Description

Technical Field

[0001] The utility model relates to the technical field of bucket wheel stacker reclaimer unloading devices, in particular to a material blocking device for adjusting a coal flow drop point of a chute of a bucket wheel stacker reclaimer. Background Art

[0002] Bucket wheel stacker reclaimer is a kind of equipment widely used in large material yards such as ports, mines, power plants, etc. for efficient and continuous loading, unloading and conveying of bulk materials. Bucket wheel stacker reclaimer has become the most widely used heavy-duty unloading equipment in power plants and ports due to its high recovery rate, convenient operation, simple and flexible operation and easy automation control.

[0003] The unloading device is an important part of the bucket wheel stacker reclaimer. After being unloaded from the unloading device of the bucket wheel stacker reclaimer, various bulk materials are transferred to the system transfer belt to complete the bulk material transfer work. However, after the bulk materials fall from the chute, their coal flow point is fixed and cannot be adjusted. The bulk materials are easy to accumulate on one side of the system transfer belt, causing the system transfer belt to deviate during operation. This situation will not only cause the system transfer belt to scatter materials and reduce the transfer efficiency, but in more serious cases, the belt will scrape the metal structures on both sides, causing the belt to be scratched and torn. Utility Model Content

[0004] In order to solve at least one of the above-mentioned technical problems, the utility model proposes a material blocking device for adjusting the coal flow point of the chute of a bucket wheel stacker and reclaimer, by rotating a material blocking plate for adjusting the coal flow point on the inner walls of both sides of the material guide chute through rotating hinges, and adjusting the angle between the material blocking plate and the material guide chute through an angle adjustment component, thereby achieving adjustment of the coal flow point, and solving the problem that loose coal falling from the chute is easily accumulated on one side of the system transfer belt, causing the belt to deviate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A material blocking device for adjusting the coal flow point of a chute of a bucket wheel stacker and reclaimer comprises a material blocking plate, each of which is rotatably mounted on the inner walls of both sides of a material guide trough by at least one rotating hinge, at least one adjustment hole is provided on both sides of the material guide trough, an angle adjustment component for adjusting the relative rotation angle between the material blocking plate and the material guide trough is rotatably provided in the adjustment hole, and the tail end of the angle adjustment component abuts against the back side of the material blocking plate.

[0007] Preferably, the angle adjustment assembly includes an adjustment nut arranged on the outside of the material guide groove and corresponding to the adjustment hole, and an adjustment bolt adapted to the adjustment nut; the tail end of the adjustment bolt is located on the inside of the material guide groove.

[0008] Preferably, the adjusting nut has a plurality of reinforcing ribs in an annular array around the adjusting nut, which are fixedly connected to the adjusting nut.

[0009] Preferably, a gasket is provided at the upper opening of the adjusting nut away from the material guiding groove to prevent the adjusting bolt from being over-tightened, and a through hole adapted to the adjusting bolt is provided at the center of the gasket.

[0010] Preferably, the tail end of the adjusting bolt is an arc surface.

[0011] Preferably, an angle adjustment pad for increasing the adjustment angle is provided on the back of the baffle plate, and the slope of the angle adjustment pad contacts the tail end of the adjustment bolt.

[0012] Preferably, the cross-section of the angle adjustment pad is L-shaped.

[0013] Preferably, a wear-resistant lining is provided on the front side of the material baffle plate to prevent wear.

[0014] Preferably, the rotating hinge comprises two first hinge ears fixed at intervals on the inner wall of the material guiding trough and a second hinge ear rotatably arranged between the two first hinge ears through a hinge shaft, and the second hinge ear is fixed to the back side of the material baffle plate.

[0015] Preferably, two rotating hinges and two angle adjustment components are spaced apart along the length direction of the material guiding trough.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model realizes the adjustment of the coal flow point by rotating the baffle plates for adjusting the coal flow point on the inner walls of both sides of the guide trough through rotating hinges, and adjusting the angle between the baffle plates and the guide trough through the angle adjustment component, so as to achieve a relatively uniform distribution of the loose coal on the system transfer belt, thereby avoiding the problem of deviation during the operation of the system transfer belt. The device has a simple structure and is easy to adjust. It ensures the safe operation of the system transfer belt and also improves the transfer efficiency of the loose materials to a certain extent.

