Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.
[0023] like Figure 1 As shown, the multi-stage flexible roller-brush combined garlic-soil separation equipment of the present invention includes a housing 1, a primary selection unit 3, a cleaning unit 4, and a transmission assembly 5. The top of the housing 1 is open, serving as the inlet for the garlic-soil mixture. The rear end of the housing 1, away from the inlet, is open, serving as the garlic outlet. Two side plates are welded to the housing 1 at the outlet position, and a thin steel plate with neatly arranged perforations is welded between the side plates. The thin steel plate is inclined to facilitate the smooth discharge of garlic. Several small holes are provided at the top of the housing 1 for easy observation of the garlic-soil separation process inside the housing 1. Universal wheels 2 are installed at the four corners of the bottom of the housing 1 for easy movement. A hole is provided at the center of the bottom of the housing 1 for the discharge of separated soil. Figure 3 As shown, inside the box 1, there is a thin steel plate that is welded at an angle. This plate is used to receive the soil that is screened out from above and to allow the soil to gather towards the center under the action of gravity. The soil then slides down the steel plate and is finally discharged to the ground through the bottom hole, thus completing the soil discharge process.
[0024] like Figure 1 , 3As shown in Figure 4, the preliminary selection unit 3 includes a preliminary selection component 27, a primary cleaning unit, and a cleaning baffle 29. The preliminary selection component 27 is installed inside the housing 1 and located below the inlet. It includes a square metal plate. On one side of the square metal plate, multiple rubber-coated and inclined aluminum alloy tubes are welded in parallel to receive the garlic-soil mixture and perform preliminary screening of the soil. The other side of the square metal plate is welded and fixed to the inner wall of the housing 1. The primary cleaning unit uses a cleaning screen 28. The cleaning screen 28 is arranged at an angle. The front of the cleaning screen 28 consists of multiple parallel arc-shaped aluminum alloy tubes welded together to ensure the garlic falls flexibly. The other end of each arc-shaped aluminum alloy tube is welded to one side of a horizontal straight aluminum alloy tube. On the other side of the horizontal straight aluminum alloy tube, multiple straight aluminum alloy tubes are welded in parallel to form the lower structure of the cleaning screen 28. The aluminum alloy tubes that make up the cleaning screen 28 are all covered with rubber. The arc-shaped aluminum alloy tube end of the cleaning screen 28 is located directly below the end of the preliminary selection component 27 to facilitate the reception of garlic falling from the end of the preliminary selection component 27.
[0025] like Figure 1 , 2 As shown, both sides of the box body 1 have waist-shaped slots. One end of the horizontal straight aluminum alloy tube of the cleaning screen 28 passes through the waist-shaped slot and is connected to the cleaning pulley. The cleaning pulley is installed on the pulley guide rail fixed on the side of the box body 1 and can slide freely along the pulley guide rail. The other end of the horizontal straight aluminum alloy tube of the cleaning screen 28 passes through the waist-shaped slot and is connected to the rod end joint bearing 25 through the connecting rod 26.
[0026] like Figure 3 As shown, one end of the cleaning baffle 29 is inclinedly arranged on the top wall of the housing 1 via a torque hinge, and the other end is close to the end of the cleaning screen 28. The torque hinge is a conventional component consisting of two steel hinges fitted together by a spring with a fixed torque. Under normal working conditions, the torque hinge is in the closed state, at which time the cleaning baffle 29 is close to the cleaning screen 28 to guide the flow of the garlic-soil mixture after initial selection and prevent backflow. When the flow rate of the mixture is too large, the torque hinge opens, increasing the distance between the cleaning baffle 29 and the cleaning screen 28 to prevent clogging. The material of the cleaning baffle 29 is a thin steel plate with a rubber coating on the surface.
[0027] like Figure 3 As shown, the secondary cleaning unit 4 is installed inside the housing 1 and located behind the primary cleaning unit 3. It includes several rows of equally spaced soil-cleaning rollers 11, which are arranged along the garlic conveying direction. Both ends of the soil-cleaning rollers 11 are fixed to the housing 1 by bearings. Above the soil-cleaning rollers 11, there are several rows of equally spaced brush shafts 16, which are arranged along the garlic conveying direction. Both ends of the brush shafts 16 are also fixed to the housing 1 by bearings. The brush shafts 16 are specifically located between two adjacent soil-cleaning rollers 11. Several soil-cleaning brushes 10 are installed on the brush shafts 16 for brushing off the soil from the garlic.
