Abstract
Description
Technical Field
[0001] The invention relates to the technical field of soil covering, in particular to a soil covering device for sugarcane interplanting with tartary buckwheat. Background Art
[0002] Sowing and covering sugarcane and buckwheat together can significantly improve land utilization rate. The rapid growth of buckwheat can effectively control weeds, improve soil structure and microbial environment, reduce the occurrence of diseases and insect pests, and provide additional short-term economic benefits before the sugarcane matures. This intercropping pattern can also enhance soil biodiversity, promote the activity of beneficial microorganisms, further improve soil fertility, and improve the economic benefits and ecology of agricultural production. Intercropping buckwheat and sugarcane and covering them with soil can effectively keep the soil moist, regulate soil temperature, inhibit weed growth, improve soil structure, and prevent soil erosion, thereby providing a good growth environment for crops and improving the ecological benefits of farmland.
[0003] Sugarcane is planted at intervals of one to two meters, while buckwheat is planted about ten centimeters on both sides of the sugarcane. When covering the soil, the depth of covering the sugarcane and buckwheat seeds is different. Sugarcane seeds require deeper covering, which is usually about 5-10 centimeters, while buckwheat seeds only require shallower covering, which is usually about 2-3 centimeters. This difference makes it difficult for existing covering machines to meet the covering needs of both crops at the same time. Covering the soil too deeply will affect the germination and emergence of buckwheat seeds, while covering the soil too shallowly may expose sugarcane seeds or seed stems, affecting their germination and growth. In addition, the difference in covering the soil will increase the difficulty of field management and reduce the overall planting effect.
[0004] Based on the above situation, the present invention proposes a soil covering device for sugarcane intercropping with tartary buckwheat. Summary of the invention

DETAILED DESCRIPTION
[0030] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.
[0031] Embodiment 1: A soil covering device for intercropping buckwheat with sugarcane, see attached Figure 1 To Attachment Figure 3, including a covering machine body 1, a covering cover 2 is fixedly connected to the lower rear part of the covering machine body 1, a first inclined plate 201 symmetrically distributed along the covering cover 2 is fixedly connected to the inner side of the lower part of the covering cover 2, a second inclined plate 202 symmetrically distributed along the covering cover 2 is fixedly connected to the inner side of the lower part of the covering cover 2, and the second inclined plate 202 is located on the inner side of the first inclined plate 201, a first discharge port 203 is arranged between adjacent second inclined plates 202, the first discharge port 203 corresponds to the sugarcane row, the first discharge port 203 is located in the middle of the covering cover 2, a second discharge port 204 is arranged between adjacent first inclined plates 201 and second inclined plates 202, the second discharge port 204 corresponds to the bitter buckwheat row, and the lower part of the covering cover 2 is rotatably connected to covering knives symmetrically distributed along the covering cover 2 The soil covering blade 3 is located on the outer side of the adjacent first inclined plate 201, four steel wires 4 with equal spacing are fixedly connected between the first inclined plate 201 and the soil covering cover 2, a screen frame 5 is fixedly connected between the adjacent first inclined plate 201 and the second inclined plate 202, the screen frame 5 is located above the adjacent second discharge port 204, the soil covering blade 3 lifts the soil onto the screen frame 5 through a certain angle and rotation action, the screen frame 5 has a plurality of screen holes, and the area of all the solid parts of the screen frame 5 is larger than the area of all the screen holes of the screen frame 5, so that most of the soil flows to the first discharge port 203 through the solid part of the screen frame 5, and a small part of the soil flows to the second discharge port 204 through the screen hole part of the screen frame 5. Specifically, the ratio of the area of the solid part of the screen frame 5 to the area of the screen hole part can be set to five to three.
