Description

Technical Field

[0001] The present invention relates to the technical field of bagged rare earth sampling devices, and particularly to a continuous sampling device for bagged rare earths. Background Art

[0002] With the rapid development of emerging industries such as new energy vehicles and intelligent manufacturing, since rare earth is an important non-renewable strategic resource, with the large-scale exploitation of rare earth minerals in recent years, the reduction of rare earth mineral resources has led to the rapid growth of the global rare earth recycling market. Rare earth sampling is a very important task in the links of rare earth production, trade, and scientific research. Accurately obtaining representative rare earth samples is to accurately analyze and detect the composition, content, physical properties, etc. of rare earths, providing a basis for the mining, processing, sales, and quality control of rare earths.

[0003] At present, most of the sampling for rare earth recycling is carried out by manual unloading and sampling. Such a working method has a large manual labor intensity, a slow sampling rhythm, and the accuracy and uniformity of sampling cannot be guaranteed. Due to the large daily output, unloading and sampling are completed by different people, resulting in a high labor cost input. The accuracy and uniformity of manual sampling cannot be guaranteed, and the efficiency of manual sampling is low. Therefore, we propose a continuous sampling device for bagged rare earths. Summary of the Invention

[0004] The purpose of the present invention is to provide a continuous sampling device for bagged rare earths to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A continuous sampling device for bagged rare earths includes an unloading belt conveyor, a distributing belt conveyor, a pushing mechanism, a fixed distributing mechanism, a left pre-sampling belt conveyor, and a right pre-sampling belt conveyor. A fast belt conveyor is installed at the rear end of the unloading belt conveyor, and a distributing belt conveyor is installed at the rear end of the fast belt conveyor. A pushing mechanism is installed in the middle of the upper end of the distributing belt conveyor, and a fixed distributing mechanism is installed along the center line at the rear end of the distributing belt conveyor. The left pre-sampling belt conveyor and the right pre-sampling belt conveyor are installed on both sides of the fixed distributing mechanism at the rear end of the distributing belt conveyor.

[0006] Preferably, a left sampling belt conveyor is installed at the rear end of the left pre-sampling belt conveyor, and a left sampling mechanism is installed in the middle of the upper end of the left sampling belt conveyor.

[0009] Preferably, a right flipping and rejecting belt line is arranged at the rear end of the right sampling belt line, and a right lifting and docking belt line is arranged at the rear end of the right flipping and rejecting belt line.

[0010] Preferably, the pushing mechanism includes a pushing support frame, a pushing cylinder and a pushing plate, and the pushing cylinder is welded to the middle part of the pushing support frame, the end bolts of the pushing cylinder are fastened with the pushing plate, and the pushing support frame is threadedly fastened to the middle upper end of the material distribution belt line.

[0011] Preferably, a protective frame is welded on one side of the outer wall of the unloading belt line, and elevated baffles are welded on both sides of the unloading belt line along the conveyor belt.

[0012] Preferably, the fixed material dividing mechanism includes a fixed splint, a material dividing baffle, and a tightening groove plate. A tightening groove plate is welded to the lower middle end of the fixed splint, and the tightening groove plate is fastened with a material dividing baffle along the tightening groove bolts.

[0014] Compared with the prior art, the beneficial effects of the present invention are: when the continuous sampling device for bagged rare earths is used, the device adopts a conveyor belt for transportation, which can save a lot of manpower, reduce the labor intensity of workers, and reduce the risk of injury. At the same time, the left belt line system and the right belt line system divide the material bags in an orderly manner, thereby improving the sampling efficiency of bagged rare earths, improving the accuracy and uniformity of sampling, and effectively avoiding unreliable sampling caused by improper manual operation.

