Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an integrated seedling strip cleaning and sowing machine. Background Technology

[0002] Conservation tillage is a tillage technology system centered on returning crop straw to the field as mulch. It can effectively reduce wind and water erosion, improve soil fertility and moisture retention, and enhance agricultural ecological and economic benefits. Currently, the technical routes for overcoming the challenges of sowing under straw mulch conditions are mostly based on the operation of straw return machines + no-till seeders and straw row return machines + no-till seeders. The currently used straw processing machinery has two major problems: first, incomplete straw row return, with straw residue remaining in the seedbed causing straw piles in the furrow opener, affecting operations; second, the frequent entry of machinery into the field exacerbates soil compaction and reduces sowing quality. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0004] Therefore, one objective of this utility model is to propose an integrated seedling strip cleaning and sowing machine to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides an integrated seedling strip cleaning and sowing machine, including a machine body, a suspension frame, and a sowing device, as well as a straw cutting device and a straw removal mechanism. The suspension frame is installed at the front upper part of the machine body, the straw cutting device is installed at the front lower part of the machine body, and the straw removal mechanism is installed on the machine body and located on both sides behind the straw cutting device. The sowing device is connected to the rear of the machine body through a four-bar linkage mechanism.

[0006] Furthermore, the straw cutting device is a notched disc cutter, comprising several arcuate sections, with a notch structure between adjacent arcuate sections. The arcuate sections of the notched disc cutter are equipped with cutting edges, and the notch structure is used to collect straw.

[0007] Furthermore, the notched disc cutter adopts a passive rotation design, relying on soil resistance to drive the rotation.

[0008] Furthermore, the straw separating mechanism is an arc-shaped spring-tooth disc, and one straw cutting device is provided with two straw separating mechanisms. The two straw separating mechanisms are inclined and arranged symmetrically in a figure-eight shape, with the front narrower and the back wider in the horizontal direction.

[0009] Furthermore, the arc-shaped toothed disc has an outward tilting structure in the vertical direction, and is narrower at the bottom and wider at the top in the vertical direction.

[0010] Furthermore, the spring teeth of the two curved spring-tooth disks are arranged in an alternating pattern.

[0011] Furthermore, the four-bar linkage connects the machine body and the seeder. The four-bar linkage includes a front plate and a rear plate. The front plate is fixed to the machine body, and the rear plate is connected to the seeder. The front plate and the rear plate are connected by four bars.

[0012] Furthermore, the cutting path of the straw cutting device is longitudinally aligned with the furrowing path of the seeder in the seedling zone.

[0013] Furthermore, the straw-dispersing mechanism scatters the straw in the direction of the outer edge of the seedling strip.

[0014] Furthermore, the machine body integrates and connects the straw separating mechanism, the straw cutting device, the four-bar linkage mechanism, and the seeder to form a single operation unit, and the seeder includes several single operation units arranged side by side.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0016] This utility model discloses an integrated seedling strip cleaning seeder. By integrating a straw cutting device and a straw removal device into the original seeder (seeder), it effectively solves the problems of seeding blockage and reduced operation quality caused by incomplete straw removal in seedling strips due to large straw coverage, limited row width, and uneven ground surface. At the same time, it overcomes the shortcomings of the existing technical route (straw return machine / row return machine + no-till seeder segmented operation), which requires multiple field entries, resulting in increased soil compaction, high power consumption, and high operating costs. The seeder of this utility model can complete straw cutting, removal, row return, and sowing in one operation, significantly improving the cleanliness of the seedling strip, ensuring the operation quality of the seeder under straw-free conditions, reducing operation links and the number of times the machine enters the field, thereby reducing operating costs, improving efficiency, and reducing soil compaction. It meets the needs of efficient and simplified conservation tillage, achieves cost reduction and income increase, and promotes the smooth implementation of the technology.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] like Figures 1-10 As shown, this utility model provides an integrated seedling strip cleaning and sowing machine, including a machine body 3, a suspension frame 4, and a sowing device 6. It also includes a straw cutting device 2 and a straw removal mechanism 1. The suspension frame 4 is installed on the upper front of the machine body 3, the straw cutting device 2 is installed on the lower front of the machine body 3, and the straw removal mechanism 1 is installed on the machine body 3 and located on both sides behind the straw cutting device 2. The sowing device 6 is connected to the rear of the machine body 3 through a four-bar linkage 5.

[0033] This utility model discloses an integrated seedling strip cleaning seeder. By integrating a straw cutting device 2 and a straw removal device into the original seeder (seeder 6), it effectively solves the problems of seeding blockage and reduced operation quality caused by incomplete straw removal in seedling strips due to large straw coverage, limited row width, and uneven ground surface. At the same time, it overcomes the shortcomings of the existing technical route (straw return machine / row return machine + no-till seeder segmented operation), which requires multiple field visits, resulting in increased soil compaction, high power consumption, and high operating costs. The seeder of this utility model can complete straw cutting, removal, row return, and sowing in one operation, significantly improving the cleanliness of the seedling strip, ensuring the operation quality of the seeder under straw-free conditions, reducing operation links and the number of times the machine enters the field, thereby reducing operating costs, improving efficiency, and reducing soil compaction. It meets the needs of efficient and simplified conservation tillage, achieves cost reduction and income increase, and promotes the smooth implementation of the technology.

