Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to a bucket connecting seat that is easy to install and its installation method. Background Technology

[0002] As a key working attachment for construction machinery (such as loaders and excavators), the bucket is hinged to the boom and linkage mechanism (or boom) of the loader via a connecting seat, thereby completing a series of actions such as digging, lifting, and unloading. In practical applications, to meet different operational needs, a single loader often needs to be equipped with multiple buckets of different specifications and models. However, this need for versatility faces significant challenges in existing technologies.

[0003] Currently, there is a prominent contradiction in the connection method between the bucket and the vehicle body: on the one hand, due to differences in structural design and strength requirements, the distribution, spacing, and size of the connecting pins (or hinge holes) on the back of the bucket used to connect the boom and the shovel often vary; on the other hand, the geometric dimensions and relative positions of the connection points at the front ends of the boom and the shovel are fixed for loaders from different manufacturers and with different tonnages. This "double mismatch" leads to a serious problem of universality—a specific model of loader can usually only be equipped with a specific bucket whose connection point dimensions are perfectly matched, and cannot be flexibly and conveniently adapted to other models of buckets.

[0004] This lack of interchangeability causes numerous inconveniences for users. Firstly, when a bucket needs to be replaced to adapt to different working conditions, if the existing bucket's connector is incompatible with the loader, users often need to seek customized adapters or modify the connection structure on-site. This process is cumbersome, time-consuming, and labor-intensive, and may introduce safety hazards due to improper modifications. Secondly, from an equipment management perspective, this limits the effective allocation of equipment resources, reducing the overall utilization rate and economic efficiency of the equipment. For leasing companies or construction enterprises with multiple models of loaders, management costs and spare parts inventory pressure also increase accordingly. Summary of the Invention

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, an easy-to-install bucket connecting seat is used to connect the boom and bar of a loader to the connecting post 11 on the back of the bucket 1. It includes: a connecting frame 21, which has an overall frame-like structure and is arranged on the back of the bucket 1; a lower locking mechanism 22, installed at the bottom of the connecting frame 21, including two lower locking components that can move in opposite directions along the width direction of the bucket 1, each lower locking component having two lower locking heads 2211. The lower locking heads 2211 can move in a direction perpendicular to the moving direction of the lower locking components, and are used to connect with the connecting post 11 on the back of the bucket 1; and an upper locking mechanism 23, located at the top of the connecting frame 21, including two upper locking components that can move towards or away from each other along the width direction of the bucket 1, each upper locking component having two upper locking heads 2311. The upper locking heads 2311 can move in a direction perpendicular to the moving direction of the upper locking components, and are used to connect with the boom and bar of the loader.

[0030] An easy-to-install bucket 1 connecting seat is provided for connecting the boom and shovel of a loader to the connecting post 11 on the back of the bucket 1. Its structure includes a connecting frame 21, which is frame-shaped and arranged on the back of the bucket 1. A lower locking mechanism 22 is installed at the bottom of the connecting frame 21. This mechanism includes two lower locking components that can move backwards along the width direction of the bucket 1. Each component has two lower locking heads 2211, which can be adjusted perpendicular to the direction of component movement to achieve precise alignment and locking with the connecting post 11 on the back of the bucket 1. An upper locking mechanism 23 is provided at the top of the connecting frame 21. This mechanism includes two upper locking components that can move towards or away from each other along the width direction of the bucket 1. Each component is also equipped with two upper locking heads 2311, which can move vertically to connect and lock with the loader boom and shovel.

[0031] The working process is as follows: First, install the connecting frame 21 on the back of the bucket 1, and adjust the bottom locking mechanism 22 so that the lower locking head 2211 assembly and the lower locking head 2211 are aligned and locked with the connecting post 11 on the back of the bucket 1; then adjust the upper locking mechanism 23, move the upper locking head 2311 assembly and the upper locking head 2311 so that they correspond to and are locked with the boom and shovel of the loader. Through the above steps, the connection mismatch problem between different models of loaders and the bucket 1 is effectively solved.

