The invention discloses a dynamic filtering pressing dehydrator, comprising as least one filtering unit. Each filtering unit comprises two parallel filter plates; an elastic pressing frame consisting of an elastomer and a filtering frame is arranged between the two parallel filter plates at a position jointing the filter plate external edges; the filtering frame is arranged at an external side of the elastomer; the elastomer and the filter plates are fitted in seal; the elastic pressing frame and the two filter plates form a filter chamber; filter plate planes on two side of the filter chamber are pressing planes; a thickness of a filter plate at the filter plate plane is larger than a thickness at an elastomer bearing plane; and a thickness of the elastomer in an unpressed state is larger than a sum of an elastomer pre-pression amount and 3.3 times an elastomer compression amount. According to the invention, the thickness of the elastomer in the unpressed state is larger than the sum of the elastomer pre-pression amount and 3.3 times the elastomer compression amount, therefore the pressing planes restrict a pression rate of the elastomer; meanwhile the pre-pression on the elastomer before the pressing filtering prolongs a service life of the elastomer.

The invention discloses a self-adaption sand ground biomimetic mechanical foot, and belongs to a foot type robot mainly applied to walking on sand ground. The self-adaption sand ground biomimetic mechanical foot consists of a support frame, a linear motor, a connecting element, a first foot toe, a second foot toe, an elastic fabric, a buffer mechanism and the like, wherein the connecting element consists of a first connecting element, a second connecting element, a pin shaft and a screw stud; the buffer mechanism consists of a support frame, a foot sole, a spring and a connecting post, and is used for simulating an ostrich tarsometatarsus joint to achieve the buffer and shock absorption effects. The self-adaption sand ground biomimetic mechanical foot can achieve the beneficial effects that when the robot walks on the sand ground, the two toes are separated when the foot touches the ground; the elastic fabric spreads, so that the ground contact area is increased; the stability of the robot is improved; when the foot is lifted up, the two toes are closed and are overlapped for a certain area; the elastic fabric contracts; the stress area in the moving process is reduced. Meanwhile, the bottom of the first foot toe and the bottom of the second foot toe are provided with groove structures matched with the elastic fabric; the sand fixing and current limiting functions can be realized; the gait stability and the traction performance of the foot type robot can be improved.
