Abstract
Description
Technical Field
[0001] This utility model relates to the field of citrus bagging technology, specifically to an automatic bagging device. Background Technology
[0002] In citrus cultivation, farmers typically use bagging to protect the growing citrus fruits, improving yield and quality. Bagging is usually applied during the citrus's growth period. Simply put, citrus bagging acts as a protective layer, like a coat or film. Without affecting or damaging the normal growth and ripening of the citrus, bagging not only isolates the fruit from pesticides and environmental pollution, ensuring it is pollution-free, but also isolates it from pests, diseases, and dust, resulting in a smoother, brighter surface and improved quality. This leads to significant economic benefits. In the citrus industry of Southwest China, the unique climate conditions place stringent demands on citrus growth and management. In summer, some areas... Temperatures often exceed 35℃, and intense sunlight and high temperatures can easily trigger citrus sunburn, causing scorching of the fruit peel and a decline in quality. When cold waves strike in winter, local temperatures can drop below 0℃, seriously threatening the safety of citrus trees and fruits, causing frost damage or even yield reduction and crop failure. To cope with extreme weather, bagging growing citrus has become a key measure to ensure fruit quality and yield. Bagging can not only block direct sunlight and reduce the surface temperature of the fruit in summer, but also form a local insulation layer in winter to reduce heat loss and create a relatively stable microenvironment for citrus growth. Generally, the citrus bags used for bagging are mostly composite paper fruit bags, which have effective waterproof, insect-proof, sun-proof and frost-proof effects.
[0003] However, manual bagging is still the mainstream method for citrus bagging in Southwest China. In practice, bagging citrus trees at high altitudes presents many challenges. Since citrus trees can grow to a height of 3-6 meters, and the fruits at higher altitudes are scattered and irregular, workers need to frequently climb to dangerous heights using ladders, ropes, and other tools. They also often have to change climbing points multiple times due to the scattered location of the fruits. This not only places extremely high demands on the workers' physical strength and operational skills but also poses safety hazards such as falls and injuries. At the same time, frequent climbing and moving lead to low bagging efficiency.
[0004] For example, Chinese Patent CN117223527A discloses a citrus planting bagging device, which includes a device cylinder, an unfolding mechanism, a sealing mechanism, and a releasing mechanism. The bottom end of the device cylinder is fixedly connected to a fixing tube. The unfolding mechanism includes two sets of suction cups installed inside the device cylinder. The unfolding mechanism is used to attract and pull open the two sides of the paper bag, so that the paper bag opening is opened. The sealing mechanism includes a first fixing clamp and a second fixing clamp installed inside the device cylinder. The device cylinder is provided with a winding member for driving the first fixing clamp and the second fixing clamp to rotate in opposite directions for winding. The sealing mechanism is used to clamp the edge of the paper bag and the top of the metal wire tie through the first fixing clamp and the second fixing clamp, and the winding member makes the upper edge of the paper bag and the metal wire tie rotate simultaneously and wrap around the citrus branch to complete the sealing operation. The releasing mechanism is installed inside the device cylinder and is used to trigger the suction of the suction cups after the metal wire tie is completely wrapped, which facilitates the improvement of the efficiency of bagging citrus at high positions and completes the winding and sealing operation. The above patent can corroborate the defects of the prior art.
[0005] Based on this, the present invention designs an automatic bagging device to solve the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] In some embodiments, please refer to the accompanying drawings. Figures 1-4 An automatic bagging device includes a support rod 1 with a length of 3-5 meters. A support base 2 is fixedly connected to the top of the support rod 1. A bagging box 3 is fixedly connected to the top of the support base 2. A bag feeding assembly and a sealing assembly are installed on the inner wall of the bagging box 3. A symmetrical first electric telescopic rod 10 is fixedly connected to the top opening of the inner wall of the bagging box 3. A suction cup 11 for opening the bag is fixedly connected to the telescopic end of the first electric telescopic rod 10.
[0026] The bag delivery assembly is installed on the bottom inner wall of the bag box 3 and is used for delivering the bag.
[0027] The sealing assembly is installed on the inner wall of the top opening of the bag box 3 and is used to close the bag opening.
[0028] In some embodiments, such as Figures 2-4As shown in a preferred embodiment of this utility model, a spring telescopic rod 4 is fixedly connected to the inner wall of the bag box 3. A limiting plate 5 is fixedly connected to the telescopic end of the spring telescopic rod 4. Symmetrical limiting strips 6 are fixedly connected to the inner wall of the bag box 3. The side wall of the limiting plate 5 is abutted against the same side wall of the two limiting strips 6. The limiting plate 5 is a combination structure of telescopic rod and spring in the prior art. A spring is fixed to the inner wall of the telescopic rod sleeve. The other end of the spring is fixed to the end of the rod body. The other end of the rod body is fixed to the surface of the limiting plate 5. The side of the two limiting strips 6 facing the limiting plate 5 is shaped with the limiting plate 5. The two limiting strips 6 are L-shaped on the side facing the limiting plate 5, which makes it convenient to place the bag at the corner of the limiting strip 6 and hold it in place with the limiting plate 5. When one bag is pulled out, the spring of the limiting plate 5 pushes out the next bag between the two limiting strips 6. When in use, the staff places the unopened bags in a stacked state between the limiting plate 5 and the two limiting strips 6. The rod of the spring telescopic rod 4 compresses the spring inward. When a bag is conveyed upward, the spring returns to a point, so that the limiting plate 5 always presses the stacked bags between the limiting strips 6.
