coupling and the driving shaft to rotate through the connecting rod. At the same time, the steel wire ropes I and II fixed on the driving shaft begin to rotate clockwise, and the steel wire ropes I and II pull the driving shaft to rotate and drive the other two driving shafts to rotate synchronously, and at the same time drive the three blade fixing blocks to rotate together, and the three blades fixed on the blade fixing blocks converge inward at the same time for shearing, which can ensure that the position where the tender buds are cut off remains in the middle of the collection tube, which is convenient for negative pressure collection. After picking is completed, the steering gear rotates in the opposite direction, and the steel wire ropes I and II pull the driving shaft to rotate in the opposite direction, driving the other two driving shafts to rotate, so that the blade fixing block and the blade are reset; the blade installation method is simple, which is convenient for subsequent replacement; the picking and collecting device is small in size and light in weight, and the negative pressure device can be installed on the frame of the mechanical arm base, which reduces the load at the end of the mechanical arm as much as possible, improves the picking stability, and improves the picking efficiency.

[0023] Furthermore, the three driving shafts 4 are all punched with small holes, and the steel wire ropes I8 and II9 are respectively fixed on the driving shafts 4 through the small holes. The steel wire rope I8 is wound around the three driving shafts 4 counterclockwise, and the steel wire rope II9 is ​​wound around the three driving shafts 4 clockwise.
