Technical Field

[0001] The utility model relates to the technical field of fertilizer granulation equipment, in particular to an oil brushing device for a gear ring of a roller granulator. Background Art

[0002] In the production process of fertilizer, it is necessary to make powdered raw materials into granules through the rolling of a rotary drum granulator. The powdered raw materials are placed in a drum, and slurry, steam or water is sprayed into the drum through a spray pipe to increase the liquid phase of the granulated material so that it can be agglomerated into granules in the drum. In the granulation process, the existing drum granulator (such as a drum for producing fertilizer disclosed in application number 201220443506.6) drives the gear to rotate through a motor. Since the gear is engaged with the gear ring fixedly sleeved on the drum, when the gear rotates, the drum can be driven to rotate through the gear ring to achieve granulation. In order to ensure the smoothness of the gear and gear ring meshing transmission, it is necessary to regularly add lubricating oil to the gear and gear ring. Due to the lack of a corresponding filling mechanism, the method of manually adding lubricating oil is generally adopted. On the one hand, when the drum needs to add lubricating oil to the gear and gear ring during rotation, it is more dangerous. On the other hand, manually adding lubricating oil is also more troublesome. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The utility model provides an oil brushing device for the gear ring of a drum granulator, and its structure is as follows: Figure 1 - Figure 4 As shown, it includes an oil storage mechanism 100, an oil brushing mechanism 200 and a driving mechanism 300, the oil storage mechanism 100 includes an oil storage tank 110 for storing lubricating oil; the oil brushing mechanism 200 includes a first brush 210 corresponding to a gear or a gear ring; the driving mechanism 300 is connected to the first brush 210, and is used to drive the first brush 210 to reciprocate between a first position and a second position, when the first brush 210 is located at the first position, it contacts the lubricating oil in the oil storage tank 110, and when the first brush 210 is located at the second position, it contacts one of the gears or the gear ring.

[0025] When in use, by manipulating the driving mechanism 300, the driving mechanism 300 can drive the first brush 210 to reciprocate between the first position and the second position. When the first brush 210 reaches the first position, it can dip into the lubricating oil stored in the oil storage tank 110. When the first brush 210 reaches the second position, it can brush oil to the corresponding gear or gear ring. Since the gear and the gear ring are meshing for transmission, when the gear or gear ring is brushed with oil, as the gear and gear ring rotate, the oil will be all over the tooth grooves of the gear and gear ring, thereby realizing self-brushing of the gear and gear ring. It is no longer necessary to manually brush the gear and gear ring with oil, thus avoiding the problem of manual injury to people when brushing the gear and gear ring with oil during the rotation of the drum. In addition, it is more convenient to use the present oil brushing device to brush the gear and gear ring with oil, thereby reducing the labor intensity of workers.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 4 The oil brushing mechanism 200 also includes a second brush 220 corresponding to the gear ring. The driving mechanism 300 is also connected to the second brush 220, and is used to drive the second brush 220 to reciprocate between the third position and the fourth position. When the second brush 220 is located at the third position, it contacts the lubricating oil in the oil storage tank 110. When the second brush 220 is located at the fourth position, it contacts the other of the gear or the gear ring. The gear can be oiled by the first brush 210, and the gear ring can be oiled by the second brush 220, which can improve the oil brushing effect on the gear and gear ring.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 4 The oil storage tank 110 is arranged directly below the gears and the gear rings to receive the oil dripping from the gears and the gear rings. It can collect the lubricating oil dripping from the gears and the gear rings so that the lubricating oil can be reused, avoiding the oil on the gears and the gear rings from dripping to the ground and causing waste of lubricating oil.

[0028] As a preferred embodiment, please refer to Figure 4The gear is rotatably arranged in the oil storage tank 110 so that the first brush 210 can brush the gear with oil.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 4 The two rotating shafts 230 are arranged along the axial direction or radial direction of the drum. At this time, both the first brush 210 and the second brush 220 have a good oil brushing effect.

[0032] As a preferred embodiment, please refer to Figure 2 and Figure 3The driving mechanism 300 includes two transmission gears 310, two racks 320, a connecting frame 330 and a telescopic driving member 340.

The two ends of the connecting frame 330 are respectively fixedly connected to the two racks 320. The output end of the telescopic driving member 340 is fixedly connected to one of the racks 320, and is used to drive the corresponding rack 320 to move along the oil storage tank 110. The radial movement of the rotating shaft 230 is achieved by manipulating the telescopic driving member 340, so that the telescopic driving member 340 can drive the corresponding rack 320 to move radially along the rotating shaft 230. Since the two racks 320 are connected by the connecting frame 330, the movement of the two racks 320 is synchronized, so that the two transmission gears 310 can rotate in the same direction and at the same speed, and drive the first brush 210 and the second brush 220 to rotate in the same direction and at the same speed, so as to realize the synchronous dipping and brushing of the first brush 210 and the second brush 220 in oil.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 3 The oil storage mechanism 100 also includes two slide rails 120, and the two slide rails 120 are fixed on the side walls of the oil storage tank 110. The two racks 320 are respectively slidably set on the corresponding slide rails 120. The movement of the racks 320 can be guided by the slide rails 120, so that the movement of the racks 320 is more stable.

[0035] As a preferred embodiment, please refer to Figure 2 and Figure 3The distance between the rotating shaft 230 fixedly connected to the first brush 210 and the liquid level of the lubricating oil in the oil storage tank 110 is smaller than the distance between the rotating shaft 230 fixedly connected to the second brush 220 and the liquid level of the lubricating oil in the oil storage tank 110, and the distance between the first brush 210 and the rotating shaft 230 fixedly connected thereto is smaller than the distance between the second brush 220 and the rotating shaft 230 fixed thereto. Since the lowest point of the gear in the drum granulator is lower than the lowest point of the gear ring, and the rotation angle of the first brush 210 and the second brush 220 are The rotation angle is the same, the distance from the rotating shaft 230 fixedly connected to the first brush 210 to the liquid level of the lubricating oil in the oil storage tank 110 is set to be smaller than the distance from the rotating shaft 230 fixedly connected to the second brush 220 to the liquid level of the lubricating oil in the oil storage tank 110, and at the same time, the distance from the first brush 210 to the rotating shaft 230 fixedly connected thereto is set to be smaller than the distance from the second brush 220 to the rotating shaft 230 fixed thereto, which can ensure that the first brush 210 and the second brush 220 can be dipped in oil and brushed with oil at the same time.
