Description

[Detailed description of the invention] This invention, for example, fixes the chassis on which the engine is mounted in the middle of the transmission case, connects a steering handle to the upper end of the transmission case, and connects the chassis to the lower end of the transmission case via an axle. The present invention relates to a battery support device for a walking mobile agricultural machine that connects an agricultural machine such as a rotary work machine via a rear hitch and a hitch pin in a management machine, a tiller, etc. equipped with wheels. Conventionally, as shown in Japanese Utility Model Publication No. 37-3312, there has been a technique in which running wheels, an engine, a steering wheel, and a rear hitch are respectively disposed above, below, and in front of a transmission case.

However, since the above-mentioned conventional technology requires the battery to be attached to the middle part of the steering handle, the handle support load becomes large, making it difficult to simplify the handle changing structure, and also prevents the steering wheel from being in the correct position. In the reverse position, the center of gravity of the aircraft tends to change significantly, and
The battery is located away from the running wheels, which are the center of the machine's longitudinal rotation, and by locating the battery behind the running wheels, the longitudinal balance of the machine tends to become unstable, and space for installing agricultural equipment is secured. By supporting the battery at a high position, the left-right balance of the machine tends to become unstable.In addition, when the agricultural machine is lifted above the ground when turning the machine on a headland, the battery is tilted forward. There were problems such as easy movement up and down.

However, in the present invention, a pair of left and right running wheels are installed at the lower end of the transmission case, the engine is located at the front of the middle part of the transmission case, and the steering handle is moved back and forth at the upper end of the transmission case. The apparatus is characterized in that a mounting base is fixedly installed on the upper surface of the rear hitch provided at the rear side of the middle part of the transmission case, and a battery is attached to the rear hitch via the mounting base. .

Therefore, since the mounting base is fixed to the rear hitch, the rear hitch can be reinforced by the mounting base, making the rear hitch simple and robust, and a simple mounting base can be provided at the position closest to the running wheels. The battery can be easily installed with just a single button, and the conventional problem of the center of gravity of the aircraft changing greatly even when the steering handle is moved to the normal or reverse position can be eliminated. Moreover, the steering handle is lighter than before and can be easily moved. The steering handle support structure can be easily simplified, and the battery can be placed at a low position near the center of longitudinal rotation of the aircraft, resulting in better longitudinal and lateral balance of the aircraft than in the past. Even if the battery is tilted back and forth or left and right, the vertical movement of the battery can be reduced compared to before.
It can support the battery stably and safely.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a side view of the management machine, in which 1 is a chassis, 2 is an engine mounted on the chassis 1, 3 is a transmission case to which the rear end of the chassis 1 is integrally connected, and 4 is a transmission case for the chassis 1.

6 is the travel gear shift lever, 17 is the main clutch lever,
Reference numeral 18 indicates a side clutch lever, and 19 indicates a rear hitch, which is a machine-side hitch, which is fixed at the middle rear of the transmission case 3, and is used to change the direction of the steering handle 15 and the traveling gear shift lever 16 to the front or rear of the machine. It is configured so that it can be moved forward or backward to perform agricultural work.

As shown in FIG.
0 and 21 are fixed, seat plates 22, 22 and 23, 23 are respectively fixed to both ends of the bearing cylinders 20, 21 and the outside of the handle base 14, and the seat plates 22 and 23 are connected to the engagement protrusion 24 through the engagement protrusion 24. The seat plates 25, 25 to be crimped and locked are fixed to the base end of the steering handle 15, and the middle of the swing fulcrum bolt 26, which is passed through the base end of the handle 15 through the seat plates 25, 25, is fixed to the bearing tube 2.
0 or 21. A nut 27 is screwed onto the tip of the bolt 26, and the bolt 26 has an uneven surface 30 that supports the base end of the tightening lever 28 and comes into contact with the uneven surface 29 of the base end of the lever 28. The cam plate 31 is engaged and fixed to the handle 15, and each uneven surface 2 is moved by operating the lever 28.
9 and 30 are separated as shown in FIG. 2, and the seat plate 25 on the handle 15 side is crimped onto the seat plate 22 or 23 on the handle base 14 side, and while the handle 15 is fixedly supported on the handle base 14, the lever 28 is operated. The uneven surfaces 29 and 30 are joined together by a screw, and the mounting angle is adjusted by swinging the handle 15 up and down around the bolt 26.
The handle 1 via the bolt 26 to either
5 is attached, and the length of the handle 15 can be changed to two stages.The handle 15 can be shortened to make it easier to move around when working inside a greenhouse, or when a rotary work machine is attached. 5 is made long so that the worker's feet are wide.

As shown in FIGS. 3 and 4, a hitch bracket 32 is integrally connected to the rear hitch 19, and this tightening bolt 33 is installed in the middle of the rear side of the transmission case 3.
This is a mounting base on which a hitch bracket 32 is fixed through, a hitch pin 34 for connecting various agricultural machines is passed through the rear hitch 19, and a battery 35 is mounted. A bracket 36 is integrally fixed to the upper surfaces of the rear hitch 19 and the hitch bracket 32, and a battery 35 for starting the engine 2 is fixed to the upper surface of the bracket 36 with bolts 37 and a retaining plate 38. 35 is located approximately at the center in the longitudinal direction of the aircraft to maintain the left-right balance of the aircraft, and the engine 2 and battery 35 are placed in front and behind the transmission case 3, with the front of the aircraft slightly centered around the transmission case 3. It is constructed to be heavy and maintain this front-to-back balance.

The engine 2 is installed on the front side of the middle part of the transmission case 3, and the engine 2 is installed on the front side of the middle part of the transmission case 3.
In a device in which a steering handle 15 is connected to an upper end portion so as to be swingable back and forth, a mounting base 36 is fixedly mounted on the upper surface of a rear hitch 19 provided at the rear side of an intermediate portion of the mission case 3, and The battery 35 is attached to the rear hitch 19, and since the mounting base 36 is fixed to the rear hitch 19, the mounting base 36 is fixed to the rear hitch 19.
By this, the rear hitch 19 can be reinforced to make the rear hitch simple and robust, and the battery 35 can be easily installed by simply providing a simple mounting base 36 at the position closest to the running wheels 5. A steering handle 15 support structure that can eliminate the conventional problem in which the center of gravity of the aircraft largely changes even when the steering handle 15 is moved to the normal position or the reverse position, and also allows the steering handle 15 to be made lighter and more flexible than before. In addition, the battery 35 can be placed at a low position near the center of longitudinal rotation of the aircraft, allowing better longitudinal and lateral balance of the aircraft than in the past. Even if the battery 35 is tilted back and forth or left and right, the vertical movement of the battery 35 can be reduced compared to before, and the battery 35
This has practical effects such as being able to support the body stably and safely.
