Description

Technical Field

[0001] The invention belongs to the technical field of plant planting, in particular to a pruning structure and method for citrus planting. Background Art

[0002] Citrus tree pruning is a technical measure to cut off part of the nutritional organs of fruit trees in order to adjust the crown structure and renew the branch composition. The regulatory effect of mechanical pruning on the growth and development of organs such as branches, leaves, and fruits is related to the change of apical dominance. Since the direction of cytokinin produced by the root system is opposite to the direction of gravity, the more upright the branches and the higher the buds, the more they get, so the faster the cell division and the more vigorous the growth, while the germination and growth of the buds below the apical buds are inhibited. Once the branches are cut, the apical dominance is transferred to the cut buds, and the growth potential of the buds below them is weakened successively, and even cannot germinate and become latent buds, thereby changing the original germination rate and branching ability.

[0003] Since manual pruning of large areas of citrus trees is inefficient, mechanical devices are generally used to replace manual pruning. When the machine is pruning the branches, the fallen branches and leaves will fall onto the mechanical arm that controls the scissors. When working continuously, the mechanical arm is prone to accumulate a large number of branches and leaves, which will make the force arm that controls the scissors unable to work normally, so improvements are needed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: a pruning structure for citrus planting, comprising a suspension device, the bottom of the suspension device is rotatably connected to a bidirectional rotating shaft through a special rotating sleeve, and the front and rear ends of the bidirectional rotating shaft are symmetrically provided with lateral shearing devices;

[0005] The suspension device includes a suspension top plate, which is installed on a preset slide rail above, and the lower surface of the suspension top plate is evenly provided with guide slide bars, and the outer surface of the guide slide bars is slidably connected to a control top seat, and the control top seat can perform directional sliding movement along the guide slide bars, and the left and right sides of the outer surface of the control top seat are symmetrically provided with adjustment connecting plates, and the bottom end of the adjustment connecting plates is fixedly connected to a control motor, and the outer surface of the output shaft of the control motor is fixedly connected to an active rotating wheel, and the lower surface of the control top seat is evenly provided with extension plug plates, and the bottom of the inner cavity of the extension plug plates is evenly provided with auxiliary rolling balls, and because the auxiliary rolling balls are embedded in the bottom of the inner cavity of the extension plug plates, the auxiliary rolling balls can roll relative to the extension plug plates;

[0006] The bidirectional rotating shaft includes a long tube shell, a pressurizing sleeve is fixedly connected to the middle of the inner wall of the long tube shell, extension slide bars are symmetrically arranged on the front and rear sides of the inner wall of the long tube shell, and a compression outer cushion tube is sleeved on the outer surface of the extension slide bar. The compression outer cushion tube can ensure the air tightness inside the long tube shell, and isolation layers are symmetrically opened on both sides of the inner cavity of the long tube shell. After the pressurizing sleeve pressurizes the isolation layers on both sides, the extension slide bar will slide out of the interior of the long tube shell by a proportional length due to the action of air pressure.

[0007] Furthermore, the special rotating sleeve includes a circular sleeve, the outer surface of the circular sleeve is evenly provided with matching grooves, the inner cavity of the circular sleeve is evenly provided with sliding grooves, the bottom end of the extension plug is slidingly connected with the inner cavity of the circular sleeve through the sliding groove, the outer surface of the auxiliary ball is rollingly connected with the inner cavity of the circular sleeve through the sliding groove, the auxiliary ball is embedded in the deepest part of the sliding groove, and the extension plug only needs to provide upward traction for the special rotating sleeve through the auxiliary ball. The number of the control motors is four, the outer surface of the active wheel is meshed and connected with the outer surface of the circular sleeve through the matching groove, the inner wall of the circular sleeve is fixedly connected with the middle part of the outer surface of the long tube shell, and the inner cavity of the long tube shell is symmetrically provided with drainage openings on both sides close to the isolation layer.

[0008] Furthermore, the lateral shearing equipment includes an insulating box shell, a two-way pressure pump is fixedly connected to the middle of the inner wall of the insulating box shell, sliding push rods are symmetrically arranged at both ends of the output shaft of the two-way pressure pump, and vibration components are symmetrically arranged on both sides of the inner wall of the insulating box shell, and one end of the sliding push rod away from the two-way pressure pump is fixedly connected to a control turntable, and a rotary saw frame is fixedly connected to the middle of the outer surface of the control turntable, and a cutting saw blade is rotatably connected to the inner wall of the rotary saw frame. The rotary saw frame cuts off the branches of the citrus tree by controlling the cutting saw blade to rotate at a high speed, thereby achieving trimming work.

