Description

Technical Field

[0001] This application relates to the field of harvesting tools, and in particular to an electric harvester for privet fruit. Background Technology

[0002] Privet fruit, a traditional Chinese medicinal herb, possesses various benefits such as tonifying the liver and kidneys, improving eyesight, and darkening hair. Its medicinal value is recorded in classic works such as the *Compendium of Materia Medica*. Modern research further indicates that privet fruit is rich in oleanolic acid, ursolic acid, amino acids, and various trace elements, exhibiting bioactivities such as enhancing immunity, lowering blood sugar, and anti-aging, leading to a continuously growing market demand. However, privet fruit typically grows on branches at a height of 4-7 meters, and currently, harvesting mainly relies on manual labor, which is inefficient and poses risks associated with working at heights. To improve harvesting efficiency, some harvesters directly break off fruit branches, resulting in a significant decrease in yield the following year and generating a large amount of leaf and branch waste, increasing the subsequent cleanup burden. Existing harvesting methods are not only labor-intensive and unsafe but also seriously affect the sustainable use of resources. Therefore, there is an urgent need to develop an efficient, safe, and minimally damaging harvesting device to solve the key technical problems in privet fruit harvesting.

[0003] Application content

[0004] This application proposes an electric harvester for privet fruit to solve the aforementioned problems.

[0005] The technical solution of this application is implemented as follows:

[0006] An electric privet harvester includes a support rod, one end of which is fixed with a handle tube, and the other end of which is detachably equipped with a harvesting mechanism. The support rod has a hollow structure, and a control switch for driving the harvesting mechanism to harvest privet fruit is fixed on the outer wall of the handle tube. The cable connecting the harvesting mechanism and the control switch is hidden inside the support rod. A harvesting cage is installed outside the harvesting mechanism, and a collection net bag for collecting privet fruit is nested inside the harvesting cage.

[0007] Furthermore, it also includes a storage battery, which is electrically connected to the harvesting mechanism via the control switch.

[0008] Furthermore, the support rod is composed of multiple hollow tubular components nested together in sequence, and the length of the support rod is adjustable from 1 to 4 meters.

A fully penetrating mounting hole is formed on the side wall of the auxiliary fixing post. The fixing clamp, the auxiliary fixing post, and the fixing ring are fixed together by a locking screw. An internal thread matching the external thread on the locking screw is formed in the mounting hole of the auxiliary fixing post away from the head of the locking screw.

[0010] Furthermore, the power output shaft of the electric motor is formed with a flat mounting part for mounting the harvesting tooth. The harvesting tooth includes a fixing part, and a slot is formed in the middle of the fixing part to cooperate with the flat mounting part. At least two support parts are fixed in an array on the outer circumference of the fixing part. The end of the support part away from the fixing part is bent towards the opening of the harvesting cage to form a striking part.

[0011] Furthermore, the handle sleeve includes a hollow cylinder, the battery is installed inside the cylinder, a charging socket electrically connected to the battery is embedded at one end of the cylinder near the support rod, a support sleeve is installed between the battery and the cylinder, the support sleeve is provided with a plurality of heat dissipation channels along its length, an installation hole is opened at the other end of the cylinder, a cover is threaded onto the open end of the cylinder, and heat dissipation holes are opened on the end face of the cover and on the side wall of the cylinder.

[0013] Furthermore, the support sleeve includes several thermally conductive pads, which are fixed together by several elastic ropes to form a ring structure that fits around the outside of the battery.

