Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch tree cutting machine for cutting pruned pruned trees, and more particularly to a rotary blade of a rotating rotary rotor so that a blade end of the rotary rotor protrudes from its peripheral edge. The present invention relates to a cutting machine for branches and leaves having attached.

2. Description of the Related Art Conventionally, as a cutting machine for branches and leaves having a flat blade protruding from a rotating cutting disk, Japanese Patent Publication No. 61-44641.
As a cutting machine as shown in Japanese Utility Model Publication No. 4-907, and as a cutting machine for branch and leaf trees in which a rotary blade is attached to a rotary rotor so that a blade end portion protrudes from a peripheral portion thereof, Cutting machines are known.

In the cutting machine for branches and leaves described in Japanese Utility Model Publication No. 4-907, a rotary blade for cutting the branches and leaves with a fixed blade has a substantially U-shaped taper-shaped mounting recess formed on a rotary rotor. It was attached by a mounting member. The rotary blade is mounted by fitting the rotary blade and the mounting member into the mounting recess and screwing a fixing bolt screwed onto the mounting member in the axial direction of the rotary rotor.

Further, in the cutting machine for branch and leaves of the publication, the feeding means for feeding the branches and leaves to the rotary rotor is a lower feed roller that can be positively rotated, and is swingable around a pivot shaft. It consists of a positively rotatable upper roller that is attached to the mounting case, and the pivot shaft of the mounting case is on the rear side of the upper roller (opposite the rotating rotor) and above the feeding roller axis. It was installed.

[0005]

However, in the cutting machine for branches and leaves described in the publication, in order to perform the cutting work, the mounting member and the rotary blade are substantially tapered in the mounting recess by screwing the fixing bolt. When removing the rotary blade attached in this way, it is not possible to remove the mounting member and the rotary blade that are in pressure contact with the side surface of the mounting recess by removing the fixing bolt. It is necessary to move the member by hitting it toward the shaft center, and the work is complicated because the mounting member is located closer to the shaft center than the rotary blade.

Further, since the rotary blade is mounted in the mounting recess by screwing the fixing bolt into the mounting member fitted together as described above, the degree of protrusion of the blade end portion of the rotary blade can be adjusted. Since it is necessary to consider that the rotary blade slides as the fixing bolt is screwed in, it is difficult to adjust the degree of protrusion of the blade end portion of the rotary blade. Especially,
When it is necessary to adjust the degree of protrusion due to abrasion of the blade end, the rotary blade itself has a narrow width in the blade end direction, and thus the above adjustment is very difficult.

Further, since the mounting recess is formed by engraving the recess in a substantially U-shaped taper shape on the cylindrical rotor, there is a problem in that the formation is complicated. It was

Further, since the feeding means is composed of the lower feeding roller and the upper roller, and the pivotal shaft of the mounting case of the upper roller is located on the rear side and the upper side of the upper roller, The cutting machine had to inevitably increase in size and weight.

Further, since the pivot shaft of the mounting case is located rearward and upward of the upper roller as described above, the vertical movement of the upper roller can be approximated to the direction perpendicular to the supply of the branches and leaves. In order to avoid contact with the rotating rotor, it was necessary to narrow the allowable range of vertical movement of the upper roller or position the pivot shaft further rearward. However, if the pivot shaft is located further rearward, there arises a problem that the cutting machine becomes larger and heavier as described above.

Further, in the branch and leaf cutting machine described in the publication, the drive source for supplying the branch and leaf and the drive source for the rotary rotor are separately controlled, so that the cutting with the rotary blade and the fixed blade is performed. It was difficult to obtain a cut product of a desired size, and in order to adjust the size of the cut product, it was necessary to use a screen fixed to the discharge port of the cutting machine.

Therefore, the present invention has been made to solve such a problem, and a first object of the present invention is to attach and detach the rotary blade very easily, and further It is an object of the present invention to provide a cutting machine for a branch tree, which is extremely easy to adjust the protruding length of the blade end portion when worn.

Further, an object of the present invention is to provide a cutting machine for a branch tree, which can very easily attach / detach the rotary blade and can surely prevent the rotary blade from coming off during the cutting work. Especially.

Another object of the present invention is to provide a cutting machine for branches and leaves, which can easily form a mounting portion of a rotary blade and can easily manufacture a rotary rotor.

Further, a cutting machine for branches and leaves which can reduce the size and weight of the cutting machine as a whole and a cutting machine for branches and leaves which can obtain a cut product of a desired size by cutting with a rotary blade and a fixed blade. It is also an issue to provide a cutting machine.

The cutting machine for branches and leaves according to the present embodiment has the above-mentioned structure. Hereinafter, a method of using the cutting machine for branches and leaves will be described. In the following description of the method of use, when the discharge amounts of the cutting hydraulic pump 22 and the feeding hydraulic pump 45 are set so that the outer edge portion of the feeding blade 50 rotates 20 mm per one rotation of the rotary rotor 19. Will be described.

First, in the case of finely cutting a branch tree when cutting the branch tree, when the screen 39 is attached by the bolt 41 and the size of the cut object cut by the rotary blade 33 and the fixed blade 59 is used. To leave the screen 39. The case where the screen 39 is attached will be described below.

