[0017] 1. The present invention is provided with a covering component to turn over the surface of the sand dune and to transmit the soil to cover the surface layer of the sand where the grass and shrub seeds and the sand-fixing agent are sprayed. When the mobile frame moves on the sand, the main turning wheel and the auxiliary turning wheel turn over the sand on the surface layer of the sand. The auxiliary turning wheel turns over and loosens the sand within the spraying range of the spraying tube, so that the sprayed grass and shrub seeds and the sand-fixing agent can enter the sand. The feeding shovel on the main turning wheel transfers part of the turned and loosened sand to the sand transmission box during the circular rotation.

[0018] 2. The present invention is provided with a pushing assembly and a vibrating assembly to accelerate the discharge of sand in the sand transmission box. When the auxiliary flipping wheel rotates to push the sand, it drives the driving bevel gear to rotate through the secondary pulley transmission assembly. Under the action of the gear transmission structure, the turntable is controlled to rotate. The turntable pushes the sliding rod to engage and slide in the slideway. Under the action of the sliding structure, the pushing plate is controlled to reciprocate in the sand transmission box, pushing the sand in the sand transmission box to quickly enter the covering soil guide channels on both sides, and assisting the discharge of sand outwards. The driving bevel gear drives the cam to rotate synchronously when rotating, and the rotating rod connected between the cam and the vibration seat rotates accordingly. The rotating rotating rod controls the vibration seat to reciprocate above the vibration plate accordingly. The vibration force of the vibration seat is transmitted to the covering soil guide channel, further accelerating the discharge of sand outwards, and avoiding the accumulation of some sand with high water content in the sand transmission box and the covering soil guide channel.

[0019] 3. The present invention is provided with a quantitative sowing component to adjust the density of the sprayed shrub and grass seeds according to the current vegetation growth conditions of the sand dunes. The electric telescopic rod is operated to push the positioning block to move, and the storage channel is pushed to move in a directional manner in the material trough under the transmission action of the support rod. The position of the storage channel in the material trough is adjusted to correspond to the position of the storage channel in the material trough, thereby regulating the number of shrub and grass seeds transmitted in the combined space of the storage channel and the material trough, thereby realizing the adjustment of the spraying density of the shrub and grass seeds.

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] See also Figure 1-Figure 5 , Figure 9-Figure 14 As shown, a sand dune control device for spraying sand fixation agent and grass seeds in an integrated manner comprises a mobile frame 1 rolling on the sand, the sand dune control device also comprises a support frame 11 fixed on the mobile frame 1, a primary storage box 12 for holding grass seeds is fixedly installed on the support frame 11, a secondary storage box 13 for holding sand fixation agent is fixedly installed on the support frame 11, a transmission pipe 14 is connected through the discharge ports below the primary storage box 12 and the secondary storage box 13, and a spray port for spraying grass seeds and sand fixation agent under pressure is installed at the port of the transmission pipe 14 Tube 15; a covering component 2 is provided on the mobile frame 1 for pushing and collecting sand and transmitting the sand to cover the surface of the dune after spraying shrub seeds and sand fixation agents; a quantitative sowing component 5 is provided at the lower port of the first-level storage box 12 for controlling the density of the sprayed shrub seeds; the mobile frame 1 is connected to a vehicle that can be driven on the ground of the dunes, and a plurality of groups of first-level storage boxes 12 and second-level storage boxes 13 are installed on the mobile frame 1 to expand the range of spraying shrub seeds and sand fixation agents, and a group of covering components 2 is arranged between two adjacent first-level storage boxes 12.

[0041] The device is controlled to move on the sand by the mobile frame 1, and the grass seeds in the primary storage box 12 are adjusted by the spraying density of the quantitative sowing component 5 and enter the transmission pipe 14. The sand-fixing agent in the secondary storage box 13 enters the transmission pipe 14 through the control of the pipeline valve. A spraying pipe 15 is installed at the front end of the transmission pipe 14. The sand-fixing agent and grass seeds in the transmission pipe 14 are mixed and sprayed on the sand through the spraying pipe 15. After growing on the sand, the grass seeds can fix the sand source and improve the environment of the sand dunes.

[0042] When the mobile frame 1 is moving, the soil covering component 2 pushes and loosens the sand on the surface of the sand so that the grass seeds to be sprayed can enter the sand. The soil covering component 2 can collect and transmit the overturned sand, and after transmission, the collected sand is covered on the surface of the sand where the grass seeds and sand fixation agent are sprayed, so as to avoid the grass seeds being directly sprayed on the sand surface, improve the wind resistance of the grass seeds after spraying, and thus improve the germination rate of the grass seeds sprayed.

