Description

[Detailed Description of the Invention] The present invention relates to a root digging machine side blade attachment member that allows the blade for digging the soil around a tree to be transplanted to be opened to either the left or the right.

Generally, transplanting a tree requires rooting work, digging up the soil at the replanting site, cutting the tap root, etc.
Conventionally, these operations have been performed using shovels, saws, etc. exclusively by input.

However, the work efficiency of manual labor is extremely low, and the landscaping industry is suffering from a chronic labor shortage, and the desire to improve work efficiency is increasing day by day in this type of industry. Ta.

For this reason, a root digging machine was devised that improves work efficiency by allowing trees to be transplanted mechanically.

The present invention is a root digging machine in which the blade that digs the soil around the tree to be transplanted can be opened to either the left or right in order to make it easier to transplant a tree planted in a corner. To provide a side blade attachment member for a root digging machine.

The present invention will be explained in detail below with reference to the drawings.

In Figures 1 to 5, 1 is a root digging machine installed in place of the rough cutting attachment of backhoe B,
This has a bifurcated tip, and the rear end is rotatably attached to backhoe B. In order to move the boom 2 up and down, one end is pivoted to the lower middle of boom 2, and the other end is pivoted to the bottom of the middle of boom 2.
The boom 2 is composed of a cylinder 3 which is pivotally supported by a cylinder 3, a pair of left and right force movement mechanism parts 4, 4 provided at the tip of the boom 2, and a drive part 5 that drives the force movement mechanism parts 4, 4.

The force movement mechanism parts 4, 4 are provided with spline shafts 8, 8 and 9.9, each of which has an involute serration shape at both ends, which are rotatably supported by bearings 6, 6 and 7, 7, respectively. Gears 10, 10, 11, 11 that mesh with each other are meshed with one end of each of the spline shafts 8, 8 and 9, 9, and a blade for attaching a front blade is provided at the other end of one of the spline shafts 8, 8. The boss portion 13.13 of the mounting plate 12.12 meshes with the locking portion 14.1 of the blade mounting plate 12.12.
Attachment portions 16.16 at both ends of the approximately semicircular front blade 15 are fitted into 4, and these retaining portions 14.14 and attachment portions 16.16 are connected by a removable locking pin 17.17. and a substantially semicircular rear blade 1 at the other end of the other spline shaft 9, 9.
Both ends of 8 are engaged.

Further, the drive unit 5 connects a cylinder 19 whose one end is pivotally supported above the rear end of the boom 2 with the other end of an idler lever 20 whose one end is pivoted above the middle part of the boom 2, and a link lever 21. . There is.

In the figure, reference numeral 23 denotes a cover for the force movement mechanism parts 4, 4, and a front blade holding member 24 is provided on the upper surface of the cover to hold the front blade 15 open to either the left or right side.

The check-off machine 1 configured in this way moves the backhoe B close to the tree to be transplanted with the boom 2 raised by the cylinder 3, pulls out either the left or right locking pin 17, and removes the front blade. The front blade 15 is rotated and opened using either the left or right mounting part 16 of the blade 15 as a pivot point, and a tree is inserted between the force movement mechanism parts 4, 4, and the front blade 15 is closed again. The front blade 15 is attached to the blade mounting plate 12 by fitting the attachment part 16 into the locking part 14 and inserting the locking pin 17.

After that, the boom 2 is lowered and the force movement mechanism parts 4, 4 are lowered.
ground, and then actuate the cylinder 19 to connect the idler lever 20 and the link levers 21, 21, which are link mechanisms.
and link motion of the auxiliary link levers 21.21.

As a result, the spline shafts 8.8 are rotated to rotate the front blade 15 counterclockwise in FIG. The blade 18 is rotated clockwise in FIG. 1, the front blade 15 and the rear blade 18 are overlapped below the tree to be transplanted, and the roots are cut while the soil around the tree remains attached to the roots.

Therefore, in the tree cutting work, even if the tree to be transplanted is located in a corner of a landscaping site and the direction of rotation of the front blade 15 is restricted, the front blade 15 is not connected to the blade mounting plate 12. The mounting part 16, which is fixed to the locking part 14, serves as a pivot point and can be opened to either the left or right side, and the front blade 15 can be held open, so that the space between the force movement mechanism parts 4, 4 can be kept open. It became possible to easily insert trees into the area.

As described above, the blade mounting member for the teller bar of the present invention is such that the blade mounting plate is mounted on the shaft of the pair of left and right force movement mechanisms that are rotated by a link mechanism driven by a drive source such as a hydraulic cylinder or an electric motor. The mounting parts at both ends of the front blade are fitted into the locking parts of this blade mounting plate, and the removable locking pins are locked to the locking parts and the mounting parts. The attachment parts at both ends of the blade are locked to the locking parts of the blade mounting plate by locking pins, so by pulling out either the left or right locking pin, the mounting part will be connected to the locking part by the locking pins. The front blade can be rotated and opened using the tethered side as a hinge, so when transplanting a tree planted in a corner, the front blade can be opened on either the left or right side.
