At the same time, after the existing mulberry strip harvester adjusts the header height, in order to ensure smooth connection between harvesting and conveying operations, it is also necessary to adjust the conveying device for conveying mulberry strips to adapt to the height of the header. The adjustment process requires professional operators to implement, and the operation is complicated and the operation efficiency is low. Summary of the invention

[0023] like Figure 3 As shown, the cutting platform lifting device 2 includes a lifting float 21, a lifting slide rail 24, a hydraulic cylinder 25 and a connecting part 26. The lifting float 21 is slidably connected to the lifting slide rail 24. A rectangular groove structure is provided on the inner side of the lifting slide rail 24. The lifting float 21 is movably inserted into the rectangular groove structure of the two lifting slide rails 24 through sliders 42 on both sides to achieve the limitation and guidance of the lifting float 21. The cylinder body and telescopic rod of the hydraulic cylinder 25 are respectively connected to the main machine assembly 1 and the lifting float 21. The hydraulic cylinder 25 adjusts the up and down height of the cutting platform device 3 through the action of the telescopic rod. The lifting float 21 is connected to the cutting platform device 3 through the connecting part 26.

[0024] Furthermore, in order to limit the tilting tendency of the lifting float 21 to the sides and front and back directions during the lifting and lowering process of the hydraulic cylinder 25 and to reduce the friction force of the lifting float 21 during the lifting and lowering process, a side limiting pulley 22 and a front limiting pulley 23 are provided on the lifting float 21, and the side limiting pulley 22 and the front limiting pulley 23 are in sliding contact with the front and side of the lifting slide rail 24 respectively.

[0027] like Figure 5 As shown, the main engine assembly 1 includes a frame 11 and an engine 12 installed on the frame 11, a total output shaft 13, a cutting platform power input shaft 14, a right-angle gearbox 15 and a stacking power input shaft 16, the output shaft of the engine 12 is transmission-connected with the total output shaft 13, the total output shaft 13 is transmission-connected with the horizontal input shaft of the right-angle gearbox 15 and the cutting platform power input shaft 14 through a pulley assembly, the cutting platform power input shaft 14 is transmission-connected with the cutting platform device 3, the vertical output shaft of the right-angle gearbox 15 is transmission-connected with the conveying device 5 through the main engine connecting device 6, and the stacking power input shaft 16 is transmission-connected with the horizontal input shaft of the right-angle gearbox 15 through a pulley assembly.

[0028] During the power output process, the engine 12 first outputs power to the total output shaft 13, and then the total output shaft 13 transmits power to the cutting table power input shaft 14 and the right-angle shaft gearbox 15 through belt transmission at the same time, and then the cutting table power input shaft 14 outputs power to the cutting table device 3, and at the same time the right-angle shaft gearbox 15 transmits power to the power input shaft of the stacking device 7 on the one hand, and transmits power to the stacking device 7 through the power input shaft, and on the other hand, the belt arrangement can be converted from a vertical plane to a horizontal plane, and the rotation direction of the pulley is changed, and the power is transmitted to the conveying device 5 through the main machine connecting device 6; during the power transmission process, the transmission ratio between the various components is changed through the pulley, so that the conveying speed of the conveying device 5 is greater than the conveying speed of the cutting table device 3, so that the mulberry strips can be transported smoothly and avoid blockage; at the same time, the entire transmission system clutch is arranged on the total output shaft 13, so that a clutch control can be realized except for the main machine walking.

[0029] like Figure 6As shown, the main engine connecting device 6 includes a connecting base plate 61, a conveying power input shaft 62, a vertical support 63, a pin 64, an upper fixed plate 65 and a relay transmission assembly 66. The connecting base plate 61 is fixedly connected to the frame 11 of the main engine assembly 1, the vertical support 63 is fixedly connected to the connecting base plate 61, the upper fixed plate 65 is fixedly connected to the rear end of the conveying device 5, and is rotatably connected to the vertical support 63 through the pin 64, the conveying power input shaft 62 and the relay transmission assembly 66 are installed on the connecting base plate 61, the conveying power input shaft 62 is transmission-connected to the relay transmission assembly 66 through an intermediate sprocket and a chain, and the relay transmission assembly 66 is transmission-connected to the output shaft of the right-angle gearbox 15 through a pulley assembly.

