Description

Automatic rice huller for household small grain processing machine

Technical Field

The invention relates to the technical field of agricultural product processing, in particular to an automatic rice hulling device of a household small-sized grain processing machine.

Background

Rice huller is a step of hulling rice, and its machine is called rice huller. The quality of the rice huller is related to the quality of the rice and the operation of the rice huller. Fully understand the technological characteristics of paddy, help improving the hulling rate of rice huller, the damage of broken brown rice and brown rice surface when reducing the hulling, increase of production, reduce and consume. Today, the rice hulling method and principle includes: extruding, rubbing and tearing to remove the hull, namely a method that two sides of the paddy are subjected to two different movement speeds; the end pressing, rubbing and peeling refers to a method for peeling glumes of grains by the extrusion and rubbing of two working surfaces with different movement speeds; impact shelling refers to a method for shelling grains moving at high speed by impacting a fixed working surface. The squeezing, rubbing and tearing shelling method is the most common shelling method, and two sides of the paddy are respectively in close contact with two rollers which do not move at the same speed and are squeezed. If the rotating speeds of the two rollers are different, the fast roller generates downward friction force on the paddy to enable grains to move downwards, and the slow roller generates upward friction force on the paddy to prevent the grains from moving downwards along with the fast roller. This creates a pair of oppositely directed frictional forces on either side of the grain. Under the action of the extrusion force and the friction force, the chaff generates deformation such as stretching, shearing, twisting and the like, and the combined effect of the deformation is called tearing and rubbing action. When the tearing and rubbing force is larger than the binding force of the inner and outer glumes of the rice husk, the rice husk can be torn to separate from the brown rice, thereby achieving the aim of hulling.

According to the squeezing, rubbing and tearing shelling principle, corresponding rice hulling equipment is prepared, and a plurality of defects also exist in the using process of the existing rice hulling equipment, such as: the rotational speed of rice huller roller is the same, is difficult for going on shelling to the corn, easily causes the damage or can't take off the corn completely to the corn, and prior art has carried out certain improvement to rice huller equipment structure, and above-mentioned problem obtains certain improvement, nevertheless still needs further improvement, improves the hulling rate of rice huller, and coarse garrulous and brown rice surface's when reducing the hulling damage improves output, reduces consumption.

In addition, current rice hulling equipment still has the long back of rubber roll operating time, the rubber roll can be piled up because of remaining grain of rice or chaff and cause the dead condition of stall card, can't accomplish to carry out timely restoration to the rubber roll, simultaneously can't control the flow size of corn well, cause the condition that the feed opening blockked up easily, traditional equipment can not accomplish well to collect the corn of processing completion, and equipment is too heavy inconvenient to remove, also be inconvenient operation when reinforced, extravagant manpower and materials.