[0032] The independent adjustment capabilities of the upper locking mechanism 23 and the lower locking mechanism 22 enable the connecting frame 21 to be quickly adapted to various models of buckets 1 and loaders, improving installation efficiency and versatility. At the same time, both the upper locking head 2311 and the lower locking head 2211 can be flexibly adjusted in multiple directions, enhancing the stability and reliability of the connection and reducing the difficulty of adjustment and maintenance costs during equipment use.

[0033] like Figures 3-6 As shown, the lower locking assembly further includes: a lower sliding plate 2212, which is slidably disposed at the bottom of the connecting frame 21 along the width direction of the bucket 1; two lower locking heads 2211 are disposed at the bottom of the lower sliding plate 2212 and can slide in opposite directions perpendicular to the sliding direction of the lower sliding plate 2212; and a lower push head 2213, which is slidably mounted on the lower sliding plate 2212 along the width direction of the bucket 1 and is located between the two lower locking heads 2211; wherein the lower push head 2213 and the lower locking heads 2211 are slidably connected by a bevel engagement.

[0034] The lower locking assembly also includes a lower sliding plate 2212, a lower pusher head 2213, and a lower locking head 2211. The lower sliding plate 2212 is slidably mounted on the bottom of the connecting frame 21 along the width direction of the bucket 1. The two lower locking heads 2211 are installed on the bottom of the lower sliding plate 2212 and can slide in opposite directions perpendicular to the sliding direction of the lower sliding plate 2212. The lower pusher head 2213 is slidably mounted on the lower sliding plate 2212 along the width direction of the bucket 1 and is located between the two lower locking heads 2211. The lower pusher head 2213 and the lower locking head 2211 are linked by a bevel engagement. When the lower pusher head 2213 is pushed to move, the bevel engagement causes the lower locking head 2211 to move laterally, thereby achieving rapid alignment and locking with the connecting post 11 on the back of the bucket 1.

[0035] The inclined planes enable the linkage adjustment of the lower push head 2213 and the lower locking head 2211. The operation is simple; simply pushing the lower push head 2213 is enough to synchronously control the opposite movement of the two lower locking heads 2211, which improves installation efficiency and enhances locking stability.

[0036] like Figures 3-6 As shown, the lower locking mechanism 22 also includes a lower double-rod hydraulic cylinder 222, which is horizontally fixed at the bottom of the connecting frame 21. The output rods at both ends of the lower double-rod hydraulic cylinder 222 are respectively connected to the two lower push heads 2213 to drive the two lower push heads 2213 to move synchronously in opposite directions.

[0037] The lower locking mechanism 22 is also equipped with a lower double-rod hydraulic cylinder 222, which is horizontally fixedly installed at the bottom of the connecting frame 21. The output rods at both ends of the lower double-rod hydraulic cylinder 222 are respectively connected to two lower push heads 2213, which can synchronously drive the two to move in opposite directions along the width direction of the bucket 1. When the output rods of the lower double-rod hydraulic cylinder 222 are output, the lower locking head 2211 is pre-locked in the side lug for installing the connecting column 11, which can prevent the lower sliding plate 2212 from sliding.

[0038] During operation, by operating the lower double-rod hydraulic cylinder 222, the two lower push heads 2213 can be precisely controlled to move synchronously in opposite directions. Then, through the inclined plane cooperation, the lower locking heads 2211 on both sides move in opposite directions, so as to achieve automatic alignment and locking with the connecting column 11 of the bucket 1.

[0039] By using a lower double-rod hydraulic cylinder 222 as the drive source, the synchronization and automation of the movement of the lower locking mechanism 22 are achieved.

