HU198115B - Ventilating cover tarpaulin - Google Patents

Abstract

The object of the application is a ventilation blanket (1) having vents (14) on a water-repellent tarpaulin. The sliding openings with elastic material stiffeners are formed with the ventilation slots so that the vents (14) of the cover sheet (1), when winding the cover sheet (1), are flattened on the sheet material, and when the tarpaulin is laid out, which form the rigid wall vent.

Description

Λ the object of the application is a ventilation blanket which protects the stored material covered by it, such as hay fodder, straw or other material, machinery and equipment against rain, while at the same time providing the stored material with natural ventilation through the air vents on the surface of the tarpaulin. Its field of application is mainly used in agriculture for the storage of hay and straw, fertilizers, raw materials for the flax and hemp industry, high-value machines and containers. It can also be used in industry where, in larger heaps, certain materials need to be protected against the adverse effects of the weather and need to be ventilated because of their properties. In Hungary about 4 million tons of hay is stored annually. Only a fraction of this amount goes into covered storage. Outdoor hay, which represents a significant proportion of the total amount of coal produced, is subject to weather changes similar to straw, so the quality of hay and straw that is harvested in good quality is highly dependent on how it is stored.

So important for the flax and hemp industry, the quality of hemp shells is greatly determined by the dryness of the dried shells after harvest until they are used.

Due to the lack of storage capacity, valuable agrochemicals (eg fertilizers), machinery, implements, etc. are stored. are exposed to adverse weather conditions (ultraviolet radiation, rain, etc.).

For example, several solutions have been devised to maintain the hay contents. The carbon storage method made from large roller boards is also one of the attempts to do so.

Its advantage is that it can be stacked quickly and easily. Well mechanized. Stacking machines can be used advantageously and efficiently in the case of non-starch mowing.

Studies and literature (eg Pap: Mechanized Straw Harvesting, Hungarian Agriculture, Vol. 37, p. 29, p. 5) have concluded that storage losses are still considerable. The bales stored in the heap must be protected against soaking.

Covered storage forms are described by Beke (Field Frame Structure, Hungarian Agriculture, Bp. 35, No. 37, 1980, p. 11), Kárpáti (Storage of Fodder in Covered Colors, Hungarian Agriculture, 1982, Bp. 37, 13). and Soós (Moving the Round Bales, Stacking, Hungarian Agriculture, 1982 Bp. 38, No. 28, p. 9). They have the disadvantage that they can be tailored to meet local needs and can be produced in large series in a lesser way. They are also expensive to build. Their unloading is difficult to mechanize.

There have also been attempts to cover with plastic foil, for example. However, the films were vulnerable. In case of airtight closure, this method of covering caused hammering and drought on hay and straw.

Covering with plastic foil is not a satisfactory solution either. This is stated by BÁNHÁZI in the section entitled “Mechanization of forage production”. (Hungarian Agriculture, Bp. 1977, Vol. 39, p. 14).

Miatt Concentrated cattle sheds do not allow individual storage of large bales outdoors because they require large space. Another disadvantage is that after four to five months of storage, the bales rot in the open (PAPP "Mechanized Straw Harvesting," Hungarian Agriculture, Bp. 1982, Vol. 37, No. 29,

Page 5).

The specialist offices reviewed in this topic seem to be omitting, and more and more professionals are convinced that making and storing widespread large bales does not solve the problem of lossless storage of stored material. The insecurity in this area and the inertia resulting from the lack of a solution are causing huge storage losses.

The storage conditions of high-value machines and equipment are similarly inadequate. For example, $ 2-3 million harvester threshing machines work for about 2 months a year and then continue to be exposed to outdoor damage until next year, for example. rust. The same can be said about the storage of many other valuable raw materials, containers, which are not solved cheaply and safely.

It is an object of the present invention to provide a tarpaulin that provides adequate protection of stored materials, devices against the adverse effects of the weather (rain, sunshine, etc.), but at the same time prevents the stored material, device, from being stuffed, corroded, etc.

The invention thus provides a ventilation blanket having a tapered or truncated cone shell on its longitudinal axis which is water repellent or waterproof. Judicial vents are conveniently arranged. Curved wind stiffeners are provided on the flanges of the ventilation shells facing the ventilation slots. Λ water baffles with the same plane as the canopy penetrate into the vents formed by the ventilation shrouds and the canopy plane. Straight wind stiffeners or "L" sectional baffles are attached to the baffles or plates: evenings.

