However, since soil and rocks are mixed together in the tunnel, existing conveying devices often mix these materials and transport them out together. When the conveyor belt transfers soil and rocks to the muck truck, since the conveyor belt is installed above the inside of the shield machine, there is a significant height difference between the unloading end and the muck truck, which makes it easy for rocks or larger rocks to hit the inner wall of the muck truck. The impact will cause damage to the muck truck and shorten the normal service life of the muck truck.

[0020] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0021] In this embodiment, please refer to Figures 1 to 8 The present invention provides a tunnel construction engineering material conveying equipment, comprising: A conveying mechanism 1 and a support frame 2, wherein the support frame 2 comprises a first support portion 21 and a second support portion 22 fixedly connected to the first support portion 21, and the conveying mechanism 1 is arranged above the first support portion 21; the conveying mechanism 1 is a conveyor belt, and the first support portion 21 provides stable support for the conveying mechanism 1 to ensure the stability of conveying; The conveying mechanism 3 includes a first inclined plate 31 obliquely arranged below the unloading end of the conveying mechanism 1, an energy dissipation module 32, and a second inclined plate 33 obliquely arranged in the second supporting portion 22. Both ends of the energy dissipation module 32 are connected to the discharge end of the first inclined plate 31 and the feed end of the second inclined plate 33 through a buffer connection portion 34. The inclination angle of the first inclined plate 31 with the horizontal plane is greater than the inclination angle of the second inclined plate 33. The feed end and the discharge end refer to the two ends where soil and stones enter and leave, respectively. The energy dissipation module 32 includes a rotating shaft 321 rotatably mounted on the second support portion 22, a buffer plate 322 coaxially fixedly matched with the rotating shaft 321, a crossbeam 323 arranged along the width direction of the second support portion 22 and fixedly connected to the inner side wall of the second support portion 22, a blocking component 324 arranged at the discharge end of the buffer plate 322, and an adaptive adjustment component 325 for adjusting the buffer plate 322 from an inclined state to a horizontal state, the bottom of the buffer plate 322 contacts and cooperates with the crossbeam 323, and the buffer plate 322 has a plurality of through holes 326 for soil and small stones to pass through along its length and width direction; the blocking mechanism 4 is arranged perpendicular to the second inclined plate 33, and the blocking mechanism 4 is connected to the energy dissipation module 32 through the transmission mechanism 5, and the blocking mechanism 4 is used to extend the moving path and moving time of large stones on the second inclined plate 33; the muck truck 6 is used to carry soil and stones that slide down from the first inclined plate 31, the buffer plate 322 and the second inclined plate 33 in sequence.

[0022] The soil and stones slide down the inclined first inclined plate 31 to the buffer plate 322 which is initially in a horizontal state, and the large stones remain in the buffer plate 322. The soil and small stones leak down to the inclined second inclined plate 33 through the through holes 326, and the soil and small stones slide along the inclined plate into the muck truck 6. The soil and small stones that fall first are spread on the bottom of the muck truck 6. Under the action of the gravity of the stones themselves, the buffer plate 322 rotates the shaft 321 and the buffer plate 322. Both ends of the buffer plate 322 are connected to the first inclined plate 31 and the second inclined plate 33 after being buffered by the buffer connection part 34, so as to form a smooth conveying path. The rotation of the shaft 321 At the same time, the transmission mechanism 5 drives the blocking mechanism 4 to move upward perpendicularly to the second inclined plate 33, so that the blocking mechanism 4 further prolongs the moving path and moving time of the large rocks on the second inclined plate 33, thereby realizing that the large rocks are delayed from falling into the dump truck 6 before the soil. When the large rocks fall into the dump truck 6, they are in direct contact with the soil, thus avoiding the impact between the large rocks and the dump truck 6. The soil and small stones slide down from the second inclined plate 33, which is conducive to the soil and small stones slowly falling into the dump truck 6, reducing the impact and collision of the soil and small stones on the dump truck 6, extending the service life of the dump truck 6 and the track, and also reducing the splashing and scattering of stones and soil during the sliding process.

