RU2324322C2 - Pototato combine - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: pototato combine consists of digging under tool, basic elevator, clod smashers, additional elevator, sparse rod carrier vehicle, elevating drum, unloading carrier vehicle and loading pocket for tubers. The digging under tool consists of the active share and the paired disks with an active disk knife and the disk lift attendant. The combine in addition contains forked guide, on rod of which the rubber (or from other elastic materials) tubes are put on or scrubbers are installed and fixed on the top. The bristle of scrubbers can be executed from various materials, and the bristle slope can be adjusted.

EFFECT: decreasing of potato tubers damaging at harvesting by a combine.

Description

The machine belongs to the field of agricultural engineering, in particular to machines designed for digging potatoes on ridge and half-ridge plantings with rows of 70, 75 and 95 cm, separating tubers from soil, tops and vegetable impurities, followed by collecting tubers in a hopper and unloading them into a transport means. This combine is designed for harvesting potatoes from small-contour fields of farms, breeding centers, farms engaged in potato seed growing in all favorable zones, except for areas of mountain farming.

Closest to the proposed harvester by the method of operation and the achieved effect is a potato harvester, a schematic diagram of which is presented in figure 1 (see RU, RF Patent No. 2210881, CL A01D 17/00, bull. No. 24, 2003).

A disadvantage of the known design is that potato tubers are damaged due to the presence of a coarse-grained structure of the soil formation on the main elevator and on the delta from the clod drive to three forked guides 4 pivotally mounted and spring-loaded from the bottom (made in form of inclined rods gutters.

The purpose of the invention is the reduction of damage to potato tubers during harvesting.

This goal is achieved by the fact that instead of a simple share, a working body consisting of an active share is used instead of a simple share, which is supplemented by the installation of paired disks with an active disk knife and disk elevator 13, which allows better grinding of the soil layer, and this, in turn, , reduces damage to potato tubers. In addition, rubber (or from other elastic materials) tubes are put on top of the fork rail or brushes are installed and fixed on top, the bristles of which can be made of various materials, and the angle of inclination of the bristles can be adjusted (for example, the angle of inclination at 30 ° (in beginning) or 60 ° (at the end of the guide) in the direction of movement of the tubers).

The proposed design of the potato harvester consists of a digging body 1, a main elevator 2, clump 3, a fork 4, an additional elevator 5, a lifting drum 6, a rare-wire conveyor 7, a top-cutter 8, a collision bar 9, an external conveyor 10, a loading conveyor 11, the hopper for potatoes 12, paired disks with an active disk knife and disk elevator 13 (Figure 1).

Figure 2 shows the difference in potato tuber after lumps on the bar fork fork in the section.

So, the combine works as follows: the soil layer dug up by a digging body is fed to the main elevator, where it is sifted down, and the lumps of soil and tubers 2 with the remains of tops and stolons go to the co-cutters 1. After the co-cutters 1 tubers 2 with the remains of soil, tops and the stolons fall onto the rods 3 of the fork rail, where they first hit the bristles of the brushes 4, and then roll down it.

Thus, the kinetic energy of potato tubers is suppressed by deformation of the bristles, which are directed at different angles (at the beginning of the bar 30 °, and at the end - 60 °) and, therefore, they are less damaged.

Then the tubers arrive at the lowest possible speed (which also provides damage reduction) into the interior of the harvester lifting drum.

Claims (1)

A potato harvester containing a digging tool, a main elevator, clutch drivers, an additional elevator, a rare-wire conveyor, a lifting drum, an unloading conveyor and a tuber hopper, characterized in that the digging tool consists of an active share and paired disks with an active disk knife and disk elevator wherein the harvester additionally contains a forked guide, on the rods of which rubber (or from other elastic materials) tubes are put on top or mounted on top ayutsya and fixed brush bristles which can be made of different materials and bristle inclination angle can be adjusted.
