Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically a handheld automatic bagging machine for young citrus fruits on branches. Background Technology

[0002] China is the world's largest producer of citrus fruits, accounting for approximately one-quarter of global citrus production annually. In citrus cultivation, bagging young fruit is a crucial step in improving fruit quality and reducing pests, diseases, and pesticide residues. Traditional manual bagging requires farmers to bag and secure each young fruit individually, resulting in low efficiency and high labor intensity. Especially in large-scale orchards, the long bagging cycle and high labor costs have become significant factors restricting the industry's profitability.

[0003] In the prior art, patents CN110915506A and CN119949178A both propose a handheld lightweight fruit bagging device, which realizes continuous bag feeding and sealing functions. However, the devices in these patents use a pinning sealing scheme, which has the problem of poor bag opening sealing and does not meet the technical requirements for citrus bagging. Patents CN221749127U and CN119866847A propose a fruit and vegetable bagging machine and a handheld automatic apple bagging machine, respectively. The methods in these patents are only suitable for sealing PE plastic bags and not for sealing paper bags of young citrus fruits. Patent CN222148453U proposes a citrus bagging device that can achieve good sealing performance between the paper bag seal and the bag opening, but this device requires manual opening of the bag and does not have a continuous bagging function.

[0004] Therefore, a new handheld automatic bagging machine for young citrus fruits on branches is needed to solve the problems of low bagging efficiency and unsatisfactory sealing effect in existing technologies. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a handheld automatic bagging machine for young citrus fruits on branches.

[0006] A handheld automatic bagging machine for young citrus fruits on branches includes a main frame, a bag storage mechanism, a bag feeding and opening mechanism, and a bag sealing mechanism, wherein the bag storage mechanism, the bag feeding and opening mechanism, and the bag sealing mechanism are all mounted on the main frame.

[0007] The main body frame is equipped with an opening button and a sealing button;

[0008] The storage bag structure includes a bag compartment located in the cavity below the main shell, forming a drawer structure, and the bag compartment is used to place fruit bags.

[0009] The sealing mechanism is vertically installed on one side of the main body frame. When the sealing button is triggered, it simultaneously drives the upper sealing clamp and the lower sealing clamp to move closer to each other, presses and seals the opening of the fruit bag opened by the feeding-opening mechanism, and automatically resets after sealing.

[0010] The bag-feeding and opening mechanism includes a translation mechanism, a lifting mechanism, an upper suction cup, and a lower suction cup. The translation mechanism is mounted on the main body frame, and the lifting mechanism is mounted on the translation mechanism. A lower suction cup is located below the lifting mechanism. The lower suction cup is located on the upper surface of the bottom plate of the main body frame, inside the bag-sealing mechanism. When the bag-opening button is triggered, the translation mechanism pushes the lifting mechanism to move horizontally, moving it to a position directly above the bag compartment. Then, it moves the upper suction cup downward, using the upper suction cup to adsorb the fruit bag inside the bag compartment. The upper suction cup then moves the lifting mechanism to the side of the bag-sealing mechanism, so that the upper suction cup is directly above the lower suction cup. Afterward, the lifting mechanism moves the upper suction cup downward, causing the fruit bag to move down and press against the lower suction cup. The lower suction cup adsorbs the lower surface of the fruit bag. The lifting mechanism then moves the upper suction cup and the upper surface of the fruit bag upward, cooperating with the lower suction cup to open the opening of the fruit bag. The bag-feeding and opening mechanism is used to control the reset of all components by the reset button.

