Description

Technical Field

[0001] This invention relates to the field of corn planting technology, specifically to a precision seeding machine for corn triangular high-density planting with no-till fertilization. Background Technology

[0002] A corn planter is a planting machine that sows corn seeds. With the development of agricultural technology, there are now corn planters that can simultaneously fertilize and lay drip irrigation tape. However, during use, obstacles such as stubble and weeds on the land will accumulate at the furrow opener, affecting the sowing effect.

[0003] To increase yield, an innovative corn planting method was proposed. This method is based on uniform single-row planting with equal row spacing. In uniform single-row planting, the plants are evenly arranged. The reasonable staggered planting or triangular seedling method involves evenly moving the corn plants in the single row to both sides of the original plant, forming small double rows. It also changes the previous random arrangement of plants between adjacent rows. The staggered planting method makes the plants in adjacent rows staggered, forming a seed arrangement similar to an isosceles triangle or a triangle. The reasonable staggered planting or triangular seedling method significantly increases the plant spacing within the row and makes the plants in the row staggered, effectively improving the ventilation and light conditions between plants.

[0004] Currently, there are triangular dense planting seeders that use a single-sided finger clamp seed metering device. However, when this type of seeder is sowing, the single-sided finger clamp seed metering device is driven by a transmission mechanism consisting of a ground wheel and a gearbox. The ground wheel, as the power source, has relatively high requirements for sowing speed and the flatness of the sowing surface. At the same time, the seeds discharged by the single-sided finger clamp seed metering device need to pass through a curved seed metering tube to fall onto the soil. In actual planting operations, this can easily cause the seed planting position to shift, thus affecting the staggered dense planting effect. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a precision seeding machine for triangular dense planting of maize, featuring no-till fertilization.

[0043] As Figures 1-5As shown, a precision dibbling type no-tillage fertilizing precision seeder for corn triangular dense planting cultivation is provided, comprising a rack A, a profiling seeding unit B and a roller C, at least two profiling seeding units B are uniformly arranged on one side of the rack A, a fertilizing mechanism D connected with the rack A is arranged in front of each profiling seeding unit B in the seeding direction, and a roller C connected with the rack A is arranged behind each profiling seeding unit B in the seeding direction, the profiling seeding unit B comprises a hole seeder B1, a coaxial connecting shaft B2 and a connecting rod B3, two hole seeders B1 are arranged in mirror symmetry and coaxially on the coaxial connecting shaft B2, the two hole seeders B1 have a radial deflection angle therebetween and are connected into one body through at least two connecting pieces B4 arranged circumferentially between the two hole seeders B1, and the two ends of the coaxial connecting shaft B2 are fixedly connected with one end of the two connecting rods B3, respectively, and the other end of the two connecting rods B3 is fixedly connected with the rack A, and the two hole seeders B1 connected into one body on the coaxial connecting shaft B2 are simultaneously rolled on the ground under the driving of the rack A, so that the seeds discharged from the two hole seeders B1 have an equal sequence displacement difference; the two hole seeders B1 are used in cooperation, and the seeds discharged from the two hole seeders B1 have an equal sequence displacement difference through a reasonable installation mode, so that the profiling seeding unit B having a triangular dense planting seed sowing function is formed, and the seeder having a multi-row planting function is formed through the cooperation between the multiple profiling seeding units B, the fertilizing mechanism D and the roller C, the planting precision characteristic of the hole seeder B1 is utilized, the seed deviation amount during sowing is reduced, and the staggered dense planting effect is ensured.

[0044] Wherein: the profiling seeding unit B and the rack A are detachably connected through a connecting part for adjusting the spacing between the profiling seeding units B, and the connecting part can adopt a U-shaped bolt or a U-shaped plate, so that the spacing between the profiling seeding units B can be changed according to the local environment of the planting site, so as to change the planting row spacing, specifically 60CM, 70CM, 80CM, 90CM, etc., and the center row spacing is preferably 75CM.

