[0040] Example 1: Please refer to Figure 1 , Figure 3 As shown, the present invention is a lifting type corn harvester grain bin structure, including a bin body 1 and a discharge mechanism 2, the discharge mechanism 2 includes a base 21 and a lifting drive member, one side of the top of the base 21 is fixedly installed with a bracket 22 arranged to be tilted outward, the top of the bracket 22 is rotatably connected to one side of the upper end of the bin body 1, the lifting drive assembly can drive the bin body 1 to move up and down on the base 21, and when the bin body 1 rises, it can rotate and move synchronously with the top of the bracket 22 as a fulcrum, so that the bin mouth position of the bin body 1 is rotated and tilted downward; an auxiliary support mechanism 3 is installed on the bracket 22, and the auxiliary support mechanism 3 includes The foldable support frame includes a rotation drive assembly and a foldable support frame. The foldable support frame is tightly arranged on the inclined surface of the outer surface of the bracket 22. The rotation drive assembly can drive the foldable support frame to rotate and adjust to a vertical state during the upward rotation of the warehouse body 1, and at the same time, the foldable support frame is unfolded and extended so that the bottom end of the foldable support frame can be supported on the ground; a limited locking mechanism 4 is also installed between the bracket 22 and the foldable support frame. The limited locking mechanism 4 can limit the foldable support frame when the foldable support frame is retracted and folded to one side of the bracket 22, and can unlock the foldable support frame when it is rotated and unfolded;

[0041] Specifically, the lifting type corn harvester grain bin structure in the present embodiment is installed on the rear side of the corn harvester, and is used to store the corn harvested by the corn harvester. When the bin body 1 is full of harvested corn, the corn harvester stops harvesting and moves the transfer vehicle to one side of the corn harvester, so that the cargo box of the transfer vehicle is located on one side of the bin body 1. Then, the bin body 1 is driven to lift upward on the base 21 by the lifting drive assembly. At the same time, during the lifting process, the bin body 1 rotates toward the side of the transfer vehicle with the top of the bracket 22 as the fulcrum, so that the bin mouth position of the bin body 1 gradually rotates and tilts downward and toward the cargo box of the transfer vehicle, so that the corn in the bin body 1 can be directly dumped and unloaded into the cargo box of the transfer vehicle; and during the lifting and rotation process of the bin body 1 , the rotary drive assembly drives the foldable support frame to gradually rotate and adjust to a vertical state at the outer end of the top of the bracket 22, at which time the limit locking mechanism 4 releases the lock of the foldable support frame, and then the foldable support frame is synchronously unfolded and extended downward during the rotation in the vertical direction, so that the bottom end of the foldable support frame can be supported on the ground, thereby auxiliary support for the top of the bracket 22 is provided by the foldable support frame; and when the unloading is completed, the warehouse body 1 is driven by the lifting drive assembly to flip downward and reset along the bracket 22, so that the warehouse body 1 is supported and placed on the top surface of the base 21 again, and at the same time, the rotary drive assembly drives the foldable support frame to refold and fit tightly against one side of the bracket 22, and the foldable support frame is limited and locked by the limit locking mechanism 4;

[0042] In this embodiment, the corn in the bin body 1 can be directly dumped and unloaded into the transfer vehicle located on one side of the corn harvester, which not only makes the unloading process of the corn harvester granary more convenient and quick, reduces the time required for unloading, and is beneficial to improving the working efficiency of the corn harvester, but also makes the subsequent transportation process of the corn more convenient by lifting the granary and directly unloading the corn into the transfer vehicle; the top of the bracket 22 is auxiliary supported by the foldable support frame to prevent the bracket 22 from being deformed and damaged due to excessive load during unloading, which is beneficial to improving the service life of the bracket 22; and when the granary is lifted to unload, its center of gravity will shift to one side of the unloading. Through the auxiliary support of the foldable support frame, the stability of the granary and the corn harvester during unloading can be improved, and the corn harvester can be prevented from tipping over due to the shift of the center of gravity; the foldable support frame is limit-locked by the limit locking mechanism 4, which can prevent the foldable support frame from shaking and colliding when the corn harvester is driving, which is beneficial to improving the stability and service life of the foldable support frame installed on the bracket 22.

[0043] Example 2: Please refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, the difference between this embodiment and the above embodiment is that a support rod 24 is rotatably mounted on the top of the bracket 22, and the outer edge surface of the upper end of the warehouse body 1 is fixedly connected to the support rod 24 through a connecting block; the lifting drive member is a hydraulic telescopic shaft 23, the bottom end of the hydraulic telescopic shaft 23 is rotatably connected to the bracket 22, and the telescopic end of the upper part of the hydraulic telescopic shaft 23 is rotatably connected to the side wall of the warehouse body 1;

[0044] When it is necessary to lift the silo 1 and flip it over for unloading, the silo 1 is pushed and lifted upward by controlling the extension of the hydraulic telescopic shaft 23. At the same time, the silo 1 drives the support rod 24 to rotate and flips toward the outside of the bracket 22 with the support rod 24 as a fulcrum, so that the opening of the silo 1 gradually flips downward, and the corn in the silo 1 is dumped outward through the opening for unloading.

