Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a harvesting device for hard-grained fruits. Background Technology

[0002] Harvesting hard-fruited crops such as Sichuan pepper, goji berries, and hawthorn is a crucial part of agricultural production. Currently, harvesting these crops mainly relies on manual labor or simple handheld tools (such as hand-held shears). This involves manually picking or cutting the fruit stems, allowing the fruit to fall into suspended cloth bags or onto tarpaulins laid on the ground, and then collecting it afterwards. This method is extremely inefficient, with each person only able to harvest about 5 kilograms per hour. Furthermore, the repetitive manual labor is arduous, time-consuming, and costly, becoming an obstacle to increasing farmers' income and promoting industrial development.

[0003] To address the low efficiency of manual harvesting, some simple electric harvesting devices have been proposed. For example, patent application number CN201120560639.7 discloses a shoulder-mounted pepper harvester that uses a negative pressure fan driven by a power unit to generate suction, drawing the fruit off the branches. The fruit is then collected in an absorption tower via an absorption pipe.

[0004] The patented solution improves harvesting efficiency and reduces labor intensity to some extent. However, because the harvesting process relies solely on negative pressure for adsorption, it cannot distinguish between the fruit particles to be harvested and the adjacent new shoots, leaves, and small branches. During the adsorption process, the strong suction can easily suck in these tender tissues that should not be harvested or cause serious scratch damage. Since the new shoots are the foundation for next year's fruiting, their damage will directly lead to a decrease in the fruit setting rate next year, posing a technical problem that affects farmers' long-term income. Utility Model Content

[0005] To address the problem in the existing harvesting methods described in the background, which rely solely on negative pressure for adsorption during the harvesting process, making it impossible to distinguish between the fruit particles to be harvested and the adjacent new shoots, leaves, and small branches, the strong suction during fruit adsorption can easily suck in these tender tissues that should not be harvested or cause serious scratch damage. Since the new shoots are the foundation for next year's fruiting, damage to them will directly lead to a decrease in the fruit setting rate the following year, posing a technical problem that affects farmers' long-term income. This utility model provides a harvesting device for hard-particle fruits.

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

[0007] A device for harvesting hard-shelled fruits includes a main body and a suction head assembly. The main body houses a power module and a collection module. The power module is electrically connected to the collection module, and the suction head assembly is connected to the collection module. The suction head assembly includes:

[0008] A housing having an intake channel that extends through the housing and has an outlet that connects to the collection module;

[0009] An electrically driven shearing mechanism is disposed on the lower side of the suction channel and partially exposed at the entrance of the suction channel, for cutting off the fruit stalk;

[0010] A drive assembly is disposed inside the housing and electrically connected to the electrically driven scissor mechanism, and is located on the side of the suction channel.

[0011] Optionally, the electrically driven scissor mechanism includes a fixed blade, a movable blade, and a transmission component;

[0012] The fixed blade is fixedly disposed on the lower side of the inlet of the suction channel;

[0013] The movable blade is movably disposed below the fixed blade and overlaps the fixed blade portion vertically.

[0014] The cutting edges of the fixed blade and the movable blade are serrated, and the cutting edges of the movable blade and the fixed blade are staggered and can move relative to each other to form a shearing pair.

[0015] The transmission component is connected to the movable blade and the drive assembly, and is used to drive the movable blade to cut the fruit stem.

[0016] Optionally, the movable cutting edge is a rotating cutting edge;

[0017] A connecting shaft is provided at the center of the rotating blade;

[0018] The transmission component is a transmission belt, one end of which is connected to the drive assembly, and the other end is sleeved on the connecting shaft.

[0019] Optionally, the movable blade is a swing blade;

[0020] The transmission component is a crank-connecting rod, which connects the drive assembly and the oscillating blade.

[0021] Optionally, the drive assembly includes a power supply component and a drive motor, respectively disposed on both sides of the suction channel;

[0022] The power supply component is electrically connected to the drive motor;

[0023] The output shaft of the drive motor is connected to the transmission component.

