Description

[Detailed Description of the Invention] The present invention relates to a machine frame used in a crawler-equipped traveling vehicle such as a combine harvester.

A crawler-equipped vehicle, in which a machine frame formed by a plurality of frame rods in the shape of a well in plan view, is supported by left and right crawler traveling devices, a large amount of mud is carried around by the crawlers when driving in a muddy area. There were defects such as the mud that had been carried around clogging the cross-shaped space in the machine frame, and even being pushed up and adhering to the mounted work equipment, impeding its function.

In order to eliminate this defect, it may be possible to attach a mud prevention plate separately to the machine frame to prevent mud from entering or being pushed up. However, when such a prevention plate is fixed to the frame, if the space between the prevention plate and the crawler becomes clogged with roots or clods of soil, it takes time and effort to remove it because the distance between the prevention plate and the crawler is narrow. resulting in defects.

In view of these circumstances, the present invention provides a bottom plate that closes the cross-shaped space at the bottom of the machine frame directly above the crawler, and provides the bottom plate so that it can be pulled out in the lateral direction of the machine body. By inserting it into the machine frame and covering the cross-shaped space without any gaps at the bottom, the mud carried by the crawler will not be pushed up into the machine frame, and by pulling out the bottom plate, roots that will get stuck between the bottom plate and the crawler. It was devised to make it easier to remove clods of soil, etc.

Hereinafter, an embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a combine machine frame supported by left and right crawler traveling devices 2 and having a reaping conveyance section 3 mounted on the front. A driver's panel 4 is erected in the front part of one side of the driver's seat 1, and a step 5 that constitutes a scaffold is located at the lower part of the back of the driver's seat 6. An engine is housed inside the frame 6a.

The middle divider extends forward from the upper rear, and can be adjusted by moving left and right in accordance with the planting row spacing of the standing grain culms. When located in a valley, guide plates 15, 15 are attached to both sides of the weeding plate 14a hanging from the lower edge of the middle divider 14. The guide plate 15 is formed in a triangular shape, with the front being higher and the rear being lower, narrower at the front and wider at the rear, and the corner 15a at the rear end is close to the peak of the receiving blade 12. The guide plate 15 is designed to prevent straw and grass from entering between the middle divider 14 and the cutting blade device 11 in the upper part of the trough 12.

An auxiliary step 16 is pivotally supported on the outside of the step 5, and is bent into an L-shape when viewed from the front. When this step is rotated upright about the pivot point 5a, one side of the auxiliary step 16 turns inward. At the same time, the upper part of the recess formed in the step 5 is covered, and the substantial floor area of the step 5 is increased.
Furthermore, when the auxiliary step 16 is tilted downward as shown by the chain line in FIG. It is possible to go up and down to step 5 easily and safely.

A radiator cover 17 is provided on the outside of the frame 6a, and has an air window 17a, and a foldable dustproof cover 18 is attached to the outside of the radiator cover 17. The dustproof cover 18 projects laterally when raised by the parallel link action of an upper plate 19 and a lower plate 20 pivotally supported on the radiator cover 17, and can be folded when lowered.

21 is a rear cover, 22 is a front cover, and 23 is an internal swash plate, each of which is screwed onto the radiator cover 17, and is configured to be connected and fixed with bolts 24 when the dust cover 18 is protruded. ing.

During harvesting, the dustproof cover 18 is used with its protrusion, and at that time air is introduced between the front edge of the upper plate 19 and the front edge of the internal swash plate 23, and the dust settles below the internal swash plate 23 and is collected. be done. Also, when driving on the road, remove the bolts 24 and close the rear cover 2.
1. When the front cover 22 and internal swash plate 23 are rotated toward the radiator cover 17, the dustproof cover 18
It can be lowered and folded, reducing the length and width of the aircraft.

Note that the dust cover 18 has a lateral bulge in the center, excluding the upper and lower edges, so when it is folded, air is introduced from this bulge interval, which may impede light-duty operation such as road driving. Never.

As shown in FIG. 2, the machine frame 1 is configured in a parallel grid shape in plan view by vertical frame rods 25 and horizontal frame rods 26, and the parallel cross-shaped space 27 of the machine frame 1 in the area directly above the crawler 2 is as follows. A bottom plate 28 is provided at the bottom of the machine frame 1 and mounted on the lateral side of the machine so that it can be inserted and removed, so that it can be closed and opened at will. Guide rails 29 support and guide the bottom plate 28, and are provided at the bottom of both the front and rear ends of the machine frame 1. Reference numeral 30 denotes a stopper pin, which is provided on the lateral side of the machine frame 1, and when the bottom plate 28 is pulled out, it is inserted into the stopper hole 28a provided in the bottom plate 28.
The bottom plate 28 is fixed by being fitted into the bottom plate, and when the bottom plate 28 is inserted, the side edges of the bottom plate 28 are held down to prevent the bottom plate 28 from popping out. In addition, bottom plate 2
8 is firmly supported and fixed by the stopper pin 30 and the guide rail 29 in the pulled out state.

Next, the operation and effect of the present invention will be explained. When reaping and harvesting work in a field, the bottom plate 28 is first inserted into the machine frame 1 and fixed with the stopper pin 30. When the machine moves forward due to the rotation of the crawler, the grain culms are harvested by the cutting blade device 11 while being subjected to the pulling action of the pulling case 10, and the grain culms are harvested by the cutting blade device 11.
The grains are supplied to the threshing machine 9 by a conveyance mechanism provided in the.
The threshed paddy passes through a paddy hopper 7 and is stored in a paddy bag placed on a paddy floor 8.

When the above-mentioned reaping and harvesting work is sometimes carried out in a muddy area, the mud is carried around by the crawler 2, and the cross-shaped hollow 27 of the machine frame 1 above the crawler 2 is inserted below. Since it is closed by the bottom plate 28, the above-mentioned rotating mud does not push up and accumulate on the machine frame 1.
In addition, since the bottom surface of the bottom plate 28 is smooth without any unevenness,
The carried mud is smoothly returned to the rice field without getting stuck between the crawler 2 and the bottom plate 28. Even if, for example, a root stock or the like is caught between the bottom plate 28 and the crawler 2, it can be easily cleaned and removed by pulling out the bottom plate 28 to the side.

Furthermore, when threshing the headland harvested grain culm, it is sufficient to pull out the bottom plate 28 on the handling port 9a side of the threshing machine 9, and at that time, when the stopper pin 30 is pushed into the stopper hole 28a, the bottom plate 28 is firmly fixed. The grain culm can be fed to the threshing machine 9 by riding on the bottom plate 28, and the above-mentioned feeding operation can be easily performed even if the handling opening 9a has a high ground clearance.

Furthermore, when transporting paddy bags or straw bundles placed in the field using a combine harvester, the bottom plates 28 on both sides should be
The bottom plate 28 can be used as a loading platform.

In this way, the present invention is applied to a crawler-equipped vehicle such as a combine harvester in which a machine frame formed in a parallel cross shape in plan view by a plurality of frame rods is supported by left and right crawler running devices, and the machine frame is installed at a position directly above the crawler. A bottom plate is provided to close the cross-shaped space at the bottom of the frame, and the bottom plate is provided so that it can be pulled out in the lateral direction of the machine body. By covering the bottom of the crawler without any gaps, the mud carried by the crawler will not be pushed up onto the machine frame, and the narrow space between the bottom plate and the crawler can be easily cleaned by pulling out the bottom plate. It is.
