[0002] Fruit bagging is a protective measure that involves covering fruits with specially made paper or plastic bags. It can prevent insects, birds, and pathogens from infecting the fruit, reduce pesticide residues, improve fruit color, reduce fruit cracking and sunburn, and increase commercial value. It is mostly used for varieties such as apples, pears, and grapes. It needs to be done in a timely manner after physiological fruit drop, and attention should be paid to the quality of bag selection and subsequent management.

[0003] Chinese utility model patent CN222442530U discloses a winter bagging device for fruit trees. This device can be adjusted in length by means of a telescopic component, thus making it suitable for bagging operations at different heights. The bagging claws open the bag, and the operating lever, in conjunction with the opening component, ties the opened bag shut. This avoids the need for frequent tree climbing and ladder construction, allowing bagging operations to be performed directly on the ground for taller fruits. The operation is simple and convenient.

[0004] However, fruit trees have many branches, which can obstruct the position of the telescopic parts. Since the position of the bagging claw cannot be adjusted, the bagging claw cannot accurately place the bag over the obscured fruit. Utility Model Content

[0005] The purpose of this invention is to provide a fruit bagging device to solve the problem that the position of the bagging claw in the prior art cannot be adjusted, which makes it impossible for the bagging claw to accurately put the bag on the covered fruit.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please see Figures 1 to 6 A fruit bagging device includes an extended arm 11, a plurality of grippers 41 disposed at one end of the extended arm 11, and a drive unit for synchronously opening and closing the plurality of grippers 41, and further includes:

[0037] The cross shaft 2 has two pairs of coaxial journals, wherein the ends of the first pair of journals are rotatably mounted to one end of the extension arm 11;

[0038] Adjusting head 31 is rotatably mounted on the second pair of journals of cross shaft 2;

[0039] Adjustable ball 61 is fixedly installed on the outside of extended arm 11;

[0040] Several guide grooves 66 are provided on the outside of the adjusting ball 61 and are evenly distributed around the axis of the adjusting ball 61. Locking holes 65 perpendicular to the axis of the adjusting ball 61 are provided on the guide grooves 66.

[0041] A ring sleeve 62 is fitted on the outside of the adjusting ball 61. Several adjusting pins 63 are threaded onto the ring sleeve 62. One end of the adjusting pin 63 is located in the guide groove 66 and can pass into the inside of the locking hole 65.

[0042] Several adjusting ropes 64 are fixed at one end to the ring 62 and at the other end to the outside of the adjusting head 31. The adjusting ropes 64 are evenly distributed around the axis of the adjusting ball 61.

[0043] However, fruit trees have many branches, which can obstruct the position of the telescopic parts. Since the position of the bagging claw cannot be adjusted, the bagging claw cannot accurately place the bag over the obscured fruit.

[0044] The extended arm 11 is made of hollow plastic tube. Several grippers 41 are arc-shaped and evenly distributed around the axis of the adjusting head 31. The number of grippers 41 is preferably four. The end of each of the four grippers 41 away from the adjusting head 31 is protruding to open the bag opening. The driving component drives several grippers 41 to move closer to each other and put the bag on the outside of the fruit.

[0045] In the current environment, fruit trees have many branches, which can block the position of the telescopic component. The position of the bagging claw cannot be adjusted, resulting in the bagging claw being unable to accurately put the bag on the obscured fruit.

[0046] This design employs a fixedly installed adjusting ball 61 on the outer side of the extended arm 11. The adjusting ball 61 is positioned on the side of the extended arm 11 furthest from the adjusting head 31. Preferably, four guide grooves 66 are formed on the outer side of the adjusting ball 61. A ring sleeve 62 is fitted onto the outer side of the adjusting ball 61, and the ring sleeve 62 can rotate along the guide grooves 66 under the limiting position of the adjusting pins 63. Preferably, four adjusting pins 63 are formed, and the adjusting pins 63 are threadedly connected to the ring sleeve 62. Rotating the adjusting pins 63 clockwise allows the ends of the adjusting pins 63 to pass into the locking holes 65. Two opposite pins... The locking holes 65 are coaxially arranged, and the number of adjusting ropes 64 is preferably four. One end of each of the four adjusting ropes 64 is fixedly connected to the outside of the ring 62, and the connection point is located at the position corresponding to the adjusting pin 63. The other end of the adjusting rope 64 is connected to the outside of the adjusting head 31. By rotating the two coaxial adjusting pins 63, they are made to be engaged in the corresponding locking holes 65. The rotating adjusting ball 61 pulls the adjusting head 31 to shift its angle through the adjusting ropes 64, thereby adjusting the deflection angle of the gripper 41, so that the gripper 41 can bypass the obstruction of the branches and realize the bagging of the fruit.