[0024] Optionally, the suction head assembly further includes an inlet adjustment member, which is movably disposed on both sides of the inlet of the suction channel.

[0025] Optionally, the main body includes a box;

[0026] The power module includes a power supply component and a vacuum pump component disposed within the housing. The vacuum pump component is located above the power supply component, and the power supply component and the vacuum pump component are electrically connected.

[0027] The collection module includes a collection box and a connecting pipe. The collection box is disposed inside the box and is located on the side of the power supply component and the vacuum pump component. One end of the connecting pipe is connected to the collection box, and the other end is connected to the outlet of the suction channel.

[0028] The vacuum pump assembly is connected to the interior of the collection box.

[0029] Optionally, the collection box is provided with a discharge valve at the lower end, and the inner wall of the collection box has a flexible anti-collision layer.

[0030] Optionally, a rigid sleeve is provided on the portion of the connecting tube near the outlet of the suction channel.

[0031] Optionally, the lower side of the box is provided with a plurality of caster wheels, which are respectively located at the corners of the lower side of the box.

[0032] The beneficial effects of this utility model are:

[0033] This invention provides a harvesting device for hard-grained fruits. Instead of simply relying on airflow suction to forcibly tear the fruit off, it uses a drive component to activate an electrically driven shearing mechanism. This mechanism, with the portion of the shearing mechanism exposed at the entrance of the suction channel, actively cuts the fruit stalk. This "suction and shearing" process ensures that the fruit is cut off completely and quickly, and is immediately captured by the negative pressure airflow generated by the suction channel. The fruit is then rapidly transported into the collection module through an outlet connected to the collection module. This avoids the collateral damage to the newly sprouted buds, leaves, and small branches around the fruit caused by the strong and indiscriminate suction of traditional pure suction harvesters. It effectively protects the reproductive growth point of the fruit tree, ensuring the fruit set rate and long-term income for farmers in the following year.

[0034] Meanwhile, the layout of embedding the drive component inside the housing and placing it on the side of the suction channel greatly improves the integration and operational flexibility of the suction head assembly. Operators do not need to worry about external cables and can hold the suction head assembly freely and flexibly to work on fruits in different directions and heights, which greatly reduces labor intensity and achieves the dual goals of efficient harvesting and plant protection.

[0050] Harvesting hard-fruited crops such as Sichuan pepper, goji berries, and hawthorn is a crucial part of agricultural production. Currently, harvesting these crops mainly relies on manual labor or simple handheld tools (such as hand-held shears). This involves manually picking or cutting the fruit stems, allowing the fruit to fall into suspended cloth bags or onto tarpaulins laid on the ground, and then collecting it afterwards. This method is extremely inefficient, with each person only able to harvest about 5 kilograms per hour. Furthermore, the repetitive manual labor is arduous, time-consuming, and costly, becoming an obstacle to increasing farmers' income and promoting industrial development.

[0051] Some existing simple electric harvesting equipment, such as shoulder-mounted pepper harvesters, improve harvesting efficiency and reduce labor intensity to some extent. However, because their harvesting process relies solely on negative pressure adsorption, they cannot distinguish between the fruit to be harvested and the adjacent new shoots, leaves, and small branches. During the adsorption process, the strong suction can easily suck in these tender tissues that should not be harvested or cause serious scratch damage, thus affecting the fruit setting rate the following year. Therefore, existing electric harvesting equipment basically cannot meet the needs of farmers in production and cannot be widely accepted by the market. In current agricultural production, manual harvesting is still the main method, which is inefficient, costly, and difficult to manage, thus hindering the development of the agricultural industry and increasing farmers' income.

