Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tandem type vibrating roller having a front and a rear roller drum, and the drum itself is vibrated by the rotation of an eccentric pendulum provided in the drum of the bracket.

Many of the tandem type vibrating rollers in the subordinate structure have a power transmission part for applying driving force and vibration to both the front and rear roller drums, protruding outward from both sides or one side of a frame that supports the roller drums.

If the transmission mechanism is protruded outward from the frame in this way, if it comes into contact with a wall, along a curb, or directly under a utility pole, the transmission mechanism may collide with the wall or utility pole, causing damage to these structures. There is a problem in that it is not possible to press the rock directly under the frame as desired.Of course, if the transmission mechanism described above is installed only on one side of the frame, the side where the transmission mechanism is not protruding will be able to press the rock as desired. However, with this type of roller, if you move the machine back and forth in the same direction, you can compact one side edge of the road but not the opposite side edge.
In such a case, it is necessary to turn the aircraft 180 degrees and move it.

Therefore, with this type of roller, there is a problem in that it is absolutely necessary to perform an operation to rotate the machine body, and it is not possible to apply scale pressure in places where turning is impossible. Conventionally, in order to solve the above problems, the frame was made into an S-shape in plan, and the front and rear roller drums were constructed in a cantilevered form, with the sides of the front and rear drums being offset from each other with respect to both ends of the frame. What was supported by the above is being proposed.

(Special Publication No. 45-21145) This type of roller is located at the location mentioned above, and uses the greenery on the side of the drum, which does not have a support shaft, without changing the direction of the machine, to cover the greenery on both sides of the road. It is possible to apply pressure.

However, this type of roller has the problem that the support keys are all cantilevered and are subject to vibration, making the bearing portion unstable and easily damaged. The tandem type dowry roller according to the present invention takes into consideration the problems of the follower type roller as described above, and has an intersecting shape in which the front and rear roller drums are shifted laterally from each other. ``Each roller drum is supported on both sides by a support frame consisting of a pair of left and right side plates, and the support frames supporting the front and rear roller drums are not integral with each other but are divided into front and rear parts. By connecting the inner end of the Misaki roller drum support frame to both sides of the transmission located in the center of the fuselage in a cross-shaped manner via bran-proof rubber, the vibrations of the roller drum can be dissipated in the center of the fuselage. Next, the present invention will be described in detail with regard to the illustrated embodiment. FIGS. 1 and 2 are side views of a vibrating loaf according to the present invention,
FIG. 3 is a partially cutaway plan view.

The support frame 2 consisting of 22, the left and right side plates supporting both sides of the roller drum 3, and the support frame 2 consisting of 1 and 2 are formed separately. The outer weave of the front wheel support frame grass is fixed to both ends of the water tank 5 located at the front of the aircraft, and supports both ends of the front wheel roller drum spindle 6. Also, the outer edge of the rear wheel support frame & It is fixed to both ends of an L-shaped engine frame 8 fixed to the rear of the transmission 7 located in the center of the fuselage, and in this state supports both ends of the support shaft 9 of the rear roller drum 3. ing. The support frames 2 and 4 that pivotally support the respective roller drums 1 and 3 in this way
The outer end of one side plate of the rear wheel support frame W is arranged so that the arrangement positions of the front and rear roller drums in the longitudinal direction are shifted to the side. A rear wheel support frame side plate 4 fixed directly to the side end surface of the transmission 7, and an inner end of one side plate 2 of the front wheel support frame 2 fixed to the side end surface of the transmission 7, and a vibration-proof rubber IQ. , connected via turtle wings, the support frame 2

is provided. The driving force is transmitted to the front and rear roller drums 9 and 3 from the engine ridge 4 mounted on the engine frame groove to the input of the transmission 7 through the belt 1 and the drive output from the transmission 7. Axis sprocket thin fin, 9 Gun crab 2 to each roller drum 1

That is, as shown in the first diagram, both front and rear roller drums L3
The space created on one side of each roller drum by shifting the positions of the front wheels to the sides can also be used.

