Description

Technical Field

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

[0002] The existing compost turning machine is widely used in organic fertilizer plants, compound fertilizer plants, sludge landfills, gardening fields, Agaricus bisporus cultivation fields and other fermentation and moisture removal operations. It is currently the most widely used fermentation compost turning equipment, including a frame, with walking devices at the bottom of both sides of the frame, rollers connected between the frames, and rakes on the rollers. The materials are stirred or crushed by the rakes rotating synchronously driven by the rotation of the rollers, and the rollers are driven to turn through a mechanical transmission structure.

[0003] However, in the process of sea mud soil making, due to the high moisture content and high viscosity of sea mud, the resistance to the roller will increase accordingly, which requires the mechanical rotating structure connected to the roller to provide high-power output to the roller. The existing mechanical transmission structure consists of an engine, a power distribution box and a gearbox. The engine is connected to the power distribution box through a transmission shaft, and the latter is connected to the gearbox through a transmission shaft. The meshing action of the gearbox converts the high speed and small torque provided by the engine into the low speed and large torque required by the roller. 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 stir the sea mud increases, the transmission shaft needs to transmit greater force, which will exceed its load range and cause fracture, 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.

[0004] In addition, the prior art sets hydraulic cylinders at both ends of the roller, and realizes the lifting and lowering of the roller by extending or shortening the hydraulic cylinders. The structure is simple, but when in use, since the equipment adopts a unilateral drive, the fixed end of the hydraulic cylinder on one side is fixed on the frame, and the movable end is fixed on the transmission box; the fixed end of the hydraulic cylinder on the other side is fixed on the frame, and the movable end is directly connected to the side plate of the roller. When in use, due to the heavy weight of the transmission box, the weight of one side of the transmission box is nearly ten times that of the other side, and in order to keep the roller in a horizontal state, it is necessary to ensure that the hydraulic cylinders on both sides are kept in synchronous lifting and lowering. However, due to the large weight difference at both ends, in order to achieve a balance of 10 times the hydraulic difference, the hydraulic accuracy requirements are very high, and imported parts need to be used, which increases the cost. At the same time, the cleanliness requirements for the hydraulic oil are also very high. In addition, the operating environment of the equipment is complex, and the hydraulic oil needs to be replaced more frequently, which further increases the cost. And when mixing sea mud, due to the high moisture content and viscosity of sea mud, the resistance encountered by the drum during rotation increases, and the two ends of the drum are easily subjected to unbalanced force when lifting and lowering, causing the drum to tilt. Once the drum tilts, the gear shaft connecting the drum and the gear box will be damaged or even broken, which will directly affect the service life of the equipment. Utility Model Content

[0005] The utility model aims to provide a frame for a mobile mixing device on site for sea mud soil formation, the frame for the mobile mixing device on site for sea mud soil formation has a stable structure, is not easily damaged during the sea mud mixing operation, has a longer service life, and reduces maintenance costs and use costs, and has a compact structure and high safety.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A frame for on-site mobile mixing equipment for sea mud soil formation comprises a support frame, a first connecting plate and a second connecting plate are respectively provided on the left and right sides of the support frame, a roller is connected between the first connecting plate and the second connecting plate, a walking device is provided below the support frame, and a transmission assembly is also provided on the support frame, a main input shaft and a main output shaft are provided on the transmission assembly, the main input shaft and the main output shaft are meshedly connected by gears, an engine is connected to the main input shaft, and the roller is connected to the main output shaft, and the engine provides power to the roller through the transmission assembly; a guide assembly is provided between the support frame and the walking device, and hydraulic cylinders are provided between the two sides of the walking device and the first connecting plate and the second connecting plate.

[0008] Preferably, the guide assembly includes a positioning column and a guide sleeve cooperating with the positioning column. The walking device is connected to the positioning column, and a guide sleeve is correspondingly provided on the support frame. The guide sleeve is arranged on the periphery of the positioning column and slides up and down along the positioning column driven by the hydraulic cylinder.

[0009] Preferably, the guide assembly is provided with two groups, one group of guide assemblies is connected to the first connecting plate, and the other group of guide assemblies is connected to the second connecting plate. Fixed plates are respectively provided on both sides of the walking device, the positioning column is fixedly connected to the fixed plate on the same side, and the guide sleeve is fixedly connected to the first connecting plate or the second connecting plate on the same side.

[0010] Preferably, at least two hydraulic cylinders are connected to each of the first connecting plate and the second connecting plate.

[0011] Preferably, two hydraulic cylinders are connected to the first connecting plate and the second connecting plate, and the two hydraulic cylinders are respectively arranged on the front and rear sides of the guide sleeve; the cylinder end of the hydraulic cylinder is fixedly connected to the first connecting plate or the second connecting plate, and the piston rod end of the hydraulic cylinder is rotatably connected to the fixed plate on the same side.

[0012] Preferably, the walking device is a crawler track arranged on both sides of the support frame; a fixed plate is provided on the side of the crawler track close to the hydraulic cylinder, and an auxiliary support plate is provided on the side of the crawler track away from the hydraulic cylinder; one side of the positioning column is connected to the fixed plate, and the other side is connected to the auxiliary support plate.

[0013] Preferably, a first slave output shaft is also provided on the transmission assembly, a first gear is provided on the main input shaft, a second gear and a third gear are provided on the first slave output shaft, the second gear is meshingly connected to the first gear, and the third gear is meshingly connected to the main output shaft via a plurality of fourth gears.

