[0017] The hopper is trapezoidal in shape, with a larger upper end and a smaller lower end.

[0018] A sorting method of an intelligent bamboo strip automatic sorting device comprises the following steps:

[0019] S1. Placement and initial movement of bamboo strips:

[0020] The cut bamboo strips are placed in the hopper. Under the action of gravity, the bamboo strips move between the two sets of support plates, and the lowest bamboo strips fall onto the conveyor belt.

[0021] S2. Bamboo strip transportation and cleaning:

[0022] The first motor is started to drive the conveyor belt to convey the bamboo strips, and the convex parts of the bamboo nodes are cleaned by the cutter until the bamboo strips are conveyed to the two groups of sorting racks.

[0023] S3, bamboo strip finishing:

[0024] The second motor is started to drive the wedge block to move up and down in the hopper to arrange the bamboo strips in the hopper.

[0025] S4. Sorting of large bamboo strips:

[0026] The first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver are started. When the first infrared receiver does not receive a signal or the second infrared receiver does not detect a signal, it is determined that the bamboo strips are large, the outer electromagnetic clutch is started, and the second motor drives one side of the sorting frame to flip over and sort the small bamboo strips to one side of the support table.

[0027] S5. Sorting of small bamboo strips:

[0028] When the first infrared receiver or the second infrared receiver receives a signal, it determines that the bamboo strips are small, starts the electromagnetic clutch on the other side, and the second motor drives the sorting frame on the other side to flip, and sorts the large bamboo strips to the other side of the support platform.

[0029] In the present application, first, the cut bamboo strips are placed in a hopper, and the bamboo strips move downward between two sets of support plates under their own gravity, while the bamboo strips at the bottom fall onto a conveyor belt;

[0030] Then, the first motor is started to drive the conveying roller to rotate, and the rotation of the conveying roller can drive the conveyor belt to operate, and the movement of the conveyor belt can convey the bamboo strips. When one end of the bamboo strip hits the two resistance plates, the bamboo strip will not move with the conveyor belt, and the conveyor belt continues to move, which can drive the block to hit the other end of the bamboo strip and continue to convey. The bamboo strip can be driven to move by the block, and the bamboo joint convex parts of the bamboo strip will be cleaned by the cutters on both sides during the movement, until the bamboo strips are conveyed to the two groups of sorting racks;

[0031] At the same time, the second motor is started to drive the transmission rod to rotate, and the rotation of the transmission rod can drive the eccentric disk to rotate. During the rotation of the eccentric disk, the extension rod can be driven to move up and down through the annular groove and the sliding column, which can drive the lifting bar to move. The movement of the lifting bar can drive the fixed bars on both sides to move up and down. When the fixed bar moves upward, it can drive the wedge block to move upward, which can drive the bamboo bar to move upward. When the fixed bar moves downward, it can drive the wedge block to move downward. The downward movement of the wedge block can drive the wedge block to slide on one side of the fixed bar through the bamboo bar below and compress the first spring. When the wedge block moves to the bottom of the bamboo bar, it will reset and move under the action of the first spring, so that the wedge block can move up and down and reciprocate in the hopper, which can sort the bamboo bars in the hopper and make the bamboo bars flip to a suitable angle for falling;

[0032] Finally, the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver are started. When the first infrared receiver cannot receive the infrared rays emitted by the first infrared transmitter, or the second infrared receiver cannot detect the infrared rays of the second infrared transmitter, the bamboo strips are relatively large, and the outer electromagnetic clutch is started. At this time, the second motor rotates to drive the fixed strip to move up and down, which will drive the two connecting rods to move up and down. When the connecting rod moves upward, it can drive the rack to move upward through the second spring. The upward movement of the rack can drive the gear to rotate. The rotation of the gear can drive the input end of the electromagnetic clutch to rotate, and drive the rotating rod to rotate through the output end. The rotation of the rotating rod can drive the two sorting racks on one side to flip through the rotating bar, so that the small bamboo strips can be sorted to one side of the support platform;

[0033] When the first infrared receiver receives the infrared ray emitted by the first infrared transmitter, or the second infrared receiver receives the infrared ray emitted by the second infrared transmitter, the bamboo strips are small, and the electromagnetic clutch on the other side is started. At this time, the second motor rotates to drive the fixed strip to move up and down, which will drive the two connecting rods to move up and down. When the connecting rod moves upward, it can drive the rack to move upward through the second spring. The upward movement of the rack can drive the gear to rotate. The rotation of the gear can drive the input end of the electromagnetic clutch to rotate, and drive the rotating rod to rotate through the output end. The rotation of the rotating rod can drive the two sorting racks on one side to flip through the rotating bar, and sort the large bamboo to the other side of the support platform.

[0034] Beneficial effects: In the present invention, the intelligent automatic bamboo strip sorting device can not only limit the position of the bamboo strips through the setting of two groups of support plates, but also clean the bamboo joint protrusions of the bamboo strips through the cutter on one side of the support plate during the movement of the bamboo strips, so that the bamboo strips can move more smoothly and avoid the bamboo strips from sliding against each other during the movement.

