Problems solved by technology

[0003] According to the device form of the sticky roller spindle of the rice mill, the rice mill is divided into two categories: vertical rice mill and horizontal rice mill. Most of the vertical rice mills are sand white rice mills, which belong to the milling type. The whitening rollers are assembled in series with grinding wheels, and the vertical whitening is a natural vertical falling method. The whitening rollers have been subjected to inter-granular friction and impact for a long time, causing small errors in the verticality of the whitening roller axis. Although the whitening rollers are still completely balanced, but Its center of gravity also deviates from the plumb line to produce unbalanced force, resulting in too low pressure in the whitening chamber, resulting in reduced output

Embodiment 1

[0029] Such as Figure 1-Figure 3 As shown, the present invention provides a rice mill for agricultural machinery, its structure includes a base 1, a baffle plate 2, a motor 3, a whitening chamber 4, a feed hopper 5, and a discharge port 6, and the base 1 is welded with The baffle plate 2, the baffle plate 2 is used as the outer protective cover of the motor 3, the transmission belt of the motor 3 adopts transmission cooperation with the transmission end of the whitening chamber 4, and the bottom of the whitening chamber 4 is provided with a discharge port 6, in which The adjacent side of the same position of the discharge port 6 is provided with a bran outlet, and a feed hopper 5 is installed on the top of the whitening chamber 4, and a rice sieve 41, a whitening roller 42, a transmission Shaft 43, the rice sieve 41 is located at the interface between the whitening chamber 4 and the feed hopper 5, the rice sieve 41 is fitted on the vertical upper end of the whitening roller 4...

Embodiment 2

[0033] Such as Figure 4 As shown, the whitening roller 42 is spliced ​​by more than two tile-shaped parts of the same structure, and is divided into upper and lower parts, wherein the upper part has a cutting sheet 421, and the lower part has a friction sheet 422. The cutting sheet The upper end of the 421 is fixed with a conical pressure cap 423, and the friction plate 422 and the cutting plate 421 are fixed with an extension rod 424. The cutting plate 421 is mainly composed of an emery roller, and the friction plate 422 is placed on the surface of the iron roller to realize The effective operation of the cutting sheet 421 and the friction sheet 422, by improving the structure of the whitening roller 42, is spliced ​​with several tile-shaped parts to form upper and lower parts. The upper part is installed as a grinding type, and the lower part is installed as a friction type. The type of whitening roller 42 can be determined according to the original like this, and the press...

Embodiment 3

[0035] Such as Figure 5-Figure 8 As shown, the rice sieve 41 is suspended by the swing rod 411 and the return spring 412, the outer surface of the friction plate 422 is an inner ring a1 in the shape of an abacus, and the inner ring a1 is matched with the outer ring a2. The outer ring a2 is set at the lower end of the rice sieve 41, and is controlled by a return spring 412, and the swinging pull rod 411 is located on the upper top of the return spring 412. The rice sieve 41 is hexagonal and is located in the whitening chamber 4 in a circumferential pressure. There are six gentle changes in the whitening roller 42. At the end of the whitening roller 42 (that is, the position of the friction plate 422), the inner ring a1 in the shape of an abacus is matched with the outer ring a2 controlled by the return spring 412. When the pressure in the whitening chamber When it is not too large, the tension of the return spring 412 moves the rice sieve 41 up, so that there is almost no gap ...

Abstract

The invention discloses a rice husking machine for agricultural machinery. The rice husking machine structurally comprises a base, a baffle plate, a motor, a whitening chamber, a feeding hopper and adischarge hole, wherein the baffle plate is welded with the base; the baffle plate functions as an outer protection cover of the motor; the conveyer belt of the motor is in transmission cooperation with the transmission end of the whitening chamber; the discharge hole is formed in the bottom of the whitening chamber; a bran outlet is formed in an adjacent side in a same position of the discharge hole; the feeding hopper is mounted at the top end of the whitening chamber; the whitening chamber is internally provided with a rice screen, a whitening roller and a transmission shaft; the rice screen is arranged at the interface of the whitening chamber and the feeding hopper; and the rice screen cooperates with the vertical upper end of the whitening roller. Both the rice screen and the whitening roller are mounted inside the whitening chamber, the rice screen is suspended with a swinging pull rod through a return spring and can be moved up and down, in addition, the pressure of the whitening chamber can be controlled by adjusting the tension degree of the return spring, the pressure in the whitening chamber can be kept constant, a function of automatic pressure adjustment is achieved,and the situation that the output is reduced as the pressure inside the whitening chamber is too small can be avoided.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a rice mill for agricultural machinery. Background technique [0002] Rice milling machine is a kind of agricultural processing machinery. It is used to remove the bran layer from brown rice and grind it into white rice. After removing the bran layer in the whitening chamber, it is discharged from the rice outlet, and the rice bran is discharged through the rice sieve holes. The feeding amount of the feeding mechanism, the gap between the whitening chamber and the pressure can be adjusted, and different hole shapes and sizes can be used. The size of the rice sieve is adapted to different needs. The rice outlet is equipped with a pressure door or a gate to control the size of the rice outlet and can be adjusted to obtain different milling precision and flow. Simply put, the rice milling is subject to The mechanical and physical effects are various and intersecting. The long-...
