The double-screw extruder comprises an extruder body, the input end of the extruder body is communicated with a conveying pipe used for conveying raw materials for producing the grass-proof cloth, the top of the conveying pipe is communicated with a feeding hopper, and the top of one side of the feeding hopper is fixedly connected with a semicircular disc. A cleaning assembly used for cleaning the inner wall of the feeding hopper is arranged at the top of the semicircular disc, and a sealing assembly used for sealing the opening of the feeding hopper is arranged on one side of the semicircular disc. Through the arrangement of the cleaning assembly, the scraping plate can continuously scrape the inner wall of the feeding hopper, attached raw materials are removed in time, raw material accumulation is avoided, and the service life of the feeding hopper is prolonged. Meanwhile, through the cooperation of the spring, the sliding disc and the push rod, the position of the scraper blade can be adjusted in a self-adaptive mode according to the actual situation of the inner wall of the feeding hopper, the scraper blade is always in close contact with the inner wall, cleaning can be effectively conducted, and the stripping effect on raw materials attached to the inner wall of the feeding hopper is guaranteed.

The utility model belongs to the field of road sign spraying, and particularly relates to a ground road sign spraying device which comprises a cart. A spraying box is fixedly connected to the top of the cart, a spraying head is arranged at the bottom of the spraying box, a protective frame is fixedly connected to the side face of the cart, an electric push rod is fixedly connected to the top of the protective frame, and the output end of the electric push rod penetrates through the protective frame and is fixedly connected with a moving plate. A motor is fixedly connected to the top of the movable plate, a fixed plate is fixedly connected to the side face of the movable plate, and a cleaning rod is rotationally connected to the inner side of the fixed plate; the cleaning rod is continuously driven by the motor to rotate, the ground to be sprayed by the spraying head can be cleaned, the cleaning rod can be driven by the electric push rod to move up and down, the cleanable height of the cleaning rod is adjusted, the cleaning rod is made to adapt to the ground of different heights, the contact strength of the surface of the cleaning rod and the ground is increased, and the ground cleaning efficiency is improved.

The utility model discloses an electric heater temperature control device which comprises a temperature controller, one side of the temperature controller is in threaded connection with a screw rod, the outer side of one end of the screw rod is fixedly connected with a pressing ring, and the pressing ring is matched with a U-shaped limiting hole to enable a lifting frame to descend to the height where a protection frame and an inner plate shade the key position of the temperature controller. The screw is rotated clockwise to drive the pressing ring to extrude the gasket, the contact strength of the gasket and one side of the lifting frame is improved, and therefore the position of the lifting frame is fixed, and when temperature adjustment is needed, the screw is rotated anticlockwise and loosened, the strength of the gasket on one side of the pressing ring to extrude the lifting frame is reduced, and therefore the lifting frame is loosened. The lifting frame and the inner plate on one side of the lifting frame are lifted to the required height by matching with the U-shaped limiting hole, the key on one side of the temperature controller is exposed in the environment and finally adjusted, and the situation that the set temperature fluctuates due to mistaken touch of personnel can be effectively reduced through shielding the key position of the temperature controller by the protection frame and the inner plate.

The utility model discloses a rail type lifting system, which belongs to the field of lifting systems, solves the problems that the power supply mode of the existing lifting mechanism can influence the use of the lifting mechanism and has potential safety hazards, and adopts the technical scheme that the rail type lifting system mainly comprises a power supply rail, a pulley and a lifting mechanism, the tackle is connected to the track in a sliding mode and can slide in the direction limited by the track, the lifting mechanism is hung on the tackle through a detachable mechanical coupling device, the tackle is provided with an electricity taking device, the electricity taking device comprises an electricity taking end and a female end electric coupler, the electricity taking end is in electrical contact with the conductive element when the tackle slides, and the female end electric coupler is in electrical contact with the conductive element when the tackle slides. The lifting mechanism is provided with a male end electric coupler, the female end electric coupler and the male end electric coupler form a detachable electric coupling device, and the female end electric coupler and the male end electric coupler are configured to be synchronously aligned to form electric connection when the detachable mechanical coupling device is connected. The charging device is mainly used for charging the lifting mechanism at any position of the whole track.

The application provides an environment-friendly building outer decoration construction equipment and method, which comprises a transverse moving part, a rotating part, an extension assembly, a painting assembly and a feeding assembly. The elevator drives the hanging basket to move along the outer wall, connects the hose with the extension pipe, and makes the primer in the storage tank enter the hollow shaft through the hose and the extension pipe by the suction pump, enters the rotating roller through the hole, and enters the brush body layer from the leakage hole. The transverse movement of the transverse moving part makes the rotating roller rotate along the outer wall, and the brush body layer paints the outer wall. The extension assembly makes the brush body layer have a greater contact force with the outer wall, so that the primer can better penetrate into the wall. When painting the window, the rotating part drives the painting assembly to rotate to the horizontal or vertical state, and then the extension assembly drives the painting assembly to move forward and backward. The transverse moving part moves transversely or the hanging basket moves up and down to cooperate with the painting assembly, so that the horizontal and vertical direction painting of the window is completed. The painting of the outer wall and the window can be automatically completed, and the painting effect is better.