[0040] like Figures 3-6 As shown, the lower push head 2213 has a lower through-hole coaxial with the output rod of the lower double-rod hydraulic cylinder 222; the output rod end of the lower double-rod hydraulic cylinder 222 has a lower connecting rod 2221 that extends coaxially and is inserted into the lower through-hole; a lower abutment ring 2222 is sleeved on the lower connecting rod 2221, and the lower abutment ring 2222 is located between the lower push head 2213 and the output rod end face of the lower double-rod hydraulic cylinder 222. The axial position of the lower push head 2213 can be adjusted by adjusting the number of lower abutment rings 2222.

[0041] The structure of the lower push head 2213 is further optimized, with a lower through-hole coaxially arranged at its center with the output rod of the lower double-rod hydraulic cylinder 222. The end of the output rod of the lower double-rod hydraulic cylinder 222 has a coaxially extending lower connecting rod 2221, which is inserted into the lower through-hole of the lower push head 2213 to achieve axial connection. A lower abutment ring 2222 is fitted onto the lower connecting rod 2221, located between the end faces of the lower push head 2213 and the output rod of the lower double-rod hydraulic cylinder 222, forming an axial limiting structure. By increasing or decreasing the number of lower abutment rings 2222, the axial installation position of the lower push head 2213 can be flexibly adjusted, thereby precisely controlling the mating clearance between it and the lower locking head 2211.

[0042] During operation, the operator can select an appropriate number of lower abutment rings 2222 for installation according to actual assembly needs, thereby fine-tuning the initial position of the lower push head 2213. This adjustment helps ensure that the inclined surface fit between the lower push head 2213 and the lower locking head 2211 is always in optimal working condition, avoiding loosening of the connection or poor movement due to wear of parts or manufacturing errors. At the same time, after adjusting the position of the lower sliding plate 2212, the output rod of the lower double-rod hydraulic cylinder 222 can still transmit thrust to the lower push head 2213 through the lower abutment rings 2222.

[0043] Through the coordinated design of the lower through-hole, lower connecting rod 2221, and lower abutment ring 2222, the axial position of the lower push head 2213 is flexibly adjustable, effectively compensating for dimensional deviations during manufacturing and assembly, and improving the adaptability and reliability of the mechanism. At the same time, this adjustment method is simple in structure and easy to operate, allowing for precise fine-tuning without replacing parts, which helps extend the equipment's service life and reduce maintenance costs.

[0044] like Figures 3-6 As shown, the two lower locking heads 2211 are provided with a bayonet 2214 at their opposite ends. The bayonet 2214 is used to radially bridging the connecting post 11. The opening diameter of the bayonet 2214 gradually increases from its inner side to its outer side.

[0045] Both lower locking heads 2211 are provided with a bayonet 2214 at their opposite ends. The bayonet 2214 is used to radially bridging and engaging with the connecting post 11 on the back of the bucket 1. To further improve the ease of docking and tolerance, the opening diameter of the bayonet 2214 is a funnel-shaped structure that gradually widens from its inner side to its outer side.

[0046] During operation, when the lower double-rod hydraulic cylinder 222 pushes the lower push head 2213 and drives the lower locking head 2211 to move in opposite directions, the gradually expanding bayonet 2214 structure can actively guide the connecting column 11 to smoothly enter the bayonet 2214 during the alignment stage. Even if there is a certain lateral or vertical positional deviation, it can achieve self-centering correction through the trumpet-shaped opening, effectively reducing the dependence on installation accuracy.

[0047] The flared bayonet design 2214 significantly improves the docking tolerance between the connecting post 11 and the locking head, simplifies the alignment operation during installation, and achieves a fast and precise connection. This not only greatly improves assembly efficiency but also reduces the manpower and time consumption caused by repeated adjustments, enhancing the adaptability and connection reliability of the equipment under different operating conditions.

