The utility model discloses a change the appearance of rice knife, the working face of rice knife adopts convex design, and its radian carries out optimal design according to the surface radian of sand roller to increase the area of contact of the grain of rice, become the face contact by the line contact, improve work efficiency.

Description

Rice knife structure of vertical rice machine

Technical Field

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

Background

In the grain processing process of the vertical rice mill, brown rice enters a material distributing groove at the top of the rice mill 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 rice knife of the existing vertical rice mill is shaped like a square strip or a rectangular strip with hardness as shown in fig. 1-2, while the sand roller is a disc, and rice grains are contacted between the sand roller and the disc through a line. In this case, the pressure of the rice cutter must be increased to increase the cutting force in order to achieve a good rice milling effect, but broken rice is easily generated in the rice milling process.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a rice knife structure of vertical rice machine 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: the utility model provides a rice knife structure of vertical rice machine, includes rice knife, the one side definition that rice knife is close to the emery roll is the working face, the working face is the circular arc face of indent.

The further arrangement is that 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 discloses a change the appearance of rice knife, the working face of rice knife adopts convex design, and its radian carries out optimal design according to the surface radian of sand roller to increase the area of contact of the grain of rice, become the face contact by the line contact, improve work efficiency.

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 rice knife structure of a vertical rice mill is shown in figures 3-7, when the vertical rice mill works, brown rice firstly enters a material distributing groove 2 at the top of the vertical rice mill, and then enters a rice milling cavity provided with an abrasive roller 4 through the material distributing groove 2 via a spiral head 3, and a rice knife 1 in the embodiment is vertically arranged in the rice milling cavity and is in clearance fit with the abrasive roller 4 for milling the brown rice.

The main invention of the embodiment is that the working surface 11 of the rice knife 1 close to the sand roller 4 is a concave arc surface, and the radian of the arc surface is matched with the radian of the surface of the sand roller 4, so that when the sand roller 4 is driven by the main shaft 5 to rotate, the gap between the rice knife 1 and the sand roller 4 is always kept constant, rice grains are closer to surface contact between the rice knife 1 and the sand roller 4, the contact area of the rice grains is increased, and the processing efficiency is improved.

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.

Claims (2)

1. The utility model provides a rice knife structure of vertical rice machine, includes rice knife, the one side definition that rice knife is close to the emery roll is the working face, its characterized in that, the working face is the circular arc face of indent.

2. The rice knife structure of vertical rice mill according to claim 1, characterized in that the radian of the circular arc surface matches the radian of the sand roller surface.
