Description

[Detailed description of the invention] The present invention has a pre-reaping processing section and a driving section arranged side by side at the front of a traveling machine equipped with a threshing device, and a collecting section for grain bagging at the rear of the driving section. The side step, which is lower than the operating section step surface, is arranged so as to be switchable between a working position in which it extends laterally and a storage position in which it stands upright on the body side, over the lateral outer part of the frame on which the part is mounted and the lateral outer part of the recovery part. The present invention relates to the step structure of the combine harvester.

When using a combine harvester with the Changki configuration, the following problem occurred when working with the side step up and retracted.

In other words, the reason why the side steps are stored in a vertical position is that when performing the splitting process, the side steps come into contact with the uncut grain culm, worsening the planting posture of the grain culm, or bending the grain culm. In order to prevent this, as mentioned above, when the side step is retracted, the inside front edge of the side step is located on the outside of the frame below the driver, so a gap is formed here. During the middle splitting process, there was a problem in which uncut grain culms got into the middle and damaged the grain culms.

In addition, when using the combine harvester with the Changki configuration, the following problems occurred when working in a working position with the side steps extended laterally.

In other words, a worker who collects grain usually accompanies the side step, but when the worker operating the combine transfers to the operating section via the side step, or from the operating section to the side step. In these cases, as mentioned above, the front end of the side step is located on the outer side of the operating section, which poses a problem in that it is dangerous for the operator to easily step on the step.

The present invention has been made in view of these problems, and it is possible to close the gap between uncut grain culms by rationally arranging a member that closes the gap formed inside the front end of the side step. In addition to preventing the entry of
The purpose is to prevent the worker from stepping off the front end of the side step.

A feature of the present invention is that a member is provided protruding from the upper surface of the front edge of the side step to fill the gap between the front end of the side step and the outer surface of the frame in the upright and retracted position, Its effects are as follows.

In other words, by adopting the above configuration, the space formed inside the front end of the side step during the middle splitting operation is
The grain culms will not get into the side step, and since the above member is provided protruding from the upper surface of the front edge of the side step, the above member will prevent slipping when the worker's foot comes into contact with the front end of the side step. Since the position of the front end of the side step can now be recognized by the tactile sensation of the tip of the worker's foot, it is now possible to prevent the worker from accidentally stepping off the step.

Therefore, compared to the case where a gap closing member is provided on the outer surface of the driver frame and a non-slip member is provided on the side step, the structure is simpler and two different problems can be solved in a single member. This problem could be resolved by installing it.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, a boarding operation section 3 is disposed at the front right side of a fuselage frame 2 equipped with a pair of left and right crawler traveling devices 1, and a grain bagging collecting section 4 is disposed behind this. In addition, a reaping pre-processing section 6 is provided at the front of the machine, in which a threshing device 5 is disposed on the left side of the collecting section, for reaping the planted grain culms while raising them, and for conveying and supplying the reaped grain culms to the threshing device 5. They are connected so that they can be driven up and down to form a combine harvester.

Further, as shown in FIGS. 1 to 4, the grain bagging and collecting section 4 stores the grains from the threshing device 5, and also stores the grains in collection bags 7 disposed below. A dispensing hopper 8, a support rod 9 for suspending and supporting the collection bags 7, a fixed step 10 on which the collection bags 7 are placed, and a top surface of the fixed step 10 facing outward from the fixed step 10. Side step 1 with the top surface at the same level
1 are provided. The rear end of this side step 11 is made to substantially coincide with the rear end of the fixed step 10, and the front part of the side step 11 has a shape in plan view, and the right side part is obliquely cut out in a shape that tapers forward. is manufactured to a size that reaches approximately to the side of the driving section 3, and is attached to the body so as to be swingable about the axis in the longitudinal direction so that it can be stored in an upright position with a structure to be described later.

Next, the swing structure of the side step 11 will be explained. As shown in FIGS. 3 and 4, plate-shaped brackets 12 and 1 are attached to the front and rear outer ends of the fixed step 10.
2 is set upright, and pins 13, 13 are provided protruding from the upper ends of the brackets 12, 12 so that their respective axes coincide with the horizontal axes in the longitudinal direction of the fuselage. , this pin 13,13
plate-shaped locking brackets 14, aligned with each other;
14 are erected. This locking bracket 1
4 and 14 are erected near the inner end of the side step 11 in such a way that the extending portion extends further into the body than the inner edge of the side step 11, and this extending portion extends from the outside of the inside of the body diagonally downward. The peripheral edges 14a, 14a are processed into an arc shape, and the upper ends 14b, 14b of this arc shape part
The side step 11 is attached to the fixed step 10 by inserting the pins 13, 13 into the long holes 14c, 14c.
Furthermore, as shown in FIG.
Outer edge 10a and side step 11 inner edge 11b
The working posture of the side step 11 is maintained by this contact, and by artificially lifting and swinging the outer end of the side step 11, the upper end 14b of the locking bracket 14 is brought into contact with the outer edge 1 of the fixed step 10.
0a so that the side step 11 is maintained in its upright and retracted position. Further, the side step 11 can be released from the upright and retracted position by lifting the side step 11 upward and releasing the lock between the outer edge 10a of the fixed step 11 and the locking bracket 14.

As shown in FIGS. 5 and 6, on the front edge 11a of the side step 11, there is a member 15 formed by bending a plate-shaped body into a triangular shape in side view.
The front edge of the member 15 is aligned with the front edge of the member 15, and the front edge of the member 15 is fixed to the upper surface of the side step 11 in a substantially perpendicular direction. The height of this member 15 with respect to the side step 11 is determined by the width S of the gap formed between the frame 2 below the driving section 3 and the upper surface of the side step 11 when the side step 11 is stored in the upright position. They are roughly matched. This is to close the front opening of the inner space of the front edge 11a of the side step 11 when the side step 1 is in the retracted state. This function prevents the operator from slipping when getting on or off the boarding/driving section 3 via the front edge 11a of the side step 11 when the side step 11 is in an extended state. have.
