Description

Technical Field

[0001] This utility model relates to the field of material size sorting technology, specifically to a grid-type size sorting machine with adjustable aperture. Background Technology

[0002] In industrial production and processing scenarios such as agricultural product processing, mechanical parts screening, and chemical raw material grading, it is often necessary to accurately sort materials according to their size and specifications to meet subsequent production or usage needs.

[0003] Most of the current fence-type sorting equipment on the market requires disassembly and replacement of fence components to change the sorting specifications. This operation is cumbersome and time-consuming, which seriously affects production efficiency. Moreover, the existing equipment's pushing mechanism mostly adopts a single drive method, which is not stable enough during the pushing process, making it easy for the sorting box to be difficult for workers to pick up. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable aperture grid-type size sorting machine, thereby solving the problems of cumbersome aperture adjustment and poor material pushing stability in traditional grid-type sorting machines mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable aperture grid-type size sorting machine, comprising: a mounting frame, a feeding box fixedly connected to the upper surface of the mounting frame, a discharge port on one side of the feeding box, a horizontal plate fixedly connected inside the mounting frame, a sorting mechanism provided on the upper surface of the horizontal plate, the sorting mechanism including a mounting ring movably connected to the upper surface of the horizontal plate, a sorting shaft movably connected inside the mounting ring, a plurality of first rotating gears fixedly connected to the outer walls of a plurality of sorting shafts, a plurality of second rotating gears fixedly connected to the outer walls of the plurality of sorting shafts, and a first chain drivingly connected to the outer walls of the first rotating gears and the second rotating gears.

[0006] Preferably, a drive mechanism is also provided on one side of the mounting bracket. The drive mechanism includes a drive motor fixedly connected to one side of the mounting bracket. A rotating shaft is fixedly connected to the output end of the drive motor. A first transmission gear is fixedly connected to the outer wall of the rotating shaft. A second chain is drivenly connected to the outer walls of the first transmission gear and the second rotating gear.

[0007] Preferably, a sorting box is fixedly connected inside the mounting frame, and two pairs of baffles are fixedly connected to the upper surface of the sorting box.

[0008] Preferably, a pushing mechanism is also provided on one side of the mounting frame. The pushing mechanism includes a mounting plate fixedly connected to one side inside the mounting frame. A pair of slide rails are fixedly connected to the upper surface of the mounting plate. A fixing plate is fixedly connected to the upper surface of the mounting plate. An air pump is fixedly connected to one side of the fixing plate. An air rod is fixedly connected to the output end of one side of the air pump. A pair of guide rods are movably connected to the left and right sides inside the fixing plate. A material distribution box is fixedly connected to the output end of one side of the air rod and the guide rods. Beneficial effects

[0009] This invention provides a grid-type size sorting machine with adjustable aperture. Compared with the prior art, it has the following advantages: The sorting mechanism, with its movable connection between the mounting ring and the horizontal plate, allows for flexible adjustment of the spacing between multiple sorting shafts. It also facilitates component replacement and rapid adjustment of aperture specifications, adapting to the sorting needs of materials of different sizes. The transmission action of the first rotating gear, the second rotating gear, and the first chain enables the rotation of multiple sorting shafts. The pushing mechanism uses an air pump to extend and retract the air rod, which in turn drives the sorting box to move smoothly along the slide rail. A pair of guide rods provide guidance and limit, effectively improving the stability and accuracy of the pushing process and preventing materials inside the sorting box from being difficult for workers to collect. The drive mechanism uses a drive motor to rotate the first transmission gear via a rotating shaft, which then transmits power to the second rotating gear via the second chain. This, combined with the first chain, ensures synchronous rotation of all sorting shafts, guaranteeing consistent rotation speed and uniform material conveying rate at the gaps in the grid. This avoids sorting errors caused by excessively fast or slow local conveying, significantly improving the accuracy of size sorting. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0013] Please see Figure 1 - Figure 3 As shown, this embodiment proposes an adjustable aperture grid-type size sorting machine, including: a mounting frame 1, a feeding box 2 fixedly connected to the upper surface of the mounting frame 1, a discharge port 3 opened on one side of the feeding box 2, a horizontal plate 4 fixedly connected inside the mounting frame 1, a sorting box 14 fixedly connected inside the mounting frame 1, two pairs of baffles 15 fixedly connected to the upper surface of the sorting box 14, a sorting mechanism provided on the upper surface of the horizontal plate 4, the sorting mechanism including a mounting ring 5, a sorting shaft 6, a first rotating gear 7, a second rotating gear 8 and a first chain 9, a mounting ring 5 movably connected to the upper surface of the horizontal plate 4, a sorting shaft 6 movably connected inside the mounting ring 5, a plurality of first rotating gears 7 fixedly connected to the outer walls of a plurality of sorting shafts 6, a plurality of second rotating gears 8 fixedly connected to the outer walls of a plurality of sorting shafts 6, and a first chain 9 drivingly connected to the outer walls of the first rotating gears 7 and the second rotating gears 8; When the drive motor 10 of the drive mechanism starts, the power is transmitted through the rotating shaft 11, the first transmission gear 12, and the second chain 13 to the second rotating gear 8 on any sorting shaft 6, causing the sorting shaft 6 to rotate synchronously. When the sorting shaft 6 rotates, the first rotating gear 7 and the second rotating gear 8 rotate synchronously. Since the first rotating gears 7 on all sorting shafts 6 are mutually transmitted through the first chain 9, and the second rotating gears 8 on some sorting shafts 6 are also assisted in meshing through the first chain 9, the power is quickly transmitted to all other sorting shafts 6 through the first chain 9, so that all sorting shafts 6 rotate at the same speed and synchronously.

