Description

[Detailed Description of the Invention] The present invention includes a body frame that extends from the lower part of a traveling transmission case having an axle at the lower end to the front side of the body, an engine mounted on the front end side of the body frame, and an engine mounted on the front side of the body frame. The present invention relates to a walking type mobile agricultural machine in which a battery is mounted on the body frame and positioned between the upper part of the traveling transmission case.

Conventionally, in walking-type mobile agricultural machinery, the battery is surrounded by the engine and the traveling transmission case, so it is mounted so that it is not exposed to mud or water spray.
As disclosed in Japanese Utility Model Publication No. 56-13134, a fuselage frame extending from the lower part of the traveling transmission case to the front of the fuselage includes an engine mounted on the front end side of the frame, and an engine mounted on the front end of the frame, and It was mounted between the top and the top.

In conventional aircraft, the battery is located forward of the axle, and the moment due to the weight of the battery and the engine is large at the side where the aircraft moves forward and downward around the center of the axle. There were problems such as the amount of operating force required to maintain the aircraft in a horizontal position, making it difficult to maneuver.
Furthermore, the smaller the longitudinal distance between the battery and the engine axle, the more likely the traveling transmission case will fall backwards. The front and rear lengths of the aircraft became large, making them difficult to maneuver and requiring a large amount of space to store.

The purpose of the present invention is to make it possible to reduce the moment due to the engine weight and battery weight, and also to reduce the longitudinal length of the fuselage, even though the battery is mounted in the above-mentioned location.

This invention is based on the above-mentioned walking-type mobile agricultural machine.
When viewed from the side, the traveling transmission case is formed into a bent shape such that the upper part runs along the vertical direction of the aircraft and the lower part is inclined toward the front of the aircraft as the lower end approaches, and the axle is located below the battery. The function and effects are as follows.

That is, by forming the traveling transmission case into the bent shape, even if the axle is positioned below the battery and the longitudinal distance between the engine and battery axles is reduced, the upper part of the transmission case can be oriented vertically. It is made to stand close to the battery.

Therefore, the moment due to the engine weight and battery weight can be suppressed by reducing the longitudinal distance between the engine, the battery, and the axle, and the length of the machine body can be suppressed by bringing the upper part of the transmission case and the battery close to each other. It has become easier to operate both in terms of operations for maintaining the aircraft in a working attitude and in terms of steering operations, and it has also become advantageous in that it can be stored in a relatively narrow space.

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

A rotary tilling device 4 is connected to the rear of a traveling machine having a pair of left and right wheels 1, 1, an engine 2, a control handle 3, etc., and power is transmitted from the traveling machine to the tilling device 4 via a transmission case 5. This configuration constitutes a walking type tiller.

The engine 2 is equipped with a battery 6, which is mainly used as a driving power source for an engine starter device (not shown), mounted on the front end side of the fuselage frame 8 extending from the lower part of the tilling device/driving transmission case 7 toward the front of the fuselage. The engine 2 is surrounded by the engine 2 and the transmission case 7, and is placed between the engine 2 and the upper part of the transmission case 7, and is mounted on the fuselage frame 8 so as to be protected from mud and water spray.

The transmission case 7 is formed into an inverted dogleg shape in which the upper part is along the vertical direction of the aircraft body and the lower part is inclined so that the lower end thereof is located toward the front side of the aircraft body when viewed from the side. , the axle 9 attached to the lower end is positioned below the battery 6, so that the longitudinal distance between the engine 2 and the battery 6 and the axle 9, and the longitudinal length of the fuselage are minimized. Care has been taken to ensure that

The rotary tillage device 4 can be changed to various working devices such as a ridge erecting machine or a cultivator.
