Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, in particular to a device for quickly picking fruits without damage. Background Art

[0002] Fruit picking is the agricultural process of separating and collecting ripe fruits from fruit trees or plants.

[0003] In the agricultural production process, fruit picking is an extremely critical link. Traditional picking methods are mostly manual picking, but this method is inefficient and cannot meet the needs of large-scale orchards and fruits with short market cycles.

[0004] With the development of agricultural technology, some mechanical methods for quickly harvesting fruit have emerged, such as rapidly shaking the tree trunk to make the fruit fall. However, this method has many drawbacks. The fruit can easily break or be damaged by hitting the ground or colliding with each other during the process of falling to the ground, seriously affecting the appearance and edible value of the fruit and causing economic losses. Furthermore, the shaking of the tree trunk not only causes the fruit to fall, but also a large amount of leaves that fall off and mix with the fallen fruit, requiring further screening and sorting, reducing the efficiency of fruit picking.

[0005] Therefore, those skilled in the art are committed to developing a fruit damage-proof and fast picking device to reduce the damage caused during the fruit picking process and reduce the mixing of leaves therein. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a device for quickly picking fruits with anti-damage function, so as to reduce the damage caused during the fruit picking process and reduce the mixing of leaves therein. The technical solution of the present invention to solve the above technical problems is as follows: A fruit damage-proof quick picking device comprising An oscillating component, the oscillating component is used to drive the tree branches to shake, and an inflatable buffer component is provided at the output end of the oscillating component; The collecting component is located at the lower side of the oscillating component and has an air intake buffer component, the air intake buffer component is connected to the inflation buffer component, and the air intake buffer component also has an air outlet on the side in contact with the fruit.

[0007] The beneficial effects of adopting the above solution are: the oscillating component drives the branches to shake, so that the fruits are separated from the branches and picked quickly, which can effectively improve the picking efficiency. It is especially suitable for large-scale orchards and fruits with short market cycles. In addition, an inflatable buffer component is provided between the oscillating component and the branches to reduce damage to the branches. At the same time, the inflatable buffer component is also used to pump air into the air inlet buffer component. The collecting component can collect fallen fruits and leaves at the same time. The air inlet buffer component and the inflation buffer component are provided with air outlet holes. The gas ejected from the air outlet holes is not only conducive to blowing the leaves out of the collecting component, reducing the mixing of leaves and fruits, but also conducive to blowing air to buffer the fallen fruits, reducing the falling speed of the fruits and reducing the damage to the fruits. The inflatable cushioning component is also used to catch fallen fruits, allowing them to land softly and further reduce damage to the fruits.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the inflatable buffer component includes an inflatable airbag, which is installed at the output end of the oscillation component and connected to the air intake buffer component through an air intake pipe.

[0010] The beneficial effect of adopting the above further scheme is that the inflatable airbag makes the output end of the oscillation component contact the tree branch evenly, reducing the damage to the tree branch during the rapid vibration of the oscillation component. At the same time, the inflatable airbag is conducive to pumping air to the inflatable buffer component during the rapid vibration of the oscillation component.

[0011] Furthermore, the oscillation component includes a first oscillation arm and a second oscillation arm, the first oscillation arm and the second oscillation arm are used to clamp tree branches, the inner walls of the first oscillation arm and the second oscillation arm are installed with the inflatable airbag, the first oscillation arm and the second oscillation arm are both installed on a support arm, an adjustment component is also installed between the second oscillation arm and the support arm, and the other end of the support arm is connected to a drive component.

[0012] The beneficial effect of adopting the above further solution is: using the first oscillating arm and the second oscillating arm to clamp the branch can stably drive the branch to shake, thereby improving the picking efficiency; Inflatable air bags are installed on the inner wall of the oscillating arm to further cushion the damage to branches and fruits during the oscillation process; The adjustment component can flexibly adjust the position of the second oscillating arm according to the thickness and shape of different branches, making the device more adaptable and suitable for picking fruits from a variety of fruit trees or different diameters.

[0013] Furthermore, the adjustment assembly includes a fixed plate and an adjustment cylinder, the fixed plate is fixedly connected to the side wall of the support arm, the adjustment cylinder is installed on the fixed plate, the output end of the adjustment cylinder is connected to the second oscillation arm, and the end of the second oscillation arm is sleeved on the support arm.

[0014] The beneficial effect of adopting the above further solution is that: the fixed plate is fixedly connected to the support arm, the adjusting cylinder is installed thereon and connected to the second oscillating arm, and the second oscillating arm can be accurately adjusted to adapt to different branches.

[0015] Furthermore, the driving assembly includes a hydraulic vibrator, which is mounted on a mounting plate. An output end of the hydraulic vibrator is connected to the support arm, and a rotating assembly is also mounted on the support arm.

