Abstract

The invention relates to a device for covering Futtermitteloberflaechen with flexible geomembranes at Gruenfuttersilagen. The aim of the invention is to reduce the manual effort and the cost of food storage and to create better conditions for industriemaenzigen Produktionsprozesz. The inventive solution provides for the convex shaped feedstock a tensile and wear resistant waterproof cover material, e.g. Tarpaulin fabric, which is tensioned by means of two rollers 1 on the tensioning devices arranged on either side of the feedstock in such a way that the necessary uniform pressure for feeding is achieved without the use of additional material for weighting.

field of use

The invention relates to the field of storage of agricultural bulk materials and animal feed, which are stored in free warehouses and open horizontal silos or «conserved. In order to comply with defined quality parameters or biological conditions, the stored goods must be protected from moisture, moisture and unimpeded access to oxygen by covering.

Characteristic of the known technical solutions

Are known various types of Zueckens of storage goods bzwe the feedstock with plastic films or coated fabrics that are complained to achieve the required contact pressure with soil, Altsilage, car tires USWo or - as described in the GDR patents WP 100614 and WP 72415 - by Anchoring devices or ropes are pressed _o The application of soil and Altsilage requires a relatively high manual effort and has an inhibiting effect on the industrial production process in the management of silos or outdoor storage. Furthermore, damage to the film during manual distribution de3 load material and contamination of the feed can not be avoided.

The achievement of a punctiform or linear pressure

Pressure through anchor or ropes is not enough to create anaerobic conditions in the feed stack.

Object of the invention "

The purpose of the invention is to eliminate the described disadvantages, which adhere to the known solutions. In addition, by reducing the manual effort, an increase in labor productivity and reduction of costs is achieved and better conditions for the industrial production process of the feed storage are created.

The economic effect of the inventive solution to be achieved by the multiple use of Zudeckmaterials, the elimination of the previously manually applied and evenly distributed ballast material and a saving in manpower, the amount of which was based on the size of the plant Other, not yet quantifiable advantages are: Reduction of feed losses by avoiding contamination of the stored goods and initial adaptation of the work process to the industrial feed production.

Explanation of the essence of the invention

The invention has for its object to develop a device for covering of feedstock surfaces, which creates better gärbiologische conditions as a prerequisite for the production of quality food and reduction of feed losses by uniform contact pressure of Zudeckmaterials on the feedstock surface eliminates the manual effort for the application of the weighting material and thus for the first time creates conditions for the classification of this operation in the already existing industriemäßigen production process, a destruction of the Zudeckmaterials by mechanical stresses, such as through pointed tools (spades,

Schippen, Gripper ο. Like.) Excludes and allows repeated use of the most expensive Zudeckmaterials.

According to the invention the object is achieved in which the required contact pressure is generated by the Zudeckmaterial itself, ie without additional weighting or anderwei-, tige devices.

This is achieved by clamping devices, which are each arranged laterally stationary from the feed stack. These devices, e.g. designed as rigid tube cross-sections, are rotatable in its axis. In the static state, the entire Zudeckmaterial is rolled up on a jig. The cover material consists of tensile and wear-resistant watertight sheets, e.g. Plan laminates. After completion of the filling and the mechanical compaction of the feedstock which has been introduced between the jigs with convex cross section, the covering material is rolled by the jig, pulled over the lotterstock and anchored to the opposite jig. Thereafter, the tarpaulin layer material is clamped so far by counter rotating both tensioners that a required for the respective storage product contact pressure for the entire storage time arises. After reaching this pressure, a locking of both clamping devices.

After completion of the storage period and before removing the putter, the procedure is reversed. The tarpaulin off is rolled up on a device and is ready for the next filling.
