Garbage compression dehydrator

The invention discloses a garbage compression dehydrator. The garbage compression dehydrator comprises a box body, wherein sliding devices are slidably arranged on the left side and the right side inside the box body; the left end of the left sliding device is connected with an oil cylinder I, the right end of the left sliding device is provided with an ejecting head I, and the oil cylinder I penetrates out of the left side wall of the box body to be electrically connected with a control device; an ejecting head II is arranged at the left end of the right sliding device, an oil cylinder III isconnected to the right end of the right sliding device, and the oil cylinder III penetrates out of the right side wall of the box body to be electrically connected with a control device; a slag discharging port, a water outlet hole and a discharging port are sequentially formed in the bottom end of the box body from left to right, a feeding port is formed in the upper end of the box body, and a hopper is arranged on the feeding port; and a hopper inserting plate is connected to the lower end of the hopper in an inserted mode, and the other end of the hopper inserting plate is connected with an oil cylinder II. According to the garbage compression dehydrator, a relay is adopted to control a circuit and control the oil cylinders to work, so that the automatic circulation process is realized, the structure is simple, the operation and maintenance are convenient, and the safety is high; the oil cylinders are adopted to provide squeezing force, the power is large, no conveying moving gap is achieved, the stability is good, and garbage is squeezed and dehydrated more fully and thoroughly.
