Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment, in particular to a sowing and covering device. Background Art

[0002] In the traditional corn planting process, soil covering after sowing is mostly done manually or by simple machines. Most simple machines only use two soil covering wheels to squeeze the soil on both sides of the seed furrow to cover the corn seeds, and the uniformity and suitability of the soil covering cannot achieve a uniform effect. If the soil covering is too thin, the seeds are easily affected by the external environment, such as wind erosion, temperature fluctuations, etc., which will affect the germination rate; if the soil covering is too thick, it may cause uneven emergence of seedlings, or even the death of seedlings due to their inability to break through the soil. In addition, unreasonable soil structure will also affect the soil's water retention capacity and air permeability, thereby affecting the growth and yield of crops.

[0003] In order to solve the above problems, the agricultural machinery field has been exploring more efficient and accurate seeding and covering solutions. Although some existing covering devices have improved the operating efficiency to a certain extent, they still have shortcomings such as inconvenient adjustment, poor adaptability, and complex structure. Therefore, it has become an urgent need for the industry to develop a seeding and covering device that can effectively improve the soil structure and improve the contact quality between seeds and soil, while being easy to operate and highly adaptable.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0029] See also Figure 1-7 As shown, the utility model is a sowing soil covering device, including a frame 1 and a soil covering component 2, a scraping component 4 and a pressing component 5 installed on the frame 1. The soil covering component 2 covers the planting ditch with soil, the scraping component 4 trims the soil covering layer, and the pressing component 5 presses the trimmed soil covering layer to achieve trimming and pressing after soil covering. The soil covering component 2 can ensure that the seeds are covered with soil of appropriate thickness by covering the planting ditch with soil, which helps to protect the seeds from the influence of the external environment, such as wind erosion and temperature fluctuations. The scraping component 4 further trims the soil covering layer to make the soil surface flat, which is not only conducive to the uniform distribution of moisture in the soil, but also reduces moisture evaporation and keeps the soil moist. The pressing component 5 presses the trimmed soil covering layer to make the contact between the seeds and the soil closer, which helps the seeds better absorb moisture and nutrients in the soil, thereby improving the emergence rate. Combination of soil covering and pressing: Suppression after soil covering can reduce the pores in the soil and reduce the possibility of water loss through evaporation, thereby maintaining soil moisture and providing a stable water source for the growth of corn. Under drought conditions, the combined effect of soil covering and compaction is particularly important. It can help the soil retain water and moisture, improve corn's drought resistance, and ensure that corn can grow normally under adverse climatic conditions.

[0030] The frame 1 includes a vertical pole 11. Two rectangular inserts 12 for installing the soil covering component 2 are symmetrically fixed to the opposite side walls at the lower end of the vertical pole 11. The outer side wall of the rectangular insert 12 is provided with a first threaded hole 13. The soil covering component 2 is inserted into the two rectangular inserts 12 and fixed by two bolts 3. Two frame plates 14 are symmetrically fixed to the opposite side walls at the upper end of the vertical pole 11. A rod body 15 extending backward is fixed to the upper end of the vertical pole 11. A first rectangular insert 16 and a second rectangular insert 17 are vertically arranged in the middle and tail of the rod body 15, respectively. The scraping component 4 and the suppression component 5 are respectively inserted and installed in the first rectangular insert 16 and the second rectangular insert 17. The side of the rod body 15 is provided with a second threaded hole 18 and a third threaded hole 19 connected to the first rectangular insert 16 and the second rectangular insert 17, respectively. The second threaded hole 18 is threadedly connected with a first handle bolt 6. The third threaded hole 19 is threadedly connected with a second handle bolt 7.

[0031] Among them, the soil covering component 2 includes a soil covering adjustment frame 21 and two soil covering wheels 22 installed on the soil covering adjustment frame 21. The soil covering adjustment frame 21 includes two symmetrically arranged L-shaped vertical plates 211. The lower ends of the two L-shaped vertical plates 211 are fixedly connected as a whole by two fixing plates 214. The horizontal end of the L-shaped vertical plate 211 is provided with a slope 212 inclined downward. The slope 212 is vertically fixed with a first single-ended threaded shaft 213. The soil covering wheel 22 is installed on the first single-ended threaded shaft 213 and fixed by a first nut. The upper and lower positions of the soil covering component 2 are adjustable, that is, the thickness of the soil covering from both sides to the middle corn planting ditch is adjustable, and the soil covering thickness for planting corn in different soil layer structures is convenient to adjust, and the overall structure is reasonable and simple.

[0032] Among them, the scraping component 4 includes a first rectangular upright pole 41 that cooperates with the inner wall of the first rectangular socket 16. A circular arc plate 42 is fixed to the side of the soil covering component 2 at the lower end of the first rectangular upright pole 41. A circular arc notch 43 is provided at the lower end of the circular arc plate 42. Before scraping and covering the soil, pre-pile the soil in front of the circular arc plate 42 to make up for the problem that the amount of soil in the front section may be insufficient. The circular arc plate 42 of the scraping component 4 scrapes the soil above the seeds after covering the soil, pushes away the excessively deep part, and fills the insufficiently thick part with enough soil. The circular arc notch 43 below it shapes the covering pattern after corn planting, with the middle high and the two sides low, to avoid water accumulation at the roots of corn. The thickness of the covering soil layer of the scraping component 4 is adjustable, which is convenient for adjustment according to different geographical environments.

[0033] Among them, the pressing assembly 5 includes a pressure wheel mounting frame 51 and an arc groove wheel 52. The pressure wheel mounting frame 51 includes a second rectangular vertical rod 511 that cooperates with the inner wall of the second rectangular insertion hole 17. An inverted L-shaped rod 512 is fixed to the lower end of the second rectangular vertical rod 511. A second single-ended threaded shaft 513 is fixed to the side of the L-shaped rod 512 adjacent to the rod body 15. The arc groove wheel 52 is installed on the second single-ended threaded shaft 513 and fixed by a second nut. Adjust the arc groove wheel 52 to put the covering soil in a good pressure state, and then tighten the second handle bolt 7 to fix the pressure wheel mounting frame 51. Pressure effectively increases the contact between corn seeds and soil, which is conducive to germination and rooting.

[0034] The free end of the rod body 15 is tilted downward, and the downward structure is adopted, so that the length of the rectangular upright part of the leveling component 4 and the pressing component 5 can be shortened, and the weight distribution of the rear end of the frame 1 is also reduced. The weight of the overall covering structure is controlled, and the manufacturing cost is also controlled.
