Description

The utility model relates to agricultural machinery, in particular to dispensers of bulk materials.

Known metering system developed by NPO VISKHOM, containing a chamber for seeds, a coil for sowing seeds, upper and lower thresholds (N.V. Lyubushko, Yu.M. Krivoshey. Combined sowing device of a pneumatic grain-seeder., Wl "Tractors and agricultural machinery ”, 1989, No. 12.

A dispenser for bulk materials is also known, comprising a seed chamber, a lid, a coil for sowing seeds mounted on the drive shaft, upper and lower seals, an air chamber (Copyright certificate SU 1729317, IPC A01C 7/12, published on April 30, 1992).

The disadvantage of these designs is that they do not provide for the possibility of adjustable emptying of the chamber for seeds from the remaining seed. If necessary, empty the chamber for seeds, remove the lid of the dispenser, the bulk material remaining in the chamber immediately spills onto the canopy, after which it is manually collected in containers (bags). Moreover, the complexity and low productivity are obvious and, in addition, the loss of seed is inevitable.

The technical result of the utility model is to reduce the complexity and losses of the unloaded seed residue when emptying the seed chamber.

The specified technical result is achieved by the fact that in the dispenser of bulk materials containing a chamber for seeds, a cover, a coil for sowing seeds mounted on the drive shaft, upper and lower seals, an air chamber, according to the claimed technical solution, the dispenser cover is made in the form of rigidly interconnected along the perimeter of the front and rear plates located with a gap relative to each other, in which a slide gate valve is installed with the possibility of longitudinal movement in the gap between the plates, in addition, the cover has a discharge window with a guide pipe and on the front plate of the cover there is a longitudinal slit hole for the handle of the slide gate valve, and a lower seal is fixed on the rear plate.

The essence of the technical solution is illustrated by the drawing, where

- in FIG. 1 is a diagram of a dispenser;

- in FIG. 2 - dispenser cover in a perspective view;

- in FIG. 3 - dispenser cover (side view).

The dispenser of bulk materials contains a chamber for seeds 1, equipped with a cover 2, a coil for sowing seeds 4 mounted on the drive shaft 3, an upper 5 and a lower 6 seals, an air chamber 7. The cover 2 of the dispenser is made in the form of front 8 and rear 9 rigidly interconnected plates located with a gap relative to each other. An unloading window 10 is made in the lid 2 with a guide pipe 11 mounted on the front plate 8 of the lid to direct the flow of bulk material when emptying the chamber 1. Between the front 8 and rear 9 plates there is a slide gate valve 12 with a handle 13, which prevents unauthorized emptying cameras 1 in the closed position is fixed by thumb screws 14. In addition, on the front plate 8 of the cover there is a longitudinal slit hole 15 for the handle 13 of the slide gate valve 12 and two handles 16 for convenience installing cover 2 at the regular place of the dispenser.

The dispenser works as follows.

Installed on the drive shaft 3, a coil for sowing seeds 4, rotating, captures the seeds that enter the chamber 1 from the hopper (not shown). Seeds captured by the grooves of the coil 4 are ejected through the lower seal 6 into the air chamber 7, where they are picked up by the air flow and fed to the divider (not shown).

The upper seal 5 together with the coil 4 prevents the spillage of seeds from the chamber 1 into the air chamber 7. Emptying the chamber 1 from the remaining seed is carried out as follows.

In the lid 2 of the dispenser, after loosening the thumb screws 14, using the handle 13 open the slide gate valve 12. Then, through the discharge window 10 along the guide pipe 11, the bulk material will begin to pour out of the chamber 1 directly into the prepared container (bags). If it is necessary to stop the process of emptying the chamber 1 after filling the next container, it is necessary to block the discharge window 10 with the slide gate valve 12.

The utility model provides controlled emptying of the chamber for seeds, which significantly reduces the complexity and loss of seed material during its unloading.
