[0042] Buffer plate 305, the buffer plate 305 is a square plate structure, one side of the buffer plate 305 is fixedly connected with one side of the connecting block 304, the buffer plate 305 is used to drive the connecting block 304 and the rotating sleeve 303 to rotate on the outer wall of the fixed shaft 302 when impacted by bulk grain, and the buffer plate 305 is used to buffer and guide bulk grain.

[0043] Rotating sleeve 303, both sides of the rotating sleeve 303 are fixedly connected with torsional spring 306, one end of the torsional spring 306 is fixedly connected with limiting block 307, the inner wall of the limiting block 307 is fixedly connected with the outer wall of the fixed shaft 302, and the torsional spring 306 is used to reset the rotating sleeve 303.

[0044] Conveyor 2, the bottom of the conveyor 2 is fixedly connected with rotating shaft 310, the outer wall of the rotating shaft 310 is rotatably connected with roller 311, the top of the roller 311 is attached to the surface of the discharging mechanism 5, and the roller 311 is used to tighten the transmission of the discharging mechanism 5.

[0045] The outer wall of the roller 311 is provided with a magnetic groove 312, one side of the magnetic groove 312 is provided with a magnetic plate 309, and the side opposite to the magnetic plate 309 has magnetism and is attracted to the opposite pole.

[0046] The inner wall of the magnetic plate 309 is fixedly connected with a square plate 308, one side of the square plate 308 is fixedly connected with the outer wall of the rotating sleeve 303, the surface of the buffer plate 305 is provided with a long baffle 313, and the number of the long baffles 313 is two.

[0047] In use, when the discharging mechanism 5 in the conveyor 2 transmits the bulk grain to the right top, the bulk grain particles will be scattered and fallen down with continuous transmission, and the bulk grain particles are completed to be boxed through the flow guide falling of the buffer plate 305;

[0048] When the bulk grain falls on the buffer plate 305 and is scattered along the inclined surface of the buffer plate 305, the inclined buffer plate 305 buffers and slows down the bulk grain to a certain extent, avoids that the bulk grain directly falls from the discharging mechanism 5 to the inside of the box below and stays in the air for too long, causes the problem that the bulk grain is freely scattered in the air, completes the flow guide and buffering of the bulk grain through the buffer plate 305, and also reduces the problem that a large amount of splashing dust is caused by the bulk grain directly falling to the bottom of the box, avoids the loss problem caused in the bulk grain transportation and loading process;

[0049] Embodiment two: please refer to Figures 1-10 On the basis of embodiment one, the application provides a technical solution: the long plate is currently used to buffer and flow guide the bulk grain to prevent the bulk grain from being scattered and to ensure the stability of discharging. However, the existing flow guide structure has many problems:

[0050] On the one hand, when the transportation speed of the bulk grain through the discharging mechanism is fast and the bulk grain amount is large, the impact force on the flow guide structure increases, if the inclined surface cannot be automatically adjusted according to the change of the bulk grain amount, the buffering effect of the buffer plate on the bulk grain will be excessive, which affects the loading and transportation efficiency of the bulk grain, and at the same time, the flow guide structure cannot give enough discharging space to the bulk grain, so that the bulk grain is easy to accumulate at the flow guide structure, which affects the discharging effect;

[0051] On the other hand, in the bulk grain transportation process, if the bulk grain is wet inside, it is easy to adhere to the surface of the buffer plate, which causes slow discharging and affects the overall working efficiency;

[0052] Furthermore, the existing diversion structure has fixed structures on both sides and cannot automatically adjust its state according to changes in the amount of bulk grain discharged. When a large amount of material is discharged, it may hinder the sliding of the bulk grain, causing the bulk grain to be crowded and losing its diversion effect. However, when a small amount of material is discharged, it cannot effectively gather the bulk grain, causing it to float in the air. At the same time, the existing diversion structure has a large blocking area for the bulk grain, which affects the discharge speed of the bulk grain and cannot effectively separate and break up the bulk grain, causing the bulk grain to easily adhere and clump inside. Therefore, a diversion mechanism 4 is provided on the surface of the buffer plate 305. The diversion mechanism 4 includes a first rotating rod 401. The surface of the buffer plate 305 is rotatably connected to one end of the first rotating rod 401. The outer wall of the first rotating rod 401 is fixedly connected to one side of the long baffle 313. A pull rope 402 is fixedly connected to one side of the long baffle 313, and one end of the pull rope 402 is fixedly connected to the outer wall of the conveyor 2.

[0053] An elastic strip 403 is fixedly connected to one side of the long baffle 313, and the other end of the elastic strip 403 is fixedly connected to the guide plate 404. A second rotating rod 405 is fixedly connected to one side of the guide plate 404, and one end of the second rotating rod 405 is rotatably connected to the surface of the buffer plate 305. The elastic strip 403 is cone-shaped.

[0054] The long baffles 313 on the buffer plate 305 will block and guide the bulk grain on both sides to prevent the bulk grain from scattering. When the bulk grain is transported at a faster speed through the unloading mechanism 5, the amount of bulk grain dumped onto the buffer plate 305 is large, and the impact force on the buffer plate 305 increases, thereby driving the connecting block 304 and the rotating sleeve 303 to rotate and descend on the outer wall of the fixed shaft 302, and twisting the torsion spring 306 to deform it. As a result, the buffer plate 305 will open and close and rotate downward accordingly as the amount of bulk grain impacting it increases, making the inclined surface of the buffer plate 305 steeper. In this way, when transporting and loading bulk grain at high power, the buffering effect of the buffer plate 305 on a part of the bulk grain can be reduced, and more space for unloading of bulk grain can be provided. The buffer plate 305 can automatically and adaptively adjust its inclined surface according to the change of the different transport loads to ensure that it is more in line with its working state, and improve the loading and transportation efficiency of bulk grain as much as possible under the premise of ensuring stable diversion.