[0028] likeFigure 1 , 2 As shown in Figures 3 and 5, a first driving synchronous pulley 12 is fixedly installed on the portion of the shaft of a cleaning roller 11 near the outlet, extending beyond the bearings at both ends. A first driven synchronous pulley is fixedly installed on the portion of the shaft of the remaining cleaning rollers 11 extending beyond the bearings at both ends. The first driving synchronous pulley 12 and the first driven synchronous pulley are connected by a first synchronous belt. A second driving synchronous pulley 8 is fixedly installed on the portion of the brush shaft 16 near the outlet, extending beyond the bearings at both ends. A second driven synchronous pulley 18 is fixedly installed on the portion of the remaining brush shafts 16 extending beyond the bearings at both ends. The second driving synchronous pulley 8 and the second driven synchronous pulley 18 are connected by a second synchronous belt 19.
[0029] like Figure 1 , 2 As shown in Figures 3 and 5, the transmission assembly includes a first motor 5, a second motor 13, and a third motor 20, all mounted on the top shell of the housing 1 and secured with bolts. It also includes a first driven sprocket 9 fixedly mounted on the shaft of the cleaning roller 11 outside the first driving synchronous pulley 12, and a second driven sprocket 17 fixedly mounted on the brush shaft 16 outside the second driving synchronous pulley 8. The output end of the first motor 5 is fixedly mounted with the first driving sprocket 6, which is connected to the first driven sprocket 9 via a first transmission chain 7. The first motor 5 provides power for the rotation of the cleaning roller 11, facilitating the transport of garlic. The output end of the second motor 13 is fixedly mounted with the second driving sprocket 14, which is connected to the second driven sprocket 17 via a second transmission chain 15. The second motor 13 provides power for the rotation of the brush shaft 16, facilitating the cleaning of soil from the garlic.
[0030] like Figure 1 , 2 As shown in Figures 3 and 5, a third drive sprocket 21 is fixedly installed at the output end of the third motor 20. A transmission shaft 23 is installed on the side wall of the housing 1 near the third motor 20 via a bearing. A third driven sprocket 24 is fixedly installed at one end of the transmission shaft 23 extending outside the housing 1. The third driven sprocket 24 and the third drive sprocket 21 are connected by a third transmission chain 22. A rod end spherical bearing 25 is also fixedly installed on the transmission shaft 23 of the third driven sprocket 24. The other end of the rod end spherical bearing 25 is connected to the cleaning screen 28. The third motor 20 can drive the third driven sprocket 24 and the transmission shaft 23 to rotate, thereby driving the cleaning screen 28 to reciprocate back and forth for preliminary screening and separation of garlic soil.
[0031] The working principle of the multi-stage flexible shaft roller-brush combined garlic fruit and soil separation equipment of the present invention is as follows:
[0032] The garlic-soil mixture is poured into the inlet of the housing 1, falls onto the cleaning screen 28 via the preliminary selection component 27, and the power output from the third motor 20 is transmitted to the rod end joint bearing 25 through the third transmission chain 22, and then to the cleaning screen 28 through the connecting rod 26, driving the cleaning screen 28 to reciprocate, while initially removing the soil from the garlic and conveying the initially screened garlic-soil mixture to the soil-cleaning roller 11; the power of the first motor 5 is transmitted to the soil-cleaning roller 11 near the outlet through the first transmission chain 7, and then transmitted by the first synchronous belt. The mixture is then passed to the remaining cleaning rollers 11, which rotate to convey the garlic-soil mixture. During the conveying process, the power of the second motor 13 is transmitted to the brush shaft 16 near the outlet via the second transmission chain 15, and then to the remaining brush shafts 16 via the second synchronous belt 19. The brush shafts 16 drive the cleaning brushes 10 to rotate, and the garlic-soil mixture continuously collides with the cleaning rollers 11 and rubs against the cleaning brushes 10, further separating the garlic from the soil. The separated soil is discharged from the bottom hole of the box 1, and the separated garlic is sent out from the rear outlet of the box 1.
