Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a multifunctional agricultural implement quick attachment device. Background Technology

[0002] The multi-functional agricultural implement quick-connect device is a specialized device applied in the field of agricultural machinery, designed to achieve efficient and convenient connection and separation between the main unit and different types of multi-functional agricultural implements. Its core function is to significantly shorten the time for changing agricultural implements and reduce the intensity of manual operation through specific connection logic and operation mechanism. At the same time, it ensures the structural stability and operational synchronization of the main unit and agricultural implements after connection, meets the needs of rapid switching of multiple operation functions in agricultural production, and improves the comprehensive utilization rate and operational efficiency of agricultural machinery.

[0003] However, existing multi-functional agricultural implement quick-attachment devices have limited positioning accuracy between the limiting components and the implement structure, making it difficult to quickly and accurately align with the fixed part of the implement, thus prolonging the attachment time. At the same time, the attachment process relies heavily on manual force, which is physically demanding and can easily damage the implement or device components due to improper operation. This makes it difficult to achieve quick and safe attachment of agricultural implements and affects agricultural operation efficiency.

[0004] To address this, a multifunctional agricultural implement quick attachment device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-functional quick attachment device for agricultural implements, which can solve the problems of limited positioning accuracy between the limiting component and the implement structure in existing multi-functional quick attachment devices, making it difficult to quickly and accurately align with the fixed part of the implement, thus prolonging the attachment time. At the same time, the attachment process relies heavily on manual force, which is physically demanding and can easily damage the implement or device components due to improper operation. This makes it difficult to achieve quick and safe attachment of agricultural implements, thus affecting the efficiency of agricultural operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional agricultural implement quick attachment device, including an agricultural machinery mounting frame, an adjustment frame provided on the rear side of the agricultural machinery mounting frame, a limiting mechanism fixedly connected to the rear side of the adjustment frame, a fixing rod provided on the top of the limiting mechanism, a hydraulic rod provided on the top of the agricultural machinery mounting frame, an electric limiting component movably connected to the inner wall of the limiting mechanism, an implement structure provided on the rear side of the limiting mechanism, the limiting mechanism including a mounting frame, a connecting block fixedly connected to the bottom of the mounting frame, a limiting frame fixedly connected to the bottom of the connecting block, and the electric limiting component fixedly connected to the limiting frame on the side near the limiting frame.

[0007] Preferably, a fixing block is fixedly connected to the bottom of the agricultural implement structure, and a connector is fixedly connected to the front side of the fixing block.

[0008] Preferably, the surface of the connector is movably connected to the inner wall of the limiting frame, and the surface of the electric limiting assembly is inserted into the inner wall of the connector.

[0009] Preferably, a fixing plate is fixedly connected to the top of the mounting bracket, and the inner wall of the fixing plate is fixedly connected to the surface of the fixing rod.

[0010] Preferably, a hook is fixedly connected to the top of the agricultural implement structure, and the surface of the fixing rod is movably connected to the inner wall of the hook.

[0011] Preferably, a connecting frame is fixedly connected to the rear side of the agricultural machinery fixing frame, and the rear side of the connecting frame is fixedly connected to the front side of the adjusting frame.

[0012] Preferably, a rotating bracket is fixedly connected to the top of the connecting frame, and the hydraulic rod is fixedly connected to the rotating bracket on the side near the rotating bracket.

[0013] Preferably, a rotating block is fixedly connected to the rear side of the hydraulic rod, and a limit bracket is rotatably connected to the surface of the rotating block. The side of the limit bracket closest to the fixed plate is fixedly connected to the fixed plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a limiting mechanism. During use, the mounting frame and the connecting block are fixed in position, and the connecting block and the limiting frame are fixed in position, forming a stable limiting support frame. When the agricultural machinery fixing frame moves close to the implement structure, the mounting frame can drive the fixing rod to accurately align with the pre-installation part of the implement structure, achieving preliminary positioning before attachment. After the pre-installation part is engaged, the limiting frame can move close to the fixed part of the implement structure under the drive of the hydraulic rod, providing reliable support for subsequent limiting and locking. At the same time, the electric limiting component is fixed to the limiting frame and can move on the inner wall of the limiting mechanism. Its limiting component can extend and lock the fixed part of the implement structure under electric drive, effectively preventing the implement structure from shifting or falling off after attachment, and ensuring the stability of the connection between the main unit and the implement structure. 2. This application utilizes a machinery mounting frame, which serves as a connection carrier to the external machinery. Driven by the external machinery, the entire device can be brought closer to the implement structure, providing basic support for the attachment operation. This ensures the device can accurately approach the implement structure to be attached. An adjustable frame connects the machinery mounting frame and the limiting mechanism, allowing for flexible adjustment of the limiting mechanism's posture and position according to the implement structure's location. This enhances the device's adaptability to implement structures in different installation positions. A hydraulic rod, located at the top of the machinery mounting frame, provides stable driving force. This force drives the mounting frame to engage the fixing rod with the pre-installed part of the implement structure, and simultaneously drives the limiting frame closer to the fixed part of the implement structure. This replaces manual labor, reducing operational intensity. Furthermore, the smoothness of the hydraulic drive prevents damage to the implement structure or device components due to excessive impact during attachment, ensuring the safety and efficiency of the attachment operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 The present invention provides the following technical solution: A multifunctional agricultural implement quick attachment device includes an agricultural machinery mounting frame 1, an adjustment frame 3 is provided on the rear side of the agricultural machinery mounting frame 1, a limiting mechanism 2 is fixedly connected to the rear side of the adjustment frame 3, a fixing rod 4 is provided on the top of the limiting mechanism 2, a hydraulic rod 5 is provided on the top of the agricultural machinery mounting frame 1, an electric limiting component 6 is movably connected to the inner wall of the limiting mechanism 2, an implement structure 7 is provided on the rear side of the limiting mechanism 2, the limiting mechanism 2 includes a mounting frame 201, a connecting block 202 is fixedly connected to the bottom of the mounting frame 201, a limiting frame 203 is fixedly connected to the bottom of the connecting block 202, and the electric limiting component 6 is fixedly connected to the limiting frame 203 on the side near the limiting frame 203.

