A device for preparing soil for domestic plants contains a cylindrical casing, the outer surface of which is covered with a layer of heat-insulating material, a loading hopper, an unloading window mounted inside the casing with the possibility of rotation from the drive transporting working body, heating elements placed on the outer surface of the casing under a layer of heat-insulating material. The transporting working body is made in the form of a screw. The loading hopper is divided into compartments, each of which is equipped with a shutter. The transporting working body is installed under the loading hopper from its outer edge to the outer edge of the discharge window. The screw is made with a variable pitch of turns. The step of the turns of the part of the screw located under the loading hopper is made smaller. The step of the turns of the part of the screw located from the loading hopper to the outer edge of the discharge window is made large. The screw turns are made with breaks of equal width, which are located radially and at an equal distance from each other. The quality of soil preparation is improved.

Description

The utility model relates to agricultural machinery, in particular, to devices for soil preparation.

A device for preparing soil for domestic plants is known [A device for preparing soil for domestic plants. - Patent RU 2548885. - Publ. 04/20/2015, Bull. No. 11], comprising a cylindrical casing, the outer surface of which is covered with a layer of heat-insulating material, a loading hopper, an unloading window, a transporting working element mounted inside the casing with the possibility of rotation from the drive, heating elements placed on the outer surface of the casing under a layer of heat-insulating material, transporting the working body made in the form of a screw installed between the outer edge of the discharge window and the inner edge of the loading hopper, in a casing under the loading hopper with the possibility rotation capacity from a drive shaft mounted on the outer surface of which is equidistant from each other along a helical line radially mounted blades, which plane coincides with the direction of the helix, the hopper is divided into sections, each of which is provided with a damper.

The known device has the disadvantage of low quality soil preparation.

The technical result achieved by using the utility model is improving the quality of soil preparation.

The technical result is achieved by the fact that the transporting working body is installed under the loading hopper from its outer edge to the outer edge of the discharge window. The screw is performed with a variable pitch of turns. The step of the turns of the part of the screw located under the loading hopper is performed smaller. The pitch of the turns of the part of the auger located from the loading hopper to the outer edge of the discharge window is large. The turns of the screw are performed with breaks of equal width, which are arranged radially and at an equal distance from each other.

In FIG. 1 shows a General view of the device.

A device for preparing soil for domestic plants contains a cylindrical casing 1, the outer surface of which is covered with a layer of heat-insulating material 2, a loading hopper 3, an unloading window 4 mounted inside the casing with the possibility of rotation from the drive 5 transporting working body 6, heating elements 7, placed on the outside the surface of the casing 1 under a layer of heat-insulating material 2. The transporting working body 6 is made in the form of a screw. The loading hopper 3 is divided into compartments, each of which is equipped with a shutter 8. The transporting working member 6 is installed under the loading hopper 3 from its outer edge to the outer edge of the discharge window 4. The screw is made with a variable pitch of turns. The step of the turns of the part of the screw located under the feed hopper 3 is made smaller. The step of the turns of the part of the screw located from the loading hopper 3 to the outer edge of the discharge window 4 is made large. The turns of the screw are made with breaks of equal width, which are located radially and at an equal distance from each other.

The device operates as follows. Turn on the heating elements 7. After reaching the required temperature of the casing 1, turn on the drive 5 of the transporting working member 6. The valve 8 controls the ratio of the supplied components for soil preparation from the loading hopper 3. In predetermined proportions, the components enter the casing 1, where they are captured by turns of the screw that moves these components in the direction from the loading hopper 3 to the discharge window 4. Due to the smaller pitch of the turns of the part of the screw located under the loading hopper 3, in this zone s soil mixed intensively. Good mixing contributes to the presence on the transporting working body of 6 gaps of equal width, located radially and at an equal distance from each other. Next, the turns of the transporting working body 6, the step of which is made large, promote the components of the soil to the discharge window 4, while mixing them. During the movement of the mixture of soil components from the feed hopper 3 to the discharge window 4, it warms up to the required temperature. At the same time, fungi are destroyed, when used as components of humus - eggs, worms and other harmful organisms. Finished soil is removed from the device through the discharge window 4. When changing the ratio of soil components, the position of the shutters 8 at each of the compartments of the loading hopper 3 is changed.

Installation of a transporting working body under the loading hopper from its outer edge to the outer edge of the discharge window, execution of a screw with a variable pitch of turns, in particular, its part located under the loading hopper with a smaller pitch, and the part located from the loading hopper to the outer edge of the discharge windows - with a big step, the execution of turns of the screw with gaps of equal width, their location radially and at an equal distance from each other - all this provides an improvement in the quality of soil preparation.