[0032] First, sugarcane seeds are scattered in the ditch with the middle row falling, and buckwheat seeds are scattered in the ditches on both sides of the sugarcane seeds. Then, the first discharge port 203 of the soil covering machine body 1 is made to correspond to the sugarcane row falling, and the second discharge ports 204 on the left and right sides of the soil covering machine body 1 correspond to the buckwheat rows on the left and right sides respectively. Then, the soil covering machine body 1 is started to rotate the soil covering blade 3. While shoveling up the soil, the soil covering blade 3 lifts the soil onto the screen frame 5 through a certain angle and rotation action. Before reaching the screen frame 5, the soil will pass through a row of steel wires 4. Due to the blocking effect of the spacing between the steel wires 4, stones and other materials in the covering soil are isolated on the outside of the steel wires 4 and roll down along the first inclined plate 201. The solid part area of the screen frame 5 is larger than the screen hole area, so that most of the covering soil falling on the screen frame 5 slides along the screen frame 5 to the middle first discharge port 203 and covers the sugarcane seeds falling in the middle row, and a small part falls through the screen holes of the screen frame 5 to the second discharge ports 204 on both sides and covers the buckwheat seeds falling in the rows on both sides. Specifically, for example, the area ratio of the solid part and the screen hole part of the screen frame 5 can be set to about five to three, so that the ratio of the amount of covering soil in the middle to the amount of covering soil on the sides is ten to three. By adjusting the forward moving speed of the soil covering machine body 1, the soil covering depth of the middle sugarcane row can be controlled to be about ten centimeters, so that the soil covering depth of the buckwheat rows on both sides can be about three centimeters.
[0033] In summary, the present invention controls the diversion of covering soil through the screen frame 5, so that sugarcane seeds get more covering soil and buckwheat seeds get less covering soil, which solves the problem of soil covering difference when intercropping sugarcane with buckwheat, reduces the difficulty of field management, and improves the overall planting effect.
[0034] Example 2: Based on Example 1, see the attached Figure 2 To Attachment Figure 4 , also includes a magnetic frame 6 symmetrically distributed along the front and back of the soil covering cover 2, the magnetic frame 6 is slidably connected to the outer wall of the soil covering cover 2 along the up and down direction, the second inclined plate 202 is slidably connected to the side of the screen frame 5 along the up and down direction with a baffle 601, the front and rear ends of the baffle 601 are respectively fixedly connected to the magnetic frames 6 on the front and rear sides, the outer wall of the soil covering cover 2 is fixedly connected with electromagnets 602 symmetrically distributed along the front and back of the soil covering cover 2, and the electromagnets 602 cooperate with the adjacent magnetic frames 6 through repelling magnetic forces.
[0035] In order to ensure that the covering soil can smoothly roll down to the first discharge port 203, the inclination of the screen frame 5 cannot be too small, and the inclined screen frame 5 may cause the covering soil to quickly roll down to the covering soil position of the sugarcane seeds, so that the covering soil has almost no time to pass through the sieve holes of the screen frame 5 and fall to the covering soil position of the buckwheat seeds on both sides, resulting in insufficient covering soil for the buckwheat seeds and excessive covering soil for the sugarcane seeds. To avoid this situation, the electromagnet 602 can be controlled to be intermittently energized, and the electromagnet 602 pushes the magnetic frame 6 upward through magnetic repulsion. , so that the baffle 601 intermittently extends slightly upward to a certain height, blocking a small amount of soil on the side of the screen frame 5 close to the baffle 601, and piling up to a height flush with the baffle 601. In this way, a small amount of soil is piled up into a gentle small soil slope on the side of the screen frame 5 close to the baffle 601. By setting a gentle slope on the inner side of the screen frame 5, the speed of the screen frame 5 discharging soil to the first discharge port 203 can be slowed down, so that the covering soil has time to pass through the sieve holes of the screen frame 5 and fall into the second discharge ports 204 on both sides.
[0036] In order to prevent large clods of soil and other objects from accumulating on the baffle 601 and affecting the normal soil covering function, it is necessary to control the electromagnet 602 to be intermittently powered off, and the magnetic frame 6 and the baffle 601 move downward and reset under the action of gravity to avoid the accumulation of large clods of soil.
[0037] Example 3: Based on Example 2, see the attached Figure 5 and attached Figure 6, also includes a screw rod 7 symmetrically distributed along the soil covering cover 2, the screw rod 7 is rotatably connected to the top of the outer wall of the soil covering cover 2, a guide frame 8 is threadedly connected to the screw rod 7, the guide frame 8 is slidably connected to the soil covering cover 2, and a guide plate 9 is slidably connected to the bottom of the second inclined plate 202 in an inclined direction, and an inclined groove 901 symmetrically distributed along the soil covering cover 2 is opened at the lower rear side of the soil covering cover 2, and the inclined groove 901 is parallel to the adjacent second inclined plate 202, and two upper and lower slide grooves 902 are opened on the front and rear sides of the lower part of the guide frame 8, and the guide plate 9 is slidably connected to the adjacent lower slide groove 902, and a blocking frame 10 is slidably connected between the adjacent inclined grooves 901 in the inclined direction, and the blocking frame 10 is slidably connected to the adjacent upper slide groove 902, and an adjustment plate 11 is arranged in the middle of the blocking frame 10.
