[0024] Embodiment 1

[0025] Embodiment: Refer to Figure 1-Figure 5 a fertilizing device for millet planting shown in the figure, including a vehicle frame 1, a feed pipe 2, a fertilizer tank, a rotating shaft 4 and a driving motor. An avoidance hole adapted to the feed pipe 2 is opened at the top of the vehicle frame 1. A baffle 13 is arranged below the vehicle frame 1, and a driving mechanism for moving the baffle 13 is arranged on the vehicle frame 1;

[0026] The driving mechanism includes three circular plates 11 arranged above the frame 1, a sliding hole is provided on the top of the frame 1, two sliding rods are installed on the opposite inner walls of the sliding hole, a slider 12 is slidably sleeved on the two sliding rods, an elastic unit is provided on the side of the slider 12, a baffle 13 is installed on the side of the slider 12, a storage hole is provided at the bottom of the baffle 13, an L-shaped fixing block 29 is installed at the bottom of the frame 1, a unloading hole is provided at the bottom of the L-shaped fixing block 29, the slider 12 is installed in cooperation with the circular plate 11 through a pulling unit, and a driven unit that enables the three circular plates 11 to rotate at different speeds is provided on the frame 1, and the driven unit is installed in cooperation with the rotating shaft 4.

[0027] By means of the above structure, when in use, the frame 1 is first moved, at which time the fertilizer will fall into the storage hole on the baffle 13 and be blocked by the L-shaped fixed block 29, and then the drive motor is started, the output of the drive motor will cause the rotating shaft 4 to rotate, and the rotation of the rotating shaft 4 will cause the three circular plates 11 to rotate to different degrees through the driven unit, and the rotation of one of the circular plates 11 will cause the slider 12 to move through the pulling unit, and the movement of the slider 12 will cause the baffle 13 to move with the cooperation of the slide rod, when the storage hole is in contact with the discharge hole, the fertilizer falls under the action of gravity, and when it is necessary to change the fertilizer falling interval, the pulling unit is installed on another circular plate 11, and at this time, the rotation speed of the circular plate 11 slows down or speeds up, which will cause the slider 12 to move faster or slower, thereby making the movement time of the baffle 13 longer or shorter, so that the fertilization spacing can be adjusted without adjusting the speed of the motor, and the scope of application is wider and it is easy to use.

[0028] Example 2

[0029] like Figure 5 As shown, the driven unit includes three first bevel gears 5 sleeved on the rotating shaft 4, a circular frame 6 is installed on the top of the frame 1, and three movable holes are opened on the side of the circular frame 6, and movable rods 7 are rotatably sleeved on the three movable holes, and three circular plates 11 are respectively installed on the ends of the three movable rods 7, and the other ends of the three movable rods 7 are respectively installed with second bevel gears 8, third bevel gears 9 and fourth bevel gears 10, which are respectively meshed with the two first bevel gears 5, and the diameters of the second bevel gears 8, third bevel gears 9 and fourth bevel gears 10 are successively reduced and are larger than the first bevel gear 5. The advantage of such an arrangement is that the circular plate 11 is easily rotated by the arrangement of the first bevel gear 5, the circular frame 6, the movable rod 7, the second bevel gear 8, the third bevel gear 9 and the fourth bevel gear 10.

[0030] Specifically, the rotation of the rotating shaft 4 will cause the first bevel gear 5 to rotate, and the first bevel gear 5 will cause the second bevel gear 8, the third bevel gear 9 and the fourth bevel gear 10 to rotate. Since the diameters of the second bevel gear 8, the third bevel gear 9 and the fourth bevel gear 10 are different, the second bevel gear 8, the third bevel gear 9 and the fourth bevel gear 10 rotate at different speeds. The rotation of the second bevel gear 8, the third bevel gear 9 and the fourth bevel gear 10 will cause the three circular plates 11 to rotate to different degrees through the movable rod 7, thereby lengthening or shortening the movement time of the baffle 13, so that the fertilization spacing can be adjusted without adjusting the speed of the motor, which has a wider range of application and is easy to use.

[0031] like Figure 2 As shown, the pulling unit includes a U-shaped block 14 installed on the top of the slider 12, a reeling rod 15 is rotatably installed on the relative inner wall of the U-shaped block 14, a knob is installed on one end of the reeling rod 15, a fixing threaded hole is provided on the top of the U-shaped block 14, a second bolt 20 is threadedly installed on the fixing threaded hole, the end of the second bolt 20 is tightly abutted against the reeling rod 15, a pull rope 16 is reeled on the reeling rod 15, and mounting grooves are provided on the sides of the three circular plates 11, a moving block 17 is movably provided in one of the mounting grooves, and the moving block A rotating rod 18 is rotatably installed on the side of 17, and the other end of the pull rope 16 is installed on the rotating rod 18. Limit threaded holes are provided on the sides of the three circular plates 11, and a first bolt 19 is movably installed on one of the limit threaded holes. The end of the first bolt 19 is tightly abutted against the moving block 17. The advantage of such an arrangement is that through the arrangement of the U-shaped block 14, the winding rod 15, the pull rope 16, the moving block 17, the rotating rod 18, the first bolt 19 and the second bolt 20, it is convenient to make the slider 12 cooperate with different circular plates 11.

[0032] Specifically, when in use, the moving block 17 is first installed on one of the circular plates 11 through the first bolt 19, and then the winding roller 15 is rotated through the knob. The rotation of the winding roller 15 will tighten the pull rope 16, and then it is fixed by the second bolt 20. When fixed, the circular plate 11 is rotated, and the rotation of the circular plate 11 will cause the moving block 17 to move eccentrically. The eccentric movement of the moving block 17 will pull the pull rope 16 through the rotating rod 18, thereby moving the slider 12 to perform fertilization operations.

[0033] like Figure 4 As shown, the elastic unit includes a spring 21 installed on the side of the slider 12, and the other end of the spring 21 is installed on the inner wall of the side of the sliding hole.

The advantage of such an arrangement is that, through the arrangement of the support plate, the axle 22, the wheel, the driven rod 23, the reciprocating threaded guide sleeve, the threaded block 24, the T-shaped scraper 25, the first sprocket 26 and the second sprocket 27, the chain 28 and the guide rod, it is convenient to cover the ditch after fertilization with soil.

[0036] Specifically, when the frame 1 moves, the wheels rotate, and the rotation of the wheels will cause the axle 22 to rotate. The rotation of the axle 22 will cause the driven rod 23 to rotate rapidly through the first sprocket 26, the second sprocket 27 and the chain 28. The rapid rotation of the rod 23 will cause the T-shaped scraper 25 to move back and forth through the reciprocating threaded guide sleeve and the threaded block 24, thereby pushing the soil to the middle, thereby covering the ditch with soil for easy use.
