[0002] A grain storage cage (or simply a cage) is a component used in grain storage to promote ventilation at the bottom of grain piles. It is arched with perforated mesh on the surface. Because it needs to have good load-bearing capacity, the cage is made of metal and has a certain weight. Traditionally, moving a cage usually requires multiple people working together, bending over and lifting it by hand, which is very strenuous and can easily cause back injuries. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a grain storage cage transport vehicle that, by setting up cantilever beams and arc-shaped plates, allows for the transport of the cages using a vehicle, thus saving manpower.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a grain warehouse ground cage transport vehicle, comprising: The frame has two symmetrical movable wheels rotatably mounted on its bottom, and the frame is equipped with handrails; A cantilever beam, one end of which is hinged to the vehicle frame, and the other end of which is fixed with an arc-shaped plate; When the arc-shaped plate is inserted under the ground cage, the handrail is pressed down, and the cantilever beam rotates around the moving wheel and lifts the ground cage.

[0005] Preferably, it further includes an adjustment device disposed on the frame for adjusting the angle between the cantilever beam and the frame; the adjustment device includes an adjustment rod hinged to the frame, the cantilever beam having an oblong hole for the adjustment rod to pass through, and the adjustment rod having a limiting component for limiting the position of the cantilever beam on the adjustment rod.

[0006] Preferably, the limiting component includes two gaskets, which are respectively fitted onto the adjusting rods on the upper and lower sides of the cantilever beam. The adjusting rods are threaded, and a nut is threaded onto the adjusting rod on the side of the gasket away from the cantilever beam.

[0007] Preferably, the cantilever beam includes a first rod and a second rod, the first rod and the second rod are hinged together, the axis of the hinge axis between the first rod and the second rod is in the plane containing the upper surfaces of the first rod and the second rod, and when the first rod and the second rod are at a 180-degree angle, the adjacent ends of the first rod and the second rod abut against each other.

[0008] Preferably, the arc-shaped plate is fixed to the end of the first rod away from the second rod, and the waist-shaped hole is opened on the second rod.

[0009] Preferably, the lower surfaces of the first rod and the second rod are both fixed with limit seats, and the two limit seats are respectively connected to the two ends of a tension spring.

[0010] Preferably, the first rod is provided with a limiting mechanism for limiting the angle between the first rod and the second rod.

[0011] Preferably, the limiting mechanism includes a pull rod fixed to the lower surface of the first rod body, the end of the pull rod extending to the lower part of the second rod body, and protrusions fixed on both sides of the end of the pull rod.

Users can use the lever principle, with the moving wheel as the fulcrum, to press down on the handrail, causing the arc-shaped plate to lift up. When the arc-shaped plate and part of the cantilever beam are inserted under the ground cage, pressing down on the handrail will cause the arc-shaped plate to lift the ground cage. Then, by pushing the handrail, the ground cage can be moved using this transport vehicle, eliminating the need for manual handling and greatly reducing the labor intensity of manual labor. This utility model features an adjustment device on the frame. By rotating the nuts, the position of the two nuts on the adjustment rod can be adjusted, thereby adjusting the angle of the cantilever beam on the frame.

[0024] 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.

[0025] Example 1 like Figures 1 to 4As shown, Embodiment 1 of this utility model provides a grain storage cage transport vehicle for convenient handling of grain storage cages. It includes a frame 1, which is welded from cylindrical steel pipes and possesses sufficient structural strength and load-bearing stability. Two rotatable wheels 2 are symmetrically arranged at the bottom front end of the frame 1. The axles of the wheels 2 are equipped with bearings, facilitating smooth movement on the grain storage floor. A handrail 3 extends upwards from the rear end of the frame 1 and is fixedly installed. The surface of the handrail 3 can be further covered with a non-slip rubber layer for easy gripping and application of force by the operator.

[0026] like Figure 1 As shown, a cantilever beam 4 is hinged to the middle of the frame 1 via a pin welded to the frame 1. The cantilever beam 4 is a long, straight rod structure made of high-strength rectangular steel tubing. At the front end of the cantilever beam 4, i.e., the end furthest from the frame 1, an arc-shaped plate 5 is fixedly connected. The arc-shaped plate 5 is formed by bending steel plate, with its arc-shaped opening facing upwards, facilitating insertion into the lower side of the ground cage. The curvature of the arc-shaped plate 5 matches the inner curvature of the ground cage, serving as a limiting force to prevent the ground cage from swaying on the cantilever beam 4.

[0027] On the frame 1, two limiting baffles 11 are welded on both sides of the cantilever beam 4. The beam body is restricted between the two baffles to prevent the cantilever beam 4 from swaying left and right during transportation and to improve the running stability.

