Abstract
Description
Technical Field
[0001] This utility model relates to the field of harvesting device technology, specifically a fruit planting and harvesting device. Background Technology
[0002] Fruit picking devices are tools that can pick fruit. There are large fruit picking machines and small fruit picking devices. Fruit picking devices can be used by a single person. They are tools that can automatically pick fruit from trees at a low position without climbing and are easy to operate.
[0003] Existing fruit-harvesting equipment is ill-suited to the height of fruit trees, making it difficult to flexibly adapt to the harvesting needs of fruits at different heights. Furthermore, harvested fruit often suffers abrasions and damage to the flesh from falling directly to the ground, affecting fruit quality and commercial value. In addition, when cutting fruit at the base, the branches are prone to swaying under stress. This swaying not only prevents the fruit from being completely severed from the branch, increasing the difficulty and cost of secondary harvesting, but also may cause unripe or under-harvested fruit to fall, resulting in unnecessary economic losses. Moreover, the frequent secondary processing increases the burden on manual labor, leading to low overall harvesting efficiency and inconsistent fruit quality. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention utilizes a coordinated mechanism of a mobile collection mechanism, a telescopic guide mechanism, a lifting drive mechanism, and a picking mechanism to guide and collect fruits at different heights during harvesting.

[0019] Please see Figure 1-4 A fruit planting and harvesting device includes a mobile collection mechanism 3, a telescopic guide mechanism 2 connected to the upper side of the mobile collection mechanism 3, a lifting drive mechanism 1 arranged on the upper side of the mobile collection mechanism 3 and spaced apart from the telescopic guide mechanism 2, and a harvesting mechanism 4 arranged on the upper side of the telescopic guide mechanism 2. The lifting drive mechanism 1 is connected to the telescopic guide mechanism 2. The harvesting mechanism 4 includes two symmetrically arranged clamping and fixing mechanisms, an installation shell 8 arranged on the upper side of the clamping and fixing mechanisms, and a branch fixing mechanism and a cutting mechanism arranged on one side inside the installation shell 8 and spaced apart from top to bottom. The open ends of the two installation shells 8 are arranged opposite each other, the two branch fixing mechanisms are arranged symmetrically, and the two cutting mechanisms are arranged in a staggered manner.
[0020] The branch fixing mechanism includes a first electric push rod 9 installed inside one side of the mounting housing 8, a connecting plate 10 connected to the output shaft of the first electric push rod 9, two connecting posts 11 horizontally spaced and connected to one side of the connecting plate 10, and a columnar clamp 12 vertically arranged and connected to one end of the connecting posts 11. The outer wall of the columnar clamp 12 is provided with a rubber pad; the power output of the first electric push rod 9 controls the connecting plate 10 to drive the connecting posts 11 and the columnar clamp 12 to move synchronously, thereby clamping the branch.
[0021] The cutting mechanism includes a second electric push rod 13 located inside the mounting housing 8 and below the first electric push rod 9, and a cutting blade 14 connected to the output shaft of the second electric push rod 13.
[0022] The clamping and fixing mechanism includes a fixed vertical plate 5, an airbag 7 connected to the inner side of the fixed vertical plate 5, an air pipe 28 connected to the airbag 7 and equipped with a solenoid valve on the pipe section, and an air pump 6 connected to one end of the air pipe 28 and located on the other side of the fixed vertical plate 5. The fixed vertical plate 5 is connected to the lower side of the mounting shell 8. The clamping and fixing mechanism exhibits unique and practical advantages through the coordinated operation of the air pump 6, the air pipe 28, and the airbag 7. The air pump 6 inflates the airbag 7 through the air pipe 28, which can adaptively wrap and clamp fruits of different shapes and sizes. Compared with traditional rigid clamping components, it avoids the problem of fruit skin damage or pulp crushing caused by improper clamping force. After deflating, the airbag 7 returns to its original shape, making it easy for the fruit to detach and enabling rapid harvesting.
[0023] The telescopic guide mechanism 2 includes a collecting hopper 15, an opening 16 on the upper side of the collecting hopper 15, a first fixed pipe 17 communicating with the lower side of the collecting hopper 15, a corrugated pipe 18 communicating with one end of the first fixed pipe 17, and a second fixed pipe 19 communicating with one end of the corrugated pipe 18. The lower side of the fixed vertical plate 5 is connected to the upper side of the collecting hopper 15, and the opening 16 is located between the two fixed vertical plates 5. An air pump 6 is connected to the upper side of the collecting hopper 15. The opening 16 and the collecting hopper 15 can catch the fruit falling after picking. The opening 16 is located between the two fixed vertical plates 5 to ensure that the fruit can enter the collecting channel after picking. The corrugated pipe 18 has good telescopicity and can be flexibly deformed according to the height adjustment of the lifting drive mechanism to ensure that the fruit conveying channel is unobstructed and to avoid interruption of fruit conveying due to changes in the height of the device.
