Figure 1 shows a machine for washing vegetable seeds; figure 2 - section A-L in figure 1; on fig.Z - section bb in figure 2; figure 4 - view 1 in figure 1 scraper chain conveyor).

The machine for washing vegetable seeds contains a cylindrical body 1, a shaft 2 located on its axis with a working body, a loading device 3, a mechanism 4 for removing: impurities, an inclined chain scraper conveyor 5 and a drive including a gear motor 6 a planetary gear two-stage horizontal and gear 7 with bevel gear Sfig.1).

The housing 1 consists of a washing chamber 8, in the lower part of which a reflector 9 and a funnel-shaped bottom 10 are installed with a branch pipe 11. The shaft 2 is installed in the bearings of the machine 12 and 13 and connected with a deaf coupling to the output shaft of the reducer 7. The housing of the lower bearing support shaft 2 is mounted on a cross plate attached to the bottom 10 of housing 1. A screw 14 of a blade 15 is mounted on shaft 2, a crosspiece 16 with blades 17, a disk 18. The blades 15 are fixed at an angle to the axis of the shaft 2 to create axial flows of water, seed impurities that contribute to the immersion they are in the washing chamber 8. On the shaft 2, the crosspiece 16 is also fixed with rollers 19, which come into contact with the projections 20 of the disk 18. The crosspiece 16 is fixed, and the disk 18 is mounted with a clearance on the shaft 2. To the cover of the bearing support housing 13, are fixed cylindrical fingers 21, placed with a gap in the holes of the disk 18. between the cover of the bearing support body 13 and the disk 18 is installed spring 22.

The loading device 3 contains a hopper 23, a flap 24, a funnel 25, the tube 26 is fixed to a smaller diameter. The funnel 25 is fixed to the cover of the cylindrical body. The screw 14 is installed in the funnel 25, the blades 15 are placed in the pipe 26.

Mechanism 4 for removing impurities includes perforated scrapers 27, which are fixed by means of hinged suspensions 28 to rotating beams.

30, in the upper part of which a ring 31 is welded with three cross-arms 29. In the washing chamber 8, a bath 32 with an apertured partition 33 and a branch pipe 34 is attached to the cylindrical body 1. An arc-shaped rod 35 is mounted above the bath 32.

the washing chamber 8 and the side wall of the bath 32 adjoin the perforated sector plate 36 mounted at an angle to the horizontal flatness of FIGS. 2 and 3 /.

A pipe 37 is connected to the bottom of the bath 32 for draining water, obtained by dehydrating impurities on a perforated partition 33. The inclined chain scraper conveyor 5 consists of a housing 38, a tray 39 with a pipeline 40 and a valve 41, and a branch pipe 4 (FIG. 1). The drive in rotation of the sprocket 43 is carried out from the motor-reducer 44 of the planetary gear two-stage horizontal. Attached to the stub-roller chain 45 strap 46 and. elastic perforated skr.bki 47 (figure 4). To supply water to

-washing chamber 8 serves as a float device consisting of a bath 48, a float 49 and a valve 50. A float device is connected to a pipe 51 for supplying water to the washing chamber 8 (Fig. 1}. The bath 48 of a float device is connected by a pipe 52 with a reflector , 9, which is provided with windows 5-3 for the exit of water.

The machine works as follows.

Water is supplied to the washing chamber 8 of the housing 1, the level of which is maintained by a constant float device. From the bunker 23. The seeds, along with impurities, continuously flow into the funnel 25. When the shaft rotates, 2 auger 14 feeds the seeds along with the impurities into the tube 26. The rotating blades 15 create axial flows of water, seeds and impurities that promote immersion.

seed into the washing chamber .8. After exiting the tube 26, the seeds and impurities are subjected to the impact of water. The impact of water on seeds and impurities is produced by means of a disk 18 vibrating in the vertical plane. The oscillatory movement of the disk 18 is due to the movement of the rollers 19 of the cross 16 along the projections 20.

Spring 22 provides constant contact between rollers 19 and protrusions

20 during rotation of the shaft 2 (FIG. 1). The mixture of seeds with water in the chamber 8 receives a circular motion due to the rotation of the blades 17. The separation of seeds and

impurities are produced due to the difference in their densities. Defective seeds, mucus and various light impurities are entrained by the flow of water to the upper part of the washing chamber 8 and diverted

perforated scrapers 27 into the bath 32. When the ring 31 rotates, a circular movement of the cross member 29 with the perforated scrapers 27 (figure 2) is obtained; light impurities are removed by the scrapers

27 to an inclined perforated plate 36, through the holes of which water flows back into chamber 8 (FIG. 3. Further movement of the plate 27 leads to the entry of impurities into the wa: 32 and then they are discharged from the mash. Through the nozzle 34. When impurities fall on the perforated surface baffles 33, additional impurity dehydration occurs (). Water that collects at the bottom of bath 32 due to mechanical dehydration of impurities is removed from the machine through pipe 37. Seeds settle at the bottom of the bottom 10 and gradually go through pipe 11 to the conveyor 5. The seeds are moved by rubberized perforated scrapers -47 of the chain conveyor 5 to the nozzle 42 (Fig. 1) and discharged from the machine through it. Reflector 9 contributes to the formation of an upward flow of water as well as the impact of water on it due to vibration the disk is. During the sanitization of the machine, water with various contaminants is discharged to the treatment plant through the pipe 40 at the preliminary opening of the valve 41.

Improving the quality of washing the seeds of vegetable crops is achieved by installing a pipe 26 crosses 16 with blades 17 and a disk 18 vibrating in the vertical plane on the shaft 2 in the outlet branch pipe. The impact of the Vrda on seeds and impurities due to the vibration of the disk-18 promotes separation mucus and also accelerates the flotation process. Intensive mixing of seeds with water through the use of these two technical solutions helps to increase machine productivity.

The implementation of the loading device 3 with the funnel 25, in the zone of which the rotating auger 14 and the blades 15 are installed, helps to obtain horse-washed and intact seeds.

Providing a mechanism 4 for separating impurities with perforated scrapers 27 and a perforated sector plate 36, as well as a bath 32 with a perforated partition 33, promotes the mechanical dewatering of the Impurities during their removal from the washing chamber B.

In addition, this solution provides a reduction in water consumption by returning the latter to the washing chamber 8 after cleaning from impurities. Performance of chain spreaders. The perforated conveyor belt also contributes to the reduction of water consumption when washing the seeds of vegetable crops.

The annual economic effect from the introduction of one machine in the seed farms of agriculture in the production of seed, as well as in canneries for washing seeds of tomatoes and sweet peppers for the purpose of their utilization is 5,860 rubles.
