[0002] Curbstones are road marking stones used to mark road boundaries and are often used to isolate different roads. In the production of curbstones, the mixed wet concrete is usually directly put into the curbstone mold from the storage bin. This feeding method cannot accurately control the feeding amount. Too little feeding will result in a product that does not meet the requirements, and too much feeding will cause waste. At the same time, in order to ensure the size of the finished product, it is also necessary to spend time cleaning up the excess wet material, further increasing the production cost.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] For example, see the attached Figure 1 The utility model provides an automatic kerbstone placing machine with accurate feeding, comprising a main frame 1, a material storage unit 2 is fixedly arranged on the upper part of the main frame 1, as shown in the attached Figure 2 As shown, the storage unit 2 includes a storage tank 21, a discharge port 22 is provided at the bottom of the storage tank 21, a material stirring device is provided in the storage tank 21, the material stirring device includes a stirring paddle 23 and a stirring drive motor 24, the distance between the lower end surface of the stirring paddle 23 and the inner bottom surface of the storage tank 21 is less than 10 mm, and a small distance is directly provided between the lower end surface of the stirring paddle 23 and the inner bottom surface of the storage tank 21 so that the material can be conveniently pushed into the discharge port 22 while stirring the material. A vibration motor 25 is fixedly provided on the outer wall of the storage tank 21, and the vibration motor 25 can improve the wall adhesion of the material, and avoid the residual solidification of the material on the inner wall of the storage tank 21 after long-term use, which is difficult to clean; a precise unloading unit 3 is provided at the lower end of the discharge port 22, as shown in the attached Figure 3 The material discharging device 33 is used to drive the material discharging baffle 32 to rotate. Figure 4As shown, the quantitative feeding unit 4 includes a feeding unit bracket 41, which is slidably arranged on the material distribution moving track 5, and the main frame 1 is provided with a feeding unit driving device 46. In this embodiment, a linear driving cylinder is used as the feeding unit driving device 46, and the feeding unit driving device 46 is drivingly connected to the feeding unit bracket 41, and is used to drive the feeding unit bracket 41 to reciprocate along the material distribution moving track 5. A plurality of weighing sensors 42 are fixedly arranged on the upper end of the feeding unit bracket 41, and a quantitative feeding bin 43 is fixedly arranged on the upper end of the weighing sensor 42. In this way, the quantitative feeding can be monitored at any time. The weight of the material in the silo 43, the quantitative feeding silo 43 is provided with an upper feeding port and a lower feeding port, the quantitative feeding silo 43 is rotatably provided with a feeding silo door 44 at the position of the lower feeding port, the quantitative feeding silo 43 is provided with at least one feeding drive device 45, the feeding drive device 45 is drivingly connected to the feeding silo door 44, and is used to drive the feeding silo door 44 to rotate. In this embodiment, a linear drive cylinder is used as the feeding drive device 45, and the number is two. When the two linear drive cylinders jointly drive the feeding silo door 44, it is more stable. When one of them fails, the other can temporarily complete the driving work alone.

[0021] The working principle of this embodiment is as follows:

[0022] The materials used for the production of curbstones are stored in the storage tank 21. During the production process, the material stirring device continuously stirs the materials in the storage tank 21 to prevent them from solidifying. At the beginning of production, the upper feed port of the quantitative feeding bin 43 is controlled to be aligned with the lower opening of the lower feeding bin 31. At this time, the lower feeding baffle 32 is controlled to rotate to leave the lower opening of the lower feeding bin 31. At this time, the materials in the lower feeding bin 31 are transferred to the quantitative feeding bin 43 under the action of gravity. During this process, the weighing sensor 42 continuously monitors the weight change in the quantitative feeding bin 43. When the weight of the materials in the quantitative feeding bin 43 is close to the weight of the materials required for one curbstone production (in actual application, it reaches about 95% of the weight of the materials required for one curbstone production), the lower feeding baffle 32 is controlled to start to intermittently block the lower opening of the lower feeding bin 31. At this time, the unloading bin 31 will begin to intermittently unload a small amount of material into the quantitative feeding bin 43. In this way, after each small amount of unloading, there is a gap to accurately judge whether the material in the unloading bin 31 meets the specified requirements through the weighing sensor 42. If the requirements are met, a stop command will be issued before the next unloading begins. At this time, the unloading baffle 32 will stop rotating, and then the unloading bin 31 will stop unloading. If the requirements are not met, the next unloading will continue until the requirements are met. Compared with the continuous unloading in the past, this unloading method has more accurate control over the material quantity in the quantitative feeding bin 43, improves the final quality of the product, and also avoids material waste; and when the material in the quantitative feeding bin 43 is filled, the quantitative feeding bin 43 is driven by the feeding unit driving device 46 to move to the outside of the main frame 1 for production feeding.