[0045] Wherein, the fertilizing path of the fertilizing mechanism D coincides with the symmetry axis M of the two hole seeders B1; the fertilizer box D1 and the fertilizer furrow opener D2 are arranged on the rack A, one end of the fertilizer guide pipe communicates with the fertilizer box D1, the other end of the fertilizer guide pipe communicates with the near-ground end of the fertilizer guide pipe, the fertilizer in the fertilizer box D1 falls behind the fertilizer furrow opener D2 through the fertilizer guide pipe to form a fertilizing path on the ground, and since the fertilizing path coincides with the symmetry axis M of the two hole seeders B1, the fertilizer is between the small double rows of corn, and the fertilizing operation of two rows of corn can be completed through one fertilizer furrow opener D2 and one fertilizer guide pipe; wherein, the way and amount of the fertilizer in the fertilizer box D1 entering the fertilizer guide pipe are both prior art, and will not be described here.

[0046] The hole seeder B1 can be any hole seeder B1 with hole seeding function in the prior art, preferably the hole seeder B1 disclosed in the authorized announcement No. CN209184996U.

[0047] The number of finger clamping spoons in the hole seeder B1 is at least two, specifically 2, 4, 5, 6, 7, 8, 9, 10, 12, 13, 18, 20, etc. The radial deflection angle between the two hole seeders B1 changes according to the number of finger clamping spoons (the number of duck bills B11 in the hole seeder B1 for sowing seeds into the soil is the same as the number of finger clamping spoons). The radial deflection angle is the quotient of the central angle and the total number of finger clamping spoons in the two hole seeders B1. When the number of each finger clamping spoon is 12, the total number of two finger clamping spoons is 24, and the radial deflection angle is 15° (360° / 24=15°). Therefore, when the number of each finger clamping spoon is 5, the radial deflection angle is 36°, and when the number of each finger clamping spoon is 2, the radial deflection angle is 90°. According to the number of finger clamping spoons in the hole seeder B1, the radial deflection angle between the two hole seeders B1 is adjusted. The seed box B5 is fixed on the connecting rod B3 and is located on the upper side of the hole seeder B1. The seeds in the seed box B5 enter the hole seeder B1 through the seed discharge pipe. When the two hole seeders B1 directly contact the ground and rotate around the coaxial connecting shaft B2 at the same time, the seeds discharged from the two hole seeders B1 have an equal sequence displacement difference, so that the plants between adjacent rows are staggered, forming a seed arrangement mode similar to an isosceles triangle or a triangle. At the same time, the plant spacing within the same row is changed to achieve fine adjustment of the planting density.

[0048] The connecting piece B4 includes a connecting bolt B41 and a support cylinder B42. The connecting bolt B41 penetrates the fixing plates of the two hole seeders B1 in sequence and connects the two hole seeders B1. The support cylinder B42 is sleeved on the connecting bolt B41 between the two hole seeders B1. The two hole seeders B1 are connected as a whole through the connecting piece B4 formed by the connecting bolt B41 and the support cylinder B42, which is convenient for simultaneous rotation and ensures the stability of the radial deflection angle between the two hole seeders B1. At the same time, the support cylinder B42 is arranged between the two hole seeders B1 to support the two hole seeders B1, so that the spacing between the two hole seeders B1 remains stable, improving the stability of the double-row staggered dense planting. The size of the support cylinder B42 can be changed to adjust the spacing between the two hole seeders B1, so that the spacing between the small double rows can be adjusted according to different planting topography. The bolt connection realizes detachable connection, which is convenient for quick disassembly and assembly. Embodiment

[0049] As Figure 5As shown in the figure, the embodiment is obtained by changing the connection mode of the rack A and the hill-drop device B1 and other technical features on the basis of embodiment one, and the remaining technical features are the same as those of embodiment one, and the same parts are not described here. The difference between this embodiment and embodiment one is that the other end of the connecting rod B3 is hinged to the rack A, and the connecting rod B3 and the rack A are respectively hinged to one end of the damping compression spring B6.

