Support rod in frame is connected to unmanned plane in an articulated manner, and the cushion effect of pneumatic structure is by as low as during unmanned plane lands
Greatly, the shock of a fall power is slowly laid down, plays the effect of bradyseism.
The utility model realizes that above-mentioned purpose uses following technical scheme:
Plant protection plant seeds by airplane unmanned plane bradyseism undercarriage, it includes support plate, support rod, mounting base.
The support plate is equipped with two to be parallel to each other；Support rod is U-shaped structure, and the bipod of support rod respectively corresponds
The support plate being parallel to each other, the support rod also are provided with two, and two support rods are before and after support plate with splayed structure
Symmetrically set；The top of two support rods is equipped with mounting base；It is connected between the support plate and support rod by pneumatic device
It connects.
The pneumatic device includes piston；Internal before and after support plate to be respectively equipped with hollow portion, hollow portion is close to support plate
Through slot is provided with above the position at center；The piston is mounted in through slot, and the front end of piston corresponds to hollow in support plate
Portion；The support rod is articulated on piston, and support bar top is hinged to mounting base.
The bottom surface of hollow portion is equipped with equally distributed several semi-circular recesses in support plate.
The groove is pyramidal structure, from the inside to the outside the reduced diameter of groove.
Further, it is attached between two support rods by extension spring.
Further, the corresponding position of the support bar top is respectively equipped with angular wheel, leads between angular wheel
It crosses connecting rod to be driven, the end of connecting rod is respectively equipped with the angular wheel being meshed with the angular wheel on support rod.
The utility model has the advantages that by adopting the above technical scheme
The support plate of the present apparatus realizes the buffering for buffering and then realizing to unmanned plane, knot by the way of pneumatic to support rod
Structure is easy, will not increase additional burden to fuselage；Secondly, the groove in pneumatic mechanism uses descending diameter structure,
It matches with descending process is impacted in unmanned plane landing, can effectively realize the effect of bradyseism.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of groove.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Plant protection plant seeds by airplane unmanned plane bradyseism undercarriage as shown in Figure 1, it includes support plate 1, support rod 2, mounting base 3.
The support plate 1 is equipped with two to be parallel to each other；Support rod 2 is U-shaped structure, and the bipod of support rod 2 is right respectively
The support plate 1 being parallel to each other should be arrived, the support rod 2 also is provided with two, and two support rods 2 are before and after support plate 1 with eight
Character form structure is symmetrical and sets；The top of two support rods 2 is equipped with mounting base 3；Pass through between the support plate 1 and support rod 2
Pneumatic device is connected.
The pneumatic device includes piston 401；1 front and back of support plate is internal to be respectively equipped with hollow portion, and hollow portion is close to branch
Through slot 101 is provided with above the position at 1 center of fagging；The piston 401 is mounted in through slot 101, and the front end of piston 401 is corresponding
To the hollow portion in support plate 1；The support rod 1 is articulated on piston 401, and mounting base 3 is hinged at the top of support rod 1.
As shown in Fig. 2, the bottom surface of hollow portion is equipped with equally distributed several semi-circular recesses 102 in support plate 1.
The groove 102 is pyramidal structure, from the inside to the outside the reduced diameter of groove 102.
It is attached between two support rods 1 by extension spring 5.
The corresponding position in 1 top of support rod is respectively equipped with angular wheel 103, passes through between angular wheel 103
Connecting rod 104 is driven, and the end of connecting rod 104 is respectively equipped with the angular wheel being meshed with the angular wheel 103 on support rod 1
103。
The present apparatus is installed on uav bottom during use, when unmanned plane landing, under gravity, branch
Strut drives the piston of bottom mobile to outside, and hollow portion is equivalent to the cavity of piston, and the groove of bottom setting is then exhaust
The exhaust velocity in hole, gas vent is small in size compared to hollow portion, so can guarantee that piston slowly moves outward.
In order to preferably alleviate buffering when unmanned plane just lands, pyramidal structure is set by groove, piston is in
The diameter in portion, corresponding groove is bigger, and corresponding deflation rate is more preferable, and piston movement speed when starting is fast, can be to most opening
The impact of beginning is quickly buffered, and as time goes by, the impact of unmanned plane is gradually reduced, and the corresponding groove of sliding block at this time
Diameter reduce, deflation rate reduce, then the buffer of unmanned plane is slowed down therewith, to complete the landing work of unmanned plane.
In order to guarantee that the synchronous of support rod is opened, angular wheel transmission mechanism is set at top, makes the aperture of two support rods
It is consistent.And it is connected to the spring between two support rods and then can guarantee and two support rods and piston is driven to lean on after lift-off to middle part
Hold together, prepares for landing next time.