[0024] The lifting drive mechanism 1 includes a mounting plate 27, an electric slide rail 20 mounted on one side of the mounting plate 27, a slider 21 slidably connected to the electric slide rail 20, and an L-shaped bracket 22 connected to one side of the slider 21. The horizontal section of the L-shaped bracket 22 is connected to the first fixed pipe 17. Through the linkage of the electric slide rail 20, the slider 21, and the L-shaped bracket 22, the height of the harvesting mechanism can be adjusted, allowing it to adapt to fruit trees of different heights. This eliminates the need for frequent manual adjustments to the device position or the use of other auxiliary tools, improving the convenience and efficiency of the harvesting operation.
[0025] The mobile collection mechanism 3 includes a collection box 23, four connecting rods 24 arranged in a rectangular array on one side of the collection box 23, a vertical plate 25 connected to one end of the four connecting rods 24, and two handles 26 horizontally spaced and connected to one side of the vertical plate 25. One end of the second fixing pipe 19 is connected to the upper side of the collection box 23. The collection box 23 is used to centrally collect the harvested fruit, improving the continuity and efficiency of the harvesting operation. The second fixing pipe 19, connected to the upper side of the collection box 23, can guide the fruit transmitted by the telescopic guide mechanism into the collection box 23, forming a complete fruit collection and transmission path, ensuring that the harvested fruit can complete the collection process and preventing the fruit from falling or being damaged during transmission. The four corners of the lower side of the collection box 23 are equipped with casters.
[0026] A PLC controller is installed on one side of the upright plate 25 for centralized control of the first electric push rod 9, the second electric push rod 13, the two air pumps 6, the electric slide rail 20, and the solenoid valve. The PLC controller is electrically connected to all of the above components.
[0027] Working Process and Principle: When using this fruit picking device, the operator holds both handles 26 and pushes the collection box 23 to move within the orchard. Upon reaching the target picking position, the electric slide rail 20 is activated via the PLC controller according to the height of the fruit tree. At this time, the slider 21 slides along the electric slide rail 20, driving the L-shaped bracket 22 to move vertically up and down; the L-shaped bracket 22 then pulls the first fixed pipe 17 to move synchronously, and the corrugated pipe 18 extends and retracts accordingly, realizing the height adjustment of the picking mechanism 4 to ensure that it maintains a suitable position with the fruit to be picked. Subsequently, the collection box 23 is moved again to place the fruit to be picked between the two airbags 7. The PLC controller controls the air pump 6 and the solenoid valve on the air pipe 28 to start synchronously, inflating the airbags 7. The airbags 7 hold the fruit in a flexible wrapping manner, avoiding damage to the fruit skin caused by traditional rigid clamping. After the fruit is secured, the first electric push rod 9 is activated, causing the connecting plate 10 to move towards each other. The four connecting columns 11 then drive the cylindrical clamps 12 to tighten synchronously, securing the branch from both sides and providing stable support for subsequent cutting. Next, the second electric push rod 13, controlled by the PLC controller, begins operation, driving two staggered cutting blades 14 to move relative to each other, cutting the fruit's base. Thanks to the branch-fixing mechanism, the cutting process avoids cutting deviations caused by branch swaying or other fruit falling from the branch. After cutting, the PLC controller restarts the air pump 6 to deflate the airbag 7, releasing the clamps. The cut fruit then falls through the opening 16 into the collection hopper 15, and then through the first fixing pipe 17, the corrugated pipe 18, and the second fixing pipe 19, finally falling into the collection box 23.
[0028] In summary, this device can adjust the picking position according to the height of the fruit, realizing automated picking and guiding the fruit through the collection process. In addition, the branch fixing mechanism can fix the branches before picking, providing stable support for the cutting operation. This not only avoids cutting deviations caused by branch shaking, but also prevents other fruits from falling off or being damaged, ensuring that the fruit is picked intact, reducing secondary processing, reducing the difficulty of manual operation, and improving the overall picking efficiency and fruit quality.
[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