[0009] Furthermore, a protective washer is sleeved on the side of the outer surface of the sliding push rod away from the bidirectional pressure pump, one end of the protective washer is rotatably connected to the outer surface of the control dial through a rotation groove, and the other end of the protective washer is rotatably connected to the outer surface of the heat-insulating box shell through the rotation groove. The number of the heat-insulating box shells is two, the number of the cutting saw blades is four, the back of the outer surface of the heat-insulating box shell is fixedly connected to the end of the extension sliding rod away from the pressure sleeve, and the outer surface of the sliding push rod is rotatably connected to the middle of the inner cavity of the heat-insulating box shell through a through hole.

[0010] Furthermore, the vibration-adding component includes a balancing block. The balancing blocks on both sides can increase the weight of the two sides of the heat-insulating box shell. When the heat-insulating box shell rotates, a larger centrifugal force can be generated on both sides. A connecting sleeve is slidably connected at the center of the upper surface of the balancing block. A buffer spring is fixedly connected to the bottom of the outer surface of the connecting sleeve. The end of the buffer spring away from the connecting sleeve is fixedly connected to a pressure-sensitive plate. The top of the inner wall of the connecting sleeve is fixedly connected to the end of the sliding push rod close to the two-way pressure pump. The bottom end of the connecting sleeve is slidably connected to the inner wall of the balancing block through an auxiliary roller rod. The outer surface of the pressure-sensitive plate is fixedly connected to the inner wall of the balancing block. The outer surface of the balancing block is fixedly connected to the inner wall of the heat-insulating box shell.

[0011] First, set up a track to guide the sliding of the pruning structure, and the track is located between adjacent orange trees. Then, install the suspension equipment on the track so that the suspended top plate can slide along the track in a certain direction. After completing the preparation work, push the extended sliding bars on both sides to control the movement of the lateral shearing equipment. Then, the lateral shearing equipment uses the cutting saw blades on both sides to prune the orange trees on both sides of the track. After pruning for a period of time, the active wheel twists the special rotating sleeve to flip the bidirectional rotating shaft and the lateral shearing equipment as a whole, and throw away the branches and leaves on the outer surface. After pruning the orange trees at the corresponding position, the suspended top plate continues to move to prune the next orange tree.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device can perform branch pruning on the orange trees on both sides of the slide rail through the lateral shearing devices on both sides. When the machine is pruning branches, the fallen branches and leaves will fall onto the two-way rotating shaft and the lateral shearing device that control the scissors. If not processed, the accumulated branches and leaves will seriously interfere with the normal pruning work of the device. Therefore, the two-way rotating shaft of the device is set to a flippable structure. When working, by flipping the two-way rotating shaft, the debris accumulated on the outer surface can be thrown out and fall to the ground, thereby eliminating the adverse interference problem of branches falling after pruning.

[0014] 2. The device is connected with a special rotating sleeve through an auxiliary rolling ball at the bottom of the extended plug plate. In order to reduce the resistance of the two-way rotating shaft when turning over, the auxiliary rolling ball is embedded in the bottom of the extended plug plate, and the auxiliary rolling ball can rotate freely relative to the extended plug plate through the rotating groove, so that the rolling friction between the auxiliary rolling ball and the circular sleeve wheel replaces the dynamic friction generated by the extended plug plate and the circular sleeve wheel, thereby achieving the effect of reducing friction resistance, reducing the wear problem of the circular sleeve wheel when rotating, and making the rotation of the two-way rotating shaft smoother.

[0015] 3. The cutting saw blade used for directly pruning branches can rotate around the axis under the control of the control turntable, and can also further fit in the direction of the branch under the propulsion control of the sliding push rod, thereby increasing the freedom of the cutting saw blade. Compared with the method of setting a controllable rotating joint at the cutting saw blade, the torque action of the control turntable and the propulsion action of the sliding push rod of this device have stronger anti-interference capabilities. The protective washer can prevent the detached branches from being entangled on the rotating shaft of the control turntable, preventing the sliding push rod from being unable to slide due to the entanglement of the branches.