[0018] By setting the tail end of the adjusting bolt as an arc surface, the contact area between the tail end of the adjusting bolt and the baffle plate is reduced, thereby reducing the resistance between the adjusting bolt and the baffle plate, making the angle adjustment between the baffle plate and the guide trough easier and more labor-saving.

[0019] By arranging a wear-resistant lining plate on the front of the baffle plate, it is prevented that the bulk material impacts the baffle plate for a long time, thereby preventing the baffle plate from being damaged, and the service life of the baffle plate is extended.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention.

[0028] Please refer to Figure 1-6 A material blocking device for adjusting the coal flow point of a chute 8 of a bucket wheel stacker and reclaimer comprises a material blocking plate 2, each of which is rotatably mounted on the inner walls of both sides of a material guide trough 1 through at least one rotating hinge 7, at least one adjusting hole is provided on both sides of the material guide trough 1, and an angle adjusting component 3 for adjusting the relative rotation angle between the material blocking plate 2 and the material guide trough 1 is rotatably provided in the adjusting hole, and the tail end of the angle adjusting component 3 is against the back of the material blocking plate 2.

[0029] In this embodiment, the baffle plate 2 for adjusting the coal flow point is rotated on the inner walls of the two sides of the guide trough 1 by rotating the hinge 7, and the angle between the baffle plate 2 and the guide trough 1 is adjusted by the angle adjustment component 3, so as to adjust the coal flow point, so that the loose coal on the system transfer belt is relatively evenly distributed, thereby avoiding the problem of deviation during the operation of the system transfer belt. The device has a simple structure and is easy to adjust. It ensures the safe operation of the system transfer belt and also improves the transfer efficiency of the loose materials to a certain extent.

[0030] It should be noted that the actual installation position of the baffle plate 2 should be determined according to the flow direction of the coal flow in the chute 8. After installation, according to the actual landing point of the loose coal, the rotation angle between the baffle plate 2 and the guide chute 1 is adjusted through the angle adjustment component 3 to adjust the impact point of the coal flow and the baffle plate 2. The angles of the baffle plates 2 and the guide chute 1 installed on both sides should be adjusted according to the actual transportation needs to adjust the landing point of the loose coal on both sides of the chute 8 that impacts the baffle plate 2, so that it can be scattered as evenly as possible on the system transport belt.

[0031] like Figure 2 As shown, the angle adjustment assembly 3 includes an adjustment nut 31 arranged on the outside of the material guide trough 1 corresponding to the adjustment hole and an adjustment bolt 32 adapted to the adjustment nut 31; the tail end of the adjustment bolt 32 is located on the inside of the material guide trough 1.

[0032] It is understandable that by screwing the adjusting bolt 32 and adjusting the length of the adjusting bolt 32 inside the material guide trough 1 , the material baffle plate 2 is moved away from or close to the inner wall of the material guide trough 1 , thereby adjusting the angle between the material baffle plate 2 and the material guide trough 1 .

[0033] In order to make the adjustable angle range between the baffle plate 2 and the inner wall of the material guide trough 1 larger, in this example, an angle adjustment pad 5 for increasing the adjustment angle is provided on the back of the baffle plate 2, and the slope of the angle adjustment pad 5 contacts the tail end of the adjustment bolt 32.

[0034] It should be noted that the cross section of the angle adjustment pad 5 in this embodiment is L-shaped. Specifically, after the angle adjustment pad 5 is installed, a wedge-shaped surface is formed on the back of the material baffle plate 2. When the adjustment bolt 32 is turned, the tail end of the adjustment bolt 32 slides on the slope of the wedge-shaped surface. Since the wedge-shaped surface has a certain height, this increases the adjustment range of the rotation angle between the material baffle plate 2 and the material guide trough 1 to a certain extent.

[0035] In order to enhance the stability of the installation between the adjusting nut 31 and the outer wall of the guide trough 1, in this embodiment, a plurality of reinforcing ribs 4 are arranged in an annular array around the adjusting nut 31 and are fixedly connected to the adjusting nut 31. The number of reinforcing ribs 4 can be determined according to actual needs.

