Embodiment Construction
[0035] The embodiment 1 of hopper is as Figure 6 Shown: including the concrete hopper 22 and the quick-setting agent hopper 23 installed on the corresponding hopper seat 27, the quick-setting agent hopper 23 is fixedly connected in the concrete hopper 22, and the quick-setting agent hopper 23 has a discharge end extending into the concrete hopper 22 And the quick-setting agent feeding channel for adding the powder quick-setting agent to the corresponding rotor cavity 33 . The discharge end of the quick-setting agent feeding channel corresponds to the upper cavity of the corresponding single rotor material cavity. In other embodiments of the hopper, the quick-setting agent hopper 23 can also be fixedly connected to the outside of the concrete hopper 22 . 27-1 represents the concrete feed hole among the figure.
[0036] Example 2 of the hopper as Figure 8~9 Shown: The difference from the first embodiment of the hopper is that the concrete sprayer is a split combined concret...

The invention relates to a concrete spraying machine, which comprises a frame and a rotor body, wherein the rotor body is assembled on the frame in a rotating manner and enables a rotation axial line to extend in the vertical direction, a plurality of rotor material cavities are uniformly distributed in the circumferential direction in the rotor body, the frame comprises a hopper seat which is hermetically matched with the upper end surface of the rotor body and a concrete hopper mounted on the hopper seat, a normal pressure feeding area which is communicated with the outside atmosphere and used for setting a concrete feeding hole correspondingly communicated with the concrete hopper is arranged on the hopper seat, the normal pressure feeding area comprises a feeding region which corresponds to the position of the rotor material cavity which is not full in the rotation direction of the rotor body, a quick-setting agent feeding channel for adding powder quick-setting agent into the corresponding rotor material cavity is mounted on the frame, and a quick-setting agent feeding hole corresponding to the discharge end of the quick-setting agent feeding channel is further arranged on the hopper seat in the feeding region. The invention provides the concrete spraying machine which can add the powder quick-setting agent into each corresponding rotor material cavity under normal pressure state.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method for adding a powder quick-setting agent and a hopper and a concrete sprayer for implementing the method. Background technique [0002] Existing concrete spraying machines consist of many structural forms, among which the positive pressure straight-through rotor body spraying machine is the main one. According to the combination form of the concrete hopper, the through-rotor body sprayer mainly includes the integral vibrating concrete sprayer and the split combined concrete sprayer. [0003] The structure of the integral vibrating concrete sprayer is as follows: figure 1 As shown, it includes a frame 18 and a rotor body 3 whose rotation axis is rotatably assembled on the frame 18 and extends in the up and down direction. 19. A concrete hopper 1 is installed on the hopper seat 2, and a vibrating motor 6 is connected to the concrete hopper 1 through transmis...
