Description

Technical Field

[0001] The invention relates to the field of rice processing, and more particularly to rice processing equipment and a rice processing method. Background Art

[0002] Rice is a finished product made from paddy rice after processes such as cleaning, husking, milling and finishing. The rice processing process is the process of removing the husk (lemma) and cortex (bran layer) of rice. Rice grains are composed of husk, cortex, embryo and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the minimum degree of crushing to make rice with better edible quality. There are many rice processing equipments at present. However, the broken rice produced in the processing equipment is generally separated uniformly. When too much rice is separated at the same time, the separation time will be too long. When too little rice is separated, the processing time will be affected, and then the finished rice sold will contain more or less broken rice, resulting in poor appearance. Summary of the invention

[0003] The invention provides a rice processing device and a rice processing method, aiming to utilize the interval time when rice is packaged to separate broken rice and improve the quality of finished rice.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A processing method used in rice processing equipment comprises the following steps:

[0006] Step 1: Place each portion of rice for packaging into the feeding chute;

[0007] Step 2: Drive the shaft to rotate 50 degrees and drive the fan to work to clean the dust in the rice;

[0008] Step 3: The driving motor rotates to drive the baffle frame to rotate 180 degrees to screen the rice for the second time;

[0009] Step 4: Drive the shaft to rotate 100° to pack the rice at the discharge chute, and repeat step 1 at the same time;

[0010] Step 5. Repeat steps 3 and 4.

[0011] A rice processing device comprises a bracket, one side of the bracket is connected to a feed chute by screws, the lower part of the feed chute on the bracket is connected to a discharge chute by screws, a screen barrel is provided on the bracket, a plurality of fine holes are provided on the screen barrel, three baffle frames are provided in the screen barrel, a plurality of arc-shaped baffles are fixed on each baffle frame by screws, and the arc-shaped baffles on every two adjacent baffle frames are arranged alternately.

[0012] The lower end of each arc-shaped baffle is in contact with the inner surface of the screen barrel, and the inner surface below the arc-shaped baffle is tangent to the inner surface of the screen barrel.

[0013] The rotating shaft is rotatably connected to the bracket, a rotating frame is welded on the rotating shaft, the screen barrel is welded on the rotating frame, and each baffle frame is rotatably connected to the rotating frame.

[0014] The beneficial effects of the rice processing equipment and the rice processing method of the present invention are:

[0015] The quantitative rice in each package is slid from the feed chute into the screen barrel. As the screen barrel tilts, the rice slides from one side of the screen barrel to the other side, and the fine holes on the screen barrel can separate the broken rice in the rice. At the same time, the baffle prevents the rice from sliding, and then turns it over to make it easier to sifting. When the screen barrel rotates, it can also shake to further increase the screening effect. Each time the rice is packaged, the rice at the discharge chute is packaged, and the steps are repeated, so a small amount of rice is sieved during the packaging process, thereby ensuring the separation effect of broken rice in the finished rice and improving product quality.

DETAILED DESCRIPTION

[0026] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] like Figures 2 to 4 , to solve the problem of screening broken rice.

[0029] A rice processing device includes a bracket 14, a feed chute 404 fixed to one side of the bracket 14 by screws, a discharge chute 405 fixed to the bracket 14 by screws and located below the feed chute 404, a screen barrel 11 arranged inside the bracket 14, the screen barrel 11 is provided with a plurality of fine holes, three baffle frames 12 are arranged inside the screen barrel 11, each baffle frame 12 is welded with a plurality of arc baffles 201, and the arc baffles 201 on every two adjacent baffle frames 12 are arranged alternately.

