Description

Technical Field

[0001] The utility model relates to the technical field of color sorters, in particular to a color sorter for rice processing. Background Art

[0002] Color sorter is a device that uses photoelectric detection technology to automatically sort out different-colored particles in granular materials according to the differences in the optical properties of the materials. Color sorters have a wide range of applications, among which rice screening is particularly prominent. When the color sorter screens rice, when the rice is fed into the color sorter, it is necessary to use the filtering device arranged in the feeding port of the color sorter to perform primary filtering on the rice, so as to filter out stones and other large impurities in the rice, so as to reduce the impact of stones and other large impurities on color sorting and improve the quality of color sorting.

[0003] Referring to the Chinese utility model patent with authorization announcement number CN216137270U, ​​a color sorter for rice processing is disclosed. It can be seen from the drawings of the utility model patent that the filter screen in the patent is arranged horizontally, and the large particles of impurities to be filtered out are retained above the filter screen. When the filter screen is disassembled to clean up all the large particles of impurities above it, due to the lack of protection on the four sides of the filter screen, the protection effect of the large particles of impurities only by the frame is poor, and the large particles of impurities that are not completely discharged on the filter screen are easy to fall into the main body of the color sorter, which is easy to affect the normal operation of the main body of the color sorter. Utility Model Content

[0004] The utility model aims to provide a color sorter for rice processing which is convenient for discharging filtered out materials, and effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A color sorter for rice processing comprises a color sorter body, a feed port arranged on the top of the color sorter body and a hopper arranged above the feed port, wherein the bottom end of the hopper is inserted into the feed port, an opening is arranged on one side of the hopper, and slots extending obliquely are arranged on the two inner side walls of the hopper, and the two slots are both connected with the opening, filter plates are slidably inserted in the two slots, a sealing plate is fixed on one side of the filter plate, the sealing plate can be fitted into the opening and seal the opening, a U-shaped plate is fixed on the top of the filter plate, the U-shaped plate and the sealing plate jointly form a barrier above the filter plate, and a clamping mechanism is provided on the side of the hopper, and the clamping mechanism is used to clamp the hopper and limit it in the opening.

[0007] It can be seen that the U-shaped plate above the filter plate and the blocking plate arranged on its side together form an enclosure, and then a groove-like structure is formed above the filter plate. The filtered large particles of impurities can be temporarily stored in the groove. When the filter plate is removed to clean the large particles of impurities, the enclosure can provide protection for the large particles of impurities from the four sides of the filter plate, preventing the impurities from rolling down from the side of the filter plate and falling into the color sorter body. Since the slot is arranged at an angle, the filter plate inserted therein is also arranged at an angle. Under the action of gravity, the filtered large particles of impurities will roll down along the filter plate, so that the impurities can accumulate on one side of the filter plate, leaving other parts of the filter plate, and will not affect the normal filtration of rice.

[0008] Furthermore, when the filter plate is fully inserted into the slot, the three outer walls of the U-shaped plate are tightly slidably fitted with the three inner walls of the hopper.

[0009] Furthermore, the clamping mechanism includes a bracket, a clamping rod, a pinching handle and a second spring. The bracket is fixed to the side of the feeding hopper, and the bracket is provided with a through sliding hole. The clamping rod is inserted into the sliding hole through sliding, and the pinching handle is fixed to one end of the clamping rod. The second spring is sleeved on the outside of the clamping rod, one end of the second spring is fixedly connected to the bracket, and the other end of the second spring is fixedly connected to the pinching handle. A clamping block is fixed on the surface of the feeding hopper, and a through clamping hole is provided on the clamping block. The end of the clamping rod away from the pinching handle can be matched and inserted into the clamping hole to achieve a clamping effect.

[0010] Furthermore, a plurality of first springs are distributed between the four inner walls of the feed port and the four outer walls of the hopper. One end of each first spring is fixed to the inner wall of the feed port and the other end is fixed to the outer wall of the hopper. A vibration motor is also fixedly installed on the outside of the hopper.

[0011] Furthermore, a drying mechanism is provided on the side of the feed port and below the feeding hopper, and the drying mechanism is used to heat external air and blow it into the feed port to dry the rice falling into the feed port.

