Description

This invention relates to the field of agricultural engineering, in particular, to devices for separating and collecting leaves from cotton bushes.

The aim of the invention is to increase the efficiency of removal of leaves from bushes of plants.

FIG. 1 shows a diagram of a device for separating and collecting leaves from cotton bushes; in fig. 2, node I in FIG. one; in fig. 3 - node II in FIG. one.

A device for separating and collecting leaves from cotton bushes contains I working bodies installed in shells for separating leaves, made in the form of cylindrical perforated drums 2 having the same direction of rotation around

About vertical axes and placed with

; n the formation of a working gap for the passage

EO cotton bushes. With a gap of k: on the l surface of the drum 2 at the entrance of the barab: a passive knife 3 is installed in the casing for cutting unseparated leaves. A seal 5 is installed between the surface of each drum 2 and casing 1 at the point where the drum leaves the suction chamber 4 along its entire perforated surface. The device also contains storage bins (not shown), and casing 1 covers more than half of the perforated surface of drum 2,

The device works as follows.

Cotton bushes are crimped between two minimized gaps, which exclude damage to bushes and cotton bolls, rotate the spin in one direction and perform translational movement along the row by reels 2, They are located in suction chambers 4 so that their smaller part of the surface protrudes from the camera and forms a working suction surface. The branches of the compressed bushes move the rotating drums 2, each in the direction of rotation of one drum, and form a turn of the branches on the bush in the form of a fan between the drums 2 along the row, thereby increasing the slope of the surface of the compressed bush. In the internal volume of the drum 2, due to the suction of air through perforation of its surface into the suction chamber 4, vacuum is created, as a result of which suction leaves to the perforated surfaces. The leaves, sucked to the surface of the drum, move along with the drum and, detached from the branches, are carried away into the suction chamber, where they are sucked into the storage bins. The tops of the branches, due to their great flexibility, can often be dragged by the drum 2 into the suction chamber 4 and thereby clog up or jam the drums upon entering the chamber. In order to prevent this, when the drum 2 enters the chamber 4 along the entire perforated surface of the drum, a knife 3 is installed which also cuts from the branch of the unsealed sheet. To reduce suction, skidding the branch into the suction chamber, as well as to achieve a good cut.

between the surface of the drum and the cutting edge of the knife 3 is selected in 2-2.5 maximum sheet thickness. In order to reduce suction at the place where the drum emerges from the aspirations of the chamber and remove 2 leaves stuck in the perforations of the drum along the entire perforated surface of the drum, a sealant 5 is installed, which is also a scraper,

.

during the operation of the device, “Damage of branches, as well as suction and tearing of cotton bolls, is excluded, since they have a curved surface and can be sucked only to one hole, which is not enough to tear them off the branch.

Formula A. of gain

A device for separating and collecting leaves from cotton bushes, containing working bodies installed in the casing for separating leaves, including a knife, and suction nozzles arranged to form a working slot for the passage of cotton bushes, in order to improve the efficiency of leaves removal from plant bushes, working bodies for separating the leaves are made in the form of rotating in the same direction perforated drums with a vertical axis AXIS of rotation, the inner, cavity of which is connected to the suction point tube, each drum casing encompassed by more than half the circumference of the drum and the entrance into the housing is mounted a knife, while the output - a sealant.
