Both ends of the mounting plate 21 are slidably mounted in a sliding groove I opened on the inner wall of the frame 1, the middle part of the rotating disk 25 is mounted on the mounting plate 21 through a bearing, and is transmission-connected to the driving motor I 26 installed on the mounting plate 21, and one end of the connecting rod 23 is hinged to the side of the rotating disk 25. The other end is hinged on the upper end of the slide bar 24, the slide bar 24 is slidably installed in the sliding sleeve arranged on the mounting plate 21, and the hole-opening hammer 22 is installed at the lower end of the slide bar 24; the lifting mechanism is installed on the frame 1 and is transmission-connected with both ends of the mounting plate 21; the ditching mechanism 3 includes a ditching plate 31, a fixed plate 32, a screw rod 33, and a drive motor II 34, both ends of the fixed plate 32 are slidably installed in the slide groove II opened on the inner wall of the frame 1, the screw rod 33 is vertically installed on the frame 1 and is threadedly connected with the fixed plate 32, and the upper end is transmission-connected with the drive motor II 34 installed on the frame 1, and the ditching plate 31 is installed at the bottom of the fixed plate 32. During hole sowing, the driving motor I 26 drives the turntable 25 to rotate, and the turntable 25 drives the upper end of the connecting rod 23 to rotate, thereby pulling the sliding rod 24 to move up and down in the sliding sleeve, thereby driving the hole-opening hammer 22 to open holes in the ground. As the seeder moves forward, holes are continuously opened on the ground, and the seed-dispensing device 4 discharges the broad bean seeds into the hole pond; during row sowing, the hole-opening hammer 22 is lifted upward by the lifting mechanism, and then the driving motor II 34 is started to drive the screw rod 33 to rotate, so that the fixed plate 32 drives the furrowing plate 31 at the bottom to move downward and insert into the soil. As the seeder moves forward, a sowing furrow is opened, and the seed-dispensing device 4 discharges the broad bean seeds into the sowing furrow. The utility model can perform both hole sowing and row sowing of broad bean seeds by means of the hole-opening mechanism 2 and the furrowing mechanism 3. When sowing in holes, the furrowing plate 31 is raised by driving the motor II 34, and the hole-opening mechanism 2 is used for hole sowing; when sowing in rows, the hole-opening hammer 22 is lifted upward by the lifting mechanism, and the furrowing plate 31 is used for furrowing, thereby performing row sowing. The hole-opening mechanism 2 and the furrowing mechanism 3 are easy to switch and simple to operate, thereby realizing dual-purpose of one machine, increasing the use range of the seeder, and improving the practicability of sowing.

[0018] The lifting mechanism includes a screw 27, a transmission rod 28, and a double-shaft motor 29. The screw 27 is installed in the slide groove I through a bearing and is threadedly connected to the mounting plate 21. The double-shaft motor 29 is installed on the frame 1. The two output shafts are respectively connected with the transmission rod 28. The transmission rod 28 is connected to the upper end of the screw 27 through a worm gear transmission. The double-shaft motor 29 drives the transmission rod 28 to rotate, and the transmission rod 28 drives the screw 27 to rotate. The screw 27 is threadedly connected to the mounting plate 21, so that the mounting plate 21 drives the hole-opening hammer 22 to rise and fall. When hole-sowing is required, the hole-opening hammer 22 is lowered, and when row-sowing is required, the hole-opening hammer 22 is raised.

[0019] A soil cover plate 5 is installed at the bottom of the frame 1. The cross section of the soil cover plate 5 is V-shaped and a V-shaped notch is opened at the bottom. After the seeding device 4 discharges the broad bean seeds into the pit or sowing furrow, the soil cover plate 5 moves forward with the seeder to scrape the soil on both sides of the pit or sowing furrow toward the middle, thereby covering the pit or sowing furrow. The V-shaped notch can make the soil in the middle pile high.

[0020] The bottom of the seed metering device 4 is connected with a seed metering tube 41. The seed metering device 4 discharges broad bean seeds into a hole or a sowing furrow through the seed metering tube 41.

[0021] The frame 1 is provided with an engine 6 for driving the tires on the frame 1 to move. The engine 6 drives the seeder to move forward, thereby improving the efficiency of broad bean sowing.

[0022] The frame 1 is provided with a handrail for controlling the forward direction of the sowing machine. The forward direction of the sowing machine can be controlled by the handrail so that the broad bean sowing can be standardized and orderly.

[0023] Working process:

[0024] During hole sowing, the driving motor I 26 drives the rotating disk 25 to rotate, and the rotating disk 25 drives the upper end of the connecting rod 23 to rotate, thereby pulling the sliding rod 24 to move up and down in the sliding sleeve, thereby driving the hole-opening hammer 22 to open holes in the ground. As the seeder moves forward, holes are continuously opened on the ground, and the seed-dispensing device 4 discharges broad bean seeds into the hole pond, and the covering plate 5 moves forward with the seeder to scrape the soil on both sides of the hole pond into the middle of the hole pond to cover the seeds; during row sowing, the hole-opening hammer 22 is lifted upward by the lifting mechanism, and then the driving motor II 34 is started to drive the screw rod 33 to rotate, so that the fixed plate 32 drives the furrowing plate 31 at the bottom to move downward and insert into the soil. As the seeder moves forward, a sowing furrow is opened, and the seed-dispensing device 4 discharges broad bean seeds into the sowing furrow, and the covering plate 5 moves forward with the seeder to scrape the soil on both sides of the sowing furrow into the middle of the sowing furrow to cover the seeds, thereby completing sowing.
