Four transmission frame threaded holes 85 are formed in the transmission support base 81, the size and the position of the transmission frame threaded holes correspond to the four beam threaded holes 76 in the mounting beam 72, and the transmission system support frame 8 is fixed on the hill-drop planter fixing frame 7 through bolt connection; the transmission supporting arm 83 is a bent piece and is in a U shape, and two side walls at the U-shaped opening end are provided with circular through holes 84; a reinforcing rib plate 82 is arranged between the transmission supporting base 81 and the transmission supporting arm 83.
The working process of the invention is as follows:
1) when the hole sowing device works, when the sowing machine moves forwards, the land wheel power chain wheel is connected with the driving chain wheel 13 of the hole sowing transmission system 1 through chain transmission to provide power for the whole hole sowing device. The side of the hole sowing device provided with the seed inlet pipe 23 is the advancing direction. A synchronous belt wheel 16 in the hill-drop transmission system 1 is connected with a synchronous belt wheel on a transmission shaft of the corn precision seed-metering device 9 to provide power for the operation of the seed-metering device. The rear valve type corn precision direct-cutting hole sowing device finishes one-time soil-entering sowing and is divided into four stages: the first stage is a hill planter burying stage, the second stage is a burying seeding stage, the third stage is a seeding valve closing stage, and the fourth stage is a hill planter resetting stage.
2) The soil-entering stage of the hill-drop planter: in the advancing process of the seeder, the first seed discharged by the corn precision seed-metering device 9 falls into the cavity of the dibbler steel pipe 28 of the dibbler 2 through the dibbler seed-feeding pipe 23, finally falls into the lowest end of the seed-metering inclined plane 27 and is blocked in the cavity of the dibbler 2 by the back valve seed-blocking plate 44. At this time, the hill-drop drill 2 moves downward along with the push stroke curve movement section of the cam contour surface 11 on the cam shaft 12 in the hill-drop transmission system 1 under the combined action of the cam contact plate 22, the large compression spring 55 and the upper guide seat 5 until the valve guide sleeve limiting plate 35 just contacts the rear valve limiting plate 61, and the soil entering inclined surface 29 at the lower end of the hill-drop drill 2 enters the soil, which is the first stage in the one-time reciprocating movement process of the hill-drop drill.
3) A soil-entering seeding stage: after the valve guide sleeve limiting plate 35 contacts the rear valve limiting plate 61, the hole sowing reciprocating device 2 continues to move downwards, due to the blocking of the rear valve limiting plate 61, the valve 4 moves upwards relative to the hole sowing reciprocating device 2 along the seeding valve guide post 32 under the driving of the cylinder 36 after seeding, the valve 4 is opened after seeding, seeds slide downwards along the seeding inclined plane 27 and are discharged into a seed hole, when the hole sowing reciprocating device 2 moves to the lower end limit position, the uncut seamless steel pipe section 41 on the valve 4 after seeding blocks a connecting port between the hole sowing device seed inlet pipe 23 and a main steel pipe of the hole sowing reciprocating device 2, so that a second seed is prevented from entering a cavity of the hole sowing reciprocating device when falling down in designated time, and the second stage is the second stage in the one-time reciprocating motion process of the hole sowing device.
4) Closing the seed discharging valve: after the hole sowing reciprocating device 2 moves to the lowest limit point, the cam shaft 12 is in contact with the cam contact plate 22 in the return curve stage of the cam profile surface 11 after rotating, and the hole sowing reciprocating device 2 starts to move upwards under the combined action of the cam contact plate 22, the large pressure spring 55 and the upper guide seat 5; under the combined action of the seed valve guide post 32, the small pressure spring 33 and the seed valve guide post guide plate 24, the valve 4 starts to be closed after seed sowing under the action of the spring force, and when the valve guide sleeve limiting plate 35 just leaves the rear valve limiting plate 61, the valve 4 is completely closed after seed sowing. This is the third stage in one reciprocation of the bunch planting device.
5) Resetting the hill planter: when the valve guide sleeve limiting plate 35 leaves the rear valve limiting plate 61, the hole sowing reciprocating device 2 continues to move upwards under the combined action of the cam contact plate 22, the large pressure spring 55 and the upper guide seat 5 until the initial position is returned. This is the fourth stage in one reciprocation of the bunch planting device.
6) In the working process, the upper guide seat 5 and the soil removal guide seat 6 play a role in guiding the hole sowing reciprocating device 2; the lower soil removing curved surface 65 arranged on the soil removing guide seat 6 plays a role in removing soil from soil which may be adhered to the pipe wall after the hole sowing reciprocating device 2 enters the soil and in the process of soil discharging; the sharp-angled joint formed by the soil-entering inclined plane 29 at the lower end of the hole sowing reciprocating device 2 and the tube wall of the hole sowing device main body plays a role in poking films and entering soil in the sowing process.
In the above embodiment, the valve 4 after seed metering can be cut by a whole section of seamless steel pipe.
In the above embodiment, the lower guiding fixed sleeve 62 and the lower dibbler soil removing guiding sleeve 64 in the soil removing guiding seat 6 can be manufactured by a process of casting and then lathing.
In the above embodiment, the lower soil removing curved surface 65 and the outer surface of the steel pipe of the main body of the hole sowing reciprocating device 2 are coated with the coating for reducing the friction coefficient so as to reduce the cohesive force between the soil and the soil in the soil entering process.
