Description

[Detailed description of the invention] Engines in mobile agricultural machinery are usually made movable to adjust belt tension, prevent swinging due to belt tension, and prevent engine vibrations from being transmitted to the machine base. Anti-vibration measures must be taken.

Therefore, in the past, as shown in Figure 7, the engine was fixed to the engine base, and the engine base was connected to the machine base via a steadying material consisting of a stopper and a rubber shaft, and then the engine base was adjustable with respect to the machine base. However, when adjusting the movement of the engine base, the steady rest became an obstacle to the movement, making it extremely difficult to adjust the movement.

Another attempt was made to fix the engine base to the machine frame using anti-vibration rubber and anti-vibration material as shown in Figure 8 as another engine mounting device, and to adjust the movement of the engine relative to the engine plate. Attaching the fixing bolts was extremely difficult and required a great deal of effort to assemble.

The object of the present invention is to provide an engine steady rest device that allows for extremely easy adjustment of engine movement, can be assembled with high efficiency, and that can reliably prevent the engine from shaking due to belt tension. In an engine mounting device in which an engine base is screwed onto a machine base via a vibration isolating material, a long hole is bored in a corner of the engine base substantially parallel to a transmission band to adjust the movement of the engine together with the engine base. An example of a plate-shaped steady rest attached to the machine base is superimposed on the upper surface of the mounting part of the engine base, and a round hole bored on one side of the plate-shaped steady rest is inserted into the engine base. Insert the base into the screw that attaches to the vibration isolator and screw it together, and drill a long hole in one side and a round hole in the other side of the corresponding part of the plate-shaped steady rest and the engine base. It is characterized by the fact that the two are screwed together.

The embodiment shown in the drawings will be described below. Reference numeral 1 denotes a machine such as a combine harvester consisting of a pipe 1a and a steel plate 1b, and a pulley 3 of an engine 2 distributes power to a traveling device, a threshing section, a reaping section, etc. The belt 4 that drives the device is suspended.

Reference numeral 5 denotes an engine base to which the engine 2 is mounted, and long holes 6a in the front-rear direction (direction of tension of the belt 4) are bored in each corner of the engine base 5. The upper and lower mounting brackets 7a and 7b are screwed onto the machine base 1 via a vibration isolating material 7 made of vibration isolating rubber 7c.

As shown in FIG. 6, the plate-shaped steady rest material 8 has a chevron-shaped portion in the middle, and a round hole 8a is also formed on the other side of the vibration isolating material 7 at a portion facing the bolt 9a on the second side. is long hole 8
A round hole 6b is bored in the engine base 5 directly below the elongated hole 8b, and a nut 1°a is fixed to the lower surface of the engine base 5.
...is drilled.

The lower end of a round bar 11, one end of which is welded to the chevron-shaped portion of the steady rest 8, is fixed to the machine base 1 via a vibration isolator 7', as shown in FIG. Loosely fit the elongated holes 6a of the engine base 5 and the round holes 8a of the steady rest material 8 into the bolts 9a of the vibration isolating material 7, and tighten with the nuts 12. Then, the bolt 10b inserted through the round hole 6b of the engine base 5 and the elongated hole 8b of the steady rest member 8 is screwed into the nut 10a and tightened, so that the steady rest member 8 and the engine base 5 are integrated. The setting position of the engine 2 can be adjusted by moving the engine base 5 in the direction of the slotted holes 6a and 8b while loosening the nut 12 and bolt 10b.
The position is determined by tightening the bolt 10b.

At this time, the steady rest member 8 is held at a fixed position by the round bar 11, and the round hole 8a is supported by the bolt 9a, so it does not move and only the engine base 5 moves.

The present invention provides an engine mounting device in which an engine base is screwed onto a machine base via a vibration isolating material as described above, and a long hole is bored in a corner of the engine base substantially parallel to the transmission band. one side of the plate-shaped steady rest attached to the machine base is superimposed on the upper surface of the mounting part of the engine base, and the plate-shaped steady rest The round hole drilled on one side is inserted into the screw that attaches the engine base to the vibration isolator and screwed together, and the corresponding part of the engine base and the other side of the plate-shaped steady rest are I drilled a long hole in the other and a round hole in the other and screwed them together, so
Mounting the engine, hooking the belt, and adjusting the tension of the belt are extremely easy.

In addition, since the plate-shaped steady resting material is superimposed on the top surface of the engine base, it can be installed at the appropriate position at the same time as or after the engine is set, and one side of the engine base has a vibration isolating material that is integrated with the machine base. The plate-shaped steady rest is securely tightened and fixed, and on the other hand, it is fixed to the non-movable plate-shaped steady rest with screws, so even if the belt tension changes, the mounting position of the engine and engine base will not change. can be prevented.

Furthermore, even if one of the screws becomes loose, the steady rest function can be maintained.
