Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nut picking, in particular to an auxiliary nut picking device through fork pulling and shaking. BACKGROUND

[0002] In the field of agriculture, nuts, as an important crop with both economic and nutritional value, the development of mechanized harvesting technology has a key significance to improve industry efficiency and reduce labor costs. With the continuous expansion of nut planting scale, the traditional manual picking method is time-consuming and laborious, high in cost, and easily affected by season and labor supply, which has been difficult to meet the needs of large-scale production. Therefore, the mechanized harvesting equipment with vibration picking as the core gradually becomes the mainstream application direction in the industry.

[0003] The core principle of vibration picking technology is to transmit high-frequency vibration generated by the device to the branches where nuts are located, so that mature nuts are separated from the fruit stem due to inertia and fall to the ground, and then the subsequent picking device is used to complete the collection. However, in the actual application process, this technology still faces multiple technical bottlenecks, making it difficult to balance the efficiency of harvesting and the integrity of nuts, which restricts the development of industrial scale.

[0004] Firstly, from the physical characteristics of nuts, there are obvious size differences in the same tree or the same batch of mature nuts - in addition to normal size mature nuts, there are also some mature nuts larger than normal size (referred to as "super large nuts"). When using the same vibration picking device, due to the differences in mass and inertia between super large nuts and normal nuts, the horizontal projection force on super large nuts is stronger during the vibration energy transmission process, and they will form a longer drop point when falling to the ground. While normal nuts are concentrated in a relatively close area below the trunk. The above scattered drop points directly lead to a significant increase in the coverage range of subsequent picking operations, not only prolonging the harvesting period, but also increasing the omission rate of manual or mechanical picking, causing hidden losses in nut yield, and also increasing the energy consumption and cost of the overall harvesting operation.

[0005] Secondly, the existing connection mode of the vibration picking and beating device and the branch has obvious defects. The current mainstream device adopts a fork prong structure to be directly clamped and fixed on the branch to be picked and beaten, and the vibration energy is transmitted to the branch through the fork prong. However, in the actual vibration process, on the one hand, the hard contact between the fork prong and the branch lacks a buffer structure, and high-frequency vibration easily causes scratches and extrusion damage to the bark of the branch, especially for fruit tree varieties with thin bark or brittle wood, which will affect the subsequent growth of the tree body, and even cause the yield to decrease next year; on the other hand, if there is dew, rain or exudate on the surface of the branch, the friction between the fork prong and the branch will be significantly reduced, and the vibration will easily slip - the vibration energy cannot be effectively transmitted to the branch, not only causing the nut shedding rate to decrease significantly, but also requiring repeated picking and beating, which seriously affects the picking and beating efficiency, and also causes additional damage to the surrounding branches or the device itself due to the accidental displacement of the fork prong during the slipping process.

[0006] In addition, the difference in the thickness of the fruit tree branches further exacerbates the application limitations of the picking and beating technology. During the growth of the fruit tree, the thickness of the branches is affected by factors such as tree age, growth location, nutrient supply, etc., and shows significant individual differences. When picking and beating nuts on thin branches, due to the lower degree of lignification and stronger flexibility of thin branches, they have strong vibration buffering capacity - when the device vibration energy is transmitted to the thin branches, the branches will consume most of the vibration energy through their own bending and swinging, resulting in a significant reduction in the effective vibration intensity transmitted to the nut stalk, making it difficult to break through the connection force threshold between the nut stalk and the branch, and thus causing mature nuts to not be able to be easily shed; the above situation not only leads to a low nut yield in the thin branch area, forming a "picking and beating blind area", but also increases the risk of breaking the thin branches due to the operator's blind increase of the vibration intensity to improve the shedding rate, further damaging the tree health, forming a vicious cycle of "low picking and beating efficiency - tree damage - yield reduction".

[0007] In summary, the existing nut vibration picking and beating technology has significant technical shortcomings in dealing with the size difference of nuts, the stability of branch connection and the adaptability of different thickness branches, and it is difficult to meet the needs of efficient, low-damage and large-scale nut picking. Therefore, developing a new type of vibration picking and beating technology that can solve the problem of scattered landing points, optimize the connection structure of branches, and adapt to different thickness branches, has become a key direction to promote the mechanization upgrade of the nut industry.

[0008] Therefore, the present application proposes an auxiliary nut picking and beating device that can be shaken by a fork to solve the above problems. SUMMARY

[0009] Therefore, the present application proposes an auxiliary nut picking and beating device that can be shaken by a fork to solve the above problems.

