Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sugarcane conveying technology, specifically relating to a sugarcane raw material self-unloading and impurity removal conveying system. Background Technology
[0002] After harvesting, some sugarcane is sold in the market, while the rest is sent to sugar mills for juice extraction and sugar production. Currently, sugarcane is harvested primarily by hand and by machine. Existing mechanical harvesting mainly uses combine harvesters to cut the entire sugarcane stalk, while some machines have a cutting function, segmenting the stalk during harvesting for easier transport. Regardless of the harvesting method, sugarcane always carries mud and sand with it, necessitating impurity removal during sugar production—specifically, after crushing the sugarcane. However, removing mud and sand after crushing also removes some sugar, reducing sugar yield and quality. Therefore, impurity removal is necessary before the sugarcane is unloaded at the sugar mill.
[0003] In existing technologies, impurities are mainly removed from sugarcane during unloading and conveying using screen bars, screen plates, or blowers. For example, patent publication number CN108569574B discloses a self-unloading conveying and impurity removal system for sugarcane raw materials, and patent publication number CN110743794A discloses a sugarcane impurity removal system. These methods are primarily for removing impurities from the entire sugarcane stalk and are not suitable for sugarcane segments. Therefore, it is necessary to design a self-unloading impurity removal and conveying system for sugarcane raw materials specifically for sugarcane segments. Utility Model Content

[0007] As a further improvement to the technical solution, a drain port is provided at the bottom of the impurity removal box.
[0008] As a further improvement to the technical solution, the first tube is located at the horizontal end of the impurity removal box near the mesh conveyor.

[0012] As a further improvement to the technical solution, a baffle is provided above the conveyor belt of the second sugarcane conveyor; the baffle is vertically arranged; and the bottom of the baffle is spaced apart from the conveyor belt of the second sugarcane conveyor.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This application utilizes a spray nozzle to effectively clean the mud and sand from sugarcane segments, facilitating subsequent juice extraction and sugar production. During unloading, the truck enters a self-unloading device, which tilts the truck, dumping the sugarcane segments onto the conveyor belt of the first conveyor. The first conveyor then transports the sugarcane segments to a cleaning device. The segments fall from the top of the first conveyor into the feed hopper and into the cleaning box. Inside the cleaning box, a mesh conveyor starts, moving the sugarcane segments towards the tilted end. During this movement, a pump is activated, and the pump... Water is supplied from the second pipe to the first pipe. The water enters the first pipe and is sprayed out from the nozzle. The sprayed water washes the sugarcane segments on the mesh conveyor, washing away the mud and sand. The washed water is discharged from the drain port on the impurity removal box. When the sugarcane segments move to the inclined end of the mesh conveyor, they are pushed upward by the push plate, and at the same time, the fan blows air towards them to dry the water stains on the sugarcane segments. After the sugarcane segments move to the top of the inclined end of the mesh conveyor, they are discharged from the discharge port of the impurity removal box and fall onto the second sugarcane conveyor, where they are continued to be transported forward for subsequent processes.
