[0024] Preferably, the upper flange of the rotary support is fixedly connected to the connecting baffle. At least two rotating blocks are provided near the bottom inside the upper flange of the rotary support. The rotating blocks are arranged in an arc structure. An annular baffle is arranged above the rotating blocks. The baffle is perpendicular to the rotating blocks. The purpose of setting the baffle is to prevent bulk materials from entering above the corrugated pipe and prevent the corrugated pipe from being damaged. And when the rotating block moves towards the sealing plate, it can play a guiding role for its vertical movement; a sealing plate is arranged inside the rotating block. The sealing plate is connected to the inner wall of the upper flange of the rotary support in an annular structure. The sealing plate and the upper flange of the rotary support form a sealing cavity. A corrugated pipe is connected to the inner side of the rotating block close to the sealing plate. The corrugated pipe is made of metal. A plurality of moving rods are connected to one side of the rotating block close to the sealing plate. The moving rods are arranged in through grooves opened in the sealing plate.

Meeting the above conditions, the concave block can slide relative to the ball when in contact with the ball. If the groove length is too long, it will cover a plurality of balls and affect the sliding efficiency. If the groove length is too short, it is not enough to cover a plurality of single balls, and the contact area between the groove and the ball is small, which will affect the relative sliding effect.

[0025] Preferably, a protective cover is provided at one end of the material taking and conveying mechanism close to the material taking mechanism. The protective cover is provided with a flange combination and is connected to the side plate of the material taking and conveying mechanism through the flange combination. A material taking shovel plate is provided at the end of the protective cover. The material taking shovel plate extends out of the outer end of the material taking and conveying mechanism.

An upper idler one is arranged on the upper idler bracket. A lower idler bracket corresponding to the upper idler bracket is provided. A lower idler one is arranged on the lower idler bracket.

The support steel plate strengthens the support for the side plate and the idler bracket.

[0026] Preferably, a flange plate assembly is provided at one end of the feeding and conveying mechanism close to the second electric roller, and is connected to the connecting baffle through the flange plate assembly. The second electric roller is provided with a roller bracket, and a reinforcing plate is connected to the end of the roller bracket away from the second electric roller.

[0027] In addition, when the loading machine is in use, the telescopic support member is adjusted through the hydraulic control system to adjust the loading height. The bulk materials are automatically rolled into the internal part of the feeding and conveying mechanism through the feeding blades of the material taking mechanism. The material taking mechanism conveys the materials to the feeding and conveying mechanism, and the feeding and conveying mechanism evenly sends the materials into the carriage through the discharging mechanism; when the bulk materials near the material taking mechanism are loaded, there is no need to move the loading machine. Only the material taking driving member needs to be operated. The material taking driving member can adopt a hydraulic cylinder. The hydraulic control system drives the hydraulic cylinder to extend, driving the material taking and conveying mechanism to slide relatively on the guiding slide rod through the guiding wheel. The material taking and conveying mechanism extends relative to the feeding and conveying mechanism. And through the setting of the trapezoidal structure at the end of the material taking and conveying mechanism, it can prevent the material taking and conveying mechanism from cutting the ground when moving, affecting the normal propulsion and movement of the material taking and conveying mechanism; a sealing structure is arranged at the discharging end of the material taking and conveying mechanism. The sealing structure is arranged in a surrounding shape at one end of the first electric roller, preventing the bulk materials from splashing everywhere when contacting the conveyor belt of the feeding and conveying mechanism. Through the above settings, by moving the material taking and conveying mechanism, it is possible to avoid frequently moving the loading machine during the loading process, which not only improves the loading efficiency and saves the loading time. During loading, only by pushing the material taking combination forward can the material taking be completed. In this way, the walking chassis does not need to move during the loading process. The advantage is that the freight vehicle does not need to move, and the material taking combination can complete the material taking action with less energy consumption without starting a large-power crawler chassis.

[0028] When the bulk materials are fed into the discharging mechanism through the feeding and conveying mechanism, the discharging mechanism is arranged to feed the materials into the carriage in a rotating and moving manner. The materials enter the blanking cavity through the connecting baffle, and are fed into the moving belt conveyor through the blanking cavity. When loading the vehicle, vehicles can be parked in advance on both sides of the moving belt conveyor. By rotating the moving belt conveyor, one side of the moving belt conveyor can be aligned with one of the vehicles for loading. During the loading process, if one place is filled, the driving servo motor indirectly drives the moving belt conveyor to rotate, which can effectively prevent frequent movement of the vehicle during loading, reduce the number of vehicle movements, thereby improving the loading efficiency and enhancing the uniformity of loading. When one vehicle is filled, the discharging end of the moving belt conveyor is rotated above the carriage of the other vehicle on the other side to continue loading the other vehicle, enabling rapid loading of two vehicles. When loading the vehicle, after the freight vehicle stops under the cloth conveyor, the cloth conveyor can be rotated to align the cloth conveyor with the carriage of the freight vehicle, and the materials can be evenly loaded onto the freight vehicle by horizontally moving the cloth conveyor.

