[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The belt conveyor is a device that measures the mass of materials while conveying them. Its weighing principle is similar to that of a static platform scale, and it uses a weighing sensor and a scale frame to measure the mass. In the related art, the belt conveyor generally includes a conveying mechanism and a scale frame. The conveying mechanism includes a conveying frame and a belt located above the conveying frame. The scale frame is welded by a crossbeam and a longitudinal beam. The extension direction of the longitudinal beam is parallel to the extension direction of the belt. The scale frame is arranged at the lower part of the belt. A plurality of support frames are arranged on the scale frame. The support frame is provided with a roller that contacts the lower part of the belt. The upper part of the scale frame is provided with a first support beam and a second support beam. The first support beam and the second support beam are arranged parallel and spaced along the extension direction of the belt. The first support beam and the second support beam are both fixedly connected to the conveying frame. The first support beam and the second support beam are both provided with a detection device. Each detection device includes a sensor and a pull rod, which is connected to the scale frame through the pull rod so that the scale frame is suspended at the lower part of the conveyor. When in use, the belt drives the material on it to move. In the process of passing through the scale frame, the sensors of each detection device can obtain the mass of the material on the belt at this time by detecting the tension of the pull rod.

[0052] However, in the related art, the scale frame is welded by horizontal beams and longitudinal beams. After welding, the scale frame has internal stress. During use, the scale frame is prone to deformation, causing each pull rod to be subjected to different forces, resulting in insufficient detection accuracy.

[0053] Accordingly, in response to the above-mentioned technical problems, an embodiment of the present application provides a belt conveyor device, in which the scale frame is configured as a detachable structure. Compared with the scale frame formed by welding, during use, internal stress is avoided inside the scale frame to prevent deformation of the scale frame, thereby improving the detection accuracy.

[0054] See also Figure 1-3 , Figure 1 A structural schematic diagram of a belt conveyor device is provided for an embodiment of the present application; Figure 2 An exploded diagram of a belt conveyor device is provided for an embodiment of the present application; the belt conveyor device provided in the embodiment of the present application comprises: a scale frame 10, a first support beam 20, a second support beam 30 and a conveying mechanism 40, wherein:

[0055] The conveying mechanism 40 includes a conveying frame 410 , a belt 420 located above the conveying frame 410 , and a support frame 430 . The support frame 430 is supported at the lower part of the belt 420 , and has a roller 432 on the support frame 430 that contacts the belt 420 .

[0056] The conveyor frame 410 serves as the basis of the belt 420 conveying device and is used to carry the entire belt 420 conveying device; illustratively, the conveyor frame 410 may include a first bottom beam 411 and a second bottom beam 412 that are parallel and spaced apart, and the extension direction of the first bottom beam 411 and the second bottom beam 412 is parallel to the extension direction of the belt 420. Specifically, the first bottom beam 411 and the second bottom beam 412 may be cut from I-beams or channel steels. A plurality of support rods may be provided on the side of the first bottom beam 411 and the second bottom beam 412 facing the ground, one end of the support rod is fixedly connected to the first bottom beam 411 or the second bottom beam 412, and the other end is fixed to the ground, and the entire conveyor frame 410 may be lifted off the ground by the support rods.

[0057] Of course, the conveying frame 410 can also be a rectangular frame welded from structural steel, and the rectangular frame has load-bearing capacity.

[0058] The support frame 430 is arranged between the belt 420 and the conveyor frame 410. The support frame 430 can be a support frame welded with angle steel. The number of support frames 430 can be determined according to the load conditions, which is not required in the embodiment of the present application. The support frame 430 is provided with rollers 432, and there can be multiple rollers 432; for example, there can be three rollers arranged on each support frame, the axis of the roller located in the middle is parallel to the horizontal plane, and the center lines of the rollers located on both sides are inclined relative to the horizontal plane, so that the multiple rollers 432 form an inner concave structure, so that the rollers 432 fit the belt 420, and the rollers 432 rotate with the transmission direction of the belt 420. The rollers 432 provide support for the belt 420 and reduce the friction of the belt 420 during the transmission process.

