Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle feeding devices, and in particular relates to a catapult-type feeding device for unmanned aerial vehicles. Background Art

[0002] Most of the existing drone feeding devices use the material's own weight to feed after the safety or lock is opened. The material thrown in this way descends slowly and is greatly affected by the airflow, which can easily cause a large deviation between the landing point and the predetermined delivery position. In addition, the existing feeding device also has the problem of material jamming, which makes it impossible to throw the material smoothly. Utility Model Content

[0003] In order to solve the shortcomings of the existing technology, the utility model provides a UAV catapult feeding device, which can speed up the material throwing speed, reduce the influence of airflow on the feeding accuracy, and effectively improve the material feeding position accuracy.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A UAV catapult feeding device comprises: a barrel-shaped silo, the top of which is used to connect to the bottom of the UAV, the lower end of the silo is open, and the upper end of the interior of the silo is provided with an elastic member, whose telescopic direction is consistent with the axial direction of the silo.

[0006] The lower section of the silo is provided with a plurality of chutes in a circular array, and the chutes are all parallel to the axis of the silo; the outer wall of the silo is provided with limit plates in pairs on both sides corresponding to the chutes; there is a gap between the limit plates in pairs, and the opposite side walls are provided with limit grooves parallel to the chutes; the top of the chutes is higher than the top of the limit plates by a predetermined distance.

[0007] A locking block is penetrated through the slide groove and is movable along the length direction of the slide groove. The front end top of the locking block has an inclined surface, and the rear end of the locking block is provided with a connecting plate. The two sides of the connecting plate protrude from the two sides of the locking block and are used to connect the paired limit grooves. When the two sides of the connecting plate slide in the limit grooves on both sides, the inclined surface is located inside the silo, and the overall height of the locking block is less than the predetermined distance between the top of the slide groove and the top of the limit plate.

[0008] The rear end face of the connecting plate is provided with at least one guide rod, which is perpendicular to the axis of the silo. The outer sleeve of the silo is provided with a driving ring. The silo is provided with a driving device for driving the driving ring to move along the axis of the silo. The guide rods are all passed through the driving ring, and the locking block is movably arranged along the axis of the guide rod.

[0009] The beneficial effects of the utility model are as follows: when feeding, the locking block is used to push the material and compress the elastic member. When the locking block moves to a predetermined position, the locking block will automatically move away from under the material, and the material will be quickly ejected under the elastic force of the elastic member, thereby accelerating the ejection speed of the material, thereby reducing the influence of the airflow on the material feeding trajectory and improving the feeding position accuracy; in the non-feeding stage, the elastic member is in a naturally stretched state, avoiding long-term compression that causes the elastic force of the elastic member to decrease, and preventing the material from being ejected or damaged due to accidental touch when the material is stored under pressure.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0017] like Figures 1 to 4 As shown, a UAV catapult feeding device includes: a barrel-shaped silo 1, the top of which is used to connect to the bottom of the UAV, the lower end of the silo 1 is open, and the upper end of the interior of the silo 1 is provided with an elastic member 2, and its telescopic direction is consistent with the axial direction of the silo 1.

[0018] The lower section of the silo 1 is provided with a plurality of chutes 11 along a circumferential array, and the chutes 11 are all parallel to the axis of the silo 1; the outer wall of the silo 1 is provided with a pair of limit plates 3 on both sides corresponding to the chutes 11; there is a gap between the limit plates 3 arranged in pairs, and the opposite side walls are provided with limit grooves 31 parallel to the chutes 11; the top of the chutes 11 is higher than the top of the limit plates 3 by a predetermined distance.

[0019] A locking block 4 is penetrated through the slide groove 11 and is movable along the length direction of the slide groove 11. The top of the front end of the locking block 4 has a slope 41, so that the slope 41 is inclined toward the upper middle part of the silo 1. A connecting plate 42 is provided at the rear end of the locking block 4. Both sides of the connecting plate 42 protrude from both sides of the locking block 4 and are used to connect the paired limiting grooves 31; when the two sides of the connecting plate 42 slide in the limiting grooves 31 on both sides, the slope 41 is located inside the silo 1, and the overall height of the locking block 4 is less than the predetermined distance between the top of the slide groove 11 and the top of the limiting plate 3.

