DE1006642B - Device for draining soil, especially moorland - Google Patents

Description

The invention relates to the drainage of soils, in particular peat soils.

It is well known that bog areas can absorb large amounts of rain, which they then only slowly return hand over. The large amounts of water stored in the peatland reduce the load-bearing capacity of the The bog soil is considerable, which hinders the cultivation of the soil and the removal of the soil will. In addition, the over-wet soil endangers the growth of the plants. One is therefore strives to accelerate the natural water withdrawal through drainage measures.

The methods previously known for drainage and drainage and individually listed below have not proven to be very effective in peatland soils, as they are sometimes too expensive and sometimes only applicable to a limited extent.

The drawing of open trenches brings loss of terrain, makes the installation of the access roads more expensive and requires a lot of work for the current one Keeping the trenches clean.

The laying of drainage pipes avoids the aforementioned disadvantages, but is because of the high Material and labor costs for the manufacture and laying of the clay tubes and those supporting them Slatted frames for bog soils are uneconomical.

Also the drawing of narrow, slot-like trenches, the upper end of which is then separated from one side edge of the trench by a device for drainage that is cut off with an inclined knife and then slightly to the side
of soils, especially peat soils

In the new device for drawing underground drainage channels in peat soils are on a vehicle arranged, continuously operating conveyors used in a housing are housed behind a pushing the ground apart as the vehicle moves forward Hexagon is arranged.

Such devices are known per se for the excavation of deeper layers of useful soil, slipping, wedge-shaped soil piece is covered, 30 A known device of this type works with has not proven to be the perfect solution to the moor - a pipe arranged behind the hexagon in drainage problems, since the wedge piece which is operated by a screw conveyor, which is provided with a digging head at its end that is slightly disintegrated during agricultural work. A can interfere, so that the slit-like trench _w ith a screw conveyor provided tube but must revert. When not used for agriculture, 35 still have a considerable diameter. It must also abzutorfendem terrain can, moreover, the slot-j _n a fairly acute angle with the direction of travel

Cavities have also proven to be difficult to use for draining 40 heavy equipment to the bog soil, as they penetrate the soil and are therefore only intended to be driven by pulling through one at the bottom for mushy and sandy soils, in which one end The cavity formed by a six fortified torpedo-shaped body would collapse immediately. If, through displacement of the soil below the ground, such a cylindrical cavity, which is inclined at an angle to the front, encounters a stump or other obstacles often present in bog soils for a relatively short time due to the elasticity, it becomes deeper into that of the bog soil closes again and thereby a
calls into question sufficient water supply.

The new device for clearing a drainage line eliminates the disadvantages of the previous known methods, by creating a layer below the top layer of soil that is not caused by soil displacement, Instead, it creates hollow space by clearing out the D rai.

In another known design for conveying layers of useful soil to the surface, a bucket elevator is used used, which is arranged in a rotatable tube inserted obliquely into the ground in the direction of travel which is provided with digging tools. With

However, digging pipe devices cannot create a subterranean cavity because the churned up Slip the bottom of the upper layer of soil into the space created by excavating the lower layer will.

In contrast to the two devices described above, according to the invention a scraper belt is arranged as a conveying device within a narrow housing provided with the hexagon, its lower part below, corresponding to the height of the drainage line to be cleared the hexagon protrudes and its lower sprocket is mounted in the housing.

Thanks to the arrangement of a scraper belt that appears to be planing and that runs at very high speeds can circulate, the bog soil is crushed to a much greater extent than with slowly rotating grave heads or bucket elevators. The small width of the scraper belt enables the coulter housing to do so to keep narrow that the grown soil closes ao behind the housing with certainty. It can So no soil can fall through the six-gap into the excavated underground cavity.

A transmission is preferably provided between the conveying device and the clearing device. It is advisable to create wider drainage channels in other types of digging devices as is known, on both sides of the lower end of the scraper belt, screws with opposite pitch to arrange.

An embodiment of the invention is described below with reference to the drawings. It shows

Fig. 1 is a schematic representation of the new drainage device in a sectional view, which is placed through the median longitudinal plane of the six,

FIG. 2 shows a schematic sectional view along line 2-2 of FIG. ₁

3 shows a schematic sectional view along line 3-3 in FIG. 1.

For the sake of simplicity of illustration, the chassis carrying the drainage device and the on This chassis located drive device for the drainage device is not shown because a Chassis of any type and also a drive device of any type can be used. For example, the drive device can be used both for driving the chassis and for the Serve drive the device.

The device essentially consists of the conveying device arranged behind the coulter 10 11 and the clearing device 13 clearing out the actual drainage channel 12.

In the exemplary embodiment shown, a conveyor device provided with blades 15 is used as the conveyor device Scraper belt 14 is used, which is from an upper one with a drive device indicated schematically in FIG 16 coupled sprocket 17 is driven. The lower driven sprocket 18 of the The scraper belt is supported on the coulter 10. The coulter 10 is preferably designed in the form of a housing and envelops the part of the conveyor that lies behind it.

The raking consists in the embodiment shown of two augers 19 and 19 ^e, act whose screw in opposite directions and carry out the soil components of the conveyor lying between them covered by them, which promotes the evacuated soil particles upwardly where they in some way behind or beside the conveyor be thrown off.

Constructive details of the worm worms, the worm gear drive, the possibly between the worm gears and the lower sprocket existing gear etc. are not detailed shown.

From the foregoing, the operation of the device described is readily apparent. The device mills a cavity with its two augers and with the lower part of its scraper belt through the moorland. The cross-sectional shape of the cavity is essentially rectangular, can but can also be designed differently through a special design of the snails. The one between the cavity and the moor layer lying on the surface of the earth is kept relatively narrow by the hollow six cut and pressed to both sides. Due to the elasticity of the moor the slot closes immediately after the six has passed. So it stays between that Cavity 13 and the surface of the earth are the full height of the grown bog.
