Description

Technical Field

[0001] The utility model relates to the technical field of sea mud soil making, in particular to a transmission structure of a sea mud soil making on-site mobile mixing equipment. Background Art

[0002] In recent years, with the rapid development of my country's economic construction, a large amount of sea mud is produced every year in the construction of marine engineering in coastal areas. On the one hand, this causes the spread of pollutants and damages the water environment; on the other hand, economic construction requires a large amount of earthwork, which further causes irreparable damage to the ecological environment. The contradiction between this demand and environmental pollution has become increasingly prominent, so there is an urgent need to treat sea mud to realize its resource utilization. In the process of sea mud soil making, the sea mud needs to be continuously stirred, and some curing agents, gravel, loess and other materials are added according to the characteristics of the sea mud to achieve the effect of dehydration and solidification of the sea mud.

[0003] The existing mixing equipment includes a frame, a walking device and a middle drum. The drum is equipped with a rake. The rotation of the drum drives the rake to rotate synchronously, thereby achieving the mixing or crushing of the material. The rotation of the drum is powered by a mechanical transmission structure. However, in actual applications, due to the high moisture content and high viscosity of sea mud, the resistance to the drum is increased, which requires the mechanical transmission structure to output more power to drive the drum. The existing mechanical transmission structure consists of an engine, a power distribution box and a gear box. The engine is connected to the power distribution box through a transmission shaft, and the latter is connected to the gear box through a transmission shaft. The meshing action of the gear box converts the high speed and small torque provided by the engine into the low speed and large torque required by the drum. In this case, the transmission shaft, as the weak link of the mechanical transmission structure, faces huge challenges. When the resistance required for the drum to mix the sea mud increases, the transmission shaft needs to transmit greater force. Exceeding its load range will cause it to break, affecting the service life of the transmission shaft. Once the transmission shaft breaks, the equipment will cause the broken transmission shaft to swing back and forth while continuing to operate, which will not only damage the surrounding equipment, but also may cause safety hazards to the staff. In addition, the replacement process of the broken transmission shaft is complicated, which increases the cost of use. Utility Model Content

[0004] The utility model aims to provide a transmission structure for a mobile mixing device on site for sea mud soil formation. The transmission structure is connected by gear meshing, has a compact structure, is not easily damaged during the sea mud mixing operation, has a long service life, and is highly safe.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A transmission structure for a mobile mixing device for sea mud soil making on site comprises a cavity, wherein the cavity comprises a hydraulic distribution cavity and a transmission cavity, a main input shaft is provided on the hydraulic distribution cavity, the main input shaft is connected to an engine, a main output shaft is provided on the transmission cavity, the main output shaft is connected to an external drum, the hydraulic distribution cavity and the transmission cavity are connected via a first slave output shaft, the first slave output shaft crosses the hydraulic distribution cavity and the transmission cavity, and the main input shaft transmits a first gear on the first slave output shaft through gear meshing, the first gear drives the first slave output shaft to rotate, the first slave output shaft drives the second gear to rotate synchronously, and the second gear transmits the main output shaft through gear meshing.

[0007] Preferably, a hydraulic clutch is provided on the main input shaft, and the hydraulic clutch is opened and closed by a hydraulic valve.

[0008] Preferably, a plurality of gears are arranged in the transmission cavity from top to bottom, and the gears are meshed with each other.

[0009] Preferably, at least one second slave output shaft is further provided in the hydraulic distribution chamber, and the second slave output shaft is gear-engaged with the main input shaft.

[0010] Preferably, the main input shaft, the main output shaft and the second slave output shaft all have shaft heads outside the cavity.

[0011] Preferably, a support member is provided inside the hydraulic distribution chamber, and the support member is sleeved on the periphery of the main input shaft and is rotatably connected to the main input shaft.

[0012] In the above technical solution, when the sea mud is mixed, the sea mud has high viscosity and produces great resistance to the drum, that is, a high power is required to drive the drum to rotate. The engine is directly connected to the hydraulic distribution chamber through the main input shaft, and the hydraulic distribution chamber is directly connected to the transmission chamber through the first output shaft. The connection structure between the engine and the hydraulic distribution chamber and the transmission chamber is strong and not prone to failure. Even when a large force is transmitted, the first slave output shaft will not break, and the service life of the transmission structure is increased.

