Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse transportation equipment, specifically a multi-functional transportation device for fruit and vegetable greenhouse tracks. Background Technology

[0002] As modern agriculture accelerates towards large-scale and intensive operations, greenhouses, as the core carriers of high-efficiency agriculture, are facing increasingly higher demands for production efficiency. In key stages such as fruit and vegetable harvesting and material transfer, rail transport equipment, with its significant advantages of mechanization and automation, has gradually become an indispensable auxiliary equipment in greenhouse production, improving internal logistics efficiency and greatly reducing the intensity of manual labor.

[0003] These types of rail transport equipment are mainly divided into two categories: suspended rail transport equipment and ground-based rail transport equipment. Among them, suspended rail transport equipment is widely used in fruit and vegetable greenhouses due to its unique advantages of not occupying ground space and being able to flexibly move above crops. It can cleverly avoid interference from the ground cultivation layer and is especially suitable for transporting crops that grow at high places or hanging. For example, for fruits and vegetables such as grapes and cherry tomatoes that grow in the upper part of the plant with the help of ropes or supports, the suspended track can be set up along the crop row, which not only avoids bumping the vines during transportation, but also allows the harvested fruit to be efficiently transferred directly from the picking point to the sorting area via the track, perfectly meeting the space utilization needs of intensive greenhouse planting.

[0004] However, existing technologies have the following problems in practical use;

[0005] When installing existing suspended tracks, they are directly fixed to the beams, trusses, and other components on the top of the greenhouse via brackets or booms. All load-bearing points are concentrated on the top of the greenhouse. When transporting multiple full baskets of fruits and vegetables or other heavy objects, the tracks are prone to uneven stress, which can lead to deformation and derailment. Furthermore, the existing equipment only has a transportation function and cannot be integrated with other agricultural production processes such as spraying, resulting in low equipment utilization and difficulty in meeting the multifunctional operational needs of modern agriculture. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To overcome the aforementioned shortcomings of the prior art, this utility model provides a multi-functional transport device for fruit and vegetable greenhouse tracks. This solves the problem mentioned in the background art where existing suspended tracks are directly fixed to the beams, trusses, or other components on the greenhouse roof via brackets or booms. All load-bearing points are concentrated on the greenhouse roof, making the track prone to uneven stress when transporting multiple full baskets of fruits and vegetables, leading to deformation and derailment. Furthermore, existing equipment only has transport functions and cannot be integrated with other agricultural production processes such as pesticide application, resulting in low equipment utilization and difficulty in meeting the multi-functional operational needs of modern agriculture.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional transport device for fruit and vegetable greenhouse tracks, comprising a track and a main controller. Multiple load-bearing frames are sequentially arranged from left to right at the upper end of the track. Two support columns are arranged at the lower end of the track. Two moving components are rotatably connected to the outer surface of the track. A storage shell is fixedly connected to the lower end of each of the two moving components. Multiple connecting rods are fixedly connected to the left and right sides of the storage shell. A load-bearing rod is provided at the lower end of each connecting rod. A groove is formed in the middle of the upper end of the load-bearing rod. A positive and negative threaded rod is arranged inside the groove. Two sliders are slidably connected inside the groove. One end of the positive and negative threaded rod passes through the two sliders, and the outer surface of the positive and negative threaded rod is threadedly connected to the inner wall of the slider. A driving component is provided at one end of the load-bearing rod. The output end of the driving component is detachably connected to one end of the positive and negative threaded rod. A gripper is provided at the lower end of each of the two sliders.

[0010] Preferably, a battery pack is disposed inside the storage shell, a sealing plate is disposed at the lower end of the battery pack, the upper end of the sealing plate is detachably connected to the lower end of the storage shell, and the output end of the battery pack is connected to the input end wire of the main controller.

[0011] Preferably, the two moving components are symmetrically arranged with the width center line of the storage shell as the axis of symmetry. Each moving component includes a connecting frame, and positioning plates are detachably connected to both the left and right sides of the connecting frame. Rollers are provided on the side of each of the two positioning plates near the connecting frame. A drive motor is provided on the other side of one of the positioning plates.

