Description

Technical Field

[0001] This utility model relates to the technical field of double-disc furrow openers, and in particular to a double-disc furrow opener for an anti-tangling no-till seeder. Background Technology

[0002] The double-disc furrow opener of the anti-tangle no-till seeder belongs to the field of agricultural seeding machinery technology. It is mainly used in the furrowing process of no-till seeding operations. No-till seeding technology, as a conservation tillage method, can effectively reduce soil erosion and water loss and improve soil fertility. As the core component of the seeder, the double-disc furrow opener functions to cut seed furrows on uncultivated land and create favorable conditions for seeds to enter the soil. With the development of agricultural mechanization and intelligence, higher requirements have been placed on the reliability, adaptability and anti-clogging ability of the furrow opener. The development of efficient and reliable double-disc furrow openers is of great significance for improving seeding quality and operation efficiency.

[0003] In the prior art, the double-disc trencher usually consists of a pair of inclined and symmetrically arranged discs, a connecting shaft, a support, and a soil scraping device. Its technical principle is to use the two discs to roll in the soil and rely on their cutting edges to cut the soil to form a planting trench. The discs are usually mounted on the shaft by bearings to ensure their rotational flexibility. Some designs will install fixed scraper plates on the side of the discs to remove the soil adhering to the surface of the discs.

[0004] However, existing dual-disc furrow openers generally have a significant problem in actual operation: in wet or weedy field conditions, the surface of the disc easily sticks to soil and gets entangled with weeds when rotating to open furrows. Traditional scrapers, lacking an effective adaptive pressure adjustment mechanism, often have situations where they are too tightly attached to the disc surface, aggravating wear, or too loosely attached, resulting in incomplete cleaning. This leads to increased disc rotation resistance, uneven furrow depth, seriously affecting the quality and efficiency of sowing operations, and shortening the service life of the disc. To address this, a dual-disc furrow opener for an anti-entanglement no-till seeder is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a double-disc furrow opener for an anti-tangling no-till seeder, which aims to improve the problems in the prior art where the scraper blade often adheres too tightly to the disc surface, aggravating wear, or adheres too loosely, resulting in incomplete cleaning, due to the lack of an effective adaptive clamping adjustment mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A double-disc furrow opener for an anti-tangle no-till seeder includes a connecting shaft, a connecting column fixedly connected to the top of the connecting shaft, a connecting piece fixedly connected to the side wall of the connecting column, a connecting plate provided on the side wall of the connecting piece, a baffle fixedly connected to the outer wall of the connecting column, a first disc fixedly connected to the outer wall of the connecting shaft, a second disc rotatably connected to the outer wall of the connecting shaft, and a fixing plate rotatably connected to the outer wall of the connecting column, with a scraping component provided inside the fixing plate; The scraping assembly includes a scraper and a spiral spring. The scraper is rotatably connected to the outer wall of the fixed plate, and the spiral spring is sleeved on the outer wall of the fixed plate. One end of the spiral spring is fixedly connected to the side wall of the scraper, and the other end of the spiral spring is fixedly connected to the outer wall of the fixed plate. A connecting assembly is provided between the connecting member and the connecting plate.

[0007] As a further description of the above technical solution: The connecting assembly includes hollow columns, all of which are slidably connected to the inner wall of the connector and the connecting plate, and the connector is in contact with the connecting plate.

[0008] As a further description of the above technical solution: A support plate is fixedly connected to the outer wall of the hollow column, and a pull frame is fixedly connected to the side wall of the support plate.

[0009] As a further description of the above technical solution: A rotating ring is threaded onto the outer wall of the hollow column, and a lever is fixedly connected to the outer wall of the rotating ring.

[0010] As a further description of the above technical solution: The hollow column is rotatably connected to a rotating rod, and the hollow column is slidably connected to a sliding column.

[0011] As a further description of the above technical solution: The bottom of the sliding column is in contact with the outer wall of the rotating rod, and a pressing column is fixedly connected to the bottom of the sliding column.

[0012] As a further description of the above technical solution: The first pressing column is slidably connected inside the hollow column, and the bottom of the first pressing column is fixedly connected to the second pressing column, which is slidably connected inside the hollow column.

