Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to a telescopic trolley for agricultural drones. Background Technology

[0002] Agricultural drones are intelligent aircraft used in agriculture, including multi-rotor and fixed-wing models. Through automatic control, remote sensing, and information processing technologies, they enable precise, efficient, and intelligent management of farmland operations, and have become core equipment for smart agriculture. Initially used mainly for plant protection spraying, i.e., "plant protection drones," they have now expanded to all stages of operations, including sowing and fertilization, crop monitoring, and data collection, evolving into multi-functional "agricultural drones."

[0003] Existing agricultural drone-specific equipment mostly uses trolleys. For example, Chinese utility model patent application number 202420747215.9, entitled "A Transport Trolley for Plant Protection Drones," mainly consists of a support mechanism and an extension mechanism. The support mechanism is equipped with a horizontal quick-clamp. During use, the length of the extension mechanism protruding from the support mechanism is adjusted according to the size of the drone. The lower end of the drone frame is fixed to the support mechanism by the horizontal quick-clamp. However, this design has the following disadvantages in use:

[0004] 1. Positioning the drone frame solely with horizontal quick clamps is ineffective, and the drone is prone to positional shifts during transportation.

[0005] 2. The overall load-bearing capacity of the trolley needs to be improved. When transporting drones through some bumpy sections of road, the overall structure of the trolley is prone to deformation, which will affect its subsequent use.

[0006] This utility model addresses these issues by proposing a telescopic trolley for agricultural drones. It aims to solve the aforementioned problems by providing a trolley with good positioning for drones, preventing drones from falling or shifting their position during transportation, and also by ensuring structural stability and strong load-bearing capacity.

[0012] The outer frame is provided with a limiting component, which limits the position of the movable frame within the outer frame.

[0013] As an improvement, the positioning component is located on the right side of the right positioning groove of mounting plate one and on the left side of the left positioning groove of mounting plate two.

[0014] As an improvement, the positioning component includes a vertical plate, a flip plate, and an adjusting rod. The vertical plate is connected to mounting plate one and mounting plate two. The flip plate is located above the positioning groove. The flip plate is hinged to the upper end of the vertical plate through a connecting member. The adjusting rod is located above the vertical plate. A connecting plate is provided on the lower end face of the adjusting rod. The connecting plate is hinged to the upper end of the vertical plate. The end of the adjusting rod facing the connecting member is hinged to it. A pressing part is provided on the end of the flip plate away from the connecting member.

[0015] As an improvement, the clamping part includes a limiting bolt one, a nut one, and a nut two. The limiting bolt one passes through the flip plate, and the limiting bolt one is threaded with nuts one and two. Nut one and nut two are located on the upper and lower sides of the flip plate, respectively.

[0016] As an improvement, anti-slip stripes are evenly distributed inside the positioning groove.

[0017] As an improvement, a reinforcing rod is provided on the inner side of the end of the movable frame away from the outer frame.

[0018] As an improvement, the limiting component includes a limiting seat and a second limiting bolt. The limiting seat is disposed on the upper end face of the outer frame, and the second limiting bolt is threadedly connected to the limiting seat. The lower end of the second limiting bolt is exposed inside the outer frame.

[0019] Compared to traditional technologies, the advantages of this utility model are:

[0020] 1. The positioning slot and positioning components work together to effectively position the lower end of the drone frame, preventing the agricultural drone from falling off the trolley or shifting its position during transportation.

[0021] 2. The frame consists of an outer frame and an inner frame. The inner side of the movable frame away from the outer frame is equipped with a reinforcing bar, which makes the entire frame more load-bearing and the trolley structure less prone to deformation when passing through some bumpy road sections.

[0022] 3. Adjust the length of the movable frame that is exposed above the outer frame, place the movable frame on the vehicle, and lift the outer frame to facilitate loading and transportation of the drone and trolley. Attached Figure Description

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0030] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0031] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model.

[0032] Example 1

[0033] Combined with appendix Figure 1-4 The lower ends of the outer frame 1 and the inner frame 2 are symmetrically provided with mounting plate 1 5 and mounting plate 2 6. The upper ends of the mounting plate 1 5 and the mounting plate 2 6 are provided with positioning grooves 7 on both sides of the outer frame 1. The upper ends of the mounting plate 1 5 and the mounting plate 2 6 are provided with positioning components on one side of the positioning grooves 7. The positioning components are used to fix the frame placed in the positioning grooves 7.

