Description

Technical Field

[0001] The invention relates to the technical field of coal hoppers, in particular to a reinforced steel coal hopper. Background Art

[0002] A coal hopper usually refers to a container used to store and transport coal. It is widely used in industry and energy. Its main function is to receive coal delivered by conveying equipment such as belt conveyors, bucket elevators, etc., and provide a stable supply of coal for boilers or other combustion equipment. Coal hoppers are generally made of metal materials such as steel, and can be round or square in shape. The design takes into account factors such as load-bearing, wear resistance and corrosion resistance. During use, the capacity and structural design of the coal hopper directly affect the transportation efficiency and storage capacity of coal. Therefore, reasonable design and calculation are required when planning the coal hopper.

[0003] In order to increase the strength of the existing coal hopper, the wall thickness of the coal hopper is usually increased. Some coal hoppers also use a connecting structure to increase the strength of the coal hopper. For example, Chinese patent announcement No. CN213801157U discloses "a reinforced steel coal hopper", which is provided with an inner connecting plate on the wall plate of the coal hopper body, and a plurality of tie rods are provided on the inner connecting plate. The tie rods are used to connect the two end wall plates of the coal hopper body, while ensuring the strength of the steel coal hopper, the total weight of the steel coal hopper is reduced, thereby reducing the cost of the steel coal hopper. The tie rod is a hollow tubular structure, and the two ends of the tie rod are provided with threads. The two ends of the tie rod are threadedly connected with screw rods, one end of the screw rod is hinged to the hinge support, and the tie rod is provided with an adjustment hole. When the wall plate of the steel coal hopper is deformed, a rod-shaped tool such as a screwdriver is inserted into the adjustment hole and the tie rod is rotated to adjust the overall assembly length of the tie rod and the screw rod to compensate for the deformation of the wall plate, thereby ensuring the strength and rigidity of the steel coal hopper.

[0004] However, in actual use, the connecting rod in the coal hopper not only easily causes coal blockage, but also requires alternating additions to the spaces on both sides of the pull rod when filling the coal hopper to prevent coal from accumulating in only one side of the space and reducing the capacity of the coal hopper. This not only increases the difficulty of operation, but also affects the efficiency of filling. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the connecting rod in the coal hopper easily causes coal blockage, and when filling the coal hopper, it is necessary to fill the space on both sides of the pull rod alternately, which increases the difficulty of operation and affects the filling efficiency. A reinforced steel coal hopper is proposed.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-5 A reinforced steel coal hopper comprises a hopper body 1 and a supporting structure 2, wherein the supporting structure 2 comprises a bracket 21 and a connecting plate 22, a buffer structure 3 is arranged between the connecting plate 22 and the bracket 21, and a mounting plate 4 is fixedly connected to the outer wall of the hopper body 1, and the mounting plate 4 is connected to the connecting plate 22 by bolts;

[0029] A shield 5 is provided on the connecting plate 22, and an opening 51 for convenient feeding is provided on one side of the shield 5. A reinforcing plate 6 is provided in the hopper body 1, and an extension part 52 is fixedly provided on the outer wall of the shield 5, and the extension part 52 corresponds to the bolt.

[0030] In the present invention, the side of the hopper body 1 that collides severely with coal during loading is reinforced by a reinforcing plate 6 to reduce damage to the coal hopper, and a buffer structure 3 is provided to absorb the impact on the entire hopper body 1 during filling, thereby reducing damage to the coal hopper and extending the service life of the coal hopper.

[0031] Furthermore, in this embodiment, an arc portion 61 is provided at the upper end of the reinforcing plate 6, a plug plate 62 is fixedly provided at the lower end of the arc portion 61, and a connecting frame 63 corresponding to the plug plate 62 is fixedly provided on the hopper body 1. When the reinforcing plate 6 is severely worn due to long-term use, it can be taken out and replaced. The arc portion 61 has a certain deformation ability, and can deform to absorb part of the impact when the reinforcing plate 6 is hit by coal.

