DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0028] In order to solve the technical problems in the background technology, the following anti-blocking net for the feeding port of the grinding belt is provided:

[0029] Combination Figure 1-Figure 8 As shown, the anti-blocking net for the feeding port of the grinding belt provided by the utility model comprises a chute 1, a feeding port 11 is arranged at the top of the chute 1, a roller mill 7 is arranged at the bottom of the chute 1, a first mounting port 12 is arranged at the side of the bottom of the chute 1, a second mounting port 13 is arranged at the other side of the bottom of the chute 1, a first mounting component 2 is arranged inside the first mounting port 12, a second mounting component 3 is arranged inside the second mounting port 13, an interception rod 4 for intercepting foreign matter of materials is arranged between the first mounting component 2 and the second mounting component 3, and a dredging mechanism 5 for dredging materials is arranged inside the chute 1;

[0030] The first mounting assembly 2 comprises a first mounting bar 21 and a first mounting plate 22. The first mounting bar 21 is provided with a first mounting plate 22 on the top and bottom surfaces. The first mounting bar 21 and the first mounting plate 22 are both engaged with the first mounting opening 12. A plurality of intercepting rods 4 are provided at equal intervals on the side of the first mounting bar 21. The plurality of intercepting rods 4 form an intercepting net. The intercepting net formed by the intercepting rods 4 can intercept the material entering from the discharge opening 11 and intercept the material that is larger than the interval of the intercepting rods 4. The first mounting plate 22, the first mounting bar 21 and the first mounting opening 12 are engaged with each other, so that the first mounting assembly 2 can fix the intercepting rod 4 inside the chute 1.

[0031] In this embodiment, the second mounting assembly 3 includes a second mounting bar 31 and a second mounting plate 32. The second mounting bar 31 has a second mounting plate 32 on its top and bottom surfaces. The second mounting bar 31 and the second mounting plate 32 are both engaged with the second mounting opening 13. A mounting hole is provided in the middle of the second mounting bar 31, and the mounting hole engages and slides with the intercepting rod 4. The mounting hole provided in the middle of the second mounting bar 31 facilitates engagement and fixation with the end of the intercepting rod 4 away from the first mounting assembly 2. The first mounting assembly 2 and the second mounting assembly 3 fix the intercepting rod 4, so that the staff can dismantle and replace the intercepting rod 4 after the anti-blocking net has been used for a long time, so as to facilitate the staff to replace the second mounting assembly 3 with intercepting rods 4 with different spacings.

[0032] In this embodiment, an observation window 15 is provided on the bottom side of the chute 1, and the observation window 15 is located above the interception net; the observation window 15 provided on the side of the chute 1 facilitates the staff to observe the material discharge state inside the chute 1 to avoid material accumulation;

[0033] When the anti-blocking net is in use, the grinding belt delivers the material to be roller-milled into the chute 1 from the discharge port 11. At this time, the interception net formed by the multiple interception bars 4 can screen the material and separate the larger debris in the material. Then, the dredging mechanism 5 cooperates with the interception net to continuously push the larger material so that the larger material is dispersed and passes through the interception net.

[0034] The interception net formed by the interception rod 4 inside the chute 1 can screen the material entering the chute 1, so that the material blocks, chute 1 crust and other debris are left above the interception net, which can prevent larger debris from entering the roller mill 7 and causing malfunctions such as blockage of the roller mill 7, thereby facilitating the stable operation of the roller mill 7. Example 2

[0035] like Figure 1-Figure 8 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0036] In order to prevent the material from piling up above the interception net, the present embodiment provides the following design:

[0037] The middle part of the slide pipe 1 is provided with a movable opening 14, and the dredging mechanism 5 includes a dredging plate 51, a movable rod 52, a support rod 53 and a reciprocating electric push rod 54. The support rod 53 is arranged inside the movable opening 14, and the support rod 53 is engaged and slidably engaged with the movable opening 14. A reciprocating electric push rod 54 is arranged at one end of the support rod 53, and the reciprocating electric push rod 54 is located on the outside of the slide pipe 1. A movable rod 52 is arranged at the other end of the support rod 53, and a dredging plate 51 is arranged on the other side of the movable rod 52 at equal intervals; the reciprocating electric push rod 54 arranged on the outside of the slide pipe 1 can control the movable rod 52 and the dredging plate 51 to reciprocate inside the slide pipe 1 through the support rod 53; the dredging plate 51 reciprocating inside the slide pipe 1 can continuously strike the material blocks above the interception net, the crust of the slide pipe 1 and other debris, and then can break up the debris on the interception net, so that the debris passes through the interception net after being dispersed, so that the interception net is not easily blocked by foreign matter accumulation;

[0038] In this embodiment, the interception net and the dredging plate 51 are arranged at an angle on the inner side of the slide pipe 1; the interception net and the dredging plate 51 are arranged at an angle, so that the reciprocating dredging plate 51 can collide and disperse the foreign matter on the interception net;

[0039] In this embodiment, a partition bar 6 is provided inside the slide pipe 1, and the partition bar 6 is provided corresponding to the dredging plate 51, and the dredging plate 51 is an inverted trapezoidal structure; the partition bar 6 provided inside the slide pipe 1 can cooperate with the dredging plate 51 to disperse foreign matter.

[0040] The working principle and use process of this utility model:

[0041] When using:

[0042] When the anti-blocking net is in use, the grinding belt delivers the material to be roller-milled from the discharge port 11 into the chute 1. At this time, the interception net formed by the multiple interception bars 4 can screen the material and separate the larger debris in the material. Then, the dredging mechanism 5 cooperates with the interception net to continuously push the larger material so that the larger material is dispersed and passes through the interception net. In this way, the interception net can separate the larger material blocks, crusts in the chute 1 and other debris in the material, thereby preventing the larger debris from entering the roller mill 7 and affecting the normal operation of the roller mill 7.

[0043] During use:

[0044] The reciprocating electric push rod 54 in the dredging mechanism 5 drives the support rod 53 to move. When the support rod 53 moves, it will drive the movable rod 52 and the dredging plate 51 to reciprocate inside the chute 1. At this time, the dredging plate 51 cooperates with the dividing strip 6 to continuously strike the material blocks above the interception net, the crust of the chute 1 and other debris, so that the debris on the interception net is dispersed into a size that can pass through the interception net. In this way, the debris intercepted above the interception net can be dredged without affecting the operation of the roller mill 7, so that the foreign matter on the interception net is not easy to accumulate and clog, thereby facilitating the long-term use of the anti-blocking net.
