Description

Technical Field

[0001] This utility model belongs to the technical field of dual-purpose excavators, specifically relating to a dual-purpose excavator with a power mortar pump system. Background Technology

[0002] Dual-purpose excavators are engineering equipment that can travel on land and float on water. They are widely used in complex water-land interface environments such as swamps, tidal flats, and shallow water areas. The power slurry pump system is one of the functional modules of this type of equipment. It achieves efficient suction and discharge of mud through hydraulic drive, and works with the excavator body to complete terrain modification or silt removal tasks.

[0003] However, existing dual-purpose excavators have some shortcomings in complex water and land environments: on the one hand, the pontoons are mostly installed with rigid connections or manual adjustments, making it difficult to achieve precise control of the pontoon height and rapid raising and lowering, resulting in low efficiency in switching between water and land modes. Furthermore, in soft or wet environments, insufficient control of the buoyancy balance point can easily lead to problems such as equipment tilting or sinking, severely limiting the excavator's adaptability and operating efficiency in complex terrains where water and land meet, such as swamps and tidal flats. Therefore, the applicant proposes a dual-purpose excavator with a power mortar pump system to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a dual-purpose excavator with a power mortar pump system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Dual-purpose excavators equipped with a power mortar pump system include:

[0007] The hull has an excavator body located at the top center, a mud pump mechanism located in the inner cabin, multiple wheels arranged in a linear array on both sides of the hull, and pontoons located on both sides of the hull.

[0008] The hull has multiple mounting slots symmetrically opened on both sides. The top sides of the two pontoons are fixedly installed with connecting seats. The hull is located in each of the multiple mounting slots and is provided with a lifting adjustment mechanism connected to the adjacent connecting seat.

[0009] The mud pump mechanism includes a diesel engine installed in the hull of the ship. A mud pump body is installed on one side of the diesel engine. Both ends of the mud pump body are connected to transmission pipes, and the ends of the two transmission pipes away from the mud pump body extend to the outside of the hull through sealed bushings.

[0010] Preferably, the lifting and adjusting mechanism includes a connecting rod disposed on the top of the connecting seat, and the connecting rod is H-shaped. The bottom two ends of the connecting rod are rotatably connected to the top of the connecting seat. Two lugs are rotatably connected in a vertical array on the outside of the connecting rod. Two mounting plates are symmetrically fixedly installed on the side of the lugs away from the connecting rod. Two lugs are fixedly installed on the side of each mounting plate away from the lugs. A support plate is rotatably connected to the end of each lug away from the mounting plate. The side of each support plate away from the lug is fixedly installed to the inner wall adjacent to the mounting groove.

[0011] Preferably, the upper end of the connecting rod is rotatably connected to one of the ear seats via a rotating shaft. A hydraulic rod is provided on one side of the connecting rod, and rotating blocks are fixedly installed at both ends of the hydraulic rod. One of the rotating blocks is rotatably connected to the middle of the outer side of the rotating shaft, and a rotating rod is rotatably connected to the other rotating block. A connecting plate is fixedly installed at both ends of the rotating rod, and the side of the two connecting plates away from the rotating rod is fixedly installed to the inner wall adjacent to the mounting groove.

[0012] Preferably, a fixing plate is fixedly installed on the adjacent sidewalls of two adjacent mounting plates.

[0013] Preferably, valves are installed on the outside of both transmission pipes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The hydraulic rod serves as the power source. It is connected to the rotating shaft and the rotating rod fixed to the inner wall of the mounting groove through the rotating blocks at both ends. When it extends or retracts, it drives the connecting rod to rotate around the bottom, forming a stable lever effect. The H-shaped structure of the connecting rod and the rotating connection design of the ear seat one and ear seat two, together with the fixed connection between the support plate and the inner wall of the mounting groove, ensure the structural stability during the movement, so that the pontoon can be raised and lowered. By adjusting the draft, the amphibious mode can be quickly switched: when operating on water, the pontoon moves down to increase buoyancy and prevent the hull from tilting; when moving on land, the pontoon moves up to reduce resistance and ensure smooth movement, improve the adaptability of the equipment in complex terrain, and realize seamless conversion of amphibious operations.

[0016] (2) The coordinated operation of the excavator body and the mud pump enhances the equipment's ability to operate in complex environments. The excavator body can independently complete conventional excavation tasks, while the mud pump mechanism inside the ship is driven by a diesel engine and uses a transmission pipe to complete the efficient suction and discharge of mud. The valves at both ends realize flow control, so that the two can work independently or work together to handle complex working conditions, thereby improving work efficiency. The sealed bushing ensures the airtightness of the mud transportation process and avoids leakage and contamination of the ship's inner cabin, making the dual-purpose excavator exhibit stronger adaptability and operational stability in complex water-land interface environments such as wet and soft conditions.

[0027] Example 1:

[0028] Please see Figures 1-6 As shown, a dual-purpose excavator with a power mortar pump system includes: a hull 3, an excavator body 4 located at the top center of the hull 3, a mud pump mechanism 2 located in the inner compartment of the hull 3, multiple wheels 5 arranged in a linear array on both sides of the hull 3, and float boxes 6 located on both sides of the hull 3.

