[0054] Embodiment 2:
[0055] A use method of a full-automatic combing and shearing type citrus fruit picking machine, comprising the following steps:
[0056] Step one: when the machine travels to the middle position of the citrus tree, the machine drives the sliding block 205 and the same remaining three sliding blocks to go up, thereby driving all the combing and shearing type picking execution devices 20 except the guide rail to go up;
[0057] Step two: when the shearing type picking device 20 reaches the top of the citrus tree, the servo push rod 206 pushes the picking device close to the tree crown. At this time, the DC motor 220 drives the transmission shaft 209 to rotate, thereby driving the drum 211 and each pair of double-blade shearing knives 216 on the drum 211 to start rotating around the drum 211. When the citrus contacts a pair of double-blade shearing knives 216, the double-blade shearing knives 216 will rotate around their respective rotation axes 217 along the direction of the push force exerted by the citrus on the double-blade shearing knives 216 under the action of the reaction force of the citrus itself and the rotating motion driven by the drum 211. The blade end close to the rotation axis 217 closes to realize the shearing of the citrus stem. Since each group of shearing knives works independently and does not interfere with each other, only the shearing knife group that contacts the citrus will perform the shearing action, and the remaining shearing knife groups that do not contact the citrus remain in the reset state to facilitate the smooth passage of the side branches of the citrus tree and reduce the damage caused by the device to the citrus tree;
[0058] Step three: the drum 211 rotates in the rotation direction 230, so under the action of combing, the stem enters between the two blades, and the citrus is limited in size and size between the flat blades. With the rotation of the drum 211, the citrus will exert a reaction force on the blades, forcing the blades to rotate along the rotation axis 217 until the two blades close to cut off the citrus stem;
[0059] Step four: at the same time, the arc combing and shearing of the citrus tree is completed under the combined action of the guide rail sliding table, the servo motor and the DC motor;
[0060] Step five: during picking, the electric push rod in the controllable collection baffle component 30 moves, adjusts the collection box expansion plate 307 to the appropriate angle, and the picked citrus rolls into the collection box under the action of the collection box expansion plate 307. After picking is completed, continue to travel to the next citrus tree to be picked;
[0061] Step six: after the picking of a citrus tree is completed, steps one to five are repeated to complete the picking of all citrus trees.
[0062] The working principle of the present application is as follows:
[0063] The full-automatic combing and shearing type citrus fruit picking machine is based on a gantry frame, so as to realize crossing a single citrus tree. The combing and shearing type picking execution device 20 is distributed on both sides of the gantry frame. When the machine travels to the middle position of the citrus tree, the slide block 205 and the same remaining three slide blocks are driven upward, so as to drive all the combing and shearing type picking execution devices 20 except the guide rail to move upward. After reaching the top position of the citrus tree, the servo push rod 206 and the same remaining servo push rod drive the picking device to approach the tree crown. Further, the DC motor 220 drives the transmission shaft 209 to rotate, so as to drive the cylinder 211 and each pair of double-blade shearing knives 216 on the cylinder 211 to rotate around the cylinder 211. Further, when the citrus contacts a pair of double-blade shearing knives 216 as shown in Figure 6 , under the reaction force of the citrus itself and the rotating motion driven by the cylinder 211, the double-blade shearing knives 216 will rotate around the respective rotating shafts 217 along the direction of the pushing force applied by the citrus to the double-blade shearing knives 216. The blade end close to the rotating shaft 217 is closed, so as to realize shearing of the citrus stem. Since each group of shearing knives works independently and does not interfere with each other, the shearing knife group that performs the shearing action only occurs in the shearing knife group that contacts the citrus, and the remaining shearing knife groups that do not contact the citrus remain in the reset state to facilitate the smooth passing of the side branches of the citrus tree and reduce the damage caused by the device to the citrus tree. Alternatively, as shown in Figure 7 , since the cylinder 211 rotates along the rotating direction 230, under the action of combing, the stem will enter between the two blades as shown in Figure 7 , and the citrus will be limited in size between the flat blades. However, with the rotation of the cylinder 211, the citrus will apply a reaction force to the blades, forcing the blades to rotate along the rotating shaft 217 until the two blades are closed to cut off the citrus stem. At the same time, under the joint action of the guide rail sliding table, the servo motor and the DC motor, the arc combing and shearing of the citrus tree is completed. When picking, the electric push rod in the controllable collecting baffle part 30 moves, adjusts the collecting box expansion plate 307 to the appropriate angle, and the picked citrus will roll to the collecting box under the action of the collecting box expansion plate 307. After picking is completed, continue to travel to the next citrus tree to be picked. In this way, the picking of all citrus trees is completed.

6. A fully automatic comb and cutter type citrus fruit picking machine according to claim 5, characterized in that, The power supply device and the control device (50) comprise a hydraulic pump station (501) installed on the power and control device support plate (104) for providing power for the hydraulic motor, and further comprise a power supply and control cabinet (502) for placing a battery pack and a control circuit.
7. The method of using the fully automatic comb and snip type citrus fruit picking machine according to claim 6, characterized in that, The method comprises the following steps: Step one: when the machine travels to the middle position of the citrus trees, the machine drives the sliding block (205) and the same remaining three sliding blocks to move upwards, thereby driving all the combing and shearing type picking execution devices (20) except the guide rails to move upwards; Step two: after the combing and shearing type picking execution devices (20) reach the top position of the citrus trees, the servo push rod (206) pushes the picking device to approach the tree crown, at this time, the DC motor (220) drives the transmission shaft (209) to rotate, thereby driving the cylinder (211) and each pair of double-blade shearing knives (216) on the cylinder (211) to start rotating around the cylinder (211), when the citrus contacts a pair of double-blade shearing knives (216), the double-blade shearing knives (216) will rotate around the respective rotating shaft (217) along the direction of the pushing force applied by the citrus to the double-blade shearing knives (216) under the reaction force of the citrus itself and the rotating motion driven by the cylinder (211), the blade end close to the rotating shaft (217) is closed, and the shearing of the citrus fruit stem is realized, since each group of shearing knives works independently and does not interfere with each other, only the shearing knife group in contact with the citrus will occur shearing action, and the remaining shearing knife groups not in contact will remain in the reset state to facilitate the smooth passing of the side branches of the citrus trees and reduce the damage caused by the device to the citrus trees; Step three: the cylinder (211) rotates in the rotating direction (230), so under the combing action, the fruit stem will enter between the two blades, and the citrus will be limited in size and restricted between the flat blades, with the rotation of the cylinder (211), the citrus will apply a reaction force to the blades, forcing the blades to rotate along the rotating shaft (217) until the two blades are closed to cut off the citrus fruit stem; Step four: at the same time, the arc combing and shearing of the citrus trees are completed under the joint action of the guide rail sliding table, the servo motor, and the DC motor. Step five: when picking, the electric push rod in the controllable collecting baffle component (30) acts to adjust the collecting box expansion plate (307) to the appropriate angle, and the picked citrus will roll to the collecting box under the action of the collecting box expansion plate (307), and after picking is completed, it continues to travel to the next citrus tree to be picked; Step six: after the picking of a citrus tree is completed, steps one to five are repeated to complete the picking of all citrus trees.