[0043] See also Figure 1-Figure 3 , Figure 9-Figure 14 As shown, the soil covering component 2 includes a sand and soil transmission box 21 fixed on the mobile frame 1, a main tipping wheel 22 is rotatably installed in the sand and soil transmission box 21, two auxiliary tipping wheels 23 are symmetrically installed on the sand and soil transmission box 21 about the main tipping wheel 22, and soil covering material guide channels 24 corresponding to the position of the spraying tube 15 are connected on both sides of the sand and soil transmission box 21; a feeding shovel 221 is fixed at an equal angle on the main tipping wheel 22; a motor 231 is fixedly installed on the mobile frame 1, a primary pulley transmission assembly 232 is connected between the output end of the motor 231 and the shaft of the auxiliary tipping wheel 23, a driving gear 233 is fixed on the shaft of the auxiliary tipping wheel 23, a transmission gear 234 is rotatably installed on the sand and soil transmission box 21, a driven gear 235 is fixed on the shaft of the main tipping wheel 22, and the driving gear 233, the transmission gear 234 and the driven gear 235 are meshed and assembled in sequence; a plurality of strip rods 241 are fixed at equal intervals at the lower end of the soil covering material guide channel 24.

[0044] The running motor 231 drives the auxiliary tipping wheel 23 to rotate through the primary pulley transmission assembly 232. The auxiliary tipping wheel 23 corresponds to the side and lower position of the spraying tube 15. The auxiliary tipping wheel 23 pushes and loosens the sand within the spraying range of the spraying tube 15 so that the grass seeds and sand fixation agents sprayed by the spraying tube 15 can enter the sand.

[0045] When the auxiliary tipping wheel 23 rotates, it drives the driving gear 233 to rotate synchronously. The driving gear 233, the transmission gear 234 and the driven gear 235 are meshed and assembled in sequence. Under the gear meshing transmission action, the driven gear 235 and the main tipping wheel 22 are driven to rotate. When the main tipping wheel 22 rotates, the surface layer of sand is pushed and loosened, and the feeding shovel 221 circumferentially distributed on the main tipping wheel 22 transmits part of the loosened sand to the sand transmission box 21 during the circumferential rotation. The sand slides downward on the inclined surface in the sand transmission box 21 and enters the soil covering and guiding channels 24 on both sides. The sand is discharged to the outside of the equipment through the strip rods 241 under the soil covering and guiding channels 24. The soil covering and guiding channels 24 correspond to the front of the spraying pipe 15, and the sand is re-covered on the sand surface where the spraying pipe 15 sprays the shrub seeds and sand fixation agent, thereby improving the protection of the sprayed shrub seeds.

[0046] See also Figure 9-Figure 17 As shown, a pushing assembly 3 is provided in the sand transmission box 21 for pushing the sand to quickly enter the soil covering material guiding channel 24 .

[0047] The sand in the sand transmission box 21 is pushed by the pushing assembly 3 so that the sand quickly enters the soil covering material guiding channel 24 , thereby preventing the sand from accumulating and clogging in the sand transmission box 21 .

[0048] See also Figure 9-Figure 17 As shown, the pushing assembly 3 includes a guide rod 31 fixed in the sand transmission box 21, a pushing plate 32 is slidably installed on the guide rod 31, a slideway 33 is fixedly installed on the pushing plate 32, a turntable 34 is rotatably installed in the sand transmission box 21, a slide bar 35 is eccentrically fixed on the turntable 34, and the slide bar 35 is slidably assembled with the slideway 33; a driven bevel gear 36 is coaxially fixedly connected to the turntable 34, a driving bevel gear 37 meshing with the driven bevel gear 36 is rotatably installed in the sand transmission box 21, and a secondary pulley transmission assembly 38 is connected between the driving bevel gear 37 and the transmission gear 234.

[0049] When the auxiliary tipping wheel 23 rotates, it drives the driving bevel gear 37 to rotate through the secondary pulley transmission assembly 38. The driving bevel gear 37 controls the rotation of the driven bevel gear 36 through meshing transmission. The driven bevel gear 36 drives the turntable 34 to rotate synchronously. The sliding rod 35 fixed under the turntable 34 rotates in a circle. The sliding rod 35 is engaged in the slideway 33 and slides. Under the driving action of the sliding structure, the pushing plate 32 moves back and forth along the direction of the guide rod 31. The pushing plate 32 pushes the sand in the sand transmission box 21 back and forth into the soil covering material guide channel 24 on the left and right sides to maintain the smoothness of the sand transmission.

