Description

A type of dryland wide-narrow row ridging and mulching corn dense planting machine Technical Field

This invention relates to the field of corn planting technology, and in particular to a corn dense planting machine for wide and narrow row ridging and mulching in dryland.

Background Technology

According to Chinese Patent Publication No. CN201820944707.1, a patent document entitled "A Dryland Seeder" is disclosed. The patent document describes that by cooperating between a seed storage box and a precision seeding device, the seeding amount can be adjusted to achieve precision seeding. However, it cannot be used for direct planting of stem plants. At the same time, the technology cannot achieve wide-row ridging and mulching and narrow-row leveling, that is, it cannot achieve long-term preservation of soil moisture in the planting area.

Therefore, in order to solve the problem of low rainfall in dry land, we need to use ridges to collect rainwater through micro-topography and use mulching technology to reduce soil evaporation, so as to maximize the use of rainwater in dry land and ensure the growth and development of corn. Therefore, we need to implement a ridge and mulching planting scheme for this part of dry land. However, conventional planting techniques cannot retain rainwater for a long time, which can easily lead to rapid evaporation of rainwater in arid areas, thus failing to achieve the purpose of planting.

To address this, we designed a high-density corn planter for wide and narrow row ridging and mulching in dryland areas.

Summary of the Invention

The purpose of this invention is to solve the problem of rapid evaporation of rainwater in arid areas, which makes it impossible to achieve the purpose of planting, and to propose a wide and narrow row ridge-mulching corn dense planting machine for dry land.

To achieve the above objectives, the present invention adopts the following technical solution:

A dryland wide and narrow row ridging and mulching corn dense planting planter includes a planter body placed on the land, with multiple corn stalks placed inside the planter body. The planter body moves via electric wheels. The front end of the planter body is provided with a soil turning section for tilling the soil, wherein the soil turning section is used to till the soil into a state where the middle is a narrow row and the sides are ridged.

The seeder body has film-wrapping bundles on both sides for covering the ridged land with film, multiple sets of conical side plates on both sides for expanding the soil, and triangular push blocks on both sides for pushing corn stalks into the soil pit. The seeder body also has Y-shaped inserts on both sides for inserting into the soil and for spreading the film-wrapping bundles.

Preferably, the soil-moving and turning section includes a shovel section and a turning section connected end to end, wherein the end of the shovel section is triangular and the two sides of the turning section are semi-circular.

Preferably, the seeder body has grooves on both sides, and a film support is provided in the grooves. The film is placed on the film support, and after the film is placed, a flat film is formed on the ridged surface and a cover film is formed at the junction with the corn stalks. The grooves are provided with triangular blocks for changing the unfolding direction of the flat film.

Preferably, the seeder body has side supports and bottom supports that are connected end to end and arranged in an L-shape on both sides. The bottom support has a top sliding groove, and the side supports have inclined storage cavities for storing multiple corn stalks. The top sliding groove is connected to the storage cavity. The triangular push block is reset and slides in the top sliding groove by a first reset spring, and the triangular push block has a triangular inclined surface on the side facing the storage cavity.

Preferably, the bottom support has pressing holes for storing multiple sets of conical side plates, and the bottom support has a side outlet on the side away from the soil turning part to facilitate the removal of corn stalks. The top of the bottom support has a rotating C-shaped ring, which pushes multiple sets of conical side plates to open and lower. The top slide groove sidewall is provided with a trigger.

Preferably, the bottom support has a rotating groove coaxial with the pressing hole, and a sliding hole communicating with the rotating groove. A side plate connected to the conical side plate is provided in the sliding hole. An inclined groove is provided at the top of the side plate. An inclined long plate extending into the rotating groove and abutting against the side plate is provided at the bottom of the C-shaped ring. A bottom block is provided at the bottom of the inclined long plate. A rubber pad is provided at the bottom of the side plate. A second return spring is connected between the side plate and the bottom support.

The side plate has a first chamfer on the side facing the inclined long plate, and the inclined groove has a second chamfer on the end opposite to the first chamfer.

