Description

Technical Field

[0001] This utility model relates to the technical field of agricultural harvesting equipment, and in particular to a handheld goji berry harvesting device. Background Technology

[0002] Goji berries are a plant that can be used for both medicinal and culinary purposes, and are rich in many components that are beneficial to the human body.

[0003] Currently, goji berries are mainly harvested manually, but manual harvesting is labor-intensive and inefficient. Although a large-scale mechanical vibrating harvesting device has emerged that shakes the branches and twigs to cause the goji berries to fall off and collect them, this harvesting method causes significant damage to the goji berry trees, resulting in a large number of fallen berries. Furthermore, since goji berry cultivation in the main producing areas of China is still dominated by small-scale farmers, the spacing between goji berry trees in the fields is small, and the cost of large-scale mechanical vibrating harvesting equipment is high, it is difficult to promote in actual production. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a handheld goji berry harvesting device that can reduce labor intensity, improve harvesting efficiency, avoid damage to goji berries during harvesting, and is suitable for small farmers.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A handheld goji berry harvesting device includes a collection module, a handheld module, a separation and blocking module, a cutting module, and a power supply system for powering the cutting module;

[0007] The handheld module is connected to the collection module;

[0008] The separation and blocking module is positioned above the collection module, and the separation and blocking module has a root cutting space inside;

[0009] The cutting module is located within the root and stem cutting space. It includes a toothed chain and a multi-wheel drive assembly. The toothed chain and the multi-wheel drive assembly cooperate to form at least two line cutting areas, and there is an angle between the transmission direction of the toothed chain and the direction in which the wolfberry root and stem enter the root and stem cutting space.

[0010] In this technical solution, the goji berry harvester holds a handheld module and brings it close to the goji berries hanging on the branches, allowing the goji berry stems to enter the stem cutting space. The berries are blocked outside the cutting space by a separation and blocking module. Then, the cutting module cuts the goji berry stems, causing the berries to fall into the collection module. This technical solution reduces labor intensity, avoids damage to goji berries during harvesting, and is suitable for small-scale farmers. Furthermore, this solution uses wire cutting, allowing for simultaneous cutting of multiple goji berry stems, thus increasing cutting efficiency and significantly improving harvesting efficiency.

[0011] Furthermore, it also includes a bracket for connecting to the collection module;

[0012] Both the separation blocking module and the cutting module are mounted on the frame and are tilted relative to the collection module.

[0013] In this technical solution, to facilitate the entry of wolfberry roots into the root cutting space, when harvesting wolfberries, the separation blocking module, cutting module, and frame are all in a horizontal state, while the collection module is in an inclined state. This allows the wolfberry fruit whose roots have been cut to fall into the collection module and quickly slide to the end of the collection module away from the cutting module, thus avoiding affecting the subsequent cutting of wolfberry roots.

[0014] Furthermore, the multi-wheel transmission assembly includes a driving wheel, several driven wheels, a driving wheel mounting base, a motor, and a motor mounting base;

[0015] The drive wheel mounting base is fixedly connected to the frame base;

[0016] The driving wheel and several driven wheels are rotatably mounted on the driving wheel mounting base, forming a symmetrical driving wheel array;

[0017] The serrated chain meshes with the driving wheel and several driven wheels to form a rhombus with four equal sides. The two sides of this rhombus facing the entrance of the root cutting space serve as the cutting edges of the corresponding line cutting areas, and there is an angle between the rhombus and the direction in which the wolfberry root enters the root cutting space.

[0018] The motor is fixed to the frame via a motor mounting base and connected to the drive wheel, thereby driving the toothed chain to rotate through the cooperation of the drive wheel and several driven wheels.

[0019] Furthermore, the separation and blocking module includes a separation comb and a blocking comb;

[0020] The separating comb is placed above the root cutting space to separate the roots of multiple goji berries, preventing the roots of multiple goji berries from clustering together in the root cutting space, thereby reducing the difficulty of cutting goji berry roots with the toothed chain.

[0021] The blocking comb is placed below the root and stem cutting space to block the goji berry fruit from entering the root and stem cutting space, thus preventing the cutting module from damaging the goji berry fruit.

[0022] Furthermore, the separation and blocking module also includes auxiliary connectors;

[0023] The separating comb is detachably connected to the frame via an auxiliary connector;

[0024] The blocking comb is detachably connected to the frame.

[0025] In addition to harvesting goji berries, this technical solution can also harvest different types of agricultural fruits by replacing the separating combs and blocking combs of different sizes.

[0026] Furthermore, the bracket is provided with a slot;

[0027] Both the auxiliary connector and the blocking comb are provided with inserts, and they are detachably connected by engaging with the corresponding slots on the frame through their respective inserts.

[0028] Furthermore, the auxiliary connector is provided with a guide to guide the wolfberry rootstock into the rootstock cutting space.

