Description

Technical Field

[0001] The invention belongs to the technical field of conservation tillage planting, and in particular relates to a conservation tillage unequal row spacing and density planting mode and a matching device. Background Art

[0002] my country's corn planting history is only about 500 years old, but the area of ​​corn planting and planting technology have developed rapidly. In the past, due to the imperfections of fertilizer technology, seed cultivation and farming technology, the corn planting density was low. With the continuous improvement of the three technologies, the corn density has continued to increase, but at this time, the overly dense planting method has led to uncoordinated light and temperature, mismatched soil fertility and poor ventilation, which have become limiting factors in corn planting.

[0003] Conservation tillage is a farming technique that uses less tillage or no tillage methods to sow crops under the conditions of covering the ground with crop straw and stubble or spreading livestock and poultry manure on the ground. Conservation tillage can effectively reduce soil wind and water erosion, improve soil fertility and soil moisture retention and drought resistance. While conservation tillage solves the problem of improving soil fertility, it also brings about the problem of insufficient space for returning straw to the field. After the soil fertility is improved, solving the problem of uncoordinated light and temperature and poor ventilation of corn has become the main contradiction restricting corn growth.

[0004] The unequal row spacing and density planting mode is to alternately plant wide rows and narrow rows, with a higher density near wide rows and a lower density near narrow rows. This method is conducive to ventilation and light transmission, reducing or avoiding group closure, and can also provide space for returning straw or organic fertilizer to the field (wide rows or empty rows for returning straw or organic fertilizer to the field), and land fallow rotation (wide rows or empty rows in the first year become narrow rows in the second year, and narrow rows in the first year become wide rows or empty rows in the second year, and are planted alternately). The unequal row spacing planting mode can not only coordinate light temperature and ventilation, but also fallow the land, provide space for returning straw to the field, and reduce the difficulty of returning straw to the field in conservation tillage. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a conservation tillage unequal row spacing and sparse and dense planting mode and a supporting device.

The unequal row spacing and unequal density planting pattern can not only coordinate light temperature and ventilation, but also idle the land, provide space for returning straw to the field, and reduce the difficulty of returning straw to the field in conservation tillage.

[0008] Among them, the three-space planting mode with different plant spacing includes the following steps:

The wide rows and empty rows are both straw returning belts, and the straw returned to the field last year is returned to the empty rows and wide rows to minimize the impact on the sowing operation. The narrow planting rows are evenly planted, and the narrow rows close to the empty rows are densely planted, and the density is 1.5 times that of the narrow rows close to the wide rows. The overall planting density is 5000 plants / mu.

[0015] Furthermore, the row spacing of the narrow rows is 40-45 cm; the row spacing of the empty rows is 115-125 cm, and the row spacing of the wide rows is 75-85 cm.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] like Figure 1 and Figure 2 As shown in the figure, a conservation tillage unequal row spacing and sparse planting pattern includes two types:

[0041] 1. Three-dimensional space planting mode with different plant spacing ( Figure 1): Three ridges are planted with 3 ridges and 1 ridge is empty. The 3 ridges are planted in uniform rows with a row spacing of 40 cm and a row spacing of 120 cm for empty rows. The empty rows are straw return belts, and the straw returned to the field last year is returned to the empty rows to minimize its impact on the sowing operation; the density of the side ridges among the 3 ridges should be larger, 1.5 times that of the middle ridge. In principle, the overall planting density is 5000 plants / mu.

[0042] 2. Four-ratio space planting mode with unequal row spacing and different plant spacing ( Figure 2 ): Four-ratio empty means 4 planted ridges and 1 empty ridge. The 4 planted ridges are uniform rows combined with wide and narrow rows, that is, uniform rows and wide and narrow rows alternate to form a planting pattern of narrow rows-wide rows-narrow rows-empty rows; the narrow row spacing is 40cm, the wide row spacing is 80cm, the empty row spacing is 120cm, both wide rows and empty rows are straw return belts, and the overall planting density is 5000 plants / mu in principle; when planting in 4 ridges, the one close to the empty rows is the denser planting belt, and the density is 1.5 times that of the one close to the wide rows.

