After the walnut long hole mesh device is installed, the walnuts to be screened enter the cylindrical mesh from the feed inlet. Since the rotating shaft is arranged obliquely and one end of the feed inlet is higher than one end of the discharge outlet, the walnuts can enter the final sorting area, so that the walnut screening is more thorough. When the walnuts enter the long hole along the length direction, they can also fall along the length direction of the long hole, so that the screening is reduced compared with the round hole mesh. The step of standing up and falling from the round hole for screening is saved, and the walnut screening efficiency is greatly improved.

The meshes 2 are cylindrical. Multiple rows of elongated holes 2c are spaced apart along the circumference of the meshes 2. In each row, the elongated holes 2c are spaced apart along the axial direction of the mesh 2, and the length direction of the elongated holes 2c is parallel to the axial direction of the mesh 2. Each mesh 2 forms a sorting zone. The width of the elongated holes 2c is selected according to the size of the walnuts to be sorted. In this embodiment, the width of each elongated hole 2c is the same. Of course, it can also be set so that the width of the elongated holes 2c in each sorting zone is the same, and the width of the elongated holes 2c in different sorting zones can gradually increase along the axial direction of the mesh 2.

[0027] like Figure 2 Combination Figure 4 As shown, the mesh 2 is inclined on the frame 1, with the higher side being the feed inlet 2a and the lower side being the discharge outlet 2b. An annular baffle 2d is provided at the feed inlet 2a, and the baffle 2d is flared, with its diameter gradually increasing from the feed inlet 2a to the discharge outlet 2b. A feed hopper 13 is located on the side of the frame 1 near the feed inlet 2a, extending below into the annular baffle 2d. This structure prevents walnuts from falling during feeding. A discharge hopper 7 is also provided on the side of the frame 1 near the discharge outlet 2b, and a baffle plate is installed on the discharge hopper 7 to ensure better entry of the walnuts into the recycling device.

[0028] like Figure 4 Combination Figure 5As shown, the frame 1 is provided with a rotating shaft 3, bearings are arranged at both ends of the frame 1, the rotating shaft 3 is arranged on the bearings, and the rotating shaft 3 is inclined relative to the plane. Five circular mounting rings 4 are fixed on the rotating shaft 3 along the axial direction of the rotating shaft 3, the outer sides of adjacent mounting rings 4 are fixed with the mesh 2, and in the embodiment, the mesh 2 is wound into a cylindrical shape along the outer sides of the mounting rings 4 and welded on the mounting rings 4. Eight support rods 6 are fixedly connected in the mounting rings 4, and the side of the support rods 6 close to the rotating shaft 3 is further provided with a fixing ring 5. The support rods 6 are radially welded on the rotating shaft 3 with the rotating shaft 3 as the center, and the side of the support rods 6 close to the rotating shaft 3 is further provided with a fixing ring 5, which makes the support rods 6 more convenient and more firmly mounted on the rotating shaft 3.

[0029] A vertical rod is further arranged on the frame 1, a connecting rod 9 is rotatably arranged on the vertical rod, two connecting rods 9 are rotatably connected with a ramming rod 8, the ramming rod 8 is arranged along the axial direction of the mesh 2 and closely abuts on the long hole 2c of the mesh 2, wherein, in the embodiment, four ramming rods 8 are arranged on the frame 1, and each ramming rod 8 can cover the long hole 2c in the mesh 2 thereof. A horizontal rod 10 is further arranged between the two connecting rods 9, and the horizontal rod 10 is parallel to the ramming rod 8.

[0030] As shown in the drawings, Figure 1 In combination Figure 3 As shown, a driving member for driving the rotating shaft 3 is arranged on the side of the frame 1 close to the discharge port 2b, the driving member comprises a motor 11 fixed on the frame 1, the motor 11 is fixedly connected with a driving sprocket 15, a driven sprocket 16 is arranged at one end of the rotating shaft 3 located on the discharge port 2b of the drum screen, the driving sprocket 15 and the driven sprocket 16 are drivingly connected through a chain 17, and a protective plate 18 is further arranged outside the driving sprocket and the driven sprocket, and the protective plate 18 is mounted on the frame 1.

[0031] In operation, the motor 11 works, the driving sprocket rotates, drives the driven sprocket to rotate, the rotating shaft 3 rotates with the driven sprocket, the internal walnuts come into contact with the inner wall of the mesh 2. Since the long hole 2c is arranged on the mesh 2, when the walnuts enter the long hole 2c along the length direction, they can also fall from the long hole 2c, which saves the step of aligning the position. The small walnuts pass through the long hole 2c and enter the recycling device through the discharge mesh cover 12, and the remaining large walnuts fall along the axial direction of the inner wall of the mesh 2 into the discharge hopper 7 due to the inclined arrangement of the mesh 2, thereby realizing efficient screening of walnuts. The ramming rod 8 is attached to the long hole 2c, so that the ramming rod 8 can push the walnuts blocked in the long hole 2c back into the mesh 2 for screening, avoiding the long hole 2c being blocked, and improving the efficiency of walnut screening.
