[0035] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0036] Embodiment one, please refer to Figure 1 -Figure 6 The utility model discloses an embodiment of a material falling valve assembly, including valve housing 100, valve housing 100 includes support cylinder 110, and the inside rotation of support cylinder 110 is provided with material falling mechanism 200, and material falling mechanism 200 includes rotation column 210, and the both ends of rotation column 210 are fixed with baffle one 220 and baffle two 230 respectively, and the outside of rotation column 210 is annular and equiangular fixed with a plurality of valve petals 240, and the outside between a plurality of valve petals 240 is provided with cleaning mechanism 300, and the outside of baffle two 230 is rotatably connected with connecting ring 400, and the both sides of support cylinder 110 are provided with telescopic mechanism 500, and telescopic mechanism 500 includes two fixed sleeves 510, and the sliding joint of movable shaft 520 is connected between two fixed sleeves 510, and the end of movable shaft 520, away from fixed sleeve 510, is fixedly connected with corresponding position connecting ring 400.

[0037] Specifically, by setting the plurality of valve petals 240 rotatably installed inside the valve housing 100 into the form that can slide outwards along the valve housing 100, it is convenient to check and maintain the wear condition of the valve petals 240, and it is also convenient to dredge the blocked materials inside the valve housing 100, by arranging the material stirring rods 340 on the outside of the valve petals 240, by pulling the circular ring 310 away from the baffle two 230, the circular ring 310 slides along the surface of the valve petals 240 with the plurality of material stirring rods 340 through the plurality of shafts 320, so that the materials adhered to the outside of the valve petals 240 can be automatically cleaned without disassembling the valve housing 100, which is beneficial to improve the cleaning efficiency of the materials adhered to the outside of the valve petals 240.

[0038] As shown in Figure 2 and Figure 3 , in the embodiment, a circular hole one is formed in the inside of the fixed sleeve 510, and the movable shaft 520 is slidably inserted into the circular hole one, so that the movable shaft 520 can stably slide along the fixed sleeve 510, and it is convenient to pull out the plurality of valve petals 240 from the inside of the valve housing 100.

[0039] As shown in Figure 3 , in the embodiment, a clamping groove is formed in the inside of the circular hole one, and a clamping block 522 is fixedly arranged on the outside of the movable shaft 520 and slidably connected with the clamping groove, wherein the circular hole near the connecting seat 521 is not penetrated through the fixed sleeve 510, so that the movable shaft 520 will not be separated from the fixed sleeve 510 during the sliding process on the fixed sleeve 510.

[0040] As shown in Figure 1 and Figure 3As shown in the drawings, in this embodiment, one end of the movable shaft 520 is provided with two mounting holes, and a bolt is detachably and rotatably connected between the mounting hole and the corresponding position of the fixed sleeve 510. After the valve clack 240 is pushed into the valve housing 100, the bolt can be used to rotatably fix the fixed sleeve 510 near the connecting seat 521 and the movable shaft 520, so as to prevent the valve clack 240 from moving in the valve housing 100.

[0041] As shown in the drawings, Figure 2 , Figure 3 and Figure 5 , in this embodiment, one end of the movable shaft 520 is fixed with a connecting seat 521, and the two connecting seats 521 are fixed on both sides of the connecting ring 400. The outer side of the baffle two 230 is fixed with a rotating ring 231 rotatably connected with the connecting ring 400, so that the movable shaft 520 can drive the connecting ring 400 to move linearly with the rotating ring 231 through the connecting seat 521, and the rotating ring 231 can rotate in the connecting ring 400, so that the rotating column 210 and the baffle two 230 can rotate without interfering with the linear movement of the rotating column 210 as a whole.

[0042] As shown in the drawings, Figure 2 and Figure 4 , in this embodiment, the valve housing 100 further comprises a motor 120 fixed with the supporting cylinder 110. The output end of the motor 120 is fixed with a transmission shaft 121. One end of the rotating column 210 is provided with a transmission groove 211 in transmission plug connection with the transmission shaft 121. After the rotating column 210 and the valve clack 240 are pushed into the valve housing 100, the transmission groove 211 at the end of the rotating column 210 can be sleeved outside the transmission shaft 121 by slightly rotating the rotating column 210, so as to facilitate the transmission shaft 121 to rotate the rotating column 210 through the transmission groove 211.

[0043] In this embodiment, the cross sections of the transmission groove 211 and the transmission shaft 121 are hexagonal, so that the transmission shaft 121 can rotate the rotating column 210 after being inserted into the transmission groove 211.

Multiple shafts 320 are fixed at equal angles on the outside of the ring 310. One end of the shaft 320 is fixedly connected to an arc-shaped rod 330. Both ends of the arc-shaped rod 330 are fixed with a material feeding rod 340 that slides against the valve disc 240.

[0047] Specifically, by pulling the ring 310 outward, the ring 310 moves multiple shafts 320 outward, causing multiple arc-shaped rods 330 and material-pulling rods 340 to move outward. The arc-shaped rods 330 can scrape the material on the outside of the rotating column 210, and the material-pulling rods 340 can scrape the material on the outside of the valve disc 240, thereby achieving automatic cleaning of the material adhering to the material-dropping mechanism 200. In addition, multiple shafts 320 can be pulled back and forth, so that multiple material-pulling rods 340 can move back and forth multiple times on the outside of the valve disc 240, further improving the material cleaning effect.

[0048] like Figure 5 As shown, in this embodiment, multiple circular holes are evenly provided on the outer side of the baffle 230, which are respectively slidably connected to the corresponding shafts 320, so that the multiple shafts 320 can slide stably linearly on the baffle 230.
