Description

Technical Field

[0001] The present invention belongs to the field of tea picking equipment, and specifically relates to a drum-type tea picking machine and its working method. Background Art

[0002] A tea picking machine is a machine for harvesting tender fresh leaves from the top shoots of tea trees. Existing tea picking machines are all of the flat shearing type, generally including two shearing blades, a fuel engine or an electric motor, a handle, etc. Existing tea picking machines perform undifferentiated shearing. The harvested fresh leaves include some with one bud and one leaf, some with one bud and two leaves, and some with one bud and three leaves, with uneven sizes. Moreover, the bud leaves of the harvested tea fresh leaves are hooked to each other, making it extremely difficult to grade. Therefore, the tea fresh leaves picked by existing tea picking machines can only be used to process medium and low-grade tea. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a drum-type tea picking machine and its working method.

[0004] The technical solution of the present invention is as follows:

[0005] A drum-type tea picking machine includes a bracket and a cylindrical barrel. The barrel is arranged inside the bracket. A rotating shaft connected to the barrel is arranged on the center line of the barrel. Both sides of the bracket are respectively connected to the rotating shaft. A plurality of tea holes are evenly and densely arranged on the surface of the barrel. A fixing device fixedly connected to the bracket is arranged inside the barrel. The upper half of the fixing device is semi-circular, and the edge of the upper half of the fixing device is closely attached to the inner side of the barrel. The lower half of the fixing device is arc-shaped, and there is a certain distance between the edge of the lower half of the fixing device and the inner side of the barrel to form a cavity. A bottom shearing blade is fixedly arranged at the bottom of the bracket, and the plane where the bottom shearing blade is located is tangent to the outer surface of the bottom of the barrel. A side shearing blade is fixedly arranged at the front of the bracket, and the plane where the side shearing blade is located is tangent to the outer surface of the front of the barrel. A tea collector is fixedly arranged at the rear of the bracket.

[0006] The outer opening of the tea hole on the outer side of the barrel is larger than the inner opening of the barrel, and the tea hole is in the shape of a hollow frustum of a cone.

[0007] The diameter of the outer opening of the tea hole on the outer side of the barrel is 2 cm, the diameter of the inner opening of the tea hole on the inner side of the barrel is 1 cm, and the depth of the tea hole is 3 cm.

[0008] The outer opening of the tea hole on the outer side of the barrel is larger than the inner opening of the barrel, and the tea hole is in the shape of a hollow frustum of a pyramid.

[0009] The opening of the tea hole is square, the side length of the outer opening of the tea hole on the outer side of the barrel is 2 cm, the side length of the inner opening of the tea hole on the inner side of the barrel is 1 cm, and the depth of the tea hole is 3 cm.

[0010] The rotating shaft of the cylinder body is connected to a motor. The tea plucking machine further includes a power battery, and the motor and the power battery are arranged on the bracket or inside the fixing device.

[0011] Both sides of the bracket are in a cross shape. The bottom shearing blade is fixedly arranged at the bottom of the cross-shaped bracket, the side shearing blade is fixedly arranged at the front of the cross-shaped bracket, and the tea collector is fixedly arranged at the rear of the cross-shaped bracket.

[0012] The front part of the tea collector is in an arc shape that matches the cylinder body, and the tea collector wraps the arc part of the lower rear section of the cylinder body.

[0013] The bottom shearing blade and the side shearing blade respectively include an upper blade and a lower blade. Both the upper blade and the lower blade are long strip-shaped with serrations. The lengths of the upper blade and the lower blade are the same as the length of the cylinder body. Both the bottom shearing blade and the side shearing blade are electric. One of the upper blade and the lower blade of each pair of shearing blades is a movable blade connected to the motor, and the other is a fixed blade, or both the upper blade and the lower blade are movable blades connected to the motor.

[0014] The working method of the drum-type tea plucking machine is as follows: The cylinder body rotates forward at a constant speed under the drive of an external force, contacts the tea bush surface, and the new tea shoots enter the tea holes at the bottom. Then the bottom shearing blade cuts the new shoots. As the cylinder body rotates, the new tea shoots enter the horizontal position and contact the fixing device. If the length of the new tea shoot exceeds the depth of the tea hole, it is ejected by the fixing device, and the side shearing blade cuts the rear end that exceeds the depth of the tea hole. As the cylinder body rotates, the tea enters the position of the tea collector and falls off into the tea collector.

[0024] The present invention will be described in detail below with reference to the accompanying drawings.

[0025] As Figures 1 to 3 shown, a drum - type tea - picking machine and its working method of the present invention include a bracket 3 and a cylindrical cylinder 1. The cylinder 1 is arranged inside the bracket 3. A rotating shaft connected to the cylinder 1 is arranged on the central axis of the cylinder 1. Both ends of the rotating shaft can be connected to the cylinder 1 through a connecting rod 8 as Figure 3 shown. The two sides of the bracket 3 are respectively connected to the rotating shaft. A plurality of tea leaf holes 2 are uniformly and densely arranged on the surface of the cylinder 1. A fixing device 7 fixedly connected to the bracket 3 is arranged inside the cylinder 1. The fixing device 7 can be fixedly connected to both sides of the bracket 3 through fixing rods or the like. A through hole 11 is arranged on the fixing device 7. The rotating shaft passes through the through hole 11 on the fixing device 7. The upper half of the fixing device 7 is semi - circular, and the edge of the upper half of the fixing device 7 is closely attached to the inner side of the cylinder 1. The lower half of the fixing device 7 is arc - shaped, and there is a certain distance between the edge of the lower half of the fixing device 7 and the inner side of the cylinder 1 to form a cavity. A bottom cutting blade 5 is fixedly arranged at the bottom of the bracket 3. The plane where the bottom cutting blade 5 is located is tangent to the outer surface of the bottom of the cylinder 1. A side cutting blade 6 is fixedly arranged at the front of the bracket 3. The plane where the side cutting blade 6 is located is tangent to the outer surface of the front of the cylinder 1. A tea leaf collector 4 is fixedly arranged at the rear of the bracket 3.

