[0002] A concrete placing device is a type of concrete construction equipment, which is mainly used to transport concrete to the pouring site. It is usually composed of a steel structure support, a conveying mechanism, a concrete storage hopper and an electrical control system. The concrete placing machine can accurately distribute concrete according to the size and shape of precast components. In addition, the concrete placing device can also be adjusted and adjusted according to the specifications and shapes of different precast concrete components, and has high flexibility and adjustability.

[0003] At present, during the use of a concrete placing device, it is usually necessary to place a mold on a conveying mechanism, and then the mold moves with the conveying mechanism to the bottom of the concrete storage hopper, and the concrete in the concrete storage hopper is filled into the mold, thus completing the concrete placing work. The main problem is that when the mold reaches the bottom of the concrete storage hopper, it is necessary to control the conveying mechanism to stop running, and then control the concrete in the concrete storage hopper to fall and fill into the mold. After the mold is filled with concrete, the conveying mechanism is controlled to operate and transport the mold. In this way, workers are required to frequently control the opening and closing of the conveying mechanism, and also to frequently control the concrete storage hopper to unload materials. The operation is cumbersome, and it is difficult to ensure the continuity of the concrete placing work, thereby affecting the efficiency of concrete placing. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a concrete placing device for a concrete pump, comprising a base, a bracket, a roller electric conveyor belt, a storage box, a feed pump, a discharge port, a connecting plate and a wedge block, wherein the base is installed with a bracket, the roller electric conveyor belt is installed on the bracket, two connecting plates, one in front and one in the back, are connected to the top of the bracket, a storage box is installed between the two connecting plates, a feed pump is installed on the top of the storage box, the feed pump is connected to the storage box through a pipeline, two discharge ports, one in front and one in the back, are installed on the lower left side of the storage box, a material blocking mechanism is provided on the discharge port, and a plurality of wedge blocks are evenly spaced and installed on the roller electric conveyor belt.

[0006] Preferably, the material blocking mechanism includes a baffle, a spring and a guide rod. A guide rod is installed on the top of the discharge port, and a baffle is slidably connected to the guide rod. The baffle can block the discharge port. A spring is sleeved on the guide rod, and the spring is connected to the baffle and the guide rod.

[0007] Preferably, a scraper is also included. The scraper is installed on the top of the bracket and is located on the left side of the discharge port.

[0008] Preferably, a collecting frame is also included. The collecting frame is installed on the top of the base and is located below the scraper.

[0009] Preferably, a guide plate is also included, and two guide plates are installed obliquely on the inner wall of the bracket, one in front and one in the back.

[0010] Preferably, it also includes a motor and a spiral stirring rod. The motor is installed on the top of the storage box, the spiral stirring rod is connected to the output shaft of the motor, the spiral stirring rod is located inside the storage box, and the spiral stirring rod is rotatably connected to the storage box.

[0011] Preferably, a receiving plate is also included, and the receiving plate is installed on the left side of the bracket.

[0012] The beneficial effect of the utility model is that by adding a material blocking mechanism and a wedge block, the operation of the roller electric conveyor belt is controlled to drive the mold and the wedge block to move to the left. When the wedge block touches the baffle, the baffle will be pushed upward and the spring will be compressed to open the discharge port. At this time, concrete flows into the mold from the discharge port. When the wedge block is out of contact with the baffle, the baffle is reset to the initial position under the action of the spring, thereby blocking the discharge port to prevent concrete from flowing out. In this way, the mold can be filled with concrete without stopping moving, so that workers do not need to repeatedly switch the device on and off, thereby enhancing the continuity of concrete spreading work and improving the work efficiency of concrete spreading.
