Description

Technical Field

[0001] The present invention relates to the technical field of coal mine conveying, and specifically relates to a coal mine conveying device. Background Art

[0002] Coal mine conveying equipment is an essential key equipment in coal mine production, mainly used for continuous transportation and lifting of coal. Its design and selection need to comprehensively consider factors such as underground environment, safety requirements, transportation efficiency, and maintenance cost. Usually, when the conveying height difference is relatively low, the belt conveyor can be used. However, for material conveying at some production sites with a relatively large height difference, a scraper conveyor needs to be used for conveying treatment.

[0003] When the scraper conveyor is in use, the scraper needs to be driven along the guide plate by a chain, which requires driving the chain. However, at the construction site of a coal mine, the working condition environment is relatively poor, and dust will affect the normal operation of the chain. The maintenance cost of the chain is relatively high, and the chain needs to be cleaned frequently. Therefore, it needs to be improved. Summary of the Invention

The other end of the deflection connecting plate is rotatably connected to the end of a second deflection rod. The middle of the second deflection rod is fixedly connected with a triangular scraper. Adjacent two triangular scrapers move synchronously and in opposite directions. The cross-section of the triangular scraper is a right triangle. One right side of the triangular scraper is arranged close to the bottom of the guide platform, and the other right side of the triangular scraper faces away from the ground. After adjacent two triangular scrapers move closer to each other, one right side of one triangular scraper slides along the hypotenuse of the other triangular scraper.

[0007] As a preferred technical solution of the present invention, the cross-section of the material guiding platform is a U-shaped structure, and screening holes are evenly distributed on the bottom of the material guiding platform.

[0008] As a preferred technical solution of the present invention, a spacing adjustment component is provided on the placing base, and a transverse base is provided at the protruding end of the spacing adjustment component, the end of the transverse base is rotatably connected to one end of the diagonal support column, and the other end of the diagonal support column is rotatably connected to the protruding rotating seat.

The entire conveying equipment only needs to set a drive unit at the end of the guide table to control the movement of all triangular scrapers. The structure is simple and will not affect the normal operation due to harsh environment such as dust. The stability and reliability are better. When the mineral material is transferred on the triangular scraper, it will collide and break, and the soil particles attached to the surface will fall through the screening holes, thereby realizing the preliminary screening and crushing of the mineral material and improving work efficiency.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] In one embodiment, please refer to Figures 1 - 11 , a coal mine conveying device, including a placing base 1, a feeding table 2 is arranged on the placing base 1. The placing base 1 is a flat plate structure and can be directly placed on the ground. Through the placing base 1, the entire conveying device is directly placed on the ground. And to improve stability, the placing base 1 can also be fixed to the ground by means of bolt connection. The feeding table 2 is arranged obliquely upward to the right above the placing base 1, and also includes a scraping mechanism 3 and an inclined support mechanism 4; The inclined support mechanism 4 is used to adjust the inclination angle of the feeding table 2, including extended rotating seats 5 arranged at both ends of the feeding table 2. The extended rotating seats 5 face forward and backward and are arranged at the left and right ends of the front and rear two sides of the feeding table 2. On the front and rear sides of the left end of the upper surface of the placing base 1, vertical columns 9 are vertically arranged. The upper ends of the vertical columns 9 are rotatably connected to the extended rotating seats 5 at the left end of the feeding table 2, so that the feeding table 2 can perform pitching deflection along the upper ends of the vertical columns 9 through the extended rotating seats 5; The scraper mechanism 3 includes a guide slide bar 19 arranged on the side of the material guide platform 2, the guide slide bar 19 is arranged parallel to the material guide platform 2, and the two material guide platforms 2 are respectively arranged on the front and rear sides of the material guide platform 2, and extended side plates 18 fixedly connected to the side of the material guide platform 2 are arranged at the left and right ends of the guide slide bar 19, and a sliding suspension block 20 arranged vertically to the material guide platform 2 is slidably connected to the guide slide bar 19, and the upper end of the sliding suspension block 20 is rotatably connected to a first deflection rod 28 arranged in a front-to-back direction, and the end of the first deflection rod 28 close to the center of the material guide platform 2 is fixedly connected to the left end of a deflection connecting plate 29 arranged in a left-to-right direction, and the right end of the deflection connecting plate 29 is rotatably connected to the end of a second deflection rod 30 arranged in a front-to-back direction, and the middle part of the second deflection rod 30 is fixedly connected to a triangular scraper 21, and the two adjacent deflection connecting plates 29 on the left and right are staggered in the front and back direction. The two deflection connecting plates 29 are arranged so that when the left and right sliding suspension blocks 20 move toward each other, there will be no interference problem between the two deflection connecting plates 29. The cross-section of the triangular scraper 21 is a right triangle. The two right-angled sides of the triangular scraper 21 are respectively arranged on the lower side and the right side. When the two triangular scrapers 21 are separated, the right-angled sides below the two triangular scrapers 21 can fall on the upper surface of the material guide platform 2. For example, when the left triangular scraper 21 moves to the right and the right triangular scraper 21 moves to the left, the bottom edge of the left triangular scraper 21 will slide to the inclined surface of the right triangular scraper 21, and the left triangular scraper 21 will move to the upper right along the inclined surface of the right triangular scraper 21, so that the ore is pushed from the left side of the right triangular scraper 21 to the right side of the right triangular scraper 21 through the left triangular scraper 21, thereby realizing the transfer and processing of the ore.

