Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to a grape bagging support device. Background Technology

[0002] Grape bagging is a common management practice in grape cultivation, usually performed after fruit set and during the fruit enlargement stage. Bagging creates a relatively stable microenvironment for the grapes, reducing the direct impact of wind and rain on the fruit, while also lowering the probability of pest and disease infestation and preventing pesticide residues from directly adhering to the fruit surface. Furthermore, bagging can regulate the amount of light received by the fruit, helping to maintain uniform color and improving the appearance and commercial value of the grapes. It is an important auxiliary means of ensuring high-quality and high-yield grape production.

[0003] Utility model patent CN220088135U discloses an insect-proof bag for grape cultivation. This bag includes a cover with a channel glued to its upper part. An opening is formed on the front side of the cover, and a drawstring is placed inside the channel. Several ventilation holes are formed at the bottom of the cover. A waterproof intermediate layer and an adhesive outer layer are sequentially arranged outwards from the ventilation holes. The waterproof intermediate layer and the adhesive outer layer are fixed to the cover. A central hole and an external hole are formed on the waterproof intermediate layer and the adhesive outer layer, respectively. The ventilation holes, central holes, and external holes are staggered. This insect-proof bag for grape cultivation effectively improves the convenience of bagging grapes, while ensuring air exchange between the grapes and the outside environment after bagging, and also provides insect-proof, waterproof, and mildew-proof technical effects.

[0004] The pest-proof bagging used in grape cultivation requires manual handling of the bag and placing the grapes directly inside. For grapes hanging high up, operators need to frequently tiptoe, bend over, or reach into the gaps between the branches, making it difficult to accurately place the grapes into the bag. Furthermore, the operator may not be able to reach the target bunch of grapes, leading to difficulties in the bagging operation and increasing physical exertion and time consumption. In view of this, we propose a grape bagging opening aid. Utility Model Content

[0036] Please see Figures 1-5The grape bagging support device includes a main rod 100, which serves as the core support structure of the entire device, providing a stable installation foundation for other components. Its length is designed to meet the operator's needs for working with grape bunches at different heights, preventing operational difficulties caused by not being able to reach higher bunches. A grip frame 110 is fixed to the bottom of the main rod 100, providing a convenient grip for the operator and a fulcrum for pushing or pulling the pull frame 200, thus improving operational stability. The pull frame 200 is slidably connected within the grip frame 110, and the pull frame 200 can drive the pull rod 210 to move via sliding, thus transmitting... The key component for the operator's hand movements; a pull rod 210 is fixed to the top of the pull frame 200, the pull rod 210 extends into the main rod 100 and can move along the axial direction of the main rod 100. The pull rod 210 can convert the sliding motion of the pull frame 200 into linear motion along the axial direction of the main rod 100, thereby driving the movable sleeve 220 to move; an annular movable sleeve 220 is sleeved on the outer periphery of the top of the main rod 100, the movable sleeve 220 is fixedly connected to the pull rod 210 by several fixing pins 230, the movable sleeve 220 can move along the axial direction of the main rod 100 under the drive of the pull rod 210, and at the same time provide an installation position for the hinge rod 222; the main rod 10 The outer peripheral surface of the main rod 100 has a waist-shaped hole 121 for the fixed pin 230 to move. The waist-shaped hole 121 can limit the movement trajectory of the fixed pin 230, ensuring that the movable sleeve 220 moves stably along the axial direction of the main rod 100 and avoiding deviation. Several support rods 300 are hinged to the top of the main rod 100. The support rods 300 can be opened and closed by rotating at the hinge point and are the main components for opening the protective bag 400. The first end of the support rod 300 has an end rod part 310, which can provide a mounting carrier for the hook 311. At the same time, its bending structure facilitates the hook 311 to hang the protective bag 400. The tail end of the support rod 300 has a tail rod part 32. 0. The tail rod 320 can be hinged to the hinge rod 222, converting the pushing or pulling force of the hinge rod 222 into the rotational power of the support rod 300; the movable sleeve 220 is hinged to the tail rod 320 by the hinge rod 222, which can transmit the movement of the movable sleeve 220, realizing the pushing or pulling of the tail rod 320; the end of the end rod 310 is provided with a protruding hook 311, which can stably hang the mouth of the protective bag 400 to prevent the protective bag 400 from falling off during the opening or bagging process; the mouth of the protective bag 400 is hung on the protruding hook 311, and the protective bag 400 can cover the grape bunch after opening, thus playing a protective role.

