It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model.

[0037] In addition, the terms “first”, “second”, “third”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0038] In addition, the terms "horizontal", "vertical", "overhanging", etc. do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0039] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connection", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0041] It should be understood that during the use of the trough belt conveyor, its tension changes due to its stretching deformation, which may cause the trough shape on the surface of the conveyor belt 400 to change, and the conveyor belt 400 cannot adapt to the trough shape of the roller, which in turn causes the back of the conveyor belt 400 to be unable to fit tightly with the roller, resulting in a low friction coefficient between the roller and the conveyor belt 400, which makes it very easy for the conveyor belt 400 to slip, resulting in problems such as insufficient material spillage or inability to transport.

[0042] In order to improve the above problems, the present embodiment provides a trough belt conveyor, which mainly includes a frame 100, a plurality of horizontal rollers 200, a plurality of inclined rollers 300, a plurality of support rods 500 and a plurality of top plates 600.

[0043] The frame 100 serves as a mounting base for the remaining components of the device and can be arranged according to the size and shape of the remaining components of the device.

[0044] As Figures 1 - 3 shown, a plurality of horizontal rollers 200 are provided on the upper surface of the frame 100, and inclined rollers 300 are respectively provided at both ends of each horizontal roller 200. Among them, each horizontal roller 200 and the inclined rollers 300 at both ends thereof are located in the same plane. The conveyor belt 400 is arranged on the upper surfaces of the plurality of horizontal rollers 200 and inclined rollers 300, and the lower surface of the conveyor belt 400 abuts against the plurality of horizontal rollers 200 and inclined rollers 300. Specifically, the plurality of horizontal rollers 200 are arranged at intervals in sequence along the conveying direction of the conveyor belt 400. The upper surface of the conveyor belt 400 is affected by the horizontal rollers 200 and inclined rollers 300, so that both sides of the upper surface of the conveyor belt 400 are bent relative to the middle area of the upper surface of the conveyor belt 400. In this embodiment, the horizontal rollers 200, inclined rollers 300, conveyor belt 400 and frame 100 are all in the prior art, so no more details will be described here.

[0045] As Figures 1 - 3 shown, a plurality of support rods 500 are respectively arranged on both sides of the inclined roller 300. Specifically, the plurality of support rods 500 are perpendicular to the upper surface of the frame 100, and support rods 500 are respectively provided on both sides of the inclined roller 300. A plurality of top plates 600 are respectively arranged above the plurality of horizontal rollers 200 and are parallel to the upper surface of the frame 100. The support rods 500 on both sides of the same horizontal roller 200 are all supported on the lower surface of the top plate 600 above the horizontal roller 200 and are detachably connected to the top plate 600, so that the top plate 600 is stably arranged above the horizontal roller 200.

[0046] Among them, the top plate 600 is in the shape of a rectangular body, and the four corners of the top plate 600 are respectively detachably connected to the four support rods 500 below.

[0047] As Figures 1 - 3 shown, two pressing members 700 are provided at both ends of the top plate 600. The two pressing members 700 are arranged oppositely, and the two pressing members 700 pass through the top plate 600 and one end abuts against the bent sides of the upper surface of the conveyor belt 400. Specifically, the pressing member 700 includes a connecting rod 710 and a roller pressing member 720. The roller pressing member 720 is arranged on the connecting rod 710. The end of the connecting rod 710 provided with the roller pressing member 720 vertically passes through the top plate 600, and the two roller pressing members 720 located at both ends of the same top plate 600 respectively abut against the two surfaces of the bent part of the upper surface of the conveyor belt 400, so as to press the conveyor belt 400, and further make the lower surface of the conveyor belt 400 respectively abut tightly against the inclined roller 300 and the horizontal roller 200, thereby preventing the conveyor belt 400 from slipping.

[0048] Among them, a plurality of top plates 600 are each provided with a pressing member 700, so as to press the conveyor belt 400 at multiple positions, and further make the conveyor belt 400 closely abut against the horizontal rollers 200 and the inclined rollers 300.

[0049] In this embodiment, as Figure 1 , Figure 3 and Figure 5 shown, the pressing roller member 720 includes a housing 721 and two pressing rollers 722. The housing 721 is connected to one end of the connecting rod 710. The two pressing rollers 722 are respectively arranged on two adjacent surfaces of the housing 721 facing the conveyor belt 400, and the two adjacent surfaces are respectively parallel to two surfaces of the conveyor belt 400 that are bent relatively. Specifically, the two surfaces of the housing 721 that face away from the top plate 600 and are respectively provided with the pressing rollers 722, one surface of the housing 721 is parallel to the horizontal surface of the conveyor belt 400, and the other surface of the housing 721 is parallel to the inclined surface of the conveyor belt 400 that is closest. And the axes of the two pressing rollers 722 are respectively parallel to the two surfaces of the housing 721, so that the outer circumferential walls of the two pressing rollers 722 closely abut against the horizontal surface of the conveyor belt 400 and the inclined surface after bending respectively, and further make the pressing effect of the pressing rollers 722 on the conveyor belt 400 better.

[0050] Among them, the axis of the pressing roller 722 that abuts against the horizontal surface of the conveyor belt 400 is parallel to the axis of the horizontal roller 200, and the axis of the pressing roller 722 that abuts against the inclined surface of the conveyor belt 400 is parallel to the axis of the inclined roller 300 close to the pressing roller 722.

[0051] In some embodiments, as Figures 1 - 4 shown, two threaded blocks 610 and nuts 620 are provided on the upper surface of the top plate 600, and the other ends of the two connecting rods 710 respectively pass through the two threaded blocks 610. Among them, the connecting rod 710 has an external thread, the nut 620 has a first through hole 621 and a second through hole 622, and both the first through hole 621 and the second through hole 622 are provided with internal threads. The first through hole 621 and the second through hole 622 are coaxially arranged, so that the first through hole 621 is threadedly connected to the threaded block 610, and the second through hole 622 is threadedly connected to the other end of the connecting rod 710. Furthermore, the two nuts 620 are respectively threadedly connected to the two threaded blocks 610 and one ends of the two connecting rods 710, so that while fixing the connecting rod 710, it will not rotate the connecting rod 710 due to the reason of threaded connection, and further avoid the direction of the pressing roller 722 from changing after rotating along with the connecting rod 710, so that the conveyor belt 400 cannot be pressed when conveying materials.

[0052] In some embodiments, as Figure 1As shown, the lower surface of the top plate 600 and the top end of the support rod 500 are connected by bolts 900, so that the disassembly and installation between the top plate 600 and the support rod 500 are relatively simple, and thus the maintenance and replacement of the top plate 600 are relatively simple.

[0053] It should be understood that after long-term use of the conveyor belt 400, wear may occur, resulting in a reduction in the thickness of the conveyor belt 400. At this time, the height and angle of the pressure roller 722 need to be adjusted to adapt to the conveyor belt 400.

[0054] Therefore, in order to improve the above problems, as Figure 1 and Figure 5 shown, in some embodiments, the housing 721 has a rotating groove 721a on its upper surface. One end of the connecting rod 710 is arranged in the rotating groove 721a and is rotatably connected to the inner wall of the rotating groove 721a. Specifically, the rotating groove 721a and one end of the connecting rod 710 are connected by a rotating shaft 800. The rotating shaft 800 horizontally passes through one end of the connecting rod 710, and both ends of the rotating shaft 800 are rotatably connected to the inner wall of the rotating groove 721a. Thus, the housing 721 can change the positions of the two pressure rollers 722 by rotation, so that the two pressure rollers 722 always adapt to the upper surface of the conveyor belt 400.
