[0036] To keep the following description of the embodiments of the present invention clear and concise, the detailed descriptions of known functions and known components are omitted in the present invention.

[0037] Embodiment 1

[0038] Please refer to Figures 1 - 8 As shown, in this embodiment, a semi-automatic lifting mixing hopper is provided, including: a lifting frame 1, a moving frame 2, and a hopper 3.

Two through fixing holes 9 are opened on one side of each fixing plate 8. One end of each rotating shaft 10 is provided with a bearing seat 11. The rotating shafts 10 rotate freely relative to the bearing seats 11. Connecting plates 12 are fixedly bolted to the bottoms of the bearing seats 11. The hopper 3 can rotate on the moving frame 2, which is convenient for changing the position of the discharge valve 19, thereby realizing discharging and feeding. At the same time, it can be separated from the moving frame 2, which is convenient for lifting;

[0039] Two positioning components for fixing the connecting plates 12 and the fixing plates 8 are arranged at the top of the moving frame 2. The two positioning components are symmetrically arranged. The positioning component includes a C-shaped sliding frame 13. The sliding frame 13 is slidably connected to one side of the moving frame 2. Inclined driving surfaces 14 are arranged at both bending parts of the sliding frame 13. An intermediate frame 15 is fixedly connected to one side of the sliding frame 13. A first tension spring 16 is fixedly connected between the intermediate frame 15 and the moving frame 2. An F-shaped inserting frame 17 is fixedly connected to one side of the intermediate frame 15. One end of the inserting frame 17 is inserted into the connecting plate 12, and the other end of the inserting frame 17 penetrates through the moving frame 2 and is inserted into one of the fixing holes 9. When the sliding frame 13 moves, it can drive the intermediate frame 15 and the inserting frame 17 to move, thereby enabling the inserting frame 17 to be disengaged from the insertion with the connecting plate 12 and the fixing plate 8, and then releasing the fixation of the hopper 3, which is convenient for the hopper 3 to move;

[0040] A lifting mechanism is arranged on one side of the lifting frame 1 for lifting the hopper 3.

[0041] In the present invention, the lifting mechanism includes a sliding frame 4, which is slidably connected to one side of the lifting frame 1. A threaded rod 39 penetrates through the sliding frame 4 and is threadedly connected between the top and bottom of the sliding frame 4. The top and bottom of the threaded rod 39 are rotatably connected to the lifting frame 1. One side of the sliding frame 4 is fixedly connected to a C-shaped lifting frame 5. The surface of the lifting frame 5 is fixedly connected with two pairs of limiting blocks 25, and the two pairs of limiting blocks 25 are respectively used in cooperation with two hexagonal prisms 7. The two ends of the lifting frame 5 are respectively used in cooperation with the driving surfaces 14 on the two sliding frames 13. When the sliding frame 4 and the lifting frame 5 are moved upward, during the upward movement of the lifting frame 5, it can push the sliding frame 13 to move through the driving surface 14, thereby releasing the fixation of the hopper 3. Subsequently, the limiting block 25 contacts the hexagonal prism 7, thereby lifting the hopper 3, and the hexagonal prism 7 and the limiting block 25 are used to prevent the hopper 3 from rotating, avoiding manual operation, and improving the safety of operation and the automation degree of the device.

[0042] Particularly, a worm gear 38 is fixedly connected to the circumference of the threaded rod 39, and a motor 6 is fixedly connected to one side of the lifting frame 1. One end of the output shaft of the motor 6 is fixedly connected to a worm 37, and the worm 37 meshes with the worm gear 38. When the motor 6 is started, the motor 6 drives the threaded rod 39 to rotate through the worm 37 and the worm gear 38, thereby driving the sliding frame 4 and the lifting frame 5 to move.

[0043] Embodiment Two

[0044] On the basis of Embodiment One: Refer to the attached Figures 1 - 8 .

