[0010] Preferably, the first sleeve is threadedly connected to the spline threaded shaft, and the second sleeve is threadedly connected to the first threaded sleeve.

[0011] A usage method of a chemical raw material pouring device for chemical production use includes the following steps:

[0012] S1. First, when pouring the raw materials in the barrel into another barrel, start the electric cylinder. When the electric cylinder starts, it will push the barrel. When the bottom of the barrel is pushed, it will slide along the track of the arc-shaped sliding slot. At the same time, the upper end of the barrel will rotate on the surface of the rotating wheel through the rotating rod. When the rotating rod rotates, the spring telescopic rod at the lower end of the rotating wheel will be driven to slide in the sliding opening, which will not affect the rotation of the rotating rod. When the rotating rod rotates, it will drive the iris groove to rotate at the same time. When the iris groove rotates, it will squeeze the clamping rod. When the clamping rod is squeezed, it will drive the sliding rod to slide inward inside the rotating wheel. At the same time, the sliding rod drives the pulley to contract. The pulley gradually becomes smaller inside the slot opening. The slot opening is designed with a larger upper part and a smaller lower part. Therefore, the entire barrel will gradually contract through the pulley and then slowly slide downward inside the slot opening. And when the rotating rod rotates and moves downward, it will drive the small gear to rotate at the same time and gradually assist in moving downward through the rack;

[0013] S2. When the barrel tilts and rotates and gradually moves downward, it will drive the baffle on its surface to move downward at the same time. The shaft of the baffle will be blocked by the inclined slot opening, so that the baffle will gradually slide toward the opening inside the sliding slot. At the same time, when the baffle slides, it will drive the second sliding rod to slide at the same time. The second sliding rod will slide along the inclined plane inside the inclined slot opening. In this way, it will drive the upper end of the baffle to rotate with the lower end axis as the center and open the baffle to assist in pouring the material from the barrel.

[0014] S3. Meanwhile, when the barrel slides in the arc-shaped chute through the rotating rod, the rotating rod meshes with the arc-shaped rack through the large gear, thereby driving the rotating rod to rotate. When the rotating rod rotates, it drives the chain wheel to rotate through Chain 1. The chain wheel drives Chain Wheel 1 to rotate through the universal joint. When Chain Wheel 1 rotates, it drives the spline threaded shaft to rotate through Chain 2. The spline threaded shaft first rotates inside the spline sleeve. When the spline threaded shaft rotates, it gradually moves upward the Sleeve 1 threadedly connected to it through the thread and slides upward inside the spline sleeve. At the same time, the bottom end of Sleeve 1 will push the Threaded Sleeve 1 to gradually move upward on the surface of the spline threaded shaft. At the same time, when the spline threaded shaft rotates, it will also drive the Threaded Sleeve 1 to rotate simultaneously through its own spline rod. When the Threaded Sleeve 1 rotates, it will drive the Sleeve 2 threadedly connected to it to slide upward inside Sleeve 1. At the same time, the bottom end of Sleeve 2 will push against the Threaded Sleeve 2 to gradually move upward;

[0015] S4. When Sleeve 2 moves upward, it will squeeze Slide Bar 1. When Slide Bar 1 is squeezed, it will slide inside the hollow rod. At the same time, it slides inside the inclined slot opened in the hollow rod through the extrusion rod, causing it to slide along the inclined surface of the inclined slot. At the same time, when the extrusion rod slides and rotates, it will squeeze the inclined surface rod. When the inclined surface rod is squeezed, it will slide into the air chamber. At the same time, when the air chamber is squeezed, it will exert pressure on the hollow sealing ring, causing it to expand slightly;

[0016] S5. When Sleeve 2 slides upward, it will push the piston bottom plate to slide upward through Slide Bar 1, slowly pushing the material in the barrel outward until the pushing is completed, and there will be no remaining material left inside the barrel. After the conveying is completed, the barrel can be reset through the electric cylinder.

[0017] In the present invention, when Sleeve 2 slides upward, it will drive Slide Bar 1 to squeeze the piston bottom plate to slide upward, slowly pushing the material in the barrel outward until the pushing is completed. In this way, not only can it prevent residues from being generated on the inner wall of the barrel, but also it can ensure that all the material in the barrel is conveyed and there will be no remaining material left inside the barrel.

[0018] In the present invention, the extrusion rod slides inside the inclined slot opened in the hollow rod, causing it to slide along the inclined surface of the inclined slot. At the same time, when the extrusion rod slides and rotates, it will squeeze the inclined surface rod. When the inclined surface rod is squeezed, it will slide into the air chamber. At the same time, when the air chamber is squeezed, it will exert pressure on the hollow sealing ring, causing it to expand slightly. In this way, it can effectively prevent leakage when the piston bottom plate is working.