[0043] like Figure 3-Figure 12 As shown, the present invention also proposes a supporting device for a protective tillage unequal row spacing and dense planting mode, including a planting frame 1 for movement, wherein a regulating component 2 and two groups of connecting frames are installed on the upper end of the planting frame 1, and the connecting frames are respectively a connecting frame 1 3 and a connecting frame 2 4, and the planting frame 1 supports and fixes the regulating component 2 and the connecting frame, and the connecting frame 1 3 and the connecting frame 2 4 are symmetrically arranged on the opposite side walls of the planting frame 1, and a driving component 5 is installed on the upper ends of the connecting frame 1 3 and the connecting frame 2 4, and the connecting frame 1 3 and the connecting frame 2 4 support the driving component 5, and the upper end of the driving component 5 is movable through the regulating component 2, and a sowing component is installed on the bottom wall of the planting frame 1, and the sowing component is provided with two groups, namely a sowing component 1 6 and a sowing component 2 7, and the sowing component 1 6 and the sowing component 2 7 are symmetrically placed with the horizontal center line of the planting frame 1 as the symmetry axis;

[0044] The driving assembly 5 includes a driving rod 8, a push rod 1 9, a push rod 2 10, a gear 1 11 and a gear 2 12. One end of the push rod 1 9 is movably connected to the driving rod 8, and one end of the push rod 2 10 is also movably connected to the driving rod 8. The push rod 1 9 is arranged at the upper end of the push rod 2 10, and the upper end of the driving rod 8 is movably arranged in the regulating assembly 2; the push rod 1 9 is sequentially installed with a ring member 1 13, a limit groove 6 14 and a ring member 2 15. The second gear 10 is provided with an insertion rod 16 and a limiting groove 3 17 in sequence, the inner bottom wall of the upper end of the gear 11 is provided with a limiting groove 5 18, the inner upper wall of the upper end of the gear 2 12 is provided with an insertion rod 2 19, the annular member 13 on the push rod 1 9 is movably connected to the upper end of the connecting frame 3, the annular member 2 15 on the push rod 1 9 is movably connected to the upper end of the connecting frame 2 4, the upper end of the gear 11 is movably sleeved in the annular member 13, and the other end of the push rod 2 10 is provided with a stopper 5 18, and the upper end of the gear 11 is provided with a stopper 5 18. The ends are movably penetrated through the upper end of the gear 11 in sequence, and the ring member 2 15 is arranged on the outer side of the connecting frame 2 4. The insertion rod 16 on the push rod 2 10 is movably connected in the limiting groove 5 18 on the upper end of the gear 1 11. The limiting groove 3 17 on the push rod 2 10 is movably sleeved with a sleeve rod 20 on the outer side. The sleeve rod 20 is provided with a spiral groove 21 at one end close to the gear 11. The spiral groove 21 is arranged at the lower end of the limiting groove 6 14 on the push rod 1 9. The sleeve rod 20 is away from the gear A limiting groove 22 is provided at one end of the first gear 11, the second gear 12 is movably sleeved on the outside of the sleeve rod 20, the upper end of the second gear 12 is movably clamped in the limiting groove 6 14 on the push rod 1 9, the plug rod 2 19 on the second gear 12 is movably clamped in the spiral groove 21, and a limiting rod 23 is provided on the connecting frame 24, the upper end of the limiting rod 23 is movably clamped in the limiting groove 22 of the sleeve rod 20, and the setting of the limiting rod 23 enables the sleeve rod 20 to only move horizontally;

[0045] It should be noted that when the driving rod 8 swings along the slide groove 2 41 on the regulating component 2, the pushing rod 2 10 rotates as the center of the circle, and the pushing rod 2 10 drives the insertion rod 1 16 and the limiting groove 3 17 to rotate. Since the insertion rod 1 16 is movably arranged in the limiting groove 5 18, the pushing rod 2 10 drives the gear 1 11 to rotate in an arc through the insertion rod 1 16 and the limiting groove 5 18, and the driving rod 8 drives the pushing rod 1 9 to run in an arc, and the pushing rod 1 9 drives the ring part 1 13, the limiting groove 6 14 and the ring part 2 15 to move in an arc. Due to the action of the limiting rod 23, the sleeve rod 20 does not rotate with the pushing rod 1 9 and the pushing rod 2 10. Since the gear 2 12 is movably connected to the sleeve rod 20 through the insertion rod 2 19 and the spiral groove 21, the sleeve rod 20 does not move, and the gear 2 12 does not move; the driving rod 8 moves along the regulating component 2 When the slide groove 140 on the upper part swings, the push rod 19 cannot move under the limit of the connecting frame 13 and the connecting frame 24, and the driving rod 8 performs an arc motion with the movable connection with the pushing rod 19 as the rotation axis. The lower end of the driving rod 8 drives the pushing rod 21 to pull and pull, and the pushing rod 210 drives the insertion rod 16 and the limiting groove 3 17 to move. The insertion rod 16 slides along the limiting groove 5 18 and does not drive the gear 11. The pushing rod 210 drives the sleeve rod 20 to pull and pull through the limiting groove 3 17, and the sleeve rod 20 drives the spiral groove 21 to move back and forth. Since the upper end of the gear 2 12 is clamped in the limiting groove 6 14 of the pushing rod 19, the gear 2 12 cannot move back and forth with the sleeve rod 20, so the insertion rod 21 moves along the spiral groove 21, driving the gear 2 12 to rotate in an arc.

