[0002] Grapes are woody vines belonging to the genus *Vitis* in the family Vitaceae. Their fruit are berries, mostly round or oval in shape, with varying colors depending on the variety. Young grape stems may be covered with woolly hairs. The leaves are papery, ovate or round, and the inflorescence is usually conical. Grape inflorescences are large and long, with small sepals. When ripe, the berries are purplish-black or red with a greenish tinge. The flowering period is from April to May, and the fruiting period is from August to September. To ensure the best grape growth, it is necessary to manage the flowering period. A common method is to thin the flowers, which reduces the nutrient consumption of the grapes, thus ensuring the size and taste of the berries.

[0014] 1. This invention designs a cutting device specifically for thinning grape flowers. The grape thinning cutting device includes a thinner body, a rotary cutting component, a vibrating pollen-dropping mechanism, a sealing mechanism, and a pollen sprayer. When thinning grape flowers is required, the worker holds the thinner body and clamps the main grape bunch. After clamping, the worker slowly pulls the thinner body. During the pulling process, the rotary cutting component rotates synchronously and intermittently cuts off the flower clusters on the main grape bunch, removing excess flower clusters. The removed flower clusters fall to the vibrating pollen-dropping mechanism, which vibrates and drops the pollen from the flower clusters. The dropped pollen is then guided into the pollen sprayer, which allows for artificial pollination of the grape flowers, greatly improving the functionality of the device.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please refer to Figures 1-4. This invention provides a technical solution: a cutting mechanism for a grape thinner, comprising a thinner body, a rotary cutting assembly, a vibrating pollen-shaking mechanism, a sealing mechanism, and a powder sprayer. The thinner body includes two sets of handles 1 rotatably connected and two shear heads 2 and 3 fixed to the ends of the two sets of handles 1. Both shear heads 2 and 3 have a clamping opening 4 formed in the middle, with an arc-shaped groove 5 inside the clamping opening 4. The rotary cutting assembly is divided into two sets and respectively installed on shear head 2. In the middle of the second shear head 3, the rotary shearing assembly includes a floating mounting frame 6, a motor 7, a rotating disk 8, and a shearing blade 9. The floating mounting frame 6 is built into one side of the clamp 4 and includes a support frame 11 with a mounting opening 10 at its end and a return spring 12 built into the mounting opening 10. The outer end of the return spring 12 is connected to the motor 7, and the power output end of the motor 7 is connected to the rotating disk 8. The edge of the rotating disk 8 is connected to the shearing blade 9, which is rotatably disposed in the arc-shaped groove 5. An inner groove 13 is provided on one side of the lower clamp 4. A vibrating pollen-dropping mechanism is installed in the inner groove 13 and includes an arc-shaped screen 14 and a actuator 15 disposed on one side of the arc-shaped screen 14. One end of the arc-shaped screen 14 is fixedly connected to the inner wall of the inner groove 13, and the other end is in contact with the actuator 15. The actuator 15 is fixed to the inner wall of the inner groove 13. An inner cavity 16 is formed inside the lower clamp 4. A closing mechanism is built into the bottom of the inner cavity 16 and includes a moving rod 17 and a mechanism fixed to the moving rod 17. The inner end of the rod 17 has an arc-shaped baffle 18. The outer end of the moving rod 17 is threaded with a limit nut 19. The limit nut 19 is connected to the end of the second cutter head 3. The second cutter head 3 has a moving groove 20. The moving rod 17 is located in the moving groove 20. The powder sprayer includes a spray chamber 21 opened on the second cutter head 3 and a blower 22 installed at the tail of the spray chamber 21. The air outlet of the blower 22 is connected to a cover 23 through a pipe. The cover 23 is built into the spray chamber 21. The front end of the spray chamber 21 is equipped with a spray pipe 24.
