Embodiment Construction

[0022] The invention will be further described below in conjunction with the accompanying drawings: as shown in the figure, the shotcrete machine includes a frame 1, and the frame is provided with a hopper 2 and a discharge device, and the hopper is made of a feeding material made of a soft material. The pipe 4 communicates with the discharge device, and at least one cutting device 5 is provided on the frame, and the cutting device includes at least two clamping parts 6 with adjustable spacing, and the two clamping parts are correspondingly arranged on the On both sides of the feeding pipe, two clamping parts are used to make the inner walls on both sides of the feeding pipe contact and seal when clamping. The clamping parts can be moved by linear motors, cylinders or other power sources. When the two clamping parts clamp the outer wall of the feeding pipe, the inner wall of the feeding pipe shrinks. When the two sides of the inner wall of the feeding pipe touch, the feeding T...

Abstract

The invention discloses a shotcreting machine, mainly aiming to solve the problems of proneness to wear and short service life when wedge discs of existing shotcreting machines are arranged in delivery pipes. The shotcreting machine is characterized in that a hopper is communicated with a discharging device through a delivery pipe (4) made of a soft material, and at least one cut-off device (5) isarranged on a frame and comprises at least two distance adjustable clamping elements (6) which are arranged on two sides of the delivery pipe correspondingly and used for contact sealing of the two inner walls of the delivery pipe during clamping. The shotcreting machine has the advantages that the delivery pipe made of the soft material is free of internal cut-off valves with wedge discs, and the cut-off device is arranged outside the delivery pipe, so that hard contact with materials is avoided, wear is reduced and the cut-off device is longer in service life.

Description

technical field [0001] The invention relates to the field of spraying equipment, in particular to a spraying machine. Background technique [0002] Shotcrete machine is mainly used for concrete engineering spraying operations such as tunnels, culverts, hydropower projects, civil air defense projects, mines, high marshes, and lanes of high-speed railways and highways and subways. [0003] Most of the current shotcrete machines use rams or other ball valve structures for conveying. Since the material conveyed by the shotcrete machine is mud, there may be stone particles, and the rams are easy to wear when they are installed in the delivery pipe, and the service life is not long. long. Contents of the invention [0004] In order to overcome the deficiencies of the background technology, the present invention designs and provides a shotcrete machine, which mainly solves the problem that the gate plate of the shotcrete machine is easy to wear and has a short service life when ...
