Description

Technical Field

[0001] This utility model relates to the field of kiwifruit cultivation technology, and in particular to a shaping and pruning device for kiwifruit cultivation. Background Technology

[0002] In kiwifruit cultivation, pruning is crucial for plant growth and fruit quality. Vigorous branch growth, if not pruned in time, leads to poor ventilation and light penetration, excessive nutrient consumption, and negatively impacts fruit yield and quality. Traditional manual pruning is labor-intensive, inefficient, and its accuracy is dependent on experience, making it unsuitable for large-scale cultivation. Therefore, there is an urgent need for pruning devices that can reduce labor intensity and improve efficiency and accuracy.

[0003] Patent CN208956488U discloses a pruning and shaping device for kiwifruit cultivation, including a base with a bottom plate welded to its bottom. Four casters are connected to the four corners of the bottom of the bottom plate. A slide rail is connected along the height direction inside the base, and the rear wall of the rack is slidably connected to the slide rail. This invention allows for flexible adjustment of the pruning shears height via a first electric telescopic rod, facilitating the removal of tall branches. The casters facilitate movement, and the rack and pinion mechanism, along with the slide rail, ensures stable operation.

[0004] While existing pruning and shaping devices for kiwifruit cultivation can control the height of the pruning shears by activating the first electric telescopic rod, making it easier and more efficient to prune higher branches, they face several prominent problems in practical use. In terms of operation, while extending the handle increases the operating range, there is no mention of anti-slip design or angle adjustment function. Prolonged gripping may lead to operator hand fatigue, and the flexibility of operation is limited when dealing with branches at different angles. Furthermore, the base only relies on casters for movement, which, while flexible, lacks a braking mechanism. Therefore, to address these shortcomings of existing technology, we urgently need an innovative pruning and shaping device for kiwifruit cultivation to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a shaping and pruning device for kiwi fruit cultivation, which solves the problem that although the extended handle can extend the operating range, it does not mention anti-slip design or angle adjustment function, and long-term holding may cause hand fatigue for operators.

[0006] To achieve the above objectives, this utility model provides a shaping and pruning device for kiwifruit cultivation, including a transfer component;

[0007] It also includes the chassis in the transfer assembly, and a cutting assembly is installed on top of the chassis;

[0008] The cutting assembly includes two upright plates, each positioned corresponding to the other. Each upright plate has a side opening on its side surface. A rotating shaft is rotatably connected to the inner wall of each side opening. A mounting base is fixedly connected to the side surface of the rotating shaft. A connecting rod is fixedly connected to the side surface of the mounting base. An extension rod is fixedly connected to the outer end of the connecting rod. A mounting cylinder is fixedly connected to the outer section of the extension rod. A motor is fixedly connected to the inner wall of the mounting cylinder. A cutting tool is fixedly connected to the output shaft of the motor. A second electric telescopic rod is fixedly connected to the bottom side surface of the extension rod. An inclined plate is fixedly connected to the end of the second electric telescopic rod. The lower surface of the inclined plate is fixedly connected to the upper surface of the chassis. The lower surfaces of both upright plates are fixedly connected to the upper surface of the chassis.

[0009] The inclined plate has a semi-enclosed shell fixedly connected to its side surface. The side surface of the semi-enclosed shell has an opening for movement. The upper surface of the semi-enclosed shell has a small block fixedly connected to it. There are two small blocks in corresponding positions. The small blocks have a rotating rod that moves through them. The side surface of the mounting cylinder has a circular protective side plate fixedly connected to it.

[0010] The rotating rod has a movable protective plate fixedly connected to its side surface, the lower surface of the movable protective plate is movably connected to the upper surface of the semi-enclosed shell, the lower surface of the movable protective plate is movably connected to the side surface of the extension rod, and large protective side plates are fixedly connected to both sides of the semi-enclosed shell.

[0011] The chassis has four support legs fixedly connected to its lower surface. The support legs are evenly distributed at the four corners of the chassis lower surface, and each pair of adjacent support legs is fixedly connected to a mounting plate.

