DETAILED DESCRIPTION

[0026] The embodiment of the present invention provides a marketing product selection and grading device, such as Figure 1-6 As shown, it includes a main body 11, a grading cavity 12, a first discharge port 13, an inlet port 14, a second discharge port 15, a first grading basket 16, a second grading basket 17, a first slot 18, a second slot 19, a first slider 20, a second slider 21, a first opening 22, a grading rod 23, a third slot 24, an external thread 25, an adjustment block 26, a second opening 27, a third slider 28, a limit nut 30, a third opening 31, an internal thread 32, a drive motor 33, an elastic member 34, and a reset slider 35.

[0027] like Figure 1-6 As shown, a grading cavity 12 is provided in the main body 11, a first discharge port 13 is provided on one end surface of the main body 11, an inlet port 14 and a second discharge port 15 are provided on the other end surface of the main body 11, a first grading basket 16 and a second grading basket 17 are placed in the grading cavity 12, first slots 18 are provided on both side surfaces of the main body 11, a plurality of screening units are slidably connected in the first slots 18, the screening units include a grading rod 23, two sliding assemblies and a periodic adjustment assembly, the periodic adjustment assembly includes adjustment blocks 26 of several specifications, the adjustment block 26 is detachably connected to one end of the grading rod 23, the sliding assembly is sleeved on both ends of the grading rod 23, the sliding assembly is slidably connected to the first slot 18, and the ratio of the long chord to the short chord of the adjustment block 26 is four to three.

[0028] One end of the grading rod 23 is connected to a driving motor 33, and the other end of the grading rod 23 is provided with a third slot 24 and an external thread 25 on the outer circumferential surface, a second opening 27 is provided on the adjusting block 26, a third slider 28 is provided in the second opening 27, the third slider 28 is fixedly connected to the adjusting block 26, the third slider 28 is slidably connected to the third slot 24, the external thread 25 is threadedly connected to the limiting nut 30, a third opening 31 is provided in the limiting nut 30, an internal thread 32 is provided on the outer circumferential surface of the third opening 31, and the internal thread 32 is adapted to the external thread 25.

[0029] The sliding assembly includes a first slider 20 and a second slider 21. The second slider 21 is fixedly connected to the first slider 20. A first opening 22 is provided in the first slider 20. The first opening 22 is slidably connected to the grading rod 23. A second slot 19 is also provided in the first slot 18. The first slider 20 is slidably connected to the first slot 18, and the second slider 21 is slidably connected to the second slot 19.

[0030] An elastic member 34 is fixedly connected to one end wall of the first slot 18, a reset slider 35 is fixedly connected to the other end of the elastic member 34, the reset slider 35 is slidably connected to the first slot 18, the output shaft of the drive motor 33 is fixedly connected to the grading rod 23, the base of the drive motor 33 is fixedly connected to the first slider 20, and the third slider 28 is adapted to the third slot 24.

[0031] When the adjusting block 26 rotates until the long chord of the adjusting block 26 is located on the horizontal plane, the long chord of the adjusting block 26 is parallel to the first slot 18. At this time, the distance between the grading rods 23 is the longest limit distance. The first slider 20 pushes the reset slider 35. The reset slider 35 compresses the elastic member 34 to increase the elastic potential energy of the elastic member 34.

[0032] When the adjusting block 26 is rotated until the short chord of the adjusting block 26 is located on the horizontal plane, the short chord of the adjusting block 26 is parallel to the first slot 18. At this time, the distance between the grading rods 23 is the shortest limit distance, and at this time, the elastic member 34 provides elastic force to the reset slider 35, and the reset slider 35 pushes the first slider 20 to reset the first slider 20.

[0033] The limit distance between the grading rods 23 can be adjusted by replacing the adjustment blocks 26 of different specifications, thereby changing the specifications of the commodities that can be screened. It is worth noting that the commodities that can be graded in this solution are usually spherical or quasi-spherical.

[0034] When the present scheme is used for commodity selection and grading, first, the commodities are placed on the grading rods 23 through the feed port 14, and then the drive motor 33 is started. When the drive motor 33 drives the grading rods 23 to rotate with themselves as the axis, the grading rods 23 drive the adjustment block 26 to rotate through the third slot 24 and the third slider 28, so that the long chord and the short chord of the adjustment block 26 alternate on the horizontal plane, thereby continuously adjusting the distance between the grading rods 23.

[0035] Then, the grading rods 23 convey the commodities along the horizontal direction of the first slots 18 toward an end surface away from the feed port 14 , and commodities with specifications less than or equal to the maximum limit distance between the grading rods 23 are transported from between the grading rods 23 , such as the first grading basket 16 , the second grading basket 17 or the grading chamber 12 .

[0036] Finally, the graded commodities are taken out from the first grading basket 16 , the second grading basket 17 and the grading chamber 12 .

[0037] like Figure 3 As shown, the device can be slidably provided with eight grading rods 23 in the first slot 18, wherein the four grading rods 23 on the left are connected with smaller adjustment blocks 26, and the four grading rods 23 on the right are connected with larger adjustment blocks 26, and the short chord of the larger adjustment block 26 is equal to the long chord of the smaller adjustment block 26.

[0038] At this time, smaller commodities (i.e. commodities with a diameter less than or equal to the long chord length of the smaller-sized adjusting block 26) fall into the first grading basket 16, medium-sized commodities (i.e. commodities with a diameter greater than the long chord length of the smaller-sized adjusting block 26 and less than the long chord length of the larger-sized adjusting block 26) fall into the second grading basket 17, and large commodities (i.e. commodities with a diameter greater than the long chord length of the larger-sized adjusting block 26) fall into 12.

[0039] It is worth noting that more graded screening can be performed by arranging a larger-sized regulating block 26 after a larger-sized regulating block 26 .

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
