Description

Technical Field

[0001] The utility model relates to the technical field of metering equipment, in particular to an impact-resistant metering bin. Background Art

[0002] In the mining industry, metering silos are essential equipment for storing and measuring ore and other materials. However, existing metering silos often face numerous issues during practical use, particularly during ore drop, transportation, and storage. These issues significantly impact the performance and service life of the equipment.

[0003] When ore falls into the metering bin, the impact force, due to its own weight and the drop, can be several times greater than its static pressure. In this situation, the bin's lining is susceptible to deformation. This deformation not only affects the overall structure and stability of the bin but can also lead to deviations in material metering. This requires a device to address this issue. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an impact-resistant metering bin, which solves the problem that the liner is easily deformed by the impact of falling ore.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an impact-resistant metering bin, comprising a hopper, a buffer hopper and a buffer mechanism for buffering, wherein a receiving bin is provided inside the hopper, and the buffer hopper is sleeved on the inner wall of the receiving bin;

[0006] The buffer mechanism includes a connecting rod, a connecting plate and a tension spring. The outer portion of the upper surface of the hopper is fixedly connected to an expansion plate. The top of the connecting rod is fixedly connected to the bottom of the buffer hopper, and the connecting rod passes through the expansion plate. The connecting plate is fixedly connected to the bottom of the connecting rod. The tension spring is fixedly connected to the middle portion of the upper surface of the connecting plate and the top end is fixedly connected to the bottom of the expansion plate.

[0007] A blocking mechanism is provided inside the buffer bucket to resist impact.

[0008] Optionally, the outer circumferential surface of the connecting rod is provided with a limiting groove along the length direction, and the extension plate is provided with a protrusion that matches the limiting groove to limit the moving direction of the connecting rod.

[0009] Optionally, a support pad is fixedly connected to the top of the expansion plate to limit the moving distance of the buffer bucket, and there are multiple support pads.

[0010] Optionally, the blocking mechanism is a guide plate and a replacement plate, and both the guide plate and the replacement plate are detachably arranged on the inner wall of the buffer bucket, the guide plate is inclined, and the replacement plate is in an inverted V shape.

[0011] Optionally, a mounting groove is fixedly connected to the inner wall of the buffer bucket, and the guide plate is slidably connected to the mounting groove.

[0012] Optionally, a mounting seat is fixedly connected to the inner wall of the buffer bucket, and the replacement plate is fixedly connected to the mounting seat by bolts.

[0013] Optionally, the surfaces of the guide plate and the replacement plate are fixedly connected with reinforcing ribs to reduce deformation.

[0014] Optionally, the top of the buffer hopper is connected to an extension portion by bolts, and the cross-section of the extension portion is an inverted trapezoid to reduce the scattering of materials to the outside.

[0015] The utility model provides a shock-resistant metering bin, which has the following beneficial effects:

[0016] The utility model provides an impact-resistant metering bin. Through the coordinated arrangement of the buffer hopper and the blocking mechanism, when ore falls into the hopper, the ore will first collide with the blocking mechanism, thereby reducing the impact of the ore on the hopper and reducing the possibility of deformation of the hopper. At the same time, the blocking mechanism can be quickly replaced, reducing the difficulty of later maintenance. Furthermore, through the buffer mechanism arranged on one side of the buffer hopper, when the ore collides with the blocking mechanism in the buffer hopper, the buffer hopper will push the bottom connecting rod to move downward, thereby driving the connecting plate to move. When the connecting plate moves downward, the external tension spring can play a buffering role, further reducing the impact force between the ore and the device, and reducing the possibility of bulging and deformation of the bottom hopper.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: an impact-resistant metering bin, comprising a hopper 1, a buffer hopper 2 and a buffer mechanism for buffering. A material receiving bin 3 is provided inside the hopper 1, and the buffer hopper 2 is sleeved on the inner wall of the material receiving bin 3.

[0024] The buffer mechanism includes a connecting rod 4, a connecting plate 5 and a tension spring 6. An extension plate 7 is fixedly connected to the outside of the upper surface of the hopper 1. The top of the connecting rod 4 is fixedly connected to the bottom of the buffer hopper 2, and the connecting rod 4 passes through the extension plate 7. The connecting plate 5 is fixedly connected to the bottom of the connecting rod 4. The tension spring 6 is fixedly connected to the middle of the upper surface of the connecting plate 5 and the top is fixedly connected to the bottom of the extension plate 7.

