Description

Technical Field

[0001] This invention relates to agricultural machinery, and in particular to a circular cotton harvester and its lifting device. Background Technology

[0002] Currently, the circular cotton harvester used both domestically and internationally changes the transport height by separating the lower parts of the front and rear compartments of the baling device and placing them horizontally on the machine frame. This method is complex, costly, and heavy. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a circular cotton harvester and its lifting device, which addresses the above-mentioned deficiencies of the prior art.

[0004] To achieve the above objectives, the present invention provides a lifting device for a circular cotton harvester, comprising:

[0005] A lifting mechanism is installed on the steering axle of the circular cotton harvester and connected to the frame of the circular cotton harvester, used to enable the frame to swing around the front wheel axle of the circular cotton harvester;

[0006] A lifting guide mechanism is provided corresponding to the lifting mechanism to ensure that the steering axle does not deviate or tilt during the lifting process;

[0007] A locking mechanism for locking the steering axle in its raised or lowered position; and

[0008] A body lifting mechanism is located in front of the steering axle and connected to the frame, for raising or lowering the frame so that the steering tires of the steering axle are on the ground or off the ground.

[0009] The lifting device of the circular cotton harvester described above includes a hydraulic cylinder. The cylinder body of the hydraulic cylinder is mounted on the steering bridge of the steering axle. The piston rod of the hydraulic cylinder is connected to the frame. The extension and retraction of the piston rod causes the frame to swing around the front wheel axle of the circular cotton harvester, thereby reducing the ground clearance of the baling device of the circular cotton harvester.

[0010] The lifting device of the circular cotton harvester described above, wherein the locking mechanism includes a front connecting bar and a rear connecting frame, the front connecting bar being connected to the front part of the steering bridge and the frame, and the rear connecting frame being connected to the rear part of the steering bridge and the frame respectively.

[0011] In the lifting device of the circular cotton harvester described above, the front connecting strip and the rear connecting frame are detachably connected to the steering bridge.

[0012] In the aforementioned lifting device of the circular cotton harvester, the front connecting bar and the rear connecting frame are respectively connected to the steering bridge by bolts.

[0013] The lifting device of the circular cotton harvester described above, wherein the lifting guide mechanism includes a front guide block and a rear guide block, the front guide block being configured corresponding to the front connecting strip and the rear guide block being configured corresponding to the rear connecting frame, is used to prevent the steering axle from shifting or tilting during the lifting process.

[0014] In the lifting device of the circular cotton harvester described above, guide bars and stops are respectively provided on the front guide block and the rear guide block. The guide bars are used to limit the left and right deviation of the steering bridge; the stops are used to straighten the steering bridge forward and backward.

[0015] The lifting device of the circular cotton harvester described above includes a lifting cylinder, wherein the lifting mechanism comprises a lifting cylinder, the cylinder body of which is mounted on the frame, and a support seat is provided at the top of the piston rod of the lifting cylinder.

[0016] In the aforementioned circular cotton harvester's lifting device, the lifting mechanism, lifting guide mechanism, locking mechanism, and machine body lifting mechanism are all symmetrical structures with the longitudinal centerline of the steering axle as the center of symmetry.

[0017] To better achieve the above objectives, the present invention also provides a circular cotton harvester, which includes the aforementioned lifting device.

[0018] The technical effects of this invention are as follows:

[0019] The lifting device of the present invention can reduce the rear transport height of the circular cotton harvester. When the hopper is closed, the packing device swings up or down along with the frame around the front wheel axis. When it swings down, the height of the highest point of the machine body from the ground is reduced to meet the needs of road transport and field transfer. The method of lowering the transport height by laying the packing device horizontally is no longer required. The structure is simple and the manufacturing cost is reduced.

[0048] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0049] See Figure 1 , Figure 1This is a schematic diagram of a circular cotton harvester according to an embodiment of the present invention. The circular cotton harvester of the present invention includes a frame 1 and a chassis 2 mounted on the frame 1, a cotton harvesting head 3, a suspension device 4, a cotton conveying system 5, a cotton collection box 6, a cotton feeding device 10, a lifting device 7, a baling device 8, and an unbaling device 9. The composition, structure, relative positions, connections, and functions of the other components of the circular cotton harvester are all mature existing technologies, and therefore will not be described in detail here. Only the lifting device 7 of the present invention will be described in detail below.

[0050] See Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the lifting device 7 according to an embodiment of the present invention. Figure 3 for Figure 2 A top view. The lifting device 7 of the circular cotton harvester of the present invention is used to raise to the working state and lower to the road transport state, including: a lifting mechanism 71, installed on the steering axle 23 of the circular cotton harvester and connected to the frame 1 of the circular cotton harvester, for lifting the frame 1 to realize the frame 1 swinging around the front wheel axle 24 of the circular cotton harvester; a lifting guide mechanism 72, corresponding to the lifting mechanism 71, for ensuring that the steering axle 23 does not deviate or tilt during the lifting process; a locking mechanism 73, for locking the steering axle 23 in the raised or lowered position; and a machine body lifting mechanism 74, located in front of the steering axle 23 and connected to the frame 1, for lifting or lowering the frame 1 so that the steering tire 22 of the steering axle 23 touches or leaves the ground, facilitating the lifting and locking of the steering axle 23.

