Description

Technical Field

[0001] The utility model relates to the technical field of mortar recovery, in particular to a mortar recovery unit of horizontal shotcrete equipment. Background Art

[0002] Horizontal spraying machine is a widely used equipment in construction, mainly used for concrete spraying. When the plunger or rotor moves, the concrete in the hopper will be sucked in and compressed, and then the concrete will be sprayed to the location where construction is required through the delivery pipe and nozzle. Horizontal spraying machine usually adopts horizontal design, and the rotor cavity and its central rotating shaft are horizontally set, which is conducive to the smooth flow and spraying of concrete. Horizontal spraying machine is widely used in concrete spraying operations of various houses, bridges, tunnels, underground projects, etc. in construction projects.

[0003] During the production of steel tube concrete pipes, a horizontal spraying machine is required to spray cement mortar on the pipe body. Since the existing horizontal spraying device lacks a corresponding mortar recovery unit and an anti-splashing structure, mortar splashes when spraying cement mortar on the pipe body, and mortar accumulates around the spraying device. Therefore, manual cleaning and recovery are required, which increases the labor intensity of workers. Utility Model Content

[0004] The utility model aims to provide a mortar recovery unit for horizontal shotcrete equipment to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mortar recovery unit of a horizontal shotcrete equipment comprises a fixed table, both ends of the top of the fixed table are fixedly connected to support seats, a recovery box is arranged on the top of the fixed table, the bottom of the recovery box is rotatably connected to a hinged column fixedly connected to the fixed table, discharge pipes are fixedly connected to opposite side walls of the recovery box, one end of the bottom of the recovery box is fixedly connected to a box body, a dual-axis motor is fixedly connected to the interior of the box body, and eccentric blocks are fixedly sleeved on both side output ends of the dual-axis motor.

[0007] Furthermore, the recovery box is composed of two symmetrical inclined plates.

[0008] Furthermore, four connection blocks are symmetrically fixedly connected to the bottom of the recovery box, and the bottom of the connection block is fixedly connected to a shock-absorbing spring fixedly connected to the fixing platform.

[0009] Furthermore, a positioning plate is fixedly connected between the two support seats, a slide rail is fixedly arranged on the top of the positioning plate, a slide seat is slidably connected to the slide rail, and a horizontal shotcrete machine is fixedly arranged on the slide seat.

[0010] Furthermore, a driving motor is fixedly connected in the support seat, a rotating drum is fixedly connected to the output end of the driving motor, a hydraulic cylinder is fixedly connected to the inner wall of the rotating drum, a moving block is fixedly connected to the end of the hydraulic cylinder, one end of four linkage rods is rotatably connected to the moving block, the other ends of the four linkage rods are rotatably connected to sliding columns slidably connected to the rotating drum, and the ends of the sliding columns are fixedly connected to inner support plates.

[0011] Furthermore, two fixed columns are fixedly connected to the fixed platform, a rotating column is rotatably connected between the two fixed columns, a baffle is fixedly connected to the outer wall of the rotating column, one end of two cylinders is rotatably connected to the outer wall of the baffle, the other ends of the two cylinders are rotatably connected to a connecting plate fixedly connected to the fixed platform, and a baffle is fixedly connected to the top of the baffle.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. After the steel cylinder concrete pipe is placed on two rotating drums for positioning, the driving motor can drive the steel cylinder concrete pipe to rotate, and at the same time, the slide seat drives the horizontal spraying machine to perform mobile spraying of mortar on the surface of the steel cylinder concrete. Since the steel cylinder concrete pipe is sprayed with mortar during the continuous rotation process, the mortar can be evenly sprayed on the entire outer surface of the steel cylinder concrete pipe. During spraying, the mortar splashed or dripped from the steel cylinder concrete pipe will fall into the recovery box at the bottom. The recovery box is composed of two symmetrical inclined plates, and the whole is inclined. At the same time, the eccentric blocks on both sides are driven to rotate by the double-axis motor, so that the end of the recovery box with a higher horizontal position can be driven to vibrate continuously, so that the mortar collected in the recovery box will flow along its surface, and finally the collected mortar can be discharged through the discharge pipe, thereby improving the recovery efficiency after spraying mortar and reducing the labor intensity of workers.

[0014] 2. After the steel cylinder concrete pipe is positioned, the cylinder is extended to drive the shield to rotate between the two fixed columns until the shield can cover the steel cylinder concrete pipe. Thus, the mortar spilled during the rotation of the steel cylinder concrete pipe will be blocked by the shield. Since the inner wall of the shield is an arc-shaped surface, the mortar will flow along the arc-shaped surface and drip into the recovery box, thereby increasing the recovery amount of the mortar and preventing the working environment from being affected by the mortar.

Since the steel cylinder concrete pipe is sprayed with mortar during the continuous rotation process, the mortar can be evenly sprayed on the entire outer surface of the steel cylinder concrete pipe. During spraying, the mortar splashed or dripped from the steel cylinder concrete pipe will fall into the recovery box 301 at the bottom. The recovery box 301 is composed of two symmetrical inclined plates, and the whole is inclined. At the same time, the eccentric blocks 308 on both sides are driven to rotate by the dual-axis motor 307, so that the end of the recovery box 301 with a higher horizontal position can be driven to vibrate continuously, so that the mortar collected in the recovery box 301 will flow along its surface, and finally the collected mortar can be discharged through the discharge pipe 304, thereby improving the recovery efficiency after spraying mortar and reducing the labor intensity of workers.