[0019] In the present invention, the slide bar drives the pulley to contract, and the pulley gradually becomes smaller inside the notch. The entire barrel will gradually contract through the pulley and then slowly slide downward inside the notch. In this way, when tilting to discharge materials, it will slowly approach another barrel, which can prevent material leakage.

[0020] In the present invention, when the baffle slides, it drives the second slide bar to slide simultaneously. The second slide bar slides along the inclined plane inside the inclined groove opening, which drives the upper end of the baffle to rotate around the lower end axis as the center, opening the baffle to assist the hopper in discharging materials and further preventing material leakage.

[0041] The use method and advantages of the present invention: The chemical raw material dumping device and the use method based on chemical production use, when in use, the working process is as follows:

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 ,Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 as shown in

[0043] A method for using a chemical raw material pouring device used in chemical production, comprising the following steps:

[0044] S1. First, when pouring the raw materials in the barrel 3 into another barrel, start the electric cylinder 9. When the electric cylinder 9 starts, it will push the barrel 3. When the bottom of the barrel 3 is pushed, it will slide along the track of the arc-shaped chute 4. At the same time, the upper end of the barrel 3 will rotate on the surface of the runner 57 through the rotating rod 54. When the rotating rod 54 rotates, the spring telescopic rod 53 at the lower end of the runner 57 will be driven to slide in the sliding port 55, which will not affect the rotation of the rotating rod 54. When the rotating rod 54 rotates, it will drive the iris groove 56 to rotate at the same time. When the iris groove 56 rotates, it will squeeze the clamping rod 59. When the clamping rod 59 is squeezed, it will drive the sliding rod 58 to slide inward inside the runner 57. At the same time, the sliding rod 58 drives the pulley 510 to contract, and the pulley 510 gradually becomes smaller inside the notch 52. The notch 52 is designed with a larger upper part and a smaller lower part. Therefore, the entire barrel 3 will gradually contract through the pulley 510 and then slowly slide downward inside the notch 52. In this way, when tilting and discharging materials, it will slowly approach another barrel, which can prevent material leakage. And when the rotating rod 54 rotates and moves downward, it will drive the small gear 511 to rotate at the same time and be gradually assisted downward through the rack;

[0045] S2. When the barrel 3 tilts and rotates and gradually moves downward, it will drive the baffle 83 on its surface to move downward at the same time. The shaft of the baffle 83 will be blocked by the inclined notch 81, so that the baffle 83 will gradually slide toward the opening inside the chute 82. At the same time, when the baffle 83 slides, it will drive the sliding rod two 84 to slide at the same time. The sliding rod two 84 will slide along the inclined surface inside the inclined notch 81. In this way, it will drive the upper end of the baffle 83 to rotate around the lower end axis as the center, open the baffle 83, assist the barrel 3 to pour materials, and further prevent material leakage;

[0046] S3. Meanwhile, when the barrel 3 slides in the arc-shaped chute 4 through the rotating rod 61, the rotating rod 61 meshes with the arc-shaped rack 63 through the large gear 62, thereby driving the rotation of the rotating rod 61. When the rotating rod 61 rotates, it drives the chain wheel 66 to rotate through the first chain 67. The chain wheel 66 drives the first chain wheel 68 to rotate through the universal joint 614. The rotation of the first chain wheel 68 drives the spline threaded shaft 69 to rotate through the second chain 610. The spline threaded shaft 69 first rotates inside the spline sleeve 611. When the spline threaded shaft 69 rotates, the sleeve 612 threadedly connected thereto gradually moves upward through the thread and slides upward inside the spline sleeve 611. At the same time, the bottom end of the sleeve 612 will push the first threaded sleeve 615 to gradually move upward on the surface of the spline threaded shaft 69. At the same time, when the spline threaded shaft 69 rotates, it will also drive the first threaded sleeve 615 to rotate simultaneously through its own spline rod. When the first threaded sleeve 615 rotates, it will drive the second sleeve 613 threadedly connected thereto to slide upward inside the sleeve 612. At the same time, the bottom end of the second sleeve 613 will push against the second threaded sleeve 616 to gradually move upward;

[0047] S4. When the second sleeve 613 moves upward, it will squeeze the first slide bar 78. When the first slide bar 78 is squeezed, it will slide inside the hollow rod 75. At the same time, it slides inside the inclined slot 76 opened in the hollow rod 75 through the extrusion rod 79, so that it slides along the inclined surface of the inclined slot 76. At the same time, when the extrusion rod 79 slides and rotates, it will squeeze the inclined surface rod 74. When the inclined surface rod 74 is squeezed, it will slide into the air chamber 73. At the same time, when the air chamber 73 is squeezed, it will exert pressure on the hollow sealing ring 72, causing it to expand slightly, which can effectively prevent leakage when the piston bottom plate 71 is working;

[0048] S5. When the second sleeve 613 slides upward, it will squeeze the piston bottom plate 71 to slide upward through the first slide bar 78, slowly pushing the material in the barrel 3 outward until the pushing is completed. This can not only prevent residues from being generated on the inner wall of the barrel 3, but also ensure that all the materials in the barrel 3 are transported, and there will be no remaining materials left inside the barrel 3. After the transportation is completed, the barrel 3 can be reset through the electric cylinder 9.

