Abstract

The invention allows, by eliminating crushing of the stems, to more fully collect the non-grain part of the crop. The device contains a feed drum 1, a stripping conveyor 2 with teeth 3 and a collection chamber 6. Parts of the teeth 10 of the combing device located in front of the wheels of the unit are made with pointed edges. The method of cleaning includes stripping the apical part of the plant, followed by stubble mowing. Tooth 10 cut stalks in a rut. 2c and 1pc files, 2 ill.

The invention relates to agriculture and can be used in the harvesting of cereals, leguminous crops, grass seed plants.

The purpose of the invention is a more complete harvesting of the non-cereal part by separate harvesting of the apex collar and non-cereal parts of the crop by eliminating the pruning of the stems.

The method is carried out as follows. The combing adapter's toothed tooth is combed by the stem, the top of the plant is broken. The adapter teeth located on the path of the wheels of the machine, having pointed edges, cut off the stems in a rut, so that the wheels move along the already sloping low stubble. The straw, together with the combed heads, goes to the threshing machine of the combine or to the replaceable tractor trailer, after which it is threshed in the combine or at the hospital and stored. After drying on the vine, the remaining tall stubble is mown with a header with loading into a trailer or pressing, and the movement of the aggregate in the direction opposite to the direction of movement of the combing adapter or perpendicular to it, ensures that the stems are completely mowed.

FIG. 1 is a schematic of a stripper for carrying out the proposed method; in fig. 2 shows section A-A in FIG. one.

The device consists of a feed drum 1, a scrubbing conveyor 2 with teeth 3, a movable 4 and a fixed 5 covers, an assembly chamber 6 with a screw 7 and an inclined chamber 8. The scrubbing tooth of the conveyor is made in the form of a comb composed of separate sections. The comb includes sections with a combing 9 and sharpened 10 teeth, in which segments of the cutting apparatus of the header are used. The width B of sections 10 is equal to the width of wheels 11, and the distance K between these sections is the width of the track of the harvesting machine. In this case, the number of driving, controlled, wheels of the harvesting machine and the wheel of the trailer wheels (if the device is involved in cleaning with mass treatment at the hospital) is equal and the sections with pointed teeth 10 describe in a longitudinal direction the trajectory that coincides with the path of the driving wheels of the harvesting machine.

The application of the proposed method and device will reduce the loss of the non-cereal part of the crop.

Claims (3)

Claim 1 A method of harvesting grain crops, including stripping the apex part of a plant with subsequent cutting of stubble, characterized in that, in order to more completely harvest the non-grain part of the crop by eliminating the sting of the stems, the latter, located in the path of movement of the wheels of the unit, mow and clean simultaneously with the apical part. 2. The method according to claim 1, wherein that the remaining stubble is mowed in the opposite direction or perpendicular to the stripping direction. 3. A grain harvesting device comprising a frame with wheels, a feeding device, a puller with teeth and a collecting chamber, characterized in that the teeth of the scrubbing machine located in front of the wheels are made with pointed edges. 1
