Description

Technical Field

[0001] This utility model relates to the field of tillage aids, and in particular to a tillage aid for scraping and tilling fields. Background Technology

[0002] Currently, with the increasing efforts in farmland irrigation reform in my country, people are paying more attention to arable land technology. Innovating arable land technology and machinery can effectively improve the efficiency and quality of arable land. To improve agricultural efficiency and reduce manual labor, it is necessary to continuously develop agricultural machinery to replace manual labor in arable land cultivation. Therefore, in the process of arable land cultivation, machinery is gradually replacing manual labor.

[0003] The existing farmland scraper has limitations in design. The fixed scraper can only be raised and lowered by the hydraulic rod on the drive device. The height cannot be finely adjusted according to the terrain undulations or the amount of crop residue. It is difficult to meet the needs of different soil types. For example, in sandy soil, it causes dust due to going too deep into the soil, while in compacted land, it leads to a decrease in soil breaking rate due to insufficient cutting.

[0004] To address the aforementioned problems, this utility model proposes a tillage aid for plowing and scraping fields. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a tillage aid for plowing and scraping fields.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tillage aid for plowing and scraping fields, comprising a fixed frame, a connecting rod assembly fixedly disposed on the upper end surface of the fixed frame, the connecting rod assembly being used to connect to the rear trailing bar of a tractor; fixed frames are bolted to both sides of the fixed frame, and arc-shaped scrapers are slidably disposed at the bottom end of the fixed frames; and an adjustment component is disposed on the fixed frames.

[0007] This invention is further configured such that the adjusting component includes an adjusting nut and a screw. The adjusting nut is rotatably mounted on the top of the fixed frame, and the screw is fixedly mounted on the top of the arc-shaped scraper. The screw slides through the fixed frame and extends above it, with the screw and fixed frame in sliding engagement. The screw and adjusting nut are threadedly engaged. This allows for precise adjustment of the arc-shaped scraper height, ensuring consistent tillage depth.

[0008] The present invention is further provided that a rotating ring is fixedly installed on the outer side of the adjusting nut, and the outer ring of the rotating ring is provided with anti-slip texture, which enhances the friction during operation, facilitates the application of force during manual adjustment, and prevents slippage.

[0009] The present invention is further configured such that sliding rods are slidably installed on both bottom ends of the fixed frame, the bottom ends of the sliding rods are fixedly connected to the arc-shaped scraper, the top ends of the sliding rods are fixedly installed with limit plates, and springs are sleeved on the outer sides of the sliding rods. One end of the spring is fixedly connected to the limit plate, and the other end of the spring is fixedly connected to the inner bottom surface of the fixed frame, providing elastic support for the arc-shaped scraper, which can both buffer the impact of operation and maintain the working stability of the scraper.

[0010] The present invention is further configured such that the bottom side of the arc-shaped scraper is uniformly provided with grooves to form a wavy cutting edge, which effectively reduces the resistance when the scraper cuts into the soil and improves the work efficiency.

[0011] The present invention is further configured such that two supports are fixedly installed at the middle position of the upper end face of the fixed frame, and each support is hinged with a connecting rod. The other end of the connecting rod is bolted to a fixing rod, and the bottom end of the fixing rod is fixedly connected to the upper end face of the fixed frame. The other side of the upper end face of the fixed frame is bolted to the fixed frame, forming a stable triangular support, enhancing the overall rigidity, and allowing the fixed frame to adapt to terrain changes within a certain range.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This tillage aid, used for scraping and tilling fields, consists of a rotating ring, adjusting nut, screw, sliding rod, spring, and limiting plate. The rotating ring drives the adjusting nut to rotate, and the threaded engagement causes the screw to move axially, thereby driving the arc-shaped scraper to rise and fall. The sliding engagement between the sliding rod and the fixed frame ensures the vertical movement of the scraper, the spring provides elastic support and cushions impact, and the limiting plate restricts the maximum stroke. For manual fine-tuning, the operator can precisely control the scraper height by rotating the rotating ring. The entire process is smooth and accurate. This manual fine-tuning method has advantages such as simple and reliable structure, high adjustment accuracy, no need for external power, and adaptability to complex field environments. Mechanical self-locking maintains the set position stably, making it particularly suitable for tillage conditions requiring frequent and precise adjustments.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a tillage aid for plowing and scraping fields, including a fixed frame 1, with a connecting rod assembly 2 fixedly mounted on the upper end surface of the fixed frame 1. The connecting rod assembly 2 is used to connect to the rear trailing bar of a tractor. The specific structure of the connecting rod assembly 2 is as follows: Figure 1 The image shows a standard three-point suspension interface, which offers high stability.