[0037] like Figures 1-4As shown, in this utility model, the grip frame 110 has a rectangular frame structure, and a through cavity 111 is provided in the middle of its side surface. The cavity 111 can provide a space for the pull frame 200 and facilitate the movement of the pull frame 200 inside. Sliding grooves 112 are provided on the inner walls of the left and right sides of the cavity 111. The sliding grooves 112 can limit the sliding direction of the pull frame 200, ensuring that the pull frame 200 moves stably vertically and avoiding jamming. The pull frame 200 is fitted between the two sliding grooves 112 and can move vertically along the sliding grooves 112 within the cavity 111. A sleeve hole 120 is provided on the bottom end face of the main rod 100. The sleeve hole 120 provides space for the pull rod 210 to be accommodated and move, ensuring that the pull rod 210 can be smoothly inserted into the main rod 100. The bottom end of the sleeve hole 120 is connected to the sleeve cavity 111. This connection structure allows the pull rod 210 to be smoothly connected to the pull frame 200, ensuring the continuity of power transmission. The pull rod 210 extends into the sleeve hole 120, and the waist-shaped hole 121 is connected to the sleeve hole 120. This connection structure facilitates the connection of the fixing pin 230 to the pull rod 210 after passing through the waist-shaped hole 121. The number of waist-shaped holes 121 and fixing pins 230 are equal. The fixing pins 230 are inserted radially into the pull rod 210 after passing through the movable sleeve 220. The equal number of fixing pins ensures that the movable sleeve 220 is evenly stressed, ensuring that the movable sleeve 220 moves smoothly along the axial direction of the main rod 100, and avoiding tilting or jamming of the movable sleeve 220 due to uneven stress.

[0038] like Figures 1-3 As shown, specifically, the top end of the main rod 100 is provided with several hinge slots 130. The hinge slots 130 can provide a hinged installation position for the tail rod 320, ensuring that the tail rod 320 can rotate stably. The end of the tail rod 320 is hinged in the hinge slots 130. This hinge method allows the tail rod 320 to rotate flexibly, providing a guarantee for the opening and closing of the support rod 300. The outer circumferential surface of the movable sleeve 220 is provided with several protrusions 221, which can provide hinge points for the first end of the hinge rod 222, ensuring a stable connection between the hinge rod 222 and the movable sleeve 220; the outer surface of the tail rod 320 is provided with a hinge seat 321, which can provide hinge points for the tail end of the hinge rod 222, ensuring a stable connection between the hinge rod 222 and the tail rod 320; the first and last ends of the hinge rod 222 are hinged to the protrusions 221 and the hinge seat 321 respectively. This hinge structure can realize flexible rotation between the hinge rod 222 and the movable sleeve 220 and the tail rod 320, ensuring smooth power transmission.

[0039] like Figure 1 and Figure 5As shown, when the support rod 300 is not extended, it has a vertical rod structure, which facilitates storage when not in operation and reduces space occupation. The end rod 310 has a bent horizontal rod structure, and the protrusion 311 is located at the end of the end rod 310 near the side surface of the support rod 300, so that the protrusion 311 faces outward, which is convenient for attaching the protective bag 400. The tail rod 320 has an inclined rod structure, which facilitates cooperation with the hinge rod 222, so that the hinge rod 222 can push or pull the tail rod 320 more efficiently, thereby driving the support rod 300 to rotate.