[0025] In one case of this embodiment, the triangular scraper 21 slides alternately with the two adjacent triangular scrapers 21 on the left and right sides, and a cross push-pull assembly 22 for driving the triangular scraper 21 to move horizontally is provided at the end of the material guide platform 2. The cross push-pull assembly 22 includes a cross bar 23 provided at one end of the sliding suspension block 20 close to the ground and parallel to the material guide platform 2, and two parallel push-pull plates 24 are provided on the side of the material guide platform 2 close to the ground, and two adjacent cross bars 23 are fixedly connected to the two push-pull plates 24. For example, according to the attached Figure 7As shown, 14 triangular scraping plates 21 are provided on the material guiding table 2 (14 is just the quantity for easy viewing, and the quantity of the triangular scraping plates 21 only needs to be greater than or equal to two to complete the simple conveying and handling work). That is, 14 triangular scraping plates 21 are provided on one side of the material guiding table 2. Counting from left to right, the odd-numbered sliding suspension blocks 20 are shorter than the even-numbered sliding suspension blocks 20. At this time, the cross bar 23 fixedly connected to the lower end of the odd-numbered sliding suspension block 20 is higher than the cross bar 23 fixedly connected to the lower end of the even-numbered sliding suspension block 20. A push-pull plate 24 arranged in the left-right direction is fixedly connected to the cross bar 23 corresponding to the odd-numbered sliding suspension block 20, and a push-pull plate 24 arranged in the left-right direction is fixedly connected to the cross bar 23 corresponding to the even-numbered sliding suspension block 20. The upper and lower push-pull plates 24 are arranged parallel to each other and move in opposite directions. For example, when the upper push-pull plate 24 moves to the right, the odd-numbered sliding suspension block 20 moves to the right, the odd-numbered triangular scraping plates 21 move to the right, the lower push-pull plate 24 moves to the left, the even-numbered sliding suspension block 20 moves to the left, and the even-numbered triangular scraping plates 21 move to the left. The deflection connecting plate 29 rotates adaptively. Therefore, the odd-numbered triangular scraping plates 21 move obliquely upward to the right along the inclined surface of the even-numbered triangular scraping plates 21. If the situation is reversed, when the upper push-pull plate 24 moves to the left and the lower push-pull plate 24 moves to the right, the even-numbered triangular scraping plates 21 move obliquely upward to the right along the inclined surface of the odd-numbered triangular scraping plates 21 from left to right, thereby intermittently moving the ore on the material guiding table 2 obliquely upward to the right to achieve the effect of material conveying.

