Problems solved by technology

The trimming of garden trees is usually done by the garden staff standing on the ground and using an extension pole, fixing a hand saw on the head of the pole to cut off the branches, or by the garden staff going up the tree through a ladder, and sawing off the branches at a higher position, which is safe for climbing the tree The shortcomings of poor performance, the need to hold your head up and raise your arms on the ground are labor-intensive and low-efficiency manual operation

Abstract

The invention discloses a portable automatic saw blade saw. The portable automatic saw blade saw comprises a saw blade and lengthening rods, and is characterized by also comprising a base frame, wherein the base frame is fixedly connected with a supporting base and a guide block respectively; a direct-current motor is fixedly connected to the supporting base; a power shaft of the direct-current motor is connected with the saw blade through a power transmission device; the power transmission device is a crank slide block mechanism; one end of a crank is fixedly connected with the power shaft of the direct-current motor; the other end of the crank is hinged with one end of a connecting rod; the other end of the connecting rod is hinged with one end of a slide block; the other end of the slide block is fixedly connected with a smooth shaft; and the smooth shaft is arranged in the guide block which is glidingly matched with the smooth shaft. When the portable automatic saw blade saw is used, the number of the lengthening rods is determined according to the trimming requirements on tree branches with different heights, a connecting pipe is fixedly connected with the lengthening rods, a control cable is plugged into a power supply, the saw blade is arranged close to the tree branch to be trimmed, a switch is turned on, the power shaft drives a power transmission device to drive the smooth shaft and the saw blade to reciprocate along the guide block to cut the tree branch, and after trimming is finished, the switch is turned off, the saw blade stops moving. The portable automatic saw blade saw has the advantages of high safety, low labor intensity and high efficiency.
