Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screen equipment, and more specifically, to a pine nut grading vibrating screen. Background Art
[0002] The pine nut grading vibrating screen is a device used to grade and screen pine nuts according to size, shape and other characteristics. It usually uses vibration to make the pine nuts move on the screen. The screen holes of different specifications can allow pine nuts of different sizes to pass through, thereby achieving grading.
[0003] The existing vibrating screening device is fixed with bolts, etc., which makes it difficult to disassemble the screen and the bolts are easily lost.
[0004] After searching, the Chinese patent with authorization announcement number CN218743127U discloses a graded vibrating screen. The device is provided with a locking part on the front side of the screening mechanism. By twisting the convex strip on the locking part, the convex strip drives the rotating rod and the rectangular bar to rotate synchronously. The two ends of the rectangular bar are gradually exposed through the side holes. When the rectangular bar rotates, the pressure plate is gradually moved closer to the rotating rod through the telescopic spring, so that the block is separated from the surface of the screen to complete the release of the screen.
[0005] However, in actual use, the existing equipment vibrates with large pine nuts carrying small pine nuts, and some residual small pine nuts will still enter the discharge port due to factors such as the entrainment of large pine nuts, affecting product quality. Utility Model Content

The convex arc is set on the first and second screens, which can provide a buffering effect when the pine nuts fall and vibrate for screening, and at the same time prevent the occurrence of small pine nuts entrained by large pine nuts, so that the screening is more sufficient;
[0016] By setting up a feeding mechanism and performing diversion processing at the bottom of the feeding funnel, the pine nuts first enter the feeding funnel and are then evenly distributed to each chamber and thus evenly dispersed above the first screen. They will not accumulate in the middle of the first screen, which solves the problem of long screening time caused by the accumulation of pine nuts in the middle when they are added.

A convex arc 7 is provided inside the first screen 5 and the second screen 6, and two through holes 8 are provided on the outside of the first screen 5 and the second screen 6.
[0028] Specifically, when used in this structure, the first sieve 5 and the second sieve 6 are placed in the box 1, and then the vibration motor 4 is turned on. The pine nuts enter from the feeding mechanism and are then screened by the first sieve 5 and the second sieve 6. Finally, the screened pine nuts are transported out through the discharging mechanism.
[0029] In a specific embodiment, as shown in the attached Figure 2 、 3 As shown in Figures 4, 5, and 6, a rotating rod 9 is rotatably connected to the inside of the through hole 8, and rollers 10 are fixedly connected to both ends of the rotating rod 9. The first screen 5 and the second screen 6 are slidingly connected to the slide 2 inside the box body 1 through the rollers 10, so as to facilitate the replacement and cleaning of the first screen 5 and the second screen 6.
[0030] Specifically, in this structure, the first screen 5 and the second screen 6 are slid out of the box body 1 via the rollers 10 to facilitate disassembly.
[0031] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, the feeding mechanism includes a feeding funnel 11 fixedly connected to the top of the box body 1, and the bottom end of the feeding funnel 11 is fixedly connected to a first feeding pipe 12, and second feeding pipes 13 are arranged on both sides of the first feeding pipe 12, and one end of the second feeding pipe 13 is fixedly connected to the feeding funnel 11, so that the pine nuts are evenly dispersed above the first screen 5 and will not accumulate in the middle of the first screen 5.
[0032] Specifically, in this structure, after the pine nuts enter the feed funnel 11 , they are transported to the top of the first screen 5 through the first feed pipe 12 and the second feed pipe 13 .
[0033] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, the discharging mechanism includes two isolation plates 14 fixedly connected to the inside of the box body 1 and away from the feeding mechanism. The two isolation plates 14 are respectively arranged at the bottom of one end of the first screen 5 and the second screen 6. One side of the bottom of the box body 1 is connected to a discharge pipe 15 corresponding to the separation space between the first screen 5 and the second screen 6 to facilitate discharging.
[0034] Specifically, in this structure, the screened pine nuts are separated by two isolation plates 14, so that the screened pine nuts are transported out from different discharge pipes 15 respectively.
[0035] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown, the support structure includes a support block 16 fixedly connected to the bottom of the box body 1, a support seat 17 is provided at the bottom end of the support block 16, a plurality of springs 18 are fixedly connected between the support block 16 and the support seat 17, a support column 19 is provided at the bottom end of the support seat 17, a receiving seat 20 is fixedly connected to the bottom end of the support column 19, and a plurality of support frames 21 are fixedly connected to the top end of the receiving seat 20 and one side of the support column 19 to fix the box body 1.
[0036] Specifically, in this structure, when the box body 1 vibrates during use of the device, the supporting structure at the bottom can operate smoothly because the supporting column and the receiving seat are fixed by the supporting frame.
[0037] In a specific embodiment, as shown in the attached Figure 1 、 2 As shown in Figure 3, a groove 22 is provided on one side of the box body 1, a drawer plate 23 is provided on one side of the box body 1, a handle 24 is provided on the top of the drawer plate 23, protrusions 25 are provided on both sides of the drawer plate 23, and the drawer plate 23 is fixedly connected to the protrusions 25. The drawer plate 23 slides in the groove 22 through the protrusions 25 to facilitate the removal of the first screen 5 and the second screen 6, and to fix the two screens.
[0038] Specifically, when using this structure, the drawer plate 23 is taken out through the handle 24 , and then the first screen 5 and the second screen 6 are placed into the box 1 , and then the drawer plate 23 is put back into the box 1 along the groove 22 through the protrusion 25 .
[0039] The working principle of the utility model is as follows: when in use, the vibration motor 4 is first started to feed pine nuts into the feeding funnel 11, and then the pine nuts enter the box body 1 through the first feeding pipe 12 and the second feeding pipe 13 and fall on the first screen 5. Then, when the pine nuts are vibrated and screened by the first screen 5 and the second screen 6, they are dispersed by impacting on the convex arc 7 to prevent adhesion and unclean screening. The screened pine nuts fall into different discharge pipes 15 due to the obstruction of the isolation plate 14;
[0040] When the screening mechanism needs to be cleaned or replaced, the drawer plate 23 is pulled out through the handle 24, and then the first screen 5 and the second screen 6 are slid out along the slide 2 through the roller 10, and then cleaned or replaced. After the replacement is completed, the first screen 5 and the second screen 6 are first placed into the box body 1 along the slide 2, and then the drawer plate 23 is placed into the box body 1 along the groove 22.
[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