Preferably, the bottom support has a bottom cavity, and the bottom cavity has a plurality of linearly arranged Y-shaped inserts. The plurality of linearly arranged Y-shaped inserts are pressed against the bottom cavity by a push plate and a compression spring. The bottom support also has an electromagnetic pressing part that pushes the Y-shaped inserts down.

The beneficial effects of this invention are as follows:

1. This invention uses a bulldozing and tilling unit to till the soil into a state where there are narrow rows in the middle and raised beds on both sides. This shape ensures that after the raised beds are covered with a flat film, water evaporation is reduced. During rainfall, the raised beds are higher than the narrow rows, so rainwater will be stored in the narrow rows. Since the raised beds and narrow rows are interconnected, water that was originally stored in the narrow rows will seep into the raised beds, making the originally dry raised beds moist. This completes the water storage operation while avoiding the problem of water accumulation in the narrow rows.

2. This invention uses a C-shaped ring to push multiple sets of conical side plates to open and descend. When the multiple conical side plates are in a closed state, they are pressed down and will penetrate the soil. Then, after the multiple conical side plates expand outward, they will form a planting depression, which facilitates the planting of corn stalks. Since there is a second return spring connecting the side plate and the bottom support, the conical side plate will quickly return to its original position when there is no external force, which facilitates subsequent penetration into the soil and expansion of the soil. That is, the three steps of penetration into the soil, expansion of the soil, and removal from the soil are completed.

Detailed Implementation

Referring to Figures 1-12, a dryland wide-narrow row ridging and mulching corn dense planting planter includes a planter body 1 placed on the land. Multiple corn stalks 10 are placed inside the planter body 1. The planter body 1 moves through an electric wheel 4. Therefore, the electric wheel 4 drives the planter body 1 to move forward, thereby turning over the soil.

Referring to Figures 1-3, the front end of the seeder body 1 is equipped with a soil turning section 5 for tilling the soil. As the soil turning section 5 moves forward, it pushes the soil turning section 5, which penetrates into the soil, to move forward and complete the subsequent tilling operation. It should be noted that the soil turning section 5 is adjusted by an external hydraulic push mechanism to control the depth of the soil turning section 5 penetrating into the soil, thereby controlling the depth of tilling and the height of the raised beds 3 on both sides.

Referring to Figure 3, the soil turning section 5 includes a shovel section 51 and a turning section 52 connected end to end. The end of the shovel section 51 is triangular, and the two sides of the turning section 52 are semi-circular. The shovel section 51 with the triangular end will first turn the soil of the narrow row 2 from the middle to both sides. With the action of the turning section 52, the soil turned on both sides will be turned over again and flipped over to form the raised ground 3.

The soil turning section 5 is used to turn the soil into a state with narrow rows 2 in the middle and raised beds 3 on both sides, as shown in Figure 1. This shape can reduce water evaporation after the raised beds 3 are covered with a flat film 71. During rainfall, the raised beds 3 are higher than the narrow rows 2, so the rainwater will be stored in the narrow rows 2. The raised beds 3 and the narrow rows 2 are connected to each other, which will cause the water that was originally stored in the narrow rows 2 to seep into the raised beds 3, thus making the originally dry raised beds 3 wet. This completes the water storage operation for rainwater, while avoiding the problem of water accumulation in the narrow rows 2.

Furthermore, due to the setting of the flat film 71, it can be further ensured that the moisture in the raised field 3 will not evaporate due to sunlight. Instead, the moisture temporarily stored in the raised field 3 will be absorbed by the corn stalks 10, which will improve the water utilization rate and avoid water loss caused by direct sunlight.

The seeder body 1 has film-wrapping bundles 7 on both sides for covering the ridged ground 3 with film. The seeder body 1 has grooves 9 on both sides, and film supports 6 are provided in the grooves 9. Triangular blocks 8 are provided in the grooves 9 for changing the unfolding direction of the flat film 71. The film-wrapping bundles 7 are placed on the film supports 6. In this way, the film-wrapping bundles 7 are placed on the film supports 6 while the seeder body 1 is moving forward. The film is then placed on the upper surface of the ridged ground 3.

