A coarse crusher

Abstract

This utility model discloses a coarse crusher, belonging to the field of crusher technology. The coarse crusher includes a shredding box and a support frame. A frame cover is provided above the shredding box, and the frame cover is bolted to the shredding box. A shaft frame is provided above the support frame, and the shredding box is bolted to the shaft frame. Hydraulic push rods are provided on both sides of the shaft frame. To address the problem that the internal liner height of existing coarse crushers is mostly fixed and cannot be adjusted in angle, which makes it impossible to adjust the crusher according to the size and type of waste material during the crushing process, easily leading to material stagnation, this invention addresses this issue. For small-volume waste materials, the damping linkage can be rotated to rotate the baffle upwards, thus shortening the depth between the baffle and the shredding blades and preventing waste accumulation. Conversely, for large-volume waste materials, the baffle can be flipped downwards to increase the depth and allow the waste to better contact the blades.

Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a coarse crusher. Background Technology

[0002] Coarse crushers, also known as coarse crushers, are mainly used for the initial crushing of large materials. The materials produced are generally of relatively large particle size. Roller crushers use the friction of the roller surface to bite the material into the crushing zone, so that it is crushed by compression or splitting. When used for coarse crushing or when it is necessary to increase the crushing ratio, teeth or grooves are often made on the roller surface to increase the splitting effect.

[0003] Existing coarse crushers often have fixed internal liner heights that cannot be adjusted in angle. This makes it impossible for the crusher to adjust the crushing process according to the size and type of waste material, which can easily lead to material snagging. Utility Model Content

[0004] The purpose of this utility model is to provide a coarse crusher that, when dealing with small-volume waste materials, can rotate the damping linkage to make the baffle rotate upward, thus shortening the depth between the baffle and the shredding blades and preventing waste accumulation. Conversely, for large-volume waste materials, the baffle can be flipped downward to increase the depth and allow the waste to better contact the blades, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coarse crusher, comprising a shredding box and a support frame, wherein a frame cover is provided above the shredding box, and the frame cover is connected to the shredding box by bolts; a shaft frame is provided above the support frame, and the shredding box is connected to the shaft frame by bolts; hydraulic push rods are provided on both sides of the shaft frame; two sets of shredding blades are provided inside the shredding box; a gate is provided on one side of the frame cover, and hydraulic support arms are provided on both sides of the gate; wherein the gate is rotatably connected to the frame cover.

[0006] Furthermore, a cutting shaft is provided inside the shredding blade, and a locking sleeve is provided between the shredding blades, wherein the shredding blade is connected to the cutting shaft through the locking sleeve.

[0007] Furthermore, a speed reduction assembly is provided at one end of the cutter shaft, and a pulley is provided at the other end of the cutter shaft. A limit plate is provided on the inner side of the speed reduction assembly, and a support shaft is provided at one end of the limit plate.

[0008] Furthermore, the support shaft is rotatably connected to the limiting plate, and the limiting plate is connected to the deceleration assembly through a slot.

[0009] Furthermore, a blade holder is provided below the shredding blade, and the blade holder is connected to the shredding box by bolts. A baffle is provided above the blade holder, and a discharge port is provided below the blade holder.

[0010] Furthermore, a partition liner is provided between the baffles, and both the outer surfaces of the baffles and the partition liner are provided with knife grooves. A damping connecting rod is provided on one side of the baffle, and the baffle is rotatably connected to the shredding box through the damping connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The baffles of this invention are distributed on both sides of the two sets of shredding blades, and the partition liner is located between the two sets of shredding blades. The baffles themselves are inclined to the horizontal shredding blade structure. During the processing, after the waste comes into contact with the baffles, it can bounce back and contact the shredding blades. For some small-volume waste structures, the baffles can be rotated upward by rotating the damping linkage, which can shorten the depth between the baffles and the shredding blades and avoid waste accumulation. Conversely, for large-volume waste, the baffles can be flipped downward to increase the depth so that the waste can contact the blades better. Attached Figure Description

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.

