    The invention relates to the technique of separating grain mixtures and can be used mainly in agriculture for the exact grading of grain,
    A device for sorting grain is known, comprising a housing in which calibration cylinders and a cleaning mechanism mounted on an axis installed in a housing above cylinders, as well as a feeder and means for removal of CO fractions are mounted
    The mounting structures of the {Cylinders and the axis of the cleaning mechanism in this device do not provide the possibility of a quick replacement of the cylinders. The need for such a replacement is dictated by the fact that the grain classification of corn | 1 of corn, wheat, rye, rice, soybean, grass seed, coffee beans, etc. is accurate. requires the use of different calibration cylinders with different orifice sizes.
    It also includes a device for sorting grain material, comprising a housing in which a calibration cylinder is located, having rims and a cleaning mechanism mounted on supporting rollers, mounted on a shaft mounted in the housing above the cylinder, a feeder material and means for removing C 2 fractions.
    A disadvantage of the known device is also the difficulty of replacing the calibration cylinder, as in the process of dismantling the cylinder, it is first necessary to disassemble the cleaning mechanism and then chain or belt drives or gears, which require the involvement of qualified personnel.
    The purpose of the invention is to simplify installation and removal of the device.
    The goal is achieved by the fact that, in the device for sorting grain material, the cylinder is mounted on rollers freely, at least one of the rollers, the number of which is four, has a rotational drive, and the casing is provided with a removable longitudinal wall and radially relative to the axis of the cylinder The shaft of the cleaning mechanism is installed in these guides by means of bearings.
    In addition, the support rollers are arranged in pairs on each of the end sides of the cylinder.
    The rotational drive supporting roller is made with a wedge-shaped profile, and in the rim corresponding to this roller, a groove is formed around its circumference.
     The shaft of the cleaning mechanism has gear wheels coupled to the rim of the shchindra.
    The support rollers and transmission wheels are made of rubber, and the cylinder rims are made of wear-resistant plastic. i The cleaning mechanism is designed as a brush. In addition, the device is equipped with a vane shaft, placed inside the cylinder and fixed on its front sides. FIG. 1 shows a device for sorting bulk material, a longitudinal section; in fig. 2 - the same top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. one; in fig. 5 - the device with an open longitudinal side of the body during dismantling, clean the mechanism; in fig. 6 - the same, at the time of dismantling the calibration cylinder; in fig. 7 is a schematic diagram of the installation of the cleaning mechanism and the calibration cylinder; in fig. 8 is a section bb of FIG. 7; in fig. 9 - cleaning mechanism installed in guides; in fig. 10 is a flow chart for calibrating seeds using the proposed devices. The device for sorting bulk material includes a housing 1 installed on supports 2 and 3 and having a material feeder with an input A. Means for withdrawing fractions are made as an outlet 5 for a waste product and mounted on the underside of the housing 1 exhaust funnels 6 and 7 for screenings (through products). From above, the housing 1 is closed with a curtain 8. The inlet 4 is rigidly fixed on the end wall 9 of the housing 1, and exit 5 on the end wall 10. The distance between the discharge end of inlet 4 and the loading end of the cylinder 11 in order to facilitate installation and disassembly of the latter is less the distance between the discharge end of the cylinder and the tapped surface of the end stack 10. The calibration cylinder 11 contains a separating drum 12 with holes 13 or a wire grid. On the drum 12 mounted rims 14 and 15, made preferably of wear-resistant plastic,
    The rim 14 is fixed to the drum 12 by means of an elastic clamping washer 16 mounted with the help of its shoulders 17 and the clamping nut 18 on the blade shaft 19 with blades 20, which is located inside the cylinder 11 and coaxially with it. Rim 15 is mounted
    The support roller 25 has a drive wheel, a puppy containing a motor 35 equipped with a gearbox and a chain drive with a chain 36 and sprockets 37 and 38.
    Sprocket 38 is rigidly mounted on the shaft 26.
