Description

Technical Field

[0001] The present invention belongs to the technical field of transportation equipment, and specifically relates to a two-way side-turning mechanism for the hopper of a trackless rubber-tired material vehicle. Background Art

[0002] A trackless rubber-tired material vehicle is a material transportation vehicle, which is usually used underground in coal mines to transport materials such as coal and gangue. The trackless rubber-tired material vehicle usually uses a hopper to load materials. After the trackless rubber-tired material vehicle travels to a designated position for unloading, the hopper will be driven to turn sideways by a side-turning mechanism to carry out the unloading work.

[0003] The patent with the publication number CN216661828U discloses a two-way side-turning mechanism for the hopper of a trackless rubber-tired material vehicle, including a material vehicle. One side of the top end of the material vehicle is fixedly installed with a rear frame. The top surface of the rear frame is provided with a hopper assembly. The hopper assembly includes a hopper skeleton and a hopper bottom plate. Both sides of the hopper bottom plate are fixedly connected with side unloading plates. The structure of this patent is simple, the operation is convenient and fast, the manufacturing cost is low, and the performance is safe and reliable. When unloading, no matter which side needs to unload, only the fixed pin on this side of the hopper assembly needs to be pulled out and the fixed pin shaft on the opposite side of the rear frame needs to be taken out to complete the unloading work. It can realize two-way side-turning unloading operation, effectively improve the work efficiency, and has very good practicability.

[0004] However, the above technical solution still has the following deficiencies in actual application:

[0005] Although the hopper can be turned sideways to unload materials, in some cases, a receiving box will be placed at the unloading place of the hopper, and the materials poured out of the hopper will fall into the receiving box so that workers can transfer and store the materials. Since the specification of the hopper is fixed, when the hopper dumps materials, the falling area of the materials is also fixed. When the opening area of the receiving box is smaller than the falling area of the materials, it is possible that the materials will fall into the area outside the receiving box, thus affecting the normal receiving of the materials. And when the falling area of the materials is set too small to avoid this situation, it will lead to slower unloading and affect the unloading efficiency. Summary of the Invention

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. For the two-way side-turning mechanism of the hopper of the trackless rubber-tired material vehicle described in the present invention, during unloading, according to the direction of unloading required, open the box door on the corresponding side, use the hydraulic cylinder to drive the slider to slide on the base, so that the guide column moves horizontally and moves at the chute of the chute plate, and the chute plate and the rotating shaft rotate, so that the hopper tilts in the unloading direction, and the materials in the hopper can be poured out, completing the unloading work. Thus, through the two-way side-turning unloading method, the flexibility of unloading is increased and the unloading efficiency is improved.

[0021] 2. For the two-way side-turning mechanism of the hopper of the trackless rubber-tired material vehicle described in the present invention, by using the adjustable hopper opening adaptive docking mechanism, when the hopper pours the materials inside it into the receiving box, the materials will move along the channel formed by the aggregation plate, the docking plate and the extension plate into the receiving box, and the falling range of the materials is restricted. There will be no situation where the materials spill outside the receiving box because the falling area of the materials is larger than the opening area of the receiving box. Moreover, since the spacing of the aggregation plates depends on the width of the opening of the receiving box, to the greatest extent, the unloading speed is guaranteed and the unloading efficiency is improved. And during the falling process of the materials, they will collapse due to the blocking of the first adjusting plate and the second adjusting plate until they can pass through. Since the height of the materials is reduced, the situation where the materials fall out from the opposite side of the contact point between the extension plate and the hopper opening of the receiving box is avoided. And since the positions of the first adjusting plate and the second adjusting plate are adjustable, to the greatest extent, the unloading speed of the materials is guaranteed. At the same time, by using the adjustable hopper opening adaptive anti-overflow mechanism, when the materials are locally piled up too high in the receiving box, the piled-up materials can be pushed down by the horizontal movement of the first push plate and the second push plate. And since the total length of the first push plate and the second push plate is equal to the width of the receiving box, there will be no pushing dead angle, further ensuring the collapse of the materials, thus avoiding the situation where the materials fall into the receiving box and then overflow from the edge of the receiving box due to being piled up at the same place inside the receiving box.

