Description

Technical Field

[0001] The invention relates to the technical field of tea pruning, in particular to a branch pruning machine for tea planting. Background Art

[0002] Tea pruning mainly involves pruning old, weak and diseased branches of tea trees with pruning machines, which can stimulate the growth of tea trees and promote the germination of new shoots. As the tea trees grow, their height and crown width will continue to increase. The crown width is the average width of the tree (seedling) in the north-south and east-west directions. It is used to indicate the specifications of trees and seedlings and to measure their growth. If it is not controlled, tea trees that are too high will make picking difficult, and tea trees that are too crowded will be too large, affecting ventilation and light transmission. Pruning can control the height and crown width of tea trees within an appropriate range.

[0003] There are many types of trimmers on the market, including handheld trimmers, backpack trimmers and some small self-propelled trimmers. Many tea gardens are located in mountainous and hilly areas with complex and changeable terrain. In particular, tea trees on some hillsides have large slopes, and self-propelled trimmers cannot travel normally in tea fields with large slopes. They are prone to rollover or inability to climb, resulting in the inability to effectively trim the tea trees. Because of the current mechanized tea picking, the tea trees need to be trimmed flat for subsequent mechanized tea picking. In some tea fields on hillsides, when pruning tea trees, the pruning equipment cannot remain stable, resulting in uneven pruning of the tea trees, which in turn affects the subsequent mechanized tea picking and the efficiency of mechanized tea picking.

The two reciprocating frames 49 are composed of two L-shaped rods and a slot rod. The reciprocating rod 48 slides inside the slot rod of the reciprocating frame 49. The slot length of the slot rod of the reciprocating frame 49 is adapted to the diameter of the rotation range of the reciprocating rod 48. A fixed frame 410 is fixedly connected to the middle of the slot rod of the reciprocating frame 49. A rotating hole is provided at the bottom of the fixed frame 410. A rotating block 411 is rotatably connected inside the rotating hole of the fixed frame 410.

[0019] like Figure 3 and Figure 4 As shown, the reciprocating frame 49 is provided with a sweeping assembly for sweeping away pruned branches on the tea tree, and the sweeping assembly includes a sweeping rod 51 rotatably connected to an L-shaped rod on one side of the reciprocating frame 49 close to the push rod frame 31, and a plurality of sweeping claws 52 arranged in a linear array are fixedly connected to the lower surface of the sweeping rod 51 at one end away from the reciprocating frame 49.

[0020] like Figure 1 , Figures 7 to 11As shown, a hole is provided on the rotating shaft of each roller 3, and a toggle assembly for sweeping away branches and trunks fallen on the ground is provided on the roller 3. The toggle assembly includes four connecting shafts 61 rotatably connected to the rotating shaft holes of each roller 3, two connecting shafts 61 on the same side are fixedly connected to two connecting rods 62 at both ends, and the middle part of the connecting rod 62 is set as a telescopic structure, and a fixed shaft 63 is fixedly connected between the two ends of the two connecting rods 62. A resistance sleeve 64 corresponding to the position of the roller 3 is rotatably connected to the fixed shaft 63, and the resistance sleeve 64 and the roller 3 are in conflict with each other. The outer surface of the resistance sleeve 64 is set to be made of rubber material, which is used to increase the friction force when the resistance sleeve 64 conflicts with the roller 3, so as to ensure that the resistance sleeve 64 can be effectively driven to rotate during the rotation of the roller 3. A bevel gear 65 is fixedly connected to the end of the resistance sleeve 64 close to the side of the electric telescopic rod 2, and a rotating shaft 66 is rotatably connected to the fixed shaft 63. A through hole for the rotating shaft 66 to rotate is provided on the fixed shaft 63. The outer surface of the movable shaft 66 located below the fixed shaft 63 is fixedly connected with a bevel gear 2 67, and the bevel gear 2 67 is meshed with the bevel gear 1 65. The outer surface of the rotating shaft 66 located below the bevel gear 2 67 is fixedly connected with a half gear 68. The outer surface of the fixed shaft 63 is fixedly connected with a fixed seat 69 corresponding to the position of the rotating shaft 66. The fixed seat 69 is rotatably connected with a swing shaft 610, and a rotation limiting hole for limiting the swing shaft 610 is provided on the swing shaft 610. A torsion spring 611 is sleeved on the outer surface of the swing shaft 610 located above the fixed seat 69, and the two ends of the torsion spring 611 are respectively fixedly connected to the upper surface of the fixed seat 69 and the top of the swing shaft 610. A swing rod 612 is fixedly connected to the bottom of the swing shaft 610. A tooth groove is provided on the side of the swing rod 612 close to the half gear 68, and the tooth grooves of the half gear 68 and the swing rod 612 are meshed with each other. The lower surface of the swing rod 612 is fixedly connected with swing claws 613 arranged in a linear array.

