TECHNICAL FIELD

[0001] The application belongs to the technical field of water bamboo harvesting, and particularly relates to an automatic water bamboo harvesting device. BACKGROUND

[0002] Water bamboo is a kind of aquatic vegetable, which is a perennial root grass plant of the genus Zizania in the family Poaceae. The whole plant can grow to about 1-2 meters. The stems of water bamboo are divided into aboveground stems and underground stems. The aboveground stems are short and some of them are buried in the soil. At present, the harvesting of water bamboo is mainly carried out by manual use of sickles. In some areas, semi-automatic harvesting equipment is used in combination with manual work. The patent with the publication number CN115053694A discloses a water bamboo harvester. The water bamboo harvester comprises a vehicle frame, a machine frame arranged on the vehicle frame, a root cutting mechanism, a clamping and conveying mechanism, an alignment mechanism and a water bamboo separating mechanism. The clamping and conveying mechanism comprises two groups of conveying assemblies arranged gradually upward and inclined from front to back and synchronously driven. The conveying assemblies form a conveying channel for clamping and conveying water bamboo stems and leaves between them. The alignment mechanism comprises a guide assembly arranged horizontally along the front and rear directions and located below the middle part of the conveying channel. The guide assembly is provided with an alignment channel with a smaller spacing than the diameter of the top of the water bamboo. The water bamboo separating mechanism is arranged at the output end of the alignment channel and is used to cut off the water bamboo stems and leaves at the upper surface of the output end of the alignment channel. The clamping and conveying mechanism of the existing water bamboo harvester has a single function and cannot reliably and orderly convey the water bamboo. Because the leaves of water bamboo are often long, the water bamboo is prone to falling during transportation to a high place. The roots and stems of the water bamboo are prone to bending between the roots and stems and the leaves, which causes damage to the roots and stems of the water bamboo and affects the harvesting effect. At the same time, the existing water bamboo harvester uniformly conveys the harvested water bamboo to a single collection box. The water bamboo is prone to stacking between each other, and the water bamboo at the bottom is prone to being squeezed. Secondly, the water bamboo needs to be manually unloaded and packed due to the unified collection, which greatly increases the recovery and packaging cost. Therefore, it is necessary to design an automatic water bamboo harvesting device to overcome the above difficulties. SUMMARY

[0015] Before harvesting water chestnuts, the operator stacks several first material frames vertically within the packing trough. Initially, both the second and third baffles are extended, with the second baffle at the bottom of the lowest first material frame and the third baffle inside the slot of the first material frame. By setting the second and third baffles, the first material frames fall sequentially. Then, the second baffle retracts, and the lowest first material frame slides along the limiting plate onto the slider. Due to the limiting plate and the inner wall of the storage channel, the first material frame falls precisely onto the slider. Then, the second positioning cylinder on the slider extends, and its piston shaft inserts into the second through hole, thus fixing the first material frame to the slider. Next, the first motor drives the slider to move downwards towards the first discharge port. When the transmitting sensor faces the second receiver, the second receiver... The device sends an electrical signal to the control component, which then stops the first motor. The water chestnuts then fall from the first discharge port into the first material box along the feeding frame. At this point, the weighing sensor detects the total weight of the first material box. When the total weight of the first material box reaches the initial preset value, the control component sends an electrical signal to the first motor and the temporary storage component. The first motor drives the first material box to move along the support steps into the storage channel. When the first material box is in place, the piston shaft of the first positioning cylinder extends into the first through hole, thus fixing the first material box. When the first material box detaches from the first discharge port, the first cylinder on the temporary storage component operates, controlling the first baffle to extend, allowing the water chestnuts to be temporarily stored in the storage box. At this point, the operator can manually remove any defective water chestnuts from the conveyor belt assembly. Then, the second positioning cylinder on the slider retracts, and the slider returns to its initial position in the storage channel. When the transmitting sensor faces the first receiver, the first motor stops rotating and the slider is in its initial position. Then, the second baffle retracts once, and a new first material box falls onto the slider. Then, the third baffle retracts once, and the remaining first material boxes descend onto the second baffle. Then, the slider moves the new first material boxes back below the first discharge port. Then, the first cylinder of the temporary storage component operates, controlling the storage boxes to reopen, thus continuously packing the water chestnuts. After the water chestnuts are harvested, the slider moves to the bottom of the first material boxes and then transports each first material box sequentially to the end of the storage channel, so that the operator can remove the first material boxes from the storage channel through the gripping openings on the first material boxes.

