Description

Technical Field

[0001] This invention relates to the field of grain unloading technology for grain transport vehicles, and in particular to an auxiliary device for unloading grain. Background Technology

[0002] When unloading grain, grain trucks typically move onto an unloading device. Through the unloading device and the truck's own tilting, the grain is unloaded from the rear compartment. A Chinese utility model patent, CN216511620U, for a grain truck unloading platform, uses a support drive assembly to drive a fixed plate closer to a limiting seat, thus restricting the movement of the truck's tires and preventing the truck from tilting during unloading. The fixed plate is also secured with a fixing strap, and finally, a lifting drive mechanism controls the body to rotate around a first fixed seat, causing the truck to tilt towards the limiting seat, thus smoothly completing the unloading of the grain.

[0003] In practical use, the aforementioned grain unloading auxiliary device relies solely on a limiting seat and a fixing belt to restrain the grain transport vehicle. Since the limiting seat is merely an open, baffle-like structure, and the fixing belt only restricts the front end of the vehicle, it fails to adequately restrict the axial movement of the tires (especially the rear wheels). This causes the grain transport vehicle to sway slightly as the unloading device tilts, ultimately reducing the overall restraint effect. Furthermore, the relatively fixed positions of the limiting seat and fixing belt prevent the limiting seat from precisely restraining grain transport vehicles with varying wheelbases when the unloading device requires fixing. Summary of the Invention

[0004] In view of this, it is necessary to provide a grain unloading auxiliary device to solve the technical problem that the existing technology cannot achieve accurate and good positioning of grain transport vehicles with different wheel gauges.

[0005] This invention provides a grain unloading auxiliary device, including a hydraulic tipping drive mechanism, an unloading platform, and a limiting component;

[0006] The top of the unloading platform has a loading port and an unloading port at both ends, and several positioning slots are provided on one side of both the loading port and the unloading port.

[0007] The limiting component includes at least two limiting wheel blocks with openings on one side and several adjusting plates. The two limiting wheel blocks are located on both sides along the axis of the unloading platform and are detachably connected to the positioning groove. The adjusting plates are inserted into the limiting wheel blocks to adjust the opening width of the limiting wheel blocks, and the opening of the limiting wheel blocks points to the side of the loading port.

[0008] The hydraulic tipping drive mechanism is located in the middle of the unloading platform and is used to drive one end of the loading port to rotate upward.

[0009] In one embodiment of the present invention, the positioning grooves are arranged in two groups, each group being located on the opposite side of the loading port and the unloading port, and each group having at least four grooves evenly distributed.

[0010] In one embodiment of the present invention, the positioning groove is configured as a regular hexagonal groove, which is used to engage with the bottom end of the wheel limiting block.

[0011] In one embodiment of the present invention, the opening of the regular hexagonal groove is provided with a guide angle.

[0012] In one embodiment of the present invention, the wheel limiting block includes a locking post and a limiting portion located at the top of the locking post. The locking post is adapted to the positioning groove, and the opening of the wheel limiting block is located on one side of the locking post.

[0013] In one embodiment of the present invention, the inner wall of the opening of the wheel limiting block is symmetrically provided with limiting grooves, which are used to be detachably connected to the adjusting plate.

[0014] In one embodiment of the present invention, at least three limiting grooves are provided on one side.

[0015] In one embodiment of the present invention, protective railings are provided on both sides of the top of the unloading platform.

[0016] In one embodiment of the present invention, the guardrail is provided with a weight-reducing groove.

[0017] In one embodiment of the present invention, a guide platform is provided on one side of the feeding port.

[0018] Compared with the prior art, the grain unloading auxiliary device provided by the present invention has the following beneficial effects:

[0019] In this invention, wheel limiting blocks are distributed on both sides along the axis of the unloading platform and detachably connected to positioning slots. Adjustable distance plates are inserted into the wheel limiting blocks to adjust the opening width of the wheel limiting blocks, with the openings of the wheel limiting blocks pointing towards the loading port. This allows the grain transport vehicle to reverse through the loading port and approach the unloading port, and the tires of the grain transport vehicle enter through the openings of the wheel limiting blocks, ultimately being limited by the wheel limiting blocks, significantly improving the axial limitation effect on the tires. In particular, several positioning slots are provided on both the unloading port and the loading port side, allowing the four tires of the grain transport vehicle to be limited by inserting the wheel limiting blocks into different positioning slots, effectively limiting grain transport vehicles with different wheelbases while significantly improving the limiting capability. The design of the adjustable distance plates can further limit the specifications and dimensions of different tires, effectively improving the precise limiting effect.

[0032] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0033] Please see Figures 1-8 This invention provides a grain unloading auxiliary device, including a hydraulic tipping drive mechanism 100, an unloading platform 200, and a limiting component 300. The top two ends of the unloading platform 200 have a feeding port 210 and a discharging port 220, respectively. Each of the feeding port 210 and the discharging port 220 has a plurality of positioning grooves 230 on one side. The limiting component 300 includes at least two limiting wheel blocks 310 with openings on one side and a plurality of adjusting plates 320. The two limiting wheel blocks 310 are respectively located on both sides along the axis of the unloading platform 200 and are detachably connected to the positioning grooves 230. The adjusting plates 320 are inserted into the limiting wheel blocks 310 to adjust the width of the opening 311 (i.e., the opening mentioned above) of the limiting wheel blocks 310, and the opening 311 of the limiting wheel blocks 310 points to the feeding port 210. The hydraulic tipping drive mechanism 100 is located in the middle of the unloading platform 200 and is used to drive one end of the feeding port 210 to rotate upward.

