[0037] like Figure 1-5 As shown, this embodiment proposes a backpack fertilizer applicator for agricultural fertilization, comprising a box body 1, a stirring and spreading mechanism 2 is arranged on the top of the box body 1, a spraying component 3 is arranged on one side of the box body 1, and a limiting component 4 is arranged on one side of the stirring and spreading mechanism;

[0038] The stirring and spreading mechanism 2 includes a partition frame 201, a first motor 202, a stirring blade 203, a leakage hole 204, a guide plate 205, a guide pipe 206, a transmission pipe 207, a second motor 208, a spiral transmission blade 209, a spreading pipe 210 and a shoulder strap 211. The partition frame 201 is fixedly connected to the inner wall of the box body 1, the first motor 202 is bolted to the top of the box body 1, and multiple stirring blades 203 are fixedly connected to the output end of the first motor 202. The leakage hole 204 is opened inside the box body 1, the guide plate 205 is fixedly connected to the inner wall of the box body 1, the guide pipe 206 is fixedly connected to the inner wall of the box body 1 and is located at the bottom of the leakage hole 204, the transmission pipe 207 is fixedly connected to the inner wall of the box body 1, the second motor 208 is bolted to one side of the transmission pipe 207, the spiral transmission blade 209 is fixedly connected to the output end of the second motor 208, and the spreading pipe 210 is fixedly connected Connected to the bottom of the box body 1, two shoulder straps 211 are arranged on one side of the box body 1, and various fertilizer particles are injected into the partition frame 201 inside the box body 1. The user carries the box body 1 by the shoulder straps 211. Before spreading fertilizer, the first motor 202 can be started to rotate the stirring blades 203, and the fertilizer particles in the partition frame 201 are continuously stirred to accelerate the mixing of various fertilizers. The mixed fertilizer particles will fall onto the guide plate 205 through the leakage hole 204, and the guide plate 205 is tilted to guide the fallen fertilizer particles to the guide pipe 206, and finally enter the transmission pipe 207. The second motor 208 is started to rotate the spiral transmission blades 209, thereby pushing the fertilizer particles in the transmission pipe 207 into the sowing pipe 210. The user can lower the height of the sowing pipe 210 to make the fertilizer particles continue to fall and carry out fertilization.

[0039] like Figure 3As shown, the spraying assembly 3 includes a water tank 301, an extraction pipe 302, a water pump 303 and a spraying pipe 304.

The support column 20 and the support pad 21 are used together to raise the height of the box body 1 to prevent the bottom of the box body 1 from squeezing the sowing tube 210 when the box body 1 is lowered.

[0048] Specifically, when the backpack fertilizer applicator for agricultural fertilization is in use: various fertilizer particles are injected into the partition frame 201 inside the box body 1 through the injection pipe 15 and the fixed frame 16, and then clean water is injected into the water storage tank 301 through the water inlet pipe 18. The user carries the box body 1 on his back through the shoulder strap 211, pulls the telescopic belt 5, makes the clamping ring 7 clamp on the clamping block 6, makes the telescopic belt 5 fit the user's abdomen, and rotates the rotating column 401 to make the first bevel gear 402 rotate, thereby driving the second bevel gear 404 and the screw rod 403 to rotate, so that the limit plate 405 moves up and down, the leakage hole 204 is blocked, the first motor 202 is started, the stirring blade 203 is rotated, the fertilizer particles in the partition frame 201 are continuously stirred, and the mixing of various fertilizers is accelerated. After the fertilizers are mixed, they can be reversed. The rotating column 401 is rotated to move the limit plate 405 downward, so that the mixed fertilizer particles fall onto the guide plate 205 through the leak hole 204. The guide plate 205 is placed tilted to guide the fallen fertilizer particles into the guide tube 206 and finally into the transmission tube 207. The second motor 208 is started to rotate the spiral transmission blades 209, thereby pushing the fertilizer particles in the transmission tube 207 into the sowing tube 210. The user lowers the height of the sowing tube 210 to allow the fertilizer particles to continue to fall and carry out fertilization. The water pump 303 is started to extract the clean water in the water storage tank 301 from the extraction pipe 302 and spray it out after passing through the spraying pipe 304. The user can hold the spraying pipe 304 and use it in conjunction with the sowing pipe 210 to accelerate the dissolution rate of the fertilizer particles after sowing.