[0015] This device controls the conveying speed of the belt conveyor line. The gradually increasing speed can smoothly open the intervals between the material bags.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5, the present invention provides a technical solution: a continuous sampling device for bagged rare earths, including a truck unloading belt line 1, a material distributing belt line 3, a pushing mechanism 4, a fixed material distributing mechanism 5, a left pre-sampling belt line 6 and a right pre-sampling belt line 11. A fast belt line 2 is installed at the rear end of the truck unloading belt line 1, and a material distributing belt line 3 is installed at the rear end of the fast belt line 2. A pushing mechanism 4 is installed in the middle of the upper end of the material distributing belt line 3, and a fixed material distributing mechanism 5 is installed along the center line at the rear end of the material distributing belt line 3. The left pre-sampling belt line 6 and the right pre-sampling belt line 11 are installed on both sides of the fixed material distributing mechanism 5 at the rear end of the material distributing belt line 3. A left sampling belt line 7 is installed at the rear end of the left pre-sampling belt line 6, and a left sampling mechanism 8 is installed in the middle of the upper end of the left sampling belt line 7. A left flipping and rejecting belt line 9 is installed at the rear end of the left sampling belt line 7, and a left lifting and docking belt line 10 is installed at the rear end of the left flipping and rejecting belt line 9. A right sampling belt line 12 is installed at the rear end of the right pre-sampling belt line 11, and a right sampling mechanism 13 is installed in the middle of the upper end of the right sampling belt line 12. A right flipping and rejecting belt line 14 is installed at the rear end of the right sampling belt line 12, and a right lifting and docking belt line 15 is installed at the rear end of the right flipping and rejecting belt line 14. The left pre-sampling belt line 6, the left sampling belt line 7, the left sampling mechanism 8, the left flipping and rejecting belt line 9 and the left lifting and docking belt line 10 form a left belt line system, and the right pre-sampling belt line 11, the right sampling belt line 12, the right sampling mechanism 13, the right flipping and rejecting belt line 14 and the right lifting and docking belt line 15 form a right belt line system. The left belt line system and the right belt line system distribute the material bags in an orderly manner, improving the sampling efficiency of bagged rare earths. At the same time, flipping and rejecting belt lines are provided in both the left belt line system and the right belt line system to reject the material bags containing foreign objects through the flipping and rejecting belt lines.

[0024] The pushing mechanism 4 includes a pushing support frame 16, a pushing cylinder 17 and a pushing plate 18. The pushing cylinder 17 is welded in the middle of the pushing support frame 16, and the pushing plate 18 is bolted to the end of the pushing cylinder 17. The pushing support frame 16 is threadedly fastened to the middle upper end of the material distributing belt line 3. By the action of the pushing cylinder 17, the material bags are evenly distributed to the left and right two belt lines, thus alleviating the situation that the subsequent sampling rhythm is insufficient.

[0025] A protective frame 19 is welded on one side of the outer wall of the truck unloading belt line 1, and heightening baffles 20 are welded on both sides of the truck unloading belt line 1 along the conveyor belt. The heightening baffles 20 serve as protective baffles for the truck unloading belt line 1 to reduce the situation of material bags falling off the truck unloading belt line 1 and ensure the effective conveyance of the material bags. The protective frame 19 serves as a shielding support, and protective components such as a sunshade net can be laid on the protective frame 19 to provide shielding protection for the handling personnel.

[0026] The fixed material distribution mechanism 5 includes a fixed clamping plate 21, a material distribution baffle 22, and a waist tightening groove plate 23. The lower end of the middle part of the fixed clamping plate 21 is welded with the waist tightening groove plate 23, and the material distribution baffle 22 is bolted to the waist tightening groove plate 23 along the waist tightening groove. The material distribution baffle 22 is distributed in a V shape, and the included angle size of the material distribution baffle 22 is adjusted through the waist tightening groove plate 23. The fixed clamping plate 21 is distributed along the rear end of the material pushing support frame 16, and the fixed clamping plate 21 is bolted to the material distribution belt line 3. As a material distribution component, the fixed material distribution mechanism 5 has its material distribution baffle 22 designed with an overall V-shaped structure, which can effectively meet the requirement of separating the material bags left and right. At the same time, the included angle of the material distribution baffle 22 is adjustable. When the material distribution baffle 22 needs to be adjusted, the screws between the material distribution baffle 22 and the waist tightening groove plate 23 can be loosened, and the material distribution baffle 22 is forced outwards. The screws slide along the waist tightening groove in the waist tightening groove plate 23. After the adjustment of the material distribution baffle 22 is completed, the screws at the connection are tightened again. This adjustment method is simple to operate and convenient for users to use.

[0027] Working principle: For this kind of continuous sampling device for bagged rare earths, first, the material bags are manually unloaded from the vehicle onto the unloading belt line 1 by workers. The materials are accelerated by the fast belt line 2, so that the intervals between the materials are widened. The material bags enter the material distribution belt line 3. At this time, the material pushing mechanism 4 acts, and its material pushing cylinder 17 drives the material pushing plate 18 to act intermittently. The intermittently acting material pushing plate 18 distributes the material bags orderly to the left sampling front belt line 6, the left sampling belt line 7, the left sampling mechanism 8, the left turning and rejecting belt line 9, and the left lifting and docking belt line 10, which form the left belt line system, and the right sampling front belt line 11, the right sampling belt line 12, the right sampling mechanism 13, the right turning and rejecting belt line 14, and the right lifting and docking belt line 15, which form the right belt line system. In the left and right belt line systems, when the material bags reach the sampling areas of the sampling belt lines of the left sampling belt line 7 and the right sampling belt line 12, the sampling mechanisms of the left sampling mechanism 8 and the right sampling mechanism 13 automatically act to complete sampling. If there are abnormal materials in the material bags, it will cause the cylinder to fail to run to the set position. At this time, the left turning and rejecting belt line 9 and the right turning and rejecting belt line 14 start to turn and reject the material bags.
