Description

[Detailed description of the invention] The present invention places a driving part at the rear of the machine and a reaping part at the front, and connects the driving part and the reaping part via the machine frame. A binder that is provided between a wheel case that can be vertically swung on a fulcrum and the frame, and a mechanism that can change and fix the wheels in multiple stages in the vertical direction, and a spring that biases both in a direction to separate them from each other. Regarding reaping and harvesting machines such as.

This type of reaping/harvesting machine is equipped with a spring between the wheel case and the machine frame that biases both of them in the direction of separating them from each other, so the height of the wheels can be adjusted depending on the degree of settling of the wheels. When adjusting the height), even if the position of both (wheel case and frame) is released from the above mechanism,
The machine frame does not drop suddenly around the grounding point on the cutting section side, and can be maintained at the same height or close to it when fixed, making it possible to input a machine frame with a large weight. This has the advantage that the wheel height can be easily adjusted with little effort without the need for support.

The present invention has the above-mentioned advantages, and by rationally improving the spring, deformation and damage of the locking pin of the mechanism are suppressed as much as possible, and the durability of the mechanism is improved. The purpose is to make the wheel stable in the upper part within its vertical position change range when the spring is applied and the position fixed by the mechanism is released. It is characterized by being composed of a spring constant such that the

In other words, this type of reaping harvester is rarely used with the wheels fixed at the upper part within the vertical position change range when reaping in general fields or driving on the road. By focusing on many points, the spring is configured with a spring constant that allows the wheel to be stably positioned in the frequently used upper part, so that the mechanism can be easily used when working at the frequently used wheel height. Since the shear stress applied to the locking pin, etc. can be reduced to zero or very low, deformation and damage of the locking pin, etc. due to this shear stress can be sufficiently suppressed, and the durability of the mechanism can be improved. It has become easier to maintain good wheel height adjustment over a long period of time as described above.

Embodiments of the present invention will be described below based on the drawings.

Figures 1 and 2 show a binder, which consists of an engine 2 and a transmission case 3 connected laterally to the rear of a pair of left and right drive wheels 1.1 disposed at one location in the front and back direction when viewed from the side. A driving part 4 is provided, and this mission case 3
and the axle I of the drive wheels 1, 1 at its front end.
A and IA are supported by a case 5, which is mounted so as to be swingable up and down around a horizontal axis 4 which is also an input axis at its rear end, and which is connected between the upper end of the transmission case 3 and the driving wheels 1, 1. A reaping section 7 is rigidly connected to the tip of a pipe-shaped fuselage frame 6 that extends forward through the center of the frame.

Further, a steering bundle 8 is installed rearward and upward from the fuselage frame 6, and between the wheel case 5 and the fuselage frame 6, the drive wheels 1.1 are repositioned and fixed in four stages in the vertical direction. possible mechanism 9 and a spring 10 that biases both 5 and 6 away from each other.
and.

The reaping section 7 includes a device 11.11. that pulls up the two planted stem culms rearward and upward. A clipper-type reaping device 12 that cuts the base of the raised stem culm, a device 13 that transports the cut stem culm horizontally to the side of the machine body, and a device 13 that transports the cut stem culm horizontally to the side of the machine body, and a device 13 that transports the cut stem culm horizontally to the side at regular intervals. It is composed of a device 14, etc., which focuses and bundles and discharges.

The mechanism 1 is constructed as follows.

That is, as shown in FIG. 3, four locking holes 16 are formed in the bracket 15 provided near the front end of the wheel case 5 at appropriate intervals in the longitudinal direction. A pipe-shaped arm 17 is pivotally mounted, and the arm 17 is fixed to the fuselage frame 6 so as to protrude upward through a through hole 18 a of a member 18 . A lock pin 19 is provided which can be freely engaged and detached from the lock pin 16, and the spring receiver fixed to the lock pin 19 is connected to the member 19A, and the spring receiver fixed to the fuselage frame 6 is connected to the member 20 by the lock pin 19. A spring 21 is interposed that biases 19 in the engaging direction.

Further, the lock pin 19 and the grip portion 8 of the bundle 8
The operation lever 22 mounted on the arm 17 is connected to the operation lever 22 attached to the arm 17 via the operation wire 23, and the above-mentioned attachment
The above-mentioned spring 10 is attached between the base end 17A and the base end 17A.
By selectively engaging the locking pin 19 with the locking hole 16 of the arm 17, the wheels 1, 1 can be positioned in four stages, up and down. It consists of

With the spring 10 biasing the body frame 6 and the wheel case 5 in the direction of separating them from each other, the wheel 1 is released from the position fixation by the mechanism 9.
, 1 are stably positioned at the most frequently used uppermost position within the range of vertical position change.
It is constructed from a spring constant that allows it to be stably positioned at a position corresponding to .

Note that among the locking holes 16 of the arm 17, if the second locking hole 16 from the bottom is used frequently, this locking hole 16 is located at a position corresponding to the lock pin 19. It is preferable that the spring constant of the spring 10 is configured so as to provide a stable position.

FIG. 4 shows an improvement of the above embodiment, in which the spring 10
A member 24 for receiving and supporting the lower end of the arm 1
7 are screwed together so that the position can be changed in the longitudinal direction.

In this case, the wheel 1.degree. 1 can be reliably and stably held at the set height position, regardless of manufacturing errors or deterioration of the spring over time.
