Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a contour-covering and soil-pressing device for a trough-type Panax notoginseng precision seeder. Background Art
[0002] The agronomic requirements for trough-type Panax notoginseng seeding are a small row spacing of 50mm, a sowing depth of 10mm, and shallow sowing depth precision sowing, which has high requirements for the soil covering and pressing of the Panax notoginseng seeder (26-28 rows of seed furrows need to be opened in a 1.5m wide seedling trough, with the centers of adjacent seed furrows 50mm apart and the soil covering thickness of 10mm). However, there are two difficulties in the soil covering process. First, the seeds will undergo secondary displacement due to soil disturbance during soil covering, and the soil covering thickness is shallow and has high consistency requirements. Second, the pressing wheel will produce soil mounding and unstable pressing pressure during the pressing process. These two problems have become technical difficulties for Panax notoginseng precision sowing.
[0003] In view of the current situation of trough-type Panax notoginseng seedling cultivation, during the soil covering operation of Panax notoginseng precision seeder, the seeds move in the ridge furrow (seed furrow) and produce secondary displacement, which changes the row spacing and sowing depth. At the same time, the uneven soil surface makes it difficult to ensure the consistency of soil covering thickness. Based on this, a contour covering mechanism is designed to reduce the seed displacement caused by soil disturbance and maintain a high consistency of soil covering thickness, which plays an important role in the mechanization development of Panax notoginseng.
[0004] Suppression is an important link in the process of precision seeding, which has a great impact on the actual spacing, sowing depth, germination, seedling quality, yield, etc. of seeds. Too low a pressure will not retain moisture, while too much pressure will make the soil too compact, which is not conducive to seed germination and high-quality seedling cultivation. The center of gravity of the pressure wheel is directly below the wheel axle, and the inertia of rotation is small. The pressure wheel is prone to instantaneous rotation failure, resulting in dragging or soil mounding, which affects the uniformity of seed spacing and the consistency of sowing depth and is not conducive to the cultivation of high-quality seedlings. Therefore, it is necessary to control the optimal range of the pressure and increase the rotation inertia of the pressure wheel, so that the pressure mechanism can achieve contoured pressure under the optimal value of the compaction requirement to avoid soil mounding. For this reason, the present invention designs a contoured soil covering and suppression device for a trough-type Panax notoginseng precision seeder. Summary of the invention
[0005] The purpose of the present invention is to provide a trough-type Panax notoginseng precision seeder contour-covering and suppressing device, which can ensure a small seed displacement, high consistency in soil covering thickness and soil compaction, is beneficial to Panax notoginseng seed germination and high-quality seedling cultivation, and solves the key technology of Panax notoginseng factory-based trough-type seedling cultivation.

[0013] The working process of the present invention is as follows:
[0014] The structural design of the present invention is mainly based on the trough type Panax notoginseng seedling precision seeder. According to the problems existing in the previous soil covering and pressing process, the entire soil covering and pressing device is designed in sections, and the soil covering and pressing are separated to meet the special agronomic requirements of Panax notoginseng seedling precision sowing. The whole article introduces a section of soil covering and pressing device (its width is 250mm, the spacing between two adjacent soil covering devices is 50mm, and the arrangement is as follows: Figure 8 ), the working principles of the other four sections are the same.
