Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a walking type mobile agricultural machine in which the middle part of a control handle formed in a U-shape in plan view is connected to a support frame extending from the machine body.

Conventionally, when attaching an operating lever such as a clutch to the middle part of a handle, a pair of left and right brackets is provided at the middle part of the handle, and the operating lever is pivotably supported on a shaft between the brackets. Ta.

In this way, with a structure in which the operating lever is swingably attached to the handle via a bracket,
The disadvantage was that it was expensive because a bracket had to be welded to the handle rod and a pivot shaft for attaching the lever had to be prepared.

The object of the present invention is to effectively utilize the original structure of an operating lever such as a clutch so that it can be mounted at low cost and with a simple structure.

The characteristic structure of this invention to achieve the above purpose is as follows:
In the above-mentioned walking type mobile agricultural machine, the control handle 4 is divided at the middle part in the left and right direction, and each of the divided handle parts is attached to a pair of left and right support frames extending from the machine body, and the divided ends of the divided handle parts are attached to a pair of left and right support frames extending from the machine body. are connected to each other in a state in which the handlebars are located inward from the support frame, and the operating levers are respectively fitted onto the handle rod portions between the pair of left and right support frames so as to be able to swing freely.

In other words, since the originally provided control handle is effectively used as the support shaft of the control lever, the control lever can be attached to the handle without using a bracket, resulting in cost reduction.

Moreover, the control handle is divided at the middle part in the left-right direction, and the control lever is configured to be fitted externally from the inner end of the fuselage, so that the control handle is integrally formed in a U-shape in plan view. The operating lever can be easily assembled compared to the case where the operating lever is fitted externally from the grip side.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a self-propelled body is equipped with a pair of left and right running wheels 1, 1, an engine 2, a spare seedling storage section 3, a control handle 4, etc., and a front float 5 and a Two rear floats 6, 6 arranged side by side on the left and right are attached, and four seedling planting arms 7 arranged side by side on the left and right are attached to the rear of the self-propelled aircraft...
...and a seedling planting section equipped with a seedling stand 8 to constitute a walk-behind rice transplanter capable of planting four rows.

As shown in FIGS. 1 and 2, the spare seedling storage section 3 is composed of one seedling shelf 3a and one seedling shelf 1, which store two pine-shaped spare seedlings in parallel in the lateral direction of the machine. Two seedling racks 3b and 3c for storing pine-shaped seedlings are vertically arranged side by side. The seedling racks 3a, 3b, and 3c are configured so that spare seedlings are placed on the seedling scooping board 9, respectively, and the seedling racks 3a, 3c are configured so that spare seedlings are placed on the seedling scooping board 9, respectively.
On the mounting surface of each of b and 3c, a plurality of protruding stoppers 10 are inserted and locked into the through holes 9a of the seedling scooping plate 9 so that the mounted seedlings do not slide even if the machine body is tilted forward or backward. They are placed side by side.

As shown in FIGS. 3 and 4, the operating handle 4 is constructed by connecting two bent pipe handle portions 4a, 4a with a pin 11 so as to be separable, thereby forming a U-shape in plan view. Then, the bracket 12 provided in the middle part is bolted to the two support frames 14, 14 extending from the planting case 13 forming the self-propelled aircraft body, while being tightened together with the operation box 15. It has been done.

An operating lever 17 is linked via a release wire 16 to a main clutch (not shown) provided in the transmission system from the engine 2 to the wheels 1 and the seedling planting section.
As shown in FIGS. 3 and 4, the control box 15 is swingably attached to the handle rod portion on the inside of the machine from the support frames 14, 14.
By swinging the clutch along the guide groove, the main clutch is disengaged when placed in the first operating position (ON).
Furthermore, the main clutch is engaged when it is in the second operating position (OFF).

A control mechanism that automatically raises and lowers the wheels 1 relative to the aircraft based on the detection result of the swing angle of the front float 5 relative to the aircraft so that the seedling planting depth remains approximately constant regardless of changes in the depth of the tiller. (not shown) and a seedling planting clutch (not shown) via a release wire 18. As shown in FIGS. In addition to being movably mounted, when the operation box 15 is moved to the first operating position (AUT) by swinging along the guide groove, the control mechanism is activated, the planting clutch is engaged, and the planting clutch is in the engaged position. When set to the 2 operation position (UP), the planting clutch is disengaged with the control mechanism giving priority to information from the float 5 and raising the aircraft above the ground.

Note that the levers attached to the operating handle 4 may be operated differently from the above-mentioned levers, and these will be simply referred to as operating levers 17 and 19.

The present invention can also be applied to various types of walking-type mobile agricultural machinery such as walking-type tillers and management machines.

Incidentally, although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
