The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0039] like Figures 1 to 3As shown, a feeding device 10 of an embodiment includes a feeding mechanism 100, a discharging mechanism 200 and an adjusting mechanism 300. The adjusting mechanism 300 includes an adjusting sleeve 310, a fixed stopper 320 and a movable stopper 330. The adjusting sleeve 310 is respectively rotatably sleeved on the output end of the feeding mechanism 100 and the input end of the discharging mechanism 200, so that the feeding mechanism 100 can be connected with the discharging mechanism 200 through the adjusting sleeve 310, and the adjusting sleeve 310 can rotate relative to the feeding mechanism 100 and the discharging mechanism 200. The fixed stopper 320 is located in the adjusting sleeve 310 and is fixedly connected to the feeding mechanism 100 or the discharging mechanism 200. The movable stopper 330 is located in the adjusting sleeve 310 and is fixedly connected to the adjusting sleeve 310, so that the movable stopper 330 rotates synchronously with the adjusting sleeve 310, and the movable stopper 330 can be driven to rotate by rotating the adjusting sleeve 310. An adjustable opening 301 is formed between the moving stopper 330 and the fixed stopper 320. The adjustable opening 301 is used to pass the material. The material of the feeding mechanism 100 enters the discharging mechanism 200 through the adjustable opening 301. The discharging mechanism 200 uses the material to transport the material to the vibrating screen 20. The size of the adjustable opening 301 changes when the adjusting sleeve 310 rotates. The size of the adjustable opening 301 is adjusted by rotating the adjusting sleeve 310. The adjusting sleeve 310 is fixed relative to the feeding mechanism 100 and the discharging mechanism 200 respectively during material discharge, that is, the adjusting sleeve 310 is fixed during material discharge to prevent the adjusting sleeve 310 from rotating during material discharge.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, before unloading, the adjusting sleeve 310 is rotated so that the adjusting sleeve 310 drives the moving stopper 330 to rotate, so as to adjust the size of the adjustable opening 301 between the moving stopper 330 and the fixed stopper 320 to an appropriate value, and then the adjusting sleeve 310 is fixed, and then the material is poured into the feeding mechanism 100, and the vibration motor 110 of the feeding mechanism 100 vibrates to promote the flow of the material, so that the material passes through the adjusting sleeve 310 and the discharging mechanism 200 in turn from the feeding mechanism 100, and finally enters the vibrating screen 20 from the discharging mechanism 200, wherein the material passes through the adjustable opening 301 inside the adjusting sleeve 310; after pushing the material for a certain period of time, the pushing of the material is stopped to stop unloading, and thus one unloading is completed.

[0041] The above-mentioned feeding device 10 rotates the adjusting sleeve 310 so that the adjusting sleeve 310 drives the moving stopper 330 to rotate, so as to adjust the size of the adjustable opening 301 between the moving stopper 330 and the fixed stopper 320. Since the material passes through the adjustable opening 301 during feeding, the material flow rate can be adjusted by adjusting the size of the adjustable opening 301, so that the feeding amount per unit time can be adjusted; since the adjusting sleeve 310 is fixed during feeding, the adjusting sleeve 310 will not rotate after the feeding device 10 is used for a long time, so that the stability of the adjusting sleeve 310 and the moving stopper 330 is relatively high, the dimensional stability of the adjustable opening 301 is improved, and the feeding stability of the feeding device 10 is improved.

[0042] like Figure 3 As shown, in some embodiments, the stopper 320 is fixedly connected to the output end of the discharging mechanism 200. Of course, in other embodiments, the stopper 320 can also be fixedly connected to the input end of the feeding mechanism 100.

[0043] like Figure 3 As shown, in some embodiments, the fixed stopper 320 and the movable stopper 330 are both in the shape of a plate.

[0044] like Figure 3 As shown, in some embodiments, the stopper 320 is located at the upper half of the feeding mechanism 100 or the discharging mechanism 200 to prevent the stopper 320 from blocking the deposited material. In this embodiment, since the stopper 320 does not block the deposited material, when there is less material in the feeding mechanism 100, the material can also pass through the adjustable opening 301, reducing the waste of material.

[0045] like Figure 3 As shown, in some embodiments, the fixed stopper 320 is fixedly connected to the output end of the discharging mechanism 200, and the side of the fixed stopper 320 facing away from the discharging mechanism 200 contacts the side of the moving stopper 330 adjacent to the discharging mechanism 200. In this embodiment, when the material impacts the moving stopper 330, since the side of the fixed stopper 320 facing away from the discharging mechanism 200 contacts the side of the moving stopper 330 adjacent to the discharging mechanism 200, the fixed stopper 320 can provide support force to the moving stopper 330, thereby suppressing the deformation of the fixed stopper 320, improving the stability of the adjustable opening 301, and extending the service life of the moving stopper 330.