[0019] In this embodiment: By setting a limiting mechanism 2, the mounting frame 201 and connecting block 202 are fixed in position during use, and the connecting block 202 and limiting frame 203 are fixed in position, forming a stable limiting support frame. When the agricultural machinery fixing frame 1 moves close to the implement structure 7, the mounting frame 201 can drive the fixing rod 4 to accurately align with the pre-installation part of the implement structure 7, achieving preliminary positioning before attachment. After the pre-installation part is engaged, the limiting frame 203 can move close to the fixed part of the implement structure 7 under the drive of the hydraulic rod 5, providing reliable support for subsequent limiting and locking. At the same time, the electric limiting component 6 is fixed to the limiting frame 203 and can move within the inner wall of the limiting mechanism 2. Its limiting component can extend under electric drive and lock the fixed part of the implement structure 7, effectively preventing displacement or detachment of the implement structure 7 after attachment, ensuring the stability of the connection between the main unit and the implement structure 7. By setting an agricultural machinery fixing... The frame 1, serving as the connection carrier with the external agricultural machinery host, can drive the entire device closer to the implement structure 7 under the drive of the external agricultural machinery, providing basic mobile support for the attachment operation and ensuring that the device can accurately approach the implement structure 7 to be attached. The adjusting frame 3 connects the agricultural machinery mounting frame 1 and the limiting mechanism 2, and can flexibly adjust the posture and position of the limiting mechanism 2 according to the position of the implement structure 7, improving the adaptability of the device to implement structures 7 in different installation positions. The hydraulic rod 5 is set on the top of the agricultural machinery mounting frame 1, which can provide stable driving force. On the one hand, it drives the mounting frame 201 to drive the fixing rod 4 to connect with the pre-installation part of the implement structure 7, and on the other hand, it drives the limiting frame 203 to approach the fixing part of the implement structure 7, replacing manual force and reducing the intensity of operation. At the same time, the stability of hydraulic drive can avoid damage to the implement structure 7 or device components due to excessive impact during the attachment process, ensuring the safety and efficiency of the attachment operation.

[0020] Specifically, such as Figure 3 As shown, a fixing block 8 is fixedly connected to the bottom of the agricultural implement structure 7, and a connector 9 is fixedly connected to the front side of the fixing block 8.

[0021] Specifically, such as Figure 3 As shown, the surface of the connector 9 is movably connected to the inner wall of the limit frame 203, and the surface of the electric limit assembly 6 is inserted into the inner wall of the connector 9.

[0022] Specifically, such as Figure 3 As shown, a fixing plate 10 is fixedly connected to the top of the mounting bracket 201, and the inner wall of the fixing plate 10 is fixedly connected to the surface of the fixing rod 4.

[0023] In this embodiment: by setting the fixing block 8 and the connector 9, a dedicated connecting component can be provided for the implement structure 7 to dock with the limiting frame 203, avoiding docking deviation caused by direct contact between the implement structure 7 and the limiting frame 203. The surface of the connector 9 is movably connected to the inner wall of the limiting frame 203, which can realize the initial guiding docking between the implement structure 7 and the limiting frame 203, ensuring that the electric limiting component 6 can be accurately aligned with the connector 9. At the same time, the surface of the electric limiting component 6 is inserted into the inner wall of the connector 9, which can quickly lock the relative position between the connector 9 and the limiting frame 203, preventing the connector 9 from loosening after hanging. The fixing plate 10 fixed at the top of the mounting frame 201 is fixed to the surface of the fixing rod 4, which can stably install the fixing rod 4 on the mounting frame 201, avoiding the fixing rod 4 from shaking or shifting when moving with the mounting frame 201, ensuring that the fixing rod 4 can accurately dock with the pre-installation part of the implement structure 7, and providing a reliable guarantee for the initial positioning of the hanging operation.

