Description

Technical Field

[0001] The invention relates to the technical field of plum sorting, and in particular to an all-in-one plum cleaning and sorting machine. Background Art

[0002] Plum is the fruit of the genus Prunus in the Rosaceae family. Plum tastes sour, and can promote the secretion of gastric acid and gastric digestive enzymes, and promote gastrointestinal motility, thus improving appetite and promoting digestion. It is especially effective for those who lack gastric acid and feel bloated after eating. At the same time, plum contains a variety of nutrients, has the effect of beautifying and lubricating the skin, and has a very high content of antioxidants, so it is called a "super fruit" for anti-aging and disease prevention.

[0003] During the growth process, plums vary in size, shape, color, etc. due to the influence of various factors such as light and nutrient absorption. In order to improve the efficiency of plum storage and transportation, the picked plums are sorted by size, which can make better use of space during the packaging and storage of plums, improve the space utilization rate of packaging boxes, and thus reduce transportation costs; However, plums grow in orchards where there are insects such as aphids and fruit flies. Aphids secrete honeydew, which drips on the surface of plums. As the sorting equipment sorts the plums, the honeydew on the surface of the plums will continue to accumulate on the sorting equipment. Since the honeydew has a certain viscosity, the plums that should have fallen and been sorted will stick to the conveyor belt due to the viscosity of the honeydew, thereby affecting the sorting accuracy and efficiency of the plums.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The tensioning assembly pushes the tensioning plate to make the tensioning roller properly tension the conveyor belt. At the same time, the tensioning roller drives the cleaning roller through gear 1 and gear 2 to scrape the honeydew on the conveyor belt, thereby preventing the honeydew from accumulating on the conveyor belt. This causes the plums that should have been separated from the conveyor belt and sorted to stick to the conveyor belt due to the viscosity of the honeydew, thereby improving the sorting accuracy and efficiency of the plums. At the same time, the conveyor belt is cleaned, avoiding the cleaning process of the equipment after plum sorting, reducing labor and improving the convenience of equipment use. 2. By setting a tensioning assembly, nut 2 can be used to drive the screw to rotate, nut 1 is threadedly connected to the screw, and then the limit strip is used to limit the nut 1, so that by rotating nut 2 and the screw, nut 1 and spring 2 can be further compressed, so that the reset elastic force applied by spring 2 to tensioning cylinder 2 is increased, thereby adjusting the tensioning force applied by the tensioning roller to the conveyor belt, ensuring the tension of the conveyor belt, and improving the sorting effect of plums on the conveyor belt. Furthermore, the tension of the conveyor belt is ensured by the tensioning assembly, and the contact pressure between the conveyor belt and the tensioning roller will also increase, thereby ensuring that the conveyor belt can drive the tensioning roller to rotate during the displacement process, and then the spring pair of elastic plates are used to push up, so that the cleaning roller can continuously remove the honey dew on the conveyor belt, further improving the sorting effect of plums; 3. The synchronous ring is driven to rotate by the guide roller, and the synchronous plate is in contact with the trigger plate, so that the synchronous plate can push the main plate through the trigger plate, and then the slider on the support rod slides along the inclined groove, causing multiple toggle plates to shift alternately, and then the plums on the conveyor belt are toggled by the rubber tentacles, so that the posture of the plums on the conveyor belt is adjusted, so that plums with irregular contours and similar sizes can be sorted together, thereby improving the sorting accuracy of plums; 4. The piston rod is driven by the main board, and the gas in the piston cylinder is passed into the drain cylinder by the piston plate, so that the alkaline solution in the drain cylinder is introduced into the pressure box. The spring 4 is used to press the pressure plate, and the alkaline solution entering the pressure box cannot be quickly discharged from the water spray tank, so that the pressure in the pressure box increases, and the spring 4 is deformed, causing the alkaline solution to be sprayed out from the water spray tank at a high speed, thereby flushing the conveyor belt. At the same time, the alkaline solution will react with the honey dew on the conveyor belt, reducing the viscosity of the honey dew and improving the cleaning effect of the cleaning roller on the conveyor belt; 5. By setting up a reflux pipe, when too much water flows into the pressure box, the alkaline solution in the pressure box can return to the water storage tank through the reflux pipe, avoiding excessive pressure inside the pressure box, resulting in reduced sealing and leakage of alkaline solution.

