Abstract

Usage: in agricultural machinery, in particular in devices for grinding seeds. SUMMARY OF THE INVENTION: the device comprises a supporting working element in the form of a disk, disks with an abrasive base on an elastic substrate are uniformly mounted over the peripheral part of it. The disks relative to the working body are arranged with a smaller clearance as the seeds are ground and communicated with guides 12, the gap between which decreases from the previous one in the process of moving the seeds of the disk to the next. The drives of at least two adjacent disks are designed to provide their opposite rotation. Each previous disk in the direction of rotation is located between the ends of the rails located at the maximum distance from each other. The other ends of the guides for the multi-drive discs are placed on different sides of the circumference of the installation of the latter in order to provide in these areas counter-impact on the seeds of the support and drive discs. 2 ill.

Description

The technical solution relates to agricultural machinery, in particular to machines for grinding seeds.

The purpose of the invention is to improve the grinding quality of seeds.

The seed grinder of FIG. 1 and 2, comprises a frame 1 with a supporting member in the form of a disk 4 arranged by means of a bearing support 2 and a shaft 3, over the peripheral part of which, on the shafts 5, working bodies in the form of disks 6 with an abrasive base 7 glued on elastic substrate 8. At the first along the movement of the seeds of the disk 6, a hopper 9 is mounted. The disks 6 are located relative to the support member 4 with a clearance 10 decreasing as the seeds are ground, which is regulated by the nut 11 of the screw mechanism. Adjacent discs are connected by guides 12 adjacent to the surface of the support member 4 and mounted at an angle to each other. Each previous one, starting from the first, in the direction of rotation of the support member 4, the drive disk is located between the ends of the rails 12. The other ends of the rails are oriented in

well, where the rotations of the supporting and working bodies are opposite, i.e. depending on the direction of rotation of the working body 6, they are placed on different sides of the circumference of its installation.

The disks 6 and the guides 12 are placed between the rings 13 and 14, which are respectively fixed on the frame 1 centrally and around the perimeter of the support member 4 and also abut against its surface, the diameter of the disks 6 being comparable with the distance between the rings. Behind the latter, in the direction of movement of the seeds by the disk b in the ring 14, a window 15 is made, in which a collider 16 is installed across the seed current.

For rotation of the disks 6 and the supporting working member 4, an engine 17, a gearbox 18 and chain transmissions 19, 20 are provided.

The number of discs is related to the size of the seeds and the layer removed from them. The rotational speed of the subsequent disc is chosen equal to or greater than the rotational speed of the previous disc. The drives of at least two adjacent discs are designed to provide their opposite rotation.

The device operates as follows. The support member 4 and discs 6 are rotated. The processed granular material is fed uniformly from the hopper-dispenser 9 to that part of the supporting working body 4, which is limited by rings 13 and 14 and transported under the first seed disk 6, from under which the seeds are guided by 12 using the guides 12 under the next disk 6 into the zone of counter impact on the seeds of the support and drive discs and then, similarly, until the seeds are unloaded through the window 15 into the storage hopper 21.

The complex movement of seeds performed in this case ensures maximum

the length of the advancement of the granular under the discs 6. located with decreasing clearance relative to the organ 4, which substantially determines the quality grinding of the seed material, which is also positively affected by the uniform pressure of the abrasive base 7 on the seeds due to the elastic substrate 8.

The described device eliminates mechanical damage to the seed and obtain high-quality polished seeds, which increases their field germination.

Claims (1)

The claims A device for grinding seeds, comprising a support member in the form of a drive equipped with a rotation disk and working bodies in the form of drive discs mounted above it around the circumference, arranged relative to the support member with a clearance decreasing in the direction of movement of the seeds, and guides, characterized in that in order to improve the quality of grinding the seeds, the guides are installed at an angle to one another and are located between the working bodies, while the drives of at least two adjacent disks are made to provide their opposite rotation, each previous disk in the direction of rotation is placed between the ends of the rails located at a maximum distance from one another, and their other ends for drives with different drives are placed on different sides of the circumference of the installation of the latter to ensure these areas of counter action on the seeds of the supporting disk and the drive disk. 16 # 12
