Description

Technical Field

[0001] This utility model relates to the field of forest fruit harvesting technology, specifically a harvesting device for tall-stalk forest fruits. Background Technology

[0002] China is a major country with a long history of forestry and fruit cultivation, possessing the world's richest forestry and fruit resources, with more than 50 varieties, making it the world's most abundant and earning it the title of "Mother of Forestry and Fruits." With rapid economic development and continuous optimization of the agricultural industrial structure, forestry and fruit industry has gradually become a major industry and important economic pillar for farmers to increase their income and achieve prosperity. It has not only brought significant economic benefits to my country, but also played an important role in ecological protection, achieving a win-win situation for both economic and ecological benefits. Facing international competition, China's forestry and fruit industry has demonstrated strong international competitiveness with its unique advantages and huge development potential. However, the intensive planting model implemented in most orchards in my country, with its limited operating space, makes it difficult to directly apply large-scale and efficient harvesting machinery from abroad to existing orchards in my country. Therefore, my country's forestry and fruit harvesting methods still mainly rely on manual knocking and picking.

[0003] CN116849028A discloses a manual shoulder-mounted harvesting device and method for woody oil crops. This device uses high-pressure airflow to drive a clamp to reciprocate, thereby shaking the branches. Compared to a motor-driven method, this reduces the overall weight of the harvesting rod, lowering labor intensity. Furthermore, the discharged high-pressure airflow disperses leaves, facilitating the separation of fruit and leaves for easier harvesting. The entire device features a shoulder-mounted design, allowing for flexible and convenient operation on both mountainous and flat terrain.

[0004] Existing technologies often utilize high-powered fans to generate high-intensity airflow, which is then redirected by guides to act on fruit trees, causing the branches to sway. When the intensity of the airflow and the swaying inertia of the fruit exceed the connecting force of the fruit stalk, the fruit falls into the collector. However, this method may result in excessive wind force, leading to branch breakage, leaf drop, and other issues that could affect the growth of the fruit trees and consequently reduce the fruit yield in the following year. Therefore, we need a harvesting device for tall-stalked forest fruits. Utility Model Content

[0027] This utility model embodiment provides a harvesting device for tall-stalked fruit trees, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the assembly includes a first telescopic rod 1, a handle assembly 2 on the outer wall of the first telescopic rod 1, a second telescopic rod 3 movably connected to one end of the first telescopic rod 1, a third telescopic rod 4 movably connected to one end of the second telescopic rod 3, a bottom shell 5 fixedly connected to one end of the third telescopic rod 4, a top shell 6 bolted to the top of the bottom shell 5, and a harvesting assembly 7 disposed inside the bottom shell 5. The handle assembly 2 includes a mounting sleeve 201, a rotating shaft 202 movably connected to one end of the mounting sleeve 201, and a handgrip 203 fixedly connected to one end of the rotating shaft 202. The mounting sleeve 201 is connected to the handle 203 via the rotating shaft 202. The handheld frame 203 forms a rotating structure, and there are two rotating shafts 202 on the handheld frame 203. The two rotating shafts 202 are symmetrically arranged about the vertical axis of the handheld frame 203, which enhances the connection between the mounting sleeve 201 and the rotating shafts 202. This allows the mounting sleeve 201 to rotate on the handheld frame 203 by means of the rotating shafts 202, and it can be used by the operator for handheld use. A threaded sleeve 204 is fixedly connected to the outer wall of the mounting sleeve 201. A self-locking screw 205 is connected to the internal thread of the threaded sleeve 204. The mounting sleeve 201 is connected to the self-locking screw 205 through the threaded sleeve 204.

The inner wall of the threaded sleeve 204 fits snugly against the outer wall of the self-locking screw 205, enhancing the connection between them. This allows the self-locking screw 205 to rotate within the threaded sleeve 204 and is securely fastened within the mounting sleeve 201. The overall length of the harvesting device can be adjusted according to the height of the fruit tree, and it can be tightened using a screw mechanism when connecting the second telescopic rod 3 to the first telescopic rod 1. When operating simultaneously with splicing, one hand can hold the holding frame 203 and the other hand can hold the tail end of the first telescopic rod 1. By pressing down on the tail end of the first telescopic rod 1, the harvesting device will tilt. The first telescopic rod 1 can be tilted by the holding frame 203 under the action of the two rotating shafts 202. This allows for quick adjustment of the height and position of the toothed rod 712 on the bracket 710. In addition, the handle assembly 2 is positioned and installed in the threaded sleeve 204 by the self-locking screw 205. The position of the holding frame 203 can be adjusted according to the usage, improving the practicality of the harvesting device.

