DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0024] The efficient and rapid verification device for actual coal of a belt scale disclosed in the utility model is mainly applied to scenarios where actual coal is likely to remain on the belt of a conventional belt scale verification device after being used for a period of time, and errors are likely to occur in the verification results during regular verification to ensure accuracy, thus affecting the use of the belt scale and the coal metering efficiency.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The belt scale coal efficient and fast verification device comprises a belt scale body 1 and a belt body 3 arranged on the belt scale body 1, and also comprises:

[0026] Collection mechanism: The collection mechanism is arranged on the belt scale body 1;

[0027] A thrust mechanism is provided on the belt body 3, and a push block 7 is provided on the thrust mechanism. A shovel block 9 is fixedly connected to the outer wall of one side of the push block 7 close to the bottom, and mounting plates 10 are fixedly connected to the outer walls on both sides of the shovel block 9. The same rotating shaft 12 is provided on the outer walls on the opposite sides of the two mounting plates 10, and a roller brush 8 is provided on the circumferential outer wall of the rotating shaft 12. First connecting rollers are provided on the outer walls on both sides of the push block 7, and a rotating wheel 11 is provided at one end of the first connecting roller. Second connecting rollers are provided on the circumferential outer walls on both sides of the rotating shaft 12, and the same synchronous belt 13 is sleeved on the circumferential outer walls of the first connecting roller and the second connecting roller.

[0028] In the specific working process, the push block 7 is pushed by the thrust mechanism. While the push block 7 pushes, the wheel 11 rotates, and the belt body 3 is transmitted synchronously. Under the action of the synchronous belt 13, the roller brush 8 is driven to rotate rapidly to clean the real coal remaining on the belt body 3. At the same time, the shovel block 9 pushes and shovels the surface of the belt body 3, and the real coal is collected by the collecting mechanism. Under the transmission of the belt body 3, all the real coal remaining on the upper and lower sides of the belt body 3 is processed, thereby solving the problem of calibration error of the belt scale body 1. According to the actual use process, an online physical weighing calibration can also be designed, and an online physical weighing calibration mechanism can be used to dynamically calibrate the factory-entry and warehouse-loading belt scale bodies 1, and the weighing data of the belt scale body 1 can be monitored and corrected in real time to solve the problem that the dynamic chain code calibration may not accurately reflect the actual coal flow.

[0029] Among them, the rotating wheel 11 and the roller brush 8 are both in contact with the belt body 3, and the ratio of the diameter of the first connecting roller to the diameter of the second connecting roller is 3:1. In this way, while the rotating wheel 11 rotates on the belt body 3, it drives the roller brush 8 to clean the real coal on the surface of the belt body 3 through the synchronous belt 13. The first connecting roller rotates one circle and the second connecting roller can rotate three circles, so that the roller brush 8 can rotate quickly and efficiently to clean the belt body 3.

[0030] Among them, the shovel block 9 is used in conjunction with the belt body 3, so that the shovel block 9 contacts the surface of the belt body 3. During the pushing process, the shovel block 9 can shovel the solid coal on the belt body 3, and then cooperate with the roller brush 8 to make the use effect of the belt scale body 1 better.

[0031] It should be noted that, in an actual feasible example, the difference method can also be used, combined with the characteristics of the coal type and the environmental conditions of the coal yard, to calculate the real-time average density of specific coal types in each area of ​​the coal yard, so as to achieve more accurate coal pile density measurement. Through measurement means, not only time and labor are saved, but also the accuracy of the data is improved, which provides strong data support for the construction of digital power plants and intelligent coal yard management.

An electric telescopic rod 6 is provided on the outer wall of one side of the connecting plate 5, and one end of the piston rod of the electric telescopic rod 6 is connected to the push block 7, and the electric telescopic rod 6 is used in conjunction with the push block 7.

[0033] Specifically, the push block 7 is pushed on the belt body 3 by the operation of the electric telescopic rod 6 , and then the entire belt body 3 is cleaned under the rotation of the belt body 3 itself.

[0034] Reference Figure 3 and Figure 4 In a preferred embodiment, the collecting mechanism includes a slide 14 opened on the outer wall of one side of the push block 7, and a collecting groove 15 is opened on the inner wall of the push block 7. The slide 14 is connected to the collecting groove 15, and the slide 14 is arranged as an inclined structure. The slotted opening of the slide 14 is flush with the position of the shovel block 9, and the collecting groove 15 is used in conjunction with the shovel block 9.

[0035] Specifically, when the collecting mechanism is working, the solid coal scooped by the shovel block 9 falls into the collecting trough 15 through the slide 14 for collection. After being used for a period of time, the push block 7 can be removed or a drawer designed in the push block 7 can be designed to draw out and clean the solid coal. The collected solid coal can also be weighed and used again.

[0037] Specifically, real coal that needs to be weighed is placed in the discharge bin 4. If the discharge bin 4 is not large enough, another bin can be added above the discharge bin 4. When the belt scale body 1 is used, the real coal in the discharge bin 4 falls onto the belt body 3 and is transmitted to the metering section position for operation. The connecting plate 5 is arranged below the discharge bin 4 so that the pushing process of the push block 7 does not affect the installation of the discharge bin 4 and the pushing is smooth.

[0038] Reference Figure 1 In a preferred embodiment, transmission rollers are provided on both sides of the inner wall of the belt scale body 1, the belt body 3 is located on the circumferential outer walls of the two transmission rollers, a motor 2 is provided on one side outer wall of the belt scale body 1, and one end of the output shaft of the motor 2 is connected to a transmission roller.

[0039] Specifically, the motor 2 drives the transmission roller to rotate, and under the action of the belt body 3, the two transmission rollers rotate synchronously, so that the belt body 3 cleans the residual solid coal during the transmission process.

[0040] Working principle: When in use, the belt body 3 is transmitted on the belt scale body 1, and the electric telescopic rod 6 works to push the push block 7, and the wheel 11 rotates at the same time. Under the action of the synchronous belt 13, the roller brush 8 is driven to rotate rapidly to clean the real coal remaining on the belt body 3. At the same time, the shovel block 9 pushes and shovels the surface of the belt body 3, and the real coal falls into the collection trough 15 through the slide 14 for collection and use, and then all the real coal remaining on the belt body 3 is processed, thereby solving the problem of calibration error of the belt scale body 1.