[0023] In this embodiment, the energy dissipation modules 32 have at least two groups, and the adjacent energy dissipation modules 32 are arranged in a stepped manner and connected by the buffer connection part 34. When soil and stones fall from the discharge end of the first inclined plate 31, at least two groups of energy dissipation modules 32 are provided and arranged in a stepped manner, so that the materials can experience multiple buffering during the falling process, thereby reducing the falling speed of soil and stones, achieving energy dissipation, and then adapting to the scenes of different material states and flow rates, and improving applicability and practicality.

[0024] In this embodiment, please refer to Figure 3 The adaptive adjustment components 325 have two groups, and the two groups of adaptive adjustment components 325 are symmetrically arranged on both sides of the second support portion 22, thereby enhancing the balance and stability when adjusting the buffer plate 322; The adaptive adjustment assembly 325 includes a 7-shaped arm 3251, an L-shaped arm 3252, a limiting column 3253, a roller 3254 vertically and rotatably mounted at the end of the vertical portion of the L-shaped arm 3252, and an adaptive power member 3255 for resetting the buffer plate 322 from an inclined state to a horizontal state. The intersection of the horizontal portion and the inclined portion of the 7-shaped arm 3251 is coaxially fixedly matched with the rotating shaft 321, the intersection of the horizontal portion and the vertical portion of the L-shaped arm 3252 is rotatably mounted on the side wall of the second support portion 22, the roller 3254 is rollingly matched with the inclined portion of the 7-shaped arm 3251, and the limiting column 3253 is fixedly mounted on the side wall of the second support portion 22 and is located between the L-shaped arm 3252 and the adaptive power member 3255. The adaptive power member 3255 is a spring, and the two ends of the spring are respectively fixedly connected to the horizontal portion of the L-shaped arm 3252 and the side wall of the second support portion 22.

[0025] The 7-shaped arm 3251 is driven to rotate by the rotation of the buffer plate 322 and the rotating shaft 321, and the inclined part of the 7-shaped arm 3251 rolls with the roller 3254 to drive the L-shaped arm 3252 to be pressed downward. The roller 3254 is designed between the L-shaped arm 3252 and the 7-shaped arm 3251, which can not only reduce direct friction, but also provide better sliding performance, making the adaptive adjustment process smoother and more stable, thereby extending the service life. At this time, the adaptive power part 3255 fixedly connected to the horizontal part of the L-shaped arm 3252 is in a stretched state, so that it can adapt to the adjustment requirements of different inclination angles of the buffer plate 322, wherein the limit column 3253 limits excessive movement of the L-shaped arm 3252 and the adaptive power part 3255. When the transportation is completed, the adaptive power part 3255 can reset the buffer plate 322 from the inclined state to the horizontal state, preparing for the next transportation.

[0026] In this embodiment, please refer to Figure 3 The second inclined plate 33 is provided with a plurality of soil leakage holes 331 along its width direction and the length direction inclined downward, and the diameter of the soil leakage holes 331 of the second inclined plate 33 along its length direction inclined downward gradually increases; The widths of the first inclined plate 31 , the buffer plate 322 and the second inclined plate 33 gradually increase; the first inclined plate 31 , the buffer plate 322 and the second inclined plate 33 each have a side plate 332 at both ends along their width direction.

[0027] The multiple soil leakage holes 331 on the second inclined plate 33 help more soil to leak down and be laid on the bottom of the dump truck 6 along the length direction of the dump truck 6, so that stones can avoid direct contact with the bottom of the dump truck 6 when falling, thereby playing a further buffering role for the stones; the apertures of the multiple soil leakage holes 331 gradually increase along the length direction of the second inclined plate 33 tilting downward, so that it can more effectively adapt to soil of different sizes, and there is more soil to be laid at the position where the stones fall, even when the stones fall and roll, they will not directly contact with the bottom of the dump truck 6 and cause collision; the widths of the first inclined plate 31, the buffer plate 322 and the second inclined plate 33 gradually increase, so that the transportation efficiency can be improved and local accumulation and blockage can be avoided; the first inclined plate 31, the buffer plate 322 and the second inclined plate 33 have side plates 332 at both ends along their own width direction, which can not only increase the structural strength, but also play a blocking role to prevent soil and stones from sliding to both sides.

