Description

Technical Field

[0001] This utility model relates to the technical field of beet pretreatment equipment, specifically to a beet vibrating roller soil screening mechanism. Background Technology

[0002] The sugar beets purchased by the sugar mill are transported by truck. After the trucks enter the factory area, they unload the beets into the beet cellars, and then the beets in the cellars are transported to the pre-processing section by a conveyor belt for pre-processing. The pretreatment stage first requires removing the soil from the sugar beets. Because the sugar beets have a lot of soil on their surface, they need to be filtered through a vibrating roller screen. The amount of soil depends on the area where the sugar beets are collected and the total amount of sugar beets. Depending on the amount of soil, the sugar beets are generally filtered one or two times. When the amount of soil is large, the sugar beets filtered from the vibrating roller screen need to be transferred several times by conveyor belt and filtered a second time through the vibrating roller screen, and the process is completed in batches. Therefore, continuous operation control cannot be formed during the second filtration, which affects the soil removal efficiency of the sugar beets. Utility Model Content To address the shortcomings of existing technologies, this utility model provides a beet vibrating roller soil screening mechanism. Through this mechanism, operators can independently control and select whether to filter the beets once or twice, based on the amount of soil in the beets. The beets that have undergone one or two filtrations are then transferred to a conveying ditch for subsequent processing steps.

[0003] To achieve the above objectives, this utility model provides the following technical solution: A beet vibrating roller screen mechanism includes a first vibrating roller screen, a second vibrating roller screen, a semi-circular guide ramp, a discharge bottom channel, a discharge port, a sealing plate, a lifting cylinder, a secondary filter channel, and a soil discharge channel. The discharge end of the first vibrating roller screen and the feed end of the second vibrating roller screen are connected through the semi-circular guide ramp. The bottom surface of the semi-circular guide ramp slopes from the end connected to the first vibrating roller screen to the end connected to the second vibrating roller screen. A discharge port is provided on the bottom surface of the semi-circular guide ramp corresponding to the end connected to the first vibrating roller screen. A sealing plate is provided below the discharge port. A discharge bottom channel is provided below the semi-circular guide ramp. A soil discharge channel is provided below the first and second vibrating roller screens. The bottom of the sealing plate is connected to the telescopic end of the lifting cylinder; after the sealing plate is raised to the maximum position, it blocks the discharge port; after the sealing plate is lowered to the lowest position, it connects with the surface of the discharge bottom channel; the discharge end of the second vibrating roller screen is vertically provided with a secondary filter channel.

[0004] Preferably, a beet conveyor belt is provided below the discharge bottom channel and the secondary filter channel; a flow channel is provided at the discharge end of the beet conveyor belt.

[0005] Preferably, the feeding end of the first vibrating roller screen is provided with an inclined feeding conveyor belt.

[0006] Preferably, the discharge port of the soil discharge channel passes through the support platform and is located below the support platform; a screw conveyor is provided inside the soil discharge channel; a soil conveyor belt is provided below the soil discharge channel; the soil conveyor belt and the beet conveyor belt convey in opposite directions.

[0007] Preferably, the first vibrating roller screen and the second vibrating roller screen are fixed above the support platform.

[0008] Preferably, the bottom surface of the discharge channel is an inclined slope structure; the discharge port of the discharge channel passes through the support platform and discharges material below the support platform.

[0009] Preferably, a guide rod is fixed to the bottom of the sealing plate; a guide plate is fixed to the side wall of the discharge bottom channel corresponding to the guide rod; a guide hole is provided on the guide plate; and the guide rod moves up and down along the guide hole.

[0010] The beneficial effects of this utility model are: After checking the soil content of the sugar beets in the truck, the operators determine whether the sugar beets need secondary filtration. If secondary filtration is required, they control the lifting cylinder to raise it and the sealing plate to block the discharge port. After the sugar beets exit from the first vibrating roller screen, they will pass through the semi-circular guide ramp and then enter the second vibrating roller screen for secondary filtration. This ensures the filtration effect and forms a continuous soil screening operation.

Detailed Implementation like Figure 1-4 As shown, a beet vibrating roller screen mechanism is disclosed. This mechanism mainly serves as a connector, facilitating operators to control whether the material is filtered once or twice. The first vibrating roller screen 1 is a primary filtration device, and the second vibrating roller screen 2 is a secondary filtration device. The first vibrating roller screen 1 and the second vibrating roller screen 2 are fixed above the support platform 16. The discharge end of the first vibrating roller screen 1 and the feed end of the second vibrating roller screen 2 are connected by a semi-circular guide ramp 3.

[0018] The working principle is as follows: Workers confirm the soil content of the sugar beets to determine if secondary filtration is needed. The sugar beets, containing soil, are conveyed to the first vibrating roller screen 1 via an inclined feeding conveyor belt 13 for initial soil screening. After initial screening, the sugar beets enter the semi-circular guide ramp 3. If secondary filtration is required, the lifting cylinder 7 raises the sealing plate 6, blocking the discharge port 5. This allows the sugar beets to enter the second vibrating roller screen 2 for secondary filtration along the semi-circular guide ramp 3. If secondary filtration is not needed, the lifting cylinder 7 lowers, allowing the sugar beets to enter the discharge bottom channel 4 from the discharge port 5. Both the sugar beets screened once and twice are conveyed to the flow channel 12 via the sugar beet conveyor belt 14.
