Description

Technical Field

[0001] The invention relates to the field of coal mining and application, and in particular to a conveying device. Background Art

[0002] At present, the gangue sorting is mainly carried out on the flat belt used to transport the gangue. The actuator grabs and picks out the flat belt or pushes it to both sides of the belt, thereby realizing the sorting of coal and gangue.

[0003] Since some coal mines produce large amounts of gangue, it takes a lot of energy for the actuator to sort it on a flat belt, which places high load requirements on the actuator. In addition, the shape of the gangue is irregular, making it difficult to grab. Another solution is to push the gangue to slide to both sides of the belt, but it is difficult to sort it in time due to the heavy weight and high friction of the gangue, and it may even cause scratches and damage to the belt due to friction.

[0004] For this reason, new improvements are urgently needed to the existing technology. Summary of the invention

[0032] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0033] In order to solve the problem that gangue is difficult to push on the conveying bearing and the belt is damaged due to forced pushing, the present invention designs a new conveying device on which gangue is sorted. Generally, the material maintains balance under the action of gravity, friction and support force; when the material is identified as a sorting target, the sorting mechanism only needs to push and destroy the force balance to achieve gangue sorting. The specific scheme is as follows:

[0034] See also Figure 1 and Figure 2The conveying device provided in this embodiment is used for conveying and sorting materials, and includes a driving component (not shown), a bracket 10, a plurality of rolling components 20 arranged on the bracket 10, and a conveying carrier 30 laid on the plurality of rolling components 20; the plurality of rolling components 20 are used to support the conveying carrier 30, preferably, each of the rolling components 20 can rotate on the bracket 10; the driving component is connected to the conveying carrier 30 to drive the conveying carrier 30 to rotate; the cross-sectional shape of the conveying part of the conveying carrier 30 (the conveying part: the part that can carry materials, that is, the part of the conveying carrier 30 located on the upper side) is generally high in the middle and low on both sides. Through the above scheme, in the process of conveying materials, the materials are sorted in the conveying part of the conveying carrier 30. Since the cross-sectional shape of the conveying part of the conveying carrier 30 is high in the middle and low on both sides, the materials are more likely to slide off the conveying carrier 30, and the mechanical arm performing the sorting can easily push the impurities in the materials off the conveying carrier 30 or grab them from the conveying carrier 30 to the collection frame (the collection frame is used to collect the impurities in the materials) with a small force. On the other hand, the friction between the impurities and the transport support 30 is also reduced, thereby reducing the wear on the transport support 30.

[0035] The driving component may be a servo motor, whose output shaft is connected to a roller, which directly cooperates with the conveying carrier 30, so that the conveying carrier 30 can continuously roll and convey materials under the drive of the servo motor. The conveying carrier 30 may be a conveyor belt, a conveyor chain, etc.

[0036] It should be noted that Figure 1 The part shown in the figure is a part of the conveying device, which is only for illustration and does not fully represent the complete conveying device. The actual conveying carrier 30 is closed. Figure 1 Only the conveying part on the upper side of the conveying carrier 30 is shown, and other parts of the conveying carrier 30 and the driving components are not shown. Since these parts are not improved parts of this solution, the relevant structures are not shown and are not introduced in detail. The technology in this field can be implemented according to the existing technology.

[0037] In this embodiment, the transported material is coal mixed with gangue, and the sorting mechanism needs to sort the gangue out of the coal. The coal mixed with gangue is transported on the transport carrier 30, and the coal mixed with gangue has a tendency to roll down on the protruding transport carrier 30, but is kept on the transport carrier 30 under the action of friction, and the sorting mechanism grabs or pushes down the gangue.

[0038] Generally, the material maintains balance on the conveying support 30 under the action of gravity, friction and supporting force; when the material is identified as a sorting target, the sorting mechanism only needs to push and destroy the force balance to push the coal gangue from the material into the collection frame to achieve gangue sorting.

