Description

Technical Field

[0001] This utility model relates to the field of rhubarb processing technology, specifically to a grading vibrating screen device for rhubarb processing. Background Technology

[0002] Traditional Chinese medicine (TCM) uses unique medicinal herbs for the prevention and treatment of diseases, and is an important marker distinguishing TCM from other medical systems. Rhubarb is one such herb, a collective term for several perennial plants belonging to the genus *Rheum* in the Polygonaceae family. In Chinese literature, "rhubarb" often refers to *Rheum palmatum*. While primarily used medicinally in China, in Europe and the Middle East, "rhubarb" often refers to several other edible species of the *Rheum* genus. These species have red stems, a fragrant aroma, a bitter and slightly astringent taste, and a sticky, gritty texture when chewed. They are harvested in late autumn when the stems and leaves wither, or before sprouting in the following spring. The fine roots are removed, the outer skin is scraped off, and the rhubarb is cut into segments or sections, strung together, and dried, or dried directly. Rhubarb has the effects of purging stagnation, clearing damp heat, purging fire, cooling blood, removing blood stasis, and detoxifying. However, current rhubarb processing methods are inconvenient for multi-stage screening, and the screening efficiency is poor, affecting the quality of the processed rhubarb. Therefore, a grading and vibrating sieve device for rhubarb processing is proposed to address these problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a grading vibrating screen device for rhubarb processing, including a box body, on which a screening mechanism and a vibration mechanism are respectively arranged;

[0005] The screening mechanism includes: two discharge ports and two screen plates. The two discharge ports are respectively opened on the right side of the box. The two screen plates are slidably connected to the inner wall of the box. The mesh diameter of the upper screen plate is twice that of the lower screen plate. The right sides of both screen plates are inclined downward and extend out of the two discharge ports respectively. Springs are fixedly connected to the four corners of the bottom of each screen plate. The bottom ends of the two springs on the left are fixedly connected to the fixing blocks, and the fixing blocks are fixedly connected to the inner wall of the box. The bottom ends of the two springs on the right are fixedly connected to the inner wall of the discharge port.

[0006] The vibration mechanism includes: two fixed rods and a rotating shaft. The two fixed rods are respectively fixedly connected to the inner walls of the front and rear sides of the housing. A mounting bracket is fixedly connected between the two fixed rods. A rack is slidably connected to the inner cavity of the mounting bracket. The rack is arranged in an "O" shape. Top rods are fixedly connected to the upper and lower sides of the rack. A top block is fixedly connected to the end of each top rod away from the rack. The rotating shaft is rotatably connected to the inner wall of the left side of the housing through a bearing. The right end of the rotating shaft passes through the mounting bracket and extends to the right. A sector gear is fixedly connected to the extended end of the rotating shaft, and the sector gear meshes with the rack.

[0007] Preferably, the mounting bracket is U-shaped, and the inner cavity of the mounting bracket has a sliding groove. The outer wall of the rack is slidably connected to the sliding groove, and the rack slides along the inner wall of the sliding groove to improve the stability of movement.

[0008] Preferably, a motor is connected to the left side of the housing, and the left end of the rotating shaft passes through the housing and is fixedly connected to the output end of the motor through a coupling. The rotating shaft can be driven to rotate by starting the motor.

[0009] Preferably, a feed hopper is fixedly connected to the top of the box and is located near the left side of the box, and a box door is hinged to the lower front of the box via a hinge.

[0010] Preferably, the housing is provided with a dust removal mechanism, which includes: a dust collection box, the dust collection box being fixedly connected to the back of the housing, an air suction hood being fixedly connected to the front of the dust collection box, an installation hole being provided on the back of the housing, the opening end of the air suction hood being located in the installation hole, an exhaust fan being connected to the back of the dust collection box, and a filter screen being fixedly connected to the inner wall of the dust collection box and close to the back of the dust collection box.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This grading vibrating screen device for rhubarb processing facilitates the grading and screening of rhubarb through two screen plates with different mesh diameters, improving screening quality. The rotating shaft drives the sector gear to rotate, which in turn drives the rack to move up and down, thereby moving the rack, the top rod, and the top block. This causes the two top blocks to push the two screen plates in sequence, while the screen plates vibrate up and down under the elastic force of the springs. This prevents the rhubarb from clogging the mesh of the screen plates, improves screening efficiency, and is highly practical.

[0014] 2. This grading and vibrating sieve device for rhubarb processing generates negative pressure in the dust collection box and suction hood by starting the exhaust fan, thereby drawing out the dust from the box. At the same time, the dust is retained in the dust collection box by the filter screen plate, and clean air is discharged through the exhaust fan, preventing dust from overflowing from the box and polluting the environment during screening. The sealing cover is rotated to separate it from the ash discharge pipe, thereby opening the ash discharge pipe and facilitating the discharge of dust from the dust collection box, thus improving the ease of use.
