Description

Technical Field

[0001] The invention relates to the technical field of agriculture, in particular to a sowing and covering soil device for desert grasslands. Background Art

[0002] The soil conditions in desert steppe areas are poor and need to be improved to increase soil fertility and water retention capacity. Seeding and covering equipment improves soil structure through reasonable fertilization, loosening soil and other measures to provide a good soil environment for vegetation growth.

[0003] In many seeding and covering equipment, in order to improve the working efficiency and ensure the quality of cultivated land, one or more rows of fixed soil-breaking objects, such as plowshares, are used. The plowshares plow the land while the equipment moves forward, and after plowing, the land will present a row of gullies;

[0004] The ground in desert steppes is usually uneven, with ups and downs and obstacles such as stones. Since the plowshares are fixed together in rows, and each independent plowshare faces a different height of land, some plowshares will not reach the expected tillage depth because the ground is low or sunken, while some plowshares will cause the soil to be over-turned because the ground is protruding.

[0005] This uneven arable land depth will directly affect the planting depth of seeds. If the planting depth is too shallow, the seeds will not be adequately covered and protected by the soil, and will be easily affected by adverse factors such as wind erosion and drought. If the planting depth is too deep, it may increase the difficulty of seed germination, or even cause the seeds to fail to germinate.

[0006] When the seeds enter the cultivated gully, they are usually moved along the top of the gully by the covering plate, pushing part of the soil into the gully. Due to the uneven ground, the covering plate cannot push all the soil back into the gully, and the covering plate moves horizontally along the top of the gully. This movement method also easily causes part of the soil outside the gully to be pressed on both sides of the gully, rather than pushing enough soil back into the gully.

[0007] Therefore, there is very little soil covering the seeds, and due to the unevenness of the ground, the soil in each groove is also loose, which cannot provide sufficient protection and support for the seeds. This will increase the risk of seeds being affected by adverse factors such as wind erosion and drought, and reduce the germination rate and growth quality of the seeds. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the sowing and covering soil equipment breaks the ground to form gullies through multiple sets of tillage discs during driving, and seeds fall into the gullies. The soil on both sides of the gullies is collected by the tillage discs and pushed back into the gullies, and then pressed across the soil surface. The equipment uses tension springs and Y-shaped support rods to automatically adjust the contact force and depth between the tillage discs and the ground to ensure that it adapts to different terrains. The tillage discs are adjusted synchronously with the tillage discs to ensure that each gully is independently and evenly covered with soil, avoiding uneven soil covering and soil compaction problems caused by uneven ground.

[0021] 2. In the present invention, two tillage plates work together to easily break up the soil and form furrows. Subsequently, the wide tillage plate collects soil on both sides, and by pushing and moving closer, the soil is gathered into the furrows and squeezed. This process ensures that the soil enters the furrows and is in close contact with the seeds, thereby promoting the germination and growth of the seeds.

[0022] 3. In the present invention, the tillage disc can be flexibly tilted and detoured when encountering obstacles or inclined ground. The smooth design on both sides facilitates adaptation to different terrains. The slider slides along the arc-shaped slide rod and the groove to ensure that the tillage disc swings smoothly, adapts to various ground conditions, and achieves efficient tillage effects.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0034] See also Figure 1-Figure 6 As shown, a sowing and covering soil equipment for desert grasslands includes a sowing and covering soil equipment body 1 and multiple groups of tillage plates 6, including multiple Y-shaped support rods 7, which are arranged in rows at equal intervals in the sowing and covering soil equipment body 1, and the two ends below the Y-shaped support rods 7 are respectively fixedly connected to the outer wall of one of the tillage plates 6, multiple tension springs 19 are fixedly installed on the top of the Y-shaped support rods 7, multiple groups of tillage plates 8, each group consists of two tillage plates 8, and are arranged in rows at equal intervals on one side of each group of tillage plates 6, each group of tillage plates 8 corresponds to each group of tillage plates 6, and a bracket 5 is arranged on one side of the sowing and covering soil equipment body 1 and corresponds to the multiple tension springs 19.