[0011] Furthermore, the translation mechanism is an electric actuator, and the lifting mechanism includes a stepper motor, a limit rod, a guide rail, and a slider. The guide rail is fixed to the top of the main body shell by bolts; the slider is directly clamped on the guide rail and can slide freely; the stepper motor is wrapped in a stepper motor protective cover and fixed to the slider, allowing it to slide freely with the slider; the upper suction cup is connected to the suction cup base; the suction cup base is connected to one end of the stepper motor lead screw and can move up and down with the lead screw; one end of the limit rod is connected to the suction cup base and moves up and down with the base, while the other end of the limit rod passes through a limit hole on the stepper motor protective cover to prevent the lead screw from rotating due to the stepper motor; the upper air pump is fixed above the main body shell and one end is connected to the upper suction cup through an air guide pipe; the lower air pump is fixed above the main body shell and one end is connected to the lower suction cup through an air guide pipe; two electric actuators are located on the left and right sides of the main body shell respectively, with the ends of the electric actuators connected to one end of the linkage frame through connectors, and the other end of the linkage frame connected to the slider. The electric actuators are used to drive the slider to slide on the guide rail.

[0012] Furthermore, the sealing mechanism includes an upward pulling mechanism, a downward pulling mechanism, an upper sealing clamp, and a lower sealing clamp. Both the upper and lower sealing clamps are V-shaped plates with multiple strip grooves. The strip grooves of the upper and lower sealing clamps are staggered, and the two sealing clamps form a rectangle. The upward pulling mechanism and the downward pulling mechanism are used to drive the upper and lower sealing clamps closer to each other to press the opening of the fruit bag tightly.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention has a high degree of automation and can realize automated bagging of citrus fruits.

[0015] 2. This invention uses a clamping sealing method, which can achieve paper bag nesting.

The rear electric push rods A17 and B24 are connected to the linkage frame 18 via connecting blocks A16 and B25, respectively. The moving frame 18 is connected. When the two electric push rods on the left and right are working, they can drive the moving frame 18 to move. At the same time, the moving frame 18 drives the bag pressing plate 14 and the top guide rail slider 19 to move. The suction cup base 21 is equipped with the upper suction cup 22 and the lead screw of the stepper motor 9. When the stepper motor 9 is working, it will drive the suction cup base 21 and the upper suction cup 22 to move up and down through its lead screw. The upper suction cup 22 and the lower suction cup 23 are connected to the upper suction cup air pump 8 and the lower suction cup air pump 3 through the upper air guide pipe 6 and the lower air guide pipe 2, respectively. When the upper suction cup air pump 8 is started, the upper suction cup 22 can generate suction to suck up the fruit bag 37. When the upper suction cup air pump 8 and the lower suction cup air pump 3 are turned on at the same time, the fruit bag 37 can be sucked open.

[0029] like Figure 4 The diagram shows the left side of the sealing bag structure of the present invention. The diagram includes an upper sealing clamp electric push rod 26, a push rod-sealing clamp connecting sleeve 27, a fixing plate 28, an upper sealing clamp guide rail 29, an upper sealing clamp slider 30, and an upper sealing clamp 31. The left side of the upper sealing clamp 31 is connected to the upper sealing clamp electric push rod 26 via the push rod-sealing clamp connecting sleeve 27. The upper sealing clamp electric push rod 26 is fixed to the fixing plate 28. The right side of the upper sealing clamp 31 is connected to the upper sealing clamp slider 30.

When the lower sealing clamp electric push rod 32 is energized, it can drive the lower sealing clamp 33 to slide on the lower sealing clamp guide rail 36.

[0031] like Figure 4 , Figure 5 , Figure 6 As shown, when the upper sealing clamp electric push rod 26 and the lower sealing clamp electric push rod 32 work in the forward direction at the same time, the upper sealing clamp 31 and the lower sealing clamp 33 will slide relative to each other on their respective guide rails, and the reserved hole between the upper sealing clamp 31 and the lower sealing clamp 33 will shrink; as the reserved hole shrinks, the metal ring band 38 on the fruit bag 37 will be squeezed and deformed by the upper sealing clamp 31 and the lower sealing clamp 33 to achieve the purpose of sealing.

[0032] In summary, the working principle of this invention is as follows:

[0033] 1. Turn on the power and press the bag opening button on the handle. The citrus paper bag will be sent to the sealing clip and the paper bag will be opened.

[0034] 2. Align the citrus with the bag and place the citrus in it;