[0015] (III) Beneficial Effects

[0016] This utility model provides a multi-functional transport device for fruit and vegetable greenhouse tracks, which has the following beneficial effects:

[0017] This multi-functional transport device for fruit and vegetable greenhouse tracks, through the coordinated arrangement of the load-bearing frame and support columns, can segment and distribute the longitudinal load borne by the track during use, achieving uniform stress distribution. This significantly reduces stress concentration caused by concentrated loads and avoids uneven stress on the track when transporting multiple full baskets of fruits and vegetables, which can lead to track deformation and derailment. Furthermore, the coordinated arrangement of load-bearing rods, sliding grooves, positive and negative threaded rods, and grippers allows for the simultaneous clamping of multiple fruit and vegetable baskets, and the driving force generated by the drive assembly further enhances its performance. The screw drives the positive and negative threaded rods to rotate. As the screws rotate, they cause the two sliders to move in opposite directions, bringing them closer together or further apart. This controls the opening and closing of the grippers at the bottom of the sliders. Driven by the screws, the grippers move, allowing them to flexibly adapt to different sizes of fruit and vegetable baskets for precise and stable clamping. Furthermore, the grippers are not limited to fruit and vegetable transport scenarios. By adjusting the opening and closing range of the grippers, they can also clamp and fix agricultural production equipment such as pesticide spraying equipment commonly used in greenhouses, thereby improving the practicality and utilization rate of the equipment and meeting the multifunctional operation needs of modern agriculture.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Example 1;

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-functional transport device for fruit and vegetable greenhouse tracks, including a track 1 and a main controller 13. Multiple load-bearing frames 2 are arranged sequentially from left to right at the upper end of the track 1. Two support columns 3 are arranged symmetrically about the center line of the track 1's width. Each support column 3 has a pressure plate 16 at its lower end. Two moving components 4 are rotatably connected to the outer surface of the track 1. A storage shell 5 is fixedly connected to the lower end of each moving component 4. A battery pack 14 is installed inside the storage shell 5. A sealing plate 15 is installed at the lower end of the battery pack 14. The upper end of the sealing plate 15 is connected to the storage shell. The lower end of the housing 5 is detachably connected. The output end of the battery pack 14 is connected to the input end of the main controller 13. The upper end of the main controller 13 is equipped with a control button 17. The upper end of the main controller 13 is equipped with a display screen 18 near the control button 17. Multiple connecting rods 6 are fixedly connected to both sides of the housing 5. Each connecting rod 6 is equipped with a load-bearing rod 7 at its lower end. A groove 8 is opened in the middle of the upper end of the load-bearing rod 7. A positive and negative threaded rod 9 is installed inside the groove 8. Two sliders 10 are slidably connected inside the groove 8. One end of the positive and negative threaded rod 9 passes through the two sliders 10, and the outer surface of the positive and negative threaded rod 9 is threadedly connected to the inner wall of the slider 10.

[0026] Through the above technical solution, during use, the battery pack 14 can provide power to all electrical components of the device, ensuring that the device can still work when disconnected from the external power source. The sealing plate 15 can seal the battery pack 14, preventing moisture and dust from entering the storage shell 5 and protecting the battery pack 14 from damage. Simultaneously, during use, when the drive assembly 11 drives the positive and negative threaded rods 9 to rotate, the slide groove 8 can limit the movement of the slider 10 driven by the positive and negative threaded rods 9, ensuring that the slider 10 moves in a straight line and guaranteeing the clamping accuracy of the gripper 12. The connecting rod 6 connects the storage shell 5 to the load-bearing rod 7, and the load-bearing rod 7, as a carrier, accommodates the positive and negative threaded rods 9 and the slider 10 through the slide groove 8, bearing the weight of the clamped goods. The lever 6 transmits the weight of the clamped goods and the resulting pull to the moving component 4. Since the moving component 4 is connected to the track 1, the track 1 can provide support and guidance for the moving component 4, ensuring that the transport device moves stably along a fixed route, and can also bear the weight at the lower end of the moving component 4. The control button 17 set at the upper end of the main controller 13 allows the user to manually input operation commands, such as start, stop or speed adjustment. In use, the display screen 18 can display the operating status of the device, which is convenient for the user to monitor the operation of the device in real time. At the same time, the pressure plate 16 at the lower end of the support column 3 can disperse the pressure of the support column 3 on the ground, preventing the support column 3 from sinking into the soil of the greenhouse due to excessive force, and enhancing the installation stability of the device.

[0027] Please see Figure 2 and Figure 4 One end of the load-bearing rod 7 is provided with a drive assembly 11. The output end of the drive assembly 11 is detachably connected to one end of the positive and negative threaded rod 9. The lower ends of the two sliders 10 are provided with grippers 12. The drive assembly 11 includes a baffle 1101. One side of the baffle 1101 is detachably connected to one end of the load-bearing rod 7. The other side of the baffle 1101 is provided with an auxiliary motor 1102. The output end of the auxiliary motor 1102 passes through one side of the baffle 1101 and is clamped to the inner wall of one end of the positive and negative threaded rod 9.

