Description

The invention relates to agricultural machinery and is intended for calibrating seeds of plant origin.

A device for isolating seeds from fruits (SU No. 309694, IPC A23N 5/00 publ. 07.26.1971), containing a perforated cylindrical body, loading funnel, auger and oblique distribution plate. The screw is made in the form of a hollow truncated cone with a perforated surface, while the turns of the screw located under the loading funnel have sectional cutouts.

The disadvantage of this device is the high metal construction, low productivity and low degree of calibration.

A known prototype device for extracting pine cones from cones, cleaning and sorting them (Ru No. 212334, IPC A23N 5/00 publ. 11/27/1998), which consists of a housing with a threshing drum with a corrugated surface mounted in it, threshing the drum is made conical with a screw installed on it, under which are placed reefs made in the form of pests, and it is connected to two additional mesh drums sequentially mounted on the shaft for sorting nuts into fractions with screws installed inside them, than the first one has a screw with a winding made in the direction opposite to the winding of the threshing drum, the second has a hole for unloading the husk, and the diameter of the second drum is larger than the first.

The disadvantage of this device is low productivity due to the sequential installation of mesh drums, and low quality calibration of seeds.

The technical problem to which the invention is directed is to increase the productivity and quality of calibration of seeds of plant materials, due to the simultaneous separation of raw materials into fractions in sieve drums.

The problem is solved in that the calibration device has the shape of a cylinder with a set of calibration screens installed in it for conducting the simultaneous process of calibration and separation of plant seeds into fractions, and the loading of plant materials is carried out in a mesh drum with large holes through a slot in the side cover made over the entire diameter, and the unloading of calibrated raw materials is carried out by changing the angle of inclination of the mesh drums produced using a cardan joint of the drive shaft and a movable support mounted on the drive shaft of the mesh drums, wherein the movable support moves in the guide slot of the fixed rack.

In FIG. 1 schematically shows a device for calibrating seeds of plant origin, FIG. 2 is a sectional view of FIG. one.

A device for calibrating seeds of plant origin consists of a frame 1 on which racks 2 and 3 are fixed. On a rack 2, a platform 4 is fixedly mounted on which a gas motor 5 is installed. The gas motor 5 is connected by a shaft 6, with a safety clutch 7, which in turn is connected to the shaft 8 at the end of which a drive pulley is installed 9. The drive pulley 9 by a V-belt drive 10 is connected to a driven pulley 11 mounted on the end of the shaft 12. The shaft 12 is mounted in a support 13 which is fixedly mounted on the rack 2 and connected to the universal joint 1 4, which is connected to the drive shaft of the mesh drums 15. At the end of the drive shaft of the mesh drums 15 there is a movable support 16 installed in the slot 17 in the center of the rack 3. The slot 17 has a guide 18, in the upper part has a bend in the form of a semicircle 19, and in the lower part there is a locking support 20. A mesh drum 21 is installed on the shaft 15 for collecting a large fraction of seeds, which has a slot 22 in the cover 23 for entering the nozzle 24 connected to the hopper 25. A mesh drum 21 is installed inside the mesh drum 26 to collect the middle fraction of seeds yang, which, in turn, is installed inside the mesh drum 27 to collect a small fraction of seeds and the output of small debris into the tray 28. The mesh drums 21, 26, 27 have discharge openings with plugs 29, 30, 31 in the lid 32, respectively. Outlets with plugs 29, 30, 31 are used to discharge the calibrated product into the receiving tank 33 in turn.

A device for calibrating seeds of plant origin works as follows.

The benzomotor 5 mounted on the platform 4 is fixedly mounted on the rack 2, which in turn is mounted on the frame 1. The benzomotor 5 transmits torque to the shaft 6, through the clutch 7 to the shaft 8 at the end of which the drive pulley 9. The drive pulley 9 through a V-belt drive 10 transmits torque to the driven pulley 11 mounted on the end of the shaft 12. The shaft 12 mounted in the support 13 through the cardan drive 14 transmits torque to the drive shaft of the mesh drums 15 which drives the rotator net movement of the mesh drums 21, 26, 27. Vegetable raw materials for calibration for calibration comes from the hopper 25, then through the feed pipe 24 the raw material enters the inside of the mesh drum 21, to ensure the operation of the feed pipe 24 in the cover 23 of the drum 21, a through slot 22 is made. When the drive shaft of the mesh drums 15 is rotated and the mesh drum 21 is rotated, the raw materials are evenly distributed over the entire area of the mesh drum 21 from the cover 23 to the cover 32, while the raw materials are mixed and the middle and fine fractions wake up from the mesh of the drum 21 and after calibrating the raw material, the coarse fraction remains in the drum 21. The middle and fine fractions wake up in the mesh drum 26 where, after calibration, the middle fraction remains, and the fine fraction wakes up in the mesh drum 27, which divides it into a small fraction of seeds and small residues garbage pouring into the pallet 28. To unload a large, medium and small fraction of seeds, a movable support 16 installed in the slot 17 is made in the rack 3, along the guide 18 is lowered from the working position made in the form of a semicircle 19 in position ygruzki to lock the support 20, thus changing the angle of mesh drums 21, 26, 27 and open outlet opening with plugs 29, 30, 31, alternately seeds discharged into the receptacle 33.
