[Problems to be Solved by the Invention]

The conventional rubber and metal tracks are shown in FIG.
And as shown in FIG. 24, the height h of the shoe body that constitutes the crawler belt.
Was around 5 cm. A device composed of a rubber track and a metal track, which are common track bands, is shown in FIGS. 12 and 25, respectively. For example, as shown in FIGS. 13 and 14, an agricultural riding tractor and a combine represent a state in which the track is submerged in the soil due to the weight of the vehicle. The depth of the standard cultivated soil layer for cultivating work in ordinary paddy fields is basically 15 cm, and the difference of +-is 5
If the height of the footwear is not secured at about 20 cm, the rice straw and mud will be caught in the orbital zone when the track is submerged, causing various problems. In order to deal with the environment, it is necessary to display the height h of the footwear in determining the GL portion appearing on the ground surface.

In the conventional paddy farm work vehicle, the use of the orbital belt type is small. The track type has the drawback of being slower than the wheel type, but it is a transient problem due to the progress of farmland integration in parallel with the improvement of the field infrastructure, and no other major problems are found. I am convinced that low body height is fatal, and that effective use that solves the problem will give a dramatic development to paddy field agriculture.

Regarding the running parts of the main paddy field agricultural work vehicles, there is a problem that must be improved. Particularly, in wetlands, there is a close negative correlation between the undercarriage of the passenger tractor, the paddy field riding management machine, the riding rice transplanter, and the combine undercarriage. is doing. For example, as shown in FIG. 26, when a wheel-type riding tractor is used for work traveling in a paddy field, the wheel-type riding tractor is used for traveling while the wheels are located in the middle of a relatively shallow portion of the cultivated soil layer during cultivation.

However, as shown in FIG. 30, in the case of the riding rice transplanter, the wheels travel while the wheels are in contact with the core soil layer deeper in the cultivated soil layer. As a result, the headland becomes deeper each time the headland turns year by year, hindering the change of steering direction, which adversely affects the work even in the above-mentioned paddy farm work vehicle. As a response to farmers, the shift from 2D to 4WD for wheel-type riding tractors has made it possible to use 6-wheel drive with rear wheels changed from 2 to 4 wheels for passenger rice transplanters. It was

[0008] As a result of this, as a management work after rice planting, as shown in Fig. 31, when using a weeding machine, a fertilizer spreader, a pest control machine, etc. on a paddy field riding management machine, the previous running trace of Due to the influence, the steering becomes unstable and it is difficult to go straight. Also, since the wheels are driven in contact with deep soil, the surrounding rice is buried by the phenomenon of lifting and dropping due to the mud attached to the wheels. After planting rice, it is extremely difficult to drive a 30-centimeter section between adjacent rice stocks without any adverse effect.
Therefore, it is not possible to fully utilize a wide variety of work machines of paddy field passenger control machines, and the work time and the type of work machine used are limited and uneconomical.

For example, in a paddy riding management machine, it is necessary to drastically strengthen the undercarriage in consideration of the advantage that the ground pressure of the track zone is about 1/10 of that of the wheel type. The structure is changed to a mold, the tracker is made higher and the track volume is increased to improve the buoyancy effect, preventing rice straw and mud from being held by it, and improving so that running and steering can be changed without damaging the roadbed. By implementing it, the introduction and use of various work machines will be realized.

As the working machine, weeder, fertilizer applicator, pest control machine, grooving machine, agitator, rotary, carrier, rice transplanter,
It is necessary and important to wear a mower etc. so that it can be used individually and shared. In addition, the average number of days of use of expensive rice transplanters by ordinary farmers for one year is two to three days. In order to operate it more than three times for multiple purposes, the conventional dedicated independent rice transplanter was clearly positioned as a working machine belonging to the paddy riding management machine.
The rice transplanter, which is a working machine, can be easily attached and detached from the riding rice transplanter body.

Further, in the conventional wetland culturing with a riding tractor, in the case of straight-line cultivating work, even a relatively small model can perform cultivating work with an automatic horizontal cultivator and an automatic cultivator. In the case of (1), since the unevenness due to the steering change is large and the vehicle runs under adverse conditions where soft ground overlaps, the previous device does not work well. For example, as shown in FIG. 28, since the shore is hard, the vehicle body inevitably inclines largely in the soft lateral direction on the opposite side, and the automatic horizontal tillage system cannot correct the level when it exceeds the operation allowable limit. The rotary layer tilts and plows the core layer.