[0021] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: the torsion spring 611 is not deformed and tightened, and at this time, the swing rod 612 is in a parallel state with the connecting rod 62.

[0022] The working state is: the user holds the handle 32, pushes the handle 32 and the push rod frame 31 to make the roller 3 roll on the ground, and the rolling of the roller 3 on the ground makes the electric telescopic rod 2 move to the end position of a row of tea trees. At this time, the electric telescopic rod 2 is located on both sides of the end tea trees. The main frame 1 will be different due to the terrain of the tea field. If the tea field is located on the slope of the hillside, the telescopic axis of the electric telescopic rod 2 can be controlled to extend, so that the telescopic axis of the electric telescopic rod 2 located on the side below the ramp can be extended, and then the main frame 1 can be adjusted to a horizontal state, so that the tea trees in tea fields with different terrains can be subsequently pruned, thereby improving the adaptability of the equipment, so that mechanized or manual picking can be carried out in the subsequent time, and the efficiency of subsequent tea picking can be improved.

[0023] Then the staff slides the convex strips on both sides of the mounting plate 41 into the interior of the mounting groove 11, and then the entire pruning assembly can be installed on the main frame 1. By sliding and inserting, the opening direction of the mounting groove 11 is the side away from the handle 32, that is, the opening direction of the mounting groove 11 is toward the movement direction of the device. When the device is pushed to travel, it will not fall off, thereby achieving a quick installation effect. If the tea tree pruning is completed later, the mounting plate 41 can also be slid out of the mounting groove 11 at this time, thereby achieving a quick disassembly operation, which is convenient for maintenance. At the same time, the weight of the entire equipment can be reduced by disassembly during transportation, so as to facilitate transportation operations. In addition, after disassembly, it can avoid the equipment from tilting and collapsing when walking on a sloping terrain, resulting in collision damage to the equipment, thereby increasing the service life of the equipment.

[0024] The pruning assembly prunes the branches of the tea tree: at this time, the staff can start the motor 46, the output shaft of the motor 46 drives the rotating rod 47 to rotate, and the rotating rod 47 drives the reciprocating rod 48 to rotate. During the rotation of the reciprocating rod 48, the reciprocating rod 48 slides in the slot of the reciprocating frame 49, and the reciprocating rod 48 drives the reciprocating frame 49 to slide on the guide rod 44. During the reciprocating motion of the reciprocating frame 49, the rotating block 411 is driven to reciprocate synchronously through the fixed frame 410. At this time, the rotating block 411 drives the convex tooth 412 The convex teeth 412 synchronously reciprocate inside the tooth groove frame 45. During the movement of the convex teeth 412, the rotating block 411 is driven to rotate in the rotating hole of the fixed frame 410 through the meshing of the teeth of the tooth groove frame 45. The rotating block 411 drives the knife disc 413 to rotate synchronously. The branches of the tea tree can be pruned by the rotation of the knife disc 413. The main frame 1 is kept in a horizontal state, and the knife disc 413 can horizontally pruned the bottom of the tea tree, so that the top of the tea tree remains horizontal and flat, which is convenient for subsequent mechanical picking.

