[0031] The belt conveyor is a common bulk material conveying device that uses a belt to carry materials and conveys them along the erection direction of the idlers. The idlers have a structure with both sides upturned to concentrate the materials in the middle area for conveyance and prevent the materials from spreading from both sides. However, at the elevation conveying position of the belt conveyor, the belt will be stressed and straightened, causing the materials to spread to both sides. Therefore, referring to Figure 5 and Figure 6 , two pressure rollers 500 are arranged above the belt to increase the friction force and limit the belt to prevent the belt from being straightened to both sides. In the conveyance of large particle materials, the traditional pressure rollers will limit the material conveyance and there is interference.

[0032] Therefore, the present utility model provides a conveying mechanism that can avoid interfering with the materials.

[0033] Referring to Figures 1 to 6 , a conveying mechanism according to an embodiment of the present utility model includes an idler assembly 300, a mounting frame 100, a heightening seat 400, and a pressure roller 500. A plurality of idler assemblies 300 are provided for installing and supporting the conveying belt. The mounting frame 100 is erected above the idler assembly 300. The mounting frame 100 is provided with a mounting portion 102 that is arranged to be lifted and lowered. The mounting portion 102 is located above the conveying belt, and the distance to the conveying belt is changed by lifting and adjusting. Combining with the figure, in this embodiment, the width direction of the conveying belt is the left-right direction. Therefore, the mounting portion 102 spans left and right. Two heightening seats 400 are provided, and the two heightening seats 400 are arranged at the lower end of the mounting portion 102 in a left-right adjustable manner. A pressure roller 500 is rotatably arranged on each heightening seat 400, so as to press both sides of the conveying belt through the two pressure rollers 500 and inhibit the conveying belt from being straightened to both sides. The rotation center of the pressure roller 500 is horizontally arranged.

[0034] It can be understood that in the conveying mechanism of the present utility model, the mounting frame 100 is used to mount the pressure belt wheel 500 above the conveying belt, so as to realize the pressing connection of the pressure belt wheel 500 to the conveying belt. On this basis, by setting a heightening seat 400 at the lower end of the mounting part 102 to mount the pressure belt wheel 500, a sufficient vertical distance can be maintained between the pressure belt wheel 500 and the mounting part 102, thereby avoiding the interference between the materials accumulated on the conveying belt and the mounting part 102, and effectively solving the deficiencies of the traditional structure.

[0035] Referring to Figure 1 , in some embodiments of the present utility model, the mounting frame 100 includes two brackets 101, and the brackets 101 are vertically erected on both sides of the idler assembly 300 and extend upward to a height higher than the conveying belt. The mounting part 102 is installed between the two brackets 101 so as to be mounted above the conveying belt.

[0036] Among them, referring to Figure 3 , the bracket 101 is vertically provided with two I-beams 1011, and a certain distance is maintained between the two I-beams 1011, and the webs are kept opposite front and back, thereby forming a lifting cavity 1012 with openings on both left and right sides. The two ends of the mounting part 102 are slidably arranged in the two lifting cavities 1012 formed by the two brackets 101. With the structural setting of this embodiment, the I-beams 1011 can ensure the structural strength, and at the same time, the lifting cavity 1012 is formed by the I-beams 1011, which is convenient for intuitively judging the installation situation of the mounting part 102. Since the conveyed material is bulk material, it can effectively avoid the problem that the material enters it and makes it difficult to adjust the lifting of the mounting part 102.

[0037] In some embodiments of the present utility model, rubber wheels that abut against the webs of the I-beams 1011 are provided on the front and rear sides of the two ends of the mounting part 102, and the width direction is directly limited by the way of plate-to-plate fitting. In this way, the rubber wheels can be used to achieve shock absorption in the front and rear directions and improve the stability of the structure.

[0038] Referring to Figure 1 and Figure 2 , a screw rod lifting adjustment assembly 200 for connecting the mounting part 102 is provided at the upper end of the bracket 101. Specifically, the screw rod lifting adjustment assembly 200 includes an adjustment screw rod 201 passing through the bracket 101, and the lower end of the adjustment screw rod 201 is threadedly connected to the mounting part 102, so as to drive the mounting part 102 to move up and down for adjustment when rotating.

