Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a transmission device for a management machine, and is used for a device for compacting lawns, soil, etc.

Conventional Technology and Problems to be Solved by the Invention Normally, a control machine's suppression work device supports a transmission shaft via both left and right bearings at the lower end of a transmission case that houses a transmission mechanism such as a transmission chain or gears. This is a type of structure in which a pair of pressure rollers on the left and right are supported by this transmission shaft, but as a simple working device, it requires a large number of parts such as sprockets and transmission shafts, and is heavy and may be expensive. Therefore, it is an object of the present invention to reduce the number of constituent members and reduce the weight to provide a low-cost compaction work device.

Means for Solving the Problems This invention provides a transverse power transmission shaft 2 having a V-pulley 1.
At the lower end of the transmission case 3 which supports and is installed inside, there are left and right upper bearing parts 4, 4 which are integrated with the transmission case 3 divided into upper and lower parts, and left and right upper bearing parts 4, 4 which are separate from these bearing parts 4.4. A bearing body 6 having lower bearing parts 5, 5 is provided, and these upper and lower both wheel bearing parts 4°4.5.5 are provided with the left and right bearing parts 4,
5, 4.5, and the V-groove portion 7 receives belt transmission from the V-pulley l; both left and right shaft portions 8, 8 supported by the bearing portions 4, 4, 5.5; Squeezing roller parts 9, 9 protrude from the shaft part 8.8 in both left and right directions, respectively.
The transmission device of the management machine is composed of a hollow integral rotating body of 10 tM.

Effect of the Invention The V-groove portion 7 of the rotating body 10, which is belt-transmitted from the power transmission shaft 2 via the V pulley 1, is connected to the left and right pressure roller portions 9 of the rotating body 10 via both shaft portions 8, 8 of the rotating body 10 Transmitted to 9.

Effects of the Invention As described above, since the hollow integral rotary body 10 serves as both a V-pulley and a transmission shaft, the number of members is reduced and the weight is reduced, so that the crushing work device can be made lightweight and inexpensive.

Embodiment: When rotated, the gear case 12 supports the vertical input shaft 11 transmitted from the prime mover side and has its left side open.
The right side of the upper end cylindrical portion is opened to the open surface of the transmission case 3, which houses the vertical belt transmission mechanism, and is coupled to the open surface of the transmission case 3.

A small-diameter bevel gear 13 is fixed to the lower end of the input shaft 11. Below the bevel gear 13, the left end is connected to the left wall of the transmission case 3, and the right end is connected to the gear case 12. A transmission shaft 2 supported on the right side wall is provided, and a large diameter bevel gear 14 that meshes with the small diameter bevel gear 13 is rotatably provided at the right end of the transmission shaft 2. On the left side of the bevel gear 14 on the top 2, the bevel gear 14
A clutch 15 is provided that can connect and disconnect transmission of power from the transmission shaft 2 to the transmission shaft 2. Note that 16 is a partition wall that partitions the two cases 2 and 12, and 17
is a sealing member.

On the left side of the transmission shaft 2, there is a V of the belt transmission mechanism.
The pulley 1 is fixed to the lower end of the transmission case 3, and left and right upper bearing parts 4, 4 are integral with the transmission case 3 divided into upper and lower parts, and these bearing parts 4, 4 are separate parts. A bearing body 6 having left and right lower bearing portions 5, 5 is provided, and a flange portion 18 provided on the lower surface of the upper bearing portion 4゜4 and a flange provided on the upper surface of the bearing body 6. The part 18 is bolted.

Also, for both the upper and lower bearing parts 4, 4, 5, 5.

The V groove part 7 is located between the left and right bearing parts 4, 5, 4.5 and transmits power from the pulley 1 by the V belt 19, and the bearing member 20 is connected to the bearing parts 4, 4, 5, 5. Both left and right shaft portions 8, 8 are supported by.

A hollow integral rotary body 10 is provided, which is made up of pressure roller parts 9, 9 that protrude outward from both shaft parts 8, 8, respectively. Lid bodies 21, 21 are respectively provided to cover the.

Next, the effect will be explained. The input shaft 11 that is transmitted from the prime mover side includes bevel gears 13, 14, a clutch 15, a transmission shaft 2, a V pulley 1, a belt gear 9, and a V groove 7.
The power is transmitted to the rotating body 10 via.