[0016] The beneficial effect of adopting the above further solution is that the hydraulic vibrator can provide strong and stable oscillation power for the support arm and related oscillation components, ensuring that the amplitude and frequency of the branch shaking meet the requirements for fruit shedding.

[0017] Furthermore, the support arm is hingedly connected to the hinged rod, the other end of the hinged rod is hingedly connected to the support frame, and the support frame is installed on the mounting plate.

[0018] The beneficial effect of adopting the above further solution is that the hinged rod, the support frame and the mounting plate are used to support the support arm, so that the support arm can oscillate horizontally and rapidly.

[0019] Furthermore, the air intake buffer assembly includes a receiving buffer airbag, which is installed on the deployment assembly. The deployment assembly drives the receiving buffer airbag to open into an inverted umbrella shape for receiving fallen fruits. The receiving buffer airbag is connected to the inflation buffer assembly, and the air outlet is arranged on the receiving buffer airbag.

[0020] The beneficial effect of adopting the above further solution is that the receiving buffer airbag opens into an inverted umbrella shape under the drive of the deployment component, which can effectively expand the receiving area and wrap the underside of the branch and accurately receive the fallen fruit, reducing the collision between the fruit and the ground or other hard objects.

[0021] Furthermore, the air outlet is arranged at an angle.

[0022] The beneficial effect of adopting the above further solution is that the inclined air outlet holes are not only conducive to blowing the leaves out of the receiving buffer airbag, but also used to reduce the falling speed of the fruit.

[0030] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] like Figure 1 、 Figure 2 As shown, a fruit damage-proof quick picking device includes: Oscillating assembly 1 is used to drive the tree branch to shake. An inflatable buffer assembly 2 is provided at the output end of oscillating assembly 1. When oscillating assembly 1 contacts a tree branch, inflatable buffer assembly 2 utilizes the elastic deformation of inflatable airbag 5 to absorb the impact force generated during the oscillation process, thereby preventing damage to the branch. Simultaneously, when oscillating assembly 1 vibrates rapidly, inflatable airbag 5 acts as a miniature air pump, pressurizing air into inlet buffer assembly 3 through inlet pipe 6, thereby achieving air path connectivity and air pressure regulation. The collecting component is located at the lower side of the oscillating component 1 and has an air intake buffer component 3, which is connected to the inflation buffer component 2. When air is pressed into the air intake buffer component 3, the air pressure in the air intake buffer component 3 increases, and the gas is ejected from the air outlet 4 on the side of the air intake buffer component 3 that contacts the fruit. On the one hand, the gas ejected from the air outlet 4 can blow the leaves mixed in the fruit out of the collecting component, thereby reducing the mixing ratio of the leaves and the fruit. On the other hand, the ejected gas forms an upward lifting force during the descent of the fruit, thereby slowing down the falling speed of the fruit and reducing the damage to the fruit caused by hitting the ground or other objects.

[0032] like Figure 1 、 Figure 2 As shown, in some embodiments, the inflatable airbag 5 is installed at the output end of the oscillation component 1 and is connected to the air intake buffer component 3 through the air intake pipe 6. The inflatable airbag 5 is made of flexible rubber material and has good elasticity and sealing. When the oscillation component 1 clamps the branch and starts to oscillate, the inflatable airbag 5 continues to deform with the shaking of the branch. The pressure difference generated by this deformation allows air to enter the air intake buffer component 3 through the air intake pipe 6, thereby realizing automatic transmission and pressure regulation of gas, providing power support for subsequent gas buffering and leaf blowing functions.

[0033] The oscillation assembly 1 includes a first oscillation arm 7 and a second oscillation arm 8, which are used to clamp branches. Inflatable airbags 5 are installed on the inner walls of each of the first and second oscillation arms 7 and 8. Both arms are mounted on a support arm 9. An adjustment assembly is also installed between the second oscillation arm 8 and the support arm 9. The other end of the support arm 9 is connected to a drive assembly. The adjustment assembly makes the entire oscillation device highly adaptable, allowing the position of the second oscillation arm 8 to be flexibly adjusted according to the thickness, shape, and growth posture of the branch, thereby ensuring stable clamping of the branch and laying the foundation for efficient oscillation-based fruit picking. The drive assembly provides a continuous and stable power source for the entire oscillation process, ensuring that the branch can be shaken according to the predetermined amplitude and frequency, allowing the fruit to be smoothly removed from the branch.

