Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, specifically a high-power pulverizer. Background Technology

[0002] A crusher is an electric machine that uses mechanical force (such as impact, compression, cutting, etc.) to break large solid raw materials into sizes that meet specific requirements.

[0003] Currently, the crushers used for crushing plastic parts, thin sheets, plates, plastic bottles, etc. use blades for crushing. However, when the blades of existing blade crushers are worn out after a long time, they need to be replaced. This requires removing the blade mounting shaft from the housing to replace the blades. The overall weight of the blade mounting shaft is large, and disassembling the shaft is also tiring and affects the replacement time. Utility Model Content

[0004] The purpose of this invention is to provide a high-power pulverizer to at least partially solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a crushing box, a support frame, and a feeding hopper. The crushing box is fixedly mounted on the support frame, and the feeding hopper is rotatably mounted on the edge of the crushing box. The other edge of the feeding hopper is fixed to the other side of the crushing box by a first bolt. A crushing assembly is provided inside the crushing box. The crushing assembly includes detachably connected blades. A support assembly for supporting the feeding hopper is provided between the folded edge of the feeding hopper and the bottom of the support frame.

[0006] The support assembly includes two guide rods rotatably disposed on the support frame and the edge of the feed hopper, a sleeve slidably disposed between the two guide rods, two pistons fixedly disposed on the inner ends of the two guide rods and sliding on the inner wall of the sleeve, two contact blocks fixedly disposed on the inner ends of the two pistons, and two air holes opened in the middle part of the outer wall of the sleeve.

[0007] Preferably, the pulverizing assembly further includes a pulverizing roller rotatably disposed inside the pulverizing chamber, three blade mounting plates fixedly disposed in a ring on the outer wall of the pulverizing roller, and a plurality of second bolts for fixing the blades.

[0008] Preferably, the feed hopper and the crushing box are respectively fixedly provided with concave seats, one end of the first bolt is rotatably connected in the lower concave seat, and a shaft for supporting the rotation of the first bolt is provided in the lower concave seat, and the other end of the second bolt is fixed in the upper concave seat by a nut.

[0009] Preferably, the crushing box and the rotating part on the other side of the feeding hopper are provided with a connecting shaft, and the feeding hopper and the edge of the support frame are respectively provided with a shaft seat for supporting the rotation of the two guide rods.

[0010] Preferably, the top of the crushing chamber is open, and when the feed hopper is opened, the blades located in the crushing chamber are exposed.

[0011] Preferably, when the feed hopper is perpendicular to the crushing box, the two contact blocks are in contact with each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When this utility model is in use, the connecting shaft set on one side of the crushing box and the feeding hopper allows one side of the feeding hopper to be folded and rotated to the other side of the crushing box, so that the crushing components inside the crushing box are exposed. It is not necessary to remove the entire crushing components from the crushing box, which facilitates the disassembly and replacement of the blades inside the crushing box.

[0014] 2. When the feed hopper is rotated and folded in use, the pistons at one end of the two guide rods that are rotatably connected to one side of the crushing box and the support frame slide on the inner wall of the sleeve and move together. At the same time, the air is slowly vented through the two air holes in the middle of the outer wall of the sleeve, which increases the damping force of the two pistons. This makes the feed hopper move slowly downward when it is lowered. When the folded feed hopper is lowered, it is not necessary to support it by hand. At the same time, it can prevent the feed hopper from contacting and impacting the sleeve, saving the physical strength of the workers and protecting the safety of the workers.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a high-powered crusher, including a crushing box 1, a support frame 2, and a feeding hopper 3. The crushing box 1 is fixedly installed above the support frame 2. The characteristic is that the feeding hopper 3 is rotatably installed on the edge of the crushing box 1, and the other edge of the feeding hopper 3 is fixed to the other side of the crushing box 1 by a first bolt 8. A crushing component 9 is installed inside the crushing box 1. The crushing component 9 includes detachably connected blades 93. A support component 6 for supporting the feeding hopper 3 is installed between the folded edge of the feeding hopper 3 and the bottom of the support frame 2.

[0026] The support assembly 6 includes two guide rods 62 rotatably disposed on the edges of the support frame 2 and the feed hopper 3, a sleeve 61 slidably disposed between the two guide rods 62, two pistons 63 fixedly disposed on the inner ends of the two guide rods 62 and slidably disposed on the inner wall of the sleeve 61, two contact blocks 64 fixedly disposed on the inner ends of the two pistons 63, and two air holes 65 opened in the middle part of the outer wall of the sleeve 61.

