DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figures 1 to 3 As shown, this embodiment provides a flip material guide trough c, including a bracket 1 and two side plates 2, the two side plates 2 are arranged on opposite sides of the bracket 1 and the two side plates 2 surround a material guide trough body with an upper notch and a lower notch, the two side plates 2 are rotatably arranged on the bracket 1, and the bracket 1 is provided with a flip driving device for driving the two side plates 2 to flip toward the inside of the material guide trough body at the same time.

[0024] When the material transported by the belt conveyor d passes through the flip material guide trough c, the flip driving device will drive the two side plates 2 to flip toward the inner side of the material guide trough body at the same time to avoid the material on the belt conveyor d so that the material can pass through the flip material guide trough c smoothly. Therefore, the flip material guide trough c will not hinder the normal transportation of materials and there will be no material spillage.

[0025] In this embodiment, the opposite sides of the bracket 1 are rotatably provided with turning shafts 3, and the two side panels 2 are respectively fixedly provided on the corresponding turning shafts 3. With such a configuration, the turning of the side panels 2 is achieved.

[0026] In order to support the flip shaft 3 , reduce its friction coefficient during movement, and ensure its rotation accuracy, in this embodiment, a bearing seat 4 is provided on the bracket 1 and the flip shaft 3 is disposed in the bearing of the bearing seat 4 .

[0027] Specifically, the flip shaft 3 is formed by connecting a plurality of alternately arranged solid shafts 31 and hollow shafts 32, wherein the solid shaft 31 is connected between two adjacent hollow shafts 32, and the solid shaft 31 is arranged in the bearing of the bearing seat 4. This structure of the flip shaft 3 saves materials, reduces weight, and reduces production costs.

[0028] In this embodiment, rocker arms 33 are fixedly provided on the two flip shafts 3, respectively, and the flip driving device includes two reciprocating linear motion mechanisms corresponding to the two rocker arms 33, and the two rocker arms 33 are respectively hinged on the corresponding reciprocating linear motion mechanisms. The flip shaft 3 is driven to rotate by the reciprocating linear motion mechanism, which can efficiently generate a large thrust, ensure the smooth flipping of the two side panels 2, and improve the working reliability.

[0029] Since the electro-hydraulic push rod 5 is suitable for places that require reciprocating pushing and pulling movements, as well as for ascending and descending places, it can operate in harsh environments, does not absorb dust or water, is easy to install and maintain, and its pushing and pulling force and operating speed can be steplessly adjusted as needed, has low operating energy consumption and is easy to operate, therefore, the reciprocating linear motion mechanism in this embodiment is preferably the electro-hydraulic push rod 5. Of course, the reciprocating linear motion mechanism can also use a cylinder, an electric cylinder or a hydraulic cylinder, which is selected according to actual needs, and this embodiment does not limit this.

[0030] The side plate 2 in this embodiment includes an upper side plate 21 and a lower side plate 22 set at an angle e. The upper side plates 21 of the two side plates 2 enclose the upper guide section of the guide trough body, and the lower side plates 22 of the two side plates 2 enclose the lower guide section of the guide trough body. The upper guide section and the lower guide section are both conical, and the small end of the upper guide section is connected to the small end of the lower guide section. The large end of the upper guide section is the upper slot end of the guide trough body, and the large end of the lower guide section is the lower slot end of the guide trough body. Such a setting not only guides the falling materials, but also gathers the materials, so that the materials are concentrated in the middle of the belt conveyor, avoiding the materials from being scattered outside.

[0031] In order to better achieve the above technical effects, in this embodiment, the angle e between the upper side plate 21 and the lower side plate 22 is preferably 110°. Of course, the angle e can also be set to other angles according to actual needs, and this embodiment does not limit this.

[0032] In order to improve the connection strength between the upper side plate 21 and the lower side plate 22 , in this embodiment, the upper side plate 21 and the lower side plate 22 are preferably formed in one piece.

[0033] In order to improve the flipping effect, a plurality of push ears 34 are provided between the upper side plate 21 and the hollow shaft 32 in this embodiment.

[0034] In order to improve the sealing effect and further prevent material from being scattered, a sealing rubber plate 6 is provided between the upper side plate 21 and the bracket 1, and an anti-overflow skirt plate 7 is provided on the lower side plate 22. When in use, the anti-overflow skirt plate 7 abuts against the belt of the belt conveyor d.

[0035] In order to increase the service life of the side plate 2 , in this embodiment, wear-resistant lining plates 8 are provided on the inner sides of the upper side plate 21 and the lower side plate 22 .

[0036] In this embodiment, two blocking curtains 9 are further provided on the bracket 1, and the two blocking curtains 9 are respectively provided at the two ends of the material guide trough body; the bracket 1 is also provided with a cover plate 10 for covering the upper notch, and a material inlet connected to the upper notch is provided on the cover plate 10. Such a configuration prevents dust generated by the falling material from overflowing from the two ends of the material guide trough body and the upper notch to spread and pollute the environment.

[0037] When in use, the material is transported by the conveying device a, and falls onto the belt of the belt conveyor d through the unloading barrel b and the overturning material guide trough c. When the material on the belt conveyor d passes through the downstream overturning material guide trough c, the electro-hydraulic push rod 5 will drive the two side plates 2 to overturn toward the inner side of the material guide trough body at the same time to avoid the material on the belt conveyor d so that the material can pass through the overturning material guide trough c smoothly.

[0038] In summary, the flip material guide chute c of the utility model does not hinder the normal transportation of materials and does not cause material spillage.

[0039] The above is only a preferred embodiment of the flip guide trough of the utility model, and there are more embodiments that will not be described in detail here. The utility model is not limited to the above specific implementation methods, and various changes made by ordinary technicians in this field based on the above concept without creative labor are all within the protection scope of the utility model.
