Abstract
Description
Technical Field
[0001] This utility model relates to the field of small agricultural machinery, specifically to a multifunctional small chili pepper harvesting device. Background Technology
[0002] Currently, chili pepper harvesting is mainly done manually, but this method is inefficient and wastes a lot of labor. Existing technology, patent number CN202321795801.2, discloses a red chili pepper harvesting robot, including a driving device, a horizontal moving device, a vertical moving device, a robotic arm device, and a gripping device. The two ends of the driving device, the horizontal moving device, the vertical moving device, the robotic arm device, and the gripping device are connected sequentially. This invention integrates the functions of identifying, gripping, and collecting red chili peppers. The camera on the gripping device scans and identifies the chili pepper trees on both sides of the robot under the movement of the horizontal and vertical moving devices. Then, the gripping device, under the extension of the robotic arm device, approaches the red chili pepper to a certain distance, grips the stem, and cuts off the top. Subsequently, under the combined action of the robotic arm device and the vertical moving device, the red chili pepper is placed into the collection basket in the middle of the driving device. This invention is multifunctional, environmentally friendly, and highly efficient, ensuring the timely harvesting of red chili peppers.
[0003] Although the technology achieves autonomous mobility, it is limited to vertical movement in the longitudinal and lateral directions, resulting in slightly poor flexibility. Furthermore, the robotic arm can only harvest a single crop and cannot cover a wide area, which means that despite its high speed, the efficiency remains low. While it can accurately harvest crops in experimental fields, it cannot benefit farmers' chili fields on a large scale. The intelligent systems, such as cameras and scanning recognition functions, further increase costs, reducing its practicality. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of current products, such as limited functionality, low efficiency, high harvesting losses, high cost, and excessive reliance on manual labor, and to provide a multifunctional small chili harvesting device.

[0028] A multi-functional mini chili harvesting device, such as Figure 1 As shown, the harvesting device includes a harvesting mechanism, a transport mechanism, a collection module, and a tillage device; the harvesting mechanism includes a rolling spiral cutter 2 and a branch gathering device 10; the transport mechanism includes a primary conveyor belt 1 and a secondary conveyor belt 3; the collection module includes a collection lifting box 5 and a crank-slider mechanism 8.
[0029] Furthermore, the rolling spiral cutters 2 are arranged in pairs side by side, and the number of primary conveyor belts 1 is set to three. The primary conveyor belts 1 and the rolling spiral cutters 2 are arranged alternately and crosswise, that is, each rolling spiral cutter 2 is provided with a primary conveyor belt 1 on both sides. Figure 2 As shown, the uniquely designed rotating spiral cutter uses a rotating drum and sharp blades to quickly and accurately cut peppers. Its principle primarily utilizes the combined action of the drum and spiral blades to achieve rapid cutting and transport of the crop. The drum holds the blades in place, maintaining structural stability in the cutting area, and guides the cut crop to the spiral blades for transport. The spiral blades use continuous rotation to separate the crop from the drum and propel it forward along the direction of the blades, ultimately delivering it to the designated location. The entire process relies on the coordinated work of the drum and spiral blades to achieve rapid cutting and transport of the crop. This harvesting method is not only fast but also reduces missed cuts and repeated cutting, thus significantly improving harvesting efficiency. In large-scale harvesting applications, the rotating spiral cutter can significantly shorten operation time, saving substantial labor and time costs for agricultural production.
[0030] Meanwhile, the rotating spiral cutter harvester is highly adaptable, capable of handling chili crops with varying growth conditions. By adjusting the drum's rotation speed and the cutter angle, it can accommodate chili crops of different heights and densities, achieving efficient harvesting. Furthermore, the rotating spiral cutter can adapt to different terrains and soil conditions, successfully completing harvesting tasks in both flat fields and mountainous terrain. Traditional harvesting methods often result in significant crop waste, while the rotating spiral cutter harvester significantly reduces this loss. Its precise cutting method and efficient harvesting speed maximize the preservation of crop integrity, minimizing damage and breakage during harvesting. This not only improves crop utilization but also brings higher economic benefits to farmers.
[0031] A rotating spiral cutter separates the chili peppers from their stems and leaves. The spiral cutter rotates continuously, working in conjunction with a stem-gathering device to collect the chili peppers. During collection, a primary conveyor belt operates, collecting the chili peppers and some stems and leaves cut by the spiral cutter and conveying them backward.
[0032] Furthermore, the initial portion of the secondary conveyor belt 3 is located below the end portion of the primary conveyor belt 1, and the number of secondary conveyor belts 3 is also set to three, corresponding one-to-one with the primary conveyor belt 1. Chili peppers and some stems and leaves are conveyed from the primary conveyor belt to the secondary conveyor belt, and then further conveyed to the collection lifting box. During this process, the separation of chili peppers and stems and leaves is simultaneously performed.
