A grade screening device and system for the initial processing of navel oranges

Abstract

This invention discloses a grading device and system for the initial processing of navel oranges, comprising a washing tank and a screening tank. An ultrasonic generator is installed inside the washing tank, and a mounting rod is located on the side away from the screening tank. A guide rod with a guide groove is located at the upper end of the mounting rod. In this invention, during the operation of the screening device, all rotating rollers rotate synchronously. Since one end of the rotating roller is higher than the other, the navel oranges move from high to low along the rollers under gravity, rotating with them. Centrifugal force removes water droplets adhering to the surface. Simultaneously, the distance between adjacent rotating rollers gradually increases along the direction of orange movement, causing smaller oranges to fall into the screening tank before larger ones. Therefore, this device can both sort and dry the navel oranges.

[0010] Preferably, the lower inner surface of the screening groove is an inclined surface, and a sponge pad is provided on the inclined surface. The side of the screening groove is provided with an adjustment component for adjusting the distance between adjacent baffles.

[0011] Preferably, the adjusting assembly includes a through groove arranged along the axial direction of the rotating roller. A plurality of slide seats, which are fixedly connected to a plurality of baffles, are slidably connected to the inner side of the through groove. A drive rod is rotatably connected to the slide seat, and the slide seat is located at the center of the drive rod. The ends of two adjacent drive rods are rotatably connected. A telescopic member is fixedly connected to the side of the screening tank. The telescopic end of the telescopic member is rotatably connected to the end of one of the drive rods. A slide rod penetrating the baffle is provided inside the screening tank.

[0012] Preferably, the side of the first push block near the end of the movable bolt is an inclined surface, and the side of the second push block near the baffle is an inclined surface.

[0013] Preferably, the rotating rollers and the first push block are alternately arranged, and the distance between the larger inner diameter ends of two adjacent rotating rollers is greater than the width of the movable bolt.

[0014] Preferably, a support is provided on one side of the screening tank, a slide rail is provided on the top of the support, a placement platform is slidably connected to the top of the slide rail, the top of the placement platform has a groove, and a second box is provided in the groove, and a drive assembly is provided between the rotating roller and the placement platform.

[0015] Preferably, the driving assembly includes a driving component, which is a dual-head motor. The two output ends of the driving component are respectively provided with a first transmission component and a third transmission component. The first transmission component is connected to a plurality of rotating rollers through a second transmission component. The first transmission component, the second transmission component, and the third transmission component are all belt-pulley structures. The end face of the pulley of the third transmission component is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to the placement platform.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. The screening device of this application sets up a screening trough, sets up a frame on the screening trough, and sets up a rotating roller inside the frame. The rotating roller has a large and small head structure. When the screening device is running, all the rotating rollers rotate synchronously. Since one end of the rotating roller is higher and the other end is lower, under the action of gravity, the navel oranges will move from high to low along the rotating roller and rotate with the rotating roller. Under the action of centrifugal force, the water droplets attached to the surface can be thrown off. At the same time, the distance between adjacent rotating rollers gradually increases along the direction of movement of the navel oranges. Therefore, smaller navel oranges will fall into the screening trough before larger navel oranges. Thus, this device can sort navel oranges and also dry them by throwing off water.

[0018] 2. This application involves setting up a cleaning tank with multiple nozzles and an ultrasonic generator inside. The water sprayed from the nozzles propels the navel oranges, while the ultrasonic generator cleans the surface of the oranges through vibration. A guide rod with a guide groove is set on one side of the cleaning tank, and a sliding sleeve that mates with the guide groove is set on the outside of the guide rod. A first box is set on the sliding sleeve, and the navel oranges are placed inside the first box. When the device is running, the first box is manually pushed along the guide rod. Under the action of the guide groove, the first box rotates around the guide rod, causing the navel oranges to fall into the water in the cleaning tank for further cleaning.

[0019] 3. This application sets a drive roller and a transmission belt between the washing tank and the screening tank, and sets a movable bolt on the transmission belt. The lower end of the transmission belt is located in the washing tank. By rotating the drive roller, the movable bolt is driven to move along the transmission belt, which can transfer navel oranges from the washing tank to the screening tank for sorting. Therefore, this device does not require manual transfer, which can improve the overall efficiency of the initial processing of navel oranges and reduce the labor intensity of workers.