[0046] In this embodiment, the upper wall of the planting rack 1 is provided with a limit groove 1 24 and a limit groove 25, and the bottom wall of the planting rack 1 is provided with a card slot 1 26 and a card slot 27. A gear condition 1 28 is movably engaged in the limit groove 1 24, and a gear condition 29 is movably engaged in the limit groove 25. The gear condition 1 28 is meshed and connected with the lower end of the gear 1 11, and the gear condition 29 is meshed and connected with the lower end of the gear 2 12. When the gear 1 11 rotates, it can drive the gear condition 1 28 to slide along the limit groove 1 24, and when the gear 2 12 rotates, it can drive the gear condition 29 to slide along the limit groove 2 25 slides; one end of the sowing component 1 6 is connected to the gear condition 1 28, and the other end of the sowing component 1 6 is movably connected in the card slot 1 26, one end of the sowing component 2 7 is connected to the gear condition 2 29, and the other end of the sowing component 2 7 is movably connected in the card slot 27, and the sowing component 1 6 and the sowing component 2 7 have the same structure, and the sowing component 2 7 includes a slider 1 30 and a slider 2 31, and the slider 2 31 is movably connected in the limit groove 25, and the upper end of the slider 2 31 is connected to the bottom wall of the gear condition 29, and the slider 1 30 is movably connected. The movable card is arranged in the second card slot 27, and the bottom wall of the planting frame 1 is also provided with a fixed plate 32 and a pulley 33. A spring 24 is installed between the fixed plate 32 and the slider 1 30, and a connecting rope 35 is installed between the slider 1 30 and the slider 2 31. The connecting rope 35 is movably sleeved on the pulley 33. The slider 2 31 and the bottom wall of the slider 2 31 are both provided with a seeder 36 for sowing corn; when the gear condition 29 drives the slider 2 31 to move toward the edge of the planting frame 1, the slider 2 31 drives the slider 1 30 along the card slot 27 to the planting frame through the connecting rope 35. When the slider 1 moves toward the other side of the planting rack 1, the distance between the slider 1 30 and the slider 2 31 increases, and the distance between the two groups of seed drills 36 increases. The spring 2 34 is in a stretched state. When the gear condition 29 drives the slider 2 31 to move away from the side of the planting rack 1, the connecting rope 35 between the slider 1 30 and the slider 2 31 is in a relaxed state. The spring 2 34 drives the slider 1 30 to move along the slot 2 27 away from the other side of the planting rack 1, and the distance between the slider 1 30 and the slider 2 31 decreases, and the distance between the two groups of seed drills 36 also decreases. Similarly, the movement mode of the seeding component 6 is as above.

[0047] The planting rack 1 is also provided with a handle 37, and the regulating component 2 includes a support plate 38, and the support plate 38 is provided on the handle 37, and an arc plate 39 is installed on the support plate 38, and a slide groove 1 40 and a slide groove 2 41 are provided in the arc plate 39, and the slide groove 1 40 and the slide groove 2 41 are vertically connected, and a baffle plate 42 is installed on one side of the arc plate 39, and a spring 1 43 and a telescopic rod 44 are installed on the baffle plate 42, and a pushing plate 45 is installed at the ends of the spring 1 43 and the telescopic rod 44, and a plurality of groups of card slots 46 for limiting are installed on the side wall of the pushing plate 45, The upper end of the driving rod 8 is movably connected in the slide groove 1 40 and the slide groove 2 41; initially, the spring 1 43 drives the pushing plate 45 to squeeze the driving rod 8, and the driving rod 8 is stuck in the slot 46. When the position of the driving rod 8 needs to be adjusted, one hand pushes the pushing plate 45 toward the baffle 42, and the other hand adjusts the position of the driving rod 8. After the position is adjusted, the pushing plate 45 is released. Under the action of the spring 1 43, the pushing plate 45 fixes the driving rod 8 between the slot 46 and the side wall of the slide groove 1 40 or the slide groove 2 41; the side wall of the planting rack 1 is installed with a driving wheel 47 to facilitate the movement of the planting rack 1.

[0048] The specific usage is as follows:

[0049] The sowing power source is driven by a motor. The corn seeds are placed in the sowing machine 36. If three different spacing planting patterns are required ( Figure 1 ) When planting, the seed drills 36 on the seeding assembly 2 7 are separated under the action of the gear condition 29, and the spacing is adjusted to 80 cm. The seed drills 36 on the seeding assembly 1 6 are fixed in place and arranged in the middle of the seed drills 36 on the seeding assembly 2 7. Only one group of seed drills 36 works, and the planting density of the seed drills 36 on the seeding assembly 2 7 is 1.5 times that of the seed drills 36 on the seeding assembly 1 6;

[0050] If you need to plant four-space planting patterns with different row spacing and plant spacing ( Figure 2 ) When planting, the seeder 36 on the sowing component 27 is separated under the action of the gear condition 29, and the spacing is adjusted to 160 cm. The seeder 36 on the sowing component 16 is separated under the action of the gear condition 128, and the spacing is adjusted to 80 cm. The planting density of the seeder 36 on the sowing component 27 is 1.5 times that of the seeder 36 on the sowing component 16.

