Abstract

The utility model relates to a grain processing machinery technical field for brown rice whitening specifically discloses a vertical rice mill of many rice knives, from the top down includes branch silo, spiral head and husk rice chamber in proper order, the husk rice intracavity is equipped with rice sieve piece and rotatable emery roll, the husk rice intracavity still is equipped with 6-10 the rice knife of vertical setting, the rice knife along emery roll circumference evenly distributed and with emery roll clearance fit. The utility model increases the number of the rice knives, so that the clearance adjusting parameters of the rice knives and the grinding roller are more changeable, and the amplitude of the pressure adjusting pressure can be larger; the distance between different rice knives and the sand roller is changed through adjustment, so that the softness is improved, the pressure in the rice mill is reduced, and the contact surface is increased by breaking the motion track of rice grains for multiple times. Therefore, the rice grains are relatively mild in acting force in the rice milling chamber, and are not easy to break in the rice milling process.

Description

Vertical rice machine with multiple rice knives

Technical Field

The utility model relates to a grain processing machinery technical field for brown rice whitening, concretely relates to vertical rice machine of many rice knives.

Background

The brown rice enters a material distributing groove at the top of the rice machine through a fixed pipeline and is distributed by the material distributing groove to enter the spiral head and the sand roller. After the brown rice enters the grinding roller, the brown rice is rubbed with the sieve sheet by a certain distance controlled by the rice knife. The existing vertical rice mill is controlled by 2 or 4 rice cutters, the range of pressure regulation is smaller, the linear speed ratio of the grinding roller of the vertical rice mill is faster, the acting force of rice grains on a rice milling chamber is more direct, the rice milling process is easy to break, and the vertical rice mill is not suitable for milling high-precision rice.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a vertical rice machine of many rice knives aims at solving the problem among the prior art that above-mentioned background art provided.

The above technical problem of the present invention can be solved by the following technical solutions: a multi-cutter vertical rice mill sequentially comprises a material distributing groove, a screw head and a rice milling cavity from top to bottom, wherein a rice sieve sheet and a rotatable sand roller are arranged in the rice milling cavity, 6-10 vertically arranged rice cutters are further arranged in the rice milling cavity, and the rice cutters are uniformly distributed along the circumferential direction of the sand roller and are in clearance fit with the sand roller.

Preferably, the number of the rice knives is 8.

Preferably, the side wall of the rice milling cavity is vertically provided with an upright post, a rice knife pad is vertically and fixedly arranged on the upright post, and the rice knife is fixedly arranged on the rice knife pad.

Furthermore, one surface of the rice knife close to the sand roller is an inwards concave circular arc surface.

Further, the radian of the arc surface is matched with the radian of the surface of the sand roller.

Compared with the prior art, the utility model, its beneficial effect lies in: the utility model increases the number of the rice knives, so that the clearance adjusting parameters of the rice knives and the grinding roller are more changeable, and the amplitude of the pressure adjusting pressure can be larger; the distance between different rice knives and the sand roller is changed through adjustment, so that the softness is improved, the pressure in the rice mill is reduced, and the contact surface is increased by breaking the motion track of rice grains for multiple times. Therefore, the rice grains are relatively mild in acting force in the rice milling chamber, and are not easy to break in the rice milling process.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example (b): a multi-knife vertical rice mill, as shown in figures 1-5, comprises a material separating groove 2, a screw head 3 and a rice milling cavity from top to bottom in sequence, wherein a rice sieve sheet 8 and a sand roller 4 are arranged in the rice milling cavity, and the sand roller 4 can be driven by a main shaft 5 to rotate. In the embodiment, the rice milling cavity is also internally provided with 8 vertically arranged rice cutters 1 which are uniformly distributed along the circumferential direction of the sand roller 4 and are in clearance fit with the sand roller 4.

In the structure, the side wall of the rice milling cavity is vertically provided with 8 upright posts 6, a rice knife pad 7 is vertically and fixedly arranged on each upright post 6, and the rice knives 1 are respectively and fixedly arranged on the rice knife pad 7.

In the specific implementation of the embodiment, the brown rice firstly enters the distributing groove 2 at the top of the vertical rice mill, then enters the rice milling cavity from the distributing groove 2 through the spiral head 3, and is milled by the cooperation of the rice knife 1 and the sand roller 2. In the embodiment, by increasing the number of the rice knives 1, the gap adjusting parameters of the rice knives 1 and the sand rollers 4 are more variable, and the amplitude of the pressure adjusting pressure can be larger; the distance between different rice knives 1 and the sand roller 4 is changed through adjustment so as to improve the softness, reduce the pressure in the rice mill, and increase the contact surface by breaking the motion track of rice grains for many times. Therefore, the rice grains are relatively mild in acting force in the rice milling chamber, and are not easy to break in the rice milling process.

In addition, this embodiment has still improved the shape of rice knife, as shown in fig. 4-5, the working face 11 that rice knife 1 is close to sand roller 4 is the circular arc surface of indent, and the radian of this circular arc surface matches with the radian on sand roller 4 surface for when sand roller 4 rotated under the drive of main shaft 5, the clearance of rice knife 1 and sand roller 4 remains invariable throughout, thereby make the rice grain more be close to the face contact between rice knife 1 and sand roller 4, increased the area of contact of rice grain, thereby improve machining efficiency.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. All changes and modifications that may be made by the technical spirit of the present invention to the above embodiments by simple modification are considered to fall within the scope of the present invention.