[0029] Furthermore, the frame is rotatably connected to the collection module. When the frame rotates to the side away from the inside of the collection module, it not only facilitates the installation of the separation blocking module and the cutting module on the frame, but also facilitates the cleaning of the separation blocking module and the cutting module, avoiding the accumulation of debris and fallen leaves.

[0030] Furthermore, the motor mounting base is equipped with a snap-fit ​​assembly, which is detachably connected to the collection module through the snap-fit ​​assembly, thereby restricting the rotation of the frame.

[0031] Furthermore, the collection module is provided with through holes;

[0032] The buckle assembly includes a first hook, a second hook, and a spring;

[0033] The end of the first hook away from its hook portion is connected to the motor mounting base, and one end of the hook portion passes through the through hole;

[0034] The second hook is connected to the motor mounting base at one end away from its hook portion, and the other end of the hook portion passes through the through hole;

[0035] The first hook and the second hook are arranged in a mirror image, and the spring is located between the two and close to one end of the hook.

[0036] The first and second hooks engage with the through-hole buckle under the action of the spring.

[0037] Compared with existing technologies, the principles and advantages of this technical solution are as follows:

[0038] 1. In this technical solution, the goji berry harvester holds a handheld module and brings the collection module close to the goji berries hanging on the branches, allowing the goji berry stems to enter the stem cutting space. The goji berries are blocked outside the cutting space by a separation and blocking module. Then, the cutting module cuts the goji berry stems, causing the berries to fall into the collection module. This technical solution reduces labor intensity, avoids damage to goji berries during harvesting, and is suitable for small-scale farmers. Furthermore, this technical solution uses wire cutting, allowing for simultaneous cutting of multiple goji berry stems, thus improving cutting efficiency and significantly increasing harvesting efficiency.

[0039] 2. In this technical solution, to facilitate the entry of wolfberry roots into the root cutting space, when harvesting wolfberries, the separation blocking module, cutting module, and frame are all in a horizontal state, while the collection module is in an inclined state. This allows the wolfberry fruit whose roots have been cut to fall into the collection module and quickly slide to the end of the collection module away from the cutting module, thus avoiding affecting the subsequent cutting of wolfberry roots.

[0040] 3. In this technical solution, the separating comb is placed above the root and stem cutting space to separate the roots and stems of multiple goji berries, preventing them from clustering together and entering the cutting space, thereby reducing the difficulty of cutting the goji berry roots and stems with the toothed chain. The blocking comb is placed below the root and stem cutting space to block the goji berry fruit from entering the cutting space, preventing the cutting module from damaging the goji berry fruit.

Detailed Implementation

[0052] The present invention will be further described below with reference to two specific embodiments:

[0053] Example 1

[0054] like Figures 1 to 8 As shown, the handheld goji berry harvesting device described in this embodiment includes a collection module 1, a handheld module 2, a separation and blocking module, a cutting module, a frame 4, and a power supply system for supplying power to the cutting module.

[0055] The power system includes a controller, a power supply, and a control switch 20; the collection module 1 is a collection box with an open top; the handheld module 2 is a handle connected to one end of the collection box, and the control switch 20 is located on the handle; the controller and the power supply are both installed inside the handle; the controller uses an STM32 chip and is electrically connected to the power supply and the control switch 20; the frame 4 is rotatably connected to the end of the collection box away from the handle; the collection box has a through hole 16 located below the frame 4.

[0056] Both the separation blocking module and the cutting module are mounted on the frame 4 and are inclined relative to the collection module 1. The separation blocking module has a root cutting space inside. The cutting module is located in the root cutting space and includes a toothed chain 3 and a multi-wheel transmission assembly. The toothed chain 3 and the multi-wheel transmission assembly cooperate to form two line cutting areas, and there is an angle between the transmission direction of the toothed chain 3 and the direction in which the wolfberry root enters the root cutting space.

[0057] The separation and blocking module includes a separation comb 5, a blocking comb 6, and an auxiliary connector 7. The separation comb 5 has a 2mm spacing between its teeth (used to block branches and goji berry fruits from entering). The separation comb 5 is detachably connected to the frame 4 via the auxiliary connector 7 and is positioned above the root cutting space (when connected to the frame 4) to separate the roots of multiple goji berries, preventing multiple goji berry roots from clustering together and entering the root cutting space, thereby reducing the difficulty of cutting goji berry roots through the toothed chain 3. The blocking comb 6 is positioned below the root cutting space and is detachably connected to the frame 4 to block the goji berry fruits outside the root cutting space, preventing the cutting module from damaging the goji berry fruits.

[0058] Specifically, in this embodiment, the frame 4 is provided with a slot 8; the auxiliary connector 7 and the blocking comb 6 are both provided with inserts 9, and the two are connected to the corresponding slots 8 of the frame 4 through their respective inserts 9 to achieve a detachable connection.

