[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the embodiments, by Figure 1 and Figure 2 Provided is an anti-backflow device for a material guide trough, comprising an outer frame 1, with a vertical bracket 2, two horizontal brackets 3, two arc-shaped brackets 4 and a connecting frame 5 fixedly connected to the inner side of the outer frame 1. The connecting frame 5 is used to connect the vertical bracket 2 and the horizontal brackets 3 above it. A conveying component 6 for conveying materials is provided on the inner side of the outer frame 1. A plurality of mounting holes 7 are provided on the outer frame 1. An elastic baffle 9 is detachably connected to the inner side of the plurality of mounting holes 7 by bolts 8.

[0019] The transmission assembly 6 comprises two rotating shafts 61, the inner side of the outer frame 1 is rotatably connected with the two rotating shafts 61, the outer side of each of the two rotating shafts 61 is fixedly connected with a belt pulley 62, the two belt pulleys 62 are connected through a belt 63, the belt 63 is in contact with the inner side of the outer frame 1, the outer side of the belt 63 is fixedly connected with a plurality of anti-reverse baffles 64, the end of the anti-reverse baffle 64 is hook-shaped, the front end of the outer frame 1 is fixedly connected with a driving motor 65, the output end of the driving motor 65 extends to the inner side of the outer frame 1, and the output end of the driving motor 65 is fixedly connected to the inner side of the right rotating shaft 61, the vertical bracket 2, the upper horizontal bracket 3 and the upper arc-shaped bracket 4 are used for supporting the upper half of the belt 63, and the lower horizontal bracket 3 and the lower arc-shaped bracket 4 are used for supporting the lower half of the belt 63.

[0020] Through the above setting, the belt 63 is limited by the outer frame 1, the vertical bracket 2, the two horizontal brackets 3, the two arc-shaped brackets 4 and the connecting frame 5, and can only move along the predetermined track. First, the material is poured into the inner side of the outer frame 1 along the elastic baffle 9 and placed on the left upper part of the belt 63. The driving motor 65 is started, the right rotating shaft 61 is driven to rotate through the driving motor 65, and then the belt 63 is driven to move and the left rotating shaft 61 is driven to rotate. During the movement of the belt 63, the anti-reverse baffle 64 is driven to move, the anti-reverse baffle 64 can hold the material, so that the material is driven by the anti-reverse baffle 64 to move to the right first, then move along the arc surface of the belt 63, then move vertically upward, then move along the arc surface of the belt 63, and finally continue to move to the right, completing the transmission of the material. During the transmission of the material, the elastic baffle 9 blocks the material, so the material cannot enter the left lower part of the outer frame 1. During the movement of the anti-reverse baffle 64, although the elastic baffle 9 hinders the anti-reverse baffle 64, the elastic baffle 9 can deform, so it does not hinder the normal passage of the anti-reverse baffle 64. After the normal passage of the anti-reverse baffle 64, the elastic baffle 9 restores the deformation. In addition, since the end of the anti-reverse baffle 64 is hook-shaped, the material is not easy to fall off from the anti-reverse baffle 64 during the transmission.

[0021] Referring to Figure 1 and Figure 2 Wherein two clamping grooves 10 are formed in the outer frame 1.

[0022] Through the above structure, the guide plate can be installed on the inner side of the two clamping grooves 10. After the material is transported by the belt 63 and the anti-reverse baffle 64, it can slide to the target position under the action of inertia.
