Description

[0001] PROTECTIVE CAP FRAME

[0002] Field of technology

[0003] The utility model relates to agriculture, namely to protective cap frames for sheltering plants from adverse weather conditions, primarily from frost.

[0004] Prior art

[0005] A frame for a protective cap for covering plants is known, containing arcuate ribs made of wire fastened together, the base of which is made in the form of a circle by connecting the ends of a piece of wire, and the ribs are made from pieces of wire connected to each other in a bundle by some of their ends, and by the other ends connected to the base of the frame and evenly distributed along its circumference (RU 98324 U1).

[0006] A plant cover is known, made of two triangular end walls and a pair of side walls, hinged to each other along the longitudinal edges and formed from at least one rectangular flexible sheet of plastic, wherein the walls are supported by a series of ribs, some of which rest against other ribs adjacent to the hinge. The ribs may be placed in bushings extending across the side walls and formed by welding strips of plastic to the side wall; the ribs may be metal and curved at one end, forming a support with a hole for installing an anchor pin; the ends of the cover are secured in a given position by connecting strips welded along two adjacent edges of each end wall and the edges of the side walls; reinforcing strips are also welded along the ridge and lower edges of the side walls (GB 1139741 A).

[0007] A protective cap is known, comprising arcuate ribs connected at their upper ends by a horizontal ring. These ribs are constructed as elastic bands, also connected to horizontal bands connecting the ribs. The device is equipped with a central post, rigidly attached at one end to the top of the cap, and at the other end, driven into the ground to secure the cap in place. The device has a flexible covering rigidly attached to the arcuate ribs (US 2405452 A).

[0008] A shelter for growing vegetable crops is known, comprising vertical supports, arcs pivotally connected to them, and a protective material. The shelter has lateral arcs connected by longitudinal crossbars at their lower and upper portions; movable supports freely movable along the vertical supports and pivotally connected to the lateral arcs at their upper portions; fixed supports mounted on the vertical supports at their lower portions and pivotally connected by connecting links to the lateral arcs at a certain distance from their upper hinge joint; and roof brackets mounted on top of the vertical supports and connected by longitudinal crossbars (RU 2347356 C1).

[0009] A plant growing shelter is known, comprising a frame of vertically mounted wire arches, onto which a tubular film with a tension member at the top is placed. Horizontally positioned wire rings are attached to the film or frame to reduce the film's sag in the gaps between the frame arches (SU 1688803 A1).

[0010] A shelter for growing plants is known, which includes frame posts and a covering made of flexible material mounted on them, in which the frame posts are made in the form of separate elements having the shape of a knitting needle with an upper end folded into an eye, installed with the lower ends spaced apart and with the eyes placed close to each other, while the covering is made in the form of a two-layer fabric in the shape of a triangle or trapezoid with an open base, which, when mounted on the frame posts, forms a pyramidal cap, turning into a bent peripheral part of the fabric adjacent to the ground (Yai 99923 U1, 12 / 10 / 2010, IPC A01G 13 / 02).

[0011] A protective cap is known comprising arcuate ribs, formed as elastic strips, interconnected at their upper ends and via a hinge, and a flexible covering secured to only two adjacent ribs, on which the mating parts of the lock are also mounted. When the cap is in operation, the adjacent ribs, to which the covering is secured, are first moved apart and then connected to each other by locking elements. This causes all the hinged arcuate ribs to rotate, and the cap acquires a spatial shape in which the covering is supported from below by the aforementioned ribs. When the product is not in operation, the arcuate ribs, made of elastic material, straighten and fold into a stack (SU 1616549 A1).

[0012] A common drawback of existing technical solutions is their poor performance due to the limited lifespan of the covering material. Due to wind and snow loads, the covering material sags into the gaps between the frame arches and quickly fails, requiring annual replacement. Such covers also do not guarantee the protection of plants from mechanical damage. Interseasonal disassembly and reassembly of the covers, including replacement of the covering material, create additional material and labor costs.

[0013] The closest in terms of the set of essential features to the claimed technical solution is a protective cap containing a frame and a covering device, in which the frame is made in the form of a solid, hollow structure open at the bottom, having a shape symmetrical relative to the axis of the frame, smoothly tapering from the base upwards to a closure at the top, the covering device is made in the form of a hat made of covering material with an internal shape repeating the external shape of the frame (RU 216415 U1.

[0014] Although this protective cap guarantees the protection of plants from mechanical damage, its use eliminates the need for annual replacement of the covering material and allows for a reduction in labor costs, it does have a significant drawback.

[0015] The disadvantage of this design is that it is weakly secured to the ground, which does not provide reliable cover for plants under strong wind loads.

[0016] Disclosure of a utility model

[0017] The technical result is the creation of a protective cap frame that ensures its reliable fixation to the ground and covers plants under any wind loads.

[0018] The technical result is achieved due to the fact that the frame of the protective cap for sheltering plants from adverse weather conditions is made in the form of a hollow structure open at the bottom, having a shape symmetrical relative to the axis of the frame, smoothly tapering from the base upwards to a closure at the top, and in the lower part touching the ground, there are tabs bent towards the outer side of the frame.

[0019] The listed essential features of the claimed frame allow for the expansion of its functional capabilities during operation, namely, ensuring its reliable fastening to the ground, guaranteeing the shelter of plants under any wind loads.

[0020] The frame can be made of a high-strength composite material. An opening can be made on the top surface of the frame, and four vertically spaced rows of windows can be made on the side surface, symmetrically positioned relative to the frame axis.

[0021] The lower contour of the frame can be made with a stiffening edge bent towards the outer side of the frame.

[0022] The base of the frame can be made in the shape of a ring.

[0023] The paws can be made parallel to the base.

[0024] The paws can be made with holes.

[0025] The frame can be made in one piece.

[0026] The frame can be made prefabricated.

[0027] The frame can be made with stiffening ribs.

[0028] Brief description of the drawings

[0029] The claimed device is illustrated by figures:

[0030] Fig. 1 - protective cap frame, general side view;

[0031] Fig. 2 - frame, top view.

[0032] Implementation of a utility model

[0033] Frame 1 is a single, hollow structure made of high-strength composite material, open at the bottom and ring-shaped at the base. The body is formed by a ring that gradually tapers in diameter as it moves upward symmetrically along the frame axis until it fully closes at the apex. The frame may also be constructed from individual elements. An opening is provided on the upper surface of the frame, and four vertically spaced rows of windows are provided on the side surface, each symmetrically positioned relative to the frame axis (the vertical axis). The lower portion, touching the ground, is provided with at least one tab 2, bent toward the outer side of the frame parallel to the base, with an opening for securing it to the ground. The lower contour of the frame is provided with a stiffening flange 3, bent toward the outer side of the frame. Depending on the thickness of the material, the frame may be provided with stiffening ribs.Windows on the frame and its base can be made in the shape of any geometric figure.

[0034] All of the above-mentioned features of the formula ensure reliable fastening to the ground and, as a result, provide reliable shelter and its safety during the winter period under any wind loads.

[0035] Thus, the technical result has been achieved. The claimed protective cap frame meets industrial applicability requirements and can be manufactured on standard equipment using modern materials and technologies.
