Description

Technical Field

[0001] The utility model relates to sugarcane processing equipment, in particular to a sugarcane flap impurity removal system. Background Art

[0002] Traditional sugarcane flap desilting systems primarily consist of a flap platform, a conveyor, a pre-storage bin, a leveler, a vibrating screen, and a scatterer. After leveling, vibrating, and scattering, the sugarcane enters the next process. In recent years, the use of combined and step-by-step sugarcane harvesters has increased annually, bringing with it an increasing amount of sediment. This crushing season, approximately 43,000 tons of sugarcane were harvested, and a spot check revealed a dry filter mud to sugarcane ratio of 1.78% (normally around 1%), an estimated 10,000 tons more than normal. Due to inadequate desilting by the flap desilting system, large amounts of sediment enter the production process, causing subsequent production difficulties and significant wear and tear on the crushing equipment. Sediment deposited in the juice tank can easily breed bacteria and remove sugar. The entry of sediment into the sugar production process presents significant disadvantages and potential risks, necessitating the removal of sediment as soon as possible within the crushing flap desilting system. However, sugarcane purchased directly from individual farmers through traditional procurement channels contains far less mud than sugarcane harvested using combined or step-by-step harvesters. Furthermore, sugarcane acquired through traditional procurement channels, when processed in existing waste removal systems, can achieve a standard amount of filtered mud. Therefore, improvements to these traditional waste removal systems are necessary. Utility Model Content

[0014] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0015] 1. Through the design of two scatterers, after the sugarcane is leveled by the leveler, the soil and broken sugarcane on the sugarcane can be effectively removed through two scattering and impurity removal processes, thereby reducing the sand content of the sugarcane.

[0016] 2. A steerable conveyor 4 is set on the conveyor between the two scatterers.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1-5As shown, a sugarcane flap impurity removal system includes a flap platform 1, a conveyor 2, a pre-storage box 3, a leveler 4, a vibrating screen 5, a scatterer 7, a scatterer 2 10, and a drum screen 12. The flap platform 1 is arranged on both sides of the conveyor 2, the pre-storage box 3 is placed at the output end of the conveyor 2, the leveler 4 is installed on one side of the pre-storage box 3, and its leveling blade 41 extends to the pre-storage box 3. A vibrating screen 5 is provided below the leveler 4. One side of the vibrating screen 5 is connected to the scatterer 7 via the conveyor 2 6. The scatterer 17 is connected to the scatterer 2 10 via the conveyor 3 8. The output end of the scatterer 2 10 is provided with a conveyor 5 11, and the output end of the conveyor 5 11 is connected to the drum screen 12. Conveyors 3 8 and 5 11 are both provided with a conveyor 4 9 that divides them into two sections. A steering mechanism 13 is installed below the conveyor 4 9, and a conveyor 6 14 is provided between the two conveyors 4 9. With this design, after the sugarcane is leveled by the leveler 4, two rounds of scattering and impurity removal are performed, effectively removing dirt and broken sugarcane from the sugarcane, thereby reducing the sand content of the sugarcane. Furthermore, considering that different batches of sugarcane contain different amounts of dirt, batches with less dirt can be scattered once. Therefore, this embodiment provides a steerable conveyor 29 9 on the conveyor between the two scatterers. When only one scattering is required, the scattering of the sugarcane is directly fed to the drum screen 12 via the conveyor 29 9 and the conveyor 6 14. This improves the flexibility of the impurity removal system and avoids the high energy consumption associated with the simultaneous use of two scatterers. The drum screen 12 screens the sugarcane after the second scattering, which is more effective than a vibrating screen in breaking up dirt. This facilitates the breaking of large clumps of dirt and the removal of dirt from the ends of the sugarcane, significantly improving the desilting effect.

