Description

Seed Harvester

The device relates to agricultural machinery, in particular to machines for harvesting seeds, for example, beets.

A device for harvesting seeds, mainly beets, including a divider, a pressure fan, a pneumatic hammer and a container of seeds (as.with. No. 1232169, A 01 D 46/00). When the device moves along the rows, the air stream created by the blades of the pressure fan is fed to the stem of the testis, blows off the ripening seeds and transfers them to the container.

The device works without cutting the testes and allows you to collect the ripening and loosely attached seeds on the stem at the moment. Since the ripening of the seeds occurs unevenly, for the collection of the entire crop, operations have to be done repeatedly, which is neither efficient nor rational.

Currently, pshroko uses the technology of harvesting seeds, which involves cutting the testes with a reaper, laying them in a roll for drying, ripening and subsequent threshing. To raise the branches lying on the ground, the reapers are equipped with stalk lifters (Growing seeds of sugar beet hybrids on a CMS basis - recommendations, organizational and technological project of mechanized production of sugar beet seeds by the planting method M., 1985).

Known stem lifter for harvesting agricultural machines (a.s. No. 334946, A 01D 65/02), comprising a housing made in the form of a gutter

Rectangular cross section is used to collect the seeds reaping to the conveyor. Such stalk lifters should be installed in each aisle. When the reaper moves and the reel and knives interact with the stem, ripened and weakly fixed seeds that fall before the conveyor are collected in the gutters of the stem lifters. Mowed testes are placed in a roll for subsequent threshing. The disadvantages of this device include the fact that it allows loss of seeds between the bodies of the stem lifters. In addition, due to the small size of the hulls, periodic stops are required to remove the collected seeds.

To increase the efficiency of seed harvesting, it is proposed to equip the header with a device (Fig. 1), consisting of 2 lifters installed on the header 2, on which air ducts 3 are mounted, ending with nozzles 4 (Fig. 2) for air coming from fan 5. Behind the discharge window of the header 1 is installed capacity b with grate 7 and outlet conveyor 8.

The device operates as follows. When the header 1 moves along the rows and the reel and the cutting elements of the header interact with the testes, the most ripe seeds crumble and tend to fall onto the soil in front of the header. However, the air flow from the air inlet 3 through the nozzle 4 directs the seeds to the header canvases. Cut seed bushes and branches raised by stem lifters from the ground are fed here, then the crumbled seeds and bushes are conveyed by the conveyor to the unloading window of the header and to the tank 6. Passing over the tank 6, the roller descends to the soil to dry and ripen the seeds, and the selected seeds fall through the grate 7 and conveyor 8 are fed into the hopper of the combine.

The proposed device allows you to more fully collect mature and weakly attached to the stem seeds already in the process of cutting the testes.