[0032] In this embodiment, an elastic buffer 64 is fixedly provided on the inner wall of the reinforcing plate 6, and the other end of the buffer 64 abuts against the hopper body 1. When the reinforcing plate 6 is impacted by the coal, the buffer 64 is squeezed to cause elastic deformation, thereby buffering and partially absorbing the impact on the reinforcing plate 6, thereby reducing the impact on the reinforcing plate 6.

[0033] Furthermore, in the present embodiment, a limiting structure 7 cooperating with the plug plate 62 is provided on the connecting plate 22, and the limiting structure 7 includes a limiting plate 71 movably plugged with the connecting plate 22, one end of the limiting plate 71 is movably plugged with the plug plate 62, and the other end of the limiting plate 71 is fixedly connected with a baffle 72, and the reinforcing plate 6 is fixed by the limiting structure 7 to prevent the reinforcing plate from falling off during use.

[0034] In this embodiment, a connecting hole is opened on the connecting plate 22, and a limiting groove corresponding to the connecting hole is set on the limiting plate 71. A limiting column 73 is movably inserted in the connecting hole, and the limiting column 73 is clamped in the limiting groove. The limiting column 73 is clamped in the limiting groove to limit the movement of the limiting plate 71, thereby preventing the limiting plate 71 from separating from the inserting plate 62, and further preventing the reinforcing plate 6 from falling off.

[0035] It should be noted that, in the present embodiment, an avoidance groove 74 cooperating with the limit plate 71 is provided on the limit column 73, and a support spring 75 is provided between the limit column 73 and the connecting hole. During daily use, the support spring 75 supports the limit column 73 so that its upper end part extends out of the connecting hole. At this time, the avoidance groove 74 is separated and misaligned from the limit plate 71, so that the limit plate 71 is fixed. By pressing down the limit column 73, the avoidance groove 74 is made to correspond to the limit plate 71, so that the limit plate 71 can be moved along the avoidance groove 74, so that the reinforcing plate 6 can be removed for replacement.

[0036] In addition, in the present embodiment, the buffer structure 3 includes a buffer spring 31 and a positioning column 32. The positioning column 32 is fixedly connected to the connecting plate 22. The positioning column 32 passes through the mounting plate 4 and the bracket 21 and is movably connected to the bracket 21. The buffer spring 31 is used to buffer and partially absorb the impact on the hopper body 1, thereby reducing the damage to the hopper body 1. The positioning column 32 is provided to prevent the hopper body 1 from being damaged due to shaking and colliding with the bracket 21.

[0037] In this embodiment, the buffer spring 31 is arranged between the connecting plate 22 and the bracket 21. The outer wall of the connecting plate 22 is fixedly provided with a shield 23 that matches the buffer structure 3. The shield 23 prevents coal from falling into the buffer structure 3 and affecting the buffer structure 3.

[0038] In detail, in this embodiment, a reinforcement frame 11 is provided on the hopper body 1, and the reinforcement frame 11 is fixedly connected to the hopper body 1 by bolts. A vibration motor 12 is provided on the outer wall of the hopper body 1. The vibration motor 12 is provided to drive the hopper body 1 to vibrate to prevent internal coal from being blocked, and the reinforcement frame 11 is provided to prevent the hopper body 1 from being deformed.

[0039] In some embodiments, a screen grate 53 is provided on the shield 5. The screen grate 53 is an inclined structure and is connected to the opening 51. The screen grate 53 screens and discharges a large volume of coal to prevent the hopper body 1 from being damaged and to prevent the coal hopper from being blocked.

[0040] Working mode: When the coal hopper is filled with materials, most of the coal collides with the reinforcing plate 6, reducing the damage to the hopper body 1. When the reinforcing plate 6 is impacted by the coal, the buffer 64 is squeezed to make it elastically deformed, thereby buffering and partially absorbing the impact on the reinforcing plate 6. The arc portion 61 deforms to absorb part of the impact, reducing the damage to the reinforcing plate 6. By pressing down the limit column 73, the avoidance groove 74 corresponds to the limit plate 71, so that the limit plate 71 can move along the avoidance groove 74 and separate from the plug plate 62, so that the reinforcing plate 6 can be removed for replacement.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