[0028] In this embodiment, the steering mechanism 13 comprises a support 131, an elevator 132, and a motorized rotary table 133. The support 131 is mounted below the conveyor 299, while the elevator 132 is mounted below the support 131, which is then mounted on the motorized rotary table 133. To steer the conveyor 299, the elevator 132 first operates to move the conveyor 299 downward to a position where it no longer interferes with the conveyor 38 or conveyor 511. The motorized rotary table 133 is then activated to steer the conveyor 299, and the elevator 132 is then reset. This completes the steering of the conveyor 299.

[0029] The present invention is provided with at least three lifters 132. In this embodiment, four lifters 132 are used to ensure the stability of the conveyor 29 9 during movement and operation. The lifters 132 are hydraulic cylinders or electric telescopic rods, and hydraulic cylinders are preferably used in this embodiment.

[0030] As for the installation setting of the drum screen 12, it is installed at the output end of the conveyor 5 11 with an angle downward, so as to facilitate the automatic removal of impurities from the sugarcane and also enable the sugarcane to be automatically unloaded, thereby improving work efficiency.

[0031] After being leveled, vibrated, and scattered, the sugarcane still contains some large pieces of dirt. This dirt is relatively hard and won't break apart and be sieved out like softer dirt through ordinary vibration. To address this, the drum screen 12 of this embodiment is equipped with multiple partitions 121 arranged toward the center of the drum. A mud crushing assembly consisting of multiple cones 122 is fixed between adjacent partitions 121. The partitions 121 bring the sugarcane and the dirt to the top of the drum screen 12, where they fall freely and impact the cones 122 below. This crushes the dirt and achieves better mud removal.

[0032] Furthermore, the cones 122 in two adjacent mud crushing assemblies are staggered to increase the collision rate between the soil and the cones 122. The tips of the cones 122 are hemispherical in shape to avoid the problem of sugarcane being inserted into the cones due to the sharp tips of the cones 122.

[0033] During sugarcane impurity removal, the thickness of the sugarcane smoothed by the smoothing machine 4 is correlated with the vibration-throwing and impurity removal process. A thinner thickness results in better impurity removal. Therefore, this embodiment incorporates an extended blade 42 on the smoothing blade 41. For example, if the existing smoothing machine has a rotation diameter of 1.5 meters, extending the smoothing blade by 0.1 meters can throw the sugarcane farther and over a wider area, thereby reducing the thickness of the smoothed sugarcane layer and facilitating subsequent sugarcane impurity removal.

[0034] The extended blade 42 can be directly welded or detachably mounted. This embodiment adopts a detachable mounting method, and its specific structure is as follows:

[0035] The extended blade 42 has a housing that matches the end of the smoothing blade 41. The end of the smoothing blade 41 is sleeved in the housing. Both the extended blade 42 and the smoothing blade 41 have three through holes 43, which correspond to the through holes in the smoothing blade 41. The through holes 43 are used to insert bolts, which are then used to lock the extended blade 42 and the smoothing blade 41 together using nuts.

[0036] The working principle of this utility model is as follows: the flap platform 1 flips to unload the truck loaded with sugarcane above it, causing the sugarcane to fall onto conveyor 1 2 and be transported to the pre-storage box 3. The leveler 4 below the pre-storage box 3 removes the sugarcane from the pre-storage box 3 and level it on conveyor 2 6. After being conveyed by conveyor 2 6, the sugarcane is conveyed to scatterer 1 7, where it is scattered and then transported to conveyor 3 8. If the batch of sugarcane contains a lot of dirt, conveyors 3 8, 4 9, and 5 11 are aligned in the same direction. At this point, the sugarcane is scattered twice by scatterer 2 10 and then enters the drum screen 12 for impurity removal, ultimately producing sugarcane with fewer impurities. If the sugarcane batch has less dirt, the conveying directions of the two conveyors 49 are made perpendicular to the conveying directions of conveyors 38 and 511, and the conveying directions of the two conveyors 49 are opposite, so that the sugarcane is conveyed to the drum screen 12 through conveyors 49 and 614 located in conveyor 38 and conveyors 49 and 511 located in conveyor 511.

[0037] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
