[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0056] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0057] like Figure 1-8 As shown, this utility model provides an intelligent grain unloader, which includes a frame 1, a grain unloader loading chamber 2, a grain suction hood 3, a shock-absorbing connecting frame 4, a first conveyor 5, a second conveyor 6, a steering mechanism 7, and an extension frame 8.
[0058] The feeding hopper 2 of the grain unloader is mounted on the frame 1. The feed end of the feeding hopper 2 is hinged to the rotating shaft via an angle adjustment shaft 22. The main function of the feeding hopper is to receive grain and feed it into the suction hood 3. Its connection to the frame 1 and the design of the angle adjustment shaft 22 allow the feeding hopper to flexibly adjust its angle to adapt to different working environments. The suction hood 3 is located at the end of the feeding hopper 2 and contains a spiral cutter shaft and a feeding scraper. The spiral cutter shaft inside the suction hood 3 is responsible for conveying the grain from the feed end to the feeding scraper, which then progressively transports the grain to the next conveying area. The design of the suction hood 3 helps to effectively transmit power and reduce grain loss.
[0059] In this invention, the shock-absorbing connecting frame 4 includes a fixed frame 41 and a shock-absorbing shell 42. One side of the connecting frame is fitted against the grain suction hood 3. The top end of the shock-absorbing shell 42 is fixedly connected to the top end of the connecting frame, and the bottom end of the shock-absorbing shell 42 is connected to the grain suction hood 3, which is used to reduce the impact of vibration. The shock-absorbing spring 13 inside the shock-absorbing shell 42 can effectively absorb vibration and reduce its impact on the system, especially on the feeding hopper and the grain suction hood 3, ensuring stable operation of the equipment.
[0060] In this invention, one end of the first conveyor 5 is located below the discharge end of the grain unloader's loading hopper 2, and one end of the first conveyor 5 is movably connected to the frame 1; the sloping feed end of the second conveyor 6 is located below the discharge end of the first conveyor 5. These conveyors are used to transport grain from one section to another. The adjustable connection of the first conveyor 5 and the design of the second conveyor 6 allow the equipment to adapt to different slopes and conveying space sizes. The design of the steering mechanism 7 between the sloping feed end of the second conveyor 6 and the discharge end of the first conveyor 5 also increases the system's flexibility, allowing it to turn to adapt to conveying in different directions; the steering mechanism 7 is located between the sloping feed end of the second conveyor 6 and the discharge end of the first conveyor 5; the steering mechanism 7, through the cooperation of components such as the unloading hopper 71, the clamping plate 72, and the connecting shaft 73, enables the second conveyor 6 to turn and adjust the conveying direction. The design allows the system to work flexibly in narrow spaces and facilitates adjustment of the grain conveying direction.
[0061] In this invention, the extension frame 8 is a triangular frame structure. The extension frame 8 is installed at the port of the gentle slope end of the second conveyor 6. The free end of the extension frame 8 is provided with a hinge interface for connecting a steerable vehicle. The function of the extension frame 8 is to steer the entire second conveyor 6 by steering the vehicle, thereby adapting to narrower spaces and changing the conveying direction when necessary. The hinge interface design makes the connection more stable, ensuring that it will not loosen during steering.
[0062] In this utility model, the steering mechanism 7 includes a discharge hopper 71, a clamping plate 72, a connecting shaft 73, and a roller connecting shell 74. The discharge hopper 71 is located below the discharge end of the first conveyor 5. The top surface of the clamping plate 72 is rotatably sleeved on the discharge port at the bottom of the discharge hopper 71. The connecting shaft 73 is sleeved on the discharge port at the bottom of the discharge hopper 71. The clamping plate 72 is located above the connecting shaft 73. The top surface of the roller connecting shell 74 is fixedly connected to the bottom surface of the clamping plate 72. The bottom surface of the roller connecting shell 74 is slidably connected to both sides of the second conveyor 6. The roller connecting shell 74 is inverted U-shaped.
[0063] In this utility model, the bottom surface of the sealing shell 9 is integrally formed with the unloading hopper 71, and one side of the sealing shell 9 is sleeved on the unloading end of the first conveyor 5. The feeding shell 10 has a cylindrical structure and is located inside the roller connecting shell 74. The top of the feeding shell 10 is located directly below the unloading hopper 71, and the bottom surface of the feeding shell 10 faces the conveyor belt of the second conveyor 6. An arc-shaped opening 11 is provided on the side wall of the feeding shell 10. The opening direction of the arc-shaped opening 11 is facing the uphill direction of the conveyor belt of the second conveyor 6.
