Description
Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seed drill with a ditching and soil covering device. Background Art
[0002] As early as the Warring States Period, the primitive seeding machinery, the single-legged plow, appeared. It was the earliest prototype of the seeding machine, which had the functions of furrowing and sowing. However, the efficiency of this seeding machine was still limited, and it required human or animal power to pull. Over time, the seeding machine technology was gradually improved and perfected. By the Han Dynasty, China had promoted the use of the plow, which was the earliest seeding machine in the world. It was not only capable of furrowing and sowing, but also had the function of covering the soil, thereby improving the efficiency and quality of sowing. At the same time, people in the Han Dynasty also used irrigation and fertilization technology to improve the yield and quality of crops. After entering modern times, with the rise of the industrial revolution and the advancement of science and technology, the development of seeding machines entered a new stage. From the late 18th century to the early 19th century, the earliest seeding machines began to appear. These seeding machines were mainly manually operated by people to evenly spread seeds on the soil. However, the efficiency and accuracy of these manual seeders were still low. By the mid-19th century, with the application of mechanical principles and the development of the industrial revolution, the first batch of seeding machines based on mechanical principles appeared. These mechanical seeding machines can improve the speed and accuracy of sowing and reduce the demand for labor. Subsequently, electric drive systems were also introduced into seeders, making the use of seeders more convenient and efficient. After entering the 20th century, seeder technology continued to be innovated and developed. With the advancement of science and technology, seeders have gradually achieved automation and intelligence. Modern seeders not only have functions such as furrowing, sowing, and covering, but can also accurately control the seeding amount and sowing depth according to the type of crop and sowing requirements to achieve precise sowing. At the same time, some advanced seeders are also equipped with intelligent control systems that can monitor and adjust sowing parameters in real time to improve sowing effects and crop yields.
[0003] Traditional seed drills can only open one width and depth of seeding furrows during the furrowing process. For small seeds, the seeding furrow is too large, and the seeds are buried too deep after covering, which affects the germination rate. For large seeds, the seeding furrow is too small, and the seeds are too shallow after covering, which also affects the germination rate. It is impossible to adjust the width and depth of the seeding furrow according to the size and type of seeds to be sown. Utility Model Content

After adjusting to the appropriate position, the bolts are tightened to adjust the distance between the two sowing furrows.
[0033] A front furrowing member 21 is provided at the bottom of the front lifting rod 16. The front furrowing member 21 is a parallelogram when viewed from the side. The whole is formed by bending an iron sheet and is fixedly installed at the bottom of the front lifting rod 16. A front receiving tube 19 is provided behind the front furrowing member 21. The front receiving tube 19 can receive seeds discharged from the front row seed conduit 20 and guide them to fall into the sowing furrow. The front row seed conduit 20 is provided on the front receiving tube 19. The upper end of the front row seed conduit 20 is connected to the seed box 30. The front row seed conduit 20 can receive seeds dropped from the seed box 30 and guide them to the front receiving tube 19.
[0034] A rear trenching member 28 is provided at the bottom of the rear lifting rod 23. The rear trenching member 28 is a triangular structure when viewed from the side. It is also formed by bending an iron sheet and is fixedly installed at the bottom of the rear lifting rod 23. A rear receiving tube 26 is provided behind the rear trenching member 28. A rear row seed conduit 27 is provided on the rear receiving tube 26. The upper end of the rear row seed conduit 27 is connected to the seed box 30. The rear receiving tube 26 and the rear row seed conduit 27 have the same function as the front receiving tube 19 and the front row seed conduit 20, that is, they all receive seeds dropped from the seed box 30 and guide them to fall into the corresponding sowing groove to ensure the accuracy of seed falling.
[0035] The width of the front furrowing member 21 is greater than that of the rear furrowing member 28. The width of the front furrowing member 21 is greater than that of the rear furrowing member 28 because the width and depth of the sowing furrow are generally greater when sowing large seeds, so a front furrowing member 21 with a greater width should be selected, and its height should be appropriately lowered so that it can open a deeper and wider sowing furrow. In addition, when the front furrowing member 21 is selected, it is necessary to cooperate with the soil cover 29 installed on the rear furrowing member 28. Since its width is greater than that of the rear furrowing member 28, when the front furrowing member 21 and the rear furrowing member 28 are at the same height, the rear furrowing member 28 will not affect the sowing furrow that has been opened by the front furrowing member 21, but the soil cover 29 on the rear furrowing member 28 will still perform soil covering operations.
[0036] A soil cover 29 is also provided at the rear of the rear receiving tube 26. The upper end of the soil cover 29 is rotatably mounted on the upper end of the rear receiving tube 26. The middle part of the soil cover 29 is connected to the bottom of the rear receiving tube 26 by a spring 31. The soil cover 29 is formed by folding a steel plate. When performing soil covering operations, the bottom of the soil cover 29 will contact the soil, and in the process of moving forward, the soil opened in the furrow will be gathered to the middle of the sowing furrow. This gathering requires a certain amount of force, so the spring 31 provides a certain amount of force for the soil cover 29, so that it can cover the soil better. In addition, through the rotational connection between the soil cover 29 and the rear receiving tube 26, the soil cover 29 can have a certain swing amplitude, and can pass smoothly when encountering small stones or obstacles during the process of moving, thereby increasing the fluency of sowing.
[0037] Working principle: Before sowing, first determine whether to sow large or small seeds, the required sowing depth, and the distance between two rows of seeds, so as to choose whether to use the front furrow opener 15 or the rear furrow opener 22 to open the furrow. When large seeds need to be sown, the two front furrow openers 21 are adjusted to a suitable position through the front middle connecting member 17, the front connecting slider 18 and the bolts, and the two rear furrow openers 28 are also adjusted to the same position as the front opening member. Since the size of the front furrow opener 21 is larger than the rear furrow opener 28, the rear furrow opener 28 will not affect the furrow opened by the front furrow opener 21 at this time, but the soil cover 29 on the rear furrow opener 28 will still cover the furrow opened by the front furrow opener 21 with soil. When small seeds are to be sown, the two front furrowing members 21 are lifted by the front lifting rod 16 to keep them away from the land where furrowing is to be done, and then the two rear furrowing members 28 are adjusted to a suitable position, and the rear furrowing members 28 will open a sowing furrow suitable for small seeds, and the soil coverer 29 of the rear furrowing member 28 will cover the opened furrow with soil. When sowing, the seeds to be sown are placed in the seed box 30, and then the handrail 2 and the motor 8 can be used to push the seeder forward to achieve furrowing and soil covering.
