Sand ball negative pressure suck-back sand filling device

Abstract

The invention discloses a sand ball negative pressure suck-back sand filling device and relates to the technical field of sand filling devices. The sand ball negative pressure suck-back sand filling device aims to solve the problems that sand flows down from a sand filling pipe to generate a large amount of dust and potential safety hazards are large and specifically comprises a machine body, a partition plate is arranged on the inner wall of one side of the machine body, a thick barrier is arranged on the outer wall of one side of the partition plate and is inclined, a material discharging plate is arranged on the outer wall of one side of the machine body, a supporting seat is arranged on the inner wall of the side, away from the partition plate, of the machine body, a support seat is arranged on the inner wall of one side of the machine body, the same second filter plate is arranged on the outer wall of one side of the support seat and the outer wall of one side of the supporting seat, and the same first filter plate is arranged on the outer wall of one side of the support seat and the outer wall of the top of the supporting seat. By means of the sand ball negative pressure suck-back sand filling device, large impurities and the dust in the sand are effectively removed, the density of the sand in the later sand filling operation is ensured, the sand filling quality is improved, the dust is prevented from appearing in sand filling, and atmospheric pollution and human body inhalation caused by all-around ejection of the dust in the sand are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of sand filling devices, in particular to a sand ball negative pressure back suction sand filling device. Background technique [0002] With the gradual improvement of people's living standards and the acceleration of the pace of life, people attach great importance to physical exercise and fitness; when exercising and fitness, some people use soft dumbbells for walking, running, aerobics, arm exercises, etc., and use soft dumbbells to exercise The advantages are: the soft dumbbell is small and flexible, not easy to hurt the feet and the floor, and is a safe and practical physical exercise product. However, soft dumbbells also have their disadvantages: in running and walking, which take a little longer, holding a single pair of dumbbells can easily cause hand fatigue and stiffness, and sand balls play a certain role. The existing sand balls need to be manually operated during the sand filling process, and t...