[0034] The positioning component includes a vertical plate 8, a flip plate 9, and an adjusting rod 10. The vertical plate 8 is connected to mounting plate 5 and mounting plate 6. The flip plate 9 is located above the positioning groove 7. The flip plate 9 is hinged to the upper end of the vertical plate 8 through a connector 11. The adjusting rod 10 is located above the vertical plate 8. A connecting plate 12 is provided on the lower end face of the adjusting rod 10. The connecting plate 12 is hinged to the upper end of the vertical plate 8. The end of the adjusting rod 10 facing the connector 11 is hinged to it. A pressing part is provided on the end of the flip plate 9 away from the connector 11.

[0035] When in use, place the agricultural drone on top of the outer frame 1. The positioning grooves 7 on the mounting plate 1 and mounting plate 2 limit the lower end of the agricultural drone frame. Hold the adjusting rod 10 and press it down. The adjusting rod 10 is hinged to the vertical plate 8 through the connecting plate 12 at the lower end. The adjusting rod 10 flips upward towards the end of the agricultural drone. The adjusting rod 10 drives the connecting piece 11, which is hinged to it and to the vertical plate 8, to flip towards the lower end of the agricultural drone frame. The connecting piece 11 drives the flipping plate 9 to flip towards the positioning groove 7, so that the flipping plate 9 is above the positioning groove 7. The flipping plate 9, together with the positioning groove 7 through the pressing part, positions the agricultural drone frame. During transportation, this prevents the agricultural drone from falling off the trolley or shifting its position.

[0036] Combined with appendix Figure 3 The clamping part includes a limiting bolt 13, a nut 14 and a nut 15. The limiting bolt 13 passes through the flip plate 9. The limiting bolt 13 is threaded with nuts 14 and nut 15. Nuts 14 and nut 15 are located on the upper and lower sides of the flip plate 9, respectively.

[0037] Rotate nut 14 and nut 25 to adjust their positions on limit bolt 13. Adjust the length of limit bolt 13 protruding from the lower end face of flip plate 9 to facilitate positioning of the lower end of agricultural drone frames of different specifications.

[0038] Combined with appendix Figure 1-2The frame includes an outer frame 1, an inner frame 2, and a movable frame 3. The outer frame 1, inner frame 2, and movable frame 3 are all U-shaped. The inner frame 2 is located inside the outer frame 1, and the opening direction of the inner frame 2 is opposite to the opening direction of the outer frame 1. The side of the inner frame 2 is connected to the inner surface of the outer frame 1, and the front end of the inner frame 2 is connected to the front end of the outer frame 1. The movable frame 3 has the same opening direction as the inner frame 2 and is slidably connected to the outer frame 1. The lower front end face of the outer frame 1 and the lower rear end face of the movable frame 3 are symmetrically provided with self-locking universal wheels 4.

[0039] The outer frame 1 is provided with a limiting component, which limits the position of the movable frame 3 within the outer frame 1;

[0040] The limiting component includes a limiting seat 18 and a limiting bolt 19. The limiting seat 18 is disposed on the upper end face of the outer frame 1, and the limiting bolt 19 is threadedly connected to the limiting seat 18. The lower end of the limiting bolt 19 is exposed inside the outer frame 1.

[0041] The frame consists of an outer frame 1 and an inner frame 2. The openings of the outer frame 1 and the inner frame 2 face each other and are connected to each other. A reinforcing rod 17 is provided on the inner side of the movable frame 3 away from the outer frame 1, which makes the entire frame more load-bearing and the trolley structure less prone to deformation when passing through some bumpy road sections. The self-locking swivel wheels 4 on the outer frame 1 and the movable frame 3 facilitate the adjustment and fixation of the trolley.

[0042] When loading, loosen the second limiting bolt 19 on the limiting seat 18 so that the second limiting bolt 19 is no longer in contact with the upper end face of the movable frame 3, and it no longer limits the position of the movable frame 3. Adjust the length of the movable frame 3 that is exposed outside the outer frame 1, place the movable frame 3 on the vehicle, lift the outer frame 1, and push the trolley into the vehicle compartment. This facilitates the loading and transportation of the drone and the trolley and can be operated by a single person.

[0043] Example 2

[0044] Combined with appendix Figure 1-2 The positioning component is located on the right side of the positioning groove 7 on the right side of the mounting plate 1 5 and on the left side of the positioning groove 7 on the left side of the mounting plate 2 6.

[0045] Based on Embodiment 1, the positioning components are located on the left and right sides of the outer frame 1, and are staggered front and back to ensure good positioning of the agricultural drone frame.

[0046] Combined with appendix Figure 4 The positioning groove 7 is uniformly provided with anti-slip stripes 16.

[0047] The anti-slip stripes 16 inside the positioning groove 7 improve the positioning effect of the positioning groove 7 on the agricultural drone frame.

[0048] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
