Description

Trunk tiller remover

Technical Field

The application relates to the technical field of garden tools, in particular to a trunk tiller remover.

Background

Tillering is intended to mean the regenerated branches of a tree that has been cut or fallen down, and to be extended to bud-bearing rice. Three modes of tiller removal, cutting and thinning are commonly adopted for tree pruning in gardens.

In winter, the tillering of the tree is removed, and the tender branches growing at the base of the trunk and near the wound in the current year or the root sets growing at the root are removed. The influence of the branches and the root sets on the tree form is avoided, and the nutrients of the tree are dispersed.

Pruning scissors are commonly used for pruning trees in gardens, the pruning cut of the pruned branches is smooth and forms an angle of 45 degrees with the pruning cut buds. The cut of the branch is cut at the branch position and is level with the trunk without remaining residual piles. The bush branches should be level with the ground. The direction of the scissoring bud is selected according to the distribution condition of branches in the crown and the strength of the expected growth of new branches. When the crown needs to be expanded outwards, the scissoring buds are remained at the outer side of the branches; if the empty cavity is to be filled, the direction of the scissoring bud is inward; for branches which grow excessively, weak buds are used as scissoring buds for inhibiting the growth of the branches; when weak branches are supported, plump strong buds are selected as scissoring buds.

Aiming at the related technologies, the inventor thinks that when in tiller removal, not only branches but also residual piles need to be cut off, and the commonly used pruning scissors are inconvenient to operate and have the defect of influencing tiller removal efficiency of workers.

Referring to fig. 3, the connecting rod 2 is provided with a positioning component 4, and the positioning component 4 plays a role in improving the impact resistance of the cutter 1 when the cutter 1 splits and cuts residual piles. Locating component 4 includes locating piece 41 and positioning bolt 42, locating piece 41 is located between cutter 1 and the handle of a knife 3, locating piece 41 is close to 2 one ends of connecting rod and goes deep into inside connecting rod 2 through rectangular hole 21, positioning bolt 42 is located connecting rod 2 and deviates from locating piece 41 one side, positioning bolt 42 passes through

rectangular hole

21 and 41 threaded connection of locating piece, thereby fix locating piece 41 on connecting rod 2, when cutter 1 needs to split the stump, remove locating piece 41 to 1 department of cutter and back of a knife butt, then it is fixed, reach the effect of reinforcing cutter 1 shock resistance.

Referring to fig. 3, the first spring 22 is also positioned between the positioning block 41 and the adjustment lever 52 inside the connecting rod 2, and one end of the first spring 22 abuts against the adjustment lever 52 and the other end abuts against the positioning block 41. Because the existence of first spring 22 makes cutter 1 once remove the tiller after finishing, can automatic re-setting, even under first spring 22 compressed extremely limit state, locating piece 41 can't with the back of a knife blade butt, and that locating piece 41 also can realize dual fail-safe effect, avoids the unexpected slip after cutter 1 becomes flexible, guarantees the safety of staff.

Referring to fig. 3 and 4, the base plate 6 is provided with two limiting assemblies 7, the limiting assemblies 7 and the cutter 1 are located on the same side wall of the base plate 6, the two limiting assemblies 7 are symmetrically arranged on two sides of the cutter 1, the limiting assemblies 7 protect the cutter 1 when the cutter 1 is not used, meanwhile, the hand of a person is protected, and the hand of the person is prevented from being accidentally injured.

Referring to fig. 3 and 4, the limiting assembly 7 includes a baffle plate 71, a positioning tube 73 and a second spring 72, the positioning tube 73 is rectangular tube-shaped, one end of the positioning tube 73 is fixedly connected with the backing plate 6, one end of the baffle plate 71 is inserted into the positioning tube 73, and the outer wall of the baffle plate 71 in the positioning tube 73 is abutted to the inner wall of the positioning tube 73; second spring 72 is located registration arm 73, second spring 72 one end and baffle 71 fixed connection, and the other end and backing plate 6 fixed connection, second spring 72 are under the state of only receiving baffle 71 gravity compression, and baffle 71 is kept away from backing plate 6 one end and is compared the cutting edge of cutter 1 and be closer to handle of a knife 3 to including cutter 1 protection. The backing plate 6 is provided with two butterfly screws 8, one butterfly screw 8 corresponds to one baffle 71, the butterfly screws 8 and the baffle 71 are located on two sides of the backing plate 6, the butterfly screws 8 are in threaded connection with the backing plate 6, the butterfly screws 8 penetrate through the backing plate 6 and then are in rotary connection with the baffle 71, the baffle 71 rotates relative to the positioning pipe 73 by taking the central line of the butterfly screws 8 as a rotating shaft, in the embodiment, the baffle 71 is in a slip buckle state when being connected with the butterfly screws 8, so that the rotation of the baffle 71 is realized, and a bearing can be arranged between the butterfly screws 8 and the baffle 71, so that the rotation of the baffle 71 is realized. The second spring 72 is simultaneously sleeved outside the butterfly screw 8 in a loop mode, and a distance exists between the second spring 72 and the outer wall of the butterfly screw 8, so that the compression path of the second spring 72 is ensured, and the compression resistance of the second spring 72 caused by the threads of the outer wall of the butterfly screw 8 is reduced.

Referring to fig. 3 and 4, backing plate 6 deviates from cutter 1 one side and becomes wavy along being close to connecting rod 2 direction, and the finger of people's hand is laminated more to the wavy, and butterfly screw 8 is located wavy wave peak department, reduces butterfly screw 8 and to the hindrance of people's finger pulling backing plate 6. The position of the baffle plate 71 relative to the cutter 1 can be directly regulated and controlled by rotating the butterfly screw 8, so that the cutter 1 leaks out or is shielded by the baffle plate 71. An elastic pad 9 is fixed at one end of the baffle 71 far away from the backing plate 6, and the elastic pad 9 is made of rubber materials.

Referring to fig. 3, when the cutter 1 removes the tiller of the branch, a distance is left between one end of the cutter 1 close to the connecting rod 2 and the connecting rod 2, and the distance is the same as the distance from one end of the positioning block 41 far from the connecting rod 2 to the connecting rod 2, namely the positioning block 41 does not influence the insertion and embedding of the cutting edge of the cutter 1 in the elongated slot 31. Cutter 1 keeps away from 2 one ends of connecting rod and compares handle of a knife 3 and keeps away from 2 one ends of connecting rod and be close to connecting rod 2 more to avoid the staff to be by 1 marginal fish tail of cutter.

The implementation principle of the trunk tiller remover in the embodiment of the application is as follows: the butterfly bolt 51 is adjusted to enable the cutter 1 to slide on the connecting rod 2, the butterfly bolt 8 is adjusted to enable the baffle plate 71 not to shield the cutting edge any more, the palm abuts against the cutter handle 3, the pad 6 is pulled by fingers, so that the cutter 1 slides to a position close to the cutter handle 3, branches are cut off finally, and then the first spring 22 completes the reset of the cutter 1; when the stub is rejected to needs, rotate 180 with cutter 1, adjust butterfly bolt 51 and fix cutter 1 on connecting rod 2 completely, the position of simultaneously adjusting locating piece 41 provides dual fail-safe, holds handle of a knife 3, carries out the chopping of stub, and this application can adapt to the operation of removing the tiller of different states, reaches the effect that promotes staff and remove the tiller efficiency.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