[0014] Preferred, such as Figure 1 As shown, a drive mechanism is also provided on one side of the mounting frame 1. The drive mechanism includes a drive motor 10, a rotating shaft 11, a first transmission gear 12, and a second chain 13. The drive motor 10 is fixedly connected to one side of the mounting frame 1. The rotating shaft 11 is fixedly connected to the output end of one side of the drive motor 10. The first transmission gear 12 is fixedly connected to the outer wall of the rotating shaft 11. The second chain 13 is connected to the outer wall of the first transmission gear 12 and the second rotating gear 8. The drive motor 10 drives the rotating shaft 11 to rotate synchronously. When the rotating shaft 11 rotates, the first transmission gear 12 rotates together with the rotating shaft 11. Since the first transmission gear 12 is connected to the second rotating gear 8 in the sorting mechanism through the second chain 13, the rotation of the first transmission gear 12 is transmitted smoothly to the second rotating gear 8 through the meshing transmission of the second chain 13.

[0015] Preferred, such as Figure 3 As shown, a pushing mechanism is also provided on one side of the mounting frame 1. The pushing mechanism includes a mounting plate 16, a slide rail 17, a fixed plate 18, an air pump 19, an air rod 20, a guide rod 21, and a dispensing box 22. The mounting plate 16 is fixedly connected to one side of the inside of the mounting frame 1. A pair of slide rails 17 are fixedly connected to the upper surface of the mounting plate 16. The fixed plate 18 is fixedly connected to the upper surface of the mounting plate 16. The air pump 19 is fixedly connected to one side of the fixed plate 18. An air rod 20 is fixedly connected to the output end of one side of the air pump 19. A pair of guide rods 21 are movably connected to the left and right sides inside the fixed plate 18. The dispensing box 22 is fixedly connected to the output end of one side of the air rod 20 and the guide rod 21. The air pump 19 drives the air rod 20 to extend and retract, and the output end of the air rod 20 drives the material distribution box 22 to move synchronously. The output end of the guide rod 21 is connected to the material distribution box 22, which plays a precise guiding and limiting role for the material distribution box 22, preventing the material distribution box 22 from shifting left or right or tilting. In addition, the slide rail 17 is slidably connected to the material distribution box 22, thereby improving the stability of the movement.

[0016] When this utility model is in use, the material to be sorted is put into the feeding box 2 fixed on the upper surface of the mounting frame 1. Under the action of its own gravity, the material falls at a constant speed into the material distribution box 22 of the pushing mechanism through the discharge port 3 opened on one side of the feeding box 2, thus completing the initial feeding and temporary storage of the material. The drive motor 10 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the first transmission gear 12 to rotate. The power is transmitted to the second rotating gear 8 of the sorting mechanism via the second chain 13. The first chain 9 drives all sorting shafts 6 to rotate synchronously in the same direction and at the same speed, forming a stable fence-type sorting channel. Under the action of its own gravity, the material falls into the sorting channel formed by the sorting shafts 6 through the discharge port 3.

[0017] When the material in the material distribution box 22 reaches the preset amount, the air pump 19 drives the air rod 20 to extend. The air rod 20 drives the material distribution box 22 to slide smoothly along the slide rail 17 of the mounting plate 16 in the same direction. The material distribution box 22 is pushed to the material collection station that is convenient for the staff to operate, so that the staff can quickly collect the material collected in the box. After the staff collects the material in the sorting box 22, the air pump 19 drives the air rod 20 to retract. Under the guidance of the guide rod 21 and the support of the slide rail 17, the sorting box 22 smoothly returns to the initial collection position, waiting for the next collection of material on the screen. When it is necessary to sort materials of different sizes and specifications, the mounting ring 5 and the horizontal plate 4 are connected by fixed bolts. The mounting ring 5 is pushed to drive the internally movable connection of several sorting shafts 6 to move as a whole, changing the spacing between the sorting shafts 6.

[0018] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