[0025] At this time, the staff pushes the push rod frame 31 by holding the handle 32, so that the roller 3 rolls on the ground, and then the electric telescopic rod 2 moves on both sides of the tea tree to the side away from the push rod frame 31. The electric telescopic rod 2 drives the pruning component slidably installed in the installation groove 11 to move synchronously through the main frame 1. At this time, the reciprocating knife disc 413 will move on the top of the tea tree, thereby realizing the pruning of the branches of a row of tea trees.

[0026] It should be noted that the tea trees pruned by this device are only low shrub-type tea trees, which are generally 1.5-2 meters high.

[0027] The sweeping component sweeps the branches piled on the top of the tea tree: during the reciprocating motion of the reciprocating frame 49, the reciprocating frame 49 will drive the sweeping rod 51 to reciprocate synchronously, and the sweeping rod 51 will drive the sweeping claw 52 to move back and forth above the tea tree that has been rotated and pruned by the blade disc 413, so that the branches piled on the tea tree after pruning can be swept to the ground, which can maintain the continuity of the pruning work. The pruning workers do not need to clean the broken branches on the tea tree after completing the pruning, saving time and labor costs.

[0028] The toggle assembly toggles the branches that fall on both sides of the tea tree apart: in the process of the roller 3 rolling on the ground, the connecting shaft 61 rotates in the rotating shaft hole of the roller 3. In addition, the two connecting rods 62 are used to stabilize the fixed shaft 63, and the connecting rod 62 will not rotate due to the rolling of the roller 3. The roller 3 will drive the conflicting sleeve 64 that conflicts with it to rotate on the fixed shaft 63, and the conflicting sleeve 64 will drive the bevel gear 1 65 to rotate, and the bevel gear 1 65 will drive the bevel gear 2 67 to rotate, and the bevel gear 2 67 will drive the rotating shaft 66 to rotate in the through hole of the fixed shaft 63, and the rotating shaft 66 will drive the half gear 68 to rotate synchronously, and the half gear 68 will drive the swing rod 612 to swing close to the inner side of the four electric telescopic rods 2 through the tooth groove of the swing rod 612, and the swing rod 612 drives the swing shaft 610 to rotate in the limiting hole on the fixed seat 69, and the swing shaft 610 will cause the torsion spring 611 to deform and tighten during the rotation process. The branches fallen on the ground will be moved to the roots of the tea trees through the swing claws 613. When the swing claws 613 on the side away from the push rod frame 31 move the branches, the branches that block the rolling direction of the roller 3 can be swept away to prevent the branches from affecting the rolling of the roller 3 on the ground, so that the staff can push the equipment to move with less effort. In addition, it can also prevent the roller 3 from pressing on the branches and causing the equipment to tilt. Further, it can prevent the problem of uneven pruning of the tea trees due to the tilt of the equipment. When the swing claws 613 on the side close to the push rod frame 31 move the branches, it can reduce the subsequent steps of manual cleaning after pruning is completed. Moving the branches to the roots of the tea trees can also act as natural fertilizers. After the tea branches rot, the organic matter they contain will decompose into nutrients to provide natural organic fertilizers for the tea trees. In addition, the sunlight can be blocked by covering the branches, thereby achieving the effect of inhibiting the growth of weeds.

[0029] When the teeth of the half gear 68 rotate to the point where they are no longer engaged with the tooth grooves of the swing rod 612, under the elastic restoring action of the torsion spring 611, the torsion spring 611 drives the swing shaft 610 to rotate in the opposite direction in the limiting hole of the fixed seat 69, and the swing shaft 610 drives the swing rod 612 to swing in the opposite direction, and then the swing rod 612 returns to a state parallel to the connecting rod 62.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
