SU1246924A1 - Unit for harvesting long-stem farm crops - Google Patents

Description

The invention relates to agricultural machinery industry and can be used in the harvesting of various long-lived agricultural crops.

The purpose of the invention is to reduce the labor intensity of the subsequent folding of the harvested material folded in a stack and to increase the density of the stack due to its layer-by-layer formation of crushed and unground mass.

FIG. 1 schematically shows the proposed unit, a general view; in fig. 2 - part of pneumatic conveyor with deflector; in fig. 3 - feed conveyor, at the entrance to the pneumatic conveyor; in fig. 4 - shredder-beater.

The unit consists of a base machine 1, on which a pick-up 2 with a chopper 3 and a beater 4 are connected, connected by a pneumatic conveyor 5, at one end of which a fan 6 is mounted, and the other end is directed into a shaping chamber 7, and a deflector 8 is mounted on it change its position in the vertical plane. The conveyor 5 is divided into channels 9 by a partition 10. Between the chopper 3, the beater 4 and the pneumatic conveyor 5 a feed conveyor 11 is installed, also divided into channels 12.

The longitudinal partition 10 is located in a vertical plane, on one side of which the chopper 3 is installed, but the other beater 4, mounted on one horizontal shaft 13. At the exit of the pneumatic conveyor 5, the partition 10 has a curvilinear section connecting the vertical

the crown part of the partition with a horizontal one located in the deflector 8.

The unit works as follows.

Picker 2, located on base machine 1, picks up the swath and feeds it to the chopper 3 and the beater 4, where part of the roll is crushed and, together with the unmilled mass, is fed to the channels of the feed conveyor 11. This conveyor gives the crushed and unground masses separately to different channels 9 of the pneumatic conveyor 5 and transported by the air flow generated by the fan 6. At the exit of the pneumatic conveyor 5, the channels 9 are located one above the other. This makes it possible to stack the crushed and unmilled mass (when the position of the deflector 8 is changed up and down) sequentially layer by layer.

The use of the proposed unit reduces the connectivity of the material in the ounce, and increases its density due to the layering of the crushed and unmilled stalk mass. In addition, the use of the proposed unit will further increase the density of the material in the stack, since the crushed stem mass, as is well known, has a density of 1.5–2 times higher than unground, with all other conditions being equal. At the same time, alternately layer-by-layer stacking of crushed and unground homogeneous mass in stacks reduces the connectivity, i.e. efforts on rasskordovka steblesto, as the ground mass has a greater degree of flowability.

UNIT FOR CLEANING LONG-STEMED AGRICULTURAL CROPS, containing a base machine on which a cutting apparatus with a feed conveyor, a drum grinder with a horizontal axis of rotation, and also a pipe for removing the harvested mass are sequentially placed. characterized in that, in order to reduce the complexity of the subsequent scavenging of the harvested mass folded into the stack and increase the stack density due to its layer-by-layer formation from the crushed and unmilled mass, a beater is mounted on one shaft with a drum grinder, and the pipeline for removing the harvested mass is divided by a longitudinal partition, the end part of which adjacent to the drum grinder and the bit is located in the dividing plane perpendicular to the axis of rotation of the grinder and beater, and is smoothly interfaced with it its other end portion is located in a horizontal plane. 124692 Figure 1
