[0002] "Chaotian pepper" is a general term for peppers whose fruits grow upward (upward or at an angle). This classification, based on the fruit placement, includes four of the five cultivated varieties of pepper in plant taxonomy: cluster pepper, cone pepper (small fruit), long pepper (short finger shape), and cherry pepper. Chaotian peppers are often cultivated on large scales, making manual harvesting inefficient and requiring a harvesting device.

[0003] However, the existing chili pepper picking device with a straw cleaning mechanism still has certain problems when in use:

[0004] The existing Chinese patent application number CN202122698062.2 is a chili pepper picking machine, which includes a body, a trapezoidal protective shell is provided on one side of the outer wall of the body, and a bracket pulling device is provided on the lower surface of the inner wall of the trapezoidal protective shell, and the bracket pulling device includes two first motors, and a first driving shaft is provided in the interface on the upper surface of the housing of each of the first motors, and a screw rod is provided at the upper end of each of the first driving shafts, and a ball bearing is provided at the upper end of each of the screw rods, and a connecting shaft is provided at the upper end of each of the ball bearings, and the upper end of each of the connecting shafts is connected to the upper surface of the inner wall of the trapezoidal protective shell, and a nut seat is provided on each of the screw rods, and a transmission rod is provided on one side of the outer wall of each nut seat, and a rectangular slider is provided at the end of each of the transmission rods away from the nut seat;

[0006] Existing mechanized planting usually waits until most of the chili peppers are mature before picking them. However, the chili pepper stalks left after mechanized picking cannot be processed simultaneously with the existing equipment during picking, and further processing is required later. The operation is cumbersome and labor-intensive.

[0007] In response to the above problems, an innovative design was carried out based on the original chili pepper picking device with a straw cleaning mechanism. Summary of the Invention
