Description

Technical Field

[0001] This utility model belongs to the technical field of crushing equipment, and specifically relates to a feeding device for a crusher. Background Technology

[0002] During the operation of a crusher, the stability of the feeding process plays a crucial role in its overall performance and processing effect. However, in actual production applications, traditional crushers have many problems in the feeding stage, which seriously affect production efficiency and product quality.

[0003] When dealing with large quantities of materials, especially powders, the drawbacks of traditional crusher feeding methods become particularly apparent. Due to the lack of effective control and guidance mechanisms, a large amount of material rushes into the crusher's inlet in a short period. Without proper flow guidance, this material easily accumulates at the inlet. Over time, the accumulated material gradually forms an arch structure. Once arched, it severely hinders the normal entry of subsequent material, preventing the stable and continuous delivery of material into the crusher.

[0004] This unstable feeding situation has several adverse consequences. From a production efficiency perspective, arching causes material to enter the crusher intermittently, making it impossible for the crusher to maintain a continuous and stable working state. Frequent idling or overloading occurs, significantly reducing the equipment's effective working time and production efficiency. From a product quality perspective, unstable feeding causes uneven stress on the material within the crusher, resulting in some material being over-crushed while others are under-crushed, failing to achieve a uniform crushing effect and severely impacting product quality stability.

[0005] Furthermore, arching can lead to equipment malfunctions, increasing maintenance costs and downtime. Therefore, designing a novel feed mechanism for the crusher is beneficial for improving its production efficiency, product quality, and operational stability. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides a feeding device for a crusher to solve the aforementioned problems.

[0007] This utility model discloses a feeding device for a crusher, comprising a feeding hopper, inside which are arranged two parallel crushing rollers. One end of each crushing roller extends out of the feeding hopper and is respectively provided with meshing gears. The feeding hopper is provided with a drive mechanism for driving the crushing rollers to rotate. The bottom of the feeding hopper is provided with a downwardly inclined feeding pipe, and the feeding pipe is provided with a connecting flange. The bottom of the feeding hopper is provided with several support legs, and the bottom of all the support legs is connected to a base. The base is provided with several adjustable feet.

[0008] Furthermore, a spiral conveying rod is provided inside the feeding pipe, and a driven shaft is installed on the feeding hopper. The driven shaft is connected to the spiral conveying rod through a transmission joint. A first pulley is provided at one end of the crushing roller, and a second pulley is provided at the outer end of the driven shaft. A driving pulley is provided on the output shaft of the drive mechanism. A transmission belt is provided between the driving pulley and the first pulley, and between the first pulley and the second pulley.

[0009] Furthermore, the diameter of the first pulley is smaller than the diameter of the second pulley.

[0010] Furthermore, gear guard plates and transmission belt guard plates are respectively provided on both sides of the feeding hopper.

[0011] Furthermore, the feeding hopper is provided with guide plates located on two symmetrical sides of the crushing roller. The guide plates are detachably connected to the feeding hopper by bolts, and the bottom end of the guide plates extends downward and inward.

[0012] Furthermore, several strong magnetic strips are embedded below the guide plate.

[0013] Furthermore, the end face of the connecting flange is provided with an inner step, and an annular step gasket is embedded in the inner step.

[0018] To better understand this utility model, the embodiments of this utility model will be explained in detail below with reference to the accompanying drawings.

[0019] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0020] This utility model discloses a feeding device for a crusher, comprising a feeding hopper 1, inside which are arranged two parallel crushing rollers 2, which are made of hollow stainless steel. Stainless steel is corrosion-resistant and high-strength, adaptable to the processing needs of different materials, and the hollow structure reduces overall weight while maintaining strength. One end of each crushing roller 2 extends out of the feeding hopper 1 and is equipped with meshing gears 3. Through the meshing of the gears 3, the two crushing rollers 2 can rotate synchronously in opposite directions. A drive mechanism 4 (such as a drive motor) is provided on the feeding hopper 1. This drive mechanism 4 drives either crushing roller 2 to rotate. When the drive mechanism 4 drives one crushing roller 2 to rotate, the other crushing roller 2 will rotate in the opposite direction through the meshing of the gears 3, thereby achieving preliminary crushing of the material in the feeding hopper 1.

