Description

The invention relates to a grain pump according to the Preamble of claim 1.

This grain pump is described in US 23 18 881, has blades made of elastic material to protect the Good on and promote this in free flight, necessarily outside the baffles according to a parabola. The grain pump is rotatable in its housing stored so that they evenly in their litter area the good can distribute circularly.

From DE-GM 82 24 904 and DE-OS 24 21 135 is a To remove throwing blower, in which the ejector tube from Acceleration box starting substantially vertically is arranged to the pivot axis of the vehicle. At the end of the tube is an ejection or blowpipe, with where the goods are distributed accordingly.

Moreover, are currently in the promotion of grain and light bulk goods prefers conveyor belts,  Vacuum pumps, paternoster as well as chain and belt conveyors used. These often have a large mass, since the underlying circulation mechanism not only moves the cargo, but also a sufficient, must have mechanical intrinsic stability. Furthermore are the conveyor speeds due to the installing reduction gear in mechanical Conveyors often low.

For conveyor systems based on compressed air respectively Vacuum is the energy input per ton Cargoes are generally high. This will be given the achievable output generally neglected.

Paternoster are practically only with great effort in existing Buildings (warehouses) to integrate, as Prerequisite a bottom shaft and a corresponding Roof tower are to be regarded.

All systems shown here have in common that they contain a large proportion of mechanical components.

To improve the state of the art is the Object of the invention in specifying a simply constructed, compact, inexpensive, reliable grain pump that the Treated grain gently.

This object is achieved in that  the generic grain pump the characterizing Features of claim 1.

The grain pump according to the invention is based both in the Vertical as well as horizontal movement on the Principle of the throw (of the spin) and considered in the building elements the parabola.

Embodiments of the grain pump are in the drawings and will be described in more detail below.

It shows

Fig. 1 is a vertically conveying grain pump and

Fig. 2 is a horizontally conveying grain pump.

The grain pump consists inter alia of the Acczelerationskasten 2 , in which the paddle wheel 1 is rotatably mounted. This has elastic blades and thus throws the cargo from the Akzelerationskasten. 2

The discharge pipe 5 for conveying the goods in the vertical is straight and ends in a curved, rotatable attachment for discharging the grain stream in the desired direction. On the other hand, the discharge pipe 5 for conveying the goods in the horizontal direction, which of course also includes an oblique direction, a parabolically curved pipe 5 , the bend is oriented to the parabola and to calculate accordingly.

The Acceleration box is easy to create and allows for relatively small dimensions high conveying speeds. In the promotion of grain and similarly sensitive goods, the blades of the blade wheel 1 located in the acceleration box 2 are made of elastic material in order to protect the conveyed material from mechanical damage.

The vertical tube 5 works in conjunction with the aforementioned drive in a short path. Downpipes, distributor, shaft, roof attachment can be omitted for final distribution.

The parabolic tube 5 serves as a horizontal conveyor.

The system described can be very compact and modular be designed so that a mobile use z. B. for loading and unloading lorries or railway wagons can be considered. A limitation arises in wet goods.

Tests in practice and in the lab have shown that the system on the described performance and  Quality features.

The blades of the paddle wheel in the acceleration box were made from the material of car tires. When Drive was an electric motor with 2 kW power.

On this basis was with grain (wheat) a head of 17 meters without damaging the conveyed goods.

The grain pump used in the tests showed the following technical data on:

- Diameter of the paddle wheel | 400 mm - Width of the paddle wheel 120 mm - Height of the blades 120 mm - Number of blades 8 pcs. - engine power 2 kW - pipe diameter 120 mm - delivery height 17 meters - Flow rate 10 t

Claims (2)

1. A grain pump with a paddle wheel ( 1 ) which is rotatably mounted in a Akzelerationskasten ( 2 ), and the grain directed therefrom by means of baffles ( 3, 4 ), which outside of the box ( 2 ) in the horizontal direction corresponding to flying trajectory, characterized in that the grain ejected in a horizontal direction through a pipe (5) is guided, which is formed corresponding to the trajectory, and in that the throwing range over the angle of attack, the bucket-wheel and the amount of control is effected. 2. Grain pump according to claim 1, characterized in that the blades of the paddle wheel ( 1 ) consist of elastic material.