[0025] The buffer bucket 2 can move up and down to a certain extent in the hopper 1. When the ore collides with the buffer bucket 2, the ore will push the buffer bucket 2 down. During the descent of the buffer bucket 2, the connecting rod 4 and the connecting plate 5 fixed on the outside will be driven to move downward. During the downward movement of the connecting plate 5, the tension spring 6 installed above will be stretched, thereby reducing the impact force received by the buffer bucket 2. The ore decelerated by the buffer bucket 2 will fall into the hopper at the bottom. The buffer mechanism reduces the impact of the ore on the bottom of the hopper. The blocking mechanism is provided on the inner wall of the buffer bucket 2 to increase the contact range between the buffer bucket 2 and the ore. The blocking mechanism can block the ore, so that the externally installed buffer mechanism plays a buffering role. Since the ore is granular, after the ore below falls, the tension spring 6 can drive the buffer bucket 2 to reset and continue to play a buffering role for the ore behind.

[0026] In this embodiment, as a preferred solution, a limiting groove 8 is provided on the outer surface of the connecting rod 4 along the length direction, and a protrusion that matches the limiting groove 8 is provided on the expansion plate 7 to limit the moving direction of the connecting rod 4.

[0027] The setting of the limiting groove 8 can limit the moving direction of the connecting rod 4, making it more stable during use and reducing the possibility of the buffer bucket 2 shaking laterally.

[0028] In this embodiment, as a preferred solution, a support pad 9 is fixedly connected to the top of the expansion plate 7 to limit the moving distance of the buffer bucket 2, and there are multiple support pads 9.

[0029] During the downward movement of the buffer plate, the support pad 9 on the top can limit the downward movement distance of the buffer bucket 2 to prevent the buffer bucket 2 from colliding with the expansion plate 7 and causing deformation, thereby improving the service life of the device.

[0030] A blocking mechanism is provided inside the buffer bucket 2 to resist impact.

[0031] In this embodiment, as a preferred solution, the blocking mechanism is a guide plate 10 and a replacement plate 11. Both the guide plate 10 and the replacement plate 11 are detachably arranged on the inner wall of the buffer bucket 2. The guide plate 10 is inclined and the replacement plate 11 is inverted V-shaped. The inner wall of the buffer bucket 2 is fixedly connected with a mounting groove 12. The guide plate 10 is slidably connected to the mounting groove 12. The inner wall of the buffer bucket 2 is fixedly connected with a mounting seat 13. The replacement plate 11 is fixedly connected to the mounting seat 13 by bolts.

[0032] The guide plate 10 and the replacement plate 11 are both arranged in an inclined shape to increase the contact area with the ore without affecting the falling of the ore. The guide plate 10 can be inserted into the mounting groove 12 to fix the position of the guide plate 10. The replacement plate 11 can be fixed on the mounting seat 13. The replacement plate 11 and the guide plate 10 cooperate with each other to make the ore falling from above collide with the blocking mechanism as much as possible to reduce the impact on the bottom of the docking silo 3. The blocking mechanism can be quickly replaced to reduce the difficulty of maintenance.

[0033] In this embodiment, as a preferred solution, the surfaces of the guide plate 10 and the replacement plate 11 are fixedly connected with reinforcing ribs 14 to reduce deformation.

[0034] The reinforcing ribs 14 protrude outwards to improve the overall strength of the guide plate 10 and the replacement plate 11, reduce the possibility of bending, and at the same time guide the ore so that the ore can fall faster.

[0035] In this embodiment, as a preferred solution, the top of the buffer hopper 2 is connected to an extension portion 15 by bolts, and the cross-section of the extension portion 15 is in an inverted trapezoidal shape to reduce the scattering of materials to the outside.

[0036] The extension portion 15 can increase the size of the opening above the buffer hopper 2 so that the ore can fall into the buffer hopper 2 as much as possible, reduce the amount of ore falling outside the device, and improve the utilization rate of the ore.

[0037] A piezoresistive dynamometer is provided inside the hopper 1 to measure the weight of the material in the hopper 1. At the same time, an opening and a baffle adapted to the opening are provided at the bottom to close the hopper 1 and discharge the material in the hopper 1. Since measuring the weight in the metering bin is existing common knowledge, it will not be repeated in this application.

[0038] In the present invention, the working steps of the device are as follows:

[0039] 1. When in use, install the device at the desired location, pour the ore into the buffer hopper 2, and the ore passing through the buffer hopper 2 falls into the receiving bin 3 at the bottom, and is discharged from the bottom of the receiving bin 3 after being measured;

[0040] 2. After using for a period of time, remove the extension part 15, take out the guide plate 10 from the installation groove 12, and remove the replacement plate 11 from the mounting seat 13. After removal, replace the guide plate 10 and the replacement plate 11.