[0016] 4. During the sliding movement of the sliding push rod, the sliding push rod will drive the connecting sleeve on the corresponding side to slide along the inner wall of the balance block, so the internal buffer spring will more or less have a certain elastic potential energy due to the extrusion force. After the work is completed, the sliding push rod and the cutting saw blade are driven to perform reciprocating rebound movement in the horizontal direction through the rebound effect of the buffer spring and the protective gasket, thereby shaking off the wood chips and residues on the outer surface. Since the pressure-sensitive plate can feedback the actual advancement length of the connecting sleeve according to the pressure of the buffer spring, the pressurization effect of the two-way pressure pump is limited to prevent the two-way pressure pump from pushing the sliding push rod for a long distance, causing the cutting saw blade to accidentally damage the main stem of the orange tree.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a pruning structure for citrus planting, comprising a suspension device 1, the bottom of the suspension device 1 is rotatably connected to a bidirectional rotating shaft 2 through a special rotating sleeve 3, and lateral shearing devices 4 are symmetrically arranged at the front and rear ends of the bidirectional rotating shaft 2;

[0028] The suspension device 1 includes a suspension top plate 11, which is installed on a preset slide rail above. The lower surface of the suspension top plate 11 is evenly provided with a guide slide bar 12, and the outer surface of the guide slide bar 12 is slidably connected with a control top seat 13, and the control top seat 13 can perform directional sliding movement along the guide slide bar 12. Adjustment connecting plates are symmetrically provided on the left and right sides of the outer surface of the control top seat 13, and the bottom end of the adjustment connecting plate is fixedly connected with a control motor 14, and the outer surface of the output shaft of the control motor 14 is fixedly connected with an active wheel 15, and the lower surface of the control top seat 13 is evenly provided with an extension plug plate 16, and the bottom of the inner cavity of the extension plug plate 16 is evenly provided with an auxiliary rolling ball 17. Since the auxiliary rolling ball 17 is embedded in the bottom of the inner cavity of the extension plug plate 16, the auxiliary rolling ball 17 can roll relative to the extension plug plate 16;

[0029] The bidirectional rotating shaft 2 includes a long tube shell 21, a pressurizing sleeve 22 is fixedly connected to the middle of the inner wall of the long tube shell 21, and extension slide rods 25 are symmetrically arranged on the front and rear sides of the inner wall of the long tube shell 21. The outer surface of the extension slide rod 25 is sleeved with a compression outer cushion tube 26. The compression outer cushion tube 26 can ensure the air tightness inside the long tube shell 21. Isolation layers 24 are symmetrically opened on both sides of the inner cavity of the long tube shell 21. After the pressurizing sleeve 22 pressurizes the isolation layers 24 on both sides, the extension slide rod 25 will slide out of the inside of the long tube shell 21 by a proportional length due to the action of air pressure.

[0030] The special rotating sleeve 3 includes a circular sleeve 31, the outer surface of which is evenly provided with matching grooves 32, the inner cavity of which is evenly provided with sliding grooves 33, the bottom end of the extension plug 16 is slidingly connected with the inner cavity of the circular sleeve 31 through the sliding grooves 33, the outer surface of the auxiliary rolling ball 17 is rollingly connected with the inner cavity of the circular sleeve 31 through the sliding grooves 33, the auxiliary rolling ball 17 is embedded in the deepest part of the sliding grooves 33, and the extension plug 16 only needs to provide upward traction for the special rotating sleeve 3 through the auxiliary rolling ball 17. There are four control motors 14, the outer surface of the active rotating wheel 15 is meshedly connected with the outer surface of the circular sleeve 31 through the matching grooves 32, the inner wall of the circular sleeve 31 is fixedly connected with the middle part of the outer surface of the long tube shell 21, and the inner cavity of the long tube shell 21 is symmetrically provided with drainage openings 23 on both sides near the isolation layer 24.

[0031] After the device is set up on a high slide rail, the suspended top plate 11 moves directionally along the slide rail to control the displacement of the device as a whole. When pruning, the suspended top plate 11 engages the slide rail to keep the device relatively fixed. At this time, the control top seat 13 at the bottom slides along the outer surface of the guide slide rod 12 to fine-tune the actual position of the lateral shearing device 4, and then the lateral shearing device 4 is used to trim the branches of the citrus trees on the side.

[0032] When pruning branches, the control motors 14 on both sides will periodically drive the special rotating sleeve 3 to rotate by twisting the active rotating wheel 15, that is, the bidirectional rotating shaft 2 and the lateral shearing devices 4 on both sides are turned over by the special rotating sleeve 3. At this time, the circular sleeve wheel 31 rotates relative to the extension plug plate 16 and the auxiliary rolling ball 17 through the sliding groove 33. Since the auxiliary rolling ball 17 can roll, the friction resistance encountered by the special rotating sleeve 3 during rotation is also small, so the active rotating wheel 15 can control the rotation of the bidirectional rotating shaft 2 more easily.

[0033] When the bidirectional rotating shaft 2 deflects, the branches and leaves that fall on the outer surface of the bidirectional rotating shaft 2 and the outer surface of the lateral shearing device 4 will be thrown off the outer surface of the device due to the rotation, or will fall naturally under the action of their own gravity, thereby effectively removing the branches and leaves accumulated on the outer surface of the device.