[0034] In use, the grain truck is first reversed through the loading port 210, so that the rear wheels of the grain truck and the wheel limiting block 310 enter the opening 311 of the wheel limiting block 310. This effectively limits the rear wheels of the grain truck by the opening 311 of the wheel limiting block 310, thereby effectively limiting the axial direction of the rear wheels of the grain truck. Furthermore, since several positioning slots 230 are provided on one side of both the loading port 210 and the unloading port 220, the operator can adjust the wheel limiting block 310 according to the specifications and dimensions of different grain trucks and place it into different positioning slots 230, effectively meeting the limiting requirements of grain trucks with different wheel gauges. In addition, since the adjusting plate 320 is inserted into the wheel limiting block 310 to adjust the width of the opening 311 of the wheel limiting block 310, this can further allow for precise adjustment and limiting of tires of different specifications and sizes. Preferably, the thickness of the adjusting plate 320 can be designed in combination or multiple sets according to common tire width differences, so as to better meet the limiting requirements of grain transport vehicles.

[0035] To prevent the grain truck from reversing too quickly, a slot 240 is provided on one side of the unloading port 220. A buffer strip 600 is inserted into the slot 240 to slow down and warn the grain truck.

[0036] In order to better adjust the positional relationship of the wheel limiting blocks 310, in one embodiment of the present invention, the positioning grooves 230 are arranged in two groups, each group is respectively located on the opposite side of the loading port 210 and the unloading port 220, and each group has at least four grooves evenly arranged.

[0037] Furthermore, in one embodiment of the present invention, the positioning groove 230 is configured as a regular hexagonal groove 231, which is used to engage with the bottom end of the limiting wheel block 310. Specifically, the regular hexagonal structural design can make the limiting more secure.

[0038] Furthermore, in one embodiment of the present invention, the opening of the regular hexagonal groove 231 is provided with a guide angle 232, which can effectively improve the smoothness of the assembly and disassembly of the wheel limit block 310.

[0039] Furthermore, in one embodiment of the present invention, the wheel limiting block 310 includes a locking post 312 and a limiting part 313 located at the top of the locking post 312. The locking post 312 is adapted to fit the positioning groove 230, and the opening 311 of the wheel limiting block 310 is located on one side of the locking post 312. This allows the grain transport vehicle to engage with the opening 311 of the wheel limiting block 310 immediately after reversing.

[0040] To facilitate the replacement of the adjusting plate 320, in one embodiment of the present invention, symmetrical limiting grooves 314 are formed on the inner wall of the opening 311 of the limiting wheel block 310. The limiting grooves 314 are used to detachably connect with the adjusting plate 320. Specifically, a pin 321 can be fixedly connected to one side of the adjusting plate 320 to extend into the limiting groove 314 to form a snap-fit ​​relationship and prevent it from falling off easily.

[0041] Furthermore, in one embodiment of the present invention, at least three single-sided limiting grooves 314 are provided, which can enhance the stability of the connection between the adjusting piece 320 and the limiting groove 314.

[0042] To enhance the protection of the unloading platform 200, in one embodiment of the present invention, protective railings 400 are provided on opposite sides of the top of the unloading platform 200.

[0043] In order to effectively reduce the weight of the guardrail 400, in one embodiment of the present invention, the guardrail 400 is provided with a weight-reducing groove 410.

[0044] In order to allow the grain truck to enter the unloading platform 200 more smoothly, in one embodiment of the present invention, a guide platform 500 is provided on one side of the loading port 210.

[0045] In practical use, the aforementioned grain unloading auxiliary device first reverses the grain truck onto the unloading platform 200. Then, it reverses according to the different positions of the wheel limiting blocks 310, ensuring that both rear wheels of the grain truck enter the openings 311 of the corresponding wheel limiting blocks 310, forming a limiting effect through a snap-fit ​​mechanism. Since the openings 311 of the wheel limiting blocks 310 can effectively limit the axial direction of the tires on both sides, this effectively improves the overall limiting effect of the grain truck. In addition, after the grain truck is parked, the positioning groove 230 near the loading port 210 can achieve coarse positioning of the front wheels of the grain truck with a certain gap, thereby assisting in limiting the grain truck. Then, the hydraulic tipping drive mechanism 100 rotates the unloading platform 200, causing one end of the loading port 210 to rotate upwards, allowing the grain truck to unload grain more smoothly. It is worth mentioning that since several positioning slots 230 are provided on one side of both the loading port 210 and the unloading port 220, the operator can adjust the wheel limit block 310 according to the specifications and dimensions of different grain transport vehicles and place the wheel limit block 310 into different positioning slots 230, effectively meeting the limiting requirements of grain transport vehicles with different wheel gauges. The adjusting plate 320 is inserted into the wheel limit block 310, which can further target tires of different specifications and sizes, and make precise adjustments and limits on the tires by using the adjusting plate 320.

[0046] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
