Problems solved by technology

[0003] Most of the existing pruning operations are performed with pruning scissors. Sanitation workers operate the pruning scissors to prune the branches with a huge amount of labor, and the pruning efficiency is low. There are also some mechanical pruning machines for pruning. However, the current pruning Most of the machines use gasoline motors to drive the cutters to implement pruning operations. The above-mentioned pruning machines are not only expensive, but also not environmentally friendly, and the weight is too large. It is extremely inconvenient for users to use in practice.

Embodiment Construction

[0013] combine Figure 1 to Figure 5 , the present invention is further described:

[0014] The pruning device comprises a handle bar 10, the handle bar 10 is provided with a chain saw disc 20, the edge of the chain saw disc 20 is rotatably provided with a chain saw 21, and blades are arranged at intervals along the circumferential direction of the chain saw 21 22. A dial 30 is arranged on the side of the chain saw disc 20, and the power mechanism drives the dial 30 to rotate. The dial 30 is provided with a driving groove 31 in the circumferential direction, and the chain saw disc 20 is movable. At the front end of the handle bar 10 , the driving mechanism drives the chainsaw disc 20 to reciprocate along the length direction of the handle bar 10 and makes the blade 22 approach or move away from the driving groove 31 .

[0015] combine Figure 1 to Figure 5 As shown, the operator holds the handle bar 10, and the power mechanism here can be a motor. By touching the switch on t...

Abstract

The invention relates to a pruning device which comprises a handle rod, wherein a chain saw disk is disposed on the handle rod; a chain saw is disposed on the edge of the chain saw disk in a rotatable manner; blades are disposed at intervals along the circumference of the chain saw; a dial wheel is disposed on the lateral side of the chain saw disk; a power mechanism drives the dial wheel to rotate; a drive groove is formed in the circumference of the dial wheel; the chain saw disk is movably disposed on the front end of the handle rod; a drive mechanism drives the chain saw disk to move back and forth along the length direction of the handle rod; and a blade extrudes into the drive groove. An operator holds the handle rod, wherein the power system here can be a motor; and the operator touches a switch on the handle rod so as to drive rotation of the dial wheel. The drive mechanism drives the chain saw disk to move back and forth along the length direction of the handle rod, and the dial wheel rotated at a high speed drives the chain saw to rotate on the chain saw disk, so that saw cutting operations can be conducted to branches. The pruner has a light weight, can be operated easily and can significantly increase pruning efficiency.

Description

technical field [0001] The invention relates to the technical field of sanitation equipment, in particular to a pruning device. Background technique [0002] With the development of cities in our country, more and more attention has been paid to urban greening. Many trees need to be pruned. Tree pruning is not only beneficial to the growth of trees, but also ensures the overall cleanliness of trees, especially in cities in our country. On roads, parks and campuses, the sanitation department needs a large number of sanitation workers for pruning operations every year. [0003] Most of the existing pruning operations are performed with pruning scissors. Sanitation workers operate the pruning scissors to prune the branches with a huge amount of labor, and the pruning efficiency is low. There are also some mechanical pruning machines for pruning. However, the current pruning Most machines use gasoline motors to drive cutters to implement pruning operations. The above-mentioned ...
