Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a double-roller finger-type chili harvesting device. Background Technology

[0002] In large-scale chili pepper cultivation, mechanized harvesting is key to improving efficiency. Depending on factors such as chili pepper variety, plant height, and planting density, different mechanized harvesting equipment is required. Existing chili pepper harvesting devices can be categorized into comb-type chili pepper harvesters, vibrating chili pepper harvesters, and mechanical clamping chili pepper harvesters based on the different harvesting principles of their picking components.

[0003] For example, a comb-type chili harvester uses a brush-type picking component that contacts the chili plant at a specific speed and angle. The comb teeth or brush penetrate the plant, brushing the chilies off the stems. When the harvester's brush speed reaches 100-150 revolutions per minute, it can effectively pick most of the mature chilies. Another example is a vibrating chili harvester, which uses a vibration device to generate vibrations of a specific frequency and amplitude that are transmitted to the chili plant. When the vibration frequency is between 30-50 Hz and the amplitude is about 3-5 cm, the chilies detach from the stems due to inertia.

[0004] However, both of the aforementioned harvesters have drawbacks in mechanized chili harvesting under row-and-column planting patterns. In row-and-column planting, chili plants are arranged in rows with relatively fixed row and plant spacing, typically 60-80 cm between rows and 15-40 cm between plants. With the high-speed rotation or movement of the comb-type harvester's teeth or brushes, the need to pass through the plant to pick the chilies can easily cause stems and branches to break or tear. Vibratory harvesters use vibration to detach the chilies from the stem. In row-and-column planting, the close arrangement of plants can lead to excessively strong vibrations, causing chilies to collide and be crushed. Furthermore, the spacing between adjacent plants and the extent of shading in row-and-column planting can affect the vibration transmission, preventing some chilies from falling off smoothly. Summary of the Invention

[0005] The purpose of this invention is to provide a harvesting device for the chili pepper harvesting process in various row-and-column patterns, so as to reduce damage to the plants and improve harvesting efficiency.

[0006] To achieve the above objectives, the present invention adopts the following solution:

[0007] A double-roller snap-finger type chili harvesting device includes a frame for connecting a walking device, a spiral roller assembly, and a conveying mechanism;

[0008] A pair of spiral roller assemblies are arranged in parallel on the frame, and a harvesting channel for harvesting chili peppers is provided between the pair of spiral roller assemblies. The harvesting channel is arranged along the traveling direction of the traveling equipment, and the spiral roller assemblies on both sides of the harvesting channel rotate in opposite directions.

[0009] The spiral roller assembly includes a roller shaft, rubber springs, and a power unit for driving the roller shaft to rotate. The roller shaft and the power unit are both mounted on the frame. The roller shaft is connected to the output end of the power unit, and the rubber springs are connected to the side wall of the roller shaft. Multiple rubber springs are arranged in a linear array along the axial direction of the roller shaft to form a harvesting unit for picking up peppers from the plant in the harvesting channel.

[0010] The conveying mechanism is located below the harvesting channel, and the conveying mechanism is provided with a conveying surface for receiving chili peppers.

[0011] In row-and-column planting mode, the harvesting channels of this roller-fingered chili harvesting device are arranged along the direction of travel of the walking equipment, adapting to the direction of the planting rows. A pair of spiral roller assemblies are arranged in parallel and rotate in opposite directions, which can effectively pick up and harvest the chilies on the plants, improving harvesting efficiency. Furthermore, the harvesting units are formed by the linear array of rubber springs on the roller shaft. Driven by the power unit, the roller shaft rotates, and the rubber springs can pick up the chilies over a large area in a regular manner. The rubber material has a certain degree of elasticity, which can cushion the impact on the chilies when in contact with them, reducing the impact force on the chilies during harvesting, thereby reducing damage to the chilies and better ensuring their quality.

[0012] Preferably, the harvesting channel is laid at an angle to the ground, with the entrance end of the harvesting channel lower than the exit end.

[0013] As a preferred option, a harvester is installed at the entrance of the harvesting channel, and the harvester is connected to the machine frame.

[0014] Preferably, a protective cover is provided on the outside of the roller shaft, which is positioned above the harvesting channel and has slots for the rubber spring to pass through.

[0015] Preferably, the conveying mechanism is a conveyor belt, which is installed below the harvesting channel and connected to the frame via a support.

[0016] Preferably, a collection box is provided at the output end of the conveyor belt.

[0017] Preferably, multiple harvesting units are arranged in a circle along the axis of the roller.

[0018] Preferably, the rubber springs located on both sides of the harvesting channel are arranged in an alternating pattern.

