DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-Figure 6As shown, a bidirectional conveyor belt machine for mining comprises a bracket 1, a belt dragging mechanism, a lifting mechanism, a conveyor belt 4 and an electric control system. The left and right parts of the bracket 1 are each equipped with a belt dragging mechanism, and the middle part is equipped with a lifting mechanism. The lifting mechanism comprises a main lifting roller 6 and a lifting piece. The upper and lower parts of the bracket 1 are respectively rotatably connected with a plurality of main lifting rollers 6 arranged in the left and right directions. The upper and lower parts of the bracket 1 are respectively equipped with a plurality of groups of lifting pieces. Two lifting pieces arranged front and back oppositely form a group. One group of lifting pieces comprises a left sliding seat 8 and a right sliding seat 9. The bracket 1 is slidably connected with the left sliding seat 8 and the right sliding seat 9 front and back. The upper parts of the left sliding seat 8 and the right sliding seat 9 are hinged with a left supporting seat 10 and a right supporting seat 11 swinging along the side plane in sequence. The left supporting seat 10 is fixed with a secondary reduction motor 12. Angle reducers are respectively installed between the left supporting seat 10 and the left sliding seat 8 and between the right supporting seat 11 and the right sliding seat 9. Adjustment mechanism, the right support seat 11 is slidably connected to a sliding support 14 left and right, the left support seat 10 and the sliding support 14 are respectively rotatably connected to auxiliary lifting rollers 15, the rotating shaft of the auxiliary reduction motor 12 is coaxially fixed with the auxiliary lifting roller 15 rotatably connected to the left support seat 10, and the two auxiliary lifting rollers 15 in each lifting member are rotatably connected to a conveyor belt 16 together, and a plurality of tension springs 17 are fixed between the sliding support 14 and the right support seat 11, and have a tendency to straighten the conveyor belt 16 under the elastic tension of the tension spring 17, and a push-pull mechanism in the front and rear directions is installed between the left sliding seat 8 and the right sliding seat 9 and the bracket 1, the belt dragging mechanism and the main lifting roller 6 roll and rub together and are sleeved with a conveyor belt 4, and the front and rear parts of the conveyor belt 4 roll and rub with the conveyor belt 16, the electric control system is externally connected to a power supply, and is electrically connected to the auxiliary reduction motor 12, and the electric control system is a known prior art, such as an industrial computer.

[0024] When in use, the length of the bracket 1 in the left and right directions can be extended during production according to the needs of use. The conveyor belt 4 is driven to rotate by the belt dragging mechanism, and the auxiliary lifting roller 15 is controlled to rotate so that the conveyor steel belt 16 rotates at the same speed as the conveyor belt 4, and the objects are placed on the top and bottom of the upper part of the conveyor belt 4 to realize the transportation of the objects. When it is necessary to detach, it can be cleaned by an external cleaning mechanism (such as using a scraper to contact the conveyor belt 4 to achieve scraping, which is a prior art and will not be repeated here). The angle of the left support seat 10 and the right support seat 11 relative to the main lifting roller 6 is adjusted by controlling the angle adjustment mechanism, that is, the angle of the auxiliary lifting roller 15 relative to the main lifting roller 6 is adjusted, so that the middle part of the conveyor belt 4 is bent to concentrate it to the upper middle part, thereby reducing the drop of objects during transportation. When the steel belt is in a twisted state, the bending angle of the conveyor belt 4 can be indirectly changed, thereby realizing centralized or dispersed transportation of objects. By controlling the push-pull mechanism and the angle adjustment mechanism, the position of the auxiliary lifting roller 15 relative to the main lifting roller 6 can be adjusted. When a larger space is left on one of the front and rear sides, the object on the conveyor belt 4 can be offset toward the spatial position, indirectly causing the conveyor belt 4 to be offset, thereby achieving a deviation correction effect. On the other hand, by adjusting the rotation speed of the auxiliary reduction motor 12, the rotation speed of the conveyor steel belts 16 on the front and rear sides of the bracket 1 is increased on one side and decreased on the other side relative to the rotation speed of the conveyor belt 4. Then, by utilizing the friction between the conveyor steel belt 16 and the conveyor belt 4, the conveyor belt 4 can have a tendency to move toward the side of the conveyor steel belt 16 with a faster rotation speed, thereby also achieving deviation correction.