Referring to Figures 6 and 7, both sides of the seeder body 1 are provided with side supports 11 and bottom supports 12 arranged in an L-shape and connected end to end. The bottom support 12 has a top groove 13, and the side supports 11 have an inclined storage cavity 23 for storing multiple corn stalks 10. The top groove 13 is connected to the storage cavity 23, which ensures that the corn stalks 10 in the storage cavity 23 enter the storage cavity 23 in sequence. That is, the corn stalks 10 originally in the top groove 13 are pushed into the pressing hole 14 and replenished.

The seeder body 1 is also provided with triangular push blocks 28 on both sides for pushing corn stalks 10 into the soil pit. The bottom support 12 is provided with pressing holes 14 for storing multiple sets of conical side plates 17. The triangular push blocks 28 are reset and slid in the top slide groove 13 by the first reset spring 29. The triangular push blocks 28 are provided with triangular inclined surfaces on the side facing the receiving cavity 23. This can ensure that after the triangular push blocks 28 push the previous corn stalk 10 in, the corn stalk 10 that accidentally entered the top slide groove 13 will be squeezed back into the receiving cavity 23 during the retraction process. After the triangular push blocks 28 are completely retracted, the corn stalk 10 will fall to the front of the triangular push blocks 28 located in the top slide groove 13, which is convenient for the next push.

The top slide 13 has a trigger 19 on its side wall. Referring to Figure 6, when the C-ring 20 rotates to the position shown in the figure, the notch of the C-ring 20 faces the triangular push block 28. At this time, the trigger 19 will be energized, which will activate the electromagnetic generator. This causes the triangular push block 28 with a magnet to pop out and push the corn stalk 10 of the top slide 13 into the pressing hole 14. The electromagnetic generator is existing technology and only serves to push the triangular push block 28 out in this technical solution. After the C-ring 20 rotates again, the power is cut off, and the triangular push block 28 is reset under the action of the first reset spring 29. This will not be elaborated on further here.

The bottom support 12 has a side outlet 24 on the side away from the soil turning part 5 to facilitate the removal of corn stalks 10. A C-shaped ring 20 rotates on the top of the bottom support 12. The C-shaped ring 20 is driven by an external drive mechanism to rotate. With the continuous forward movement of the seeder body 1, this ensures that after the notch of the C-shaped ring 20 is aligned with the side outlet 24, the corn stalks 10 located in the pressing hole 14 will leave from the side outlet 24, thus completing the planting of corn stalks 10.

Referring to Figure 9, the seeder body 1 has multiple sets of conical side plates 17 on both sides for expanding the soil. The C-shaped ring 20 pushes the multiple sets of conical side plates 17 to open and lower. When the multiple conical side plates 17 are in a closed state, they will press down and penetrate the soil. Then, after the multiple conical side plates 17 expand outward, they will form a planting depression, which is convenient for planting corn stalks 10. Since there is a second return spring connecting the side plate 18 and the bottom support 12, the conical side plates 17 will quickly return to their original position when no external force is applied, which is convenient for subsequent penetration into the soil and expansion of the soil. That is, the three steps of penetration into the soil, expansion of the soil, and removal from the soil are completed.

Referring to Figures 4 and 5, the bottom support 12 has a rotating groove 16 coaxial with the pressing hole 14, and a sliding hole 15 communicating with the rotating groove 16. The sliding hole 15 has a side plate 18 connected to the conical side plate 17. The top of the side plate 18 has an inclined groove 27. The bottom of the C-shaped ring 20 has an inclined long plate 21 that extends into the rotating groove 16 and abuts against the side plate 18. The bottom of the inclined long plate 21 has a bottom block 22. This arrangement ensures that when the C-shaped ring 20 rotates, the inclined long plate 21 will first abut against the side plate 18 and descend, but the conical side plate 17 will not open, thus completing the step of penetrating the soil.

