Problems solved by technology

[0002] When feeding grain from the center of the top of the shallow round silo, the grain falls from a high place. During the process of scattering or flowing, grains or impurities of different types and densities automatically gather in different areas, and heavier impurities and broken grains are mostly concentrated. At the center of the cone, a columnar impurity area is formed, which is easy to breed insects and molds during storage, which affects the ventilation or fumigation effect; at the same time, the height difference of the grain surface is large, and the workload of leveling the grain surface is heavy.

Embodiment 1

[0012] Embodiment 1: A water wave type binning method, which increases or decreases the rotational speed of the chute step by step, and relies on the centrifugal force generated by the grain itself when the chute rotates to form different projectile distances. Under the condition of constant rotational speed and projectile angle Under the action of the rotation of the chute, the grain continuously flows to the fixed ring to form a projecting ring. figure 1 Among them, the numbers 1 to 8 respectively denote projecting rings with different diameters, and control the motor speed level and time to generate multiple concentric projecting rings at the same level. For example, the control motor speeds are A 1 、A 2 、A 3 、A 4 , respectively yielding a diameter D 1 、D 2 、D 3 、D 4 The projecting ring, the ring is the crest, and the junction of the rings is the trough. When the speed of the chute is constant, the angle of projection is also constant. The throwing time of each thro...

Embodiment 2

[0013] Embodiment 2: On the basis of Embodiment 1, the rotation speed of the chute is adjusted to produce layers A and B in different grain distribution methods. A layer and B layer are arranged circularly in turn, and the peaks of the upper and lower layers match the troughs to achieve the purpose of uniform grain distribution. Usually, both the A layer and the B layer will have multiple ejection rings, that is, both the A layer and the B layer will have multiple speed levels. Each rotational speed satisfies A i i i+1 i+1 , where i=1, 2,...n; n is a natural number greater than or equal to 1. i.e. A i i 2 2 3 3 4 4 .... In addition, among the layers A and B, at least one layer contains zero rotation speed, or both layers contain two rotation speeds.

Abstract

The invention discloses a water wave type binning method. According to the method, the rotation speed of a chute is improved or reduced stepwise, different cast distances are formed by centrifugal force generated by grain during the rotation of the chute, and the rotation speed level and time of a motor are controlled, so that a plurality of cast circular rings which are concentric are generated on the same horizontal height. According to the water wave type binning method, a binning mode is similar to water waves; and the method is unique, high in flexibility and good in binning effect, can be realized only by controlling the rotation speed level of the motor and is suitable for automated grain distribution, and a control method is simple, so that the degree of labor participation is reduced, labor is reduced, and the cost is saved.

Description

technical field [0001] The invention relates to grain storage technology, in particular to a water wave storage method. Background technique [0002] When feeding grain from the center of the shallow round silo, the grain falls from a high place. During the process of scattering or flowing, grains or impurities of different types and densities are automatically gathered in different areas, and heavier impurities and broken grains are mostly concentrated. In the center of the cone, a columnar impurity area is formed, which is easy to breed insects and molds during storage, which affects the ventilation or fumigation effect; at the same time, the height difference of the grain surface is large, and the workload of leveling the grain surface is heavy. The current loading method is to change the speed of the chute, increase the drop point, reduce the sliding distance between the grain and impurities, thereby reducing the degree of accumulation of impurities in the center of the ...