[0014] Furthermore, an auxiliary hand-holding device is fixed on the outer wall of the cylinder for more comfortable hand-holding. The auxiliary hand-holding device includes a hoop and a handle rod. There are two hoops, which are nested at both ends of the outer wall of the cylinder. The handle rod is fixed to the outer wall of the two hoops by two crossbars. The handle rod is a hollow structure with open ends. An extension rod is inserted into one end of the handle rod. Screws that limit the position of the extension rod are installed on the outer wall of the handle rod. A rubber handle is fixed to the outer end of the extension rod.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] like Figures 1-3 As shown, the electric privet harvester includes a support rod 3. One end of the support rod 3 is threaded or snap-fitted to a handle cylinder 1 to provide a stable grip and facilitate disassembly and maintenance. The other end of the support rod 3 is threaded to a harvesting mechanism 4 for easy replacement or repair of the harvesting components. The support rod 3 has a hollow structure to hide and protect the internal cables from external environmental damage. A control switch 2 for driving the harvesting mechanism 4 to harvest privet is fixed on the outer wall of the handle cylinder 1. The cable connecting the harvesting mechanism 4 and the control switch 2 is hidden inside the support rod 3 to reduce operational interference and improve safety. A harvesting cage 5 is installed outside the harvesting mechanism 4 for initial fruit collection and to prevent splashing. A collection net bag 6 for collecting privet is nested inside the harvesting cage 5 to facilitate centralized collection and transfer of the fruit.

[0033] As another preferred embodiment of the present invention, such as Figure 4 , Figure 9 As shown, it also includes a storage battery 12, which is electrically connected to the harvesting mechanism 4 via a control switch 2, providing an independent power supply for the electric motor 41, enhancing the portability and outdoor operation capability of the equipment. The storage battery 12 can be a lead-acid battery with an output voltage of 12V.

[0034] As another preferred embodiment of the present invention, such as Figure 3As shown, the support rod 3 is composed of 3-4 hollow tubes nested together in sequence, and their relative positions are fixed by threads, conical spinning caps or elastic pins. The length of the support rod 3 is adjustable from 1 to 4 meters to meet the harvesting needs of fruit tree canopies at different heights, improve harvesting efficiency and reduce the risk of climbing operations. The support rod 3 can be made of lightweight aluminum rods or rigid plastic tubes to ensure support strength while reducing weight.

[0035] As another preferred embodiment of the present invention, such as Figures 6-7 As shown, the harvesting mechanism 4 includes an electric motor 41 and a fixing screw 47. Harvesting teeth 46 are mounted on the power output shaft of the electric motor 41 and are limited by a nut. The fixing screw 47 is threaded onto the end of the support rod 3, enabling quick installation and disassembly of the harvesting mechanism 4. A fixing ring 44 is formed at the end of the fixing screw 47 away from the support rod 3. A fixing clamp 42 is welded and fixed to the outer wall of the electric motor 41. The harvesting cage 5 is welded to the outer wall of the fixing clamp 42. An auxiliary fixing post 43 is fixed at each end of the fixing clamp 42. The auxiliary fixing post 43 has a fully penetrating mounting hole formed on its side wall. The fixing clamp 42, the auxiliary fixing post 43, and the fixing ring 44 are fixed together by the locking screw 45 to form a stable three-point support structure, ensuring that the electric motor 41 does not shake during operation. The mounting hole of the auxiliary fixing post 43, which is away from the head of the locking screw 45, has an internal thread that matches the external thread on the locking screw 45. By tightening the locking screw 45, the angle of the electric motor 41 can be finely adjusted to optimize the picking posture and adapt to the picking needs of different fruits.

[0036] As another preferred embodiment of the present invention, such as Figures 6-8 As shown, a flat mounting part 401 for mounting harvesting teeth 46 is formed on the power output shaft of the electric motor 41. The harvesting teeth 46 include a fixing part 461. A slot 462 is formed in the middle of the fixing part 461 to cooperate with the flat mounting part 401 to prevent the harvesting teeth 46 from slipping during high-speed rotation. At the same time, this mounting structure facilitates the quick installation and replacement of the harvesting teeth 46. At least two support parts 463 are fixed in an array on the outer circumference of the fixing part 461. The end of the support part 463 away from the fixing part 461 is bent towards the opening of the harvesting cage 5 to form a striking part 464. The high-speed rotating striking part 464 applies mechanical impact force to the privet fruit, causing the fruit to fall off the fruit stem, improving harvesting efficiency and reducing damage to the fruit.

