It can be used for ecological restoration and has high economic value. However, the planting technology of apocynum venetum is not standardized. Restricted by problems such as water resources in arid areas and low harvesting efficiency, the industrial development of apocynum venetum faces huge challenges, seriously restricting the sustainable development of the apocynum venetum industry.

[0010] In Figures 1 - 9 ​​​​​In the illustrated embodiment: The frame body 11 of the header frame 1 has a planar frame structure. A plane passing through the center of the long border of the frame plane of the frame body 11, perpendicular to the long border, and perpendicular to the frame plane is defined as the symmetry plane of the header frame 1. After a middle part of one long border of the planar frame of the frame body 11 is disconnected, U-shaped guard plates 12 are installed on the outer sides of the two sections of the planar frame to prevent entanglement of crop straws, branches and leaves such as apocynum venetum. On two short borders of one frame plane of the frame body 11, lifters 13 extend in a direction perpendicular to the frame plane of the frame body 11 to straighten and guide crop straws such as apocynum venetum to be in an upright and stable state, facilitating subsequent cutting. On the frame plane of the frame body 11 on the side away from the lifters 13, a side output deflector 14 is installed to guide crop straws such as apocynum venetum that are fed into and pass through the middle of the planar frame of the frame body 11 to be conveyed to one side, facilitating subsequent baling operations. The header frame 1 is hung in front of a power device such as a tractor through the frame plane of the frame body 11 on the side away from the lifters 13, and the long border after the planar frame of the frame body 11 is disconnected is located above. The height position of the header frame 1 relative to a power device such as a tractor is adjustable and can swing around the longitudinal axis of a power device such as a tractor. Multiple fixed knives 21 of the cutting assembly 2 are installed on the frame plane of the frame body 11 of the header frame 1 on the side where the lifters 13 extend and at the long border close to the ground. The plane where the multiple fixed knives 21 are located is perpendicular to the frame plane of the frame body 11 and parallel to the long border of the frame plane of the frame body 11. The knife bar 23 equipped with multiple moving knives 22 is slidably installed on the side close to the center of the frame plane of the frame body 11 of the multiple fixed knives 21. The cutting plane of the multiple moving knives 22 is attached to the cutting plane of the multiple fixed knives 21, and the length direction of the knife bar 23 is parallel to the frame plane of the frame body 11, so as to cut crop straws such as apocynum venetum fed to the moving knives 22 and the fixed knives 21. On the side plate surface of the moving knife 22 away from the fixed knife 21, a connecting rod 24 is installed. One end of the connecting rod 24 close to the end of the knife bar 23 is hinged to a rocker 25, and the other end of the rocker 25 is hinged to the frame plane of the frame body 11 of the header frame 1. A cutting drive 26 with stepless speed change is installed on the frame plane of the frame body 11. A balance eccentric block 27 is installed on the output shaft of the cutting drive 26 to balance the impact and vibration caused by the reciprocating movement of the moving knife 22 and the knife bar 23. One end of a connecting rod 28 is sleeved on the eccentric shaft of the balance eccentric block 27, and the other end is hinged to the middle of the rocker 25. Therefore, the cutting drive 26 can drive the rocker 25 to reciprocate through the balance eccentric block 27 and the connecting rod 28, and further drive the knife bar 23 and the moving knife 22 to reciprocate.The outer diameter of the driving roller 31 of the two-way conveying device 3 is smaller than the inner width of the U-shaped groove of the guard plate 12 of the cutting table frame 1. The two conveying shafts 32, on which three driving rollers 31 are mounted, are respectively supported at the middle parts of the two long side frames of the frame plane of the table frame body 11 of the cutting table frame 1 at both ends, and the two conveying shafts 32 are symmetrically arranged with respect to the symmetry plane of the cutting table frame 1. The stepless variable-speed conveying drive 33 is installed on the frame plane of the table frame body 11. The output shaft of the conveying drive 33 is connected to one end of the drive shaft 34, and the other end of the drive shaft 34 is supported on the frame plane of the table frame body 11. The middle part of the drive shaft 34 is connected to one conveying shaft 32 through a chain drive 35. The extending ends of the two conveying shafts 32 facing the ground, after passing through the long side frame on the side close to the ground of the table frame body 11, are connected through a gear drive 36 and another chain drive 35 to ensure that the two conveying shafts rotate in opposite directions. Three driven rollers 37 with the same outer diameter as the driving roller 31 are supported at the frame plane of the table frame body 11 close to the short side frame. The axes of the three driven rollers 37 are coaxial and are respectively located in the same plane as the three driving rollers 31 mounted on the conveying shaft 32. Another three driven rollers 37 are supported at the frame plane of the table frame body 11 close to the other short side frame. The axes of the three driven