    The gear wheels 33 and 34 can be made of plastic or re84 on the drum 12 by means of a clamping star 21 welded to the blade shaft 19. Thus, the latter is a means of transporting the free-flowing material in the drum 12 with one stoone, and on the other hand, together with the clamping washer 16 and the clamping star 21, is a means for mounting the rims 14 and 15 on the drum 12. The calibration cylinder 11 is mounted on four coaxially arranged rollers 22, 23 and 24, 23 and the rollers 22 and 25 They are on one side of cylinder 11, and rollers .23 and 24 are on the other. The support rollers 23 and 24 mated with the rim 14, as well as the roller 22 mated with the i5 rim, have cylindrical working surfaces. The roller 25 is made with a wedge-shaped profile, and in the rim 15 corresponding to this roller, a wedge-shaped groove is made around the circumference. The rollers 24 and 25 are rigidly mounted on the shaft 26. The cleaning mechanism mounted on the shaft 27 mounted in the housing 1 above the cylinder 11 can be made in the form of removable plastic plate beaters 28 or in the form of a brush 29. The shaft 27 of the cleaning mechanism is installed by means of two bearings 30 rolls, each of which is slidably positioned inside the radially relative to the axis of the cylinder 11 and the guide 31 open from above. Each guide 31 is fixed by screws 32 on the corresponding end wall 9 or 10. Thus, the shaft 27 is The mounting mechanism is mounted in the housing 1 with the possibility of radial movement relative to the axis of the cylinder 11 of displacement. On the shaft 27, gear wheels 33 and 34 are rigidly mounted, mated respectively with rims 14 and 15. Wheel 33 has a cylindrical working surface, and wheel 34 has a wedge-shaped one that is coupled with a wedge-shaped rim groove 15. Eine, and rollers 22 and 23 are plastic , support rollers 24 and 25 are preferably rubberized. 1 The rollers 22 and 23 are rotatably mounted on pins 39 connected to the housing 1. The housing 1 has a removable longitudinal wall 40 fixed to the housing by means of a quick-acting shutter 41 and mounted on the lower holder 42. The housing 1 can be made with opposite longitudinal walls 40 (Fig. 3). Two cylinders 11 (FIGS. 5 and 6) can be installed in the / one housing 1. The proposed device for sorting bulk material can be used in the process line for seed calibration. This line contains blocks 43 and 44, each of the KOTO units consists of four parallel cylinders 11, blocks 45 and .46, each having two cylinders, a separator 47 with one cylinder, trireors 48-50 and cells 51 for storing the target products. During the operation of the proposed device, the torque generated by the engine 35 is transmitted through a chain transmission of sa with asterisks 37 and 38 to the drive bearing rollers 24 and 25, which cause the cylinder 11 to rotate. At the same time, the rims 14 and 15 and the transmission wheels 33 and 34 rotate the rotation cleaning mechanism. The grain material fed through the inlet 4, for example corn corn, enters the cavity of the cylinder 11. Together with the latter, the rotating blades 20 are immersed in the material and propel it along the cylinder (in the axial direction). Maize coarse grains fall into Exit 5, and light (pass) fractions fall into Exhaust Funnels 6 and 7. In the sorting process, as the shaft 27 rotates the cleaning meats (the blow 28 or the brush 29 cleans the separating drum surface 12 from the grains stuck in the holes 13. Since the hammer 28 was made elastic of soft material (made of leather or rubber), the possibility of damage or deformation of the separating surface, the holes 13 of which were made with high precision, was excluded. long-term operation, the wear of the working surfaces of the rims 14 and 15 of the support rollers 22-25, as well as the transmission wheels 33 and 34, does not have any negative effect on the driving of the cylinder 11 and the cleaning mechanism during rotation, since the cylinder 11 under the influence of gravity constantly pressed against the support rollers, and the shaft 27 of the cleaning mechanism - to the rims 14 and 15. In this case, Nfepe of wear of these rims and transmission wheels 33 and 34, the shaft 27 moves in the guides 31. If necessary, worn or plastic parts easily replace n are novel. In order to replace the cylinder 11, the valves 41 are opened and the longitudinal wall 40 is removed. The shaft 27 of the cleaning mechanism is removed from the guides 31 open at the top and taken out of the cavity of the housing 1. Slipping into the cylinder 11 above the support rollers and slightly moving it axially from the entrance 4, remove the cylinder 11 from the housing 1. Assembling the device with the installation of a new cylinder is carried out in reverse order. The technological process of calibration of seeds using the proposed devices for sorting bulk material can be carried out as follows. The starting product is fed to block 43 of the four calibration cylinders, where the largest fraction is collected, which is subjected to further processing as waste. The passage fraction of block 43 then goes to block 44, in which each calibration cylinder has two coarse and one fine fractions. The coarse fractions are fed to blocks 45 and 46, and the small separator 47. In the process of calibrating the material, the following small fractions are obtained in blockades 45 and 46 and separator 47, which are fed respectively to the trimers 48-50 for sorting by length. The target products are fed to the appropriate storage cells 51. The present invention provides a simplified installation and removal of the device, which reduces the time for its conversion when replacing the calibration cylinder or cleaning mechanism.
