Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a root vegetable cutting device for harvesting roots and leaves of beets, radish, and other root vegetables growing in fields.

(Prior Art) When harvesting root vegetables, such as beets, from a field, the order of operations is that the stems and leaves are harvested while they are still planted in the field, and then the beets are dug up.

As a working machine to be used for cutting the leaves in this case, the one described in JP-A-59-187712 has been proposed.

This machine is equipped with a filler wheel that moves over the beet stems and leaves, and a knife that moves up and down in conjunction with the vertical movement of the filler wheel and cuts the stems and leaves on the upper side of the beet. be.

(Problem that the invention aims to solve) However, with this method, the stems and leaves are simply harvested from the upper part of the beet, so when the beet is dug up with a digging machine after reaping, the long stems and leaves remain in the digging area. There was a risk that the arms and the like could become entangled, resulting in a significant increase in digging resistance.

In addition, the harvested stems and leaves may be picked up by a so-called top harvester and collected in a wagon before digging, and used as feed. In this case, if the foliage is large and bulky, the amount that can be loaded onto the wagon will be small, resulting in inefficiency.

The present invention was provided for the purpose of solving such conventional problems.

(Means for Solving the Problems) The technical means taken by the present invention to achieve the above-mentioned object are characterized by the fact that the mobile body 1 having the ground-contact driving wheels 3 is The knife 21 is equipped with a moving filler wheel 11 and a knife 21 that moves up and down together with the filler wheel 11 to harvest the stems and leaves on the upper side of root vegetables. , a plurality of rearwardly protruding tines 32 are provided in the lateral direction, and a shredding device 33 for shredding the leaves B on the tines 32 is provided.

(Function) When cutting the stems and leaves of root vegetables, the filler wheel 11 moves over the stems and leaves of the root vegetables, so the knife 21 moves in conjunction with its vertical movement.
It moves up and down, cutting the root vegetables from the top side and harvesting the stems. The leaves B cut by the knife 21 are received by tines 32 and cut into small pieces by a shredding device 33 rotating around a horizontal axis.

A gauge wheel 40 is attached to the lower end of the vertical rod 42 via a stay 41, and the vertical rod 42 is supported by a holding cylinder 43 provided on one side of the machine frame 5 and can be adjusted up and down by a handle 44. It is free.

Next, the operation of the above configuration will be explained. When cutting the stems and leaves of beet A and B, the mobile body 1 is operated so that the drive wheels 3 pass on both sides of the ridge C in which beet A is planted. Then, the filler wheel 11 passes over the foliage B of the beet A, and while raising and lowering the knife 21 in accordance with the size of each beet A, the knife 21 cuts the foliage B from the upper side of the beet A. , the stems and leaves B are shredded with a rotary blade 35. That is, since the filler wheel 11 is vertically movable by the swing arm 16 and is rotationally driven by the power from the axle 2,
Even if there is a difference in height on Beat A, you can move over it one by one. On the other hand, the knife 21 is supported via a parallel link mechanism 28, and the movable plate 25 is connected to the swing arm 16 via a connecting link 29, so that when the filler wheel 11 moves up and down, The knife 21 moves up and down. Therefore, the knife 21 moves while drawing a trajectory D as shown in FIG. 1, and cuts the stems and leaves B at a certain height from the upper end at each beat A.

This is the arm length 1 of the filler wheel 16.
The arm length 28A of the knife 21 is shorter than 6A, and this is achieved by creating a difference in the amount of rise of the filler wheel 16 and the knife 21.

The filler wheel 11 also includes a transmission mechanism 18,
At this time, the transmission mechanisms 18 and 19 rotate the filler wheel 11 earlier than the drive wheel 3 (in the embodiment, the filler wheel 11 rotates together with the drive wheel 3).
2) The knife 21 rotates, and therefore, when tapping the beat A with the knife 21, it is tilted forward relative to the driving force of the drive wheel 3, forcing the beat A to occur and ideal tapping is performed. becomes.

Furthermore, the leaves and leaves that tend to get stuck on the rear side of the knife 21 are removed outwardly by the leaves and leaves removal tool 22A provided on the front side of the knife 21.

Furthermore, in the first embodiment, the leaves B cut by the knife 21 flow backward and are received on the tines 32 as shown in FIG. It is shredded into pieces the size of a pitcher. Therefore, after that, stems and leaves B
Even if beets A are left in the field and the beets A are dug up using a digging machine, the stems and leaves B remain large and do not get tangled with the arm of the excavator, and the stems and leaves B after reaping. Even when collected and loaded onto a wagon for use as feed, since it is shredded, it does not take up much bulk and can be loaded onto the wagon with good density. Note that the rotary blade 35 rotates at a higher speed than the filler wheel 11.

During such work, the swing arm 16 is in the upper position as shown in FIG.
1, and the swing arm 16 and the parallel link mechanism 28 are connected to the filler wheel 11.
can move up and down so that it can climb over the stems and leaves B of beet A.

Note that although the rotary blade 35 is shown as having chevron-shaped teeth on the outer periphery, it may be in the shape of a disk. Further, the shredding device 33 is not limited to a rotary type, but may be a reciprocating type. Furthermore, the tines 32 on the rear side of the knife 21 can be used when the knife 21 is wide, etc.
It can be omitted if there is no risk that the stems and leaves B will fall before being shredded.

(Effects of the invention) According to the invention, the knife 21 is provided with a plurality of tines 32 that project backward in the lateral direction so as to receive the cut leaves B, and is a shredding device that shreds the leaves B on the tines 32. 33, even if the beets A are dug up while leaves B are left in the field, they are less likely to get entangled with the arms of the digging part, and thereby the digging resistance is not increased.

Furthermore, when the harvested foliage B is collected and loaded into a wagon for use as feed, since it has been shredded, it is less bulky and can be loaded with good density.
