The shifting assembly and the multiple straw wheels 37 can transport the cut rapeseed, so that the rapeseed can move inside the channel formed between the transverse mounting plate 17 and the multiple straw supports 38, so that the cut rapeseed can be spread on the field on one side of the reaper, realizing the cutting and drying of the rapeseed, and at the same time, the cut rapeseed can be placed in an orderly manner, completing the entire rapeseed cutting, transportation and laying process.

[0041] like Figure 1-Figure 8As shown, the telescopic assembly includes a U-shaped frame 29, a turntable 30, a hinged rod 31, a second motor 32 and a stepless speed change assembly 33. The turntable 30 is rotatably arranged on the vertical mounting plate 26, the U-shaped frame 29 is fixedly mounted on one side of the vertical moving knife 28, one end of the hinged rod 31 is hinged to the surface of the U-shaped frame 29, and the other end of the hinged rod 31 is hinged to the surface edge of the turntable 30. The second motor 32 is fixedly mounted on the vertical mounting plate 26, and the output end of the second motor 32 is connected to the turntable 30 through the stepless speed change assembly 33;

[0042] When it is necessary to cut the rapeseed, the second motor 32 is controlled to work. The second motor 32 can drive the turntable 30 to rotate through the stepless speed change assembly 33. When the turntable 30 rotates, it can drive the vertical movable knife 28 to move back and forth up and down on the vertical mounting plate 26 through the hinge rod 31. At the same time, in conjunction with the fixed vertical fixed knife 27, it can achieve cutting of the entangled rapeseed branches, which can improve the adaptability of the rapeseed combine harvester to tall rapeseed plants.

[0043] like Figure 1-Figure 8 As shown, the transmission assembly includes an L-shaped connecting rod 39, a first push rod 40, a first wedge block 41, a second wedge block 42, an L-shaped limiting rod 43, a second push rod 44 and a spring 45;

[0044] The L-shaped connecting rod 39 is fixedly mounted on the bottom end of the vertical movable knife 28, the first push rod 40 is fixed on the bottom end of the L-shaped connecting rod 39, the first wedge block 41 is fixed on the bottom end of the first push rod 40, the second push rod 44 is fixedly mounted on the side of the horizontal movable knife 35 close to the first wedge block 41, the L-shaped limiting rod 43 is fixedly mounted on the horizontal mounting plate 17, the other end of the second push rod 44 passes through the L-shaped limiting rod 43 and is fixedly connected to the second wedge block 42, the second push rod 44 and the L-shaped limiting rod 43 are slidably connected, the second wedge block 42 and the surface of the first wedge block 41 are fitted, the spring 45 is sleeved on the second push rod 44, and the two ends of the spring 45 are respectively connected to the L-shaped limiting rod 43 and the second wedge block 42;

[0045] In the initial state, the spring is in a compressed state, and the vertical movable knife 28 is moved to the lowest position. When the driving assembly is working, it can drive the vertical movable knife 28 to reciprocate vertically. When the vertical movable knife 28 moves upward, the vertical movable knife 28 drives the first wedge block 41 to move upward through the L-shaped connecting rod 39 and the first push rod 40. By utilizing the inclined surfaces of the first wedge block 41 and the second wedge block 42, the second wedge block 42 can be driven by the spring 45 to move in a direction away from the second push rod 44 and always fit with the surface of the first wedge block 41. When the second wedge block 42 moves, it can drive the horizontal movable knife 35 to move in a direction close to the first wedge block 41 through the second push rod 44;

[0046] Similarly, when the vertical movable knife 28 moves downward, it can push the transverse movable knife 35 to move toward the side away from the first wedge block 41, that is, when the vertical movable knife 28 reciprocates vertically, it can drive the transverse movable knife 35 to reciprocate horizontally. By setting a transmission component, the vertical movable knife 28 can drive the transverse movable knife 35 to reciprocate horizontally while reciprocating vertically, that is, the work of two cutting knives can be realized through one driving component, which is beneficial to reduce the number of driving sources used in the present mower and reduce power consumption, thereby helping to reduce costs and meet usage requirements.

The two sprockets 20 are symmetrically rotatably arranged on the transverse plate 19. The chain 21 is sleeved on the two sprockets 20. The plurality of shifters 36 are equidistantly fixed on the surface of the chain 21. It should be noted that;

[0048] When the rapeseed is being cut and dried, the driving assembly is controlled to work, and the driving assembly can drive one of the sprockets 20 to rotate, so that the chains 21 on the two sprockets 20 can be driven, thereby driving the multiple reed plows 36 on the surface of the chain 21 to drive, so as to realize the transportation of the cut rapeseed;

[0049] It should be noted that the two shifting assemblies located in the two-strip grooves 18 correspond to the two layers of reel wheels 37 arranged up and down, and can shift the lower part of the rapeseed. The shifting assembly located above the transverse mounting plate 17 can shift the upper part of the rapeseed, thereby stably transporting the cut rapeseed and effectively avoiding rapeseed blockage.

The second bevel gear 24 is located on one side of the first bevel gear 23 and meshes with the first bevel gear 23. When the rapeseed is cut, the first motor 25 is controlled to work, and the first motor 25 can drive the second bevel gear 24 to rotate. Since the second bevel gear 24 and the first bevel gear 23 are meshed with each other, when the second bevel gear 24 rotates, the first bevel gear 23 can be driven to rotate, so that one of the sprockets 20 in each group of the toggle assembly can be driven to rotate through the connecting shaft 22, so that the synchronous operation of the three groups of toggle assemblies can be achieved.

[0051] like Figure 1-Figure 8 As shown, the rotating assembly includes a cylinder 47, a connecting frame 15 and a fixing frame 16.

The bottom end of the fixing frame 16 is hinged to the connecting frame 15, the fixed end of the cylinder 47 is hinged to the connecting plate 14, and the output end of the cylinder 47 is hinged to the top end of the fixing frame 16.

[0052] When it is necessary to adjust the angles of the cutting mechanism and the feeding mechanism, the cylinder 47 is controlled to work. The cylinder 47 can drive the fixed frame 16 to rotate around the hinge axis between the connecting frame 15 and the fixed frame 16 to adjust the angle of the fixed frame 16, thereby adjusting the angles of the cutting mechanism and the feeding mechanism installed on the horizontal mounting plate 17.
