[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution: a material throwing device for multiple operating scenarios, including a material cylinder 1 and an electrical control mechanism installed on the material cylinder 1. The material cylinder 1 is provided with a material tray 2 and a driving component that drives the material tray 2 to rotate. The material tray 2 forms multiple material dropping bins 201 arranged in a ring. The material cylinder 1 is provided with a material feeding structure.

[0032] The inside of the barrel 1 can contain a large amount of material, and the plurality of material falling bins 201 in the material disc 2 are used for filling before the material is put in, and the material disc 2 is controlled to rotate by the driving member, so that the material in the barrel 1 can be quantitatively thrown from multiple points, and continuous operation can be realized.

[0033] The material disc 2 is detachably designed relative to the barrel 1, and the user can replace the material disc 2 according to the material to be thrown, and different material discs 2 can realize throwing of materials of different sizes. The hatch can also be designed according to special materials to meet the throwing operation of various materials, which has strong expansibility. The fewer the number of material falling bins 201 distributed relative to the material disc 2, the larger the aperture, so as to cope with the throwing of materials of different sizes.

[0034] The bottom of the barrel 1 is fixedly provided with a bottom cover 12, and the bottom cover 12 is formed with a material falling groove 13. When the material falling bin 201 is aligned with the material falling groove 13, the material pushing structure pushes the material above the material falling bin 201 away, and the material entering the material falling bin 201 is thrown out through the material falling groove 13.

[0035] Each material falling bin 201 on the material disc 2 can fall into one material. In the working condition, the material disc 2 is controlled to rotate by the driving member, and the material will rotate to the material falling groove 13 one by one with the rotation of the material disc 2. The material pushing structure pushes the material accumulated above the material falling bin 201 away, so that there is only one material above the material falling groove 13 each time, and the material falls from the material falling port, thereby satisfying the accurate control of the material throwing.

[0036] Specifically, as shown in Figure 4 and Figure 5 , the driving member includes a rudder 4 installed in the barrel 1, and the output end of the rudder 4 is installed with an engagement transmission assembly, and the side wall of the material disc 2 is formed with a driven tooth 3.

[0037] The rudder 4 is a prior art, which is a device for converting electrical signals into mechanical motion, and can accurately adjust the rotation angle according to the input control signal to realize accurate position control. When the rudder 4 operates, the driven tooth 3 will drive the material disc 2 to rotate under the action of the engagement transmission assembly.

[0038] The engagement transmission assembly includes a driving tooth 6 rotatably connected to the bottom cover 12, and the driving tooth 6 is in meshing connection with the driven tooth 3. The driving tooth 6 is embedded with a rudder plate 5, and the rudder plate 5 is slidably sleeved on the outside of the output shaft of the rudder 4.

[0039] The driving tooth 6 is fixedly provided with a plug rod 601, and the rudder plate 5 is formed with a plug groove 501 matched with the plug rod 601. The output shaft of the rudder 4 is in sliding fit with the rudder plate 5 through the spline.

[0040] The steering wheel 5 is an output component of the steering gear 4, which is directly connected to the output shaft of the steering gear 4. When the steering gear 4 receives a control signal, the output end drives the steering wheel 5 to rotate. The steering wheel 5 can convert the rotary motion of the steering gear 4 into angular changes to adapt to different application requirements. Through external control signals, the position and angle of the steering wheel 5 can be accurately adjusted, which allows the motion output of the steering gear 4 to drive the teeth 6.

[0041] Through the plug-in cooperation of the plug rod 601 and the slot 501, and the sliding cooperation of the output shaft of the steering gear 4 and the steering wheel 5 through the spline, when the output shaft rotates, the steering wheel 5 can be driven to rotate through the spline, and the steering wheel 5 drives the driving teeth 6 fixed with the plug rod 601 to rotate through the slot 501. Through this sliding plug-in cooperation mode, the user can conveniently disassemble and replace the driving teeth 6.

[0042] Specifically, as shown in Figures 3-5 The bottom cover 12 is fixedly provided with a shaft column 101 coaxially distributed with the tray 2, and the tray 2 is rotatably sleeved outside the shaft column 101. The material stirring structure is a baffle 9, which is fixed on the shaft column 101 by bolts and protrudes upward beyond the end of the tray 2. When the dropping bin 201 is rotated to align with the dropping chute 13, the baffle 9 pushes away the material above the dropping bin 201 and blocks the opening of the dropping bin 201.

[0043] When the tray 2 rotates, the tray 2 will rotate along the shaft column 101 to realize the circulation of the material. During the rotation of the dropping bin 201 to align with the dropping chute 13, the baffle 9 will push away the remaining material above the dropping bin 201. As the dropping bin 201 aligns with the dropping chute 13, the top opening of the dropping bin 201 will be blocked by the baffle 9, ensuring that there is only one material above the dropping chute 13 each time.

[0044] Specifically, as shown in Figure 4 and Figure 5 The material cylinder 1 is provided with a dropping sensor 7 for sensing and counting the material dropped into the dropping chute 13.

The infrared dropping sensor 7 usually includes an infrared emitter (IR emitter) and an infrared receiver (IR receiver). The emitter is used to emit infrared radiation of a specific wavelength, and the receiver is used to detect the reflected infrared radiation.

[0046] The material falls from the material falling groove 13, the material falling is detected through the material falling sensor 7 arranged in the material cylinder 1, the number of material falling is counted, and corresponding times of flashing are carried out, if the material falling bin 201 is out of material due to special circumstances, the material disc 2 continues to rotate until the required amount of material is ensured, if the material falling is not detected during one rotation, the material disc 2 is reversed for one rotation, if there is still no material, the material cylinder 1 is fed back as being out of material.

[0047] The lamp strip 11 is a three-color lamp, the color of the lamp strip 11 flashes after the material is out, prompting the material is out, other faults, such as blocked rotation, too much material and the like, correspond to different colors to flash, so as to directly feed back the situation to the user.

[0048] When the material cylinder 1 completes the corresponding number of material dropping at one work point, a signal is given to execute work at the next work point until the work is completed or the material is returned due to lack of material.

[0049] The electric control mechanism comprises a module shell 15 arranged at the side end of the material cylinder 1, a control module 14 is arranged in the module shell 15, and a wire harness 16 connected with the output end of the mounting device is arranged on the module shell 15; the side wall of the material cylinder 1 is rotatably connected with a threaded thimble 8, and the material cylinder 1 is arranged on the mounting device through the threaded thimble 8.

[0050] The output end of the control module 14 is electrically connected with the input end of the rudder 4 and the lamp strip 11. The control module 14 is the core part of the unmanned aerial vehicle throwing system, which is responsible for receiving instructions, controlling throwing actions and ensuring the accuracy and safety of throwing, and realizing the normal work of the thrower.
