Description

Technical Field

[0001] This application relates to the field of sand roller rice milling machine technology, and in particular to a chaff removal device for sand roller rice milling machine. Background Technology

[0002] After harvesting, rice grains need to have their seed coats removed to become edible rice grains. Generally, this process requires the use of a rice milling machine. The chaff removal mechanism of a traditional vertical sand roller rice milling machine includes components such as an air spray net, a chaff removal chamber, and a chaff removal fan.

[0003] The authorized patent application CN202022163900.1 discloses a rice bran removal device for a sand roller rice mill, belonging to the field of agricultural implements technology. It includes a housing with legs on both sides of the lower end and a rice bran outlet at the middle of the lower end. A sieve cylinder is installed inside the housing. This invention improves the separation of rice and rice bran by setting a rotating shaft and installing three sieves on it. Material is poured into the sieve cylinder through the feed inlet and filtered through the three sieves, resulting in better separation of rice and rice bran. Furthermore, the rotating shaft has several air outlets. When the device is working, a motor drives a fan, and the airflow enters the rotating shaft through a collector and then blows the rice bran on the sieves through the air outlets. The rice bran is blown out of the sieve cylinder and discharged from the rice bran outlet, improving the separation effect of rice and rice bran and enhancing the working quality and efficiency of the device.

[0004] However, in the aforementioned patent, rice bran is filtered by setting up an integral sieve cylinder, which blows the rice bran out of the sieve cylinder and discharges from the rice bran outlet. This makes subsequent cleaning and maintenance inconvenient, as the entire sieve cylinder needs to be disassembled for cleaning. Moreover, when one part of the sieve cylinder is damaged, the entire sieve cylinder needs to be replaced, thus increasing the cost of use. Utility Model Content

[0005] To address the problem that existing rice bran removal devices for sand roller rice mills filter rice bran using an integral sieve cylinder, causing the bran to be blown out of the sieve cylinder and discharged from the bran outlet, which leads to inconvenience in later cleaning and maintenance, requiring the entire sieve cylinder to be disassembled for cleaning, and requiring the replacement of the entire sieve cylinder when one part is damaged, thus increasing the cost of use, this application provides a rice bran removal device for sand roller rice mills.

[0006] The present application provides a chaff removal device for a sand roller rice milling machine, which adopts the following technical solution:

[0007] A bran-removing device for a sand roller rice milling machine includes a base and a processing housing mounted on top of the base. A discharge chamber is provided below the processing housing, and funnels symmetrically connected to it are installed above it. A rotating shaft is installed in the center of the processing housing, and screening hoppers are installed at equal intervals on the outer side of the rotating shaft. Several air outlets are symmetrically provided above each screening hopper. A drive housing is installed in the center above each screening hopper. The drive housing contains a rotating assembly for driving the rotating shaft and a blower mechanism connected to the air outlets. A baffle is fixedly installed above each screening hopper, and mounting holes are provided around the baffle. Filtering mechanisms for filtering and removing bran are detachably installed in each mounting hole.

[0008] Preferably, the discharge chamber contains a collection box for recycling rice. The collection box has an inlet at the top, several rollers at the bottom, and a handle fixedly installed on the outside.

[0009] Preferably, the filtration mechanism includes a mounting frame that is detachably installed in the mounting hole and a filter screen fixed in the mounting frame.

[0010] Preferably, the mounting frame has symmetrical sliding cavities at both ends, a sliding rod is fixedly installed in the middle of the sliding cavity, a sliding plate and a spring are slidably sleeved on the outside of the sliding rod, one end of the spring is connected to the sliding plate, both ends of the sliding plate are slidably connected to the sliding cavity, and a limit block is symmetrically installed on one side. Limiting holes matching the limit blocks are symmetrically opened on the upper and lower sides of the mounting hole.