[0029] In some embodiments, such as Figures 2-3 As shown, in a preferred embodiment of this utility model, the bag feeding assembly includes a rubber roller 8. Two sets of symmetrical bearings 7 are fixedly connected to the surface of the bag box 3. A rotating shaft 71 is fixedly connected between the inner walls of each set of bearings 7. A rubber roller 8 is fixedly connected to the outer surface of the rotating shaft 71, and the rubber roller 8 is located near the top of the limiting strip 6. A motor 9 is fixedly connected to the outer surface of the bag box 3, and the output end of the motor 9 is fixedly connected to one of the rotating shafts 71. The length of the rubber roller 8 does not exceed the distance between the two limiting strips 6, and the surface of the rubber roller 8 is located in the gap between the two limiting strips 6. When a bag is placed between the limiting strips 6, the motor 9 is driven, and the rotation of the rubber roller 8 moves the bag upward. A pulley 72 is fixedly connected to one end of the rotating shaft 71, and a belt 73 is connected between two adjacent pulleys 72. The arrangement of two rubber rollers 8 can improve the stability when the bag moves upward.
[0030] In some embodiments, such as Figures 1-4As shown, in a preferred embodiment of this utility model, the sealing assembly includes heating rods 13. Symmetrical heating rods 13 are connected to the top opening of the inner wall of the bag box 3. Symmetrical second electric telescopic rods 12 are fixedly connected to the inner wall of the bag box 3, and the second electric telescopic rods 12 are located above the first electric telescopic rods 10. The telescopic end of the second electric telescopic rod 12 is fixedly connected to the side wall of the heating rods 13. There are four first electric telescopic rods 10, distributed in pairs on the inner wall of the bag box 3, used to move the two heating rods 13 closer together and further apart. A U-shaped isolation frame 14 is fixedly connected to the center of the surface of the heating rod 13. This isolation frame 14 keeps the two heating rods 13 away from the citrus branches when they are close together, preventing damage to the branches. Since the citrus is bagged under conditions of winter insulation and summer sun protection, the seal may not be completely airtight. The isolation frame 14 does not affect the overall bagging process. The heating plate used in the heating rod 13 is an HTF-1206 ceramic heating rod, suitable for heat pressing composite paper fruit bags. Its dimensions are 6mm in diameter × 80mm in length. The time from startup to reaching operating temperature is ≤5 seconds. When in use, the device is equipped with a 60W power rating and can rapidly heat to 120℃, meeting the hot-pressing requirements of the wax layer / PE coating on composite paper fruit bags. The inner wall of the bagging box 3 has symmetrical sliding grooves 18. A slider 17, fixed to the end of the heating rod 13 away from the isolation frame 14, is slidably connected to the inner wall of the sliding grooves 18. A support block 15 is fixedly connected to the end of the isolation frame 14 near the heating rod 13. A partition is fixedly connected to the side wall of the support block 15. The heat block 16, and the other side wall of the heat insulation block 16 are fixedly connected to the surface of the heating rod 13. This optimized structure can prevent the heat from the heating rod 13 from being transferred to the surface of the isolation frame 14, thus affecting the heat insulation effect of the isolation frame 14 on the branches. The support block 15 is made of MC901 modified cast nylon. The long-term operating temperature range of the support block 15 is -40℃ to 100℃, and it has the effect of short-term high temperature resistance of 120℃ without softening. In addition, the heat insulation block 16 is made of aerogel felt with a thickness of 2-3mm, which has the effect of withstanding 1200℃ without burning.
[0031] The bagging method mentioned in this technical solution is a composite paper fruit bag. The motor 9 is a 37GB330 model, with a power of 24W, a speed of 100-300r / min, and a DC geared motor with a shaft diameter of φ5mm. The bearing 7 is a 608 model, a deep groove ball bearing with an inner diameter of 8mm and an outer diameter of 22mm. The rotating shaft 71 can be made of 45# steel with a diameter of φ12-φ16mm, and its length is slightly larger than the spacing of the limit strips 6, ensuring that the rubber roller 8 covers the bagging conveying area. The pulley 72 is an HTD5M series synchronous pulley with 20-30T teeth and an inner diameter of φ5mm, used to cooperate with the belt 73. The model must match the output shaft diameter of the motor 9. The length of the rubber roller 8 does not exceed the spacing of the limit strips 6, and the material is nitrile rubber with a Shore hardness of 60-70A to enhance the friction with the bagging.
