Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a pair of left and right furrowers for separately supplying fertilizer near the seedling planting site by a pair of left and right seedling planting arms, and A pair of left and right fertilizer delivery devices that supply fertilizer to each container separately are arranged at a location located forward of the machine body from the seedling planting arm,
a swinging link that is rotatably attached to the drive shaft in the longitudinal direction of the machine body of each of the left and right fertilizer feeding devices and located above the seedling planting arm;
A walking type with a fertilization device in which the left and right fertilizer feeding devices and one of the seedling planting arms are interlocked and connected by an interlocking mechanism including a push-pull interlocking rod in the lateral direction of the machine body, in which the pair of left and right swinging links are interlocked and connected. Regarding rice transplanters.

[Conventional technology]

In the walk-behind rice transplanter described above, by opening the entire rear of the interlocking mechanism, it is possible to easily judge the fertilization status by looking through the area of the interlocking mechanism from the rear of the machine to the furrower and its vicinity. I was doing it.

[Problem that the invention attempts to solve]

In the conventional case, when judging the fertilization status visually from the rear of the machine, the transmission movement of the interlocking rod is a linear movement that is difficult to see, whereas the transmission movement of the swinging link is a oscillating movement. Since the swing link is easily visible, the swing link comes into view and its reciprocating movement confuses the eye, making judgment difficult or inaccurate.

An object of the present invention is to modify the device so that the visual judgment can be made accurately and easily regardless of the operation of the interlocking mechanism.

[Means for solving problems]

The characteristic configuration of the present invention is that in the above-mentioned walk-behind rice transplanter with a fertilization device, the cover covering the rear of the left and right swinging links is arranged such that the lower ends thereof are located at the same or almost the same level as the lower ends of the swinging links. The functions and effects are as follows.

[Effect]

Due to the above-mentioned shape of the cover, a space is secured below the cover to see through the groove and its vicinity from the rear of the aircraft, and while the cover does not obstruct the line of sight as much as possible, the cover allows the swing link to be seen clearly. It is possible to prevent the reciprocating operation of the swing link from causing a decrease in visual attentiveness by covering it to prevent it from entering.

[Effect of idea]

Because there is no obstruction to the line of sight and the ability to concentrate on visual inspection without being hindered by the reciprocating movement of the swinging link, it is now possible to accurately and easily judge the fertilization status from the operating position. I am now able to work more efficiently while accurately understanding the situation.

〔Example〕

As shown in FIG. 1, a pair of left and right running wheels 1, 1 are mounted so as to be freely raised and lowered via a swingable transmission case 2, and an engine 3, this engine 3, and a fuselage frame (not shown) are attached. A pair of left and right seedling planting arms 6a, 6 are installed at the rear of the self-propelled aircraft, which is equipped with a bonnet 4 that covers the hood 4, a control handle 5, etc.
A seedling stand 7 for supplying seedlings is attached to these seedling planting arms 6a and 6b, and a grounding float 8 is attached to the lower part of the self-propelled body. The device is equipped with a fertilizer tank 9 which is located in front of the pair of left and right seedling planting arms 6a, 6b and behind the engine portion of the bonnet 4. ,2
This walk-behind rice transplanter is equipped with a fertilization device that can perform fertilization at the same time as planting seedlings.

The fertilizer application device is constructed as shown in FIGS. 1 to 3.

That is, a fertilizer feeding device 10a or 10b is provided at each of the left and right funnel-shaped bottoms of the fertilizer tank 9.
At the same time, a pair of left and right furrowers 12a and 12b are connected to the left and right pair of fertilizer feeding devices 10a and 10b through separate fertilizer supply pipes 11 at a location located in front of the machine body from the left seedling planting arm 5a. and a location located forward of the right seedling planting arm 5b of the machine body, respectively, and are attached to the ground float 8 via a groove plate 13. The left and right fertilizer feeding devices 10a,
10b, the seedling planting arm 5a of the feed-out roll drive shaft 14a or 14b in the longitudinal direction of each machine body.
Or swing links 15a, 15 attached to the rear end located above 5b so as to be integrally rotatable.
b. A first push-pull interlocking rod 16 is arranged along the lateral direction of the fuselage and interlocks the left and right swing links 15a and 15b; A second push/pull interlocking rod 17 connected to the swinging link 15a, and a swinging arm 18 connecting the lower end of the second push/pull interlocking rod 17 to the left seedling planting arm 5a, respectively. An interlocking mechanism 19 is configured between the left and right fertilizer feeding devices 10a, 10b and the left seedling planting arm 5a. That is, the left and right fertilizer dispensing devices 10a and 10b are driven by transmission from the left seedling planting arm 5a, and are driven in conjunction with the seedling planting movement.

To explain in more detail, the left and right fertilizer feeding devices 10
a and 10b are linked to the seedling planting movement of the seedling planting arms 5a and 5b, and take out a set amount of granular fertilizer from the fertilizer tank 9, and drop and supply it to the left furrower 12a or the right furrower 12b. . The left and right furrowers 12a and 12b are respectively connected to the left seedling planting arm 5a or the right seedling planting arm 5.
A groove is created near the side of the planned seedling planting location according to b, by pushing and expanding the groove formed by the groove cutting plate 13 for the purpose of machine advancement, and the fertilizer feeding device 10a or 1
Fertilizer from 0b is supplied by falling into the forming groove.

The fertilizer supply pipe 11 is provided with a lid portion 11a as shown in FIG. 4 for opening the fertilizer supply pipe 11 over its entire length to facilitate internal cleaning.

As shown in FIG. 2, the first push-pull interlocking rod 16 and the left and right swing links 15a, 15
A cover 20 covering the rear of the hood 4 is integrally molded with the bonnet 4. The lower end of the cover 20 is located at the same or almost the same level as the lower ends of the left and right swing links 15a, 15b, so that the left and right groovers 12a, 12b and their vicinity can be seen from the control position at the rear of the aircraft. The cover 20 is formed such that a space is secured below the cover 20, so that the visibility can be seen without any hindrance regardless of the cover 20, and the left and right swing links 1
By hiding 5a and 15b with a cover 20 to prevent their reciprocating operations from being seen, consideration is given to making it easier to accurately judge the fertilization status by visual observation from the operating position.
