Description

(54) APPARATUS FOR SEPARATION OF LEAVES

one

The invention relates to agricultural machinery, in particular to machines for the mechanical removal of leaves in fruit nurseries, on tobacco plantations, etc.

A device for removing leaves 5 and young shoots from stalks of agricultural crops is known, which contains a clamping conveyor and a leaf-separating mechanism with a drive made at an angle to the clamping conveyor, about thera and forming a working slot of two rotors with flexible metal scourges fixed on them 1 .

A device for separating leaves is also known, which contains fixed on the frame and connected to the drive mechanism a column-mounted drums with flexible elements 2 arranged on them along a helical line.

A disadvantage of the known devices is injury to the bark and the kidneys of the plants.

The purpose of the invention is to reduce injuries of the cortex and kidneys.

This goal is achieved by the fact that the flexible elements are made in the form of f-shaped loops installed with a preliminary twisting tension and at an angle to the axis of rotation of the drum equal to the angle of inclination of the latter to the horizon. And also by the fact that the screw line of the hinge on the drum is made with variable pitch, decreasing to its upper part.

FIG. 1 shows the proposed apparatus, a general view; in fig. 2 - the same, front view; in fig. 3 is a view along arrow A in FIG. 2; in fig. 4 is a view along arrow B in FIG. 3; in fig. 5 is a sectional view BB in FIG. four.

The apparatus contains fixed on the frame 1 and connected to the drive mechanism 2 obliquely installed drums 3 with flexible elements made in the form of jf-shaped loops 4 installed with preliminary twisting tension and at an angle to the axis of rotation of the drum 3 equal to the angle of inclination of the latter to horizon.

Claims (2)

The screw line of the hinges 4 on the drum 3 is made in variable pitch, decreasing to its upper part. The drums 3 are made with L-shaped ribs 5 having conical holes 6, in which brackets 9 are installed with conical shanks 7 and nuts 8. Loops 4 are attached to brackets 9 with screws 10 and clamping strips 11. The device works as follows. The drive mechanism 2 is activated, which informs the drums 3 of counter-rotation and movement of the clamping conveyor (not shown). When the apparatus moves along a row of plants, loops 4 tear off the leaves along the entire height of the plant from top to bottom and drop them to the ground. The apparatus allows reducing injuries to the bark and kidneys of plants and increasing labor productivity. Claims. The apparatus for separating leaves, which are fixed on the frame and connected to the drive mechanism obliquely // //// $;% 5c // $ 2 Q} L / S.1 Figs. drums with flexible elements disposed on them along a helical line, characterized by 7, which, in order to reduce injuries to the cortex and kidneys, the flexible elements are made in the form of y-shaped loops installed with a preliminary twisting tension and at an angle to the axis of rotation drum equal to the angle of inclination of the latter to the horizon. 2. An apparatus according to claim 1, characterized in that the screw of the loop positioning line on the drum is made with a variable pitch, decreasing to its upper part.
