Sugarcane unloading equipment is a key piece of equipment for transferring sugarcane from transport vehicles to processing production lines. Its main function is to quickly and efficiently unload sugarcane from transport vehicles and transport it to designated locations.

[0003] After harvesting, sugarcane often contains a large number of impurities, such as soil, dead leaves, weeds, and stones. If these impurities are not removed in time, they will affect the quality and efficiency of sugarcane processing and may even damage the processing equipment. Therefore, a sugarcane unloading device that can remove impurities is proposed to solve the problems mentioned above. Utility Model Content

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figures 1-3 As shown, a sugarcane unloading device capable of removing impurities includes a support leg 1, a feeding mechanism 2 is provided at the upper end of the support leg 1, a first impurity removal mechanism 3 is provided on the right side of the feeding mechanism 2, and a second impurity removal mechanism 4 is provided on the right side of the first impurity removal mechanism 3.

[0026] Furthermore, the feeding mechanism 2 includes a first bracket 201 fixedly connected to the upper end of the support leg 1. A receiving hopper 202 is fixedly connected to the upper end of the first bracket 201. Two drive rollers 203 are rotatably connected to the inner side of the first bracket 201. A conveying steel belt 204 is sleeved on the outer surface of the drive rollers 203. A number of evenly distributed limiting protrusions 205 are fixedly connected to the outer surface of the conveying steel belt 204. A rotating shaft 206 is rotatably connected to the inner side of the receiving hopper 202. A number of evenly distributed separating rods 207 are fixedly connected to the outer surface of the rotating shaft 206.

[0027] Furthermore, the receiving hopper 202 is used to receive sugarcane unloaded from the transport vehicle. It is funnel-shaped and can guide the sugarcane to fall onto the conveyor belt 204. The conveyor belt 204 serves as the carrier for transporting sugarcane and is used to transport the sugarcane in the direction of the first impurity removal mechanism 3. The adjacent spacing of the limiting protrusions 205 is slightly larger than the diameter of a sugarcane, and the height is half the diameter of the sugarcane. It is used to limit the sugarcane and prevent it from rolling or slipping during the transport process. At the same time, it ensures that two adjacent limiting protrusions 205 can only limit one sugarcane at a time. The distance between the separating rod 207 and the limiting protrusions 205 is greater than the diameter of a sugarcane but less than the diameter of two sugarcanes. When multiple sugarcanes are stacked together and transported in the direction of the first impurity removal mechanism 3, the rotation of the separating rod 207 will push and remove the excess sugarcane stacked on top, avoiding excessive feeding at one time and affecting the processing effect of the subsequent impurity removal mechanism.

[0028] Furthermore, the first impurity removal mechanism 3 includes a second support 301 fixedly connected to the right end of the first support 201. Several evenly distributed gear rollers 302 are rotatably connected to the inner side of the second support 301. A sugarcane leaf separation box 303 is fixedly connected to the upper end of the second support 301. A discharge pipe 304 is connected to the upper end of the sugarcane leaf separation box 303. A discharge outlet 307 is provided through the rear end of the discharge pipe 304. The discharge outlet 307 is connected to the discharge pipe 304 and the interior of the sugarcane leaf separation box 303.

[0029] Furthermore, a drive shaft 305 is fixedly connected to the inner top of the discharge pipe 304, and a sugarcane leaf separating fan 306 is fixedly connected to the lower end of the drive shaft 305.

[0030] Furthermore, the teeth on adjacent gear rollers 302 are staggered, and the gap between adjacent gear rollers 302 is small, to prevent sugarcane from getting caught between the two gear rollers 302.

[0031] Furthermore, the sugarcane conveyed by the feeding mechanism 2 will finally fall onto the gear roller 302, and be conveyed to the direction of the second impurity removal mechanism 4 through the gear roller 302. When the sugarcane passes through the gear roller 302, the staggered teeth of the gear roller 302 will peel off the sugarcane leaves from the surface of the sugarcane. The drive shaft 305 drives the sugarcane leaf separation fan 306 to rotate, generating a strong airflow that can suck the sugarcane leaves and other light impurities separated by the gear roller 302 into the sugarcane leaf separation box 303, and discharge them through the discharge outlet 307 of the discharge pipe 304, thus achieving efficient sugarcane leaf separation and removal.

[0032] Furthermore, the second impurity removal mechanism 4 includes a third support 401 fixedly connected to the right end of the second support 301. A sieve plate 402 is fixedly connected to the inner side of the third support 401. A plurality of evenly distributed sieve holes 403 are opened through the upper end of the sieve plate 402. A plurality of evenly distributed brush rollers 404 are rotatably connected to the upper end of the inner side of the third support 401 near the sieve holes 403. A spray plate 405 is fixedly connected to the top end of the inner side of the third support 401. A plurality of evenly distributed nozzles 406 are connected to the lower end of the spray plate 405.

[0033] Furthermore, the interior of the spray plate 405 is a hollow structure.

[0034] Furthermore, the upper end of the spray plate 405 is connected to a water supply pipe 407, and the other end of the water supply pipe 407 passes through the upper end of the third support 401 and extends to the upper side of the third support 401.

[0035] Furthermore, a water collection tank 408 is fixedly connected to the inner side of the third support 401 below the sieve plate 402.

[0036] Furthermore, the sugarcane conveyed by the gear roller 302 falls onto the screen plate 402. The distance between the screen plate 402 and the brushes on the brush roller 404 is smaller than the diameter of the sugarcane. The sugarcane falling onto the screen plate 402 will be pushed to the right side of the screen plate 402 under the action of the brush roller 404. The water supply pipe 407 is connected to an external water source. Water is transported to the spray plate 405 through the water supply pipe 407 and sprayed out through the nozzles 406, which can clean the surface of the sugarcane. At the same time, the friction between the brush roller 404 and the sugarcane can improve the cleaning effect.

[0037] Furthermore, the rotation of the drive roller 203, rotating shaft 206, drive shaft 305, gear roller 302 and brush roller 404 are all driven by a motor. For a drive with multiple shafts or rollers, a connecting shaft can be set at one end of the multiple rollers or shafts, and then a gear can be connected through the connecting shaft. Then, a chain can be set on the surface of the gear for transmission, thereby achieving the drive.

[0038] Working principle: During operation, park the sugarcane transport vehicle next to the receiving hopper 202 of the equipment, then pour the sugarcane into the receiving hopper 202. Start the equipment; the feeding mechanism 2 will begin operation. The drive roller 203 will drive the conveyor belt 204 to transport the sugarcane towards the first impurity removal mechanism 3. The limiting protrusion 205 ensures orderly single-stalk transport of sugarcane. The separating rod 207 will promptly remove excess sugarcane. After the sugarcane enters the first impurity removal mechanism 3, the gear roller 302 rotates to peel off the sugarcane leaves, and the sugarcane leaf separating fan 306 sucks the sugarcane leaves into the sugarcane. The sugarcane separated from the leaves 303 is discharged through the discharge pipe 304. The sugarcane after leaf separation enters the second impurity removal mechanism 4 and falls onto the screen plate 402. Under the action of the brush roller 404, it is pushed to the right. Particulate impurities such as soil fall through the screen holes 403. The spray structure composed of the spray plate 405, nozzles 406 and water supply pipe 407 can clean the surface of the sugarcane and further remove residual impurities. The wastewater and impurities after cleaning fall into the collection pool 408. The cleaned sugarcane is discharged from the right side of the second impurity removal mechanism 4.