[0034] Furthermore, such as Figure 5 As shown, the straw cutting device 2 is a notched disc blade, including several arc sections 7, with a notch structure 8 between adjacent arc sections 7. The arc sections 7 of the notched disc blade are equipped with cutting edges 9, and the notch structure 8 is used to collect straw.

[0035] Understandably, the notch structure 8 of the notched disc blade actively collects straw to the cutting edge as it moves forward, while the arc-shaped cutting edge 9 passively rotates and cuts under soil resistance. Compared to traditional straight-bladed blades, this method is more labor-saving and particularly suitable for uneven terrain, thus solving the problem of reduced sowing quality caused by incomplete straw collection.

[0036] Furthermore, the notched disc cutter adopts a passive rotation design, relying on soil resistance to drive the rotation.

[0037] Furthermore, the straw separating mechanism 1 is an arc-shaped spring toothed disc, and one straw cutting device 2 is provided with two straw separating mechanisms 1. The two straw separating mechanisms 1 are inclined and arranged symmetrically in a figure-eight shape, with the front narrower and the back wider in the horizontal direction.

[0038] Understandably, the figure-eight layout of the curved, toothed disc forms an outward-spreading channel. When the toothed disc rotates, it guides the cut straw along the curved surface to the outside of the seedling strip, thus preventing residual straw in the seedling strip from affecting the ditching process.

[0039] Furthermore, such as Figure 4 As shown, the arc-shaped toothed disc has an outward tilting structure in the vertical direction, and is wider at the bottom and narrower at the top in the vertical direction.

[0040] Understandably, the vertical outward tilting structure of the curved, toothed disc allows the lower part of the disc to adhere closely to the soil, expanding the working width and enhancing the ability to grasp straw. It maintains stable contact, especially at elevation differences on raised ridges, eliminating the defect of uneven ground causing failure in straw tracing.

[0041] Furthermore, the spring teeth of the two curved spring-tooth disks are arranged in an alternating pattern.

[0042] Understandably, the staggered arrangement of the springs ensures that the surface sweeping area overlaps 100%, leaving no blind spots and achieving full coverage of the seedling strip. This prevents any missed straw from falling back into the sowing path and ensures consistent sowing and furrowing depth in subsequent planting.

[0043] Furthermore, the four-bar linkage 5 connects the machine body 3 and the seeder. The four-bar linkage 5 includes a front plate 10 and a rear plate 11. The front plate 10 is fixed on the machine body 3, and the rear plate 11 is connected to the seeder 6. The front plate 10 and the rear plate 11 are connected by four rods 12.

[0044] like Figure 6 , Figure 7 and Figure 8 As shown, the four-bar linkage mainly consists of a four-bar front end plate 10, a four-bar rear end plate 11, a four-bar plate 12, a pin 13, and a pin nut 14.

[0045] The four-bar front end plate 10 is fixed on the frame, the four-bar rear end plate 11 is connected to the seeder 6, the four-bar plate 12 is connected between the four-bar front end plate 10 and the four-bar rear end plate 11 through the pin 13, and the pin nut 14 fixes the axial displacement of the pin 13.

[0046] During operation, the front end plate 10 of the four rods is fixed to the frame, and the rear end plate 11 of the four rods is rigidly connected to the seeder 6 unit. When the seeder 6 unit moves with the undulation of the ground, the four rod plate 12 rotates around the pin 13, and the rear end plate 11 of the four rods drives the seeder 6 unit to move up and down only in the vertical direction, thus completing the contouring function of the seeder 6 unit in the vertical direction.

[0047] Furthermore, the cutting path of the straw cutting device 2 and the furrowing path of the seeder 6 are longitudinally aligned in the seedling area.

[0048] Aligning the cutting and sowing paths longitudinally enables process coordination and ensures that the cleaned area completely covers the sowing operation zone.

[0049] Furthermore, the straw-dispersing mechanism 1 is scattering in the direction of the outer side of the seedling strip.

[0050] The straw-removing mechanism 1 limits the direction of scattering to the outside of the seedling strip, and works with the figure-eight structure to form a forced guide to prevent the straw from bouncing back.

[0051] Furthermore, the machine body 3 integrates and connects the straw separating mechanism 1, the straw cutting device 2, the four-bar linkage mechanism 5, and the seeder 6 to form a single operation unit, and the seeder includes several single operation units arranged side by side.

[0052] like Figure 1 As shown, in one embodiment, a seeder has four single-operation units, meaning it can simultaneously sow seeds on four ridges, greatly improving operational efficiency.