[0026] As Figure 5 shown, in an embodiment of the present invention, the outer opening of the tea leaf hole 2 on the outer side of the cylinder 1 is larger than the inner opening of the cylinder 1, and the tea leaf hole 2 is in the shape of a hollow frustum of a cone. The diameter of the outer opening of the tea leaf hole 2 on the outer side of the cylinder 1 is 2 cm, the diameter of the inner opening of the tea leaf hole 2 on the inner side of the cylinder 1 is 1 cm, and the depth of the tea leaf hole 2 is 3 cm. Such a design of the tea leaf hole with a larger outer and smaller inner diameter can facilitate the entry of tea leaves into the tea leaf hole 2 and prevent them from falling out easily when the cylinder 1 rotates forward. And since the length of one bud and one leaf of the tea leaf is 2.7±0.2 cm, it can ensure that the cut tea leaves are all new shoots within 3 cm, and more than 80% are one bud and one leaf.

[0027] As Figure 6As shown, in another embodiment of the present invention, the outer opening of the barrel 1 of the tea leaf hole 2 is larger than the inner opening of the barrel 1. The tea leaf hole 2 is in the shape of a hollow quadrangular frustum. The opening of the tea leaf hole 2 is square. The side length of the outer opening of the barrel 1 of the tea leaf hole 2 is 2 cm, the side length of the inner opening of the barrel 1 of the tea leaf hole 2 is 1 cm, and the depth of the tea leaf hole 2 is 3 cm. Such a design of the square tea leaf hole, in addition to having the Figure 5 effects of the frustum-shaped tea leaf hole shown, since the square occupies a larger area than the circle, the gap between the tea leaf holes 2 on the barrel 1 can be reduced, preventing the tea leaves from being blocked by the gap between the tea leaf holes 2, enabling more tea leaves to enter the tea leaf holes 2 and improving the tea picking efficiency.

[0028] In an embodiment of the present invention, the rotating shaft of the barrel 1 is connected to a motor. The tea picking machine further includes a power battery, and the motor is powered by the power battery. The motor and the power battery can be arranged on the bracket 3 or inside the fixing device 7 as required. A switch for starting the motor is also provided on the tea picking machine. In this way, the motor can be started through the switch to make the barrel 1 rotate automatically, which is more labor-saving, efficient, and uniform than manually rotating the barrel.

[0029] As Figure 3 shown, both sides of the bracket 3 are in a cross shape. The fixing device 7 can be fixedly connected to both sides of the cross-shaped bracket through fixing rods. The bottom cutting blade 5 is fixedly arranged at the bottom of the cross-shaped bracket, the side cutting blade 6 is fixedly arranged at the front of the cross-shaped bracket, and the tea leaf collector 4 is fixedly arranged at the rear of the cross-shaped bracket. The front part of the tea leaf collector 4 is in an arc shape that matches the barrel 1, and the tea leaf collector 4 wraps the lower arc part of the barrel 1. The tea leaves can fall into the tea leaf collector 4 when the barrel 1 rotates to the position of the tea leaf collector 4.

[0030] As Figure 7 shown, the bottom cutting blade 5 and the side cutting blade 6 respectively include an upper blade 9 and a lower blade 10. Both the upper blade 9 and the lower blade 10 are long strip-shaped and serrated. The lengths of the upper blade 9 and the lower blade 10 are the same as the length of the barrel 1, so that all the tea leaves in the length direction of the barrel 1 can be cut at one time. In an embodiment of the present invention, both the bottom cutting blade 5 and the side cutting blade 6 are electric. One of the upper blade 9 and the lower blade 10 of each pair of cutting blades is a movable blade connected to the motor, and the other is a fixed blade, or both the upper blade 9 and the lower blade 10 are movable blades connected to the motor. When working, the switch of the electric cutting blade is turned on to automatically cut the tea leaves, and the serrations are opened and closed by the relative movement of the upper blade 9 and the lower blade 10 to cut the tea leaves.

[0031] The working method of a drum - type tea - picking machine of the present invention is as follows: The cylinder 1 rotates forward uniformly under the drive of an external force, contacts the tea bush surface, and the new tea shoots enter the tea holes 2 at the bottom. Then, the new shoots are sheared by the bottom shear blade 5. As the cylinder 1 rotates, the new tea shoots enter the horizontal position and contact the fixing device 7. If the length of the new tea shoot exceeds the depth of the tea hole 2, which is 3 cm, it is ejected by the fixing device 7, and the rear end exceeding the depth of the tea hole 2 is sheared by the side shear blade 6. As the cylinder 1 rotates, the tea enters the position of the tea collector 4 and falls off into the tea collector 4.

[0032] Through experiments, for a drum - type tea - picking machine of the present invention, all the obtained new tea shoots are less than 3 cm. More than 80% of these new shoots are basically one - bud - one - leaf, which can be used for picking and processing high - grade standardized tea.

[0033] The above - mentioned are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included within the protection scope of the present invention.
