Description

Technical Field

[0001] This invention relates to the field of fruit tree pruning technology, and in particular to a labor-saving fruit branch pruning shears. Background Technology

[0002] Fruit tree pruning is a technique that involves removing some vegetative organs to adjust the canopy structure and renew the composition of branches, aiming to balance the relationship between fruit tree growth and fruit production. It utilizes methods such as heading back, thinning, and slow release, based on the principles of apical dominance and bud heterogeneity, to regulate canopy light transmittance and branch ratios, addressing problems such as hollow canopy and declining tree vigor.

[0003] However, when pruning fruit branches high up on fruit trees, it is often necessary to use an A-frame ladder to climb up and work. When pruning, one hand needs to hold the pruning shears and the other hand needs to hold the fruit branch to be pruned to prevent the fruit branch from falling off the pruning shears. This pruning method is quite dangerous and time-consuming and laborious.

[0004] In view of this, the present invention proposes a labor-saving fruit branch pruning shear to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a labor-saving fruit branch pruning shear.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A labor-saving fruit pruning shear includes a drive box. A battery box for power supply is located at the bottom of the drive box, and a fixing screw sleeve is located at the bottom of the battery box. Two receiving grooves communicating with the drive box are located on one side of the top. Sliding grooves are formed on the inner walls of both ends of the receiving grooves. Sliding blocks are slidably connected to the inner walls of the sliding grooves, and a common fixing post is fixedly connected to the middle of the two sliding blocks. A connecting spring is fixedly connected between the top of the sliding blocks and the top inner wall of the receiving groove. A drive disc is rotatably connected to the middle of the fixing post, and a branch-clamping plate is fixedly connected to the outer wall of the drive disc. A stop post is fixedly connected to the inner wall of one side of the top of the sliding groove, and the bottom end of the stop post contacts the outer wall of the branch-clamping plate. A hollow cavity is provided inside the drive disc, and a limit and rebound mechanism is provided inside the hollow cavity. A pulling mechanism for pulling each sliding block downwards synchronously is provided in the drive box.

[0007] Furthermore, an extension opening is provided on the other side of the top of the drive box, and an electric push rod is provided below the extension opening. A trimmer is fixedly connected to the telescopic end of the electric push rod, and the top of the trimmer is located in the extension opening.

[0008] Furthermore, the pulling mechanism includes a winding column, which is rotatably connected to the inside of the drive box, and a bevel gear is fixedly connected to the outer wall of the winding column. A fixing plate is provided below the winding column and fixed to the inner wall of the drive box.

[0009] Furthermore, a drive motor is installed on the second fixed plate, and a bevel gear one that meshes with the second bevel gear is fixedly connected to the output shaft end of the drive motor. Multiple pull ropes are fixedly connected to the outer wall of the winding column, and the top end of each pull rope is fixedly connected to the corresponding slider.

[0010] Furthermore, the limiting and rebound mechanism includes a second locking plate, which is fixedly connected to the outer wall of the top of the fixed column, and a first locking plate is provided on one side of the second locking plate, which is fixedly connected to the inner wall of the hollow cavity.

