When the soil ball digging machine is used, only half of soil balls of tree roots can be dug at a time, so that two operations are needed for digging the whole tree, the operation is complicated, and the operation efficiency is low.
Disclosure of Invention
The reciprocating saw tree mover has the advantages of simple structure, small volume, convenient operation and convenient use, and can finish various tree digging operations by only one person, thereby having high efficiency.
In order to achieve the purpose, the technical scheme of the patent is as follows:
a reciprocating saw tree mover comprises an annular bracket 1 with an opening, a sliding block 2 arranged on the bracket 1 in a sliding way, and a saw frame 3 provided with a guide groove 31 and a sliding groove 32 which are communicated with each other; the saw blade 4 comprises an upper handle 41 and a lower working part 42 with saw teeth 43, wherein the handle 41 is arranged in the guide groove in a reciprocating sliding way, the working part 42 extends into the sliding groove 32, and the saw teeth 43 are arranged outside the sliding groove and are positioned on one side of the saw frame; a saw blade driving device 5 for driving the saw blade to slide reciprocally in the guide groove and the sliding groove is arranged on the saw frame; the saw frame 3 is arranged on the slide in a manner of swinging at least 180 DEG, and can swing 90 DEG from a 0 DEG position which is in the same plane with the bracket to a sawing position: the saw frame and the saw blade extend downwards from the periphery of the bracket and towards the central axis of the bracket, and the lower end of the saw blade extends to the central axis of the bracket; a detachable locking device 6 for locking the saw frame in the sawing position is arranged between the saw frame and the slide.
The beneficial effects of the technology are that: this patent is when using, and the trunk moves into in the support through the opening on the annular support 1, and the support uses the trunk to encircle the trunk as the center, trunk axis and the coincidence of support central axis. In the initial state, the saw frame and the bracket are positioned at 0 DEG of a plane, and the saw teeth face the ground (see figure 3). The saw blade driving device is then started, and the saw blade starts to reciprocate. Then, the saw frame is swung so that the saw frame swings downwards from the 0 DEG position, the saw blade for cutting off the root of the tree gradually cuts into the ground until the saw frame swings 90 DEG to reach the sawing position, namely, the saw frame and the saw blade extend downwards from the periphery of the bracket and towards the central axis of the bracket, and the lower end of the saw blade extends to the central axis of the bracket. At this point the saw frame is locked in this sawing position by means of the locking means 6. The redrive slide (including the saw frame on the slide, etc.) slides along the bracket from one end of the opening to the other end of the opening in the bracket. The locking device is then removed, the saw frame is driven to swing upwards by 90 ° from the sawing position, the saw blade reaches from below the ground onto the ground, the saw frame and the support are in a 180 ° position in the same plane (see fig. 4), and the saw teeth face away from the ground (see fig. 4). Thus, the digging of the root soil balls is completed, and the digging of the whole tree is completed.
The reciprocating saw tree mover comprises a saw blade driving device 5, wherein the saw blade driving device comprises a rotating cam 51, and the cam is contacted with the inner wall of a hole formed in a handle part; the saw blade is driven to slide reciprocally through the rotation of the cam. The cam mechanism brings the saw blade to slide reciprocally, so that the structure is simpler.
In the reciprocating saw tree mover, the saw frame 3 is arranged on the sliding block in a swinging way through a pivot 7; the locking device 6 is a pin shaft which can be inserted into lock holes formed on the sliding block and the saw frame at the same time, and the pin shaft is parallel to the pivot.
The reciprocating saw tree mover comprises a bracket, wherein the bracket comprises an upper arc rod and a lower arc rod, 3 rollers 21 are arranged on a sliding block, one roller at the upper part is matched with the upper arc rod 11, and two rollers at the lower part are matched with the lower arc rod 12. Preferably, the upper arc-shaped rod and the lower arc-shaped rod are connected through a c-shaped piece 13 positioned at the inner periphery of the bracket, and the saw frame is positioned at the outer periphery of the bracket; a pin 14 is fixed to the bottom end of the c-shaped member 13. The sliding block is arranged on the bracket in a rolling way through the roller, so that the resistance is smaller. Meanwhile, the c-shaped piece 13 on the inner periphery of the bracket and the sliding of the sliding block can not interfere, and the structure is ingenious. The contact pin can be inserted into the ground to play a role in stabilizing the whole reciprocating saw tree mover.
The reciprocating saw tree mover further comprises a handle 8 arranged on the saw frame for operating the saw frame to swing.
The reciprocating saw tree mover has arc saw frame with runner and saw blade with work part. The root soil ball of the dug tree is basically hemispherical.
