Description

Technical Field

[0001] The utility model relates to the field of a drum screen of a cyperus rotundus cleaning machine, in particular to a drum screen device of the cyperus rotundus cleaning machine. Background Art

[0002] The cyperus terrestris cleaning machine is a device specially used to clean impurities in cyperus terrestris. Since cyperus terrestris will be mixed with various impurities during the growth and harvesting process, such as broken and crushed stems, husks, dust, stones, etc., these impurities will affect the quality and utilization value of cyperus terrestris, so it is necessary to use a cyperus terrestris cleaning machine to clean them.

[0003] In practical applications, drum screens face an important problem when screening cyperus rotundus: weed contamination. Since cyperus rotundus and some weeds are similar in size, shape and density, it is difficult for drum screens to completely distinguish them. This leads to reduced screening efficiency and increased impurity content in cyperus rotundus, affecting its quality and market value. The presence of weeds makes the material composition inside the drum screen more complex, increasing the difficulty of screening. To ensure the purity of cyperus rotundus, the screen needs to be checked and adjusted more frequently, which also increases the difficulty of operation and maintenance. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 5 As shown, a drum screen device of a cyperus rotundus cleaning machine comprises: a bracket 1 for supporting the entire drum screen device; a driving device 2 and a transmission device 3 are mounted on the bracket 1 for driving the operation of the drum screen device; a feed barrel 4 and a discharge barrel 5 are mounted on the bracket 1 through the transmission device 3 for feeding and discharging cyperus rotundus; a filter screen 6 is arranged between the feed barrel 4 and the discharge barrel 5 for screening cyperus rotundus; a feed port 7 is arranged at the opening of the feed barrel 4 for adding cyperus rotundus to be screened; a fixed door 8 is mounted on the top of the discharge barrel 5, and is connected to a flip door 10 through a hinge device 9 for controlling the switch of the discharge barrel 5; the flip door 10 is used to discharge the screened cyperus rotundus;

[0024] The fixing sleeve 11 is arranged at the outer end of the flip door 10 and connected to the rotating head 12; the rotating head 12 has a plurality of inclined rods 14 at its inner end for winding weeds; barbs 15 are arranged on the inclined rods 14 for enhancing the winding effect on weeds.

[0025] In addition, the fixed door 8 is welded to the discharge barrel 5, and the inner wall of the discharge barrel 5 is provided with a "C"-shaped ring, and the inner wall thereof is provided with a sealing ring to ensure that the flip door 10, the fixed door 8 and the sealing ring are tightly fitted to prevent leakage of the cyperus rotundus. The fixed door 8, the flip door 10 and the hinge device 9 are fixed by bolts and gaskets to ensure the stability of the structure. The cross section of the rotating head 12 is designed in a "T" shape, and its side wall sleeve is provided with a sealing ring, and is sealed and connected with the fixed sleeve 11 to prevent the entry of debris. The outer wall of the rotating head 12 is provided with a handle for easy operation. A plurality of inclined rods 14 are fixed to the rotating head 12 by threads, and the inclination angle thereof is consistent with the inclination angle of the filter screen 6, ensuring that the cyperus rotundus can slide down and be discharged smoothly. A plurality of barbs 15 are equidistantly distributed on the inclined rod 14, and are designed as a whole with the inclined rod 14, which enhances the winding effect on weeds.

[0026] Filtration process: the cyperus rotundus to be screened is added into the feed barrel 4 through the feed port 7; the driving device 2 is started, and the drum screen device is driven to operate through the transmission device 3; the cyperus rotundus enters the filter screen 6 from the feed barrel 4, and the design of the screen can screen out the cyperus rotundus that meets the size requirements, and filter out the weeds and other impurities therein; the screened cyperus rotundus continues to slide along the filter screen 6, and is finally discharged from the discharge barrel 5;

[0027] When the cyperus rotundus slips on the filter screen 6, the weeds and other impurities therein will be intercepted by the screen; at this time, the rotating head 12 is started to start rotating. The multiple inclined rods 14 on the rotating head 12 rotate accordingly; the inclination angle of the inclined rod 14 is consistent with the inclination angle of the filter screen 6, so that the weeds are more easily contacted and entangled by the inclined rod 14 during the sliding process; the barbs 15 are arranged on the inclined rod 14, and their sharp shape enhances the entanglement effect on the weeds, making it more difficult for the weeds to fall off the inclined rod 14; as the rotating head 12 continues to rotate, the weeds entangled by the inclined rod 14 and the barbs 15 are gradually collected and discharged, thereby achieving the cleaning and screening of the cyperus rotundus; in the whole process, the filter screen 6 plays a major screening role, while the inclined rod 14 and the barbs 15 enhance the screening effect, making the cleaning and screening process of the cyperus rotundus more efficient and accurate. At the same time, the close fit and stable structure between the various components also ensure the stable operation and long-term use of the entire device.
