[0002] Pruning fruit trees mainly focuses on shortening the bud and shoot segments, which helps to concentrate nutrients and allows the branches to grow better. It is also necessary to appropriately prune the new shoots. Just cut off the tender parts at the top, which is beneficial for the fruit tree to flower and bear fruit. When the branches grow densely, they should be thinned out in time, and the thin and long branches should be cut off; therefore, a device for pruning fruit trees is needed.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1-Figure 3 The present invention provides a fruit tree pruning device with an integral pruning function, comprising:

[0030] The trimming head comprises a mounting plate 1, and a clearance hole 2 is formed on the mounting plate 1;

[0031] The trimming mechanism comprises a first trimming assembly and a second trimming assembly, wherein the first trimming assembly is rotatably connected to the mounting plate 1, the second trimming assembly is slidably connected to the mounting plate 1, and the second trimming assembly is arranged corresponding to the clearance hole 2;

[0032] The driving mechanism includes a support plate 3. The cross-sectional shape of the support plate 3 is U-shaped. A chute 4 is provided on the mounting plate 1 along the length direction. The support plate 3 is slidably connected in the chute 4. A driving component is installed in the chute 4. The end of the driving component is rotatably connected to the support plate 3. The driving component is used to push the support plate 3 to slide. The first trimming component is rotatably connected to the support plate 3, and the second trimming component is fixedly connected to one end of the support plate 3.

[0033] The transmission component is installed on the support plate 3 and is in transmission cooperation with the second trimming component.

[0034] The hand-held bracket 5, and the mounting plate 1 is detachably connected to the hand-held bracket 5.

[0035] Among them, a storage battery 6 and a controller are installed on the hand-held bracket 5. The storage battery 6 is electrically connected to the controller. The transmission component and the driving component are both electrically connected to the controller.

[0036] When the present invention works, the trimming head is installed on the hand-held bracket 5, and the operation of the device is realized through the hand-held bracket 5. When trimming hard branches, the transmission component drives the first trimming mechanism to rotate, and the first trimming mechanism forms a structure similar to a saw to cut the hard branches from the fruit tree. When tender branches need to be trimmed, the tender branches pass through the mounting plate 1 through the让位孔 2 (it should be noted that there may be an error in the original text here, assuming it is a specific hole name). The driving component drives the support plate 3 to slide, thereby driving the second trimming component to move, so as to trim the tender branches. The overall working state is controlled by the controller, and the storage battery 6 provides electrical energy for the transmission component or the driving component, improving the portability of the device.

[0037] The present invention uses the first trimming component to trim the hard branches of fruit trees and the second trimming component to trim the tender branches of fruits, so that a single device can achieve multiple working modes, improving the application range of the device and reducing the complexity of work.

[0038] In a further optimized scheme, the first trimming component includes four groups of connecting rods 7 that are sequentially rotatably connected. The connecting rods 7 are arranged in a quadrilateral structure. Transmission wheels 8 are rotatably connected to the hinge points of adjacent connecting rods 7. Two of the transmission wheels 8 are respectively rotatably connected to the end of the mounting plate 1 away from the hand-held bracket and the top surface of the support plate 3 through rotating shafts. The four transmission wheels 8 are in transmission cooperation through a chain 9. Trimming blades are installed on the outer wall of the chain 9. The transmission wheel 8 rotatably connected to the support plate 3 is in transmission cooperation with the transmission component.

[0039] In a further optimized scheme, the second trimming component includes two symmetrically arranged cutting knives 10. The sides of the two cutting knives 10 close to each other are set as arc surfaces 11. Cutting edges are provided on the arc surfaces 11. The让位孔 2 (assuming it is a specific hole name) is located between the two cutting knives 10. One of the cutting knives 10 is fixedly connected to the end of the mounting plate 1 away from the hand-held bracket 5, and the other cutting knife 10 is fixed to the end of the support plate 3. The cutting knives 10 are located between the transmission wheels 8 and the mounting plate 1.

[0040] The cutting knife 10 in a fixed state is relatively fixed to the mounting plate 1 , and the cutting knife 10 in a sliding state slides relatively to the mounting plate 1 , thereby ensuring sufficient bearing capacity between the two.

[0041] A further optimized solution is that the pushing component includes a fixed block 12 fixedly connected to the bottom surface of the support plate 3, a threaded hole is opened on the fixed block 12, a screw 13 is threadedly connected in the threaded hole, a support seat 14 is fixedly connected in the slide groove 4, the screw 13 is rotatably connected to the support seat 14, one end of the screw 13 is fixedly connected to a transmission motor 15, the transmission motor 15 is fixedly connected to the mounting plate 1, and the transmission motor 15 is electrically connected to the battery 6.

