Description

Technical Field

[0001] This utility model relates to the field of fruit picking, and in particular to a negative pressure bionic fruit picking device. Background Technology

[0002] In orchards and the fruit picking industry chain, picking needs to be quick, gentle, and avoid damaging the fruit. Traditional picking methods (picking by hand, using scissors, mechanical grabbing, etc.) can easily cause scratches and deformation to the fruit peel, and even cause fruit cracking and damage, which in turn affects the quality and shelf life. The negative pressure bionic picker is a picking tool that combines the principle of negative pressure adsorption with a bionic flexible structure. By adsorbing the fruit, it reduces the direct squeezing and shearing of the peel and pulp, and reduces damage to the fruit surface.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Conventional bionic harvesters, when placing fruit into the collection box after harvesting, typically use a fixed position for the box, leading to potential accumulation in certain compartments, uneven fruit distribution, and increased risk of squeezing and damage. Simultaneously, the positions of the negative pressure pump and hose are also fixed, failing to adapt to different operator positions and postures, resulting in discomfort and even safety issues, ultimately leading to reduced collection efficiency and insufficient flexibility.

[0004] Therefore, those skilled in the art have provided a negative pressure bionic fruit harvester to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a negative pressure bionic fruit harvester. After the second motor is started, the collection box will begin to rotate, which helps to distribute the fruit evenly and reduces the risk of overloading in a single compartment. After the first motor is started, the position of the negative pressure air pump can be adjusted so that the hose body can adapt to different personnel positions and working distances.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fruit negative pressure bionic harvester includes a base plate. A No. 1 motor is fixedly installed on one side of the front end of the base plate. A lead screw is fixedly installed at the output end of the No. 1 motor. A movable block is threaded onto the outer end of the lead screw. A negative pressure air pump is fixedly installed on the upper end of the movable block. A telescopic tube is fixedly installed at the output end of the negative pressure air pump. A hose body is fixedly installed on the upper end of the telescopic tube. A suction cup is fixedly installed on the other side of the hose body. A hand sleeve is fixedly installed on the outer end of the hose body. A fixing plate is fixedly installed on one side of the upper end of the base plate. Multiple hose clips are fixedly installed on the upper end of the fixing plate.

[0008] An installation groove is provided on the upper side of the base plate away from the fixed plate. A second motor is fixedly installed at the front end of the installation groove. A drive gear is fixedly sleeved on the output end of the second motor. A rotating column is rotatably installed at the middle position of the inner end of the installation groove. A collection box is fixedly installed on the upper end of the rotating column. A driven gear is fixedly sleeved on the upper outer side of the rotating column.

[0009] Furthermore, the movable block is movably mounted on the upper end of the base plate, and the hose body is movably mounted on the side of the fixed plate near the movable block.

[0010] Furthermore, the handheld sleeve is connected to multiple flexible hoses via snap-fit, and the suction cup is movably positioned above the collection box.

[0011] Furthermore, the driving gear meshes with the driven gear, and the collection box is rotatably mounted above the mounting slot.

[0012] Furthermore, a battery is fixedly installed on the front side of one end of the base plate, and the No. 1 motor, the negative pressure air pump and the No. 2 motor are electrically connected to the battery.

[0013] Furthermore, a partition is fixedly installed inside the collection box, and wheels are fixedly installed at the four corners of the lower end of the base plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention proposes a negative pressure bionic fruit harvester. A negative pressure air pump uses suction cups to adsorb and quickly release fruit, enabling the harvesting of individual fruits in a short time, reducing hand operation time and improving overall harvesting efficiency. When too many fruits are piled up in a particular compartment of the collection box, a second motor drives a meshing gear mechanism to rotate the collection box, helping to evenly distribute the fruit, reducing the risk of overloading a single compartment and increasing the utilization rate of the capacity. After starting the first motor, the position of the negative pressure air pump can be adjusted, allowing the hose to adapt to different personnel positions and working distances, improving operational comfort and safety.