[0045] In the present invention, two through ejector rods 21 are inserted into one side of the sliding frame 4. One ends of the ejector rods 21 are in contact with the hopper 3 in the lifted state. Second springs 22 are fixedly connected between the ejector rods 21 and the sliding frame 4. Two avoidance channels are provided on one side of the lifting frame 1, and the ejector rods 21 are respectively located in the two avoidance channels. The ejector rods 21 can move, so that the hopper 3 is collided by the ejector rods 21, avoiding raw materials from adhering to the hopper 3 and improving the accuracy of material feeding.

[0046] Particularly, a driving plate 23 is fixedly connected to one side of the lifting frame 1. The driving plate 23 is located between the two avoidance channels. A plurality of uniformly distributed driving grooves 24 are formed on one side of the driving plate 23. A fixed shaft 26 is fixedly connected between the two ejector rods 21. Two rotating plates 27 are rotatably connected to the circumference of the fixed shaft 26. The rotating plates 27 are used in cooperation with the driving grooves 24. Torsion springs 29 are fixedly connected between the rotating plates 27 and the adjacent ejector rods 21. Two limiting frames 28 for limiting the rotating plates 27 are fixedly connected to the circumference of the fixed shaft 26. The ejector rods 21 drive the rotating plates 27 to move through the fixed shaft 26. The rotating plates 27 pass through a plurality of driving shafts 24 under the limitation of the limiting frames 28. The driving grooves 24 cause the ejector rods 21 to move, and under the action of the second springs 22, the hopper 3 is collided, causing the hopper 3 to vibrate.

[0047] It should be noted that a counterweight 32 is slidably connected to one side of the lifting frame 1, a guide wheel 30 is rotatably connected to the top of the lifting frame 1, a pulling rope 31 is fixedly connected to the top of the sliding frame 4, the other end of the pulling rope 31 bypasses the guide wheel 30 and is fixed to the counterweight 32, and the pulling rope 31 and the guide wheel 30 are wound around at least one circle. By balancing the weight of the hopper 3 with the counterweight 32, the lifting difficulty of the hopper 3 is reduced, the wear of the device is reduced, and the service life of the device is prolonged.

[0048] In the present invention, a plurality of guide rails 33 are fixedly connected to both sides of the guide wheel 30. One end of each guide rail 33 far from the rotation point of the guide wheel 30 is slidably connected with a sliding plate 34. A second tension spring 35 is fixedly connected between the sliding plate 34 and the guide rail 33. An anti-falling plate 36 is fixedly connected to one side of the lifting frame 1. After the sliding plate 34 is thrown out by centrifugal force, it abuts against one side of the anti-falling plate 36. When the sliding frame 4 falls rapidly, the guide wheel 30 can be driven to rotate rapidly through the friction between the pulling rope 31 and the guide wheel 30, and then the sliding plate 34 can be thrown out by centrifugal force, and then abuts against the anti-falling plate 36, so that the guide wheel 30 stops rotating, and the falling speed of the hopper 3 is reduced by using the friction, improving the safety of use.

[0049] Particularly, two pairs of ingot-shaped positioning blocks 18 are fixedly connected to the top of the moving frame 2. Two notches are respectively opened at the bottom of the connecting plate 12. The positioning blocks 18 are respectively inserted into the notches. By matching the positioning blocks 18 with the notches, the connecting plate 12 and the hopper 3 can be conveniently moved to the accurate positions above the moving frame 2.

[0050] It should be noted that a plurality of universal wheels are fixedly connected to the bottom of the moving frame 2, and the universal wheels facilitate the movement of the moving frame 2.