[0028] When moving the ground cage, the operator first grips the handle 3 and pushes the transport vehicle near the target ground cage, inserting the curved plate 5 at the front end of the cantilever beam 4 into the gap at the bottom of the ground cage. Then, the operator presses down on the handle 3, causing the entire frame 1 to rotate around the rear moving wheel 2. The cantilever beam 4 rotates around the central axis of the moving wheel 2, lifting the front curved plate 5 upwards and prying the ground cage off the ground. Once the ground cage is stably raised to a certain height, the operator can push the transport vehicle using the handle 3 to easily move the ground cage to the target location. The entire operation utilizes the lever principle, saving effort and increasing efficiency, avoiding the high labor intensity and low efficiency associated with manual handling.

[0029] Example 2 Based on Embodiment 1, Embodiment 2 adds an adjustment device to enable the transport vehicle to adapt to operators of different heights, thereby improving human-machine efficiency.

[0030] The transport vehicle in this second embodiment also includes a frame 1, wheels 2, handrails 3, cantilever beams 4, and curved plates 5, and its basic structure and connection relationship are the same as in the first embodiment. The difference is that an adjustment device is added to the front end of the frame 1.

[0031] The adjusting device includes an adjusting rod 6. One end of the adjusting rod 6 is hinged to the frame 1 via a pin, with the hinge point located in front of the hinge point between the cantilever beam 4 and the frame 1. A slotted hole 7 is provided in the middle of the cantilever beam 4, through which the free end of the adjusting rod 6 passes. External threads are machined on the body of the adjusting rod 6. Two washers 8 are respectively fitted onto the adjusting rod 6 on the upper and lower sides of the cantilever beam 4, i.e., tightly against the upper and lower surfaces of the cantilever beam 4. Two nuts 9 are threaded onto the adjusting rod 6 and located outside the two washers 8.

[0032] By tightening the two nuts 9, the positions of the two washers 8 on the adjusting rod 6 can be changed, thereby changing their limiting position on the cantilever beam 4. The slotted hole 7 on the cantilever beam 4 can slide along the body of the adjusting rod 6, so that the cantilever beam 4 has a certain swing range.

[0033] The adjustment device allows the equipment to be personalized according to the user's height and personal habits, making it easier to insert the cantilever beam 4 into the underside of the ground cage, significantly improving the comfort and convenience of use.

[0034] Example 3 like Figures 5 to 7 As shown, based on Embodiment 1 and Embodiment 2, Embodiment 3 optimizes the design of the cantilever beam 4 structure.

[0035] In this embodiment, the cantilever beam 4 is divided into two parts: a first rod 41 and a second rod 42. The front end of the first rod 41 is fixedly connected to an arc-shaped plate 5, and its rear end is connected to the front end of the second rod 42 via a hinge shaft 43. Figure 7 As shown, the axis of the hinge shaft 43 is located on the upper surfaces of the first rod 41 and the second rod 42. When the first rod 41 and the second rod 42 are fully extended and aligned, their ends abut against each other, forming a stable linear load-bearing structure. A waist-shaped hole 7 is formed on the second rod 42. The tail end of the second rod 42 is hinged to the frame 1.

[0036] A limiting seat 44 is fixed to the lower surface of the first rod 41 and the second rod 42, respectively. A tension spring 45 is connected between the two limiting seats 44. In the natural state, the tension of the tension spring 45 makes the first rod 41 and the second rod 42 form a straight line.

[0037] To limit the position of the cantilever beam 4 in its deployed state, this embodiment also includes a limiting mechanism, comprising a pull rod 46 fixed to the lower surface of the first rod 41, extending towards the second rod 42. The pull rod 46 has outwardly protruding portions 47 on both sides of its end. On the lower surface of the second rod 42, two parallel limiting plates 48 are fixed, located on either side of the end of the pull rod 46 and on the side of the protruding portions 47 closest to the first rod 41.

[0038] like Figure 7 As shown, when the second rod 42 is folded upward to a certain angle, the protrusion 47 at the end of the pull rod 46 just blocks the limiting plate 48, thereby preventing the second rod 42 from continuing to fold upward, thus limiting the range of the unfolding angle between the first rod 41 and the second rod 42.

[0039] In addition, a small roller 10 is rotatably mounted on the lower side of the front end of the first rod 41. The roller 10 is made of nylon material, and its lowest point is slightly lower than the lowest point of the curved plate 5. When the front end of the cantilever beam 4 is extended into the bottom of the ground cage, the roller 10 contacts the ground first and rolls, greatly reducing the pushing resistance. Users do not need to worry about the curved plate 5 scraping the ground, making the operation more convenient and effortless.

[0040] like Figure 6 As shown, the user can lift the handrail 3 so that the first rod 41 and the second rod 42 are extended to the extent that the limiting plate 48 abuts against the protrusion 47. At this time, the first rod 41 is close to the ground, and the roller 10 provides front-end support, making it easier to insert the arc plate 5 into the bottom of the cage.

[0041] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
