In this embodiment, the piston rod of the third hydraulic cylinder 524 extends or retracts, causing the rear section 522 of the third conveyor belt to rotate relative to the front section 521 of the third conveyor belt, thereby adjusting the angle between the rear section 522 and the front section 521 of the third conveyor belt. The top side of the third conveyor belt partition 523 is configured as a comb tooth shape, and the bottom side of the third conveyor belt front baffle 511 is also configured as a comb tooth shape. The comb teeth of the third conveyor belt front baffle 511 and the comb teeth of the third conveyor belt partition 523 are staggered. This design allows the third conveyor belt partition to pass smoothly through the third conveyor belt front baffle. It can prevent pineapples from falling off the front end of the third conveyor belt; the partitions of the third conveyor belt are arranged at intervals along the third conveyor belt to block the pineapples and make them transported with the third conveyor belt; the second conveyor belt is driven by a motor and transports pineapples from front to back; the lifting mechanism 55 includes a lifting motor and a screw lifting transmission mechanism; the translation mechanism 56 includes a translation motor and a screw translation transmission mechanism; the lifting mechanism 55 and the translation mechanism 56 adjust the front-to-back position and the vertical position of the third conveyor belt to ensure that the exit end of the second conveyor belt 42 is always above the front section 521 of the third conveyor belt.

[0046] Refer to Figure 2 As shown, the vehicle body 1 includes a frame 11; a first hydraulic cylinder support 111 is provided on the front side of the frame 11, and the first hydraulic cylinder support 111 is connected to the first hydraulic cylinder 37 via a revolute joint; a second hydraulic cylinder support 112 is also provided on the side of the frame 11, and the second hydraulic cylinder support 112 is connected to the second hydraulic cylinder 44 via a revolute joint; the frame 11 also has a translation mechanism mounting platform 114; the translation mechanism 56 is fixed on the translation mechanism mounting platform 114. In this embodiment, a hydraulic station 7 is also installed on the frame 11, and the hydraulic station 7 is connected to the first steering hydraulic motor 2411, the second steering hydraulic motor 2421, the first hydraulic cylinder 37, the second hydraulic cylinder 44, and the third hydraulic cylinder 524 via oil circuits.

[0047] Refer to Figure 2 As shown, the vehicle body 1 also includes a traveling mechanism, which includes a wheel support frame 12 mounted on the bottom side of the vehicle body and a wheel 13 mounted on the wheel support frame 12. A shielding rod 14 is provided on the front side of the wheel 13; the end of the shielding rod 14 is fixed to the wheel support frame 12. In this embodiment, the shielding rod can prevent the leaves of the pineapple tree from blocking the wheel 13.

[0048] The self-propelled pineapple harvesting and collecting machine of this embodiment has the following working process:

[0049] 1. Based on the planting height of different pineapple fields, the height of the harvesting mechanism is adjusted by extending and retracting the piston rod of the first hydraulic cylinder, thereby driving the combing mechanism to the required pineapple harvesting height. Based on the height of the harvesting mechanism, the second conveyor belt is adjusted by extending and retracting the piston rod of the second hydraulic cylinder, ensuring that the outlet end of the first conveyor belt is above the second conveyor belt, guaranteeing that the pineapples can be smoothly transported from the first conveyor belt to the second conveyor belt. Based on the position of the second conveyor belt, the position of the third conveyor belt is adjusted by the third hydraulic cylinder, lifting mechanism, and translation mechanism, ensuring that the outlet end of the second conveyor belt is above the third conveyor belt, and that the outlet end of the third conveyor belt aligns with the slide of the collection basket, guaranteeing that the pineapples can be smoothly transported from the second conveyor belt to the third conveyor belt, and then smoothly transported to the collection basket via the third conveyor belt. Simultaneously, it is necessary to control the vertical distance between the outlet of the first conveyor belt and the second conveyor belt to be not too high, and the vertical distance between the outlet of the second conveyor belt and the third conveyor belt to be not too high, to prevent the pineapples from falling from excessive height and being damaged.

[0050] 2. After the above adjustments are completed, start the cutting drive motor, the first steering hydraulic motor, the second steering hydraulic motor, the first conveyor belt, the second conveyor belt, and the third conveyor belt;

[0051] 3. Start the walking mechanism, the vehicle moves forward, and the combing rollers straighten and pull in the fallen pineapple tree. The pineapple tree enters through the channel between two adjacent combing rollers. The U-shaped groove on the bottom plate holds the pineapple below the neck. The cutting blade cuts from left to right 5cm below the neck of the pineapple. The cut pineapple tree passes under the guide plate, and the harvested pineapple enters the bottom plate area. It is then conveyed from right to left by the first set of rollers, and then from left to right behind the first set of conveying mechanisms. When the pineapple reaches... When the pineapple reaches the second guiding conveyor, the second guiding roller assembly pulls the pineapple out of the conveying range of the first guiding conveyor and onto the first conveyor belt. The pineapple then falls from the first conveyor belt into the second conveyor belt, which, through the second conveyor belt partition, carries the pineapple backward and upward. The pineapple then falls from the second conveyor belt into the third conveyor belt, which, through the third conveyor belt partition, carries the pineapple backward and upward. Finally, the pineapple falls from the third conveyor belt into the collection basket via a chute, thus completing the entire pineapple harvesting and collection process.

[0052] The above embodiments should not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent conversion fall within the protection scope of the present invention.
