Description

Technical Field

[0001] This utility model relates to a crushing device, specifically a basalt coarse aggregate particle crushing device, belonging to the technical field of mining machinery and building material processing equipment. Background Technology

[0002] In mining, building materials production, and other fields, basalt coarse aggregate often needs to be crushed to obtain particles that meet specific size requirements for use in road paving, concrete preparation, and other projects. Currently, there are many types of crushing equipment on the market, but they still have many shortcomings in crushing basalt coarse aggregate. Common crushing equipment includes jaw crushers, impact crushers, and vertical shaft impact crushers. Among them, vertical shaft impact crushers are widely used due to their high-efficiency crushing capacity, but they still have the following problems:

[0003] The existing shaft impact crusher transmission system uses a motor drive method. The motor is usually directly fixed to one or both ends of the crusher body. When the vertical shaft impact crusher is crushing basalt coarse aggregate particles, due to the hard texture of basalt, a large impact force and vibration will be generated during the crushing process. When the motor is subjected to such continuous and strong vibration, the traditional motor installation method may not be able to effectively fix the motor, causing the motor to shift or shake during operation, affecting the normal operation of crushing, and even causing failures such as pulley misalignment and belt slippage, reducing crushing efficiency and quality.

[0004] Furthermore, existing crushing equipment has shortcomings in terms of heat dissipation and dust prevention in the transmission system. The transmission system generates a large amount of heat during operation; if this heat is not dissipated in time, it will cause the motor and transmission components to overheat, reducing the equipment's lifespan. Moreover, the crushing of basalt generates a large amount of dust, which can enter the motor transmission chamber, affecting the normal operation of the transmission components and even causing equipment failure. Utility Model Content

[0005] The purpose of this invention is to provide a basalt coarse aggregate particle crushing device to solve the problems of unstable transmission system, poor heat dissipation and dust prevention in the existing technology, and to improve the stability, reliability and service life of the crushing device.

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Please refer to Figure 1-7 As shown, this utility model discloses a basalt coarse aggregate particle crushing device, comprising a frame 1, a crushing cylinder 2, a transmission system, and a vertical shaft impact crusher 3. The crushing cylinder 2 is mounted on the frame 1, and the vertical shaft impact crusher 3 is fixedly installed inside the crushing cylinder 2. The transmission system is driven and connected to the vertical shaft impact crusher 3, providing it with power. The transmission system includes a first transmission motor 41 and a second transmission motor 42. The frame 1 is provided with a transversely oriented transmission chamber 11, which serves as the basic support structure for the entire crushing device. The transmission chamber 11 provides installation and operating space for key components of the transmission system, and its transversely oriented design facilitates air circulation, providing conditions for subsequent heat dissipation design.

[0024] The crushing cylinder 2 is located above the middle of the frame 1 and is the main area for crushing basalt coarse aggregate. The rotating main shaft 31 of the vertical shaft impact crusher 3 has a large pulley 32 at one end and is placed in the transmission chamber 11. Support brackets 12 are fixedly installed on the outside of both sides of the crushing cylinder 2 and are fixedly mounted to the frame 1. The body of the first drive motor 41 is fixedly connected to one support bracket 12, and the body of the second drive motor 42 is fixedly connected to the other support bracket 12. Connecting ears 21 are fixedly installed on the front and rear sides of both sides of the crushing cylinder 2, and the connecting ears 21 are fixedly connected to the front and rear sides of the support bracket 12 through connecting arms 13. This method of fastening the dual motors through one side of the machine body makes the structure stable and reliable, reduces the impact of vibration during the crushing process on the connection between the motor and the support bracket, and ensures the stability of the transmission.

[0025] The power output ends of the first drive motor 41 and the second drive motor 42 are respectively connected to pulleys 43, which are placed downwards inside the transmission chamber 11. The large pulley 32 on the rotating main shaft 31 of the vertical shaft impact crusher 3 is connected to the pulleys 43 on the power output ends of the first drive motor 41 and the second drive motor 42 on both sides via several belts 44. The dual-motor drive provides greater power, which can meet the needs of crushing large basalt blocks and expands the application range of the crushing device.

[0026] To address the heat generated during the operation of the transmission system, a blower 5 is installed at one end of the transverse pipe of the transmission chamber 11, and an exhaust vent 110 is installed at the other end. The air outlet 52 of the blower 5 is connected to the transmission chamber 11, which can accelerate airflow, dissipate heat in a timely manner, reduce the temperature of the motor and transmission components, and extend the service life of the equipment.

