As shown in fig. 1 and 2, the crusher with adjustable feeding port comprises a crushing box body 100, the crushing box body 100 encloses a crushing cavity 110, a feeding port 120 is arranged on the crushing box body 100, and the feeding port 120 is communicated with the crushing cavity 110. The crushing box body 100 is further provided with a flaring adjusting plate 130, the flaring adjusting plate 130 is provided with a pivoting connecting end 131 and a material stopping end 132, the pivoting connecting end 131 is pivotally connected with the crushing box body 100, and the material stopping end 132 and the crushing box body 100 jointly enclose a feeding hole 120. The flared adjustment plate 130 rotates about the pivot connection end 131 when the tail end 132 is compressed by material to expand the feed inlet 120.

According to the utility model, the flaring regulating plate 130 is arranged on the crushing box body 100, so that the crushing box body 100 and the flaring regulating plate 130 enclose the feeding hole 120 together, the feeding hole 120 is communicated with the crushing cavity 110 in the crushing box body 100, and materials can directly enter the crushing cavity 110 through the feeding hole 120 to be crushed. When the material is dumped into the feed inlet 120, the material with larger size contacts with the material blocking end 132 of the flaring adjusting plate 130 and extrudes the material blocking end 132, at the moment, the flaring adjusting plate 130 starts to rotate around the pivot connection end 131 due to stress, so that the size of the feed inlet 120 surrounded by the crushing box body 100 and the flaring adjusting plate 130 is increased, the material with larger size can also enter the crushing box body 100 through the feed inlet 120, after the material enters the crushing box body 100, because the flaring adjusting plate 130 is not stressed any more, the flaring adjusting plate 130 is restored to the original position under the action of self gravity, and the feed inlet 120 is reduced. In the whole process, operators do not need to participate, the crusher can realize the self-adjustment of the feeding hole 120, and the automation degree and the working efficiency of the crusher are improved.

More specifically, the crushing box 100 is provided with a limiting protrusion 150 at a pivot joint 131 with the flaring regulating plate 130, and the limiting protrusion 150 abuts against the flaring regulating plate 130 which is not in an expanded state, so that the flaring regulating plate 130 is prevented from shielding the feed port 120. The limiting protrusion 150 limits the initial position of the flare adjusting plate 130, and avoids the phenomenon that the flare adjusting plate 130 blocks the feed port 120 due to the sagging of the flare adjusting plate 130 under the action of self gravity. It will be appreciated by those skilled in the art that the position-limiting protrusion 150 may take any of a variety of possible embodiments other than the structure adopted by the present invention, such as a position-limiting chute, a position-limiting baffle, etc.

More specifically, the stopping end 132 of the flared adjustment plate 130 has a raised angle structure 136, the raised angle structure 136 is raised in a direction away from the feed inlet 120, and the raised angle structure 136 guides and presses the material into the feed inlet 120. The rake structure 136 is raised to the direction of keeping away from feed inlet 120, has increased the entry size of feed inlet 120, when the material gets into feed inlet 120, can be guided by rake structure 136 and slide in broken box 100, avoids appearing the material card and takes place in the condition of feed inlet 120. In addition, the contact area of material end 132 and material can be increased to rake structure 136 for material end 132 extrudes the material of card at feed inlet 120 through rake structure 136, and then makes the material get into crushing box 100.

More specifically, a multi-layer curtain 133 is further installed on the flared adjustment plate 130, and the curtain 133 hangs down from the flared adjustment plate 130 to shield the feed inlet 120. When the material is broken in broken box 100, can cause a large amount of garrulous phenomena that collapse, if the piece is collapsed outside broken box 100, can cause the threat to operating personnel's personal safety, consequently, installation shielding curtain 133 on flaring regulating plate 130 for shielding curtain 133 shields feed inlet 120, makes shielding curtain 133 can block the piece departure broken box 100.

More specifically, the curtain 133 includes a metal chain curtain 135 and at least one layer of rubber curtain 134, and the rubber curtain 134 is disposed outside the metal chain curtain 135. Metal chain curtain 135 self has great gravity, sets up and to block the piece that has great kinetic energy in the inboard of rubber curtain 134, and rubber curtain 134 can block the less piece of size that passes metal chain curtain 135, and in addition, rubber curtain 134 still has certain dustproof function, blocks the dust in broken box 100 and outwards spreads.

More specifically, the two adjacent rubber shielding curtains 134 are arranged in a staggered manner, so that the two adjacent rubber shielding curtains 134 can be stacked, and the capability of the rubber shielding curtains 134 for blocking fragments is increased.

More specifically, the crushing box 100 is provided with a pressure plate 160 at the pivotal connection with the flare adjusting plate 130, the pressure plate 160 includes a fixed end 161 fixedly connected with the crushing box 100 and a force applying end 162 abutting against the flare adjusting plate 130, and the pressure plate 160 provides pressure to the flare adjusting plate 130 so that it is not frequently lifted. The fixed end 161 of the pressure plate 160 is fixed with the crushing box 100, and the forcing end 162 abuts against the flaring regulating plate 130, so that the pressure plate 160 can provide certain pressure for the flaring regulating plate 130, when the material blocking end 132 of the flaring regulating plate 130 is subjected to smaller material pressure, the pressure provided by the pressure plate 160 can be offset, so that the material can be extruded by the corner structure 136 of the material blocking end 132 to enter the material inlet 120, and the flaring regulating plate 130 is prevented from being frequently lifted.

More specifically, the pressure plate 160 is a hard rubber plate, and the pressure plate 160 can provide sufficient pressure to the flare adjusting plate 130, and in addition, the hard rubber plate has certain elasticity and can automatically recover after being bent by the flare adjusting plate 130.

More specifically, the crushing box 100 further includes a counterattack plate 140 and a rotary hammer body 170, the counterattack plate 140 is fixedly disposed on an inner wall of the crushing box 100, the rotary hammer body 170 is rotatably connected to the crushing box 100, the counterattack plate 140 is disposed around a circumference of the rotary hammer body 170, the counterattack plate 140 includes a first counterattack plate 141 and a second counterattack plate 142, and an interval between the second counterattack plate 142 and the rotary hammer body 170 is smaller than an interval between the first counterattack plate 141 and the rotary hammer body 170. The rotary hammer body 170 rotates in the crushing box body 100, so that the materials and the impact plates 140 are extruded and crushed, the interval between the first impact plate 141 and the rotary hammer body 170 is large, the materials with large size can be crushed conveniently, and the crushed materials and the materials with small size enter the space between the second impact plate 142 and the rotary hammer body 170 to be further crushed until the materials with qualified size are obtained.

So far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without departing from the technical principle of the present invention, a person skilled in the art may split and combine the technical solutions in the above embodiments, and may make equivalent changes or substitutions for related technical features, and any changes, equivalents, improvements, etc. made within the technical concept and/or technical principle of the present invention will fall within the protection scope of the present invention.
