Embodiment Construction

[0010] The rubber roller husker 1 for husking rice has a housing 2 in the upper part of which a vibrating feeder 3 is provided below a material inlet 4 . Below the vibrating feeder 3 is a pair of inclined rubber rollers 7, 8, wherein the rubber roller 8 is movable. A feed chute 5 is arranged around the pivot 9 in a manner almost perpendicular to the center line of the rubber rollers 7, 8, and rotates between the vibrating feeder 3 and the pair of rollers, whereby the feed chute 5 Base and nip are in line. By precise operation of the vibratory feeder 3, the paddy is guided to the nip through the feed chute 5 in 1-2 layers. In addition, the vibrating feeder has a vibrating channel 17 with a relief cone in its inlet. The operating frequency of the vibrating channel is adapted to the channel vibrating system by the frequency conversion controller 18 .

[0011] Below the above-mentioned rollers 7, 8 there is an outlet 6 for husking paddy and paddy husks, whereby the husking padd...

Abstract

The present invention relates to a roll-type sheller, particularly a rubber roll sheller (1) for rice of other grain. The sheller comprises a level mechanism (11-13), the lever mechanism connects to a slant feeding groove (5),a movable roll, and shell of the roll-type sheller by using the lever mechanism in terms of following way, that is the slant feeding groove (5) sequentially sends grain into roll gap (10) by excursion of support point of the movable roll (8).

Description

field of invention [0001] The present invention relates to a roller sheller for grain, especially for shelling paddy or other grain, preferably removing the shell of the grain. Background technique [0002] A roller sheller of this type is already known, for example from DE-C-2705334. These roller shellers have several rubber rollers controlled by pneumatic pressure. The grain material enters the nip between the horizontally arranged rollers along the center through a feed pipe. [0003] These rollers are placed in suspension. With the belt transported around a drive roller, two rollers and a trim roller, stable belt tension is obtained without tension adjustments. In order to subject the two rolls to the same wear, the two rolls must be exchanged several times, which not only results in high maintenance costs, but also causes an offset of the optimum feed point relative to the roll gap. [0004] Thus, in GB-PS797372 a feed chute has been proposed which is dependent on t...
