(6) in the advancing process of the grass square, the soil compacting wheel is just positioned in the groove to compact the sandy soil on the straws in the groove, so that the laying work of the grass square is completed.

Therefore, the automatic grass square grid laying equipment 10 can ensure the stability of the laid grass square grids by digging sand and ditching, transversely laying straws, pressing a rod to enter a groove, filling sand and compacting sandy soil. Further, the spreading assembly 320 can extrude the straws at the discharge port 312, and the flattened straws are easier to bend and less prone to rebound, the probability that the straws are broken by pressing can be reduced, and the stability of the paved grass square is further improved.

Moreover, the sand feeding and filling assembly 510 can continuously convey the sand and soil scooped up by the ditching wheel 210 to the straws in the grooves, so that a sand and soil tank structure carrying the sand and soil is omitted, and the volume of the automatic grass square grid laying equipment 10 is reduced. Further, the vehicle body 100 has a driving function, and a traction mechanism is not required to be additionally provided, so that the volume of the automatic grass grid laying apparatus 10 is further reduced, and the automatic grass grid laying apparatus 10 can be applied to complex terrains such as sand dunes and ravines. Therefore, the automatic grass grid laying device 10 has high applicability and convenience in use.

In some embodiments, the trenching wheel 210 comprises a shaft sleeve 212 rotatably mounted to the support structure and a plurality of sanding teeth 213 disposed on the shaft sleeve 212 at spaced intervals circumferentially of the shaft sleeve 212. The side of each sanding tooth 213 is formed with a sand trap cavity 211. The opening direction of the sand trap chamber 211 coincides with the rotation direction of the shaft sleeve 212. The excavating drive member is used to provide a driving force to rotate the shaft sleeve 212 to rotate each excavating tooth 213, so as to scoop up and collect the sand on the ground in the sand collecting cavity 211.

In the process that the sand digging driving piece drives the rotating shaft sleeve 212 to drive the sand digging teeth 213 to rotate, the sand digging teeth 213 rotating around the central axis of the rotating shaft sleeve 212 can shovel sand on the ground to form a groove on the ground, and meanwhile, the shoveled sand can directly enter the sand collecting cavity 211 while the sand digging teeth 213 rotate, so that the sand is collected.

Further, in some embodiments, the sanding tooth 213 includes a bottom plate 2131, two side plates 2132, and an end plate 2133. One end of the bottom plate 2131 and one end of the side plate 2132 are fixedly arranged on the rotating shaft sleeve 212; the two side plates 2132 are provided on the bottom plate 2131 at intervals in the axial direction of the shaft sleeve 212. The end plate 2133 is fixedly arranged at one end of the bottom plate 2131 deviating from the rotating shaft sleeve 212 and at one end of the side plate 2132 deviating from the rotating shaft sleeve 212. The sand trap 211 is formed by surrounding the surfaces of the bottom plate 2131, the two side plates 2132, the end plate 2133 and the shaft sleeve 212.

The crank-slider mechanism 411 is arranged to enable the pressing rod body 420 to vertically ascend and descend, so as to ensure the pressing rod effect.

In some embodiments, the strut body 420 is a rectangular frustum structure with a cross-sectional area that gradually decreases in a vertically downward direction. The pressure lever body 420 is arranged to be of a quadrangular frustum pyramid structure, so that the probability that the pressure lever body 420 brings out sandy soil in the groove when resetting after pressing down the straw is reduced, and the interference in the subsequent process of sandy soil ditch filling is avoided.

Referring to fig. 1, 5 and 6, in some embodiments, the sand feeding assembly 510 includes a conveyor 511, a conveyor pipe 512 and a material homogenizing rotating shaft 513.

Specifically, in the present embodiment, the plurality of material homogenizing rotating shafts 513 are arranged in parallel and at intervals.

In the actual use process, in the rotation process of the ditching wheel 210, the ditching wheel 210 shovels and collects sandy soil on the ground into the sand collecting cavity 211, the sandy soil in the sand collecting cavity 211 is conveyed to the lower end of the conveyor belt mechanism 511 along with the rotation of the ditching wheel 210, and then the conveyor belt mechanism 511 is used for conveying the sandy soil obliquely upwards to the upper end of the conveyor belt mechanism 511 and dropping into the material conveying pipe 512 in the operation process of the conveyor belt mechanism 511; the sandy soil in the material conveying pipe 512 moves to the opening provided with the material homogenizing rotating shaft 513 under the action of the gravity of the sandy soil, and the material homogenizing rotating shaft 513 rotates under the action of the impact force of the sandy soil, so that the sandy soil is uniformly paved on the straws in the grooves, and the stability of the paved grass square is further improved.

Further, in some embodiments, sand feeding and filling component 510 also includes a sand storage bin 514. The top end and the lower end of the sand storage box 514 are respectively provided with a sand inlet (shown by the figure) and a sand outlet (not shown by the figure).
