Description

Technical Field

[0001] The utility model belongs to the technical field of winter wheat planting, in particular to a furrowing seeder. Background Art

[0002] A furrow seeder is an important agricultural tool used for planting crops in modern agricultural production. It helps improve production efficiency and crop quality by digging furrows and placing seeds directly into the soil.

[0003] The prior art discloses a furrowing, sowing and soil covering device (CN221010689U), comprising a main body support, a furrowing plow assembly, a sowing assembly and a soil covering assembly; walking wheels are respectively installed on both sides of the front and rear ends of the main body support, and the furrowing plow assembly, the sowing assembly and the soil covering assembly are sequentially installed at the bottom of the main body support from front to rear; the sowing assembly comprises a seed storage hopper, a seed discharge hopper, a sowing tube, a rotating roller, a rotating shaft and a driven pulley, the rotating roller is horizontally installed in the seed storage hopper through the rotating shaft, the driven pulley is fixedly installed at one end of the rotating shaft, at least one discharge groove is provided on the circumferential surface of the rotating roller, a conical seed upper hopper is provided on the top of the rotating roller, the bottom of the seed upper hopper is in close contact with the circumferential surface of the rotating roller, a driving pulley is installed on the walking wheel at the rear end of the main body support, and a driving belt is connected between the driving pulley and the driven pulley.

[0004] After searching, it was found that the seed storage hopper and the nutrient soil storage hopper in the existing technology could not be released in the order of sequence when in use, which resulted in the position of the nutrient soil covering being inconsistent with the position of the seeds, resulting in insufficient seed fertilizer, thus affecting seed growth. Furthermore, the number of seeds that the rotating roller in the sowing component can carry is limited, which leads to limitations in sowing. When faced with larger-particle seeds, it is often impossible to sow with a higher survival rate, thus affecting the use of seeds in the later stage. Finally, considering that some soils have larger stones and harder bottom surfaces, it is difficult for the existing technology to completely open furrows using only a furrow opener, which not only affects the planting depth of the seeds, but also seriously affects the coverage rate of the soil on the seeds, which is not conducive to creating good seed production conditions.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0030] Specifically, the device is provided with a rear running wheel 14 in conjunction with the intermittent spreading structure, and the cam 15 drives the pushing frame 18. When the pushing frame 18 moves, the upper baffle 19 and the lower baffle 20 slide in different positions of the support tube 27 respectively, thereby changing the feeding mode in the feeding through hole to an intermittent feeding mode. At this time, the feeding position of the nutrient soil follows the seeds immediately. This not only ensures that the feeding positions of the two are at the same frequency, but also ensures that the amount of seeds and nutrient soil is synchronized, thereby ensuring the production of seeds. There is no need to consider the number of seeds falling, ensuring a certain amount of sowing within a certain time, thereby improving the sowing survival rate of seeds, thereby ensuring the germination of seeds in the later stage. By providing a front running wheel 21 in conjunction with the processing structure, the soil is loosened by the plowing wheel 22, and after the furrowing is carried out by the furrowing block 23 and the intermittent spreading structure is used for sowing and spreading, the soil is covered by the covering wheel 12, so that the seeds can be effectively sown at a suitable depth, ensuring the coverage rate of the soil on the seeds, thereby creating good production conditions for the seeds.

[0031] like Figure 1 and Figure 4 As shown, the front end of the walking frame 10 is rotatably provided with a front running wheel 21. The front running wheel 21 has the same shape as the rear running wheel 14, and both are composed of two pulleys and a fixed shaft. No less than five sets of plowing wheels 22 are fixedly connected to the curved surface of the fixed shaft of the front running wheel 21.

The fixed bracket 11 consists of two square plates and a connecting shaft. No less than five sets of covering wheels 12 are rotatably arranged on the connecting shaft. The covering wheels 12 include two symmetrically arranged conical thin plates. The covering wheels 12 are arranged corresponding to the ditching blocks 23.

[0032] The working principle is as follows: when the front wheel 21 rolls, the plowing wheel 22 connected to the front wheel 21 will roll synchronously, and the triangular thorn teeth will be used to loosen the ground soil. At the same time, when the traveling bracket 10 moves, the triangular block of the trenching block 23 will follow the position loosened by the plowing wheel 22 to dig trenches. Synchronously, the intermittent spreading structure will spread seeds and nutrient soil in the trench, and the last covering wheel will roll along both sides of the trench to cover the soil and bury the seeds.

[0033] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the interior of the walking frame 10 is provided with an active cavity 28 and a through hole 26, the active cavity 28 is communicated with the through hole 26, the rear walking wheel 14 is rotatably arranged in the through hole 26, the through hole 26 is arranged above the active cavity 28, and no less than five groups of cams 15 are fixedly connected to the curved surface of the fixed axis of the rear walking wheel 14, and the cams 15 are movable and penetrate in the active cavity 28; Figure 4 As shown, the support tube 27 is a Y-shaped block, and the support tube 27 has a seed storage cavity 24 and a fertilizer storage cavity 25 symmetrically opened inside. The seed storage cavity 24 and the fertilizer storage cavity 25 have the same shape. The seed storage cavity 24 and the fertilizer storage cavity 25 are composed of five feeding through holes and a trapezoidal cavity; Figure 2 、 Figure 3 and Figure 4 As shown, a slide groove 16 is provided on one side of the cam 15, and a push frame 18 is fixedly connected to a slide column 17 on one side close to the cam 15. The slide column 17 slides in the slide groove 16. The push frame 18 is a T-shaped frame. The upper baffle 19 is fixedly provided on one side of the top surface of the push frame 18, and the lower baffle 20 is provided on the other side of the bottom surface of the push frame 18.

The sliding groove 13 push frame 18, the upper baffle 19 and the lower baffle 20 all slide in the sliding groove 13.

[0034] The specific implementation is as follows. First, in the initial state, the upper baffle 19 and the lower baffle 20 both block the seed storage chamber 24 and the fertilizer storage chamber 25, and the upper baffle 19 and the lower baffle 20 are located in the middle of the sliding groove 13. When the front wheel 21 rolls and moves, the plowing wheel 22 connected to the front wheel 21 will roll synchronously, and the triangular thorn teeth will be used to loosen the ground soil. At the same time, when the walking bracket 10 moves, the triangular block of the ditching block 23 will follow the position of the plowing wheel 22 after loosening the soil to dig trenches. Synchronously, the rear wheel 14 rolls, and the cam 15 rolls in the active chamber 28. There is a square strip groove communicating between the sliding groove 13 and the through hole 26.

The seed storage chamber 24 and the fertilizer storage chamber 25 are both connected to the sliding groove 13. During the sliding process, when the upper baffle 19 is away from the discharge hole of the seed storage chamber 24, the lower baffle 20 blocks the discharge hole of the seed storage chamber 24. At this time, the nutrient soil falls from the discharge hole of the fertilizer storage chamber 25. When the upper baffle 19 blocks the discharge hole of the fertilizer storage chamber 25, the lower baffle 20 is away from the discharge hole of the fertilizer storage chamber 25, and the seeds are able to fall from the discharge hole of the seed storage chamber 24. The last covering wheel rolls along both sides of the groove to cover the soil and bury the seeds.