7. The method for using the chemical raw material dumping device based on chemical production according to claim 6, characterized in that: The following steps are involved: S1. First, when the raw material in the barrel (3) is poured into another barrel, the electric cylinder (9) is started. When the electric cylinder (9) is started, the barrel (3) is pushed. When the bottom of the barrel (3) is pushed, it slides along the track of the arc-shaped slide groove (4). At the same time, the upper end of the barrel (3) rotates on the surface of the rotating wheel (57) through the rotating rod (54). When the rotating rod (54) rotates, the spring telescopic rod (53) at the lower end of the rotating wheel (57) will passively slide in the sliding opening (55) without affecting the rotation of the rotating rod (54). When the rotating rod (54) rotates, the iris groove (56) is driven to rotate. When the iris slot (56) rotates, it squeezes the clamping rod (59). When the clamping rod (59) is squeezed, it drives the slide bar (58) to slide inward inside the rotating wheel (57). At the same time, the slide bar (58) drives the pulley (510) to shrink, and the pulley (510) gradually becomes smaller inside the slot (52). The slot (52) is designed to be larger at the top and smaller at the bottom, so the entire barrel (3) will gradually shrink through the pulley (510), thereby slowly sliding downward inside the slot (52), and when the rotating rod (54) rotates and moves downward, it drives the pinion (511) to rotate at the same time, and gradually assists downward movement through the rack; S2, when the barrel (3) tilts and rotates and gradually moves downward, the baffle (83) on the surface will be driven downward at the same time, and the axis of the baffle (83) will be blocked by the inclined slot (81), so that the baffle (83) will gradually slide toward the opening inside the slide groove (82), and when the baffle (83) slides, the second slide bar (84) will slide at the same time, and the second slide bar (84) will slide along the inclined surface inside the inclined slot (81), so that the upper end of the baffle (83) will start to rotate with the lower end axis as the center of the circle, and the baffle (83) will be opened to assist the barrel (3) in unloading; S3. At the same time, when the barrel (3) slides in the arc-shaped slide groove (4) through the rotating rod (61), the rotating rod (61) meshes with the arc-shaped rack (63) through the large gear (62), thereby driving the rotating rod (61) to rotate. When the rotating rod (61) rotates, the sprocket wheel (66) is driven to rotate through the chain 1 (67). The sprocket wheel (66) drives the sprocket wheel 1 (68) to rotate through the universal joint (614). The rotation of the sprocket wheel 1 (68) drives the spline threaded shaft (69) to rotate through the chain 2 (610). The spline threaded shaft (69) first rotates inside the spline sleeve (611). When the spline threaded shaft (69) rotates, When the sleeve 1 (612) threadedly connected thereto is gradually moved upwards through the thread, and slides upwards inside the spline sleeve (611), at the same time, the bottom end of the sleeve 1 (612) pushes the threaded sleeve 1 (615) gradually upwards on the surface of the spline threaded shaft (69), and at the same time, when the spline threaded shaft (69) rotates, the threaded sleeve 1 (615) is driven to rotate at the same time through its own spline rod, and when the threaded sleeve 1 (615) rotates, the sleeve 2 (613) threadedly connected thereto is driven to slide upwards inside the sleeve 1 (612), and at the same time, the bottom end of the sleeve 2 (613) pushes against the threaded sleeve 2 (616) and gradually moves upwards; S4, the second sleeve (613) will squeeze the slide bar (78) upward, and when the slide bar (78) is squeezed, it will slide in the hollow rod (75), and at the same time, the squeeze rod (79) will slide in the inclined groove (76) opened in the hollow rod (75), so that it will slide along the inclined surface of the inclined groove (76), and when the squeeze rod (79) slides and rotates, it will squeeze the inclined rod (74), and when the inclined rod (74) is squeezed, it will slide into the air cavity (73), and when the air cavity (73) is squeezed, it will apply pressure to the hollow sealing ring (72), causing it to expand slightly; S5. When the sleeve 2 (613) slides upward, it will squeeze the piston bottom plate (71) to slide upward through the slide rod 1 (78), and slowly push the material in the barrel (3) outward until the pushing is completed. No residual material will remain in the barrel (3). After the delivery is completed, the barrel (3) can be reset by the electric cylinder (9).