[0027] The connecting shaft 4 between the crushing chamber 1 and the feed hopper 3 allows the feed hopper 3 to fold and rotate towards the other side of the crushing chamber 1, exposing the crushing component 9 inside the crushing chamber 1. This eliminates the need to remove the entire crushing component 9 from the crushing chamber 1, facilitating the disassembly and replacement of the blades 93 inside the crushing chamber 1. When the feed hopper 3 folds and rotates, one end of each of the two guide rods 62, which are rotatably connected to one side of the crushing chamber 1 and the support frame 2, moves into the sleeve 61. As one end of the guide rod 62 moves into the sleeve 61, two pistons 63 slide within the sleeve 61. The inner walls of the sleeve 61 are brought together, which increases the air pressure in the sleeve 61. At the same time, the air is slowly vented through the two air holes 65 set in the middle of the outer wall of the sleeve 61, which increases the damping force of the two pistons 63. This causes the two guide rods 62 to slowly move into the sleeve 61. When the contact blocks 64 set on the two pistons 63 respectively come into contact, they can support the vertical feed hopper 3. By slowly setting the feed hopper 3 when it is lowered, it is not necessary to support it by hand when the folded feed hopper 3 is lowered. At the same time, it can prevent the feed hopper 3 from contacting and impacting the sleeve 61, saving the workers' physical strength and protecting the safety during work.

[0028] More preferably, the crushing assembly 9 also includes a crushing roller 91 rotatably disposed inside the crushing box 1, three blade mounting plates 92 fixedly disposed in a ring on the outer wall of the crushing roller 91, and a plurality of second bolts 94 for fixing the blades 93.

[0029] The crushing roller 91 is set inside the crushing box 1 and rotates. It is driven by the belt pulley of the crusher body. Three blade mounting plates 92 are arranged in a ring on the outer wall of the crushing roller 91 for mounting blades 93, which can crush the materials inside the crushing box 1.

[0030] More preferably, the feed hopper 3 and the crushing box 1 are respectively fixedly provided with concave seats 7 on one side, one end of the first bolt 8 is rotatably connected in the lower concave seat 7, and a shaft for supporting the rotation of the first bolt 8 is provided in the lower concave seat 7. The other end of the second bolt 94 is fixed in the upper concave seat 7 by a nut.

[0031] The concave seats 7 are respectively set on one side of the feed hopper 3 and the crushing box 1. One end of the first bolt 8 is rotatably set on the lower concave seat 7, and the other end of the first bolt 8 is located on the upper concave seat 7. The two concave seats 7 are constrained and fixed by the first bolt 8 on the upper concave seat 7, and the foldable and rotatable feed hopper 3 and crushing box 1 are constrained and fixed.

[0032] More preferably, a connecting shaft 4 is provided on the rotating part of the crushing box 1 and the feeding hopper 3 on the other side, and a shaft seat 5 for supporting the rotation of the two guide rods 62 is provided on the edge of the feeding hopper 3 and the support frame 2 respectively;

[0033] A connecting shaft 4 is provided on the other side of the crushing box 1 and the feeding hopper 3, and the rotating end of the connecting shaft 4 is connected to the feeding hopper 3. It is used to support the feeding hopper 3 to rotate on one side of the crushing box 1. A rotating shaft seat 5 is provided on the crushing box 1 and the support frame 2 to support one end of each of the two guide rods 62 to rotate on the crushing box 1 and the support frame 2 respectively.

[0034] More preferably, the top of the crushing box 1 is open, and when the feed hopper 3 is opened, the blades 93 located in the crushing box 1 are exposed;

[0035] With the top of the crushing box 1 open, the blades 93 on the crushing assembly 9 inside the crushing box 1 are exposed after the feed hopper 3 is opened, allowing for maintenance and replacement of the blades 93 inside the crushing box 1.

[0036] More preferably, when the feed hopper 3 is perpendicular to the crushing box 1, the two contact blocks 64 are in contact with each other;

[0037] By using contact blocks 64 on the two pistons 63, a gap is maintained between the two pistons 63, while preventing them from colliding.

[0038] One specific application of this embodiment is as follows: when the maintenance blade 93 needs to be replaced, the first bolt 8 is loosened, so that one end of the first bolt 8 is removed from the upper concave seat 7 and is no longer constrained and fixed to one side of the crushing box 1. Through the connecting shaft 4 set on one side of the crushing box 1 and the feed hopper 3, one side of the feed hopper 3 can be folded and rotated to the other side of the crushing box 1, so that the crushing component 9 inside the crushing box 1 is exposed. It is not necessary to remove the entire crushing component 9 from the crushing box 1, which makes it convenient to disassemble and replace the blade 93 inside the crushing box 1.