[0012] Furthermore, the drying mechanism includes an air inlet sleeve, a heating motor and a heating device. The air inlet sleeve is installed on one side of the feed port and extends into the feed port. The heating motor is installed in the air inlet sleeve. The heating device is installed in the air inlet sleeve and is located on the downstream side of the heating motor.

[0013] Furthermore, the heating device adopts an electric heating network, there are three heating devices, and the three heating devices are distributed in the air inlet sleeve at intervals.

[0014] Furthermore, a filter is installed in the air inlet sleeve on the upstream side of the heating motor, and a protective net is installed in the air inlet sleeve on the downstream side of the heating device.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0016] 1. The utility model forms a fence by the U-shaped plate above the filter plate and the blocking plate arranged on the side thereof, thereby forming a groove structure above the filter plate. The filtered large particles of impurities can be temporarily stored in the groove. When the filter plate is removed to clean the large particles of impurities, the fence can provide protection for the large particles of impurities from the four sides of the filter plate, preventing the impurities from rolling down from the side of the filter plate and falling into the color sorter body.

[0017] 2. In the utility model, since the slot is arranged obliquely, the filter plate inserted therein is also arranged obliquely. Under the action of gravity, the large particles of impurities to be filtered out will roll down along the filter plate, so that the impurities can accumulate on one side of the filter plate, leaving other parts of the filter plate free, and will not affect the normal filtering of rice.

[0028] See also Figure 1-Figure 6 The utility model provides a color sorter for rice processing, comprising a color sorter body 1, a feed port 2 arranged at the top of the color sorter body 1, and a hopper 3 arranged above the feed port 2, the bottom end of the hopper 3 is inserted into the feed port 2, one side of the hopper 3 is provided with an opening 31, and two inner side walls of the hopper 3 are provided with obliquely extending slots 32, and the two slots 32 are both connected with the opening 31, and a filter plate 4 is slidably inserted in the two slots 32, and a sealing plate 42 is fixed on one side of the filter plate 4, and the sealing plate 42 can fit into the opening 31 and seal the opening 31, a U-shaped plate 41 is fixed on the top of the filter plate 4, and the U-shaped plate 41 and the sealing plate 42 form a fence above the filter plate 4, and a clamping mechanism 5 is provided on the side of the hopper 3, and the clamping mechanism 5 is used to clamp the hopper 3 and limit it in the opening 31.

[0029] When the color sorter is used to screen rice, the grinding is put in from the top of the hopper 3, and the rice falls into the feed port 2 in the hopper 3, and finally falls into the color sorter body 1 for screening. The module components for color sorting rice in the color sorter body 1 adopt the existing technology, and the specific structure, installation and connection method and working principle are no longer repeated in this application. When the rice falls in the hopper 3, the filter plate 4 can be used to filter out the large particles of impurities such as sand and stone mixed in the rice, so as to achieve pre-filtration before the rice is color sorted. The color sorter is controlled to stop, and the clamping of the blocking plate 42 is canceled by operating the clamping mechanism 5, so that the filter plate 4, the U-shaped plate 41 and the blocking plate 42 can be removed from the hopper 3 as a whole, so as to facilitate the regular cleaning of the large particles of impurities temporarily stored above the filter plate 4.

[0030] The U-shaped plate 41 above the filter plate 4 and the blocking plate 42 arranged on the side thereof together form a fence, thereby forming a groove-like structure above the filter plate 4, and the filtered large particles of impurities can be temporarily stored in the groove. When the filter plate 4 is removed to clean the large particles of impurities, the fence can provide protection for the large particles of impurities from the four sides of the filter plate 4, preventing the impurities from rolling down from the side of the filter plate 4 and falling into the color sorter body 1. In addition, since the slot 32 is arranged obliquely, the filter plate 4 inserted therein is also arranged obliquely, and the filtered large particles of impurities will roll down along the filter plate 4 under the action of gravity, so that the impurities can accumulate on one side of the filter plate 4, leaving other parts of the filter plate 4, and will not affect the normal filtering of rice.

[0031] Specifically, when the filter plate 4 is fully inserted into the slot 32 , the three outer walls of the U-shaped plate 41 are respectively slidably fitted tightly with the three inner walls of the hopper 3 to prevent rice from falling into the cavity formed between the outer wall of the U-shaped plate 41 and the inner wall of the hopper 3 .

