Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a hydraulic motor mounting and locking device for multiple accessories of farmland water channels. Background Art

[0002] After a period of use, farmland ditches require various operations, such as mowing, weeding, salvaging, and dredging, to clean them. The traditional method is manual cleaning, which is inefficient and labor-intensive. Currently, a more efficient method is to use a robotic arm on a walking chassis to drive various attachments (such as mowing, weeding, salvaging, and dredging), thereby achieving efficient and automated cleaning of farmland ditches.

[0003] However, when replacing different attachments, the hydraulic motor—the power source—is integrated with the attachment. Disassembling and replacing the attachment requires disconnecting the hydraulic lines connected to the motor, which inevitably leads to hydraulic oil leaks. This not only wastes hydraulic oil but also easily contaminates farmland waterways. Furthermore, hydraulic motors are not universal, requiring a separate motor for each attachment, increasing the cost of using the attachments. Utility Model Content

[0025] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0026] like Figure 1-6As shown, the utility model discloses a hydraulic motor mounting and locking device for multiple attachments of farmland canals, comprising a hydraulic motor 1, a quick locking bolt 2 and a base 3 that can be connected to different attachments. The base 3 is a universal base and has an L-shaped structure. One side of the base is provided with a mounting side plate 31. The mounting side plate 31 is provided with a side plate connecting hole 311 connected to the motor mounting hole 11 of the hydraulic motor 1. The center of the mounting side plate 31 is provided with a motor output shaft extension hole 312. The output shaft of the hydraulic motor 1 extends from the motor output shaft extension hole 312 and is connected to the gears, couplings, cams and other transmission gears on the attachment. The dynamic parts cooperate, and the quick locking bolt 2 includes a handle nut 21, a locking plate 22, a locking plate driving rod 23, and a bolt rod 24 that can be inserted into the motor mounting hole 11 and the side plate connecting hole 311. The handle nut 21 is threadedly connected to the outer wall of one end of the bolt rod 24, and the locking plate driving rod 23 is slidingly connected to the inner hole 241 of the bolt rod 24. The locking plate 22 is hinged to the side wall hole 242 at the other end of the bolt rod 24 and is driven to rotate in and out of the side wall hole 242 by the locking plate driving rod 23, thereby playing a limiting role, and then cooperating with the handle nut 21 to lock, and the hydraulic motor 1 is installed and fixed on the mounting side plate 31. When the bolt rod 24 of the utility model is inserted into the motor mounting hole 11 and the side plate connecting hole 311, the locking plate 22 rotates inward. After being inserted into the motor mounting hole 11 and the side plate connecting hole 311, the locking plate 22 rotates outward, driving the handle nut 21 to rotate, thereby reducing the distance between the handle nut 21 and the locking plate 22, and then firmly mounting the hydraulic motor 1 on the mounting side plate 31. The entire process only requires manual tightening, which is fast and efficient. At the same time, it also avoids the problem of hydraulic oil leakage caused by disassembling the hydraulic pipeline, avoids waste of hydraulic oil and pollution of farmland water channels. Further, by disassembling the hydraulic motor 1, the hydraulic motor 1 can be used universally on different accessories.

[0027] In this embodiment, in order to facilitate pressing the locking plate drive rod 23, the quick locking bolt 2 also includes a bolt handle 25 connected to one end of the bolt rod 24. The bolt handle 25 includes an index finger hook plate 251 and a middle finger hook plate 252 arranged on both sides to cooperate with the index finger and middle finger respectively. The index finger hook plate 251 and the middle finger hook plate 252 are C-shaped structures, which are ergonomic and convenient for pressing the locking plate drive rod 23 downward to immerse the locking plate 22 into the side wall hole 242.