[0014] Preferably, the fourth gears are meshed and connected sequentially from top to bottom.

[0015] Preferably, a hydraulic clutch is provided on the main input shaft, and the hydraulic clutch is opened and closed by a hydraulic valve.

[0016] Preferably, the transmission assembly is further provided with at least one second slave output shaft, a fifth gear is provided on the main input shaft, and a sixth gear on the second slave output shaft is meshingly connected with the fifth gear.

[0017] In the above technical solution, due to the high viscosity of sea mud, the resistance to the roller is relatively increased. In the process of lifting the roller alone, the roller will be tilted due to the unequal resistance of the sea mud on both ends of the roller, and the main output shaft between the roller and the transmission structure will break. By directly connecting the roller to the support frame, the roller and the support frame always remain relatively still. Even if the support frame is skewed, the roller and the transmission assembly will be skewed with the skew of the support frame, that is, the angle between the roller and the transmission assembly will not change, and there will be no bending force, and the transmission shaft connecting the transmission assembly and the roller will not be damaged. In addition, there is no need for high-precision hydraulic oil and synchronous valves, and there is no need for frequent oil changes, which reduces maintenance costs and usage costs. Further, by setting a guide assembly between the support frame and the walking device, the support frame is guided and connected to avoid changes in the position between the support frame and the walking device during the lifting of the hydraulic cylinder.

[0018] The engine is connected to the drum through a transmission assembly, and the transmission assembly is connected to the drum through gear meshing. When the sea mud is mixed, the sea mud has high viscosity and produces great resistance to the drum, that is, a large 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.

[0019] By setting 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, 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. BRIEF DESCRIPTION OF THE DRAWINGS

When the drum 6 turns the sea mud, the resistance it encounters from the sea mud is relatively strong. When the drum 6 is lifted or lowered alone, under extreme working conditions, the two ends of the drum are easily tilted. By respectively providing a first connecting plate 11 and a second connecting plate 12 on the left and right sides of the support frame 1, the outer drum 6 is connected between the first connecting plate 11 and the second connecting plate 12, and the drum 6 is directly connected to the support frame 1, so that the drum 6 and the support frame 1 always remain relatively still.

[0027] A walking device is provided below the support frame 1, and a guide assembly 3 is provided between the support frame 1 and the walking device to guide and connect the support frame 1. Hydraulic cylinders 4 are provided between the two sides of the walking device and the first connecting plate 11 and the second connecting plate 12, and the support frame 1 and the roller 6 are synchronously raised or lowered by the extension and contraction of the hydraulic cylinders 4. The guide assembly 3 further includes a positioning column 31 and a guide sleeve 32 matched with the positioning column 31. The walking device is connected to the positioning column 31, and a guide sleeve 32 is correspondingly provided on the support frame 1. The guide sleeve 32 is sleeved on the periphery of the positioning column 31, and slides up and down along the positioning column 31 under the drive of the hydraulic cylinder.

[0028] In this embodiment, the guide assembly 3 is provided with two groups, one group of guide assemblies 3 is connected to the first connecting plate 11, and the other group of guide assemblies 3 is connected to the second connecting plate 12. Fixed plates 51 are provided on both sides of the walking device, the positioning column 31 is fixedly connected to the fixed plate 51 on the same side, and the guide sleeve 32 is fixedly connected to the first connecting plate 11 or the second connecting plate 12 on the same side.

The transmission assembly 2 also includes a first slave output shaft 214. When the sea mud is mixed, the sea mud has a high moisture content and high viscosity, which creates great resistance to the drum, i.e., a large power is required to drive the drum to rotate. The connection structure between the engine and the transmission assembly, as well as within the transmission assembly, is strong and not prone to failure. Even when a large force is transmitted, the first slave output shaft 214 will not break, thereby increasing the service life of the transmission structure. A first slave output shaft 214 is installed in the horizontal direction on one side of the main input shaft 211, a first gear 2111 is provided on the main input shaft 211, a second gear 2141 and a third gear 2142 are provided on the first slave output shaft 214, the first gear 2111 is meshed with the second gear 2141, the third gear 2142 is meshed with the seventh gear 2121 on the main output shaft 212 through a plurality of fourth gears 22 from top to bottom, thereby outputting power to the main output shaft 212, and the transmission ratio can be controlled by changing the radius of the first gear 2111, the second gear 2141, the third gear 2142, the fourth gear 22 and the seventh gear 2121. A hydraulic clutch 2113 is also provided on the main input shaft 211. The hydraulic clutch 2113 controls the start and stop of the main input shaft 211 through a hydraulic valve 2114. When the hydraulic valve 2114 is turned on, the main input shaft 211 operates normally, driving the drum 6 to rotate, and performing the turning and mixing operation on the sea mud. When the hydraulic clutch 2113 stops, the main input shaft 211 stops running, and the drum 6 stops rotating, thereby ensuring safety when not in operation. At the same time, the rotation of the drum 6 in the non-working state will increase the energy consumption of the drum 6. In addition, since the hydraulic clutch 2113 can be turned on and off, that is, it can slip, it has a certain impact resistance. When the load on the drum 6 is large, the hydraulic clutch device slips, which plays a buffering role and protects the components in the transmission structure.

[0029] In this embodiment, a second slave output shaft 215 is installed in the horizontal direction on the other side of the main input shaft 211, and the second slave output shaft 215 has a shaft head outside the cavity 21.
