[0030] like Figure 1 and Figure 7As shown, the blowing mechanism 19 includes a mounting plate 191, a first mounting seat 192, an air duct 193 and a fan 194. The mounting plates 191 are arranged on the front and rear sides of the frame 5, the first mounting seats 192 are arranged on the mounting plates 191, the front and rear sides of the discharge pipe position at the lower part of the distribution hopper 7 are connected through the air duct 193, the first mounting seats 192 are arranged on the fans 194, and the air outlet of the fan 194 is connected to the air duct 193.

[0031] like Figure 1 and Figure 6 and Figure 7 As shown, the opening and closing mechanism 20 includes a pressure block 201, a guide rod 202, a second guide sleeve 203, a baffle plate 205, an elastic member 206, a connecting frame 207, a baffle plate 208 and a pressure plate 209. The pressure blocks 201 are arranged at intervals on the transmission wheel 164, the lower end of the air duct 193 is provided with a guide rod 202, and the second guide sleeve 203 is slidably arranged in the guide rod 202. Two straight holes 204 are vertically opened on the front and rear side walls of the discharge pipe position at the lower part of the distribution hopper 7, and the front and rear sides of the discharge pipe of the distribution hopper 7 are slidably provided with a baffle plate 205, and the lower part of the baffle plate 205 is provided with a square hole. The baffle plate 205 passes through The cross frame passes through the straight hole 204 and is connected to the second guide sleeve 203. An elastic member 206 is sleeved on the guide rod 202. The elastic member 206 is a compression spring. One end of the elastic member 206 is connected to the second guide sleeve 203, and one end of the elastic member 206 is connected to the bottom of the guide rod 202. A connecting frame 207 is provided on the side away from each other of the two second guide sleeves 203. A baffle plate 208 is provided on the connecting frame 207. An air outlet is provided on the lower side wall of the air duct 193. The baffle plate 208 contacts and cooperates with the air outlet on the side wall of the air duct 193. A pressure plate 209 is provided on the top of the connecting frame 207, and the pressure plate 209 cooperates with the pressure block 201.

[0032] When sowing is required, the staff rotates the screw rod 174, and the screw rod 174 drives the nut 175 to move. The nut 175 drives the arc partition 177 to move through the connecting rod 176, and the first guide sleeve 173 moves in the guide shaft 172 accordingly. The arc partition 177 moves to the inside of the dividing hopper 7 to cover the seed placement holes on the cylindrical barrel 10. Since the two arc partitions 177 are adjusted to move away from or close to each other through the adjustment mechanism 17, the number of placement holes corresponding to the number of seeds to be planted can be retained. The staff first pours the seeds into the loading hopper 6, and then the seeds in the loading hopper 6 fall into the exposed placement holes on the uppermost side of the outer circle of the cylindrical barrel 10, and then drives the diesel engine 14. The diesel engine 14 drives the first rotating shaft 3 to rotate counterclockwise through the first transmission component 15, and the first rotating shaft 3 drives the tilling wheel 4 to rotate counterclockwise, and the tilling wheel 4 drives the first frame 2 and the roller 13 to rotate. During the movement of this device, the tilling wheel 4 initially turns the soil, and the plow 8 will dig a ditch for interval planting. The roller 13 rotates counterclockwise. The needle rotates through the toothed pulley and the toothed belt transmission, thereby realizing the counterclockwise rotation of the rotating roller 162. The rotating roller 162 drives the transmission wheel 164 to rotate counterclockwise through the transmission belt 165. Since the transmission wheel 164 has a large diameter, the transmission wheel 164 drives the cylindrical barrel 10 to rotate slowly counterclockwise through the second rotating shaft 9, thereby driving the seeds to rotate counterclockwise. When the empty placement hole of the cylindrical barrel 10 is located directly above, the seeds in the loading hopper 6 will fill the empty placement hole of the cylindrical barrel 10. The second rotating shaft 9 is driven by the pulley 184 and the flat belt 185, and then the third rotating shaft 181 rotates. The two gears 183 on the third rotating shaft 181 are meshed for transmission, and then the toggle wheel 182 on the third rotating shaft 181 can rotate with each other, and the excess seeds are toggled to both sides, which is beneficial to the rolling of the cylindrical barrel 10. At the same time, the fan 194 is started, and the fan 194 blows gas into the air duct 193, and the gas is discharged through the gas outlet on the lower side wall of the air duct 193. When the cylindrical tube 10 drives the seeds to fall to the discharge pipe of the distribution hopper 7, the transmission wheel 164 drives the pressure block 201 to squeeze the pressure plate 209, and the pressure plate 209 drives the shielding plate 208 and the second guide sleeve 203 to move downward through the connecting frame 207. The elastic member 206 is compressed, and then the shielding plate 208 blocks the gas outlet on the lower side wall of the air duct 193, and the second guide sleeve 203 drives the baffle plate 205 to move downward. The square hole of the baffle plate 205 is aligned with the outlet of the air duct 193. At this time, the wind blown by the fan 194 enters the discharge pipe of the distribution hopper 7, blowing the seeds downward so that they can be injected into the soil more accurately. When the device continues to move forward, the pressing block 201 does not squeeze the pressing plate 209, and the elastic member 206 drives the second guide sleeve 203 to reset, and then the baffle plate 205 and the shielding plate 208 are reset. When new seeds fall at intervals, the other pressing blocks 201 on the transmission wheel 164 will continue to squeeze the pressing plate 209, repeating the above actions, and the intermittent sowing operation can be completed quickly.

[0033] Embodiment 2, on the basis of embodiment 1, as Figure 8 and Fig. 9 As shown, it also includes a second mounting seat 21, a connecting rod 22, an insert rod 23 and a pouring block 24. The second mounting seat 21 is arranged on the right side wall of the discharge pipe at the lower part of the distribution hopper 7. A vertical rectangular hole is opened on the right side of the second mounting seat 21, and a plug hole is opened horizontally on the second mounting seat 21. The plug holes are spaced apart on the connecting rod 22, and a pouring block 24 is arranged at the bottom of the connecting rod 22. The pouring block 24 passes through the vertical rectangular hole of the second mounting seat 21 through the connecting rod 22, and is inserted into the connecting rod 22 and the plug hole of the second mounting seat 21 through the insert rod 23 to be fixed. When it needs to be used, the height of the connecting rod 22 is adjusted to align it with the plug hole of the second mounting seat 21, and the plug rod 23 is inserted and fixed.

[0034] like Figure 8 As shown, it also includes a medicine liquid tank 25, a mounting sleeve 26, and a liquid spraying pipe 27. The medicine liquid tank 25 is arranged on the top right side of the vehicle frame 1, and the mounting sleeve 26 is arranged on the right side wall position of the discharge pipe at the lower part of the distribution hopper 7. The water pump installed at the bottom of the medicine liquid tank 25 is connected to the liquid spraying pipe 27, and the lower end of the liquid spraying pipe 27 is fixed on the mounting sleeve 26.

[0035] At the same time, since the pouring block 24 is in the shape of an inverted trapezoid, the soil turned up to both sides by the plow 8 can be pushed back and buried. The water pump in the liquid medicine tank 25 works, and then the fertilizer is sprayed onto the soil through the spray pipe 27, which is beneficial to the subsequent seed growth and provides nutrition. The device has a simple structure and can realize rapid soil covering and fertilization operations after sowing.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
