[0033] Embodiment 1

[0034] In order to solve the problem that the spacing adjustment operation of multiple sowing lines in the existing sand plant sowing device is relatively cumbersome, the following solution is disclosed, specifically as follows: Figure 1 , Figure 2 , Figure 3 As shown:

[0038] Embodiment 2

[0039] This embodiment is different from the first embodiment. Through the cooperation of the sowing mechanism 7 and the linkage assembly 6, the wide sowing of the sandy plant seeds is automatically realized during the forward movement of the driving vehicle, and the sowing width adjustment assembly 13 is used to adjust the sowing width. Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown:

[0041] The sowing mechanism 7 includes a material guide assembly 71 that passes through the bottom end of the seed box 8, and the bottom end of the material guide assembly 71 extends to the outside of the water tank 3, a plurality of material dividing baffles 72 are arranged at equal intervals on the inner side of the material guide assembly 71, and a diverter plate 75 is fixedly installed on the top end of the material guide assembly 71 above the material dividing baffles 72, a rotating cylinder 73 is movably connected to the inner side of the bottom end of the material guide assembly 71, and a plurality of groups of pushing blocks 74 are arranged at equal intervals on the outside of the rotating cylinder 73, and the outer ends of each group of pushing blocks 74 are correspondingly stuck in the gap channels between adjacent material dividing baffles 72;

[0042] The material guide assembly 71 includes a vertical guide tube 711 that passes through the bottom end of the seed box 8, and a chute plate 712 is fixedly connected to one side of the bottom end of the vertical guide tube 711, and a curved groove plate 713 is fixedly arranged at the bottom end of the chute plate 712. The diverter plate 75 is located at the side of the bottom end of the vertical guide tube 711 away from the chute plate 712, and the curvature of the curved groove plate 713 is adapted to the outer curvature of the rotating cylinder 73. The material dividing partition plate 72 is located on the chute plate 712 and the curved groove plate 713.

[0043] There are eight groups of pusher blocks 74, each group has eight pusher blocks, and each group of pusher blocks 74 is distributed in an annular pattern with equal spacing on the rotating cylinder 73. A special-shaped hole is provided through the axis of the rotating cylinder 73.

[0044] A plurality of spreading width adjustment components 13 are evenly arranged on the outside of the vertical guide tube 711, and the positions of the spreading width adjustment components 13 correspond to the gap channels between adjacent chute plates 712. The spreading width adjustment components 13 include a screw 131 rotatably connected to the outside of the vertical guide tube 711, and a threaded sleeve 132 is sleeved on the outside of the screw 131, and a baffle 133 is fixedly connected to one side of the threaded sleeve 132, and the bottom end of the baffle 133 is inserted into the gap between adjacent chute plates 712, and the baffle 133 is located below the pusher block 74;

[0045] The linkage assembly 6 includes two support seats 61 fixed on both sides of the roller frame 4, and a rotating shaft 62 is connected between the two support seats 61, and a plurality of fixing bars 63 are fixedly arranged outside the rotating shaft 62 located between the support seats 61, and the rotating shaft 62 and the fixing bars 63 are all passed through the special-shaped holes on the rotating cylinder 73, and gears 64 are arranged at both ends of the rotating shaft 62, and the gears 64 and the power shaft of the rear driving vehicle are connected by a tooth chain, so that the driving vehicle drives the rotating shaft 62 to rotate during the forward movement, and then the rotating cylinder 73 is rotated;

[0047] In this embodiment, when in use, water is filled inside the water tank 3, and seeds are filled into the seed box 8. Under the action of gravity, the seeds automatically move downward along the material guide component 71, and are diverted by the diverter plate 75, so that the seeds roll along the inclined slot plate 712 and the curved slot plate 713, and the dividing effect of the material dividing partition 72 is utilized to make the seeds uniformly distributed laterally. Since the driving shaft of the driving vehicle drives the toothed chain to move, the gear 64 rotates, and then the rotating shaft 62 rotates, the rotating cylinder 73 rotates, and the pushing block 74 rotates to the seed channel between the material dividing partitions 72, so that the pushing block 74 drives the seeds to move along the direction of the curved slot plate 713 during the rotation process, and the driving force of the rotation is utilized to make the seeds finally distributed in a wide range and sprinkled forward, and during the sowing process, the seeds are dispersed in the air, so that the seeds are evenly distributed in a wide range and fall into the sowing furrow, and the seeds are piled up;

