Description

[Detailed Description of the Invention] The present invention relates to an agricultural working machine, and relates to an agricultural working machine that can perform various agricultural works with a single working machine.

In general, when performing agricultural work, such as forming drainage ditches, weeding cultivated crops, underground work, and digging up seedlings, conventional methods have been conducted according to the purpose of each work. It is customary to select a suitable working machine and then use that working machine.

However, in such cases, a dedicated work machine must be prepared for each type of work, which is not only a heavy burden both economically and in terms of storage space, but also extremely inconvenient in terms of management and handling. There is a drawback.

The present invention has been developed in view of the above points, and allows a single agricultural machine to be used for multiple purposes by attaching and detaching the upper working body, thereby saving economical and storage space.
Furthermore, it is possible to provide an agricultural machine that is easy to manage and handle, and can perform good work.

Next, an embodiment of the present invention shown in the accompanying drawings will be described.

In the figure, reference numeral 1 denotes a main frame with a length extending in both directions, and the transmission 3 is mounted at the rear lower part of the main frame 1 in the approximately central part via the frame 2 in its longitudinal direction. The transmission 3 is mounted so as to be adjustable in position, and connecting frames 4 for a tractor (not shown) are provided on both sides of the transmission 3 and protrude from the front of the main frame 1.

Further, a work body support frame 6 is attached to the rear lower part of at least one side of the main frame 1 via a frame 5 so as to be adjustable in position in the length direction and detachable.

Also, brackets 7 are provided at the rear lower part of both ends of the main frame 1.
8 are removably attached to each bracket 7.
Outer end portions of drive shafts 9 and 10 protruding parallel to the main frame 1 as output shafts from the transmission 3 are rotatably supported between the transmission 8 and the transmission 3.

In this case, the drive shaft 9 on the negative side is rotatably suspended horizontally so as to pass through the front part of the work body support frame 6, and the drive shafts 9 and 10 on both sides have, for example, a regular hexagonal cross section. It is formed as a square shaft.

The work body support frame 6 has a substantially U-shaped side frame 11 extending rearwardly, and the - side drive shaft 9 is rotatably passed through the front part of the side frame 11. At the same time, a middle part of the vibrating shaft 13 is supported via a horizontal shaft 12 in the middle part of the side frame 11 in the front-rear direction, so that it can swing freely in one direction. The roller 14 is rotatably mounted on a shaft, and a pressure spring 17 is hung between the upper end of the vibrating frame 13 and a column 15 erected at the upper rear end of the side frame 11 via a guide rod 16. Furthermore, a fixed frame 18 is formed to protrude from the rear lower part of the side frame 11.

The passive roller 1 in this work body support frame 61 is
4 is in contact with an eccentric cam 19 as a vibration mechanism which is removably fitted and fixed to the drive shaft 9, and a subsoil crushing body as an upper working body is provided at the lower end of the vibration frame 13. 20
is removably attached via the support blade 21, and
A bullet-shaped body 22 as an auxiliary working body is detachably attached to the lower end I of the fixed frame 18 via a supporting blade body 23.

In the gamma vehicle constructed in this way, the main frame 1 is connected to a tractor (not shown) via the connection frame 4, and when power is transmitted from the power output shaft of the tractor to the input shaft 3a of the transmission 3, the transmission 3
Power is transmitted to the drive shafts 9 and 10 through the rotation of the eccentric cam 19 and the pushing of the passive roller 14 against the eccentric cam 19, which causes the vibration frame 13 to move forward and backward with the horizontal shaft 12 as a fulcrum. The subsoil crushing body 20 is vibrated back and forth accordingly.

In this state, the subsoil crushed body 2 is advanced through a predetermined field.
0 and the bullet-shaped body 22 perform subsoil crushing work and underdrain formation work.

For example, in culvert formation, etc., the subsoil crushed body 2
0 and the bullet-shaped body 22 should be positioned behind the tractor wheels of the towing tractor, the attachment to the main frame 1 may be changed by changing the attachment position of the frame 5 through the work body support frame 6. The positions of the subsoil crushing body 20 and the bullet-shaped body 22 in both directions can be changed, and in this case, the attachment and detachment of the brackets 7.8 to the main frame 1 and the insertion and insertion of the side frames 11 to the drive shafts 9 and 10 are possible. By also adding a release operation, the work body support frame 6 can be moved from the position shown by the solid line in FIG. 1 to the position shown by the chain line,
Further, the position of each work body support frame 6 can be varied within a range of 9 degrees 10 degrees for each drive shaft.

It should be noted that several work body support frames 6 may be installed on both sides of the main frame 1.

Next, FIGS. 2a and 2b show an upper working body and an auxiliary working body according to another embodiment, 24 indicates a crushing blade body as the upper working body, 25 indicates a cultivating claw body, The crushing blade body 24 and the cultivating claw body 25 are each removably attached to the vibration frame 13 and fixed frame 18 of the work body support frame 6 via plates 26 and 27,
It is used for inter-tillage weeding work, etc.

Moreover, what is shown in FIG. 3 is a digging blade body 28 as an upper working body according to still another embodiment 1, and this digging blade body 28 has side plate portions 29 erected on both sides thereof. The side plate portions 29 on both sides serve as vibration frames in a pair of work body support frames 6 (for example, the portion shown by a solid line and the portion shown by a chain line in FIG. 1) disposed on both sides of the main frame 1. It is set by detachably attaching it to 13,
For example, it can be used for digging up seedlings and the like.

According to the first aspect of the present invention, the workpiece supported by the workpiece support frame via the vibrating frame can move forward while vibrating to reliably perform the work upwardly, and the vibrations cause resistance to the soil. In other words, the traction resistance can be reduced, and the work body support frame is attached to the main frame so that its position can be adjusted in both directions, and the upper work body is detachably attached to this work body support frame. By selecting and setting the overhead work equipment to be installed as necessary, the installation position can be adjusted and changed to reliably perform various types of overhead work according to the purpose of the work. By selecting and combining one of these upper working bodies according to the purpose of work, a desired agricultural working machine can be easily configured, and one agricultural working machine can be used for multiple purposes. Since it is not necessary to prepare a different agricultural working machine for each work, it is economical, and storage space, management, and handling are also easy, and therefore, a good agricultural working machine can be provided.