Further, as shown in FIG. 27, in the automatic tiller, the front wheels are lifted and the car body travels with a large inclination toward the rear, so that the automatic tiller becomes inoperable.
When it is further tilted rearward, as shown in FIG. 29, the rotary blade of the rotary equipped in the rear part bites into the cultivator in a state of being stuck in the cultivator, which makes traveling impossible. Farmers had no choice but to renew and procure large 4WD large tractors with high horsepower in order to cope with the bad condition of wetland cultivation. However, it is not solved by the introduction of 4WD, and after successive use, the cultivated soil layer continues to become deeper year by year, it is difficult to change the steering direction in the headland, and the uncontrollable state often occurs, and the 4WD is one size larger. The result has to be updated to.

The fact that the transition from 2D to expensive 4WD has become common sense is that the fields of choice of farmers and paddy fields are confused by different technologies, and 1 hectare = 1 horsepower is basic in the field. On the other hand, in the paddy field, it is not uncommon to have a farmer owning 2 hectares of paddy field = 30 horsepower 4WD for the purpose of using a single working machine mainly for tillage and scraping.
There was an unavoidable preference for wetland softlands. Why do we need 30 horsepower, which is 20 times higher than that of fields, in paddy fields! . Therefore, as a drastic structural enhancement of the undercarriage to correct the common sense of infinitely expensive 4WD purchase, as a further technological innovation of the track belt type riding tractor, the above-mentioned track body is increased and the track volume is increased. Buoyancy effect is enhanced, rice straw and mud are prevented from being held, and improvements are made so that traveling and steering can be changed without damaging the roadbed. It can be so.

[0014] In addition, the combine harvesting orbital zone shown in Fig. 14 is used to change the steering direction in the headland, depending on the weather, in the wetland area, because the forward and reverse movements are repeated several times around the same place. By contacting the core soil layer deeper than the cultivated soil layer and moving a lot of soil and excavating the roadbed, the rotation of the cultivating work in the next spring will be hindered and the cultivated soil will not become deeper and shallower year by year. It is not uncommon for rice straw that has been cut with a combine to be trapped inside the chassis along with mud due to the driving of an orbital zone, causing it to become unable to run.

In addition, the track may be damaged by an excessive load on the track due to the phenomenon of underbody entanglement caused by the entrainment of rice straw, and the durability thereof is significantly impaired. The removal work of the rice straw and the mud that has been involved requires a great deal of labor and also the help of repelling the rice straw and the mud by the high pressure pump.
It is a particularly difficult and painful task of human-powered agricultural work. Therefore, as a further technical innovation of the combine orbital zone, the above-mentioned footwear is increased to increase the track volume to enhance the buoyancy effect, prevent rice straw and mud from being held, and drive and run without damaging the roadbed. It is extremely important and necessary to make improvements so that the steering can be changed.

The present invention is directed to a paddy riding management machine, a riding rice transplanter,
Focusing on the need to improve various problems common to undercarriage such as passenger tractors and combine, the structure of the track section is changed to use the track section in the running part, or the track belt footwear for further technological innovation is raised. The purpose of the present invention is to provide an endless track crawler track that enhances buoyancy by increasing the volume of the crawler track to enhance the buoyancy effect.

[0017]

According to a first aspect of the present invention, there is provided a plurality of metal core bars arranged at regular intervals along a longitudinal direction of a rubber track, and a plurality of metal cores are provided under the metal core tracks. On the outer peripheral surface of the endless crawler belt in which a wire is embedded, the height of the crawler belt, which is the protruding portion of the crawler belt formed integrally with the core metal, is higher than that of the conventional crawler belt. Track tracks with increased buoyancy, characterized by a structure in which bolts and reinforcing hardware are used to fix about 2 to 5 times the length.

According to the above, by increasing the height of the shoe body and the volume of the crawler belt, the surface area in contact with the ground is increased and the buoyancy effect can be further enhanced. Also, in order to prevent mud and rice straw from entering the inside of the track when the vehicle is working, ensure that the position of the submerged portion of the track at the site is high enough to be one step above the ground or uneven soil surface. A basic rubber crawler belt is attached to the track device to allow it to run.

According to a second aspect of the present invention, in a tracked track for enhancing buoyancy, a track link outer peripheral surface having connecting holes at both ends and a flat cored bar are integrally mounted, and a lower part of the track link has a height higher than that of a conventional tracker. The buoyancy is characterized by a structure in which about 2 to 5 times the shoe body is fixed with bolts and reinforcing metal, and each is orbitally connected so that it can be freely bent using track pins. Track tracks to enhance.

