Claw type sand excavating part capable of preventing dust flying
The invention discloses a claw type sand excavating part capable of preventing dust flying. The claw type sand excavating part capable of preventing dust flying comprises a sand cylinder; a sand storage cavity with a downward opening is formed in the sand cylinder; a turnover device is arranged on the sand cylinder; the turnover device comprises six turnover grooves which are formed in the lower end of the circumferential end surface of the sand cylinder in the form of an annular array and have downward openings; connecting blocks with lower ends extending outside are arranged between the front and rear walls of the turnover grooves in a rotating manner; turnover claws are fixedly arranged at the lower ends of the connecting blocks; gas pumping devices are arranged in the wall of the sandstorage cavity; and a dust prevention device is arranged above the sand storage cavity. According to the claw type sand excavating part capable of preventing dust flying, more sands can be effectivelygrabbed, and moreover, the gas pumping devices suck sand between the turnover gaps in the sand excavating process to prevent larger fitting clearance caused by sand blockage so as to avoid sand leaking in the moving process; and as a communication opening of the dust prevention device is automatically opened or closed in the lowering and lifting process to effectively prevent dust flying in the sand moving process and improve the working environment.
本发明公开的一种防止沙尘飞扬的爪式挖沙部件，包括沙筒，所述沙筒上设有开口向下的存沙腔，所述沙筒上设有翻转装置，所述翻转装置包括环形阵列设于所述沙筒圆周端面下端且开口向下的六个翻转槽，所述翻转槽前后壁之间能转动的设有下端延伸至外的连接块，所述连接块下端固定设有翻转爪，所述存沙腔壁内设有抽气装置，所述存沙腔上方设有防尘装置，本发明可有效地抓起更多的沙子，并在挖沙的过程中抽气装置吸走翻转间隙之间的沙子，防止因沙子阻碍导致存在的较大配合间隙，进而避免移动的过程中沙子漏出，防尘装置在下降和上提的过程中自动开启或关闭连通口，有效防止移动沙子的过程中沙尘飞扬，改善工作环境。
