Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a trenching machine for agricultural planting. Background Technology

[0002] In agricultural planting, ditching is an indispensable and crucial step in sowing, irrigation, and drainage. With the development of agricultural mechanization, various ditching equipment has been widely used, significantly improving operational efficiency and ditching quality. However, most existing ditching machines still have significant limitations, especially in terms of operational efficiency. Most ditching machines on the market currently only have single-ditch operation capability, meaning they can only complete the excavation of one ditch at a time. This is not only time-consuming but also difficult to meet the needs of large-scale, concentrated farmland operations. Furthermore, these machines often have poor adaptability to the diverse ditch spacing requirements of different planting patterns, requiring frequent replacement or adjustment of parts, making operation cumbersome and affecting overall work efficiency. Therefore, we propose a ditching machine for agricultural planting. Utility Model Content

[0003] The main purpose of this utility model is to provide a trenching machine for agricultural planting, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A trenching machine for agricultural planting includes a mounting frame, the front end of which is integrally formed with a frame, a trenching mechanism is provided inside the frame, and mounting holes are provided at all four corners of the mounting frame. The trenching mechanism includes a drive motor, which is fixedly installed on the frame. A rotating rod is fixedly connected to the output end of the drive motor. The rotating rod is movably connected to the frame via a bearing. A drive bevel gear is fixedly connected to one end of the rotating rod. The drive bevel gear is located inside the frame and has trenching units connected to its two sides respectively. The two trenching units are mounted opposite each other on the frame.

[0005] Preferably, the trenching unit includes a mounting rod, which is rotatably connected to the frame via a bearing. One end of the mounting rod is fixedly connected to a transmission bevel gear, which meshes with a drive bevel gear. Splines are integrally formed on both the upper and lower sides of the outer surface of the mounting rod, and the trenching body is detachably mounted on the mounting rod via the splines.

[0006] By adopting the above technical solution: the trenching unit includes a mounting rod, which is rotatably connected to the frame through bearings to ensure its flexible operation during operation. One end of the mounting rod is fixedly connected to a transmission bevel gear, which meshes with the drive bevel gear to transmit the power of the drive motor to the trenching unit. In addition, the upper and lower sides of the outer surface of the mounting rod are integrally formed with splines, which facilitates detachable connection with the trenching body and improves the maintenance and replacement efficiency of the equipment.

[0007] Preferably, the trenching body includes a mounting sleeve, a trenching wheel is fixedly connected to the middle of the mounting sleeve, and a keyway for cooperating with a spline is provided inside the mounting sleeve. The mounting sleeve is slidably connected to the mounting rod through the keyway.

[0008] By adopting the above technical solution: the trenching body consists of a mounting sleeve, a keyway, and a trenching wheel. The trenching wheel is fixedly connected to the center of the mounting sleeve for actual trenching operations. The mounting sleeve has a keyway inside that mates with a spline, allowing the trenching body to be slidably mounted on the mounting rod, thus achieving quick assembly and disassembly. This design not only improves assembly efficiency but also enhances the adaptability and flexibility of the equipment.

[0009] Preferably, the length of the spline is twice the length of the mounting sleeve.

[0010] By adopting the above technical solution: in order to ensure the stability and adjustment range of the trenching body on the mounting rod, the length of the spline is set to twice the length of the mounting sleeve. This proportional design can provide sufficient contact area to transmit torque, and also allow the mounting sleeve to move axially along the mounting rod, which is convenient for adjusting the trenching width and position according to different agronomic needs.

[0011] Preferably, the trenching wheel and the mounting sleeve are coaxially arranged, and the trenching wheel and the mounting sleeve are integrally formed and connected.

[0012] By adopting the above technical solution, the trenching wheel and the mounting sleeve are set with a coaxial core and are integrally formed. This can effectively avoid vibration or wear problems caused by misalignment, improve the stability and accuracy of trenching operations, and at the same time, the integrated structure reduces the number of parts, simplifies the manufacturing process, and reduces maintenance costs.

[0013] Preferably, the outer surface of the mounting sleeve is symmetrically connected with two protrusions, each of which is threaded with a locking bolt, and the locking bolt passes through the protrusion and extends into the mounting sleeve.

[0014] By adopting the above technical solution: two protrusions are symmetrically arranged on the outer surface of the mounting sleeve, each protrusion having a threaded hole and a locking bolt installed thereon. The locking bolt passes through the protrusion and extends to the inner wall of the mounting sleeve, used to firmly fix the mounting sleeve to the mounting rod, preventing displacement or detachment during high-speed rotation, thereby improving the safety and reliability of the entire trenching device.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a ditching mechanism and installing it inside the frame, the frame protects the drive unit and other components within the ditching mechanism. When the drive motor is started, its output drives the rotating rod to rotate, which in turn drives the drive bevel gear to rotate synchronously. This causes the transmission bevel gears meshing on their outer surfaces to rotate in opposite directions. The transmission bevel gears are key components of the ditching unit, thereby driving two sets of ditching units to simultaneously ditch the farmland, achieving the goal of improving ditching efficiency and reducing the manpower burden on agricultural workers.