[0059] Furthermore, the conveying mechanism 40 also includes a driving device and a tensioning device. The driving device provides power for the belt 420 transmission, and specifically may include a motor, a reduction gear transmission mechanism, a driving wheel and a driven wheel. Specifically, the motor may be fixedly mounted on the conveying frame 410, and the output end of the motor is connected to the input end of the reduction gear transmission mechanism. The reduction gear transmission mechanism includes large and small gears with different numbers of teeth, and the output end of the reduction gear transmission mechanism is connected to the driving wheel. The driven wheel may also be mounted on the conveying frame 410 and may rotate on its own. The driving wheel and the driven wheel are in contact with the belt, and the belt transmission is driven by the friction force.

[0060] When working, the output shaft of the motor drives the reduction gear transmission mechanism, driving the driving wheel of the belt 420 to rotate and thus realize the transmission of the belt 420; the function of the tensioning device is to keep the conveyor belt at the necessary initial tension to prevent it from slipping on the transmission roller and to ensure that the verticality of the conveyor belt between the rollers 432 is within the specified range. The tensioning device can be a spiral type, a trolley weight type, a vertical weight type, etc.

[0061] The scale frame 10 includes a first longitudinal beam 110, a second longitudinal beam 120 and a cross beam 130. The extension direction of the first longitudinal beam 110 and the second longitudinal beam 120 is parallel to the extension direction of the belt 420. The cross beam 130 is detachably connected to the first longitudinal beam 110 and the second longitudinal beam 120; the support frame 430 is detachably connected to the scale frame 10.

[0062] The weighing frame 10 is used to support the supporting frame 430. In the implementation mode in which the conveying frame 410 includes a first bottom beam 411 and a second bottom beam 412, the weighing frame 10 can be arranged between the first bottom beam 411 and the second bottom beam 412, and the top end of the weighing frame 10 is located in the space formed by the first bottom beam 411 and the second bottom beam 412. Of course, the top surface of the weighing frame 10 can also be located inside or outside the space formed by the first bottom beam 411 and the second bottom beam 412.

[0063] Furthermore, the cross beam 130 is located between the first longitudinal beam 110 and the second longitudinal beam 120. For example, the cross beam 130 may be perpendicular to the first longitudinal beam 110 and the second longitudinal beam 120. Of course, the cross beam 130 may have other angles with the first longitudinal beam 110 and the second longitudinal beam 120, and this embodiment does not limit this.

[0064] The cross beam 130 and the first longitudinal beam 110 and the second longitudinal beam 120 can be cut from channel steel, I-beam or other steel sections, or welded from steel plates. The number of cross beams 130 can be set according to load conditions, such as the first cross beam 135 and the second cross beam 136 can be arranged at intervals in the extending direction of the first longitudinal beam 110 and the second longitudinal beam 120.

[0065] In this embodiment, the cross beam 130 is detachably connected to the first longitudinal beam 110 and the second longitudinal beam 120. For example, the cross beam 130 can be screwed to the first longitudinal beam 110 and the second longitudinal beam 120. Figure 3 , Figure 4As shown, taking the cross beam 130 including the first cross beam 135 and the second cross beam 136 as an example, one end of the first cross beam 135 has a first connecting plate 131, and the other end of the first cross beam 135 has a second connecting plate. Specifically, the first connecting plate 131 and the second connecting plate can be cut from steel plates with a certain strength, and the first connecting plate 131 and the second connecting plate can be welded to the two ends of the first cross beam 135, or can be fastened to the two ends of the first cross beam 135 by bolts. The first connecting plate 131 is attached to the side of the first longitudinal beam 110 facing the second longitudinal beam 120, and the first connecting plate 131 and the first longitudinal beam 110 are connected by a first fastening bolt 151; the second connecting plate is attached to the side of the second longitudinal beam 120 facing the first longitudinal beam 110, and the second connecting plate and the second longitudinal beam 120 are connected by a second fastening bolt 152, wherein the number of the first bolt 151 and the second bolt 152 can be set to one or more according to the load conditions. Through the above arrangement, the first cross beam 135 is reliably connected between the first longitudinal beam 110 and the second longitudinal beam 120 , while achieving the effect of convenient assembly and disassembly.