[0030] First, each package of rice is placed on the feeding chute 404. Due to the effect of gravity, the rice slides along the feeding chute 404 to one end of the screen barrel 11. Then, the screen barrel 11 is driven to rotate, so that the rice slides from one end of the screen barrel 11 to the other end due to the effect of gravity. Then, the rice passes through the fine holes on the screen barrel 11, so that broken rice falls from the fine holes, and the whole rice slides to the tail of the screen barrel 11. At the same time, during the sliding process of the rice, it hits the arc-shaped baffle 201 on the baffle frame 12, thereby realizing the function of turning the rice. Multiple alternating arc-shaped baffles 201 can prevent the rice from being blocked while ensuring the turning effect of the rice. When the rice slides to the tail of the screen barrel 11, the baffle frame 12 is driven to rotate, thereby driving the arc-shaped baffle 201 to rotate, so that its opening direction changes. The rear drive screen barrel 11 rotates in the opposite direction, and the rice slides from the tail of the screen barrel 11 to the front end again. At the same time, the arc baffle 201 flips it again, and the rice is screened for the second time. Thereafter, the rice slides along the front end of the screen barrel 11 to the discharge chute 405. The end of the discharge chute 405 is connected to the rice packaging device, and the rice can slide along the discharge chute 405 for packaging. During the rice packaging process, a new portion of rice is repeatedly added to the feed chute 404, and the function of screening broken rice is added during the rice packaging process. The rice weight is small during screening, and the screening effect is guaranteed. The present invention performs screening during the packaging process, which will not affect the processing time of the rice. At the same time, the device mainly relies on the gravity of the rice itself for screening, and performs screening with minimal energy consumption, which is both energy-saving and time-saving.

[0031] like Figure 3 , to ensure the turning effect of the arc baffle 201 on the rice.

[0032] The lower end of the arc-shaped baffle plate 201 contacts the inner side of the sieve barrel 11 , and the inner surface of the arc-shaped baffle plate 201 is tangent to the inner surface of the sieve barrel 11 .

[0033] When the rice slides along the sieve barrel 11, in order to prevent the arc baffle 201 from getting stuck in the rice and affecting its movement, the arc baffle 201 is configured to be gradually thickened from the part in contact with the sieve barrel 11 upwards, so that the inner surface of the arc baffle 201 can be connected to the inner surface of the sieve barrel 11 to form a surface, so that the rice can easily slide along the arc baffle 201 to achieve the purpose of stirring, while avoiding the arc baffle 201 that is too thick from getting stuck in the rice.

[0034] like Figure 4 and Figure 5 , in order to solve the problem of rotation of the screen barrel 11 and the baffle frame 12.

[0035] The rotating shaft 13 is rotatably connected to the bracket 14 , the rotating frame 301 is welded to the rotating shaft 13 , the screen barrel 11 is fixed to the rotating frame 301 by screws, and each baffle frame 12 is rotatably connected to the rotating frame 301 .

[0036] A driving motor is fixedly connected to the bracket 14, and the output shaft of the driving motor is connected to the rotating shaft 13 by transmission. The driving motor is driven to work, thereby driving the rotating shaft 13 to rotate, thereby driving the rotating frame 301 to rotate, and thereby driving the screen barrel 11 to rotate. At the same time, during the rotation of the rotating frame 301, the baffle frame 12 is driven to rotate synchronously with the screen barrel 11 to avoid collision.

[0037] like Figure 3 and Figure 4 , to solve the problem of baffle frame 12 rotating.

[0038] A gear 202 is welded on each baffle frame 12 , and two adjacent gears 202 are meshed with each other. A motor 303 is fixed on the rotating shaft 13 , and a belt 304 is provided on the output shaft of the motor 303 . The other end of the belt 304 is connected to the rotation center of a baffle frame 12 .

[0039] The driving motor 303 rotates, and then drives a gear 202 to rotate through the belt 304, and then drives the baffle frame 12 to rotate. At the same time, through the meshing between the gears 202, multiple baffle frames 12 rotate at the same time, and then drive the arc baffle 201 to rotate and change direction.

[0040] like Figure 4 , in order to solve the problem of the arc baffle 201 on the rice turning efficiency.

[0041] The included angle between the baffle frame 12 in the middle and the baffle frames 12 on both sides is 10 degrees, and the distance between two adjacent baffle frames 12 is equal to the rotation radius of the baffle frame 12 .

[0042] When the distance between the baffle frames 12 is too large, during the movement of rice, the screen barrel 11 is cylindrical, which will cause the rice to gather in the middle, resulting in uneven turning of the rice on both sides. Therefore, the distance between adjacent baffle frames 12 is set to the rotation radius of the baffle frame 12. At the same time, in order to avoid mutual influence between multiple baffle frames 12 during rotation, the angle between the middle baffle frame 12 and the baffle frames 12 on both sides is set to 10 degrees, so as to avoid mutual jamming during rotation.