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

[0024] Reference Figures 1-5 One embodiment provided by this utility model:

[0025] A negative pressure bionic fruit harvester includes a base plate 1. A primary motor 3 is fixedly mounted on one side of the front end of the base plate 1. A lead screw 4 is fixedly mounted on the output end of the primary motor 3. A movable block 5 is threaded onto the outer end of the lead screw 4. A negative pressure air pump 6 is fixedly mounted on the upper end of the movable block 5. A telescopic tube 7 is fixedly mounted on the output end of the negative pressure air pump 6. A flexible hose body 8 is fixedly mounted on the upper end of the telescopic tube 7. A suction cup 10 is fixedly mounted on the other side of the flexible hose body 8. A handheld sleeve 9 is fixedly mounted on the outer end of the flexible hose body 8. A fixing plate 11 is fixedly mounted on one side of the upper end of the base plate 1. Multiple flexible hose clips 12 are fixedly mounted on the upper end of the fixing plate 11. An installation groove 14 is opened on the upper side of the base plate 1 away from the fixing plate 11. A secondary motor 16 is fixedly mounted at the front end of the installation groove 14. A handheld sleeve 9 is fixedly mounted on the output end of the secondary motor 16. There is a drive gear 17, a rotating column 13 is rotatably installed at the middle position of the inner end of the mounting groove 14, a collection box 2 is fixedly installed at the upper end of the rotating column 13, a driven gear 15 is fixedly sleeved on the upper side of the outer side of the rotating column 13, a movable block 5 is movably installed at the upper end of the base plate 1, a hose body 8 is movably installed on the side of the fixed plate 11 near the movable block 5, a hand sleeve 9 is connected to multiple hose clips 12, a suction cup 10 is movably installed above the collection box 2, the drive gear 17 is meshed with the driven gear 15, the collection box 2 is rotatably installed above the mounting groove 14, a battery is fixedly installed on the front side of one end of the upper part of the base plate 1, a first motor 3, a negative pressure air pump 6 and a second motor 16 are electrically connected to the battery, a partition is fixedly installed at the inner end of the collection box 2, and wheels are fixedly installed at the four corners of the lower end of the base plate 1.

[0026] Specifically, when picking fruit, the staff holds the hand sleeve 9 in their hand, aligns the suction cup 10 with the fruit, and then activates the negative pressure air pump 6. The negative pressure air pump 6 creates a negative pressure adsorption between the suction cup 10 and the fruit contact surface to ensure that the fruit is picked. To achieve a stable fit, the suction cup 10 mimics the flexible attachment of octopus tentacles before contact to adapt to different fruit surfaces and achieve a biomimetic picking function. At the same time, the suction cup 10 is made of flexible silicone, making the initial contact gentler and reducing the risk of fruit surface damage. After picking, the fruit is placed above the collection box 2 and the negative pressure air pump 6 is turned off, and the fruit will fall into the collection box 2.

[0027] If too much fruit is piled up in a certain compartment of collection box 2 and the storage location needs to be changed, then motor 16 is started. Since the drive gear 17 and the driven gear 15 mesh, the rotating column 13 rotates 90 degrees and moves collection box 2 to the storage location closest to the staff, so that the fruit can be loaded again.

[0028] To ensure flexibility in handling situations where workers are positioned on the left or right side of the device during actual operation, motor 3 needs to be activated to change the position of the negative pressure air pump 6, thereby adjusting the relative position of the hose body 8 and ensuring that the hose body 8 is not too far from the workers.

[0029] Meanwhile, the telescopic tube 7 has a self-elastic recovery capability, which allows the hose body 8 to be stretched a certain distance during use, thereby achieving adaptability to different fruit tree sizes. When the equipment is not in use, the hand sleeve 9 is engaged with the hose clamp 12 to prevent the hose body 8 from shifting.

[0030] Motor 3, negative pressure air pump 6, and motor 16 are all connected to the battery. The battery can provide power to motor 3, negative pressure air pump 6, and motor 16 to ensure normal operation in the orchard.

[0031] It should be noted that the suction cup 10 can only pick fruits with few or no protrusions on the surface. Fruits with too many protrusions will prevent the suction cup 10 from creating negative pressure, requiring manual removal by staff.

[0032] Working principle: When picking fruit, the worker holds the hand sleeve 9 in their hand, aligns the suction cup 10 with the fruit, and then activates the negative pressure air pump 6. The negative pressure air pump 6 creates a negative pressure adsorption between the suction cup 10 and the fruit contact surface to ensure the fruit is picked. After picking, the fruit is placed on top of the collection box 2 and the negative pressure air pump 6 is turned off, causing the fruit to fall into the collection box 2. When too much fruit is piled up in a certain compartment of the collection box 2, the second motor 16 is activated. The drive gear 17 and the driven gear 15 mesh to rotate the collection box 2. After the collection box 2 has rotated 90 degrees, the storage position of the collection box 2 can be changed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
