Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a vibrating destoner for rice processing. Background Technology

[0002] Rice is a cereal crop, usually referring to the finished grain obtained after paddy rice has been hulled. It is one of the important food crops for humankind. Rice can be cooked alone or with other ingredients to make a variety of delicious dishes. Rice can also be processed into rice noodles, rice cakes, rice wine and other foods, which are of great significance for maintaining human health and improving the quality of life.

[0003] The working principle of the vibrating destoner for rice processing is mainly based on the difference in specific gravity, shape and friction characteristics between rice and impurities such as stones: the rice to be processed is fed into the machine through the feed inlet, and then it is initially separated into larger rice grains and smaller stone impurities through the screen. The rice and stone impurities are further separated on the vibrating screen by utilizing the weight difference between the rice and stone impurities.

[0004] Currently, some dust is generated during the vibration screening process of rice. However, existing vibratory destoners for rice processing usually do not have dust removal functions during screening, causing dust on the surface of the rice to be suspended in the nearby air due to vibration, which has an adverse effect on the surrounding air quality and working environment. Utility Model Content

[0010] A dust pump is fixedly installed on the top of the enclosure;

[0011] The vacuum pump's input end is connected to a vacuum hose;

[0012] The end of the suction hose furthest from the vacuum pump is connected to an air duct;

[0021] The beneficial effects of this utility model are:

[0022] 1. The rice to be screened is vibrated and screened on the second vibrating screening plate of the equipment. The dust on the surface of the rice to be screened will be suspended in the nearby air due to the vibration. Then, by starting the dust pump, the dust is transported through the dust suction pipe to the dust collection box for collection and centralized treatment, so as to avoid the dust generated during the rice stone removal process from having an adverse impact on the surrounding air quality and working environment.

[0023] 2. The filter screen installed in this device can block and intercept the lighter rice husks that are accompanied by dust during normal screening. When screening is not required, the filter screen is rotated by starting the speed-regulating motor, and the vacuum pump's reverse air intake cleans the empty rice husks attached to the surface of the filter screen.

[0034] Example 2

[0035] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a second support base 18 is fixedly connected to the bottom of the inner cavity of the box 2, a third support spring is fixedly connected to the top of the second support base 18, and the end of the third support spring away from the second support base 18 is fixedly connected to the bottom of the first vibrating screening plate 11. A feeding box 6 is fixedly connected to the outer surface of the box 2, and a feeding hopper 7 is connected to the outer surface of the feeding box 6. A servo motor for driving the rotating shaft 8 to rotate is fixedly installed on the top of the feeding box 6. The rotating shaft 8 is rotatably connected to the bottom of the inner cavity of the feeding box 6, and a spiral blade 9 is fixedly connected to the outer wall of the rotating shaft 8. A guide plate 14 is fixedly installed on the inner cavity wall of the box 2.

[0036] A dust collection box 5 is fixedly connected to the top of the box 2. A connecting pipe 10 is connected to the output end of the dust pump 4. The end of the connecting pipe 10 away from the dust pump 4 is connected to the outer surface of the dust collection box 5. A second mounting base 16 is fixedly connected to the inner wall of the box 2. A support spring 4 is fixedly connected to the top of the second mounting base 16. The end of the support spring 4 away from the second mounting base 16 is fixedly connected to the bottom of the second vibrating screening plate 15. A discharge hopper 17 is connected to the bottom of the inner cavity of the box 2. An installation groove is opened through the outer surface of the box 2. A dust collection box 19 is slidably connected to the inner wall of the installation groove.

[0037] The remaining structure is the same as that in Example 1.

[0038] During use, the rice to be screened is fed from the feed hopper 7 into the feeding box 6. The servo motor is started to drive the rotating shaft 8 to rotate, which in turn drives the spiral blades 9 to rotate. The rice to be screened falls onto the second vibrating screening plate 15 via the guide plate 14. The second vibration motor is started to drive the second vibrating screening plate 15 to vibrate and screen the rice, so that the dust on the surface of the rice to be screened will be suspended in the nearby air due to the vibration.

[0039] During use, the dust pump 4 is then started, and the dust is transported to the dust collection box 5 through the dust suction pipe 3 for collection and centralized processing. During normal screening, the filter screen 22 can block and intercept the lighter rice husks that are adsorbed along with the dust in the screened rice. When screening is not required, the speed-regulating motor is started to drive the filter screen 22 to rotate. With the reverse air intake of the dust pump 4, the empty rice husks attached to the surface of the filter screen 22 are cleaned. After dust removal, the rice falls onto the first vibrating screening plate 11 under the tilt angle and vibration force of the second vibrating screening plate 15.

[0040] During use, the first vibrating motor is started to drive the first vibrating screening plate 11 to screen the rice after dust removal. The screening mesh 12 on the first vibrating screening plate 11 intercepts the rice on its surface, while smaller stones pass through the screening mesh 12 and fall into the collection box 19 below for centralized processing. The screened rice falls into the discharge hopper 17 below under the tilt angle and vibration force of the first vibrating screening plate 11, and then flows out through the discharge hopper 17 for collection or packaging by the staff.