[0035] During the driving process of the sowing and covering soil equipment body 1, multiple groups of tillage discs 6 are used to break the soil. The contacting side of the two tillage discs 6 of each group breaks the soil to form gullies, and then the seeds will enter the gullies. After the soil forms gullies, the soil will pile up on both sides of the tillage disc 6. The tillage disc 8 is larger than the tillage disc 6, so the piled soil will enter the two tillage discs 8 of each group;

[0036] The openings of the two tillage plates 8 are large so that the soil accumulated on both sides of the gully can enter between the two tillage plates 8. Then, as the tillage plates 8 move, the soil gradually approaches the position where the two tillage plates 8 are close to each other, and is then pushed together by the tillage plates 8, and finally squeezed by the position where the two tillage plates 8 are closest to each other. Finally, the tillage plates 8 pass over the soil and press the soil.

[0037] The bracket 5 supports a plurality of tension springs 19 on one side of the main body 1 of the sowing and covering equipment. The tension springs 19 continuously squeeze the Y-shaped support rod 7 and the tillage plate 6, so that the tillage plate 6 is close to the ground, so that each set of tillage plates 6 can adjust their own distance according to the different depths of the land.

[0038] The tension spring 19 and the Y-shaped support rod 7 are both inclined, so the extrusion of the tillage disc 6 is downward and forward, so that the force of the tillage disc 6 against the ground can be transmitted to the tension spring 19 and the bracket 5, so that this force is brought to the sowing and covering equipment body 1 through the bracket 5, avoiding the tension spring 19 from deforming to the side;

[0039] After the downward depth of the tillage plate 6 changes, the tillage plate 8 will move along with the tillage plate 6, so the tillage plate 8 can cover each gully with soil separately, and will not be affected by the uneven ground. Moreover, the tillage plate 8 gathers the broken soil toward the inside of the gully instead of directly pressing on the soil, so the soil will not be compacted on both sides of the gully.

[0040] See also Figure 1-Figure 5 There are multiple groups of tillage discs 6 arranged in rows at equal intervals, each group consists of two tillage discs 6, and each group of tillage discs 6 is located below one of the Y-shaped support rods 7.

[0041] Multiple groups of tillage plates 6 are convenient for simultaneously tilling the land in rows, and the Y-shaped support rods 7 corresponding to the tillage plates 6 are also convenient for supporting and fixing the positions of the tillage plates 6, and allowing the tillage plates 6 to be continuously pushed toward the ground. The combination of two tillage plates 6 is convenient for breaking up the land and pushing the soil to one side.

[0042] See also Figure 6 Each set of tillage plates 6 and each set of tillage plates 8 are V-shaped, and the opening of the tillage plates 6 corresponds to the opening of the tillage plates 8. The tillage plates 8 are larger than the tillage plates 6, and the opening of the tillage plates 8 is also wider than the tillage plates 6.

[0043] The combination of the two tillage discs 6 facilitates breaking the soil, and then the soil will be pushed to one side of the two tillage discs 6. The openings of the two tillage discs 8 are larger than the tillage discs 6, so that the soil accumulated on both sides of each set of tillage discs 6 can enter between the two tillage discs 8;

[0044] As the tillage disc 8 moves, the soil gradually approaches the position where the two tillage discs 8 are close to each other, and is then pushed together by the tillage discs 8, and finally squeezed by the position where the two tillage discs 8 are closest to each other. Finally, the tillage disc 8 passes over the soil and presses the soil. Pressing the soil can make the seeds contact the soil more closely, which is beneficial for the seeds to absorb moisture and nutrients in the soil and improve the germination rate and growth rate of the seeds.

[0045] See also Figure 3 An arc rod 10 is fixedly installed on the outer wall of the tillage plate 8, and a connecting rod 9 is fixedly connected between the outer wall of the Y-shaped support rod 7 and the outer wall of the arc rod 10.

[0046] The arc rod 10 is used to fix two adjacent tillage plates 8 together, and then the connecting rod 9 is used to fix the Y-shaped support rod 7 and the arc rod 10 together, thereby connecting the tillage plate 8 to the tillage plate 6, so that when the tillage plate 6 moves its own position, the tillage plate 8 can move with the tillage plate 6.

[0047] See also Figure 1-Figure 2 A lower frame 23 is fixedly installed on the outer wall of the sowing and covering equipment body 1 , an upper frame 22 is fixedly installed on the top of the lower frame 23 , and an outer wall of the bracket 5 is fixedly connected to an outer wall of the upper frame 22 .

[0048] The lower frame 23 is fixed on the main body 1 of the sowing and covering equipment, and then supports and fixes the upper frame 22, so as to facilitate fixing the position of the bracket 5 through the upper frame 22, so that the bracket 5 has a better load-bearing capacity.

