And a sealing block 3n correspondingly matched with the slot is also arranged at one end part of the pore plate 3 b. When the other end of the hole plate 3b is inserted into the bottom of the slot, one end of the sealing block 3n is tightly attached to the side wall of the seed suction box 3a to play a role in sealing.
One suction nozzle 3d is connected to each hole of the orifice plate 3 b. The upper end of the suction nozzle 3d is provided with connecting threads matched with the hole, the suction nozzle 3d is provided with air holes 3j which are coaxially distributed, the upper end of each air hole 3j is inserted into the cavity of the seed suction box 3a and communicated with the cavity, the lower end of each air hole 3j is provided with a small hole section 3c, and the lower end of each small hole section 3c is communicated with a horn mouth 3 m. The upper end of the small hole section 3c is provided with a conical expansion part communicated with the air hole 3 j. The air flow flowing out of the small hole section can be enabled through the conical expansion part, the design of the small hole section can improve the air flow velocity at the bell mouth, the suction at the bell mouth is ensured, and the condition that the seed is clamped on the air hole and cannot fall down can be avoided through the design of the bell mouth.
However, a plurality of hole plates 3b with different hole pitches are provided to cope with the sowing of seeds with different densities.
The upper end of the seed suction box 3a is provided with a bronchus 3k, the two ends of the bronchus 3k are communicated with the cavity in the seed suction box 3a, the body of the bronchus 3k is also communicated with a gas pipe 3e, and the upper end of the seed suction box 3a on one side of the gas pipe 3e is also welded with a handle 3 h. So that the worker can hold the handle to pull the seed suction box 3a to move back and forth on the carriage 2.
A negative pressure fan 6 is arranged at the bottom of the frame 1, and one end of the air pipe 3e is communicated with the negative pressure fan 6. The air pipe 3e and the negative pressure fan 6 are provided with air pipe allowance with certain length so that the seed suction box 3a can be provided with stretching allowance for the air pipe 3e when the sliding frame 2 moves, and the air pipe 3e is prevented from loosening from the bronchus 3 k.
Switches (not shown in the figure) corresponding to the seed suction device 3 are arranged on the first limit block 7 and the second limit block 7a, and the switches and the negative pressure fan 6 form a switch matched with an electric signal connection. The switch is a touch switch.
And the seed throwing device 4 is correspondingly matched with the seed sucking device 3 on the machine frame 1 below the side of the first limiting block 7. The seed throwing device 4 comprises a seed throwing disc 4a, and a group of springs 4b which are connected and matched with the rack 1 are uniformly distributed on the seed throwing disc 4 a. An electromagnet 4c is arranged at the bottom of the seed throwing disc 4a, a guide groove 4e correspondingly matched with the electromagnet 4c is further arranged on the machine frame 1, and a permanent magnet 4d corresponding to the electromagnet 4c is arranged at the bottom of the guide groove 4 e. The electromagnet 4c is communicated with a mains supply through a lead not shown in the figure, and an electrifying switch is further arranged on the lead and forms linkage fit with a switch on the first limiting block 7. The seed throwing disk 4a is also provided with a vent hole (not shown) smaller than the seed.
A seed tray 5 is also arranged on the rack 1 at one side of the seed throwing device 4, a grid plate 5a is arranged in the seed box 3a, the space in the seed tray 5 is divided into a group of independent spaces which are not communicated with each other through the grid plate 5a, and the spaces correspond to the suction nozzles 3d, so that seeds sucked up by the suction nozzles 3d fall into the corresponding independent spaces in the seed tray.
But a plurality of grid plates with different sizes can be arranged to deal with the sowing of seeds with different densities.
The working process is as follows:
according to the required seeding density, a pore plate with a proper hole pitch and a grid plate with a corresponding size are selected, the pore plate is inserted on the seed suction box, then the suction nozzle is connected on the pore plate through threads, and then the grid plate is placed in the seed tray. Then the seeds to be sowed are placed into a seed throwing plate.
When a worker holds the handle to move the seed suction box, the seed suction box is made to impact a switch on the first limiting block, and the switch is linked with a starting switch of the negative pressure fan and an electrifying switch on the electromagnet lead. The negative pressure fan is started to form negative pressure in the seed suction box, meanwhile, the electromagnet is electrified by the electrifying switch, so that the electromagnet and the permanent magnet are quickly attracted together, the seeds in the seed throwing plate are in a suspended free state under the action of inertia and are caught by the suction nozzle, and the lower end of the horn-mouth-shaped suction nozzle enables the seeds to be caught by the suction nozzle and the rear part of the seeds can be clamped in the lower end of the suction nozzle.
When the worker holds the handle, the seed suction box is moved to the second limiting block, the seed suction box is separated from the switch on the first limiting block, the electromagnet is powered on, the switch is powered off, and the seed throwing disc is reset under the action of the spring. When the seed suction box impacts a switch on the second limiting block, a shutdown switch of the negative pressure fan is started, the startup switch jumps up, the negative pressure fan stops working, and seeds positioned at the lower end of the bell-mouth-shaped suction nozzle lose the suction of negative pressure and fall into a corresponding independent space in a seed tray below.