[0012] The two mounting plates each have mounting holes on their upper surfaces. The inner walls of the two mounting holes are fixedly connected to first electric telescopic rods. The output ends of the two first electric telescopic rods are fixedly connected to positioning cones. The side surfaces of the two mounting plates are fixedly connected to long protective plates. The top ends of the two first electric telescopic rods are fixedly connected to protective top plates. The side surfaces of the protective top plates are fixedly connected to the side surfaces of the chassis.

[0013] The support leg is fixedly connected to a wheel at its bottom end, and a reinforcing rod is fixedly connected between the two support legs on the same side. There are two reinforcing rods in corresponding positions. A push rod is fixedly connected to one side surface of the chassis, and a crossbar is fixedly connected to the top of the push rod.

[0014] This invention relates to a pruning and shaping device for kiwifruit cultivation. In this device, a base supports a cutting assembly above. Rotating shafts connected to the side openings of two upright plates are linked to mounting blocks. A motor inside a mounting cylinder on the outer end of an extension rod drives the cutting blade. The extension rod is connected to the base via a second electric telescopic rod. During operation, the extension and retraction of the second electric telescopic rod causes the extension rod to rotate around the rotating shaft, adjusting the cutting angle and height, while the motor drives the cutting blade to cut. This structure can flexibly adapt to different branches, reducing manual labor and improving efficiency and flexibility. Attached Figure Description

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1-5 A pruning and shaping device for kiwifruit cultivation includes a transfer component 1.

[0024] It also includes the chassis 101 in the transfer component 1, and the cutting component 2 is provided on the chassis 101;

[0025] The cutting assembly 2 includes two upright plates 206, which are positioned correspondingly. Each upright plate 206 has a side hole 207 on its side surface. A rotating shaft 208 is rotatably connected to the inner wall of the side hole 207. A mounting base 209 is fixedly connected to the side surface of the rotating shaft 208. A connecting rod 210 is fixedly connected to the side surface of the mounting base 209. An extension rod 211 is fixedly connected to the outer end of the connecting rod 210. A mounting cylinder 212 is fixedly connected to the outer section of the extension rod 211. A motor 214 is fixedly connected to the inner wall of the mounting cylinder 212. A cutting tool 215 is fixedly connected to the output shaft of the motor 214. A second electric telescopic rod 216 is fixedly connected to the bottom side surface of the extension rod 211. An inclined plate 217 is fixedly connected to the end of the second electric telescopic rod 216. The lower surface of the inclined plate 217 is fixedly connected to the upper surface of the chassis 101. The lower surfaces of both upright plates 206 are fixedly connected to the upper surface of the chassis 101.

[0026] The chassis 101 of the transfer assembly 1 provides an installation base for the cutting assembly 2. The upright plates 206 at two corresponding positions in the cutting assembly 2 support the rotating shaft 208 through the side holes 207. The rotating shaft 208 is fixed to the mounting base block 209. The mounting base block 209 is connected to the extension rod 211 via the connecting rod 210. The motor 214 is fixed inside the mounting cylinder 212 of the outer section of the extension rod 211. The output shaft of the motor 214 drives the cutting tool 215 to rotate to achieve the cutting action. The second electric telescopic rod 216 at the bottom of the extension rod 211 is fixed to the chassis 101 through the inclined plate 217. When the second electric telescopic rod 216 extends or retracts, it can drive the extension rod 211 to rotate around the rotating shaft 208 as the fulcrum, thereby adjusting the angle and height of the cutting tool 215 to adapt to the pruning needs of branches at different positions.

[0027] Furthermore, the semi-encased shell 201 on the side surface of the inclined plate 217 is positioned by a fixed connection, and the movable opening 202 on its side surface provides clearance for the movement of related components; the two small blocks 203 on the upper surface of the semi-encased shell 201 support the rotating rod 204, allowing the rotating rod 204 to move within the small blocks 203; the circular protective side plate 213 on the side surface of the mounting cylinder 212 can protect the mounting cylinder 212 and the internal motor 214, reducing the direct impact of debris generated during the trimming process on the motor 214.

