Description

The invention relates to forestry and is intended for mechanized processing of conifer forest seeds before sowing.

The aim of the invention is to increase the productivity by increasing the degree of preliminary screening of seeds.

Fig. 1 is a schematic representation of a machine for seaming seeds, a general view; in Fig. 2, section A-A in Fig. one; Fig. 3 shows cylindrical guides, axonometrics.

The machine for cutting forest seeds includes a cylindrical body 1, in the form of a drum with a mesh or combined working surface (the upper part is made of rubberized material, and the lower part is a mesh bottom). Inside the housing 1, a shaft 2 is installed, on which elements for separating the wings of seeds, made in the form of brushes 3, are fixed. They are located along a multiple, in particular four-way, helix and are installed at an acute angle towards each other in adjacent turns, overlapping in turns another one. Above the cylindrical body 1 there is a loading hopper 4 with auger brush feeder 5. In the hopper 4 cylindrical guides 6 and 7 are installed. The surface of the guides is made tubercular. The left 6 and right 7 guides in their lower parts are provided with horizontal axes 8, with respect to which they can rotate.

Axes 8 can be made in the form of screws screwed into special brackets fixed on halves 6 and 7, or axis 8 can be made in the form of a rod rigidly fixed on each half of a split half cylinder.

To change the position of the guides B and 7 relative to the screw 5, cutouts 9 a are provided in the walls of the hopper 4 for fixing them in a certain

position there are thumb screws 10 installed in special threaded holes of the brackets 11. Such a constructive solution allows for quick assembly and disassembly, as well as

very quickly and without stopping the machine to make the appropriate adjustment.

The guides 6 and 7 are installed in such a way that a gap is formed between them for the passage of the seeds to be processed into the cylindrical case 1. The size of the slit, and accordingly, the amount of seed supplied from the feed hopper 4 to the case 1, can be adjusted by a gate 12.

To the upper parts of guides b and 7

pitched shelves 13 are attached, which are in contact with the flaps 14. The flaps 14 are attached to the walls of the bunker 4 hinged and spring-loaded. It is necessary for

when changing the position of the cylindrical guides 6 and 7 of the flange 13 and the flap 14, there is, as it were, a single plane along which the seeds freely enter the screw 5 (the flap always assumes the position corresponding to the flange position) through which the untreated seeds could get on the back side of the guides 6 and 7 and for 5 enter into the housing 1. From above, the hopper 4 is covered with a lid 15. The machine works as follows Seeds fall asleep into the hopper 4. When Crop auger pitteln 5

0 they are picked up by them and carried away in traffic. When the seeds interact with the auger feeder 5 and the lumpy surface of the guides b and 7, the winged cells are partially separated from the seeds and their

feed through the slit into the housing 1 Due to the fact that the guides 6 and 7 are installed with the possibility of their rotation around the horizontal axis 8, it is possible to increase or decrease the gap between their surface and the screw 5 and thereby regulate the process of preliminary blanketing of seeds ; hopper. Hit the cylindrical body

1, the seeds are finally separated from the caps and the passage through its mesh surface into the collection receiver. Large seeds and impurities that accumulate in the corus. periodically removed through a special flux (not shown). For seeds that have a small amount of force associated with the seeds and a small flowability (pine and spruce, C, etc.), the gap at the entrance can be made larger, and at the exit - smaller, in order to involve more mass of seeds and faster to separate the lionfish. For seeds that have a significant force of communication between the lionfish and seeds, a large bulk mass (larch, canopy, acacia, etc.), the gaps need to be set small so that the brush elements take up a mass of seeds equal to or slightly larger than feed into the drum for a given performance. In this case, the force of friction of the seeds between the grooved surface of the walls and the brushes increases.

and the seeds, with a small feed for one revolution of the feeder shaft, maximize the aging of the stock. In addition, when processing certain types of fruit-beans (common glaciers, plots, etc.), it becomes necessary to make the input part wider to capture the pods, and to cover the output part somewhat.