[0035] In the present invention, the intelligent automatic bamboo strip sorting device can drive the wedge blocks on both sides to move up and down reciprocatingly in the hopper by starting the second motor. During the movement, the bamboo strips in the hopper can be sorted to avoid the bamboo strips from getting stuck in the hopper, thereby improving the efficiency of the free fall of the bamboo strips.

[0036] In the present invention, the intelligent automatic bamboo strip sorting device can drive the output end of the electromagnetic clutch to rotate during the lifting and reciprocating movement of the fixed bar by connecting the rack under the fixed bar, and can control the start and stop of the electromagnetic clutch according to the detection result, so that it is convenient to drive the rotation of the two groups of sorting racks respectively, so as to facilitate the sorting of bamboo strips of different sizes;

[0037] In the present invention, the intelligent automatic bamboo strip sorting device can measure the length and width of the bamboo strips respectively by arranging a first infrared transmitter, a first infrared receiver, a second infrared transmitter and a second infrared receiver on two support bars, without the need for additional measuring equipment for detection, and is more convenient to use;

[0038] In the present invention, by starting the first motor, the second motor and the electromagnetic clutch, the bamboo strips can be transported, and the start and stop of the electromagnetic clutch can be controlled according to the measurement results of the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver, so that it is convenient to sort bamboo strips of different sizes, and the bamboo node protrusions of the bamboo strips can be automatically cleaned during the transportation process, so that the transportation is smoother and the sorting efficiency is improved.

The two sets of mounting seats 8 are respectively provided with a first infrared transmitter 39, a first infrared receiver 40, a second infrared transmitter 41 and a second infrared receiver 42 which cooperate with each other, for detecting the size of the bamboo strips. By placing the bamboo strips in the hopper 3 and starting the sorting mechanism for sorting, the bamboo strips in the hopper 3 can be automatically moved downward and guided by the two sets of support plates 2 until the bamboo strips fall on the conveyor, and the conveyor is started for transportation. During the transportation process, the protrusions of the bamboo strips and bamboo nodes can be cleaned by the cutter 22, and the bamboo strips can be driven to move downward. The bamboo strips are moved to the two groups of sorting racks 9. At this time, the first infrared transmitter 39, the first infrared receiver 40, the second infrared transmitter 41 and the second infrared receiver 42 are started to judge the size of the bamboo strips, that is, the first infrared transmitter 39 and the first infrared receiver 40 detect the length of the bamboo strips, and the second infrared transmitter 41 and the second infrared receiver 42 detect the height of the bamboo strips. When the bamboo strips are small, the electromagnetic clutch 34 on one side is started, which can drive the two sorting racks 9 on one side to flip through the sorting mechanism and flip the bamboo strips to one side of the support platform 1. Conversely, the other electromagnetic clutch 34 is started to flip the large bamboo strips to the other side of the support platform 1.

[0063] The hopper 3 is trapezoidal, with a large upper end and a small lower end. By setting the hopper 3 to have a large upper end and a small lower end, it is convenient to automatically control the automatic falling of the bamboo strips.

[0064] A sorting method of an intelligent bamboo strip automatic sorting device comprises the following steps:

[0065] S1. First, the cut bamboo strips are placed in the hopper 3. The bamboo strips will move downwards between the two sets of support plates 2 under their own gravity, and the bamboo strips at the bottom will fall onto the conveyor belt 12.

[0066] S2, then, start the first motor 14 to drive the conveyor belt 12 to convey the bamboo strips, and the bamboo joint convex parts of the bamboo strips will be cleaned by the cutter 22 during the conveying process until the bamboo strips are conveyed to the two groups of sorting racks 9;

[0067] S3, simultaneously starting the second motor 20 to drive the wedge block 30 to move up and down in the hopper 3 to sort the bamboo strips in the hopper 3;

[0068] S4, finally start the first infrared transmitter 39, the first infrared receiver 40, the second infrared transmitter 41 and the second infrared receiver 42. When the first infrared receiver 40 cannot receive the infrared rays emitted by the first infrared transmitter 39, or the second infrared receiver 42 cannot detect the infrared rays of the second infrared transmitter 41, the bamboo strips are relatively large, and the outer electromagnetic clutch 34 is started. At this time, the second motor 20 rotates and drives the two sorting racks 9 on one side to flip, so that the small bamboo strips can be sorted to one side of the support platform 1.

[0069] S5. When the first infrared receiver 40 receives the infrared ray emitted by the first infrared transmitter 39, or the second infrared receiver 42 receives the infrared ray emitted by the second infrared transmitter 41, the bamboo strips are small, and the electromagnetic clutch 34 on the other side is started. At this time, the second motor 20 rotates and drives the two sorting racks 9 on the other side to flip, and sort the large bamboos to the other side of the support platform 1.

[0070] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 14, the second motor 20, the electromagnetic clutch 34, the first infrared transmitter 39, the first infrared receiver 40, the second infrared transmitter 41 and the second infrared receiver 42 are commonplace, and are conventional means or common knowledge, and will not be elaborated herein. Those skilled in the art may make any optional selections according to their needs or convenience.
