The liquid container 10 provided in the embodiment of the invention is detachably connected to the machine body 30, so that the liquid container 10 can be quickly detached from the machine body 30, and the use is convenient. Specifically, the container body 12 of the liquid container 10 has the lower case 124 and the upper case 126 that are integrally formed, the lower case 124 and the upper case 126 together form the liquid storage cavity 120 for containing the liquid medicine to be sprayed, and the liquid injection port 121 and the liquid outlet 122 that are mutually communicated with the liquid storage cavity 120 are provided, so that the liquid medicine is conveniently poured into the liquid storage cavity 120 and discharged from the liquid storage cavity 120, and when the liquid container 10 is mounted on the body 30, the lower case 124 is inserted into the body 30 to limit the degree of freedom of lateral movement of the liquid container 10, and the upper case 126 is fastened to the body 30 to limit the degree of freedom of movement of the liquid container 10 in the vertical direction, so that the liquid container 10 is firmly mounted on the body 30, and since the upper case 126 and the body 30 are mutually fastened, the convenience in mounting and dismounting of the liquid container 10 and quick replacement of the liquid container 10 are ensured.
The liquid inlet 121 and the liquid outlet 122 are respectively and independently provided on the container main body 12; or the liquid injection port 121 and the liquid outlet port 122 may be the same hole provided on the container body 12.
Referring to fig. 1 and 8-10, in this embodiment, the lower case 124 and the upper case 126 are both substantially square, such as rectangular parallelepiped. The upper box 126 and the lower box 124 are arranged along the vertical direction shown in the figure, when the liquid storage cavity 120 is filled with the liquid medicine to be sprayed, the lower box 124 is inserted into the body 30, and the upper box 126 is propped against the body 30 under the action of gravity of the liquid medicine to be sprayed and is fastened with the body 30 to be fixed on the body 30, so that the liquid container 10 is prevented from shaking in the flight process of an aircraft, and unstable flight is caused.
In this embodiment, the aircraft may be used in the agro-farming industry for performing work activities such as pesticide spraying or water spray. Of course, the aircraft can also be used for spraying fire-extinguishing liquid in forest fires and the like.
When the liquid container 10 is mounted on the body 30, the lower case 124 is inserted into the body 30 to position the liquid container 10, accurately position the liquid container 10 at a predetermined position on the body 30, and fasten the upper case 126 to the body 30 to fix the liquid container 10, so that the liquid container 10 is mounted on the body 30, and the mounting and dismounting of the liquid container 10 are rapid and convenient, thereby improving the working efficiency.
When the liquid medicine needs to be replaced after the single operation of the aircraft is completed, the liquid container 10 can be quickly detached from the machine body 30, and the liquid container 10 filled with the liquid medicine in advance is quickly installed on the machine body 30, so that the time for filling the liquid medicine, which is additionally occupied after the aircraft falls, can be saved, the installation and the detachment of the liquid container 10 are convenient and quick, and the operation efficiency of the aircraft is improved.
Referring to fig. 1 and 8-10, further, the upper case 126 is provided with a fastening structure 20 that is fastened to the body 30. The fastening structure 20 is used for fastening the upper case 126 with the main body 30, so as to fix the liquid container 10 on the main body 30 conveniently, and make the installation and the disassembly of the liquid container 10 on the main body 30 convenient and quick.
Preferably, the fastening structure 20 may be a matching structure of the fastener 24 and the fastening slot 22, or may be a matching structure of the fastener and the strap, so as to limit the freedom of the liquid container 10 to move up and down along the body 30, which is not limited thereto.
Referring to fig. 8 to 10, further, the cross-sectional area of the lower case 124 in the direction of looking down the body 30 is smaller than the cross-sectional area of the upper case 126. It will be appreciated that the direction of the upper case 124 and the lower case 126 is from top to bottom in the drawing, and the cross section of the upper case 126 in the direction of the upper case 30 is a plane formed in the front-rear and left-right directions in the drawing. The lower case 124 is located below the upper case 126, and the cross-sectional area of the lower case 124 is smaller than that of the upper case 126, after the lower case 124 is inserted into the body 30, the upper case 126 is supported on the body 30, so that the installation of the liquid container 10 is facilitated, and thus, the pre-batch filling can be realized.
Compared with other liquid containers 10 with the same box volume and the same height, the liquid container 10 in this embodiment can reduce the amount of movement of the liquid in the unit volume in the lower box 124 due to the small cross-sectional area of the lower box 124, so as to reduce the shaking phenomenon of the liquid medicine in the lower box 124 in the flight process of the aircraft, and ensure that the aircraft can fly stably. For example, the liquid medicine in the liquid container 10 may change suddenly with the flying posture of the aircraft during the flying process, so that the liquid medicine in the liquid container 10 may slosh.