[0028] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the harvesting assembly 7 includes a motor housing 701, inside which a brushless motor 702 is fixedly connected. The output shaft of the brushless motor 702 is fixedly connected to a gear shaft 703 via a coupling. A drive gear 704 is meshed with the outer wall of the gear shaft 703. The brushless motor 702 and the drive gear 704 form a rotating structure through the gear shaft 703 and the drive gear 704. The top of the gear shaft 703 is connected to the output end of the brushless motor 702, and the outer wall of the gear shaft 703 is connected to the outer wall of the drive gear 704, thus strengthening the connection between the brushless motor 702 and the gear shaft 703. This allows the brushless motor 702 to drive the drive gear 704 by driving the gear shaft 703. 04 rotates. An eccentric wheel 705 is fixedly connected to the top of the drive gear 704. A first bearing 706 is fixedly connected to the outer wall of the eccentric wheel 705. The drive gear 704 forms a movable structure through the eccentric wheel 705 and the first bearing 706. The bottom of the eccentric wheel 705 is fixed to the top of the drive gear 704, and the outer wall of the eccentric wheel 705 is connected to the inner wall of the first bearing 706, which strengthens the connection effect between the drive gear 704 and the eccentric wheel 705. This allows the drive gear 704 to drive the eccentric wheel 705 to rotate when it rotates. A connecting rod 707 is movably connected to the outer wall of the first bearing 706, and a second bearing 708 is fixedly connected inside the drive gear 704. One end of the connecting rod 707 is movably connected to the first rotating shaft 709, one end of the first rotating shaft 709 is movably connected to the bracket 710, and the middle of the bracket 710 is movably connected to the second rotating shaft 711. The second rotating shaft 711 is rotatably connected to the bottom shell 5 and the top shell 6, so that the bracket 710 can rotate or swing relative to the bottom shell 5 and the top shell 6 with the second rotating shaft 711 as the axis.

[0029] The connecting rod 707 is provided in two sets, each set equipped with a bracket 710, a guide support frame 713, and several toothed rods 712. The bracket 710 is a long strip structure, one end of which is rotatably connected to the connecting rod 707 via a first rotating shaft 709, and the middle of the bracket 710 is rotatably connected to the bottom shell 5 and the top shell 6 via a second rotating shaft 711. Several toothed rods 712 are threadedly connected to one side of the bracket 710, preferably 4-5. The toothed rods 712 are long and thin rod structures made of flexible materials such as rubber. The support frame 710 is also equipped with a guide support frame 713. The guide support frame 713 is a bent piece with several through holes. The through holes can be adapted to the diameter of the toothed rod 712. The bent arrangement of the guide support frame 713 allows the several toothed rods 712 to be not in the same plane, and to generate a certain degree of branching in space. The function is to distribute the several toothed rods 712 in a staggered manner in space, so as to better fit the branches of different shapes, or directly pass through the branches to contact and tap the fruit for harvesting.

[0030] The connecting rod 707 forms a movable structure with the bracket 710 through the first rotating shaft 709. The bottom end of the first rotating shaft 709 is movably connected to one end of the connecting rod 707, and the top of the first rotating shaft 709 is fixedly connected to the bottom of the bracket 710. This strengthens the connection between the first rotating shaft 709 and the connecting rod 707, allowing the eccentric wheel 705 to pull the connecting rod 707 to swing back and forth when it rotates. The connecting rod 707 can also pull the first rotating shaft 709 to move, which can cause the bracket 710 to swing back and forth.

[0031] Working Principle: During use, the overall length of the harvesting device can be adjusted according to the height of the fruit tree. When connecting the second telescopic rod 3 to the first telescopic rod 1, it is secured and spliced ​​using a screw mechanism. Simultaneously, during operation, one hand holds the holding frame 203, and the other hand holds the tail end of the first telescopic rod 1. By pressing down on the tail end of the first telescopic rod 1, the harvesting device tilts. The first telescopic rod 1, under the action of the two rotating shafts 202, is tilted using the holding frame 203, allowing for quick adjustment of the height and position of the toothed rod 712 on the support 710. Furthermore, the self-locking screw 205 positions and installs the handle assembly 2 within the threaded sleeve 204. The position of the holding frame 203 can be adjusted according to usage, improving the practicality of the harvesting device. Additionally, by starting... The brushless motor 702 drives the gear shaft 703 to rotate, which in turn drives the drive gear 704 to rotate. The drive gear 704 then drives the eccentric wheel 705 to rotate. When the eccentric wheel 705 rotates, it pulls the connecting rod 707 to swing back and forth. This allows the connecting rod 707, under the action of the first bearing 706, to pull the bracket 710 to vibrate back and forth on the first rotating shaft 709 at the bottom. Furthermore, the bracket 710, supported by the second rotating shaft 711, can swing within the bottom shell 5, causing multiple spatially staggered toothed rods 712 to swing. The excitation force is transmitted from the toothed rods 712 to the branches, causing the branches and fruits to vibrate. At the same time, the staggered toothed rods 712 can fit the branches of different shapes or directly pass through the branches to contact and tap the fruits, thus realizing the fruit harvesting operation.

[0032] It should be noted that the above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
