[0002] Grain transportation refers to the transfer and circulation of grain between various geographical regions during the sales and processing of grain. Grain impurity removal refers to the process of removing impurities, foreign objects, and other unwanted substances in order to improve the quality and purity of grain. Grain impurity removal is crucial for ensuring grain quality and food safety. It can reduce the loss of grain during storage and prevent problems such as heating and mildew caused by impurities. At the same time, high-quality grain is also more conducive to subsequent processing and utilization.

[0003] When the existing grain transportation equipment transports grain, it cannot remove impurities from the grain and can only use a dedicated impurity removal device for impurity removal, which is cumbersome to operate. Moreover, the height of the existing grain feeding equipment is fixed and cannot flexibly adjust the discharge port according to different situations, resulting in limited usage range.

[0004] Therefore, there is a need for a grain feeding device with an impurity removal function. This device can remove impurities from the fed grain, achieve alternating filtration and impurity removal of the grain, improve the grain impurity removal efficiency while ensuring the impurity removal effect; this device can comb the impurities in the grain during grain impurity removal to ensure that the impurities in the grain can be completely filtered out, improving the grain cleanliness; this device can remove stones from the grain after impurity removal is completed, further improving the grain cleanliness; this device adopts a method of freely installing the grain feeding outlet, effectively improving the flexibility of the device while improving the grain transportation efficiency.

[0041] Working principle: The equipment can clean the fed grain, and achieve alternate filtering and impurity removal of the grain, improving the grain impurity removal efficiency while ensuring the impurity removal effect; when the equipment removes impurities from the grain, it can comb the sundries in the grain to ensure that the sundries in the grain can be completely filtered out, improving the grain cleanliness; the equipment can perform stone removal on the grain after impurity removal, further improving the grain cleanliness; the equipment adopts the method of freely installing the grain feeding outlet, effectively improving the flexibility of equipment operation while improving the grain transportation efficiency.

[0042] First, manually put the grains to be purified onto conveyor belt 1, and the conveyor belt 1 slowly transports the grains. Then, when purifying and filtering the grains, motor I 209 starts, driving the stopper 210 to rotate clockwise. The short rod on the stopper 210 toggles the outer end of the toggling rod 221. At this time, the hook at the inner end of the toggling rod 221 disengages from the restriction of the short protrusion 208 and quickly returns to its original position. At this time, the spring behind the cross plate 206 pulls the cross plate 206 to move to the right until the block on the lower side of the cross plate 206 contacts and engages with the convex rod at the lower end of the first bracket 205. At this time, the two racks on the cross plate 206 drive the gears on the shafts of the two purifiers 203 to rotate 90°. At this time, the filtering rake on the front purifier 203 rotates counterclockwise from the upper end to the lower end. At this time, the outer end of this filtering rake is inserted into the grains on the conveyor belt 1 to filter the grains passing through it. The filtering rake on the rear purifier 203 rotates clockwise from the lower end to the upper end. At this time, the inclined plate on this purifier 203 is located at the upper opening of the corresponding collection box 204. The sundries on the filtering rake of this purifier 203 enter the collection box 204 along the inclined plate for collection. Then, motor I 209 continues to drive the stopper 210 to rotate clockwise. The long rod on the stopper 210 rotates to contact the long protrusion 207 and pushes the long protrusion 207 to move to the left. At this time, the long protrusion 207 drives the cross plate 206 to move back to the left until the short protrusion 208 engages with the hook on the toggling rod 221 again. At this time, the two racks on the cross plate 206 drive the gears on the shafts of the two purifiers 203 to rotate counterclockwise by 90°. At this time, the filtering rake on the front purifier 203 rotates clockwise from the lower end to the upper end. At this time, the inclined plate on this purifier 203 is located at the upper opening of the corresponding collection box 204. The sundries on the filtering rake of this purifier 203 enter the collection box 204 along the inclined plate for collection. The filtering rake on the rear purifier 203 rotates counterclockwise from the upper end to the lower end. The outer end of this filtering rake is inserted into the grains on the conveyor belt 1 to filter the grains passing through the filtering rake. In this way, the grains on the conveyor belt 1 are alternately filtered and purified, improving the grain purification efficiency while ensuring the purification effect. While removing impurities from grains, the impurities in the grains are combed. During the combing process, the inner end of the Z-shaped rod 215 is driven to rotate by the motor I 209. The inner end of the Z-shaped rod 215 drives the outer end of the Z-shaped rod 215 to rotate. The outer end of the Z-shaped rod 215 drives one end of the long connecting rod 216 to move up and down. This end of the long connecting rod 216 drives the first rectangular block 213 to slide up and down in the long vertical groove on the side of the cross-shaped frame 212. At the same time, the outer end of the Z-shaped rod 215 drives the other end of the long connecting rod 216 to move left and right. This end of the long connecting rod 216 drives the second rectangular block 214 to slide left and right in the long horizontal groove on the side of the cross-shaped frame 212. The second rectangular block 214 drives the long rack 217 to move left and right. The long rack 217 drives the gear I 218 and the gear II 219 to rotate simultaneously. The gear I 218 and the gear II 219 respectively drive the screws in the two screw slider groups 220 to rotate. The screws in the screw slider groups 220 drive the U-shaped frames at the lower ends of the sliders in the screw slider groups 220 to move left and right in the grains on the conveyor belt 1, shifting the impurities in the grains to a horizontal position, facilitating the filtering rake on the impurity remover 203 to filter and pick them up; The grains after impurity removal enter the stone remover 301 from the discharge end of the conveyor belt 1. The stone remover 301 removes stones from the grains to further ensure the cleanliness of the grains. The grains after stone removal enter the discharge box on the side of the stone remover 301. Then, the operator places the discharger 303 at a suitable position according to the need. Then, the grains in the discharge box on the side of the stone remover 301 sucked by the grain suction device 302 move along the telescopic hose at the rear of the discharger 303 and are discharged by the discharger 303. The discharger 303 is placed manually in a free manner, effectively improving the flexibility of the equipment while enhancing the grain transportation efficiency.
