Description

Technical Field

[0001] This utility model relates to the field of cleaning and destone removal technology, and in particular to a combined cleaning and destone removal machine. Background Technology

[0002] Grain is easily mixed with impurities such as stones during the collection process, so the first step in processing grain is to remove stones.

[0003] In existing technologies, when removing small stones, sand, and small grains from grains, the grains are generally pre-treated by using a screen. To ensure the screening effect, the grains need to roll on a long screen to ensure thorough screening. However, the long screen results in a longer destoner, which requires a larger footprint and has certain limitations. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a combined cleaning and destone-removing machine to solve the problem that the long screen causes the destone-removing machine to be too long and occupy a large area.

[0005] To achieve the above objectives, this utility model provides a combined cleaning and destoner, including a destoner box. A base is fixedly connected to the bottom of the destoner box, a feed hopper is fixedly connected to the top of the destoner box, and a discharge pipe is fixedly connected to the bottom of the destoner box. At least two screens are vertically and alternately arranged inside the destoner box, and a discharge hopper is fixedly connected to the bottom of the screen. Several discharge holes adapted to the discharge hopper are opened on the inner walls of both sides of the destoner box, and the end of the discharge hopper passes through the corresponding discharge hole. An angle control structure for changing the tilt angle of the discharge hopper is installed on the destoner box.

[0006] Preferably, the angle control structure includes rotating shafts fixedly installed on both sides of the waste discharge hopper, and the rotating shafts are rotatably connected to the stone removal box. Slider blocks are fixedly connected to both sides of the waste discharge hopper. Several clearance holes adapted to the sliders are opened on the inner walls of both sides of the stone removal box, and the sliders are located in the corresponding clearance holes. A first baffle plate is fixedly connected to the side of the slider away from the waste discharge hopper, and the first baffle plate is in contact with the outer wall of the stone removal box. An adjusting component for adjusting the height of the support column is installed on the stone removal box.

[0007] Preferably, the adjusting component includes a support column fixedly installed on the side of the first baffle away from the desink, a rectangular frame is slidably fitted on the outside of the support column, and hydraulic telescopic rods are respectively provided on both sides of the rectangular frame. The hydraulic telescopic rods are fixedly connected to the desink, and the telescopic ends of the hydraulic telescopic rods are fixedly connected to the rectangular frame.

[0008] Preferably, the bottom of the inner wall of the stone removal box is inclined.

[0009] Preferably, a second baffle plate is rotatably connected to one end of the screen facing the waste discharge hole, and the second baffle plate is located above the screen. A lifting block is rotatably connected to the top of the second baffle plate, and a guide unit adapted to the lifting block is installed inside the stone removal box.

[0010] Preferably, the guiding unit includes a plurality of guide columns disposed above the screen, the guide columns passing through the lifting block, and the two ends of the guide columns being fixedly connected to the inner wall of the destone box through support parts.

[0011] The beneficial effects of this utility model are as follows: The screen is driven to rotate by the angle control structure so that the horizontal position of the end of the screen away from the discharge hole is lower than the horizontal position of the other end of the screen. The grain to be screened is added into the destone box through the discharge pipe. The screen filters and screens the grains. Small stones, sand and small grain particles fall into the discharge hopper. The grain rolls on several screens. Finally, the grain that has been screened by the screens is discharged through the discharge pipe. When it is necessary to clean the impurities in the discharge hopper, the screen is driven to rotate in the opposite direction by the angle control structure so that the horizontal position of the screen facing the discharge hole is lower than the horizontal position of the other end of the screen. Several screens are arranged vertically, which reduces the floor space of the destoner and facilitates the screening of small stones, sand and small grain particles. Attached Figure Description

