DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] See also Figures 1 to 4 The embodiment of the present application provides an automatic material distribution system for sintering production, including a silo 1, a shuttle material distribution vehicle 2 for distributing materials to the silo 1, a meter 3, a radar material level meter 4 and a PLC controller 5. The shuttle material distribution vehicle 2 is electrically connected to the PLC controller 5. The shuttle material distribution vehicle 2 includes a belt conveyor 21 and a walking trolley 22. The walking trolley 22 includes a driven wheel 221. The shuttle material distribution vehicle 2 is a prior art. Through the movement of the walking trolley 22, the belt conveyor 21 delivers materials to the silo 1 at different positions. The meter counter 3 includes a wheel body 31, which is rollingly connected to the driven wheel 221. There are multiple silos 1, which are arranged in a straight line. A corresponding radar level meter 4 is installed above each silo 1. The radar level meter 4 detects the material level of the silo 1. The radar level meter 4 is connected to the PLC controller 5 by communication, specifically by electrical connection; the meter counter 3 is connected to the PLC controller 5 by wireless communication, and a remote signal module 7 is set on the walking trolley 22, which has a wireless transceiver function. The meter counter 3 is connected to the PLC controller 5 by wireless communication through the remote signal module 7. The meter counter 3 is a roller type meter counter 3, model JK76.

[0020] Through the communication connection between the radar level meter 4 and the PLC controller 5, the coordinate calibration of the material distribution position of each silo 1 is realized. During operation, the system automatically detects the material level of the current silo 1 through the radar level meter 4. When the material level reaches the set value, the position of the target silo 1 is first determined, and the position of the target silo 1 is found according to the parameter control program such as the material level setting and weight built into the PLC controller 5. Then the silo change operation is started, and the walking trolley 22 is started. The walking trolley 22 moves to the target silo 1 and continues to distribute the material. After the deployment of this system, the operator changes from squatting to patrolling, and only needs to check the equipment operation status on site regularly.

[0021] After the system is put into use, it can perform fully automatic warehouse searching, warehouse changing and belt reversing operations, which improves the efficiency of material laying and reduces the labor intensity of manual work.

[0022] In a preferred embodiment, in order to facilitate the wheel body 31 to press the driven wheel 221, reduce the detection error of the meter 3, and improve the detection accuracy, please refer to Figure 3The walking trolley 22 is provided with a frame 222, and the meter meter 3 is connected to the frame 222 through a clamping mechanism 6; the clamping mechanism 6 includes a mounting frame 61, a nut 62, a screw 63, a barrel 64, a mounting plate 65, a slider 66, a guide rod 67 and an elastic member 68. The mounting frame 61 is fixedly connected to the frame 222, the mounting plate 65 is fixedly connected to the fixed end of the meter meter 3, the barrel 64 is fixedly connected to the mounting plate 65, the slider 66 is slidably installed in the barrel 64, the screw 63 is rotatably connected to the slider 66, the nut 62 is fixedly connected to the mounting frame 61, the screw 63 is threadedly connected to the nut 62, the guide rod 67 is fixedly connected to the barrel 64, and the guide rod 67 is slidably connected to the mounting frame 61. The screw 63 is rotatably connected to the slider 66 through a bearing, and a handle 69 is installed at one end of the screw 63 away from the slider 66. The meter counter 3 also includes a wheel axle 32, on which the wheel body 31 is mounted; a screw rod 63 is arranged perpendicular to the wheel axle 32, and the axis of the screw rod 63 passes through the axis of the wheel body 31 and the axis of the driven wheel 221. The elastic member 68 is a compression spring, and the axis of the screw rod 63 passes through the center of the elastic member 68.

[0023] When the mounting bracket 61 is installed on the vehicle frame 222, there is a certain distance between the wheel body 31 and the driven wheel 221, which will facilitate installation; then, by rotating the handle 69, under the action of the nut 62 and the guiding action of the guide rod 67, the screw 63 drives the slider 66 to move, and the bearing is provided to prevent the screw 63 from driving the slider 66 to rotate continuously; the slider 66 drives the elastic member 68, the cylinder 64, and the meter counter 3 to move, so that the wheel body 31 approaches the driven wheel 221 and contacts with the driven wheel 221, and then the handle 69 is continued to be rotated, so that the slider 66 squeezes the elastic member 68, and the elastic member 68 squeezes the cylinder 64 and the meter counter 3, so that the wheel body 31 presses the driven wheel 221, thereby increasing the friction between the wheel body 31 and the driven wheel 221, and avoiding the relative sliding between the wheel body 31 and the driven wheel 221 to cause detection errors.

[0024] In addition, the screw 63 is arranged perpendicular to the wheel axle 32, and the axis of the screw 63 passes through the axis of the wheel body 31 and the axis of the driven wheel 221, so that the elastic force of the elastic member 68 on the cylinder 64 and the meter 3 can be fully applied to the driven wheel 221, thereby increasing the friction between the wheel body 31 and the driven wheel 221.

[0025] By rotating the handle 69 in the reverse direction, the meter counter 3 can be driven away from the driven wheel 221, so as to facilitate replacement of the meter counter 3 or maintenance of the meter counter 3.

[0026] In a preferred embodiment, in order to improve the detection accuracy of the meter 3 and reduce the cumulative error, please refer to Figure 1 and Figure 2A travel switch 8 is arranged above one of the silos 1. The travel switch 8 is arranged in cooperation with the traveling trolley 22. When the traveling trolley 22 contacts the travel switch 8, the travel of the meter counter 3 is reset to zero. Preferably, the travel switch 8 is arranged at the silo 1 located in the center. The travel switch 8 serves as a zero mark for the travel of the traveling trolley 22. Every time the traveling trolley 22 passes the travel switch 8, the travel of the meter counter 3 is reset to zero. In this way, the cumulative error of the meter counter 3 can be reduced, so as to improve the detection accuracy of the meter counter 3.