[0026] In one case of this embodiment, suspension plates 37 are vertically provided on the front and rear sides at the left end of the lower surface of the material guiding table 2. A rotating column 25 arranged in the front-rear direction is rotatably connected to the middle of the suspension plate 37. The middle of the rotating column 25 is fixedly connected to the middle of a deflection plate 26. The upper end of the deflection plate 26 is rotatably connected to the left end of the upper connecting rod 27. The right end of the upper connecting rod 27 is rotatably connected to the left end of the upper push-pull plate 24. The lower end of the deflection plate 26 is rotatably connected to the left end of the lower connecting rod 27. The right end of the lower connecting rod 27 is rotatably connected to the left end of the lower push-pull plate 24. Therefore, when the deflection plate 26 swings left and right, the deflection plate 26 pulls the upper and lower push-pull plates 24 to move left and right in opposite directions through the connecting rods 27. A main shaft 32 arranged in the front-rear direction is rotatably connected to the lower end of the front suspension plate 37. A deflection driving motor 31 is provided at the rear side of the suspension plate 37. The output shaft of the deflection driving motor 31 is fixedly connected to the rear end of the main shaft 32. One end of a deflection beam 33 is fixedly connected to the front end of the main shaft 32. The other end of the deflection beam 33 is rotatably connected to the lower end of a sliding strip 34. A rotating head 35 is fixedly connected to the front end of the rotating column 25. A sliding groove 36 is provided on the front side of the rotating head 35. The upper part of the sliding strip 34 is slidably connected to the sliding groove 36. Therefore, when the deflection driving motor 31 drives the deflection beam 33 to rotate around the main shaft 32, the main shaft 32 makes the rotating head 35 deflect left and right through the sliding strip 34, thereby making the deflection beam 33 swing left and right.

[0027] In one case of this embodiment, the cross-section of the material guiding table 2 is a U-shaped structure, and screening holes 17 are evenly distributed at the bottom of the material guiding table 2. By designing the material guiding table 2 into a structure with a U-shaped cross-section, retaining edges are formed on the front and rear sides of the material guiding table 2. When the ore moves along the material guiding table 2, the retaining edges on the front and rear sides can prevent the ore from falling. Moreover, screening holes 17 are arranged in the middle of the upper surface of the material guiding table 2, so that during the rolling process of the ore, some fine granular soil blocks can fall and pass through the screening holes 17 to fall to the ground, thus realizing the preliminary screening of the ore.

[0028] In one case of this embodiment, a spacing adjusting assembly 6 is arranged on the placing base 1. A transverse moving base 7 is arranged at the extending end of the spacing adjusting assembly 6. One end of an inclined support column 8 is rotatably connected to the end of the transverse moving base 7, and the other end of the inclined support column 8 is rotatably connected to the extending rotating seat 5. The spacing adjusting assembly 6 includes a first fixing block 14 arranged at the end of the placing base 1. An extending sliding column 15 is slidably connected to the first fixing block 14. A second fixing block 16 is fixedly connected to the end of the extending sliding column 15 away from the placing base 1, and the second fixing block 16 is fixedly connected to the transverse moving base 7. A bearing seat 11 is arranged in the middle of the placing base 1. A push-pull screw rod 13 is rotatably connected to the bearing seat 11. A push plate 12 fixedly connected to the extending sliding column 15 is threadedly connected to the middle of the push-pull screw rod 13. A push-pull motor 10 is arranged in the middle of the placing base 1, and the output shaft of the push-pull motor 10 is fixedly connected to the end of the push-pull screw rod 13. The transverse moving base 7 is arranged on the right side of the placing base 1 in the front-rear direction. The lower ends of the inclined support columns 8 are rotatably connected to the front and rear ends of the upper surface of the transverse moving base 7. The inclined support columns 8 are inclined upward to the right. The upper ends of the inclined support columns 8 are rotatably connected to the extending rotating seat 5 on the right side. The spacing adjusting assembly 6 adjusts the spacing between the transverse moving base 7 and the placing base 1, that is, adjusts the inclination angle of the inclined support column 8, thereby adjusting the inclination angle of the material guiding table 2. The push-pull screw rod 13 is arranged on the middle of the upper surface of the placing base 1 in the left-right direction. The middle of the push-pull screw rod 13 is threadedly connected to the middle of the push plate 12 arranged in the front-rear direction. The front and rear ends of the push plate 12 are fixedly connected to the left end of the extending sliding column 15 arranged in the left-right direction. The middle of the extending sliding column 15 is slidably connected to the first fixing block 14, and the first fixing block 14 is fixed on the front and rear sides of the right end of the upper surface of the placing base 1. Therefore, the push-pull motor 10 drives the push-pull screw rod 13 to rotate, the push-pull screw rod 13 drives the push plate 12 to move left and right, and the push plate 12 makes the transverse moving base 7 move left and right through the extending sliding column 15, finally realizing the adjustment of the pitching angle of the material guiding table 2.