During the flight operation of the aircraft, the liquid medicine in the upper tank body in the liquid container 10 flows out of the lower tank body from the liquid outlet 122 under the action of gravity of the liquid medicine. That is, when the liquid medicine in the liquid storage chamber 120 is reduced to be located in the lower case 124, the flying posture of the aircraft is significantly changed. And because the cross-sectional area of the lower case 124 along the liquid storage cavity 120 is smaller, the amount of movement of the liquid medicine in the unit volume is reduced, and when the flying attitude of the aircraft changes, the liquid medicine in the lower case 124 can reduce the sloshing phenomenon, so that the aircraft can be controlled to fly stably.
In other embodiments, a grid may be disposed in the container body 12 to reduce sloshing of the liquid medicine, so as to simplify the production process of the liquid container 10 and reduce the production cost of the liquid container 10.
Referring to fig. 8 and 10, further, the upper case 126 and the lower case 124 form a "T" shape or an inverted "L" shape. The upper case 126 and the lower case 124 are in a vertically stacked structure, and approximately form a T shape or an inverted L shape, on one hand, the lower case 124 is inserted into the main body 30 and the upper case 126 is supported on the main body 30, on the other hand, the cross-sectional area of the lower case 124 is smaller than the cross-sectional area of the upper case 126, so as to reduce the liquid medicine sloshing phenomenon in the liquid storage cavity 120 during the operation of the aircraft, and ensure the flying stability of the aircraft.
Referring to fig. 10, further, a receiving space (not shown) is defined by a bottom wall of the upper case 126, a side wall of the lower case 124, and a plane passing through a bottom end of the bottom wall of the upper case 126 away from the lower case 124 and a bottom end of the side wall of the lower case 124, and the liquid outlet 122 is located in the receiving space. It will be appreciated that when the liquid container 10 is placed on the bottom surface, the bottom wall of the upper case 126 is supported on the ground at the end far from the lower case 124 and the bottom end of the side wall of the lower case 124, respectively, while the liquid outlet 122 is located in the receiving space and does not directly contact the ground.
Referring to fig. 1 to 10, further, the machine body 30 includes a machine head 32 having a support plate 34, and a frame 35 fixedly connected to the support plate 34 and enclosing the support plate 34 to form a through space 36, the lower case 124 is inserted into the through space 36, and the upper case 126 is overlapped on the support plate 34 and fastened on the support plate 34. The upper box 126 is lapped on the supporting plate 34 and buckled with the supporting plate 34, and the lower box 124 is inserted into the through space 36 to insert the liquid container 10 into the body 30, so that the aircraft falls on the ground, and the liquid outlet 122 arranged at the bottom of the lower box 124 is not directly contacted with the ground due to the support of the supporting plate 34, so as to play a role in protecting the liquid outlet 122.
Referring to fig. 8 and 10, further, the liquid outlet 122 is disposed at a side of the upper case 126 connected to the lower case 124, and the liquid container 10 further includes a weight member 14 disposed at a bottom of the lower case 124 and a liquid hose 15 communicating the weight member 14 and the liquid outlet 122. The liquid outlet 122 and the lower case 124 are disposed on the same side of the upper case 126, and the cross-sectional area of the lower case 124 is smaller than that of the upper case 126, so that the liquid outlet 122 can be protected by using the height of the lower case 124, and the liquid leakage caused by deformation of the liquid outlet 122 can be avoided when the liquid container 10 is lifted.
In order to spray all the liquid medicine in the lower tank 124, the liquid outlet 122 is communicated with the weight 14 at the bottom of the lower tank 124 by the liquid delivering hose 15, and when the liquid medicine in the liquid storing cavity 120 is gradually reduced, the liquid medicine at the bottom of the lower tank 124 is delivered to the liquid outlet 122 by the liquid delivering hose 15, and one end of the liquid delivering hose 15 is always kept at the bottom of the lower tank 124 under the action of gravity by arranging the weight 14.
In this embodiment, the weight 14 and the infusion hose 15 are made of a corrosion resistant material, for example, the material of the infusion hose 15 may be plastic, and the material of the arrangement may be ceramic or alloy material.
Referring to fig. 8 to 10, further, the container body 12 further includes a handle 128 integrally formed on the upper case 126, the handle 128 and the lower case 124 are respectively located at two opposite sides of the upper case 126, and a lifting direction of the handle 128 coincides with a gravity center direction of the liquid storage cavity 120. The liquid container 10 is convenient to disassemble and assemble by providing the handle 128 so that the liquid container 10 can be quickly inserted into the body 30 or taken out from the body 30 by pulling the handle 128. The handle 128 is integrally formed with the upper case 126, simplifying the process of the liquid container 10 and securing the strength of the liquid container 10. The handle 128 is disposed at a middle position of the upper surface of the upper case 126 in the width direction, so that the lifting direction of the handle 128 coincides with the gravity center direction of the liquid storage cavity 120 formed by the lower case 124 and the upper case 126, so as to ensure that the liquid container 10 can be inserted into the body 30 or taken out from the body 30 along the gravity direction during the process of lifting the handle 128.
