The longitudinal screw conveyors 11, 11 are dividedly set up on the left and right outsides of the driving seat 4, thus not getting impedimental in feeding seedling tables 15a, 15b with seedlings.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a paddy field working machine with a fertilization device, more specifically, a working device for planting or direct sowing in multiple rows is connected to the rear of a traveling machine body so as to be able to move up and down, and A paddy field working machine with a fertilizing device, in which the working device is equipped with a fertilizing device that applies fertilizer to each row, and a fertilizer replenishment tank for the fertilizing device is located at a high place near the driver's seat and supported on the traveling machine body. Regarding.

[Conventional technology]

Conventionally, as the rice paddy work machine mentioned above, for example, the Utility Model 59-
A technique is known in which a lifting device is provided at one location on the left and right sides of the machine just behind the driver's seat, such as in a rice transplanter shown in Japanese Patent No. 73130.

With this technology, fertilizer can be supplied to multiple fertilizer application devices using one lifting device, so the driver's seat that supports this lifting device can be rotated around the vertical axis to supply fertilizer to two locations on the left and right. The fertilizer was pumped into the tank.

[Problem to be solved by the invention]

However, the driver's seat had to be moved each time the fertilizer was transferred to the fertilizer supply tank, which was troublesome.

In order to simplify the structure, if one wide fertilizer replenishment tank with multiple fertilizer discharge parts is installed for multiple rows, the fertilizer in the replenishment tank may be Since the amount of fertilizer that can be stored in the replenishment tank decreases, it is difficult to adopt a method of providing one fertilizer replenishment tank.

Furthermore, since the lifting device is located immediately behind the driver's seat, the lifting device gets in the way when replenishing seedlings, making it difficult to perform seedling replenishment work.

An object of the present invention is to provide a paddy field working machine with a fertilization device that does not have the above-mentioned disadvantages even though the fertilizer supply tank is supported by the machine body.

[Means to solve the problem]

In order to achieve the above object, the present invention provides the paddy field working machine with a fertilization device described at the beginning, in which a lifting device for lifting the fertilizer to the fertilizer supply tank is disposed at the outside of both the left and right sides of the driver's seat. The characteristic configuration is that

[For production]

According to the above configuration, (a) When fertilizer replenishment tanks are installed in two locations on the left and right,
Since the lifting device can be fixedly arranged for each supply tank, there is no need to move the driver's seat. Since there is an outlet for the lifting device, the fertilizer can be stored in a more even state than before, and the actual amount of fertilizer stored in this replenishment tank can be significantly increased compared to before. can.

Furthermore, (c) the lifting device is located on the outside of both sides of the driver's seat, so the lifting device does not get in the way too much when replenishing seedlings to the seedling stand.

〔Effect of the invention〕

Therefore, due to the effect of (a), work efficiency can be improved, and (
Due to the effect of (b), the number of fertilizer replenishment tanks can be set in various ways, increasing the degree of freedom in design, and (c)
The efficiency of seedling replenishment work will be improved by this action.

Furthermore, since the lifting devices are independently located at two locations, there is an advantage that it can be used for paddy field work in which two different types of fertilizers are applied at the same time.

〔Example〕

A case where an embodiment of the present invention is applied to a riding rice transplanter will be described below.

As shown in Figure 1, a pair of left and right drivable front wheels (1
), rear wheel (2), driving unit (3), spare seedling stands (15a) and (15b) on both left and right sides of the drive unit (3), and handle (14).
) and a driver's seat (4), a seedling planting device (5) is attached to a cylinder (6) and a four-speed link mechanism (7).
The two rice transplanters are connected to each other so that they can be raised and lowered, and are configured to transmit power from the traveling body to the seedling planting device (5), thereby creating a riding-type rice transplanter capable of planting six rows.

At the rear of the seedling planting device (5), a fertilizing device (8) is provided that applies fertilizer at the same time as seedling planting.
) is supported by the traveling aircraft near the driver's seat (4).

The fertilizer replenishment tank (T) consists of main tanks (9), (9) located immediately behind both sides of the driver's seat (4), and a sub tank located at a high location above the main tanks (9), (9). (
The sub-tank (10) is supported by two vertical screw conveyors (11) and (II) that transport the fertilizer from the main tank (9) to the sub-tank (10).

As shown in Figure 2, two vertical screw conveyors (
11), (11) are distributed to the left and right sides of the driver's seat (4), and the roof is installed above the driver's seat (4) using these two vertical screw conveyors (11) as supports. (12) is the installation.

The sub-tank (lO) and the fertilizing device (8) are connected to each other by an extendable supply tube (13) to allow the seedling planting device (5) to move up and down.

[Another example]

1 sub-tank (10), 1 vertical screw conveyor (1
1) and (11) may be provided, and also,
It is also possible to add three vertical screw conveyors (11).

4 The present invention may also be applied to paddy field working machines.

Furthermore, the lifting device (11) may be configured with a belt conveyor, an air pressure feeding device, or the like.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
