DE3824317A1 - Rotatably mounted, hand-operated or motor-operated sieve drum for soils, composts, sand, building materials and the like - Google Patents

Abstract

Technical problem and aim of the invention The sieve drum serves for separating sand, building materials, soils and in particular clump-forming composts to as great an extent as possible with low effort. The known technical embodiments are screens and riddlers which allow an extensive separation only with difficulty or not at all. If this is at all possible, relatively high effort is involved. Solution of the technical problem The sieve drum is mounted rotatably on a support frame and, during rotating of the drum at the rotating handle or by the motor or, in the special embodiment, by the concrete-mixing machine, materials which adhere together firmly are sieved without problems and soils and composts which adhere together firmly are broken up and sieved with relatively low effort. Area of application Sieving of sand, building materials, breaking up soils and composts and sieving in one operation to achieve a homogeneous mixture, e.g. for horticulture.

Description

Genre of the object of registration

The invention relates to a screening drum for different materials after Preamble of claim 1.

Information on the genus

The separation of the grains or the like Mate rialien should on the one hand, if possible allows little effort and others made as far as possible will.

State of the art with sites

It is known to accomplish this Requirements so-called throw-through sieves on which to be screened Material is abandoned and through the Mesh the sieve partially through falls.

Critique of the state of the art

However, it is necessary to do the above course of loading with the under different materials so often repeat until adequate door grain size is done. In which Process become clumped and together hanging parts only relatively minor crushed or separated. Moist, clumpy earth and especially their composts can be knew technical facilities in private area usually does not rule out shred sufficiently or from each other separate.

task

The invention is based on the object with as little effort as possible appropriate separation of materials (grain size) from each other and thereby ver at the same time in the same operation clumped and cohesive parts crush and the remaining frag elements to separate the sieved material a homogeneous structure to reach.

solution

This object is achieved according to the invention solved that the sieve drum rotatably is arranged and by the to be carried out Rotational movement of the separation or crushing The materials are used.

Further embodiment of the invention

By inserting different sieve mats made of wire or plastic Sieve drum a grain with any desired th degree of fineness can be achieved.

Achievable advantages

The advantages achievable with the invention consist in particular in that the existing technical possibilities with the least effort and assistance of deposits of different meshes spread any desired grain size with the largest possible separation or crushing and subsequent separation of the grits into one operation as efficiently as possible is achieved.

Description, working examples Embodiment I

It shows Fig. 1 - the sieve drum is rotatably mounted on a support tube which is ausgebil det in the upper region as an axis and can be manually moved by the rotary handle attached to the outer edge.

In addition, an electronic or internal combustion engine, via a drive element (e.g. belt driven) the drum turns.  

Embodiment II

There is shown in FIG. 2 - a aufmontierte on a concrete mixer drum screen which is fixed only by a flat iron at the mixing drum. In this version, a continuous loading can take place until a certain degree of saturation with a grain size that can no longer penetrate the mesh size is reached.

Claims (5)

Generic term 1. Rotatable, manual or motorized driven sieve drum for soil, compost, Sand, building materials and the like. Characteristic part Characterized in that the Siebtrom mel can be Gert gela rotatably on a support tube and rotated by a rotary handle in Rotie Rende movements or is flanged thereto in a further embodiment as to spare parts to concrete mixer at this itself. Preamble of the dependent claim 2. Screen drum according to claim 1. Characteristic part of the subclaim Characterized in that the Siebtrom mel also actuated by motor drive can be done. It can also be differentiated with an insert Licher mesh z. B. made of wire or Plastic to achieve any size can be additionally equipped.
