Abstract

The invention relates to a method and apparatus for casting castor beans. The goal is to improve the quality of casting the castor. The proposed method involves destroying mature bolls to tretinks, calibrating tretinks into fractions, separate threshing fractions of tretinki, while calibrating tretinki into fractions and their separate threshing is performed in a single process by successively passing tretinkas through calibrating-thick gaps, the values of which decrease during the process. For the implementation of the method serves a device comprising a pair of working bodies, formed by a convex deck and roller 3 with a gear-like surface. The teeth 4 and the cells 5 of each roller 3 are arranged alternating around the circumference and in rows alternating along the axis of the roller 3. The tooth 4 has a face 6, two lateral 7 and an outer flat 8 face. The edge of the outer face 8 of the tooth 4 in section with its plane passing through the axis of the roller 3 is located at an acute angle o on this axis. 2 sec. and 1 z. p. f-ly, 5 ill. w Ј o 00 vi o o vi

The inventions relate to agricultural production, namely to the method and apparatus for casting the castor beans, and can be used in harvesting and post-harvest processing of castor beans.

The purpose of the invention is to improve the quality of casting the castor.

The proposed method of casting the castor bean includes the following known operations: the destruction of mature bolls to tretinki; successive skip of tretinks through the calibrating-threshing gaps, the magnitudes of which decrease during the process.

To implement the proposed method of casting the castor, a suitable device has been proposed.

In Fig.1 schematically shows a device for threshing castor, a General view; Fig. 2 is a fragment of section A-A in Fig. 1; on fig.Z - drum, type of end; not figure 4 - section bb in fig.Z; FIG. 5 shows a fragment of the sweep of the toothed cellular surface of the roll.

The device includes a frame 1, located on it one above the other successive pairs of working bodies with gaps between them. Each pair of workers is formed by a convex deck 2 and a roller 3 with a gear-like surface. The teeth 4 and the cells 5 of each roll 3 are arranged alternating along the circumference and in rows with alternation along the axis of the roll 3. Each tooth 4 has an end face 6, two lateral faces 7 and an outer flat face 8. The edge of the outer face 8 of the tooth 4 in cross section its plane passing through the axis of the drum 3 is located at an acute angle a to this axis.

The gaps AL Dg, Yes between rollers 3 and decks 2 are discretely reduced from one pair to another pair of working bodies along the process, Decks 2 have elastic working surfaces. The device also includes screw pairs 9 for installation of gaps D (between the tops of the next row of teeth and the line of the convex surface of deck 2, located at the shortest distance from them), pitched boards 10, sieve 11, fan 12 with pneumatic channel 13.

The device for threshing castor works as follows.

When the tretinks enter the device, they are captured by the toothed-cambed surface of the drum 3 of the upper pair and dragged through the gauge-threshing mechanism.

AL clearance At the same time, tretinki are forced to be placed in the working gap at some acute angle between the longitudinal axis of the tretinka and the axis of the drum 3, which creates the likelihood of the working bodies acting on

the end parts of tretinki located in the zone of air gaps between the seed and the fruit coat of the tretinka, i.e., the threshing process is carried out practically without injury to the seed

The process of the hammer of the iPets is as follows. With the passage of tretinka through the first pair of working bodies with the largest gap between them (A1 mm)

medium and small tretinki passage through the gap with virtually no impact on their working bodies, i.e. not threshed, and large tretinki are hammered, the seeds isolated from them pass freely

through this gap. With the passage of the processed material through the second pair of working bodies with a smaller gap (Yes 7 mm), small tretinki and free seeds pass through it practically without the influence of working bodies, and medium sized tretinki are threshed, seeds hatching from them clearance, etc. When the processed material passes through the last pair of working bodies with a minimum gap (Dz 6 mm), which is determined by the maximum sizes of free seeds, the latter pass through the gap without affecting them by working bodies, and

fine tretinki are threshed and the seeds that have been cured from them pass through this gap.

If necessary (in the case of, for example, not ground) processed by the mother

Al can be processed repeatedly or repeatedly with the same gaps PA;) working bodies. After the tretinka passes through the cascade, the heap of steam is cleaned on the air-lattice part of the device.

The implementation of the proposed method in

The described device allows to obtain high-quality seed material at the minimum amount of laboratory and energy costs, i.e. improve the threshing process.

The results of the conducted studies have shown that the degree of glucose gum seedlings reaches 98.9%, and the injury does not exceed 0.34%
