Abstract

The invention relates to the mechanization of forest and agricultural production and can be used to create machines to bare and deplete the fruits of desert plants. The purpose of the invention is to improve the quality of processing of seeds of desert plants from bristles and wings. The device contains. Installed over an inclined sieve (P) a conveyor and a seed bin. The P is connected with the frame by mechanisms that ensure its oscillations in the vertical and horizontal planes, and consists of working 14 and loading 10 parts. The loading part P has elongated holes with bent edges 12 located at an angle to the longitudinal side of P, in the form of longitudinal strips. The working part 14 P has holes 15 of rectangular shape with a pointed cutting edge. Seeds from the hopper are fed to P, which oscillates in the vertical and horizontal planes. Seeds under the action of the forward speed of the conveyor and the additional speed from the influence of the edges 12 roll over them to the working part P. The coupled seeds are separated because the speed on the strips is greater than on the smooth Surface p. The presence in the working part P of holes 15 with sharp edges ensures the removal of bristles and cavities from seeds, which gives them an increased flowability. 4 il. . i (L to; & i4 lN5 MS

Description

The invention relates to the field of mechanization of forest and agricultural production, can be used to create machines for uncovering and leafing fruits of desert plants, mainly dzhuzgunov (Kandymov) and is an improvement of the invention according to the author. St. No. 1242107.

The aim of the invention is to improve the quality of seed treatment empty. plants from wing setae.

Figure 1 shows the proposed device, a General view; figure 2 is the same, top view; fig.Z - resolutely, a general view; figure 4 - section aa in figure 3.

The proposed device (figure 1) consists of a frame 1, a conveyor 2, oscillating sieve 3, a hopper 4, an eccentric shaft 5, a crankshaft 6, load rollers 7, a drive 8 mechanisms movable in a vertical plane, frame grooves 9. Frame 1 is the base on which all other device nodes are mounted.

Conveyor 2 is an endless rubberized band, pulled over two drums. Inside the conveyor 2 are loaded rollers 7, clamping the tape to the oscillating sieve 3, which consists of two parts. The loading part 10 occupies the 1 / 4-1 / 5 part of the surface and has oblong holes 11 with bent edges 12 located at an angle of at least 0.72 rad to the longitudinal side of the sieve with a distance between them of 15-18 mm in the form of longitudinal strips 13 .

The sieve working part 14 has holes 15 of rectangular shape with a size of mm. The long side of the hole is oriented along the direction of movement of the mass of fruits and has a pointed cutting edge. The sieve and conveyor belt are located at an angle to the horizon, with the sieve in the lower part fixed pivotally.

The hopper 4 is located above the screen and has a portion of the feed feeder 16 for a more uniform supply of the original pile into the work area. The installation is set in motion by an electric motor and a wedge-gear system 8.

The device works as follows.

From the bunker 4, the seed heap gets onto the oscillating sieve 3, from where the fruit rolls and is pulled into the work zone by the conveyor belt 2. At the same time, sieve oscillations in the vertical plane facilitate better passage of the fruit into the working area. The conveyor belt 2 performs a translational motion, and the oscillating sieve 3 performs a reciprocating movement in the horizontal plane in the slots 9 of the frame 1. The oscillating sieve 3 from the crankshaft 6 oscillates in the direction perpendicular to the movement of the conveyor belt 2.

 In addition, the sieve makes oscillatory movements in the vertical (PLANE from the eccentric shaft 5.

When the conveyor belt 5 5 moves in an intense oscillation of the sieve 3, equipped with cutting edges, the fruit between these planes will continuously experience an effect from their side. The transfer ribbon is the element that presses the fetus to the sieve, and the edges of the patch are the active element. The frequency of oscillations of the sieve depends on the quality of fruit bare.

J With the upper position of the eccentric throughout the working area, the size of the gap H is constant, but with its lower position (FIG. 1), the gap H becomes much larger, and

0 is much larger than the size of the lowered fruit.

At the time when the eccentric is in the lower position, the grating sieve moves in the horizontal plane in direction A (Fig. 3). Fruits enter the working gap. Then, turning, eccentric shaft 5 occupies the upper position, the lowered fruits rise

0 by the sieve to the conveyor belt 2, a better condition is created for advancing the fruit to the main working sieve. At the same time, the grating in the horizontal plane makes

5, movement in direction B (FIG. 3) and then bent edges, which, acting on the preloaded fruits, push them further into the working area, are activated, so that the fruits are pushed.

Moving due to the translational speed of the conveyor belt and the additional speed obtained from the effect of the edges on the fruits, it is possible to roll them towards the working area, but not backwards.

On the grooved strip, the rate of fruit admission to the working area is more than smooth. In this case, an additional separation of the adhering fruits occurs, and, falling on a smooth surface, the fruits under the action of the conveyor belt are carried away only in the longitudinal direction, which prevents the fruits from coming off the sieve, beyond its longitudinal side.

The presence of cutting edges on the sieve ensures the removal of bristles and krylatok from the surface of the fruit due to the fact that during sieve oscillation and movement

the conveyor belt rotates the seeds, in which the bristles and wings are cut with a cutting edge. The fruit gradually becomes exposed, which, in turn, gives the fruit an increased flowability. g
