Horizontal rice mill

Abstract

The invention discloses a horizontal rice husking machine which comprises a fan (8) which is communicated with a chaff gathering bucket (7). A feeding opening (1) is communicated with a top end above a thruster (10). A discharging opening (6) is positioned at a tail end below a rice husking chamber (31). The horizontal rice husking machine is characterized in that the length of an emery roller (11) is 1-1.6m and the outer diameter of the emery roller (11) is 0.15 to 0.35m. Spiral grooves (21) on the emery roller (11) are of structures which are identical in depth and width. A sieving plate (15) and a sieving frame (14) are of integral structures. A cushion bar (13) is fixed on a beam (12) through a welding bolt (20). With the horizontal rice husking machine, the outer diameter and the length of the emery roller are enlarged, and at the same time, size of the sieving plate and the sieving frame are enlarged, a volume of the rice husking chamber is improved, productivity is improved and expanded sieving and explosive sieving are avoided as the spiral grooves in the emery roller are of structures which are identical in depth and width. A countersink in the cushion bar is removed and replaced by the welding bolt so that the amount of incomplete rice is reduced.

Description

technical field [0001] The present invention relates to a kind of grain machinery, more specifically it is a kind of horizontal rice milling machine for brown rice processing. Background technique [0002] The horizontal rice milling machine for grinding the surface of brown rice is widely used in the grain machine industry and has a large market demand. [0003] The existing rice mill is supported by a frame, a main shaft crosses the frame, and a propeller and an emery roller are installed on the main shaft, which constitute the rotating part of the machine. A sieve plate and a sieve frame are installed outside the emery roller, and the The center of the rack is concentric with the center of the main shaft, and the space between the emery roller and the sieve plate forms a rice milling room, and the brown rice to be whitened enters the rice milling room through the propeller through the feeding port, and the brown rice rolls and squeezes in the rice milling room. Pressing,...

AI Technical Summary

Problems solved by technology

Existing horizontal rice milling machine has the following problems in use: 1. The output is small and cannot meet the production needs of large rice processing plants. The length of the emery roller of existing horizontal rice milling machine is shorter and the diameter is smaller. People preconceivedly believe that because the brown rice rolls and squeezes in the rice milling room, if the length of the emery roller is longer and the diameter is larger, the movement stroke of the brown rice in the rice milling room will increase, and broken rice will easily occur, and the broken rice The price is only half of the price of rice, so it will seriously affect the quality of rice. The design length of the existing emery roller is 0.8-1 meter, and there is no design exceeding 1 meter; ②.

The previous point of view is that brown rice enters the rice milling chamber, from the feed end to the discharge end, with the removal of the brown rice skin and the discharge of bran powder, the pressure in the rice milling chamber gradually decreases, so the spiral groove is made deep and wide. , then gradually decrease to shallow and narrow, but the facts prove that due to the decrease of the thrust of the discharge end, the pressure of the discharge end increases, and the phenomenon of drum sieve and burst sieve is easy to occur.

In addition, due to the large interval between the sieve frames at the feed end, it is also easy to drum sieve and burst sieve

③. The structure of the sieve frame is scattered, and the sieve plate is also assembled from multiple pieces, which is very inconvenient to assemble and disassemble. In some cases, the small piece of sieve plate can be partially replaced to save costs; ④. There are countersunk holes on the pads, which is easy to produce broken rice; And wind pressure can solve this problem, which will increase the cost