[0025] The belt dragging mechanism includes a No. 1 auxiliary drag roller 19, a No. 2 auxiliary drag roller 20, a No. 3 auxiliary drag roller 21, an adjusting seat 22, a main drag roller 23, a main reduction motor 24, a screw rod 25, a nut 26, and a washer 27. The left and right parts of the bracket 1 are rotatably connected with the horizontal No. 1 auxiliary drag roller 19, the No. 2 auxiliary drag roller 20, and the No. 3 auxiliary drag roller 21 from top to bottom in sequence. The left and right parts of the bracket 1 are each slidably connected with a group of adjusting seats 22. Two adjusting seats 22 corresponding to each other front and back form a group. Each group of adjusting seats 22 is respectively rotatably connected with a horizontal main drag roller 23. Any adjusting seat 22 in each group of the adjusting seats 22 is fixed with a main reduction motor 24. The rotating shaft of the main reduction motor 24 is connected to the main The drag roller 23 is fixed on the same axis, and a horizontal screw rod 25 is fixed in the left and right directions of the adjustment seat 22. Each screw rod 25 is threadedly connected with at least two nuts 26. Two washers 27 are inserted in the gap on the screw rod 25. The washers 27 are located between the nuts 26. The nuts 26 on the screw rod 25 clamp the bracket 1 through the washers 27 to limit the position of the screw rod 25 relative to the bracket 1. The left and right parts of the conveyor belt 4 roll and rub with the first auxiliary drag roller 19 and the second auxiliary drag roller 20, then turn through the main drag roller 23, and then roll and rub and turn to the top of the main lifting roller 6 at the bottom of the bracket 1 through the third auxiliary drag roller 21. The main reduction motor 24 is electrically connected to the electronic control system.

[0026] Furthermore, by controlling the main reduction motor 24 to rotate, the conveyor belt 4 can be driven to rotate. When the conveyor belt 4 passes through the No. 1 auxiliary drag roller 19, the No. 2 auxiliary drag roller 20, and the No. 3 auxiliary drag roller 21, it is relatively flat, which is conducive to throwing objects into the conveyor belt 4 or making the objects separate from the conveyor belt 4. By rotating the nut 26 so that the nut 26 is located at different positions of the screw rod 25, and then clamping the bracket 1 through the washer 27, the left and right position of the main drag roller 23 relative to the bracket 1 can be adjusted, thereby realizing the tightening of the conveyor belt 4.

[0027] The left and right parts of the bracket 1 are each equipped with a detection mechanism, and the detection mechanism includes a support plate 29, a support ring 30, a compression spring 31, a mounting seat 32, and a distance sensor 33. The front and rear ends of the No. 1 auxiliary drag roller 19, the No. 2 auxiliary drag roller 20, and the No. 3 auxiliary drag roller 21 are respectively fixed with support plates 29, and the front and rear parts are respectively axially slidably connected with support rings 30. A plurality of compression springs 31 are fixed between the support plate 29 and the support ring 30. The support ring 30 has a tendency to approach each other under the elastic repulsive force of the compression spring 31 until it is close to the conveyor belt. 4 are in contact with each other, the left and right parts of the bracket 1 are each fixed with multiple groups of mounting seats 32, the two mounting seats 32 corresponding to each other front and back are a group, each group of the mounting seats 32 corresponds to the first auxiliary drag roller 19, the second auxiliary drag roller 20 and the third auxiliary drag roller 21 front and back in sequence, each of the mounting seats 32 is respectively fixed with a horizontal distance sensor 33, the distance sensors 33 fixed by each group of the mounting seats 32 correspond to each other front and back, the distance sensors 33 are used to measure the horizontal distance between adjacent support rings 30, and the distance sensors 33 are electrically connected to the electric control system.

[0028] Furthermore, under the elastic repulsive force of the compression spring 31, the support ring 30 contacts the conveyor belt 4, and the horizontal distance of the support ring 30 is detected by the distance measuring sensor 33, so that the front and rear positions of the conveyor belt 4 relative to the bracket 1 can be determined, and then it is convenient to timely detect whether the conveyor belt 4 is deviated.