[0033] The specific structure of the primary conveyor belt is shown in the diagram below. Figure 3 As shown, the slope of the primary conveyor belt 1 is different from that of the secondary conveyor belt 3. The slope of the primary conveyor belt 1 is 37 degrees, and the slope of the secondary conveyor belt 3 is 15 degrees.
[0034] Furthermore, overflow baffles 4 are provided around the secondary conveyor belt 3 to prevent chili peppers from falling off the secondary conveyor belt.
[0035] Furthermore, a collection lifting box 5 for collecting chili peppers transported from the conveyor belt is provided below the end of the secondary conveyor belt 3.
[0036] like Figure 4 As shown, a crank-slider mechanism 8 is provided below the collecting lifting box 5. The crank-slider mechanism 8 is used to control the lifting and lowering of the collecting lifting box 5, so that the chilies in the collecting lifting box can slide into the collecting bag on the left side of the collecting lifting box, thus completing the collection of chilies. The separated chilies are conveyed to the collecting lifting box by a secondary conveyor belt; when the power sensor in the collecting lifting box detects that the weight in the collecting chamber has reached the critical point, it prompts to transfer the chilies, and the crank-slider mechanism starts to work to transfer the chilies.
[0037] To prevent excessive accumulation of chili peppers on the collection lifting box, a pneumatic device was designed to tilt the box at a fixed frequency. A pneumatic motor generates rotational motion, and when connected to a universal joint, it tilts the box. By adjusting the parameters of the pneumatic components, the box can be tilted smoothly and regularly at a fixed frequency, transporting all the chili peppers to the collection bag next to the harvesting vehicle, thus completing the collection task. During the collection process, an eccentric motor simultaneously vibrates and drives a screening mechanism, enabling both transportation and screening to be performed concurrently.
[0038] Furthermore, the branch-gathering device 10 is located at the front of the harvesting device and is used to gather irregularly growing peppers for easier harvesting. The control module controls the track drive motor, and the camera observes the planting area, moving the branch-gathering device to a designated position on the corresponding pepper ridge.
[0039] Furthermore, such as Figure 4 As shown, the tillage device includes a drive worm gear 6, a tillage mechanism 7, and a stem-rotating cutting blade 9;
[0040] The branch and stem rotary cutting blade 9 is located below the rolling spiral cutting blade 2 and is used to rotary cut the branches and stems of the chili pepper tree after harvesting.
[0041] The drive worm 6 and tillage mechanism 7 are located at the tail of the harvesting device. The drive worm 6 controls the up-and-down movement of the tillage mechanism 7, which, driven by power, can renovate the soil around the chili peppers. The drive worm is adjusted according to the depth of the chili pepper roots so that it can just remove the roots, and the rotary tillage mechanism is used to till the soil.
[0042] The working principle of the multifunctional mini chili harvesting device of this invention is as follows:
[0043] Step 1: As the multi-functional small chili harvesting device moves forward, the branch gathering device 10 first contacts the chili stem, gathering the irregularly growing chilies together to facilitate further harvesting.
[0044] Step 2: The gathered chili branches enter the rolling spiral cutter 2. The four rolling spiral cutters are arranged in pairs and rotate outward. When the chili branches enter, the slow-rotating blades will squeeze the chili off the chili branches.
[0045] Step 3: While the harvested chili pepper plants are still standing in the ground, the rotating cutting blade 9 below the spiral cutting blade 2 spins at high speed, cutting off the branches of the chili pepper plants and causing them to fall to the ground.
[0046] Step 4: The squeezed peppers fall onto the three primary conveyor belts 1 on both sides of the rolling spiral cutter. The primary conveyor belts are relatively rough to increase friction and prevent the peppers from falling. The primary conveyor belts transport the peppers upwards.
[0047] Step 5: The chili peppers transported to the top by the first-level conveyor belt 1 fall onto the second-level conveyor belt 3 under the action of gravity. The initial part of the second-level conveyor belt 3 is located below the end of the first-level conveyor belt 1. There are also three second-level conveyor belts, which correspond one-to-one with the first-level conveyor belts. The difference is that the slope is different, and there are denser anti-overflow baffles 4 around the second-level conveyor belts.
[0048] Step 6: The chili peppers transported by the secondary conveyor belt 3 further reach the collection lifting box 5. The collection box is equipped with a timed lifting program. When the time comes, the crank slider mechanism 8 under the collection box starts to work, the collection box rises, and the chili peppers slide into the collection bag on the left side of the multi-functional small chili pepper picking device, thus completing the chili pepper collection work.
[0049] Step 7: After the chili harvesting and collection are completed, the tilling device at the rear of the multi-functional small chili harvesting device enters working mode. The two motors start to rotate. According to the depth of the chili roots, the drive worm 6 is adjusted so that it can just hoe off the chili roots. The tilling mechanism 7 begins to descend along the spiral rod. The chili roots after the branches have been cut are still buried in the soil. The tilling mechanism 7 digs them out and renovates the land.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