[0020] The rear end face of the connecting plate 42 is provided with at least one guide rod 43, which is perpendicular to the axis of the silo 1. The outer sleeve of the silo 1 is provided with a driving ring 5, and the silo 1 is provided with a driving device 6 for driving the driving ring 5 to move along the axis of the silo 1. The guide rods 43 are all penetrated by the driving ring 5, and the locking block 4 is movably arranged along the axis of the guide rod 43.

[0021] The principle of the ejection feeding device is as follows:

[0022] To load materials, move the locking block 4 along the guide rod 43 toward the outside of the silo 1. In the above structure, the locking block 4 needs to be moved to the top of the limit plate 3 so that the locking block 4 moves outward from the gap between the limit plate 3 and the top of the chute 11 to facilitate loading into the silo 1. The internal structure of the silo 1 matches the shape of the material, or when designing or packaging the material, the outer contour of the material matches the inner contour of the silo 1. Load the material from the opening at the lower end of the silo 1, and apply pressure to the material to compress the elastic member 2 until the bottom of the material is higher than the position of the locking block 4. In the position; move the locking block 4 along the guide rod 43 into the interior of the silo 1, and insert the connecting plate 42 into the limiting groove 31, and use the limiting groove 31 to limit the connecting plate 42 and the locking block 4 to prevent the locking block 4 from moving to the outside of the silo 1. At this time, the inclined surface 41 will be located in the silo 1 and below the material. Then release the material, and the material will move to the lower end of the silo 1 under the action of the restoring elastic force of the elastic member 2, and push the locking block 4 to move to the bottom of the chute 11. Because the material is restricted by the inclined surface 41 below, the material will not be able to fall out of the opening at the lower end of the silo 1.

[0023] Feeding, when the UAV flies to the air above the predetermined position, it can start feeding, the driving device 6 drives the driving ring 5 to move upward, the driving ring 5 will drive the locking block 4 to move upward along the slide 11 through the guide rod 43, the locking block 4 pushes the material to move above the silo 1, and the material will cause the elastic member 2 to be continuously compressed during the movement, because the connecting plate 42 slides in the limiting groove 31, so the locking block 4 cannot move to the outside of the silo 1 during the upward movement, thereby preventing the material from falling out; when the locking block 4 is higher than the limiting plate 3, that is, the moment when the connecting plate 42 is separated from the limiting groove 31, the bottom of the material will push the locking block 4 to move along the guide rod 43 to the outside of the silo 1 through the inclined surface 41, so that the locking block 4 is moved away from the bottom of the material, and at this time, the material will be quickly ejected under the elastic force of the elastic member 2, accelerating the ejection speed of the material, thereby reducing the influence of the airflow on the material delivery trajectory and improving the position accuracy of the feeding; the lower section of the silo 1 will serve as a guide structure to limit the projection direction of the material, so as to facilitate more accurate delivery of the material.

[0024] Preferably, Figures 1 to 4 As shown, the slide groove 11 penetrates downwardly through the bottom of the silo 1, and the lower end of the silo 1 is connected with a retaining ring 7 through a thread. The retaining ring 7 is an internal thread, and the lower end of the silo 1 is an external thread. After adopting the above structure, when loading the silo 1, the locking block 4 can be moved to the lower end of the silo 1, so that the connecting plate 42 is separated from the limiting groove 31, so that the locking block 4 can be moved to the outside of the silo 1 to avoid the material. After the material is loaded into the silo 1, there is no need to use the material to compress the elastic member 2, so that the locking block 4 can be more easily inserted into the silo 1, and the inclined surface 41 is naturally under the material, the connecting plate 42 is inserted into the limiting groove 31, and then the retaining ring 7 is installed to the lower end of the silo 1 to prevent the locking block 4 from falling, and at the same time ensure that the connecting plate 42 is connected to the limiting groove 31.

[0025] Preferably, Figure 3 , Figure 4 As shown, two guide rods 43 are provided along the direction of the slide slot 11 to improve the connection stability between the locking block 4 and the driving ring 5 .

[0026] Preferably, Figure 1 , Figure 2 As shown, two driving devices 6 are arranged in a circumferential array on the outer wall of the silo 1 to smoothly drive the driving ring 5 to move. The driving device 6 is a linear motor.

[0027] Preferably, Figure 1 , Figure 2 As shown, the silo 1 is a cylindrical structure, and its top is connected to the drone by screws.

[0028] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
