DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crop management machine for managing weeding and fertilizer application, and more particularly to a four-wheeled self-propelled tractor or the like when performing management work such as weeding and fertilizer application. For guiding the operation of the management work machine so that the fertilizer can be sprayed on the crops (seedlings grown to about 4 to 5 cm) planted on the ridges, for example, by being provided at the front of the management work machine. About.

[0002]

2. Description of the Related Art Conventionally, when performing management work such as weeding and fertilizer application, a management work machine is used to ensure that fertilizer can be applied to agricultural crops (seedlings grown to about 4 to 5 cm) planted in ridges. As a guiding method for guiding the running, as illustrated in FIG. 4, a disc type or a sword type along the other ridge P is provided at the tip of the arm rod 20 directed sideways from the spreader C mounted on the rear part of the management work machine B. This guide marker 21
While the front wheel of the control work machine B is along the mark line P 'applied along the ridge at 21, the worker uses the control work machine B from the spreader C mounted on the rear to ensure that the fertilizer is sprayed on the crop.
Was guided.

[0003]

However, according to the conventional guidance method, the operator moves the management machine B forward by moving the guidance marker 21 positioned diagonally rearward with respect to the traveling direction along another ridge P. Since the control work machine B must be moved forward while moving, the forward movement of the control work machine B is apt to meander, and there are places where the fertilizer cannot be surely applied to the crops, or the wheel B-1. In particular, there is a fear that the crop may be trampled on the front wheels. Then, since the worker must operate the management work machine B in an unreasonable posture and in a posture that uses nerves, not only the fatigue is severe, but also the work efficiency is extremely poor.

[0004] The present invention has been made in view of such a conventional situation, and an object thereof is to make a management work machine move forward by observing the traveling direction, such as weeding and fertilizer application along a ridge. An object of the present invention is to provide a guidance device for a crop management work machine that enables management work.

[0005]

According to the present invention, in order to achieve the above object, a ruler body of an appropriate length is provided at a front portion of a management work machine horizontally along a ridge extending parallel to a forward running direction thereof. In addition, a mirror that reflects the ruler and the ridge is provided in the range of view from the driver's seat of the management work machine above the ruler. According to such technical means, when performing management work such as weeding and fertilizer application, the worker moves forward while looking forward to the mirror equipped at the front of the management work machine, and places a ruler body above the ridge in the traveling direction. The management work machine can be run while moving along. As a result, the burden on the workers is reduced, and at the same time, the crops (seedlings that have grown to about 4 to 5 cm)
The fertilizer can be applied to the soil.

In addition, the ruler is configured to be adjustable in height according to the growth of the crop. It is preferable that the ruler body is configured to be able to rotate upward. According to such technical means, the height of the ruler can be changed in accordance with the growth of the crop, so that management operations such as weeding and fertilizer application can be performed regardless of the degree of growth of the crop.

[0007]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which a guidance device A of the present invention is provided at a front portion of a self-propelled management work machine B so as to be adjustable in height and to be able to rotate upward,
1 is a ruler body, 2 is a mirror, 3 is a support rod for holding the ruler body 1 horizontally above the ridge P, and 4 is a support for supporting the support rod 3 so as to be vertically movable and vertically rotatable. The height of the ruler body 1 can be appropriately adjusted by moving the support rod 3 up and down with respect to the mounting tool 4 (from the state of the solid line in FIG. Status). Then, the mounting tool 4 is connected to the operating rod 5 mounted on the driver's seat T by the connecting rod 6, and the operating tool 5 is operated to rotate the mounting tool 4 about the pivot portion 7 as a fulcrum. It is configured to be able to change from the guiding posture in which the ruler body 1 is horizontally aligned above the ridge P to the releasing posture in which the ruler body 1 is rotated upward (from the state of the solid line in FIG. 2 to the state of the two-dot chain line). .

The ruler body 1 is formed from a long body having an appropriate cross-sectional shape, such as a bar or a plate, to an appropriate length, and its tip side is bent obliquely upward to prevent the crop M from being caught. It is formed in a substantially sled shape, and its rear end is fixed to the lower end of the support rod 3 to form a substantially L-shape with the support rod 3.

The support rod 3 is made of a square material or the like, and is mounted on the lower part of the front surface of the management work machine B at a distance between the two parallel ridges P so as to be rotatable and connected by a connection rod 8. It is supported by mounting fixtures 4 on both sides via set screws 9 so as to be vertically movable vertically.

The mirror 2 is mounted on the tip of an arm 10 attached forward from the side of the management work machine B, so that the operator can move the ridge P and the ruler 1 along the upper side of the ridge P to the driver's seat T. To make it visible.

[0013] As shown in FIG. 3, when performing the management work using the fertilizer spreader C mounted on the rear part, the worker moves forward while looking at the mirror 2 mounted on the front part of the management work machine B. The management work machine B can be caused to travel while the ruler body 1 follows the ridge P in the traveling direction of travel.
When the management work machine B is moved to another side P, the ruler 1 is rotated upward by the operating rod 5 (from the state of the solid line to the state of the two-dot chain line in FIG. 2). In addition, the ruler body 1 is not damaged by weeds or the like. The release posture in which the ruler body 1 is rotated upward is the same when traveling on a road.

[0012]

The guide device for a crop management work machine of the present invention is constructed as described above, and has the following effects. . When performing management work such as weeding and fertilizer application, the worker moves forward while looking at the mirror equipped on the front of the management work machine and moves the management work machine along the ruler above the ridge in the traveling direction be able to. Thereby, the burden on the worker can be reduced, and at the same time, the fertilizer can be surely applied to the crops.

[0013] By making the height of the ruler variable according to the growth of the crop, management work such as weeding and fertilizer application becomes possible regardless of the degree of growth of the crop.

Therefore, according to the present invention, it is possible to perform the management work such as weeding and fertilizer application along the ridge while observing the traveling direction in which the management work machine is caused to travel forward, so that it is meandering as in the prior art. It is possible to reliably perform the management work such as spraying the fertilizer on the crop without worrying that the farmer will step on the crop or step on the crop, and the management work can be performed smoothly. Therefore, at the same time you can expect a significant improvement in workability,
It is possible to provide a guidance device for a crop management work machine that can expect many advantages such as a great reduction in burden (fatigue) on an operator.