[0051] The lifting mechanism 71 includes a hydraulic cylinder. The cylinder body of the hydraulic cylinder is mounted on the steering bridge frame 21 of the steering axle. The piston rod of the hydraulic cylinder is connected to the frame 1. The extension and retraction of the piston rod causes the frame 1 to swing around the front wheel axle 24 of the circular cotton harvester, thereby reducing the ground clearance of the packing device 8 of the circular cotton harvester.

[0052] The locking mechanism 73 in this embodiment includes a front connecting bar 731 and a rear connecting frame 732. The front connecting bar 731 is located on the steering bridge 21 and is connected to the front of the steering bridge 21 and the frame 1. The rear connecting frame 732 is located at the rear of the steering bridge 21 and is connected to the rear of the steering bridge 21 and the frame 1, respectively. The front connecting bar 731 and the rear connecting frame 732 are detachably connected to the steering bridge 21. Preferably, the front connecting bar 731 and the rear connecting frame 732 are connected to the steering bridge 21 by bolts, locking the raised or lowered steering bridge 23 in place with bolts, thus integrating the steering bridge 23 with the frame 1 to prevent loosening, shaking, or deformation, meeting the requirements of field operations and road transportation.

[0053] The lifting guide mechanism 72 of this embodiment includes a front guide block 721 and a rear guide block 722. The front guide block 721 is disposed corresponding to the front connecting strip 731, and the rear guide block 722 is disposed corresponding to the rear connecting frame 732. These mechanisms limit the movement of the front connecting strip 731 and the rear connecting frame 732 connected to the steering bridge 21, preventing the steering bridge 23 from shifting or tilting during lifting. Both the upper and lower parts of the front guide block 721 and the rear guide block 722 have bolt holes for bolt connection. The front guide block 721 and the rear guide block 722 are respectively provided with guide strips and stops. The guide strips limit the lateral shift of the steering bridge 21; the stops are used to straighten the steering bridge 21 forward and backward.

[0054] In this embodiment, the lifting mechanism 74 includes a lifting cylinder, the cylinder body of which is mounted on the frame 1, and a support seat 741 is provided at the top of the piston rod of the lifting cylinder. Wherein, as... Figure 3 As shown, the lifting mechanism 71, lifting guide mechanism 72, locking mechanism 73 and body lifting mechanism 74 are all arranged in a symmetrical structure with the longitudinal centerline of the steering axle 23 as the center of symmetry.

[0055] During operation, the circular kiln cotton harvester transitions from transport mode to operating mode. The piston rod of the lifting cylinder of the machine body lifting mechanism 74 is controlled to raise the frame 1 to its highest position, lifting the steering tire 22 off the ground. The piston rod of the lifting cylinder of the lifting mechanism 71 is then controlled to extend to its highest position. The front connecting strip 731 is connected to the front guide block 721 with bolts, and the rear end of the rear connecting frame 732 is connected to the rear guide block 722. After locking, the piston rod of the lifting cylinder of the machine body lifting mechanism 74 is controlled to retract, causing the frame 1 to fall. The circular kiln cotton harvester enters the operating mode once the piston rod is fully retracted.

[0056] During transport, the circular kiln cotton harvester changes from operating mode to transport mode. The piston rod of the lifting cylinder of the machine body lifting mechanism 74 is controlled to raise the frame 1 to the highest position, and the steering tire 22 is off the ground. First, the connection between the rear connecting frame 732 and the rear guide block 722 at the rear of the frame 1 is removed. Then, the connecting bolts between the steering bridge 21 and the front guide block 721 are removed, and the lock is released. The piston rod of the lifting cylinder of the lifting mechanism 71 is controlled to retract to the position. First, the front connecting bar 731 is connected to the front guide block 721 located on the frame 1 with bolts. Then, the rear connecting frame 732 is connected to the rear guide block 722. After locking is completed, the piston rod of the lifting cylinder of the machine body lifting mechanism 74 is controlled to retract, so that the frame 1 falls until the piston rod of the lifting cylinder is fully retracted and the steering tire 22 touches the ground. The circular kiln cotton harvester enters the road transport transfer mode.

[0057] The circular cotton harvester of this invention features a lifting mechanism 71 that, through the extension and retraction of a hydraulic cylinder piston rod, causes the frame 1 to swing around its front axle, thereby lowering the ground clearance of the baling device 8 located at the rear of the frame 1 and improving road passability. A lifting guide mechanism 72 ensures that the steering axle does not shift or tilt during lifting. A locking mechanism 73 locks the raised or lowered steering axle, ensuring it is integrated with the frame 1 and preventing loosening, shaking, or deformation. The frame 1 lifting mechanism raises or lowers the frame 1, lifting the steering axle tires off the ground, facilitating the raising, lowering, and locking of the steering axle. This eliminates the need for the front and rear compartments of the baling device 8 to be placed horizontally on the frame 1 when transport height is excessive, resulting in a simple structure, low cost, and easy operation.

[0058] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