[0037] As another preferred embodiment of the present invention, such as Figure 1 , Figure 4As shown, the handle cylinder 1 includes a hollow cylinder 11, and a battery 12 is installed inside the cylinder 11, realizing the integrated design of the power supply and the main structure, reducing the entanglement of external cables. The end of the cylinder 11 near the support rod 3 is embedded with a charging socket 17 that is electrically connected to the battery 12, which facilitates the charging operation of the battery 12. A support sleeve 13 is installed between the battery 12 and the cylinder 11 to fix the battery 12 and provide a heat dissipation channel. The support sleeve 13 is provided with several heat dissipation channels along the length direction to enhance the air circulation around the battery 12 and prevent overheating. The other end of the cylinder 11 is provided with a mounting hole, and a cover 14 is installed on the open end of the cylinder 11 by thread, which facilitates the installation and replacement of the battery 12. Heat dissipation holes 16 are provided on the end face of the cover 14 and the side wall of the cylinder 11 to further improve the heat dissipation effect.

[0038] As another preferred embodiment of the present invention, such as Figure 4 As shown, a cooling fan 15 is fixed on the inner wall of the cover 14 and electrically connected to the battery 12 via a control switch 2. This fan actively cools the battery 12, extending its service life and ensuring the equipment operates continuously and stably.

[0039] As another preferred embodiment of the present invention, such as Figure 5 As shown, the support sleeve 13 includes several thermally conductive pads 131. The thermally conductive pads 131 are fixed together by several elastic ropes 132 to form a ring structure that is sleeved on the outside of the battery 12. The thermally conductive pads 131 are made of thermally conductive material, which improves heat dissipation capacity while ensuring structural stability.

[0040] As another preferred embodiment of the present invention, such as Figure 1 , Figure 4 As shown, an auxiliary handheld device 7 is fixed on the outer wall of the cylinder 11 for more comfortable handheld operation. The auxiliary handheld device 7 includes a hoop 71 and a handle 72. There are two hoops 71, which are nested at both ends of the outer wall of the cylinder 11 to ensure the stability of the auxiliary handheld device 7. The handle 72 is fixed to the outer wall of the two hoops 71 by two crossbars. The handle 72 is a hollow structure with open ends. An extension rod 73 is inserted into one end of the handle 72 to extend the handle length and adapt to the usage habits of different operators. Screws are installed on the outer wall of the handle 72 to limit the position of the extension rod 73 and fix the extension length of the extension rod 73. A rubber handle 74 is fixed to the outer end of the extension rod 73 to provide a non-slip and comfortable grip experience and reduce operator fatigue.

[0041] As another preferred embodiment of the present invention, such as Figure 1 As shown, the auxiliary handheld device 7 also includes an auxiliary strap 75. The two ends of the auxiliary strap 75 are hooked to the two crossbars of the fixed handle rod 72 by two hooks. The operator can pass his arm through the auxiliary strap 75 to distribute the weight of the equipment and further improve the comfort and stability of long-term operation.

[0042] As another preferred embodiment of the present invention, such as Figure 4 As shown, a fixing groove 18 is formed on the outer wall of the cylinder 11 at the position corresponding to the hoop 71. The width of the fixing groove 18 is the same as the height of the hoop 71, which is used to limit and fix the hoop 71 to prevent the auxiliary handheld device 7 from rotating or shifting during use.

[0043] The working principle of this application is as follows: The electric harvester extends the harvesting mechanism 4 to the canopy of the fruit tree through the support rod 3. The operator starts the electric motor 41 through the control switch 2 on the handle cylinder 1. The electric motor 41 drives the harvesting teeth 46 to rotate at high speed. The striking part on the harvesting teeth 46 applies mechanical force after contacting the privet fruit, causing the fruit to fall off the fruit stem. The fallen fruit falls into the harvesting cage 5 and the external collection net bag 6 under the action of gravity, realizing the harvesting and temporary storage of the fruit. The length of the support 3 is adjustable to adapt to the harvesting needs of different heights. The angle of the electric motor 41 can be adjusted by the locking screw 45 to optimize the harvesting posture. The battery 12 provides power supply. The control switch 2 and the heat dissipation structure ensure the continuous and stable operation of the equipment. The auxiliary handheld device 7 can be used with the auxiliary belt 75 to distribute the operating load and improve the controllability and comfort of operation.
