[0020] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0021] like Figures 1 to 3 As shown, the cement clinker unloading device comprises a warehouse 1, a track 2 is arranged above the warehouse 1, a trolley 3 is arranged on the track 2, a wheel 7 is arranged at the bottom of the trolley 3, a material conveying belt 4 is arranged on the trolley 3, a material unloading belt 5 is arranged below one end of the material conveying belt 4, a warehouse 1 is arranged below the material unloading belt 5, and a material quantity detection device is arranged at the end of the material unloading belt 5. The wheel 7 is driven by a motor to realize the horizontal operation of the trolley 3 on the track 2, the material conveying belt 4 receives the incoming material mechanism and lifts the material to a suitable height, the material unloading belt 5 transports the material to the top of the warehouse opening 12, and the measuring radar 6 as a material quantity detection device can judge whether the material in the warehouse 1 is full.

[0022] like Figures 1 to 3 As shown, the material quantity detection device includes a measuring radar 6, and a warehouse opening 12 is provided at the top of the warehouse 1, and the measuring radar 6 is located above the warehouse opening 12. The fixed-point and quantitative distribution of materials is realized by the measuring radar 6 and the PLC control system. Four measuring radars 6 are set at the unloading port. The millimeter wave imaging radar identifies the point cloud data of the material in the warehouse opening 12 area of ​​the warehouse body, and calculates the volume of the material in the warehouse body below through the point cloud data, and then obtains the material quantity. Therefore, the material quantity of the corresponding warehouse position can be recorded in real time, and the trolley 3 can be controlled to run automatic material distribution according to the material situation of the warehouse position.

[0023] The measuring radar 6 is a millimeter-wave radar, which has the advantages of high detection accuracy, high resolution, all-weather operation and strong anti-interference ability; the millimeter-wave imaging radar can generate high-resolution images, can provide more accurate target position and shape information, and facilitate the operator to make remote judgments; the millimeter-wave imaging radar is not affected by weather conditions and can work normally in any weather conditions or complex electromagnetic environments, thus meeting the operational requirements of production line operation.

[0024] like Figure 2 As shown, the unloading belt 5 is arranged perpendicular to the track 2, and the transport belt 4 is arranged obliquely; the unloading belt 5 is arranged symmetrically about the track 2, and the warehouse openings 12 are arranged in pairs. The inclined transport belt 4 is used to transport the material to a suitable height, and the unloading belt 5 is arranged horizontally, which can stably transport the material to the warehouse opening 12. In order to further improve the material unloading efficiency, the unloading belt 5 is divided into two conveying directions by the forward and reverse drive of two motors, and two warehouse openings 12 are opened on the warehouse 1. After the material falls from the transport belt 4 to the middle of the unloading belt 5, the material enters the warehouse 1 from the two warehouse openings 12 after diversion. Accordingly, there are two unloading points in the warehouse 1, and the warehouse 1 can be filled faster, avoiding the situation where the material accumulates at a single unloading point and causes redundant space in the warehouse 1.

[0025] like Figure 1As shown, a dust cover 8 is provided above the unloading belt 5, and the end of the conveying belt 4 extends into the dust cover 8. Since the material dropping area is from the end of the conveying belt 4 to the middle of the unloading belt 5, the dust cover 8 is designed at this position to reduce the diffusion of material dust during the transportation process, reduce environmental pollution and improve operation safety.

[0026] like Figure 1 As shown, the trolley 3 includes a frame 9, on which a conveying belt roller 10 and a material discharge belt roller 11 are provided, the conveying belt 4 is provided on the conveying belt roller 10, and the material discharge belt 5 is provided on the material discharge belt roller 11. The above-mentioned rollers provide reliable support for the conveying belt and the transported materials, reduce the impact or movement of the materials on the belt during the material dropping and transportation, reduce the loss of materials during the transportation process, and reduce the cost; at the same time, it also reduces the friction of the conveying belt operation, which can extend its service life.

[0027] like Figure 3 As shown, the warehouses 1 are arranged at equal intervals, and pedestrian corridors are provided on both sides of the warehouses 1. The warehouses 1 are arranged in sequence to match the extension direction of the track 2, which can reduce the space occupied by the warehouses 1, and the pedestrian corridors can facilitate personnel to view from the outside.

[0028] like Figure 1 and Figure 3 As shown, the measuring radars 6 are arranged in pairs. A plurality of measuring radars 6 can further improve the measurement accuracy.

[0029] The operation process is as follows: 1. During the operation of the trolley 3, it runs horizontally along the track 2. The operation time of the trolley 3 is controlled by the PLC signal. When the trolley 3 reaches a certain unloading bin 12, the belt transports the material through the transverse belt to complete the transportation of the material to different bins.

[0030] 2. The four measuring radars 6 at the unloading port of the trolley 3 can scan the accumulation of materials under the bin port 12, and calculate the material quantity corresponding to the unloading bin port 12 through the scanning data. When the material quantity reaches a certain requirement, the signal is transmitted to the PLC control system, and the PLC control system will send an operation signal to the trolley 3, and the trolley 3 will run to the next unloading bin port 12 for material distribution, thereby realizing fixed-point and quantitative distribution of materials.

[0031] 3. The transverse belt motor controls the direction of material discharge by forward and reverse rotation. The warehouse opening 12 corresponds to the discharge opening, so that the measuring radar 6 below can effectively scan the material pile at the warehouse opening 12 to achieve accurate material quantity calculation.

[0032] The cement clinker unloading device replaces the current manual inspection judgment method by setting a measuring radar 6. The measuring radar 6 uses point cloud data to judge whether the warehouse 1 is full, ensuring that the inventory of the warehouse 1 meets the standard, avoiding the situation that the inventory does not meet the standard or the unloading overflows, realizing the fixed-point and quantitative distribution of materials, ensuring the smooth progress of subsequent production, and at the same time reducing the labor intensity of personnel and having high operation safety; the unloading belt 5 can divert the material and improve the unloading efficiency, and the rollers can reliably support the conveyor belt, reducing the loss of materials during the unloading process.

[0033] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