[0055] When the unloading mechanism 5 continuously transmits, it will drive the roller 311 that is attached thereto to rotate synchronously. The continuous rotation of the roller 311 will drive the magnetic plate 309 and the square plate 308 to oscillate up and down through the magnetic attraction force between the magnetic slot 312 in the inner wall and the magnetic plate 309. The oscillation of the square plate 308 will simultaneously affect the oscillation of the connecting block 304 and the buffer plate 305 up and down through the rotating sleeve 303. The self-vibration of the buffer plate 305 is realized through the reset of the torsional spring 306, so that the buffer plate 305 can prevent the problem of slow unloading caused by the adhesion of the internal moisture of the bulk grain to the surface of the buffer plate 305 through the continuous vibration of the buffer plate 305 under the buffer of the bulk grain flow guide;

[0056] When the buffer plate 305 is rotated and descended due to the impact of the bulk grain, it indicates that the impact force of the bulk grain is large, and the unloading state of the bulk grain falling amount is large. At this time, as the buffer plate 305 descends, the long baffle 313 on the buffer plate 305 will be pulled by the pull rope 402. Since the distance between one end of the rotating sleeve 303 and the pull rope 402 and the side connection of the conveyor 2 is far away after the buffer plate 305 is rotated and descended, the long baffle 313 will be pulled by the pull rope 402 to rotate to the both sides of the buffer plate 305 due to the descent of the buffer plate 305, so that the left and right long baffles 313 on the buffer plate 305 change from the V-shaped state to the mutually parallel state after being opened, so that the long baffles 313 in this state can automatically open the channel of the bulk grain falling on the buffer plate 305, so that the bulk grain can have a larger falling channel when a large amount of bulk grain is unloaded, so as to ensure that the bulk grain does not appear crowded and loses the path guiding effect of the long baffles 313 and the buffer plate 305, so that it can still ensure the stable unloading effect of being buffered by the buffer plate 305 and being limited and guided by the long baffles 313 under different unloading conditions. When a small amount of bulk grain falls, the more uniform and concentrated guiding and falling of the bulk grain is completed by the gathering distribution of the long baffles 313 and the flow guide plate 404, so as to gather the falling direction of the bulk grain as much as possible and prevent the problem of bulk grain floating in the air;

[0057] And the outward opening of the long baffle 313 will pull the elastic strip 403, so that the two guide plates 404 are synchronously pulled outward to the horizontal distribution state, so that the impact area of the long baffle 313 and the guide plate 404 is reduced when the bulk grain slides on the buffer plate 305, so that the bulk grain slides more smoothly on the buffer plate 305, and the elastic strip 403 is pulled flat, the bulk grain is separated and dispersed, the problem of adhesion and clumping of the bulk grain is reduced, and the vibration of the guide plate 404 and the long baffle 313 is realized, and the elastic strip 403 is repeatedly vibrated, so that the elastic strip 403 can still realize the effect of separating and dispersing the bulk grain while completing the reset of the guide plate 404 and the long baffle 313, thereby further improving the working efficiency of the bulk grain transportation and loading.

[0058] Example three: please refer to Figures 1-14 On the basis of example one and example two, the application provides a technical solution: the buffer plate 305 is used for buffering and guiding the bulk grain to prevent the bulk grain from scattering, when the bulk grain needs to be transported and loaded more, that is, the flow rate and flow of the bulk grain increase, the impact force on the buffer plate increases, and the rotation angle also deepens, which can easily cause the bulk grain to be crowded and accumulated at the buffer plate, and the height of the accumulation can overflow the long baffle 313 on both sides, thereby causing the bulk grain to scatter outward, and the bulk grain cannot be stably located between the two long baffles 313 and the buffer plate 305 under different flow rates and flow, which seriously affects the stability and efficiency of the bulk grain transportation and loading process, and increases the risk of bulk grain scattering, therefore, the surface of the buffer plate 305 is provided with a discharging mechanism 5, the discharging mechanism 5 includes a sliding plate 501, the sliding plate 501 is slidingly connected to the inner wall of the buffer plate 305, one side of the sliding plate 501 is fixedly connected with a first magnetic block 502, one side of the first magnetic block 502 is in contact with a second magnetic block 503, the top of the second magnetic block 503 is fixedly connected with the bottom of the buffer plate 305, one side of the first magnetic block 502 is fixedly connected with a long strip block 505 through an elastic rope 504, the top of the long strip block 505 is fixedly connected with the bottom of the buffer plate 305, and the second magnetic block 503 and the first magnetic block 502 have magnetism on the opposite side and are opposite poles.

[0059] If more unloading transportation loading is needed for the bulk grain, the impact force on the buffer plate 305 will continue to increase, and the rotation angle of the buffer plate 305 will also deepen, until the buffer plate 305 rotates to the preset angle, at which time the counterweight of the sliding plate 501 on the buffer plate 305 is greater than the magnetic attraction force between the first magnetic block 502 and the second magnetic block 503, so that the sliding plate 501 quickly slides in the inner wall of the buffer plate 305, and pulls the elastic rope 504 to deform, thereby opening the opening below the buffer plate 305 to increase the unloading channel for the bulk grain, so that there is enough falling space under the condition of a large amount of bulk grain impact falling, and the problem of bulk grain overflowing the two long baffles 313 and scattering outward can be avoided, so as to ensure that the bulk grain at different flow rates and flow rates can stably fall between the two long baffles 313 and the buffer plate 305, thereby avoiding the problem of bulk grain scattering and drifting during transportation and loading.

[0060] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
