Description

Technical Field

[0001] The utility model relates to the field of rice processing equipment, in particular to a rice hulling device. Background Art

[0002] Rice refers to the seeds without husks removed. Botanically, it belongs to the subspecies of Oryza sativa in the subgenus Oryza of the genus Oryza in the family Gramineae. When the rice is beaten off the rice stalks, the husks and impurities on the rice need to be removed to facilitate the subsequent use of the rice.

[0003] The rice huller is a device for separating rice from rice husks. The rice is squeezed out of the husks by symmetrically arranged rice hulling rollers, and the rice is husked out after multiple hullings. Figure 2 As shown, a supporting connecting rod for improving stability is arranged in the rice hulling device body. When hulling rice, rice husks and rice are easily accumulated on the supporting connecting rod, which affects the overall rice hulling effect. Utility Model Content

Detailed Embodiments

[0024] The following describes the implementation modes of the present utility model through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through different specific implementation modes. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0025] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components during actual implementation. The type, quantity, and ratio of each component during actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0026] As Figures 1 to 4 shown, a rice hulling device includes a rice hulling device body 1. A rice hulling roller mechanism is arranged inside the rice hulling device body 1, and a support connecting rod 16 is arranged below the rice hulling roller mechanism. The cross-section of the support connecting rod 16 is in an I shape. A groove 18 is arranged at the top of the support connecting rod 16, and a convex block 20 is placed in the groove 18. The surface of the convex block 20 facing the rice hulling roller is triangular.

[0027] The purpose of such a design is to change the original concave surface to a convex surface by arranging a groove and a convex block on the existing support connecting rod, so that rice and rice husks are not easily accumulated therein, thereby avoiding the phenomenon that the overall rice hulling effect is poor due to the rice and rice husks accumulated on the support connecting rod after multiple rice hulling operations.

[0028] In this embodiment, a specific structure of the support connecting rod is provided. A perforation 19 is arranged in the groove 18, and the bottom of the convex block 20 is detachably connected to the support connecting rod 16 through a connecting bolt 21 passing through the perforation 19.

[0029] The purpose of such a design is that during installation, first place the convex block in the groove of the support connecting rod, and then detachably connect the convex block to the support connecting rod through the connecting bolt passing through the perforation.

[0030] It should be pointed out that during actual use, since the support connecting rod is used to stabilize the rice hulling cavity inside the entire rice hulling device body, it is not easy to directly cut it off. Therefore, on the existing I-shaped structure, perforations are drilled through a drill, so that the convex block is easy to install on it. In this way, the rice and rice husks falling from the rice hulling roller mechanism above will fall along the inclined surface of the convex block and are not easily accumulated on the support connecting rod.

[0031] In this embodiment, a feed inlet is provided at the top of the rice hulling device body 1, and a discharge outlet 8 is provided at the bottom of the rice hulling device body 1.

[0032] At the same time, the rice hulling roller mechanism includes a first rice hulling roller mechanism and a second rice hulling roller mechanism.

[0033] Furthermore, in a specific implementation, the first rice hulling roller mechanism includes a first motor 2, a first belt 4, a first outer turntable 6, a first inner rotating shaft 10, a first rice hulling roller 11, and a first outer sleeve 12;

[0034] The first motor 2, the first belt 4, and the first outer turntable 6 are arranged outside the rice hulling device body 1, and the power output end of the first motor 2 drives the first outer turntable 6 to rotate through the first belt 4;

[0035] The first inner rotating shaft 10, the first rice hulling roller 11, and the first outer sleeve 12 are arranged inside the rice hulling device body 1. The first inner rotating shaft 10 is centrally connected to the first outer turntable 6, and the first inner rotating shaft 10 passes through the center of the first rice hulling roller 11 and can drive the first rice hulling roller 11 to rotate;

[0036] The first outer sleeve 12 is sleeved on the outer periphery of the first rice hulling roller 11.

[0037] Moreover, the second rice hulling roller mechanism includes a second motor 3, a second belt 5, a second outer turntable 7, a second inner rotating shaft 13, a second rice hulling roller 14, and a second outer sleeve 15;

[0038] The second motor 3, the second belt 5, and the second outer turntable 7 are arranged outside the rice hulling device body 1, and the power output end of the second motor 3 drives the second outer turntable 7 to rotate through the second belt 5;

[0039] The second inner rotating shaft 13, the second rice hulling roller 14, and the second outer sleeve 15 are arranged inside the rice hulling device body 1. The second inner rotating shaft 13 is centrally connected to the second outer turntable 7, and the second inner rotating shaft 13 passes through the center of the second rice hulling roller 14 and can drive the second rice hulling roller 14 to rotate;

[0040] The second outer sleeve 15 is sleeved on the outer periphery of the second rice hulling roller 14, and rice grains can pass between the first outer sleeve 12 and the second outer sleeve 15.

[0041] The purpose of such a design is that the first motor and the second motor can drive the two rice hulling rollers to rotate in opposite directions, so as to extrude and remove the paddy and rice passing between the two rice hulling rollers.

[0042] It should be noted that according to the types of paddy actually processed, outer sleeves of different sizes can be selected to change the distance between the first rice hulling roller mechanism and the second rice hulling roller mechanism.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
