Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaping section attachment device for a combine harvester.

In other words, in a combine that consists of a reaping section installed in front of a threshing section mounted on a platform supported by crawlers, the reaping section is removably attached to the threshing section side, and during maintenance and inspection, it is necessary to It can be safely supported at a high height, and when it is attached and detached, it is well supported and can be easily attached and detached, so that it can be carried out suitably.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of the entire combine harvester, in which a threshing section A is mounted above a machine stand 2 supported by track frames 7 on both crawlers 1, and a reaping section B is installed in front of the threshing section A. is plant division 8
It has a structure equipped with a lifting case 9, a cutting blade 10, each conveyor (not shown), a vertical conveyance chain 11, etc., and the grain culm is transferred from the vertical conveyance chain 11 at the rear of the reaping section B to the feed chain 12 of the threshing section A. The structure is substantially similar to the conventional structure so that it can be supplied.

A horizontally elongated hitch 3 having a U-shaped side surface is fixed to the upper front part of the machine base 2 by a support frame 13, and locking pins 14, 14 are provided in the vertical direction on both ends of the hitch 3, which opens the front side. Both bolts 15 in the front and rear directions are installed in the rear part of both ends of the hitch 3.
A support shaft 16 supported by the track frame 7 is installed horizontally at the lower front side of the machine base 2, and the lower mounting bracket 17 of the hydraulic cylinder 5 into which the piston rod 5a is inserted is rotated around the support shaft 16. Constructed by connecting freely.

A transmission pipe 18 is installed horizontally at an upper position in the rear part of the reaping section B, and a transmission case 19 extends from the end of the pipe 18 to support and transmit the vertical conveyance chain 11. pipe 18
The reaping part B is supported by a pipe-shaped frame 4 extending obliquely forward and downward from the intermediate part thereof, and is installed so that power can be transmitted to each part.
The upper end side of the piston rod 5a is attached to a support piece 21 protruding from the middle lower surface of the frame 4 so as to be detachably connected to the upper end of the piston rod 5a via a pin 22. do.

A support frame C is connected to the transmission pipe 18, and the support frame C has a side surface L below both metals 23, 23 in which the transmission pipe 18 is rotatably fitted.
Support rods 24, 24 are provided vertically, and cylindrical metals 25, 25 are provided at the rear ends of both support rods 24, 24, into which locking pins 14, 14 can be inserted, respectively, within the hitch 3. The entire reaping section B is connected to the transmission pipe 18 with respect to the support frame C.
It is installed and constructed so that it can rotate around a fulcrum O, which is the axis of the.

One end of a stay 6 is rotatably attached to the lower side of the frame 4 via a support shaft 26, and a plate 6a is attached to the other end of the stay 6. It is installed so that it can be attached by the support metal 27 when turned sideways, but when the stay 6 is installed vertically and the plate body 6a is grounded, the reaping part B
The entire body can be supported in an upright position, and when the reaping part B is raised and the plate 6a is brought into contact with the upper part of the axle case 29 extending from the transmission case 28, the stay 6 supports it in that state. It is installed and configured so that it can be stored.

In addition, in Fig. 6, 30 is a stand for rice storage,
A cylindrical metal 33 similar to the cylindrical metal 25 is integrally installed at an end of a support frame 32 that extends laterally from the lower part of the support legs 31, 31 below the gantry 30.

In addition, in this combine harvester, a side column 34 equipped with electrical equipment, hydraulic equipment, etc. is installed on the side of the reaping part B, and a control column 35 and a seat are installed in the front and rear of the outer side of the side column 34 for riding. This constitutes the driving section.

Therefore, as shown in FIGS. 1 to 3, the cylindrical metals 25, 25 of the support frame C are fitted into the hitches 3, and the locking pins 14, 14, which are inserted into the hitches 3, are fitted into the cylindrical metals 25, 25. At the same time, the bolts 15, 15 are pressed against and fixed to the cylindrical metals 25, 25, respectively, and the tip of the piston rod 5a is attached to the support piece 21.
When the stay 6 is aligned with the side of the frame 4 and fixed with the support metal 27, the reaping section B can be mounted in front of the threshing section A, and the reaping section B can be attached to the front of the threshing section A. The entire reaping section B can be moved up and down while being rotated about the fulcrum O, and the mowing height can be adjusted and the up and down movement during harvesting in the field can be performed in the same way as in the past.

In addition, when the reaping part B is raised high and the inspection and repair is performed by passing under it, the hydraulic cylinder 5 is used to raise the reaping part B high and the stay 6 is placed on the support. If the plate body 6a is kept in contact with the axle case 29 while being removed from the stay 6 and rotated around the support shaft 26, the reaping part B can be stably supported by the support of the stay 6, and the reaping part B can be stably supported. Work can be carried out safely through the area below part B.

When removing the reaping section B, hang down the stay 6 to ground the plate 6a, remove the tip of the piston rod 5a from the frame 4 by removing the pin 22, and then loosen the bolts 15 and 15 to engage them. If the stop pins 14, 14 are pulled out and the machine is moved backward in this state, the reaping section B can be removed while remaining in an upright position, as shown in FIG.

In addition, with the reaping part B removed, as shown in FIG. When the stop pin 14 is inserted into the hitch 3 and the barrel 33 and the bolt 15 is pressed against the barrel 33, a frame 30 is placed on the supply side of the threshing section A.
can be installed in close proximity to each other, and can be configured as a conventional self-propelled self-escape type.

In this way, the present invention provides a combine harvester in which a reaping section is installed in front of a threshing section mounted on a platform supported by crawlers, in which a supporting frame is attached to a hitch installed in the front of the platform. In addition to being removably connected, the rear part of the reaping part is pivotally connected to the support frame so that it can rotate around a fulcrum, and is supported from the crawler side by the frame of the reaping part that extends from the fulcrum part to the front lower part. The hydraulic cylinder is removably connected, and a stay is installed at the rear lower part of the reaping section, which can be attached to the ground or connected to the front side of the machine base to support the reaping section upward. If the reaping section is connected to the hitch, the reaping section can be installed in front of the threshing section in the same way as before and can be moved up and down by a hydraulic cylinder to carry out work.When performing maintenance inspections through the lower section of the reaping section, the reaping section can be raised high. The reaped section can be supported by the stay and the work can be carried out safely.Also, the stay can be grounded and the reaped section can be supported in an upright position by the stay, and the support frame can be The reaping section can be reliably and successfully removed by removing it from the hitch and moving the machine body, and can be attached by performing the reverse operation, and has the advantage of being of a simple structure and being able to be suitably implemented.
