Description

Technical Field

[0001] This invention relates to the field of solidified soil preparation technology, specifically to an excavation mixer. Background Technology

[0002] Stabilized soil is made by adding certain stabilizers to the soil to stabilize it. In order to ensure the stability of infrastructure construction in deep water environments, stabilized soil is widely used in pile foundation manufacturing to reduce the damage caused by seawater erosion to the pile foundation, while ensuring the progress of offshore infrastructure construction. Stabilized soil is prepared directly on the ship deck.

[0003] The preparation of solidified soil requires two processes: mixing and transportation. Therefore, during the preparation of solidified soil, workers arrange for an excavator equipped with a customized mixing hopper to be brought to the site. Apart from the special hopper, the excavator's structure is the same as that of existing land excavators. When ships sail on the sea, they sway from side to side with the waves, and the excavator located on the ship's surface will also sway, causing the excavator to shift and the hopper's position to become unpredictable. This increases the difficulty of operation for workers, making the preparation of solidified soil difficult and affecting the subsequent construction of marine infrastructure. While welding a support structure to resist the swaying has some effect, it changes the structure of the entire excavator, increasing the space required for storage. This results in a large space being needed for storage when the excavator is not in use, which is not conducive to practical use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an excavating mixer that is easy to operate in swaying marine environments, has high stability, a simple overall structure, and is inexpensive. It solves the problem that traditional excavators are not suitable for working in marine environments, which affects the efficiency of solidified soil preparation.

[0005] The present invention provides the following technical solution: an excavator mixer, including an excavator chassis, an adjustment component movably connected inside the excavator chassis, a support component movably connected to the adjustment component, a limit component fixedly installed at the end of the support component, and a connecting component movably connected to the support component, the connecting component and the adjustment component being connected through the limit component.

The auxiliary connecting rod is movably connected to the first connecting seat through the first connecting shaft. The adjusting assembly also includes a second connecting seat fixedly installed on the side of the excavator chassis. A second connecting shaft is movably connected inside the second connecting seat. The end of the auxiliary connecting rod away from the first connecting seat is movably connected to the second connecting seat through the second connecting shaft.

[0007] Preferably, the support assembly includes an energy-absorbing spring disposed inside the support assembly. A second connecting plate is fixedly connected to the end of the energy-absorbing spring away from the inner cavity of the support assembly. A support rod is fixedly installed on the side of the second connecting plate away from the energy-absorbing spring. A first connecting plate is fixedly installed at the end of the support rod. The side of the first connecting plate away from the support rod is fixedly connected to a limiting assembly. The support assembly and the second connecting seat are movably connected through a second connecting shaft, and the support assembly is disposed above the auxiliary connecting rod.

[0008] Preferably, the limiting component includes an arc-shaped hole and a central shaft disposed inside the limiting component and movably connected to the limiting component. An adjusting lever is fixedly mounted on the surface of the central shaft. The adjusting lever passes through the limiting component and is slidably connected to the arc-shaped hole. A first magnet is embedded in the side of the adjusting lever. A second magnet is embedded in the inner wall of the arc-shaped hole near the first magnet. The first magnet and the second magnet are arranged with the same poles corresponding to each other. A connecting round shaft is disposed on the surface of the central shaft. A connecting rod is movably disposed on the connecting round shaft. The connecting rod is in the shape of a straight line. A limiting slider is slidably disposed on the limiting component. The limiting slider and the connecting rod are movably connected through the connecting round shaft. The limiting component has a sealed design.

