Description

Technical Field

[0001] The utility model relates to the technical field of bunker cleaning machines, in particular to an aggregate conveying mechanism of a mine bunker cleaning machine. Background Art

[0002] The mine bunker cleaning machine is mainly used for dredging the mine bottom sump and sedimentation tank.

[0003] Generally, the amount of water in the mine bottom sump is huge, and the sedimentation tank is often hundreds of meters long. In the prior art, the mine bunker cleaning machine conveys the sump sludge through a feeding trough and a baffle rotating directionally in the feeding trough. The feeding trough is a straight extension structure, usually at an angle of about 40° with the horizontal plane to maintain a relatively high feeding efficiency. The rotating direction of the baffle in the feeding trough is parallel to the feeding trough. However, during the process of conveying the sump sludge, the baffle often carries a lot of moisture. When the conveyed material enters the turntable and trough assembly, it often splashes and pollutes the surrounding equipment, bringing great trouble to the regular maintenance of the mine bunker cleaning machine, such as long maintenance time and high cost. Summary of the Utility Model

[0004] An embodiment of the present application provides an aggregate conveying mechanism of a mine bunker cleaning machine, which can, while ensuring a certain conveying efficiency and keeping the material concentration within a set range, also unload a part of the moisture additionally through a buffer section to reduce the amount of splashing and pollution of the surrounding equipment when the material is conveyed to the turntable and trough assembly, so as to facilitate the regular maintenance of the mine bunker cleaning machine, reduce the workload, reduce the maintenance time, and lower the maintenance cost.

[0005] An embodiment of the present application provides an aggregate conveying mechanism of a mine bunker cleaning machine for directionally conveying the material collected in the aggregate device to the turntable and trough assembly of the bunker cleaning machine. The aggregate conveying mechanism of the mine bunker cleaning machine includes a feeding trough and a conveying chain located in the feeding trough and rotating directionally between the aggregate device and the turntable and trough assembly. The conveying chain is evenly provided with baffles perpendicular to the bottom of the feeding trough and maintaining a predetermined gap with the bottom of the feeding trough. The feeding trough includes a feeding section and a buffer section connected in sequence. The feeding section is close to the aggregate device, and the angle between the feeding section and the horizontal plane is 35° - 45°. The angle between the buffer section and the horizontal plane is 26° - 34°.

[0006] In a possible implementation manner, the angle between the feeding section and the horizontal plane is 41°, and the angle between the buffer section and the horizontal plane is 31°.

[0007] In a possible implementation manner, the length of the buffer section accounts for 1 / 3 - 1 / 2 of the total length of the feeding trough.

[0008] In a possible implementation, the emptying machine further has a driving oil cylinder for driving the material conveying trough. The driving oil cylinder is close to the lower part of the material conveying trough. The telescopic shaft of the driving oil cylinder is connected to the bottom of the material conveying trough and close to the middle of the material conveying trough. An ear seat for connecting the telescopic shaft is arranged at the bottom of the material conveying trough, and the feeding section and the buffer section are demarcated by the ear seat.

[0009] In a possible implementation, a transition section is arranged between the feeding section and the buffer section. The included angle between the transition section and the horizontal plane is between the included angles between the feeding section and the buffer section and the horizontal plane. And the length of the transition section accounts for 8% - 10% of the total length of the material conveying trough. The ear seat is installed on the transition section.

[0010] In a possible implementation, the ear seat includes a seat body with a trapezoidal cross-section. The large end of the seat body is connected to the transition section, and a connection hole for connecting the telescopic shaft through a pin shaft is arranged at the small end of the seat body.

[0011] Beneficial effects: Compared with the prior art, the aggregate conveying mechanism of the mine emptying machine provided by this application realizes the rapid conveying of materials by setting the material conveying trough as a feeding section and a buffer section, where the included angle between the feeding section and the horizontal plane is 35° - 45°, so as to ensure the working efficiency. The included angle between the buffer section and the horizontal plane is 26° - 34°, which can ensure that the material concentration is within the set range by slightly reducing the material conveying efficiency, and at the same time can also buffer the materials, so that the materials will not splash onto the surrounding equipment too much when entering the turntable and the trough assembly, thereby greatly reducing the amount of splash pollution, facilitating the later maintenance of the mine emptying machine, reducing the maintenance workload and working time, and thus reducing the maintenance cost;

[0012] Wherein the feeding section and the buffer section are demarcated by the point where the telescopic shaft of the driving oil cylinder is connected. The driving oil cylinder can bear more force, the working stability of the material conveying trough is better, and the service life is long;

[0013] Wherein a transition section is also arranged between the feeding section and the buffer section, which can play a role in transitioning between rapid feeding and buffering materials, and the material conveying is more stable.

