[0031] refer to Figure 5 to Figure 6 , Fig.14 , 15 , 16, side panels 270 are respectively provided on both sides of the right seed box 250 and the left seed box 260, and the side panel pin 271 at the lower part of each side panel 270 is slidably connected to the corresponding inclined groove 215, and the side panel guide rod 272 on the side of the side panel 270 is slidably connected to the corresponding left right-angle seat guide hole 264 or the right right-angle seat guide hole 254.

[0032] refer to Figure 5 to Figure 6 , Fig.14 , 1517, a connecting rod 280 is provided between the outer seat 210 and the right seed box 250 and the left seed box 260, a pin 218 is connected between the pin holes 217 corresponding to the two outer seats 210, the pin 218 is slidably connected to the connecting rod waist groove 281 between the connecting rods 280, and the connecting rod hole 282 on one side of the connecting rod 280 is hinged to the right seed box bearing seat 255 or the left seed box bearing seat 265, and the connecting rod 280 is a triangular structure. When adjusting the internal space of the right seed box 250, the left seed box 260, and the side plate 270, the connecting rod 280 blocks the space at the connection between the outer seat 210 and the right seed box 250 and the left seed box 260, and the triangular connecting rod 280 prevents the connecting rod 280 from protruding to the outside of the outer seat 210 and the right seed box 250 and the left seed box 260 when adjusting the weight and position, so as to prevent the tree seeds from leaking out or being scratched.

[0033] When the rack 240 moves toward the inside of the base 220, the two rack pins 242 of the rack 240 respectively drive the right seed box 250 and the left seed box 260 connected thereto to approach each other. When the right seed box 250 and the left seed box 260 approach each other, the side plates 270 on both sides of the right seed box 250 and the side plates 270 on both sides of the left seed box 260 are respectively driven by the inclined groove 215 to approach each other, and the internal space of the right seed box 250, the left seed box 260 and the side plates 270 becomes smaller. Anyway, when the rack 240 moves toward the outside of the base 220, the internal space of the right seed box 250, the left seed box 260 and the side plates 270 becomes larger, so that the device can adapt to the sowing of tree seeds of different sizes, and tree seeds of different sizes adapt to the internal space size of the right seed box 250, the left seed box 260 and the side plates 270, so that each right seed box 250, the left seed box 260 and the side plates 270 can obtain a tree seed each time without missing or re-seeding.

[0034] refer to Figures 1 to 4A seed box 111 is provided on the upper part of the machine body 110, and a group of bottom grooves 112 are evenly distributed on the bottom of the seed box 111. A seeding groove 113 is provided on the front side of the lower part of each bottom groove 112, and a plow 114 is provided at the lower part of each seeding groove 113. An axial hole 115 is provided on the side of the machine body 110, and a rotating connecting shaft 120 is arranged in the axial hole 115.

The shaft 120 is connected to the action device. When the shaft 120 rotates, it drives a group of seeding devices 200 to rotate. When the seeding devices 200 rotate, each group of right seed boxes 250, left seed boxes 260, and side plates 270 rotate in the seed box 111, and tree seeds fall into the internal space of the right seed box 250, left seed box 260, and side plates 270. When the tree seeds in the right seed box 250, left seed box 260, and side plates 270 rotate to the lower part with the seeding device 200, the tree seeds fall from the corresponding seeding grooves 113 into the furrows plowed by the plow 114. The tree seeds fall into the internal space of the right seed box 250, left seed box 260, and side plates 270 and are taken out with the rotation of the seeding device 200. The speed of sowing will not harm the tree seeds.

[0035] A method for using a tree planting and sowing device. When using the device, in the first step, the device is connected to a motor vehicle, tree seeds are placed in a seed box 111, and the shaft 120 is connected to power. In the second step, the motor vehicle pulls the device forward, and the plow 114 at the lower part of the body 110 plows a sowing groove. When the right seed box 250, the left seed box 260, and the side plate 270 of the seeding device 200 rotate into the seed box 111, the tree seeds fall into the internal space of the right seed box 250, the left seed box 260, and the side plate 270. When the tree seeds in the right seed box 250, the left seed box 260, and the side plate 270 rotate to the lower part with the seeding device 200, the tree seeds fall from the corresponding seeding groove 113 into the groove plowed by the plow 114. When the size of the tree seeds changes, the fixing bolt 310 is loosened, the gear ring 230 is rotated, and the gear ring 230 is rotated. The rotation drives a group of gears 290 to rotate, and the rotation of a group of gears 290 drives their respective racks 240 to move along the radial direction of the base 220. When the rack 240 moves toward the inside of the base 220, the two rack pins 242 of the rack 240 respectively drive the right seed box 250 and the left seed box 260 connected thereto to approach each other. When the right seed box 250 and the left seed box 260 approach each other, the side plates 270 on both sides of the right seed box 250 and the side plates 270 on both sides of the left seed box 260 are respectively driven by the inclined grooves 215 to approach each other, and the internal spaces of the right seed box 250, the left seed box 260 and the side plates 270 become smaller. Anyway, when the rack 240 moves toward the outside of the base 220, the internal spaces of the right seed box 250, the left seed box 260 and the side plates 270 become larger, so that the device can be adapted to the sowing of seeds of trees of different sizes.

[0036] When the size of the tree seeds changes, the fixing bolt 310 is loosened and the gear ring 230 is rotated. The gear ring 230 rotates to drive a group of gears 290 to rotate. The group of gears 290 rotates to drive their respective racks 240 to move along the radial direction of the base 220. When the rack 240 moves toward the inside of the base 220, the two rack pins 242 of the rack 240 respectively drive the right seed box 250 and the left seed box 260 connected thereto to approach each other. When the right seed box 250 and the left seed box 260 approach each other, the side plates 270 on both sides of the right seed box 250 and the side plates 270 on both sides of the left seed box 260 are respectively driven by the inclined grooves 215 to approach each other, and the internal space of the right seed box 250, the left seed box 260 and the side plates 270 becomes smaller. Anyway, when the rack 240 moves toward the outside of the base 220, the internal space of the right seed box 250, the left seed box 260 and the side plates 270 becomes smaller. The space becomes larger, so that the device can adapt to the sowing of tree seeds of different sizes. Tree seeds of different sizes adapt to the internal space size of the right seed box 250, the left seed box 260, and the side plate 270, so that each right seed box 250, the left seed box 260, and the side plate 270 can obtain a tree seed each time, and there will be no missed sowing or re-sowing. When the tree seeds in the right seed box 250, the left seed box 260, and the side plate 270 rotate to the lower part with the seeding device 200, the tree seeds fall from the corresponding seeding groove 113 into the furrow plowed by the plow 114, and the tree seeds fall into the internal space of the right seed box 250, the left seed box 260, and the side plate 270 and are taken out with the rotation of the seeding device 200. The speed of sowing will not harm the tree seeds, which is safer and can greatly improve the germination rate while improving the sowing speed.