[0029] Preferably, the material taking and conveying device can be a belt conveyor or a scraper conveyor.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] A bulk material loading machine of the present invention can avoid frequent movement of the loading machine during the loading process through the moving material taking and conveying mechanism, not only improving the loading efficiency and saving the loading time. During loading, only by pushing the material taking combination forward can the material be taken. In this way, the walking chassis does not need to move during the loading process. The advantage is that the freight vehicle does not need to move, and the material taking combination can complete the material taking action with relatively small energy consumption without starting a large-power crawler chassis.

[0032] During the loading process, if one place in the carriage is filled, the driving servo motor indirectly drives the moving belt conveyor to rotate, which can effectively prevent frequent movement of the vehicle during loading, reduce the number of vehicle movements, thereby improving the loading efficiency and enhancing the uniformity of loading. When one vehicle is filled, the discharging end of the moving belt conveyor is rotated above the carriage of the other vehicle on the other side to continue loading the other vehicle, enabling rapid loading of two vehicles.

If the groove length is too long, it will cover a plurality of balls 631 and affect the sliding efficiency. If the groove length is too short, it is not enough to cover a plurality of single balls 631, and the contact area between the groove and the balls 631 is small, which will affect the relative sliding effect.

[0065] When the bulk material enters the feeding cavity of the discharging mechanism through the feeding conveyor mechanism and then falls into the moving belt conveyor through the feeding cavity, if the feeding speed of the feeding conveyor is too fast or the moving conveyor fails to feed in time when the material passes through the feeding cavity, it will cause the bulk material to accumulate in the feeding cavity. Once the accumulation occurs and the bridging effect takes place, even if the moving belt conveyor continues to work, due to the bridging effect, the bulk material will not come into contact with the moving belt conveyor, resulting in the inability of the moving belt conveyor to transport the material. The equipment needs to be stopped for maintenance and dredging, and the operation efficiency of the equipment is low. By providing two or more arc-shaped rotating blocks at a position near the bottom inside the feeding cavity, the rotating blocks slide circumferentially along the sealing plate in the through groove of the sealing plate through the arranged moving rods, and the sealing plate is of an annular structure. When the bridging effect occurs at the bottom inside the feeding cavity (it should be understood that the bridging effect is caused by the accumulation from the bottom); as the material in the feeding cavity gradually accumulates, the gravity received by the bottom of the accumulated material gradually increases, and the vertical separation of the bulk material from the rotating block also gradually increases, making the bridging effect more obvious. Since the vertical force on the rotating block increases, the corrugated pipe is compressed, and it can prevent the material from entering the inside of the moving block, playing a sealing role; the moving rod drives the compression spring, and when the spring is compressed to the limit, it continues to drive the concave block to move. When the concave block comes into contact with the ball, the concave block contacts the ball. The relationship between the groove length L of the concave block and the diameter R of the ball, and at the same time, due to the annular layout of the balls, the component force of the pressure of the concave block on the ball will cause the ball to rotate, and there is a slight relative movement between the ball and the concave block. As the concave block moves, and due to the limiting effect of the ball, the concave block makes a circular motion, and synchronously through the compressed spring, the moving rod and the rotating block act on the accumulated bulk material in the opposite direction, generating a rotational force in the horizontal direction on the bulk material, playing a role in dispersing the bulk material, thereby effectively alleviating the bridging effect and avoiding the blockage problem of the feeding cavity to a certain extent. It should be understood that most of the bulk material is small stone particles. When the bridging effect occurs to the small stone particles, even if the rotating block makes a slight rotation on the periphery of the bridge, it will break the balance force between the small stone particles, thereby alleviating the bridging effect. In the actual use process, the rotating block will not make a large rotation; when the bridging effect is solved, the rotating block automatically resets through the resilience of the spring.

[0066] One end of the material fetching and conveying mechanism close to the material fetching mechanism 4 is provided with a protective cover 312. The protective cover 312 is provided with a flange assembly 311, and is connected to the side plate 34 of the material fetching and conveying mechanism through the flange assembly 311. The end of the protective cover 312 is provided with a material fetching shovel plate 310. The material fetching shovel plate 310 extends out of the outer end of the material fetching and conveying mechanism. The material fetching shovel plate 310 is arranged below the material fetching mechanism 4. The material fetching mechanism 4 is inclined to prevent the material fetching mechanism 4 from shoveling the bulk materials to the bottom of the material fetching and conveying mechanism during the feeding process, resulting in the leakage of materials from the bottom of the material fetching and conveying mechanism and affecting the feeding efficiency. The material fetching and conveying mechanism is provided with an upper idler bracket 313. An upper idler 319 is arranged on the upper idler bracket 313. A corresponding lower idler bracket is arranged for the upper idler bracket 313. A lower idler 321 is arranged on the lower idler bracket. The upper idler 319 and the lower idler 321 support the belt 320, and the belt 320 is driven by an electric roller 31. A support steel plate 318 is arranged inside the side plate 34, and the support steel plate 318 strengthens the support for the side plate 34 and the idler bracket.

