[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0025] Example 1:

[0026] like Figure 1As shown, a pineapple terminal bud picking device includes a conveyor 1, a support frame 21, a visual sensor 26, a push plate 9, and a controller 2. The conveyor 1 includes a conveyor belt 18 and a frame 11. The conveyor belt 18 is driven and mounted on the frame 11. The support frame 21 is mounted on the frame 11 across the conveyor belt 18. A cutting drive 4 and a first limit sensor 7 are mounted on one side, and a blocking drive 25 and a second limit sensor 22 are mounted on the other side. The cutting drive 4 is provided with a cutting telescopic rod 41, and the blocking drive 25 is provided with a blocking telescopic rod 251. The visual sensor 26 is mounted on the top of the support frame 21. One end of the push plate 9 is connected to the cutting telescopic rod 41, and the other end is connected to the horizontally mounted cutter 8. The controller 2 is electrically connected to the conveyor 1, the cutting drive 4, the first limit sensor 7, the blocking drive 25, the second limit sensor 22, and the visual sensor 26.

[0027] In order to better support the cutter to cut the pineapple terminal bud, an auxiliary baffle 24 is added. The auxiliary baffle 24 is installed on the support frame 21 corresponding to the cutting drive member 4 and is close to the top surface of the conveyor belt 18.

[0028] like Figure 1 As shown, the cutter 8 is provided with a trapezoidal blade 81, which is tapered inward along the width direction of the cutter 8. This facilitates cutting the pineapple terminal buds.

[0029] It is understandable that, in order for the cutter and the auxiliary baffle to interact and cut the pineapple terminal bud, the width of the conveyor belt 18 is slightly larger than the diameter of the mature pineapple. When the cutter cuts the pineapple terminal bud, the auxiliary baffle can block the pineapple from moving, making it convenient for the cutter to cut the pineapple terminal bud.

[0030] The push plate 9 can make the cutter and the cutting telescopic rod have a gap,

[0031] like Figure 1 As shown, the conveyor 1 also includes an active roller 19, a driven roller 17, a driving motor 13, a support platform 14, a driven wheel 12 and a driving wheel 15. The active roller 19 and the driven roller 17 are each rotatably mounted on one end of the frame 11 and are connected by a conveyor belt 18. The driven wheel 12 is connected to the active roller 19 by transmission. The driving motor 13 is provided with an output shaft 16, and the output shaft 16 is equipped with a driving wheel 15, which is connected to the driven wheel 12 by transmission. The support platform 14 is installed at the bottom of the frame 11 for supporting and installing the driving motor 13.

[0032] A transmission connection structure of the driven wheel 12 and the active roller 19 is as follows: the driven wheel 12 and the active roller 19 are connected via a rotating shaft. The rotating shaft passes through the frame, one end of the rotating shaft is connected to the active roller, and the other end is connected to the driven wheel.

[0033] A transmission connection structure of the driven wheel and the driving wheel is as follows: the driven wheel 12 and the driving wheel 15 are connected to each other through a transmission member 110. The transmission member can be a transmission belt or a chain.

[0034] In order to facilitate the installation of the blocking drive member, a bracket 10 is additionally installed. Figure 1 As shown, the bracket 10 is installed on the support frame 21 for supporting and installing the blocking driving member 25.

[0035] The first limit sensor 7 and the second limit sensor 22 are installed at corresponding intervals to limit the spacing of the reciprocating movement of the cutter 8. In the initial state, the cutter 8 conflicts with the first limit sensor 7. During operation, the cutting drive 4 drives the cutting telescopic rod 41 to extend while the cutting telescopic rod 41 drives the push plate 9 and the cutter 8 to move toward the second limit sensor 22. The cutter 8 cuts the apical bud of the pineapple during the movement and completes the work of picking the apical bud of the pineapple. When it moves to the point of conflict with the second limit sensor 22, the controller 2 controls the cutting drive 4 to retract the cutting telescopic rod 41 in the reverse direction, and the cutter 8 moves in the reverse direction. When it moves to the point of conflict with the first limit sensor 7, the controller controls the cutting drive 4 to suspend operation.

[0036] In order to facilitate the conveying of the pineapple terminal buds removed from the cutter, a discharge chute 20 is provided. Figure 1 As shown, the discharge chute 20 is obliquely mounted on the support frame 21 near the blocking drive member 25. The pineapple terminal buds obtained by cutting are discharged into the discharge chute, and the discharge chute then guides the pineapple terminal buds outward for collection.