[0028] Through the above technical solution, when it is necessary to drive the positive and negative threaded rod 9, the driving force generated by the auxiliary motor 1102 can drive the positive and negative threaded rod 9 to rotate. Due to the characteristics of the positive and negative threaded rod 9 itself, when the auxiliary motor 1102 drives the positive and negative threaded rod 9 to rotate forward, it can cause the two sliders 10 to move closer to the middle along the slide groove 8, and drive the gripper 12 to complete the tightening action. When the auxiliary motor 1102 drives the positive and negative threaded rod 9 to rotate in reverse, the sliders 10 can drive the gripper 12 to separate. At the same time, the auxiliary motor 1102 can be a geared motor with a self-locking function. After the power is cut off or the stop command is issued, the output shaft can maintain a fixed position to prevent the positive and negative threaded rod 9 from rotating in the opposite direction due to the weight of the goods. This ensures that the gripper 12 always maintains a stable clamping state during transportation. The baffle 1101 can serve as the mounting carrier of the auxiliary motor 1102 and can limit one end of the slide groove 8 to prevent the slider 10 from falling off when moving inside the slide groove 8.

[0029] Example 2;

[0030] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution based on embodiment one. Two moving components 4 are symmetrically arranged with the width center line of the storage shell 5 as the axis of symmetry. The moving component 4 includes a connecting frame 401. Positioning plates 402 are detachably connected to both the left and right sides of the connecting frame 401. Rollers 403 are provided on the side of the two positioning plates 402 near the connecting frame 401. A drive motor 404 is provided on the other side of one of the positioning plates 402. The output end of the drive motor 404 passes through one side of the positioning plate 402 and is engaged inside the roller 403. The input end of the drive motor 404 is connected to the output end wire of the main controller 13.

[0031] Through the above technical solution, during use, the power generated by the drive motor 404 can drive the roller 403 to rotate. When the roller 403 rotates, it generates driving force through friction with the surface of the track 1, which drives the storage shell 5 and the equipment at its lower end to move smoothly along the track 1. At the same time, the inner side wall of the positioning plate 402 is provided with rollers 403. The positioning plate 402 can strictly limit the axial displacement of the rollers 403, preventing the rollers 403 from swaying left and right or deviating from the track 1 during rotation. Furthermore, the spacing of the positioning plates 402 is adapted to the width of the track 1, and the limiting space formed on its inner side can wrap the track 1 between the rollers 403, further ensuring the straight-line travel accuracy of the device along the track 1. The connecting frame 401 can provide a stable installation platform for the positioning plate 402 and the rollers 403.

[0032] All electrical components mentioned in this article are connected to the external main controller 13 and 220V AC mains power through standard interfaces. The main controller 13 can be a commercially available known device. There is no special limitation on the specific models of electrical components. All can be commercially available ordinary products, as long as they can meet the usage requirements of this utility model.

[0033] In this invention, the working steps of the device are as follows:

[0034] First, the track 1 is installed inside the greenhouse using the support frame 2 and support column 3. Then, the moving component 4 is installed on the outer surface of the track 1. When it is necessary to transport fruit and vegetable baskets or agricultural machinery, a clamping command is issued through the control button 17 of the main controller 13. After the command is transmitted to the drive component 11, the auxiliary motor 1102 starts and drives the positive and negative threaded rods 9 to rotate forward inside the slide groove 8 of the load-bearing rod 7. When the goods are placed between the grippers 12, the slider 10 drives the grippers 12 to move closer to the center until the grippers 12 are in close contact with the surface of the goods, thus completing the clamping and fixing. After the goods are clamped and fixed, a transport command is issued through the control button 17 of the main controller 13. The main controller 13 transmits the signal to the drive motor of the moving component 4. The drive motor 404 starts and drives the roller 403 to rotate through the output end, thereby moving the goods held by the gripper 12. At the same time, when the device is transported to the target position by the track 1, the control button 17 of the main controller 13 issues a stop command. After the drive motor 404 stops working, the main controller 13 issues an unloading command. The main controller 13 controls the auxiliary motor 1102 of the drive assembly 11 to rotate in the opposite direction, driving the positive and negative threaded rods 9 to rotate in the opposite direction. The two sliders 10 separate to both sides along the slide groove 8, and the gripper 12 opens synchronously to release the gripped goods. After unloading, the device can be operated to return to the initial position without load by the control button 17, or continue to grip the next batch of goods for transportation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
