Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mounting device for a working machine in a combine capable of performing different types of work, in which a work frame for removing snow or removing soil is provided on a harvesting frame of the combine.

[Prior art]

Conventionally, a work device such as a bucket or a dump plate is attached to a reaper frame that has been installed in the front of the combine machine body via a lifting device such as a hydraulic cylinder so that it can be raised and lowered, and snow removal and removal are performed separately from the combine work. It is known to perform different types of work such as earthwork. (Actual public report 54-3003
0) [Problems to be solved by the invention] However, in the working device using the combine as described above, the working device mounted on the reaper frame has a constant mounting angle, or the above mounting angle. Even in the case of making variable, there is a troublesome operational problem that a separate mounting angle adjusting tool is required and the adjusting tool must be manually operated each time.

In view of the above situation, the present invention uses the existing handling depth drive mechanism as a combiner device as an angle adjuster of the work device so that the work device such as a bucket or a dump plate can be lifted and lowered with a small force. It is intended to be implemented for the purpose of providing a machine mounting device.

[Means for solving problems]

In order to achieve the above object, the present invention provides a cutting frame that is rotatably mounted on a machine body, and a handling deep conveyance body that is vertically swung by a drive mechanism. In a combine configured to be pivotally connected by a supported operating link and an operating link pivotally supported by the mowing frame, a working frame such as a bucket or a dump plate is provided at the front end of the mowing frame body connected to the mowing frame. If you attach your body via a pivot,
On the operating piece fixed to the operating link end of the deep handling body,
It is characterized in that the operating rod is pivotally attached to the back surface of the work frame so that the operating rod is connected so as to balance the self-weight rotational force of the work frame with the self-weight rotational force of the handling deep carrier.

[Action]

Therefore, when performing a harvesting operation with the combine of the embodiment configuration of the present invention, the planted culms are sorted by the weeding tool 19 and the grain culms raised by the raising bodies 20 are cut, and the handling depth is properly handled by the transporting body 9. The adjusted grain culm is passed to the feed chain B1 and good threshing work is carried out in the same manner as the conventional one.

And when performing different types of work with the above combine,
The weeding tool 19 is removed, the working frame 23 is attached to this part, and the operating rod 27 for changing the ground posture of the working frame 23 is operated at the end of the operating link 15 of the deep-sea transporting body drive mechanism 10. The piece 15a is pivotally supported.

When snow is removed by the work frame body 23 after being provided in this way, the operating rod 27 is moved to the operating piece 15a by moving the handling depth carrier 9 downward as shown in FIG. It is drawn with, and receiving frame 2
3a can hold snow as the solid line scooping posture and the airframe progress.

Next, when discarding the snow in the receiving frame 23a to another place,
As shown in the figure, after the cutting frame 18 is moved upward by the hydraulic cylinder 6, the deep handling body 9 operates in the shallow handling direction, that is,
By rotating the motor 11 in the clockwise direction, the operating rod 27 is pushed out toward the front of the machine contrary to the above, and the receiving frame 23a
Tilts downward about the axis 25 and emits snow.

The elevation movement of the receiving frame 23a is performed by the operation link 1 of the handling deep carrier 9.
An operating rod 27 pivotally attached to the back surface of the receiving frame 23a is connected to an operating piece 15a fixed to the five end so that the own weight rotating force of the receiving frame 23a and the own weight rotating force of the handling deep carrier 9 are balanced. With this, it can be performed with a small force. As a result, it is possible to avoid an extra load on the motor 11 of the deep-handled carrier 9.

Further, the ground angle of the receiving frame 23a as the work frame 23 can be easily adjusted by setting the position of the drive mechanism 10 in advance, which is effective during the earth unloading work. In the embodiment, the working frame 23 is a cutting frame without the weeding tool 19.
Although the cutting frame body 18 is attached to the portion 18, the cutting frame body 18 may be removed and directly attached to the cutting frame 4.

〔Example〕

Embodiments of the present invention will be described in detail with reference to the drawings. Reference numeral 1 is a combine fuselage in which a mowing device A and a threshing device B are mounted from the front on a machine base 3 equipped with a crawler type traveling device 2, and a driver's seat C is placed on the side of these.

The reaper A has a structure in which a support shaft P fixed to the machine base 3 is
A rear end portion of the mowing frame 4 obliquely provided in the lower front is pivotally supported, and the lower part of the mowing frame 4 is supported by a hydraulic cylinder 6 which is extended and contracted by a lever 5 operated from a driver's seat C.

Then, the handling depth transporter 9 including the seed transporter 7 and the stock transporter 8 can be transmitted to the support shaft P at the lower end of the transmission tool 9a, and the handling depth transporter 9 swings around the support shaft P. Support rotatably.

Reference numeral 10 denotes a drive mechanism for the above-mentioned deep-handled carrier 9, which is configured as follows. That is, 11 is a motor that is equipped with an arm 12 and a connecting rod 13 and is fixed to the mowing frame 4 and is capable of rotating in the forward and reverse directions. The other end of the connecting rod 13 is pivoted between the handling deep carrier 9 and the mowing frame 4. When the motor 11 is normally and reversely rotated by operating the operation tool 17 such as a lever or a switch by connecting it to the pin 16 of the operation links 14 and 15 connecting them, the operation is performed by the operation of the arm 12. The links 14 and 15 are bent and stretched, and along with this, the deep handling body 9
Is rocked up and down to adjust the handling depth. The position shown by the chain line in FIG. 1 shows the shallowest handling setting state of the handling deep conveyance body 9.

Reference numeral 18 denotes a mowing frame body to which a series of mowing mechanisms such as a weeding tool 19, a raising body 20, a cutting blade 21, and a scraping device 22 are attached in the forward direction and which is fixedly mounted on the mowing frame 4.

Reference numeral 23 denotes a work frame body that is detachably attached to the mowing frame body 18 from which the weeding tool 19 has been removed, and is a work frame body for snow removal work in the embodiment.

In this configuration, as shown in FIG. 3, a bucket-shaped receiving frame 23a is rotatably provided between the mounting portions 24 mounted on the mowing frame bodies 18 on both sides via pivot shafts 25, 25, and is pivotally supported above the rear surface thereof. The operating rod 27 that can be extended rearward with the pin 26 is pivotally supported on the operating piece 15a formed at the end of the operating link 15 of the drive mechanism 10 so that the operating rod 27 can be attached to the machine body and easily assembled. Yes.

〔effect〕

As described above, according to the present invention, when a work frame body such as a bucket or an earth shaving plate is attached to the front end of the mowing frame body connected to the mowing frame via the pivot, the work frame body is fixed to the working link end of the handling deep conveyance body. The work piece is pivotally attached to the back surface of the work frame to connect the work rod so that the self-rotating force of the work frame balances with the self-weight rotating force of the deep conveying body. The frame can be raised with a small force. As a result, it is possible to avoid an extra load on the motor of the deep-handled carrier.