[0049] See also Figure 1-Figure 2 A support plate 4 is fixedly installed on the inner wall of the upper frame 22, and a plurality of circular openings 25 are opened on the support plate 4. A sowing box 2 is fixedly installed on the inner wall of the circular opening 25. A planting transmission pipe 3 is fixedly connected to the bottom end of the sowing box 2. A discharge port 12 is opened at one end of the planting transmission pipe 3 away from the sowing box 2, and the discharge port 12 is located between the two tillage plates 6.

[0050] The support plate 4 is fixed on the upper frame 22 and supports and fixes multiple seeding boxes 2. The seeding boxes 2 are used to store seeds. Then the circular opening 25 provides space for the planting transmission tube 3 to extend to the bottom of the upper frame 22. When the tillage plate 6 breaks the soil, the seeds will flow along the planting transmission tube 3 and spill out through the discharge port 12, and then enter the ditch.

[0051] See also Figure 4 The Y-shaped support rod 7 is provided with a slot 24, and the inner wall of the slot 24 is slidably connected with a sleeve rod 17. A circular fixing plate 18 is fixedly installed at one end of the sleeve rod 17 away from the Y-shaped support rod 7. A tension spring 19 is fixedly installed between the bottom of the circular fixing plate 18 and the top of the Y-shaped support rod 7, and the sleeve rod 17 is located outside the tension spring 19.

[0052] When the stretch spring 19 squeezes the Y-shaped support rod 7, the Y-shaped support rod 7 will slide along the sleeve rod 17 when encountering soil of varying depths, and then the Y-shaped support rod 7 will squeeze the stretch spring 19. When the stretch spring 19 is squeezed, it will shrink toward the circular fixing plate 18. The slot 24 provides space for the sleeve rod 17 to enter the Y-shaped support rod 7. The circular fixing plate 18 also limits the stretch spring 19 to prevent the stretch spring 19 from sliding out of the sleeve rod 17 after being squeezed. The sleeve rod 17 provides a guide for the Y-shaped support rod 7, so that the Y-shaped support rod 7 will not deviate or tilt when squeezing the stretch spring 19, and the stretch spring 19 will not be deformed.

[0053] See also Figure 2-Figure 7 A plurality of arc plates 11 are fixedly mounted on the outer wall of the bracket 5, each arc plate 11 corresponds to a circular fixed plate 18, a slider 20 is fixedly mounted on the top of the circular fixed plate 18, an arc groove 14 is formed on the arc plate 11, an arc slide bar 15 is fixedly mounted on the inner wall of the arc groove 14, the slider 20 is slidably connected to the arc slide bar 15, and the slider 20 extends to the inside of the arc groove 14.

[0054] When the tillage disc 6 encounters an obstacle such as a stone, since both sides of the tillage disc 6 are smooth, the tillage disc 6 can tilt and bypass the stone after hitting the stone, or when encountering an inclined ground, the tillage disc 6 can also tilt to get close to the ground. If the tillage disc 6 tilts, the slider 20 will slide left and right along the outer wall of the arc-shaped slide rod 15 and the arc-shaped groove 14 to adapt to the left and right tilt angle of the tillage disc 6;

[0055] Since the movement trajectory of the tillage disc 6 is arc-shaped when it tilts, in order to avoid movement conflicts and adapt to the swinging trajectory of the tillage disc 6, the arc plate 11, the arc groove 14 and the arc slide rod 15 are all arc-shaped in shape, so that the sliding trajectory of the slider 20 can correspond to the tillage disc 6, so that the tillage disc 6 can swing left and right according to the road conditions.

[0056] See also Figure 4 and Figure 7 Two return springs 16 are fixedly connected between the outer wall of the slider 20 and the inner wall of the arc groove 14. The arc slide bar 15 is located inside the return spring 16. The slider 20 is provided with a socket 21, and the arc slide bar 15 is slidably connected to the socket 21.

[0057] The slider 20 is mounted on the arc-shaped slide rod 15 through the insertion hole 21, so the slider 20 can slide along the arc-shaped slide rod 15 through the insertion hole 21. The return spring 16 is used to squeeze the slider 20 to prevent it from easily deviating during the soil-breaking process of the tilling disc 6. The return spring 16 applies pressure to the slider 20, so that the slider 20 will not easily slide along the arc-shaped slide rod 15. When obstacles such as stones appear, the tilling disc 6 will be resisted and the slider 20 will swing, and the movement of the slider 20 will squeeze the return spring 16, so the return spring 16 will not affect the sliding of the slider 20.

