[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the turntable 30 is in the shape of a disk, the baffle 31 is in the shape of a semicircular plate, the outer arc size of the baffle 31 is half of the circular side wall of the turntable 30, the bottom of the partition plate 22 is an arc-shaped pit recessed upward, the arc-shaped pit at the bottom of the partition plate 22 is adapted to the arc surface at the top of the baffle 31, the turntable 30 can pass through the wall of the loading box 20 on the other side wall opposite to the baffle 31 and be connected to the output end of the rotating motor 24, the fixing plate 33 is symmetrically arranged on the wall of the turntable 30 below the baffle 31, and the side wall of the symmetrical fixing plate 33 is V-shaped. The top of the single room bottom 23 is an inclined surface gradually lowered toward the partition plate 22, the first sowing hole 35 is a capsule-shaped groove, and a plurality of first sowing holes 35 are evenly arranged on the wall surface of the fixed plate 33. The sowing structure also includes a discharge port 32, a chute 34, a control plate 37 and a second sowing hole 38. The discharge port 32 is opened through the top of the baffle 31, the chute 34 is opened through the side wall surface of the fixed plate 33, the control plate 37 is slidably connected in the chute 34, and the second sowing hole 38 is opened through the wall surface of the control plate 37. The chute 34 is a rectangular groove, the size of the control plate 37 is consistent with that of the chute 34, the upward wall of the control plate 37 is flush with the upward wall of the fixed plate 33, and each chute 34 is provided with a control plate 37. The second sowing hole 38 is also a capsule-shaped groove with the same size as the first sowing hole 35. The number of the second sowing holes 38 and the first sowing holes 35 is the same, and the position of the second sowing hole 38 is staggered from the first sowing hole 35 by half the size of the first sowing hole 35. The sowing structure also includes a limiting strip 36, a limiting block 39, and a pumping The plate 41 and the limiting groove 42, the limiting strip 36 is symmetrically fixedly connected to the upward inclined surface of the fixing plate 33, the limiting block 39 is also symmetrically fixedly connected to the upward inclined surface of the control plate 37, the draw plate 41 is fixedly connected to the mutually symmetrical side wall surfaces of the control plate 37 and the turntable 30, the width of the draw plate 41 is consistent with that of the control plate 37, the top of the draw plate 41 is also flush with the control plate 37, the limiting groove 42 is opened on the upward inclined surface of the draw plate 41, and the side wall surface of the limiting strip 36 and the side wall surface of the limiting block 39 facing the limiting strip 36 have a spacing;

[0028] In specific use, before use, it is necessary to manually pour the seeds to be sown into any space in the cavity of the loading box 20, and then pour the fertilizer into another space, and then push the device to the land where sowing is required and align the bottom of the loading box 20 with the sowing pit. At this time, the device is pushed along the sowing pit, and the power of the rotating motor 24 is turned on. When the device moves above each sowing pit, the rotating motor 24 will drive the turntable 30 to rotate 180 degrees, and the turntable 30 will drive the baffle 31, the fixing plate 33, the limiting strip 36, the control plate 37, the limiting block 39 and the pumping plate 41 to rotate at the same time. After completion, the symmetrical fixed plate 33 will face two separate spaces in the cavity of the loading box 20 in the symmetrical single-room bottom 23 spacing, and the seeds and fertilizers in the cavity of the loading box 20 will pass through the first sowing hole 35 and the second sowing hole 38 and enter the inner arc surface of the baffle 31, and then move together from the discharge port 32 to the sowing pit along the inner arc of the baffle 31, so as to complete the sowing of seeds and fertilizers. After each sowing is completed, the rotating motor 24 will drive the turntable 30 to rotate to its original state. When the turntable 30 rotates to its original state, the baffle 31 will block the symmetrical single-room bottom 23 spacing to prevent the fertilizer and seeds from flowing out;

[0029] In summary, by setting up a sowing structure, a higher sowing efficiency can be achieved, because the sowing structure drives the baffle 31, the fixed plate 33 and the control plate 37 to rotate simultaneously by rotating the turntable 30, and converts the state that originally blocked the seeds and fertilizers into an open state and mixes the two together when flowing out, thereby realizing the sowing of seeds. This process has only a short delay and a consistent speed, so compared with the prior art, the sowing efficiency of this solution is higher.

