[0002] Belt conveyor, also known as rubber belt conveyor, is mainly composed of frame, conveyor belt, belt roller, tensioning device, transmission device, etc. Belt conveyor has the advantages of large conveying capacity, long conveying distance, stable conveying, simple structure, convenient maintenance, low energy consumption, etc. It is widely used in conveying and production lines in mining, metallurgy, wood, casting, building materials and other industries, and also in production departments such as hydropower station construction sites and ports.

[0003] There are various structural forms of belt conveyors, including trough belt conveyors, flat belt conveyors, climbing belt conveyors, tilting belt conveyors, turning belt conveyors, etc. Among them, flat belt conveyors are also called flat belt conveyors. When flat belt conveyors change direction, especially when they change direction downward, they need to use a pressure wheel to control the running position of the belt. However, the pressure wheel usually causes material blockage, seriously affecting production and even causing safety accidents. Summary of the invention

[0004] The purpose of the present invention is to provide a pressure wheel bridge mechanism with a new structure, which is installed at the bending part where the flat belt conveyor turns downward, so as to solve the problem of pressure wheel blocking materials when the flat belt conveyor turns downward without affecting the transportation efficiency of the belt conveyor.

[0008] Optionally, each nylon roller optical axis 10 is fixed to the gear side wall plate 6 and the non-gear side wall plate 7 respectively.

[0009] Optionally, a transition gear 13 is further included, and the gear on the pressing wheel mechanism 3 is meshed with the plurality of roller gears 12 and the transition gear 13 in sequence.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. A person skilled in the art can replace various structural modes with each other and implement the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solutions of the present invention and should not be regarded as the entirety of the present invention or as a limitation or restriction to the technical solutions of the present invention.

[0031] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0032] like Figure 1 As shown, a common flat conveyor is composed of a conveyor frame 1, a conveyor belt 2 and a pressure wheel. The conveyor belt is installed on the conveyor frame. The pressure wheel is fixed at the bend of the drop of the conveyor belt. When the conveyor belt is changed to descend, a bend will be formed at the pressure wheel, and a certain drop will be formed before and after the pressure wheel. The original pressure wheel is now designed into a new pressure wheel mechanism 3, and installed in conjunction with the pressure wheel bridge mechanism 4.

[0033] The pressure wheel bridge mechanism is composed of a slide plate 5, a gear side wall plate 6, a non-gear side wall plate 7, a roller mouth 8, a nylon roller 9, a nylon roller optical axis 10, a nylon roller bearing 11, a roller gear 12, and a transition gear 13.

[0034] like Figure 2 , Figure 3 , Figure 4 As shown, Figure 4It is a schematic diagram of the reverse side of the slide plate of the pressure wheel bridge mechanism. The slide plate 5 is an inclined surface, and its two sides are respectively connected to the gear side wall plate 6 and the non-gear side wall plate 7. An eaves plate 14 extends outward from the top. A plurality of roller openings 8 are provided on the upper surface of the slide plate 5. Each nylon roller optical axis 10 is respectively inserted into the corresponding nylon roller 9. The plurality of nylon roller optical axes correspond to the roller openings 8 respectively. Each roller opening has a nylon roller installed below the roller opening and fixed to the bottom surface of the slide plate 5 through a nylon roller bearing 11. As an optional embodiment, the nylon roller can also be fixed to the gear side wall plate 6 and the non-gear side wall plate 7 instead of the bottom surface of the slide plate 5 (not shown); the outer peripheral surface of each nylon roller 9 is flush with or higher than the upper surface of the slide plate 5, preferably 2-3 mm higher, to ensure that the nylon roller can fully rub the material passing through the slide plate, so that the material slides through the slide plate to the belt surface below when passing through the pressure wheel bridge mechanism, thereby avoiding blockage of the material passing through the pressure wheel. The function of the eaves plate is to prevent the inclination angle of the slide plate from affecting the smooth sliding of the material. The pressure wheel bridge mechanism is fixed above the pressure wheel of the flat belt conveyor, and is fixed to the conveyor frame through the gear side wall plate and the non-gear side wall plate. The power of the pressure wheel bridge mechanism 4 comes from the rotational force formed by the friction of the pressure wheel mechanism 3 when the conveyor belt 2 moves.