rollers 37 are coaxial and are respectively located in the same plane as the three driving rollers 31 mounted on the conveying shaft 32. The annular outer surface of the toothed conveyor belt 38 in a ring shape is provided with a number of teeth along the annular length direction of the toothed conveyor belt 38. Three toothed conveyor belts 38 are respectively hung on the three driving rollers 31 and three driven rollers 37 at the same end of the frame plane of the table frame body 11. Another three toothed conveyor belts 38 are respectively hung on the three driving rollers 31 and three driven rollers 37 at the other end of the frame plane of the table frame body 11. The tight sections of all the toothed conveyor belts 38 face the forward direction of the machine. The teeth of all the toothed conveyor belts 38 extend out of the U-shaped groove of the guard plate 12 after passing through the guard plate 12 of the cutting table frame 1, so as to bidirectionally concentrate and convey the cut crop straws such as apocynum venetum towards the middle of the cutting table frame 1. One auxiliary feeding wheel 39 is installed at the extending end of the drive shaft 34 after passing upward through the long side frame of the table frame body 11. Another auxiliary feeding wheel 39 is installed above the long side frame of the table frame body 11 and is connected to the conveying shaft 32 far from the conveying drive 33 through another chain drive 35, so as to realize combing and dividing and feeding, and effectively avoid the occurrence of the phenomenon that the crop straws such as apocynum venetum deviate from the cutting table due to the fluffy upper branches and leaves and other reasons. The dividing and feeding device 4 has a dividing frame 41 in a planar frame structure. The dividing board 42 is in a triangular shape and one angle is an acute angle. The dividing board 42 is installed on one side of the dividing frame 41, and the board surface of the dividing board 42 is perpendicular to the frame plane of the dividing frame 41. A dividing star wheel 43 is installed on the board surface of the dividing board 42 close to the dividing frame 41. The dividing star wheel 43 is located at the position far from the acute angle of the dividing board 42, and the axis of the dividing star wheel 43 is perpendicular to the board surface of the dividing board 42.The grain pressing and elastic rod I 44 is J-shaped, and the J-shaped head end of the grain pressing and elastic rod I 44 is installed on the end of the axis of a grain-pushing star wheel 43 away from the grain-dividing plate 42, and the grain pressing and elastic rod II 45 is S-shaped, and the end of the grain pressing and elastic rod II 45 away from the S-shape is installed on the end of the axis of another grain-pushing star wheel 43 away from the grain-dividing plate 42; the two grain-pushing and feeding devices 4 are symmetrically installed on the frame body 11 of the cutting frame 1 through the side of the grain-pushing frame 41 close to the grain-pushing star wheel 43, and the grain-pushing frame 41 of the two grain-pushing and feeding devices 4 is equipped with the grain pressing and elastic rod II 45. Both are located in the middle of the frame body 11, all the grain-dividing plates 42 of the two grain-pushing and feeding devices 4 are located in the same plane, the acute angles of the grain-dividing plates 42 are facing the forward direction of the machine, and all the grain-pushing star wheels 43 and the toothed conveyor belt 38 located in the middle of the two-way conveying device 3 are at the same height. During the harvesting process, each straw star wheel 43 is driven and rotated by the tooth conveyor belt 38, so the cut straw of crops such as Apocynum venetum can be driven to the tooth conveyor belt 38, and then evenly pressed between the tight section of the tooth conveyor belt 38 and the straw pressing and elastic rods I 44 and II 45 under the action of the straw pressing and elastic rods I 44 and II 45, and then fed in a two-way centralized manner toward the middle of the cutting platform 1. The baler 51 of the baling device 5 is installed on the frame plane of the frame body 11 of the cutting platform 1 near the straw supporter 13, the guide rope hook 52 is hinged at the end of the side output guide plate 14 of the cutting platform 1, one side of the straw outlet gate 53 is hinged at the outer side of the frame body 11 of the cutting platform 1 near the straw supporter 13, and the other side is buckled at the end of the side output guide plate 14, the straw gate drive 54 is installed on the frame plane of the frame body 11, and the output shaft of the straw gate drive 54 is hinged on the inner plate surface of the straw outlet gate 53. After the stalks of crops such as rhubarb that are fed and pass through the middle of the plane frame of the frame body 11 run to the side output guide plate 14 of the cutting frame 1, they are transported to the baling device 5 on one side of the cutting frame 1 through the loose teeth of the toothed conveyor belt 38 on one side of the two-way conveying device 3 and the guidance of the side output guide plate 14. The baling device 5 collects the stalks of crops such as rhubarb and gradually increases the number of stalks. When the accumulated number of stalks of crops such as rhubarb reaches the set value, the rope hook 52 guides the collected stalks of crops such as rhubarb to pass the rope, and the baler 51 quickly performs baling and tying operations on them. The stalk gate drive 54 quickly starts to open the stalk gate 53, and throws out the baled stalks of crops such as rhubarb after counting.