[0046] like Figure 3 As shown, in some embodiments, the stopper 320 and / or the moving stopper 330 are semicircular. Of course, the shapes of the stopper 320 and the moving stopper 330 are not limited to semicircular. For example, in other embodiments, the stopper 320 is triangular, circular or other shapes, and the stopper 320 is triangular, square or other shapes.

[0047] like Figure 1 As shown, in some embodiments, the adjustment mechanism 300 further includes a rotation drive assembly 340, which is installed outside the adjustment sleeve 310, and the power output end of the rotation drive assembly 340 is connected to the adjustment sleeve 310. In this embodiment, the rotation drive assembly 340 is used to drive the adjustment sleeve 310 to rotate, thereby realizing the automatic rotation of the adjustment sleeve 310, improving the convenience of rotating the adjustment sleeve 310, improving the convenience of adjusting the adjustable opening 301, and improving the convenience of adjusting the feeding amount.

[0048] like Figure 1 As shown, further, the rotary drive assembly 340 is installed on the feeding mechanism 100 or the discharging mechanism 200. Of course, the rotary drive assembly 340 can also be installed on other structures outside the adjustment sleeve 310.

[0049] like Figure 1 As shown, in some embodiments, the rotary drive assembly 340 includes a driving motor 341, a lever 342 and a rotating plate 343. The driving motor 341 is installed on the feeding mechanism 100 or the discharging mechanism 200. The first end of the lever 342 is fixedly connected to the output shaft of the driving motor 341. The rotating plate 343 is fixedly sleeved on the adjusting sleeve 310. A slot 3431 is provided at the periphery of the rotating plate 343. The second end of the lever 342 is clamped in the slot 3431. In this embodiment, the driving motor 341 drives the lever 342 to swing, the lever 342 drives the rotating plate 343 to rotate, and the rotating plate 343 drives the adjusting sleeve 310 to rotate, thereby realizing the automatic rotation of the adjusting sleeve 310.

[0050] like Figure 1 As shown, further, there are multiple slots 3431, and the multiple slots 3431 are arranged at intervals along the circumference of the rotating plate 343. In this embodiment, when the second end of the lever 342 is engaged in different slots 3431, the adjustable opening 301 has different openings, which increases the adjustment range of the adjustable opening 301.

[0051] Of course, in other embodiments, the blanking device 10 can omit the rotary drive assembly 340 and adjust the adjustment sleeve 310 manually.

[0052] like Figure 2As shown, in some embodiments, the discharging mechanism 200 includes a discharging pipe assembly 210, a screening assembly 220, a storage box 230 and a vibrator 240. The adjusting sleeve 310 is rotatably sleeved on the input end of the discharging pipe assembly 210, a screening port 2101 is provided on the lower side of the discharging pipe assembly 210, and the screening assembly 220 is located at the screening port 2101 and connected to the discharging pipe assembly 210. The storage box 230 is connected to the lower side of the discharging pipe assembly 210, a storage cavity 231 is formed inside the storage box 230, and the storage cavity 231 is located on the lower side of the screening assembly 220, and a discharging port 232 is provided in the storage box 230, and the discharging port 232 is connected to the storage cavity 231, and the discharging port 232 is used to be connected to the feeding end of the vibrating screen 20. The vibrator 240 is connected to the discharge pipe assembly 210, the screening assembly 220 or the storage box 230, so that the vibration of the vibrator 240 can be transmitted to the screening assembly 220, thereby causing the screening assembly 220 to vibrate and crush the material. In this embodiment, the material enters the discharge pipe assembly 210 through the adjustable opening 301. In the process of the material passing through the discharge pipe assembly 210, the vibrator 240 drives the screening assembly 220 to vibrate, so that the screening assembly 220 crushes the agglomerated material. After the material is crushed, it passes through the screening assembly 220 and falls into the storage chamber 231, and then flows from the discharge port 232 to the feed end of the vibrating screen 20. Since the material is crushed by the screening assembly 220 before entering the vibrating screen 20, the agglomerated material is prevented from damaging the screen of the vibrating screen 20, thereby extending the service life of the screen of the vibrating screen 20.

[0053] like Figure 2 As shown, further, the vibrator 240 is installed on the outside of the storage box 230 to maintain the vibrator 240. In this embodiment, the vibration force of the vibrator 240 is transmitted to the screening assembly 220 through the storage box 230, so that the screening assembly 220 can vibrate.

[0054] like Figure 4 As shown, in some embodiments, the screening assembly 220 includes a crushing net 221, which is located at the screening port 2101 and connected to the discharge pipe assembly 210. In this embodiment, when the material passes through the crushing net 221, the crushing net 221 crushes the material, and the material falls into the storage chamber 231 after passing through the mesh of the crushing net 221 after being crushed. By providing the crushing net 221, not only can the screening assembly 220 crush the material, but also the material can fall into the storage chamber 231 after passing through the screening assembly 220, thereby avoiding the problem that the screening assembly 220 blocks the normal transportation of the material.

