EP0211907A1 - Radial harvester-gin for cereals and similar products - Google Patents

Abstract

The slow friction continuous ginning process is made up of two essential sets: 1) one or more cylindrical ginners (5) fitted with rib profiles (12), the profiles are different for certain crops. 2) one or more inert counter-ginners (6) page A or activated (figure on page C (6)). The ginner assembly (5) + (6) is of approximate width of the cut (2) and is placed behind the latter (2) and in front of the straw beater (7) and the ejector (8). The worm (10) collects the impure grain and transmits it to the separator (11). This is located above the organs described and transfers the grain harvested by the screw (15) into the accompanying tank.

Description

Radial grain harvester and similar products.

The present invention relates to a harvester with a radial ginner by friction. The threshing is currently done by shock. Drummers generally consist of two separate sets.

One or more fast-moving beaters and spaced bats. One or more concave with openwork, inert, adjustable and +/- enveloping edges. The machines are equipped with one or more longitudinal or transverse beaters.

A beater is an assembly made up of an axis on which are fixed several discs which maintain spaced and ribbed bats, the width of the assemblies varying between 1/2 and. 1/4 of the cutting width. The threshing by shock effect currently known, has multiple drawbacks, the rapid movement of the thresher requires a lot of energy, the threshing is imperfect many ears separate from the stem and arrive at the separation without being beaten and must be again introduced to the batter for a new circuit; it is easy to understand that such a process makes these machines heavy, bulky, complicated. They feed irregularly in the harvested crops and further damage the straw.

Our new harvesting process is on the contrary light, space-saving, simple, regular feeding, moreover it respects the straw and saves energy.

By its advantages, it can be placed in front of a tractor which pushes it and activates it and pulls or carries a tank; the assembly very advantageously replaces a self-propelled combine. The purpose of this invention is to recover the tractor, the most expensive part of the whole for other crops and work.

Our new ginning process works by continuous friction. It is made up of sets that we call the ginner (5) and the counter-ginner (6). The ginning part consists of one or more externally ribbed cylinders (12), that is to say placed transversely to the displacement of the assembly (see arrow) with slow movement and of width approximately similar to that of the cup. The divider (1) separating the rods from each pass. The counterregenerator which envelops part of the ginner, is inert and adjustable (6) page A and composed of openwork edges allowing the passage of impure grain (grains + flakes). It can also be actuated, it consists of one or more rollers formed of one or more elements enveloping the ginner and rotating in opposite directions and at a different circumferential speed so as to create friction between the ginner and the counter ginner. The stem and the ear pinched between these organs are thus ginned (6) page C. The ginner assembly is located directly behind the cut (2) hence the regular feed, constant material flow.

The stem and the ginned ear emerging from the ginner are driven by one or more straw-pullers (7) towards the ejector

(8) and are covered in one or more trains (16) along the cutting width.

The movement of straw in contact with the straw beater and the ejector promotes the recovery of the last grains which have escaped the counter-ginner and are recovered through the perforated grid (9).

The impure grain is collected by the screw (10) and directs to the separator (11) which removes the impurities (object of a other deposit) at the exit of this one, the pure grain is collected in the screw (15) and conveyed towards the accompanying hopper which can be pulled, carried or semi-carried by the tractor which actuates and pushes the machine. Of course various modifications can be made by those skilled in the art to the machine which has just been described solely by way of non-limiting example, without departing from the scope of the invention.

The movements are indicated by arrow.

Claims

claims

1. Harvesting machine which has one or more ginners (5) at slow speed and of width substantially equal to that of the cut (2).

2. Combine and ginning machine described in 1 in which the counterweighting device (s) (6) the straw puller (s) (7) the ejector (s) (8) are of approximate width of the cutting member (2).

3. Machine described in 1 and 2 with one or more ginners which are wrapped in a certain sector by one or more inert and adjustable counter-ginners page A (6).

4. Machine claimed in 1 and 2 with one or more ginners wrapped over part of their circumference by one or more counter-ginner assemblies page C (6). The counter-ginner turns in the opposite direction to the ginner, at a +/- different circumferential speed and these are mounted coaxially between them.