[0010] In order to achieve the above object, the present application provides the following technical scheme: an auxiliary nut picking device through fork pulling and swinging, comprising a hand-held rod and a component placement cavity fixedly connected at the top end, further comprising a first assembly; The first assembly comprises a shaft fixedly connected to the component placement cavity, a swing bar rotatably connected to the shaft, and a vertical groove fixedly connected to one end of the swing bar in the inner cavity of the component placement cavity. A driving device is fixedly connected in the component placement cavity, an L-shaped piece is fixedly connected to the shaft end of the driving device, and a straight slot is formed in the L-shaped piece. A driving screw is arranged in the straight slot, a horizontal moving rod is slidably connected in the straight slot, and the driving screw is in transmission connection with the horizontal moving rod. A sliding block is fixedly connected to the outer end of the horizontal moving rod, and the sliding block is slidably connected to the inner groove of the vertical groove.

[0011] As a preferred, a second assembly is further included; The second assembly includes a long condition fixedly connected to the outer end face of the swing bar, a sliding groove formed in the long condition, a sliding piece equidistantly slidably connected in the sliding groove, and a connecting column fixedly connected to the sliding piece in a symmetrical manner.

[0012] As a preferred, two tail ends of the connecting columns are fixedly connected with a long column rod, a recess is formed in the long column rod, and an inclined block is fixedly connected in the recess; Equidistantly fixedly connected with a telescopic rod A on the inner cavity wall of the long condition, an inclined slot is formed in the telescopic end of the telescopic rod A.

[0013] As a preferred, equidistantly fixedly connected with a fluid bin in the inner cavity of the long condition, a hole-containing disc is fixedly connected to one end of the fluid bin in the inner cavity; The fluid bin contains a non-Newtonian fluid.

[0014] As a preferred, a third assembly is further included; The third assembly comprises an electric control shaft seat fixedly connected to the sliding piece, the electric control shaft seat is composed of an electric control shaft and a fixed seat, and an annular groove is formed in the fixed seat; An inner column piece is arranged on the same straight line as the electric control shaft, a limiting groove is formed in one end of the inner column piece close to the electric control shaft seat, and the electric control shaft is inserted into the limiting groove; A spring is fixedly connected to the inner cavity wall of the limiting groove, and one end of the spring away from the inner cavity wall of the limiting groove is fixedly connected to the electric control shaft.

[0015] As a preferred, an outer shell piece is sleeved on the inner column piece, a limiting piece is fixedly connected in the inner cavity of the outer shell piece, and a telescopic rod B is rotatably connected to the inner cavity wall of the outer shell piece away from the electric control shaft seat.

[0016] As preferred, equidistantly fixed connection with a circular table piece is arranged on the telescopic shaft of the telescopic rod B, and a through slot is arranged on the inner column piece and the shell piece, and an outward expansion piece is slidably connected in the through slot.

[0017] Compared with the prior art, the present application provides an auxiliary nut picking device which is shaken by fork pulling, and has the following beneficial effects: 1. The present application adjusts the position of the horizontal moving rod to change the swing amplitude of the first assembly, and can bring the following benefits from the aspects of falling point range, picking operation and yield guarantee: The falling point coverage of nuts is effectively reduced: the first assembly indirectly changes the swing amplitude of the swing bar by adjusting the position of the horizontal moving rod in the linear slot of the L-shaped piece; the adjustable design can adapt to different swing states according to the characteristic differences between normal nuts and oversized nuts in the same tree or the same batch, and balance the horizontal projection force received by the two types of nuts during vibration picking; it can not only avoid the formation of too far falling points of oversized nuts due to excessive force, but also ensure that normal nuts fall stably in the reasonable area below the tree trunk, so that the falling points of all picked nuts are more concentrated, and the problem of falling point dispersion in the prior art is improved. The difficulty of subsequent picking operation is significantly reduced; the overall harvesting period is greatly shortened: since the falling point range of nuts is effectively concentrated, subsequent manual or mechanical picking operation does not need to expand the coverage area. The staff does not need to frequently move the position to adjust the picking range, and the mechanical picking equipment does not need to repeatedly adjust the operation path, reducing the invalid operation in the picking process, making the picking operation more targeted, and greatly reducing the difficulty of picking caused by the dispersion of falling points in the prior art; the picking time is further saved, and the overall harvesting period is shortened from the two key links of picking and picking.

[0018] The hidden loss of nut yield is effectively reduced: the concentration of falling points makes it easier for manual or mechanical picking to cover all nut falling areas, avoiding the situation that part of the nuts fall in remote areas and are missed due to the dispersion of falling points in the prior art; the missing rate of picking is significantly reduced, ensuring that the picked nuts can be fully recovered, reducing the hidden loss of yield, and protecting the economic benefits of the grower.