[0033] Please refer to Figures 1-8, the present invention provides a technical solution: a bidirectional side-turning mechanism for the hopper of a trackless rubber-tired material vehicle, including a base 1.

[0037] Specifically, the base 1 is installed on a trackless rubber-tired material vehicle. The hopper 7 is used to load materials. During discharging, according to the discharging direction required, the corresponding side box door 31 is opened. The opening and closing of the box door 31 are controlled by a bolt, which is prior art and will not be elaborated here; then the hydraulic cylinder 3 is used to drive the slider 4 to slide on the base 1, so that the guiding column 6 moves horizontally and moves in the chute of the chute plate 5, and the chute plate 5 and the rotating shaft 35 rotate, making the hopper 7 tilt in the discharging direction, and the materials in the hopper 7 can be poured out to complete the discharging work.

[0042] An adjustable box opening adaptive anti-overflow mechanism for preventing materials from overflowing from the receiving box during the unloading process is also provided on the second adjusting plate 17;

[0043] The adjustable box opening adaptive anti-overflow mechanism includes two second sliding rods 20 slidably connected to one side of the upper end of the second adjusting plate 17. One end of the second sliding rod 20 is fixedly connected with a limiting block 21. One side of the limiting block 21 is slidably connected with a rack bar 13. The lower end of the rack bar 13 is fixedly connected with a first pushing plate 25. The inner side of the first pushing plate 25 is inserted and slidably connected with a second pushing plate 26.

[0044] An electric push rod 19 is fixedly connected to one side of the upper end of the second adjusting plate 17. The piston end of the electric push rod 19 is fixedly connected to one side of the limiting block 21. A first gear 23 is rotatably arranged on one side of the limiting block 21. The first gear 23 meshes with the tooth blocks on the rack bar 13. A third motor 24 is fixedly connected to one side of the limiting block 21.

One end of the second connecting rod 28 is rotatably connected to one side of the upper end of the second pushing plate 26. A fourth motor 27 is fixedly connected to one side of the upper end of the first pushing plate 25. The output end of the fourth motor 27 is fixedly connected to one end of the third connecting rod 29.

[0046] Specifically, in the prior art, although the material box 7 can be overturned to unload materials, in some cases, a receiving box is placed at the unloading position of the material box 7, and the materials poured out of the material box 7 will fall into the receiving box for workers to transfer and store the materials. Since the specifications of the material box 7 are fixed, when the material box 7 dumps materials, the falling area of the materials is also fixed. When the opening area of the receiving box is smaller than the falling area of the materials, it may occur that the materials fall into the area outside the receiving box, thus affecting the normal receiving of the materials. In order to avoid this situation, when the falling area of the materials is set too small, the unloading speed will be slow, affecting the unloading efficiency;

[0047] Therefore, to solve the above problems, during the use of this embodiment, a rectangular receiving box for receiving the materials in the material box 7 is placed on one side of the trackless rubber-tired vehicle. The rectangular receiving box is a relatively common material collection box. According to the size of the opening of the receiving box, first, the first motor 10 drives the bidirectional threaded rod 12 to rotate, adjusting the distance between the two gathering plates 9 on both sides so that the distance between the two gathering plates 9 is equal to the width of the opening of the receiving box. Then, the material box 7 is driven to turn over towards the receiving box. Then, the two motors five 30 on both sides drive the two second gears 34 to rotate in the same direction simultaneously, making the extension plate 8 approach the opening of the receiving box. Moreover, in the initial state, both of the two second gears 34 are engaged with the tooth blocks on the extension plate 8. When the extension plate 8 moves to one side, one of the second gears 34 will disengage from the tooth blocks on the extension plate 8, and the other second gear 34 will drive the extension plate 8 to move until the extension plate 8 fits against the edge of the opening of the receiving box. Then, the box door 31 is opened, and the materials will move into the receiving box along with the extension plate 8. At the same time, the corresponding second motor 15 is started, and the docking plate 14 can slide inside the gathering plate 9 under the rotation of the fourth connecting rod 33 and the first connecting rod 22 until the ends of both docking plates 14 contact the edges on both sides of the receiving box. At this time, the materials poured out from the material box 7 will move into the receiving box along the channel formed by the gathering plate 9, the docking plate 14, and the extension plate 8, and the feeding range of the materials is restricted. Therefore, the situation where the materials spill outside the receiving box due to the feeding area of the materials being larger than the opening area of the receiving box will not occur. Moreover, since the distance between the gathering plates 9 depends on the width of the opening of the receiving box, the discharging speed is guaranteed to the greatest extent, and the discharging efficiency is improved;

