The topsoil can be moved near the roots of the crops planted in the area to make a landfill. Simultaneously with the excavation of the topsoil described above,
The weeds in the germination stage (2 to 5 cm) can be pulled out and weeded.

On the contrary, the right and left cage rollers 2
Is set to a substantially C-shape in plan view and when the vehicle is towed, the ridge d
Excessive land close to the root of the crop of the ridge d2 on both sides sandwiching 2 can be dislodged toward the central ridge d2. Also, in the case of removing the soil, the weeds in the germination stage can be pulled out and weeded simultaneously with excavation of the topsoil. As described above, in order to support the two cage rollers 2 in a C-shape in plan view, remove the bolt 15a and rotate the tip of the stopper plate 15 backward,
The bolt holes 15c of the stopper plate 15 are aligned with the bolt holes 16c of the arm plate 11a, and the bolts 15a are fixed.

Further, the left and right cage rollers 2 are in a neutral state,
That is, when the vehicle is towed in a state where both ends of the support shaft 13 are warped upward in a straight line in a plan view and in a front view, the top soil is excavated from the side surfaces of the ridge d2 on both sides sandwiching the ridge d2 and the ridge d. Thus, the weeds in the germination stage can be pulled out and weeded.

As shown in FIGS. 7 and 9, the above-mentioned basket rollers a and a 'for the field weeding machine extend right and left from the central shaft support portion 10 (in the case of the roller a', either one of the right and left).

However, by moving the collar 25 from the inside to the outside of the substrate 22 of the cage roller 2, the width from the center of the shaft support 10 at the lower end of the frame 1 to the tip of the cage roller 2 moves as described above. The distance between the cage-shaped roller 2 and the cage-shaped roller 2 opposed to each other with the ridge d1 therebetween is widened by the amount of the collar 25 that has been made.

By moving the fitting position of the collar 25 from the outside of the substrate 22 of the basket-shaped roller 2 to the inside thereof, contrary to the case described above, the center of the shaft support 10 at the lower end of the frame 1 is moved from the center. The width dimension up to the tip of the cage roller 2 increases by the length of the collar 25 moved as described above,
The distance between the basket-shaped roller 2 and the adjacent cage-shaped roller 2 opposed to each other across the ridge d1 is reduced.

That is, as described above, by moving the collar 25 fitted on the support shaft 13 with the substrate 22 of the cage roller 2 as a boundary, the two cage rollers 2 opposed to each other with the ridge d1 interposed therebetween.
Can be changed stepwise according to the width of the ridge d1 and the growing process of the crop, whereby the other end of the basket-shaped roller 2 can be moved without damaging the leaves and stems of the crop. Weeding can be performed effectively close to the stem of the crop (FIGS. 8 to 9). It should be noted that one or more of the above-mentioned collars may be mounted, and the length per one may be arbitrarily changed.

Therefore, the crop weeding roller constructed as described above is mounted on a weeding machine connected to the rear part of the tractor so that the substantially cylindrical cage roller having the other end opened is grounded to the ground. It will be in the state of having done. Then, by running the self-propelled device, the basket-shaped roller is pulled along the ridge and the ridge to roll and rotate, and the outer periphery of the cage-shaped roller is stalked with the crop planted in the ridge. Rolling and rotating while being in contact with the topsoil in the range of the ridge, the topsoil is excavated by a number of rods constituting the outer peripheral portion of the roller, and the germinating weeds that grow there are pulled out and reliably weeded. Further, since the frame of the crop weeding roller is provided so as to protrude upward from the middle of the two cage rollers, it is possible to bring the other end side of the basket roller sufficiently close to the stem of the crop. Also, unlike the conventional frame, the frame supporting the basket-shaped roller from the left and right sides does not damage the foliage of the crop. further,
The basket-shaped roller configured as described above rolls and rotates by pulling, thereby crushing the earth mass by each bar material to make the earth fine. In addition, the cage-shaped roller breaks down the soil mass that has entered the roller from the other end of the roller and the gap between the rods to form fine soil, and at the same time, moderately softens the soft and thinned ground. be able to.

The width between the shaft support at the lower end of the frame and the tip of the basket-shaped roller can be adjusted by changing the distance between. Therefore, by exchanging the above-mentioned collar between the inside and the outside of the substrate of the basket-shaped roller, it is possible to arbitrarily adjust the interval between the other ends of the adjacent basket rollers for the field weeding machine, and sandwich the ridge. It is possible to arbitrarily change the interval between the other ends of the two opposing cage rollers in accordance with the width of the ridge and the size of the crop. As a result, it is possible to bring the other end side of the basket-shaped roller sufficiently close to the stalk of the crop without damaging the leaf stalk of the crop, and it is possible to perform more effective weeding and burrowing.

The basket roller for a field weeding machine according to claim 4 is
By inserting a support shaft bent in a substantially U-shape into a shaft support portion at the lower portion of the frame, and by configuring this support shaft to be rotatable and fixable at a predetermined rotation position, the support shaft is free to rotate. The configuration is such that the support angle in a plan view of the left and right basket-shaped rollers rotatably supported can be changed to a C-shape, an inverted C-shape, and a neutral position. According to the above-described means, for example, the left and right basket-shaped rollers that are pivotally supported across the shaft support portion are fixed at a position having a substantially C-shape in plan view and are towed to travel. The topsoil can be excavated from the side, and the lands at the side of the ridge can be dislodged toward the center ridge, and at the same time, weeds can be removed at the germination stage. On the other hand, when the left and right cage rollers are fixed at a position having a substantially inverted C shape in a plan view, the top soil is excavated by the rolling rotation of the two cage rollers, At the same time, weeding is carried out toward the slope of the ridge, and weeds at the germination stage can be eliminated. Further, when the left and right basket-shaped rollers are set to be parallel and neutral, the rolling rotation of the two basket-shaped rollers excavates the central ridge and the topsoil on the slopes of the left and right ridges sandwiching the center ridge. Weeds can be weeded.
