[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] like Figures 1 to 4 As shown together, the utility model provides a dual-metering roller speed-regulating belt scale, including a bottom plate 1, a belt scale 2 and a belt scale 3 are respectively installed on both sides of the top of the bottom plate 1, and the height of the belt scale 2 is higher than the height of the belt scale 3, the belt scale 2 and the belt scale 3 are both existing mature technologies, so they are not described in detail, the inlet end of the belt scale 2 is located above the outlet end of the belt scale 3, and a loading bin 5 is installed at the inlet end of the top of the belt scale 2;

[0031] A grid frame 51 is welded inside the upper bin 5. When the coal enters the upper bin 5, the grid frame 51 intercepts and diverts the coal so that the coal passes through the filter screen 59 for filtering more evenly and comprehensively. A filter screen 59 is welded at the outlet end of the upper bin 5. When the coal is poured into the upper bin 5 and falls onto the belt scale 2, it must first be filtered through the filter screen 59 to filter out the large-sized coal and carry it on the filter screen 59. Crushing and squeezing plates 58 are arranged on both sides of the top of the filter screen 59, and the crushing and squeezing plates 58 on both sides are arranged on the top of the filter screen 59. The pressing plate 58 moves toward the middle or both sides at the top of the filter screen 59 at the same time, and the crushing and squeezing plates 58 on both sides move back and forth left and right to squeeze and crush the filtered coal, and after its size is reduced, it falls downward through the filter screen 59, so that the coal meets the feeding requirements after processing, and avoids the coal from accumulating on the top of the filter screen 59 for a long time. Four electric telescopic rods 52 are installed on both sides of the upper bin 5, and the movable end of the electric telescopic rod 52 is located inside the upper bin 5 and connected to one side of the crushing and squeezing plate 58;

[0032] The electric telescopic rods 52 on both sides are extended at the same time, driving the crushing and squeezing plates 58 on both sides to move toward the middle at the same time. Then, the crushing and squeezing plates 58 on both sides push the coal accumulated on the top of the filter 59 to move toward the middle, and the coal will eventually be clamped between the crushing and squeezing plates 58 on both sides. As the electric telescopic rod 52 continues to extend, the crushing and squeezing plates 58 on both sides continue to apply pressure to the coal to squeeze and crush the filtered coal. After crushing, the coal that meets the size continues to fall after being filtered through the filter 59, and the large-sized coal continues to accumulate on the top of the filter 59, waiting for the next squeezing and crushing.

[0033] A flat material component 6 for flattening the belt scale 2 is installed at the top of the belt scale 2 and located on the side of the upper bin 5 close to the belt scale 2 3. A flat material component 7 for flattening the belt scale 2 3 is installed at the top of the belt scale 2 3 and located on the side of the belt scale 2 3 close to the belt scale 2.

[0034] According to a double-metering roller speed-regulating belt scale of an embodiment of the utility model, when coal is loaded, it is first filtered through a filter screen 59, and only coal that meets the size can fall onto the belt of the belt scale 2, which is beneficial to ensure that the size of the coal transported and weighed by the belt scale 2 is uniform, improve the uniformity of the force on the belt scale, and ensure the accuracy of the weighing.

[0035] like Figure 1 As shown, in this embodiment, a guiding receiving bin 4 is installed at the outlet end of the bottom of the belt scale 2, and the outlet end of the guiding receiving bin 4 is located above the inlet end of the belt scale 2 3. The guiding receiving bin 4 ensures that the unloading on the belt scale 2 falls accurately onto the belt scale 2 3.

[0036] like Figures 2 to 3 As shown together, in the present embodiment, a material-blocking cross plate 55 is welded to the top of the crushing and extrusion plate 58, and transverse grooves 56 for the material-blocking cross plate 55 to enter and exit are opened on both sides of the upper bin 5, and retaining bars 54 are welded to the opposite sides of the material-blocking cross plates 55 on both sides. When the crushing and extrusion plates 58 move, the material-blocking cross plates 55 on the top of the crushing and extrusion plates 58 carry the coal entering the upper bin 5, and when the crushing and extrusion plates 58 on both sides move to both sides, the upper bin 5 will push down the material carried on the material-blocking cross plates 55, and filter them through the filter net 59, to ensure that the coal entering the upper bin 5 can be fully filtered through the filter net 59.

[0037] like Figure 3 As shown, in this embodiment, three reinforcing blocks 57 are welded between one side of the crushing and extrusion plate 58 and the bottom of the material blocking cross plate 55, and the reinforcing blocks 57 are triangular in shape. Three vertical slots 53 are opened on both sides of the upper material bin 5, and the reinforcing blocks 57 enter and exit the interior of the upper material bin 5 through the vertical slots 53. The reinforcing blocks 57 play a supporting role for the material blocking cross plate 55.

[0038] like Figures 1 to 4 As shown together, in this embodiment, the structure of the flat material component 1 6 is consistent with that of the flat material component 2 7. The flat material component 1 6 includes a U-shaped frame 61. Two electric telescopic rods 2 62 are installed on the top of the U-shaped frame 61, and the movable ends of the electric telescopic rods 2 62 are located in the inner cavity of the U-shaped frame 61. A flat material plate 64 is installed between the movable ends of the two electric telescopic rods 2 62. The coal falls on the belt scale and the flat material plate 64 flattens the coal on the belt scale. The flat material plate 64 will perform another material leveling operation. The electric telescopic rod 2 62 will drive the flat material plate 64 to rise and fall, and the flattening height of the coal will be adaptively adjusted.

[0039] like Figure 4 As shown, in this embodiment, connecting plates 63 are welded on both sides of the top of the flat plate 64 , and the movable end of the electric telescopic rod 2 62 is connected to the connecting plate 63 .

[0040] like Figure 4 As shown, in the present embodiment, a driving motor 66 is installed near the top on one side of the flat material plate 64, and the driving end of the driving motor 66 is located on the other side of the flat material plate 64. The driving end of the driving motor 66 is fixedly connected to a flat material strip 65, and the driving motor 66 drives the flat material strip 65 to rotate forward and reversely. The flat material strip 65 in a swinging state evenly spreads the coal blocked by the flat material plate 64 to the sides, so that the coal is distributed more evenly on the belt scale, thereby further ensuring the uniformity of the distribution of the coal on the belt scale.

[0041] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