[0016] 2. By setting up a trenching unit, the transmission bevel gear and the drive bevel gear are meshed together to facilitate subsequent meshing and rotation of the trenching body. The length of the locking bolt is adjusted to allow the trenching body to move, thereby adjusting the relative position of the keyway and spline. After adjustment, the locking bolt is tightened to fix the trenching wheel and the mounting rod, achieving the purpose of facilitating quick adjustment of the trenching width and adapting to various trenching needs.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: A trenching machine for agricultural planting includes a mounting frame 1, with an integrally formed machine frame 2 at the front end of the mounting frame 1. A trenching mechanism 3 is provided inside the machine frame 2, and mounting holes are provided at all four corners of the mounting frame 1.

[0023] In this embodiment, the trenching mechanism 3 includes a drive motor 4, which is fixedly installed on the frame 2. The output end of the drive motor 4 is fixedly connected to a rotating rod 5, which is movably connected to the frame 2 via a bearing. One end of the rotating rod 5 is fixedly connected to a drive bevel gear 6, which is located inside the frame 2 and has trenching units 7 connected to both sides. The two trenching units 7 are mounted opposite each other on the frame 2. The trenching unit 7 includes a mounting rod 71, which is rotatably connected to the frame 2 via a bearing. One end of the mounting rod 71 is fixedly connected to a transmission bevel gear 72, which meshes with the drive bevel gear 6. The upper and lower sides of the outer surface of the mounting rod 71 are integrally formed with splines 73, and the trenching body 74 is detachably mounted on the mounting rod 71 via the splines 73.

[0024] The above solution aims to improve overall ditching efficiency and reduce the manpower burden on agricultural workers. The ditching mechanism 3 is installed inside the frame 2, and the frame 2 protects the drive unit and other components inside the ditching mechanism 3. The drive motor 4 is started, and the output end of the drive motor 4 drives the rotating rod 5 to rotate. The rotating rod 5 drives the drive bevel gear 6 to rotate synchronously, which in turn causes the transmission bevel gear 72, which is meshed on its outer surface, to rotate in opposite directions. The transmission bevel gear 72 is a key component of the ditching unit 7, thereby driving two sets of ditching units 7 to simultaneously ditch the farmland.

[0025] In this embodiment, the trenching body 74 includes a mounting sleeve 741, a trenching wheel 743 is fixedly connected to the middle of the mounting sleeve 741, and a keyway 742 is provided inside the mounting sleeve 741 to cooperate with the spline 73. The mounting sleeve 741 is slidably connected to the mounting rod 71 through the keyway 742. The length of the spline 73 is twice the length of the mounting sleeve 741. The trenching wheel 743 and the mounting sleeve 741 are coaxially arranged and integrally formed. Two protrusions 7411 are symmetrically connected to the outer surface of the mounting sleeve 741. Each protrusion 7411 is threaded with a locking bolt 7412, and the locking bolt 7412 passes through the protrusion 7411 and extends into the mounting sleeve 741.

[0026] The above solution allows for the following: During trenching operations, the trench width needs to be adjusted. At this time, the transmission bevel gear 72 and the drive bevel gear 6 are meshed together to facilitate subsequent meshing and rotation of the trenching body 74. The length of the locking bolt 7412 is adjusted to allow the trenching body 74 to move, thereby adjusting the relative position of the keyway 742 and the spline 73. After adjustment, the locking bolt 7412 is tightened to fix the trenching wheel 743 to the mounting rod 71, adapting to various trenching needs.

[0027] It should be noted that this utility model is a ditching machine for agricultural planting. During use, the ditching machine is first mounted on the front of the agricultural machinery using the mounting frame 1, and runs synchronously with the agricultural machinery. To improve overall ditching efficiency and reduce the manpower burden on agricultural personnel, the ditching mechanism 3 is installed inside the frame 2. The frame 2 protects the drive unit and other components within the ditching mechanism 3. The drive motor 4 is started, and its output drives the rotating rod 5 to rotate. The rotating rod 5 drives the drive bevel gear 6 to rotate synchronously, which in turn causes the transmission bevel gear 72, which meshes with the outer surface of the gear, to rotate in opposite directions, thus transmitting power. The bevel gear 72 is a key component of the ditching unit 7, which drives two sets of ditching units 7 to simultaneously ditch the farmland. During the ditching operation, the ditch width needs to be adjusted. At this time, the transmission bevel gear 72 and the drive bevel gear 6 are meshed together to facilitate subsequent meshing and rotation of the ditching body 74. The length of the locking bolt 7412 is adjusted to make the ditching body 74 movable, thereby adjusting the relative position of the keyway 742 and the spline 73. After the adjustment is completed, the locking bolt 7412 is tightened to fix the ditching wheel 743 to the mounting rod 71, which can adapt to various ditching needs.