[0045] Example 3: Please refer to Figure 3-Figure 8As shown, the difference between this embodiment and the above embodiment is that the foldable support frame includes a rotating shaft 314 and a folding drive member, the rotating shaft 314 is rotatably mounted on the upper end of the bracket 22, one end of the rotating shaft 314 is fixedly mounted with an upper support rod 31, and the bottom end of the upper support rod 31 is rotatably mounted with a lower support rod 32 through the folding drive member; the rotating drive assembly includes a transmission gear 311 and a driven gear 312, the transmission gear 311 is fixedly mounted on the end of the support rod 24, and the driven gear 312 is fixedly mounted on One end of the rotating shaft 314, and the transmission gear 311 is meshed and connected with the driven gear 312; the folding driving member includes a connecting rod 310 and a connecting plate 313, the connecting plate 313 is an L-shaped plate structure, the middle turning point of the connecting plate 313 is rotatably connected to the bottom end of the upper support rod 31, one end of the connecting plate 313 is rotatably connected to the end of the lower support rod 32, the other end of the connecting plate 313 is rotatably connected to the bottom end of the connecting rod 310, and the top end of the connecting rod 310 is rotatably installed on the upper end of the bracket 22;

[0046] Specifically, when the warehouse body 1 is lifted and flipped upward and drives the support rod 24 to rotate, the support rod 24 drives the transmission gear 311 to rotate synchronously. At this time, the transmission gear 311 engages to drive the driven gear 312 to rotate, and when the driven gear 312 rotates, it drives the upper support rod 31 to rotate outward through the rotating shaft 314, so that the upper support rod 31 gradually rotates from an inclined state to a vertical state, and at this time, the upper support rod 31 drives the connecting plate 313 and the lower support rod 32 to move outward synchronously, and the connecting plate 313 drives the lower end of the connecting rod 310 outward during the outward movement. When the upper and lower supports 31 are moved, the connection point between the middle of the connecting plate 313 and the upper support rod 31 is gradually staggered from the connecting rod 310, so that the connecting rod 310 pulls the connecting plate 313 to rotate, and at the same time, the connecting plate 313 drives the lower support rod 32 to gradually rotate and unfold on one side of the upper support rod 31, so that when the upper support rod 31 is rotated to a vertical state, the lower support rod 32 rotates 180 degrees relative to the upper support rod 31 and is also adjusted to a vertical state, so that the foldable support frame can be extended to support the ground, and the bracket 22 is auxiliary supported when the warehouse body 1 is unloading;

[0047] When the bin body 1 has completed unloading and is flipped downward to reset, the support rod 24 drives the transmission gear 311 to rotate in the opposite direction. At this time, the transmission gear 311 engages and drives the driven gear 312 to rotate in the opposite direction. When the driven gear 312 rotates in the opposite direction, it drives the upper support rod 31 to rotate inward and reset through the rotating shaft 314, so that the upper support rod 31 gradually rotates from a vertical state to an inclined state and is close to one side of the bracket 22. At the same time, the connecting rod 310 pushes the connecting plate 313 to rotate and reset, so that the connecting plate 313 drives the lower support rod 32 to gradually rotate and reset on one side of the upper support rod 31, thereby restoring the upper support rod 31 and the lower support rod 32 to a folded state.

[0048] Furthermore, the connecting rod 310 includes an upper connecting rod 3101, a connecting spring 3102 and a lower connecting rod 3103. The top end of the upper connecting rod 3101 is rotatably mounted on the upper end of the bracket 22, and the bottom end of the lower connecting rod 3103 is rotatably mounted on one end of the connecting plate 313. A connecting spring 3102 is fixedly installed between the upper connecting rod 3101 and the lower connecting rod 3103. By configuring the connecting rod 310 to be an elastic telescopic rod structure composed of an upper connecting rod 3101, a connecting spring 3102 and a lower connecting rod 3103, the connecting rod 310, the upper support rod 31 and the connecting plate 313 can be prevented from locking with each other, thereby ensuring that the connecting rod 310, the upper support rod 31 and the connecting plate 313 can rotate and move normally.

[0049] The foldable support frame 32 is provided with a plurality of foldable support members 37, each of which is provided with a plurality of foldable support members 37. The foldable support frame 32 is provided with a plurality of foldable support members 37, each of which is provided with a plurality of foldable support members 37.

