SU1210704A1 - Method of separating root vegetables from soil clots and stones - Google Patents

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to machines for the separation of root and tuber crops from earth and stone clods.

The aim of the invention is to increase the productivity and quality of the separation of the root-and-vegetable crops, as well as to reduce their damage during the separation process.

FIG. Figure 1 shows a diagram of the separation of root crops by the proposed SPNN, where they lose their flight speed. Lumps of earth and stones enter the field along a trajectory 5.

The angle of incidence of the pile component on the drum is 30-75 ° to the horizontal plane, or 15-60 ° to the tangent plane at the point of impact on the cylindrical surface. This angle is chosen from the following, its conditions: if the linear speed of the drum surface is stable; in fig. 2 - angles; the feed rate increases the feed rate of components by 1.3 times by. cylindrical drum. due, the angle of incidence should be 30 °, if

The method is carried out as follows: the speed of the surface of the drum is approximately 60%. It is more than the feed rate of the components in a 2.1 podoped-up tuber-containing mass, the angle of incidence should be 75 °. It is delivered to the feed mechanism 1 in the difference of the linear velocity of the surface of the loosened state, from where the hard drum 2 is comparatively rotating at the bottom of the slave at least 1.3 times. the cylindrical surface of the root crops, clods of earth and stones bounce on

different distance, since the coefficient-Q of a raban is not more than 2.1 times compared to the recovery method they have not the same, at the rate of supply of the components, the example of root and field crops is determined as a more elastic limitation of the rate of reflected tubers bounce further. to reduce damage to the latter.

Root and club crops reflected from the cylindrical drum, earth lumps and cham- ems. In general, an increase in the linear velocity does not move along definite trajectories m, 25 of the surface of the cylindrical drum along planes perpendicular to that compared to the feed rate of the prednazerny axes of the drum; started to impart flight paths, the optics fall onto the conveyor belt of the root and tuber crops; the terrain storage 3 is located along the trajectory 4 located in a plane perpendicular to the axis of the x planes of the drum.

the flow rate of the components avoids collisions between the fed and reflected components. Increasing the linear velocity of the surface of the base, the angle of incidence should be 75 °. The increase in the linear velocity of the surface of the drum is not less than 1.3 times compared to

no more than 2.1 times the feed rate of the components due to the speed limit of the reflected tubers to reduce damage to the latter.

the flow rate of the components avoids collisions between the fed and reflected components. Increase the linear velocity of the ba surface

Claims (1)

METHOD FOR SEPARATING ROOT TERRITORY FROM LODS OF LAND AND STONES, including the supply of a heap to a horizontally arranged reflective surface, made in the form of a rotating cylindrical drum, the collection of components of the heap in various places and their transportation, characterized in that, in order to increase the productivity and quality of separation, as well as reduce damage to root crops, the heap is served continuous flow at an angle of 30–75 ° to the horizontal plane, and the drum is rotated with a linear surface velocity, 1.3–2.1 times the feed rate of the components.