[0019] 2. The present application adjusts the distance between the fork pulling (i.e. the shell piece) to adapt to the thickness of the branch by the second assembly, which can bring the following benefits: Reduce the incidence of slip phenomenon, ensure the effective transmission of vibration energy: By adjusting the fork spacing, a more conformal and stable contact state between the fork and branches of different thicknesses can be formed, increasing the contact area and friction between them. Even in the presence of dew, rain or secretions on the surface of the branches, the problem of significantly reduced friction between the fork and the branches can be effectively alleviated, greatly reducing the slip phenomenon; the vibration energy generated by the device can be stably and efficiently transmitted to the branches, avoiding the problem of decreased nut drop rate caused by interrupted or lost energy transmission; Improve efficiency and reduce repetitive work: Since the vibration energy can be effectively transmitted to the branches, mature nuts can be successfully removed in one picking process, eliminating the need for repeated picking of the same branch due to insufficient energy transmission caused by slipping in the prior art; reducing the number of ineffective repetitive work steps, shortening the picking time for a single tree or a specific area, significantly improving overall picking efficiency and reducing the workload of workers; Avoid additional damage caused by slipping, reduce device and branch wear: When slipping, the fork is prone to accidental displacement, which can cause damage to surrounding healthy branches and often leads to deformation or damage of the fork structure due to uneven stress; the second component reduces the likelihood of accidental fork displacement, protecting surrounding branches from unnecessary damage and reducing the wear and tear of the fork components of the picking device, extending the service life of the device and reducing maintenance and replacement costs; Enhance the adaptability of the device to different tree varieties and growth states: The thickness of branches varies among different tree varieties, and even within the same tree, the thickness of branches at different locations varies; the second component's adjustable fork spacing design allows the picking device to adapt to a variety of tree varieties and branches in different growth states of the same tree, expanding the device's application range and improving its practicality and versatility.

[0020] 3、The third component of the present application can bring the following benefits through the expansion and rotation of the outer expansion piece: Eliminate the picking blind area in the thin branch area and improve the overall nut harvesting rate: The outer expansion piece in the third component can expand outward from the shell piece, adapting to the growth state of thin branches and fully contacting the nuts on the thin branches; when the shell piece rotates, adjacent outer expansion pieces rotate in different directions to remove the nuts on the thin branches, eliminating the need for vibration energy transmission to break through the fruit stem connection force threshold; the above design effectively solves the problem of insufficient effective vibration intensity in thin branches due to strong vibration damping capacity, making it difficult for mature nuts to fall off, completely eliminating the "picking blind area" in the thin branch area, allowing nuts on thin branches to be fully harvested, and significantly improving the overall nut harvesting rate; To avoid blindly increasing vibration intensity and protect the health of twigs and the tree: Since the nut-removing operation of the outer expansion piece can directly remove nuts, operators no longer need to blindly increase vibration intensity to improve the nut removal rate on twigs. This avoids the risk of twig breakage caused by high-intensity vibration, prevents twig damage from affecting subsequent growth, and thus protects the overall health of the tree. This breaks the vicious cycle of "low harvesting efficiency - tree damage - decreased yield," ensuring the fruit tree's subsequent fruiting capacity and stable yield. Reducing reliance on the lignification and flexibility of branches, thus expanding the equipment's applicability: In existing technologies, the harvesting effect is highly dependent on the vibration transmission ability of branches, resulting in poor adaptability to thin branches with low lignification and high flexibility. The third component, however, harvests nuts through a physical action of rubbing, without relying on the branches themselves to transmit vibration energy, reducing the equipment's dependence on the physical characteristics of branches. Whether it's thin branches with low lignification or branches with other characteristics, the equipment can effectively harvest nuts through the operation of the outer extension, significantly expanding the applicability of the harvesting equipment and improving its adaptability to branches in different growth stages.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example: Please refer to Figures 2 to 4 As shown: To address the problems mentioned in the technical solutions, this application provides an auxiliary nut harvesting device that uses a fork to shake, including: a hand handle 1 and a component placement cavity 2 fixedly connected to the top, and also includes: a first component 3; The first component 3 includes a shaft 301 fixedly connected to the component mounting cavity 2, a swing bar 302 rotatably connected to the shaft 301, and a vertical groove 303 fixedly connected to one end of the swing bar 302 located in the inner cavity of the component mounting cavity 2; a drive device 304 is fixedly connected inside the component mounting cavity 2, an L-shaped piece 305 is fixedly connected to the shaft end of the drive device 304, and a straight groove 306 is provided on the L-shaped piece 305; a drive screw 307 is provided in the straight groove 306, and a transverse rod 308 is slidably connected in the straight groove 306, and the drive screw 307 and the transverse rod 308 are connected in a transmission connection; a sliding block 309 is fixedly connected to the outer end of the transverse rod 308, and the sliding block 309 is slidably connected to the inner groove of the vertical groove 303.

