Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, specifically relating to a single-tooth roller crusher. Background Technology

[0002] In many industrial sectors such as ore mining, coal processing, and building materials production, material crushing is a crucial pretreatment step. Single-toothed roller crushers, with their unique structure and operating method, offer significant advantages in processing medium-hard and higher hardness materials and are widely used.

[0003] However, existing single-tooth roll crushers have many problems that urgently need to be solved: 1. The tooth material and structural design of traditional toothed rollers are unreasonable. During long-term high-intensity crushing operations, the teeth wear out severely and the replacement frequency is high. This not only increases the equipment maintenance cost, but also leads to a reduction in production efficiency. 2. During operation, some single-tooth roll crushers are prone to problems such as high vibration and high noise due to design defects in the transmission system and frame structure, which affects the service life of the equipment and the working environment. Utility Model Content

[0004] In view of the problems raised in the background art above, the purpose of this utility model is to provide a single-toothed roller crusher.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A single-toothed roller crusher includes a frame, a feed inlet at the top of the frame, a discharge inlet at the bottom of the frame, bearing seats installed on both sides inside the frame, a toothed roller installed between the bearing seats on both sides, a plurality of teeth installed on the surface of the toothed roller, a motor installed on the outside of the frame, a first pulley connected to the power output end of the motor, a belt connected to the first pulley, a second pulley connected to the other side of the belt, and one side of the second pulley connected to one side of the toothed roller.

[0006] Furthermore, the frame is a box-shaped structure, welded from several high-strength steel plates, with internal reinforcing ribs. This structural design enhances the overall strength and stability of the frame.

[0007] Furthermore, the bearing housing is a split bearing housing, and the bearing is a heavy-duty self-aligning roller bearing. This structural design facilitates installation and disassembly, and can withstand large radial and axial loads, ensuring stable operation of the toothed roller.

[0008] Furthermore, the toothed roller is manufactured from a single piece of high-strength alloy steel. This structural design gives the toothed roller excellent strength and toughness, making it more durable.

[0009] Further specified, the teeth are arranged in a trapezoidal structure, with a top width of 15-20 mm and a height of 30-40 mm. The spacing between several teeth is 40-50 mm. The teeth are made of wear-resistant alloy and are fixed to the surface of the toothed roller by welding. This structural design effectively enhances the teeth's gripping and crushing ability, while reducing material slippage on the tooth surface and lowering wear. This further extends the service life of the teeth and the toothed roller.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model enhances the gripping and crushing ability of materials by setting toothed rollers and teeth, reduces the sliding wear of materials on the tooth surface, and greatly improves the wear resistance of the teeth, effectively slowing down the wear rate of the teeth, reducing the replacement frequency, and reducing the cost of spare parts and downtime caused by frequent replacements.

[0011] 2. This utility model effectively improves the overall rigidity and stability of the equipment by combining a box-type reinforced frame with heavy-duty self-aligning roller bearings, reducing the shaking of the transmission system and frame during operation. At the same time, compared with traditional direct drive, belt drive can buffer the power impact between the motor and the toothed roller, further reducing the vibration amplitude during equipment operation. As vibration is reduced, noise is also reduced, improving the workshop working environment and reducing noise interference to operators. Attached Figure Description

Detailed Implementation

[0013] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] like Figure 1-3As shown, this utility model discloses a single-toothed roller crusher. The top of the frame 1 is provided with a feeding port 2, and the bottom of the frame 1 is provided with a discharge port 3. Bearing seats 4 are installed on both sides inside the frame 1, and a toothed roller 5 is installed between the two bearing seats 4. The surface of the toothed roller 5 is provided with a number of teeth 6. A motor 7 is provided on the outside of the frame 1. The power output end of the motor 7 is connected to a first pulley 8. The first pulley 8 is connected to a belt 9. The other side of the belt 9 is connected to a second pulley 10. One side of the second pulley 10 is connected to one side of the toothed roller 5.

[0015] Preferably, the frame 1 has a box-shaped structure, welded from several high-strength steel plates, with internal reinforcing ribs. This structural design enhances the overall strength and stability of the frame 1. However, other structural shapes for the frame 1 can also be considered depending on the specific circumstances.

[0016] Preferably, the bearing housing 4 is a split bearing housing, and its bearing is a heavy-duty self-aligning roller bearing. This structural design facilitates installation and disassembly, and can withstand large radial and axial loads, ensuring the stable operation of the toothed roller 5. In practice, other structural shapes of the bearing housing 4 can also be considered depending on the specific circumstances.

[0017] Preferably, the toothed roller 5 is machined from a single piece of high-strength alloy steel. This structural design gives the toothed roller 5 excellent strength and toughness, making it more durable. In practice, other structural shapes of the toothed roller 5 can also be considered depending on the specific circumstances.

[0018] Preferably, the teeth 6 are arranged in a trapezoidal structure, with a top width of 15-20 mm and a height of 30-40 mm. The spacing between several teeth 6 is 40-50 mm. The teeth 6 are made of wear-resistant alloy and are fixed to the surface of the toothed roller 5 by welding. This structural design effectively enhances the teeth's gripping and crushing ability, while reducing material slippage on the tooth surface and lowering wear. This further extends the service life of the teeth and the toothed roller. In practice, other structural shapes of the teeth 6 can also be considered depending on the specific circumstances.