[0043] like Figure 5 and Figure 6 , to increase the screening effect of rice.

[0044] The two fixing blocks 401 are respectively welded on the left and right sides of the bracket 14, and multiple push rods 402 are welded on each fixing block 401. The two spline teeth 302 are respectively welded on the two ends of the rotating shaft 13, and each push rod 402 is in contact with the corresponding spline tooth 302. A spring 403 is fixedly connected between each fixing block 401 and the rotating shaft 13.

[0045] When the rice moves on the sieve barrel 11, when it contacts the arc baffle 201, it is easily blocked by the arc baffle 201, and then the spline teeth 302 are driven to rotate when the rotating shaft 13 rotates, and the springs 403 on both sides are always in an extended state, thereby pushing the spline teeth 302 to be in close contact with the corresponding multiple push rods 402, and then when the push rods 402 contact the recesses on the spline teeth 302, the rotating shaft 13 moves to one side of the corresponding fixed block 401. Similarly, when the push rods 402 contact the protrusions on the spline teeth 302, the rotating shaft 13 is pushed to move to the other side. Through the alternating cooperation between the push rods 402 on both sides and the spline teeth 302, the rotating shaft 13 rotates, and then it swings left and right while rotating, thereby increasing the effect of rice screening, and at the same time avoiding the rice being blocked by the arc baffle 201 and affecting its movement.

[0046] like Figure 7 and Fig. 9 , in order to solve the problem of cleaning lighter impurities such as dust in rice.

[0047] A tail plate 15 is welded to the other side of the bracket 14 , a filter screen is arranged on the tail plate 15 , and a fan 505 is arranged outside the filter screen.

[0048] When the sieve barrel 11 rotates, the rice moves to the tail plate 15, driving the fan 505 to work, thereby sucking air outward from the filter on the tail plate 15. The filter can block the rice, and then the lighter dust in the rice is sucked out from the filter, thereby achieving the purpose of cleaning the lighter impurities in the rice.

[0049] like Figure 7 and Figure 8 , to increase the cleaning effect of dust in rice.

[0050] A turntable 501 is rotatably connected to the tail plate 15, one end of a connecting rod 502 is rotatably connected to the turntable 501 at an eccentric position, the other end of the connecting rod 502 is fixedly connected to a stirring plate 504, a slide groove 503 is provided in the middle section of the connecting rod 502, and a protrusion is provided on the tail plate 15, which is slidably connected in the slide groove 503.

[0051] The drive turntable 501 rotates, thereby driving the other end of the connecting rod 502 to move. Since a slide groove 503 is provided on the connecting rod 502, the slide groove 503 moves along the protrusion on the tail plate 15, thereby causing the other end of the connecting rod 502 to reciprocate, thereby driving the stirring plate 504 to reciprocate, thereby stirring the rice located below, thereby increasing the dust removal effect on the rice.

[0052] like Fig. 9 , in order to solve the problem of rotation of the turntable 501.

[0053] The rotation center of the turntable 501 is connected to the motor output shaft of the fan 505 by a belt.

[0054] When the fan 505 is driven to work, and then when the motor in the fan 505 is working, the turntable 501 is driven to rotate through the belt, thereby cleaning the dust in the rice while driving the stirring plate 504 to stir the rice, thereby increasing the cleaning effect.

[0055] like Figure 1 , a processing method used by a rice processing device, comprising the following steps;

[0056] Step 1: Place a portion of rice to be packaged into the feed chute 404 and allow it to slide into the sieve barrel 11;

[0057] Step 2: driving the rotating shaft 13 to rotate 50° to sieve the broken rice in the rice, and driving the fan 505 to clean the dust in the rice;

[0058] Step 3, the driving motor 303 rotates to drive the baffle frame 12 to rotate 180°;

[0059] Step 4: drive the rotating shaft 13 to rotate 100°, screen the rice for a second time, pack the rice at the discharge chute 405, and repeat step 1;

[0060] Step 5. Repeat steps 3 and 4.
