SU128680A1 - Combine for cutting corn stalks, separating and cleaning the cobs and chopping the leafy mass - Google Patents

Description

The disadvantage of currently used combine harvesters for harvesting corn is that they lack a reliable working body for cleaning cobs.

The proposed harvester is distinguished by the fact that cuts are made against the working slots of the rollers for the passage of wrapping leaves unsealed from the cobs, and the outgoing ends of the rollers have a conical shape with a spiral protrusion of constant or irregular height.

This achieves the elimination of the clogging of the cob and provides for the release of the wrapped leaves squeezed between the rollers, but unwrapped from the cobs, and moving them outside the cob leaves.

FIG. 1 schematically shows a combine, side view; in fig. 2 - the same plan view; in fig. 3 is a schematic of an exciting mechanism; in fig. 4 - cob rollers.

The combine consists of the guide mechanism /, the pickup rollers 2, the gripping mechanism 5, the conveyor 4 cobs, the feed rollers 5 with the guide tray 6, the knife drum L of the cutting unit 8, the pitched tray 9, the cobs 10 with conveyor 11, the conveyor 12 cleaned cobs , conveyor J3 of crushed silage, cob pipe 14 with valve 15 and valve 16.

The guide mechanism 1 consists of two endless flexible bands (chains, belts) with tabs on the surface to prevent the stems from slipping. The purpose of the mechanism is to seize and direct those corn stalks that are not opposed to it for some reason to the patching machine. front surfaces, the working surfaces of the steering mechanism move at an acute angle to each other, and then parallel and plant stems in work No. 128680

These fingers are designed to pick up the stems located away from The stem of the mechanism. The stalk clamped by the slats 20 is cut by the cutting apparatus 8 and moves along the channel 24 to the feed rollers 5.

A guide tray 6 is installed near the lower ends of the threading rollers, the working surface of which is placed at an angle to the direction of movement of the working branch of mechanism 3. This tray aligns the combs of the stems, reduces the length of their ends below the working branch of the mechanism, which improves the conditions for feeding the stems to the knife drum .

Above the upper ends of the feed rollers is mounted a visor 25, intended for bending down the vertical stems. The knife drum 7, which interacts with the shearing plate 26, crushes the stems and leaves and dumps them onto the conveyor 13, from where the ground mass enters the vehicles.

The cobs, separated from the stems, fall on a chain-lined conveyor 4, and then on pitched trays 9, divided into longitudinal streams, along which ripe ears go down to the cob

The cobs of milky-wax and wax ripeness are directed through the hatch, covered by the valve 15, through the pipeline 14 to the receiving chamber of the knife drum, covered by the valve J6.

In the rear wall 27 of the roller anchorage, against the working target, slots 28 are made for the passage of the wrapped leaves, which are not torn from the cobs. In addition, in order to ease the squeezing of these leaves by the rollers, their ends at the gathering of the cobs have a conical shape with a spiral protrusion 29 of constant or variable height, due to which the wrapping leaves move beyond the limits of the cob cleaner through the working slot.

The cleaned cobs descend from the pick-up rollers and conveyor 12 into a trailer cart. The grain that was exfoliated on the cob falls on a chain-lamellar conveyor 11, the flooring of which under the upper branch is made of a grating with round holes with a diameter greater than the grain size of the corn. Corn grains fall through these holes and fall onto a sieve installed under the lower branch of the conveyor 11, the slats of which shift 1 {xg grain into the receiving chamber of the conveyor 12, and the latter moves the grain together with the nightstands into the trailer cart. The wrapping leaves of the cobs are dropped to the ground by the upper branch of the conveyor //.

Claims (3)

1. A harvester for cutting corn stalks, separating and cleaning the cobs, and chopping the leafy mass, different in that, in order to eliminate clogging of the night cleaner, freeing sandwiched between the rolls, but not wrapped from the cobs, wrapped around the cob leaves, opposite the working slots of the rolls, slots are made for the passage of wrapping leaves that are not cut off from the cobs, and the outgoing ends of the rollers have a conical shape with a helical protrusion of constant or variable height. 2. A combine according to Claim 1, characterized in that, in order to ensure reliable gripping and guiding the stems into the working streams, it incorporates a gripping mechanism with straight or shaped fingers attached to the sprocket disks. 3. A combine according to claim 1, characterized in that, in order to facilitate the introduction of the stems after the release of the cobs into the working channel, the latter is placed in the same vertical plane with the working stream of the picking apparatus and is its continuation. - 3 128680
