Abstract

The invention relates to forestry, in particular, to machines and mechanisms for reforestation. The aim of the invention is to improve the quality of landing. The receiving device is made in the form of an exhauster 2 connected at the entrance of the pneumatic line 3, which is provided at the outlet with a damper 4 and a guiding device 5 in the form of an inclined perforated stand with an adjustable stop 6. The guide device 5 is located between the cheeks of the coulter of the tree planting machine, and the pressure device made in the form of a centrifugal fan. In damper 4, the air flow expands and the flow velocity and pressure in it fall. When exiting the damper 4, the plants get into the guiding device 5 and further to the stops 6. 1 CW. f-ly, 2 ill.

The invention relates to forestry, in particular to machines and mechanisms for reforestation.

The purpose of the invention is to improve the quality of planting.

FIG. 1 shows a pneumatic landing machine, combined with a tree-planting machine, expose the view; in fig. 2 - the same, rear view.

The planting unit contains a centrifugal fan 1, a receiving exhauster 2, a pneumatic line 3, a damper 4, a guide device 5, an adjustable stop 6 for plants, a seat 7 of the planters, a cabin 8. The fan 1 of a centrifugal type, of medium pressure, is rotated - coming from the tractor's power shaft or hydraulic motor. Exhauster 2 is associated with a pneumatic line of constant cross section in the form of a flexible 3 having an injection pressure. The damper 4 is an expansion chamber in the form of a pipe with openings, the diameter of which is larger than the diameter of the air line.

The guide device 5 is a curved or obliquely mounted perforated stand. At one end, the device 5 is fastened to the damper 4, and the other is equipped with an abutment 6. The latter is made in the form of a fork of two plates located in the plane of the coulter of the tree-planting machine and centered on the landing furrow, mounted on the guide device 5 with the possibility of shifting in height in order to regulate the depth of embedding of the roots of planted plants. Cab 8 frame construction is designed to protect staff from weathering.

The landing gear works as follows.

When plants are introduced one by one into receiving exhauster 2, the latter sucks them into pneumatic line 3, where they are picked up by the air flow created by fan 1 and transported to damper 4. In the latter, the air flow expands, the pressure in it drops, and consequently decreases air flow velocity. Its effect on the transported plant weakens. When exiting the damper 4, the plants get into the guiding device 5, where they are slowed down, diminishing the speed of movement, and finally stop at the adjustable stop 6, which is set at a predetermined planting depth. The stop 6 is located in the deformation zone of the landing furrow by the press rollers of the tree planting machine. The roots of the plants are straightened on the anvil 6 by weakened air flow and are sealed in this position by the press rollers of the tree planting area.

Claims (2)

1. A landing machine of tree-planting machines containing a pneumatic line with receiving, pressure and damping plants, and a hollow opener, characterized in that, in order to improve the quality of landing, the damping speed of the device is made in the form of an air damper installed at the end of the pneumatic main and placed in the cavity of the collar, a perforated guide plate with an adjustable stop. 2. The apparatus according to claim 2, characterized in that the adjustable stop is made in the form of a fork of two beveled plates.
