Abstract

PURPOSE:To make turning performance high at the time of working a dry rice-field and demonstrate a large width effect at the time of working in a wet rice-field so as to enable smooth travel by providing a reinforcing member in the state of filling a triangular space between an undercarriage frame and a travel frame so as to reinforce both frames, and windingly mounting a crawler of lug shape formed along the lower face shape of the reinforcing member and undercarriage frame. CONSTITUTION:A T-shape frame 5 is formed into T-shape cross section with a travel frame 4 provided in the center position of an under-carrage frame 3, along the longitudinal direction. A reinforcing member 6 is provided in the state of filling a triangular space part (a) formed at a connection part between the undercarriage frame 3 and the travel frame 4 so as to connect both frames firmly. A crawler 7 has high turning performance since the grounding area is limited to the ground plane 12 in a dry rice-field and a road in spite of being wide. In the case of performing harvesting work in a wet rice-field, the crawler 7 is grounded not only at the ground plane 12 but also at the whole width to demonstrate buoyancy so as to be able to travel smoothly without the undercarriage frame 3 sinking deep.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crawler device for a mobile work machine, and can be used as a combine or the like for working in wetlands.

[0002]

2. Description of the Related Art In a conventional chlora device of this type, it is difficult to run in a wet field while preventing subsidence of a chassis in an endless belt which constitutes the chlora. In particular,
In a combine operation in a wetland, the threshed grains are stored in a Glen tank and stored, and when the amount reaches a predetermined amount, the weight of the entire chassis increases and settling becomes severe. In such a case, the conventional mobile work machine has a problem that it is difficult to escape from the wetland and the work cannot be performed smoothly.

[0003]

The crawler device used for the mobile work machine must exhibit sufficient buoyancy during work on the wetland and can travel without sinking the chassis. In particular, it is required that the weight of the undercarriage increases during work, for example, even if the above-mentioned combine or the like is used, it is possible to always exert buoyancy in the wetland without fail to smoothly travel.

[0004]

The present invention takes the following technical means in order to solve the above problems. That is, in the mobile work machine 2 equipped with the work machine 1, the chassis frame 3 and the chassis frame 3 arranged in the lateral direction are arranged.
A T-frame 5 is constituted by a traveling frame 4 provided so as to project downward in the central portion of the frame 3, and the lower surface of the T-frame 5 travels with the undercarriage frame 3. The frame 4 and the triangular space portion a are provided by being filled and reinforced with a reinforcing member 6, and a crawler 7 having a lug shape conforming to the lower surface shapes of the reinforcing member 6 and the chassis frame 3 is wound. It is a chlora device equipped.

[0005]

EXAMPLE First, the structure will be described. Chassis frame
The grain 3 is configured such that the threshing machine 8 and the grain tank 9 are mounted in parallel, and the grains that have been threshed and sorted by the threshing machine 8 are conveyed to the grain tank 9 for storage.

Reference numeral 10 indicates a discharge auger. The pre-cutting device 11 is configured by integrally integrating a grass body, a cutting device, and a grain culm transporting device, and is connected to the front part of the chassis frame 3 to transport the slaughtered grain culms to carry out the threshing. It is configured so that it can be supplied to the machine 8. The T-shaped frame 5 has a traveling frame 4 provided in the center position of the chassis frame 3 along the front-rear direction, and has a T-shaped cross section.

The reinforcing member 6 is a triangular space portion a formed at a connecting portion between both the chassis frame 3 and the traveling frame 4.
It is provided in a state of being filled so that both are firmly connected.
The crawler 7 is configured so that it can be run by being wound around the drive wheel 12 and the tension wheel 13 by an endless belt made of a rubber material. The crawler 7 has a size that is large enough to fill the portion formed by the chassis frame 3 and the traveling frame 4, and is made wide along the surface shape of the reinforcing member 6.

The crawler 7 has a width equivalent to the lateral width of the chassis frame 3 and has a flat grounding surface 14 with a flat surface for grounding during normal running (dry field or on the road). Reference numeral 15 indicates a wheel. Another embodiment The crawler 7 is constructed by being wound around a drive wheel 12 and a tension wheel 13 and having an intermediate position supported by a roller wheel 15 attached to the traveling frame 4.

At the intermediate position of the crawler 7 in the front-rear direction, the crower guide 16 has a base portion attached to the traveling frame 4 and a hopper 7 having a loop shape from the middle to the tip end portion. When the ground contact side rises along the ridge of the ground, it can contact and guide the inner surface of that portion so as not to derail in the left and right direction.

According to this structure, the crawler device is
Since the crawler guide 16 is provided in place of the rolling wheel to be provided in the middle portion, the structure is simple and inexpensive to manufacture. In addition to that,
Since the crawler device has no rolling wheels in the middle position, the middle part of the crawler is freely deformed along the shape of the ground contact surface when the ridge is crossed when moving from one field to the next. Because it is possible, there is also an effect that the running becomes smooth.

Next, the operation will be described. First, when traveling in the dry field, each of the rotating parts of the machine body is driven to move forward, so that the grounding surface 14 of the crawler 7 comes into contact with the field scene to support the entire chassis frame 3 and to move properly. And
With the forward movement, the mobile work machine 2 performs a weeding action, a raising action, and a reaping action by the front pre-mowing treatment device 11, and conveys the cut culm to the thresher 8 by the conveying device. Supply.

In accordance with such work, the mobile work machine 2 stores the harvested grains in the grain tank 9 in order, so that the weight of the whole is increased, and the weight is 300 kg compared with when the grain tank 9 is empty. The degree becomes heavy. However, since the crawler device has a wide width, it can be supported stably and smoothly. In this case,
Despite its wide width, the la 7 has the characteristics that it has a high turning performance and can exhibit the same function as the crawler 7 with a normal width, because the contact area is limited to the contact surface 12 in dry fields and on the road. It is a thing.

Next, when carrying out harvesting work on wetlands,
Since the mobile work machine 2 is submerged and runs as a whole because the field scene is soft, the crawler 7 has the ground contact surface 12
Not only that, the entire width is in contact with the ground to exert buoyancy, so that the chassis frame 3 does not largely sink and the vehicle can travel smoothly. The mobile work machine 2 is securely supported by the wide crawler 7 even if the harvesting work progresses and the grains are accumulated in the Glen tank 9 to increase the weight, so that the mobile work machine 2 does not sink. , You can continue to work smoothly.

During such work, the T-shaped frame 5 composed of the chassis frame 3 and the traveling frame 5 is formed.
Since the space a formed between the two is reinforced by the reinforcing member 6 to make the entire structure strong, the frame structure has a high durability.

[0015]

As described above, according to the present invention, in a mobile work machine equipped with a work machine, a chassis frame laterally arranged and a central portion of the chassis frame are projected downward. The T-frame is formed by the traveling frame provided as above, and the undercarriage frame, the traveling frame and the triangular space are filled and reinforced with a reinforcing member on the lower surface of the T-frame. Since it is provided with a revolving member and a crawler having a lug shape conforming to the shape of the lower surface of the chassis frame, the swivel performance is high during dry field work and wide during wet field work. It is the one that is effective and can run smoothly.
