Description

[Detailed description of the invention] [Industrial application field] The present invention is equipped with a fertilization device in which a seedling planting arm is attached to the rear of the machine body, and a furrowing device for fertilization is arranged on the front side of the machine body from the seedling planting arm. Regarding walking rice transplanters.

[Conventional technology]

Conventionally, in the walking rice transplanter mentioned above, as shown in Japanese Utility Model Application Publication No. 57-82125, the upper part of the seedling planting arm is opened, so that it is easy to do the work without changing the walking position or position with respect to the machine body. In addition, the condition inside the groove maker could be easily determined by looking through the groove maker from the control section.

[Problem that the invention attempts to solve]

In the case of conventional machines, mud thrown up by the seedling planting arm that moves to plant the seedlings could fly into the control section, making it difficult to control.

An object of the present invention is to make it easy to see through the inside of the groove cutter from the control section and to easily avoid scattering of mixed soil into the control section.

[Means to solve the problem]

The characteristic configuration of the present invention is that in the aforementioned walk-behind rice transplanter with a fertilization device, a mudguard cover is arranged above the seedling planting arm to prevent mud from flowing from the seedling planting arm to the control section, and from the control section to the control section. The mudguard cover is provided with a notch for looking through the groove maker, and a light source for inspecting the inside of the groove maker.The functions and effects thereof are as follows.

[Function] Even if mud is thrown up toward the control section by the seedling planting arm, it can be caught as much as possible by the mudguard cover to prevent it from reaching the control section.

Moreover, regardless of the presence of the mudguard cover, the groove cutter can be seen through the notch from the control section. Furthermore, even if it is difficult for natural light to enter the trencher, it is possible to use a light source to illuminate the inside of the trencher, create a silhouette of the fertilizer flowing inside the trencher, or use the light source as a means of detecting fertilizer clogging. This makes it easier to judge the situation inside the groove cutter.

[Effect of idea]

Not only does the notch open the field of view, but the light source highlights the visible object, making it easy to see inside the furrower from the control section and improve the flow of fertilizer. While it is possible to work efficiently and easily without having to stop work or change your position to judge the situation while accurately grasping the situation inside the groove cutter, the action of the mudguard cover makes it easier to work. Work can now be done more comfortably by making it easier to avoid mud from flying into the control section.

The two fertilizer tanks 11b, 11b are integrally molded so as to communicate with each other at the upper part, and are attached via a support member 14 to a main body frame 15 which also serves as a transmission case. Four trenchers 18a, 18a, 18 are connected to the four fertilizer tanks 11a, 11a, 11b, 11b through a fertilizer feeding device 16 and a fertilizer supply pipe 17, respectively.
b, 18b are the seedling planting arms 7a and 7b.
It is attached to the fuselage side frame 13 or center grounding float 9b via the groove plate 19 in a state where it is located closer to the front of the fuselage and inside the fuselage than the planned seedling planting location by the seedling planting arm 7a or 7b. In addition, a fertilizer feeding device 16 attached to the fertilizer tank 11a on the outside of the aircraft
is driven by transmitting the operating force of the seedling planting arm 7a located on the outside of the machine body through a transmission mechanism 20, and the two fertilizer feeding devices 16, 16 attached to the two fertilizer tanks 11b, 11b on the inside of the machine body are driven by the operating force of the seedling planting arm 7a located on the outside of the machine body. The operating force of one of the two seedling planting arms 7b, 7b is transmitted and driven by a transmission mechanism 21.

In short, each of the four groove makers 18a and 18b expands the width of the groove after the groove cutting plate 19 has been formed for the purpose of advancing the machine near the inside of the machine where the seedlings are to be planted by the seedling planting arm 7a or 7b. A groove is formed as shown in FIG. It is designed to do so.
