When the fourth bevel gear 340 rotates, it drives the corresponding third bevel gear 230 and screw 240 to rotate. When the screw 240 rotates, the fertilizer is sent from the upper fertilizer hopper 111 to the lower part. In the fertilizer hopper 114, since the pitch of the screw 240 is fixed, the amount of fertilizer delivered to the lower part per each rotation of the screw 240 is fixed, and thus the amount of fertilizer delivered can be adjusted by adjusting the rotation speed of the screw 240. Due to the stirring and crushing of the stirring teeth 330, the fertilizer in the upper fertilizer hopper 111 can flow evenly into the first fertilizer outlet 113, so that the amount of fertilizer delivered by the device can be accurately controlled. The detachable stirring device 300 and the screw 240 can also ensure that when the screw 240 is stuck, it can be quickly cleaned, thereby improving the fertilization efficiency.

[0026] refer to Figure 6The outer side of the fertilizer outlet 115 is fixedly connected to a material guide cover 140, which is a quarter circle. The material guide cover 140 and the fertilizer outlet 115 are connected to form a fertilizer outlet with an opening facing downward. When the No. 1 motor 190 rotates, it drives the No. 1 shaft 180 to rotate, and the No. 1 shaft 180 drives a group of No. 1 bevel gears 210 to rotate. The No. 1 bevel gears 210 drive their respective No. 2 bevel gears 220 to rotate, and the No. 2 bevel gears 220 drive their respective fertilizer-throwing plates 130 to rotate. When the fertilizer-throwing plates 130 rotate, the fertilizer is thrown away. A group of fertilizer-throwing plates 130 ensures that the fertilizer can be fully thrown away and mixed. The thrown away fertilizer enters the guide cover 140 from the fertilizer discharge port 115. The quarter-circular guide cover 140 allows the fertilizer to be evenly mixed again during the collision between the thrown away fertilizer and the inner wall of the guide cover 140. The fertilizer flows out from the guide covers 140 on both sides. When spreading fertilizer, the farmland is sprayed twice, ensuring that the fertilizer is evenly spread in the farmland.

[0027] refer to Figures 3 to 7 Two symmetrical side slide grooves 117 are respectively provided on both sides of the frame 110, and a fertilizer receiving plate 150 is provided in the side slide groove 117 on each side.

[0028] A group of funnels 151 are evenly arranged in the middle of the fertilizer receiving plate 150, and a second fertilizer leaking port 152 is arranged at the lower part of each funnel 151. When the lead screw 170 rotates, the fertilizer receiving plates 150 on both sides are driven to move away from the frame 110 or approach the frame 110 at the same time. When the fertilizer receiving plates 150 on both sides are close to the fertilizer receiving plates 150, the fertilizer receiving plates 150 on both sides and the outlets of the upper material guide cover 140 are closed, and the fertilizer in the material guide cover 140 falls into the fertilizer receiving plates 150. When the fertilizer receiving plates 150 on both sides are away from the frame 110, the fertilizer receiving plates 150 and the outlets of the material guide cover 140 are staggered, and the fertilizer in the material guide cover 140 is spread in the field. The above structure enables the device to realize both ground fertilization and underground fertilization.

[0029] Reference Image Figure 8 The frame 110 is provided with front and rear slide grooves 121 on both sides, and each front and rear slide groove 121 is provided with a group of fertilizer rods 160.

When the fertilizer rod 160 moves forward with the device, the plow 161 plows a groove on the ground, and the fertilizer in the fertilizer pipe 162 flows into the ground from the fertilizer pipe 162. A group of funnels 151 can ensure that the fertilizer can flow into each funnel 151 evenly, so as to ensure the uniformity of the fertilizer.

[0031] A method for operating a land protection and reclamation mechanical device. When the device is used, the device is connected to a motor vehicle. When fertilizing the land protection and reclamation, the fertilizer is put into the upper fertilizer bucket 111. When the device moves forward, the second motor 350 and the first motor 190 are started. When the second motor 350 rotates, the second shaft 310 is driven to rotate. The second shaft 310 drives the stirring gear 330 and the fourth bevel gear 340 to rotate. When the stirring gear 330 rotates, the fertilizer in the frame 110 is evenly stirred and the fertilizer is evenly mixed. The lumps in the fertilizer are broken up so that the fertilizer can be evenly distributed in the upper fertilizer hopper 111 and flow into each first fertilizer outlet 113. When the fourth bevel gear 340 rotates, it drives the corresponding third bevel gear 230 and the screw 240 to rotate. When the screw 240 rotates, the fertilizer is sent from the upper fertilizer hopper 111 to the lower fertilizer hopper 114 at the bottom. When the first motor 190 rotates, it drives the first shaft 180 to rotate. The first shaft 180 drives a group of first bevel gears 210 to rotate. The bevel gear 210 drives the respective second bevel gear 220 to rotate, and the second bevel gear 220 drives the respective fertilizer-throwing plate 130 to rotate. When the fertilizer-throwing plate 130 rotates, the fertilizer is thrown away. A set of screws 240 ensures that the fertilizer can be fully thrown away and mixed. The thrown away fertilizer enters the guide cover 140 from the fertilizer discharge port 115. When spreading fertilizer on the ground, the fertilizer receiving plates 150 on both sides and the outlets of the fertilizer receiving plates 150 are staggered, and the fertilizer sprinkled from the guide cover 140 is evenly sprayed on the field. When applying fertilizer, the fertilizer receiving plates 150 on both sides and the outlets of the upper material guide cover 140 are closed, and the fertilizer in the material guide cover 140 falls into the fertilizer receiving plate 150. The fertilizer falling into the fertilizer receiving plate 150 falls from each funnel 151 and flows out from the second fertilizer leakage port 152. The outflowing fertilizer flows into the lower fertilizer pipe 162 through the hose 250. When the fertilization rod 160 moves forward with the device, the plow 161 plows a groove on the ground, and the fertilizer in the lower fertilizer pipe 162 flows into the ground from the lower fertilizer pipe 162.

[0032] During land protection and reclamation fertilization, since the pitch of the screw 240 is fixed, the amount of fertilizer delivered to the lower part per rotation of the screw 240 is fixed, so the amount of fertilizer delivered can be adjusted by adjusting the rotation speed of the screw 240. Due to the stirring and crushing of the stirring teeth 330, the fertilizer in the upper fertilizer hopper 111 can flow evenly into the first fertilizer outlet 113, so that the amount of fertilizer delivered by the device can be accurately controlled. The detachable stirring device 300 and the screw 240 can also ensure that the screw 240 can be quickly cleaned when it is stuck, thereby improving the fertilization efficiency. A set of screws 240 ensures that the fertilizer can be fully shaken off and mixed, and the fertilizer after shaking off is discharged from the discharge The fertilizer port 115 enters the material guide cover 140. The quarter-circular material guide cover 140 allows the fertilizer to be evenly mixed again during the collision between the fertilizer and the inner wall of the material guide cover 140 after being thrown away. The fertilizer flows out from the material guide covers 140 on both sides. When spreading fertilizer, the farmland is sprayed twice, ensuring that the fertilizer is evenly spread on the farmland. A group of funnels 151 can ensure that the fertilizer can flow into each funnel 151 evenly to ensure the uniformity of the fertilizer. The two fertilizer receiving plates 150 slidably connected to the frame 110 and the material guide covers 140 on both sides cooperate with each other to realize the conversion between ground fertilization and underground fertilization, so that the device can take into account both ground fertilization and underground fertilization, which is beneficial to land protection and reclamation.
