Description

Technical Field

[0001] This utility model relates to the technical field of speed reducers for concrete mixing, and in particular to a speed reducer for concrete mixing. Background Technology

[0002] A concrete mixing plant is a type of engineering machinery that mixes cement, gravel, sand, and other materials into concrete. The reducer it uses mainly consists of a housing, a planetary carrier assembly, planetary carrier support bearings, and a screw bevel assembly.

[0003] The output shaft of existing motors can only reduce speed on shafts parallel to it, which limits their applicability. They cannot reduce speed on shafts perpendicular to them, which is not conducive to widespread adoption. Therefore, we have proposed a speed reducer for concrete mixing plants to solve the problems mentioned above.

[0004] The existing patent (publication number: CN213176742U) belongs to the field of speed reducers, specifically a speed reducer for concrete mixing plants. Addressing the limitation that existing motor output shafts can only reduce speed on parallel shafts, thus restricting their applicability and hindering widespread adoption, this invention proposes the following solution: A speed reducer housing is provided, with a chamber on the housing. A motor output shaft is rotatably mounted on the top inner wall of the chamber, and a vertical shaft is rotatably mounted on the bottom inner wall of the chamber, with a driving connection between the vertical shaft and the motor output shaft. A horizontal shaft is rotatably mounted on one inner wall of the chamber, also with a driving connection to the motor output shaft. This invention allows the motor output shaft to simultaneously drive both the horizontal and vertical shafts, enabling its application in various situations and broadening its applicability, thus facilitating widespread adoption.

[0005] To address the aforementioned issues, existing patents offer solutions. During operation, speed reducers require lubricating oil to prevent wear on the internal gears. However, existing speed reducers are not convenient for users to guide the lubricating oil into their interiors. Furthermore, the surface of existing speed reducers has ventilation holes that are not shielded, allowing dust to easily enter the speed reducer and potentially causing damage.

[0006] Therefore, a reducer for concrete mixing is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a reducer for concrete mixing, which can solve the problems of existing reducers requiring lubricating oil during use to prevent wear of the gears inside the reducer, the inconvenience for users to guide the lubricating oil into the reducer, and the lack of obstruction of ventilation holes on the surface of existing reducers, which allows dust to easily enter the reducer and cause damage.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a reducer for concrete mixing, comprising a reducer body, a ventilation hole on the top of the reducer body, a filling hole on the top of the reducer body, a filling component fixedly connected to the top of the reducer body, and a ventilation component fixedly connected to the top of the reducer body.

[0009] The filling assembly includes a storage box, an electric telescopic rod body is fixedly connected to the top of the storage box, a connecting rod is fixedly connected to the bottom of the electric telescopic rod body, a sealing block that mates with the filling hole is fixedly connected to the bottom of the connecting rod, a circular hole is opened on the top of the storage box, and a sealing cap is threaded into the inside of the circular hole.

[0010] Preferably, a baffle is fixedly connected inside the ventilation hole, and a number of heat dissipation holes are opened on the top of the baffle.

[0011] Preferably, the top plate of the baffle is fixedly connected to a frame, the front side of the frame is provided with an insertion hole, the left and right sides of the inner wall of the insertion hole are provided with slots, a filter screen frame is inserted into the insertion hole, and the left and right sides of the filter screen frame are fixedly connected with a locking block that cooperates with the slot.

[0012] Preferably, a rotating block is fixedly connected to the front side of the frame, and a limit block is rotatably connected to the surface of the rotating block.

[0013] Preferably, the storage box has several heating wires fixedly connected inside.

[0014] Preferably, a protective cover is fixedly connected to the top of the storage box, and the protective cover is fitted onto the surface of the electric telescopic rod body.

[0015] Preferably, the surface of the reducer body is coated with a corrosion-resistant layer, and the surface of the corrosion-resistant layer is coated with a waterproof layer.