When the pruned branches and leaves are placed on the chute table 67 and pushed into the feeding means 43 side, the branches and leaves on the chute table 67 move onto the fixed plate 57 and are rotated by the feeding means 43. It is sent to the rotor 19.

In this way, the rotating rotor is fed by the feeding means 43.
The branches and leaves sent to 19 are cut by the rotary blade 33,
It passes through the passage hole 39a of the screen 39 and falls from the discharge port 38 into the container 72.

Since the cutting machine for branches and leaves of this embodiment is used as described above, it has the following advantages.

Since the chute table 67 is provided, the branches and leaves can be placed on the chute table 67, and even if the branches and leaves have a certain length, the feeding means 43 can accurately rotate the rotary rotor.
Can be sent to 19.

Further, since the fixed plate 57 and the chute base 67 are provided so as to be inclined downward toward the rotary rotor 19,
The branches and leaves mounted on the fixed plate 57 and the chute base 67 easily slide to the side of the rotary rotor 19, and the branches and leaves on the fixed plate 57 can be easily fed to the rotary rotor 19 by the feeding roller 49, and the cutting is performed. You can work smoothly,
It is not necessary to employ a conveyor such as a belt conveyor as the lower fixed plate 57, and there is an advantage that the feeding means 43 can be made smaller and lighter.

Further, since the feeding roller 49 which can be moved up and down is adopted as the feeding means 43, the feeding roller 49 is moved up and down by the branches and leaves placed on the fixed plate 57 to be placed on the branches and leaves. It is possible to carry out feeding according to the amount and size of the tree, and moreover, since the branching tree can be fed while being pressed by the own weight of the feeding roller 49, the branching tree is carelessly rotated when cutting the branching tree 33. It is possible to perform cutting work accurately without escaping further.

Moreover, the notch 50a is formed on the outer edge of the feeding blade 50.
Since the notch 50 was formed,
It can be held by a and can be fed by the feeding blades 50 so that the branch portion substantially coincides with the feeding direction, and the branch and leaf can be fed to the rotary rotor 19 while being accurately held by the notch 50a. It has the advantage that it can be supplied.

Further, since the pivot shaft 55 of the swing member 53 to which the feed roller 49 is attached is located in front of the rotary roller 19, the swing of the swing member 53 causes the feed roller 49 to move up and down. The feeding of the branches and leaves can be approximated in the vertical direction, and the feeding means 43 can be compactly attached to the cutting machine body 17. Moreover, since the pivot shaft 55 of the swinging member 53 is provided in the front and below the rotation shaft 51 of the feeding roller 49,
Even if a force acts on the feeding roller 49 in the forward direction by the branches and leaves on the fixing plate 57, the swinging member 53 is also swung by the applied force to raise the feeding roller 49.

Further, a feeding hydraulic pump 45 for rotating the feeding roller 49 and a cutting hydraulic pump 22 for rotating the rotary rotor 19 are separately provided, and a hydraulic circuit for the feeding means 43 is provided. Since the hydraulic circuit for the cutting machine main body 17 and the hydraulic circuit for the cutting machine main body 17 are separately provided, the feeding means 43 can be driven arbitrarily even when the rotary rotor 19 is stopped.
Even if a branch tree is caught between the 33 and the fixed blade 59, the feeding roller 49 can be rotated in the reverse direction.

Further, the discharge amount of the feeding hydraulic pump 45 and the cutting hydraulic pump 22 is set so that the outer edge portion of the feeding blade 50 rotates 20 mm per one rotation of the rotary rotor 19, that is, the feeding roller 49 is rotated. Since the desired amount of branches and leaves are fed to the rotating rotor 19 side per one rotation of the blade 33, the amount of branches and leaves sent per one cut of the rotating blade 33 can be adjusted and rotated. By cutting the blade 33, the cut object can be made to have a constant size, and thus the cut object of a desired size can be obtained by the rotary blade 33 and the fixed blade 59. Moreover, by changing the discharge amount of the feeding hydraulic pump 45 or the cutting hydraulic pump 22, it is possible to change and set the amount of the branch and leaf trees sent per one cutting of the rotary blade 33, thereby rotating The size of the cutting object obtained by cutting with the blade 33 and the fixed blade 59 can be changed.

Further, since the rotary rotor 19 is provided with a relief portion 28 capable of withdrawing the cut branches and leaves from the protruding position of the blade end portion 34 of the rotary blade 33 in the rotational peripheral edge, A part of the foliage that has been cut is a relief part of the rotating rotor 19.
In order to escape to the 28, the rotary rotor 19 is cut by a part of the cut material while cutting the branches and leaves with the rotary blade 33.
The cutting work can be performed smoothly without hindering the rotation of the.

Further, the substantially L-shaped mounting notch 29 is provided with a rotary blade.
The rising surface against the mounting surface 30a that abuts the side surface of 33
Since the peripheral side of 30b is formed so as to be inclined toward the blade end 34, centrifugal force acts on the rotary blade 33 and the holding member 31 attached to the mounting notch 29 when the rotary rotor 19 is rotated at high speed. However, a reaction force from the rising surface 30b acts on the holding member 31 against this centrifugal force, and the holding member 31