[0051] The adjustment process of the sowing machine 36 on the sowing assembly 6 is as follows:

[0052] When the driving rod 8 swings along the slide groove 2 41 on the regulating component 2, the pushing rod 2 10 rotates as the center of the circle, and the pushing rod 2 10 drives the insertion rod 1 16 and the limiting groove 3 17 to rotate. Since the insertion rod 1 16 is movably arranged in the limiting groove 5 18, the pushing rod 2 10 drives the gear 1 11 to rotate in an arc through the insertion rod 1 16 and the limiting groove 5 18, and the driving rod 8 drives the pushing rod 1 9 to run in an arc, and the pushing rod 1 9 drives the annular member 13, the limiting groove 6 14 and the annular member 2 15 to move in an arc. Due to the action of the limiting rod 23, the sleeve rod 20 does not rotate with the pushing rod 1 9 and the pushing rod 2 10. Since the gear 2 12 is movably connected to the sleeve rod 20 through the insertion rod 2 19 and the spiral groove 21, the sleeve rod 20 does not move, and the gear 2 12 does not move;

[0053] The movement of gear 11 drives the gear condition 128 meshing therewith to move. When the gear condition 128 drives the slider 2 31 to move toward the side of the planting rack 1, the slider 2 31 drives the slider 1 30 along the slot 1 26 to move toward the other side of the planting rack 1 through the connecting rope 35. The distance between the slider 1 30 and the slider 2 31 increases, and the distance between the two groups of seed drills 36 increases. The spring 2 34 is in a stretched state. When the gear condition 128 drives the slider 2 31 to move away from the side of the planting rack 1, the connecting rope 35 between the slider 1 30 and the slider 2 31 is in a relaxed state. The spring 2 34 drives the slider 1 30 to move along the slot 1 26 to move away from the other side of the planting rack 1, and the distance between the slider 1 30 and the slider 2 31 decreases, and the distance between the two groups of seed drills 36 also decreases.

[0054] The adjustment process of the sowing machine 36 on the sowing assembly 2 7 is as follows:

[0055] When the driving rod 8 swings along the slide groove 1 40 on the regulating component 2, the pushing rod 1 9 cannot move under the limit of the connecting frame 1 3 and the connecting frame 2 4, and the driving rod 8 performs arc motion with the movable connection with the pushing rod 1 9 as the rotation axis, and the lower end of the driving rod 8 drives the pushing rod 2 10 to pull and draw, and the pushing rod 2 10 drives the insertion rod 1 16 and the limiting groove 3 17 to move, and the insertion rod 1 16 slides along the limiting groove 5 18 without driving the gear 1 11, and the pushing rod 2 10 drives the sleeve rod 20 to pull and draw through the limiting groove 3 17, and the sleeve rod 20 drives the spiral groove 21 to move back and forth. Since the upper end of the gear 2 12 is clamped in the limiting groove 6 14 of the pushing rod 1 9, the gear 2 12 cannot move back and forth with the sleeve rod 20, so the insertion rod 2 19 moves along the spiral groove 21, driving the gear 2 12 to rotate in an arc;

[0056] The movement of gear 2 12 drives the meshing gear condition 29 to move. When gear condition 29 drives slider 2 31 to move toward the edge of the planting rack 1, slider 2 31 drives slider 1 30 along slot 27 to move toward the other edge of the planting rack 1 through the connecting rope 35. The distance between slider 1 30 and slider 2 31 increases, and the distance between the two groups of seed drills 36 increases. Spring 2 34 is in a stretched state. When gear condition 29 drives slider 2 31 to move away from the edge of the planting rack 1, the connecting rope 35 between slider 1 30 and slider 2 31 is in a relaxed state. Spring 2 34 drives slider 1 30 to move along slot 27 to move away from the other edge of the planting rack 1, and the distance between slider 1 30 and slider 2 31 decreases, and the distance between the two groups of seed drills 36 also decreases.

[0057] The adjustment process of the driving rod 8 is as follows:

[0058] Initially, spring 1 43 drives the pushing plate 45 to squeeze the driving rod 8, and the driving rod 8 is stuck in the slot 46. When the position of the driving rod 8 needs to be adjusted, the staff pushes the pushing plate 45 toward the baffle 42 with one hand and adjusts the position of the driving rod 8 with the other hand. After the position is adjusted, the pushing plate 45 is released. Under the action of spring 1 43, the pushing plate 45 fixes the driving rod 8 between the slot 46 and the side wall of the slide slot 1 40 or the slide slot 2 41.
