Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, a kind of gardens pruning machine, including rack 1 are fixedly installed with motor 2 in the rack 1 and slow down
The output shaft of device 3, the motor 2 is connected with the input shaft of retarder 3, and the side of the rack 1 is equipped with cutter mechanism, described to cut
Cutter mechanism includes: bottom knife 4 and cutter 5, and the bottom knife 4 is fixedly mounted in rack 1, and the cutter 5 is close to be cut
The blade surface of piece 4 offsets with bottom knife 4 close to two faces of blade surface of cutter 5, and crankshaft-link rod device 6 is equipped with inside the rack 1,
The rear end of the cutter 5 is connect with crankshaft-link rod device 6, and the crankshaft-link rod device 6 includes: crankshaft 7, connecting rod 8 and sliding block
9, one end of the crankshaft 7 is equipped with connecting rod 8, and the crankshaft 7 and connecting rod 8 are hinged, and described 8 one end of connecting rod is equipped with sliding block 9,
The connecting rod 8 and sliding block 9 are hinged, and output shaft and 7 gear of crankshaft of the retarder 3 link together, the upper slitter
5 surface of piece is equipped with sliding slot 10.
The rack 1 is mounted by means of screws with locating piece 11 close to the position of cutter 5, and the cutter 5 is under
The distance between 4 sawtooth of blade is 25-28mm, and 1 one side surface of rack is equipped with cable jack 12, the cable jack 12
Battery 13 is circumscribed with by power supply line.
It should be noted that the cutter mechanism of the pruning machine is made of cutter 5 and bottom knife 4, every piece of blade is just as saw
Sub the same, there is sawtooth on both sides, and bottom knife 4 is fixed in rack 1 at work, one end of cutter 5 and crankshaft-link rod device 6
In connecting rod 8 one end be connected, one end of crankshaft-link rod device 6 is connected with the output shaft of retarder 3, the input shaft of retarder 3
It is connected with the output shaft of motor 2, when motor 2 works, crankshaft 7 drives connecting rod 8 to rotate, and cutter 5 is under the limitation of locating piece 11
Longitudinally reciprocating motion is done along bottom knife 4, just forms the shear blade as scissors between each sawtooth at this time, every side has
15-18 sawtooth, the distance between every two sawtooth are 25-28mm, and the diameter that can be sheared is bigger.
Locating piece 11 is fixed in rack 1, plays a restriction effect to cutter 5, motor 2 work when, sliding block 9 with
The rotation of crankshaft 8 move reciprocatingly on sliding slot 10, thus make cutter 5 on bottom knife 4 between movement shearing branch, electricity