[0021] This specification provides one or more embodiments of a combined cleaning and destone-removing machine, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a destoning box 1, a base 2 fixedly connected to the bottom of the destoning box 1, a feed hopper 3 fixedly connected to the top of the destoning box 1, and a discharge pipe 4 fixedly connected to the bottom of the destoning box 1. At least two screens 5 are vertically arranged alternately inside the destoning box 1. A discharge hopper 6 is fixedly connected to the bottom of each screen 5. Several discharge holes 7, adapted to the discharge hopper 6, are respectively opened on the inner walls of both sides of the destoning box 1, and the ends of the discharge hopper 6 pass through the corresponding discharge holes 7. An angle control structure is installed on the destoning box 1 to change the tilt angle of the discharge hopper 6. The angle control structure drives the screens 5 to rotate, so that the horizontal position of the end of the screen 5 away from the discharge hole 7 is lower than that of the other end of the screen 5. At the horizontal position of the end, the grain to be screened is added into the destone box 1 through the discharge pipe 4. It is filtered and screened through the screen 5. Small stones, sand and small grain particles fall into the impurity discharge hopper 6 through the screen 5. The grain rolls alternately on several screens 5. Finally, the grain screened by the screen 5 is discharged through the discharge pipe 4. When it is necessary to clean the impurities in the impurity discharge hopper 6, the screen 5 is driven to rotate in the opposite direction by the angle control structure so that the horizontal position of the end of the screen 5 facing the impurity discharge hole 7 is lower than the horizontal position of the other end of the screen 5. Several screens 5 are arranged vertically to reduce the footprint of the destoner and facilitate the screening of small stones, sand and small grain particles.

[0022] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the angle control structure includes rotating shafts 8 fixedly installed on both sides of the waste discharge hopper 6, and the rotating shafts 8 are rotatably connected to the stone removal box 1. Slider blocks 9 are fixedly connected to both sides of the waste discharge hopper 6. Several clearance holes 10 adapted to the sliders 9 are opened on the inner walls of both sides of the stone removal box 1, and the sliders 9 are located within the corresponding clearance holes 10. A first baffle plate 11 is fixedly connected to the side of the slider 9 away from the waste discharge hopper 6, and the first baffle plate 11 contacts the outer wall of the stone removal box 1. An adjusting component for adjusting the height of the support column 12 is installed on the stone removal box 1. The adjusting component includes a support column 12 fixedly installed on the side of the first baffle plate 11 away from the stone removal box 1. A rectangular frame 13 is slidably fitted on the outside of the support column 12. Hydraulic telescopic rods 14 are provided on both sides of the rectangular frame 13. The telescopic rod 14 and the destone box 1 are fixedly connected. The telescopic end of the hydraulic telescopic rod 14 is fixedly connected to the rectangular frame 13. The bottom of the inner wall of the destone box 1 is inclined. The first baffle plate 11 blocks the clearance hole 10 to prevent grain from leaking out of the destone box 1 through the clearance hole 10. The hydraulic telescopic rod 14 drives the rectangular frame 13 to move vertically, so that the support column 12 slides horizontally within the rectangular frame 13. The height of the support column 12 changes, and the support column 12 drives the first baffle plate 11 to move. The first baffle plate 11 can then drive the screen 5 to rotate around the rotating shaft 8 through the slider 9, changing the tilt angle between the screen 5 and the discharge hopper 6. The bottom of the inner wall of the destone box 1 is inclined, which makes it easier for the grain in the destone box 1 to slide into the discharge pipe 4 for easy discharge.

[0023] In embodiments of this utility model, such as Figure 2 and Figure 4 As shown, a second baffle plate 15 is rotatably connected to one end of the screen 5 facing the discharge hole 7, and the second baffle plate 15 is located above the screen 5. A lifting block 16 is rotatably connected to the top of the second baffle plate 15. A guide unit adapted to the lifting block 16 is installed inside the destone box 1. The guide unit includes several guide columns 17 set above the screen 5. The guide columns 17 pass through the lifting block 16, and the two ends of the guide columns 17 are fixedly connected to the inner wall of the destone box 1 through the support part 18. The second baffle plate 15 blocks the side of the screen 5 near the discharge hole 7 to prevent grain from being discharged through the discharge hole 7. When the tilt angle of the screen 5 changes, the screen 5 drives the second baffle plate 15 to move. The second baffle plate 15 rotates relative to the screen 5 and the lifting block 16 respectively, and the lifting block 16 slides vertically relative to the guide column 17 and the support part 18. When the angle of the screen 5 changes, the second baffle plate 15 can be adjusted accordingly to avoid interference.