[0048] like Figures 7-10 As shown, the upper locking assembly further includes: an upper sliding plate 2312, which is slidably disposed on the top of the connecting frame 21 along the width direction of the bucket 1; two upper locking heads 2311, which are slidably disposed on the bottom of the upper sliding plate 2312 in opposite directions perpendicular to the sliding direction of the upper sliding plate 2312; and an upper push head 2313, which is slidably disposed on the bottom of the upper sliding plate 2312 along the width direction of the bucket 1 and located between the two upper locking heads 2311; wherein the upper push head 2313 and the upper locking head 2311 are slidably connected by a bevel engagement.

[0049] The upper locking assembly further includes an upper sliding plate 2312, an upper pusher head 2313, and upper locking heads 2311. The upper sliding plate 2312 is slidably disposed on the top of the connecting frame 21 along the width direction of the bucket 1. Two upper locking heads 2311 are installed at the bottom of the upper sliding plate 2312 and can slide backwards along a direction perpendicular to the sliding direction of the upper sliding plate 2312. The upper pusher head 2313 is slidably disposed at the bottom of the upper sliding plate 2312 along the width direction of the bucket 1 and is located between the two upper locking heads 2311. The upper pusher head 2313 and the upper locking heads 2311 are linked by an inclined plane. When the upper pusher head 2313 is pushed to move, the inclined plane drives the two upper locking heads 2311 to move laterally synchronously, thereby achieving rapid alignment and reliable locking with the boom and handle of the loader.

[0050] This structural design maintains a similar working principle to the lower locking mechanism 22, achieving a unified operating logic. Its advantages include: the linkage between the upper push head 2313 and the upper locking head 2311 is achieved through the inclined surface cooperation, making the upper connection adjustment equally simple and efficient, ensuring the coordination and overall stability of the entire connector during installation.

[0051] like Figures 7-10 As shown, the upper locking mechanism 23 also includes an upper double-rod hydraulic cylinder 232, which is horizontally fixed on the top of the connecting frame 21; the output rods at both ends of the upper double-rod hydraulic cylinder 232 are respectively connected to the two upper push heads 2313 to drive the two upper push heads 2313 to move synchronously in opposite directions.

[0052] The upper locking mechanism 23 is also equipped with an upper double-rod hydraulic cylinder 232, which is horizontally fixedly installed on the top of the connecting frame 21. The output rods at both ends of the upper double-rod hydraulic cylinder 232 are respectively connected to two upper push heads 2313, which can synchronously drive the two to move in opposite directions or towards each other along the width direction of the bucket 1. When the output rod of the upper double-rod hydraulic cylinder 232 is output, the upper sliding plate 2312 is prevented from sliding because the boom and the end of the loader are locked in the upper locking head 2311. Then, the upper double-rod hydraulic cylinder 232 is activated to drive the two upper locking heads 2311 to lock with the boom and the loader.

[0053] During operation, by controlling the movement of the upper double-rod hydraulic cylinder 232, the two upper push heads 2313 can be precisely driven to achieve synchronous reverse movement. The upper push head 2313, through the inclined surface cooperation with the upper locking head 2311, converts the horizontal thrust into the lateral movement of the upper locking head 2311, thereby driving the upper locking heads 2311 on both sides to move in opposite directions or towards each other, realizing rapid and automatic alignment and locking with the connection point of the loader boom and shovel.

[0054] The upper double-rod hydraulic cylinder 232 is used as the drive source to realize the synchronous and automated control of the movement of the upper locking mechanism 23, ensuring precise alignment when connected to the loader.

[0055] like Figures 7-10 As shown, the upper push head 2313 has an upper through-hole coaxial with the output rod of the upper double-rod hydraulic cylinder 232; the output rod end of the upper double-rod hydraulic cylinder 232 has an upper connecting rod 2321 that extends coaxially and is inserted into the upper through-hole; an upper abutment ring 2322 is sleeved on the upper connecting rod 2321, and the upper abutment ring 2322 is located between the upper push head 2313 and the output rod end face of the upper double-rod hydraulic cylinder 232. The axial position of the upper push head 2313 can be adjusted by adjusting the number of upper abutment rings 2322.