[0035] like Figure 5 , Figure 6 , Figure 7 As shown, Figure 6 is with Figure 5 Corresponding to the shaft hole diagram, the gear side wall plate 6 extends outward with a gear side wall plate tongue plate 15, the left side of the slide plate 5 is fixed to the gear side wall plate through the fixing screw hole of the gear side wall plate tongue plate, and one side of the slide plate 5 is welded to the non-gear side wall plate 7. Under the gear side wall plate tongue plate, one end of each nylon roller optical axis 10 is fixed with a roller gear 12.

[0036] The pressure wheel mechanism 3 is fixed on the pressure wheel shaft fixing mechanism 31 and is fixed to the belt pressure wheel. The gears on the pressure wheel mechanism 3 are meshed with multiple roller gears 12 and transition gears 13 in sequence, wherein the gears on the pressure wheel mechanism 3 are directly meshed with the roller gears at the upper and middle positions, and the roller gear at the middle position is meshed with the roller gear at the lower position through the transition gear, and the transition gear plays a reversing role. Multiple roller gears 12 are respectively connected to the nylon roller 9 through the dragon roller optical axis 10. The rotational force generated by the friction pressure wheel of the conveyor belt 2 is transmitted to each roller gear through the gears on the pressure wheel mechanism, driving the nylon roller to rotate. The running direction of the nylon roller 9 is the same as that of the conveyor belt 2; the power of the conveyor belt 2 is finally transmitted to the nylon roller 9 under the slide plate 5 through the gear system of the pressure wheel mechanism 3.

[0037] like Figure 8 , Fig. 9As shown, the pressure roller mechanism 3 is composed of a pressure roller shaft fixing mechanism 31, an optical axis 32, a bearing 33, a bearing sleeve 34, a gear 35, a bearing top tube 36, a cushion block 37, and a pressure roller fixing mechanism 38. The bearing sleeve 34 is sleeved on the bearing 33, the bearing 33 is fixed on the optical axis 32, the gear 35 and the bearing sleeve 34 are connected as a whole, the bearing top tube 36 is covered on the optical axis 32, one end of the optical axis 32 is fixed to the conveyor frame 1 through the gear side wall plate 6 and the pressure roller shaft fixing mechanism 31, and the other end of the optical axis 32 is fixed to the pressure roller fixing mechanism 38 through the non-gear side wall plate 7. At the bottom of the pressure roller bridge mechanism, the pressure roller shaft fixing mechanism 31, the cushion block 37, the gear side wall plate 6, the non-gear side wall plate 7 and the pressure roller fixing mechanism 38 are fixed together with the conveyor frame 1.

[0038] The working principle of the pressure wheel bridge mechanism is to convert the pressure wheel in the prior art into a pressure wheel mechanism by a slide plate "crossing" the pressure wheel, with the upper part being located at the place where the belt starts to descend, and the lower part being located above the belt plane behind the pressure wheel. The slide plate is provided with multiple rectangular roller openings (three are taken as an example in the figure), and the nylon roller is inserted into the optical axis, and a gear is fixed at one end of the optical axis, and the nylon roller inserted into the optical axis is fixed below the roller opening through a bearing. The slide plate fixes the entire bridge pressure wheel mechanism to the frame of the belt conveyor through the wall plates on both sides. The pressure wheel bearing is connected to the gear of the bridge pressure wheel mechanism through the designed bearing sleeve, and the function of the gear is used to transmit the rotational power generated by the movement of the belt to the nylon roller through the meshing of the pressure wheel mechanism gear and the nylon roller gear, so that the nylon roller rotates, and generates rolling friction force on the material sliding over the slide plate of the pressure wheel bridge mechanism, so that the material passes quickly, and the rotational linear speed of the nylon roller is roughly the same as the running speed of the belt, so that the material passing through the pressure wheel mechanism passes quickly, ensuring the smooth belt transportation.

[0039] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