[0023] Further improvements, as shown in Figure 4, include a fan-shaped plate 25 and an arc-shaped blade 26 fixed to the outer end of the fan-shaped plate 25. An arched protrusion 27 is fixed to the back of the fan-shaped plate 25, and the end of the arc-shaped blade 26 has a blade-shaped structure.
[0024] As further improved, as shown in Figure 1, a contact block 28 is fixed on one side of the clamp 4. The contact block 28 is used in conjunction with the arched protrusion 27. During the rotation of the shearing blade 9, the arched protrusion 27 on the back acts intermittently on the contact block 28, so that the shearing blade 9 moves laterally in the arc groove 5 to complete the shearing action of the grape flower.
[0025] As further improved, as shown in Figure 2, the surface of the arc-shaped screen 14 is formed with several sets of mesh holes 29 and a contact piece 30 is fixed near the side of the actuator 15. The contact piece 30 contacts the actuator 15 to facilitate the shaking off of pollen.
[0026] Further improvements, as shown in Figure 2, include a second motor 31 and a rotating disk 32 fixed to the power output end of the second motor 31. A toggle block 33 is fixed to the edge of the rotating disk 32. The toggle block 33 has a fan-shaped structure and one end is narrower than the other end. The second motor 31 drives the rotating disk 32 to rotate. During the rotation, the rotating disk 32 drives the toggle block 33 to rotate synchronously. The toggle block 33 acts intermittently on the contact piece 30, causing the arc-shaped screen 14 to shake and vibrate the cut flowers on the arc-shaped screen 14, causing the pollen on the flowers to fall off.
[0027] As further improved, as shown in Figure 3, the inner cavity 16 and the spray cavity 21 are connected and a passage 34 is formed at the connection. An arc-shaped baffle 18 is located at the passage 34. The size of the arc-shaped baffle 18 is larger than the size of the passage 34, which facilitates the introduction of pollen.
[0028] As further improved, as shown in Figure 3, the cover 23 has a hollow hemispherical structure and its edge is in sealed contact with the inner wall of the spray cavity 21. The airflow can be introduced into the spray cavity 21 through the cover 23 to spray the pollen inside.
[0029] Specifically, the nozzle 24 has a two-section structure and includes a tube body 35 and a conical tube 36 fixed to the outer end of the tube body 35. The outer diameter of the conical tube 36 is smaller than the inner diameter, and it is used to spray pollen onto the grape flowers to achieve the purpose of pollination.
[0030] In use: When thinning grape blossoms, the worker holds two sets of handles 1 and places the first and second shears 2 and 3 at the connection between the main grape bunch and the vine. At this time, the main grape bunch is located within the two sets of clamps 4. Then, the motor 1 7 is turned on, which drives the rotating disk 8 and the shearing blade 9 to rotate synchronously. During the rotation, the arched protrusion 27 on the back intermittently acts on the contact block 28, causing the shearing blade 9 to move laterally within the arc-shaped groove 5, completing the shearing action on the grape blossoms. At the same time, the worker pulls the thinning device body along the main grape bunch, and during the movement, the shearing blade 9 intermittently cuts the blossoms on the main grape bunch. The cut blossoms fall into the embedded groove 1. Inside the cavity 3, the rotating disk 32 is driven to rotate by the motor 31. During the rotation of the rotating disk 32, the actuating block 33 rotates synchronously. The actuating block 33 acts intermittently on the contact piece 30, causing the arc-shaped screen 14 to shake and vibrate the flowers cut off on the arc-shaped screen 14, causing the pollen on the flowers to fall off. The fallen pollen enters the inner cavity 16. When it is necessary to pollinate the grape flowers, the staff pulls the moving rod 17 and the arc-shaped baffle 18, causing the arc-shaped baffle 18 to disengage from the opening 34. The pollen falls into the spray chamber 21 and then the opening 34 is closed. The blower 22 introduces airflow into the spray chamber 21 and sprays the pollen in the spray chamber 21 onto the female flower through the spray pipe 24 to complete the pollination.
