[0019] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0020] This utility model embodiment provides a tall-pole crop harvester, combined with... Figure 1 and Figure 2 As shown, the device includes a vehicle body (not shown) and a harvesting guide device. The harvesting guide device is vertically movable and connected to the front of the vehicle body. The harvesting guide device includes a drive device (not shown), a gathering component, a cutting disc 2, a first guide component 3, and a baffle 4. The drive device connects the cutting disc 2 and the first guide component 3 to provide power. The gathering component is fixed in front of the baffle 4 and gathers the messy tall crops towards the center. The cutting disc 2 is located at the bottom center of the baffle 4 and cuts the ends of the tall crops. The first guide component 3 is rotatably mounted on the baffle 4 and pushes the cut tall crops to one side.

[0021] The following tall crops, taking sugarcane as an example, are... Figure 1 As shown, in this embodiment, the vehicle body uses a cylinder to push the harvesting guide device up and down, thereby adjusting the cutting and gathering height. The surface of the cutting disc 2 is parallel or nearly parallel to the horizontal plane. The cutting disc 2 has several cutting teeth distributed circumferentially. When the cutting disc 2 rotates, the cutting teeth cut the tips of the sugarcane.

[0022] The gathering component and the cutting disc 2 work together to gather the tall, lush, and messy crops together for harvesting, preventing any missed harvests. The baffle 4 prevents the cut tall crops from falling onto the rear of the vehicle. The first guide component 3 works with the baffle 4 to rotate and guide the harvested tall crops to the same side for easy collection.

[0023] like Figure 1 As shown, optionally, the first guide assembly 3 includes a first transmission chain 31 and two first transmission wheels 32. The two first transmission wheels 32 are connected by the first transmission chain 31. The first transmission chain 31 is provided with a plurality of spaced guide blocks 33. The baffle 4 is provided with an opening 41, and the guide blocks 33 extend out of the opening 41. When the first transmission wheel 32 drives the first transmission chain 31 to rotate, the guide blocks 33 push the cut tall crops to one side.

[0024] In this embodiment, the baffle 4 has three sets of first guide components 3 spaced apart in the vertical direction. The guide block 33 can be a trapezoid or a triangular body, and one side wall of the guide block 33 is fixed to the first transmission chain 31. When the sugarcane needs to be tilted to the left, the two first transmission wheels 32 drive the first transmission chain 31 to rotate clockwise together, causing the guide block 33 extending from the outlet to move to the left, so as to push the sugarcane to the left; when the sugarcane needs to be tilted to the right, the two first transmission wheels 32 drive the first transmission belt to rotate counterclockwise together, causing the guide block 33 extending from the outlet to move to the right, so as to push the sugarcane to the right.

[0025] like Figure 1 As shown, optionally, the gathering assembly includes two guide rods 1 spaced apart on the left and right. The bottom of the guide rods 1 protrudes forward and forms a tip 11. The tip 11 is used to insert into the tall crops. A gathering space is formed between the two guide rods 1. The cutting disc 2 is located at the bottom of the gathering space to cut the gathered tall crops.

[0026] In this embodiment, as the vehicle moves forward, the tip 11 can first insert into the roots of the sugarcane clump from the bottom, thereby diverting and gathering the dense crop.

[0027] like Figure 1 As shown, optionally, the harvesting guide device includes a second guide component and a connecting frame 6. The connecting frame 6 is fixedly connected to the bottom of the baffle 4. The gathering component and the second guide component are both disposed on the connecting frame 6. An avoidance opening 42 is provided between the connecting frame 6 and the baffle 4. The avoidance opening 42 is used to avoid tall crops after cutting.

[0028] In this embodiment, the clearance opening 42 is located on the right side; in other embodiments, it can be located on the left side as needed. The guide crank 1 is fixed to the front end of the connecting frame 6, thereby positioning the tip 11 at the foremost position.

[0029] like Figure 1 As shown, optionally, the second guide assembly includes two turntables 5 spaced apart to the left and right. The turntables 5 are provided with rotating teeth 51 with arc-shaped guide surfaces 52. The turntables 5 rotate to push tall crops to gather and / or guide the tall crops to the avoidance opening 42.

[0030] In this embodiment, the two turntables 5 are symmetrically distributed, and the arc-shaped guide surface 52 is provided on the left or right side wall of the rotating tooth 51. The turntable 5 on the left rotates actively, while the turntable 5 on the right rotates passively. When the left turntable 5 rotates counterclockwise, the sugarcane on the left is pushed between the two turntables 5, cut, and then falls towards the right-side clearance opening 42 under the guidance of the first guide component 3. At this time, the left turntable 5 also provides rightward guidance for the sugarcane, while the right turntable 5 rotates passively under the weight of the sugarcane, further guiding it towards the clearance opening 42. In other embodiments, both turntables 5 can be set to rotate actively.

[0031] like Figure 1 As shown, optionally, the connecting frame 6 is provided with a guide rod 61 and a guide plate 62 at one end near the baffle 4. The axis of the guide rod 61 is located in the left-right direction. The guide rod 61 is located at the front end of the clearance opening 42. The surface of the guide plate 62 is bent downward. The guide plate 62 is located at the bottom of the clearance opening 42 and fixed to the bottom of the connecting frame 6.

[0032] In this embodiment, the guide rod 61 and the baffle 4 restrict the movement direction of the sugarcane from the front and rear directions, and the guide plate 62 guides the sugarcane from the bottom to smoothly carve out the avoidance opening 42.

[0033] like Figure 2 As shown, optionally, a first transmission rod 7 is fixedly connected to the drive shaft of the drive device. The first transmission rod 7 is connected to the cutting disc 2 and drives the cutting disc 2 to rotate. The first guide assembly 3 includes a second transmission rod 8, a second transmission chain 81, and two second transmission wheels 82. The two second transmission wheels 82 are connected by the second transmission chain 81. The two second transmission wheels 82 are respectively disposed on the first transmission rod 7 and the second transmission rod 8.

[0034] like Figure 1 and Figure 2As shown, optionally, the second guide assembly includes a third transmission rod 9, a third transmission chain 91, and two third transmission wheels 92. The two third transmission wheels 92 are connected by the third transmission chain 91, and the two third transmission wheels 92 are respectively disposed on the second transmission rod 8 and the third transmission rod 9.

[0035] In this embodiment, the driving device is a motor. The first transmission rod 7 connects to three first guide components 3 simultaneously. Through a single driving device, driving force is provided to the first guide components 3, the second guide components, and the cutting disc 2 at the same time, saving the number of driving devices required and significantly reducing costs.

[0036] like Figure 1 As shown, optionally, the connecting frame 6 is provided with a protective rod 63, which extends to the left or right side of the baffle 4. The protective rod 63 is used to protect the third transmission chain 91 to prevent tall crops from getting stuck in the third transmission chain 91.

[0037] In this embodiment, the protective rod 63 is located on the left side to protect the third transmission chain 91 located on the left side. The protective rod 63 pushes aside the sugarcane bushes to prevent branches from getting stuck in the third transmission chain 91.

[0038] Optionally, the harvesting guide device is equipped with a vision sensor (not shown), which is used for tracking and obstacle avoidance and / or locating the cutting point of tall crops.

[0039] Equipped with visual sensors to assist in tracking and obstacle avoidance, and with an auxiliary harvesting guide device to adjust the cutting position vertically, it can adapt to complex terrain environments with uneven terrain. In this embodiment, visual sensors can also be installed on the vehicle body to assist in tracking and obstacle avoidance.
