A well-known soil pump, structurally made in a two-body design: with a detachable outer casing and placed inside it, made in the form of a snail in one piece with a protective rear armor plate. The inner case is equipped with a front protective bronedisk having a flange. The pump contains a shaft with an impeller mounted on it, as well as a suction and discharge nozzles. Thanks to the docking of these nodes creates a "lock" that does not allow slurry to penetrate between the buildings. For the manufacture of the inner casing, the front protective armor plate, the suction and discharge pipes, wear-resistant white cast iron is used. The front protective bronedisc is fastened to the inner case by pressing with bolts passing through the front cover fixed to the outer case, to which the back cover is also attached (patent RU 2315204 C1, publ. 20.01.2008).

A disadvantage of the known soil pumps is that they cannot be fixed to the bucket of the excavator during work.

The dirt pump shown in FIG. 1 includes a pump mounted on a common base 1, comprising a housing 2, in which an impeller 3 is mounted, protected by an armored disk 4 and connected by a shaft 5 to a drive 6, and a drilling device including a drill 7 connected by a shaft 8 with drive 9, a receiving chamber 10 located above the drill 7 and connected to the suction pipe 11 with the pump housing 2. Between the drill 7 and the working chamber 10 there is a protective mesh 12 that prevents large particles of soil from entering the impeller 3. The pump housing 2 is equipped with a discharge pipe 14.

The drive 6 of the pump can be made in the form of a hydraulic drive. The drive 9 of the drilling device can be made in the form of a hydraulic gear motor. The drill 7 can be made in the form of a plate with spikes 13.

The dirt pump is equipped with a frame designed for its mounting on the bucket 15 of the excavator (Fig. 2, 3). The frame includes two brackets 16 located at a distance necessary to install a bucket 15 between them, and consisting of a horizontal lower beam 17 made of a metal profile, one end of which is connected to the base wall 1 by an integral connection, for example, by welding, and on the other the end of which has a vertical stand 18, in the upper part of which a series of vertical holes 23 are made, and two traverses 19 made of a metal profile, at the ends of which there are mating holes 23 connected to the vertical with struts 18 using, for example, pivots for reliable fixation of the dirt pump on the bucket 15 of the excavator. Traverses 19 are provided with clamping screws 20 for mounting on an excavator bucket. Also, in the upper part of the base 1 of the dirt pump, two kerchiefs 22 are welded, having a series of vertical holes 23, similar to the holes on the vertical posts 18 of the brackets 16.

On the lower beam 17 of the brackets 16, two lodges 21 are mounted pivotally, symmetrically with respect to the transverse axis of the base, which are metal plates designed to accurately fix the position of the bucket 15 of various overall dimensions between the two brackets 16. The swivel joint allows self-adjustment of the position of the lodges 21 at different angles with respect to horizontal beam 17 of the bracket, depending on the geometric dimensions of the bucket 15 of the excavator, on which the dirt pump is mounted.

The operation of the device is as follows.

The dirt pump is brought upright and the excavator bucket 15 is lowered. Bucket 15 is installed in the cradle 21 of the beams 17 of the brackets 16, which are self-adjusting to the overall dimensions of the bucket and ensure its exact position on the brackets 16. After that, the traverses 19 are connected to the vertical posts 18 and the kerchiefs 22 using pins and clamping screws 20, which ensures reliable fixation of the soil pump on the bucket 15. The presence of a vertical row of holes 23 on the vertical posts 18 and scarves 22 allows you to change the height of the mounting beam 19, which allows placement of gr a suction pump on buckets 15 having different heights. Thus, the bucket 15 is securely mounted in a frame formed by two brackets 16 and traverses 19.

After fixing the soil pump to the bucket 15, flexible sleeves are connected to a pressure pipe (not shown) and to the drives 6 and 9 of the soil pump. The dirt pump frame is disconnected from the transport frame (not shown), the soil pump is immersed in water and put into operation. The drill 7 with spikes 13, rotating, crushes large pieces of soil to a fraction that allows the dirt pump to pump them. The soil mixture enters the receiving chamber 10, then through the suction pipe 11 enters the pump housing 2. The impeller 3, driven by the drive 6, directs the soil mixture to the discharge pipe 14. The armored disk 4 is a special means of protection that protects the working elements of the pump from the harmful effects of soil particles and thus prolongs their working life.

The inventive soil pump is designed for pumping highly abrasive hydraulic mixtures with pH 6 ... 12, density up to 1600 kg / m ³ , temperature from 278 to 343 K (5 ° C to 70 ° C), volumetric concentration of solids up to 30%, average particle size - 6 mm, maximum particle size - 85 mm, microhardness up to 11000 MPa.
