[0020] like Figure 1 As shown, the utility model provides an agricultural machinery sowing device, including a sowing box 1, an opening is provided on the upper side of the sowing box 1, elastic support members 2 are connected to the two side walls inside the sowing box 1, and a filter plate 3 is connected to the upper sides of the two elastic support members 2. The elastic support member 2 includes a connecting plate 2.1, the connecting plate 2.1 is connected to the inner wall of the sowing box 1, a plug hole is provided on the connecting plate 2.1, a support rod 2.2 is plugged into the plug hole, the filter plate 3 is connected to the upper side of the support rod 2.2, and a spring 2.3 is also connected between the filter plate 3 and the connecting plate 2.1, the spring 2.3 is sleeved on the outer side of the support rod 2.2, and the filter plate 3 is elastically supported by the two springs 2.3.

[0021] A driving device is also connected to the seeding box 1, and the driving device is used to drive the filter plate 3 to move up and down. The driving device is a second motor, and the second motor is connected to the outside of the seeding box 1. A through hole is provided on the side wall of the seeding box 1, and the output shaft of the second motor passes through the through hole. A cam 11 is connected to the output shaft of the second motor, and the cam 11 is arranged in the seeding box 1. The cam 11 is in contact with the filter plate 3, and the cam 11 is driven by the second motor to rotate. During the rotation of the cam 11, the filter plate 3 is lifted upward, and then under the elastic force of the spring 2.3 and the gravity of the filter plate 3, the filter plate 3 moves downward. Therefore, the rotation of the cam 11 drives the filter plate 3 to move up and down, speeding up the filtering of the seeds by the filter plate 3. The filtered seeds fall to the bottom of the seeding box 1, and the large particles of impurities in the seeds are screened out by the filter plate 3 and remain on the filter plate 3.

[0022] A group of discharge boxes 4 are connected to the lower side of the sowing box 1. In this embodiment, the number of the discharge boxes 4 is three. The discharge boxes 4 are connected to the sowing box 1. An outlet pipe 4.1 is connected below each discharge box 4 to discharge seeds through the outlet pipe 4.1.

[0023] Through holes are provided on both side walls of each discharge box 4, and a discharge member 5 is inserted between the two through holes. Figure 2 As shown, the discharge member 5 includes a first cylinder 5.1, which is inserted into the through hole of each discharge box 4, and the diameter of the first cylinder 5.1 is the same as the inner diameter of the through hole of the discharge box 4. A second cylinder 5.3 is connected to one side of the first cylinder 5.1, and a group of fan blades 5.2 are evenly distributed on the second cylinder 5.3. By rotating the fan blades 5.2, uniform sowing and fertilization can be carried out, and when the discharge member 5 is moved, the larger the internal space of the discharge box 4 occupied by the first cylinder 5.1, the less material it discharges, and when the fan blades 5.2 occupy the larger internal space of the discharge box 4, the more material it discharges.

[0024] All the discharging members 5 are connected by a rotating shaft 6, that is, the rotation of the rotating shaft 6 can drive all the discharging members 5 to rotate, thereby driving the seeds to be discharged from the outlet pipe 4.1.

[0025] One end of the rotating shaft 6 is connected to a screw rod 8 via a rotating connecting member 7. Figure 3 As shown, the rotating connection member 7 includes a circular tube 7.1, and limit plates 7.2 are connected to the openings on both sides of the circular tube 7.1.

Through the rotating connection member 7, the rotating shaft 6 can be moved with the screw 8 while rotating.

[0026] A fixing plate 1.1 is connected to the lower side of the seeding box 1 near the screw 8, and a threaded through hole is provided on the fixing plate 1.1, in which the screw 8 is threadedly connected, and a hexagonal plate is connected to the outer end of the screw 8, and the screw 8 is driven to rotate by rotating the hexagonal plate, and the screw 8 and the threaded through hole on the fixing plate 1.1 are threadedly transmitted, so that the screw 8 can drive the rotating connecting member 7 to move, and the rotating connecting member 7 drives the rotating shaft 6 to move, and the rotating shaft 6 drives the three discharging members 5 to move in the discharging box 4, that is, the amount of discharge of the three discharging boxes 4 can be adjusted by rotating the screw 8.

[0027] The screw rod 8 is also threadedly connected with a locking nut 8.1. After the amount of material discharge is adjusted, the locking nut 8.1 is tightened to fix the screw rod 8 to prevent the screw rod 8 from rotating.

[0028] A sliding groove is provided on the other end face of the rotating shaft 6, and the sliding groove is a rectangular groove. A square shaft 9 is inserted in the sliding groove. The square shaft 9 is inserted in the sliding groove, so that the rotating shaft 6 can move left and right while rotating. A mounting plate is connected to the lower side of the seed box 1, and a first motor 10 is connected to the mounting plate. The output shaft of the first motor 10 is connected to the square shaft 9. The square shaft 9 is driven to rotate by the first motor 10, and the square shaft 9 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the three discharge members 5 to rotate, thereby realizing the discharge of the discharge box 5.

[0029] The device is provided with three discharging boxes 4, so that the sowing box 1 can sow three rows of seeds in one movement, thereby improving the sowing efficiency. Moreover, the three discharging members 5 can be driven by the screw 8 to adjust the amount of seed discharge of the multiple discharging boxes 4.
