[0002] The existing harvester headers are used to harvest wheat and rice instead of grain harvester headers. They cannot harvest fallen crops, resulting in serious grain loss. The straw is directly placed on the ground, and farmers have to burn it before farming, which not only wastes the straw, but also causes environmental pollution and the harvest stubble is also very high. It takes a lot of manpower and material resources for farmers to collect it again. Summary of the invention

[0003] The utility model aims to solve the above-mentioned existing problems and provide a grain harvester ear and stem separation and collection device which can harvest fallen crops, reduce grain loss, and have low crop stubble after harvesting, so that farmers can cultivate crops well in the next year.

[0005] The lodging front foot is installed on the bottom of the steel plate at the front section of the bottom header chamber by bolts and jackets to lift the crop straw. The straw-supporting arm mechanism is installed on the rear side of the scissor mechanism and the top of the steel plate at the front section of the bottom header chamber by bolts and jackets to clamp the root of the crop straw. The knife frame connecting plate of the scissor mechanism is connected to the top of the steel plate at the front section of the bottom header chamber by bolts to cut off the root of the crop straw clamped by the straw-supporting arm. The first outer plate is welded to the pipe above the bottom header chamber, and the lower transmission mechanism is welded to the first outer plate to transmit the straw cut by the scissor mechanism and then send it to the reel chamber. The first bilateral symmetrical partitions are welded on the inner side of the first outer plate and on the bottom header chamber to separate the reel chamber separately so that the reel can cut the straw of the desired length.

[0006] The upper transmission mechanism is welded on the second outer plate to transmit the ears of seeds cut by the wheel scissors mechanism and then send them to the cutter room. The wheel scissors mechanism is installed on the bottom plate of the upper transmission mechanism through bolts and bearings, and is driven by the spur gear on the front driven shaft of the middle reed chain mechanism. The spur gear under the wheel scissors mechanism is used to realize the rotation of the wheel scissors mechanism, thereby cutting the ears of seeds. The middle reed chain mechanism is installed on the steel plate under the upper transmission mechanism through bolts, and the steel plate is connected to the top of the screw lifting mechanism. The bottom of the screw lifting mechanism is connected to the steel plate in the bottom cutting platform room through bolts and a jacket. In this way, under the transmission of the motor, the upper transmission mechanism, the second outer plate, the wheel scissors mechanism, and the middle reed chain mechanism of the upper mechanism will adjust the height of the cut ears with the screw lifting mechanism. The second bilateral symmetrical partitions are welded on the second outer plate and the bottom plate of the upper transmission mechanism, so as to prevent the ears of seeds from falling to other places during the transmission process and can be better sent to the cutter room.

[0007] The second outer plate is welded to the outer wall of the slide, and the inner wall of the slide is welded to the first outer plate and the pipe above the bottom header chamber, which not only fixes the outer plate but also forms an up and down sliding effect.

[0008] The power of the upper main drive sprocket and the lower main drive sprocket comes from the engine, so as to transmit the load required by the upper and lower layers and realize the role and function of each layer.

[0009] The utility model has the advantages that the device can harvest lodged crops, reduce grain loss, and the crop stubble is low after harvesting, which is convenient for farmers to cultivate well in the next year, saves a lot of manpower and material resources, and has high use value.

The Fuhe first spur gear (16-16) on the Fuhe active connecting shaft (16-11) drives the Fuhe second spur gear (16-17), the Fuhe third spur gear (16-18), the Fuhe fourth spur gear (16-19), and the Fuhe fifth spur gear (16-20) to mesh and transmit, so that the Fuhe first driven connecting shaft (16-11) is driven by the Fuhe first driven connecting shaft (16-11). The shaft (16-2) and the second driven connecting shaft (16-9) drive the first sprocket (16-1), the second sprocket (16-7), the third sprocket (16-8), the first chain (16-4), the second chain (16-14) and the chain (16-12) to form two chains for simultaneous transmission, and the tightness of the chains is adjusted by the first tensioning sprocket (16-3), the second tensioning sprocket (16-6) and the third tensioning sprocket (16-13).

[0035] The principle of upper transmission and lower transmission: during upper transmission, the first spur gear (16-16) on the active connecting shaft (16-11) drives the second spur gear (16-17), the second spur gear (16-17) drives the third spur gear (16-18), the third spur gear (16-18) drives the fourth spur gear (16-19), the fourth spur gear (16-19) drives the fifth spur gear (16-20), the fifth spur gear (16-20) drives the second driven connecting shaft (16-9), and at the same time, the third sprocket (16-8) rotates through the first chain (16-4) to drive the first sprocket (16-1) and the first driven connecting shaft (16-2) to rotate, thus forming the upper transmission.

[0036] During the lower layer transmission, the first spur gear (16-16) on the active connecting shaft (16-11) drives the second spur gear (16-17), the second spur gear (16-17) drives the third spur gear (16-18), the third spur gear (16-18) drives the fourth spur gear (16-19), the fourth spur gear (16-19) drives the third driven connecting shaft (16-21), and the fourth sprocket (16-22) rotates, and the fifth sprocket (16-23) and the first driven connecting shaft (16-2) are driven to rotate through the second chain (16-14), thus forming the lower layer transmission.

[0037] The upper and lower layers form transmission in forward and reverse directions.

[0038] The working principle of the device is as follows: the upper and lower layers work together. The lower layer is composed of the front lodging front foot (15), the scissor mechanism (4), and the rice-supporting arm (16) to transmit the material to the lower transmission mechanism (6), the roller cutter room (9) of the material collection box, and the four supporting column screw lifting mechanism (1) that can be raised and lowered. The upper layer is composed of the middle rice chain mechanism (3), the upper transmission mechanism (1), and the wheel scissor mechanism (2). The height is controlled by the screw lifting mechanism (13), and the total power of the device comes from the engine of the harvester.

[0039] Before harvesting crops, if the height of the crops is lower than 600 mm, the upper cutting platform is raised by the screw lifting mechanism (13). When the operation starts, the front foot (15) of the lodging machine first slightly lifts the fallen stalks to the height where the straw-supporting arm (16) grabs the crops, and at the same time, the scissors of the scissor mechanism (4) cut the crops (the height from the ground to the scissor mechanism (4) is 150 mm). The front straw-supporting arm (16) clamps the roots of the crops (the height of the straw-supporting arm is 200 mm from the ground to the crops), and at the same time, the scissors of the scissor mechanism (4) cut the crops. Under the reciprocating action of the straw-supporting arm (16) and the scissor mechanism (4), the materials are transferred to the roller chamber (9) through the lower transmission mechanism (6), and the roller chamber (9) cuts the materials into pieces and throws them into the bridge transmission to enter the threshing system.

[0040] Before harvesting, if the crop is higher than 600 mm, the upper cutting table is first lowered through the screw lifting mechanism (13) to cover the lower transmission mechanism (6). After the machine is started, the lower straw arm (16) and the middle straw chain mechanism (3) clamp the crop at the same time, and the lower scissor mechanism (4) cuts the crop. While the middle straw chain mechanism (3) clamps the crop, the wheel scissor mechanism (2) separates the seed ears from the straw. The seed ears are transmitted to the roller cutter chamber (9) through the upper transmission mechanism (1), and the middle straw chain mechanism (3) sends the straw into the baling system.

[0041] For crops higher than 600 mm, the upper and lower layers are harvested together. For crops lower than 600 mm, the upper layer is raised and the lower layer is harvested alone.
