Technical Field
[0001] This invention relates to the field of agricultural machinery technology, and more specifically to a folding locking device. Background Technology
[0002] Agricultural mechanization is the foundation of modern agriculture. With the development of agricultural mechanization, in order to make agricultural machinery and equipment convenient to use, improve safety, and adapt to various complex terrain conditions, many types of agricultural machinery and equipment need to be equipped with folding and locking devices.
[0003] Currently, the application of folding locking devices in agricultural machinery and equipment is relatively rare in the market. In response to the problems of agricultural machinery and equipment encountering bumpy and uneven roads during transportation, uneven ground and difficulty in turning during operation, as well as operator safety issues, a folding locking device has been designed to solve the above-mentioned shortcomings. Summary of the Invention
[0004] To address the safety issues caused by complex road surfaces during the transportation of existing agricultural machinery, this invention provides a folding locking device.
[0005] The technical solution adopted is as follows:
[0006] A folding locking device includes a main beam, a hydraulic cylinder assembly, a vertical beam welded joint, a main frame, and a folding support arm. One end of the main frame is hinged to a gearbox, and the other end is hinged to one end of the vertical beam welded joint. One end of the main beam is hinged to the gearbox. The other end of the vertical beam welded joint is hinged to one end of the hydraulic cylinder assembly, and the other end of the hydraulic cylinder assembly is hinged to the main beam. The main frame is provided with a frame slide groove. The folding support arm includes a limiting connecting rod and a limiting top rod. The top rod is horizontally fixed to one end of the limiting connecting rod, and the other end of the limiting connecting rod is hinged to the main beam. A guide plate is also provided on the limiting connecting rod near the limiting top rod. One end of the guide plate is hinged to the limiting connecting rod, and the other end is provided with a long slide groove. The hydraulic cylinder assembly is provided with a slider, which is fitted into the long slide groove. When the hydraulic assembly is driven, the slider moves along the long slide groove, so that the limiting top rod is engaged at one end or the other end of the frame slide groove.
[0007] When the hydraulic assembly is controlled to perform folding, the slider moves upward along the long slide groove, and the limiting rod is engaged with the end of the frame slide groove away from the main beam; when the hydraulic assembly is controlled to perform reverse action, the slider moves downward along the long slide groove, and the limiting rod is engaged with the end of the frame slide groove near the main beam.
[0008] Furthermore, the hydraulic assembly includes a push rod and a hydraulic cylinder. A U-shaped lug is fixed on the push rod, and a hydraulic cylinder lug is hinged to the U-shaped lug. A U-shaped plate is also fixed on the hydraulic cylinder lug. The slider is L-shaped and fixed to the U-shaped plate. The hydraulic cylinder is hinged to the vertical beam welded joint, and the push rod is hinged to the main beam.
[0009] Furthermore, the push rod is also provided with a baffle, and the U-shaped lug is fixed to the push rod between the baffle and the main beam.
[0010] Furthermore, the vertical beam welded component includes a vertical beam and a base plate, the base plate being fixed to one end of the vertical beam, and the other end of the vertical beam being hinged to the hydraulic cylinder.
[0011] The main frame includes a main frame crossbeam, a frame slide groove, and a straight connecting plate. The frame slide groove is fixed to the main frame crossbeam. The two ends of the straight connecting plate are respectively hinged to the gearbox and the main frame crossbeam. The main frame crossbeam is hinged to the base plate.
[0012] More preferably, the main frame crossbeam of the main frame is parallel to the horizontal plane.
[0013] Furthermore, the main beam includes a main crossbeam, a main inclined beam, and a gearbox connecting plate. The main crossbeam and the gearbox connecting plate are fixed to both ends of the main inclined beam. A rotating shaft is also provided in the middle of the main inclined beam, offset from the gearbox connecting plate. The push rod is rotatably connected to the rotating shaft through a push rod connecting plate provided at its end. Limiting connecting plates are also fixed on both sides of the main inclined beam. The limiting connecting plates are rotatably connected to the rotating sleeves fixed to the ends of the limiting connecting rods.
[0014] The technical solution of the present invention has the following advantages:
[0015] A. The device of the present invention uses hydraulic drive to fold and lock the mechanical equipment. At the same time, the limiting rod of the folding support arm is locked on one side of the slide groove of the main frame, thereby playing a role in locking and securing the mechanical equipment and preventing the mechanical equipment from shaking or not locking properly during transportation.
[0016] B. The device of the present invention can effectively improve the working efficiency of mechanical equipment and reduce the risk of safety accidents to operators. Attached Figure Description

The main frame crossbeam 401 of the main frame 4 should be parallel to the horizontal plane; the frame slide 402 is fixed to the main frame crossbeam 401, that is, welded to it. Figure 1 On the upper left side of the main frame crossbeam 401, the two ends of the straight connecting plate 403 are hinged to the gearbox 7 and the main frame crossbeam 401 respectively, and the main frame crossbeam 401 and the base plate 302 form a concentric hinge.
[0042] like Figure 2 As shown, the main beam 1 includes a main crossbeam 101, a main inclined beam 102, a limiting connecting plate 103, and a gearbox connecting plate 104.