[0029] The angle adjustment mechanism is an auxiliary electric push rod 34, and the left sliding seat 8 and the right sliding seat 9 are respectively hinged with auxiliary electric push rods 34 along the side plane. The push rod of the auxiliary electric push rod 34 is hinged with the left support seat 10 or the right support seat 11 along the side plane. The push-pull mechanism is a main electric push rod 35. The bracket 1 is fixed with multiple horizontal main electric push rods 35 along the front and rear directions. The push rod of the main electric push rod 35 is fixed with the left sliding seat 8 or the right sliding seat 9. The auxiliary electric push rod 34 and the main electric push rod 35 are electrically connected to the electric control system. The two axial ends of the auxiliary lifting roller 15 are respectively fixed with limiting rings 36, and the conveying steel belt 16 is located between the limiting rings 36 at the two axial ends of the auxiliary lifting roller 15.

[0030] Furthermore, by controlling the extension and retraction of the auxiliary electric push rod 34, the left support seat 10 and the right support seat 11 can be swung up and down, thereby adjusting the angle of the left support seat 10 and the right support seat 11 relative to the main lifting roller 6. When the angles are inconsistent, the conveyor steel belt 16 is twisted. By controlling the extension and retraction of the main electric push rod 35, the front and rear positions of the left sliding seat 8 and the right sliding seat 9 relative to the bracket 1 can be adjusted, thereby adjusting the front and rear positions of the conveyor steel belt 16 relative to the bracket 1. Subsequently, the above steps are used to adjust the space size of the conveyor steel belt 16 relative to the main lifting roller 6, and the position of the conveyor steel belt 16 can be limited by using the limit ring 36.

[0031] A plurality of vertical gantries 37 are fixed in sequence from left to right on the upper part of the bracket 1, a vertical upper electric push rod 38 is fixed to the top of each gantry 37, a vertical upper lifting frame 39 is fixed to the bottom of each upper electric push rod 38, the upper lifting frame 39 is connected to the gantry 37 in an up and down sliding manner, a vertical guide plate 40 is fixed to the front and rear parts of the bottom of the upper lifting frame 39, the guide plates 40 of the front and rear parts of the upper lifting frame 39 are tilted and gathered toward the middle right, and the upper electric push rod 38 is electrically connected to the electric control system.

[0032] By controlling the extension and retraction of the upper electric push rod 38, the height position of the guide plate 40 relative to the conveyor belt 4 can be adjusted. When the objects on the conveyor belt 4 are of different sizes (such as ore), the height of the large object is significantly greater than that of the small object. By making the guide plate 40 touch the large object, the large object can be guided to the middle of the conveyor belt 4, so that the conveyor belt 4 is subjected to more uniform force when transporting objects, thereby reducing deviation.

[0033] A plurality of sieve slots 41 are horizontally penetrated through the bottom of the guide plate 40 , and each of the sieve slots 41 penetrates downwardly through the bottom end of the guide plate 40 .

[0034] Furthermore, the guide plate 40 can be brought closer to the conveyor belt 4, and then the objects of corresponding sizes can be screened and guided through the screening slot 41, so that these objects can be concentrated more toward the middle of the conveyor belt 4, while reducing the concentration of small objects.

[0035] The bracket 1 is fixed with multiple speed regulating motors 42 in sequence from left to right, and a crankshaft 43 is coaxially fixed to the rotating shaft of the speed regulating motor 42. The bracket 1 is slidably connected to multiple lower lifting frames 44 up and down, and the upper part of each lower lifting frame 44 is connected to a contact roller 45 that rotates along the front-back direction. The contact roller 45 rolls and rubs with the upper part of the conveyor belt 4. A horizontal straight groove 46 is fixed to the bottom of the lower lifting frame 44, and the connecting rod journal of the crankshaft 43 is gap inserted in the straight groove 46. Each speed regulating motor 42 is electrically connected to the electronic control system.

[0036] Furthermore, by controlling the speed regulating motor 42 to rotate, the crankshaft 43 can be used to make the lower lifting frame 44 move up and down frequently, so that the contact roller 45 can be used to push the conveyor belt 4 to achieve a vibration effect. During the vibration process, small objects and large objects can be mixed more tightly, and under the guidance of the aforementioned guide plate 40, the relative positions of large objects can be well defined, reducing the accidental movement of large objects, so that the force on the conveyor belt 4 is more uniform and lasting, and the deviation is reduced.

[0037] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