[0019] To address the issue that existing coarse crushers often have fixed-height internal liners that cannot be adjusted in angle, which prevents the crusher from adjusting its operation based on the size and type of waste material and easily leads to material snagging problems; please refer to... Figure 1-4 The present invention provides the following solution:

[0020] Reference Figure 1-2 A coarse crusher includes a shredding box 1 and a support frame 2. A frame cover 101 is provided above the shredding box 1 and is bolted to the shredding box 1. A shaft frame 201 is provided above the support frame 2 and is bolted to the shredding box 1 and the shaft frame 201. Hydraulic push rods 202 are provided on both sides of the shaft frame 201. Two sets of shredding blades 3 are provided inside the shredding box 1. A gate 1011 is provided on one side of the frame cover 101 and hydraulic support arms 1012 are provided on both sides of the gate 1011. The gate 1011 is rotatably connected to the frame cover 101.

[0021] In this embodiment, the hydraulic arm 1012 can flip the gate 1011 outward and then put the waste material into the shredding box 1 from one side of the frame 101. The two sets of shredding blades 3 inside the shredding box 1 rotate under the drive of the motor, and the shredding operation is completed by the shredding blades 3.

[0022] Reference Figure 2-3 The shredding blade 3 has a blade shaft 303 inside, and a locking sleeve 3031 is provided between the shredding blades 3. The shredding blades 3 are connected to the blade shaft 303 through the locking sleeve 3031. A speed reduction assembly 304 is provided at one end of the blade shaft 303, and a pulley is provided at the other end of the blade shaft 303. A limit plate 3021 is provided inside the speed reduction assembly 304. A support shaft 302 is provided at one end of the limit plate 3021. The support shaft 302 is rotatably connected to the limit plate 3021. The limit plate 3021 is connected to the speed reduction assembly 304 through a slot.

[0023] In this embodiment, the limiting piece 3021 can help the deceleration assembly 304 and the cutter shaft 303 reduce vibration and improve stability.

[0024] Reference Figure 2 and Figure 4 Below the shredding blade 3, a blade holder 301 is provided, which is connected to the shredding box 1 by bolts. Above the blade holder 301, a baffle 102 is provided, and below the blade holder 301, a discharge port 103 is provided. A partition liner 1021 is provided between the baffles 102. Both the outer surfaces of the baffles 102 and the partition liner 1021 are provided with blade grooves 1023. A damping connecting rod 1022 is provided on one side of the baffle 102, and the baffle 102 is rotatably connected to the shredding box 1 through the damping connecting rod 1022.

[0025] In this embodiment, baffles 102 are distributed on both sides of the two sets of shredding blades 3, and partition plates 1021 are located between the two sets of shredding blades 3. The baffles 102 and the horizontal shredding blades 3 are inclined. During the processing, after the waste comes into contact with the baffles 102, it can bounce back and contact the shredding blades 3. For some small-volume waste structures, the baffles 102 can be rotated upward by rotating the damping linkage 1022. This can shorten the depth between the baffles 102 and the shredding blades 3 and avoid waste accumulation. Conversely, for large-volume waste, the baffles 102 can be flipped downward to increase the depth so that the waste can contact the blades better.

[0026] Working principle: The hydraulic arm 1012 can flip the gate 1011 outward and unfold it, then the waste material is put into the shredding box 1 from one side of the frame 101. The two sets of shredding blades 3 inside the shredding box 1 rotate under the drive of the motor, and the shredding blades 3 are used to shred the waste material. The baffle 102 is distributed on both sides of the two sets of shredding blades 3, and the partition liner 1021 is between the two sets of shredding blades 3. The baffle 102 itself is inclined to the horizontal shredding blade 3 structure. During the processing, after the waste material comes into contact with the baffle 102, it can rebound to contact the shredding blades 3. For some small-volume waste materials, the damping linkage 1022 can be rotated to make the baffle 102 rotate upward, which can shorten the depth between the baffle 102 and the shredding blades 3 and avoid waste material accumulation. Conversely, for large-volume waste materials, the baffle 102 can be flipped downward to increase the depth so that the waste material can contact the blades better.
