Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a loading earth and sand holding device for pressing the earth and sand loaded on a carrier to shape it into an appropriate packing form.

<Conventional technology> Generally, in constructions that generate a large amount of excavated earth and sand, and in gravel collection sites, etc., a hopper is installed.The carrier bed is located below the hopper, and the hopper is opened to load a prescribed amount of earth Then, the transport preparatory work is completed by covering the sheet with the scattering prevention sheet.

<Problems to be solved by the device> In this series of work, the piles of earth and sand transferred to the loading platform make the seating operation unstable and troublesome, and the volume is bulky and the packaging looks high. In some cases, the loading weight was small, and there were cases where earth and sand spilled out from the gaps between the sheets.

Therefore, after the loading of the sand and sand is finished, the load and sand may be flattened according to the loading platform, but this shaping work is done by hand using a shovel or shovel such as a shovel car. For,
This work itself was troublesome and time-consuming.

Therefore, this invention shortens the time from loading to shipping by automating this kind of shaping operation, saves labor, and provides a loading earth and sand pressing device that can load an appropriate weight of earth and sand in a low packing style. The purpose is to provide.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a rectangular frame-shaped frame formed in a length, a width, and a height of loaded earth and sand according to the dimensions of a carrier of a carrier. A holding plate that can be raised and lowered via a pantograph mechanism arranged on the lower surface of the top of the frame, and a cylinder that expands and contracts the pantograph mechanism.

<Operation> According to the above configuration, after loading the earth and sand, the carrier is moved inside the frame to make the loading platform face the lower part of the holding plate, and when the device is driven, the holding plate descends and piles up. As a result of pressing the top of the soil in the state, the loaded soil is shaped into a trapezoidal packing and is consolidated.

<< Embodiment >> An embodiment of the present invention will be described below in detail with reference to the drawings.

1 to 3 show a loading earth and sand pressing device according to the present invention, in which 1 is a frame made by assembling steel materials in a rectangular shape, and is a vehicle width of a carrier D and a length of a bed D1 thereof. The inside dimension is set according to the height dimension and the height dimension of the earth and sand S loaded on this, and both sides in the length direction are openings for the entrance of the transport vehicle D.

Also, both sides of the frame 1 are reinforced steel members 1a of truss group.
Is integrated, and a trap 1b, a handrail 1c, etc. for inspection etc. are assembled on one side.

A pair of supporting steel materials 2 are fixedly arranged on the top surface of the frame 1 in parallel with the longitudinal direction thereof, and cross arms 3 and 4 constituting a pantograph mechanism are expandably arranged at the lower part thereof. The lower portions of the arms 3 and 4 are connected to the holding plate 5.

Each of the cross arms 3 and 4 has its center connected via a pin 6 in an X shape.

The upper end of one cross arm 3 is rotatably supported by a bracket 7 provided on one end side of each steel material 2 via a support shaft 3a, and the lower side thereof is a slide guide provided on one upper end of the holding plate 5. 8 is slidably connected to the guide roller 8 via a guide roller 9.

The other side cross arm 4 has a structure which is upside down from the above.

That is, the slide guide 10 is provided on the lower part of the other end of each steel material 2.
A shaft 11 provided on the upper portion of the other cross arm 4 is slidably supported on the guide 10 via a guide roller 12, and the lower side is supported by a bracket 13 provided on the other end side of the holding plate 5. It is rotatably connected via a support shaft 4a.

The shaft 11 is connected to a hydraulic cylinder 15.

This hydraulic cylinder 15 has a fixed plate 16 provided horizontally between the steel materials 2.
Is pivotally supported by the lower surface of the shaft, and the tip of the plunger 15a is connected to the shaft 11 at right angles.

When the plunger 15a is retracted into the hydraulic cylinder 15, the crossbars 3 and 4 intersect in a nearly horizontal state, and the pressing plate 5
Waits in the ascending position as shown by the solid line. In this standby state, the carrier D can enter the frame 1 with a pile of earth and sand.

When the plunger 16a projects, the cross arms 3, 4
Are tilted so that they are raised from each other in a state in which they are close to horizontal, and as a result, the holding plate 5 moves down while maintaining the horizontal state, and the guide rollers 9 and 12 abut at the end portions of the slide guides 8 and 10 to operate It is regulated and eventually stops at the imaginary line position in the figure.

Therefore, the piled soil S is pressed by the pressing plate 5, is consolidated, and is shaped into a trapezoid, so that the subsequent sheet hanging operation can be easily performed.

It should be noted that the button operation for raising and lowering may be performed by an operator other than the driver, or a remote control button is provided near the driver's seat of the carrier D and the driver performs the button operation by himself / herself. You may do it. Further, the shaping operation may be completed by one operation, or the operation may be divided into several operations. <Effect of the Invention> As described in detail in the above embodiments, In the device for loading and unloading sand according to the invention, after collecting the sand and sand, the carrier is moved to the inside of the frame so that the loading platform faces the lower surface of the holding plate, and then the device is driven to lower the holding plate. By pressing the top of the piled sand, the sand is shaped into a trapezoidal low packing shape, so there is no complexity as in the conventional shaping work, and as a result of facilitating the subsequent seating work, the sand From loading to shipping can be done efficiently in a short time, and labor can be saved.

Further, the shaping operation consolidates the earth and sand, so that the load weight can be appropriately maintained even when the packing shape is low, and spillage of earth and sand during transportation can be prevented.