[0021] On both sides of the feeding hopper 1, there are gear guard plates 16 and transmission belt guard plates 17 respectively. The gear guard plate 16 can prevent the gear 3 from being disturbed by external debris during operation, and avoid damage to the gear 3 or transmission failure; the transmission belt guard plate 17 can protect the transmission belt 15, prevent it from rubbing against other components or being entangled by foreign objects, and ensure the stability and safety of transmission.

[0022] To further optimize the flow direction of materials within the feeding hopper 1, guide plates 18 are installed inside the feeding hopper 1, located symmetrically on two sides of the crushing rollers 2. The guide plates 18 are detachably connected to the feeding hopper 1 via bolts. This detachable design facilitates replacement or adjustment of the guide plates 18 according to different material characteristics and production requirements. The bottom end of the guide plates 18 extends downwards and inwards, guiding the material to the crushing area between the two crushing rollers 2, allowing the material to make more thorough contact with the crushing rollers 2 and improving the crushing effect. Simultaneously, several segments of strong magnetic strips 19 are embedded below the guide plates 18. These magnetic strips 19 can adsorb any iron impurities that may be present in the material, preventing iron impurities from entering the subsequent pulverizer and damaging the equipment.

[0023] A downward-sloping feeding pipe 5 is installed at the bottom of the feeding hopper 1. The inclined design helps the material slide smoothly down under its own weight. A connecting flange 6 is installed on the feeding pipe 5. The end face of the connecting flange 6 has an inner step, and an annular step gasket 20 is embedded in the inner step. The connecting flange 6 is used to connect the feeding pipe 5 to the subsequent crusher or other equipment. The design of the inner step and the step gasket 20 can enhance the sealing of the connection and prevent material leakage at the connection point.

[0024] A screw conveyor 10 is installed inside the feeding pipe 5. The screw conveyor 10 can further propel the material forward within the feeding pipe 5, ensuring that the material can be stably and continuously conveyed to subsequent equipment. A driven shaft 11 is installed on the feeding hopper 1, and the driven shaft 11 is connected to the screw conveyor 10 through a transmission joint 12. A first pulley 13 is installed at one end of the crushing roller 2, and a second pulley 14 is installed at the outer end of the driven shaft 11. A drive pulley is installed on the output shaft of the drive mechanism 4. Transmission belts 15 are installed between the drive pulley and the first pulley 13, and between the first pulley 13 and the second pulley 14. The diameter of the first pulley 13 is smaller than that of the second pulley 14. This design allows for speed conversion, enabling the screw conveyor 10 to operate at an appropriate speed. This ensures efficient material conveying while preventing material blockage in the feeding pipe 5 due to excessive speed or reduced production efficiency due to insufficient speed.

[0025] The bottom of the feeding hopper 1 is equipped with several support legs 7, and the bottom of all the support legs 7 is connected to a base 8. The base 8 serves to stabilize the entire device, ensuring that the device remains stable during operation. The base 8 is equipped with several adjustable feet 9, which can be adjusted according to the flatness of the actual installation ground to ensure that the device is in a horizontal state and to avoid material flow obstruction or unstable operation of the equipment due to tilting of the device.

[0026] When using the feed device of this crusher, first adjust the device to a level position by adjusting the feet 9 according to the actual installation ground conditions to ensure the stability of the device. Then, connect the feed pipe 5 to the subsequent crusher or other equipment through the connecting flange 6, and check the sealing of the connection to prevent material leakage.

[0027] The usage and principle of this utility model: The drive mechanism 4 is activated, causing one of the crushing rollers 2 to rotate. Through the meshing of gears 3, the other crushing roller 2 rotates in the opposite direction. Simultaneously, through the transmission belt 15 and pulleys, the driven shaft 11 and the screw conveyor 10 are driven to rotate. The material to be processed is poured into the feeding hopper 1. The guide plate 18 guides the material to the crushing area between the two crushing rollers 2, where the crushing rollers 2 perform initial crushing. The crushed material falls into the feeding pipe 5, and under the push of the screw conveyor 10, the material is stably and continuously conveyed along the inclined feeding pipe 5 to subsequent crushers or other equipment. During material conveying, the strong magnetic strip 19 below the guide plate 18 adsorbs iron impurities in the material, preventing them from entering subsequent equipment. Through its reasonable structural design, the entire device achieves stable material feeding, improving production efficiency and product quality.
