Description

The utility model relates to crop production, in particular to cassettes for growing seedlings of trees, shrubs, etc. with a closed root system.

A container for growing seedlings is known, containing a frame having a plurality of legs, in which a container for growing seedlings is located. The upper part of the container protrudes outward in the radial direction, the lower part is made cone-shaped and formed at different angles relative to the center of the lower surface without radial overlap. On the lower part there are two rows of slots, and one row is offset relative to the other so as not to overlap each other. On the top plate of the frame part, a section protruding outward in the horizontal direction is formed. Ribs are provided on the inner peripheral surface of the conical part (patent No. JP2020195361, IPC A01G9/00, publ. 12/10/2020).

Known cassette for growing seedlings, which is a container made of impact-resistant frost-resistant plastic, in the form of a rectangular cassette containing a platform with cells of a square shape with beveled corners in the plan in the upper and lower planes, tapering downward, and made a hole in the lower plane of each cell, the walls of which are interconnected by stiffening ribs and have vertical slots to a height of two-thirds of the height of the cell wall, in the ribs separating the cells in the upper part, slotted slots are made 10 mm high from the upper edge and 2 mm wide (patent No. 2553645, IPC A01G 9 /00, published 06/20/2015).

The closest set of essential features is a cassette for growing seedlings, containing combined by a clip and connected to each other in the upper part of the cell with a square section tapering to the bottom, and with a hole in the bottom part, the walls of the cells have vertical ribs on the inner surface and vertical slots , the walls of the cells are connected by means of horizontal and vertical jumpers, and the vertical slots are made intermittent, while the cells are made with rounded corners (patent No. 184914, IPC A01G 9/00, publ. 11/14/2018).

The disadvantage of these technical solutions is the insufficient rigidity of the cell, and the cassette as a whole. the slots made on the conical part of the cells significantly weaken the cell and make it more brittle.

The technical problem is to increase the rigidity of the cell cassette, thereby increasing its service life.

The technical result coincides with the specified technical problem and is achieved by the fact that in a seedling cassette containing a combined cage and connected to each other in the upper part of the cell, tapering to the bottom and with a hole in the bottom part, the walls of the cells have vertical ribs on the inner surface and vertical slots, the cells are connected to each other in the upper part by means of vertical bridges and are made with alternating wide and narrow walls tapering downwards, forming an octagon in plan, while the thickness of the wide wall in the lower part is greater than 10-15% than in the upper part, and the vertical slots are made solid and located on the thickened part of the wide walls, and the vertical ribs are made on the inner surface of the wide and narrow walls.

The bottom part of the cell of the forest seedling cassette is made with intersecting bridges connecting the side walls of the cell, or the bottom part of the cell can be made with a ring connected by bridges to the side walls of the cell.

New features are the execution of a cell with alternating wide and narrow walls tapering downwards, forming an octagon in plan, while the thickness of the wide wall in the lower part is 10-15% greater than in the upper one, while the vertical slots are made solid and located on the thickened part wide walls, and vertical ribs are made on the inner surface of wide and narrow walls. Dividing the cell walls into narrow and wide ones, as well as making a wide wall with an increased thickness in the area of vertical slots, and making a rib on the inner surface of wide and narrow walls can significantly increase the rigidity of the cassette, which prolongs its service life.

Dependent item is also aimed at achieving the specified technical result.

The utility model is illustrated by drawings:

Fig.4 - view A in Fig.3.

The forest seedling cassette is made of high-strength composite material. Working with solid cassettes can be easily mechanized and automated. For example, the supply of cassettes to the filling and sowing line, the pushing of seedlings from the cells and their packaging can be done mechanized.

The cassette contains a plurality of cells 1 connected to each other in the upper part. The cells 1 are united by a holder 2, which slightly extends outward from the cells 1. This allows the cassettes to be stacked in a stack. At the corners of the cage 2, grooves 3 are made, which facilitate the release of adjacent stacked cassettes from the stack.

Cells 1 are made tapering to the bottom with a hole in the bottom.

Cells 1 are made with alternating wide narrow walls tapering downwards (4.5), forming an octagon in plan. The thickness of the wide walls 4 increases towards the bottom by about 10-15%. On the thickened part of the walls 4, vertical slots 6 are made. The increased wall thickness in the area where the slots 6 are located makes it possible to increase their number. In a specific case, there are three of them on each wide wall 4. Slots 6 prevent the formation of a lack of oxygen in the peat lump in the cell and at the same time act as a drainage in case of excessive watering.

Walls 4 and 5 of cells 1 have vertical ribs 7 on the inner surface, and on wide walls 4, ribs 7 are located between slots 6. Cells 1 and cage 2 are connected to each other by means of vertical bridges 8. Vertical bridges 8 are evenly distributed along the perimeter of cells 2. In the connected state, the upper edges of the narrow walls 5 of neighboring cells 1 form a rectangle.

The hole in the bottom part of the cell 1 is made with intersecting bridges 9 connecting the side walls of the cell. The bottom of the cell 1 can be made with a ring 10, which is connected by means of jumpers 9 to the side walls of the cell 1. Excess irrigation water easily flows out of the bottom hole. Thanks to the open bottom of cell 1, watering is also possible from below. In this case, the cassette is provided with a tray.

The inner surface of cells 1 has a glossy surface, which greatly facilitates the removal of seedlings from cells 1. Cells can be made in different heights for growing different seedlings.

Vertical slots 6 and guide ribs 7 in the walls of cell 1 contribute to the most natural and correct development of the root system. The roots are highly branched and reach the slots 6 are subjected to "air processing", which in turn contributes to the formation of active root tips, ready to grow when planting seedlings.

All of the above features make it possible to increase the rigidity of the cell cassette, thereby increasing its service life. Thus, the technical result is achieved.

The inventive seedling cassette can be made on standard equipment from modern materials using modern technologies.
