Description

[Detailed description of the invention] I. Purpose of the invention A. Industrial field of application This invention relates to a weeding device for a rotary reaper.

B. Conventional technology and its problems Conventionally, this type of technology is as follows.

2. Description of the Related Art Apparatuses for harvesting long-stem crops such as dent corn and spreading the crops to the right or left side using a conveyor belt having protrusions are known.

However, in the conventional machine, when the grass culling device section is switched from side to side, the support wheels supporting the grass wiping device section must also be separately switched from side to side, making the operation complicated.

Structure A of the invention Means for solving the problem In the present application, a weeding device in a rotary reaper and a support wheel that supports this weeding device are changed so that when the attitude of the weeding device is switched from side to side, the supporting wheels are reversed. This is an attempt to solve the above-mentioned problems by switching the posture from side to side.

B Example of implementation of the idea Examples will be described with reference to the drawings.

1 is a hand tractor, and a rotary reaper 2 is attached to the front of the hand tractor.

3 is a rotary disk having a cutting blade 3A, and is disposed below the machine frame 2A of the rotary reaper 2.

A plate member 4 is provided above the rotary reaper 2,
One end of the member 4 forms an arcuate edge 5 with grooves 4A, 4B, 4C, and a pivot 6 is implanted at the other end.

A cylindrical body 10 provided with a weeding device 11 above is rotatably attached to a vertical drive shaft 7 for rotating the weeding device 11 via a bearing body 7A, and the cylindrical body 10
An arm 8 having a shaft 9 is fixed below.

The pivot 6 has an arm 12 having a long hole 12A.
A long rod 13 is provided extending to the opposite side of the arm 12, and a support wheel 14 is provided at the end of the rod so as to be vertically adjustable.

The shaft 9 then engages with the elongated hole 12A.

15 is an operating lever, 15A is a locking part, and when the operating lever 15 is raised about the fulcrum 16, the groove 4
When the locking portion 15A is disengaged from A and the cylinder body 10 is rotated left and right, the weeding device 11 rotates, and the support wheels 14 rotate the weeding device 11 about the pivot 6. Rotate in the opposite direction.

17 is a conveyor belt having a protrusion, and 18 is a switching lever for switching the rotation direction of the rotary disk 3 and the conveyor belt 17.

C action Explain along with the effects.

Effect of the invention Next, to describe the action of the invention together with its effects, when the mowing direction is on the right side, it is as shown in Fig. 3. In other words, when the operating lever 15 is rotated in the direction A, the weeding device 11 is moved to the right side. and support wheel 1
4 is a pivot shaft 6 when the operating lever 15 is rotated in the A direction.
It rotates in the opposite direction to the weeding device 11 around .

Then, by operating the switching lever 18, the rotary disk 3 and the conveyor belt 17 are rotated in the direction C.

As a result, the dent corn Z is cut by the cutting blade 3A of the rotary disk 3, conveyed to the right side by the conveyor belt 17, and successively cut down to the right side of the field.

When the mowing direction is to the left, as shown in Fig. 2, if the operating lever 15 is rotated in the direction opposite to that described above (direction B), the weeding device 11 is rotated to the left, and , the support wheel 14 rotates about the pivot 6 in the opposite direction to the weeding device 11.

Then, by operating the switching lever 18, the rotary disk 3 and the conveyor belt 17 are rotated in two directions.

As a result, the dent corn Z is harvested, conveyed to the left side by the conveyor belt 17, and successively cut down to the left side of the field.

Further, when the machine is driven on a public road after finishing the mowing work, the attitude of the weeding device 11 is positioned at the center of the machine body as shown in FIG.

That is, the locking portion 15A of the operating lever 15 is engaged with the groove 4B.

In this attitude, the aircraft width becomes narrower,
Convenient for driving on the road.

Furthermore, by changing the vertical position of the support wheels 14, the height of the cutting blade 3A above the ground can be changed, that is, the crop cutting height can be adjusted.

As mentioned above, in this case, the posture of the weed thinning device and support wheels can be changed with a single operation lever, and since the support wheels are located on the opposite side of the grass thinning device, there is no problem in cutting down the grass, and The cutting height can also be adjusted by adjusting the support wheels up and down.