[0024] Specifically, such as Figure 3 As shown, a hook 11 is fixedly connected to the top of the agricultural implement structure 7, and the surface of the fixing rod 4 is movably connected to the inner wall of the hook 11.

[0025] Specifically, such as Figure 2 As shown, a connecting frame 12 is fixedly connected to the rear side of the agricultural machinery fixing frame 1, and the rear side of the connecting frame 12 is fixedly connected to the front side of the adjusting frame 3.

[0026] In this embodiment: by setting hook 11, temporary suspension support can be formed for the implement structure 7 in the initial stage of attachment through the cooperation of hook 11 and fixed rod 4, reducing the shaking of implement structure 7 during subsequent docking, facilitating the precise docking of connector 9 and limit frame 203. Connector 12 fixed to the rear side of the agricultural machinery fixing frame 1 and adjustment frame 3 fixed to the front side can strengthen the connection strength between agricultural machinery fixing frame 1 and limit mechanism 2, avoid connection breakage or loosening when adjustment frame 3 drives limit mechanism 2 to move, and ensure that the driving force of agricultural machinery fixing frame 1 can be stably transmitted to limit mechanism 2.

[0027] Specifically, such as Figure 5 As shown, a rotating bracket 13 is fixedly connected to the top of the connecting frame 12, and the hydraulic rod 5 is fixedly connected to the rotating bracket 13 on the side near the rotating bracket 13.

[0028] Specifically, such as Figure 5As shown, a rotating block 14 is fixedly connected to the rear side of the hydraulic rod 5. A limit bracket 15 is rotatably connected to the surface of the rotating block 14. The side of the limit bracket 15 closest to the fixed plate 10 is fixedly connected to the fixed plate 10.

[0029] In this embodiment: by setting a rotating bracket 13, the hydraulic rod 5 can rotate flexibly around the rotating bracket 13, providing multi-angle adjustment space for the hydraulic rod 5 to drive the limiting bracket 15 to move, adapting to the docking requirements of agricultural implement structures 7 with different postures. The rotating block 14 fixed on the rear side of the hydraulic rod 5 is rotatably connected to the limiting bracket 15, and the limiting bracket 15 is fixed to the fixing plate 10, so that when the hydraulic rod 5 is driven, the driving force is smoothly transmitted to the limiting bracket 15 through the rotation of the rotating block 14, avoiding the deformation of the limiting bracket 15 caused by the direct rigid push of the hydraulic rod 5. At the same time, it ensures that the limiting bracket 15 can accurately approach the fixed part of the agricultural implement structure 7 under the drive of the hydraulic rod 5, ensuring the stability and accuracy of the hooking and locking operation.

[0030] Working Principle: During the use of the agricultural machinery fixing frame 1, a limiting mechanism 2 is set up. During use, the mounting frame 201 is fixed to the position of the connecting block 202, and the connecting block 202 is fixed to the position of the limiting frame 203, forming a stable limiting support frame. When the agricultural machinery fixing frame 1 moves closer to the implement structure 7, the mounting frame 201 can drive the fixing rod 4 to precisely align with the pre-installation part of the implement structure 7, achieving initial positioning before attachment. After the pre-installation part is engaged, the limiting frame 203 can approach the fixed part of the implement structure 7 under the drive of the hydraulic rod 5, providing reliable support for subsequent limiting and locking. Simultaneously, the electric limiting component 6 is fixed to the limiting frame 203 and can move within the limiting mechanism 2. Its limiting component can extend under electric drive and lock the fixed part of the implement structure 7, effectively preventing displacement or detachment of the implement structure 7 after attachment, ensuring the stability of the connection between the main unit and the implement structure 7. A machine mounting frame 1 is installed, serving as a connection carrier to the external machine host. Driven by the external machine, the entire device can be brought closer to the implement structure 7, providing basic support for the attachment operation and ensuring precise proximity of the device to the implement structure 7. An adjusting frame 3 connects the machine mounting frame 1 and the limiting mechanism 2, allowing for flexible adjustment of the limiting mechanism 2's posture and position according to the implement structure 7's location, improving the device's adaptability to implement structures 7 in different installation positions. A hydraulic rod 5 is located at the top of the machine mounting frame 1, providing stable driving force. On one hand, it drives the mounting frame 201 to engage the fixing rod 4 with the pre-installed part of the implement structure 7; on the other hand, it drives the limiting frame 203 to approach the fixed part of the implement structure 7, replacing manual labor and reducing operational intensity. Simultaneously, the stability of the hydraulic drive prevents damage to the implement structure 7 or device components due to excessive impact during attachment, ensuring the safety and efficiency of the attachment operation.
