Abstract

The invention relates to agricultural machinery and is intended for the post-harvest processing of grain mixtures. The goal is improved quality and separation performance. For this, the friction surface (FP) 1, which is equidistantly mounted over the longitudinal inclined direction (FP) 1, and the reflective FP 6, is made in the form of an endless belt (BL). The direction of the working rotation of the tape is perpendicular to the longitudinal axis of the working OP 1. Along the transverse sides of the OP 1 and along the longitudinal side of the OP 1, collections of 13, 14 and 15 - 17 separation products are installed. The source material is supplied between OP 1 and 6 by the device 9. Due to the directional oscillations created by the vibration exciter 2, the particles are detached from the OP 1 and fly. When flying, they collide with the OP 6, which gives them a counter-pulse. Seeds are moved not only down to receiver 13 and up to core 14, but also in the direction of movement of the lower branch of BL to receivers 15 - 17. Simultaneously with an increase in the "fan" of seed trajectories with different properties, the probability of their collisions and mutual depletions decreases. opposite faction. This allows you to increase the supply of seeds to the working OP 1. 2 Il.

Description

1

The invention relates to agricultural machinery, in particular, machines for the post-harvest processing of grain mixtures, and can be used in the chemical and mining industry for the separation of bulk materials into fractions according to a complex of physicomechanical properties.

The aim of the invention is to improve the quality and performance of the separation.

The invention is illustrated in the drawings: in FIG. Figure 1 shows the design (the vibraseparator circuit is used. 1. In Fig. 2 - the same, top view.

The separator consists of a longitudinally inclined friction working surface 1, a vibration exciter 2, a vibration platform 3, which is mounted on frame 5 by means of springs 4, a reflective friction surface 6 established by equi-jn, HC iaHTno above surface 1 and made | in the form an endless belt, the direction of the working rotation of which is perpendicular to the longitudinal axis of the surface 1, the mechanisms 7 and 8 for adjusting the gap between surfaces 1 and 6 and their angle of inclination to the horizon, and tools 9 for feeding the source material between the surfaces Tips 1 and 6. Surfaces 1 and 6 are installed under the ANGLE and to the horizontal with a rise in the direction of the vibration exciter 2. The vibration exciter 2 is driven by this AC electric motor 10 through the speed variator 11 and the V-belt transmission 12. The output of the selected fractions is carried out The main collections 13, 14 are located along the transverse sides of the surface 1 and the additional collections 15, 16 and 17, along the longitudinal side surface 1 along the movement of the working lower branch of the belt 6.

The process of vibroseparator proceeds as follows.

The treated seed mixture from the feeding device enters the working friction surface 1, which is set at an angle a to the horizon. Due to the directional vibrations created by the vibration exciter 2, the particles are detached from the working surface and fly. In the lifting phase, they collide with the reflective surface 6, which informs them of a counter shock pulse. At the same time, by using an endless belt as a reflective surface with a direction of rotation perpendicular to the longitudinal axis of the working surface, the seeds move not only downwards

trajectories 18 (more elastic, smooth, rounded) to receiver 13 and upwards along trajectory 19 to receiver 14 (flatter, inelastic, rough), but also in the direction of movement of the lower branch of the endless belt, along route 20 to receivers 15, 16 and 17. Taking into account the fact that any seed mixture contains not only more elastic and less elastic components, but also particles with intermediate values of these properties, it becomes obvious that the design of the vibroseparator makes it possible to obtain several fractions of seeds by increasing the with m n. It is known that the quality of separation is higher, the wider the "fan of the trajectories of motion

Q separable fractions of seed mixture. Simultaneously with the increase in the "fan of the trajectories of seeds with different properties, the probability of their collisions and mutual engagement in the opposite fraction decreases, which allows an increase in the flow of seeds
