Description

[Detailed explanation of the idea] The present invention relates to the structure of a driving section in a combine harvester.

A front reaping section on the left side of the machine is equipped with a threshing section and a straw blowing section behind it, and a step stand and a paddy holder are installed on the front and rear parts of the right side of the machine. Control column A
The seat column B for supporting the seat b is installed at the rear of the combine harvester.
Since the seat column B is installed so as to be rotatable and movable in the front-rear direction, and the seat column B is installed to be rotatable forward in conjunction with the seat b, the position of the seat b can be adjusted in the front-rear direction. At the same time, seat B and seat column B
Since the entire paddy bag can be installed in a storage manner close to the control column A side, and a large space can be created between the paddy holder 3 and the control column A, changing the paddy bag is a one-man job without an assistant. In addition to making it easy to drive and change the paddy bag, the paddy bag can also be mounted on the step stand, and the seat can be moved forward and backward, making it easy to change the seat and seat column to the stowed state. This can be preferably performed with one touch.

Examples shown in the drawings and planes will be described below.

Figure 1 shows a schematic side view of a combine harvester, in which a reaping section 1 is installed on the front left side of the machine, a threshing section 2 and a straw removal section are installed behind it, and a step stand C is installed on the front right side of the machine. A low-level paddy receiving stand 3 is installed behind the step stand C, so that paddy can be received from the paddy tank 4 installed above the paddy receiving stand 3 into the paddy bags 5, and then An engine section 6 is installed on one side, and a crawler 7 is used as a traveling section, and the structure is similar to the conventional structure.

Further, a control column A is installed on the upper front side of the step stand C, and the upper end thereof is equipped with a grip 8 and an operating lever 9, and the upper left side of the step stand C is equipped with an operating lever 10, etc. A side column 11 is installed, and a foothold rod 12 is installed at the lower right side of the step stand C.

An engaging rod 13 is fixedly installed on the upper surface of the rearmost part of the step stand C, and support pieces 14 and 14 are erected on both sides of the part of the step stand C that is forward of the mounting position. 14.
The port rod 15 can be inserted into 14, and the bolt rod 15 is inserted into the front part of the lower part of the case-shaped seat column B.
is inserted so that the seat column B can rotate around the bolt rod 15, and the tightening can be fixed by a wing nut 16 screwed onto the tip of the bolt rod 15. A locking spring 17 that can be detachably engaged with the engaging rod 13 is attached to the locking spring 17.

Further, elongated holes 18, 18 are formed along the upper side on both sides of the upper part of the seat column B, and bolt rods are inserted into support pieces 19 and 19 vertically provided on both sides of the lower surface near the front of the lower surface of the seat column B. 21 is slidably inserted into the elongated hole 18.18, the support cylinder 20 is fitted into the bolt rod 21 part inside the seat column B, and the wing nut 22 is screwed into one end of the bolt 21. The structure is such that it can be tightened securely.

Then, with the seat column B in a vertical position, the locking spring 17 is fitted and locked to the engagement rod 13, the wing nut 16 is tightened, and with the seat b placed on the upper side of the seat column B, the wing nut is When 22 is tightened and fixed, the operator sitting on seat b can perform the operation.

Also, loosen the wing nut 22 and insert the bolt rod 21 into the elongated holes 1B and 1.
By moving the seat b back and forth along line B, the seat b can be moved back and forth and adjusted to suit the physique of the worker.

Loosen the wing nut 22, move the bolt rod 21 to the rear end of the long hole 18°18, rotate the seat b around the bolt rod 21 to align it with the back of the seat column B, while tightening the wing nut 16. When the locking spring 17 is removed from the engagement rod 13 and the seat column B is rotated forward around the bolt rod 15, it will move along the imaginary line in FIG. 1 and as shown in FIG. 5. Seat b and seat box B can be brought to the side of control column A and placed on step stand C to be stored.

Therefore, the operator can operate the step stand C while standing at the rear, and can perform one-man work such as changing the rear paddy bag 5 from that position. It can also be transported by carrying paddy bags.

In this way, the present invention is equipped with a left front reaping section, a threshing section and a straw removal section behind it, and a step stand and a paddy cradle at the front and rear right sides of the machine. A control column A is erected in front of the step platform, and a seat column B for supporting the sheath b) is erected in the rear of the combine harvester. Because it is configured so that the seat column B can be installed so that it can be installed in a forwardly rotating manner in conjunction with the seat b,
The position of the seat can be adjusted in the longitudinal direction, and in particular, not only the seat but also the seat column can be rotated forward, so the entire seat and seat column can be placed close to the control column and installed in a stowed manner. At the same time, a wide space can be created between the paddy cradle and the control column, and these operations can be performed with a touch of the hand. In addition, it is possible to change the paddy bag 5 at the rear while driving from that position, thereby eliminating the unnecessary one-man work of the auxiliary worker for changing the paddy bag. It has the excellent feature of being able to be carried by carrying a bag.
