At the same time, a group of blades on the soil-breaking cone cuts the soil blocks, and the blades are adjusted according to the dryness and wetness of the soil blocks. If the soil blocks are drier, the blades are tilted and the soil-breaking cone plays a main crushing role. If the soil blocks are wetter, the blades are horizontal and the blades play a main crushing role, and the soil-breaking cone plays an auxiliary crushing role. After the blades cut the soil blocks into pieces, the hydraulic push rod is controlled to operate. The hydraulic push rod drives the movable plate to move slightly left and right under the support of the sliding sleeve and the sliding rod, and the soil-breaking position of the soil-breaking cone and the blades is adjusted to improve the crushing rate of the soil blocks.

[0019] Third, the present invention provides a mounting seat, a rotating plate, a sector block, a feed pipe, a gooseneck tube and an adjusting block.

The empty grooves between the plurality of sector block groups are weighing grooves for transporting fertilizers or seeds. The larger the area of ​​the sector block group, the smaller the area of ​​the empty groove, and the less the amount of material discharged. After the rotating plate is adjusted, the magnetic block at the bottom of the mounting seat is inserted into In the second magnetic suction groove at the bottom end of the fixed seat, and the supporting shaft on the rotating plate is movably connected with the fixed seat, the mounting seat is engaged with the fixed seat, and then the mounting seat is fixedly connected with the fixed seat by a lock.

After it is filled with fertilizer or seeds, it completely enters the circular groove to achieve sealing. When the empty groove rotates to one side of the discharge trough, the fertilizer or seeds enter the gooseneck tube through the discharge trough, and finally flow out through the gooseneck tube and fall into the foundation pit, realizing the timed and quantitative discharge of fertilizer or seeds.

When the loosening tool holder 10 rotates, the soil is excavated and rotated out through the folded tool to achieve loosening. While loosening the soil, the electric push rod 1206 is controlled to operate, and the electric push rod 1206 drives the pressing plate 1207 and the multiple soil breaking cones 1208 to move downward. The soil breaking cones 120 8 to break the turned-over soil blocks, and at the same time a group of blades 1209 on the soil-breaking cone 1208 cut the soil blocks, and the blades 1209 are adjusted according to the dryness and wetness of the soil blocks. If the soil blocks are dry, the blades 1209 are tilted, and the soil-breaking cone 1208 plays a main crushing role. If the soil blocks are wet, the blades 1209 are horizontal, and the blades 1209 play a main crushing role, and the soil-breaking cone 1208 plays an auxiliary crushing role. After the blades 1209 cut the soil blocks, the hydraulic push rod 1202 is controlled to operate. The hydraulic push rod 1202 drives the movable plate 1203 to move slightly left and right under the support of the sliding sleeve 1204 and the sliding rod 1205, and the soil-breaking position of the soil-breaking cone 1208 and the blades 1209 is adjusted to perform secondary soil breaking, which can improve the crushing rate of the soil blocks. After the soil blocks are broken,If it is necessary to fertilize or sow in the foundation pit, the fertilizer barrel or seed barrel is connected to the feed pipe 1301, so that the fertilizer or seeds can enter the feed groove 1302 inside the fixed seat 1303 through the feed pipe 1301, and the area and number of the fan-shaped blocks 1310 on the rotating plate 1308 are adjusted in advance according to the amount of fertilizer or sowing, and the mounting seat 1304 is fixedly connected to the fixed seat 1303 through the lock 1306. After fixing, the second motor 1307 is controlled to run, and the second motor 1307 drives the output end The rotating plate 1308 and the multiple groups of fan-shaped blocks 1310 rotate, so that the empty slot rotates to the bottom of the feeding slot 1312, and the fertilizer or seeds enter the empty slot, and the empty slot rotates continuously. After the inside is filled with fertilizer or seeds, it completely enters the circular slot to achieve sealing. When the empty slot rotates to one side of the feeding slot 1312, the fertilizer or seeds enter the gooseneck tube 1313 through the feeding slot 1312, and finally flow out through the gooseneck tube 1313 and fall into the foundation pit, realizing the timing and quantitative feeding of fertilizer or seeds.