[0028] In this embodiment, please refer to Figure 4 and Figure 5 The blocking assembly 324 includes a blocking plate 3241, two first stop blocks 3242, two second stop blocks 3243, two guide columns 3244, and an adjusting elastic member 3245. The discharge end of the buffer plate 322 has a sliding groove 3246 that slides with the blocking plate 3241. The two first stop blocks 3242 are fixedly connected to the bottom of both ends of the blocking plate 3241 in the width direction. The two second stop blocks 3243 are fixedly connected to the top of the discharge end of the side plate 332 at both ends of the buffer plate 322 in the width direction. The second stop block 3243 has a sliding hole. One end of the two guide columns 3244 is respectively fixedly connected to the two first stop blocks 3242 vertically. The other end passes through the sliding hole on the second stop block 3243 and slides together. The side plates 332 at both ends of the width direction of the second inclined plate 33 have arc grooves 3247 that contact and cooperate with the first stop block 3242. There are two adjusting elastic members 3245, and the two adjusting elastic members 3245 are located between the first stop block 3242 and the second stop block 3243 and are used to reset the blocking plate 3241 toward the buffer plate 322. The adjusting elastic member 3245 is a spring, which is sleeved on the guide column 3244, and the two ends of the spring are respectively abutted or fixedly connected with the first stop block 3242 and the second stop block 3243.

[0029] Through the rotation of the buffer plate 322, when the first stop block 3242 contacts and cooperates with the arc groove 3247, the buffer plate 322 continues to fall due to the gravity of the material, and the first stop block 3242 drives the blocking plate 3241 to slide in the sliding groove 3246. At this time, the guide column 3244 slides in the sliding hole in the second stop block 3243, and the adjusting elastic member 3245 is compressed, so that the large stone slides onto the second inclined plate 33. When the transportation is completed, the rebound force of the adjusting elastic member 3245 is used to reset the blocking plate 3241 to the direction of the buffer plate 322, so that the discharge end of the buffer plate 322 can be flexibly opened and closed.

[0030] In this embodiment, please refer to Figure 4 and Figure 6 The buffer connection part 34 includes a baffle 341, two slide grooves 342 and a first elastic member 343. The two slide grooves 342 are arranged opposite to each other. The two ends of the baffle 341 in the width direction are slidably matched with the two slide grooves 342. The first elastic member 343 is used to push the baffle 341 to slide in the two slide grooves 342. The first elastic member 343 includes a spring. When the buffer plate 322 rotates, the two ends of the baffle 341 in the width direction are slidably matched with the slide grooves 342. The first elastic member 343 is compressed to play a buffering role. The baffle 341 can also block the material. When the buffer connection part 34 is arranged between the first inclined plate 31 and the energy dissipation module 32, the two slide grooves 342 are respectively vertically and fixedly connected to the two ends of the width direction of the feeding end of the buffer plate 322, and one end of the first elastic member 343 is hinged to the top of the middle part of the baffle 341 through a hinge block, and the other end is vertically and fixedly connected to the bottom of the first inclined plate 31; When the buffer connection part 34 is arranged between the energy dissipation module 32 and the second inclined plate 33, the two slide grooves 342 are respectively perpendicular and fixed to the two ends of the width direction of the feeding end of the second inclined plate 33, and one end of the first elastic member 343 is hinged to the top of the middle part of the baffle 341 through a hinge block, and the other end is perpendicular and fixed to the bottom of the buffer plate 322.

[0031] When the buffer plate 322 rotates, the first elastic member 343 is compressed and pushes the baffle plate 341 to slide in the slide groove 342. The compressed first elastic member 343 absorbs the impact force of soil and stones sliding onto the buffer plate 322, so that it can play a buffering role. One end of the first elastic member 343 is hinged to the top of the middle part of the baffle plate 341 through a hinge block, and the other end is vertically and fixedly connected to the first inclined plate 31 or the bottom of the buffer plate 322, so that the baffle plate 341 can produce a certain rotation and displacement when subjected to force, which not only enhances the flexibility and buffering performance of the structure, but also can block soil and stones.

