Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direct sowing machine using a rice transplanter.
The present invention relates to a technology for improving the weight balance of an airframe.

[0002]

2. Description of the Related Art As a direct sowing machine using a rice transplanter, a direct sowing device is used by utilizing a fertilizing device supported at the rear of a seedling planting device as disclosed in Japanese Patent Application Laid-Open No. 9-37612. It is known.

[0003]

The rice transplanter has a structure in which a heavy planting section equipped with a seedling mounting table and a seedling planting device is connected to the rear of the machine through a lifting link mechanism. It tends to have a heavy rear balance, and a large diameter is used to reduce the contact pressure so that the amount of sinking of the rear wheel in the field is not excessive.

In the above publication, a fertilizer application device used as a direct sowing device is attached to a seedling planting device. Therefore, there is still a tendency of backward balance and there is room for improvement. As a direct sowing machine equipped with a fertilizing device so that fertilization can be performed at the time of direct sowing, a device disclosed in Japanese Patent Application Laid-Open No. 9-74821 is known. In this device, both a direct sowing device and a fertilizing device are used. Since both are mounted on the planting portion, the above-mentioned rear balance is further enhanced.

An object of the present invention is to provide a direct sowing machine using a rice transplanter,
The configuration is such that the front-rear balance can be improved.
Further, a direct sowing machine with a fertilizer applicator also has an object in improving the front-rear balance.

[0006]

[Means for Solving the Problems]

[Configuration] The first invention is to dispose a direct sowing device including a seed paddy hopper and a seed pad feeding mechanism between front and rear of a seedling planting device behind a traveling machine body and a driver's seat, and the seed paddle fed from the seed pad feeding mechanism. Is provided with a transport path for wind-transporting the seedlings to the seedling ditching device arranged in the seedling planting device at equal pitches in the left-right direction.

According to a second aspect of the present invention, in the first aspect, a fertilizer application device including a fertilizer hopper and a fertilizer feeding mechanism is supported by a seedling planting device at a rear side of a seedling mounting table, and the fertilizer fed from the fertilizer feeding mechanism is provided. Is guided to a fertilizer grooving device provided in the seedling planting apparatus.

According to a third aspect of the present invention, a fertilizer applicator including a fertilizer hopper and a fertilizer feeding mechanism is provided between a front and a back of a seedling planting device behind a traveling machine body and a driver's seat, and the fertilizer fed from the fertilizer feeding mechanism is provided. Is provided with a transport path for wind-transporting to the fertilizer cultivator provided in the seedling planting device, and a direct sowing device comprising a seed paddy hopper and a seed pad feeding mechanism is supported by the seedling planting device at the rear side of the seedling table. In addition, the present invention is characterized in that the seed rice unreeled from the seed union feeding mechanism is guided at equal pitch in the left-right direction to a seed rice cultivation groove device arranged in the seedling planting apparatus.

[0009] A fourth invention is the invention according to the second or third invention, wherein:
It is characterized in that both the seed paddy and the fertilizer are guided to the seed paddy cultivator, and the fertilizer pit is omitted.

According to the first aspect of the present invention, the space between the planting device behind the traveling machine and the front and rear of the driver's seat is focused on, and the direct sowing device is disposed there. The machine center of gravity is shifted forward as compared with that of the former publication which supports the direct sowing apparatus. Although the transport path between the direct sowing device and the seed paddy cultivator becomes longer than before, it can be transported favorably by wind power transport. And
By connecting a seed cultivator for supplying seeds to a field arranged at equal pitches in the right and left of the seedling planting device and a seed unreeling mechanism by a downflow path, the seeds in the hopper arranged on the aircraft are planted. At the attachment device site, it can be supplied to the field at equal intervals.

According to the second aspect of the present invention, the fertilizer applicator is supported by the seedling planting apparatus as in the prior art. However, since the direct sowing apparatus is supported by the machine body, both the fertilizer applicator and the direct sowing apparatus are planted. Compared with the latter publication, which is supported by the planting device, the machine center of gravity can be moved forward.

According to the third aspect of the present invention, the direct sowing device is supported by the seedling planting device and the fertilizer application device is supported on the body between the seedling planting device and the driver's seat. Both the apparatus and the direct sowing apparatus allow the machine weight center to be moved forward as compared to the latter publication in which the seedling supporting apparatus is supported. Although the transport route between the fertilizer and the fertilizer producing device is longer than before, it can be transported favorably by wind power transport. Also, by supporting the direct sowing device on the seedling planting device, the length of the seed rice transport path is relatively short, so that there is almost no or little damage to the seed rice outer skin due to contact with the inner wall of the transport path, and it is good. This is advantageous in terms of advantageous germination.

According to the fourth aspect of the present invention, since both the seed paddy and the fertilizer are supplied to the field from the seed paddy cultivator, the fertilizer pit can be omitted and the cost can be reduced accordingly. Since the seed paddy cultivation devices are arranged on the left and right at equal pitches, both the fertilizer and the seed paddy can be supplied to the field at equal left and right pitches. Then, depending on the type of fertilizer or seed rice, such as a quick-acting fertilizer, it may be desirable to supply the seed rice and the fertilizer close to each other, and the structure of the present invention is effective in such a case.

[Effect] In the direct sowing machine according to the first aspect of the present invention, (a) a direct sowing device which can be equipped with a direct sowing device with little modification by using a rice transplanter is realized in a preferable state in which the rear balance as an airframe is improved. We were able to.

According to the direct sowing machine of the second aspect, (b) the above-mentioned effect (a) can be obtained while making it possible to perform fertilization simultaneously with direct sowing.

According to the third aspect of the present invention, there is provided a direct sowing machine which can be equipped with a direct sowing device with little modification by using a rice transplanter, in a preferable state in which the rear balance as an airframe is improved, and a germination rate. The fertilizer can be fertilized simultaneously with direct sowing in an advantageous condition.

According to the fourth aspect of the present invention, the cost can be reduced by omitting the fertilizer cultivator, so that the advantage (b) or (c) can be obtained while being economically preferable. .
