[0001] The utility model relates to the technical field of tea picking machines, in particular to a tea picking machine for Pu-erh tea production. Background Art

[0002] As a tea with a long history, the taste of Pu-erh tea is pursued by many tea lovers. With the continuous development of technology, high-efficiency tea picking has become a trend. Tea picking machines are widely used in the tea picking industry and are popular among tea farmers for their advantages of speed and labor saving.

[0003] Tea picking machines are an important part of the tea picking industry. Currently, most tea picking machines on the market usually pick young leaves and old leaves into the same collection box when picking tea, increasing the cost of manual tea sorting. Since the leaf stalks of young leaves and old leaves have different toughness, using the same shearing machine during picking often damages the integrity of the tea leaves. At the same time, when picking tea in the mountains, affected by the mountain environment, the growth of tea leaves is uneven, which causes inconvenience to the machine picking.

[0004] Therefore, there is an urgent need to provide a tea picking machine for Pu-erh tea production to solve the above problems. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that the structure of the existing tea picking machine is too simple and usually cannot complete the separation of young leaves and old leaves. Due to the difference in the leaf stalks of the two types of leaves, it often affects the integrity of the tea leaves. At the same time, due to the uneven height of the tea fields on the tea mountains, it affects the machine picking.

[0006] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a tea picking machine for Pu-erh tea production, including a support flat plate, a tea leaf winding device is fixedly connected to the upper end of the support flat plate, a shearing device is fixedly connected to the opening position of the tea leaf winding device, an old leaf box is fixedly connected to the side of the tea leaf winding device away from the shearing device, and the old leaf box is communicated with the side of the tea leaf winding device away from the shearing device;

The side of the rotating shaft away from the tender leaf box is rotatably connected to the box body through penetration. A stepping motor is installed on the side of the rotating shaft away from the tender leaf box. The output shaft of the stepping motor is fixedly connected to the rotating shaft.

[0012] Through the above technical solution, the motor drives the rotating shaft and the rotating discs to rotate. The leaf rolling shafts fixed on the rotating discs simultaneously perform circular motions. The evenly distributed leaf rolling shafts sweep the leaves into the rear side of the box body through the brushes.

[0013] The present utility model is further configured as follows: The shearing device includes a tool protection frame fixed at the open end of the box body. A limiting groove is provided at a position of the tool protection frame away from the box body. The limiting groove is slidably matched with the first tool.

Baffles are fixedly connected to both sides of the concave circular slider. A linear chute is provided between the circular slide rails, and the linear chute is fixedly connected to the baffle.

[0018] Through the above technical solution, the landing gear adjusts the height of the young leaf collection device. The circular slide rail and the concave circular slider cooperate with each other, and the linear chute and the circular slider cooperate with each other, enabling the clamping jaws to move freely on a plane.

[0019] The present utility model is further configured as follows: A circular slider is slidably connected inside the linear chute. A cylindrical housing is fixedly connected to the lower end of the circular slider. A clamping jaw is rotatably connected inside the cylindrical housing. A roller is rotatably connected to the upper end of the clamping jaw. A circular pipe is installed inside the cylindrical housing. An inclined circular ring is fixedly connected to the lower end of the circular pipe, and the inclined circular ring is slidably connected to the roller.

[0020] Through the above technical solution, the roller at the upper end of the clamping jaw slides on the inclined circular ring. The closer the roller is to the upper end of the inclined circular ring, the farther it is pushed away from the center of the circle.

[0022] Through the above technical solution, the motor drives the gear to rotate. The rack meshed with the gear moves up and down, and the circular pipe fixedly connected to the rack moves up and down. When the circular pipe moves down, the inclined circular ring moves down, and the roller is pushed away from the center of the circle. At this time, the clamping jaw rotates, and the lower end of the clamping jaw tightens to clamp the young leaves.

[0023] The present utility model is further configured as follows: The scissor lift includes a pair of chute plates fixed to the upper end of the support frame. A plurality of connecting plates are provided between the chute plates.

A second motor is installed on one side of the threaded lead screw, and the second motor is fixedly connected to the support plate, and the output end of the second motor is fixedly connected to the threaded lead screw.

[0024] Through the above technical solution, when the motor rotates, the threaded lead screw fixedly connected to the output end of the motor rotates, and the threaded block moves on the threaded lead screw, driving the connecting plate to move. The cylindrical slider on the upper surface of the connecting plate slides along the chute plate, the inclination angle of the connecting plate changes, and it obliquely approaches or moves away from the threaded lead screw, and the scissor lift is lifted or lowered.

[0025] The beneficial effects of the present utility model are as follows:

[0026] 1. By designing a tender leaf collection device and a shearing device, the rack and pinion drive the inclined ring fixed to the circular pipe to move up and down, realizing the opening and closing of the clamping jaws to pick the tender leaves. Then, the slider on the circular chute makes a circular motion, causing the connecting block to reciprocate, and the first cutter reciprocates to shear the old leaves. It not only completes the collection of tender leaves and old leaves in different ways but also realizes the separation and collection of the two types of leaves.

[0027] 2. By designing a shearing lift, the motor drives the threaded lead screw to rotate, and the threaded block on the threaded lead screw makes a horizontal movement. When the threaded block approaches the center position of the threaded lead screw, the inclination angle of the connecting block becomes larger, and the shearing lift moves downward; conversely, it moves upward, realizing the picking requirements for tea fields at different heights.
