Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Examples

Referring to fig. 1 and 2, the present invention provides a screw compressor 100, which includes a fixing bracket 10, a cylindrical housing 20, a screw propulsion mechanism 30 and a hydraulic knife 40; the casing sets up on fixed bolster 10, and feed inlet 201 has been seted up to casing one end, feed inlet 201 below, be located be provided with in the casing inner chamber spiral advancing mechanism 30 is equipped with discharge gate 202 at the casing other end, is equipped with hydraulic switch blade 40 in discharge gate 202 department, pressure sensor is installed to hydraulic switch blade 40 inside wall.

As shown in fig. 3, in order to achieve the stable fixing effect of the cylindrical shell 20, at least two sets of fixing plates 101 are mounted on the fixing bracket 10 along the extending direction of the cylinder, and each set of fixing plates 101 are respectively arranged at two sides of the cylindrical shell 20 and attached to the side wall of the cylindrical shell 20. The material loading mouth is located casing 20 up end, the material loading mouth is hopper-shaped structure, and its cross section includes rectangle or toper, and such design increase material loading mouth volume to the operator carries out the material loading operation.

The material is fed into the feeding port and then falls onto the screw propulsion mechanism 30 arranged below the feeding port, fig. 4 is a schematic structural diagram of the screw propulsion mechanism 30, the screw propulsion mechanism 30 includes a rotating main shaft 301 and a screw stop 304, and the screw stop 304 is formed on the rotating main shaft 301 and extends spirally along the axial direction of the rotating main shaft 301. As the spindle rotates, material is delivered to the discharge port 202 via rotation. In this embodiment, since the shaft diameter of the rotating main shaft 301 is smaller, a rotating cylinder 303 is further sleeved outside the rotating main shaft 301, the rotating cylinder 303 and the rotating main shaft 301 are connected and fixed through a plurality of connecting rods 302 and rotate along with the rotation of the rotating main shaft 301, two ends of the rotating cylinder 303 are closed, and a spiral baffle 304 is formed on the rotating cylinder 303.
