Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In a specific embodiment provided by the present invention, the material hoist mainly includes a lifting frame 1, a driving mechanism 2, a connecting frame 3, a hopper fixing frame 4, a movable hopper 5, a sliding frame 6 and a weighing slide 7. The driving mechanism 2 is installed on the lifting frame 1, one end of the connecting frame 3 is connected to the driving mechanism 2, and the other end of the connecting frame 3 is hinged to the hopper fixing frame 4. The hopper fixing frame 4 has an opening for disassembling and removing the movable hopper 5. The weighing slide 7 is located at the bottom of the hopper fixing frame 4. The movable tray 71 of the weighing slide 7 can carry the hopper fixing frame 4 and move horizontally along the weighing slide 7. The sliding frame 6 can be slidably arranged on the side outer wall opposite to the opening, and the sliding frame 6 is against the fixed plate 51 of the outer wall of the movable hopper 5.

[0028] Among them, the driving mechanism 2 is used to drive the hopper fixing frame 4 to move up and down through the connecting frame 3, the hopper fixing frame 4 is used to carry the movable hopper 5, the movable hopper 5 is used to carry materials, the weighing slide 7 is installed at the bottom of the lifting frame 1, and the movable tray 71 of the weighing slide 7 is used to carry the movable hopper 5 and move on the weighing slide 7.

[0029] After the material is loaded, the movable tray 71 sends the movable hopper 5 to the hopper fixed frame 4 again. When the movable tray 71 stops at the specified position of the hopper fixed frame 4, the elevator drives the hopper fixed frame 4 to rise, and the hopper fixed frame 4 supports the bottom of the movable hopper 5 and rises together, achieving the purpose of moving materials.

[0030] In order to optimize the advantages of the material elevator in the above embodiment that the movable hopper 5 can be separated from the elevator more automatically and the weighing is more automated, the weighing slide 7 includes a weighing device 72, a slide 73, a screw 74 and a drive motor 75. The screw 74 is arranged on the output shaft of the drive motor 75, the slide 73 runs through the weighing device 72, the screw 74 is arranged between the slides 73, and the movable tray 71 cooperates with the screw 74 in a spiral transmission. When the material is transferred, the movable hopper 5 is lowered to the bottom of the elevator and supported by the movable tray 71. Then, the weighing slide 7 is started. It is only necessary to drive the motor 75 to start the driving screw 74. Then, due to the rotation transmission of the screw 74 and the movable tray 71, the rotation of the screw 74 will drive the movable tray 71 to move toward the weighing device 72 through the slide 73. When the movable hopper 5 moves to the weighing device 72, the driving motor 75 stops working, and the movable hopper 5 will be placed on the weighing device 72, and then the movable hopper 5 will be loaded. This process is automatically controlled by the control system, and a detection device may be included when the movable hopper 5 reaches the movable tray 71, so that the next operation of the movable hopper 5 can be performed. Of course, the weighing of this link will also be very automated, and a weight detection device may be included to return the movable hopper 5 to the hopper fixing frame 4 after weighing and loading are completed, so as to achieve more automated control. At the same time, the design of the slide 73 can ensure the stability of the movable hopper 5 during the movement and improve the efficiency of material transfer.

[0031] Based on the above-mentioned disengagement and fixation links between the movable hopper 5 and the hopper fixed frame 4, a spring 8 is mounted on the sliding frame 6; a limiter 9 is provided on the lifting frame 1, and the limiter 9 is located below the sliding frame 6; the sliding frame 6 is provided with a pressure plate 61 that abuts against the fixed plate 51. In the process of transferring materials, when the movable hopper 5 descends to the bottom of the elevator, the limiter 9 at the bottom of the elevator presses against the sliding frame 6, and the movable hopper 5 contacts the movable tray 71, but the hopper fixed frame 4 continues to descend until it reaches the lower limit of the elevator, and the elevator stops working. The fixed plate 51 on the movable hopper 5 is completely disengaged from the pressure plate 61 on the hopper fixed frame 4, and the movable tray 71 completely supports the movable hopper 5; in addition, when the movable hopper 5 is loaded with materials and returns to the hopper fixed frame 4, the movable tray 71 stops. After stopping at the specified position of the hopper fixing frame 4, the hoist drives the hopper fixing frame 4 to rise, and at the same time, the hopper fixing frame 4 supports the bottom of the movable hopper 5 and rises together, the limiter 9 is disengaged from the sliding frame 6, and the sliding frame 6 pulls down the pressure plate 61 through the spring 8, so that the pressure plate 61 buckles the fixed plate 51 above the movable hopper 5, thereby achieving the purpose of fixing the movable hopper 5. The movable hopper 5 is automatically disengaged from or fixed on the hopper fixing frame 4 through the mechanical structure, which improves the degree of automation of the present invention, reduces labor, and improves the efficiency of material loading and transfer.

[0032] It should be noted that the inclined surface of the fixed plate 51 forms an angle of 30° to 60° with the outer wall of the movable hopper 5; the inclined surface of the pressing plate 61 has the same inclination angle as the inclined surface of the fixed plate 51. When the movable hopper 5 is separated from and fixed to the hopper fixing frame 4, it is achieved through the fixed plate 51. Therefore, here the fixed plate 51 is set as an inclined surface and is set at an angle of 30° to 60° with the outer wall of the movable hopper 5. This can improve the efficiency and effectiveness of the separation and fixation of the movable hopper 5 and the hopper fixing frame 4. In addition, the pressing plate 61 with the same inclination angle further enhances the above-mentioned effect, making the separation and fixation of the movable hopper 5 smoother.

[0033] Furthermore, the number of the sliding frames 6 is 1 to 3, and they are arranged between the rollers of the hopper fixing frame 4. Multiple sliding frames 6 can ensure the accuracy of fixing with the movable hopper 5, avoid the occurrence of the situation where the fixing is not formed, and ensure that the movable hopper 5 can perform normal movement and conveying operations.

[0034] In summary, the material elevator provided in this embodiment mainly includes a lifting frame, a driving mechanism, a connecting frame, a hopper fixing frame, a movable hopper, a sliding frame and a weighing slide. The driving mechanism is installed on the lifting frame, one end of the connecting frame is connected to the driving mechanism, and the other end of the connecting frame is hinged to the hopper fixing frame. The hopper fixing frame has an opening for disassembling and removing the movable hopper. The weighing slide is located at the bottom of the hopper fixing frame. The movable tray of the weighing slide can carry the hopper fixing frame and move horizontally along the weighing slide. The sliding frame can be slidably arranged on the side outer wall opposite to the opening, and the sliding frame is against the fixed plate of the outer wall of the movable hopper. The present invention realizes separation and fixation from the hopper fixing frame when the movable hopper moves up and down by arranging the sliding frame and the fixed plate of the movable hopper, thereby solving the problem in the prior art that the movable hopper cannot be automatically separated from the elevator, thereby improving the working efficiency of the elevator.