[0052] The hard-grained fruit picking device provided by this utility model integrates an electrically driven scissor mechanism into the suction head. It uses the suction airflow to draw the fruit stalk with the fruit into the inlet of the suction channel, and the electrically driven scissor mechanism actively cuts the fruit stalk, forming a "suction and scissor" effect. This ensures that the fruit is cut off completely and quickly, and is immediately captured by the negative pressure airflow generated by the suction channel. The fruit is then quickly transported into the collection module through the outlet connected to the collection module, thereby avoiding damage to the reproductive growth point of the fruit tree.

[0053] See Figures 1 to 2 The diagram shows a schematic of the hard-grained fruit picking device of the present invention, including a main body 1 and a suction head assembly 2. The main body 1 is provided with a power module 11 and a collection module 12. The power module 11 and the collection module 12 are electrically connected. The suction head assembly 2 is connected to the collection module. The suction head assembly 2 includes a housing 21. The housing 21 has a suction channel 22. The suction channel 22 passes through the housing 21, and the outlet of the suction channel 22 is connected to the collection module 12.

[0054] An electrically driven scissor mechanism 23 is located on the lower side of the suction channel 22 and is partially exposed at the entrance of the suction channel 22. It is used to cut the fruit stalk.

[0055] The drive assembly 24 is disposed inside the housing 21 and electrically connected to the electrically driven scissor mechanism 23, and is located on the side of the suction channel 22.

[0056] In this embodiment, the hard-grain fruit picking device does not simply rely on airflow suction to forcibly tear off the fruit. Instead, it uses airflow suction combined with manual adjustment by the user to draw the fruit stalk with the fruit close to the suction channel. Then, the electric-driven shear mechanism 23, driven by the drive component 24, actively cuts the fruit stalk at the entrance of the suction channel 22. The fruit is then sucked into the suction channel by the collection module 12. This "suction and shearing" process ensures that the fruit is cut off completely and quickly and is immediately captured by the negative pressure airflow generated by the suction channel 22. The fruit is then quickly transported into the collection module 12 through the outlet connected to the collection module 12. This avoids the collateral damage to the new buds, leaves, and small branches around the fruit caused by the strong and indistinguishable suction of traditional pure suction picking machines. It effectively protects the reproductive growth point of the fruit tree and ensures the fruit setting rate and long-term income for farmers in the following year.

[0057] Meanwhile, the layout of embedding the drive component 24 inside the housing 21 and placing it on the side of the suction channel 22 greatly improves the integration and operational flexibility of the suction head component 2. Operators do not need to worry about external cables and can hold the suction head component freely and flexibly to work on fruits in different directions and heights, which greatly reduces labor intensity and achieves the dual goals of efficient harvesting and plant protection.

[0058] Furthermore, the drive assembly 24 is built into the housing 21 and placed on the side of the suction channel 22. It can also be powered by an external cable to the drive assembly 24 and the electric drive scissor mechanism 23. This is a technical means well known to those skilled in the art, so it will not be described in detail here.

[0059] Specifically, when using the hard-particle fruit picking device of this utility model to pick small-particle (particle diameter less than 35mm) fruits, such as pepper and wolfberry, the picking efficiency can reach 25kg per hour, while also greatly reducing the user's physical exertion, which is of positive significance for the development of the agricultural industry.

[0060] Optionally, refer to Figure 2 and Figure 3 The electrically driven scissor mechanism 23 of this utility model includes a fixed blade 231, a movable blade 232, and a transmission component 233;

[0061] The fixed blade 231 is fixedly installed on the lower side of the inlet of the suction channel 22;

[0062] The movable blade 232 is movably disposed below the fixed blade 231 and partially overlaps the fixed blade 231 vertically.

[0063] The cutting edges of the fixed blade 231 and the movable blade 232 are serrated, and the cutting edges of the movable blade 232 and the fixed blade 231 are staggered and can move relative to each other to form a shearing pair.

[0064] The transmission component 233 is connected to the movable blade 232 and to the drive assembly 24, and is used to drive the movable blade 232 to cut the fruit stem.

