[0018] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0019] like Figures 1 to 5As shown, a heavy-duty scale plate conveyor described in the utility model includes a support frame 1, a driving sprocket wheel set 2 is arranged on the support frame 1, and the driving sprocket wheel set is connected to the driving assembly, wherein the driving assembly includes a reducer, and the reducer is connected to the driving sprocket wheel set through a coupling, and the reducer is connected to a variable frequency motor through a coupling. When working, the variable frequency motor transmits power to the reducer, and the reducer drives the driving sprocket wheel set to work, and the rotating driving sprocket wheel set drives the driving chain and the scale plate 3 installed on the driving chain to make a circular motion, thereby The feeding operation of the scale plate 3 conveyor is realized; a driving chain is arranged on the driving sprocket wheel group, a scale plate 3 is arranged on the driving chain, a supporting guide wheel 4 is arranged at the bottom end of the scale plate 3, a supporting guide rail 5 is arranged on the supporting frame 1 along its conveying direction, and the supporting guide wheel 4 is slidably located in the supporting guide rail 5; during operation, the sliding of the supporting guide wheel 4 in the supporting guide rail 5 can provide guidance for the movement of the scale plate 3 to avoid the displacement of the scale plate 3 during the conveying process, and can also provide support for the scale plate 3 to reduce the probability of deformation of the scale plate 3 after being subjected to force.

[0020] Furthermore, in the present embodiment, the supporting guide wheels 4 are arranged on the upper and lower sides of the supporting frame 1; wherein the supporting guide rail 5 above the supporting frame 1 is a U-shaped structure, the supporting guide rail 5 under the supporting frame 1 is an inverted U-shaped structure, and support plates 6 are arranged on both sides of the opening of the U-shaped structure. Such an arrangement can ensure that when the upper scale plate 3 runs to the bottom of the supporting frame 1, the supporting plate 6 can be used to provide support and limit the supporting guide wheels 4, thereby realizing the limitation of the scale plate 3 and providing support for the scale plate 3, thereby avoiding the phenomenon of the scale plate 3 sagging due to gravity when running to the bottom, thereby ensuring the stability of the circulating transportation of the scale plate 3.

[0021] Among them, two support rails 5 are arranged along the width direction of the support frame 1, and a transverse reinforcing strut 7 is arranged between the two support rails 5 and the support frame 1 to ensure the bearing capacity of the support rails 5. Two groups of support guide wheels 4 are arranged at the bottom of the scale plate 3, and the two groups of support guide wheels 4 are arranged symmetrically, wherein each group of support guide wheels 4 includes a middle connecting shaft 8, and both sides of the connecting shaft 8 are movably connected with support guide wheels 4, and the top of the connecting shaft 8 is provided with a mounting plate 9, and the mounting plate 9 is installed at the bottom of the scale plate 3 by bolts. Through the arrangement of the two groups of support guide wheels 4, the scale plate 3 can be subjected to balanced force and the supporting effect of the scale plate 3 can be improved. In addition, a supporting wheel group 10 is also arranged at the bottom of the support frame 1, and the supporting wheel group 10 can lift and support both sides of the scale plate 3, and can cooperate with the supporting guide wheel 4 and the supporting rail 5 to avoid the scale plate 3 running to the bottom due to its long length and heavy weight, and reduce the vibration and jumping phenomenon of the scale plate 3 during the transportation process, and at the same time provide guidance for the operation of the scale plate 3.

[0022] Furthermore, protective baffles 11 are provided on both sides of the support frame 1 to limit the running materials and confine the materials within the space enclosed by the protective baffles 11 on both sides. In addition, a hopper 12 is provided at the end of the support frame 1, and the discharge port at the bottom of the hopper 12 is located above the scale plate 3. A guide plate 13 is provided in the hopper 12 to provide a drainage slope for the heavy objects placed in the hopper 12, reduce the height difference between the heavy objects and the scale plate 3, and reduce the impact on the scale plate 3 when pouring the materials. Preferably, as Figure 5 As shown, two guide plates 13 are provided, and the two guide plates 13 are tilted and arranged on both sides symmetrically in the hopper 12; the two guide plates 13 are arranged alternately up and down, and the bottom end of the upper guide plate 13 extends to the top of the lower guide plate 13, with a height difference between them, so as to form a material discharge space; such an arrangement can prevent part of the material from falling directly onto the scale plate 3 without passing through the guide plate 13, ensuring that the falling of the material can be buffered.

[0023] In addition, the guide plate 13 is preferably elastically arranged in the hopper 12. When heavier materials are poured onto the guide plate 13, part of the impact force can be buffered. At the same time, when the guide plate 13 is subjected to force and moves downward due to elasticity, the height difference between the guide plate 13 and the scale plate 3 can be reduced, thereby further reducing the impact force on the scale plate 3. Specifically, the top of the guide plate 13 is hinged to the top of the hopper 12, and guide rods 14 are arranged on both sides of the lower part of the guide plate 13. An arc-shaped guide groove 15 is arranged on the inner wall of the hopper 12. The guide rod 14 slides in the guide groove 15, and a spring 16 connected to the guide rod 14 is arranged in the guide groove 15, so that the guide plate 13 can be quickly reset after being subjected to force. The spring 16 adopts a high-strength spring 16 with a small deformation to ensure its ability to resist external forces; the guide plate 13 is made of high-strength steel plate and has a smooth surface, so that the material can fall smoothly, the structure is simple, and the practicability is strong.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