[0055] like Figure 4As shown, in some embodiments, the screening assembly 220 further includes a spike portion 222, which is connected to the upper side of the crushing net 221, and the tip of the spike portion 222 faces the upper side of the crushing net 221, and the vibration of the vibrator 240 can be transmitted to the spike portion 222. In this embodiment, the spike portion 222 pierces the agglomerated material when the material passes through, thereby improving the efficiency of breaking the material and preventing the problem of the material blocking the crushing net 221.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the discharge pipe assembly 210 is provided with a maintenance port 2102, which is located on the upper side of the screening assembly 220, and the discharge mechanism 200 further includes a removable cover plate 250, which is located in the maintenance port 2102 and is detachably connected to the discharge pipe assembly 210. In this embodiment, when the screening assembly 220 is blocked or damaged, the removable cover plate 250 is opened to inspect and clean the screening assembly 220, thereby improving the convenience of maintaining the screening assembly 220.

[0057] like Figure 1 As shown, in some embodiments, the discharging mechanism 200 further includes a handle 260, and the handle 260 is connected to the surface of the removable cover 250. In this embodiment, the removable cover 250 is moved by the handle 260, which improves the convenience of opening the maintenance port 2102.

[0058] like Figure 1 As shown, further, the removable cover plate 250 is provided with an observation window 251, through which the screening assembly 220 can be observed, so as to promptly discover problems with the screening assembly 220.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, the discharge pipe assembly 210 includes a docking pipe 211 and a screening pipe 212, the adjustment sleeve 310 is rotatably sleeved on the input end of the docking pipe 211, an output port 2111 is provided on the lower side of the docking pipe 211, the input end and the output end of the screening pipe 212 are connected, the screening port 2101 is provided on the lower side of the screening pipe 212, and the maintenance port 2102 is provided on the upper side of the screening pipe 212.

[0060] like Figure 5As shown, in other embodiments, the rotation drive assembly 340 includes a driving motor 341, a driving gear 345 and a driven gear 346. The driving motor 341 is installed on the feeding mechanism 100 or the discharging mechanism 200. The driving gear 345 is fixedly sleeved on the output shaft of the driving motor 341. The driven gear 346 is fixedly sleeved on the adjustment sleeve 310. The driven gear 346 is meshed with the driving gear 345, and the driven gear 346 is meshed with the driving gear 345. In this embodiment, the driving motor 341 drives the driving gear 345 to rotate, the driving gear 345 drives the driven gear 346 to rotate, and the driven gear 346 drives the adjustment sleeve 310 to rotate, thereby realizing the automatic rotation of the adjustment sleeve 310.

[0061] like Figure 1 As shown, the present disclosure further provides a vibration screening system, a vibration screen 20 and a discharge device 10 as described in any of the above embodiments, wherein the feed end of the vibration screen 20 is connected to the discharge end of the discharge mechanism 200 .

[0062] like Figures 1 to 4 As shown, in one embodiment, before unloading, the driving motor 341 drives the lever 342 to rotate, the lever 342 drives the rotating plate 343 to rotate, the rotating plate 343 drives the adjusting sleeve 310 to rotate, and the adjusting sleeve 310 drives the moving stopper 330 to rotate, so as to adjust the size of the adjustable opening 301 between the moving stopper 330 and the fixed stopper 320 to a suitable value, and then the driving motor 341 stops to fix the lever 342, the rotating plate 343, the adjusting sleeve 310 and the moving stopper 330, and then pour the material into the feeding mechanism 100, and the feeding mechanism The vibration motor 110 of 100 vibrates to promote the flow of materials. The materials in the feeding mechanism 100 enter the docking tube 211 through the adjustable opening 301, and then the materials in the docking tube 211 enter the screening tube 212. Then the crushing net 221 and the spike portion 222 crush the materials under the vibration of the vibrator 240. The crushed materials fall into the storage cavity 231 through the mesh of the crushing net 221, and then enter the feeding end of the vibrating screen 20 through the discharge port 232. After pushing the materials for a certain period of time, the materials are stopped from being pushed to stop unloading, thus completing one unloading.

[0063] Compared with the prior art, the present invention has at least the following advantages:

[0064] By rotating the adjusting sleeve 310, the adjusting sleeve 310 drives the moving stopper 330 to rotate so as to adjust the size of the adjustable opening 301 between the moving stopper 330 and the fixed stopper 320. Since the material passes through the adjustable opening 301 when unloading, the material flow rate can be adjusted by adjusting the size of the adjustable opening 301, so that the unloading amount per unit time can be adjusted; since the adjusting sleeve 310 is fixed when unloading, the adjusting sleeve 310 will not rotate after the unloading device 10 is used for a long time, so that the stability of the adjusting sleeve 310 and the moving stopper 330 is relatively high, the dimensional stability of the adjustable opening 301 is improved, and the feeding stability of the unloading device 10 is improved.

[0065] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