[0009] Preferably, the connecting assembly includes a movable cylinder disposed on and movably connected to the support assembly, and a connecting block fixedly connected to the limiting assembly. A return spring is fixedly installed on the bottom surface of the inner cavity of the movable cylinder, and the end of the return spring is fixedly connected to the connecting assembly. The connecting assembly is slidably connected to the movable cylinder. An arc-shaped groove is formed on the side of the connecting assembly adjacent to the connecting block. An auxiliary shaft is movably connected to the side of the connecting block near the connecting assembly, and an auxiliary rod is fixedly connected to it. The connecting assembly and the connecting block are rotatably connected through the auxiliary shaft. The auxiliary rod contacts the inner surface of the arc-shaped groove and is slidably connected to the arc-shaped groove. The connecting block and the auxiliary connecting rod are connected through the limiting assembly.

[0010] Preferably, a drive module is provided below the excavator chassis, and a control module and a robotic arm module are respectively provided above the excavator chassis, with a mixing and excavating hopper provided at the end of the robotic arm module.

[0011] Preferably, the adjusting component has a buffer block inside for protecting the threaded rod, and the outer surface of the adjusting component has a drive worm gear for connecting with the power output shaft inside the excavator chassis.

[0012] Preferably, there are two support components, which are symmetrically arranged on both sides of the excavator chassis.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This excavator mixer, by adding support components on both sides of the excavator chassis to make additional connections with the structure on the ship's deck, utilizes the shock absorption performance of the internal structure of the support components to reduce the impact of the ship's swaying on the sea surface, thereby improving the stability of the entire excavator. Furthermore, since the excavator chassis is a fixed structure on the excavator, placing the support components in this position will not affect the normal use of the excavator, ensuring the timeliness of the solidified soil preparation and avoiding any impact on the overall marine infrastructure project.

[0015] 2. This excavating mixer connects the adjustment component and the support component through a connecting assembly. This allows the user to flexibly adjust the position of the support component using the adjustment assembly. Ship deck structures can have various configurations, including flat and inclined surfaces. Therefore, the adjustment assembly enhances its adaptability, enabling the entire device to change its structural state according to actual usage conditions. This reduces the space required when the excavator is stationary, avoiding waste due to the already limited space on the ship. At the same time, it makes the overall device more rational and suited to actual usage conditions.

[0016] 3. This excavator mixer, by adding limiting components to the connecting components and the supporting components respectively, can quickly fix the supporting components to the structure of the ship's deck by utilizing the internal structure of the limiting components, thereby improving the tightness of the connection between these structures and the ship, thus ensuring the stability of the entire excavator during operation. Furthermore, the connecting components and the limiting components work together. When the excavator is stationary, the supporting components can be fixed to the side of the excavator chassis to limit the position of the supporting components and prevent the supporting components from swinging arbitrarily, which could cause safety hazards.

The connecting assembly 5 includes a movable cylinder 501 disposed on the support assembly 2 and movably connected to the support assembly 2, and a connecting block 503 fixedly connected to the limiting assembly 3.A return spring 502 is fixedly installed on the bottom surface of the inner cavity of the movable cylinder 501. The end of the return spring 502 is fixedly connected to the connecting assembly 5. The connecting assembly 5 is slidably connected to the movable cylinder 501. An arc-shaped groove 506 is provided on the side of the connecting assembly 5 adjacent to the connecting block 503. An auxiliary shaft 504 is movably connected to the side of the connecting block 503 near the connecting assembly 5, and an auxiliary rod 505 is fixedly connected to it. The connecting assembly 5 and the connecting block 503 are rotatably connected through the auxiliary shaft 504. The auxiliary rod 505 contacts the inner surface of the arc-shaped groove 506 and is slidably connected to the arc-shaped groove 506. The connecting block 503 and the auxiliary connecting rod 404 are connected through the limiting assembly 3, making the overall structure more flexible and allowing for timely adjustments to each component according to actual usage.

