Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] like Figure 1 and Figure 2As shown, the embodiment of the utility model provides a support device, which includes: a base 10, a frame 20 and an adjustment mechanism. The frame 20 is arranged on the base 10 and can support the conveyor belt. The adjustment mechanism is arranged between the base 10 and the frame 20, and the adjustment mechanism has a coarse adjustment component and a fine adjustment component arranged in the vertical direction. The coarse adjustment component and the fine adjustment component can both adjust the height of the frame 20, and the adjustment accuracy of the coarse adjustment component is lower than the adjustment accuracy of the fine adjustment component.

[0036] By applying the technical solution of the present invention, the frame 20 is arranged on the base 10 for supporting the conveyor belt, and a coarse adjustment component and a fine adjustment component are arranged between the base 10 and the frame 20 to adjust the height of the frame 20 in the vertical direction, and the adjustment accuracy of the coarse adjustment component is lower than the adjustment accuracy of the fine adjustment component. Such an arrangement can perform multi-stage adjustment of the height of the frame 20 through the adjustment mechanism. When the height of the frame 20 needs to be adjusted, a large-span rough adjustment is first performed through the coarse adjustment component, and then the height of the frame 20 is finely adjusted through the fine adjustment component, so that the frame 20 can adapt to the required height of the conveyor belt under various working conditions, which greatly improves the adjustment accuracy and applicability of the device. At the same time, it can be reused to save costs.

[0037] Specifically, the support device also includes a connector 40, which is arranged between the frame 20 and the base 10. The connector 40 has a first adjustment end and a second adjustment end.

The fine adjustment component is arranged between the second adjustment end and the base 10, and the fine adjustment component adjusts the position of the second adjustment end and the base 10 in the vertical direction. Through the above arrangement, the connector 40 can not only improve the height adjustment range of the frame 20, so that the frame 20 can adapt to the working conditions with higher height adjustment requirements, and further improve the practicality of the frame 20. At the same time, it can also cooperate with the adjustment mechanism to adjust the height of the frame 20, which can save the space volume of the device, greatly improve the rationality of the component layout, and facilitate storage and transportation.

[0038] Among them, the frame 20 is provided with a fixing hole 21, and a plurality of first mounting holes 41 are arranged at intervals along the vertical direction at the first adjustment end. The fixing hole 21 and the first mounting hole 41 form a coarse adjustment component, and the fixing hole 21 cooperates with the first mounting hole 41 through the first fastener 61 to adjust the height of the frame 20 relative to the connecting member 40. Through the above arrangement, the connection between the connecting member 40 and the frame 20 forms a coarse adjustment component, which simplifies the device structure, and through the cooperation between the first mounting hole 41 and the fixing hole 21, the visibility and stability are high during adjustment, and it is possible to always observe whether the height of different first mounting holes 41 is appropriate. After the frame 20 is adjusted to a suitable position, the relative position of the frame 20 and the first adjustment end of the connecting member 40 can be fixed by passing the first fastener 61 through the first mounting hole 41 and the fixing hole 21, and it is convenient to disassemble and assemble, and the operation is very convenient.

[0039] In the present application, a second mounting hole 42 is provided on the second adjustment end, and an adjustment hole 11 is provided on the base 10, the adjustment hole 11 extends in the vertical direction, and the second mounting hole 42 and the adjustment hole 11 form a fine-tuning assembly, and the second mounting hole 42 cooperates with the adjustment hole 11 through a second fastener 62 to adjust the height of the connecting member 40 relative to the base 10. Through the above arrangement, a fine-tuning assembly is formed at the connection between the connecting member 40 and the base 10, which further simplifies the device structure, and through the cooperation between the second mounting hole 42 and the adjustment hole 11, the visibility of the device is further improved.

[0040] After the preliminary height adjustment of the frame 20 is performed through the coarse adjustment component, the relative positions of the base 10 and the second adjustment end of the connecting member 40 can be fixed by passing the second fastener 62 through the second mounting hole 42 and the adjustment hole 11, and the height of the frame 20 can be finely adjusted, thereby improving the adjustment accuracy of the frame 20.

