Description

Technical Field

[0001] The invention belongs to the technical field of transportation equipment, in particular to a bidirectional rollover mechanism for a material box of a trackless rubber-wheeled material vehicle. Background Art

[0002] A trackless rubber-wheeled material truck is a material transport vehicle, which is usually used underground in coal mines to transport materials such as coal and gangue. The trackless rubber-wheeled material truck usually uses a material box to load materials. When the trackless rubber-wheeled material truck drives to the designated location to unload, the rollover mechanism will drive the material box to roll over to carry out the unloading work.

[0003] The patent with announcement number CN216661828U discloses a two-way rollover mechanism for a material box of a trackless rubber-wheeled material cart, including a material cart, a rear frame is fixedly installed on one side of the top of the material cart, a material box assembly is arranged on the top surface of the rear frame, the material box assembly includes a material box frame and a material box bottom plate, and side unloading plates are fixedly connected on both sides of the material box bottom plate; the patent has a simple structure, convenient and fast operation, low manufacturing cost and safe and reliable performance. When unloading, whichever side needs to be unloaded, only the fixed pin of the material box assembly on that side needs to be unloaded and the fixed pin shaft on the opposite side of the rear frame need to be taken out to complete the unloading work, and the two-way rollover unloading operation can be realized, which effectively improves the work efficiency and has very good practicality.

[0004] However, the above technical solution still has the following deficiencies in practical application: Although unloading can be carried out by driving the material box to tip over, in some cases, a receiving box will be placed at the material box unloading location, and the material dumped from the material box will fall into the receiving box so that workers can transfer and store the material. Since the specifications of the material box are fixed, the area where the material falls when the material box is dumped is also fixed. When the opening area of ​​the receiving box is smaller than the material falling area, the material may fall into the area outside the receiving box, thereby affecting the normal receiving of the material. In order to avoid this situation, the material falling area is set too small, which will lead to slower unloading and affect the unloading efficiency. Summary of the invention

[0016] The beneficial effects of the present invention are as follows: 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, the corresponding side box door is opened. The hydraulic cylinder is used to drive the slider to slide on the base, so that the guiding column moves horizontally and moves at the chute of the chute plate. 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.

[0017] 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 adaptative docking mechanism, when the hopper pours the materials inside it into the receiving box, the materials will move along the channel formed by the gathering plate, the docking plate and the extension plate into the receiving box. The falling range of the materials is limited, and the situation that the materials spill outside the receiving box due to the falling area of the materials being larger than the opening area of the receiving box will not occur. And because the distance between the gathering 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 that the materials fall out from the opposite side of the contact part between the extension plate and the hopper opening of the receiving box is avoided. And because 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 also guaranteed. At the same time, by using the adjustable hopper adaptative 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 transverse movement of the first push plate and the second push plate. And because 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 that 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] Specifically, in the prior art, although the material box 7 can be dumped 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, the materials may fall into areas 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, the unloading speed will be slow, affecting the unloading efficiency; 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. 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 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 then, under the rotation of the fourth connecting rod 33 and the first connecting rod 22, the docking plate 14 slides inside the gathering plate 9 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. Moreover, the falling range of the materials is restricted. Therefore, the situation where the materials spill outside the receiving box due to the falling 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, the unloading speed is guaranteed to the greatest extent, improving the unloading efficiency; Although the falling area of the materials can be restricted in the above way, however, when the materials in the material box 7 are stacked 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 the 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. And, since the second adjusting plate 17 and the first adjusting plate 16 are always plugged 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 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. And, since the orientations of the first adjusting plate 16 and the second adjusting plate 17 can be adjusted, the unloading speed of the materials is also guaranteed to the greatest extent; 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 since 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 inside the receiving box, by driving the limiting block 21 to move horizontally through the electric push rod 19, the material that accumulates too high can be pushed down by the horizontal movement of the first push plate 25 and the second push plate 26. And since 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.

[0034] 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 is controlled by a bolt, which is an existing technology 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 for 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 double-threaded screw 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 extension plate 8 will be driven by the other second gear 34 until the extension plate 8 fits against 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 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 the two docking plates 14 are in contact with 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. Moreover, the falling range of the materials is limited. Therefore, the situation that the materials spill outside the receiving box due to the falling 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, the discharging speed is guaranteed to the greatest extent and the discharging efficiency is improved;Although the feeding area of the material can be restricted by the above method, 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 on the opposite side, the motor six 32 drives the lead screw 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 maintain a plug-in connection, 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 blocking 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 discharging speed of the material is also guaranteed to the greatest extent. Although the feeding 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 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 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 of 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 descends and the push plate one 25 and the push plate two 26 extend into the receiving box. When the material accumulates too high locally in the receiving box, the electric push rod 19 drives the limit block 21 to move horizontally, and the accumulated high 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 and accumulating at the same place inside the receiving box.;