[0047] In one embodiment of this utility model, the driving element includes:

[0048] The drive shaft 32 is slidably mounted inside the adjusting head 31. Drive grooves are evenly opened on the outer side of the drive shaft 32. The drive shaft 32 is hinged to one end of the gripper 41, and the gripper 41 is rotatably connected to the adjusting head 31.

[0049] The traction shaft 33 is fixedly mounted on one end of the drive shaft 32 near the extension arm 11;

[0050] The limiting plate 34 is sleeved on the outside of the traction shaft 33 and is fixedly connected to the inside of the adjusting head 31.

[0051] The elastic element 35 is sleeved on the outside of the traction shaft 33 and located between the limiting plate 34 and the drive shaft 32;

[0052] The traction rope 56 is fixedly installed at the end of the traction shaft 33 away from the drive shaft 32.

[0053] When the drive shaft 32 slides along the axis of the adjusting head 31, the drive grooves evenly opened on the outer side of the drive shaft 32 drive the teeth opened at the ends of the grippers 41, so that the grippers 41 open or close synchronously. The elastic element 35 is a damping spring or a spring. The two ends of the elastic element 35 abut against the limiting plate 34 and the drive shaft 32 respectively, so that the grippers 41 remain open. The traction rope 56 is used to pull the drive shaft 32 to move away from the adjusting head 31. The limiting plate 34 is fixedly installed on the inner side of the adjusting head 31. The traction rope 56 pulls the traction shaft 33 to slide along the axis of the limiting plate 34, which drives the ends of multiple grippers 41 to tighten.

[0054] In one embodiment of the present invention, the other end of the traction rope 56 is wound and connected to a turntable 55, the turntable 55 is located inside the extension arm 11, and a coaxial fixed shaft 53 is installed on the outside of the turntable 55, with both ends of the fixed shaft 53 passing through and extending to the outside of the extension arm 11.

[0055] The turntable 55 is a winding reel with a spring mechanism, which can automatically rotate around the fixed shaft 53 to wind up the traction rope 56, so that the traction rope 56 is always kept taut.

[0056] In one embodiment of this utility model, a limiting groove 12 is formed on the extended arm 11 along the length direction, and a slider 54 is slidably installed inside the limiting groove 12. The slider 54 is fixedly connected to the fixed shaft 53.

[0057] The limiting groove 12 is used to provide a moving path for the fixed shaft 53, and the slider 54 can limit the fixed shaft 53 to prevent it from rotating.

[0058] In one embodiment of the present invention, a drive rod 52 is provided at the end of the fixed shaft 53. The drive rod 52 is located outside the extension arm 11. The top of the drive rod 52 is engaged with the end of the fixed shaft 53. A fixed rod 51 is rotatably installed at the bottom of the drive rod 52. The fixed rod 51 is fixedly connected to the outside of the extension arm 11.

[0059] The drive rod 52 is mounted on the outside of the extension arm 11 via a fixed rod 51 that is rotatably connected to it. By manually pressing the drive rod 52, the fixed shaft 53 is driven to slide along the inner side of the limiting groove 12, thereby pulling the traction rope 56 to move the drive shaft 32 and causing the end of the drive gripper 41 to retract.

[0060] In one embodiment of this utility model, a fixing member 42 is fixedly installed on the side where the other ends of several grippers 41 are close to each other.

[0061] The fastener 42 is a U-shaped metal spring clip used to clamp the bag opening, allowing the bag to open.

[0062] In one embodiment of the present invention, a shoulder support 13 is rotatably mounted on the end of the extended arm 11 away from the adjusting head 31.

[0063] Shoulder support 13 is used for shoulder support, increasing the convenience of use. Shoulder support 13 can rotate and provide support for fruits in different positions.

[0064] Working principle: In use, the worker first rests the shoulder support 13 on their shoulder to stabilize the extended arm 11, and holds the extended arm 11 to align the gripper 41 with the fruit. If the branch obstructs the fruit, the worker rotates the adjusting pin 63 clockwise so that its end passes through the locking hole 65 to lock the ring 62. Then, the adjusting ball 61 pulls the adjusting head 31 around the cross shaft 2 through the adjusting rope 64, thereby adjusting the angle of the gripper 41 to bypass the branch. Next, the worker presses the drive rod 52, which drives the fixed shaft 53 along the limit. When groove 12 slides, fixed shaft 53 drives turntable 55 to release traction rope 56. Traction rope 56 pulls traction shaft 33, causing drive shaft 32 to slide within adjusting head 31 and compress elastic element 35. Drive shaft 32 drives gripper 41 to retract synchronously through drive groove. Fixing element 42 on gripper 41 opens bag opening and puts bag on fruit. After releasing drive rod 52, elastic element 35 pushes drive shaft 32 to reset, gripper 41 opens, and turntable 55 automatically winds traction rope 56 to restore system to initial state.

[0065] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