[0030] The tensioning assembly 23 includes a tensioning cylinder 231, a tensioning cylinder 232 is slidably arranged inside the tensioning cylinder 231, a connecting cover 233 is arranged at one end of the tensioning cylinder 232, a connecting seat 1 is hingedly arranged at the end of the tensioning cylinder 231 away from the tensioning cylinder 232, the connecting seat 1 is connected to the base plate 21, the connecting cover 233 is arranged at the end of the tensioning cylinder 232 away from the tensioning cylinder 231, a connecting seat 2 is hingedly arranged on the connecting cover 233, and the connecting seat 2 is connected to the tensioning plate 22.

[0031] A screw rod 234 is rotatably arranged in the tensioning cylinder 1 231, a limit strip 235 is arranged in the tensioning cylinder 1 231, a nut 1 236 is threadedly connected to the screw rod 234, a nut 237 is arranged on the screw rod 234, one end of the screw rod 234 away from the tensioning cylinder 1 231 passes through the tensioning cylinder 232, the limit strip 235 is symmetrically arranged on both sides of the screw rod 234, the nut 1 236 and the nut 237 are hexagonal nuts, and the nut 1 236 is arranged on the screw rod 234. One end of the rod 234 is located in the area of ​​the limit strip 235. The two limit strips 235 can limit the nut 1 236, so that the nut 1 236 cannot rotate. The nut 237 is fixedly connected to the screw rod 234, and the nut 237 is arranged at the end of the screw rod 234 away from the nut 1 236. A spring 2 is sleeved on the outside of the screw rod 234, and one end of the spring 2 is in contact with the nut 1 236, and the end of the spring 2 away from the nut 1 236 is in contact with the tensioning tube 2 232.

[0032] During use, first start the motor 1, the output shaft of the motor 1 rotates and drives the guide roller 11, and then the rotation of the guide roller 11 drives the conveyor belt 15 to rotate. At this time, the plums on the belt line will be transported to the area close to the guide roller 11, and then the plums will fall onto multiple conveyor belts 15. Since the plums are spherical, the plums will roll into the gap between two adjacent conveyor belts 15 at this time. With the rotation of the output shaft of the motor 1, the plums between the two adjacent conveyor belts 15 will be driven by the conveyor belt 15 and move from the area of ​​the guide roller 11 to the direction of the guide roller 2 12; As the plums gradually approach the area of ​​the guide roller 11 toward the area of ​​the guide roller 2 12, the distance between two adjacent conveyor belts 15 will continue to increase. When the diameter of the plums on the conveyor belt 15 is at least equal to the distance between the two adjacent conveyor belts 15, the plums on the conveyor belt 15 will pass through the gap between the two conveyor belts 15 under the action of their own gravity, and then the plums of different sizes on the conveyor belt 15 will successively fall off the conveyor belt 15 under the action of gravity, and the plums of similar sizes will fall into the same collection bucket, and then the plums will be selectively classified according to the size rules; Then the plums of similar size will fall into the same cleaning tank, and then the motor 2 will be started, and the output shaft of the motor 2 will drive the cleaning shaft, so that the cleaning bristles on the cleaning shaft will brush the surface of the plums; When the guide roller 11 drives the conveyor belt 15 to move, the spring 2 pushes the nut 1 236 and the tensioning cylinder 232, so that the distance between the tensioning cylinder 1 231 and the tensioning cylinder 232 increases, and the tensioning plate 22 rotates around the connection between it and the bottom plate 21, so that the tensioning roller 221 contacts and pushes the conveyor belt 15, and then the tensioning roller 221 properly tensions the conveyor belt 15; As the conveyor belt 15 is driven by the guide roller 11 to move, the conveyor belt 15 will drive the tension roller 221 to rotate. At this time, the tension roller 221 rotates in the moving direction of the conveyor belt 15, and the tension roller 221 drives the gear 1 222 to rotate synchronously. The gear 1 222 will drive the gear 2 242 to rotate. At this time, the gear 2 242 will drive the cleaning roller 241 to rotate in the opposite direction to the moving direction of the conveyor belt 15. The spring 1 pushes the elastic plate 24, so that the rubber scraper on the cleaning roller 241 contacts the conveyor belt 15 and scrapes the honey dew on the surface of the conveyor belt 15. After the conveyor belt 15 has been used for a period of time, the tension of the conveyor belt 15 will decrease. At the same time, the restoring elastic force of the spring 2 will also decrease under long-term compression. At this time, by rotating the nut 237, the screw 234 will rotate synchronously with the nut 237. At this time, the nut 1 236 will normally rotate synchronously with the screw 234, but because the limit bar 235 limits the nut 1 236, the nut 1 236 cannot rotate synchronously with the screw 234. Therefore, when the screw 234 rotates, the nut 1 236 will move along the limit bar 235 toward the direction of the tensioning tube 232, and then the distance between the nut 1 236 and the tensioning tube 232 will decrease, and the spring 2 will be further compressed, causing the tensioning tube 232 to push the tensioning plate 22, so that the tensioning roller 221 further tensions the slack conveyor belt 15.

