Description

[Detailed description of the invention] The purpose of this invention is to significantly suppress vibrations of the machine due to vibration transmission from the engine. The engine was simply mounted and fixed on the engine mounting frame that was fixed and extended backwards from the rear, but in this proposal, in addition to this, the engine and transmission case, or a fixed wall such as a handle frame fixed to this, will be added. A vibration suppressor is mounted between the vibration suppressor and the fixed position of the vibration suppressor on the engine side or the transmission case side can be changed. In this case, the impedance of the machine is changed and the vibration is reduced by making the engine mounting frame and the vibration suppressor support each other.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a side view of the binder, and reference numeral 1 denotes a transmission case. A pair of left and right drive wheels 2 are pivotally supported at the bottom of the case, and a working device support frame 3 is fixed to the front of the case.
An engine mounting frame 4 is fixedly extended rearward from the lower part of the back surface.

The working device support frame 3 supports a planted culm lifting device 5, a reaping device 6, a horizontal conveyance device 7, and a bundle release device 8.

Further, a control handle 9 is fixedly extended rearward from both sides of the upper part of the working device support frame 3.

The engine 11 is mounted and fixed on the engine mounting frame 4 with bolts 10, and as shown in FIG.
As a result, the vibration direction 15 is directed toward the wheel grounding point 16 or the axle shaft 17 shown in the solid line diagram, and as a result, the main machine consisting of the transmission case 1, working equipment, etc. The vibrations transmitted to the machine 18 are well absorbed by the ground, and the vibrations of the machine 18 are reduced.

A vibration suppression frame 19 is attached to bolts 20 over the upper part of the crank case 11a of the engine 11 and the upper part of the transmission case 1.
As a result, compared to the case where the engine 11 is cantilevered by the mounting frame 4, the engine 11 is supported on both sides by the mounting frame 4 and the vibration suppression frame 19, Since the impedance of the machine 18 changes, by designing in advance so that this impedance has an appropriate value, it is possible to reduce vibrations of the machine 18 due to transmission of vibrations from the engine 11.

As shown in FIG.
A, 25b and one location 25c of the handle 90 base mounting frame 9a can be selectively fixed, so that the machine 18 can be selectively fixed to any one of the locations 25c and 25c of the handle 90 base mounting frame 9a. This allows it to be used with less vibration.

In this case, changes in working conditions include, for example, the engine rotation speed when changing the harvested and tied variety such as rice, wheat, or rush.
Possible changes include changing the running speed of the machine or the operating speed of the work equipment.

In addition, the belt 23 wrapped around the boots I721 and 22 which are pivotally supported on each side of the engine 11 and the transmission case is covered with a belt cover 24, and the belt cover 24 is fixed to the engine 11 and the transmission case 1. be.

As described in detail above, the present invention has a vibration suppressor mounted between the engine supported on the engine mounting frame fixedly extended from the mission case and the transmission case or something fixed to the same. Since the fixed position of the vibration suppressor on the engine side or the transmission case side can be changed, it is possible to significantly suppress the vibration of this machine due to vibration transmission from the engine, increasing the durability of the binder as a whole. can be increased.

Moreover, since the fixed position of the vibration suppressor can be changed, it can be fixed in accordance with changes in work conditions such as changes in engine speed, machine running speed, or operating speed of the work equipment when changing the reaping binding type Q. Depending on the location, the machine can be used with the least amount of vibration.

Moreover, since the structure for this purpose is as simple as adding a vibration suppressor, it can be implemented at extremely low cost.

Claims (1)

[Scope of utility model registration request] A transmission case 1 equipped with a pair of left and right drive wheels 2 at the bottom also has an engine mounting frame 4 fixedly extended backwards, and an engine 11 placed and fixed on the engine mounting frame 4 and the transmission case 1 or fixedly fixed thereto. The vibration suppressor 19 is mounted between the fixed positions 25a, 25b, and the vibration suppressor 19 on the engine side or transmission case side.
