Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rice processing, in particular to a rice rapid crushing device for rice processing. Background Art
[0002] Rice is a staple food in people's daily life, and its processing process plays a vital role in meeting people's dietary needs. In the rice processing process, crushing is one of the key steps, which is directly related to the quality and processing efficiency of rice products. However, the existing rice processing crushing equipment has some obvious shortcomings in crushing speed.
[0003] First of all, the traditional crushing equipment only uses two rollers for extrusion and crushing. In order to make the crushing force stronger and allow the rollers to obtain a larger torque, the motor needs to be decelerated by a reducer with a larger speed ratio and then drive the rollers to rotate. This results in a slower speed of the rollers, making the rice crushing efficiency low. Utility Model Content
[0004] In order to solve the deficiencies of the prior art, the utility model provides a rice rapid crushing device for rice processing, comprising a shell, a feeding hopper is opened on the top of the shell, two rolling rollers are rotatably connected in the shell, a primary crushing area is formed between the two rolling rollers, two grinding discs are rotatably connected in the shell, a secondary crushing area which is wide at the top and narrow at the bottom is formed between the two grinding discs, the secondary crushing area is located below the primary crushing area and in the same plane, a first drive motor drives one of the rolling rollers to rotate, and a second drive motor drives one of the grinding discs to rotate.
[0005] Preferably, two upper guide plates are fixedly installed in the outer shell, and the two upper guide plates are respectively located above the two grinding discs, and the two upper guide plates are in an inverted "eight" shape.
[0006] Preferably, side guide plates are fixedly mounted on both ends of the upper guide plates, respectively, and the side guide plates close one side of the same end of the two upper guide plates.
[0007] Preferably, two arc-shaped baffles are fixedly installed in the shell, and the two arc-shaped baffles respectively wrap the openings on two opposite sides of the secondary crushing area, and the upper guide plate and the side guide plate are fixedly connected to the top of the arc-shaped baffles.
[0008] Preferably, a mounting frame is fixedly installed in the outer shell, a shaft rod is fixedly installed on the mounting frame, and the grinding disc not connected to the second driving motor is rotatably connected to the shaft rod.
[0009] The utility model has the following beneficial effects:
[0010] After the rice is initially crushed in the primary crushing area between the two rolling rollers, it becomes broken particles, and then falls into the secondary crushing area between the two grinding discs by gravity for further grinding, so that the broken particles are further crushed into powder. Since the two rolling rollers are only responsible for the initial crushing of the rice, the distance between the two rolling rollers can be larger than that of the existing grinder, so that the torque required by the rolling rollers is also reduced accordingly, so that the rotation speed of the rolling rollers can be further increased accordingly, so that the crushing speed is accelerated and the efficiency is improved.

[0015] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0016] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.
[0017] In a specific embodiment, Figure 1-2 As shown, a rice rapid crushing device for rice processing comprises a shell 1, a feeding hopper 2 is provided on the top of the shell 1, two rolling rollers 3 are rotatably connected in the shell 1, a primary crushing area 4 is formed between the two rolling rollers 3, two grinding discs 6 are rotatably connected in the shell 1, a secondary crushing area 7 which is wide at the top and narrow at the bottom is formed between the two grinding discs 6, the secondary crushing area 7 is located below the primary crushing area 4 and in the same plane, a first drive motor 5 drives one of the rolling rollers 3 to rotate, and a second drive motor 11 drives one of the grinding discs 6 to rotate.
[0018] like Figure 1As shown, in this embodiment, two upper guide plates 8 are fixedly installed in the outer shell 1, and the two upper guide plates 8 are respectively located above the two grinding discs 6. The two upper guide plates 8 are in an inverted "eight" shape to catch the fragments falling from the primary crushing area 4 to prevent the fragments from splashing. The bottom of the upper guide plate 8 is in an inward concave arc shape that fits with the top of the grinding disc 6.
[0019] like Figure 2 As shown, further, side guide plates 9 are fixedly installed at both ends of the upper guide plate 8, and the side guide plates 9 close one side of the same end of the two upper guide plates 8 to prevent broken particles from leaking out from the end surface of the upper guide plate 8.
[0020] In this embodiment, two arc-shaped baffles 10 are fixedly installed in the housing 1, and the two arc-shaped baffles 10 respectively wrap the openings on the two opposite sides of the secondary crushing area 7, and the upper guide plate 8 and the side guide plate 9 are fixedly connected to the top of the arc-shaped baffles 10. In order to prevent the broken pieces from escaping from the secondary crushing area 7 during the grinding process, the top of the secondary crushing area 7 is opened to receive the broken pieces, and the bottom is opened to discharge the ground rice flour.
[0021] According to actual needs, the above-mentioned rice rapid crushing equipment for rice processing can be further optimized and / or improved:
[0022] The distance between the secondary crushing zone 7 and the bottom horizontal line of the arc-shaped baffle 10 is the maximum diameter of the crushed rice particles required for crushing.
[0023] The length of the upper guide plate 8 matches the length of the rolling roller 3, and the distance between the upper guide plate 8 and the rolling roller 3 is smaller than the distance between the two rolling rollers 3. The broken particles cannot fly out from the gap between the upper guide plate 8 and the rolling roller 3.
[0024] A mounting frame 12 is fixedly installed in the outer shell 1, and a shaft 13 is fixedly installed on the mounting frame 12. The grinding disc 6 not connected to the second drive motor 11 is rotatably connected to the shaft 13, so that the two grinding discs 6 can rotate synchronously to rotate the broken particles on the top to the bottom to crush them into smaller particles.
[0025] In summary: after the rice is initially crushed in the primary crushing area 4 between the two rolling rollers 3, it becomes broken particles, and then falls into the secondary crushing area 7 between the two grinding discs 6 by gravity for further grinding, so that the broken particles are further crushed into powder. Since the two rolling rollers 3 are only responsible for the initial crushing of the rice, the distance between the two rolling rollers 3 can be larger than that of the existing grinder, so that the torque required by the rolling rollers 3 is also reduced accordingly, so that the rotation speed of the rolling rollers 3 can be further increased accordingly, so that the crushing speed is accelerated and the efficiency is improved.