[0037] In order to prevent the push plate from approaching the cut pineapple apical bud, a limit baffle 6 is additionally installed. Figure 1 As shown, the stopper 6 is mounted on the cutter 8 and positioned between the trapezoidal blade 81 and the push plate 9. When the cutter rapidly cuts the pineapple terminal bud, the terminal bud remains in place due to inertia. The push plate, propelled forward by the telescopic cutting rod, moves closer to the terminal bud. The stopper 6 then pushes the terminal bud to follow the movement of the cutter 8.

[0038] In order to facilitate the installation of the second limit sensor 22, a sensor bracket 23 is additionally installed. Figure 1 As shown, the sensor bracket 23 is installed on the support frame 21 for supporting and installing the second limit sensor 22 .

[0039] In order to facilitate the installation of the cutting drive 4 and the first limit sensor 7, a support plate 5 is additionally installed. Figure 1 As shown, the support plate 5 is installed on the support frame 21 for supporting and installing the cutting drive 4 and the first limit sensor 7.

[0040] In order to facilitate the collection of pineapple fruits after cutting the terminal buds, a collection box 3 is additionally installed. Figure 1As shown, the collecting box 3 is installed close to the conveyor 1 and is used to receive the pineapples with the terminal buds removed and unloaded from the conveyor.

[0041] The cutting drive member 4 and the blocking drive member 25 can be pneumatic cylinders or hydraulic cylinders.

[0042] Working mode of this utility model:

[0043] The pineapples with terminal buds to be picked are aligned and placed on the conveyor belt 18 in a straight line at intervals. The controller 2 controls the drive motor 13 to start, and the drive motor 13 drives the conveyor shaft 16 to rotate. The output shaft 16 drives the driving wheel 15 to rotate, and the driving wheel 15 drives the driven wheel 12 to rotate. The driven wheel 12 drives the active roller 19 to rotate, and the active roller 19 drives the conveyor belt 18 and the driven roller 17 to rotate. The conveyor belt 18 drives the pineapples to be transported to the visual sensor 26. When the pineapples move to the bottom of the visual sensor 26 and are sensed by the visual sensor 26, the visual sensor sends data information to the controller. The controller receives the data information and controls the drive motor 13 to stop working and start the cutting drive 4. The cutting drive 4 drives the cutting telescopic rod 41 to extend. At the same time, the push plate 9 and the cutter 8 are driven to move. When the cutter 8 touches the pineapple, the auxiliary baffle 24 blocks the pineapple from moving in the same direction as the cutter. The cutter 8 cuts the pineapple terminal bud, and the top surface of the cutter 8 supports the pineapple terminal bud to follow the movement. When the cutter touches the second limit sensor 22, the controller 2 controls the cutting drive 4 to reversely drive the cutting telescopic rod to retract. While the cutting telescopic rod 41 drives the push plate and the cutter to move in the opposite direction, the controller 2 controls the blocking drive 25 to start. The blocking drive 25 drives the blocking telescopic rod 251 to extend. The blocking telescopic rod 251 is inserted between the pineapple terminal bud and the push plate 8, blocking the pineapple terminal bud from moving in the opposite direction with the cutter, so that the pineapple terminal bud separates from the cutter and falls into the discharge chute 20 below. The discharge chute guides the pineapple terminal bud outward for collection. When the cutter 8 moves in the opposite direction and contacts the first limit sensor 7, the controller 2 temporarily stops the cutting actuator 4, retracts the blocking actuator 25 with the blocking telescopic rod 251, and activates the drive motor 13. The conveyor belt 18 then transports the next pineapple toward the visual sensor 26. The conveyor belt then unloads the harvested pineapple fruit into a collection bin. This cycle repeats to continuously harvest the terminal buds of pineapples.

[0044] It should be noted that when the cutter contacts the second limit sensor, the controller can control the cutting drive to delay for 2 to 3 seconds before driving the cutting telescopic rod to retract in the opposite direction. This provides sufficient time for the blocking drive to drive the blocking telescopic rod to insert between the pineapple terminal bud and the push plate.

[0045] The above embodiments are preferred implementation methods of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. These modifications still fall within the scope of the technical features of the present invention.
