Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural work vehicle in which an accurate running state of a vehicle for agricultural work and a stable working accuracy are ensured, and a function as a drainage and small groove is added. The present invention relates to a vehicle running path in a field.

[0002]

2. Description of the Related Art In so-called management work during the growing period of crops such as pest control work, a technique of setting the traveling position of a vehicle for agricultural work on a fixed path has been already carried out in upland cultivation. However, since paddy fields are flooded, the ground during the growing period is weak, and it is difficult for agricultural work vehicles to travel along a fixed path many times during the growing period of paddy rice, so management work is performed from the ridge. Or it is done with a walk-behind machine. In addition, an attempt to automatically drive a farm work vehicle along a fixed route in a field is made by detecting work traces and crop rows with a tractor, combine, etc. It is the current situation that a general tractor that can travel on a fixed route has not been developed.

[0003]

Therefore, in order to reduce the cost of paddy field agriculture, and further to reduce the burden on the operator, there is a demand for the field management work to be carried on board. or,
In order to efficiently perform combine harvesting in paddy rice harvesting, it is important that the field is dry during the harvesting period.Therefore, during the growing season, the work of manually digging an alum into the field is performed. This labor saving has been demanded because it is laborious.

According to the present invention, an agricultural vehicle cannot go straight without trampling a crop in a field of soft ground such as a paddy field, and management work in a large-scale field requires a great deal of manual labor, and a field ridge is used. The work was intended to be a loose and inaccurate work, and to solve the difficulty of drainage for large-scale fields.

[0005]

In order to achieve the above object, the present invention is directed to a pair of running vehicles having a groove-shaped cross section in which the left and right wheels of an agricultural vehicle stuck in cultivated soil come into contact with each other in a field. A plurality of rows of roads are arranged at predetermined intervals so that the surface of the road is lower than the cultivated soil layer and almost parallel to the ridge of the field. It is characterized in that the water supply port and the water discharge port, which give the function as a small groove for both drainage and use, are communicated with each other.

[0006]

With the above-described structure, the running path in the field of the agricultural vehicle of the present invention can be provided without damaging the crops in the field by the agricultural vehicle.
In order to drive a stable and stable route, the most important function is to drive the wheels guided by the groove, and by using the in-field running route as a drainage channel for drainage management in paddy fields. Can be made efficient without carrying out laborious grooving work during the growing season. In addition, the running path in the field does not affect other work such as cultivated land and harvesting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the accompanying drawings. FIG. 1 is a partial cross-sectional view of an embodiment of the present invention, in which reference numeral 1 is a wheel running path on which a roadbed in a paddy field is reinforced, a groove-shaped section is formed, and left and right wheels of an agricultural vehicle travel. Reference numeral 2 is a cultivated soil layer, 3 is subsoil, and 4a is a wheel of an agricultural vehicle (passenger tractor) 4. In this embodiment, the wheel traveling path 1 has a width of 300 mm, a thickness and a depth of 200 from the cultivated soil surface to the upper surface (traveling road surface).
mm, depth of the cultivated soil layer 2 is 150 mm, vehicle 4 for agricultural work
The wheel-to-wheel distance of the wheel 4a is set to 1200 mm. Among these, the rut distance of the wheels 4a is set in advance according to the size of the tread of the agricultural vehicle 4 to be used.

The wheel traveling path 1 is constructed by simple paving using a cement-based ground improvement agent, and an example of the construction method is as follows. Digging a groove with a depth of about 20 cm with a deep cultivating rotary with an earth removal plate (upcut, plowing width 25 cm).
Remove the soil drainage plate of the deep-cultivation rotary to a depth of about 20 cm from the groove surface.
Crush the soil. A cement-based ground improvement agent is added to a running groove of 5 m.
Add about kg and crush and agitate the soil with a deep-cultivating rotary. The soil is further crushed by a cassette rotary (plow width 32 cm, 2 stations) to a depth of about 10 cm. After squeezing the tractor 2-3 times and crushing, further crushing with a crusher.

The wheel running path 1 is in contact with the left and right wheels 4a of the agricultural vehicle 4 fitted in the cultivated soil layer 2, and its surface is 50 mm lower than the cultivated soil layer 2 and on the ridge of the field. A plurality of rows are arranged at a predetermined interval (10 m in this embodiment) so that they are substantially parallel to each other. or,
The traveling road surface of the wheel traveling road 1 is 50 m below the cultivated soil layer 2.
Since it is set at a low level, work such as tilling, leveling, and harvesting can be performed regardless of the travel route 1, and the roadbed is not damaged by plowing and leveling with a riding tractor, harvesting with a combine, and the like.

Further, as shown in FIG. 1, the wheels 4a of the agricultural work vehicle 4 travel in a state of being fitted in the groove, so that the road 1
Almost no steering wheel operation is required for running inside. In addition,
Naturally, sowing and seedling transplantation are not performed on the wheel traveling path (30 cm width) 1. In the case of paddy rice, it is possible to sow seedlings or transplant seedlings in two rows in the width direction and two rows in the length direction in the field where the distance between the wheels 4a is the distance, in the case of paddy rice. Therefore, the width of the wheel traveling path 1 is equivalent to that between the rice plant stocks, and there is almost no loss in view of planting density.

FIG. 2 is a bird's-eye view of an embodiment of the paddy field according to the present invention, showing traveling of the agricultural work vehicle 4, working examples, and drainage examples. Here, 5 is a water inlet, 6 is a water outlet,
Reference numeral 7 is a drainage channel, and 8 is a boom sprayer mounted on the agricultural work vehicle 4 for performing chemical spraying work for pest control and weeding. The water supply port 5 and the water discharge port 6 are respectively connected to both ends of each wheel traveling path 1 to provide a function as a small groove for both drainage and for field use. Therefore, the water management in the field can be performed easily and quickly. Further, the connecting portions of the water supply port 5 and the water discharge port 6 to the traveling path 1 are targets for introduction and derivation of the agricultural work vehicle (tractor) 4. Further, not only the boom sprayer 8 but also a management work machine such as tilling and weeding can be attached to the farm work vehicle 4 for working.

In the in-field wheel traveling path 1 of the agricultural working vehicle 4 having such a configuration, a working machine such as a boom sprayer 8 is mounted on the agricultural working vehicle 4 so that the wheels 4 a travel on the wheel traveling path 1. While carrying out the control work. At this time, the wheels 4a of the agricultural work vehicle 4 accurately travel along the wheel traveling path 1 while being fitted into the cultivated soil layer 2, and the wheel traveling path 1 is solid, so that the machine body is stable without tilting to the left or right. Then, the vehicle travels on a fixed route, and highly accurate work is performed. Therefore, the crops in the field are not trampled by the wheels 4a and damaged. In addition, the water supply port 5 and the water discharge port 6 are provided at both ends of the wheel traveling path 1.
Since they are communicated with each other, they are used as the drainage channel for the wheel traveling path 1, and the drainage management for the paddy field can be made efficient without carrying out the laborious grooving work during the growing period.

[0013]

As described above, since the running path in the field of the agricultural vehicle of the present invention is installed in the field at a constant interval in the groove type in accordance with the distance between the wheels of the agricultural vehicle, The part of the road surface that strengthens the ground is minimal, and since the vehicle travels using the groove as a guide, it has the advantage of excellent vehicle running stability. It can be applied to various uses. Further, there is an advantage that the traveling path can also function as a drainage small groove for use in the field.
