Abstract

PURPOSE:To make a controller light and microminiature size. CONSTITUTION:In a rotary cover 1 supporting a rotary shaft 6 equipped with a working tine 7 for tillage, etc., through bearings in the right and left transverse direction, covering the upper part and the left and right side parts of the rotary working tine and having a semicylindrical shape when viewed from the side direction, the rotary cover 1 is designed so as to be separable in the right and left directions at a suitable position of the right and left intermediate part. On the outer surface of the side wall opposite to the separable part of one side of this separable rotary cover, at least one side member 1f of a transmission case is formed monolithically with the rotary cover 1 so that the upper end side may project from the outer peripheral surface of the rotary cover 1. A through hole 5 for a drive shaft 5 is made in the projecting transmission case member 1f and a motor 8 is suitably attached to the transmission case member 1f so as to be arranged on the upper surface of the rotary cover. This rotary cover characterized as above is used for the controllers of microminiature size.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a rotary cover in a microminiature management machine.

[0002]

2. Description of the Related Art Heretofore, there have been known micro-miniature control machines as disclosed in Japanese Patent Laid-Open No. 59-153669 and Japanese Utility Model Laid-Open No. 59-178019. These rotary covers are transmitted to the left and right intermediate portions. The former is a center-drive type in which a case is arranged, and the latter is a side-drive type, but its transmission case is a dedicated transmission case different from the rotary cover. Was there.

[0003]

In the prior art, the transmission case and the rotary cover are composed of separate members and the structure is complicated, so that the rotary cover is not suitable for a lightweight and ultra-small management machine, and the rotary cover is high in cost. It was.

[0004]

The present invention takes the following technical means in order to solve the above-mentioned problems. That is, the rotary shaft 6 is supported in the lateral direction, the work pawl 7 for plowing or the like is attached to the rotary shaft 6, and the rotary work pawl is covered from the upper and left and right side views. In a rotary cover 1 formed in a semi-cylindrical shape, the rotary cover 1 is divided into right and left parts at right and left intermediate places so as to be separable.
At least one side member 1f of the transmission case is formed integrally with the rotary cover 1 on the outer surface of the side wall on the side opposite to the split side of the rotary cover on the one side, and the upper tip side thereof protrudes from the outer peripheral surface of the rotary cover 1. With such a construction, the projecting transmission case member 1f is provided with the drive shaft insertion hole 5, and the prime mover 8 disposed on the upper surface of the rotary cover is appropriately attached to the transmission case member 1f. Used as a rotary cover for a small management machine.

[0005]

[Embodiment] 1 is a rotary cover which also serves as a machine frame, and has a cover portion 1a having a semicylindrical side view and left and right side cover portions 1a.
b and a battery mounting base 1c for mounting the battery-2 whose rear end side is extended rearward as in the embodiment example, and further a handle mounting bracket 1d and a shaft support projection 1e for mounting a support shaft of the wheel 3 on the front side. Is provided. The rotary cover 1 is vertically separable at the left and right intermediate portions. (A) is the division plane. A transmission case member 1f for transmitting and rotating the rotary shaft in the case 1 is integrally formed on the outer surface of the right side cover-1b of the rotary cover 1. That is, in the embodiment, as disclosed in FIG. 3, a half case type case member 1f is formed in which the transmission case is completed when the cover 4 is attached to the outer surface of the rotary cover. In the embodiment in this case, the structure is formed by molding with resin or aluminum alloy. Reference numeral 5 denotes a drive shaft insertion hole formed on the protruding end side of the transmission case member 1f.

A rotary shaft 6 is rotatably supported between the side cases 1b and 1b of the rotary cover 1, and a work claw 7 is attached to the bearing. Reference numeral 8 denotes a motor as a prime mover, which is integrally assembled with a motor main body 8a, and a drive shaft protruding from an outer end surface of the reducer 8b is a drive shaft of the transmission case member 1f. The speed reducer end face is projected from the insertion hole 5 and is joined and fixed to the mating face of the transmission case member 1f. Then, a chain transmission, or an appropriate reduction gear mechanism, is provided in the case member 1f between the drive shaft on the reduction gear side and the rotary shaft, and the motor 8 is closed by the lid 4 to seal it. The rotary shaft 6 is adapted to rotate. Of course, in the case of this embodiment, the motor 8 has a wiring structure capable of rotating in the forward and reverse directions. Reference numeral 9 denotes a steering handle, the base side of which is fastened to the bracket 1d.

As described above, when the rotary cover 1 is divided into the left and right parts, the peripheral surface of the case 10a on one side and the peripheral surface of the case 10b on the other side are arranged as shown in FIGS. The entire width of the case can be adjusted in the left-right direction by superposing them and is fixed with the set bolt 11. At the same time, as shown in the figure, the rotary shaft is divided into left and right types, and auxiliary work is performed between both shafts. The working width can be increased by connecting with the tubular shaft 16 with the claw 17. In this embodiment, the rotary cover is made of sheet metal, and the handle is fixed to the upper surface of the case 1.

In order to rotate the rotary shaft 6 in the normal or reverse direction by rotating the motor 8 in the normal direction or in the reverse direction, one of the left and right steering rods of the steering handle 9 is the forward rotation switch SW1 and the other is the reverse rotation switch S.
The motor 8 does not rotate only by providing W2 and turning on the main switch SW0, and the motor 8 is transmitted in the direction of rotation only when the forward rotation switch SW1 or the reverse rotation switch SW2 is turned on. Configure an electric circuit. A panel 18 to which switches and indicators are attached is provided at the center of the left and right of the steering wheel 9, and 19 is a pilot lamp,
In the illustrated example, a fuel gauge 20 having a battery 20 is incorporated.

Explaining the operation of the above example, since the transmission case member 1f for transmitting the power from the motor 8 to the rotary shaft 6 is integrally formed on the outer surface of the rotary cover 1 to reduce the weight and size, The output of a small motor 8 is sufficient for rotary shaft 6
It can be driven and rotated, and an ultra-small management machine can be realized. In the management work, when the main switch SW0 is set to "ON" and the forward rotation switch SW1 is set to "ON" in the case of forward work, the motor 8 rotates in the forward direction and the rotary shaft 6 rotates in the forward direction to work claws. At 7, the farm scene is cultivated and the vehicle runs.
In the case of reverse work, it is advisable to set the reverse rotation switch SW2 to "ON". During such management work, when the bottom surface of the battery mounting base 1c is brought into contact with a field scene to perform forward work, the cultivated surface can be leveled.

[0010]

According to the present invention, since the transmission case member 1f for transmitting the power from the prime mover side to the rotary shaft 6 is integrally formed on the outer surface of the rotary cover 1, the weight and the size are reduced. The rotary shaft 6 can be sufficiently rotated by the output of the prime mover, and an ultra-small management machine can be realized.