[0011] Its working principle is as follows: The harvesting platform is connected to power equipment such as tractors. According to the characteristics of different crops such as apocynum venetum to be harvested and the terrain features, the ground clearance and the longitudinal tilt angle of the harvesting platform are adjusted, and the rotational speeds of the cutting drive and the conveying drive are adjusted. When encountering a sloping land with a transverse tilt, the machine can automatically adjust the transverse tilt angle. After the machine runs to the plot to be harvested along with power equipment such as tractors, the cutting drive of the cutting assembly is started, and the cutter bar is driven to reciprocate through a balance eccentric block, a connecting rod and a rocker, and then the moving knife is driven to reciprocate. The conveying drive of the bidirectional conveying device is started, and one conveying shaft and the driving roller are driven to rotate through a driving shaft and a chain drive, and then another conveying shaft and the driving roller are driven to rotate through a gear drive and another chain drive, so as to drive each toothed conveying belt to run; meanwhile, the driving shaft also drives one auxiliary feeding wheel to rotate, and the other auxiliary feeding wheel is driven to rotate by the conveying shaft through another chain drive; in addition, the toothed conveying belt also drives the toothed star wheel of the reaping and feeding device to rotate. The gate drive of the baling device is started, the outlet gate is closed, and the harvesting operation begins.

[0012] As the machine moves forward, the straws of crops such as apocynum venetum enter the cutting edges of the moving knife and the fixed knife of the cutting assembly under the support of the lifters on both sides of the cutting platform frame, and are quickly cut off by the reciprocating moving knife. Due to the equipped balance eccentric block, the impact and vibration are effectively reduced, and the service life of the cutting assembly is extended.

[0013] After being cut off, the straws of crops such as apocynum venetum are shunted and guided by the dividing board of the reaping and feeding device, and are moved towards each toothed conveying belt under the action of the toothed star wheel; then, under the action of the toothed conveying belt of the bidirectional conveying device and the elastic action of the pressing straw spring rod I and the pressing straw spring rod II, they are evenly pressed between the tight section of the toothed conveying belt and the pressing straw spring rod I and the pressing straw spring rod II, and are centrally conveyed bidirectionally towards the middle of the cutting platform frame; the auxiliary feeding wheels installed on the cutting platform frame gather the fluffy branches and leaves on the upper part of the straws of crops such as apocynum venetum together to prevent the straws of crops such as apocynum venetum from deviating from the cutting platform. Therefore, the combing, reaping and feeding, and bidirectional central conveying are smooth, and the operation reliability is high.

[0014] The straws of crops such as apocynum venetum conveyed to the middle of the cutting platform frame pass through the middle break of the long side frame of the platform body, and are guided by the side output guide plate behind the cutting platform frame, and are conveyed to one side of the cutting platform under the reverse conveying action of the loose section of the toothed conveying belt, and then are collected by the baling device; when the accumulated quantity of the straws of crops such as apocynum venetum reaches the set value, the string guiding hook guides the collected straws of crops such as apocynum venetum to pass through the rope, and then the baler quickly performs the baling and tying operation on them; subsequently, the gate drive is quickly started to open the outlet gate, and after counting, the baled straws of crops such as apocynum venetum are thrown out of the machine; afterwards, the gate drive is started in the reverse direction to quickly close the outlet gate.