[0039] Of course, the transported materials are not limited to coal mixed with gangue. All materials that need to be sorted can be transported using this type of transport device, and it is particularly suitable for the knock-off sorting method (the knock-off sorting method refers to the use of external force to knock the sorted objects on the conveying carrier off the conveying carrier, and a container can be set at the knock-off position to collect them).

[0040] In some specific embodiments, the cross-section of the conveying portion of the conveying carrier 30 is in the shape of an upwardly convex arc, as shown in FIG. Figure 3 Of course, other shapes with convex structures are also possible, for example, the cross-section of the conveying part of the conveying carrier 30 is in the shape of a roof with a certain slope.

[0041] For the curvature of the arc, to ensure the stable transportation of the material on the conveying carrier 30, refer to Figure 3 , the angle between the tangent line at the edge of the arc and the horizontal plane is 0°<β≤30°. Preferably, 10°<β≤30°. Within this angle range, the coal can be transported more stably on the conveying support 30. The larger the value of β, the easier it is for the gangue to be pushed off the conveying support 30. Of course, the coal on the conveying support 30 is more unstable. Specifically, the value of β can be 15°, 20°, 25°, etc.

[0042] In some specific embodiments, the support 10 includes a plurality of columns of support pillars 11 arranged along the width direction of the conveying carrier 30, each rolling component 20 is respectively disposed on two adjacent support pillars 11, and the height of the support pillar 11 near the middle is higher than the height of the support pillar 11 near the edge, so that the middle rolling component 20 is located higher. Figure 1-2 As shown, the support columns 11 on the bracket 10 are divided into 4 columns, with 15 columns in each column. The length of each column is designed according to the required length of the conveying part of the conveying carrier 30. The longer the conveying part, the more support columns 11 there are in each column.

[0043] Combined with reference Figure 1-3The center of the rolling component 20 is provided with a center hole, and a roller 21 is passed through the center of the rolling component 20. One end of the roller 21 is arranged on a support column 11, and the other end is arranged on a support column 11 in another adjacent row. The rolling component 20 can rotate around the roller 21. Correspondingly, an axial hole is also provided on the support column 11 for matching with the roller 21. The axial hole on the support column 11 and the roller 21 are interference fit, and the two cannot rotate relative to each other after matching. The center hole of the rolling component 20 and the roller 21 are clearance fit, and can rotate relative to each other after matching.

[0044] In another embodiment, see Figure 4 , protruding shaft ends 22 are formed at both ends of the rolling component 20, and the shaft ends 22 are part of the rolling component 20, and the two are integrally formed. A bearing is provided on each support column 11, and the two shaft ends 22 of each rolling component 20 are provided on the support column 11 through the bearings on the corresponding support column 11. With this structure, the processing of the rolling component 20 can be made easier, and the bearings are standard parts, cheap and have good rolling effect.

[0045] The width and number of rows of rolling components 20 can be set according to the width of the conveying carrier 30. In some embodiments: a number of rolling components 20 are distributed in an odd number of rows along the width direction of the conveying carrier 30, and are symmetrically distributed about the center line of the conveying carrier 30; the axis of the middle row of rolling components 20 is horizontally set, and the shape of the middle row of rolling components 20 is drum-shaped; the axis of at least one row of rolling components 20 on both sides is tilted downward from the middle of the conveying carrier 30 to the edge, and the shape of at least one row of rolling components 20 on both sides is cylindrical or drum-shaped. Figure 3 As shown, the rolling components 20 are distributed in three rows along the width direction of the conveying carrier 30; the axis of the rolling components 20 in the middle row is horizontally arranged, and the axis of the rolling components 20 in the two rows on both sides are inclined downward; the shape of the rolling components 20 in all rows is drum-shaped.

[0046] In other embodiments, a plurality of the rolling components 20 are distributed in an even number of rows along the width direction of the conveying carrier 30, and are symmetrically distributed about the center line of the conveying carrier 30; the axis of each row of rolling components 20 is inclined downward from the center line position of the conveying carrier 30 to both sides; the shape of the rolling components 20 in the middle two rows is drum-shaped, and the shape of the rolling components 20 in the remaining rows is cylindrical or drum-shaped.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