[0017] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0018] Reference Figure 1 , Figure 2 and Figure 5A labor-saving fruit pruning shear includes a drive box 3, a battery box 2 for power supply at the bottom of the drive box 3, and a fixing screw sleeve 1 at the bottom of the battery box 2. Two receiving slots 8 communicating with the drive box 3 are located on one side of the top, and sliding grooves 16 are formed on the inner walls of both ends of the receiving slots 8. Sliding sliders 22 are slidably connected to the inner walls of the sliding grooves 16, and a common fixing post 21 is fixedly connected to the middle of the two sliders 22. A connecting spring 20 is fixedly connected between the top of the sliders 22 and the top inner wall of the receiving slots 8. A drive disc 23 is rotatably connected to the middle of the fixing post 21, and a branch-locking plate 18 is fixedly connected to the outer wall of the drive disc 23. Abutting post 19 is fixedly connected to the inner wall of one side of the top of the groove 16, and the bottom end of the abutting post 19 contacts the outer wall of the branch clamping plate 18. The drive disc 23 has a hollow cavity 25 inside, and the hollow cavity 25 is equipped with a limit and spring mechanism. The drive box 3 is equipped with a pulling mechanism for pulling each slider 22 to move downward synchronously. It can be screwed onto the electric telescopic rod by fixing the spiral sleeve 1. The position and height of the drive box 3 are adjusted by the electric telescopic rod. When pruning fruit branches at high positions, the position of the drive box 3 is adjusted so that the fruit branch to be pruned is close to the top outer wall of the drive box 3 and above the protrusion 7, and then the pulling machine is pulled. When the mechanism is activated, the slider 22 in the receiving groove 8 moves downward along with the fixed post 21. During this process, the contact point between the bottom end of the abutting post 19 and the outer wall of the branch clamping plate 18 changes. As a result, under the action of the limiting and spring-back mechanism, the branch clamping plate 18 swings upward until it is horizontal. At this point, the limiting and spring-back mechanism prevents the branch clamping plate 18 from swinging upward any further. As the slider 22 moves, it moves downward synchronously with the horizontal branch clamping plate 18 until the branch clamping plate 18 contacts the fruit branch above the protrusion 7, thus clamping the fruit branch above the protrusion 7. The outer wall of the branch clamping plate 18 in contact with the fruit branch is serrated. Therefore, it is difficult for the fruit branches to detach from below the branch clamping plate 18, making the pruning of the fruit branches time-saving and labor-saving, and eliminating the need for climbing to work, greatly improving safety; after pruning, the pulling mechanism no longer pulls the slider 22, and under the action of the rebound force of the connecting spring 20, the slider 22 is reset. During this process, the outer wall of the branch clamping plate 18 will contact the bottom end of the abutting column 19, and as the slider 22 continues to move upward, the branch clamping plate 18 will swing downward, so that the entire branch clamping plate 18 enters the receiving groove 8 and is not exposed to the outside, thus making it easier to move other fruit branches through the receiving groove 8 above the drive box 3 and accurately find the fruit branch that needs to be pruned.

[0019] Reference Figure 2 As a further embodiment of the present invention, an extension opening 7 is provided on the other side of the top of the drive box 3, and an electric push rod 5 is provided below the extension opening 7. The telescopic end of the electric push rod 5 is fixedly connected to a pruning shear 6, and the top of the pruning shear 6 is located in the extension opening 7. After the clamping and fixing are completed, the electric push rod 5 causes the pruning shear 6 to extend out of the extension opening 7, thereby cutting off the clamped and fixed fruit branch.

[0020] Reference Figure 2 and Figure 3 As a further embodiment of the present invention, the pulling mechanism includes a winding column 9, which is rotatably connected to the inside of the drive box 3, and a bevel gear 13 is fixedly connected to the outer wall of the winding column 9. A fixing plate 10 fixed to the inner wall of the drive box 3 is provided below the winding column 9.

[0021] Reference Figure 2 and Figure 3 As a further embodiment of the present invention, a drive motor 11 is installed on the fixing plate 2 10, and a bevel gear 12 that meshes with the bevel gear 2 13 is fixedly connected to the output shaft end of the drive motor 11. Multiple pull ropes 17 are fixedly connected to the outer wall of the winding column 9, and the top end of each pull rope 17 is fixedly connected to the corresponding slider 22. The drive motor 11 can make the winding column 9 rotate forward or backward through the meshing bevel gear 12 and bevel gear 2 13, so that the pull ropes 17 are wound on the winding column 9 or the pull ropes 17 wound on the winding column 9 are unwound.

[0022] Reference Figure 6 As a further embodiment of the present invention, the limiting and rebound mechanism includes a second locking plate 26, which is fixedly connected to the top outer wall of the fixed column 21. A first locking plate 24 is provided on one side of the second locking plate 26, which is fixedly connected to the inner wall of the hollow cavity 25. When the locking plate 18 swings upward, the first locking plate 24 will rotate together with the drive disk 23. When the first locking plate 24 contacts the second locking plate 26 above the fixed column 21, the drive disk 23 cannot continue to rotate, and the locking plate 18 is in a horizontal state.

[0023] Reference Figure 6 As a further embodiment of the present invention, a reset plate 27 is provided on the other side of the second locking plate 26, and the reset plate 27 is fixedly connected to the outer wall of the fixed column 21. An arc spring 28 is provided between the first locking plate 24 and the reset plate 27. When the bottom end of the abutting column 19 presses the locking plate 18 downward, the arc spring 28 between the first locking plate 24 and the reset plate 27 is compressed. Thus, when the slider 22 moves downward under the action of the pulling mechanism, the rebound force of the arc spring 28 can make the locking plate 18 swing upward.

