[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Example 1, by Figure 1-2This utility model relates to an automatic sorting device in the process of washing beans, including a washing tank 1. The washing tank 1 has a hollow frame 5 inside, and an installation mechanism 3 is provided on the outside of the hollow frame 5. An inclined plate 6 is fixedly connected to the inner bottom wall of the washing tank 1. A slag discharge port 7 is provided on the outside of the washing tank 1 near the bottom. A water injection pipe 8 is fixedly connected to the outside of the washing tank 1. A filter mechanism 2 is provided inside the washing tank 1. A waste outlet 9 is provided on the outside of the washing tank 1. Both the slag discharge port 7 and the waste outlet 9 are provided with sealing plates. The water injection pipe 8 is located higher than the hollow frame 5. And below the waste outlet 9, the filtration mechanism 2 includes a bracket 201 located inside the cleaning tank 1. Two filter frames 209 are symmetrically fixedly connected to the bracket 201. The bottom of each filter frame 209 is provided with multiple filter holes 2010. Two guide pillars 2011 are symmetrically fixedly connected inside the cleaning tank 1. A guide plate 203 is movably sleeved between the two guide pillars 2011. The bracket 201 is located on top of the guide plate 203. A top block 2012 is fixedly connected to the top of the guide plate 203. The bracket 201 is sleeved on the outside of the top block 2012. A positioning plate 2013 is fixedly connected to the top of the guide plate 203. Two bolt L-shaped plates 2014 are symmetrically installed between the positioning plate 2013 and the guide plate 203. Through the cooperation between the positioning plate 2013 and the bolt L-shaped plates 2014, the bracket 201 can be disassembled from the top of the guide plate 203, thereby facilitating the processing of larger impurities such as stones in the filter frame 209. A 2015 is fixedly installed on the top of the cleaning tank 1. A stirring motor 207 is fixedly installed on the 2015. A [missing information - likely a device or component] is fixedly connected to the stirring motor 207. A stirring shaft 208 is located between two filter frames 209. Multiple stirring rods 202, each located below the two filter frames 209, are fixedly connected to the outside of the stirring shaft 208. An outer ring 206 is fixedly sleeved on the outside of each of the two guide pillars 2011. A spring 205 is fixedly connected between each of the two outer rings 206 and the guide plate 203. The two springs 205 are respectively sleeved on the outside of the two guide pillars 2011. An eccentric block 204 is fixedly sleeved on the outside of the stirring shaft 208. The eccentric block 204 and the guide plate 203 are at the same height.
[0025] In operation, beans are first poured into two filter frames 209 and filtered through the filter holes 2010, allowing larger impurities such as stones to remain within the filter frames 209. Then, the stirring motor 207 is started, driving the stirring shaft 208 to rotate and causing the eccentric block 204 to rotate and impact the guide plate 203. Under the elastic force of the two springs 205, the guide plate 203 moves back and forth along the two guide columns 2011, preventing the filter holes 2010 from becoming clogged and improving filtration efficiency. Then, water is injected into the washing tank 1 through the water inlet pipe 8. The water flow moves the beans, causing light impurities such as empty shells to float with the water flow to the waste outlet 9 for discharge, while heavy impurities such as mud and sand settle and are discharged from the slag outlet 7 through the inclined plate 6, achieving thorough removal of impurities. When the stirring shaft 208 rotates, it drives the stirring rod 202 to rotate, stirring the water and beans, finally achieving thorough cleaning of the beans.
[0026] Specifically, by Figure 5 The installation mechanism 3 includes an installation plate 301 located outside the cleaning tank 1. A sealing gasket 302 and an insert plate 303 are fixedly connected to the outside of the installation plate 301. The sealing gasket 302 is sleeved on the outside of the insert plate 303 and abuts against the cleaning tank 1. By setting the sealing gasket 302, the sealing performance of the cleaning tank 1 can be guaranteed. The cleaning tank 1 is provided with an installation groove 4. The insert plate 303 is inserted into the installation groove 4 and fixedly connected to the hollow frame 5. Two side plates 3011 are symmetrically fixedly connected to the outside of the cleaning tank 1. The installation plate 301 is sleeved on the outside of the two side plates 3011. A double-acting screw 3010 is rotatably connected to the installation plate 301. A turntable 30 is fixedly installed on the middle of the outer side of the double-acting screw 3010. 9. Two nuts 308 are symmetrically threaded on the outer side of the double-acting screw 3010. Insert rods 307 are fixedly connected to the side of the two nuts 308 that are far apart from each other. Insert rings 306 are fixedly connected to the side of the two side plates 3011 that are close to each other. The two insert rods 307 are respectively inserted into the two insert rings 306. The mounting plate 301 is provided with a sliding groove 304. The bottom of the two nuts 308 is fixedly connected to a slider 305. The two sliders 305 are slidably connected to the sliding groove 304. Through the cooperation between the sliders 305 and the sliding groove 304, the nuts 308 can be guided. When the double-acting screw 3010 rotates, the nuts 308 can move along the length direction of the double-acting screw 3010.
[0027] In use, first, the hollow frame 5 is passed through the mounting groove 4 and placed inside the washing box 1, so that the mounting plate 301 is fitted over the outside of the two side plates 3011 until the insert plate 303 is inserted into the mounting groove 4. At the same time, the sealing gasket 302 is in contact with the washing box 1. Then, the turntable 309 is rotated, which drives the bidirectional lead screw 3010 to rotate and drives the two lead nuts 308 to move horizontally. At the same time, the two insert rods 307 move away from each other until they are inserted into the two insert rings 306 respectively, fixing the mounting plate 301 to the two side plates 3011, thus realizing the installation and fixation of the hollow frame 5. Finally, the beans are collected.