[0013] By arranging a hydraulic clutch on the main input shaft, the hydraulic clutch controls the start and stop of the main input shaft through a hydraulic valve. When the hydraulic clutch is turned on, the main input shaft operates normally, driving the drum to rotate and turning and mixing the sea mud. When the hydraulic clutch stops, the main input shaft stops running and the drum stops rotating, thereby ensuring safety when not working. At the same time, the rotation of the drum in a non-working state will increase the energy consumption of the drum. In addition, since the hydraulic clutch can be turned on and off, that is, it can slip, it has a certain impact resistance. When the load on the drum is large, the hydraulic clutch device slips, plays a buffering role, and protects the components in the transmission structure. Further, by concentrating the main input shaft, the main output shaft, the first slave output shaft and the second slave output shaft in one cavity, the volume occupied is small, no tension is generated, and the power is output by different shaft heads, which is convenient to use.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] like Figures 1 to 3As shown, the transmission structure of the mobile mixing equipment for sea mud soil making on site includes a cavity 1, which includes a hydraulic distribution cavity 11 and a transmission cavity 12. A main input shaft 111 is provided on the hydraulic distribution cavity 11, and the main input shaft 111 is connected to the engine to provide power for the transmission structure. The main input shaft 111 spans the hydraulic distribution cavity 11 and leaves a shaft head 3 outside the cavity; a main output shaft 121 is provided on the transmission cavity 12, and the main output shaft 121 spans the transmission cavity 12 and leaves a shaft head 3 outside the transmission cavity 12, and is connected to an external roller through the shaft head 3. A first slave output shaft 112 is installed in the horizontal direction of one side of the main input shaft 111. The first slave output shaft 112 crosses the hydraulic distribution chamber 11 and the transmission chamber 12. When the sea mud is mixed, the sea mud has a high moisture content and high viscosity, and the resistance to the drum is large, that is, a large power is required to drive the drum to rotate. The connection structure between the engine and the hydraulic distribution chamber 11 and the transmission chamber 12 is strong and not prone to failure. Even when a large force is transmitted, the first slave output shaft 112 will not be broken, and the service life of the transmission structure is increased. A first gear 113 located in the hydraulic distribution chamber 11 and a second gear 114 located in the transmission chamber 12 are provided on the first slave output shaft 112. The first gear 113 is meshed with the third gear 1111 on the main input shaft 111. The second gear 114 is meshed with the gears on the main output shaft 121 through a plurality of fifth gears 122 from top to bottom, thereby outputting power to the main output shaft 121. The transmission ratio can be controlled by changing the radius of the second gear 114, the third gear 1111 and the fifth gear 122. A hydraulic clutch 115 is also provided on the main input shaft 111. The hydraulic clutch 115 controls the start and stop of the main input shaft 111 through a hydraulic valve 116. When the hydraulic valve 116 is turned on, the main input shaft 111 operates normally, driving the drum to rotate and turning and mixing the sea mud. When the hydraulic clutch 115 stops, the main input shaft 111 stops running and the drum stops rotating, thereby ensuring safety when not in operation. At the same time, the rotation of the drum in a non-working state will increase the energy consumption of the drum. In addition, since the hydraulic clutch 115 can be turned on and off, that is, it can slip, it has a certain impact resistance. When the load on the drum is large, the hydraulic clutch device slips, which plays a buffering role and protects the components in the transmission structure.

[0020] In this embodiment, a second slave output shaft 2 is installed in the horizontal direction on the other side of the main input shaft 111, and a shaft head 3 is left outside the cavity 1 on the second slave output shaft 2. At least one second slave output shaft 2 is provided, and a fourth gear 1112 is also provided on the main input shaft 111. The fourth gear 1112 is meshed with the sixth gear 21 of the slave input shaft. The transmission ratio can be controlled by changing the radius of the fourth gear 1112 and the sixth gear 21, so that power is transmitted to the second slave input shaft. The shaft head 3 of the second slave input shaft is connected to an external oil pump and an air-conditioning compressor or other components that need power on other equipment. The power is output by different shaft heads 3, which is convenient to use.

[0021] In a preferred embodiment, a support member 13 is provided inside the hydraulic distribution chamber 11, the bottom of the support member 13 is fixedly connected inside the hydraulic distribution chamber 11, and a through hole is provided on the top of the support member 13, and the main input shaft 111 passes through the through hole and is rotatably connected to the support frame, thereby increasing support for the main input shaft 111.

[0022] When in use, the main input shaft 111 is first driven to rotate by the engine, and the third gear 1111 on the main input shaft 111 drives the first gear 113 on the first slave output shaft 112 to rotate through gear meshing, and the first gear 113 drives the first slave output shaft 112 to rotate synchronously, thereby driving the second gear 114 to rotate synchronously, and the second gear 114 transmits the main output shaft 121 by meshing with a plurality of sixth gears 21, thereby realizing the rotation of the drum.

[0023] This embodiment is only an illustration of the concept and implementation of the utility model, and does not limit it. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
