Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a quick disassembly and assembly secondary debris removal device. Background Art

[0002] Corn harvesters have height restrictions during transportation and cannot exceed a certain height. Due to the structural layout of some corn harvesters, the secondary debris removal device is at the highest point of the vehicle and will be super high during transportation. Therefore, the secondary debris removal device needs to be removed during transportation to meet the transportation requirements of the corn harvester. Generally, the secondary debris removal device of a corn harvester is disassembled and lifted by multiple people, which is time-consuming, labor-intensive and has a high risk factor. In addition, the fixing bolts need to be removed one by one during disassembly and assembly, which makes the disassembly operation troublesome.

[0003] Patent CN211671412U discloses a grass discharge device for a corn harvester, including an elevator, a fan, a stem discharge roller device, a secondary chopping device and a grass discharge port, wherein the fan is arranged below the elevator, the stem discharge roller device is arranged at the outlet side of the elevator, the secondary chopping device is arranged at the side of the stem discharge roller device away from the elevator, and the grass discharge port is arranged at the side of the secondary chopping device away from the stem discharge roller device. The height of the corn harvester equipped with the grass discharge device will be too high during transportation, and the grass discharge device needs to be disassembled first, and then the corn harvester is transported to the destination, and then the grass discharge device is installed on the corn harvester, which is troublesome to operate. Therefore, it is necessary to develop a mechanism that can quickly disassemble and assemble the secondary debris discharge device to facilitate the transportation of the corn harvester.

[0006] Furthermore, one end of the connecting rod is connected to the secondary debris removal device, and the other end is connected to the connecting plate through a pin shaft. The pin shaft is arranged in the middle of the connecting plate. The connecting rod drives the secondary debris removal device to rotate around the pin shaft. The outer edge shape of the connecting plate is adapted to the trajectory of the secondary debris removal device rotating around the pin shaft.

[0007] Furthermore, the ear elevator and the secondary debris removal device are fixed by a quick locking mechanism and fixing bolts, the fixing bolts are installed on the side walls of the secondary debris removal device, and the quick locking mechanism is installed on the upper wall of the secondary debris removal device.

[0008] Furthermore, the secondary debris removal device and the side wall of the grass outlet are fixed by hinges and latches, and the secondary debris removal device and the upper wall of the grass outlet are fixed by a quick locking mechanism.

[0009] Furthermore, the quick locking mechanism is a snap-on quick clamp.

[0010] Furthermore, there are 3 hinges and 2 latches, and the hinges and latches are arranged at intervals.

[0011] When the utility model discloses a quick disassembly and assembly secondary debris removal device, when working, first the latch is pulled out, and the quick locking mechanism between the secondary debris removal device and the grass outlet is opened. The grass outlet and the secondary debris removal device are disengaged by rotating the hinge, so that the grass outlet and the secondary debris removal device are separated. Then the fixing bolts of the secondary debris removal device and the ear elevator are removed, and the quick locking mechanism between the secondary debris removal device and the ear elevator is opened. The secondary debris removal device is rotated downward around the pin axis, and the secondary debris removal device is lowered, so that the overall height of the corn harvester is reduced, which is convenient for transportation.

[0012] By adopting the above technical solution, the utility model achieves the following beneficial effects: the utility model realizes the secondary debris removal device to be rotated and lowered from the upper end of the ear elevator through the cooperation of the connecting plate, the connecting rod and the pin shaft, thereby lowering the whole vehicle and the vehicle transportation height, and can be operated by one person, saving time and effort, and being safe to operate. In addition, the grass outlet can be quickly removed from the secondary debris removal device through hinges, latches and quick locking devices, solving the problem that the bolts on the outer side of the grass outlet are difficult to remove and the operation is troublesome. The overall structure is simple, the performance is reliable, and the burden of disassembly and assembly on the operator is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
