Problems solved by technology

As a result, the speed and angle at the time of the collision of the lining sometimes deviate from the state suitable for shelling, and in this case, shelling may not be performed satisfactorily.
In other words, the husking rate may decrease due to large deviations in the throwing direction and throwing speed of rice

Embodiment approach

[0111](1) In the above-mentioned embodiment, only the outer guide surface 29 is formed on the radially outer end portion of the rice guide assembly 21 as the inner shelling portion. A radially outer end portion of the shell portion is formed with a protrusion structure that protrudes radially outward and widens toward the rotation axis.

[0112] Such as Figure 15 As shown, at the radially outer end portion of the rice guide assembly 21 as the inner husking part, an outer guide surface 29 set to be substantially parallel to the inner peripheral surface of the outer husking part can also be formed, and form a guide surface from the outside. The most upstream portion in the rotation direction of the surface 29 is a protrusion 51 protruding outward along a direction substantially perpendicular to the outer guide surface 29 , that is, along a radial direction. Such as Figure 16 , Figure 17 As shown, this protrusion 51 is formed in the state which spans the whole area of ​​the...

Abstract

The problem to be solved by the present invention is to seek the improvement of the husking rate of the impeller type rice husking device. The rice husking device has: a rice supply part (7), which discharges the rice brought in from the outside radially outward; and an impeller part (6), which is arranged along the outer periphery of the rice supply part (7), and passes The rotation guides the rice discharged from the rice supply part (7) radially outward, and the impeller part (6) is provided with: a plurality of blade bodies (14) radially extending toward the radially outward side; Part (21), located at the respective radially outer side positions of a plurality of blade bodies (14), receives paddy and performs shelling by collision, and the paddy shelling device also has: an outer shelling portion (9), which is set to It surrounds the outer periphery of the impeller part (6), receives the paddy thrown by the impeller part (6), and performs husking by collision.

Description

technical field [0001] The invention relates to an impeller type paddy hulling device. Background technique [0002] The periphery of the impeller portion of the impeller type paddy hulling device is covered by the shell, and is provided with a lining ring for shelling such as made of soft materials such as urethane, so as to surround the outer periphery of the impeller portion on the shell, so that the impeller portion The guided paddy collides with the lining ring, so that the husking process of separating the paddy into paddy husk and brown rice is performed through the lining ring. That is to say, the paddy is received by the blade body by the rotation of the impeller and is guided radially outward by centrifugal force, and is thrown outward from the radially outer end of the blade body so that it collides with the bushing. Shelling treatment (for example, refer to Patent Document 1). [0003] In the above-mentioned prior art solution, when the rice is thrown outward f...
