When feeding, please refer to Figures 11, 12a, 12b, and 13, firstly, after the elastic fastener 237 of the second control board 23 is disengaged from the second latching portion 218, then turn the second handle 236 rotates clockwise or counterclockwise, so that the first and second double-row holes 232 and 233 of the second control board 23 are simultaneously staggered with the first and second discharge holes 215 and 216 of the bottom plate 213. At this time, When the second control board 23 is rotated clockwise and locked on the first locking portion 217 , the first single-row holes 234 located in the counter-clockwise direction of the first double-row holes 232 will be transferred to the first single-row holes 234 of the bottom plate 213 . A discharge hole 215 is communicated, and the second discharge hole 216 of the bottom plate 213 is closed and blocked, forming a single discharge state of the first discharge hole 215, and the fertilizer is discharged into the row along the first pipe 254 In the air duct 19, the fertilizer is discharged from the first discharge port 191 of the air exhaust duct 19 through the blower 18 to achieve a state of unilateral discharge; on the contrary, when the second control board 23 is in the state of bilateral discharge When rotated counterclockwise and locked on the third buckle portion 219 , the second single-row holes 235 located in the clockwise direction of the second double-row holes 233 will be transferred to form communication with the second discharge holes 216 of the bottom plate 213 , The first discharge hole 215 of the bottom plate 213 is closed and blocked to form a single discharge state of the second discharge hole 216. The fertilizer is discharged into the exhaust pipe 19 along the second conduit 255, and then passes through the discharge pipe 19. The blower 18 discharges the air to discharge the fertilizer from the second discharge port 192 of the air discharge pipe 19 to achieve the state of unilateral discharge.

In addition, the electric fertilizer applicator not only includes the adjustment of bilateral and unilateral discharge, but also the adjustment of the amount of fertilizer to be discharged. Continued, please see from Figures 12, 15a, and 15b. The third control panel 24 When the third handle 244 is positioned through the insertion of the latch unit 246 with the first positioning hole 256 of the base plate 25 , the first and second openings 242 and 243 of the third control plate 24 are completely connected to the first positioning hole 256 of the base plate 25 . 2. The second lead-out holes 252, 253 make the fertilizer outlet form the state of the maximum amount, whereby, when the third handle 244 is separated from the first positioning hole 256 and rotates to the second positioning hole 257 or the third positioning hole When the 258 is inserted and positioned, the first and second openings 242, 243 of the third control board 24 will gradually stagger the first and second lead-out holes 252, 253, so that the first and second openings 242, 243 The overlapping and communicating parts of the first and second lead-out holes 252 and 253 are gradually reduced, and the outlet of fertilizer is further reduced to adjust the amount of fertilizer output.

Furthermore, in another embodiment of the platform 10 , as shown in FIG. 16 , the driven wheel 16 can be a single-wheel structure with only one wheel seat 163 , and the wheel seat 163 is provided with a hexagonal axle post 164 It is assembled and fixed with the hexagonal axle hole (not shown in the figure) of the axle frame 15, and the wheel base 163 is further provided with a parking frame 165 to facilitate the parking and positioning of the driven wheel 16 set on a single wheel to avoid tipping.

With the structure of the above-mentioned specific embodiment, the following benefits can be obtained: (1) The fertilizer applicator of the present invention achieves the electric self-propelled ability through the hub motor 131 of the driving wheel 13, the fertilizer bucket carries solid fertilizer, and is sprayed by the blower. Spreading fertilizers to assist users in fertilizing operations, so that users can easily complete the fertilizing operations in the entire agricultural area, saving time and effort, and through the adjustment and limitation of the power of the hub motor 131, to achieve uniform speed and uniform amount of spraying Fertilization effect, help to improve fertilization efficiency.

(2) The fertilizer bucket 20 is opened and closed through the first control panel 22 to open and close the fertilizer drop and discharge, and indeed the walking of the fertilizer applicator and the fertilizer discharge area are separated. When the fertilizer applicator is about to turn or go backwards, the fertilizer applicator can be relaxed. 227, and the first handle 224 is pulled back to the original position through the elastic member 225, so that the first and second discharge holes 222, 223 of the first control board 22 and the first and second discharge holes 222, 223 of the bottom plate 213 The second discharge holes 215 and 216 are staggered and closed, so as to stop fertilization, avoid repeated fertilization in agricultural areas, and achieve the purpose of preventing the death of excessive nutrients and fertilizer waste.

(3) The fertilizer applicator can adjust and control the bilateral discharge or unilateral discharge of the fertilizer through the second control panel 23, which can be easily adjusted and changed according to the agricultural area planning. In addition, the fertilizer can be adjusted through the third control panel 24. The size of the outlet can adjust the output diameter according to the fertilizer demand of the crops, so as to achieve an appropriate and even amount of fertilization, and improve the growth and survival rate of agricultural plants.

(4) The exhaust pipe 19 can be optionally equipped with a straight pipe, a curved pipe or a side opening closed straight pipe, etc., which can be used for spreading or strip fertilizing in vegetable and vegetable gardens, so as to achieve the purpose of flexible application to different farmlands. Helps to improve the practicability of the fertilizer applicator.

To sum up, this creation has indeed achieved a breakthrough structural design, and has improved new content, and at the same time can achieve industrial utilization and progress, and this creation has not been seen in any publications, and it is also novel. In accordance with the provisions of the relevant laws and regulations of the Patent Law, the patent application for a new type of patent has been filed in accordance with the law.

Only the above is only a preferred embodiment of the present creation, and should not be used to limit the scope of implementation of the present creation; that is, all equivalent changes and modifications made according to the scope of the patent application for this new model should still belong to the present new model. covered by the patent.
