DETAILED DESCRIPTION

[0022] The utility model will be further explained in the following with the attached drawing and embodiment, and the mode of the utility model includes but is not limited to the following embodiment.

[0023] Example 1:

[0024] As Figures 1-3The utility model provides a breaker and coal breaker bearing external automatic cooling device, including: breaker / coal breaker body, breaker / coal breaker body includes drive motor 1, casing 2 and installs bearing seat 3 on both sides of casing 2, installs the broken roll in casing 2, and the both ends of the rotating shaft 4 of broken roll passes through casing 2 and is connected with bearing seat 3, wherein one end of rotating shaft 4 is connected with the output shaft of drive motor 1, and other structures in the breaker / coal breaker body are not repeated here, and the cooling mechanism is arranged on both sides of casing 2, and the cooling mechanism includes the protective cover 7 installed on the side of casing 2, the fan blade 5 is equipped in protective cover 7, the fan blade 5 is set fixed on the rotating shaft 4, the fan blade 5 includes two first half ring plates 51, and the two first half ring plates 51 are connected and fixed to form a fan blade 5 and are fixed on the rotating shaft 4, and the first half ring plate 51 is provided with a fan blade assembly on at least one side, that is, the fan blade 5 has single side and double side two structure forms, Figure 3 The middle is double side fan blade structure form, the fan blade assembly includes a plurality of fan blades fixed on the first half ring plate 51, the fan blade is arc leaf 511 or strip leaf 512, and the strip leaf 512 is a straight plate type, when the breaker / coal breaker body operates, the drive motor 1 drives the rotating shaft 4 to rotate, so that the broken roll rotates to break the coal block in the casing 2, at the same time, the rotating shaft 4 drives the fan blade 5 to rotate, when the single side fan blade 5 is provided with the arc leaf 511 on the side facing the bearing, the single side fan blade 5 can generate directional airflow on one side during rotation, and the bearing parts in the specific direction are blown, and the bearing parts are cooled in a targeted manner; if the double side fan blade 5 is provided with the arc leaf 511 on both sides, airflow can be generated on both sides at the same time, the airflow coverage range is expanded, and the cooling effect of the bearing in all directions is enhanced; if the double side fan blade 5 is provided with the arc leaf 511 on the side close to the bearing and the strip leaf 512 on the other side, the arc leaf 511 can better guide the airflow to carry away heat, and when the strip leaf rotates, the strip leaf can blow air to the surrounding, and the single side or double side design can also be flexibly matched according to actual requirements, for example, the single side fan blade 5 is used on the side with limited space, and the double side fan blade 5 is used on the other side with larger space.

[0025] By installing the protective cover 7 on the side close to the bearing and the fan blade 5 with diversified structure design, a plurality of heat dissipation modes are provided, the bearing temperature can be reduced, the bearing can be kept in a suitable working temperature range, the service life of the lubricating grease and the bearing is effectively prolonged, the damage of dust to the bearing is reduced, and the stability of equipment operation is improved.

[0026] Example 2:

[0027] As Figure 2As shown, inclined dust discharge ports 6 are opened on both sides of the housing 2. The dust discharge ports 6 are connected to the protective cover 7, and multiple baffles 9 are installed inside the dust discharge ports 6. The airflow discharged from the protective cover 7 is guided by the baffles 9 and blown towards the dust discharge ports 6, and enters the interior of the housing 2 from the dust discharge ports 6. In other words, the hot air discharged from the bearing part will enter the housing 2 and be discharged along with the crushed material as the crusher / coal crusher operates. The baffles 9 can prevent the crushed material inside the housing 2 from entering the protective cover 7.

[0028] By setting an inclined dust outlet 6 and a baffle plate 9, hot air can be sent into the machine casing 2 and materials can be prevented from entering the protective cover 7.

[0029] Example 3:

[0030] like Figure 2 As shown, a temperature sensor 8 is installed on the bearing housing 3. The temperature sensor 8 is a PT100 sensor with a detection range of -150-500℃. The temperature sensor 8 is connected to an external display device to display the real-time temperature of the bearing housing 3, thereby indirectly obtaining the approximate temperature of the bearing. When the temperature is too high (exceeding the normal operating range of the bearing), the operating parameters of the coal crusher can be adjusted manually or automatically, or other auxiliary cooling measures can be taken to ensure the normal operation of the bearing.

[0031] By installing a temperature sensor 8 on the bearing housing 3, the bearing temperature can be easily detected, so that appropriate measures can be taken in a timely manner to ensure the normal operation of the bearing.

[0032] Example 4:

[0033] like Figure 3 As shown, in this embodiment, a connecting part 52 is installed on the first semi-ring plate 51, and a connecting hole 521 is formed on the connecting part 52. By using screws to pass through the connecting holes 521 on the two first semi-ring plates 51, the two first semi-ring plates 51 can be connected into one piece to form a fan blade 5, and the fan blade 5 is sleeved and fixed on the rotating shaft 4. With this structural design, when disassembling and replacing the fan blade 5, it is not necessary to disassemble the bearing seats 3 at both ends, making it more convenient to use.

[0034] By installing the connecting part 52 on the first half ring plate 51 and opening the connecting hole 521, the replacement and maintenance of the fan blade 5 can be facilitated. Working principle: in use, when the crusher / coal crusher body is running, the driving motor 1 drives the rotating shaft 4 to rotate, so that the crushing roller rotates to crush the coal blocks in the shell 2. At the same time, the rotating shaft 4 drives the fan blade 5 to rotate. When the fan blade 5 is single-sided, the arc-shaped blade 511 is installed on the side facing the bearing, which can generate directional airflow on one side during rotation, blow air to the bearing part in a specific direction, and target cooling of the bearing part. When the fan blade 5 is double-sided, if arc-shaped blades 511 are installed on both sides, airflow can be generated on both sides at the same time, expanding the airflow coverage and enhancing the all-around cooling and dust prevention effect of the bearing. When the fan blade 5 is double-sided, if arc-shaped blades 511 are installed on the side close to the bearing, and strip-shaped blades 512 are installed on the other side, the arc-shaped blades 511 can better guide the airflow to carry away heat, and the strip-shaped blades can blow air to the surrounding area when rotating, cooling the surrounding area.