[0014] These and other objects, features and advantages of the present utility model are fully embodied through the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

The basic principles defined in the following description of the present utility model can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present utility model.

[0017] Those skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationship indicated by terms such as "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0018] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple.

[0019] Reference Figure 1, an embodiment of the present application provides an aggregate conveying mechanism for a mine clearing machine, which is used to directionally convey the materials collected in the aggregate device 10 to the turntable and trough assembly 20 of the clearing machine. Specifically, the aggregate conveying mechanism of the mine clearing machine includes a feeding trough 30 and a conveying chain 40 located in the feeding trough 30 and rotating directionally between the aggregate device 10 and the turntable and trough assembly 20. Among them, baffle plates 41 are evenly distributed on the conveying chain 40, and the baffle plates 41 are perpendicular to the bottom of the feeding trough 30 and maintain a predetermined gap with the bottom of the feeding trough 30, so that when the conveying chain 40 drives the baffle plates 41 to rotate directionally, the materials can be directionally conveyed in the feeding trough 30, realizing the conveying of water-containing coal slime at the bottom of the mine. The key lies in that the feeding trough 30 includes a feeding section 31 and a buffer section 33 connected in sequence. Among them, the feeding section 31 is close to the aggregate device 10. Correspondingly, the buffer section 33 is close to the turntable and trough assembly 20. In addition, the included angle α between the feeding section 31 and the horizontal plane is 35° to 45°, so that the rapid conveying of materials can be realized through the feeding section 31 with a larger included angle. At the same time, the included angle β between the buffer section 33 and the horizontal plane is 26° to 34°, so that more moisture can be unloaded through the buffer section 33 with a smaller included angle and the material concentration can be ensured to be within the set concentration range. Furthermore, when the materials pass through the buffer section 33 and run to the turntable and trough assembly 20, the splashing pollution of the surrounding equipment can be greatly reduced or even completely avoided, which is convenient for the later maintenance of the mine clearing machine, reduces the workload and working time of maintenance, and thus can reduce the maintenance cost.

[0020] In one embodiment, the included angle between the feeding section 31 and the horizontal plane is 41°, and at the same time, the included angle between the buffer section 33 and the horizontal plane is 31°.

[0021] In one embodiment, the length of the buffer section 33 accounts for 1 / 3 to 1 / 2 of the total length of the feeding trough 30. Thus, it can not only ensure that the feeding section 31 has enough length to realize the rapid conveying of materials, that is, ensure the working efficiency, but also does not affect the buffering of the buffer section 33 on the materials, and reduces or even avoids splashing pollution of the equipment around the turntable and trough assembly 20 by unloading a part of the moisture.

[0022] In one embodiment, the emptying machine further has a driving oil cylinder 50 for driving the material conveying trough 30. The driving oil cylinder 50 is close to the lower part of the material conveying trough 30. At the same time, the telescopic shaft 51 of the driving oil cylinder 50 is connected to the bottom of the material conveying trough 30 and is close to the middle part of the material conveying trough 30. In addition, an ear seat 34 for connecting the telescopic shaft 51 is arranged at the bottom of the material conveying trough 30, and the feeding section 31 and the buffer section 33 take the ear seat 34 as the demarcation point. In this way, the position at the demarcation point with a relatively large force intensity can be directly set on the supporting point position of the driving oil cylinder 50, enabling the driving oil cylinder 50 to directly share more force, making the material conveying trough 30 work more stably and having a longer service life.

[0023] Further preferably, a transition section 32 is arranged between the feeding section 31 and the buffer section 33. At the same time, the included angle between the transition section 32 and the horizontal plane is between the included angles between the feeding section 31 and the buffer section 33 and the horizontal plane, and the length of the transition section 32 accounts for 8% - 10% of the total length of the material conveying trough 30. Thus, the transition section 30 can play a good transition role between quickly conveying materials and buffer-conveying materials, making the material conveying more stable. The ear seat 34 is installed on the transition section 32.

[0024] It should be noted that the transition section 32 should not be too long, as it will affect the effects of the feeding section 31 and the buffer section 33. At the same time, it should not be too short either, as it will affect its own transition effect and is also not convenient for the installation of the ear seat 34.

[0025] Further preferably, the ear seat 34 includes a seat body 341 with a trapezoidal cross-section. The large end of the seat body 341 is connected to the transition section 32. In this way, the connection strength between the seat body 341 and the transition section 32 can be enhanced by increasing the contact area between them, making the connection relationship between the material conveying trough 30 and the driving oil cylinder 50 more stable. In addition, a connection hole for connecting the telescopic shaft 51 through a pin shaft 52 is arranged at the small end of the seat body 341 to facilitate the quick connection with the driving oil cylinder 50.

[0026] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