[0067] One end of the feeding and conveying mechanism 2 close to the electric roller 21 is provided with a flange plate assembly 22, and is connected to the connecting baffle 61 through the flange plate assembly 22. The electric roller 21 is provided with a roller bracket 23. One end of the roller bracket 23 far from the electric roller 21 is connected with a reinforcing plate 25. The reinforcing plate 25 is arranged inside the side support plate 213. One end of the feeding and conveying mechanism 2 far from the electric roller 21 is provided with a redirecting roller 27. A conveyor belt 24 is arranged between the redirecting roller 27 and the electric roller 21. The conveyor belt 24 is provided with an upper idler 29 and a lower idler. The upper idler 29 is arranged on the upper idler frame 28, and the lower idler is arranged on the lower idler bracket. A plurality of reinforcing steel pipes are arranged inside the fixing plate 211. The redirecting roller 27 is connected with a tensioning member 26, and the tensioning member 26 is a combination of a threaded rod and a spring.

[0068] Specifically, when this loading machine is in use, the telescopic support member 7 is adjusted through the hydraulic control system to adjust the loading height. Through the feeding blades 44 of the material taking mechanism 4, the bulk materials are automatically rolled into the material taking and conveying mechanism. The material taking and conveying mechanism conveys the materials to the feeding and conveying mechanism 2, and the feeding and conveying mechanism 2 evenly sends the materials into the carriage through the discharging mechanism 6. When the bulk materials near the material taking mechanism 4 are loaded, there is no need to move the loading machine. Only need to operate the material taking driving member 5. The material taking driving member 5 can adopt a hydraulic cylinder. The hydraulic control system drives the hydraulic cylinder to extend, driving the material taking and conveying mechanism to slide relatively on the guiding slide rod 212 through the guiding wheel 37. The material taking and conveying mechanism extends relative to the feeding and conveying mechanism 2. And through the setting of the trapezoidal structure at the end of the material taking and conveying mechanism, it can prevent the material taking and conveying mechanism from cutting the ground during movement, affecting the normal advancement and movement of the material taking and conveying mechanism. A sealing structure is arranged at the discharging end of the material taking and conveying mechanism. The sealing structure is arranged in a surrounding shape at one end of the electric roller 31, preventing the bulk materials from splashing everywhere when contacting the conveyor belt 24 of the feeding and conveying mechanism 2. Through the above settings, by moving the material taking and conveying mechanism, it is possible to avoid frequently moving the loading machine during the loading process, not only improving the loading efficiency and saving the loading time. During loading, only need to push the material taking combination forward to complete the material taking. In this way, the walking chassis does not need to move during the loading process. The advantage is that the transport vehicle does not need to move, and the material taking combination can complete the material taking action with less energy consumption, without starting the large-power crawler chassis 1.

[0069] When the bulk materials are sent into the discharging mechanism 6 through the feeding and conveying mechanism 2, the discharging mechanism 6 is set to send the materials into the carriage in a rotating and moving manner. The materials enter the blanking cavity 67 through the connecting baffle 61 and are sent into the mobile belt conveyor 612 through the blanking cavity 67. During loading, vehicles can be parked in advance on both sides of the mobile belt conveyor 612. By rotating the mobile belt conveyor 612, one side of the mobile belt conveyor 612 is aligned with one of the vehicles for loading. During the loading process, if one place is full, the driving servo motor 64 indirectly drives the mobile belt conveyor 612 to rotate, which can effectively prevent the vehicle from moving frequently during the loading process, reduce the number of vehicle movements, thereby improving the loading efficiency and enhancing the evenness of loading. When one of the vehicles is full, the discharging end of the mobile belt conveyor 612 is rotated above the carriage of the other vehicle to continue loading the other vehicle, enabling rapid loading of two vehicles. During loading, after the transport vehicle stops under the cloth conveyor, the cloth conveyor can be rotated to align the cloth conveyor with the carriage of the transport vehicle, and the materials can be evenly loaded on the transport vehicle by horizontally moving the cloth conveyor.

[0070] Preferably, the material taking and conveying device can be a belt conveyor or a scraper conveyor.
