[0045] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0046] In this utility model, unless otherwise stated, directional words such as "one end," "the other end," "above," "below," and "directly below" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0047] See Figure 1 The aforementioned automatic harvesting and packaging device for hydroponically grown vegetables includes a device body and a harvesting mechanism and a packaging mechanism connected to the device body. The device body includes wheels, the harvesting mechanism is used to harvest vegetables, and the packaging mechanism is used to hold and package vegetables.

[0048] The packaging mechanism includes a receiving cavity 4 and a release machine located at the bottom of the receiving cavity 4. The packaging bag 31 is placed in the receiving cavity 4. Vegetables picked by the picking mechanism are placed into the packaging bag 31. The release machine is used to release the packaging bag 31.

[0049] Through the implementation of the above technical solution, the vegetables picked by the picking organization can be placed into the packaging bag 31. After the packaging bag 31 is full, it can be released by the release machine below, thereby realizing the functions of picking and packaging vegetables. This allows the picked vegetables to be packaged on the picking site, transported faster, and is beneficial to the preservation of vegetables.

[0050] The device body includes wheels, which allow the hydroponically grown vegetable automatic harvesting and packaging device to move freely, thereby driving the harvesting mechanism to harvest vegetables within its working range. After harvesting the vegetables, the harvesting mechanism needs to place them into packaging bags 31. Therefore, both the harvesting mechanism and the packaging mechanism are connected to the device body, which fixes their relative positions. When vegetables need to be placed, the harvesting mechanism only needs to perform the corresponding action to move the vegetables it is holding to the position of the packaging bag 31. Therefore, connecting both the harvesting mechanism and the packaging mechanism to the device body facilitates the movement control of the harvesting mechanism.

[0051] Preferably, a weighing scale is provided in the receiving cavity 4 to weigh the vegetables in the packaging bag 31. By setting a minimum release weight, when the weight of the vegetables in the packaging bag 31 exceeds the set minimum release weight, the release machine is activated to release the packaging bag 31 together with the vegetables inside.

[0052] In one embodiment, the released packaging bag 31 can be picked up manually and transported to the vegetable shipping location.

[0053] In this embodiment, preferably, the harvesting mechanism includes a harvesting claw, a drive disk 22, and a harvesting arm 23 connecting the harvesting claw and the drive disk 22;

[0054] The end of the picking arm 23 is provided with a push rod 25, and the picking claw includes a first claw 211 and a second claw 212. The first claw 211 is fixedly connected to the picking arm 23, and the second claw 212 is connected to the telescopic end of the push rod 25.

[0055] The drive disk 22 can rotate, and the rotation of the drive disk 22 drives the second drive motor 24 together with the picking arm 23 to rotate in the horizontal plane, thereby adjusting the position of the picking claw in the plane.

[0056] A second drive motor 24 is installed on the drive disk 22, and the picking arm 23 is connected to the second drive motor 24. The second drive motor 24 drives the picking arm 23 to rotate in a vertical plane. By reasonably setting the positional relationship between the picking arm 23 and the packaging bag 31, the picking arm 23 can place the vegetables into the packaging bag 31 by rotating.

[0057] Through the extension and retraction of the push rod 25, the first claw 211 and the second claw 212 of the picking claw can move closer or further apart. When the first claw 211 and the second claw 212 move closer together, the picking claw can grasp the vegetables. When the first claw 211 and the second claw 212 move further apart, the picking claw can release the vegetables.

[0058] In one embodiment, when the picking claw has moved to the vicinity of the vegetable, the telescopic rod of the push rod 25 can be retracted, so that the first claw 211 and the second claw 212 move closer to each other to grasp the vegetable. Then the picking arm 23 rotates the picking claw until the picking claw moves above the receiving cavity 4. After the picking claw reaches the position to release the vegetable, the telescopic rod of the push rod 25 extends, and the first claw 211 and the second claw 212 move away from each other, and the vegetable is placed into the packaging bag 31.

[0059] In this embodiment, preferably, the packaging mechanism further includes a bag-feeding machine and a bag-stretching machine. The bag-feeding machine holds a plurality of packaging bags 31 and is located above the receiving cavity 4 to insert the packaging bags 31 into the receiving cavity 4. The bag-stretching machine is disposed on two opposite side walls of the receiving cavity 4 to stretch the packaging bags 31.

[0060] Multiple packaging bags 31 are placed inside the bag-filling machine, so that the automatic harvesting and packaging device for hydroponically grown vegetables can continuously put packaging bags 31 into the receiving cavity 4 during use, thereby ensuring the continuity of work.

