Description

Technical Field

[0001] The utility model is applicable to the field of paving base material production equipment and provides a leakage-proof curbstone placing machine. Background Art

[0002] Curbstone is a demarcation material used to separate different lanes in road construction. It is generally laid between motor vehicle lanes and non-motor vehicle lanes to play a role in aesthetics and marking boundaries. In the production of curbstones, wet concrete is usually added directly from the storage bin into the curbstone mold. After the curbstone mold is filled with material, the discharge port of the storage bin is closed to stop the material discharge. However, this material discharge method relies on subjective vision or experience to control the switch, which often causes material leakage due to closing delays or squeezing of the storage bin door, resulting in waste of raw materials. At the same time, the raw material of this type of curbstone is generally a concrete mixture, which adheres to the equipment after air drying and is difficult to clean. Utility Model Content

The lifting unit 5 includes two linear lifting devices 51 and a lifting drive device 52. The linear lifting device 51 is fixedly connected to the cloth unit hanger 6. In this embodiment, the linear lifting device 51 adopts a worm gear screw lifting device. The driving shafts of the two worm gear screw lifting devices are driven and connected through a synchronous coupling 53. Any one of the two worm gear screw lifting devices is driven and connected to the lifting drive device 52. The lifting drive device 52 uses a servo motor in this embodiment to improve accuracy. At the same time, the lifting unit 5 also includes a plurality of limiting guide rods 54. The limiting guide rods 54 are slidably connected to the cloth unit hanger 6, and one end of the limiting guide rods 54 is fixedly connected to the quantitative feeding unit 4. In this way, when the worm gear screw lifting device drives the quantitative feeding unit 4 to rise and fall, it will be more stable and the quantitative feeding The feeding unit 4 is arranged below the material distribution unit hanger 6, and includes a feeding unit bracket 41 and a quantitative feeding bin 43 with upper and lower openings. The feeding unit bracket 41 is fixedly connected to the moving end of the linear lifting device 51. Several weighing sensors 42 are arranged between the feeding unit bracket 41 and the quantitative feeding bin 43. One end of the weighing sensor 42 is fixedly connected to the feeding unit bracket 41, and the other end is fixedly connected to the quantitative feeding bin 43. A feeding baffle 44 is rotatably arranged at the lower opening position of the quantitative feeding bin 43. A baffle driving device 45 is fixedly arranged on the quantitative feeding bin 43. The baffle driving device 45 is drivingly connected to the feeding baffle 44 and is used to drive the feeding baffle 44 to rotate. In this embodiment, the baffle driving device 45 adopts a linear cylinder, and the telescopic part and the fixed part of the linear cylinder are rotatably connected to the feeding baffle 44 and the quantitative feeding bin 43 respectively. The use of the linear cylinder not only has low cost, but also has a relatively fast driving speed.

[0025] The material storage unit 2 and the quantitative feeding unit 4 are connected via the material transfer unit 3. Figure 4 As shown, the material transfer unit 3 includes a material transfer pipeline 31 and a screw conveying device. A feed port 32 and a discharge port 33 are respectively provided at both ends of the material transfer pipeline 31. The feed port 32 is communicated with the material storage tank material port 22, and the discharge port 33 is arranged facing the upper opening of the quantitative feeding bin 43.

[0027] The working principle of this embodiment is as follows:

[0028] First, in the initial state, the lifting unit 5 raises the quantitative feeding unit 4 to the height of the upper opening of the quantitative feeding bin 43 close to the discharge port 33 of the material transfer pipe 31, and then the storage tank body 21 begins to feed materials into the material transfer pipe 31 through the storage tank feed port 22. At this time, the screw conveyor shaft 34 begins to transport the material from the feed port 32 to the discharge port 33 by rotation, and then discharges the material into the quantitative feeding bin 43 through the discharge port 33. The weighing sensor 42 of the quantitative feeding unit 4 continuously monitors the weight of the material in the quantitative feeding bin 43. Once the amount of material production is reached, the screw conveyor shaft 34 stops rotating, and the material transfer unit 3 also stops discharging. At this time, the lifting unit 5 lowers the quantitative feeding unit 4 to the feeding position of the lower opening of the quantitative feeding bin 43 close to the curbstone mold 7 below. At this time, the feeding baffle 44 is driven to rotate to open the lower opening, and then the quantitative feeding bin 43 begins to feed the curbstone mold 7 until the feeding is completed and returns to the initial position to prepare for the next feeding.