As the C-shaped ring 20 continues to rotate, the bottom block 22 at the bottom of the inclined long plate 21 will press the side plate 18. Since the side plate 18 has a rubber pad at the bottom, this will cause the bottom block 22 to be squeezed into the inclined groove 27. As the C-shaped ring 20 rotates, it will carry the side plate 18 to slide along the radius on the sliding hole 15, thus realizing the opening steps of multiple conical side plates 17, which completes the step of expanding the soil.

Then, the side plate 18 is provided with a first chamfer 25 on the side facing the inclined long plate 21, and the inclined groove 27 is provided with a second chamfer 26 on the end opposite to the first chamfer 25. After the bottom block 22 slides to the end in the inclined groove 27, it will slide away from the side plate 18 along the second chamfer 26. Under the action of the second return spring, it will quickly return to its original position without external force, which facilitates subsequent penetration into the soil and expansion of the soil, thus completing the final step of leaving the soil.

It should be noted that planting one corn stalk 10 is completed by rotating the C-shaped ring 20 once.

Referring to Figure 8, the bottom support 12 has a bottom cavity 33, and multiple linearly arranged Y-shaped inserts 30 are provided in the bottom cavity 33. The multiple linearly arranged Y-shaped inserts 30 are pressed against the bottom cavity 33 by the push plate 31 and the compression spring 32. The bottom support 12 is provided with an electromagnetic pressing part that pushes the Y-shaped inserts 30 down. The two sides of the seeder body 1 are also provided with Y-shaped inserts 30 that are inserted into the soil and used to open the film wrapping bundle 7. It should be noted that after the triangular push block 28 moves to push the corn stalk 10 to the pressing hole 14, it will trigger the opening of the electromagnetic pressing part. The function of the electromagnetic pressing part is to push the foremost Y-shaped insert 30 into the soil. Since the push plate 31 and the compression spring 32 are set, it can be ensured that the Y-shaped insert 30 is always in close contact with the end of the bottom cavity 33. The electromagnetic pressing part is existing technology and will not be discussed in detail here.

Referring to Figures 10-12, after the film-covering wrapping 7 is laid out, a flat film 71 is formed on the surface of the raised ground 3, and a cover film 72 is formed at the junction with the corn stalks 10. In this way, the Y-shaped insert 30 inserted into the soil will form a cover film 72 on the flat film 71, which facilitates the collection of rainwater and the moisturization of the roots of the corn stalks 10. Since the V-shaped rods on both sides of the Y-shaped insert 30 are set perpendicular to the bottom rod, it can ensure that the corn stalks 10 are supported.

The working principle of this invention is as follows: During the forward movement of the soil-turning section 5, the soil-turning section 5, which penetrates the soil, will be pushed forward. In conjunction with the action of the soil-turning section 52, the soil turned over on both sides will be flipped over again and turned over to form a raised bed 3 on both sides. The seeder body 1 is provided with multiple sets of conical side plates 17 on both sides for expanding the soil. The C-shaped ring 20 pushes the multiple sets of conical side plates 17 to open and lower. When the multiple conical side plates 17 are in a closed state, they will be pressed down and penetrate the soil. Then, after the multiple conical side plates 17 expand outward, a planting depression will be formed, which is convenient for planting corn stalks 10. Since the side plate 18 is connected to the bottom support 12 with a second return spring, the conical side plate 17 will quickly return to its original position when it is not subjected to external force, which is convenient for subsequent penetration into the soil and expansion of the soil. That is, the three steps of penetration into the soil, expansion of the soil, and removal from the soil are completed.

During rainfall, the raised plot 3 is higher than the narrow row plot 2, so the rainwater will be stored in the narrow row plot 2. Since the raised plot 3 and the narrow row plot 2 are connected, the water that was originally stored in the narrow row plot 2 will seep into the raised plot 3, thus making the originally dry raised plot 3 wet. This completes the water storage operation and avoids the problem of water accumulation in the narrow row plot 2.

Because of the flat film 71, the moisture in the raised field 3 will not evaporate due to sunlight. Instead, the moisture temporarily stored in the raised field 3 will be absorbed by the corn stalks 10, which will improve the water utilization rate and avoid water loss caused by direct sunlight.

The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