A plurality of toggle plates 33 are alternately arranged left and right. A rubber tentacle is arranged in an array on one side of the toggle plates 33 close to the frame 1.

During the rotation of the synchronous ring 37, the synchronous plate 371 will contact the trigger plate 38. Then, during the rotation of the synchronous plate 371 following the synchronous ring 37, the synchronous plate 371 will push the trigger plate 38. At this time, the main board 31 will drive the slide plate 32 to make the slide plate 32 slide linearly on the frame 1, and the main board 31 will move toward the direction of the guide roller 2 12. At this time, the spring 3 is deformed and compressed, and the telescopic rod 34 goes deep into the main board 31, and then the telescopic rod 34 drives the support rod 35 to move synchronously. At this time, the slider 36 slides along the inclined groove, and the support rod 35 pushes the multiple toggle blocks to move toward the direction of the telescopic rod 34; When the synchronous plate 371 rotates to separate from the trigger plate 38, the restoring elastic force of the spring 3 pushes the elastic block, so that the slide plate 32 is reset, and the main plate 31 is reset synchronously with the slide plate 32. At this time, the telescopic rod 34 gradually extends out of the main plate 31, and the slider 36 slides along the inclined groove and resets, and then the multiple toggle plates 33 move away from each other and reset; During the displacement of the toggle plate 33 , the rubber tentacles of the toggle plate 33 come into contact with the plums on the conveyor belt 15 . The displacement of the toggle plate 33 causes the rubber tentacles to toggle the plums, thereby changing the posture of the plums on the conveyor belt 15 .

During this process, the pressure in the drain cylinder 46 increases, and the alkaline solution in the drain cylinder 46 pushes the opening and closing plate 471, causing the opening and closing plate 471 to tightly seal the connecting pipe 47, so that the alkaline solution in the drain cylinder 46 cannot enter the water storage tank 48 through the connecting pipe 47, and then enter the pressure box 42; When the main board 31 drives the piston rod 44 to move toward the direction of the guide roller 11, the piston plate will be reset synchronously with the piston rod 44, and the gas entering the drain cylinder 46 will return to the piston cylinder 45 through the air pipe. At this time, negative pressure will be generated in the drain cylinder 46, and the drain plate 461 will move toward the direction of the air pipe. At this time, the opening and closing plate 471 will rotate under the action of the negative pressure, and the alkaline solution in the water tank 48 will enter the drain box through the connecting pipe 47. When the pressure in the drain box reaches equilibrium, the opening and closing plate 471 will re-block the connecting pipe 47 under the action of the reset elastic force of the torsion spring; As the alkaline solution is continuously introduced into the pressure box 42, the pressure in the pressure box 42 is continuously increased, and the alkaline solution in the pressure box 42 is sprayed out through the water spraying slot 411 on the water spraying box 41. The alkaline solution sprayed out from the water spraying slot 411 contacts the conveyor belt 15, and the alkaline solution washes the dirt on the surface of the conveyor belt 15. At the same time, the alkaline solution reacts with the honey dew, causing the viscosity of the honey dew on the conveyor belt 15 to decrease, thereby further cleaning the honey dew on the conveyor belt 15. When the pressure in the pressure box 42 is too high, the spring four is deformed, and the pressure plate 421 will gradually shift to pass over the connection between the reflux pipe 43 and the pressure box 42. At this time, the alkaline solution in the pressure box 42 will flow back to the water storage tank 48 through the one-way valve one and the reflux pipe 43. When the pressure in the pressure box 42 decreases, the pressure plate 421 will gradually return to its original position under the action of the restoring elastic force of the spring four. When the pressure plate 421 passes over the connection between the reflux pipe 43 and the pressure box 42 again, the alkaline solution in the pressure box 42 will not flow back to the water storage tank 48.