[0050] Furthermore, a limit baffle 38 is fixedly installed on the back side of the hinged end of the lower support rod 32, and one end of the limit baffle 38 extends to the outside of the end of the lower support rod 32, and a limit socket 39 that can engage with the limit baffle 38 is fixedly installed on the back side of the bottom end of the upper support rod 31. When the lower support rod 32 is unfolded into a straight line relative to the upper support rod 31, the limit baffle 38 on the back side of the lower support rod 32 abuts against the back side of the upper support rod 31 and is engaged in the limit socket 39, so that the lower support rod 32 can be rotated by the limit baffle 38 and the limit socket 39 to prevent the lower support rod 32 from rotating excessively, thereby ensuring that the lower support rod 32 is in a straight line with the upper support rod 31 after rotation, thereby improving the stability of the lower support rod 32 when supporting.

[0051] Example 4: Please refer to Figure 1 , Figure 2 , Fig. 9 , Fig.10As shown, the difference between this embodiment and the above embodiment is that the limit locking mechanism 4 includes a clamp seat 42, the clamp seat 42 is fixedly mounted on the upper end of the upper support rod 31, an opening and closing driving assembly is installed inside the clamp seat 42, and telescopic slide bars 49 that are transmission-connected to the opening and closing driving assembly are slidably mounted on both ends of the clamp seat 42, and clamp blocks 41 are installed on the outer ends of the telescopic slide bars 49 at both ends, and the two clamp blocks 41 can be opened and closed under the drive of the opening and closing driving assembly, and the two clamp blocks 41 can be clamped on the surface of the threaded sleeve 33 when they are closed;

[0052] The opening and closing drive assembly includes a limit stopper 43, a slider 47 and a plurality of guide shafts 410. The slider 47 is slidably mounted inside the clamp seat 42. A V-shaped guide groove 48 is provided on the top surface of the slider 47. The plurality of guide shafts 410 are respectively fixedly mounted on the inner side ends of the corresponding telescopic slide bars 49, and the bottom ends of the guide shafts 410 are slidably engaged in the corresponding V-shaped guide grooves 48. A push-pull rod 46 is fixedly mounted on the outer side end of the slider 47. An outer end plate 44 is fixedly mounted on the end of the push-pull rod 46. A pressure spring 45 is fixedly mounted on the inner side surface of the outer end plate 44. One end of the pressure spring 45 is abutted against one side of the clamp seat 42. The limit stopper 43 is fixedly mounted on one side of the bracket 22 and can abut against the outer end plate 44 for limiting position.

[0053] Specifically, when the foldable support frame is in the folded state, the outer end plate 44 abuts against one side of the limit stop block 43 to abut and fix the slider 47 against the inside of the clamp seat 42. At this time, the guide shaft 410 is located at the tip of the V-shaped guide groove 48, and the telescopic slide bars 49 on both sides drive the clamp block 41 to be in a closed clamping state, so that the clamp block 41 clamps and fixes the threaded sleeve 33, and then locks and fixes the lower support rod 32 relative to the upper support rod 31 to prevent the lower support rod 32 from shaking and colliding when the corn harvester moves. When the upper support rod 31 rotates and moves in the vertical direction, the upper support rod 31 drives the clamp seat 42 and the outer end plate 44 to move. 4 moves in the direction away from the bracket 22, so that the outer end plate 44 is separated from the limit stop block 43. At this time, the outer end plate 44 moves in the direction away from the clamp seat 42 under the elastic force of the pressure spring 45, and pulls the slider 47 to the outside of the clamp seat 42 through the push-pull rod 46. When the slider 47 slides outward, it drives the corresponding guide shaft 410 to move in the opposite direction and open through the V-shaped guide groove 48. At the same time, the guide shaft 410 drives the clamp block 41 to move in the opposite direction and open through the telescopic slide bar 49, so that the clamp block 41 releases the clamping of the threaded sleeve 33, thereby releasing the lock of the lower support rod 32, which is convenient for the subsequent rotation and expansion of the lower support rod 32.

[0054] When the upper support rod 31 is rotated, folded and reset, the upper support rod 31 drives the clamp seat 42 and the outer end plate 44 to move in the direction close to the bracket 22, so that the outer end plate 44 abuts against one side of the limit stop block 43. Then, as the upper support rod 31 and the clamp seat 42 continue to move and reset, the slider 47 slides toward the inside of the clamp seat 42 and resets under the abutment of the push-pull rod 46, the outer end plate 44 and the limit stop block 43. At this time, the slider 47 drives the corresponding guide shaft 410 to move toward each other through the V-shaped guide groove 48, and at the same time, the guide shaft 410 drives the clamp block 41 to move toward each other through the telescopic slide bar 49, so that the clamp block 41 clamps the threaded sleeve 33, thereby restoring the locking of the lower support rod 32.
