Description

Technical Field

[0001] The utility model relates to the technical field of planetary reducers, in particular to a planetary reducer for a mixer. Background Art

[0002] Mixers often require powerful drive systems to effectively mix and blend feed, food, chemicals or other materials.

[0003] The reducer needs to be lubricated regularly during use. However, when lubricating the reducer in the prior art, the staff is required to open the machine cover and manually apply lubricant to the transmission parts in the machine cover. Manual application of lubricant requires shutdown and requires special staff to operate. Such operation is time-consuming and leads to low production efficiency, especially if frequent lubrication and maintenance are required. In addition, the lubrication process also requires disassembly and assembly of the machine cover, which is not convenient enough.

[0004] Therefore, it is necessary to design a planetary reducer for the mixer to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 The planetary reducer for a mixer comprises a reducer body 1, an oil filling pipe 2 is fixed inside the reducer body 1, a plurality of oil filling ports 3 are opened on the oil filling pipe 2, an oil filling barrel 4 is fixed on the outer surface of the reducer body 1, a lift plate 5 which can be raised and lowered is arranged in the oil filling barrel 4, two guide rods 6 are fixed to the inner surface of the oil filling barrel 4, the lift plate 5 is slidably sleeved on the two guide rods 6, a rotating assembly and a limit assembly are arranged on the lift plate 5, a connecting pipe 14 is arranged on the oil filling barrel 4, one end of the connecting pipe 14 is connected with the oil filling barrel 4, and the other end is connected with the oil filling pipe 2.

[0025] Reference Figure 4 The rotating assembly includes a rotating plate 7, a plurality of through holes 1 8, a plurality of through holes 2 9 and a connecting rod 10. The rotating plate 7 is rotatably assembled on the lifting plate 5. The plurality of through holes 1 8 are all provided on the rotating plate 7, the plurality of through holes 2 9 are all provided on the lifting plate 5, the connecting rod 10 is fixed on the rotating plate 7, and the connecting rod 10, the rotating plate 7 and the lifting plate 5 are coaxially located. The staff can realize automatic filling of lubricant through the relative positions of the plurality of through holes 1 8 and the plurality of through holes 2 9.

[0026] Reference Figure 5 The limiting assembly includes a fixing rod 11 and a limiting rod 12. The fixing rod 11 is fixed on the outer peripheral surface of the rotating plate 7, and the limiting rod 12 is fixed on the top surface of the lifting plate 5. The limiting assembly limits the rotation angle of the rotating plate 7. The limiting rod 12 is located on the rotation path of the fixing rod 11. When the fixing rod 11 contacts the limiting rod 12, the plurality of through holes 8 are just opposite to the plurality of through holes 2 9.

[0027] Reference Figure 4 A handle 13 is installed at one end of the connecting rod 10 away from the rotating plate 7, so that the staff can rotate the connecting rod 10 through the handle 13 conveniently.

[0028] Reference Figure 2 A transmission component is provided inside the reducer body 1, and a plurality of oil filling ports 3 are arranged toward the transmission component in the reducer body 1, so that the lubricant can be evenly distributed on the transmission component in the reducer body 1, thereby ensuring the lubricating effect of the lubricant on the reducer body 1.

[0029] Reference Figure 4 The outer surface of the lifting plate 5 and the inner surface of the oil filling barrel 4 fit each other, which can ensure the pressurization effect of the lifting plate 5 on the lubricant.

[0030] The specific working principle of the utility model is as follows:

[0031] When the planetary reducer for a mixer proposed by the utility model is in use and it is necessary to lubricate the reducer body 1, the staff first turns the handle 13, and uses the handle 13 to drive the connecting rod 10 to rotate, and the rotating plate 7 will also rotate accordingly. When the rotating plate 7 rotates, the fixed rod 11 can rotate with the rotating plate 7, and the limiting rod 12 is located on the rotation path of the fixed rod 11. When the fixed rod 11 contacts the limiting rod 12, the plurality of through holes 1 8 just face the plurality of through holes 2 9. Further, the staff pours the lubricant into the oil filling barrel 4. At this time, the lubricant will flow into the inner bottom of the oil filling barrel 4 through the plurality of through holes 1 8 and the plurality of through holes 2 9 that overlap with each other. When the lubricant completely flows into the inner bottom of the oil filling barrel 4, the staff reverses the handle 13 to make the rotating plate 7 rotate in the opposite direction. Until the plurality of through holes 1 8 and the plurality of through holes 2 9 are staggered with each other, then, at this time, the rotating plate 7 blocks the plurality of through holes 2 9. Further, the staff member presses down the handle 13 to move the lifting plate 5 downward, and uses the lifting plate 5 to squeeze the lubricant in the oil filling barrel 4. Since the plurality of through holes 1 8 and the plurality of through holes 2 9 are staggered with each other at this time, the lubricant cannot pass through the plurality of through holes 1 8 and the plurality of through holes 2 9, but will enter the interior of the oil filling pipe 2 through the connecting pipe 14 under the pressure of the lifting plate 5 and the rotating plate 7. Then, the lubricant will flow to the transmission components in the reducer body 1 through the plurality of oil filling ports 3, thereby lubricating the reducer body 1. The lubrication process does not require the reducer body 1 to be disassembled and assembled, the operation is convenient, and the uniformity of the lubricant distribution can be ensured.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
