Description

The proposed utility model relates to agriculture and can be used for sheltering crops in personal subsidiary plots, farms and collective agricultural enterprises.

The production of heat-loving vegetables in many climatic zones is impossible without plant protection from the adverse effects of the external environment. To protect plants in open ground, temporary enclosing structures are used that do not have a foundation and equipment for heating. These include large-sized and small-sized tunnels and frameless shelters (see Goncharuk B.C. Polymers in vegetable growing. - M: Kolos, 1971. - pp. 44-45).

Small-sized frame tunnel shelters are wire arcs placed at a distance of 1 m from each other and interconnected on top of the twine. On top of the arc are covered with a film, the edges of which are sprinkled with earth. Oversized tunnels have large overall dimensions, so they create the best thermal conditions. The framework of such tunnels is based on plastic or metal pipes. The width of the tunnels is 1.5–4.5 m, the height is 80–200 cm, and the length is 20–30 m. The design options differ in the sizes and methods of film fastening.

A drawback of tunnel-type film frame shelters is the great laboriousness of work related to ventilation, and depending on changes in the external environment, it is necessary to manually open and close the shelter several times during the day, eliminating overheating when the sun appears. When using shelters at the growing site throughout the growing season, the design of the shelter makes it difficult to carry out plant care operations. In addition, atmospheric precipitation moisture drains from the surface of the shelter and does not enter the zone of the root system of plants, but for artificial irrigation, on the contrary, removal of the shelter is required.

Partially, these shortcomings were eliminated in a folding film shelter (Grishkevich MN Use of polymer films on heated soil in Belarus // Plastic films in vegetable growing. Scientific works of AFI. - M .: Kolos, 1967. P. 134-140). Shelter consists of side boards fastened with rafters. The rafters are interconnected in the ridge using a hinge. The installed frame is covered with a film on top. The edges of the film are attached with twine and nails to the longitudinal bars (bobbins) on which it is wound for ventilation.

There is an option for fixed mounting of the film to the walls of the shelter. In this case, ventilation is carried out by lifting one side of the shelter and resting it on a peg.

To perform technological operations (for example, inter-row cultivation or irrigation), it is possible to increase the lifting height of one side of the shelter or moving it into the passage between the rows of plants. But in the latter case, it does not fulfill the function of shelter.

A shelter for plants with a film coating is known, consisting of the same type of details of flat flexible arched elements that are mounted on the base (on the soil surface) in pairs one above the other crosswise at an angle to each other, and the flat flexible arched elements are interconnected by a flexible element at the intersection with each other and between adjacent pairs (see RF patent for the invention No. 2268580, CL A01G 9/14, 2004).

The disadvantage of this device for sheltering plants is the difficulty of access to plants (the difficulty of opening and closing).

The closest in technical essence to the proposed one is a device for sheltering plants, containing with a light-transmitting coating a frame of the same arch elements, thrust posts with stop elements, a stop, a rectangular base with at least four pockets, while the same type of arch frame elements are rigidly interconnected, and the frame itself is equipped with limiters for its movement, rigidly mounted at the ends of at least the end arched elements of the frame with the possibility of movement in the pocket in planes , in which the axial lines of the arch elements lie, as well as with the possibility of entering (exiting) from it, the thrust posts are rigidly mounted on the base in a plane passing through the center line of the central arch element, one end of the stop is pivotally mounted on the central arched element with the possibility of movement in the plane passing through the center line of the central arch element, while the stop length is chosen such that the second end has the ability to alternately contact each of the locking elements (see Patent RU No. 2437275, M. Cl .: A01G 13/02, 2011).

The disadvantage of this device is the difficulty of manufacturing due to the need to maintain high accuracy of component arcs, the complexity of the design due to the presence of a locking mechanism in the middle of the device, which is an obstacle to plant growth, the need to fix any open position of the device, a large range of parts.

The technical result of the proposed utility model is to simplify the design and its manufacture.

The design of the proposed plant shelter device is disclosed in the drawings, where in FIG. 1 shows the proposed device for sheltering plants in a closed state, FIG. 2 is a state of a device in which it is partially open from the left side, in FIG. 3 is a state of a device in which it is open more than in FIG. 2: in FIG. 4 is a state of a device in which it is partially open from the right side, in FIG. 5 is a state of a device in which it is open more than in FIG. 4: in FIG. 6 - FIG. 10 shows the positions of the latch 14 for various options for opening the device from the left side (the positions of the latch 14 for various options for opening the device from the right side are not shown) - arcs 2 and 3 are not shown in these drawings; in FIG. 11 shows an embodiment using an open position lock 17.

The device for sheltering plants contains a base 1 (base 1 is rigidly fixed in the ground - fixing the base 1 in the ground is not shown), with a light-transmitting coating (light-transmitting coating is not shown in the drawings) a frame of the same arch elements 2 and 3. 4 and 5. Arched elements 2 and 3 parallel to each other are rigidly fixed to the frame 1, with the formation of the sides. Arched elements 4 and 5 are rigidly connected to each other at the ends of the arcs using elements 6 and 7 and are installed between arched elements 2 and 3 with the possibility of changing the spatial position relative to the base. Arched elements 2 and 3 are equipped with vertical stiffeners, respectively, 8 and 9. Vertical racks 8 and 9 connect the upper point of each arched element 2 and 3 with the base. On each rack 8 and 9, two levers 10 and 11, 12 and 13, respectively, pivotally connected to the ends of the second arcs 4 and 5, respectively, are pivotally mounted at the same height. The height at which the levers of tinctures 8 and 9 are pivotally mounted determines the force at which the device for sheltering plants can be opened. The optimum height is determined experimentally or by calculation.

To reliably fix the position of the unopened side, two latches are used (only one latch 14 is shown in the drawings, located on the right side of the device, not shown on the left) of the position of the rigid links 6 and 7 of the arches of the arch elements 4 and 5 with the device open, having the ability to change spatial position, each of which is installed on the corresponding rigid bunch of arched elements having the ability to change the spatial position. The optimal position of the latch 14 in the middle of the bonds 6 and 7.

For the convenience of opening the device on a bunch of 6 and 7 arched elements 4 and 5 mounted handles 15 and 16, respectively.

On the levers 10-13, latches 17 of the open state of the device are installed (the drawings show the latch 17 only in Fig. 11 - the rest are not shown). The latch 17 is in the simplest case, a metal rod with bent ends 90 degrees in opposite directions (in the drawings the design of the latch 17 is not explained). Arcs 2-5 on the respective sides have holes (not shown in the drawings) to accommodate the latches 17.

A device for sheltering plants as follows.

To open the plants, take handle 15 or 16 and raise the arcs 4 and 5 up. The degree of opening is determined by the user. The open position can be fixed by the corresponding latch 17. To close the plants, the device is locked by the latch 17, take the corresponding handle, lower it and close the device. Plants are closed.

To exclude structural damage during strong or heavy wind or one hundred gusts, elements 14 and 17 are included in the work.

Due to the fact that the arcs 4 and 5 work like springs, their reliable fixation of the fully open and fully closed position without using the element 17 is ensured.

The proposed design of the device for sheltering plants can work well with automatic devices for opening and closing, built on the effect of expansion of the liquid when the ambient temperature changes.

Rectangular tubes were used as the material in the described design of the plant shelter device.

The simplicity of the design while simplifying the manufacture is the advantage and advantage of the proposed technical solution compared to the prototype.