[0059] The auxiliary connector 7 is provided with a guide part 10 to guide the wolfberry rhizome into the rhizome cutting space.

[0060] Specifically, in this embodiment, the multi-wheel transmission assembly includes a drive wheel 11, three driven wheels 12, a drive wheel mounting base 13, a motor 14, and a motor mounting base 15. The drive wheel mounting base 13 is fixedly connected to the frame 4. The drive wheel 11 and the three driven wheels 12 are rotatably mounted on the drive wheel mounting base 13, forming a symmetrical drive wheel array. The toothed chain 3 meshes with the drive wheel 11 and the three driven wheels 12, forming a rhombus with four equal sides. The two sides of this rhombus facing the entrance of the root cutting space serve as the cutting edges of the corresponding wire cutting areas, and there is an angle between the rhombus and the direction in which the wolfberry root enters the root cutting space. The motor 14 is fixed to the frame 4 through the motor mounting base 15, and is electrically connected to the controller and the drive wheel 11, thereby driving the toothed chain 3 to rotate through the cooperation of the drive wheel 11 and the several driven wheels 12. The wiring between the motor 14 and the controller is laid at the bottom of the collection box.

[0061] The motor mounting base 15 is equipped with a snap-fit ​​assembly, which is detachably connected to the collection module 1 to restrict the rotation of the frame 4.

[0062] Specifically, in this embodiment, the snap-fit ​​assembly includes a first hook 17, a second hook 18, and a spring 19; the end of the first hook 17 away from its hook portion is connected to the motor mounting base 15, and one end of the hook portion passes through the through hole 16; the end of the second hook 18 away from its hook portion is connected to the motor mounting base 15, and one end of the hook portion passes through the through hole 16; the first hook 17 and the second hook 18 are arranged in a mirror image, and the spring 19 is disposed between the two and close to one end of the hook portion of both; the first hook 17 and the second hook 18 are snap-fitted into the through hole 16 under the action of the spring 19.

[0063] The working principle of this embodiment is as follows:

[0064] The goji berry harvester holds a handle and brings the collection box close to the goji berries hanging on the branches, so that the goji berry stems enter the stem cutting space, while the goji berry fruits are blocked outside the stem cutting space by the blocking comb 6. Then, the control switch 20 is pressed, and the controller controls the motor 14 to work. The motor 14 then drives the drive wheel 11 to rotate, and the drive wheel 11 drives the driven wheel 12 and the toothed chain 3 to rotate, thereby cutting the goji berry stems and causing the goji berry fruits to fall into the collection box.

[0065] This embodiment reduces labor intensity and avoids damage to goji berries during harvesting, making it suitable for small-scale farmers. Furthermore, this embodiment uses a wire cutting method, allowing for the simultaneous cutting of multiple goji berry rhizomes, thus improving cutting efficiency and significantly increasing harvesting efficiency.

[0066] In addition, in this embodiment, to facilitate the entry of the wolfberry roots into the root cutting space, when picking wolfberries, the separation blocking module, the cutting module, and the frame 4 are all in a horizontal state. At the same time, the collection box is in an inclined state, so that the wolfberry fruit whose roots have been cut falls into the collection module 1 and quickly slides to the end of the collection module 1 away from the cutting module, so as to avoid affecting the subsequent cutting of wolfberry roots.

[0067] The separating comb 5 is detachably connected to the frame 4 via the auxiliary connector 7, and the blocking comb 6 is detachably connected to the frame 4. This allows for the harvesting of different types of agricultural fruits in addition to goji berries, by replacing the separating comb 5 and blocking comb 6 with different sizes.

[0068] The frame 4 is rotatably connected to the collection module 1. When the frame 4 rotates to the side away from the inside of the collection module 1, it not only facilitates the installation of the separation blocking module and the cutting module on the frame 4, but also facilitates the cleaning of the separation blocking module and the cutting module, avoiding the accumulation of debris and fallen leaves.

[0069] Finally, in this embodiment, when the handheld goji berry harvesting device is in the harvesting state, the motor mounting base 15 is connected to the collection box through the buckle assembly, restricting the rotation of the frame 4. At this time, the first hook 17 and the second hook 18 are respectively snapped onto the two sides of the through hole 16 under the action of the spring 19. When the frame 4 needs to rotate, the first hook 17 and the second hook 18 are squeezed with two fingers respectively, so that the first hook 17 and the second hook 18 leave the two sides of the through hole 16 respectively, realizing the separation of the motor mounting base 15 from the collection box.

[0070] Example 2

[0071] Compared with Embodiment 1, the difference is that the power system in this embodiment includes a power supply and a control switch 20. The control switch 20 is connected in series between the power supply and the motor 14, and the wiring between the control switch 20 and the motor 14 is laid at the bottom of the collection box.

[0072] The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all changes made in accordance with the shape and principle of this utility model should be covered within the protection scope of this utility model.