[0065] In this embodiment, the fixed blade 231 is fixedly installed on the lower side of the suction channel inlet, providing a stable foundation and support for the shearing action. The movable blade 232 is movably installed and partially overlaps with the fixed blade 231, together forming a stable and reliable shearing pair. The transmission component 233 serves as the key hub for power transmission, transmitting the power output from the drive component 24 to the movable blade 232, driving it to move and achieve the shearing motion. This shearing mechanism, composed of the fixed blade 231, the movable blade 232, and the transmission component 233, has more controllable and precise mechanical action than pure suction. It can selectively shear tough fruit stalks while avoiding tender new buds. Its shearing action is clean and crisp, without tearing or shaking the branches, further reducing the risk of mechanical damage to the fruit trees.

[0066] Furthermore, both the fixed and movable blades are made of steel, with the steel of the fixed blade being harder than that of the movable blade.

[0067] Meanwhile, the blades of the fixed blade 231 and the movable blade 232 are specifically defined as serrated, and are arranged in an alternating manner and can move relative to each other to form a shearing pair. This design greatly enhances the shearing efficiency of the scissor mechanism. When facing hard granular fruits with tough stems, such as peppercorns and goji berries, the serrated blades can effectively increase friction and prevent the stems from slipping or shifting during the shearing process, ensuring a high success rate for the first cut. The shearing pair formed by the alternating blades is similar to the working principle of scissors, which can generate a continuous and uniform shearing force during the shearing process. This avoids the vibration damage to the fruit tree branches that may be caused by impact or collision cutting, making the harvesting process more stable, efficient, and plant-friendly.

[0068] Optionally, the movable blade 232 in this utility model is a rotating blade;

[0069] A connecting shaft 234 is provided at the center of the rotating blade;

[0070] The transmission component 233 is a transmission belt, one end of which is connected to the drive assembly 24, and the other end is sleeved on the connecting shaft 234.

[0071] In this embodiment, the rotating blade is driven by a transmission belt, which causes the rotating blade to rotate around the transmission shaft. This allows the shearing pair formed between the blade edge and the fixed blade to effectively cut the fruit stem. This structure is simple, reliable, and easy to maintain.

[0072] Furthermore, the drive belt can be replaced with a gear drive.

[0073] Optionally, the movable blade 232 in this utility model is a swing blade;

[0074] The transmission component 233 is a crank connecting rod, which connects the drive assembly 24 and the oscillating blade.

[0075] In this embodiment, the driving force output by the drive assembly 24 is converted into the power of the swing blade through the crank connecting rod, so that the swing blade reciprocates. The shearing pair formed between the blade edge and the fixed blade can effectively cut the fruit stem. In particular, the strip-shaped swing blade can make the electric drive scissor mechanism 23 have a larger contact area with the fruit stem, which makes it more adaptable in use and can cut the fruit stem. It is also easier to use.

[0076] Specifically, the oscillating blade has a strip-shaped saw blade structure.

[0077] Optionally, refer to Figure 4 The drive assembly 24 in this utility model includes a power supply component 241 and a drive motor 242, which are respectively disposed on both sides of the suction channel 22.

[0078] Power supply component 241 is electrically connected to drive motor 242;

[0079] The output shaft of the drive motor 242 is connected to the transmission component 233.

[0080] In this embodiment, the power supply component 241 and the drive motor 242 specifically included in the drive assembly 24 are respectively arranged on both sides of the suction channel 22. The power supply component 241 (such as a small lithium battery) provides an independent and stable power source for the drive motor 242, making the suction head assembly 2 a truly mobile independent working terminal. When the operator holds it to work, he is not restricted by cables at all, and the range of motion and working flexibility are greatly improved. The output shaft of the drive motor 242 is directly connected to the transmission belt, converting electrical energy into mechanical energy to drive the entire scissor mechanism.

