Hole formation device in complex of equipment for precise seeding for growing seedlings with ZKS

Abstract

The significant use of imported technological equipment is one of the problems in the development of the reforestation complex in the Russian Federation. To reduce the backlog in this area from the level of development of the leading countries of the world, the Order of the Ministry of Natural Resources and Ecology of the Russian Federation dated December 4, 2020 No. 1014 "On approval of the Rules for reforestation, the composition of the reforestation project, the procedure for developing a reforestation project and making changes to it" was adopted. Special attention in it is paid to accelerating the renewal of the technical base. The development of a complex of equipment for precise seeding of seeds, which includes a device for the formation of holes in cassettes with a substrate, which has an adequate cost and does not require complex maintenance, is an urgent topic of this development and research work. The article presents an overview of the production process of growing seedlings with a closed root system (ZKS) in the Green Building Department of Krasnoyarsk, designs of analogues and experimental developments of a hole-forming device. An analysis of the designs of similar devices made it possible to identify the advantages and disadvantages and take into account the development of new equipment for the hole former, determine the design and parameters of the device to optimize the technological process of sowing seeds in cassettes, achieve a device productivity of 20 cassettes / min. That allows to achieve the productivity of the entire complex up to 1200 cassettes per hour (100 thousand seeds per hour), which exceeds foreign and domestic analogues.
