Abstract
Description
Technical Field
[0001] This utility model relates to the field of soybean washing machine technology, specifically to a stirring mechanism for a soybean washing machine. Background Technology
[0002] A bean washing machine is a specialized piece of equipment used to clean grains (such as soybeans, peas, mung beans, etc.) and remove impurities. It is widely used in grain processing, bean product production, eight-treasure porridge processing, pet food processing and other fields.
[0003] The prior art discloses a stirring mechanism for a bean washing machine, with publication number CN220607255U. The mechanism includes a barrel, a motor mounted on the top of the barrel, and an intermittent rotating mechanism rotatably mounted inside the barrel. The intermittent rotating mechanism includes a fixed rod a rotatably mounted on the barrel and a stirring component. The stirring component includes a rod sleeve with several stirring blades, each with a brush plate inserted into its side wall. This bean washing machine's stirring mechanism incorporates an intermittent rotating mechanism, preventing continuous rotation that could break the beans. It also increases the surface area of the stirring blades, increasing the contact area with the beans during stirring and reducing the breakage rate. Furthermore, the brush plates clean the beans while simultaneously reducing the probability of breakage.
[0004] The above-mentioned method uses stirring blades and brushes to clean the beans inside the bean washing machine. When the cleaned beans are fed out, they are fed out through the discharge port. However, some beans will remain on the bottom surface of the inner wall of the barrel. Tools are needed to collect the beans remaining on the inner wall of the barrel. Collecting the beans is quite troublesome and takes a lot of time. Utility Model Content

[0025] The stirring assembly 13 includes a variable frequency motor 131. A connecting cylinder 134 is bolted to the bottom surface of the rotor of the variable frequency motor 131. A cleaning rod 132 is welded to the surface of the connecting cylinder 134. The cleaning rod 132 is divided into four groups, and the four groups of cleaning rods 132 surround the surface of the connecting cylinder 134. There are fifteen cleaning rods 132 in one group, and the fifteen cleaning rods 132 in the same group are distributed vertically.
[0026] A cleaning frame 133 is welded to the outer surface of the cleaning rod 132. A variable frequency motor 131 is installed in the middle of the sealing cover plate 11. The rotor of the variable frequency motor 131 drives the connecting cylinder 134, the cleaning rod 132 and the cleaning frame 133 to rotate, so as to clean the beans inside the cleaning tank 15.
[0027] A connecting plate 135 is movably connected to the bottom surface of the connecting cylinder 134. A scraping plate 136 is welded to the bottom surface of the connecting plate 135. A connecting block 139 is welded to the top surface of the connecting plate 135. A connecting cover plate 137 is movably connected to the top surface of the connecting block 139. The connecting cover plate 137 is movably connected to the surface of the cleaning rod 132. The connecting block 139 is movably connected to the surface of the cleaning rod 132. The connecting cover plate 137 is detached from the cleaning rod 132, which facilitates the disassembly and replacement of the connecting cover plate 137 and the connecting block 139, thereby increasing the service life of the connecting cover plate 137 and the connecting block 139.
[0028] A threaded rod 138 is welded to the bottom surface of the connecting cover plate 137. The threaded rod 138 is inserted into the front and rear ends of the connecting block 139. The nut rotates on the surface of the threaded rod 138. The threaded rod 138 locks and fixes the connecting block 139 and the connecting cover plate 137, making it convenient to disassemble and replace the scraper plate 136.
[0029] The feeding assembly 14 includes a second sealing cover plate 141, a connecting cylinder 134 movably connected to the middle position of the top surface of the second sealing cover plate 141, and a scraping plate 136 movably connected to the top surface of the second sealing cover plate 141. The second sealing cover plate 141 and the first sealing cover plate 11 limit the position of the connecting cylinder 134.
[0030] A vertical threaded rod 142 is welded to the bottom surface of the second sealing cover 141. The second sealing cover 141 is bolted to the bottom surface of the cleaning tank 15, and the first sealing cover 11 is bolted to the top surface of the cleaning tank 15. A sealed space is formed between the second sealing cover 141, the cleaning tank 15, and the first sealing cover 11. At the same time, a sealing ring is installed at the connection between the second sealing cover 141, the cleaning tank 15, and the first sealing cover 11 to prevent clean water from flowing out of the cleaning tank 15.
[0031] The bottom surface of the sealing cover plate 141 is welded with a discharge pipe 144. A sealing block 143 is inserted into the inner wall surface of the discharge pipe 144. The sealing block 143 is movably connected to the bottom end of the vertical threaded rod 142. The nut rotates on the surface of the vertical threaded rod 142 to block the space between the sealing block 143 and the discharge pipe 144, which can prevent the beans and water inside the cleaning tank 15 from flowing out.
[0032] When in use, pour beans and water into the feed pipe 12 so that the beans and water are inside the cleaning tank 15. Then start the variable frequency motor 131. The rotor of the variable frequency motor 131 drives the connecting cylinder 134 to rotate. The variable frequency motor 131 drives the connecting cylinder 134 to rotate intermittently to avoid damage to the beans by the cleaning frame 133 and the cleaning rod 132.
[0033] The connecting cylinder 134 drives the cleaning frame 133 and the cleaning rod 132 to rotate. The connecting cylinder 134 and the cleaning rod 132 clean the beans inside the cleaning tank 15 and remove the residue from the beans.
[0034] Rotate the nut to disengage it from the vertical threaded rod 142, thereby loosening the connection between the sealing block 143 and the vertical threaded rod 142. Pull the sealing block 143 downward to disengage it from the discharge pipe 144.
[0035] At this time, the water and beans inside the washing tank 15 move downward along the inner wall surface of the feeding pipe 144, thereby collecting the beans, but the surface of the sealing cover plate 141 still contains the washed beans.
[0036] Next, the variable frequency motor 131 is started. The rotor of the variable frequency motor 131 drives the connecting cylinder 134 to rotate. The connecting cylinder 134 drives the cleaning rod 132 downward. The cleaning rod 132 drives the connecting cover plate 137 and the connecting block 139 to rotate. The connecting block 139 drives the connecting plate 135 to rotate. The connecting plate 135 drives the scraping plate 136 to rotate. The scraping plate 136 scrapes the beans remaining on the surface of the sealing cover plate 141. The scraped beans move outward along the surface of the scraping plate 136 and enter the interior of the feeding pipe 144, thereby collecting the beans.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
