Description
Technical Field
The utility model relates to a pruner.
Background
Pruners are used to prune branches using shear forces between blades. Generally comprises a fixed blade fixed on a frame and a movable blade connected with the frame in a sliding way. The branches are cut off by driving the movable blade to reciprocate. The common driving mechanism comprises a motor, and the motor drives the movable blade group to reciprocate through a turntable sliding block mechanism, so that the pruning of the branch pairs is realized. However, with this structure, when the movable blade and the fixed blade are stuck by a hard object, the motor stops rotating suddenly, which causes the motor to be subjected to a large shock instantaneously, which affects the product life, and therefore, there is a need for improvement.
Disclosure of Invention
To the not enough that exists among the prior art, the utility model provides a pruner can effectively reduce the impact that the motor received after the card is dead.
The utility model discloses a realize through following technical scheme: the pruner comprises a frame and a driving mechanism, wherein the frame is provided with a row of fixed blades and a row of movable blades, the fixed blades are fixed on the frame, the movable blades are connected into a whole through a connecting sheet, the connecting sheet is connected on the frame in a sliding way, the driving mechanism comprises a motor, a turntable and a connecting rod, the motor drives the turntable to rotate, one end of the connecting rod is connected on the turntable in a rotating way, the other end of the connecting rod is connected on the connecting sheet in a rotating way, the pruner also comprises a coupler, the coupler comprises two sleeves and a damping sheet, one end of the two sleeves, which is contacted with each other, is provided with a plurality of bulges and grooves, the bulges on one sleeve are inserted into the grooves on the other sleeve, the other ends of the two sleeves are respectively connected with the motor output shaft and the rotating shaft of the turntable, and the damping sheet comprises a plurality of fins, the fins are arranged in the grooves and clamped into the two side faces of the protrusions. When the shearing device is used, the motor drives the rotary table to rotate, the rotary table drives the connecting sheet to reciprocate through the connecting rod, the whole row of movable blades are further driven to reciprocate, and the movable blades and the fixed blades are sheared mutually. If meet hard thing, can't cut off, the mutual extrusion of sleeve, with the fin extrusion deformation of shock attenuation piece, the shock attenuation piece has absorbed the device and has met the impact of heavy object card dead suddenly, avoids the motor to strike too big in the twinkling of an eye, influences product life.
In the above technical scheme, preferably, the fixed blade includes a body and a strip-shaped groove located at the bottom of the body, and the movable blade passes through the strip-shaped groove. According to the structure, when the pruning machine is used for pruning, two ends of a pruned branch lean against two end faces of the strip-shaped groove, then the movable blade is sheared, the shearing is more reliable, and the occurrence of lateral force is avoided.
In the above technical solution, preferably, both ends of the moving blade are provided with blades. Both sides all set up the cutting edge, can let the movable blade can both accomplish once shearing in reciprocating stroke, improve shearing efficiency greatly.
Compared with the prior art, the beneficial effects of the utility model are that: when the shearing device is used, the motor drives the rotary table to rotate, the rotary table drives the connecting sheet to reciprocate through the connecting rod, the whole row of movable blades are further driven to reciprocate, and the movable blades and the fixed blades are sheared mutually. If meet hard thing, can't cut off, the mutual extrusion of sleeve, with the fin extrusion deformation of shock attenuation piece, the shock attenuation piece has absorbed the device and has met the impact of heavy object card dead suddenly, avoids the motor to strike too big in the twinkling of an eye, influences product life.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
referring to fig. 1 and 6, the pruner comprises a frame 1 and a driving mechanism 2, wherein the frame 1 is provided with a row of fixed blades 6 and a row of movable blades 3, the fixed blades 6 are fixed on the frame 1, the movable blades 3 are connected into a whole through a connecting sheet 4, the fixed blades 6 comprise a body 61 and a strip-shaped groove 62 positioned at the bottom of the body 61, and the movable blades 3 penetrate through the strip-shaped groove 62. According to the structure, when the pruning machine is used for pruning, two ends of a pruned branch lean against two end faces of the strip-shaped groove, then the movable blade is sheared, the shearing is more reliable, and the occurrence of lateral force is avoided. Both ends of the movable blade 3 are provided with blades 31. Both sides all set up the cutting edge, can let the movable blade can both accomplish once shearing in reciprocating stroke, improve shearing efficiency greatly. The connecting piece 4 is connected to the frame 1 in a sliding manner.
The driving mechanism 2 comprises a motor 21, a rotary table 22, a connecting rod 23 and a coupler 5, the motor 21 drives the rotary table 22 to rotate through the coupler 5, one end of the connecting rod 23 is rotatably connected to the rotary table 22, and the other end of the connecting rod 23 is rotatably connected to the connecting piece 4.
The shaft coupling 5 includes two sleeves 51 and shock attenuation piece 52, is provided with the arch 511 and the recess 512 of several on the one end that two sleeves 51 contact, one of them protruding 511 on the sleeve 51 inserts another in the recess 512 on the sleeve 51, two the other end of sleeve 51 is connected respectively the motor 21 output shaft with the pivot of carousel 22, shock attenuation piece 52 includes several fin 521, fin 521 sets up in the recess, fin 521 card goes into the both sides face of protruding 511.
When the shearing device is used, the motor drives the rotary table to rotate, the rotary table drives the connecting sheet to reciprocate through the connecting rod, the whole row of movable blades are further driven to reciprocate, and the movable blades and the fixed blades are sheared mutually. If meet hard thing, can't cut off, the mutual extrusion of sleeve, with the fin extrusion deformation of shock attenuation piece, the shock attenuation piece has absorbed the device and has met the impact of heavy object card dead suddenly, avoids the motor to strike too big in the twinkling of an eye, influences product life.
