Therefore, a deformed hopper cannot be used to transport materials. Furthermore, a deformed hopper can scrape against the elevator chassis, damaging it or breaking the elevator chain. Existing hopper correction technology lacks, forcing deformed hoppers to be scrapped or melted down for rebuilding, wasting resources and reducing efficiency. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0026] Figure 1 The schematic diagram of the overall structure of the correction device of the bucket elevator hopper 6 of the utility model is as follows: Figure 1 As shown, the utility model discloses a correction device for a bucket elevator hopper 6, comprising a frame 1, a base 2 and a pressure rod 3. The frame 1 is fixedly connected to the upper surface of the base 2, and a through hole 31 is provided at the top of the frame 1. One end of the pressure rod 3 passes through the through hole 31 and extends into the frame 1, and the other end is provided with a crank 32. A correction platform 4 is provided in the frame 1, which is fixed to the upper surface of the base 2 and is located directly below the pressure rod 3. A correction groove 41 is provided on the surface of the correction platform 4. The inclination angle of the correction groove 41 is the same as that of the hopper 6. A punch 5 is provided between the correction groove 41 and the pressure rod 3. The shape of the punch 5 is the same as that of the hopper 6. The hopper 6 to be corrected is provided between the punch 5 and the correction platform 4. The pressure rod 3 applies pressure to the punch 5 below, and the punch 5 and the correction groove 41 of the correction platform 4 squeeze the hopper 6 to be corrected to restore it to its normal shape.

[0027] The correction device also includes a pressure plate 7, which is arranged between the pressure rod 3 and the punch 5. The pressure rod 3 applies pressure to the punch 5 through the pressure plate 7 to prevent the punch 5 from being deformed due to excessive force at the contact point between the pressure rod 3 and the pressure rod 3. A groove 71 is provided at the center of the pressure plate 7, which is located corresponding to the pressure rod 3. When the pressure rod 3 moves downward and contacts the pressure plate 7, it contacts the groove 71 to prevent the pressure rod 3 from being offset due to the force after contacting the pressure plate 7, so that the pressure of the pressure rod 3 remains perpendicular to the pressure plate 7. During the hopper correction process, the pressure plate 7 contacts the upper surface of the hopper 6. Since the shape of the pressure plate 7 is larger than that of the hopper 6, the correction is completed when the pressure plate 7 contacts the upper surface of the correction platform 4 during the downward pressing process. This can prevent the pressure rod 3 from applying excessive pressure and causing the hopper 6 to fall from the correction slot 41.

[0028] A nut 33 is provided at the through hole 31 , and an outer surface of the pressure rod 3 is provided with an external thread, which cooperates with the nut 33 . The pressure rod 3 is raised or lowered by rotating the crank 32 in different directions.

[0029] Preferably, the pressure rod 3 can be set as a hydraulic rod, and the up and down movement of the pressure rod 3 can be controlled by hydraulic pressure, or the pressure rod 3 can be connected to an electric motor to control the movement of the pressure rod 3.

[0030] Figure 2 This is a top view of the structure of the correction platform 4 of the utility model. Figure 3 This is a side view of the structure of the correction platform 4 of the utility model, as shown Figure 2 and 3 As shown, the correction platform 4 is a hollow structure, including a correction plate 42 and two side walls 43. The correction groove 41 is arranged at the center of the correction plate 42. The side walls 43 of the correction groove 41 are inclined surfaces, and the inclination angle is the same as that of the hopper 6 and the punch 5, so that it fits closely with the inner shape of the hopper 6 to ensure the original design inner size and shape of the hopper 6. According to the actual angle setting of the hopper 6, the inclination angle of one side in this application is 50 degrees.

[0031] A telescopic plate 44 for adjusting the size of the correction slot 41 is provided in the correction plate 42. The telescopic plate 44 is slidably connected to the correction plate 42 and is provided in the correction plate 42. When the size of the hopper 6 is smaller than the width of the correction slot 41, the telescopic plate 44 is extended to a suitable position and fixed, and as the pressure rod 3 moves downward to generate pressure, the distance between the inner walls of the hopper 6 gradually increases, and the telescopic plate 44 shrinks inward synchronously. The thickness of the hopper 6 is about 1.8 mm, and the thickness of the correction plate 42 is 2 to 3 cm. The entire correction device is made of stainless steel.

[0032] Figure 4 Schematic diagram of the working of the correction device of the bucket elevator hopper 6 of the present invention. Figure 4As shown, when working, first place the hopper 6 that needs to be corrected into the correction slot 41 of the correction platform 4 at a suitable angle, ensure that the four sides of the hopper 6 are engaged with the inner wall of the correction slot 41, and adjust the telescopic distance of the telescopic plate 44 in the correction plate 42 according to the size of the hopper 6 so that it is in close contact with the outer wall of the hopper 6. The punch 5 is placed into the hopper 6 according to the shape of the hopper 6, and a pressure plate 7 is fixed above the punch 5. The groove 71 in the center of the pressure plate 7 corresponds to the position of the pressure rod 3 above. The pressure rod 3 is started. Hydraulics can be used, or the crank 32 can be turned to slowly move the pressure rod 3 downward. The pressure rod 3 applies pressure to the pressure plate 7 and transmits the pressure to the punch 5. The punch 5 drives the deformed hopper 6 to be squeezed into the correction groove 41. At the same time, the telescopic plate 44 in the correction plate 42 shrinks inward at a suitable speed and always fits tightly against the outer wall of the hopper 6. Through the effect of extrusion, the uneven places on the four sides of the hopper 6 are squeezed flat, so that the deformed hopper 6 can be corrected quickly and efficiently. When the hopper 6 and the upper surface of the correction platform 4 are in the same plane, the hopper is corrected. At this time, the pressure plate 7 is in contact with the upper surface of the correction platform 4. After the correction is completed, the pressure plate 7, the punch 5 and the hopper 6 are taken out in turn.

[0033] The utility model designs a correction device for the bucket elevator hopper, uses a pressure rod to apply downward pressure to the punch, and transmits the force to the deformed bucket. The deformed bucket is stuck in the correction groove of the correction table and is squeezed downward continuously, so the bucket is quickly corrected, and the unusable deformed bucket can be reused. The utility model is convenient and practical, saves resources, reduces the risk of scrapping, and improves work efficiency.