[0081] The layout in this embodiment tightly integrates the power source and the actuator, reducing energy loss during transmission and improving the overall energy utilization efficiency and operational response speed of the device. Furthermore, the separate placement on both sides of the intake channel 22 ensures a more balanced weight distribution, facilitating user adjustments.

[0082] Furthermore, in this embodiment, the drive motor 242 has a power of 30 watts and a weight of approximately 500 grams.

[0083] Optionally, refer to Figure 5 The suction head assembly 2 of this utility model also includes an inlet adjustment component 25, which is movably disposed on both sides of the inlet of the suction channel 22.

[0084] In this embodiment, the inlet adjustment component 25 is movably disposed on both sides of the inlet of the suction channel 22, allowing the operator to manually adjust the effective inlet diameter according to the size and clustering of the target fruit. For single or sparsely clustered fruits, the diameter can be reduced to increase the speed and accuracy of the suction airflow; for clustered fruits, the diameter can be increased to improve the efficiency of a single harvest. This adjustable design greatly enhances the versatility of the device, enabling it not only to harvest Sichuan peppercorns and goji berries, but also to handle various hard-grained fruits of different sizes, such as hawthorn and cherries. This multi-purpose design reduces the user's purchase cost and also makes the operation more flexible, resulting in a better user experience.

[0085] Specifically, the inlet adjusting member 25 is a movable plate with a locking structure, movably disposed on both sides of the inlet of the suction channel 22, for adjusting the size of the inlet of the suction channel 22 during use. Furthermore, the inlet adjusting member 25 is a metal plate, and its locking structure is a snap-fit ​​structure, a screw structure, or other locking structures known to those skilled in the art.

[0086] Furthermore, guide grooves can be provided on both sides of the inlet of the suction channel 22 to guide and limit the inlet adjustment component 25.

[0087] Optionally, refer to Figure 6 The main body 1 in this utility model includes a box body;

[0088] The power module 11 includes a power supply component 111 and a vacuum pump component 112 disposed inside the housing. The vacuum pump component 112 is located above the power supply component 111, and the power supply component 111 and the vacuum pump component 112 are electrically connected.

[0089] The collection module 12 includes a collection box 121 and a connecting pipe 122. The collection box 121 is disposed inside the box and is located on the side of the power supply component 111 and the vacuum pump component 112. One end of the connecting pipe 122 is connected to the collection box 121, and the other end is connected to the outlet of the suction channel 22.

[0090] The vacuum pump assembly 112 is connected to the interior of the collection box 121.

[0091] In this embodiment, the housing serves as the supporting foundation for the entire device, and the power module 11 and the collection module 12 are rationally arranged inside. The power supply component 111 (such as a high-capacity battery) in the power module 11 provides power to the vacuum pump component 112. When the vacuum pump component 112 is working, it generates a stable negative pressure in the collection box 121, which is transmitted to the suction channel 22 outlet of the suction head component 2 through the connecting pipe 122, forming the power source for sucking up the fruit. The design of placing the collection box 121 on the side of other components conforms to the natural movement direction of airflow and fruit particles, which is conducive to the smooth settling of the fruit to the bottom of the box after it is sucked up. It avoids the risk of blockage caused by complex pipelines, and also avoids the problem of the heavy collection box 121 putting too much pressure on other components when a large number of fruits are loaded during use.

[0092] In this embodiment, the power and collection functions are condensed into a single unit, making the entire device compact, easy to move and store, and very suitable for transfer and operation in complex environments such as fields and orchards.

[0093] Furthermore, refer to Figure 7 In this embodiment, the collection box 121 has a height sensor 13, and a reminder component 14 is provided on the upper side of the box body 1. The reminder component 14 and the height sensor 13 are electrically connected. When the fruit in the collection box 121 reaches the height of the height sensor 13, the reminder component 14 outputs a corresponding signal. In use, when the fruit in the collection box 121 reaches the height of the height sensor 13, it means that the collection box 121 is about to be full. At this time, it is not advisable to continue picking. The reminder component 14 can remind the user that the collection box 121 is about to be full, so that picking can be stopped in time to avoid the collection box 121 overflowing or crushing the fruit at the bottom.