[0034] When trimming, the pressurized sleeve 22 in the middle replenishes air through the drainage port 23, and then pressurizes the inside of the isolation layer 24 to push the extension slide bars 25 on both sides outward, thereby pushing the lateral shearing devices 4 on both sides. As the extension slide bar 25 slides outward, the compression outer cushion tube 26 on the outer surface is further compressed, so it becomes increasingly difficult for the extension slide bar 25 to slide, thereby avoiding the problem of the extension slide bar 25 detaching from the long tube shell 21.

[0035] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of embodiment 1, the lateral shearing equipment 4 includes an insulating box shell 41, a two-way pressure pump 42 is fixedly connected to the middle of the inner wall of the insulating box shell 41, sliding push rods 43 are symmetrically arranged at both ends of the output shaft of the two-way pressure pump 42, and vibration components 5 are symmetrically arranged on both sides of the inner wall of the insulating box shell 41. The end of the sliding push rod 43 away from the two-way pressure pump 42 is fixedly connected to a control turntable 45, and the middle of the outer surface of the control turntable 45 is fixedly connected to a rotary saw frame 46. The inner wall of the rotary saw frame 46 is rotatably connected to a cutting saw blade 47. The rotary saw frame 46 cuts off the branches of the citrus tree by controlling the cutting saw blade 47 to rotate at a high speed, thereby realizing the trimming work.

[0036] A protective gasket 44 is sleeved on the side of the outer surface of the sliding push rod 43 away from the bidirectional pressure pump 42, one end of the protective gasket 44 is rotatably connected to the outer surface of the control dial 45 through a rotation groove, and the other end of the protective gasket 44 is rotatably connected to the outer surface of the heat-insulating box shell 41 through the rotation groove. There are two heat-insulating box shells 41, and four cutting saw blades 47. The back of the outer surface of the heat-insulating box shell 41 is fixedly connected to the end of the extension slide rod 25 away from the pressure sleeve 22, and the outer surface of the sliding push rod 43 is rotatably connected to the middle of the inner cavity of the heat-insulating box shell 41 through a through hole.

[0037] The vibration-adding component 5 includes a balancing block 51. The balancing blocks 51 on both sides can increase the weight of both sides of the heat-insulating box shell 41. When the heat-insulating box shell 41 rotates, a large centrifugal force can be generated on both sides. A connecting sleeve 52 is slidably connected at the center of the upper surface of the balancing block 51. A buffer spring 54 is fixedly connected to the bottom of the outer surface of the connecting sleeve 52. A pressure-sensitive plate 55 is fixedly connected to one end of the buffer spring 54 away from the connecting sleeve 52. The top of the inner wall of the connecting sleeve 52 is fixedly connected to one end of the sliding push rod 43 close to the two-way pressure pump 42. The bottom end of the connecting sleeve 52 is slidably connected to the inner wall of the balancing block 51 through the auxiliary roller rod 53. The outer surface of the pressure-sensitive plate 55 is fixedly connected to the inner wall of the balancing block 51. The outer surface of the balancing block 51 is fixedly connected to the inner wall of the heat-insulating box shell 41.

[0038] The heat-insulating box shell 41 controls the sliding push rods 43 on both sides through the two-way pressure pump 42 in the middle, and slides toward the outside of the heat-insulating box shell 41. In order to facilitate the cutting work, the control turntable 45 can rotate with the axis of the sliding push rod 43, thereby driving the cutting saw blade 47 on the saw frame 46 to rotate, and trimming the branches at different angles. When the sliding push rod 43 slides, it will pull the sleeved protective gasket 44. The protective gasket 44 can separate and block the gap between the sliding push rod 43 and the heat-insulating box shell 41 to prevent the cut branches from being entangled here and causing the sliding push rod 43 to be unable to slide.

[0039] During the sliding movement of the sliding push rod 43, the sliding push rod 43 will drive the connecting sleeve 52 on the corresponding side to slide along the inner wall of the balance block 51, so the internal buffer spring 54 will more or less have a certain elastic potential energy due to the extrusion force. After the work is completed, the sliding push rod 43 and the cutting saw blade 47 are driven to perform reciprocating rebound movement in the horizontal direction through the rebound effect of the buffer spring 54 and the protective gasket 44, thereby shaking off the wood chips and residues on the outer surface. Since the pressure-sensitive plate 55 can feedback the actual propulsion length of the connecting sleeve 52 according to the pressure of the buffer spring 54, the pressurization effect of the two-way pressure pump 42 is limited.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
