The switching motor can drive the switching screw to rotate, and the thread action between the switching screw and the switching movable block pushes the switching movable block to move along the sliding column, thereby driving the connecting rod on the right side and the mounting frame to move horizontally left and right;

Further, it also includes a center release unit, a mounting limit assembly and a release control assembly. A center release unit is installed at the bottom of the right end of the left mount frame, and the center release unit is respectively provided with a mount limit assembly and a release control assembly. components. The central delivery unit can centrally mount multiple items that need to be delivered in the lower middle of the drone. Since the items mounted here are close to the middle of the drone, it is suitable for heavier loading and delivery, and the release control component controls The activity of mounting the limit component to realize the control of the delivery of the central delivery unit.

Further, the central delivery unit includes an installation cylinder, a bottom ring, an annular flange, a spoke rod, a core seat, a movable shaft, a delivery swing rod and an arc-shaped mounting slot, and the installation cylinder is fixedly installed on the left hanging At the bottom of the right end of the carrier, a bottom ring is fixedly connected to the inner side of the bottom of the installation cylinder, and an annular convex edge is connected to the inner top of the bottom ring, and four mounting limit components are installed in a circular array on the bottom ring and the annular convex edge , the middle part of the annular protruding edge is fixedly connected with a core seat through a spoke rod, and four gaps corresponding to the mounting limit components are opened in the annular array on the outer peripheral side of the core seat, and the openings are movably connected to the throwing swing rod through a movable shaft An arc-shaped mounting slot is opened on the upper side of the throwing lever.

Put the sling on the top of the item to be dropped on the swing rod to realize the mounting of the item, and the arc-shaped mounting slot can limit the sling on the top of the item to be dropped, so as to avoid the sling being dropped when the flight is unstable Sliding on the pendulum, the mounting limit component supports the lower end of the delivery pendulum, releasing the control component can push the mounting limit component away from the end of the delivery pendulum. At this time, the delivery pendulum is affected by the gravity of the item Through the movement of the movable shaft, the sling on the delivery pendulum is released to realize the delivery of articles.

Further, the mounting limit assembly includes a limit slide plate, a compression spring, a control riser, a wedge block and a slide groove, and four slide grooves are opened in the side ring array of the annular flange, and the sliding connection in the slide groove is limited. Position slide plate, the limit slide plate is located on the upper side of one end inside the annular convex edge, corresponding to the bottom of the end of the throwing swing rod away from the core base, the end of the limit slide plate located on the outer side of the annular convex edge is connected to the control riser, and the top of the control riser A wedge-shaped block is fixedly connected, and the side of the wedge-shaped block is provided with a wedge-shaped surface.

If only one rotary rod is inserted in the card slot, the control motor will drive the connecting plate to rotate counterclockwise, and the connecting plate will drive the circular release block to move counterclockwise through the rotary rod. When the circular release block encounters the wedge-shaped surface of the wedge-shaped block, the frictional contact between the circular release block and the wedge-shaped surface pushes the wedge-shaped block and the control vertical plate to move outward while compressing the compression spring, so that the limit slide plate loses the support of the delivery swing rod , so that the items mounted on the delivery pendulum are released, and the control motor continues to work, and the items on the four delivery pendulums can be continuously released in sequence. If two rotary rods are inserted into the symmetrical slots on both sides of the connecting plate, Repeat the above delivery steps, and the items mounted on the four launch levers can be divided into two symmetrical deliveries. At this time, the stable distribution of the center of gravity of the drone can be ensured. Rotate the rod, repeat the above-mentioned release steps, and the items mounted on the four release swing rods can be released synchronously and at one time.

Compared with the prior art, the beneficial effects of the present invention are: the drone-borne continuous delivery device has the following advantages:

1. Items distributed by linear mounts can be placed gradually and continuously from both ends to the middle. Items distributed by linear mounts can be placed alternately from the left and right ends through the delivery mode switching component, and items distributed by linear mounts can also be controlled from left to right.

Supporting, at this time, the drop pendulum 59 can be lowered, a sling for loading items can be put on the drop pendulum 59, the release pendulum 59 is lifted to keep it horizontal, and then the control riser 63 is released, and the compression spring 62 Rebound, pushing the control vertical plate 63 and the limit slide plate 61 to slide along the slide groove, so that the end of the limit slide plate 61 supports the end bottom of the throwing swing bar 59 away from the core seat 57, if the limit slide plate 61 is Release the control assembly 7 and push away from the throwing fork 59, the limit slide plate 61 will lose the support to the bottom of the throwing fork 59, and the articles on the throwing fork 59 will be dropped.

The release control assembly 7 includes a control motor 71, a connecting plate 72, a draw-in slot 73, a screw 74, a rotating rod 75 and a circular release block 76, and a control motor 71 is installed in the top circular groove of the core seat 57, and the top of the control motor 71 The output shaft of the connecting disc 72 is connected with a connecting disc 72, and the outer circumferential side of the connecting disc 72 is provided with four card slots 73 in an annular array, and one end of the screw rod 75 is inserted into the card slot 73, and the position corresponding to the card slot 73 on the top of the connecting disc 72 is threadedly connected with The other end of the screw 74 and the rotary rod 75 is connected with a circular release block 76 corresponding to the wedge block 64 .

During use, the screw 74 is used to stably fix the rotating rod 75 in the draw-in groove 73. If only the rotating rod 75 is inserted in one draw-in groove 73, the work of the control motor 71 drives the connecting disc 72 to rotate counterclockwise, and the connecting disc 72 rotates counterclockwise through the rotating rod 72. The rod 75 drives the circular release block 76 to move counterclockwise, and the circular release block 76 encounters the wedge-shaped surface of the wedge-shaped block 64. Due to the frictional contact between the circular release block 76 and the wedge-shaped surface, the wedge-shaped block 64 and the control vertical plate 63 are pressed against the spring 62 compresses and moves outwards at the same time, so that the limit slide plate 61 loses the support of the delivery fork 59, allowing the items mounted on the delivery fork 59 to be dropped, and the control motor 71 continues to work, and the four delivery fork 59 can be successively and continuously 59 items are put in, if two rotary rods 75 are plugged into the symmetrical slots 73 on both sides of the connection plate 72, and the above-mentioned throwing steps are repeated, the items mounted on the four throwing swing rods 59 can be divided into two symmetrical Launching, at this time, the stable distribution of the center of gravity of the drone can be ensured. If all the upper rotating rods 75 are inserted in the four card slots 73 outside the connecting plate 72, and the above-mentioned launching steps are repeated, the four launching swing bars 59 can be hung up. The loaded items are delivered synchronously at one time.