[0034] Specifically, the adjustment component includes a fixed plate 10 and an adjusting cylinder 11. The fixed plate 10 is fixedly connected to the side wall of the support arm 9. The adjusting cylinder 11 is installed on the fixed plate 10. The output end of the adjusting cylinder 11 is connected to the second oscillation arm 8. The end of the second oscillation arm 8 is sleeved on the support arm 9. The adjusting cylinder 11 is connected to the hydraulic station (not shown in the figure). When the position of the second oscillation arm 8 needs to be adjusted, the adjusting cylinder 11 receives the control signal, retracts and extends its output end, and drives the second oscillation arm 8 to move axially along the support arm 9. The end of the second oscillation arm 8 is sleeved on the support arm 9, so that the second oscillation arm 8 moves smoothly and accurately, and can quickly adapt to the size requirements of different branches, thereby improving the working efficiency and reliability of the picking device when facing a complex orchard environment.

[0035] The drive assembly includes a hydraulic vibrator 12 mounted on a mounting plate 16. The output end of the hydraulic vibrator 12 is connected to the support arm 9. As an efficient and powerful power output device, the hydraulic vibrator 12 converts hydraulic energy into mechanical vibration energy. When the hydraulic system supplies high-pressure liquid to the hydraulic vibrator 12, it generates regular reciprocating vibrations, which are transmitted to the first and second oscillating arms 7 and 8 via the support arm 9. This vibration, in turn, causes the branches to sway, enabling the fruit to be harvested. Also mounted on the support arm 9 is a rotation assembly 13 connected to a control assembly. In a specific embodiment, the rotation assembly 13 can be a hydraulic rotator. The rotation assembly 13 rotates the front end of the support arm 9 and the oscillating assembly 1, enabling the first and second oscillating arms 7 and 8 to grip the branches when the arms are horizontally positioned. When the arms are vertically positioned, the rotation assembly 13 rotates the front end of the support arm 9 and the oscillating assembly 1, enabling the entire harvesting device to move.

[0036] The support arm 9 is hingedly connected to the hinged rod 14, and the other end of the hinged rod 14 is hingedly connected to the support frame 15. The support frame 15 is installed on the mounting plate 16. The support arm 9 oscillates rapidly in the horizontal direction under the drive of the hydraulic vibrator 12, while the hinged rod 14 and the support frame 15 play the role of support and balance, ensuring that the support arm 9 remains stable during the oscillation process and does not swing excessively or become unbalanced.

[0037] In some embodiments, the air intake buffer assembly 3 includes a receiving buffer airbag 17, which is installed on the deployment assembly. The deployment assembly drives the receiving buffer airbag 17 to open into an inverted umbrella shape for receiving fallen fruits. When the deployment assembly receives a control instruction, the receiving buffer airbag 17 is driven by a mechanical transmission mechanism to gradually open until an inverted umbrella-shaped structure is formed, which can maximize the receiving area and collect all the fruits that fall from the lower side of the tree branches. It is like a soft "air cushion" that wraps the area under the tree branches, accurately receiving each falling fruit and preventing the fruit from colliding with the ground or other hard objects.

[0038] The receiving cushion airbag 17 is connected to the inflatable cushion assembly 2. The inflatable cushion assembly 2 not only functions at the oscillation end but also plays a key role in the air inlet cushion assembly 3. It provides sufficient air pressure support for the receiving cushion airbag 17, ensuring that the airbag has sufficient elasticity and cushioning performance. The air outlet 4 is set in the receiving cushion airbag 17. The air outlet 4 is tilted. The tilt angle is precisely calculated so that the ejected gas can form a directional airflow barrier along the trajectory of the falling fruit. This airflow barrier not only blows leaves mixed in the fruit to the outside of the receiving cushion airbag 17, causing the leaves to float away from the collection area along the direction of the airflow, but also provides a continuous upward support force for the fruit during its descent, effectively reducing the fruit's descent speed and reducing damage to the fruit caused by falling impact, greatly improving the quality of the fruit picked.

[0039] The deployment assembly includes a support rod 18, on which the receiving cushioning airbag 17 is sleeved, and the support rod 18 is installed on the rotating assembly 19. The support rod 18 serves as the skeleton support for the receiving cushioning airbag 17, ensuring the shape stability and reliability of the receiving cushioning airbag 17 during the opening and contraction process. The material is a high-strength, lightweight alloy material, which can withstand the expansion force of the receiving cushioning airbag 17 after inflation without increasing the burden on the overall device.

[0040] The rotating assembly 19 allows the support rod 18 and the receiving buffer airbag 17 a certain degree of rotational freedom. When it is necessary to pick branches at different angles, the rotating assembly 19 can be rotated and adjusted according to actual needs so that the receiving buffer airbag 17 can be accurately aligned with the bottom of the branch, thereby achieving all-round fruit collection and protection. The rotation of the rotating assembly 19 drives the support rod 18 to rotate, which is conducive to the storage or opening of the receiving buffer airbag 17. The rotating assembly 19 is installed on the base 20, and the base 20 is connected to the mounting plate 16.
