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 the radial direction. Such as Figure 16 , Figure 17 As shown, this protrusion 51 is formed in the state which spans the whole area of ​​t...

Abstract

The invention aims to improve a husking rate of an impeller-type rice husking device. The rice husking device comprises a rice supply part (7) and an impeller part (6), wherein the rice supply part discharges externally transported rice outwards in the radial direction; and the impeller part is disposed along the peripheries of the rice supply part (7) and guides the rice discharged from the rice supply part (7) outwards along the radial direction through rotation. The impeller part (6) comprises multiple blade bodies (14) and multiple inner side husking parts (21), wherein the multiple blade bodies extend in a radial pattern towards the radial external side; and the multiple inner side husking parts are located on the radial external side parts of the multiple blade bodies (14) respectively, receive the rice and conduct husking through collision. The rice husking device also comprises an external side husking part (9) which is set to surround the peripheries of the impeller part (6), receive the rice thrown by the impeller part (6) and carry out the husking through the 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...