[0020] 4. By setting up a driving component, a first transmission component, a second transmission component, and a third transmission component, this application can realize synchronous drive control of the rotating roller and the placement platform, thereby improving drive efficiency. Furthermore, by connecting the third transmission component with a connecting rod, the placement platform can reciprocate in the plane, causing the second box to shake and allowing the stacked navel oranges to be spread out, thus achieving automated screening and collection.

[0021] 5. In this application, multiple baffles are set in the screening slot. The baffles are adjusted at equal intervals through a driving structure. The driving structure is equipped with a telescopic component, a driving rod, and a sliding block. By extending and retracting the telescopic component, the driving rod rotates, thereby moving the sliding block, which in turn moves the baffles. Adjusting the spacing between adjacent baffles can adjust the size range of the sorted navel oranges. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-6 The present invention provides a technical solution:

[0032] A grade screening device for the initial processing of navel oranges includes a washing tank 1 and a screening tank 16. An ultrasonic generator is installed inside the washing tank 1, and an installation rod 2 is installed on the side away from the screening tank 16. A guide rod 3 is installed at the upper end of the installation rod 2. The guide rod 3 has a guide groove 4, and a sliding sleeve 5 is installed on the outer side of the guide rod 3. A guide block 6 that cooperates with the guide groove 4 is installed on the inner side of the sliding sleeve 5. A clamping rod 7 is installed on the sliding sleeve 5, and a first housing 8 is installed on the inner side of the clamping rod 7. A transfer assembly is installed between the washing tank 1 and the screening tank 16. Multiple baffles 23 are installed inside the screening tank 16. A rectangular frame 18 is installed at the top of the screening tank 16. Multiple equally spaced rotating rollers 19 are installed on the inner side of the rectangular frame 18. The inner diameter of the rotating roller 19 at one end closer to the washing tank 1 is larger than the inner diameter at the other end. The navel oranges can rotate and roll along the rotating roller 19 and pass through the adjacent rotating rollers 19 and fall between different baffles 23, thereby achieving screening of different sizes.

[0033] The transfer assembly includes two drive rollers 11, with a transmission belt 12 positioned between them. The transmission belt 12 rolls in contact with both drive rollers 11, and multiple through-type movable bolts 13 are provided on the transmission belt 12. A baffle 14 is provided at one end of each movable bolt 13. A fixing rod 15 is provided at the top of the washing tank 1, and the fixing rod 15 is rotatably connected to the drive rollers 11. A second push block 21 and a first push block 20, respectively cooperating with the movable bolts 13, are provided on the inner side of the washing tank 1 and the top of the screening tank 16. The side of the first push block 20 near the end of the movable bolt 13 is inclined, and the side of the second push block 21 near the baffle 14 is also inclined. After contacting the first push block 20, the movable bolt 13 retracts inward towards the transmission belt 12. After passing the second push block 21, it extends outward from the transmission belt 12, allowing the navel oranges to fall stably between adjacent rotating rollers 19, while ensuring that they are not obstructed by the screening tank 16 during movement. The rotating rollers 19 and the first push block 20 are alternately arranged, and the distance between the larger inner diameter ends of two adjacent rotating rollers 19 is greater than the width of the movable bolt 13. This ensures that the movable bolt 13 can pass through the adjacent rotating rollers 19.

[0034] A grading system for the initial processing of navel oranges includes a grading device, a sugar content detection device, a moisture content detection device, and a packaging device, as described in any one of claims 1 to 9.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, both the guide groove 4 and the guide block 6 are arc-shaped structures. The sliding sleeve 5 has a notch, which allows the sliding sleeve 5 to pass through the mounting rod 2. The guide groove 4 consists of a straight groove and a curved groove, with the curved groove located above the washing tank 1. The curved groove causes the sliding sleeve 5 to rotate 90°, allowing the navel oranges in the first box 8 to fall into the washing tank 1.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, a support rod 9 is provided at the top of the washing tank 1, and multiple nozzles 10 distributed at equal intervals are rotatably connected to the bottom of the support rod 9. The water outlet end of the nozzle 10 is inclined towards the transfer assembly. The water spraying from the nozzles 10 can push the navel oranges floating on the water surface towards the transfer assembly.

