RU94796U1 - DEVICE FOR GRINDING SEEDS - Google Patents

Abstract

 A device for grinding seeds, comprising a loading hopper with a control flap, a housing, a rotating grinding drum and a fixed deck, a fan for removing impurities, an electric drive, an exit for polished seeds and an exit for light impurities, characterized in that the drum is made of a set of grinding abrasive wheels with a diameter of 350 -400 mm, and the deck is equipped with an abrasive coating with a drum angle of 60 ° and is set with a gap relative to the drum, depending on the size of the treated seeds.

Description

The utility model relates to machines for agricultural engineering and can be used for pre-sowing grinding seeds of fodder beets.

For sowing the seeds of fodder beets with precision seeders, the material must undergo additional processing-grinding, in order to free it from impurities and isolate one or two-germ seeds. At the same time, the ribbed parenchymal part of their pericarp is removed from the seeds of fodder beets, which ensures a more rounded shape of the seeds, their better fluidity during sowing, and ensures an increase in crop yield.

For this operation, a selection-seed breeding crab is used. (Industrial technology for the cultivation of fodder beets. M.: VIM.-1986.-73 s. Agricultural machinery. Catalog. Volume 2.M .: INFORMAGROTEH -1991.-369 s.)

The device consists of a receiving hopper, a frame, a housing with a shutter, a shaft assembly with fingers of a pin strip, a bucket drive for collecting seeds and a table.

The seed material is poured into the receiving hopper, from where it flows by gravity into the upper part of the inclined body and moves inside the pipe to the discharge window. In the process of moving through the pipe, the fingers of the rotating shaft and the pin bar act on it, due to which the seeds are ground.

However, the process of seed treatment with this device is chaotic in nature: it is inefficient and does not provide high-quality preparation of seed material.

A device for grinding seeds is known, containing a loading device and an organ in the form of a screw enclosed in a casing, the screw being divided into sections using washers of the same diameter and the diameter of the turns of the screw of each subsequent section is larger than the previous one, and the gap between the casing and the subsequent washer in the same direction made decreasing due to the increasing inclination between each subsequent washer and the screw shaft and the washer of the last section is set at an angle of 90 ° to the shaft. The degree of grinding is regulated by the force of the spring preload of the outlet valve, made in the form of a solid disk, the plane of which provides grinding of the seeds.

The device is equipped with an electric drive. (A.s. 1766295 A1 USSR MKI A01C 1 \ 00 Device for grinding seeds / Lastovenko V.A., Kondratyev I.O., Kovalev V.G. et al. (USSR) No. 4883868/15; claimed, 2o. 112.90; publ. 07.1092; Bull. No. 37.4 p.)

The disadvantage of this device is that the device does not provide for the possibility of regulating the gap between the last washer and the bottom of the screw, which affects the quality of grinding, and the screw design of the device itself does not have sufficient task, the solution of which the claimed utility model is aimed at increasing productivity while improving grinding quality due to the regulation of the gap between the working surfaces.

This problem is solved in that the claimed utility model contains a loading hopper with an adjustable shutter, a housing, a rotating grinding drum and a fixed deck, a fan for removing impurities, an electric drive, an outlet for polished seeds and an outlet for receiving light impurities, and the grinding drum is made of a set of grinding abrasive wheels with a diameter of 350 ... 400 mm., and the deck is equipped with an abrasive coating with a drum angle of 60 degrees and has the ability to be installed with a gap relative to the drum depending sti from the size of the processed seeds.

The essence of the utility model is illustrated in the drawing, in which the device has a left view.

The solution to this problem becomes possible because the device for grinding seeds contains a loading hopper 1 with an adjustable shutter 11, a housing 2, a rotating grinding drum 3 and a fixed deck 4 with a device 10 for regulating the gap between the deck 4 and the drum 3, a fan 5 for removing impurities , electric drive 6, output 7 for polished seeds and output 8 and 9 for light impurities, and grinding drum 3 is made of a set (3 ... 5 pieces) of grinding abrasive wheels with a diameter of 350 ... 400 mm, and deck 4 is equipped with an abrasive coating m drum coverage angle of 60 degrees and is able to set the device 10 with a clearance relative to the drum depending on the size of treated seeds.

The device operates as follows

The seed to be processed is loaded into the hopper 1, having previously turned on the electric drive 6 of the device, where the seed is carried away by the rotating drum 3 and through the lumen opened by the shutter 11 enters the working gap formed by the stationary deck 4 and drum 3, where the process of grinding the seeds takes place.

Polished seeds are sent to exit 7 and then used for sowing, and the resulting light impurities are removed through exits 8 and 9.

The execution of the peeling device in the form of a rotating drum with a set of grinding abrasive wheels interacting with a stationary abrasive deck provides high productivity and quality of seed material.