[0024] Both sides of the fixed frame 1 are bolted with fixed frames 3. Two supports 12 are fixedly installed at the middle of the upper end face of the fixed frame 1. Each support 12 is hinged with a connecting rod 13. The other end of the connecting rod 13 is bolted to a fixed rod 14. The bottom end of the fixed rod 14 is fixedly connected to the upper end face of the fixed frame 3. The other side of the upper end face of the fixed frame 3 is bolted to the fixed frame 1.

[0025] The bottom of the fixed frame 3 is equipped with an arc-shaped scraper 4 for limiting sliding.

[0026] An adjustment assembly is provided on the fixed frame 3. The adjustment assembly includes an adjusting nut 5 and a screw 6. The adjusting nut 5 is rotatably mounted on the top of the fixed frame 3, and the screw 6 is fixedly mounted on the top of the arc-shaped scraper 4. The screw 6 slides through the fixed frame 3 and extends to the top of the fixed frame 3, and the screw 6 is in sliding engagement with the fixed frame 3; the screw 6 is in threaded engagement with the adjusting nut 5.

[0027] In this embodiment of the utility model: a rotating ring 7 is fixedly installed on the outer side of the adjusting nut 5, and the outer ring of the rotating ring 7 is provided with anti-slip texture.

[0028] In this embodiment of the utility model: sliding rods 8 are slidably installed on both bottom ends of the fixed frame 3. The bottom ends of the sliding rods 8 are fixedly connected to the arc-shaped scraper 4. Limiting plates 10 are fixedly installed on the top ends of the sliding rods 8. Springs 9 are sleeved on the outer side of the sliding rods 8. One end of the spring 9 is fixedly connected to the limiting plate 10, and the other end of the spring 9 is fixedly connected to the inner bottom surface of the fixed frame 3.

[0029] In this embodiment of the invention: the bottom side of the arc-shaped scraper 4 is uniformly provided with grooves 11, forming a wave-like or sawtooth shape to reduce cutting resistance.

[0030] Working principle:

[0031] When the height of the arc-shaped scraper 4 needs to be finely adjusted, the operator can manually rotate the rotating ring 7, utilizing its anti-slip texture to achieve a stable grip and precise force application. The rotational motion of the rotating ring 7 is directly transmitted to the adjusting nut 5, which is fixedly connected to it. Since the adjusting nut 5 is rotatably mounted on the top of the fixed frame 3 through a bearing structure and forms a threaded engagement with the vertically fixed screw 6, the rotational motion of the adjusting nut 5 will be converted into the axial displacement of the screw 6. The lower end of the screw 6 is rigidly connected to the arc-shaped scraper 4, and the upper section forms a guiding constraint with the sliding engagement hole of the fixed frame 3, ensuring that the screw 6 can only move smoothly in the vertical direction, thereby precisely driving the arc-shaped scraper 4 to adjust its height. During this process, the sliding rods 8, symmetrically distributed on both sides of the fixed frame 3, are fixedly connected to the arc-shaped scraper 4 at their bottom ends. As the slide bar 8 moves, the sliding pair between it and the fixed frame 3 further restricts the displacement trajectory of the arc-shaped scraper 4, preventing horizontal swaying. Simultaneously, the spring 9, sleeved on the outside of the slide bar 8, is always in a pre-compressed state. Its lower end is fixedly connected to the inner bottom surface of the fixed frame 3, and its upper end is in close contact with the limiting plate 10. The elastic restoring force of the spring 9 provides dynamic support for the arc-shaped scraper 4, buffering the impact load during operation and eliminating the gap in the threaded pair after height adjustment. The limiting plate 10 is fixedly connected to the top of the slide bar 8, serving as both the bearing surface of the spring 9 and limiting the maximum stroke of the slide bar 8 through its cooperation with the inner wall of the fixed frame 3, forming double mechanical protection. Finally, by adjusting the self-locking characteristics of the threads of the nut 5 and the screw 6, the arc-shaped scraper 4 is stably maintained at the set height, achieving precise control of the tillage depth. This linkage mechanism, through the synergistic effect of threaded transmission and elastic support, ensures adjustment accuracy while also being easy to operate and reliable in operation.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
