DETAILED DESCRIPTION
[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0019] like Figure 1-4 As shown, the utility model is a helicopter external material spraying equipment, including a hopper 1 and a guide pipe 12, a first motor 2 is fixedly provided on the side wall of the hopper 1, a first rotating shaft 21 is provided at the output end of the first motor 2, a sowing barrel 22 is fixedly sleeved on the outside of the first rotating shaft 21, a leakage hole 24 is provided on the outside of the sowing barrel 22, by turning on the external power switch of the first motor 2, the first rotating shaft 21 at the output end of the first motor 2 starts to rotate through the bearing, and the sowing barrel 22 sleeved on the outside at the position inside the hopper 2 can start to rotate synchronously, and the seeds to be sown can be discharged downward from the leakage hole 24 outside the sowing barrel 22 through the action of gravity, so that the seeds can be evenly transported downward, and a large amount of seeds can be prevented from being blocked in the guide pipe 12 during sowing.
[0020] A driving gear 25 is sleeved on the outside of the other side of the first rotating shaft 21, and the driving gear 25 is meshed with driven gears 3 on both sides. The driven gear 3 is fixedly sleeved on the end of the second rotating shaft 31. The other end of the first rotating shaft 21 that passes through the hopper 2 is fixedly sleeved with a driving gear 25. When the first rotating shaft 21 starts to rotate at the hopper 2 through the bearing, it can drive the driving gear 25 to start rotating synchronously, and the driven gear 3 meshed with the side of the driving gear 25 can also start rotating. The driven gears 3 at both locations are fixedly set on the second rotating shaft 31, and can drive the second rotating shaft 31 to start rotating.
[0021] A cleaning rod 32 is fixedly sleeved on the outside of the second rotating shaft 31, and bristles 33 are provided on the cleaning rod 32. The cleaning rod 32 fixedly set on the outside of the second rotating shaft 31 starts to rotate inside the hopper 2, and the multiple bristles 33 set on the cleaning rod 32 start to rotate synchronously. The bristles 33 are rotated to connect to the leakage holes 24 on the sowing barrel 22, and the bristles 33 match the leakage holes 24. The bristles 33 on the cleaning rod 32 can extend into the leakage holes 24 and push out the seeds blocked in the leakage holes 24 to prevent the seeds from blocking the inside of the leakage holes 24 and causing the seeds to be unable to be uniformly transported downward, thereby ensuring the smoothness of seed transportation.
[0022] A mounting plate 24 is fixedly provided on the side wall of the guide tube 12, and an electric push rod 41 is provided below the mounting plate 24. A slider 42 is provided at the output end of the electric push rod 41, and a receiving groove 43 is provided in the slider 42. Two transverse plates 13 are provided on the inner wall of the guide tube 12, and through holes 14 are provided in each of the transverse plates 13. When the receiving groove 43 and the through holes 14 at the upper transverse plate 13 and the receiving groove 43 are at the same vertical height, the seeds dropped from the upper sowing barrel 22 enter the through holes 14 and enter the receiving groove 43. By turning on the switch of the electric push rod 41, the slider 42 is slidably connected to the guide tube 12, and the electric push rod 41 pulls the slider 42 to start to retract inwardly. During the inward movement of the slider 42, the receiving groove 43 can be driven to retract inwardly, and the receiving groove 43 is moved to the through holes 14 at the lower transverse plate 13, and the seeds inside the receiving groove 43 fall from the through holes 14 to carry out sowing.
[0023] A second motor 44 is provided on the inner wall of the slider 42, and a threaded rod 45 is provided at the output end of the second motor 44. The threaded rod 45 is threadedly connected to a limit block 46. By turning on the switch of the second motor 44, the threaded rod 45 at the output end of the second motor 44 starts to rotate inside the limit block 46, and the limit block 46 is slidably connected to the accommodating groove 43. The limit block 46 starts to slide forward inside the slider 42, and the limit block 46 starts to move forward in the accommodating groove 43, which can limit the usable space inside the accommodating groove 43 and control the sowing amount of seeds below according to the needs of seed sowing, so as to avoid excessive sowing in the sowing area during sowing, resulting in poor planting effect.
[0024] In the above scheme, a mounting plate 11 is fixedly provided above the hopper 1, and a mounting hole is provided on the mounting plate 11. The mounting hole on the mounting plate 11 is connected to the connecting rod under the helicopter to install the spraying equipment externally.
[0025] In the above scheme, a sealing cover 23 is provided on the sowing barrel 22, and a cover plate is provided above the hopper 2. The cover plate is opened, and the sealing cover 23 is opened again. The setting of the sealing cover 23 is convenient for placing seeds into the interior of the sowing barrel 22. A buckle for fixing the sealing cover 23 is provided between the sealing cover 23 and the sowing barrel 22, so that the sealing cover 23 will not be separated from the sowing barrel 22 when the sowing barrel 22 rotates.
[0026] In the above scheme, four shock-absorbing rods 16 are fixedly connected below the hopper 1, and buffer springs 17 are sleeved on the outside of the shock-absorbing rods 16. Buffer blocks 15 are connected below the shock-absorbing rods 16. When the helicopter stops on the ground after seed sowing, the buffer blocks 15 below are supported to the ground. The shock-absorbing springs 17 can cooperate with the buffer blocks 15 to reduce the impact force and avoid damage to the spraying equipment.
[0027] Working principle:
[0028] This type of helicopter external material spraying equipment, when working, connects the mounting plate 11 above the hopper to the helicopter, puts the seeds to be sown in the sowing barrel 22, and controls the helicopter to the ground where the seeds are to be sown. By turning on the switch of the first motor 2, the sowing barrel 22 and the cleaning rod 32 start to rotate inside the hopper 2, which can ensure that the seeds fall evenly while avoiding the seeds from being blocked at the leakage hole 24 at the sowing barrel 22, thereby ensuring the uniformity of the seeds during the sowing process. By turning on the switch of the second motor 44, the size of the containing groove 43 is controlled by the movement of the limit block 46, thereby controlling the amount of seeds to be sown, and accurately controlling the amount of seeds to be sown at a single time, thereby improving the accuracy of planting, and avoiding the influence of the planting effect due to the large or small amount during the seed planting process. Through the repeated movement of the electric push rod 41, the seeds in the containing groove 43 can be driven to enter the through hole 14 and fall to the ground for sowing.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