[0038] By limiting the guide plate 9 and the adjusting plate 11, the covering soil passing through the sieve hole can be accurately guided into the ditch of the bitter buckwheat seeds to prevent it from falling out of the ditch. Moreover, when it is necessary to increase the row spacing between the bitter buckwheat rows and the sugarcane rows, the screw rod 7 can be rotated to move the guide frame 8 downward, thereby driving the slide 902 to move downward, thereby pushing the guide plate 9 and the baffle frame 10 to move downward, and the baffle frame 10 drives the adjusting plate 11 to move downward synchronously. Under the guidance of the second inclined plate 202, the guide plate 9 will also move away from the guide plate 9 during the downward movement. The first discharge port 203 moves horizontally to one side, and at the same time, guided by the inclined groove 901, the baffle 10 also moves horizontally to the side away from the first discharge port 203 during the downward movement, thereby driving the adjustment plate 11 to move horizontally to the side away from the first discharge port 203 synchronously, and because the second inclined plate 202 is parallel to the inclined groove 901, the guide plate 9, the baffle 10 and the adjustment plate 11 move synchronously. On the contrary, when it is necessary to reduce the row spacing between the buckwheat rows and the sugarcane rows, the screw 7 can be rotated in the opposite direction.
[0039] Example 4: Based on Example 3, see the attached Figure 7 To Attachment Fig. 9 , and also includes torsion springs 12 symmetrically distributed along the front and back of the adjustment plate 11. The adjustment plate 11 is rotatably connected to the adjacent baffle frame 10. The two ends of the torsion spring 12 are fixedly connected to the adjacent adjustment plate 11 and the baffle frame 10 respectively. The baffle frame 10 is slidably connected with a bracket 13 along the up and down directions. The bracket 13 is squeezed and matched with the outer side surface of the adjacent adjustment plate 11. A load-bearing frame 14 is arranged on the lower side of the bracket 13. The load-bearing frame 14 is located in the middle below the adjacent adjustment plate 11 and the guide plate 9. The middle of the load-bearing frame 14 is arranged in an inverted V shape.
[0040] When the covering soil passing through the sieve holes is smoothly guided out along the guide plate 9, the covering soil will fall on the load-bearing frame 14, causing the load-bearing frame 14 to move downward, thereby driving the bracket 13 to slide downward along the baffle frame 10, and the bracket 13 squeezes the adjustment plate 11 to rotate and embed into the baffle frame 10, and the torsion spring 12 is deformed, so that the covering soil can be accurately guided along the guide plate 9 and the adjustment plate 11 into the ditch for the buckwheat seeds.
[0041] When the covering soil passing through the sieve holes is blocked between the guide plate 9 and the adjusting plate 11 and cannot be smoothly discharged, since almost no covering soil falls on the load-bearing frame 14, the torsion spring 12 is reset to drive the adjusting plate 11 to rotate in the opposite direction, thereby increasing the gap between the guide plate 9 and the adjusting plate 11, so that the covering soil can be loosened and can be discharged into the ditch again, thus achieving the effect of clearing the blocked covering soil. When the adjusting plate 11 rotates in the opposite direction, the squeezing bracket 13 slides upward along the retaining frame 10, thereby driving the load-bearing frame 14 to move upward and reset.
[0042] See attached Fig.10 , and also includes a push plate 15 corresponding to the load-bearing frame 14, the push plate 15 is fixedly connected to the corresponding load-bearing frame 14, the push plate 15 contacts the outer side surface of the adjacent adjustment plate 11, the bracket 13 is slidably connected to the adjacent load-bearing frame 14, and a spring 16 is fixedly connected between the bracket 13 and the adjacent load-bearing frame 14.
[0043] When the adjusting plate 11 is embedded in the blocking frame 10, the load-bearing frame 14 is located in the middle position between the guide plate 9 and the adjusting plate 11. At this time, the spring 16 is in a natural state. When the gap between the guide plate 9 and the adjusting plate 11 increases, it is necessary to readjust the position of the load-bearing frame 14 so that the load-bearing frame 14 is still located in the middle of the guide plate 9 and the adjusting plate 11. Specifically, when the adjusting plate 11 rotates in the opposite direction, the push plate 15 is squeezed to move outward, thereby pulling the load-bearing frame 14 to slide outward along the bracket 13, and the spring 16 is compressed.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