[0040] Furthermore, when the pull frame 200 is pushed upward along the axial direction of the main rod 100, the pull frame 200 pushes the movable sleeve 220 upward along the main rod 100 via the pull rod 210 and the fixing pin 230. At this time, the movable sleeve 220 pushes the tail rod 320 upward via the hinge rod 222, causing several end rods 310 to converge with each other. This convergence action can reduce the distance between the end rods 310, making it easier for the operator to smoothly put the opening of the protective bag 400 onto the protrusion 311 between several support rods 300, reducing the difficulty of installing the protective bag 400; so that the operator can put the protective bag between several support rods 300. When the pull frame 200 is pulled downward along the axial direction of the main rod 100, the pull frame 200 pulls the movable sleeve 220 downward along the main rod 100 through the pull rod 210 and the fixing pin 230. At this time, the movable sleeve 220 pulls the tail rod 320 downward through the hinge rod 222, causing several end rods 310 to move away from each other. This moving away action can increase the distance between the end rods 310, thereby opening the mouth of the protective bag 400 hanging on the protrusion 311, preparing for the subsequent covering of the grape bunches, and ensuring that the protective bag 400 can smoothly wrap the grape bunches; thus opening the mouth of the protective bag 400.

[0041] like Figure 2 As shown, it is worth noting that the top of the protective bag 400 is provided with an elastic opening 410. The elastic opening 410 is in a contracted state when no external force is applied. The contracted elastic opening 410 can automatically fit the ear stalk after the protective bag 400 covers the ear, reducing the possibility of external pests and rainwater entering the interior of the protective bag 400 and improving the protective effect.

[0042] like Figures 1-3As shown, it is worth noting that a fixed sleeve 140 is fixed to the outer circumferential surface of the main rod 100. The fixed sleeve 140 is located below the movable sleeve 220. The fixed sleeve 140 can provide bottom support for the spring 141 and limit the lower end position of the spring 141. The spring 141 is sleeved on the outer periphery of the main rod 100 between the fixed sleeve 140 and the movable sleeve 220. The spring 141 is in a compressed state. The compressed spring 141 can generate an upward elastic force on the movable sleeve 220. When the operator releases the pull frame 200, the spring 141 can push the movable sleeve 220 to return to its original position, thereby causing the support rod 300 to automatically converge. There is no need for the operator to manually push the pull frame 200 to return to its original position, which simplifies the operation steps.

[0043] It should be added that the number of hinge grooves 130, protrusions 221, hinge rods 222, and support rods 300 are equal and their positions correspond one-to-one. This one-to-one correspondence design ensures that each support rod 300 can obtain power through the corresponding hinge rod 222, so that the rotation amplitude of all support rods 300 is consistent. This ensures that the opening of the protective bag 400 is evenly opened, avoiding uneven opening of the protective bag 400 due to insufficient rotation of some support rods 300, which would affect the bagging effect.

[0044] In this embodiment, the grape bagging support device is used as follows: First, the operator holds the holding frame 110 and pushes the pull frame 200 upward along the main rod 100 axis. The pull frame 200 drives the pull rod 210 upward. The pull rod 210 pushes the movable sleeve 220 upward along the main rod 100 via the fixing pin 230. The movable sleeve 220 pushes the tail rod 320 via the hinge rod 222, causing several end rods 310 to converge. Then, the opening of the protective bag 400 is hooked between the protrusions 311 of the multiple end rods 310 to ensure the protective bag 400 is stably fixed. Next, the operator holds the main rod 100 and moves the support rod 300 with the protective bag 400 to the target grape bunch. Position the grape bunches below the protective bag 400. Finally, pull the pull frame 200 downwards along the axis of the main rod 100. The pull frame 200 moves the pull rod 210 downwards. The pull rod 210 pulls the movable sleeve 220 downwards along the main rod 100 via the fixing pin 230. The movable sleeve 220 pulls the tail rod 320 via the hinge rod 222, causing the several end rods 310 to move away from each other, opening the mouth of the protective bag 400 and covering the grape bunches. Then, release the pull frame 200. The spring 141 pushes the movable sleeve 220 back to its original position, and the support rods 300 converge. At this point, continue to lift the main rod 100 upwards so that the mouth of the protective bag 400 detaches from the hook 311 while still holding the grapes, completing the bagging operation.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