According to the above, by increasing the height of the shoe body and the volume of the crawler belt, the surface area in contact with the ground is increased and the buoyancy effect can be further enhanced. Also, in order to prevent mud and rice straw from entering the inside of the track when the vehicle is working, ensure that the position of the submerged portion of the track at the site is high enough to be one step above the ground or uneven soil surface. A basic metal crawler belt is attached to the track device to allow it to run.

A buoyancy-enhancing crawler track according to claim 3 is the buoyancy-enhancing crawler track according to claims 1 and 2, wherein when the crawler belt is driven, the space between adjacent track bodies is expanded and contracted. In order to prevent the inclusion of mud and rice straw, etc. at the location where the above is repeated, in order to cope with the deformation of the space, an elastic block is used to attach it integrally with the shoe with bolts and reinforcing hardware, or Tracked tracks that enhance buoyancy, characterized by a structure in which soft elastic bodies are integrally fixed to both sides of the track body.

According to the above, in order to cope with the awkward motion of the rotation of the crawler belt caused by the thick structure of the crawler belt and the change of the space between the crawler body and the crawler body, the continuous space between the crawler body and the crawler body is set. This is a solution method in which holes are filled by combining them integrally by independent elastic blocks. Also, lower the height of either the adjacent footwear or elastic block.

An endless track crawler track for enhancing buoyancy, characterized in that one of a shoe body and an elastic block whose materials are adjacent to each other is softer and has a structure capable of repeating expansion and contraction.

According to the above, if the elastic blocks adjacent to each other have the same hardness, when the crawler belt reaches the circular orbit of the sprocket or idler during driving, the outer peripheral surface of the shoe and the inner surface The trapezoidal volume deforms and expands between the peripheral surfaces, and when a linear trajectory is reached, the trapezoidal volume conversely deforms and shrinks. The solution is to use different hardness or expansion and contraction.

For example, when the elastic block is softer and more expandable than the shoe body, the elastic block has a standard size when the volume of the sprocket or idler at the position of the circular orbit is enlarged. On a straight track that has passed through the track position, on the contrary, it becomes an elastic block that is compressed and deformed by being sandwiched between the shoes on both sides, and the crawler belt is integrally configured without gaps to allow the running action. .

Further, for example, when the footwear is softer and more expandable than the elastic block, the shape of the footwear is a standard size when the volume of the sprocket or idler at the position of the circular orbit is expanded. On a straight track that has passed through the track position, on the contrary, it will be compressed and deformed by being sandwiched between the elastic blocks on both sides, and a track structure will be formed integrally with no gaps for running action.

According to the invention of claims 1 and 2, by increasing the footwear and increasing the crawler belt volume, the surface area of the footwear is increased and the buoyancy effect is enhanced, and even in soft mud soil. Subsidence can be reduced. Further, it is possible to prevent mud and rice straw from being held in the track device. Furthermore, especially when changing the direction of the headland, the separation between the crawler belt and the soil can be carried smoothly, the soil layer which is the roadbed is not damaged, and the movement of the soil can be suppressed. Furthermore, it is possible to further suppress the phenomenon that the mud is held and dropped.

According to the inventions according to claims 3 and 4,
By eliminating the space between adjacent footwear and forming a tightly integrated crawler track, foreign matter such as soil, pebbles, rice straw, etc. is prevented from entering the gap between the connecting parts. it can. Further, by lowering the height of one of the shoe body and the elastic body which are adjacent to each other, it is possible to increase friction and improve running performance. Furthermore, the buoyancy effect can be further enhanced by closely adhering the footwear to each other and eliminating the gap.

According to the inventions according to claims 5 and 6,
By changing the undercarriage of the paddy field riding management machine from the wheel type to the track zone, it is possible to run with various working machines even immediately after rice planting in a soft field, and the usage of the management working machine is greatly improved. Get wider Especially, a weeder as a working machine can be installed immediately after rice planting to enable full-fledged high-efficiency mechanical weeding work. Fertilizer application at the time of fertilization is possible even in a large plot such as 100a plot. By equipping it with a control machine, a wide range of planned control work for pests and diseases can be performed.

Therefore, the conventional dedicated rice transplanter is
If you install other work equipment, if you do not make major modifications,