[0048] Although the feeding area of the materials can be restricted in the above manner, however, when the materials in the material box 7 are piled up too high, the materials may still fall out from the opposite side of the contact between the extension plate 8 and the opening of the receiving box. Therefore, to avoid this situation, when the end of the extension plate 8 contacts the edge of the receiving box, according to the horizontal distance between the end of the extension plate 8 and the edge of the receiving box on its opposite side, the sixth motor 32 drives the first threaded rod 18 to rotate, making the second adjusting plate 17 slide longitudinally on the docking plate 14. Moreover, since the second adjusting plate 17 and the first adjusting plate 16 are always inserted into each other, the first adjusting plate 16 will also move until the distance between the bottom of the second adjusting plate 17 and the upper end surface of the extension plate 8 is less than the above horizontal distance. During the falling process of the materials, they will collapse due to the blocking of the first adjusting plate 16 and the second adjusting plate 17 until they can pass through. Since the height of the materials is reduced, the situation where the materials fall out from the opposite side of the contact between the extension plate 8 and the opening of the receiving box is avoided. Moreover, since the orientations of the first adjusting plate 16 and the second adjusting plate 17 can be adjusted, the discharging speed of the materials is also guaranteed to the greatest extent;

[0049] Although the feeding range of the material is restricted in multiple directions, after the material falls into the inside of the receiving box, it will accumulate at the same place inside the receiving box. This may cause the material inside the receiving box to accumulate too high locally due to uneven distribution, resulting in the situation of overflowing from the edge of the receiving box, causing trouble. Therefore, to avoid this situation, when the material box 7 discharges materials, the material box 7 is in an inclined state. At this time, the rack bar 13 is perpendicular to the upper surface of the receiving box. And because one side of the first push plate 25 is flush with one side of the second adjusting plate 17, the first push plate 25 must be within the opening range of the receiving box. At this time, by driving the third connecting rod 29 and the second connecting rod 28 to rotate through the fourth motor 27, the second push plate 26 slides inside the first push plate 25 until the total length formed by the first push plate 25 and the second push plate 26 is equal to the opening width of the receiving box. Then, by driving the first gear 23 to rotate through the third motor 24, the rack bar 13 descends, and the first push plate 25 and the second push plate 26 extend into the inside of the receiving box. When the material accumulates too high locally in the receiving box, by driving the limit block 21 to move horizontally through the electric push rod 19, the material that has accumulated too high can be pushed down by the horizontal movement of the first push plate 25 and the second push plate 26. And because the total length of the first push plate 25 and the second push plate 26 is equal to the width of the receiving box, there will be no dead angle in pushing, further ensuring the collapse of the material, thus avoiding the situation that after the material falls into the inside of the receiving box, it accumulates at the same place inside the receiving box and then overflows from the edge of the receiving box.