[0036] In this embodiment, a gasket 33 is provided at the upper opening of the adjusting nut 31 away from the material guide trough 1 to prevent the adjusting bolt 32 from being over-tightened, and a through hole adapted to the adjusting bolt 32 is provided at the center of the gasket 33 .

[0037] like Figure 3As shown, the tail end of the adjusting bolt 32 is an arc surface. Since when adjusting the angle between the baffle plate 2 and the guide groove 1, there is sliding friction between the adjusting bolt 32 and the baffle plate 2, the resistance between the two is relatively large. The tail end of the arc surface can make the contact surface between the tail end of the adjusting bolt 32 and the baffle plate 2 or the angle adjustment pad 5 arranged on the back thereof smaller, so that the friction resistance between the two is relatively small. In this way, the purpose of saving effort when turning the adjusting bolt 32 can be achieved.

[0038] Obviously, in order to save more effort, a ball structure can also be set at the tail end of the adjusting bolt 32 in actual operation, so that rolling contact can be achieved between the adjusting bolt 32 and the baffle plate 2 or the angle adjustment pad 5, which will save more effort than sliding contact.

[0039] like Figure 4 As shown, in this embodiment, two sets of adjusting bolts 32 and adjusting nuts 31 are provided along the length direction of the material guide trough 1 and within the length range corresponding to the material baffle plate 2. Obviously, when the length of the material baffle plate 2 is longer, the number of adjusting bolts 32 and adjusting nuts 31 can be appropriately increased to make the adjustment more convenient and labor-saving. At the same time, the adjusting bolts 32 also play a role in supporting and stabilizing the material baffle plate 2 in the structure of the device. Properly increasing their number can improve the supporting force and stability of the overall structure.

[0040] like Figure 5 As shown, the front of the baffle plate 2 is provided with a wear-resistant lining plate 6 for preventing wear. It is understandable that the impact of the coal flow on the baffle plate 2 can easily damage or deform the baffle plate 2. Providing a layer of wear-resistant lining plate 6 on its surface can reduce the damage to the baffle plate 2 and extend its service life. Of course, the wear-resistant lining plate 6 is preferably set to be replaceable, so that after the wear-resistant lining plate 6 is used for a long time, only the damaged wear-resistant lining plate 6 can be replaced without replacing the baffle plate 2, which can reduce production costs. The fixing method between the wear-resistant lining plate 6 and the baffle plate 2 can be adhesive or bolt fixing.

[0041] In this embodiment, the material blocking plate 2 and the wear-resistant lining plate 6 are both rectangular.

[0042] like Figure 2 , Figure 4 and Figure 6 As shown, the rotating hinge 7 includes two first hinge ears 71 fixed on the inner wall of the material guide trough 1 at intervals and a second hinge ear 73 rotatably arranged between the two first hinge ears 71 through a hinge shaft 72, and the second hinge ear 73 is fixed to the back side of the baffle plate 2.

[0043] It should be noted that in this embodiment, the rotating hinge 7 is arranged on the upper part of the material baffle plate 2. And two rotating hinges 7 are arranged at intervals along the length direction of the material guide trough 1. Obviously, according to the length of the material baffle plate 2, the number of rotating hinges 7 can be appropriately increased to ensure the stability of the rotation of the material baffle plate 2 and the firmness of the connection with the material guide trough 1.

[0044] Other structures related to the bucket wheel stacker and reclaimer in this application are prior art and will not be described in detail in this application.

[0045] The utility model realizes the adjustment of the coal flow point by rotating the baffle plate 2 for adjusting the coal flow point on the inner walls of both sides of the guide trough 1 through the rotating hinge 7, and adjusting the angle between the baffle plate 2 and the guide trough 1 through the angle adjustment component 3, so as to achieve a relatively uniform distribution of the loose coal on the system transfer belt, thereby avoiding the problem of deviation during the operation of the system transfer belt. The device has a simple structure and is easy to adjust. It ensures the safe operation of the system transfer belt and also improves the transfer efficiency of the loose materials to a certain extent.

[0046] The above is a specific implementation of the embodiment of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the scope of protection of this application.
