DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0023] like Figures 1 to 6 As shown, the embodiment of the utility model provides a three-stage transmission planetary reduction mechanism, including: a ring gear fixing seat 11, a large ring gear 12, a planetary disc 13, a planetary carrier 14, a sun pinion 15 and a planetary pinion 16; the ring gear fixing seat 11 is sleeved with a large ring gear 12, and two planetary discs 13 and a planetary carrier 14 are stacked in sequence from top to bottom in the large ring gear 12, and a plurality of planetary pinions 16 are inserted at the top of each planetary disc 13 and the planetary carrier 14 for circumferential rotation, and the outer side of the planetary pinion 16 is meshed with the large ring gear 12, wherein the inner side of the planetary pinion 16 on the planetary disc 13 at the top is meshed with the sun pinion 15, and the sun pinion 15 is sleeved on the output end of the external motor 5, and the upper and lower planetary discs 13, as well as the planetary carrier 14 and the adjacent planetary disc 13 are meshed with the inner side of the planetary pinion 16 through the axial teeth 131, and the planetary carrier 14 is connected to the external transmission shaft 7 for transmission through the axial hole. When the planetary reduction mechanism 1 is used, the sun pinion 15 is driven to rotate by the output of the motor 5, and the first planetary disk 13 on the top is driven to rotate by meshing with the planetary pinion 16 and meshing with the large gear ring 12. Then the first planetary disk 13 drives the planetary pinion 16 on the second planetary disk 13 to rotate through the axial teeth 131 at the bottom of its T-shaped structure, and then drives the second planetary disk 13 to rotate under the meshing transmission of the large gear ring 12. Similarly, the second planetary disk 13 drives the planetary carrier 14 to rotate, and the planetary carrier 14 drives the drill bit 8 through the transmission shaft 7 to complete the drilling operation. Therefore, the three-stage transmission planetary reduction mechanism 1 designed as above can have the advantages of greater output torque, large transmission ratio, smooth transmission and low noise. In addition, compared with the traditional large gear reduction device, the sun pinion 15 and the planetary pinion 16, two planetary disks 13 and a planetary carrier 14 are arranged in the mounting sleeve 4 of the motor 5, so that the structure is more compact and the assembly space volume can be reduced as a whole.

[0025] The cross-section of the planetary disc 13 and the planetary carrier 14 is arranged in a T-shaped structure, so that the axial teeth 131 that mesh with each other are axially arranged at the bottom of the planetary disc 13 and the planetary carrier 14 .

[0026] There are four planetary pinions 16 arranged circumferentially, and the transmission is more stable.

[0027] The large gear ring 12 is clamped with the gear ring fixing seat 11 via a key groove 111 and a key block 121 .

[0028] A plurality of key slots 111 are circumferentially formed on the inner wall of the gear ring fixing seat 11 , and a plurality of key blocks 121 are circumferentially formed on the outer wall of the large gear ring 12 , so as to ensure that no rotation occurs between the large gear ring 12 and the gear ring fixing seat 11 .

[0029] The gear ring fixing seat 11 is locked and connected to the mounting sleeve 4 of the external motor 5 by bolts, and a locking washer 18 is pressed between the mounting sleeve 4 and the top of the large gear ring 12 to ensure that the large gear ring 12 does not produce axial movement during installation, thereby improving the stability during operation.

[0030] The embodiment of the utility model also provides a lithium battery modified anchor machine, including: a frame 2, a handle 3, a mounting sleeve 4, a motor 5, a transmission cylinder 6, a transmission shaft 7, a drill bit 8 and the planetary reduction mechanism 1 as described above; a handle 3 is provided on the top of the frame 2, and a mounting sleeve 4 is provided at the bottom of the frame 2. The motor 5 and the planetary reduction mechanism 1 are installed in the mounting sleeve 4 from top to bottom in sequence, and the bottom of the mounting sleeve 4 is locked with a transmission cylinder 6 by bolts, and a transmission shaft 7 is rotatably inserted in the transmission cylinder 6 through a bearing, and the upper end of the transmission shaft 7 is clamped with the output end of the planetary reduction mechanism 1 (that is, the axial key hole of the planetary frame 14 at the bottom is clamped with the upper end of the key shaft of the transmission shaft 7), and the lower end of the transmission shaft 7 is detachably clamped with a drill bit 8.

[0031] In order to facilitate power supply and startup control, a lithium battery pack 9 and a control panel 10 are also included. The lithium battery pack 9 is installed in a battery holder of the frame 2, and the control panel 10 is arranged on the frame 2.
