Pruning machine

Abstract

The invention discloses a pruning machine, which comprises a blade component, a shell, a prime motor and a transmission device. The blade component comprises a first blade and a second blade; the first blade comprises a first body portion and a first cutting tooth portion; the second blade comprises a second body portion and a second cutting tooth portion. The first blade further comprises a firstconnection group, the first connection group comprises a first driving portion and a first connection portion, and the first connection portion is connected with the first body portion to enable thefirst body portion to move along with the first driving portion. The second blade further comprises a second connection group, the second connection group comprises a second driving portion and a second connection portion, and the second connection portion is connected with the second body portion to enable the second body portion to move along with the second driving portion. The first connectionportion and the first body portion are in detachable connection, the second connection portion and the second body portion are in detachable connection, and the first connection portion is at least partially positioned outside the shell. The pruning machine has the advantage that the first body portion and the second body portion can be quickly detached by a user.

Description

technical field [0001] The invention relates to a garden tool, in particular to a pruning machine. Background technique [0002] As a garden tool, the pruning machine is widely used for trimming shrubs, hedges and other vegetation. [0003] The pruning machine generally includes: a casing, a prime mover, a transmission and a blade assembly, wherein the prime mover and the transmission are arranged in the casing, a part of the blade assembly is located in the casing, and the other part protrudes forward to the casing outside. Wherein, the casing includes a main body and a maintenance cover. The maintenance cover is arranged on the lower side of the main body. When the maintenance cover is docked with the main body, a housing cavity for accommodating the prime mover and the transmission device is formed around the blade assembly. The cover and the main body are usually connected by multiple screws, and the number of screws for installing the maintenance cover is generally 6 ...

AI Technical Summary

Problems solved by technology

For the existing pruning machine, when the operator replaces the blade assembly, the maintenance cover needs to be disassembled first, and then the first blade and the second blade are disassembled from the support. During the whole disassembly process, the operator usually needs to disassemble 12 to There are 18 screws, and it usually takes about 20 seconds to remove one screw, so it takes 4 to 10 minutes just to remove the screw, and then you need to install a new first blade and second blade, the whole disassembly process takes about 20 minutes to half an hour, which will seriously reduce the operator's work efficiency

Moreover, removing the maintenance cover and exposing the transmission device may cause the position of each part in the transmission device to change, which will further prolong the time for replacing the blade assembly, and may even reduce the stability of the transmission device

Furthermore, replacing the entire first blade and the second blade will greatly increase the operating cost of the operator
