A protecting shell 16 is arranged between the grass poking wheel 21 and the grass pressing wheel 42, and the protecting shell 16 is detachably connected with the frame 1. The provision of the protective casing 16 not only further enables the sand barrier paving machine to carry more sand barrier material for subsequent use in paving sand barriers, but also prevents the effects of wind on the sand barrier material paving. A hanging ear (not shown in the figure) is arranged above the protective shell 16, and the bottom of the hanging ear is fixedly connected with the protective shell 16. In an alternative embodiment, the number of the lugs is two, and the lugs are respectively positioned at the left end and the right end of the protecting shell 16, so as to facilitate the dismounting of the protecting shell 16 from the frame 1.
Wind shielding cloth (not shown) is optionally hung on the front end and the left and right sides of the frame 1, so as to prevent wind from blowing off uncompacted sand barrier materials combed on the ground from the front end and the left and right sides of the sand barrier paving machine, thereby being unfavorable for paving the sand barrier materials.
The sand barrier paving machine has small size and weight and 3 meters of front-back length under the condition of comprising three stations; the left and right width is 2.7 meters; the height of the upper part and the lower part is 1 meter; the weight is 1.6 tons, and the device is suitable for hillside low land and windward slopes of deserts or sandlands, and can be used for paving sand barrier materials on the slopes of deserts or sandlands of 15-20 degrees.
The working process comprises the following steps:
step 1: placing sand-protecting material at the front end of the conveyor belt 31, wherein the sand-protecting material moves towards the grass poking wheel 21 under the drive of the conveyor belt 31;
step 2: the grass pulling wheel 21 utilizes the teeth 211 to comb the sand barrier material on the conveyor belt 31 to the ground;
step 3: the grass pressing roller 41 compacts the sand barrier material combed on the ground under the traction of the frame 1;
step 4: the grass-pressing wheel 42 presses the portion of the compacted sand-protecting material that is in contact with the grass-pressing wheel 42 into the ground under the traction of the frame 1.
