[0026] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0027] In the description of the utility model, it should be pointed out that the directions or position relations indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end" and "the other end" are based on the directions or position relations shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0028] The utility model is a kind of road and bridge construction concrete distributing machine, for the distribution of concrete in road and bridge construction, and preliminary leveling construction is carried out after distribution.

[0029] As Figure 1 Shown, the distributing machine includes main beam 1, distributing trolley and flat material pushing device. Walking assembly is arranged at the both ends of main beam 1, and main beam 1 is driven to move longitudinally by walking assembly. The distributing trolley is arranged on main beam 1, and can move along the transverse length direction of main beam 1. The transverse movement of distributing trolley realizes the distribution of concrete in transverse position. Walking assembly is a conventional setting in the field, mainly including walking seat, longitudinal walking wheel 3 and motor. The both ends of main beam 1 are connected with walking seat, and motor drives longitudinal walking wheel 3 to rotate and move. In specific implementation, the walking assembly of main beam 1 is motor-driven rubber wheel that rolls.

[0030] Further, main beam 1 is installed on walking assembly by lifting rod 8 on both sides. Specifically, lifting rod 8 is fixed on walking seat, and the both ends of main beam 1 are fixedly connected with the lifting end of lifting rod 8. The main beam can be adjusted in whole, and is adjusted according to needs when the thickness of distribution is different.

[0031] Flat material pushing device is arranged at the rear side of the forward direction of main beam 1, that is, located at the rear of the working cross section of distributing trolley, and is used for the preliminary leveling of concrete.

[0032] As Figure 1 , Figure 2As shown, the main cross beam 1 has a certain width, a rectangular frame structure, and the cloth trolley is arranged on the frame structure. Specifically, the cloth trolley includes a cloth bin 4 and a power assembly. The cloth bin 4 has a large opening at the top and a closed bottom. The cloth trolley further includes a moving frame arranged on the main cross beam 1, and a motor-driven roller is arranged on the moving frame as the power assembly. The cloth bin 4 is horizontally moved under the cooperation of the power assembly and the moving frame. The main body of the cloth bin 4 is located below the upper surface of the main cross beam 1.

[0033] A bin door 5 is arranged at the bottom of the cloth bin 4, and the opening and closing degree of the bin door 5 can be controlled as needed. The falling amount of concrete is controlled by controlling the opening and closing degree of the bin door 5, so as to control the thickness of the concrete distribution.

[0034] The cloth bin 4 of the distribution machine is used to buffer and control the distribution speed of the concrete. The lower end of the cloth bin 4 is a discharge port, and a bin door 5 is arranged at a position corresponding to the discharge port. Specifically, the discharge port is horizontal, and the bin door 5 is horizontally arranged and horizontally moved. The bin door 5 is usually arranged as a rectangular plate. A chute is arranged on both sides of the discharge port, and the bin door 5 slides in the chute. A push rod 2 is fixedly arranged on one side. The fixed end of the push rod 2 is in a fixed state, and the outer end of the moving rod is fixedly connected with the bin door 5. The lower part of the cloth bin 4 is fixedly arranged with a frame body for mounting the push rod 2. The moving rod of the push rod 2 is telescopic to realize the position movement of the bin door 5, thereby realizing the control of the opening and closing degree of the bin door 5 on the discharge port. Specifically, as shown in the figure, Figure 2 、 Figure 3 as shown, Figure 3 in the figure, Figure 2 one of the connecting beams above the bin door 5 on the moving frame is hidden, which is convenient for observing the bin door.

[0035] In a specific implementation, the push rod 2 is an electric push rod or a hydraulic push rod.

[0036] An attached vibrator is mounted on the outer wall of the cloth bin 4. During work, the attached vibrator 10 is always in a vibrating state, which can prevent the concrete from blocking the discharge port and prevent the concrete from sticking to the wall. Two attached vibrators 10 are arranged on the two opposite outer sides of the bin door 5.

[0037] The distribution machine is provided with a flat material pushing device to initially level the concrete material. Because the concrete at some positions is in a piled-up state after being distributed by the cloth trolley, it needs to be initially leveled.

[0038] The flat material pushing device can be directly arranged as a spiral auger 6, and the spiral auger 6 is driven to rotate by a motor. The spiral auger 6 transports the concrete at uneven positions.

[0039] Alternatively, the material pushing device can be provided as a material leveling trolley 9. Preferably, the material leveling trolley 9 is directly fixed behind the material distributing trolley. A rotatable material scraper 7 is arranged at the lower part of the material leveling trolley 9. After the material distributing trolley distributes the material, the material leveling trolley 9 directly scrapes and levels the concrete on the construction surface. The material leveling trolley 9 comprises a trolley frame, the material scraper 7 and a motor. The trolley frame is directly fixed to the material distributing trolley. The motor and the material scraper 7 are arranged at the lower part of the trolley frame. The motor drives the material scraper 7 to rotate 360° to scrape and level the material. Details are shown in Figure 4 、 Figure 5 .

[0040] The material distributing machine sets the number of material distributing trolleys according to the width of the construction surface, and usually sets 1-3 material distributing trolleys. When the width of the bridge surface is greater than 19.5 meters, two material distributing trolleys can be arranged to improve the work efficiency.

[0041] The longitudinal movement of the whole machine and the transverse movement of the material distributing trolley are adjusted by the frequency conversion of the driving motor.

[0042] When the material distributing machine is used, a concrete tank truck or other concrete filling equipment is needed to be used in combination. The concrete filling equipment fills the concrete into the material distributing trolley to ensure the continuous supply of the concrete. Details are shown in Figure 4 .

[0043] The material distributing machine adopts the material distributing trolley and the material pushing device to distribute the material, which can immediately level the material after the material is dropped, thereby facilitating the subsequent fine leveling construction of the concrete pavement.

[0044] The above shows and describes the basic principles and main features of the material distributing machine and the advantages of the material distributing machine. It should be understood by those skilled in the art that the material distributing machine is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the material distributing machine. Without departing from the spirit and scope of the material distributing machine, the material distributing machine can have various changes and improvements, and these changes and improvements all fall within the scope of the claimed material distributing machine.