[0011] Preferably, a through hole is provided on the outer side of the sliding cavity, and a lever is slidably installed inside the through hole. One end of the lever passes through the sliding cavity and is fixedly connected to the sliding plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The rice milling machine uses a bran removal device that filters the rice by installing a filter mechanism around the baffle. When the filter mechanism at one of the mounting holes is damaged, only that one part needs to be replaced, without having to disassemble the entire machine for replacement, which reduces the cost of use. In addition, the filter mechanism is easy to install and remove, which makes it convenient for later replacement, cleaning and maintenance. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution:

[0022] A rice milling machine with a sand roller for removing chaff includes a base 1 and a processing housing 2 installed on top of the base 1. A discharge chamber 4 is provided below the processing housing 2, and funnels 3 connected to it are symmetrically installed above it. A rotating shaft 5 is installed in the middle of the processing housing 2. Screening hoppers 7 are installed at equal intervals on the outside of the rotating shaft 5. Several air outlets 6 are symmetrically provided above the screening hoppers 7. A drive box 8 is installed in the middle above the screening hoppers 7. A rotating component for driving the rotating shaft 5 and a blower mechanism connected to the air outlets 6 are installed inside the drive box 8. A baffle 9 is fixedly installed above the screening hoppers 7. Mounting holes 10 are provided around the baffle 9. A filter mechanism for filtering and removing chaff is detachably installed in each mounting hole 10.

[0023] During operation, the material is poured into the screening hopper 7 inside the processing housing 2 through the funnel 3. The rotating component is started, driving the rotating shaft 5 to rotate. The screening hopper 7 on the rotating shaft 5 rotates to screen the material. Through multiple screening hoppers 7, the screening effect of rice and rice bran is improved. At the same time, the blower mechanism is started, blowing the rice bran on the screening hopper through the air outlet 6 on the rotating shaft 5. The rice bran is blown out of the screen cylinder 9 and filtered by the filter mechanism on the baffle 9, so that the rice bran is discharged outside the processing housing 2. This improves the separation effect of rice and rice bran. By installing filter mechanisms on all four sides of the baffle 9, when the filter mechanism at one installation hole is damaged, only that one part needs to be replaced, without the need for complete disassembly and replacement, thus reducing the cost of use.

[0024] It should be noted that the rotating component and the blower mechanism described here are existing technologies and will not be elaborated further. For the specific working principle, please refer to the authorized patent with application number CN202022163900.1.

[0025] The discharge chamber 4 contains a collection box 11 for recycling rice. The collection box 11 has an inlet at the top, several rollers at the bottom, and a handle fixedly installed on the outside. It should be noted that the collection box 11 is divided into a first collection chamber and a second collection chamber by a partition. The second collection chamber is located outside the first collection chamber. Thus, the screened rice can be recycled through the first collection chamber, and the rice bran can be recycled through the second collection chamber, achieving the purpose of classified recycling and making it convenient to remove rice and rice bran.

[0026] The filtration mechanism includes a mounting frame 12 that is detachably installed in the mounting hole 10 and a filter screen 13 fixed in the mounting frame 12.

[0027] The mounting frame 12 has symmetrical sliding cavities at both ends. A slide rod 14 is fixedly installed in the middle of the sliding cavity. A slide plate 15 and a spring are slidably sleeved on the outside of the slide rod 14. One end of the spring is connected to the slide plate 15. Both ends of the slide plate 15 are slidably connected to the sliding cavity. A limit block 16 is symmetrically installed on one side. Limiting holes matching the limit block 16 are symmetrically opened on the upper and lower sides of the mounting hole.

[0028] A through hole is provided on the outer side of the sliding cavity, and a lever 17 is slidably installed inside the through hole. One end of the lever 17 passes through the sliding cavity and is fixedly connected to the slide plate 15.

[0029] During installation, first press the lever 17 towards the filter screen, causing the lever 17 to move the slide plate 15 towards the inside of the adjustment chamber, so that the limiting block 16 can retract into the mounting frame 12. Then, insert the entire mounting frame 12 into the mounting hole 10 in the baffle 9, ensuring that the limiting block 16 corresponds to the position of the limiting hole. Then release the lever 17, thereby causing the limiting block 16 to be inserted into the limiting hole respectively, achieving a locking and fixing. This facilitates the overall installation and disassembly of the filter mechanism, thus providing convenience for later replacement, cleaning, and maintenance.
