Description

Technical Field

[0001] The utility model belongs to the technical field of grain drying auxiliary tools, and in particular relates to a universal lifting structure for an agricultural frame. Background Art

[0002] During the grain harvesting process, a lot of drying aids are often used. In order to improve the collection efficiency, a push plate is generally installed in front of the vehicle, and the push plate is used to push the grain to the middle of the drying space. The utility model patent CN217929521U declared by the applicant in 2022 discloses a grain drying pushing device. By setting a pulling mechanism, when it is necessary to push the grain, the pulling mechanism is controlled to make the bottom of the push plate flush with the ground, and then the engine is turned on, the vehicle drives the push plate to move and push the grain together. When it is necessary to reverse, the pulling mechanism is controlled to raise the push plate to make the push plate leave the grain to avoid pulling the grain back. The height of the push plate is adjusted by the pulling mechanism to avoid friction loss caused by the push plate contacting the ground when not working.

[0003] However, in actual use, due to the lack of a lifting structure, the push plate can only be slightly lifted by a pulling mechanism to avoid friction with the ground, but the push plate cannot be fully lifted. This will result in the device being not universal for drying operations at different heights, making it inflexible and inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the push plate cannot be fully raised and the device is not flexible.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a universal lifting structure for an agricultural frame, comprising a U-shaped rod, a connecting piece and a lifting mechanism, wherein the right side of the U-shaped rod is fixedly installed with a connecting piece, and the left side of the U-shaped rod is fixedly installed with a lifting mechanism, and the lifting mechanism comprises an L-shaped rod, a connecting swivel and a connecting rod, two of the L-shaped rods are fixedly installed on the left side of the U-shaped rod, the connecting swivel is fixedly installed on the left side of the L-shaped rod, the connecting rod is fixedly installed on the left side of the connecting swivel, the connecting rod is connected to the top end of a drying baffle, one of the ends of the L-shaped rods is fixedly connected with a control rod, the left side of the control rod is fixedly connected with a handle, and the right side of the connecting piece is fixedly connected to the handle of a drying aid.

[0006] As a preferred embodiment of the utility model, the connecting member includes a connecting ring, a mounting groove, an arc plate, a first mounting hole, a first threaded rod and a first nut, the connecting ring is fixedly installed on the right side of the U-shaped rod, and the mounting groove is opened on the right side of the connecting ring.

[0007] As a preferred embodiment of the present invention, the arc plate is movably mounted on the top of the mounting groove, and the first mounting holes are respectively opened on the right side of the connecting ring and the top of the arc plate.

[0008] As a preferred embodiment of the present invention, the first threaded rod is fixedly mounted in the inner cavity of the first mounting hole, and the two first nuts are respectively fixedly mounted on the top and bottom of the first threaded rod.

[0009] As a preferred embodiment of the utility model, the connecting ends of the U-shaped rod and the L-shaped rod are both provided with second mounting holes, the inner cavity of the second mounting hole is fixedly mounted with a second threaded rod, and the front and back sides of the second threaded rod are both fixedly mounted with second nuts.

[0010] As a preferred embodiment of the utility model, a connecting thread is provided at the left end of the L-shaped rod, a fourth nut is fixedly installed outside the connecting thread, a first connecting tube is provided on the right side of the connecting swivel, and a second connecting tube is provided on the left side of the connecting swivel.