[0066] Similarly, one end of the second cross beam 136 has a third connecting plate 133, and the other end of the second cross beam 136 has a fourth connecting plate. The third connecting plate 133 is in contact with the side of the first longitudinal beam 110 facing the second longitudinal beam 120, and the third connecting plate 133 and the first longitudinal beam 110 are connected by a third fastening bolt 153; the fourth connecting plate is in contact with the side of the second longitudinal beam 120 facing the first longitudinal beam 110, and the fourth connecting plate and the second longitudinal beam 120 are connected by a fourth fastening bolt 154.

[0067] In the embodiment of the detachable connection between the cross beam 130 and the first longitudinal beam 110 and the second longitudinal beam 120, it can also include: mortise holes are opened on the side of the first longitudinal beam 110 and the second longitudinal beam 120 facing the cross beam, and tenons are provided at both ends of the cross beam 130. During installation, the tenons are inserted into the corresponding mortise holes, thereby realizing a quick connection between the cross beam 130 and the first longitudinal beam 110 and the second longitudinal beam 120.

[0068] In the above embodiment, the support frame 430 is detachably connected to the scale frame 10. The specific method can be as follows: Figure 2 and Figure 3As shown, a first bottom plate 441 is provided at one end of the bottom surface of the support frame 430, and a second bottom plate 442 is provided at the other end of the bottom surface. Both the first bottom plate 441 and the second bottom plate 442 may be provided with through holes; in addition, a first frame plate 161 is fixedly installed on the side of the first longitudinal beam 110 away from the second longitudinal beam 120. The first frame plate 161 may be a sheet metal part or an angle steel. The top surface of the first frame plate 161 is higher than the top surface of the conveying frame 410. When the conveying frame 410 includes the first bottom beam 41 1 and the second bottom beam 412, the first frame plate 161 is higher than the top surface of the first bottom beam 411, and a second frame plate 162 is fixedly installed on the side of the second longitudinal beam 120 away from the first longitudinal beam 110. The second frame plate 162 can be a sheet metal part or an angle steel. The top surface of the second frame plate 162 is higher than the top surface of the second bottom beam 412, and the first frame plate 161 and the second frame plate 162 are both provided with through holes that match the first bottom plate 441 and the second bottom plate 442. Then, the first frame plate 161 and the first bottom plate 441 are fixedly installed with bolts, and the second frame plate 162 and the second bottom plate 442 are fixedly installed with bolts, so as to realize that the support frame 430 can be detachably connected to the scale frame 10, wherein the upper surfaces of the first frame plate 161 and the second frame plate 162 are flush and higher than the upper surfaces of the first bottom beam 411 and the second bottom beam 412, so as to make the bottom surface of the support frame 430 suspended on the two bottom beams to avoid the first bottom beam 411 and the second bottom beam 412 sharing the gravity of the material, thereby affecting the measurement result.

[0069] Furthermore, the first support beam 20 and the second support beam 30 are both fixedly connected to the conveyor frame 410, and the first support beam 20 and the second support beam 30 are spaced apart along the extension direction of the belt 420. A first detection device is provided on the first support beam 20, and a second detection device is provided on the second support beam 30. The first detection device and the second detection device are both connected to the scale frame 10, and the first detection device and the second detection device are used to detect the pulling force of the scale frame 10.

The first support beam 20 and the second support beam 30 are hollow shell structures with supporting strength. In some embodiments, the first support beam 20 and the second support beam 30 may include a trough body and a cover plate.

The above arrangement can facilitate the maintenance of the first detection device and the second detection device.

[0071] In some embodiments, the first support beam 20 and the second support beam 30 can also be set as a housing of an integral structure, and a mounting hole larger than the first detection device and the second detection device is opened on the side of the housing away from the conveyor frame 410, and a mounting plate 211 larger than the mounting hole is provided. After the first detection device and the second detection device are installed in the first support beam 10 and the second support beam 30 through the mounting hole, the mounting plate 211 is detachably mounted on the mounting hole. The above arrangement can facilitate the maintenance of the detection device, while also ensuring the strength of the first support beam 20 and the second support beam 30.

[0072] Furthermore, a detection device installation hole is opened on one side of the first support beam 20 and the second support beam 30 facing the conveying frame 410 , and the installation hole is used for connecting the detection device with the scale frame 10 .