[0039] Referring to Figure 1, in some embodiments of the present utility model, the heightening seat 400 includes two supports 401 arranged at intervals left and right. The pressure belt wheel 500 is rotatably arranged between the two supports 401, so as to ensure the structural stability and support strength of the pressure belt wheel 500. On one side of each support 401 facing away from the pressure belt wheel 500, rib plates are arranged in the left-right direction for structural strengthening.

[0040] To facilitate the installation of the heightening seat 400, the installation part 102 adopts a beam structure. The upper end of the heightening seat 400 is installed on the installation part 102 through bolts, and by arranging a plurality of installation holes along the length direction of the installation part 102, the heightening seat 400 can be installed at different positions on the installation part 102 to realize left-right movement adjustment.

[0041] Considering the situation where materials enter below the pressure belt wheel 500, which is likely to cause damage to the equipment. Therefore, referring to Figure 4 , in some embodiments of the present utility model, an installation opening 4011 is provided on the support 401. A mounting shaft 501 is provided at the center of the pressure belt wheel 500. Bearing seats 502 are arranged at the left and right ends of the mounting shaft 501. The bearing seats 502 are installed in the installation opening 4011, and a spring 4012 is arranged between the circumferential direction of the bearing seat 502 and the installation opening 4011. With the structural arrangement of this embodiment, the bearing seat 502 can deflect 360° up, down, left and right through the circumferential spring 4012. Combining the yaw of the two bearing seats 502 on both sides, the pressure belt wheel 500 can move up, down, forward and backward and deflect. With the structural arrangement of this embodiment, when materials are pressed below the pressure belt wheel 500, the pressure belt wheel 500 can avoid interference through yaw displacement, which is beneficial to extending the service life of the equipment.

[0042] In some embodiments of the present utility model, a rubber ring is arranged on the outer peripheral side of the pressure belt wheel 500, and the outer peripheral surface of the rubber ring is a conical surface. Using the conical surface to press the conveyor belt is beneficial to increasing the contact area between the pressure belt wheel 500 and the conveyor belt and improving the pressing effect. It can be understood that the taper direction of the conical surface is consistent with the inclination direction of the conveyor belt it abuts against.

[0043] In some embodiments of the present utility model, a limiting rib is protrudingly provided on the rubber ring on the conical surface. The limiting rib is spirally distributed around the axis of the pressure belt pulley 500, and along the rotation direction of the pressure belt pulley 500, the front end of the limiting rib is located at the small end of the conical surface, and the rear end of the limiting rib is located at the large end of the conical surface. During the transmission of the conveyor belt, the pressure belt pulley 500 will rotate accordingly under the action of friction. Since the limiting rib is made of rubber structure, it is beneficial to increase the acting force between the pressure belt pulley 500 and the conveyor belt. At the same time, the spiral direction of the limiting rib makes the contact position between the limiting rib and the conveyor belt move from the outside to the inside, and the limiting rib will form a centripetal acting force on the conveyor belt, so as to apply a centripetal acting force on the basis of pressing to inhibit the conveyor belt from being straightened.

[0044] Furthermore, in some embodiments of the present utility model, the idler assembly 300 includes a horizontal idler 301 and inclined idlers 302 provided at both ends of the horizontal idler 301. The inclined idlers 302 on both sides are upturned at the ends, so as to limit the conveyor belt into a form with both sides upturned. Convex ribs are provided on the surface of the inclined idler 302. The convex ribs are spirally distributed around the axis of the inclined idler 302, and along the rotation direction of the inclined idler 302, the front end of the convex rib is farther away from the horizontal idler 301 than the rear end of the convex rib. It can be understood that during the rotation of the inclined idler 302 in this embodiment, a centripetal acting force can also be applied to the conveyor belt through the convex ribs to inhibit the conveyor belt from being straightened to both sides.

[0045] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present utility model pertains, various changes can be made without departing from the gist of the present utility model. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