[0051] In the present invention, two symmetrically arranged guide plates 20 are fixedly connected to the bottom of the moving frame 2. Two guide rods 41 are fixedly connected to the bottom of the lifting frame 1. A positioning plate 40 is slidably connected between the two guide rods 41. Two third springs 42 are fixedly connected between the positioning plate 40 and the bottom of the lifting frame 1. The two third springs 42 are respectively sleeved on the circumferences of the two guide rods 41. A first guiding inclined surface 43 is opened on the surface of the positioning plate 40. Second guiding inclined surfaces 44 are opened on both sides of the positioning plate 40. The second guiding inclined surfaces 44 are used in cooperation with the two guide plates 20. By the second guiding inclined surfaces 44, the moving frame 2 and the lifting frame 1 are kept aligned. At the same time, the moving frame 2 presses down the positioning plate 40 through the first guiding inclined surface 43, and then the approaching speed of the moving frame 2 can be reduced by using the friction, effectively preventing impact, and at the same time, the moving frame 2 can be positioned, facilitating the lifting of the hopper 3.

[0052] The use process and working principle of the technical solution of the present invention are as follows:

[0053] When in use, the mobile frame 2 is moved to one side of the lifting frame 1. During the movement, the guide plate 20 moves to one side of the second guide slope 44, and the mobile frame 2 is kept aligned with the lifting frame 1 through the second guide slope 44. At the same time, the mobile frame 2 presses the positioning plate 40 downward through the first guide slope 43, and then the friction force can be used to reduce the speed of the mobile frame 2 approaching, effectively preventing collision, and at the same time, it can play a positioning effect on the mobile frame 2, which is convenient for lifting the hopper 3;

[0054] Before the moving frame 2 moves to the side of the lifting frame 1, it is necessary to start the motor 6. The motor 6 drives the threaded rod 39 to rotate through the worm 37 and the worm gear 38, thereby dropping the sliding frame 4 and the lifting frame 5. After the moving frame 2 moves into place, the sliding frame 4 and the lifting frame 5 are moved up in the same way. During the upward movement of the lifting frame 5, the sliding frame 13 is first pushed to move by the driving surface 14, and the sliding frame 13 drives the intermediate frame 15 and the plug-in frame 17 to move. The plug-in frame 17 is disengaged from the plugging with the connecting plate 12 and the fixed plate 8, thereby releasing the fixation of the hopper 3. Subsequently, the limit block 25 contacts the hexagonal prism 7, thereby lifting the hopper 3, and the hexagonal prism 7 and the limit block 25 are used to prevent the hopper 3 from rotating. After lifting into place, the discharge valve 19 is opened, thereby enabling the discharge of the raw materials in the hopper 3, thereby improving the degree of automation of the device, reducing manual operation, and reducing the danger during manual operation.

[0055] During the descent of the hopper 3, the slide frame 13 moves in the same way. When the hopper 3 has not completely fallen, the hopper 3 can be rotated so that the discharge valve 19 faces upwards, which is convenient for feeding. After the rotation is completed, the hopper 3 is dropped and the connecting plate 12 and the fixing plate 8 are fixed by the bracket 17 to prevent the hopper 3 from rotating and facilitate transfer.

[0056] In the process of the hopper 3 moving up and down, the counterweight block 32 reduces the difficulty of lifting and lowering the hopper 3, reduces the wear of the device, and increases the service life of the device. When the sliding frame 4 falls quickly, the friction between the pull rope 31 and the guide wheel 30 can drive the guide wheel 30 to rotate quickly, and then the slide plate 34 can be thrown out by the centrifugal force, and then it conflicts with the anti-falling plate 36, so that the guide wheel 30 stops rotating, and the friction force is used to reduce the falling speed of the hopper 3, thereby improving the safety of use.

[0057] When the sliding frame 4 drops, it also drives the ejector rod 21 to move. The ejector rod 21 drives the rotating plate 27 to move through the fixed shaft 26. The rotating plate 27 passes through a plurality of drive shafts 24 under the restriction of the limit frame 28, and the ejector rod 21 moves through the drive groove 24, and collides with the hopper 3 under the action of the second spring 22, avoiding the adhesion of raw materials in the hopper 3 and improving the accuracy of feeding. When the sliding frame 4 rises, the rotating plate 27 lacks restriction and can rotate freely without getting stuck with the drive plate 23. When the rotating plate 27 moves to the top, it is reset under the action of the torsion spring 29, facilitating reuse.
