Description

1 9 Π S 7 7

This compaction is directed to the hydraulic drive and leveling vibrator, and ae is intended to be excavated in a non-excavator.

Soil compaction shakers are known in the art and can be used, for example, in excavators or other machines. Known vibrators are not prepared in such a way that they enclose the vibrator device information, e.g. single or ueeam pia, and are intended to be carried by an excavator or, for example, a dredger, not to be placed in a pit.

The troughs can be hydraulically or 1.1 diesel or diesel or benzene driven. However, there are disadvantages of diesel or benign fuel, which already start at ground level and become dirty according to the depth of the underground filling, namely the fact that these machines, which are most often used, do not work. , which poses a danger to the health of the user, and does not state that they are heavy and must not be placed in a pit or raised in a pit with a hoist or excavator.

These dampers connect the shoulder blade to the ground plate plate and are designed so that their axes of asymmetry are transverse to the excavator. In this case, the weakest direction of the dampers when they are loaded is the same direction as where the machine forces become greatest, i. the longitudinal direction of the excavator, which is disadvantageous. The general rule is that the dampers must be installed in proportion to the selected tread unit. In the Canadian case, it is a tortoiseshell with no directed centrifugal force, i. The tary unit has the same centrifugal force around the entire e-Kesko rotation as it rotates left or right. It would be more advantageous if the centrifugal force were higher in one direction (working direction) and lower in the other direction (directly in the opposite direction).

EP-A-0 220 373 discloses an excavator-controlled earth vibrator, the base plate 16 of which is acted upon by directional variations. The base plate is connected to the yoke 65 with vibration dampers, which are also mounted on their axes of symmetry in the transverse direction of the machine.

The object of the present invention is to provide a soil compaction and leveling vibrator which does not have the above-mentioned drawbacks, thus proposing a soil compaction vibrator equipped with vibration dampers installed that the strongest direction of the dampers is the same as the strongest direction of the excavator. This is achieved in such a way that the vibration dampers are mounted in a known manner in the corner between the four bases and the vibrator plate, whereby according to the invention the axes of symmetry of the vibrator dampers are mounted in the longitudinal direction of the excavator and the vibrator unit. According to the invention, the tumbler further comprises two generally directed end plates at opposite ends of the tumbler plate, the function of which is to enable the leveling of the earth masses, etc. outside the tumbler.

In order for the soil compaction and leveling vibrator to work best with the installation according to the invention, the vibrator unit must have two eccentrics, which in a manner known per se are 3 9057? on the same line with respect to each other, this line being inclined according to the invention with respect to the longitudinal and transverse direction of the vibrating plate (mounted in the direction of the diaphragm of the vibrating plate).

* These two eccentrics are most preferably mounted in an elongate housing. This results in a partly limited size for the soil compaction plate, so that its desired high pressure per unit area can be maintained, in part as a good protection for the vibrator unit with its associated hoses and connections. In addition, thanks to the aforementioned upward-facing end plates, it is achieved that loose excavation masses can be received at the ends and the excavation masses themselves can be leveled on the tortoiseshell by using it as a tool before compaction begins.

The upper side with its damper brackets is extended downwards, and its lower ends act as stop surfaces which strike the base plate and reduce the load on the dampers to a suitable level.

In more detail, according to the invention, a longitudinal upper part of a soil compaction and leveling vibrator, shaped in the shape of a yoke with a bracket supporting, e.g. , with two eccentrics and a directed centrifugal force, the vibration dampers, for example rubber, being placed between the upper part and the lower part. The turret is characterized in that the end plates form a counterpart to the ground masses when leveling the seals and that the agitator unit is placed in the agitator in the direction of the diagonal

The disadvantage of the well-known vibrators is that in women the most sensitive part of the damage, namely the couplings to the clutches to the hydraulic motor, are on the far or right side of the normal direction of travel, so that the edges of the trench and mini obstacles can easily become obstructive. damage. In the present case, on the other hand, the motor is turned in such a way that, although its connections are easily accessible, they are well protected behind the end plates and at the top in a freely free direction.

The invention will now be described in more detail with reference to the accompanying drawings, in which: Fig. 1 The same reference numerals have been used in the various figures where this has been possible.

Correspondingly, the installation of dampers and the eccentric unit of the vibrating unit, as well as the latter eccentric units, is of great importance. The vibrating effect must be directed in a vertical direction, so that the strongest vibrating effect is obtained downwards and correspondingly upwards. To achieve this result, the eccentric unit can be best equipped with two synchronously rotating eccentric wheels in such a way that they are eccentricized both upwardly and outwardly in their respective positions, so that their joint forces do not cause the greatest force. one another.

As mentioned above, the road leveling and leveling vibrator according to the invention is illustrated in a side view in Fig. 3a, a top view in Fig. 2 and an end view in Fig. 3.

In the illustrative drawing 1, the upper part with its fasteners is shown. the arm of the excavator and the downwardly directed support plates 1 ', 2 depicts four vibration dampers, 3 is the base plate, 4 is at the top against the base plate of the pyreit, , 6 is a directional direction with two eccentric and deflected chain exhaust valves, 7 is a hydraulic motor, 8 is a pressure, flow and rear valve i 1iyk8 ikkd, 9 further illustrates a , and 10 pictures of hydraulic hoses,

The structure illustrated in Figures 1-3 provides significant advantages. According to it, by using a tiny-tiny sink 6 with a directed keak-ejection force, without compromising its properties in any way, it can be reduced to the base plate at any angle to the shock absorbers, in which case It is well protected, regardless of which four sides of the machine are exposed to stubble, and that the hoses coming from the engine to the pressure, flow and rear valves 8 are well protected below the top with the gaskets on the other side of the stator. Joe's hoses must be connected from the main drive side, turned on the shaker plate half a turn. The purpose of the pressure, flow and non-return valve in the pressure section is to protect the connection to machines with a high connection pressure, when the flow is prevented from flowing into the turret so that it obtains the required oil volume regardless of the excavator's power. A stator system with large rotating ground must have a non-return valve i 1 i to prevent recoilings when the stator is switched off.

It does not matter which side is forward or backward of the excavator. The installation in the direction of the diagonal continues to have a favorable stiffening effect on the base plate. If the power of the IC is to be slurried, an additional motor can be simply installed in the direction of the stage unit, in which the same protective space is free. This exemplary engine is labeled 9:11.

Merk i ttåvåst. It can be thought of the opening of the shock absorbers at an angle of 90 ° to the existing ones, and of the fasteners, such as the end plates, which further adds to the leveling properties when it comes to filling masses. Such a tarot can be installed on machines with significant turning forces.

Furthermore, the attachable and detachable side plate 1 (Fig. 2) on one or both sides of the tarper unit can be fastened to the ends of the end plates and form folds. eu-ee excavator, and can thus be calculated to be exposed to significant turning forces.

It should be emphasized that the compacted soil compaction and leveling hopper does not necessarily need to be used in conjunction with the excavator deck, but any equipment capable of lifting the vibrator and being able to feed it with hydraulic pressure and flow can be used.

A variation of the vibrator can be made by installing a vertically downward pipe (not shown) below the base plate 3, whereby the movement of the vibrator can be used to make holes in the ground.