[0053] In one embodiment, such as Figure 9 and Figure 10 As shown, it also includes structures such as an upper suspension 15, a lower suspension 16, a support arm 17, a suspension beam 18, a seed metering device 19, a seed chamber 20, a fertilizer support 21, a soil covering mechanism 22, a soil covering wheel 23, a seed pressing wheel 24, a seed guide tube 25, a seed pressing wheel adjustment mechanism 26, a seed furrow guard plate 27, and a seed furrow opening shovel 28. Among them, the upper suspension 15 is used to connect to the tractor lifting arm and control the lifting of the whole machine; the lower suspension 16 is fixed to the tractor's lower lever and transmits traction force; the support arm 17 is used to connect and install the straw cutting device 2; and the suspension beam 18 is the main frame for installing the working unit, bearing the working parts and metering seeds. The device 19 is used to control seed dispensing, the seed chamber 20 is used to store seeds to ensure continuous seed supply, the fertilizer holder 21 is used to fix the fertilizer application device to achieve simultaneous seed and fertilizer application, the soil covering mechanism 22 is used to cover the seed furrow with soil after sowing, the soil covering wheel 23 rotates to dispose of soil to complete the seed furrow covering, the seed pressing wheel 24 compacts the soil in the seed furrow to ensure that the seeds are in contact with the soil moisture, the seed guide tube 25 guides the seeds to fall accurately from the seed metering device 19 into the seed furrow, the seed pressing wheel adjustment mechanism 26 can control the seed pressing force through spring or hydraulic pressure, the seed furrow opening shovel 28 breaks the soil to open the sowing furrow, and the seed furrow guard plate 27 prevents the seed furrow from collapsing and maintains the shape of the furrow.

[0054] Since this application is an improvement on the original seeder (seeder 6) by integrating the straw cutting device 2 and the straw separating device, and the seeder 6 is an existing mature machine, its specific structure and connection method will not be described in detail here.

[0055] Working Principle: This utility model implement is mounted on the rear three-point suspension of a tractor via a suspension frame 4, and is pulled forward by the tractor to complete the operation. The tractor controls the forward and vertical position of the machine body 3 through the suspension frame 4. The straw cutting device 2 and the straw separating mechanism 1 are mounted on the machine body 3, thus realizing its working drive. The straw cutting device 2 is a notched disc structure. During operation, the arc part 7 of the blade enters the soil, and the soil provides significant resistance, driving it to rotate passively. The notch design facilitates the collection of straw at the cutting point by the disc blade, and the cutting part of the disc blade has a cutting edge 9. When the implement moves forward, the disc blade and the straw in the notch form a speed difference with the soil. The straw, supported by the soil, is cut by the cutting edge 9 of the disc blade that has entered the soil, achieving labor-saving straw cutting. The straw removal mechanism 1, installed on both sides behind the straw cutting device 2, adopts an arc-shaped, finger-type disc structure. This design improves the stubble removal effect. The finger-type discs are arranged on both sides behind the straw cutting device 2, in contact with the soil. When the machine moves, the soil resistance drives the discs to rotate. They are arranged at an angle, with two wheels in a figure-eight shape. Horizontally, they are narrower at the front and wider at the back, with staggered spring teeth to ensure overlap of the teeth across the ground. Vertically, they are also outward-sloping, narrower at the bottom and wider at the top. This arrangement ensures that the straw cut by the straw cutting device 2 is effectively thrown out of the seedling belt, guaranteeing a clean seedling belt. The seeder 6 is installed behind the machine body 3 via a four-bar linkage 5. The four-bar linkage 5's contour-following action ensures effective contact between the machine and the soil. This design allows the seeder 6 to work on a clean seedling belt, eliminating the impact of straw on the seeder and ensuring the quality of the seeder's operation.

[0056] This utility model relates to an integrated seedling strip cleaning and seeding machine, designed to solve the problem of straw blockage and reduced work quality during conservation tillage due to the large amount of straw cover, limited row width, and incomplete straw removal from the seedling strips. The design adds a straw cutting device and a straw separating device to the existing corn seeder, effectively cutting and separating the straw from the corn seedling strips, ensuring cleanliness, creating favorable conditions for subsequent sowing operations, meeting the needs of efficient and simplified conservation tillage, achieving cost reduction and increased income, and promoting the smooth implementation of this technology.

[0057] Currently, the technical approaches to overcome the challenges of sowing under straw mulch conditions are mostly based on the combination of straw return machine and no-till seeder, or straw row return machine and no-till seeder. These operational methods suffer from problems such as numerous machine operations, poor work quality, high power consumption, and high operating costs.

[0058] This invention addresses the problem of straw congestion during seeding operations caused by poor straw crushing and row-gathering due to factors such as large straw coverage, limited row width, and uneven ground surfaces like furrows and ridges. Furthermore, this invention enables the machine to complete straw cutting, row-gathering, and sowing in a single operation, reducing operational steps, lowering operating costs, improving efficiency, and reducing soil compaction.

[0059] This machine has a reasonable structure, stable operation, multiple functions, convenient maintenance, and produces neat and clear rows of straw and seedlings, resulting in significant operational benefits. It meets the needs of efficient and simplified conservation tillage, achieving cost savings and increased income, and promoting the smooth implementation of conservation tillage technology.