[0032] In this embodiment, please refer to Figure 4 and Figure 6 The buffer connection part 34 also includes two rotating blocks 344 respectively connected to the side walls of the two slide grooves 342, a fixed block 345 fixedly arranged on the baffle 341, two T-shaped slide bars 346 located on both sides of the fixed block 345, and two second elastic members 347. The rotating block 344 has a sliding hole that slidably cooperates with the vertical part of the T-shaped slide bar 346. The ends of the vertical parts of the two T-shaped slide bars 346 are hinged to the fixed block 345. The second elastic member 347 is located between the rotating block 344 and the horizontal part of the T-shaped slide bar 346. The second elastic member 347 includes a spring, which is sleeved between the horizontal part of the T-shaped slide bar 346 and the rotating block 344. The two ends of the spring are respectively abutted or fixedly connected with the horizontal part of the T-shaped slide bar 346 and the rotating block 344.

[0033] During operation, the movement of the baffle 341 drives the fixed block 345 fixed on the baffle 341 to move, the end of the vertical part of the T-shaped slide bar 346 is hinged to the fixed block 345, and the vertical part of the T-shaped slide bar 346 slides in the sliding hole of the rotating block 344. The second elastic member 347 works together with the first elastic member 343. The second elastic member 347 is compressed to absorb impact force, making the buffering more effective and comprehensive, so that it can adaptively adjust the buffering according to the state and flow of the material and automatically adjust the buffering in real time.

[0034] In this embodiment, please refer to Figure 2 , Figure 4 and Figure 7 The transmission mechanism 5 has two groups, and the two groups of transmission mechanisms 5 are symmetrically arranged on both sides of the second support part 22 to ensure the balance of power transmission on both sides when driving the blocking mechanism 4 to move. Each group of the transmission mechanism 5 includes a large gear 51 coaxially fixed with the rotating shaft 321, a small gear 52 rotatably arranged on the side wall of the second support part 22, a rotating shaft 53 rotatably arranged on the top of the second support part 22 through a support plate 53, and a locking assembly 55 for locking the blocking mechanism 4 when it moves up and down perpendicular to the second inclined plate 33. The small gear 52 is meshed with the large gear 51 for transmission, and the small gear 52 is connected to the rotating shaft 53 through an annular transmission part 56, and the annular transmission part 56 is a belt drive wheel group and / or a sprocket drive wheel group.

[0035] The large gear 51 is driven to rotate by rotating the rotating shaft 321, and then the small gear 52 meshing with the large gear 51 is driven to rotate. One end of the annular transmission part 56 rotates coaxially with the small gear 52 to drive the rotating shaft 53 to rotate, thereby transmitting power to the rotating shaft 53. The blocking mechanism 4 is locked by the locking assembly 55 when it moves up and down perpendicular to the second inclined plate 33, ensuring that the blocking mechanism 4 is fixed in position when it moves up and down.

[0036] In this embodiment, please refer to Figure 4 and Figure 7 The locking assembly 55 includes a fixed plate 551, an abutment tube 552, an abutment plate 553, two friction blocks 554, a ratchet 555 and a non-return pawl 556. The fixed plate 551 is coaxially fixedly matched with the rotating shaft 53. The rotating shaft 53 has an external thread. The inner wall of the abutment tube 552 has an internal thread that matches the external thread on the rotating shaft 53. The abutment plate 553 is arranged opposite to the fixed plate 551 and is fixedly connected to the abutment tube 552. The two friction blocks 554 are sleeved on the abutment tube 552. The ratchet 555 is sleeved on the abutment tube 552 and is located between the two friction blocks 554. The non-return pawl 556 is rotatably installed on the support plate 53 and prevents the ratchet 555 from rotating. The fixed plate 551 has an abutment groove 557 that matches the abutment tube 552. The locking assembly 55 may have two groups to improve the locking and fixing capability of the blocking mechanism 4 when it moves up and down.