[0064] In this invention, the first sliding member 12 is disposed inside the shock-absorbing shell 42. The two ends of the first sliding member 12 are a wide edge 121 and a first oblique end 122. The wide edge 121 is wider than the first oblique end 122, and the first oblique end 122 is located on the axis of symmetry of the wide edge 121. The wide edge 121 is a radially protruding rectangular structure, and its diameter is larger than the outer diameter of the shock-absorbing spring 13, forcing vibration energy to be converted into spring compression potential energy. The two sides of the wide edge 121 symmetrically abut one end of each of the two shock-absorbing springs 13. The design of the shock-absorbing springs 13 and the sliding member is mainly to reduce mechanical vibration and avoid interference with grain conveying. Through the sliding of the first sliding member 12 and the compression of the shock-absorbing springs 13, system vibration can be effectively reduced, making the conveying more stable. The number of flanges 14 corresponds to the number of wide flanges 121. The flanges 14 are respectively set on the inner walls of both sides of the shock-absorbing shell 42. The other end of the shock-absorbing spring 13 is connected to the flange 14. The second sliding member 15 is slidably set in the extension direction of the first oblique end 122. The second sliding member 15 includes a second oblique end 151 and a connecting end 152. The connecting end 152 is fixedly connected to the connecting rod 16. The second oblique end 151 and the first oblique end 122 have the same inclination direction. One end of the connecting rod 16 is fixedly connected to the second sliding member 15. The other end of the connecting rod 16 passes through the shock-absorbing shell 42 and is fixedly connected to the grain suction cover 3. The unloading wheel 17 is located between the second oblique end 151 and the first oblique end 122. The side wheel surface of the unloading wheel 17 is in contact with the oblique surfaces of the second oblique end 151 and the first oblique end 122.
[0065] In this invention, two sets of rollers 18 are provided, respectively distributed on the inner walls of both sides of the roller connecting shell 74. The wheel surfaces of the rollers 18 contact the tops of the frames 1 on both sides of the second conveyor 6, allowing the roller connecting shell 74 to slide along the slope direction of the frame 1 of the second conveyor 6. The design of the rollers 18 enables the roller connecting shell 74 to slide along the frame 1 of the second conveyor 6, while the locking wheels 20 slide in the slide rail 19, ensuring smooth movement between the rollers 18 and the frame 1. This design ensures the stability and flexibility of the machine during operation. The slide rail 19 is located on one side of the frames 1 on both sides of the second conveyor 6, and the number of locking wheels 20 corresponds to the number of rollers 18. The locking wheels 20 are located below the rollers 18 and are embedded in the slide rail 19.
[0066] In this invention, the support frame 21 is vertically fixed to the machine frame 1, and the angle adjustment shaft 22 is laterally movably installed on the top of the support frame 21. Two lifting cylinders 23 are provided, respectively mounted on both sides of the grain unloader's loading chamber 2. One end of each lifting cylinder 23 is installed on the machine frame 1, and the output end of the lifting cylinder 23 is connected to the loading chamber of the connecting frame. The design of the lifting cylinders 23 and the angle adjustment shaft 22 allows the grain unloader to operate at different heights and angles, enhancing the equipment's adaptability and enabling adjustments according to the working environment.
[0067] It should be noted that, in use, the intelligent grain unloader designed in this utility model is activated by popping out the output end of the lifting cylinder 23 to lift the grain unloader's loading chamber 2. The inlet end of the grain unloader's loading chamber 2 will be raised at an angle around the rotating shaft 3. After being raised to a suitable height, the grain unloader's loading chamber 2 can be activated. The spiral cutter shaft inside the grain unloader's suction hood 3 will then transport the grain to the loading scraper in the center of the suction hood 3. The loading scraper climbs step by step, driving the grain transport. During the grain conveying process, the motor will generate vibrations, which will first be transmitted to the shock-absorbing connecting frame. After receiving the vibration, the first sliding member 12 in the shock-absorbing shell 42 of the shock-absorbing connecting frame 4 will slide inside the shock-absorbing shell 42. During the sliding process, the wide edge 121 of the first sliding member 12 will squeeze the two shock-absorbing springs 13. The compression and rebound of the springs will consume some of the vibration. The first oblique end 122 of the first sliding member 12 will squeeze the unloading wheel 17 in contact with itself during the sliding process. The unloading wheel 17 rolls obliquely towards the other second oblique end 151 in contact with its own side wheel surface, thereby blocking the vibration transmission. Finally, when the second oblique end 151 drives the second sliding member 15 and the connecting rod 16 to exert force on the end of the grain unloader's loading chamber 2, the impact of vibration on the grain suction hood 3 at the end of the loading chamber has been significantly reduced. In this way, the spiral cutter shaft of the grain suction hood 3 will run smoothly, thereby improving the loading efficiency. If the conveying space is narrow, simply connect the hinge interface of the extension frame 8 to a steerable vehicle, and then use the vehicle's steering to drive the extension frame 8. This, in turn, drives one end of the entire second conveyor 62 to turn. After turning, grain can be conveyed to the storage equipment in the other direction. During the turning process, the snap-fit plate 72 at the top of the roller connecting shell 74 will rotate around the bottom discharge port of the fitted unloading hopper, thus driving the entire second conveyor 6 to turn around the unloading hopper. During unloading, if the unloading space is narrow, the first conveyor 5 can be directly pushed by the grain unloader. The discharge end pushes the discharge hopper 71, and the discharge hopper 7131 drives the clamping plate 72 through the connecting shaft 73 at the bottom discharge port, which in turn drives the roller connecting shell 74 connected to the bottom of the clamping plate 72. Since the rollers 18 movably arranged on the inner walls of the two sides of the roller connecting shell 7434 are slidably connected to the frame 1 on both sides of the second conveyor 6, the rollers 18 slide on the frame 1, which allows the discharge end of the first conveyor 5, together with the steering mechanism 7, to slide to any slope position of the frame 1 of the second conveyor 6. The space occupied by the two conveyors will be folded to a certain extent to adapt to a narrower conveying space.
[0068] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
