Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a rice husk crusher. Background Technology

[0002] Rice husks are the largest by-product in rice processing. With extensive research on the comprehensive utilization of rice husks, they can be used to produce various chemical raw materials, livestock and poultry feed, edible fungi cultivation materials, and building materials. Among these, crushing is one of the basic processing techniques for rice husks, which has made a great contribution to their development and use.

[0003] A Chinese patent, CN222678250U, discloses a rice husk crushing and processing device. By using a rotating shaft and rotating tube, the first and second crushing blades can rotate in opposite directions, allowing for more thorough crushing of the rice husks and improving crushing quality. Simultaneously, a conveying mechanism can transport the crushed rice husks back to the crushing tank for secondary crushing, further improving the crushing quality and providing convenience. However, when secondary crushing rice husks that do not meet size requirements, the device cannot quickly screen the husks to separate qualified from unqualified husks, causing some unqualified husks to flow into the qualified husks, reducing the quality of rice husk crushing. Therefore, a rice husk crusher is proposed to solve the above problems. Utility Model Content

[0020] like Figure 1-3 As shown, the present invention proposes a rice husk crusher, which includes a screening frame 1, a crushing tank 2, and a screw conveyor 3. The crushing tank 2 is connected to the top of the screening frame 1, and the screw conveyor 3 is located on the right side of the crushing tank 2 and connected to its discharge end. It also includes an inlet protective frame 4, a partition 5, and a screen plate 6. The protective frame 4 is connected to the inlet end of the screw conveyor 3. The partition 5 is rotatably mounted on the top wall of the screening frame 1 and blocks the bottom end of the crushing tank 2. The screen plate 6 is inclinedly mounted inside the screening frame 1 and extends to its right side and into the protective frame 4. The screening frame 1 is equipped with a shaking mechanism that drives the screen plate 6 to shake up and down continuously.

[0021] In this invention, the mixing tank 2 is equipped with a rotating shaft, a rotating tube, a first crushing blade, a second crushing blade, and an auger. The top is equipped with a first bevel gear, a second bevel gear, a housing, a third bevel gear, and a motor. Under the action of the rotating shaft and rotating tube, the first and second crushing blades can rotate in opposite directions, allowing for more thorough crushing of the rice husks and improving crushing quality. The drive motor, through the installation of a partition and a hydraulic cylinder, can push the partition to block the bottom of the crushing tank, improving the crushing effect. An inclined sieve plate is installed inside the screening frame, extending into the protective frame. After crushing the rice husks, a shaking mechanism continuously pushes the sieve plate up and down to screen the crushed rice husks. Rice husks that do not meet the size requirements are conveyed along the screw conveyor. A guide plate, a guide tube, a protective housing, and two L-shaped plates work together to prevent rice husks from flowing out when the sieve plate vibrates, thus preventing rice husk waste.

[0022] In an optional embodiment, the shaking mechanism includes a motor 71, a rotating rod 72, a cam 73, multiple limiting rods 74, and multiple first springs 75. The motor 71 is located on the right side of the screening frame 1. One end of the rotating rod 72 is coaxially and fixedly connected to the output shaft of the motor 71, and the other end is rotatably connected to the left side wall of the screening frame 1. The cam 73 is coaxially and fixedly sleeved on the rotating rod 72, and its outer side contacts the bottom end of the sieve plate 6. The multiple limiting rods 74 are all connected to the bottom end of the sieve plate 6 and extend to the bottom of the screening frame 1. The multiple first springs 75 are respectively sleeved on the multiple limiting rods 74 and connected between the screening frame 1 and the sieve plate 6.

[0023] It should be noted that during the shaking, the starter motor 71 drives the rotating rod 72 to rotate, which in turn drives the cam 73 to rotate. By using the limit rod 74 and the first spring 75 in combination, the screen plate 6 is made to shake up and down continuously.

[0024] In an optional embodiment, a hydraulic cylinder 51 is hinged to the right side wall of the screening box 1, and the top end of the telescopic rod of the hydraulic cylinder 51 is hinged to the bottom end of the partition 5.

[0025] It should be noted that by activating the hydraulic cylinder 51 to push the baffle 5, the bottom of the mixing tank 2 is sealed, which improves the crushing effect. After crushing is completed, the baffle 5 is opened to release the rice husks.

[0026] In an optional embodiment, a guide pipe 61 is connected to the right side of the sieve plate 6 and extends into the protective frame 4, and a guide plate 62 is connected to the top of the sieve plate 6.

[0027] In an optional embodiment, the left side of the protective frame 4 has a feed port that matches the size of the feed tube 61.
