Description

Technical Field

[0001] The utility model relates to the technical field of rice, in particular to a rice fast crushing device for rice processing. Background Art

[0002] Rice is one of the staple foods of people. With the improvement of people's living standards, rice is not only used as a staple food, but also processed into a variety of other products. In the deep processing of rice, it is often necessary to crush the rice and make it into powder before subsequent processing and utilization.

[0003] The Chinese patent document with application number 202122209761.6 in the related art proposes a fast and efficient rice crushing device. Before starting work, it first moves the device to the required place through the universal wheel, and then starts the driving member. Under the action of the driving member, the driving gear is driven to rotate. Since the driving gear is meshed with the first driven gear and the second driven gear, the rotation of the first driven gear drives the rotating shaft to rotate between the driving box and the fixed seat and inside the sleeve shaft, thereby driving the crushing block to rotate inside the crushing bin. The rotation of the second driven gear drives the sleeve shaft to rotate inside the support plate and the driving box, thereby driving the fixed seat to rotate. The fixed seat drives the crushing bin to rotate through the connecting plate, thereby driving the rotating plate to slide inside the fixed plate. The ball rolls along the inner side of the fixed plate while rotating inside the rotating plate, and the crushing block rotates in the opposite direction to the crushing bin. The rice to be processed is added to the inside of the crushing bin, and the rice is crushed under the rotation of the crushing block and the crushing bin.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the device crushes the rice through the action of the crushing block and the crushing bin, which increases the resistance to crushing when the whole rice is directly crushed, thereby reducing the work efficiency; since the crushing block and the crushing bin act directly on the rice, the rice is not crushed very uniformly. If uniform rice is required, separate screening is required, which is not only complicated to operate but also low in work efficiency. In view of this, a rice rapid crushing device for rice processing is proposed to solve the above problems. Utility Model Content

[0019] See also Figure 1-2 In this embodiment, a rice rapid crushing device for rice processing includes a box body 1, a feed port 7 is opened at the upper end of the box body 1, a discharge port 4 is opened at the lower end of the box body 1, two rotatable crushing rollers 3 are arranged in the box body 1, and the crushing rollers 3 are driven to rotate by an external driving member to perform preliminary crushing of rice, a cleaning mechanism 5 is arranged in the box body 1, a screening component 6 is arranged in the box body 1, and a crushing device 2 is arranged in the box body 1.

[0020] The cleaning mechanism 5 includes an air compressor 501 and a support 506 for an air tank 503. The air compressor 501 is fixedly installed on the box body 1. The air outlet pipe 508 of the air compressor 501 has a first air supply pipe 502. One end of the first air supply pipe 502 is connected to the air tank 503. The air tank 503 is fixedly installed on the box body 1. A pressure gauge 504 is fixed on the air tank 503. Two supports 506 are fixed in the box body 1. Multiple diversion tanks 509 are fixed in the supports 506. A second air supply pipe 505 is connected between one end of the diversion tank 509 and the air tank 503. An air outlet pipe 508 is fixed to the other end of the diversion pipe, and an electromagnetic valve 507 is fixed on the air outlet pipe 508.

[0021] The device starts the air compressor 501, which transports gas to the first air supply pipe 502 from the air tank 503. The gas in the air tank 503 then flows into the second air supply pipe 505 and then into the diversion tank 509. At this time, the solenoid valve 507 is closed, and the air is continuously supplied through the air compressor 501. By observing the pressure gauge 504, when the air pressure reaches the set pressure, the solenoid valve 507 is opened to allow the gas to be ejected to blow off and clean the outer side of the crushing roller 3.

[0022] The two brackets 506 are respectively located on both sides of the two crushing rollers 3 , and the air outlet pipe 508 is located on the crushing roller 3 , so as to facilitate cleaning of the outer sides of the two crushing rollers 3 .

[0023] At the same time, the crushing device 6 includes a rotating motor, a crushing block, and a side plate. A rotating motor is arranged in the middle of the inner cavity of the box body 1, and a crushing block is fixed to the output end of the rotating motor. A side plate is arranged on the inner side of the box body 1. An air crushing block for grinding rice is arranged between the crushing block and the side plate and is located under the crushing roller 3.

[0024] See also Figure 1 The screening component 6 in this embodiment includes a screen 601, a discharge port 604 and a cam 603. The screen 601 is hinged on the right side of the inner cavity of the box body 1. A rotatable cam 603 is horizontally arranged in the box body 1. One end of the cam 603 is fixed to an external motor, and the outer side of the cam 603 is slidably connected to the lower end of the screen 601. A discharge port 604 is opened on one side of the box body 1.

[0025] The device starts an external motor, which drives the cam 603 to rotate, and then drives the screen 601 to move up and down during the rotation of the cam 603 to screen the rice.

[0026] Among them, the screen 601 is located in the discharge port 604, and a wear-resistant plate 605 is fixed to the lower end of the screen 601 to facilitate the discharge of unqualified rice from the discharge port 604. The outer side of the wear-resistant plate 605 is slidably connected to the lower end of the screen 601 to increase the service life of the screen 601.

[0027] At the same time, a spring 602 is fixed to the right end of the screen 601 , and one end of the spring 602 is fixed to the right side of the inner cavity of the box body 1 . Through the setting of the spring 602 , the screen 601 is always in contact with the cam 603 .

[0028] The working principle of the above embodiment is:

[0029] When the crushing roller 3 needs to be cleaned, start the air compressor 501 to transport the gas to the first air supply pipe 502 from the air tank 503, and then the gas in the air tank 503 flows into the second air supply pipe 505, and then enters the diversion tank 509. At this time, the solenoid valve 507 is closed, and then the air compressor 501 continues to supply air. Then, by observing the pressure gauge 504, when the air pressure reaches the set pressure, the solenoid valve 507 is opened to allow the gas to spray out and blow off and clean the outside of the crushing roller 3.

[0030] When the rice falls onto the screen 601, the external motor is started, which drives the cam 603 to rotate, and the cam 603 drives the screen 601 to move up and down during the rotation to screen the rice. Unqualified rice is discharged from the discharge port 604, and qualified rice falls from the holes in the screen 601 and is discharged from the discharge port 4 for collection.