[0030] like Figure 1 and Figure 5 As shown, the sowing structure also includes a side plate 40, a groove 43, a base block 44 and a limit bolt 45. The side plate 40 is fixedly connected to the side wall surface of the baffle 31 which is symmetrical to the rotating disk 30. A circular groove adapted to the side plate 40 is opened at the position of the side plate 40 of the loading box 20. The side plate 40 can rotate in the circular groove. The side wall surface of the side plate 40 is flush with the wall surface of the corresponding side of the loading box 20. The groove 43 is symmetrically opened on the side wall surface of the side plate 40. The base block 44 is fixedly connected to the side wall surface of the side plate 40. The limit bolt 45 The limiting bolt 45 is threadedly connected to the wall of the base block 44. The drawout groove 43 can adapt to the sliding of the drawout plate 41. The drawout plate 41 can slide in the drawout groove 43. The symmetrical drawout grooves 43 are in an inverted eight-shaped shape. The bottom of the base block 44 and the upward inclined surface of the drawout plate 41 remain vertical. The wall of the base block 44 is penetrated with a thread groove adapted to the limiting bolt 45. The bottom of the limiting bolt 45 can pass through the thread groove of the wall of the base block 44 and enter the limiting groove 42. Each drawout groove 43 is provided with a base block 44 and a limiting bolt 45.

[0031] In specific use, when it is necessary to sow seeds of another different size, the bottom of the limit bolt 45 can be first screwed to a stop. Because the limit groove 42 fixes the position of the draw plate 41, the draw plate 41 can be slowly drawn toward the side plate 40. When the draw plate 41 is drawn, the control plate 37 is driven to move at the same time, and the control plate 37 drives the limit block 39 to move at the same time. When the wall surface of the limit block 39 contacts the wall surface of the limit strip 36, the control plate 37 and the draw plate 41 will move to the maximum limit. When the control plate 37 moves, the second sowing hole 38 and The staggered position of the first seeding hole 35 will change. The more the control plate 37 moves toward the side plate 40, the larger the size of the hole formed by the second seeding hole 38 and the first seeding hole 35. When the limiting bar 36 and the limiting block 39 are in contact, it means that the hole formed by the second seeding hole 38 and the first seeding hole 35 has reached the maximum value. After the adjustment of the draw plate 41 is completed, the limit bolt 45 is rotated back into the limit groove 42 and abutted against it to fix the position of the draw plate 41. When the draw plate 41 is fixed, the position of the control plate 37 is fixed.

[0032] In summary, by setting a control plate 37 that can be slidably adjusted, the hole size of the second sowing hole 38 and the first sowing hole 35 used for sowing seeds can be increased or decreased when sliding. The adjustable first sowing hole 35 and the second sowing hole 38 can increase the applicability of the device and can be used to sow seeds of different sizes.

[0033] Working principle: Before use, you need to manually pour the seeds to be sown into any space in the cavity of the loading box 20, and then pour the fertilizer into another space. Then push the device to the land where you want to sow and align the bottom of the loading box 20 with the sowing pit. At this time, push the device along the sowing pit and turn on the power of the rotating motor 24. When the device moves above each sowing pit, the rotating motor 24 will drive the turntable 30 to rotate 180 degrees. The turntable 30 will drive the baffle 31, the fixing plate 33, the limiting strip 36, the control plate 37, the limiting block 39 and the pumping plate 41 to rotate at the same time. When the turntable 30 rotates completely, After completion, the symmetrical fixed plates 33 will face the two separate spaces in the cavity of the loading box 20 in the symmetrical single-room bottom 23 spacing respectively. At this time, the seeds and fertilizers in the cavity of the loading box 20 will pass through the first sowing hole 35 and the second sowing hole 38 and enter the inner arc surface of the baffle 31, and then move together from the discharge port 32 to the sowing pit along the inner arc of the baffle 31, thereby completing the sowing of seeds and fertilizers. After each sowing is completed, the rotating motor 24 will drive the turntable 30 to its original state. When the turntable 30 rotates to its original state, the baffle 31 will block the symmetrical single-room bottom 23 spacing to prevent fertilizers and seeds from flowing out.