[0016] Preferably, the conveyor belt assembly includes a mounting bracket, a conveyor belt body, and a drive motor; the conveyor belt body is rotatably connected to the mounting bracket, and the drive motor is disposed on the side of the mounting bracket; when the drive motor is working, it drives the conveyor belt body to rotate relative to the mounting bracket; the conveyor belt body is provided with a plurality of evenly distributed partition plates.

[0029] Before harvesting water chestnuts, the operator stacks several first material frames 92 vertically within the packing slot 91. Initially, both the second baffle 917 and the third baffle 922 are extended, with the second baffle 917 positioned at the bottom of the lowest first material frame 92 and the third baffle 922 within the slot 919 of the first material frame 92. By setting the second baffle 917 and the third baffle 922, the first material frames 92 are made to fall sequentially. Then, the second baffle 917 retracts, and the lowest first material frame 92... The material frame 92 slides along the limiting plate 920 onto the slider 94; due to the limiting plate 920 and the inner wall of the storage channel 93, the first material frame 92 falls precisely onto the slider 94; then the second positioning cylinder 913 on the slider 94 extends, and the piston shaft of the second positioning cylinder 913 is inserted into the second through hole 918, so that the first material frame 92 and the slider 94 can be fixed; then the first motor 96 drives the slider 94 to move downward toward the first discharge port 14, and the transmitting sensor 98 moves toward the second receiver. At time 99, the second receiver 99 sends an electrical signal to the control component 7, which then stops the first motor 96. The water chestnuts then fall along the pouring frame 10 from the first discharge port 14 into the first material frame 92. At this time, the weighing sensor 914 detects the total weight of the first material frame 92. When the total weight of the first material frame 92 reaches the initial preset value, the control component 7 sends electrical signals to the first motor 96 and the temporary storage component 13. The first motor 96 then moves the first material frame 92, and the first material frame 92... 2 will move along the support step 910 into the storage channel 93; when the first material frame 92 is placed in place, the piston shaft of the first positioning cylinder 911 extends out and into the first through hole 912, so that the first material frame 92 is fixed; when the first material frame 92 is removed from the first discharge port 14, the first cylinder 133 on the temporary storage assembly works to control the first baffle 132 to extend, so that the water chestnut can be temporarily stored in the storage frame 131; at this time, the operator can manually pick out the unqualified water chestnuts on the conveyor belt assembly 8. Then the second positioning cylinder 913 on the slider 94 retracts first, and then the slider 94 returns to the initial position of the storage channel 93; when the transmitting sensor 98 is facing the first receiver 97, the first motor 96 stops rotating and the slider 94 is in the initial position; then the second baffle 917 retracts once, and the new first material box 92 will fall onto the slider 94; then the third baffle 922 retracts once, and the remaining first material box 92 will fall onto the second baffle 917 as a whole; then the slider 94 drives the new first material box 92 to be placed below the first discharge port 14 again, and then the first cylinder 133 of the temporary storage component 13 works to control the storage box 131 to reopen, so that the water chestnuts can be continuously packed.After the water chestnut harvest is complete, the slider 94 moves to the bottom of the first material box 92; then the second positioning cylinder 913 extends, thereby transporting each first material box 92 sequentially to the end of the storage channel 93. The operator can then retrieve the first material box 92 from the storage channel 93 through the gripping opening 923 on the first material box 92. By setting up the separator 84, the water chestnuts can be placed sequentially on the conveyor belt body 82, preventing them from piling up on the conveyor belt body 82 and improving the overall conveying efficiency.

[0030] Example 2 like Figure 14 As shown, the packing method in this embodiment differs from that in Embodiment 1; Embodiment 1 allows for weighing and packing of water chestnuts; this embodiment is suitable for rapid packing of water chestnuts, eliminating the need to transport them to the bottom of the main frame 1 via the unloading frame 10, and packing can be performed directly above the main frame 1. A feeding frame 18 is provided between the conveyor belt assembly 8 and the unloading frame 10, and a second feeding port 19 is provided on the slope of the feeding frame 18; a second material frame 20 is provided directly below the feeding frame 18, and a pushing cylinder 21 is provided on the side of the feeding frame 18, with a push plate 22 on the piston shaft of the pushing cylinder 21.

[0031] When water chestnuts need to be quickly packed, there is no need to weigh them. Since the temporary storage component 13 is detachable from the main frame 1, the temporary storage component 13 is replaced with the unloading frame 18, and a second material box 20 is set below the unloading frame 18. The legs of the unloading frame 18 limit the side of the second material box 20. When the second material box 20 is packed, it is pushed out by the pusher cylinder 21. Then, a new second material box 20 is placed below the unloading frame 18, so that packing can continue.
