DETAILED DESCRIPTION

[0015] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A straw cutting, gathering, picking up and conveying combined operation platform for a baler, wherein a cutting and gathering motor 2 is fixedly mounted on the front upper end of a Π-shaped frame stand 7 through a transverse support beam 17, a circular step groove plate 9 is suspended and installed coaxially at the lower side of the transverse support beam 17 and located below the cutting and gathering motor 2, a drive shaft 10 installed at the lower end of the motor shaft of the cutting and gathering motor 2 is inserted into the center hole of the circular step groove plate 9 in an axial and radial positioning and circumferentially rotatable manner, a circular seat plate 11 is fixed coaxially at the lower part of the drive shaft 10 located below the circular step groove plate 9, a plurality of cutter shafts 13 are inserted uniformly in the circumferential direction and axially and radially positioned and circumferentially rotatable on the circular seat plate 11, a crank shaft 9 is fixedly mounted on the inner end face of the cutter shaft 13, a roller 18 is rotatably mounted on the crank shaft 19, and the roller 18 is configured to be rollably snap-fitted on the circular step groove plate 9. In the annular stepped groove of the step groove plate 9, there are fixed circular saw blade cutting knives 14 and elastic gathering nail teeth 12 on the knife tooth shaft 13, which are staggered and arranged at an angle in the circumferential direction; a strip collecting side plate 16 is installed on the inner wall surface of the right side wall plate of the Π-shaped frame stand 7; on the inner wall surface of the rear wall plate of the Π-shaped frame stand 7, at the rear part of the strip collecting side plate 16 and the knife tooth shaft 13, a two-way spiral conveying auger 1 and a spring-tooth picking roller 15 are respectively installed parallel to each other from top to bottom and rotatably, the driving sprocket 4 and the driven sprocket 5 are respectively fixed on the two-way spiral conveying auger 1 and the spring-tooth picking roller 15, the chain 3 is mounted on the driving sprocket 4 and the driven sprocket 5, and the picking and conveying motor 6 fixed on the inner wall surface of the rear wall plate of the Π-shaped frame stand 7 is connected to the two-way spiral conveying auger 1; walking support wheels 8 are respectively rotatably installed on the lower outer parts of the left and right side wall plates of the Π-shaped frame stand 7.

[0016] When in use, the combined workbench is mounted on the front end of the baler using a Π-shaped frame stand 7. With the walking support wheels 8 in contact with the ground, the platform moves forward with the traction power machine, and simultaneously starts the cutting and gathering motor 2 and the picking and conveying motor 6. The cutting and gathering motor 2 drives a plurality of tooth shafts 13 to revolve around the axis of the driving shaft 10 via the driving shaft 10 and the circular seat plate 11. When the circular saw blade cutter 14 on the tooth shaft 13 completes the straw cutting operation standing on the field land, the circular stepped groove plate 6 is fixed on the ground. The roller 18 moving in the circular stepped groove produces an inclined rotation, and the inclined rotating roller 18 drives the blade shaft 13 to rotate on the circular seat plate 11 through the crank shaft 19, so that the circular saw blade cutter 14 that has completed the cutting operation rotates upward and disengages from the ground. At the same time, the elastic collection spikes 12 rotate downward to move the cut straw to the collection side plate 16, and then the picking and conveying motor 6 drives the rotating elastic tooth picking roller 15 to pick up and the bidirectional spiral conveying auger 1 to the baling mechanism at the rear side to complete the baling operation. The blade shaft 13 repeatedly swings in the circumferential direction through the roller 18 and the crank shaft 19 under the control of the circular stepped groove plate 9, completing the sequential and continuous conversion of the working position and the non-working position of the circular saw blade cutter 14 and the elastic collection spikes 12, that is, the conversion of the straw cutting and collecting operations.