[0028] Working principle: The adjusting component 4, which is movable inside the excavator chassis 1, is connected to the power output shaft inside the excavator chassis 1 via a drive worm gear 408. Rotation of the adjusting component 4 causes the threaded rod 401, which is threaded inside, to move outward from the excavator chassis 1. A first connecting seat 402 is fixed to the end of the threaded rod 401. The first connecting seat 402 is movably connected to an auxiliary connecting rod 404 via a first connecting shaft 403. The end of the auxiliary connecting rod 404 is movably connected to a second connecting seat 405 via a second connecting shaft 406. The second connecting seat 405 is fixed to the side of the excavator chassis 1. Therefore, when the adjusting component 4 rotates, the threaded rod 401 pushes the first connecting seat 402 to perform a translational movement. The connecting block 503, connected to the connecting component 5 via an auxiliary shaft 504, is connected to the auxiliary connecting rod 404 via a limiting component 3. The limiting component 3 can be inserted into the auxiliary connecting rod 404 via a limiting slider 306. (See reference...) Figure 4 At this time, the support assembly 2 and the auxiliary connecting rod 404 are relatively stationary. The support assembly 2 is movably connected to the second connecting shaft 406. When the adjusting assembly 4 rotates, the support assembly 2 rotates in a circle around the second connecting shaft 406 until the end of the support assembly 2 contacts the structure on the predetermined ship deck. The adjusting lever 302, which slides through the arc-shaped hole 301, rotates together with the central shaft 304. The central shaft 304 is connected to the connecting rod 307 via the connecting round shaft 308, and the connecting rod 307 is movably connected to the limiting slider 306 that slides in the limiting assembly 3 via the connecting round shaft 308. Rotating the adjusting lever 302 allows the limiting slider 306 to be submerged into the surface of the limiting component 3. Then, the limiting component 3 is inserted into the pre-fixed structure. The adjusting lever 302 is then released. The first magnet 303 and the second magnet 305 are respectively embedded on the side opposite to the arc-shaped hole 301. The first magnet 303 and the second magnet 305 are set with the same poles. The repulsive force generated by the two magnets pushes the adjusting lever 302 back to the initial position, and the limiting slider 306 pops out from inside the limiting component 3, thus completing the limiting and fixing work. The connecting component 5 and the auxiliary connecting rod 404 are operated in the same way.

[0029] At this time, the end of the support assembly 2 is fixedly connected to the structure on the deck using the limiting assembly 3, and the internal energy-absorbing spring 204 resists the force generated by the ship's rocking through its own elasticity, which can reduce the impact of rocking on the excavator. Rotating the adjusting assembly 4 in the opposite direction can retract the support assembly 2 structure with the excavator chassis 1 as the orientation. After the threaded rod 401 is completely retracted into the adjusting assembly 4, the connecting assembly 5 is connected to the movable cylinder 501 through the return spring 502, and the movable cylinder 501 is rotatably connected to the support assembly 2. Therefore, the connecting assembly 5 can be adjusted up and down, and the connecting block 503 is movably connected to the connecting assembly 5 through the auxiliary shaft 504. Furthermore, the connecting block 503 is also equipped with an auxiliary rod 505 that slides inside the arc-shaped slide groove 506. Under the action of the arc-shaped slide groove 506, the connecting block 503 can only rotate within 90 degrees with the excavator chassis 1 and the auxiliary connecting rod 404 as the boundaries. The limiting component 3 is fixed to the side of the connecting block 503. After removing the limiting component 3 from the auxiliary connecting rod 404, the connecting component 5 can be pulled upward, and then the connecting block 503 can be rotated to adjust the direction so that the limiting component 3 is inserted into the interior of the excavator chassis 1. By utilizing the connection relationship between the connecting component 5 and the support component 2, the support component 2 is restricted to the side of the excavator chassis 1.

[0030] The excavator chassis 1, drive module 101, control module 102, robotic arm module 103 and mixing excavation bucket 104 are components of an existing excavator. The excavator chassis 1 is a fixed structure in the excavator and does not rotate. The exploded labels in this article are for easy identification of the position of the excavator chassis 1. Therefore, the connection relationship between them and the specific working principle will not be described in detail in this article.
