Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a fruit tree thinning device, including a fixed rod 1, a fixed block 19 at the top of the fixed rod 1, a rotating rod 20 rotatably connected to the fixed block 19 via a bearing, a rotating plate 2 fixedly sleeved on the outer wall of the rotating rod 20, a driving assembly at the rear of the fixed block 19, a frame 3 and a support 5 respectively on the upper and lower sides of the rotating plate 2, a sliding assembly in the inner cavity of the frame 3, a cutting shear 4 on the sliding assembly, and a reciprocating assembly in the inner cavity of the support 5, a saw blade 6 on the reciprocating assembly. The device allows two shear blades 4 to slide simultaneously into the center of the inner cavity of the frame 3, thereby cutting the branches. The reciprocating component allows the saw blade 6 to cut thicker branches. The drive component allows switching between two pruning methods, with the desired pruning method positioned above the fixed rod 1 for easy cutting. This solves the problem that existing fruit and vegetable thinning equipment only has one function of pruning branches, and the shear blades 4 have insufficient cutting ability to shorten thicker branches when pruning thicker fruit trees.

[0025] In the embodiment, the driving assembly comprises a worm wheel 21, a fixing frame 22, a worm 23 and a knob 24. The worm wheel 21 is fixedly sleeved on the outer wall of the rotating rod 20. The fixing frame 22 is arranged at the rear side of the fixing block 19. One end of the worm 23 is rotatably connected to the top end of the inner cavity of the fixing frame 22 through a bearing. The other end of the worm 23 extends to the bottom end of the fixing frame 22 and is fixedly connected with the knob 24. The worm 23 is engaged with the worm wheel 21. Rotating the knob 24 drives the worm 23 to rotate. Since the worm 23 is engaged with the worm wheel 21, when the worm 23 rotates, the worm wheel 21 drives the rotating plate 2 to rotate through the rotating rod 20, so that the support 5 and the rack 3 rotate, and then the cutting mode to be used is above the fixing rod 1, which facilitates cutting. Under the self-locking action between the worm 23 and the worm wheel 21, the device can be prevented from rotating during trimming, and the stability of the device during use is improved.

[0026] In the embodiment, the sliding assembly comprises a first motor 7, a lead screw 8, sliding blocks 9 and a limiting assembly. The first motor 7 is arranged at the left end of the rack 3. The output end of the first motor 7 extends to the inner cavity of the rack 3. One end of the lead screw 8 is rotatably connected to the right side of the inner cavity of the rack 3 through a bearing. The other end of the lead screw 8 is fixedly connected with the output end of the first motor 7. Two sliding blocks 9 are respectively screwed on the outer walls of the left and right sides of the lead screw 8 and are respectively fixedly connected with two cutting knives 4. The limiting assembly is arranged at the bottom end of the inner cavity of the rack 3 and is fixedly connected with the bottom ends of the two sliding blocks 9. Starting the first motor 7 drives the lead screw 8 to rotate, and then the relative screw rotation force of the threads on the left and right sides of the outer wall of the lead screw 8 is generated, so that the two sliding blocks 9 simultaneously slide relative to each other under the limiting action of the limiting grooves 10 and the limiting blocks 11, and the two cutting knives 4 simultaneously slide to the middle part of the inner cavity of the rack 3, so that the two cutting knives 4 can cut the branches.

[0027] In the embodiment, the threads on the left and right sides of the outer wall of the lead screw 8 are arranged oppositely, so that the relative screw rotation force of the left and right sides of the outer wall of the lead screw 8 is generated when the lead screw 8 rotates, and the two sliding blocks 9 simultaneously slide relative to each other under the limiting action of the limiting grooves 10 and the limiting blocks 11.

[0028] In the embodiment, the limiting assembly comprises limiting grooves 10 and limiting blocks 11. The limiting grooves 10 are arranged at the bottom end of the inner cavity of the rack 3. The two limiting blocks 11 are slidably embedded in the inner cavities of the limiting grooves 10 and are respectively fixedly connected with the bottom ends of the two sliding blocks 9. Under the combined action of the limiting grooves 10 and the limiting blocks 11, the sliding blocks 9 can be prevented from rotating with the lead screw 8 when the lead screw 8 rotates, and the stability of the sliding assembly during use is improved.

[0029] The inner cavity of the limiting groove 10 is matched with the outer wall of the limiting block 11, and both are in the shape of T, so that one end of the limiting block 11 is always embedded in the inner cavity of the limiting groove 10, and the stability of the limiting assembly during use is improved.

[0030] In the embodiment, the reciprocating assembly comprises a second motor 12, a rotating column 13, a roller 14, a sliding groove 15, two guide rods 16, a sliding plate 17 and a sliding rod 18. The second motor 12 is arranged at the right end of the support 5, the output end of the second motor 12 extends into the inner cavity of the support 5, one end of the rotating column 13 is rotatably connected to the left side of the inner cavity of the support 5 through a bearing, the other end of the rotating column 13 is fixedly connected with the output end of the second motor 12, the roller 14 is fixedly sleeved on the outer wall of the rotating column 13, the sliding groove 15 is arranged on the outer wall of the roller 14, the two guide rods 16 are arranged in the inner cavity of the support 5, the sliding plate 17 is slidably sleeved on the outer walls of the two guide rods 16, and the sliding rod 18 is slidably embedded in the inner cavity of the sliding groove 15 and fixedly connected with the bottom end of the sliding plate 17. When the second motor 12 is started, the second motor 12 drives the roller 14 and the sliding groove 15 to rotate through the rotating column 13. Since the sliding groove 15 is in the shape of a spiral and is connected at the head and tail, when the sliding groove 15 rotates, the sliding rod 18 drives the sliding plate 17 to reciprocally slide along the horizontal direction left and right under the limiting action of the two guide rods 16, so that the saw blade 6 reciprocally slides left and right, and the cutting of the thick branches can be realized.

[0031] In the embodiment, the sliding groove 15 is in the shape of a spiral and is connected at the head and tail, when the sliding groove 15 rotates, the sliding rod 18 drives the sliding plate 17 to reciprocally slide along the horizontal direction left and right under the limiting action of the two guide rods 16.

[0032] In the embodiment, the saw blade 6 is a steel saw blade 6, which has high strength and long service life.

[0033] In the embodiment, the two cutting knives 4 are provided with knife edges on the sides close to each other.