[0015] When the soil covering and compaction operation is carried out, the motor provides power to drive the unit forward. Under the action of the unit, the upper shaft component B drives the soil covering component F to break the ridges with the two lower sides of the shovel tip 37 (ridge height 21mm, ridge bottom width 30mm, and ridge end surface is in the shape of an isosceles triangle), so that the ridge body soil slides from both sides of the ridge ditch to the center of the ridge ditch to cover the Panax notoginseng seeds, which can reduce the secondary displacement of the seeds. At the same time, the ridge soil covered with the seeds is subjected to the downward pressure of the two lower sides of the shovel tip 37 on the ground, which compacts the soil and stabilizes the seeds under the soil; the thickness of the soil covering is controllable, and the hole group III12 of the vertical plate I11 and the hole group VII25 of the upper plate III24 are first adjusted to I1 through bolts to adapt to the height of the soil trough step and the soil surface The uneven soil surface is floated up and down by the profiling structure component ID and the profiling structure component ⅡE under the combined action of the spring combined elastic force, the gravity of the soil covering device and the supporting force of the soil on the two lower sides of the shovel tip 37 to realize longitudinal profiling and soil covering; at the same time, in order to avoid the situation that the entire soil covering device is only one section and cannot adapt to the unevenness of the soil in the width direction of the seedling trough (the direction perpendicular to the forward direction of the seeder), the soil covering device is divided into 6 sections, and each section of the soil covering mechanism corresponds to the uneven flatness of the soil surface in the seedling trough. When the soil covering thickness is kept stable during longitudinal profiling, each section of the soil covering mechanism independently completes the profiling and soil covering of each section in the width direction of the seedling trough, that is, realizes lateral profiling.
[0016] When the controllable soil covering thickness is completed, the hollow pressing wheel mechanism completes the pressing while rolling forward. The pressing wheel assembly G adjusts its own gravity by adding or reducing the counterweight plate 45 on the counterweight assembly J to compact the soil, explores the pressing wheel gravity corresponding to the optimal compactness, and adjusts the pressing wheel to this gravity to keep the pressing force stable. When adding or reducing the counterweight plate on the counterweight assembly J, the countersunk screw 47 is first rotated inward along the radial direction of the pressing wheel, and then the base 46 and the countersunk screw 47 are moved outward together to add the counterweight plate 45 or the countersunk screw 47 is rotated outward and the base is reduced inward to complete the addition or reduction of the counterweight plate 45; during the pressing process, each section of the pressing wheel can float up and down with the soil surface to achieve longitudinal profiling; when the soil surface is uneven in the width direction of the seedling trough (the direction perpendicular to the forward direction of the seeder), each section of the pressing wheel is raised or sunken with the soil, and independently moves up or down to achieve lateral profiling.
[0017] The beneficial effects of the present invention are as follows: the present invention is aimed at the special sowing agronomy of Panax notoginseng seedlings, and adopts two mechanisms of covering and suppressing. The spatial structure of the present invention is relatively simple, maintenance is convenient, and practicality is strong. During the covering process, the covering device breaks the soil of the ridge body under the action of the gravity of the covering mechanism and the soil support force to achieve the purpose of covering the soil. The profiling structure component ID and the profiling structure component IIE are used to cover the soil according to the soil surface to ensure the consistency of the covering thickness, and provide good seed layer depth conditions for later seed germination and high-quality seedling cultivation; the covering method is that the ridge body soil on both sides of the ridge ditch slides to the center of the ridge ditch, which is conducive to covering the seeds on the bottom of the ditch and reducing the secondary displacement of the seeds, thereby ensuring the uniformity of the seed spacing; the consumable part, the covering device component F, can be replaced by the shovel handle 38, which is easy to maintain.
[0018] In order to solve the problem of dragging or mounding caused by instantaneous failure of the pressing wheel during compaction, which affects the uniformity of grain spacing and consistency of sowing depth, the present invention designs the pressing wheel as a hollow wheel body, and designs the gravity of the pressing wheel on the outer ring of the pressing wheel through a structural design, thereby increasing the inertia of rotation and solving the mounding problem caused by instantaneous failure of the pressing wheel, that is, avoiding the dragging of the pressing wheel. At the same time, the pressing wheel is designed as an adjustable counterweight component J, which is convenient for cooperating with different compaction requirements and increasing the roughness of the pressing wheel surface.
[0019] Through the combination of the above two methods, the problems of poor sowing depth consistency and grain spacing uniformity caused by uneven soil covering, secondary displacement of seeds during soil covering and soil mounding caused by the pressing wheel during Panax notoginseng seedling sowing can be effectively solved, providing basic guarantees for the later germination of Panax notoginseng seeds and the cultivation of high-quality seedlings, and promoting the development of Panax notoginseng factory-based trough seedling precision sowing technology.