[0028] In this embodiment, the locking plate 22 includes a locking paddle 221 and a locking wing 222 that are vertically integrated. The locking paddle 221 and the locking wing 222 are generally L-shaped. The locking wing 222 is hinged to the two side walls of the side wall hole 242. The other end of the locking plate driving rod 23 is provided with a convex ring 231 that drives the locking paddle 221 to reciprocate. When the convex ring 231 moves downward, the locking wing 222 is driven to swing inward, and then into the side wall hole 242, so as to facilitate the insertion of the bolt rod 24 into the motor mounting hole 11 and the side plate connecting hole 311. When the convex ring 231 moves upward, the locking wing 222 is driven to swing outward, and then outside the side wall hole 242, so as to facilitate the travel limit locking space between the locking wing 222 and the handle nut 21.

[0029] In this embodiment, see Figure 6 In order to make the locking wing 222 pop out automatically, the quick locking bolt 2 also includes a locking spring 26 arranged in the inner hole 241 of the bolt rod 24. One end of the locking spring 26 abuts against the bottom of the inner hole 241, and the other end abuts against the convex ring 231 to keep the end of the locking wing 222 exposed from the side wall hole 242, so that the locking wing 222 can be clamped and abutted against the outer edge of the pressure motor mounting hole 11, playing a connecting and limiting role. During operation, the locking plate driving rod 23 is pressed downward to drive the locking paddle 221, the locking spring 26 contracts, and the locking wing 222 rotates counterclockwise into the side wall hole 242, making it easier for the bolt rod 24 to be inserted into the motor mounting hole 11 and the side plate connecting hole 311. After insertion and positioning, the bolt handle 25 is released, and the convex ring 231 moves upward under the drive of the locking spring 26, and the locking wing 222 rotates clockwise to extend out of the side wall hole 242, forming a limiting step structure. At this time, the handle nut 21 can be rotated to lock.

[0030] In this embodiment, in order to make the handle nut 21 a labor-saving structure and facilitate manual locking of the hydraulic motor 1, the handle nut 21 includes a nut body 211 and a plurality of rotating rods 212 arranged axially along the nut body 211. One end of any rotating rod 212 is fixedly connected to the nut body 211, and the other end extends radially outward along the nut body 211, forming a scattered shape structure, similar to the labor-saving structure of a sailing steering wheel.

[0031] In this embodiment, a slide rail slider assembly 4 and a bottom plate 5 mounted on the slide rail slider assembly 4 are also mounted on the base 3. The hydraulic motor 1 is mounted on the bottom plate 5, and the sliding direction of the bottom plate 5 is parallel to the axis of the motor output shaft extension hole 312. Therefore, the hydraulic motor 1 can be pre-installed outside the motor output shaft extension hole 312, avoiding the high difficulty and low efficiency of manual alignment. After pre-installation, it can be pushed toward the motor output shaft extension hole 312 to reach the pre-positioned position. In this embodiment, a positioning plate 32 is provided on one side of the mounting side plate 31. A plurality of bottom plate positioning assemblies 6 are mounted on the positioning plate 32. The bottom plate positioning assembly 6 includes a positioning rod 61 that slides with the positioning plate hole 321 of the positioning plate 32. The positioning rod 61 matches the bottom plate hole 51 on the bottom plate 5, thereby achieving pre-positioning of the hydraulic motor 1 and facilitating the subsequent fast tightening of the bolt 2.

[0032] In this embodiment, to improve pre-positioning efficiency, the base plate positioning assembly 6 further includes a lever 62 and a return spring 63. The lever 62 is connected to the bottom of the positioning rod 61. One end of the return spring 63 is connected to the positioning plate 32, and the other end is connected to the lever 62. This allows the positioning rod 61 to automatically return to its original position. During operation, the lever 62 is pulled downward, and the positioning rod 61 exits the base plate hole 51, allowing the base plate 5 to be removed. When the lever 62 is released, the positioning rod 61 returns to its original position under the action of the spring.

[0033] In this embodiment, to improve the efficiency of pre-installation of the hydraulic motor 1 outside the motor output shaft extension hole 312, a longitudinal fixing block 7 is also included. The longitudinal fixing block 7 is mounted on the base plate 5 and is provided with an insertion cavity that matches the shape of the hydraulic motor 1. When the hydraulic motor 1 is inserted into the insertion cavity, the output shaft of the hydraulic motor 1 is aligned with the motor output shaft extension hole 312.