[0019] Compared with existing technologies, the present invention provides a double-roller spring-type chili harvesting device with the following substantial features and advancements: This double-roller spring-type chili harvesting device utilizes a harvesting channel formed by a pair of parallel spiral roller assemblies. The harvesting channel is arranged along the travel direction of the traveling equipment, adapting to the planting row direction in a row-and-column planting mode. This facilitates the smooth entry of chili plants into the harvesting channel. Driven by a power unit, the pair of rollers rotate in opposite directions on both sides of the harvesting channel, driving rubber springs to pick up the chilies from the plants, reducing the impact force on the chilies during harvesting, thereby minimizing damage and better ensuring the quality of the chilies. A conveying mechanism is located below the harvesting channel to collect and transport the harvested chilies, facilitating centralized processing and subsequent processing, improving the orderliness and convenience of the entire harvesting process. Furthermore, for chili planting situations with different row and plant spacing in a row-and-column planting mode, the travel route and speed of the traveling equipment can be adjusted to ensure the harvesting channel of the spiral roller assembly accurately aligns with the chili plant rows. The design of its double-roller structure and harvesting channel allows the device to adapt well to different planting specifications, exhibiting greater versatility. Attached Figure Description

[0026] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-5As shown in the present invention, a double-roller finger-type chili harvesting device is proposed in this embodiment, which aims to reduce damage to the plants and improve harvesting efficiency during the chili harvesting process in various row and column patterns.

[0028] This embodiment of the invention proposes a double-roller spring-type chili harvesting device. A harvesting channel is formed by a pair of parallel spiral roller assemblies, and this channel is positioned along the travel direction of the traveling device, adapting to the planting row direction in a row-and-column planting pattern. This facilitates the smooth entry of chili plants into the harvesting channel. Driven by a power unit, the pair of rollers rotate in opposite directions on both sides of the harvesting channel, causing rubber springs to pry and harvest the chilies from the plants. The harvesting units, formed by the linear array of rubber springs on the rollers, can pry the chilies over a large area in a regular manner, reducing the impact force on the chilies during harvesting, thereby reducing damage to the chilies and the plants, and improving harvesting efficiency.

[0029] like Figure 1 Combination Figure 2 As shown, a double-roller snap-type chili harvester includes a frame 1 for connecting a traveling device, a spiral roller assembly 2, and a conveying mechanism 3. A pair of spiral roller assemblies 2 are arranged parallel to each other on the frame 1. A harvesting channel 4 for harvesting chilies is provided between the pair of spiral roller assemblies 2. The harvesting channel 4 is arranged along the traveling direction of the traveling device. The spiral roller assemblies 2 located on both sides of the harvesting channel 4 rotate in opposite directions. The traveling device is not shown in the figure; a tractor can be used. For example, a tractor is connected to the frame 1 via a traction frame, thereby driving the double-roller snap-type chili harvester to perform harvesting operations in the field.

[0030] like Figure 2 Combination Figure 5 As shown, the spiral roller assembly 2 includes a roller shaft 21, rubber springs 23, and a power unit 22 for driving the roller shaft 21 to rotate. Both the roller shaft 21 and the power unit 22 are mounted on the frame 1. The roller shaft 21 is connected to the output end of the power unit 22. The rubber springs 23 are connected to the side wall of the roller shaft 21. Multiple rubber springs 23 are arranged in a linear array along the axial direction of the roller shaft 21, forming a harvesting unit for picking peppers from the plant within the harvesting channel 4.

[0031] like Figure 2 As shown, the conveying mechanism 3 is located below the harvesting channel 4. The conveying mechanism 3 is equipped with a conveying surface for receiving chili peppers. The conveying mechanism 3 is used to collect and transport harvested chili peppers, which is beneficial for centralized processing and subsequent processing of the chili peppers.

[0032] like Figure 3 As shown, a protective cover 24 is provided on the outer side of the roller 21. The protective cover 24 is positioned above the harvesting channel 4. The protective cover 24 has slots 25 for the rubber spring 23 to pass through.

[0033] During field operations, on the one hand, the protective cover 24 can, to a certain extent, prevent foreign objects such as weeds and stones from entering the harvesting channel 4 from above and contacting the roller 21, reducing the risk of equipment failure and ensuring the smooth progress of chili harvesting. On the other hand, the protective cover 24, installed above the harvesting channel 4, can guide the chilies that are flicked off by the rubber spring 23. After the chilies are separated from the plant, they will fall more accurately to the conveying mechanism 3 below under the restriction of the protective cover 24, reducing the situation of chilies scattering to the surroundings and improving the efficiency and integrity of chili collection.

[0034] For example, such as Figure 3 As shown, a pair of protective covers 24 are arranged in a V-shape on both sides of the harvesting channel 4, which helps to better guide the peppers that have detached from the plant.

[0035] like Figure 4 As shown, harvesting channel 4 is inclined to the ground, with its entrance lower than its exit. In this row-and-column planting pattern, the lower entrance of the inclined harvesting channel 4 facilitates harvesting the chili peppers from a lower position using the rubber spring 23. For chili peppers distributed at different heights on the plant, this inclined design allows for a more reasonable harvesting angle, ensuring that chili peppers from the bottom to the top of the plant are harvested more smoothly, thus improving the overall harvesting quality. For example, the angle of inclination of harvesting channel 4 to the ground is 30 degrees. o -45 o .

