Description

The invention relates to agriculture and can be used in winter to recover sapropel, which is used mainly as an organic fertilizer.

The purpose of the invention is to increase productivity by increasing the area of the bottom of the well and reducing the auxiliary pipe extension operations.

The sign introduced in the claims that the lower part of the screw is provided with grippers, hinged at their ends with springs acting on them, allows to increase the area of the sapropel column taken out several times due to the fact that the grippers in the working (diluted) state are loosened and pick up sapropel from a much larger area to the screw.

The screw is equipped with stoppers that hold the grips along the axis of the screw and release them by means of a flexible connection, which ensures drilling of the ice cover with a small diameter hole and opening of the catch under the ice to remove sapropel.

. The pipe stand is assembled from links that are multiples of the length of the screw, consisting of half pipes, hinged and kept locked by locks, which allows the pipe stand to be expanded without disassembling the screw itself, ensuring sapropel is unloaded through the estrus at the required height from the ice sheet.

In FIG. 1 shows a device in section; general form; Figs. 2 and 3 show the fastening of the grippers to the screw in two projections; in Fig.4 - node a in Fig.Z; in FIG. 5 and 6 are a section of a pipe stand in two projections.

ice cover; 17 - a reservoir; 18 - sapropel.

The device for extracting sapropel consists of a vertical screw 1 mounted on a self-propelled chassis 2 and ending in the lower part with a cutting crown 3. To the lower part of the screw are fixed 4 hinges 5. with springs acting on them 6. In the folded non-working position, the grippers 5 held by stoppers 7, which are mounted on the hollow axis of the screw 1 by means of tubes 8 and are pulled out by springs

9. A flexible connection is attached to the stoppers 7

10. which, through the hollow axis of the auger, is led to the upper end of the auger 1 and is fixed there on the outside of the auger. The grips 5 in the working, open state are held by the stops (not shown in the drawing) and form an angle of about 110 ... 120 ° with the axis of the screw, which allows the loosened sapropel to move along the formed funnel to the screw. The pipe stand 11 is assembled from links 12 consisting of half pipes connected by hinges 13 and held closed by locks 14. The upper link 12 is provided with estrus 15. The self-propelled chassis moves along the ice cover 16, a reservoir 17 containing sapropel deposits 18.

A device for the extraction of sapropel works as follows:

When the ice cover 16 of the reservoir 17. containing the deposits of sapropel 18 reaches the required thickness, the self-propelled chassis 2 is installed in the calculated place and, rotating the screw 1 and lowering it. begin to drill a hole in the ice. Then the screw 1 is lowered further into the sapropel 18. When the grippers 5 are below the ice, then pulling the flexible connection 10, the stoppers 7 are removed and the grippers 5 are released. The latter, under the influence of the springs 6, open. During the subsequent lowering of the rotating screw 1 and the non-rotating pipe stand 11, the sapropel is fed to the estrus 15 and further into the vehicle. In this case, the grippers 5 loosen the sapropel and feed it to the screw 1. Thus, the sapropel is excavated to the entire depth of the deposit. After excavating the column, the screw 1 is lifted. Grips 5, resting on the ice cover 18, are compressed and pass through the hole. Before drilling

another hole in a new place, the grippers 5 are compressed and fixed in this position by the stoppers 7.

Example. Mining device

Sapropel can be successfully applied for this purpose on the lakes of the central part of the Yakutsk-Sakha SSR. Thus, on Tempe Lake, located in a suburb of Yakutsk, sapropel deposits reach 5 to 12 m in thickness.

in the cold season, when the ice cover reaches a sufficient value, the device is installed in the right place. Rotating the auger and lowering it onto ice, they drill it. Then, lowering the auger to the reservoir

sapropel, having pulled for a flexible connection, release the grips and those, under the action of the springs, flow rate tf. After that, the pipe stand is installed and lowered on the screw. Further rotation and lowering of the auger

Allows sapropel to be extracted to its full capacity. After working off the column, the auger is stopped and lifted up. At the same time, the grips, resting on ice, are compressed and the screw is pulled out from under the ice .. In a further cycle to extract sapropel, they repeat in a new place.

The advantages of the proposed device are: the possibility of extracting a significant amount of sapropel from one well, increasing productivity. labor, the ability to extract sapropel from anywhere in its pool.