[0048] At the same time, during the sowing process, the control valve 123 is first adjusted to control the amount of water passing through the U-shaped water pipe 121 to the water tank 3, so that the water flows downward along the nozzle 122 during the sowing process. As the seeds are sown forward, the water flows downward, and then after the seeds are sown, the seeds are automatically irrigated to improve the survival rate of the seeds;

[0049] According to the sowing requirements, the screw 131 can be screwed to make the threaded sleeve 132 move upward or downward along the screw 131, so that the baffle 133 is inserted into the gap between adjacent material dividing partitions 72 or pulled out, and then the channel is blocked and adjusted to adjust the distribution width of the entire seed, thereby achieving adaptive adjustment of the distribution width of seeds in different sandy soils.

[0050] Embodiment 3

[0051] This embodiment is different from the first and second embodiments. The depth of the bottom end of the bulldozer 551 inserted into the soil is adjusted through the depth adjustment mechanism 5 to meet the requirements of different planting depths of sandy plant seeds. Figure 1 and Figure 7 As shown:

[0052] A depth adjustment mechanism 5 is provided on the front side of the multiple water tanks 3, and both ends of the depth adjustment mechanism 5 are connected to one side of the connecting frame 1. The depth adjustment mechanism 5 includes a support sleeve 51 installed on both sides of the connecting frame 1, and the interior of the support sleeve 51 is slidably connected with an arc guide plate 52, and the sliding track of the arc guide plate 52 is in an arc shape, and one end of the two arc guide plates 52 is commonly connected to a connecting rod 54, and the arc guide plate 52 is hinged on one side of the roller frame 4. The electric telescopic rod 53 is hinged at one end of the electric telescopic rod 53 and one end of the electric telescopic rod 53 is hinged to one side of the roller frame 4, and the initial state of the electric telescopic rod 53 is inclined, and the outer sleeve of the connecting rod 54 is provided with a plurality of ditching components 55, and one side of the ditching components 55 is hinged to the outer side of the corresponding water tank 3;

[0053] The trenching assembly 55 includes a bulldozer plate 551 hinged on the outside of the water tank 3, and an arc-shaped seed retaining plate 552 is installed on the top of the bulldozer plate 551 close to the water tank 3. A fixed sleeve 553 is fixedly connected to the outside of the bulldozer plate 551, and a connecting rod 54 passes through the inside of the fixed sleeve 553. The cross-section of the arc-shaped guide plate 52 is a quarter-circular arc, and the center of the arc-shaped guide plate 52 and the axis of the bulldozer plate 551 are colinearly distributed.

[0054] In this embodiment, when in use, the electric telescopic rod 53 is started to shorten, so that the relative distance between the electric telescopic rod 53 and the arc guide plate 52 is shortened. Since the arc guide plate 52 and the support sleeve 51 are slidably connected, the electric telescopic rod 53 pulls the arc guide plate 52 to slide upward inside the support sleeve 51. Due to the movement of the arc guide plate 52, one end of the arc guide plate 52 pulls the connecting rod 54 to move, so that the bulldozer 551 rotates at the hinge point. Since the bulldozer 551 is initially inclined outward, the bulldozer 551 rotates inward at this time, and then the relative distance between the bottom end of the bulldozer 551 and the sandy soil is adjusted, so that the bottom end of the bulldozer 551 penetrates deeper into the sandy soil. Then, under the movement of the driving vehicle, the bulldozer 551 forms an adjustment effect on the trenching depth during the forward movement to meet the device requirements of different sandy plants.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
