Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention includes a driving unit in the front, a seedling planting device in the rear, and a transmission case in the driving unit and a seedling planting device in the rear. The present invention relates to a walking type rice transplanter that is integrally connected to a planting transmission case of the device via a pipe frame containing a transmission mechanism to form a traveling body, and is equipped with a fertilization device.

[Conventional technology]

Conventionally, in a walk-behind rice transplanter having the above configuration, as disclosed in, for example, Japanese Utility Model Application No. 63-138009,
The fertilization device was supported by a bracket extending from the pipe frame, and the transmission case and planting transmission case were connected and fixed only by the pipe frame.

[Problem to be solved by the invention]

However, in the conventional structure described above, the total weight of the seedling planting device and the total weight of the fertilization device must be supported only by the pipe frame, and the pipe frame and the connection point between the pipe frame and the transmission case are made of highly rigid materials. However, the structure has to be made thicker and a reinforcing member is added, which leads to a complicated structure.

The present invention aims to eliminate the above-mentioned disadvantages through rational structural improvements.

[Means to solve the problem]

A characteristic configuration of the present invention is that in the walk-behind rice transplanter described at the beginning, the upper part of the transmission case and the upper part of the planting transmission case are connected and fixed via a frame member, and the fertilization device is attached to the frame member. The point is that a support part is provided for use.

[For production]

By connecting the upper parts of the mission case and the planted transmission case via the frame member, a frame structure having a rectangular frame shape in side view is formed by each of the two cases, the pipe frame, and the frame member. , the entire fuselage becomes highly rigid. In addition, this frame member
Since the structure supports the fertilizing device, the weight burden can be distributed, and the frame member and the fertilizing device mounting portion can be used in common.

〔Effect of the invention〕

As a result, through rational structural improvements, it is possible to construct a strong framework structure, and it is also possible to form the nokuib frame with a thinner wall than before, which simplifies the structure and makes the aircraft more flexible. It has become lighter. Moreover,
There is no need to connect long fertilizer equipment support brackets from the large pipe frame that is the main frame material.
It also has the advantage of reducing processing time.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 4 shows a walking rice transplanter according to the present invention. This rice transplanter has an engine (3) mounted on a frame (2) connected to the front of a mission case (1).
), and also connects the planting transmission case (6) in the seedling planting device (5) installed at the rear of the fuselage via the pipe frame (4) fixedly extended from the rear of the mission case (1). A pair of left and right running wheels are integrally connected to form the aircraft body, and are connected to the left and right sides of the mission case (1) via wheel transmission cases (7) that are swingably pivoted around a horizontal axis (Pl). The wheels (8), (8) are supported on the machine body so as to be able to swing up and down, and the fertilizer application device (9) is arranged between the wheels (8), (8). In addition, a ground flow (10) is connected to the lower part of the fuselage so that it can swing vertically around the rear fulcrum (P2) and roll left and right around the longitudinal axis (P).

The seedling planting device (5) is a seedling loading device that reciprocates left and right at a constant stroke with respect to a planting transmission case (6) that is powered via a transmission shaft (not shown) in a pipe frame (4). It consists of a platform (11), a planting claw (12) that cuts out seedlings one by one from the lower end of the seedling platform (11) and plants them on the field surface, and the planting claw (12) is connected to a planting transmission case (6). It is attached to the bottom of the screw shaft (13) for horizontal movement of the seedling stand (11).
is provided on the upper part of the planting transmission case (6) so as not to obstruct the operation of the planting claw (12). In this way, the seedling planting device (
The drive system of 5) is disposed on the front side of the machine body of the seedling platform (11) to correct the front-rear weight balance of the machine body, which is piled up when seedlings are placed thereon.

In addition, a control handle (14) extends rearward and upward from the planting transmission case (6), and an operating section (16) such as a main clutch lever (15) is provided at the left and right intermediate portions. . Then, as shown in Fig. 5, the main clutch lever (1
5), when operating the engine starting recoil starter grip operation tool (17) and choke knob (
18) to prevent the engine (3) from being accidentally started with the main clutch lever (15) in the engaged state.

The fertilization device (9) is a fertilizer (19) for storing fertilizer.
, a feeding mechanism (20) that feeds out a predetermined amount of fertilizer from the lower end of the hopper (19), and a downflow pipe (22) that guides the fed fertilizer down into a groove formed on the mud surface by a groove cutting device (21). ), etc., and the feeding mechanism (20)
The fertilizer is delivered by rotationally driving a delivery roll (23) having a concave portion for entering the fertilizer in its outer circumference.

Then, the upper part of the transmission case (1) and the upper part of the planting transmission case (6) are connected and fixed via a frame member (24), and the fertilization device (9) is attached to the frame member (24). A support part (25) is provided. More specifically, as shown in FIGS. 1 and 2, a bracket (26) fixed to the frame member (24) and an arm (27) bolted to the bracket (26) are connected to the support portion ( The fertilizer application device (9) is supported by support shafts (28), (28) extending from both ends of the arm (27). Moreover, as shown in FIG. 3, the drive shaft (2
9) are supported by boss portions at both ends of an arm (31) bolted to a bracket (30) fixedly extended from the frame member (24). The rotation of the drive shaft (29) is driven by a crank mechanism (32) for driving the planting claw (12).
It is configured so that it is carried out in conjunction with.

As described above, by connecting the upper parts of the mission case (1) and the planting transmission case (6) with the frame member (24), a strong frame body having a rectangular frame shape in side view is constructed, and the pipe frame ( In addition to simplifying the structure of step 4), the structure is effectively used to support the fertilizer application device (9), reducing the processing required for the large pipe frame (4) that is the main frame body, and improving processing efficiency. This reduces the effort involved.