[0030] The main engine connection device 6 is used to transmit power to the conveying device 5. At the same time, the cutting platform device 3 can be used as a rotation fulcrum at the rear of the conveying device 5 when it is raised or lowered, so that the rear end outlet of the conveying device 5 is adapted to the stacking device 7.

[0031] like Figure 7 , Figure 8 As shown, the conveying device 5 includes a supporting frame 51, a shifting gear chain assembly 52, a conveying sprocket 53, an upper baffle plate 54, a lower baffle plate 55, a guide plate 56, a spring 57, a grain pressing tube 58 and a bottom supporting plate 59. A plurality of sprockets are horizontally rotatably connected in the middle part of the supporting frame 51. The shifting gear chain assembly 52 is transmission-connected with a plurality of conveying sprockets 53. The shifting gear chain assembly 52 includes a chain and a plurality of shifting teeth uniformly fixed on the chain. The upper baffle plate 54 and the lower baffle plate 55 are respectively fixed at the upper and lower parts of the supporting frame 51. The guide plate 56 is fixed at the middle part of the supporting frame 51 and is away from the outer sides of the upper baffle plate 54 and the lower baffle plate 55. The side of the guide plate 56 close to the upper baffle plate 54 and the lower baffle plate 55 is connected to the grain pressing tube 58 through a plurality of springs 57. The bottom supporting plate 59 is fixedly connected to the bottom of the supporting frame 51 close to the outer side of the lower baffle plate 55. The conveying sprocket 53 at the rear end is transmission-connected with the conveying power input shaft 62 to realize the input of power.

[0032] Furthermore, in order to facilitate the accurate delivery of the mulberry branches transmitted by the conveying device 5 to the stacking device 7, a horizontally arranged reel 510 is provided at the rear end of the supporting frame 51, and a plurality of evenly distributed reel teeth are provided on the reel 510.

[0033] The working process of the present invention is as follows: when in use, after starting the main machine assembly 1, the machine is moved to a suitable position, and the header device 3 is adjusted to a suitable harvesting height by adjusting the hydraulic cylinder 25, and then the header device 3, the conveying device 5 and the stacking device 7 are started by the clutch control of the total output shaft 13. When working, the header device 3 first vertically transmits the harvested mulberry strips to the entrance of the conveying device 5, and the mulberry strips vertically enter the gap between the straw pressing tube 58 and the upper baffle 54 and the lower baffle 55, and are bent outward by the guide plate 56 and the straw pressing tube 58 to expand the entrance to facilitate the entry of the mulberry strips. When the mulberry strips enter the gap between the straw pressing tube 58 and the upper baffle 54 and the lower baffle 55, the straw pressing tube 58 presses the mulberry strips against the gap under the action of the elastic force of the spring 57. On the outer walls of the upper baffle 54 and the lower baffle 55, the bottom support plate 59 supports the bottom of the mulberry sticks to keep the mulberry sticks in a vertical state. At this time, the conveying sprocket 53 drives the tooth chain assembly 52 to move. During the movement, when the teeth of the tooth chain assembly 52 move to the mulberry stick position, the mulberry sticks are moved along the direction of the guide plate 56 and the straw pressing tube 58. When the mulberry sticks are pushed to the rear end of the conveying device 5, they enter the straw teeth of the straw wheel 510. Under the guidance of the straw wheel 510, the mulberry sticks are accurately transmitted to the stacking device 7. The mulberry sticks will be stacked in the stacking device 7, and the number of stacked mulberry sticks will be sensed by the sensor in the stacking device 7. When the stacking amount of mulberry sticks reaches the set standard, the fork assembly of the stacking device 7 will be triggered to remove the stacked mulberry sticks.