[0037] When the blocking mechanism 4 moves upward perpendicular to the second inclined plate 33, the abutment cylinder 552 is driven to move axially along the rotating shaft 53 by the positive rotation of the rotating shaft 53, and the rotational movement of the rotating shaft 53 is converted into a linear movement of the abutment cylinder 552. After the abutment plate 553 abuts the two friction blocks 554 and the ratchet 555 with the fixed plate 551, the ratchet 555 sleeved on the abutment cylinder 552 is subjected to the friction force on both sides. As the rotating shaft 53 rotates coaxially, the check pawl 556 cooperates with the ratchet 555 to prevent the ratchet 555 from reversing, so that the position of the blocking mechanism 4 is fixed when it moves upward, so that it can more effectively adapt to the collision between large stones and the blocking mechanism 4. When the blocking mechanism 4 moves downward perpendicular to the second inclined plate 33, the abutment cylinder 552 is driven to move axially along the rotating shaft 53 by the reverse rotation of the rotating shaft 53. At this time, the abutment plate 553 releases the friction plate and the ratchet 555. At this time, the rotating shaft 53 rotates alone, and the blocking mechanism 4 moves downward and resets.

[0038] In this embodiment, please refer to Figure 4 and Figure 8The blocking mechanism 4 includes a driving gear 41 coaxially fixedly matched with the rotating shaft 53, two racks 42 respectively meshing with the driving gear 41 for transmission, a blocking cover plate 43 arranged in parallel with the second inclined plate 33, a rectangular frame 44 with one end perpendicular to and fixedly connected to the top of the blocking cover plate 43, a plurality of V-shaped blocking plates 45 arranged along the length direction of the bottom of the blocking cover plate 43, and a plurality of oblique blocking plates 46 arranged along the length direction of the bottom of the blocking cover plate 43; the rectangular frame 44 passes through the top of the second supporting portion 22, the two racks 42 are relatively arranged in the rectangular frame 44, the opening of the V-shaped blocking plate 45 faces the direction of the stone sliding movement, the oblique blocking plates 46 are provided on both sides of the V-shaped blocking plate 45 and are staggered, and the V-shaped blocking plate 45 and the oblique blocking plate 46 cooperate to change the movement direction and movement path of the stone between the second inclined plate 33 and the blocking cover plate 43.

[0039] The driving gear 41 is driven to rotate by rotating the rotating shaft 53, so that the rotational motion of the driving gear 41 is converted into the linear motion of the rack 42, and then the blocking cover plate 43 is driven to move upward perpendicular to the second inclined plate 33, and is locked by the locking assembly 55 after reaching a certain position. When a stone or a large stone collides with the V-shaped blocking plate 45, it is first guided to both sides by the V-shaped blocking plate 45 to achieve the first redirection, and then the second redirection is achieved by the oblique blocking plates 46 located on both sides of the V-shaped blocking plate 45 and staggered. In addition, the large stone will be further broken and deformed during the rolling and impacting process. The plurality of V-shaped blocking plates 45 have inclined blocking plates 46 on both sides and are staggered, so as to further extend the moving path and moving time of the large rocks on the second inclined plate 33, so that the large rocks are delayed from falling into the dump truck 6 before the soil. When the large rocks fall into the dump truck 6, they are in direct contact with the soil, thus avoiding the impact between the large rocks and the dump truck 6. The soil and small rocks slide off the second inclined plate 33, which is conducive to the soil and small rocks falling slowly into the dump truck 6, reducing the impact of the soil and small rocks on the dump truck 6, and extending the service life of the dump truck 6 and the track.

