Description

[Detailed explanation of the invention] [Industrial application field] The invention relates to a traveling paddy field working machine.
The present invention relates to a walk-behind paddy field work machine whose body is equipped with a device for fertilizing or sowing.

[Conventional technology]

BACKGROUND ART Conventionally, as a paddy field working machine constructed as described above, a rice transplanter equipped with a fertilization device is known, for example, as shown in Japanese Utility Model Application Publication No. 185421/1983.

In this rice transplanter, a hopper and a feeding mechanism constituting the fertilization device are provided above the hood, which is located at a relatively high position relative to the machine body.

[The problem that the idea attempts to solve]

However, when the fertilizer application device is disposed as in the prior art, the center of gravity of the aircraft becomes high, so there is room for improvement in terms of stability of the aircraft.

Therefore, it is possible to improve the stability of the aircraft by housing the hopper, feeding mechanism, etc. inside the bonnet. If the feeding mechanism is simply housed in the hood, it is expected that the operation tool for adjusting the feeding amount provided in the feeding mechanism will be difficult to handle.

In particular, when the operating tool is provided on the side of the feeding mechanism as in the cited example, the operating tool cannot be operated unless the bonnet is structured to open wide.

The purpose of this invention is to provide a walk-behind paddy field work machine in which the feeding mechanism is located in a position that fits within the bonnet to improve the stability of the machine, while at the same time eliminating the difficulty in handling the operating tool for adjusting the feeding amount. It's in the point of gaining.

[Means to solve the problem]

The characteristic configuration of the present invention is a traveling type paddy field working machine that is equipped with a bonnet for a driving part and a fertilizing or sowing device in which a hopper is connected to the upper part of a feeding mechanism. The bonnet is supported so as to be swingable and openable, and the fertilizing or seeding device is dropped into the opening formed in the bonnet, and the feeding mechanism is housed in the bonnet, and the feeding mechanism is located at a position opposite to the axis of the feeding mechanism. The device is equipped with an operating tool for adjusting the feeding amount, and its functions and effects are as follows.

[Effect]

According to the above characteristic structure, when opening the bonnet, the operating tool can be operated from the opening side (front side).

In other words, the center of gravity is lowered by lowering the entire mechanism into the bonnet until it bites into the bonnet. By providing the operating tool on the side that is further away from the bonnet, the operating tool can be moved by swinging the bonnet at an opening that is small enough to expose the operating tool without having to swing the bonnet so far as to expose the entire feeding mechanism. can be operated.

[Effect of idea]

Therefore, it is possible to improve the stability of the aircraft by lowering the center of gravity by locating the device for fertilizing or sowing so low that it cuts into the bonnet, without requiring a structure that opens the bonnet widely. We were able to provide a walk-behind paddy field work machine that allows you to easily handle the operating tool for adjusting the feeding amount.