[0094] Specifically, the alert component 14 may include a microprocessor and an audible and visual alarm. The microprocessor is electrically connected to the height sensor 13 and the audible and visual alarm, obtains electrical signals from the height sensor 13, and controls the audible and visual alarm to output a corresponding alarm signal based on the electrical signals.

[0095] Specifically, the microprocessor model can be selected from ARM LPC2103, Crested Ibis microprocessor or MSP430G2553.

[0096] Furthermore, in this embodiment, there are at least two connecting tubes 122 and at least two suction head assemblies 2. During use, multiple users can use at least two suction head assemblies 2 simultaneously to pick fruit, thereby improving picking efficiency.

[0097] Furthermore, the housing 1 is also provided with an air vent, through which the vacuum pump assembly 112 is connected to the outside. During operation, the extracted gas can be discharged to ensure a negative pressure environment inside the collection box 121. At the same time, a filter screen is provided at the position where the vacuum pump assembly 112 connects to the inside of the collection box 121 to prevent harvested fruits and other items from being sucked into the pump.

[0098] Optionally, the collection box 121 in this utility model is provided with a discharge valve at the lower end, and the inner wall of the collection box 121 has a flexible anti-collision layer.

[0099] In this embodiment, a flexible anti-collision layer is provided on the inner wall of the collection box 121. This layer cushions the fruit as it is sucked into the collection box 121, preventing damage from rigid collisions with the inner wall. This is especially important when harvesting fruits such as cherries, as excessive impact can damage the fruit and render it unsellable. Therefore, this invention uses a flexible anti-collision layer on the inner wall of the collection box 121 to avoid these problems. Specifically, the flexible anti-collision layer in this embodiment can be made of plastic, rubber, or other flexible materials. Additionally, a discharge valve is provided at the lower end of the collection box 121. During use, when a large amount of fruit has been collected in the collection box 121, a storage bag or box can be placed below the discharge valve. Opening the discharge valve allows the fruit to be discharged from the collection box 121 and transported to a washing or processing location for dumping. This avoids the hassle of manually and laboriously scooping the fruit out of the field. This design fully considers the needs of practical applications, greatly reduces the user's workload, and improves the overall efficiency of the harvesting process.

[0100] Optionally, refer to Figure 6 In this utility model, a rigid sleeve 123 is provided on the part of the connecting pipe 122 near the outlet of the suction channel 22.

[0101] In this embodiment, a rigid sleeve is provided on the part of the connecting tube 122 near the outlet of the suction channel 22. This rigid structure plays a key supporting and guiding role, so that when the operator holds the suction head assembly 2 to perform picking actions at various angles and directions, this part of the connecting tube 122 will not collapse or twist due to frequent bending, thus ensuring that the airflow channel is always unobstructed. The rigid sleeve is also convenient for the user to hold and apply force, and can more accurately deliver the suction head assembly 2 to the vicinity of the target fruit, realizing a good human-machine operation, protecting the hose from damage, and improving the accuracy and comfort of picking.

[0102] Optionally, the lower side of the box body in this utility model is provided with multiple sets of movable wheels, which are respectively located at the corners of the lower side of the box body.

[0103] In this embodiment, multiple sets of wheels are provided on the lower side of the box and are arranged at the corners of the box. This design allows the operator to easily drag or push the box body, which has a certain weight and integrates a power and collection system. The equipment can be smoothly transferred between different plants in the orchard without repeated carrying or lifting, which greatly reduces the physical exertion of equipment transportation. It is particularly suitable for mobile operations in large orchards and fully reflects the humanization and practicality of modern agricultural machinery design.