[0026] in: The first component 3 is used for oscillating harvesting of nuts.

[0027] The inner groove of the vertical groove 303 is adapted to the sliding block 309.

[0028] The drive unit 304 can be implemented as an electric motor; the drive screw 307 is driven by the electric motor.

[0029] Adjusting the position of the horizontal moving rod 308 within the straight groove 306 can indirectly adjust the swing amplitude / range of the swing bar 302, thereby ensuring that when harvesting nuts of different sizes, the landing point of the nuts is still relatively concentrated, reducing the difficulty of subsequent picking operations and improving picking efficiency.

[0030] A further embodiment: Please refer to Figure 1 , Figures 5 to 8 As shown: The second component 4 includes a long condition 401, which is fixedly connected to the outer end face of the swing bar 302. A sliding groove 402 is provided on the long condition 401, and a sliding piece 403 is equidistantly connected in the sliding groove 402. A connecting post 404 is symmetrically fixedly connected to the sliding piece 403. A long rod 405 is fixedly connected to the tail ends of the two connecting posts 404. A groove is provided on the long rod 405, and an inclined block 406 is fixedly connected in the groove. A telescopic rod A407 is equidistantly fixedly connected to the inner wall of the long condition 401. An inclined groove 408 is provided on the telescopic end of the telescopic rod A407. A fluid chamber 409 is equidistantly fixedly connected to the inner cavity of the long condition 401. A perforated disc 410 is fixedly connected to one end of the long rod 405 located in the inner cavity of the fluid chamber 409. The fluid chamber 409 contains a non-Newtonian fluid.

[0031] in: The second component 4 is used to adjust the spacing between the forks of the mining machine to adapt to different mining stability.

[0032] The slider 403 is slidably fitted into the sliding groove 402.

[0033] The inclined block 406 slides and adapts to the inclined groove 408.

[0034] The fluid chamber 409 contains a non-Newtonian fluid. During normal forklift operation, i.e., when adjusting the distance between the outer casing 505, the non-Newtonian fluid will not affect the normal adjustment process due to the slow speed. When the forklift is engaged, the non-Newtonian fluid in the fluid chamber 409 will cooperate with the telescopic rod A407 through the perforated disc 410 to ensure the positional stability of the long rod 405.

[0035] A further embodiment: Please refer to Figure 6 , Figures 9 to 12 As shown: The third component 5 includes an electrically controlled shaft seat 501 fixedly connected to the slider 403. The electrically controlled shaft seat 501 consists of an electrically controlled shaft and a fixed seat. The fixed seat has an annular groove. An inner column 502 is arranged on the same straight line as the electrically controlled shaft. A limiting groove 503 is formed at one end of the inner column 502 near the electrically controlled shaft seat 501. The electrically controlled shaft is inserted into the limiting groove 503. A spring 504 is fixedly connected to the inner wall of the limiting groove 503. The spring 504 is located away from the limiting groove 503. 3. One end of the inner cavity wall is fixedly connected to the electric control shaft. The inner column 502 is fitted with an outer shell 505. The inner cavity of the outer shell 505 is fixedly connected with a limiting piece 506. The inner cavity wall of the outer shell 505 away from the electric control shaft seat 501 is rotatably connected to a telescopic rod B507. The telescopic shaft of the telescopic rod B507 is fixedly connected with a frustum 508 at equal intervals. Both the inner column 502 and the outer shell 505 are provided with through slots. An outward expansion piece 509 is slidably connected in the through slot.

[0036] in: The third component 5 is used for the adaptive rubbing of nuts on thin branches with low lignification, thus improving the efficiency of harvesting.

[0037] The electric control shaft seat 501 consists of an electric control shaft and a fixed seat. The fixed seat has an annular groove, and the outer casing 505 is restricted to rotate within the annular groove.

[0038] The electric control shaft of the electric control shaft seat 501 is adapted to the limiting groove 503. The inner column 502 can only move laterally with the electric control shaft of the electric control shaft seat 501 through the limiting groove 503, and cannot rotate relative to it.

