UA8017U - Device for separarting impurities from roots - Google Patents

Abstract

A device for separating impurities from roots contains a feed conveyor, above a working branch of which a screw is arranged, behind which a pair of driven rollers is mounted. The screw is made as a drum, whereon spiral convolutions and cleaning resilient elements are fixed, collected from bundles ofnap, which are arranged on the surface of the drum between the spiral convolutions along the spiral line. The direction of coiling of the spiral line of the bundles of nap is opposite to the direction of coiling of the spiral line of the spiral convolutions of the screw.

Description

Description of the invention

The utility model relates to the field of agricultural machinery, especially to devices for separating impurities from root crops.

A well-known device for separating impurities from roots and tubers, which is made of a feed conveyor above which a screw conveyor is installed at some distance from the conveyor. The screw conveyor rotates to meet the movement of the conveyor with an angular velocity. Behind the screw, towards the output end of the conveyor, there is a pair of smooth cylindrical rollers, mounted one above the other and above the conveyor at some distance from it, and which rotate towards each other, with an angular velocity

The disadvantage of the known device is a small cleaning effect in conditions of excessive soil moisture - an unsatisfactory degree of separation of adhering soil on the surface of the body of root crops and plant impurities.

A known device for separating impurities from root vegetables, which contains a feeding conveyor 72, above the working surface of which a screw is placed, and the screw is made in the form of a drum, on which spiral coils and cleaning elastic elements, collected from bundles of lint, which are placed on the surface of the drum between spiral turns along a helical line. Cleaning elastic elements, which are collected from pile bundles, are located along a helical line, which has the same winding direction as the spiral turns of the auger. In addition, the stiffness of pile bundles increases in the direction of the unloading zone of the device (A.s. Mo1547752, USSR,

MKY A 010 33/08. Publ. 07.03.90. Bul. Mod).

The disadvantage of the known cleaning device is an unsatisfactory degree of separation of plant impurities in the direction of the unloading zone of the device, i.e. in the zone of descent of root crops from the output end of the feeding conveyor.

The basis of the useful model is the task of increasing the intensity of cleaning root crops from impurities, 22 by making a device for separating impurities from root crops, which contains a feed conveyor, above the working branch of which there is an auger, behind which a pair of drive rollers is installed, and the auger is made in the form of a drum , on which spiral coils and cleaning elastic elements collected from pile bundles are fixed on the surface of the drum between the spiral coils along a helical line, and the winding direction of the spiral line of the pile bundles is opposite to the winding direction of the spiral coils. in

The device for separating impurities from root crops is shown in Fig. 1 - front view, in Fig. 2 - view "-

And in Fig. 1.

The device for separating impurities from root crops consists of a feeding rod conveyor o 1, above the rods 2 of which auger 3 is installed at some distance from the conveyor 1. The auger C rotates in the direction of the movement of the feeding conveyor 1 with an angular velocity ov. Behind screw 3, towards the output end

From the feed conveyor 1, there is a pair of drive rollers 4, installed one above the other and above the feed conveyor 1 at some distance from it, which rotate towards each other with an angular speed of st. On the pipe 5 of auger Z, cleaning elastic elements b are mounted, which are collected from pile bundles 7, and the winding direction of the helical line of pile bundles 7 of cleaning elastic elements 6 is opposite to the winding direction of the helical line of spiral turns 8 of auger 3. 70 The device for separating impurities from root crops works as follows. c During the feeding of the pile to the auger 3, the components of which are root crops with and without the remains of ghee on them, soil and plant impurities and other foreign bodies, the space between the turns 8 of the auger З and the space between the auger З and the feeder is filled with material by conveyor 1. The spiral turns 8 of the auger 3, interacting with the root crops, move them to the side, that is, remove them from the feeding conveyor 1, while 15 cases of beet root crops and clods of earth colliding with the helical surface of the auger 3 are observed.

Lumps of earth are destroyed and all loose soil and small plant impurities are either sifted into the hole between the rods 2 (ав) of the feed conveyor 1, or leave it, passing through the hole between the auger З and the working surface of the feed conveyor 1. Root crops without a hook and with its residues on them, as well as impurities are moved by spiral turns 8 of screw Z along the axes of rotation of screw Z and drive rollers 4. Experiencing support from each 20 side of the newly entering pile and as it moves towards drive rollers 4, the remains of the chaff on the heads of root crops are tightened and vegetable impurities between the surfaces of the drive rollers 4 due to their opposite direction of rotation. The vegetable impurities passed between the drive rollers 4 enter the output end of the feed conveyor 1. The remains of the pulp on the root crops, being subjected to the double action of the forces of retraction by the drive rollers 4 and the movement of the root crops by the spiral turns 8 of the auger Z along its axis

Due to rotation, they are separated by the separation method and, similarly to all the last impurities, they are carried out by the feed conveyor 1 beyond its limits. In addition, the cleaning elastic elements b of pile bundles 7 interact with the body of root crops, while cleaning their surface from adhering soil and, due to the winding of the helical line of the pile bundles 7 in the opposite direction of the winding of the helical line of spiral turns 8 of auger C, move plant impurities in the opposite direction unloading zone of the device, that is, in the direction opposite to the movement of root crops, increasing their time spent on the cleaner.

Thus, due to the installation of cleaning elastic elements b, which are collected from bundles of pile 7 on the drum 5 of the auger 3, the process of separating impurities from root crops is intensified. b5