[0050] Working principle: Install the base 1 on the trackless rubber-tired material vehicle. The material box 7 is used to load materials. When discharging materials, according to the discharging direction required, open the box door 31 on the corresponding side. The opening and closing of the box door 31 are controlled by bolts. This is the prior art and will not be elaborated here. Then, use the hydraulic cylinder 3 to drive the slider 4 to slide on the base 1, so that the guide column 6 moves horizontally and moves in the chute of the chute plate 5. The chute plate 5 and the rotating shaft 35 rotate, so that the material box 7 tilts in the discharging direction, and the materials in the material box 7 can be poured out, completing the discharging work. Thus, through the way of double-sided side tipping discharging, the flexibility of discharging is increased and the discharging efficiency is improved. Place the rectangular receiving box used to receive the materials in the material box 7 on one side of the trackless rubber-tired material vehicle. The rectangular receiving box is a relatively common material collection box. According to the size of the opening of the receiving box, first use the first motor 10 to drive the bidirectional threaded rod 12 to rotate, and adjust the distance between the two gathering plates 9 on both sides, so that the distance between the two gathering plates 9 on both sides is equal to the width of the opening of the receiving box. Then, drive the material box 7 to tip towards the receiving box. Then, use the two motors five 30 on both sides to drive the two second gears 34 to rotate in the same direction at the same time, so that the extension plate 8 approaches the opening of the receiving box. And, in the initial state, both of the two second gears 34 are engaged with the tooth blocks on the extension plate 8. When the extension plate 8 moves to one side, one of the second gears 34 will disengage from the tooth blocks on the extension plate 8, and the other second gear 34 will drive the extension plate 8 to move until the extension plate 8 fits the edge of the opening of the receiving box. Then, open the box door 31, and the materials will move into the receiving box along with the extension plate 8. At the same time, start the second motor 15 at the corresponding position, and then, under the rotation of the fourth connecting rod 33 and the first connecting rod 22, the docking plate 14 can slide inside the gathering plate 9 until the ends of the two docking plates 14 contact the edges on both sides of the receiving box. At this time, the materials poured out from the material box 7 will move into the receiving box along the channel formed by the gathering plate 9, the docking plate 14, and the extension plate 8. And the discharging range of the materials is limited. Therefore, the situation that the materials are scattered outside the receiving box due to the discharging area of the materials being larger than the opening area of the receiving box will not occur. And, since the distance between the gathering plates 9 depends on the width of the opening of the receiving box, to the greatest extent, the discharging speed is guaranteed and the discharging efficiency is improved;Although the blanking area of the material can be restricted through the above method, however, when the material in the material box 7 accumulates too high, the material may still fall out from the opposite side of the contact between the extension plate 8 and the opening of the receiving box. Therefore, to avoid this situation, when the end of the extension plate 8 contacts the edge of the receiving box, according to the horizontal distance between the end of the extension plate 8 and the edge of the receiving box opposite thereto, the motor six 32 is used to drive the threaded rod one 18 to rotate, so that the adjusting plate two 17 slides longitudinally on the docking plate 14. And because the adjusting plate two 17 and the adjusting plate one 16 always remain plugged, the adjusting plate one 16 will also move until the distance between the bottom of the adjusting plate two 17 and the upper surface of the extension plate 8 is less than the above horizontal distance. During the falling process of the material, it will collapse due to the blockage of the adjusting plate one 16 and the adjusting plate two 17 until it can pass through. Since the height of the material is reduced, the situation where the material falls out from the opposite side of the contact between the extension plate 8 and the opening of the receiving box is avoided. And because the orientations of the adjusting plate one 16 and the adjusting plate two 17 can be adjusted, the blanking speed of the material is also guaranteed to the greatest extent. Although the blanking range of the material is restricted in multiple directions, after the material falls into the receiving box, it will accumulate at the same place inside the receiving box, which may cause the material inside the receiving box to be locally piled up too high due to uneven distribution, resulting in the situation of overflowing from the edge of the receiving box and causing trouble. Therefore, to avoid this situation, when the material box 7 discharges materials, the material box 7 is in an inclined state. At this time, the rack bar 13 is perpendicular to the upper surface of the receiving box. And because one side of the push plate one 25 is flush with one side of the adjusting plate two 17, the push plate one 25 must be within the opening range of the receiving box. At this time, by driving the connecting rod three 29 and the connecting rod two 28 to rotate through the motor four 27, the push plate two 26 slides inside the push plate one 25 until the total length formed by the push plate one 25 and the push plate two 26 is equal to the opening width of the receiving box. Then, by driving the gear one 23 to rotate through the motor three 24, the rack bar 13 is lowered, and the push plate one 25 and the push plate two 26 are extended into the receiving box. When the material is locally piled up too high inside the receiving box, the electric push rod 19 is used to drive the limit block 21 to move horizontally, and the piled-up material can be pushed down by the horizontal movement of the push plate one 25 and the push plate two 26. And because the total length of the push plate one 25 and the push plate two 26 is equal to the width of the receiving box, there will be no dead angle in pushing, further ensuring the collapse of the material, thus avoiding the situation where the material overflows from the edge of the receiving box after falling into the receiving box due to accumulating at the same place inside the receiving box.;

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention.