[0039] The limiting groove 503 consists of a circular groove and a long strip groove.

[0040] Both spring 504 and limiting piece 506 are used to limit the position of inner column 502.

[0041] The outer casing 505 acts directly on the harvesting branches, and multiple outer casings 505 can together form a fork-and-pull system.

[0042] The working principle of all the content in the above embodiments is as follows: The following is the working process of the first component 3: During the mining process, the drive unit 304 rotates the L-shaped component 305. During this rotation, the L-shaped component 305, aided by the adjusted transverse rod 308 within it, moves the sliding block 309. Specifically, the sliding block 309 moves around the rotation axis of the drive unit 304 in a circular motion within a range of 0 to 180 degrees. The sliding block 309 slides within the inner groove of the vertical groove 303, and with the assistance of this inner groove, it can drive the vertical groove 303 and the swing arm. The movable bar 302 swings to the left around the pivot 301. As the movement continues, when the sliding block 309 moves in a circular motion between 180 and 360 degrees, the sliding block 309, with the assistance of the vertical groove 303, can drive the vertical groove 303 and the swing bar 302 to swing to the right around the pivot 301. This process repeats itself, meaning that the eccentric movement of the sliding block 309 on the L-shaped member 305 can be converted into the left-right reciprocating swing motion of the swing bar 302. This provides services for subsequent sampling. Furthermore, the swing range / amplitude of the swing bar 302 is determined by the distance of the sliding block 309 on the transverse rod 308 from the axis of the drive device 304 / shaft 301. Therefore, under different mining conditions, its off-axis can be adjusted to adapt to different working conditions. Specifically, the drive screw 307 in the straight groove 306 is activated, thereby causing the transverse rod 308, which is threadedly connected to the drive screw 307, to move in position within the straight groove 306. Please refer to the above work process. Figures 2 to 4 .

[0043] The following is the working process of the second component 4: Furthermore, when harvesting branches of different thicknesses, the spacing between the outer casing parts 505 can be adjusted via the second component 4, i.e., the spacing of the forks to be harvested; for details, please refer to the appendix. Figure 6 The position can be adjusted by controlling the extension length of the telescopic rod A407. For example, when the telescopic rod A407 extends, the inclined groove 408 on the telescopic rod A407 will cooperate with the inclined block 406 on the long column rod 405, and under its restriction, the long column rod 405 can be forced to move to the right. Since it is known that the third component 5 is fixedly connected to the slider 403, and the slider 403, the connecting column 404, and the long column rod 405 are fixedly connected to each other, when the long column rod 405 is forced to move, the slider 403 will also move laterally to the right along with the outer shell 505 set on it. Conversely, when the telescopic rod A407 shortens, the outer shell 505 will move to the left. In summary, through the above-mentioned adaptive adjustment, the spacing between adjacent outer shells 505 can be effectively controlled to adapt to different harvesting and branching requirements. Please refer to the above work process. Figure 1, Figures 5 to 8 .

[0044] The following is the working process of the third component 5: Furthermore, during the nut-harvesting process using the reciprocating outer casing 505 with the assistance of the second component 4, if thinner branches or nuts cannot be harvested, the third component 5 can be used for targeted harvesting. Specifically, first, the output shaft of the telescopic rod B507 is shortened, i.e., moved away from the electronically controlled shaft seat 501. (See attached diagram.) Figure 11 When the telescopic rod B507 is retracted, the frustum-shaped component 508 on the telescopic rod B507 moves to the left, pushing the outward expansion component 509 outward. With the outward expansion component 509 expanding, it can fit against the surface of the nut. Furthermore, activating the electric control shaft of the electric control shaft seat 501 causes the inner column component 502 to rotate with the assistance of the limiting groove 503 on the inner column component 502. Due to the outward expansion of the outward expansion component 509, the inner column component 502 and the outer shell component 505 become a single unit. That is, under the action of the electric control shaft of the electric control shaft seat 501, the inner column component 502, the outer shell component 505, and the outward expansion component 509 rotate together. At this time, the annular groove on the fixed seat of the electric control shaft seat 501 restricts and assists the rotation of the outer shell component 505. Further details can be found in the attached diagram. Figure 12 In the control, adjacent outer shell parts 505 rotate in opposite directions. At this time, the nuts located between adjacent outer shell parts 505 will be rubbed off the branches by the rotational friction of the outer expansion parts 509 on the outer shell parts 505, thus completing the nut harvesting work. This design can flexibly cope with various fruit tree varieties and branches in different growth states of the same fruit tree, expanding the applicability of the equipment and improving its practicality and versatility.