The ventilation awning according to the present invention is based on the discovery that a water-repellent or waterproof material awning known per se is provided with tension-sheathing vents which also allow it to be folded. The ventilation blanket thus formed protects the stored material, e.g. fodder, bulk fertilizers, agricultural and forestry implements, etc. on the other hand, ensures a natural ventilation of the covered materials.

The ventilated shells and the baffle plates are made of particularly well-waterproof, water-repellent or waterproof material. Straight and curved wind shields are rods or battens.

The ventilation awning is configured such that the ventilation awnings are flush with the awning due to the flexibility of the arch stiffeners of the vent opening and the opening of the vent opening when folded.

In one embodiment of the ventilation awning according to the invention, the fans are formed over the entire surface of the awning.

In another embodiment, the ventilation awning according to the present invention is located along the spine line of the awning - the device, material, material,

Depending on the size and shape of the 115 products, like the axis of symmetry, the vents are designed so that they are only on the side panel of the canopy.

The invention will now be described in more detail with reference to the drawings. In the accompanying drawings, Fig. 1 is a side view of a possible embodiment of the awning fan according to the invention, Fig. 2 is a front view of the awning fan shown in Figure 1, Fig. 3 is a side view of another embodiment of the awning fan; Figure 5 is a front view of the cover awning vent shown in Figure 3; Figure 5 is a possible embodiment of the use of the cover awning according to the invention;

Figures 7 and 8 illustrate other possible embodiments of a vent cover.

Example 1

1 and 2 illustrate one embodiment of the vents 14 of the exemplary vent cover 1. The vent opening 2 is bounded on the bottom by the baffle plate 8, on the side and on the top by the vent shell 7 and the curved wind brace 4 in the vent shell 7. All straight wind braces are glued to the material of the baffle plate 9. The curved wind stiffener 4 is secured to the material of the ventilation shroud 7 and the ventilation shell 7 is secured to the material of the tarpaulin 1 by sewing 13. The baffle plate 9 extends into the vent 2 at a depth such that tap rain cannot reach the stored material 8. Here, the baffle plate 9 is made of the material of the tarpaulin 1.

Example 2

In Figures 3 and 4, the ventilation shell 7 is bonded to the cover sheet 1 by adhesive. A water deflector body 12 having an "L" cross section for stiffening is also glued to the baffle plate 9. The baffle plate 9, like the vent shell 7, is made of a material which is particularly well-water-repellent, water-repellent or impermeable and is sewn to the cover sheet 1.

Example 3

In the example shown in Figure 5, the stored material 8 is an agricultural power plant. Here, the vents 14 are placed on the cover 1 so as to allow proper storage.

Example 4

In Figure 6, the stored material is a cylindrical bale, which may be a paper or a feed bale. The stored material 8 is placed on a nozzle layer 5, e.g. The tarpaulin 1 is secured to the material 8 by means of fixing lugs 10. Drainage ditches 6 are formed on both sides of the material 8 stored outdoors.

Example 5

In Figure 7, the stored material 8 is a cylindrical feed bale. The tarpaulin 1 is clamped by the tabs 3 securing the tarpaulin to the stored material 8. The stored material 8 is surrounded by drainage ditches 6. '

Example 6

In Figure 8, the stored material 8 is bulk lucerne carbon. Straw 5 is placed under the bulk material 8 as an absorbent layer. A drainage ditch 6 is drawn on each side of the stored material 8.

An outstanding feature of the ventilation drape according to the invention is that, despite the special design of the ventilators with stiffeners, they can be rolled up. It does not require more storage space than traditional tarpaulins. An advantage of the present invention is that storing the straw meals in a heap eliminates storage loss and loss of quality due to soaking, and prevents butterfly feeding of moths due to soaking. Protects stored materials and machinery from the adverse effects of falling rain. A further advantage over traditional waterproof tarpaulins and plastic sheeting is that the materials and equipment stored (indirect corrosion protection) are provided with natural ventilation through the vents. It allows for the escape of condensed water, condensate, gases and excess heat generated by protected materials.

Külön A special advantage of vented blankets over conventionally installed stable storage units is that they are easy to move, transport and cost less per unit area.