[0042] According to a further optimization scheme, the transmission assembly includes an electric slip ring 16, the stator of the electric slip ring 16 is fixedly connected to the top surface of the support plate 3, the rotor of the electric slip ring 16 is fixedly connected to the rotating shaft of the transmission wheel 8 located on the support plate 3, and the electric slip ring 16 is electrically connected to the battery 6. The electric slip ring 16 is used to drive one of the transmission wheels 8 to rotate, and the transmission wheel 8 directly connected to the electric slip ring 16 drives the chain 9 to transmit. A pruning blade is provided on the chain 9, and the pruning blade is used to form a chain saw structure for pruning hard branches. For tender branches, due to restrictions such as the rotation speed of the cutting blade, some positions need to be sheared. Therefore, a second pruning component is provided, and the support plate 3 is pushed by the pushing component to slide along the slide groove 4. The support plate 3 drives one of the cutting knives 10 and the other cutting knives 10 to form a cutting area. The tender branches extend between the two cutting knives 10 through the clearance groove for cutting. The four groups of connecting rods 7 are symmetrical in pairs and form two symmetrical isosceles triangle structures between the mounting plate 1. When the spacing between the two transmission wheels 8 located on the mounting plate 1 and the support plate 3 is adjusted, the connecting rod 7 drives the other two transmission wheels 8 to change their relative positions, so that the shape of the overall cutting mechanism can be adjusted, which is convenient for the device to work in various working conditions.

[0043] In this embodiment, in actual work, the chain 9 will produce slight deformation after a long period of work, resulting in loose meshing with the transmission wheel 8. Therefore, a sliding sleeve is fixed on the connecting rod 7, and a support rod is slidably connected in the sliding sleeve. The end of the support rod is rotatably connected with a tensioning gear, and the tensioning gear is meshed with the chain 9. At the same time, a compression spring is fixedly connected to the other end of the support rod, and the tension spring is fixedly connected to the connecting rod 7. A limiting structure is used at the end of the sliding sleeve to limit the extension length of the support rod. In this way, the chain 9 can be kept in a taut state by setting the tensioning gear. At the same time, it should be noted that four sets of tensioning components are provided in this embodiment, corresponding to the chains 9 in four directions respectively, forming regional divisions to avoid tooth-playing between the chain 9 and the transmission wheel 8. The transmission wheel 8 adopts a sprocket.

[0044] A further optimized solution is provided on the handheld bracket 5, in which a plug-in slot 17 is fixedly connected a positioning seat 18, one end of the mounting plate 1 is in contact with the positioning seat 18, a side wall of the plug-in slot 17 is provided with a stepped hole 19, in which a positioning assembly is installed, a side surface of the mounting plate 1 is provided with a positioning slot 20, the positioning assembly and the positioning slot 20 are limitedly matched, the battery 6 is installed in the plug-in slot 17, a wiring hole is provided on the side wall of the mounting slot, and the wires of the battery 6 extend out of the plug-in slot 17 through the wiring hole.

[0045] The wires of the battery 6 pass through the wiring hole and are connected to the wiring port. The wires of the electric slip ring 16 and the transmission motor 15 are guided by the threading groove opened on the mounting plate 1 and connected to the wiring head at the end. The connection between the two is achieved through the setting of the wiring port and the wiring head. In this way, the battery 6 can be replaced when the battery power is low, and there is no need to use cable connection, thereby improving the portability of the device.

[0046] Further optimization scheme, the positioning assembly includes a positioning rod 21 slidably connected in the stepped hole 19, one end of the positioning rod 21 is limitedly matched with the positioning groove 20, a spring 22 is sleeved on the positioning rod 21, one end of the spring 22 is fixedly connected to the inner wall of the positioning rod 21, the other end of the spring 22 is fixedly connected to the inner wall of the stepped hole 19, and a stopper 23 is fixedly connected to one end of the positioning rod 21 away from the positioning groove 20. The mounting plate 1 is detachable from the hand-held bracket 5 at the bottom, so that when pruning branches at a higher position, the longer hand-held bracket 5 can be directly replaced to improve the application range of the device.

[0047] In a further optimized solution, the two sides of the slide 4 are provided with card slots, and the outer walls of the two sides of the support plate 3 are fixedly connected with card blocks, which are slidably connected in the card slots. The length of the card slots is less than the length of the slide 4, and a blockage is formed at both ends, so that the travel of the support block can be limited.

[0048] As a further optimization solution, the outer wall of the handheld bracket 5 is provided with anti-slip grooves.

[0049] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0050] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