~ From the side plate 22 of the support frame of the drum electric, one end of the support shaft 6 of the drum is inserted, and from the side plate fin of the support frame of the rear roller drum 3, one end of the support shaft g of the drum is extended. ``The respective support shafts 6, the roller sprocket blades provided on the g shaft machine, the sprocket arm S at both ends of the drive output shaft of the transmission shaft 2, the wealth 82 and the chain turtle 8, respectively By connecting with the Tatami Ha 2, the two-wheeled roller drum 3 is rotationally driven.The transmission 7 is also provided with a vibrating output shaft pulley blade g in parallel with the drive output shaft sprocket gun. Along with "Front wheel roller drum turtle's low foot sprocket 1
7, was installed on the enemy aircraft on the spindle fin.

The pulley 28 and the puller iJ-tatami 9 are connected to the belt 2.
Connected from 1st and 28th row hoop
The spindle shaft equipped with the eccentric pendulum 22 rotates and gives vibration to the front wheel roller drum.
A protective cover provided on the outside to cover the power transmission part, 2 elbows are also side plates of the rear wheel support frame 4, and a protective cover for the power transmission part provided on the outside; 25 is the rear wheel support frame 4; The handle is attached to the rear end of the handle. The tandem-type vibrating roller according to the present invention has the structure as described above. The support frame 4 of the wheel roller drum 3 has one side plate 4, the inner end of which is fixed to the side of the transmission 7 in the center of the fuselage, and the other side plate 42, the inner end of which is connected laterally to the inner end of the side plate 4. The support frame 2 of the front roller drum 1, which is connected via a frame 12 and which generates vibration, is connected to the support frame 2 of the front roller drum 1, which generates vibrations, with both side plates 2, Both front and rear support frames 2,
4 are mutually divided, but are integrally formed in the center of the body. In this state, it is possible to prevent vibrations of the front wheel rollers from being transmitted to the rear wheel support frame 4.

In other words, even when the front wheel roller drum is vibrated, the vibration causes the gear shift rock in the center of the fuselage to vibrate, and the front wheel support frame 2 is connected to the gear shifter 7 via vibration isolating rubber. Therefore, the vibration of the front wheel support frame 2 is absorbed by the anti-vibration rubber and does not cause large vibrations in the heavy transmission, thus making it possible to significantly reduce the amplitude in the center of the aircraft. can. Of course, since the rear wheel support frame 4 and the front wheel support frame 2 are fixed to the transmission 7 through anti-vibration rubbers 10 and 11, the vibrations of the front wheel support frame 2 are not directly transmitted to them. Even if some vibration from the front wheel support frame 2 remains in the gear shifting section, the slight vibration in the center of the fuselage will not excite the rear rear wheel roller drum 3 itself, and as a result, the rear wheel support There is no need to separately apply anti-vibration measures to the handle 25 protruding from the rear end of the frame 4, making it extremely easy to operate the aircraft.Furthermore, the rear wheel support frame 4 only has one side plate 4. is fixed to the transmission 7, and the other side plate 42 is fixed to the transmission 7 and the front wheel support frame 2.
Although not connected to both sides, the side plates 4, 42 are connected to the horizontal frame 1.
2, the integrity with the front wheel support frame 2 via the transmission 7 is reliably maintained.

Furthermore, in order to connect the inner ends of the side slopes of both the front and rear support frames 2 and 4 via the transmission in the center of the body, a water tank 5 is placed at the front of the body and an engine 14 is placed at the rear of the body to maintain the front and rear balance. Furthermore, by providing the hanging fittings 13 on the horizontal frame 12 at the center of the fuselage, it has the advantage that it is possible to efficiently carry out lifting operations when transporting the fuselage.

Of course, in the vibrating roller according to the present invention, both ends of the support shafts of the front and rear roller drums 1 and 3 can be supported by both end plates of the support frames 2 and 4, respectively, so that the supporting shafts of the subordinate columns can be supported. Compared to a vibrating roller with a cantilevered shaft, the machine is safer and more robust, and has fewer failures.

Moreover, in the vibrating roller according to the present invention, since the two roller drums 1 and 3 at the front and rear sides are supported by the respective support frames 2 and 4 in a laterally shifted arrangement, each roller drum has a Although the power transmission part is on one side, the effective width of the fuselage is the sum of the roll widths of both roller drums 1 and 3), so it is possible to move forward and backward without changing the orientation of the aircraft. This has the advantage that both sides of the road can be covered with rock across the entire width, and work can be carried out efficiently.
