Technical Field

[0001] The utility model relates to a feeding crusher. Background Art

[0002] The crusher is used to crush large pieces of material into small pieces for production. The feeding port of traditional crushers all has a door, but the door needs to be held up by one hand when feeding, which poses a safety hazard. In addition, the existing crusher has a poor crushing effect due to the structural reasons of the crushing mechanism. Summary of the invention

[0003] The utility model aims to provide a feeding crusher which can avoid safety accidents and has good crushing effect.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a feeding crusher, including a material box and a crushing mechanism, the material box is provided with a feeding port, the lower part of the material box is provided with a discharge port, the crushing mechanism is arranged above the discharge port, the feeding port is provided with a cylinder-driven door, and the crushing mechanism includes a motor, a main shaft, a plurality of crushing blades and a plurality of support plates, the main shaft is rotatably connected to the material box and driven by the motor, a plurality of crushing blades are fixed on the main shaft, and support plates are provided between adjacent crushing blades, and the crushing blades partially extend into the gap formed by adjacent support plates when rotating.

[0005] Preferably, the upper part of the support plate is a concave arc structure, which is more conducive to material retention and has a good crushing effect.

[0006] Preferably, the crushing blade is a three-edged blade, which is more conducive to crushing.

[0007] Preferably, the feeding surface of the material box is an upward inclined surface, and an inclined feeding port is provided on the inclined surface, so that feeding is more convenient.

[0008] Preferably, the middle of the material box is a funnel-shaped material storage chamber, the lower part is a square crushing chamber, and the discharge port is also funnel-shaped, which is more conducive to material discharge.

[0009] Preferably, the cylinder has two ends located on both sides of the door, one end is hinged to the material box, and the other end is hinged to the door. The cylinder is a suspension cylinder, and after the door is opened, it will be suspended by the cylinder, and both sides of the door are supported.

[0010] After adopting the above structure, the door of the utility model is driven by a cylinder. After the door is opened, the cylinder can suspend the door, which is more convenient for feeding and avoids safety hazards. In addition, a support plate is set between adjacent crushing blades, and a gap is set between the support plates. Large pieces of material are lifted by the support plate and crushed by the crushing blades before falling from the gap between the support plates, which has a good crushing effect.

[0014] The present invention is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0015] See also Figure 1 and 2 As shown, a feeding crusher has a material box 1, and the front of the material box 1 is an upward inclined surface, and an inclined feeding port 3 is arranged on the inclined surface. In order to prevent dust from polluting the working environment during crushing, the feeding port 3 needs to be covered with a door 6, and the door 6 is lifted by a cylinder 5. The cylinder 5 has two ends located on both sides of the door 6, one end of which is hinged to the material box 1, and the other end is hinged to the door 6. Figure 3 As shown, when the door 6 is opened, the two cylinders 5 can make the door 6 suspend, which is convenient for feeding and also avoids the door 6 being closed during feeding, which may cause safety accidents.

[0016] See also Figure 1 and 2 As shown, the middle of the material box 1 is a funnel-shaped material storage chamber 11, the lower part is a square crushing chamber 12, and the lower part of the square crushing chamber 12 is also a funnel-shaped material discharge port 4.

[0017] See also Figure 1 and 2 As shown, the crushing mechanism 2 is the core mechanism of the equipment, and the crushing mechanism 2 includes a motor 21, a main shaft 22, a plurality of crushing blades 23 and a plurality of supporting plates 24. The main shaft 22 penetrates the square crushing cavity 12 of the material box 1 and is rotatably connected to the material box 1 through a bearing seat. The motor 21 drives the main shaft 22 to rotate through a coupling. A plurality of crushing blades 23 are fixed on the main shaft 22. The crushing blades 23 are three-edged blades and are distributed throughout the square crushing cavity 12. Support plates 24 are provided between adjacent crushing blades 23. The two ends of the support plates 24 are fixed on the inner wall of the square crushing cavity 12 and are distributed throughout the square crushing cavity 12. See FIG. Figure 1 As shown, the upper part of the support plate 24 is a concave arc structure, which is more conducive to storing materials, and when the crushing blade 23 rotates, its blade part extends into the gap formed by the adjacent support plates 24.

[0018] When the utility model is used, the door 6 is opened, the door 6 is suspended by the cylinder 5, and the large block material is put into the material box 1 from the feeding port 3, and the material enters the square crushing chamber 12, and is crushed into small pieces by the rotating crushing blades 23 until it can fall from the gap between the supporting plates 24, and the qualified material is discharged from the discharge port 4. The utility model not only avoids the occurrence of safety accidents, but also has a good crushing effect.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