[0061] The bag-opening machine located on the two opposite side walls of the receiving cavity 4 opens the packaging bag 31 by pulling the corresponding two sides of the packaging bag away from each other.

[0062] After the packaging bag 31 is opened, the vegetables picked up by the picking claw can be placed into the packaging bag 31. Then, the packaging bag 31 containing vegetables is delivered out by the release machine, which can realize the automatic picking and packaging of vegetables.

[0063] After the release machine is activated, the bag release machine can put a new packaging bag 31 into the receiving cavity 4. After the packaging bag 31 is put in, the bag opening machine opens the packaging bag 31, and the picking claw can put new vegetables into the packaging bag 31 again.

[0064] In this embodiment, preferably, the bag-feeding machine includes a bag-feeding chamber 321, a pressure bar 322 for pressing the packaging bag 31, a rotating roller 323, and a bag-feeding opening 324. The packaging bag 31 is placed in the bag-feeding chamber 321 and pressed by the pressure bar 322. The bag-feeding chamber 321 is connected to the receiving cavity 4 through the bag-feeding opening 324. The rotating roller 323 is located at the bag-feeding opening 324. The rotating roller 323 rotates and drives the packaging bag 31 to enter the receiving cavity 4 through the bag-feeding opening 324.

[0065] The pressure bar 322 cooperates with the bag release plate 325 to press the packaging bag 31. The packaging bag 31 is pressed on the bag release plate 325. The rotating roller 323 located at the bag release opening 324 can rotate. Utilizing the friction between the rotating roller 323 and the packaging bag 31, the rotating roller 323 can push the packaging bag 31 that is in contact with the rotating roller 323 to the bag release opening 324 during the rotation process. Through the continuous rotation of the rotating roller 323, the packaging bag 31 moves forward continuously until the packaging bag 31 leaves the pressure bar 322 and falls into the receiving cavity 4.

[0066] Preferably, the width of the bag opening 324 is only wide enough for one packaging bag 31 to pass through, so that the rotating roller 323 can only push one packaging bag 31 into the receiving cavity 4 at a time. The pressure bar 322 is located near the bag opening 324, so that under the action of the pressure bar 322, the pressure between the lowermost packaging bag 31 and the rotating roller 323 is large enough, so that the packaging bag 31 can move forward with the rotating roller 323, ensuring that the packaging bag 31 can reliably enter the bag opening 324. Preferably, the surface of the rotating roller 323 is set with a high coefficient of friction.

[0067] The pressure bar 322 is designed to have a certain weight, and its own weight is used to compress the packaging bag 31. The bag feeding machine is equipped with sliding grooves, and each end of the pressure bar 322 engages with two oppositely arranged sliding grooves. As the packaging bag 31 continuously enters the receiving cavity, the pressure bar 322 descends along the sliding grooves, thus reliably compressing the packaging bag 31. Preferably, at least two pressure bars 322 are provided, and multiple pressure bars 322 are arranged parallel to the bag feeding opening 324. Multiple pressure bars 322 compress multiple packaging bags 31, ensuring that the packaging bags 31 do not tilt upwards and facilitating the smooth entry of the end of the packaging strap 31 into the bag feeding opening 324.

[0068] The bag-laying plate 325 is tilted, and the tilt angle of the bag-laying plate 325 is controlled so that the packaging bag 31 can fall into the receiving cavity 4 below.

[0069] In this embodiment, preferably, the bag-sizing machine includes a suction cup 331 slidably connected to the side wall of the receiving cavity 4 and a vacuum pump connected to the suction cup 331. Multiple suction cups 331 are provided, and the multiple suction cups 331 are respectively located on two opposite side walls of the receiving cavity 4.

[0070] The vacuum pump connected to the suction cup 331 continuously extracts air from the suction cup 331. The suction cups 331 located on both sides of the receiving cavity 4 can also approach each other. After the suction cups 331 approach each other and contact both sides of the packaging bag 31, the air between the suction cups 331 and the packaging bag 31 is sucked out under the action of the vacuum pump, and the packaging bag 31 is completely attached to the suction cups 331 and can move with the suction cups 331. Subsequently, the suction cups 331 move away from each other, causing the two opposite sides of the packaging bag 31 to also move away from each other, thereby achieving the purpose of opening the packaging bag 31.

[0071] The packaging bag 31 is made of a material with a certain degree of rigidity, so that the surface of the packaging bag 31 that is being attracted by the suction cup 331 is not easily deformed. Preferably, the packaging bag 31 is a kraft paper bag.

[0072] In this embodiment, preferably, the bag-stretching machine further includes a telescopic first drive 332, which is fixedly connected to the receiving cavity 4, and the telescopic end is fixedly connected to the suction cup 331.