[0027] Meanwhile, to prevent external dust from entering the transmission system, a dustproof structure 53 is provided on the exhaust pipe 51 of the blower 5. The dustproof structure 53 includes an annular connecting plate 531, a circular insulating metal mesh cover 532, and a circular filter cotton 533. A connecting flange 530 is provided at the air inlet end of the exhaust pipe 51 of the blower 5, and an annular holding groove 534 is provided around the inner side of the end of the connecting flange 530. The edge of the circular insulating metal mesh cover 532 is placed within the annular holding groove 534, and the circular filter cotton 533 is placed outside the insulating metal mesh cover 532. The circular connecting plate 531 is fixedly connected to the connecting flange 530, clamping the circular filter cotton 533 onto the circular insulating metal mesh cover 532 between the annular connecting plate 531 and the connecting flange 530. This dustproof structure effectively blocks external dust from entering the transmission system, ensuring the normal operation of the transmission components and reducing equipment failures.

[0028] Furthermore, the annular connecting plate 531 has a hollowed-out mesh in the middle or the middle part is hollowed out and a hollowed-out mesh 535 is installed, which not only ensures air circulation but also enhances the dustproof effect.

[0029] To facilitate the inspection and maintenance of the transmission system, the bottom of the transmission chamber 11 is provided with several inspection ports 111 and equipped with an inspection chamber door 112. When the transmission system needs to be inspected, simply open the inspection chamber door 112 to inspect and maintain the transmission system through the inspection ports 111, reducing maintenance costs. To enhance the overall strength of the equipment and improve its stability and reliability, several reinforcing plates 124 are longitudinally fixedly connected to the other side of the connecting support plate 123. Each reinforcing plate 124 is welded to the front support plate 121, the rear support plate 122, and the connecting support plate 123, respectively. This reinforcement structure can effectively disperse the impact force and vibration generated during the crushing process, protecting the motor and transmission system from damage.

[0030] The crushing drum 2 and the vertical shaft impact crusher 3 are combined to form a lower frame 1 with material discharge channels 100 on the front and rear sides of the transmission chamber 11. Conical diverter hoods 101 are respectively installed at the upper end of the transmission chamber 11 within the material discharge channels 100 on both sides. The design of the conical diverter hoods 101 guides the crushed material smoothly into the material discharge channels 100, reducing material accumulation and blockage within the transmission chamber 11 and improving crushing efficiency.

[0031] For an example, please refer to... Figure 1-7 As shown. The crushing operation process of the basalt coarse aggregate crushing device is as follows: The first drive motor 41 and the second drive motor 42 are started. The motors drive the rotating main shaft 31 of the vertical shaft impact crusher 3 to rotate at high speed through the pulley 43 and the belt 44. The basalt coarse aggregate is fed into the feed inlet of the crushing cylinder 2, and the vertical shaft impact crusher 3 begins to impact and crush the basalt. Due to the use of dual motor drive, powerful energy is provided, which can easily crush large pieces of basalt coarse aggregate.

[0032] During the crushing process, basalt is hard and generates significant impact and vibration. However, because the two motors are securely mounted on the support bracket 12 on one side of the machine body, and the crushing cylinder 2 and the support bracket 12 are tightly connected through the connecting lug 21 and the connecting arm 13, the structure is stable and reliable. This effectively reduces the impact of vibration on the connection between the motor and the support bracket, ensuring the stability of the transmission and enabling the crushing operation to proceed normally and efficiently.

[0033] The transmission system generates a large amount of heat during operation. At this time, the blower 5 starts, accelerating the airflow in the transmission chamber 11 to expel the heat in a timely manner, reducing the temperature of the motor and transmission components and extending the service life of the equipment. At the same time, the dustproof structure 53 of the air inlet 52 of the blower 5 effectively prevents dust generated during the crushing process from entering the transmission system, ensuring the normal operation of the transmission components and reducing the occurrence of equipment failures.

[0034] The crushed material is smoothly discharged through the discharge channel 100 on the lower side of the discharge direction, which is formed by the combination of the crushing cylinder 2 and the vertical shaft impact crusher 3. The conical diverter 101 guides the material to fall smoothly into the discharge channel 100, reducing the accumulation and blockage of material in the transmission chamber 11 and improving the crushing efficiency.

[0035] Equipment Maintenance and Repair: After the equipment has been running for a period of time, the transmission system needs to be inspected and maintained. At this time, simply open the maintenance door 112 at the bottom of the transmission compartment 11 and inspect the transmission system through the maintenance port 111 to check the wear condition of the belt 44, the operating status of the motor, etc. If the belt 44 is found to be severely worn, it can be replaced promptly; if any abnormality is found in the motor, further detailed inspection and repair can be carried out. This convenient and quick maintenance method reduces maintenance costs and improves equipment availability. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