[0058] See also Figure 2-Figure 6 A V-shaped pressing plate 13 is provided under each group of tillage discs 8 , and the two tillage discs 8 in each group are fixedly mounted on the top of the V-shaped pressing plate 13 .

[0059] The V-shaped pressing plate 13 makes the bottom of the two tillage plates 8 contacting the ground flat. Therefore, after the tillage plates 8 gather the soil on both sides of the gully, the V-shaped pressing plate 13 can pass over the soil, flatten the soil and press it. Pressing the soil can make the soil particles more tightly combined, reduce the soil porosity, prevent the soil around the seeds from loosening, and is beneficial to the fixation of the seeds and the growth of the root system.

[0060] Working principle:

[0061] During the driving process of the sowing and covering soil equipment body 1, multiple groups of tillage discs 6 are used to break the soil. The contacting side of the two tillage discs 6 of each group breaks the soil to form gullies, and then the seeds will enter the gullies. After the soil forms gullies, the soil will pile up on both sides of the tillage disc 6. The tillage disc 8 is larger than the tillage disc 6, so the piled soil will enter the two tillage discs 8 of each group;

[0062] The openings of the two tillage plates 8 are large so that the soil accumulated on both sides of the gully can enter between the two tillage plates 8. Then, as the tillage plates 8 move, the soil gradually approaches the position where the two tillage plates 8 are close to each other, and is then pushed together by the tillage plates 8, and finally squeezed by the position where the two tillage plates 8 are closest to each other. Finally, the tillage plates 8 pass over the soil and press the soil.

[0063] The bracket 5 supports a plurality of tension springs 19 on one side of the main body 1 of the sowing and covering equipment. The tension springs 19 continuously squeeze the Y-shaped support rod 7 and the tillage plate 6, so that the tillage plate 6 is close to the ground, so that each set of tillage plates 6 can adjust their own distance according to the different depths of the land.

[0064] The tension spring 19 and the Y-shaped support rod 7 are both inclined, so the extrusion of the tillage disc 6 is downward and forward, so that the force of the tillage disc 6 against the ground can be transmitted to the tension spring 19 and the bracket 5, so that this force is brought to the sowing and covering equipment body 1 through the bracket 5, avoiding the tension spring 19 from deforming to the side;

[0065] After the downward depth of the tillage plate 6 changes, the tillage plate 8 will move along with the tillage plate 6, so the tillage plate 8 can cover each gully with soil separately, and will not be affected by the uneven ground. Moreover, the tillage plate 8 gathers the broken soil toward the inside of the gully instead of directly pressing on the soil, so the soil will not be compacted on both sides of the gully.

[0066] The combination of the two tillage discs 6 facilitates breaking the soil, and then the soil will be pushed to one side of the two tillage discs 6. The openings of the two tillage discs 8 are larger than the tillage discs 6, so that the soil accumulated on both sides of each set of tillage discs 6 can enter between the two tillage discs 8;

[0067] As the tillage disc 8 moves, the soil gradually approaches the position where the two tillage discs 8 are close to each other, and is then pushed together by the tillage discs 8, and finally squeezed by the position where the two tillage discs 8 are closest to each other. Finally, the tillage disc 8 passes over the soil and presses the soil. Pressing the soil can make the seeds contact the soil more closely, which is beneficial for the seeds to absorb moisture and nutrients in the soil and improve the germination rate and growth rate of the seeds.

[0068] When the tillage disc 6 encounters an obstacle such as a stone, since both sides of the tillage disc 6 are smooth, the tillage disc 6 can tilt and bypass the stone after hitting the stone, or when encountering an inclined ground, the tillage disc 6 can also tilt to get close to the ground. If the tillage disc 6 tilts, the slider 20 will slide left and right along the outer wall of the arc-shaped slide rod 15 and the arc-shaped groove 14 to adapt to the left and right tilt angle of the tillage disc 6;

[0069] Since the movement trajectory of the tillage disc 6 is arc-shaped when it tilts, in order to avoid movement conflicts and adapt to the swinging trajectory of the tillage disc 6, the arc plate 11, the arc groove 14 and the arc slide rod 15 are all arc-shaped in shape, so that the sliding trajectory of the slider 20 can correspond to the tillage disc 6, so that the tillage disc 6 can swing left and right according to the road conditions.
