Technical Field

[0001] The utility model relates to the technical field of grading and screening devices, in particular to a nut grading and screening device. Background Art

[0002] During the processing of nuts, they need to be classified and screened according to their size, so that nuts of different sizes can be screened out, which makes it convenient to carry out auxiliary screening according to the size of the nuts, and then classify, process and sell them.

[0003] In actual work, the structure and function of the nut grading and screening device in the prior art are relatively complete and can basically meet the needs of daily use, but there are still the following problems:

[0004] In actual use, the nuts will be uniformly poured into the screening cylinder with different hole sizes, and then circulated according to the internal spiral feeding structure. However, since the nuts stay in the screening position of the holes of different sizes for a short time, when there are more nuts, the actual separation effect is reduced, so that smaller nuts can be screened out from the larger holes, resulting in a mixture of sizes, which is very inconvenient.

[0005] Therefore, the utility model provides a nut grading and screening device. Utility Model Content

By setting up an auxiliary screening structure 6, the auxiliary connecting rod 66 can be driven to move under the action of the first screw 64 and the first screw hole block 65, and then the motor frame 67 can be driven to move, so that the motor frame 67 can move on the inner wall of the screening drum 2, and the length of the rotating rod 611 is the effective length of different holes inside the screening drum 2, so that the first circular baffle 68 can cooperate with the second circular baffle 612 to assist in limiting the nuts, and then the nuts can be screened. By setting up an anti-sputtering structure 7, the connecting rod 75 can be driven to move under the action of the second screw 73 and the second screw hole block 74, so that the cover plate 76 can block the feed frame 5 to prevent nuts from splashing out. Under the action of the connecting auxiliary rod 78 and the blocking block 79, the inner wall of the feed frame 5 can be blocked to prevent nuts from splashing into the inside of the feed frame 5.

[0026] A step further, such as Figure 2-Figure 3As shown: the top of the outer surface of the first screw hole block 65 is fixedly connected to an auxiliary connecting rod 66, one end of the auxiliary connecting rod 66 is fixedly connected to a motor frame 67, the outer surface of the motor frame 67 is provided with a heat dissipation hole 610, a second motor 69 is fixedly installed on the inner wall of one side of the motor frame 67, one side of the outer surface of the motor frame 67 is fixedly connected to a first circular baffle 68, the output end of the second motor 69 is fixedly connected to a rotating rod 611, the outer surface of the rotating rod 611 is fixedly connected to a rectangular sweeping plate 613, the other end of the rotating rod 611 is fixedly connected to a second circular baffle 612, the U-shaped chassis 1 An auxiliary groove 62 connected to the interior of the screening drum 2 is opened on one side, and the motor frame 67, the first circular baffle 68, the second circular baffle 612, the rotating rod 611 and the rectangular sweeping plate 613 are inserted into the inner wall of the auxiliary groove 62.