[0036] According to some preferred embodiments of the present invention, such as Figure 4 As shown, a plant lifter 5 is installed at the entrance of the harvesting channel 4. The plant lifter 5 is connected to the frame 1. The plant lifter 5 is used to guide the plants to the standard position at the entrance of the harvesting channel 4, making the distribution of peppers within the harvesting channel 4 more regular. This helps improve the accuracy of the rubber snapper 23 in striking the peppers.

[0037] In addition, during the harvesting process, the plant straightener 5 first straightens and guides the plant, avoiding excessive squeezing or damage to the stems caused by the spiral roller assembly 2 forcibly acting on the tilted plant when picking the peppers, thus helping to protect the overall integrity of the plant.

[0038] like Figure 4 As shown, the conveying mechanism 3 is a conveyor belt 31, which is positioned below the harvesting channel 4 and connected to the frame 1 via a bracket 32. For row-and-column chili planting patterns with different row and plant spacings, the position of the conveyor belt 31 relative to the harvesting channel 4 can be changed by adjusting the connection position of the bracket 32 ​​on the frame 1, so as to better match the harvesting path of chilies under various planting specifications.

[0039] Among them, such as Figure 4 As shown, a collection box 6 is provided at the output end of the conveyor belt 31. The collection box 6 effectively prevents the chili peppers from scattering into the field after being output from the conveyor belt 31, avoiding potential loss, soil contamination, or mixing with field debris due to the chili peppers falling to the ground. This helps ensure the integrity of the chili pepper harvest while maintaining the cleanliness of the chili peppers and reducing the workload of subsequent cleaning.

[0040] like Figure 3 As shown, the rubber springs 23 located on both sides of the harvesting channel 4 are arranged in a staggered pattern. In this way, the staggered arrangement of the rubber springs 23 can more comprehensively cover the plant space within the harvesting channel 4. The rubber springs 23 on both sides work together to reduce blind spots in the harvesting of peppers on the plants. Whether the peppers are located on the outer, inner, or middle part of the plant, they can be touched and knocked off by the rubber springs 23, thereby significantly improving the pepper harvesting rate.

[0041] To further improve the stability of the spiral roller assembly 2, multiple harvesting units are arranged in a circular pattern along the axis of the roller shaft 21. For example, as... Figure 5 As shown, the two sets of harvesting units are arranged in a circle along the axis of roller 21. The number of harvesting units can be selected according to the actual harvesting situation, preferably 2-5 sets.

[0042] During the harvesting process, the circularly arranged harvesting units can continuously and stably harvest chilies. Due to their all-around coverage and uniform pressure distribution, they can ensure that the harvesting efficiency remains at a high level under different rotation speeds and harvesting conditions. They can also effectively reduce equipment vibration and jamming caused by uneven or unstable harvesting, extend the service life of the equipment, and ensure the smooth progress of chili harvesting.

[0043] In this embodiment of the invention, a double-roller finger-type chili harvesting device is used by connecting the frame 1 to a suitable walking device, ensuring a firm and stable connection to prepare for subsequent field operations. The walking device is then started, allowing the harvesting device to move slowly along the chili planting rows. The walking speed is adjusted reasonably according to factors such as the density and growth status of the chili plants and the harvesting capacity of the device to ensure efficient and high-quality chili harvesting.

[0044] As the harvesting device moves forward, the lifting device 5 first contacts the chili plants, straightening any plants that may be lying down, tilting, or growing haphazardly, and guiding them toward the entrance of the harvesting channel 4.

[0045] Once the chili pepper plants enter the harvesting channel 4, the power unit 22 of the spiral roller assembly 2 is activated, causing the roller shaft 21 to begin rotating. The rubber springs 23, located on both sides of the harvesting channel 4 and arranged in a staggered pattern, with multiple harvesting units arranged in a circular pattern along the axis of the roller shaft 21, begin to pick up the chili peppers from the plants as the roller shaft 21 rotates.

[0046] As the rubber spring 23 rotates, it applies force to the chili peppers from different directions using its elasticity, causing the peppers to fall from the plant. Because the harvesting channel 4 is inclined to the ground, with the inlet end lower than the outlet end, the fallen peppers roll or slide towards the outlet of the harvesting channel 4 under the influence of gravity. The peppers fall from the outlet of the harvesting channel 4 onto the conveyor belt 31 below. The conveyor belt 31 continues to operate under the stable support of the bracket 32 ​​and the frame 1, smoothly transporting the peppers to the output end.

[0047] At the output end of conveyor belt 31, the chilies are fed into collection box 6. As the harvesting device continues to move forward, the chilies are continuously harvested, conveyed, and collected until the chili harvesting operation for the entire planting area is completed.

[0048] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