[0050] See also Figure 9-11 and Fig.15 As shown, the sand transmission box 21 is provided with a vibrating material assembly 4 for vibrating and discharging the sand in the covering soil guiding channel 24.

[0051] When the pushing component 3 pushes the sand, it provides power for the vibrating component 4 , and the vibrating component 4 acts on the surface of the soil covering material guiding channel 24 to further accelerate the discharge of sand in the soil covering material guiding channel 24 .

[0052] See also Figure 9-11 and Fig.15 As shown, the vibrating material assembly 4 includes a vibrating seat 41 which is vertically corresponding to the soil covering material guiding channel 24 and is slidably mounted on the sand transmission box 21, a vibrating plate 42 is fixed on the soil covering material guiding channel 24, a cam 43 which is coaxially fixedly connected to the driving bevel gear 37 is rotatably mounted on the sand transmission box 21, a rotating rod 44 is rotatably connected to the cam 43, and the rotating rod 44 is rotatably assembled with the vibrating seat 41.

[0053] The rotation of the driven bevel gear 36 drives the cam 43 to rotate synchronously, and the rotating rod 44 connected between the cam 43 and the vibration seat 41 rotates accordingly. The rotating rotating rod 44 pushes the vibration seat 41 connected to the outside of the sand transmission box 21 to reciprocate up and down. The reciprocating vibration seat 41 acts on the surface of the vibration plate 42. The vibration force of the reciprocating movement of the vibration seat 41 is transmitted to the soil covering material guiding channel 24, and the sand in the soil covering material guiding channel 24 is accelerated to be discharged outward by the vibration.

[0055] The discharging roller 52 is controlled to rotate by a driver, and the material trough 53 opened on the outside of the discharging roller 52 rotates in a circle. The material troughs 53 at different positions rotate in turn to correspond to the lower position of the primary storage box 12, and the shrub and grass seeds in the primary storage box 12 enter the material trough 53 below. When the material trough 53 rotates with the opening facing downward, the shrub and grass seeds in the material trough 53 enter the transmission pipe 14 below. The shrub and grass seeds and the sand-fixing agent in the transmission pipe 14 are mixed with each other and sprayed out through the spraying pipe 15. The density of the sprayed shrub and grass seeds can be adjusted according to the current vegetation growth of the sand dunes. The position of the storage channel 54 corresponding to the material trough 53 can be adjusted by the power component 55, and the storage space of the combination of the storage channel 54 and the material trough 53 can be adjusted, so as to control the amount of shrub and grass seeds transmitted to the transmission pipe 14.

[0056] See also Figure 1-Figure 8As shown, the power assembly 55 includes a positioning column 551 slidably installed in the discharge roller 52 and fixedly assembled with the storage channel 54, an electric telescopic rod 552 is fixed in the discharge roller 52, a positioning block 553 is fixed to the telescopic end of the electric telescopic rod 552, a support rod 554 is rotatably connected to the positioning block 553, and the support rod 554 is rotatably connected to the positioning column 551.

[0057] The electric telescopic rod 552 is operated to push the positioning block 553 to move horizontally, and the support rod 554 connected between the positioning block 553 and the positioning column 551 rotates accordingly. The rotating support rod 554 pushes the positioning column 551 connected to the discharge roller 52 to slide and move. The positioning column 551 drives the storage channel 54 to move synchronously, and adjusts the position of the storage channel 54 corresponding to the discharge roller 52.

[0058] See also Figure 3-Figure 6 As shown, the primary storage box 12 is provided with a dredging component 56 for dredging the grass seeds to evenly enter the discharge pipe 51.

[0059] When the discharging roller 52 rotates to transmit the grass seeds, it drives the dredging component 56 to move, dredges the grass seeds in the primary storage box 12, and maintains smooth transmission of the grass seeds.

[0060] See also Figure 3-Figure 6 As shown, the dredging assembly 56 includes a lifting rod 561 slidably installed in the primary storage box 12, a dredging rod 562 is fixedly installed on the lifting rod 561, a driving wheel 563 coaxially connected to the discharging roller 52 is rotatably installed on the discharge pipe 51, a transmission rod 564 is rotatably connected to the driving wheel 563, and the transmission rod 564 and the lifting rod 561 are rotatably assembled.

[0061] When the discharging roller 52 rotates, it drives the driving wheel 563 to rotate synchronously, and the transmission rod 564 connected between the driving wheel 563 and the lifting rod 561 rotates accordingly.