[0056] The structure of the upper push head 2313 has been optimized accordingly, with an upper through-hole at its center that is coaxially arranged with the output rod of the upper double-rod hydraulic cylinder 232. An upper connecting rod 2321, extending coaxially, is machined to the end of the output rod of the upper double-rod hydraulic cylinder 232. This upper connecting rod 2321 is precisely inserted into the upper through-hole of the upper push head 2313, achieving reliable axial docking between the two. An upper abutment ring 2322 is fitted onto the upper connecting rod 2321. This abutment ring is located between the end faces of the upper push head 2313 and the output rod of the upper double-rod hydraulic cylinder 232, forming a crucial axial positioning structure. By increasing or decreasing the number of upper abutment rings 2322, the axial installation position of the upper push head 2313 can be flexibly and precisely adjusted, thereby fine-tuning the initial state and effective stroke of the inclined surface engagement between it and the upper locking head 2311. Meanwhile, after adjusting the position of the lower sliding plate 2212, the output rod of the lower double-rod hydraulic cylinder 222 can still transmit the thrust to the lower push head 2213 through the lower abutment ring 2222.

[0057] During operation, maintenance personnel can make compensatory fine adjustments to the axial position of the upper push head 2313 by adjusting the number of upper abutment rings 2322 according to the actual assembly clearance and wear condition. This adjustment ensures that the inclined plane transmission between the upper push head 2313 and the upper locking head 2311 is always in the optimal meshing state, effectively avoiding problems such as loose connection, stuck action, or abnormal hydraulic system pressure caused by wear of parts or manufacturing tolerances, and ensuring smooth and reliable locking action.

[0058] Inheriting the same adjustable design concept as the lower locking mechanism 22, the upper push head 2313 achieves convenient fine-tuning of its axial position through the cooperation of the upper through-hole, upper connecting rod 2321, and upper abutment ring 2322. This not only significantly improves the upper locking mechanism 23's adaptability to manufacturing errors and long-term wear, extending its service life, but also reduces maintenance costs caused by component replacement, ensuring that the upper and lower connections of the entire connecting seat have equal reliability and stability.

[0059] like Figures 7-10 As shown, the connecting frame 21 is provided with a positioning rod 211 extending along the width direction of the bucket 1, the top of the lower sliding plate 2212 is provided with a lower sliding seat 2215 that slides with the positioning rod 211, and the bottom of the upper sliding plate 2312 is provided with an upper sliding seat 2314 that slides with the positioning rod 211.

[0060] The connecting frame 21 has a positioning rod 211 extending horizontally along the width of the bucket 1 inside. A lower sliding seat 2215, which slides in conjunction with the positioning rod 211, is fixedly installed at the top of the lower sliding plate 2212. Similarly, an upper sliding seat 2314, which slides in conjunction with the positioning rod 211, is provided at the bottom of the upper sliding plate 2312. The lower sliding seat 2215 and the upper sliding seat 2314 are both mounted on the same positioning rod 211, providing stable guidance and support for the horizontal movement of the upper sliding plate 2312 and the lower sliding plate 2212.

[0061] During operation, when the dual-bar hydraulic cylinder drives the upper pusher 2313 or the lower pusher 2213 to move, the sliding plate connected to it will slide smoothly along the positioning rod 211 via the sliding seat. This guiding structure effectively limits the possible deflection or jamming of the sliding plate during movement, ensuring the accuracy and stability of its linear motion.

[0062] like Figure 10 As shown, an installation method for an easy-to-install bucket connector is applied to an easy-to-install bucket 1 connector, comprising the following steps: Step 1: Adjust the lower locking mechanism 22 by moving the lower locking component and the lower locking head 2211 so that their positions correspond to the connecting post 11 on the back side of the bucket 1 and lock them in place. Step 2: Adjust the upper locking mechanism 23 by moving the upper locking component and the upper locking head 2311 so that their positions correspond to the boom and shovel of the loader and are locked.

[0063] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