[0016] Preferably, the inner wall of the reducer body is coated with a ceramic coating, and the inner wall of the ceramic coating is coated with a molybdenum disulfide coating.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, through the cooperation of the storage box, the electric telescopic rod body, the connecting rod, and the sealing block, allows users to easily control the lubricating oil filling process without complicated operations, improving the convenience of filling. The amount of lubricating oil added can be precisely controlled as needed, avoiding overfilling or underfilling, ensuring that the gears inside the reducer are adequately lubricated, and reducing lubricating oil waste. When no lubricating oil is being added, the sealing block works in conjunction with the filling hole to effectively prevent dust and other impurities from entering the reducer through the filling hole, protecting the cleanliness of the reducer's interior. The automated filling method saves manpower and time, improves work efficiency, reduces equipment downtime caused by lubricating oil, and timely and appropriate lubricating oil can reduce wear on the gears inside the reducer, extend the service life of the reducer, and reduce maintenance costs.

[0019] 2. In this application, the baffle, frame, and filter screen in the ventilation assembly work together to effectively reduce dust from entering the reducer body through the ventilation holes. The filter screen blocks dust, preventing damage to the internal components of the reducer. Several heat dissipation holes on the baffle work in conjunction with the ventilation holes to help dissipate heat inside the reducer body, keeping the reducer operating at its normal operating temperature and improving its operational stability and reliability. The filter screen can be easily snapped into the insertion hole through the cooperation of the locking block and the locking slot. At the same time, the setting of the rotating block and the limiting block facilitates the fixing of the filter screen, making the installation and replacement of the filter screen more convenient. By reducing the amount of dust entering the reducer, the internal environment can be kept clean, reducing the wear and corrosion of gears, bearings, and other components caused by dust, extending the service life of the reducer. Good ventilation and dust prevention help maintain a stable internal environment of the reducer, ensuring the stability of various performance indicators of the reducer, and improving its working efficiency and quality.

[0029] A reducer for concrete mixing includes a reducer body 1, a ventilation hole 2 and a filling hole 3 on the top of the reducer body 1, a filling component 4 and a ventilation component 5 fixedly connected to the top of the reducer body 1.

[0031] In this embodiment: by providing ventilation holes 2, it can be used in conjunction with ventilation components 5 to reduce dust from entering the reducer body 1; by providing filling holes 3, it can be used in conjunction with filling components 4 to facilitate the delivery of lubricating oil into the reducer body 1; by providing ventilation components 5, it can reduce dust from entering the reducer body 1; by providing filling components 4, it can facilitate the delivery of lubricating oil into the reducer body 1; and by providing storage boxes 401, electric telescopic rod bodies 402, connecting rods 403, and sealing blocks 404... The circular hole 405 and the sealing cover 406 allow the user to remove the sealing cover 406 from inside the circular hole 405, then guide lubricating oil into the inside of the storage box 401, then thread the sealing cover 406 to the circular hole 405, then operate the electric telescopic rod body 402 to operate the connecting rod 403, then move the sealing block 404 away from the inside of the circular hole 405, and then guide the lubricating oil inside the storage box 401 into the inside of the reducer body 1 through the filling hole 3 opened on the top of the reducer body 1.

[0032] Specifically, such as Figure 3 As shown, a baffle 501 is fixedly connected inside the ventilation hole 2, and several heat dissipation holes 502 are opened on the top of the baffle 501.

[0033] Specifically, such as Figure 3 As shown, a frame 503 is fixedly connected to the top plate of the baffle 501. An insertion hole 504 is provided on the front side of the frame 503. A slot 505 is provided on the left and right sides of the inner wall of the insertion hole 504. A filter screen frame 506 is inserted into the insertion hole 504. A locking block 507 that cooperates with the slot 505 is fixedly connected to the left and right sides of the filter screen frame 506.

Then, the filter frame 506 inside the plug hole 504 on the front side of the frame 503 reduces the amount of dust that is led into the reducer body 1 through the several heat dissipation holes 502. The locking block 507 and the slot 505 can help the filter frame 506 to be locked inside the plug hole 504.

[0041] In this embodiment: by setting the corrosion-resistant layer 8 and the waterproof layer 9, the corrosion of the reducer body 1 by rainwater or dust can be reduced. By setting the ceramic coating 10 and the molybdenum disulfide coating 11, the reducer body 1 can be made easier to operate.

[0042] Working principle: When the reducer needs to be lubricated, the user controls the electric telescopic rod body 402 to control the connecting rod 403, which then moves the sealing block 404 away from the inside of the circular hole 405. This allows the lubricant inside the storage box 401 to be guided into the reducer body 1 through the filling hole 3 on the top of the reducer body 1.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
