Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to equipment used in reclamation of disturbed lands and in agriculture as protection of agricultural lands against acid rains and maintenance of thermal conditions of concealed surfaces as they grow. Covering movable device comprises drive drum with covering cloth and traction flexible links covering blocks. Proposed device comprises telescopic elliptical posts to change the height of entire covering cloth or its one edge and side rolls with flexible webs. Sliding elliptical stands are equipped with sliding carriages, on one pair of which drive drum and shafts of side rolls with flexible webs are mounted. On the opposite side of the pair of carriages blocks and shafts of side rolls with flexible webs are mounted, which can move along vertical after movement along the vertical of covering sheet and with possibility of winding and unwinding of flexible side webs from rolls. Lower edges of side webs are provided with weights.

EFFECT: invention provides creation of thermal mode of concealed surfaces due to mobility along vertical of flexible webs and its preservation as plants grow, as well as protection of plants from acid rain and production of import-substituting ecologically clean products.

Description

Shelter mobile device refers to equipment for the restoration of disturbed lands and for agriculture as a protection of agricultural plants from acid rain and ensuring the preservation of the thermal regime of the covered surfaces as they grow.

Known covering devices containing a drive drum with a flexible covering sheet, traction flexible connections covering blocks (Patent No. 2198966. Covering device. Authors: Davydov S.Ya., Chernomurov FM, Yugay FS, publ. 20.02. 2003. Bull. No. 5 and patent No. 2543625. Shelter device Authors: Davydov SL, Kosareva NP, Valiev NG, publ. March 10, 2015. Bull. No. 2).

However, the known covering devices do not provide lateral shelters of the covered surfaces and the change in height above them as the plants grow.

Also known is a covering mobile device comprising a drive drum with a covering sheet, traction flexible connections covering blocks, movable elliptical racks for changing the height of the covering sheet or one of its edges, and rolls with flexible side sheets. (Patent No. 153240. Covering device. Authors: Davydov S.Ya., Valiev NG, Semin AN, publ. 07/10/2015. Bull. No. 19).

In this device, side shelters do not have the ability to change the height above the covered surface as the plants grow. Flexible webs do not provide adequate cover for the side surfaces of plants.

The development objective is to ensure the thermal regime of the covered surfaces due to the vertical mobility of flexible paintings and its preservation as the plants grow, as well as to protect plants from acid rain and obtain import-substituting environmentally friendly products.

The task is achieved in that in a covering device comprising a drive drum with a covering sheet, traction flexible connections covering blocks, movable elliptical stands for changing the height of the covering sheet or one of its edges and side rolls with flexible sheets, sliding elliptical stands are provided with sliding carriages, on one pair of which the drive drum and side roll shafts with flexible webs are mounted, and on the opposite side of the pair of carriages, the side roll blocks and shafts with flexible webs are mounted olotnami that are able to move vertically following the vertical movement and a covering web, with the winding and unwinding of flexible lateral webs from rolls, the lower edges of the side webs are provided with weighting.

In FIG. 1 is a diagram of a covering device; in FIG. 2 is a schematic illustration of the operation of a lifting device.

The cover device comprises a drive drum 1 with a flexible cover sheet 2 wound on it. Flexible traction links 3 cover the blocks 4. Sliding elliptical racks 5 have the ability to expand vertically, raising and lowering the cover sheet 2. Rolls 6 for winding and reeling up the flexible side sheets 7 mounted along traction flexible links 3. Drive devices 8 of each elliptical strut 5 are designed to change the height of the entire covering flexible web 2 or one of its edges to form an inclined surface and this canvas. On the shafts 9 are installed rolls 6 with wound flexible lateral webs 7, the ends of the lower edges of which are equipped with weighting agents 10, for example, in the form of a solid bar. The sliding carriages 11 are able to move vertically of the elliptical struts 5 together with the drum 1 and the rolls 6. On one pair of carriages 11 a drive drum 1 and shafts 9 of the side rolls 6 with flexible webs 7 are mounted, and blocks 4 and shafts are mounted on the opposite side of the pair of carriages 9 side rolls 6 with flexible webs 7. Bearing units 12 are supports of the rotating drum 1.

Under the action of the drive, the electric drive of the drive drum 1 also sets in motion flexible traction links 3, which pull the cover sheet 2 to close or open the covered surfaces. At the same time, the other end of the cover sheet 2 is unwound or wound around the drive drum 1. If necessary, the height of the entire cover sheet 2 or one of its edges is changed to form an inclined surface, the drive devices 8 are used. Under the action of the drive devices 8, the movable elliptical racks 5 move apart vertically. As a result, the sliding carriage 11 is raised and lowered together with the drum 1 with the cover sheet 2 and the roll 6 with flexible sheets 7. When the side surfaces of the shafts 9 and the elliptical posts 5 come in contact, the shafts 9 with the rolls 6 rotate due to friction, winding and unwinding the flexible films 7 Weighting agents 10 in the form of a solid bar provide a constant tension of the films 7 vertically.

The use of the device for the covering areas of agricultural plants in the fields and in large greenhouse farms allows you to adjust the height of the sample of the canvas following the growing plants. A greenhouse effect is created to create an accelerated rotting process of soil mixtures with decay products and plant growth process. Using the device for additional sheltering of agricultural plants in heated greenhouse farms can significantly reduce energy consumption, and when sheltering agricultural plants in the fields, it will protect plants from acid rain and get import-substituting environmentally friendly products.
