The number of sight glass plates 2 7 can be set at 1-6 positions around the central axis according to actual needs. An oil seal 12 is mounted in an oil seal seat 11 to seal the lubricating oil in the reducer. The oil seal seat 11 is fixed on the sealing disk 5 around the axis of the sealing disk 5, and the motor base 4 and the sealing disk 5 are mounted on the support frame 3 together. The motor 10 is mounted on the upper part of the motor base 4 through a transition connecting plate 9, and is connected to the input shaft of the open reducer through a coupling (hydraulic coupling) 13. The dipstick pipe 15 is fixed to the inner ring of the slewing bearing 2 through the motor base 4, the fixed rubber sleeve 16 and the support frame 3. The inner ring of the slewing bearing 2 is provided with a lubricating oil passage, and the dipstick 17 is arranged in the dipstick pipe 15. The ventilation pipe 19 is fixed to the sealing disk 5 through the motor base 4 and the fixed rubber sleeve 2 18, and the ventilation cover 20 is fixed to the upper part of the ventilation pipe 19. The space surrounded by the open reducer 14, the support frame 3, the sealing disk 5, the oil seal seat 11 and the oil seal 12 is combined into the accommodation space 1 21. The space surrounded by the motor 10, the transition connecting plate 9, the motor base 4, the sealing disk 5 and the oil seal system is combined into the accommodation space 2 22.

[0029] The working principle of the utility model is as follows:

[0030] The slewing bearing 2 is installed on the upper part of the reducer 1 to form an open reducer 14. The reducer 1 can be a vertical planetary reducer for a mixer designed for a single-axis, double-axis or three-axis output structure. The utility model is particularly suitable for mixed vertical planetary mixer equipment such as cement building materials concrete, dry and wet mortar, etc. The support frame 3 is installed on the upper part of the inner ring of the slewing bearing 2. The support frame 3 is an important connecting part between the entire transmission system and the vertical mixer. The sight glass plate 1 6 is installed and fixed on the side of the motor base 4, and the sight glass plate 2 7 is installed on the upper part of the sealing disk 5 through the pressure cover 8. The number of the sight glass plates 2 7 can be set at 1-6 around the central axis according to actual needs. The oil filling amount inside the open reducer 14 can be seen through the sight glass plates 1 6 and the sight glass plates 2 7, ensuring that the oil filling position is more accurate and convenient for observing the internal oil amount. The oil seal 12 is installed in the oil seal seat 11, and they are combined into an oil seal system to seal the lubricating oil in the reducer 1. The oil seal seat 11 is fixed on the sealing disk 5 around the axis of the sealing disk 5. The motor seat 4 and the sealing disk 5 are installed on the support frame 3. The motor 10 is installed on the upper part of the motor seat 4 through the transition connecting plate 9, and is connected to the input shaft of the open reducer through the coupling (hydraulic coupling) 13. The transition connecting plate 9 can ensure the smooth installation of the coupling (hydraulic coupling) before installing the motor 10. The convenience and reliability of the installation of the motor 10, coupling (hydraulic coupling) 13 and other components are guaranteed.

[0031] Through the above structural design, the space enclosed by the open reducer 14, the support frame 3, the sealing plate 5, the oil seal seat 11 and the oil seal 12 is combined into a receiving space 21, a proper amount of lubricating oil is injected into the receiving space 21, and it is ensured that the oil and gas generated by the lubricating oil during the working process only exist in the receiving space 21.

[0032] Through the above structural design, the space surrounded by the motor 10, the transition connecting plate 9, the motor seat 4, the sealing plate 5 and the oil seal system is combined into the accommodation space 22. Because the lubricating oil and oil gas only exist in the accommodation space 1 21, the lubricating oil and oil gas cannot enter the accommodation space 22, and the accommodation space 22 becomes an independent clean space. The structure avoids oil and gas pollution on the side surface of the upper motor 10, the inner surface of the motor seat 4 and the coupling (hydraulic coupling) 13, and ensures that the surface of the viewing hole glass plate 16 is clean and transparent, which is convenient for observing the amount of lubricating oil in the accommodation space 1 21. At the same time, the reliability of each component of the accommodation space 22 is improved.

[0033] The dipstick pipe 15 is fixed on the inner ring of the slewing bearing 2 through the motor base 4, the fixed rubber sleeve 16 and the support frame 3. The inner ring of the slewing bearing 2 is provided with a lubricating oil passage. The dipstick 17 is arranged in the dipstick pipe 15. The arrangement of the dipstick 17 can ensure that the lubricating oil level inside the reducer can be checked at any time, and ensure that each component of the reducer is effectively and fully lubricated and cooled.

[0034] The ventilation pipe 19 is fixed on the sealing plate 5 through the motor base 4 and the fixed rubber sleeve 18, and the ventilation cover 20 is fixed on the upper part of the ventilation pipe 19. This device ensures that the internal and external air pressures of the reducer are balanced and avoids oil leakage from the oil seal 12.

[0035] In summary, the new structure fully enclosed transmission system completely solves the above-mentioned problems from a technical point of view, improves the performance of each component, makes the equipment cleaner and more environmentally friendly, and its functions safer and more reliable.

[0036] The present embodiment is applied to a vertical mixer, and the output shaft form of the vertical mixer includes a single output shaft and a multi-output shaft. The multi-output shaft includes two output shafts, three output shafts, and four output shafts, that is, in the specific implementation process, each output shaft is connected with a stirring structure (according to different names in the industry, it can be called a stirring leg, a stirring rod, a stirring arm, etc.), that is, the patent is applicable to vertical mixers such as a single output stirring leg, a double output stirring leg, a triple output stirring leg, and a quadruple output stirring leg. Among them, the single output stirring leg can be a single stirring leg, or a stirring leg based on an output shaft by any complex structure that can stir the material to achieve the target result. Similarly, the double output stirring leg, the triple output stirring leg, and the quadruple output stirring leg can also be a stirring leg of a complex structure, which can ensure that no interference occurs during use. In addition, the quadruple output stirring leg is not the limit of the vertical mixer. In other optional embodiments, a larger number of stirring leg structures that can achieve the purpose of the utility model and the stirring purpose of the vertical mixer are all acceptable.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