[0073] The suction cups 331 on both sides are connected to the telescopic ends of the first drive 332 on both sides respectively. The first drive 332 telescopically pushes the suction cups 331 on both sides closer or further apart.

[0074] In one embodiment, the first drive 332 is configured as a cylinder. Preferably, a solenoid valve 333 is provided to control the air path of the first drive 332. The solenoid valve 333 first controls the first drive 332 to extend, pushing the suction cups 331 on both sides to the position of the packaging bag 31. After the suction cups 331 adsorb both sides of the packaging bag 331, the solenoid valve 333 is activated, the first drive 332 retracts, and the two suction cups 331 retract with the first drive 332, simultaneously causing the opening of the packaging bag 31 to open.

[0075] Multiple suction cups 331 are arranged along the width of the packaging bag on the same side of the packaging bag 31. The suction cups 331 on both sides of the packaging bag 31 are arranged one-to-one to prevent the packaging bag 331 from being torn when the suction cups 331 on both sides come close to each other.

[0076] Multiple suction cups 331 located on the same side are connected by a connecting rod, enabling the multiple suction cups 331 to move synchronously. The multiple suction cups 331 are connected to the same vacuum pump, achieving synchronous vacuuming action.

[0077] In this embodiment, preferably, the release mechanism includes a second drive 341 and a connecting plate 342. One end of the connecting plate 342 is connected to the second drive 341, and the other end is connected to the bottom cover plate 41 of the receiving cavity 4. The second drive 341 drives the connecting plate 342 to rotate, thereby opening or closing the bottom cover plate 41 of the receiving cavity 4.

[0078] The second drive 341 is configured as a retractable structure, and preferably, the second drive 341 is configured as a cylinder.

[0079] The second drive 341 is fixedly connected to the receiving cavity 4. The telescopic rod of the second drive 341 is slidably connected to the connecting groove 3421 on the connecting plate 342 through the connector 3422. The connecting plate 342 is rotatably connected to the receiving cavity 4. The connecting groove 3421 is located on the upper part of the rotating shaft of the connecting plate 342. The lower part of the rotating shaft of the connecting plate 342 is fixedly connected to the bottom cover plate 41.

[0080] As the telescopic rod of the second drive 341 retracts, the connecting plate 342 rotates, and the connecting piece 3422 pulls the connecting slide 3421 to rotate toward the second drive 341. The part of the connecting plate 342 connected to the bottom cover plate 41 will rotate away from the receiving cavity 4, thereby realizing the opening of the bottom cover plate 41. The packaging bag 31 located in the receiving cavity 4 then falls onto the device body below from the opened position.

[0081] In this embodiment, preferably, the device body also includes a workbench 1 and a lifting platform 13 located above the workbench 1, the walking wheels 12 are located below the workbench 1, the packaging mechanism is located above the workbench 1, and the picking mechanism is connected to the lifting platform 13.

[0082] The walking wheels 12 can drive the workbench 1 to move within the work area. The picking mechanism is connected to the lifting platform 13. The picking claw can adjust its position in the height direction, making it easier for the picking claw to reach the position of the vegetables to be picked.

[0083] The lifting platform 13 is driven by the third drive 131 to achieve lifting. In order to ensure the stability of the lifting platform 13 during the lifting process, the lifting platform 13 is also equipped with a guide structure.

[0084] The packaging mechanism is located above the workbench 1 and is fixedly connected to the workbench 1, so that the harvested vegetables can easily enter the packaging mechanism for packaging.

[0085] By setting up the lifting platform 13, the picking mechanism can achieve more degrees of freedom in position adjustment. The lifting platform 13, together with the second drive motor 24, enables the picking arm 23 to achieve position adjustment in both the height direction and the horizontal plane. The drive disc 22 can also drive the picking arm 23 to swing within a certain angle.

[0086] In this embodiment, preferably, a conveyor plate 14 is provided on the workbench 1, which is located directly below the bottom cover plate 41 and is used to convey the packaging bag 31 released from the bottom cover plate 41.

[0087] After the bottom cover 41 is opened, the packaging bag 31 can fall onto the conveyor plate 14 below under its own weight. In one embodiment, the packaging bag 31 containing vegetables can be transferred manually. In another embodiment, the conveyor plate 14 is configured as a mechanism that can move along the upper surface of the workbench 1.

[0088] The conveyor plate 14 can be connected to the vegetable conveyor line by translation. The packaged bags 31 can be transferred to the vegetable conveyor line through the conveyor plate 14, so as to realize the fast and reliable packaging and transfer of vegetables and improve the efficiency of vegetable rotation.