[0029] During the implementation of this embodiment, the placing base 1 is stably placed on the ground, and the push-pull motor 10 is first started, so that the transverse base 7 moves to the right relative to the placing base 1. At this time, the pitch angle of the material guide table 2 changes, and the height of the right end of the material guide table 2 changes. When the height of the right end of the material guide table 2 meets the conveying height requirement, the push-pull motor 10 is stopped. At this time, the right end of the material guide table 2 is moved above the target position, and the placing base 1 and the transverse base 7 are fixed to the ground by bolt connection. At this time, the entire equipment completes the fixing process.

[0030] The deflection drive motor 31 is started. The deflection drive motor 31 makes the rotating column 25 rotate forward and reverse continuously through the cooperation of the sliding bar 34 and the rotating head 35, so that the deflection plate 26 deflects left and right, so that the upper triangular scraper 21 moves left and right continuously. At this time, the ore that needs to be transported to a high place can be dumped on the left side of the guide platform 2. At this time, if the odd-numbered triangular scraper 21 moves to the right, the odd-numbered triangular scraper 21 will push the ore on the left side of the even-numbered triangular scraper 21 to the even-numbered triangular scraper 21. On the right side of the angle scraper 21, when the even-numbered triangular scraper 21 moves to the right, the even-numbered triangular scraper 21 will push the ore on the left side of the odd-numbered triangular scraper 21 to the right side of the odd-numbered triangular scraper 21, so that the ore will intermittently transfer from left to right between two adjacent triangular scrapers 21, and finally the ore will move to the rightmost end of the guide platform 2, and the ore will be pushed to the right by the rightmost triangular scraper 21, so that the ore falls from the right end of the guide platform 2, thereby completing the entire conveying process. And when the ore turns over the triangular scraper 21, that is, when the ore just crosses the triangular scraper 21 and falls to the surface of the guide platform 2, the ore will collide with the guide platform 2, and the ore itself will also collide with each other, so that the ore that was originally gathered together is broken into small pieces, achieving a preliminary crushing process, and at the same time, the soil particles attached to the surface of the ore will fall and pass through the screening holes 17 and fall to the ground, thereby achieving a screening process.

[0031] The present invention is applicable to a coal mine conveying device, which arranges a plurality of triangular scrapers 21 to move alternately left and right, so that the ore can be transferred between different triangular scrapers 21 along the same direction, and finally the ore can be moved to a high place of a material guide platform 2 and dropped to complete the conveying work. The entire conveying equipment only needs to arrange a driving unit at the end of the material guide platform 2 to control the movement of all triangular scrapers 21. The structure is simple and will not affect the normal work due to harsh environment such as dust. The stability and reliability are better. When the ore is transferred on the triangular scraper 21, it will collide and break, and the soil particles attached to the surface will fall through the screening holes 17, thereby realizing the preliminary screening and crushing of the ore and improving the work efficiency.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