[0041] Specifically, the shape of the adjustment hole 11 is not limited, and can be set to be rectangular, triangular or other shapes, as long as the second mounting hole 42 can be adjusted in the vertical direction within the adjustment hole 11.

[0042] In this embodiment, the adjustment hole 11 is set as a waist-shaped hole, and the waist-shaped hole also extends in the vertical direction, so that it is convenient to adjust the connecting member 40 in the vertical direction. The second fastener 62 is set as an anti-loosening bolt to fix the position of the second mounting hole 42 in the strip hole.

[0043] In this embodiment, the adjustment mechanism is configured to cooperate with the through-hole structure, so that the connecting member can be retracted in the vertical direction for the frame 20 and the base 10, which has a simple structure and is easy to operate. In other embodiments of the present application, the coarse adjustment component and the fine adjustment component can also be configured as a toothed component or a telescopic cylinder.

[0044] Specifically, the support device further includes a guide structure, which is arranged between the frame 20 and the connecting member 40, and between the connecting member 40 and the base 10.

The two vertical beams 23 have a notch on the side away from the horizontal beam 22, and then form a step surface on the side facing the horizontal beam 22. The fixing hole 21 is arranged on the step surface. Such an arrangement is more convenient when assembling the frame 20 and the connecting member 40. At the same time, if the fixing hole 21 is damaged, when the frame slides down, the notch can abut on the first fastener 61 to prevent excessive displacement of the frame 20.

[0051] Among them, a reinforcing rib is provided on the side of the step surface facing the cross beam 22 to ensure the structural strength of the connection with the connecting piece 40.

[0052] In the present application, the first adjustment end of the connector 40 can be made of a square steel tube, and the second adjustment end can be made of a channel steel, both of which are made of stainless steel, do not need to be painted and have better corrosion resistance. A reinforcing plate is provided at the connection between the second adjustment end and the first adjustment end to strengthen the structural strength of the connector 40, thereby improving the stability of the support device.

[0054] In some other embodiments, the first adjustment end and the second adjustment end of the connecting member 40 may also be configured to be adjustable in relative position, which can further enhance the adjustment range and adjustment flexibility of the device.

[0055] Among them, each vertical beam 23 is provided with a support member 50, and two support members 50 are arranged facing each other. The support member 50 is detachably connected to the vertical beam 23 through a third fastener 63, and the support member 50 is used to place the roller. A fixing seat 52 is also provided on the vertical beam 23, and the support member 50 can be fixed on the fixing seat 52 through the third fastener 63. Through the above arrangement, when the support member 50 is worn or broken, it can be replaced at any time, and support members 50 of different sizes can be replaced according to rollers of different sizes, which further improves the practicality of the device.

[0056] In the present application, the support member 50 is provided with a plurality of placement grooves 51 in sequence along the length direction of the conveyor belt to adjust the installation position of the roller. In this way, the position of the roller can be adjusted according to the size of the conveyor belt or different working conditions, thereby improving the flexibility of the support device.

[0057] Specifically, the support device further includes a middle support column 70, which is arranged on the cross beam 22 and cooperates with the support member 50 to support the rollers, and the middle support column 70 is also provided with a groove facing the conveyor belt for placing the rollers. Such a configuration can improve the stability of the placement of the rollers, thereby improving the stability of the support device in supporting the conveyor belt.

[0059] Preferably, the extending direction of the connecting section 12 and the extending direction of the supporting section 13 form an angle of 90°, which can improve the stability of the device.

[0060] The two ends of the support section 13 have bending portions 131, and the bending portions 131 extend toward the frame body 20. With such a configuration, when the support section 13 is fixed on the ground and the support device needs to be disassembled, the support section 13 can be quickly separated from the ground through the bending portions 131.

[0061] Specifically, a connecting seat 231 is further provided on the top of the two vertical beams 23 for connecting with a conveyor.