[0028] Furthermore, the rotating rod 204 is fixedly connected to the movable protective plate 205. When the rotating rod 204 rotates within the small block 203, it drives the movable protective plate 205 to move synchronously. The lower surface of the movable protective plate 205 is movably connected to the semi-encased shell 201 and the extension rod 211, so that the movable protective plate 205 can adjust its posture with the rotation of the extension rod 211, always effectively shielding the cutting area. The large protective side plates 218 on both sides of the semi-encased shell 201 extend the protection range from the side, and cooperate with the movable protective plate 205 and the semi-encased shell 201 to block the debris generated during trimming, thereby improving operational safety.

[0029] Furthermore, the four support legs 102 on the lower surface of the chassis 101 are evenly distributed at the four corners, jointly bearing the overall weight of the device and keeping the chassis 101 stable; the mounting plate 106 between adjacent support legs 102 connects the support legs 102 into a whole, enhancing the structural strength of the support legs 102, improving the overall stability of the device, and preventing shaking during movement or operation.

[0030] Furthermore, the mounting hole 107 on the mounting plate 106 provides an installation position for the first electric telescopic rod 108, allowing the first electric telescopic rod 108 to be stably fixed. When a fixing device is required, the first electric telescopic rod 108 extends, pushing the positioning cone 111 at its output end into the ground, thereby fixing the device in the designated position and preventing the device from moving during operation. The long strip protective plate 109 on the side surface of the mounting plate 106 and the protective top plate 110 at the top of the first electric telescopic rod 108 protect the first electric telescopic rod 108 from the side and top, respectively, reducing damage caused by external factors.

[0031] Furthermore, the wheels 112 at the bottom of the support legs 102 facilitate the overall movement of the device. The operator can easily move the device by pushing the push rod 104 on one side of the chassis 101 and the crossbar 105 at the top. The two reinforcing rods 103 between the two support legs 102 on the same side enhance the connection strength of the support legs 102, improve the load-bearing capacity and stability of the support legs 102, and ensure that the device is structurally stable during movement and operation.

[0032] The complete working process is as follows: First, the operator moves the device to the kiwi fruit planting area by pushing the push rod 104 on one side of the chassis 101 and the crossbar 105 at the top, using the wheels 112 at the bottom of the support legs 102. The reinforcing rod 103 between the two support legs 102 on the same side ensures the stability of the device structure during movement. After reaching the working position, the first electric telescopic rod 108 in the mounting hole 107 on the mounting plate 106 is activated, causing the positioning cone 111 at its output end to extend and insert into the ground, fixing the device and preventing movement during operation. At this time, the long protective plate 109 and the protective top plate 110 protect the first electric telescopic rod 108. Next, the motor 214 installed on the inner wall of the cylinder 212 in the cutting assembly 2 is activated. The output shaft of the motor 214 drives the cutting blade 215 to rotate, preparing for the pruning operation. Based on the position of the branch to be pruned, the extension rod 211 is extended and retracted by controlling the second electric telescopic rod 216 at the bottom of the extension rod 211, which drives the extension rod 211 to rotate around the rotating shaft 208 as the fulcrum. The rotating shaft 208 rotates in the side hole 207 of the upright plate 206, and the mounting block 209 moves synchronously with the rotating shaft 208. The connecting rod 210 connects the mounting block 209 and the extension rod 211, thereby adjusting the angle and height of the cutting blade 215 to align with the branch to be pruned. During the operation of the cutting tool 215, the semi-encased shell 201 on the side surface of the inclined plate 217 and the movable protective plate 205 driven by the rotating rod 204 move within the small block 203. The movable protective plate 205, together with the semi-encased shell 201, the extension rod 211, and the large protective side plates 218 on both sides of the semi-encased shell 201, work together to block the debris generated during trimming. The circular protective side plate 213 on the side surface of the mounting cylinder 212 protects the internal motor 214. The movable opening 202 of the semi-encased shell 201 provides space for the movement of related components. After trimming is completed, the motor 214 is turned off to stop the cutting tool 215 from rotating, the second electric telescopic rod 216 is reset, and the first electric telescopic rod 108 is activated to lift the positioning cone 111 off the ground, allowing the device to move to the next working position.