[0040] Working principle: When the conveying mechanism 1 conveys the soil and stones to the unloading end, the soil and stones slide through the inclined first inclined plate 31 to the buffer plate 322 which is initially in a horizontal state, and the large stones remain in the buffer plate 322. The soil and small stones leak through the through holes 326 to the inclined second inclined plate 33, and the soil and small stones slide along the inclined plate into the muck truck 6. The soil and small stones that fall first are spread on the bottom of the muck truck 6. Under the action of the gravity of the stones themselves, the buffer plate 322 rotates simultaneously with the rotating shaft 321 and the buffer plate 322. When the buffer plate 322 rotates, the first elastic member 343 is compressed and pushes the baffle plate 341 to slide in the chute 342. The compressed first elastic member 343 absorbs the soil and stones that slide to the buffer The impact force on the punch plate 322 can play a buffering role. One end of the first elastic member 343 is hinged to the top of the middle part of the baffle plate 341 through a hinge block, and the other end is vertically and fixedly connected to the first inclined plate 31 or the bottom of the buffer plate 322, so that the baffle plate 341 can produce a certain rotation and displacement when subjected to force, which not only enhances the flexibility and buffering performance of the structure, but also can block soil and stones. Both ends of the buffer plate 322 are connected to the first inclined plate 31 and the second inclined plate 33 after being buffered by the buffer connection part 34. At the same time, when the rotating shaft 321 rotates, the rotating shaft 321 rotates to drive the large gear 51 to rotate, and then drives the small gear 52 meshing with the large gear 51 to rotate. One end of the annular transmission part 56 rotates coaxially with the small gear 52 to drive the rotation The shaft 53 rotates to transmit power to the rotating shaft 53. The rotation of the rotating shaft 53 drives the abutment cylinder 552 to move axially along the rotating shaft 53. The rotational movement of the rotating shaft 53 is converted into a linear movement of the abutment cylinder 552. After the abutment plate 553 abuts the two friction blocks 554 and the ratchet 555 with the fixed plate 551, the ratchet 555 sleeved on the abutment cylinder 552 is subjected to the friction force on both sides. As the rotating shaft 53 coaxially rotates, the non-return pawl 556 cooperates with the ratchet 555 to prevent the ratchet 555 from reversing. When the rotating shaft 53 rotates, it also drives the driving gear 41 to rotate, so that the rotational movement of the driving gear 41 is converted into a linear movement of the rack 42, and then drives the blocking cover plate 43 to move upward perpendicular to the second inclined plate 33 until it reaches a certain After the V-shaped blocking plate 45 is in position, it is locked by the locking assembly 55. When a stone or a large stone collides with the V-shaped blocking plate 45, it is first guided to both sides by the V-shaped blocking plate 45 to achieve the first redirection, and then the second redirection is performed by the oblique blocking plates 46 located on both sides of the V-shaped blocking plate 45 and staggered. In the process of rolling and impacting, the large stone will be further broken into small stones. Both sides of the multiple V-shaped blocking plates 45 have oblique blocking plates 46 and are staggered, so as to further extend the moving path and moving time of the large stone on the second inclined plate 33, so that the large stone is delayed from falling into the muck truck 6 before the soil. When the large stone falls into the muck truck 6, it directly contacts the soil, thereby avoiding the impact between the large stone and the muck truck 6, and the soil and small stones slide off the second inclined plate 33.It is conducive to the slow falling of soil and small stones into the muck truck 6, reducing the impact of soil and small stones on the muck truck 6, and extending the service life of the muck truck 6 and the track.

[0041] In summary, in the present invention, the soil and stones slide down through the inclined first inclined plate 31 to the buffer plate 322 which is initially in a horizontal state, the large stones remain in the buffer plate 322, the soil and small stones leak down through the through holes 326 to the inclined second inclined plate 33, the soil and small stones slide along the inclined plate into the muck truck 6, the soil and small stones that fall first are spread on the bottom of the muck truck 6, the buffer plate 322 rotates under the action of the stone's own gravity, the rotating shaft 321 and the buffer plate 322, both ends of the buffer plate 322 are connected to the first inclined plate 31 and the second inclined plate 33 after being buffered by the buffer connection part 34, so as to form a smooth conveying path, and the rotating shaft 321 and the buffer plate 322 rotate under the action of the stone's own gravity. While the shaft 321 rotates, the transmission mechanism 5 drives the blocking mechanism 4 to move upward perpendicularly to the second inclined plate 33, so that the blocking mechanism 4 prolongs the moving path and moving time of the large stone on the second inclined plate 33, so that the large stone falls into the muck truck 6 after the soil, and the large stone directly contacts the soil when falling into the muck truck 6, avoiding the impact of the large stone and the muck truck 6, and the soil and small stones slide down from the second inclined plate 33, which is conducive to the soil and small stones slowly falling into the muck truck 6, reducing the impact of the soil and small stones on the muck truck 6, extending the service life of the muck truck 6 and the track, and also reducing the splashing and scattering of stones and soil during the sliding process. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
