Description

Technical Field

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

[0002] In the prior art, a rice color sorter with application number "201810202484.6" includes a machine bin, a feed port, a slide plate and an induction zone bin, a feed port is installed above the machine bin, and a dividing plate is evenly installed inside the feed port, a vibration motor is installed on one side of the feed port, a telescopic rod is hinged below the feed port away from the vibration motor, a discharge plate is hinged to the feed port below the telescopic rod, and the output end of the telescopic rod is hinged to the discharge plate, the rice color sorter is equipped with a feed port, a vibration motor and a dividing plate, and a hinged discharge plate is installed inside the feed port, and the angle of the discharge plate can be adjusted according to the type of rice, so that the rice falls more evenly and will not pile up together, so that the color sorting effect is better, the slide plate is installed in a hinged manner, and the angle of the slide plate can be adjusted to control the falling speed of the rice, and the surface of the slide plate is grooved, which can adapt to the shape of the rice to let it fall, so that the color sorting is better.

[0003] However, there are still obvious defects in the process of use: 1. The above device uses a one-time color sorting method to screen good rice and waste rice, and the rice is carried out in large quantities. More high-quality rice is directly discarded, causing waste of grain crops, and the error is large; 2. The above device can only screen according to the color of the rice, so as to select good rice and waste rice and some other impurities, but cannot color sort the size of the rice grains. In the actual processing process, the rice grains need to be sorted by a special rice grain size screening machine before and after the color sorting, which not only increases energy consumption, but also seriously affects the work efficiency; 3. At present, most color sorters on the market can basically achieve a color sorting accuracy of 99.99% when the impurity content is 2%. In addition to the fact that the impurity content will affect the color sorting effect of the color sorter, the output per unit time is also one of the key factors. The output is inversely proportional to the accuracy of the color sorter, that is, the greater the output per unit time, the worse the color sorting effect. Therefore, in actual use, the operator is often required to manually adjust the feed rate according to the raw material waste rate to achieve the best color sorting effect, but relying on manual judgment is not only inaccurate, but also more cumbersome to operate.

If the broken rice rate in the batch of rice materials is high, the built-in cylinder 13 can be arranged upward so that the good product box 12 below can reserve a larger space for storing the broken rice, which is flexible to use. A groove ring 151 is provided at the bottom of the built-in cylinder 13, and a screening mesh plate 152 is provided in the groove ring 151. The screening mesh plate 152 is used to screen whole rice and broken rice. A compression spring 153 is connected between the screening mesh plate 152 and the groove ring 151. When rice grains fall, the screening mesh plate 152 will be impacted, so that the compression spring 153 is compressed or stretched, and the screening mesh plate 152 vibrates, thereby preventing the screening mesh plate 152 from being blocked by the broken rice.

[0051] A base frame 161 is provided at the bottom of the waste box 16, and a vibration spring 162 is connected between the waste box 16 and the base frame 161.

The electrical control box 2 is electrically connected to the telescopic cylinder 331, the weighing sensor 10, the anti-accumulation vibrator 163 and the infrared ranging sensor assembly 165, respectively, and these electrical equipment can be controlled.

[0053] As a preference, an elastic layer 154 is connected to the outlet of the sieve mesh plate 152 and the groove ring 151. The elastic layer 154 can relatively seal the groove ring 151 to prevent rice grains from being stuck inside the groove ring 151 and affecting the normal use of the device.

[0054] As a preferred embodiment, a rice blocking plate 166 is fixedly provided on the fixed plate 164 , and the rice blocking plate 166 is mainly provided to prevent the falling waste rice from damaging the infrared ranging sensor assembly 165 .

[0055] Working principle: At the beginning of color sorting, the rice material enters from the feeding chamber 1 322 of the feeding hopper 32, passes through the chute 1 36, and reaches the sorting device 4. After sorting, the good rice in the rice material flows out from the A port 54, and the rest all flow to the secondary elevator from the B port 55 for re-selection. The re-selected rice enters the feeding chamber 2 323 and flows out from the chute 2 37. After re-selection, the waste rice flows out from the D port 57, and the rest all flows out from the C port 56 and returns to the primary color sorting again, and this cycle is repeated until the color sorting is completed.

[0056] The good rice obtained after color sorting falls into the good box 12 of the collecting device 7, and the bad rice falls into the bad box 16. The good rice falling into the good box 12 will fall on the screening mesh plate 152, so that the screening mesh plate 152 is hit and drives the compression spring 153 to shake, which can not only improve the screening effect, but also prevent the screening mesh plate 152 from being blocked by rice grains. After being screened by the screening mesh plate 152, the broken rice falls to the bottom of the good box 12, and the whole rice grains in the good rice remain on the screening mesh plate 152, which is convenient for In addition, if the broken rice rate in a batch is high, the circular plate 14 can be rotated around the built-in cylinder 13 after removing the screw 143, so that the circular plate 14 is located at the lower part of the built-in cylinder 13, and then the screw 143 is screwed into the positioning screw hole 142 and the threaded blind groove 121, so that the built-in cylinder 13 is fixed on the good product box 12 through the circular plate 14, so that the space between the bottom of the built-in cylinder 13 and the bottom plate of the good product box 12 is increased, which is convenient for storing more broken rice. Vice versa.

[0057] The waste rice will fall into the waste box 16. Under the action of the anti-accumulation vibrator 163, the waste rice in the waste box 16 is evenly distributed without aggregation and accumulation. When the weighing sensor 10 detects that the total amount of good rice and waste rice on the load-bearing plate 11 reaches a predetermined value, the infrared ranging sensor assembly 165 is started by the automatic control device in the electric control box 2 to measure the height of the waste rice in the waste box 16. If the waste rice is high, the waste rate is high. The automatic control device in the electric control box 2 controls the telescopic cylinder 331 to start. The telescopic cylinder 331 drives the feed adjustment plate 33 to change its inclination angle, so that the feed flow rate is reduced, thereby effectively improving the color sorting accuracy. Vice versa, when the good rate is high, the material flow rate can be increased to quickly complete the color sorting, which is more intelligent while ensuring the color sorting effect.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