[0037] Specifically, such as Figure 4 and Figure 5 As shown, the lower inner surface of the screening tank 16 is inclined, and a sponge pad 17 is provided on the inclined surface. An adjustment component for adjusting the distance between adjacent baffles 23 is provided on the side of the screening tank 16. The adjustment component includes a through groove 24, which is arranged along the axial direction of the rotating roller 19. Multiple slide seats 25, which are fixedly connected to multiple baffles 23, are slidably connected to the inside of the through groove 24. A drive rod 26 is rotatably connected to the slide seat 25, and the slide seat 25 is located at the center of the drive rod 26. The ends of two adjacent drive rods 26 are rotatably connected. A telescopic member 27 is fixedly connected to the side of the screening tank 16. The telescopic end of the telescopic member 27 is rotatably connected to the end of one drive rod 26. A slide rod 22 that penetrates the baffle 23 is provided inside the screening tank 16. The telescopic component 27, through its telescopic adjustment, causes the drive rod 26 to rotate, further moving the slide 25 along the through groove 24. The rotation of one drive rod 26 drags the adjacent drive rod 26, thus allowing all slides 25 to move synchronously while maintaining the same spacing between adjacent slides 25. The spacing between adjacent baffles 23 can be changed by adjusting the assembly, thereby adjusting the size range of the screened navel oranges.

[0038] Specifically, such as Figure 6 As shown, a support 28 is provided on one side of the screening tank 16, and a slide rail 29 is provided on the top of the support 28. A placement platform 30 is slidably connected to the top of the slide rail 29. The top of the placement platform 30 has a groove, and a second housing 31 is provided in the groove. A drive assembly is provided between the rotating roller 19 and the placement platform 30. The drive assembly includes a drive component 32, which is a dual-head motor. The two output ends of the drive component 32 are respectively provided with a first transmission component 33 and a third transmission component 35. The first transmission component 33 is connected to multiple rotating rollers 19 through a second transmission component 34. The first transmission component 33, the second transmission component 34, and the third transmission component 35 are all belt-pulley structures. The end face of the pulley of the third transmission component 35 is rotatably connected to a connecting rod 36, and the other end of the connecting rod 36 is rotatably connected to the placement platform 30. The drive unit 32 uses a servo motor. The drive unit 32 makes all the rotating rollers 19 rotate synchronously and in the same direction through the first transmission unit 33 and the second transmission unit 34. It also drives the placement platform 30 to reciprocate along the slide rail 29 through the third transmission unit 35 and the connecting rod 36, so that the navel oranges can fall evenly into the second box 31 and avoid the navel oranges from piling up on one side of the second box 31.

[0039] In summary, this embodiment provides a grading device and system for the initial processing of navel oranges. The navel oranges sequentially pass through a grading device, a sugar content detection device, a moisture content detection device, and a packaging device. When passing through the grading device, workers stack the navel oranges in the first box 8 and then push the first box 8 along the guide rod 3. When it reaches the middle section of the guide rod 3, the first box 8 rotates 90° with the cooperation of the guide groove 4 and the guide block 6. The navel oranges in the first box 8 fall into the water in the washing tank 1, where ultrasonic waves are generated. The device washes the surface of the navel oranges with water, while water is sprayed from the nozzle 10. The water pushes the navel oranges to move towards the transfer assembly. The drive roller 11 rotates under the drive of the drive device, and the movable bolt 13 moves from bottom to top to lift the navel oranges. Then the navel oranges are placed between adjacent rotating rollers 19. The rotating rollers 19 rotate under the drive of the drive member 32, the first transmission member 33 and the second transmission member 34. The navel oranges roll along the rotating rollers 19 while rotating, and then fall from between the adjacent rotating rollers 19 and fall into the second box 31 along the sponge pad 17.
