[0050] As shown in Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 16 , a threshing mechanism 3 is arranged below one side of the conveying mechanism 220, and the threshing mechanism 3 is symmetrically arranged in two, and the threshing mechanism 3 is used to remove the leaves of the sunflower stem on the ground.

[0051] The threshing mechanism 3 comprises a rotating frame 310 and a flexible rod 311, the rotating frame 310 is rotatably arranged at the bottom of the vehicle frame 110, and one end of the rotating frame 310 is provided with a rotating shaft in transmission connection with the rotating shaft of the conveying mechanism 220; a plurality of flexible rods 311 are fixed on the side wall of the rotating frame 310 in a staggered manner, and a threshing drive 312 is arranged at the bottom of the vehicle frame 110 to drive the rotating frame 310 to rotate.

[0052] When the rotating frame 310 of the threshing mechanism 3 rotates, the leaves of the sunflower stem on the ground are threshed by the flexible rod 311, which is made of a metal rod, a chain or a rope. The sunflower stem on the ground is relatively hard, so it will not be bent by the threshing.

[0053] The pressure plate mechanism 230 includes a fixed frame 231, a fixed guide plate 232, a movable guide plate 233, a guide rod channel 234, a pressure plate cylinder 235 and a pressure plate 236. A fixed frame 231 is arranged on the rear end of the conveying mechanism 220, and a fixed guide plate 232 is arranged on the inner side of the fixed frame 231. The fixed guide plate 232 is fixed to the conveying mechanism 220, and a movable guide plate 233 is arranged on the top of the fixed guide plate 232 through a hinge. A reset spring 237 is arranged on the hinge between the movable guide plate 233 and the corresponding fixed frame 231.

[0054] The fixed guide plate 232 and the movable guide plate 233 are both "L" shaped, and the reset spring 237 is a torsion spring. The reset spring 237 is sleeved on the rotating shaft of the hinge.

[0055] A pressure plate 236 is arranged above the two movable guide plates 233 in parallel with the movable guide plates 233. A pressure plate cylinder 235 is arranged between the top of the pressure plate 236 and the bottom of the vehicle frame 110. The pressure plate cylinder 235 can be a cylinder, an electric push rod or a hydraulic cylinder. In this embodiment, the pressure plate cylinder 235 is a cylinder. The extension end of the pressure plate cylinder 235 is fixed to the top of the pressure plate 236. The pressure plate 236 is lifted and lowered above the movable guide plate 233 by the extension and retraction of the extension end of the pressure plate cylinder 235. The sunflower disc is sent to the fixed guide plate 232 along the conveying mechanism 220 and slides onto the movable guide plate 233. The pressure plate 236 is driven by the pressure plate cylinder 235 to press the sunflower disc on the movable guide plate 233, so that the sunflower disc is inserted into the top end of the sunflower stem on the ground. The movable guide plate 233 is reset by the reset spring 237 after being turned downward. A guide rod channel 234 is arranged below the rear end of the fixed frame 231 and arranged in the direction of travel of the vehicle frame 110. The guide rod channel 234 is arranged directly below the pressure plate 236. The guide rod channel 234 is a "Y-shaped" channel composed of a pair of guide plates. The opening of the guide rod channel 234 faces the direction of travel of the vehicle frame 110. When the walking vehicle 1 travels, the sunflower stem on the ground enters the guide rod channel 234 from the opening, is limited by the guide rod channel 234 and is straightened, which facilitates the insertion of the sunflower disc.

[0056] The gap between the two movable guide plates 233 can avoid the collision of the sunflower stem tip and prevent the damage of the sunflower stem tip, which can avoid the failure of the sunflower disc.

[0057] The front baffle 238 and the rear baffle 239 are respectively fixed above the front end and below the rear end of the pressure disc 236. Since the sunflower disc slides along the fixed frame 231, the front baffle 238 can block the next sunflower disc from entering and make it stay on the fixed guide plate 232 during the current sunflower disc inserting operation on the movable guide plate 233, and the rear baffle 239 blocks the front sunflower disc from sliding and shifting.

[0058] A detection device 4 for detecting the sunflower stem is arranged on one side of the guide rod channel 234. The detection device 4 is connected with the input end of the controller 5, and the output end of the controller 5 is connected with the pressure disc cylinder 235. The detection device 4 can be a contact sensor or an infrared sensor, etc. In this embodiment, the contact sensor is selected. The contact rod of the detection device 4 contacts the sunflower stem on the ground entering the guide rod channel 234. The controller 5 starts and drives the pressure disc cylinder 235 to press down the pressure disc 236, and the sunflower disc is just inserted at an inclined angle on the sunflower stem on the ground. The position of the detection device 4 on one side of the guide rod channel 234 can be adjusted horizontally through bolts and nuts. The purpose is to control the detection time of the detection device 4 in order to control the inclined angle of the sunflower disc inserting. For example, if the detection device 4 is installed in front, the sunflower stem on the ground is detected too early. At this time, the sunflower disc is in an inclined state. If the detection device 4 is installed at the rear, the sunflower stem on the ground is detected too late. At this time, the sunflower disc is in a small amplitude inclined state or even a horizontal state due to the sunflower stem tip.

[0059] As shown in Figure 14 , Figure 15 The power mode of the sunflower harvesting and inserting disc machine in this embodiment is realized by the driving device of the walking vehicle 1. In this embodiment, the driving device is selected as an engine. The transmission rod of the engine provides power output, which is transmitted to the input end of the auger drive 2181, the input end of the cutting drive 2131 and the input end of the cutting roller drive 217 through the chain wheel and chain.

[0060] The cutting roller drive 217 has a pair of output ends in the longitudinal direction at the top, which are coaxially fixed with the chain wheel of the chain mechanism 212 and the two groups of cutting chain wheels of the cutting drive 2142.

[0061] The input end of the threshing drive 312 is transmitted to the rotating shaft of the conveying mechanism 220 through the chain and chain wheel.