[0032] Specifically, the clamping mechanism 5 includes a bracket 51, a clamping rod 52, a pinching handle 53 and a second spring 54. The bracket 51 is fixed to the side of the feeding hopper 3. The bracket 51 is provided with a through sliding hole 511. The clamping rod 52 is inserted and slidably inserted into the sliding hole 511. One end of the clamping rod 52 is fixed with the pinching handle 53. The second spring 54 is sleeved on the outside of the clamping rod 52. One end of the second spring 54 is fixedly connected to the bracket 51, and the other end of the second spring 54 is fixedly connected to the pinching handle 53. A clamping block 55 is fixed on the surface of the feeding hopper 3. The clamping block 55 is provided with a through clamping hole 56. The end of the clamping rod 52 away from the pinching handle 53 can be matched and inserted into the clamping hole 56. The clamping effect is realized by pinching the pinching handle 53 and pulling the clamping rod 52 to retract its end. At this time, the second spring 54 is compressed and stored, and the filter plate 4 is inserted into the feeding hopper 3. After ensuring that the blocking plate 42 is completely fitted into the opening 31, the pinching handle 53 is then loosened, and the clamping rod 52 is pushed to slide back to its original position under the elastic force of the second spring 54. The end of the clamping rod 52 is aligned and inserted into the clamping hole 56 to achieve the clamping of the blocking plate 42. When disassembling, it is only necessary to pinch the pinching handle 53 again to pull the clamping rod 52 to drive the end of the clamping rod 52 to come out of the clamping hole 56, so that the filter plate 4, the U-shaped plate 41 and the blocking plate 42 can be conveniently removed from the feeding hopper 3 as a whole.

[0033] Specifically, a plurality of first springs 301 are evenly distributed between the four inner walls of the feed port 2 and the four outer walls of the hopper 3, one end of each first spring 301 is fixed to the inner wall of the feed port 2, and the other end is fixed to the outer wall of the hopper 3. A vibration motor 302 is also fixedly installed on the outer side of the hopper 3. The feed port 2 and the hopper 3 are connected by using the first springs 301, so that the feed port 2 and the hopper 3 have the ability to move with each other. The vibration generated by the vibration motor 302 can drive the hopper 3 to vibrate, so that the grinding vibration falling on the filter plate 4 can be evenly distributed, avoiding blockage caused by excessive accumulation of rice, and improving the pre-filtration effect of rice.

[0034] Specifically, a drying mechanism 6 is provided at the side of the feed port 2 and below the hopper 3 . The drying mechanism 6 is used to heat external air and blow it into the feed port 2 to dry the rice falling into the feed port 2 .

[0035] Specifically, the drying mechanism 6 includes an air inlet sleeve 61, a heating motor 62 and a heating device 63. The air inlet sleeve 61 is installed on one side of the feed port 2 and extends into the feed port 2. The heating motor 62 is installed in the air inlet sleeve 61. The heating device 63 is installed in the air inlet sleeve 61 and is located on the downstream side of the heating motor 62. The external air is sucked into the air inlet sleeve 61 and blown into the feed port 2 by the operation of the heating motor 62. The passing air can be heated by the operation of the heating device 63 to form a hot air flow, which can dry the rice falling into the feed port 2 to prevent the rice from clumping due to moisture and affecting the color sorting effect.

[0036] Specifically, the heating device 63 adopts an electric heating network. There are three heating devices 63, and the three heating devices 63 are spaced apart in the air inlet sleeve 61. Electric heating is used as the heating device 63, and it can heat up when powered on. The heat generation method is direct and rapid. In addition, the three heating devices 63 are spaced apart, which can achieve multiple heating of the air, improve the uniformity of air heating, and thus improve the drying effect of the rice.

[0037] Specifically, a filter 64 is installed in the air inlet sleeve 61 on the upstream side of the heating motor 62 to filter dust and impurities in the air to prevent contamination of the rice. A protective net 65 is installed in the air inlet sleeve 61 on the downstream side of the heating device 63 to prevent rice from splashing into the air inlet sleeve 61.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