[0029] The hull 3 has multiple mounting slots 7 symmetrically opened on both sides. The top sides of the two pontoons 6 are fixedly installed with connecting seats 8. The hull 3 is located in the multiple mounting slots 7 and is respectively provided with a lifting adjustment mechanism 1 connected to the adjacent connecting seat 8.

[0030] The mud pump mechanism 2 includes a diesel engine 201 installed in the inner compartment of the hull 3. A mud pump body 202 is installed on one side of the diesel engine 201. Both ends of the mud pump body 202 are connected to transmission pipes 203, and the ends of the two transmission pipes 203 away from the mud pump body 202 extend to the outside of the hull 3 through sealed bushings.

[0031] As can be seen from the above, by setting up wheels 5 and pontoons 6, and by arranging multiple wheels 5 in a linear array on both sides of the longitudinal centerline of the hull 3, personnel can move by sitting inside the excavator body 4 and starting multiple wheels 5, so that the entire excavator can be moved to the required work area. At the same time, personnel can use the diesel engine 201 to drive the hydraulic rods 109 in multiple lifting and adjusting mechanisms 1 to perform a vertical movement operation, so as to move the pontoons 6 on both sides of the excavator, which can be lowered and lowered into the water at the bottom of the ship, supporting the entire hull 3 without tilting, so that the excavator has amphibious operation capability. By adjusting the draft of the pontoons 6, the rapid conversion from land walking mode to water floating mode can be achieved.

[0032] With the mud pump body 202 in place, the diesel engine 201 can start the mud pump body 202. The transmission pipes 203 connected to both ends of the mud pump body 202 are responsible for sucking and discharging mud. One end sucks in mud from outside the hull 3 through a sealed bushing, and the other end discharges mud, realizing efficient mud transportation and sealing. By integrating an independent power mud pump system inside the hull 3, the excavator can independently perform conventional excavation tasks, or work in conjunction with the built-in mud pump, improving the adaptability and efficiency of the dual-purpose excavator in complex water-land interface environments such as swamps and tidal flats.

[0033] For details, please refer to Figure 4 As shown, the lifting adjustment mechanism 1 includes a connecting rod 101 disposed on the top of the connecting seat 8, and the connecting rod 101 is H-shaped. The bottom two ends of the connecting rod 101 are rotatably connected to the top of the connecting seat 8. Two ear seats 102 are rotatably connected in a vertical array on the outside of the connecting rod 101. Two mounting plates 104 are symmetrically fixedly installed on the side of the ear seats 102 away from the connecting rod 101. Ear seats 205 are fixedly installed on the side of the two mounting plates 104 away from the ear seats 102. Support plates 106 are rotatably connected to the end of the two ear seats 205 away from the mounting plates 104. The side of the two support plates 106 away from the ear seats 205 is fixedly installed on the inner wall adjacent to the mounting groove 7.

[0034] The upper end of the connecting rod 101 is rotatably connected to one of the ear seats 102 via a rotating shaft 110. A hydraulic rod 109 is provided on one side of the connecting rod 101. A rotating block 108 is fixedly installed at both ends of the hydraulic rod 109. The interior of one rotating block 108 is rotatably connected to the middle of the outside of the rotating shaft 110. The interior of the other rotating block 108 is rotatably connected to a rotating rod. A connecting plate 103 is fixedly installed at both ends of the rotating rod. The side of the two connecting plates 103 away from the rotating rod is fixedly installed to the inner wall adjacent to the mounting groove 7.

[0035] As can be seen from the above, through the setting of the hydraulic rod 109, the hydraulic rod 109 is connected to the rotating shaft 110 and the rotating rod respectively through the rotating blocks 108 at both ends. When the hydraulic rod 109 extends or retracts, the rotating blocks 108 rotate around the rotating shaft 110 or the rotating rod, driving the connecting rod 101 to move. The bottom of the connecting rod 101 is rotatably connected to the connecting seat 8 at the top of the float box 6, and the top is connected to the ear seat 102 through the rotating shaft 110. The extension and retraction force of the hydraulic rod 109 is transmitted through the rotating shaft 110, causing the connecting rod 101 to rotate around the bottom, forming a lever effect. Ear seat one 102 is connected to ear seat two 105 through the mounting plate 104. Ear seat two 105 is rotatably connected to the support plate 106, while the support plate 106 is fixed to the inner wall of the mounting groove 7. The rotation of the connecting rod 101 drives the ear seat one 102 and ear seat two 105 to move, thereby adjusting the height of the pontoon 6. The extension and retraction of the hydraulic rod 109 controls the angle of the connecting rod 101, causing the pontoon 6 to rise and fall along the mounting groove 7, adjusting the draft. When the pontoon 6 moves down, it increases buoyancy to assist in water operations. When it moves up, it reduces resistance to adapt to land walking, realizing a rapid switching between amphibious and land modes.

[0036] For details, please refer to Figure 5 As shown, a fixing plate 107 is fixedly installed on the adjacent sidewalls of two adjacent mounting plates 104.

[0037] As can be seen from the above, by setting the fixing plate 107, the fixing plate 107 can provide a stable support for the two mounting plates 104, making the mounting plates 104 more stable when moving.

[0038] refer to Figure 2 As shown, valves 204 are installed on the outside of both transmission pipes 203.

[0039] As can be seen from the above, the setting of valve 204 facilitates personnel to control the switching of valve 204 to switch the transmission pipe 203 to transmit mud.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