[0013] As a further description of the above technical solution: A spring is fitted on the outer wall of the pressing column. One end of the spring is fixedly connected to one side wall of the pressing column, and the other end of the spring is in contact with the inner wall of the hollow column.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a fixed plate drives a scraper to adhere to the side walls of disc one and disc two. Then, the elasticity of a spiral spring drives the scraper to adaptively adjust the adhesion force with the side walls of the discs, avoiding excessive pressure between the scraper and the discs, which could cause wear, or loose adhesion, which could lead to incomplete cleaning. As a result, during the rotation of disc one and disc two, the soil and weeds attached to their side walls can be continuously scraped and cleaned by the scraper, thereby maintaining the cleanliness of the disc surface and ensuring normal rotation of the discs. This solves the problem of uneven trenching depth and increased operating resistance caused by soil and weeds attached to the discs in traditional double-disc trenchers, and improves the operating stability of the trencher and the service life of the discs.

[0015] 2. In this utility model, by pulling the frame, the support plate and hollow column are slid into the fitting gap between the connector and the connecting plate. Then, by using a lever, the rotating ring is driven to rotate and move along the outer wall of the hollow column. The rotating rod rotates and contacts the outer wall of the connecting plate, compressing the elastic spring to form a stable locking force, thereby making the connector and the connecting plate firmly connected. This enables the manual and quick installation and disassembly of the furrow opener and the seeder, thus achieving the effect of simplifying the installation and disassembly process without the need for additional tools. It solves the problems of cumbersome, time-consuming and labor-intensive installation and disassembly of traditional furrow openers, which affect the efficiency of sowing operations, and improves the ease of installation and operation preparation efficiency of the furrow opener.

One end of the helical spring 10 is fixedly connected to the side wall of the scraper 9 to transmit elastic force, and the other end of the helical spring 10 is fixedly connected to the outer wall of the fixed plate 8 to provide reaction force. A connecting assembly is provided between the connector 3 and the connecting plate 4. The connecting assembly is used to achieve quick assembly and disassembly and lock the connection.

[0020] Reference Figure 1 - Figure 5The connecting assembly includes a hollow column 12, which serves as the mounting housing for connecting the guide rod and the internal mechanism. The hollow column 12 is slidably connected to the inner wall of the connecting piece 3 and the connecting plate 4 for axial positioning. The connecting piece 3 and the connecting plate 4 are fitted together to form a mating plane. A support plate 11 is fixedly connected to the outer wall of the hollow column 12, transmitting operating force and supporting the pulling mechanism. A pulling frame 18 is fixedly connected to the side wall of the support plate 11, facilitating manual operation to pull the entire connecting assembly. A rotating ring 19 is threadedly connected to the outer wall of the hollow column 12, converting rotational motion into axial displacement. A lever 20 is fixedly connected to the outer wall of the rotating ring 19, allowing for manual force application to drive the rotating ring 19 to rotate. A rotating rod 14 is rotatably connected inside the hollow column 12, rotating under pressure to achieve locking. A sliding mechanism is also slidably connected inside the hollow column 12. The moving column 13 and sliding column 13 are used to transmit axial pressure and trigger the rotation rod 14.

[0021] Working principle: First, the fixed plate 8 drives the scraper 9 to adhere to the side walls of disc 6 and disc 7. Then, the elasticity of the helical spring 10 drives the scraper 9 to adaptively adjust the adhesion force with the side walls of the discs, avoiding excessive pressure between the scraper 9 and the discs, which could cause wear, or loose adhesion, which could lead to incomplete cleaning. As discs 6 and 7 rotate around the connecting shaft 1, the scraper 9 continuously scrapes and cleans the soil and weeds attached to their side walls, keeping the disc surface clean and ensuring normal rotation of the discs. This solves the problem caused by soil and weeds adhering to the discs in traditional double-disc furrow openers. When installing the furrow opener and the seeder, the frame 18 is pulled... The moving support plate 11 and the hollow column 12 slide into the fitting gap between the connector 3 and the connecting plate 4. Then, the lever 20 drives the rotating ring 19 to rotate and move along the outer wall of the hollow column 12. During the rotation of the rotating ring 19, the rotating rod 14 inside the hollow column 12 rotates. After the rotating rod 14 rotates, it contacts the outer wall of the connecting plate 4. At the same time, the pressing column 16 is subjected to force, which drives the pressing column 15 to compress the elastic spring 17, forming a stable locking force. This makes the connector 3 and the connecting plate 4 firmly connected, realizing the manual quick installation and disassembly of the furrow opener and the seeder without the need for additional tools, simplifying the installation and disassembly process and solving the problem of cumbersome installation and disassembly of traditional furrow openers.