[0024] Working principle: The fixed spiral sleeve 1 can be screwed onto the electric telescopic rod. The position and height of the drive box 3 are adjusted by the electric telescopic rod. When pruning fruit branches at a high position, the position of the drive box 3 is adjusted so that the fruit branch to be pruned is close to the top outer wall of the drive box 3 and above the extension 7. Then, the pulling mechanism is activated, causing the slider 22 in the receiving groove 8 to move downward with the fixed column 21. During this process, the contact point between the bottom end of the abutting column 19 and the outer wall of the branch clamping plate 18 changes. As a result, under the action of the limiting and rebounding mechanism, the branch clamping plate 18 will swing upward until it is horizontal. At this time, the limiting and rebounding mechanism prevents the branch clamping plate 18 from swinging upward further. As the slider 22 moves, it will move the horizontal branch clamping plate 18 downward synchronously. The branch clamping plate 18 contacts the fruit branch above the protrusion 7, thus clamping the fruit branch above the protrusion 7. The outer wall of the branch clamping plate 18 in contact with the fruit branch is serrated, making it difficult for the fruit branch to detach from below the branch clamping plate 18. This saves time and effort in pruning the fruit branch and eliminates the need for climbing, greatly improving safety. After pruning, the pulling mechanism stops pulling the slider 22. Under the rebound force of the connecting spring 20, the slider 22 returns to its original position. During this process, the outer wall of the branch clamping plate 18 contacts the bottom end of the abutment post 19. As the slider 22 continues to move upward, the branch clamping plate 18 swings downward, so that the entire branch clamping plate 18 enters the receiving groove 8 and is not exposed. This makes it easier to move other fruit branches through the receiving groove 8 above the drive box 3 and accurately locate the fruit branch that needs to be pruned.

[0025] Reference Figure 1 , Figure 4 As a further embodiment of the present invention, a fixing plate 4 is fixedly connected to the outer wall of the drive box 3, and a cleaning sleeve 15 is installed on the fixing plate 4. The cleaning sleeve 15 is filled with an application sponge 14. Before pruning the high fruit branches, the healing agent is dripped into the cleaning sleeve 15 and absorbed by the application sponge 14. After the high fruit branches are cut off, the position of the drive box 3 is adjusted so that the cut end of the fruit branch is inserted into the cleaning sleeve 15. Then, the cut end of the fruit branch squeezes the application sponge 14, and the healing agent absorbed by the application sponge 14 is squeezed out and applied to the cut end of the fruit branch to prevent the wound of the fruit branch from being infected by bacteria and avoid it from being attacked by pathogens.

[0026] Reference Figure 1 , Figure 7As a further embodiment of the present invention, receiving cavities 29 are provided on both sides of the protrusion 7, and baffles 30 are slidably connected at the connection between the receiving cavity 29 and the protrusion 7. One end of each baffle 30 is in contact with the surface of the trimmer 6, and the other end of each baffle 30 is fixedly connected to a sliding plate 31. A connecting spring 32 is fixedly connected between the sliding plate 31 and the inner wall of the receiving cavity 29. Under the elastic force of the connecting spring 32, one end of the baffle 30 is always in contact with the surface of the trimmer 6, thereby sealing the protrusion 7 and preventing debris such as twigs from entering the drive box 3 through the protrusion 7 during trimming and affecting the pulling mechanism.

[0027] Working principle: Before pruning high fruit branches, the healing agent is dripped into the cleaning sleeve 15. The healing agent is absorbed by the application sponge 14. After the high fruit branch is cut off, the position of the drive box 3 is adjusted so that the cut end of the fruit branch is inserted into the cleaning sleeve 15. Then, the cut end of the fruit branch squeezes the application sponge 14, and the healing agent absorbed by the application sponge 14 is squeezed out, thus applying it to the cut end of the fruit branch to prevent the wound from being infected by bacteria and avoid it from being attacked by pathogens. Under the elastic force of the connecting spring 32, one end of the baffle 30 is always in contact with the surface of the pruning shears 6, thereby sealing the protrusion 7 and preventing debris such as broken branches from entering the drive box 3 through the protrusion 7 during pruning and affecting the pulling mechanism.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