[0050] The connecting rod B3 and the rack A are respectively hinged to one end of the damping compression spring B6, the damping compression spring B6 is on the upper side of the connecting rod B3, so that the connecting rod B3, the rack A and the damping compression spring B6 form a triangular structure, which ensures the stability of the connection and enables the hill-drop device B1 to be in contact with the ground at all times under the action of the damping compression spring B6, thereby ensuring that the duckbill B11 of the hill-drop device B1 can be inserted into the soil for seeding operation. When encountering uneven ground, the hill-drop device B1 can move according to the flatness of the ground under the action of the damping compression spring B6, thereby realizing seeding operation on uneven ground. Embodiment

[0051] As shown in the figure, the embodiment is obtained by changing the connection mode of the rack A and the hill-drop device B1 and other technical features on the basis of embodiment one, and the remaining technical features are the same as those of embodiment one, and the same parts are not described here. The difference between this embodiment and embodiment one is that the other end of the connecting rod B3 is hinged to the rack A, and the connecting rod B3 and the rack A are respectively hinged to one end of the damping compression spring B6. Figures 2-4 and Figure 6 As shown in the figure, the embodiment is obtained by changing the connection mode of the rack A and the hill-drop device B1 and other technical features on the basis of embodiment one, and the remaining technical features are the same as those of embodiment one, and the same parts are not described here. The difference between this embodiment and embodiment one is that the other end of the connecting rod B3 is hinged to the rack A, and the connecting rod B3 and the rack A are respectively hinged to one end of the damping compression spring B6.

[0052] In the embodiment, the obstacle-removing rotary tiller group E includes rotary tiller blades E3 and rotary tiller discs E4, the rotating shaft E2 is a prismatic structure, at least two rotary tiller discs E4 are sleeved on the rotating shaft E2 and are detachably connected through fixing components that can adjust the spacing between the rotary tiller discs E4, the fixing components can be pins penetrating through the rotary tiller discs E4 and the rotating shaft E2 or screws penetrating through the rotary tiller discs E4 and being tightly arranged on the rotating shaft E2 to limit the axial movement of the rotary tiller discs E4 on the rotating shaft E2, at least two rotary tiller blades E3 are uniformly arranged on the rotary tiller disc E4 in the circumferential direction, and at least two rotary tiller discs E4 are arranged on the rotating shaft E2 in the radial direction and are symmetrically arranged, and the bending direction of the end of the rotary tiller blade E3 is opposite to the axis of symmetry. When the rotating shaft E2 drives the obstacle-removing rotary tiller group E to rotate, each rotary tiller blade rotates the soil in the region and directs the obstacles and part of the soil to the outside, forming a rotary tillage obstacle-removing region in the form of a trench behind each obstacle-removing rotary tiller group E in the rotary tillage direction. The trench can quickly drain water to prevent waterlogging when there is much water, and can collect rainwater and dew to resist drought when it is dry. A plurality of obstacle-removing rotary tiller groups E are arranged on the rotating shaft E2 at intervals, and the obstacle-removing rotary tiller group E corresponds to the fertilizer mechanism D and the profiled seeding unit B in front and back, so that the fertilizer and seeds are in the rotary tillage obstacle-removing region in the form of a trench, and the corn is planted in the trench with low middle and high sides, which can effectively resist lodging and reduce losses in windy weather. The soil after rotary tillage is convenient for the duck bill B11 of the hole seeder B1 to insert into the soil for seeding operation.

[0053] In the embodiment, the depth-limiting wheels H can be arranged on the frames A on both sides of the obstacle-removing rotary tiller group E through the height adjustment assembly G (the height adjustment device F4 is one of a pneumatic telescopic rod, a hydraulic telescopic rod, an electric push rod, a manual push rod, and a shock-absorbing compression spring B6). The height of the frame A at the obstacle-removing rotary tiller group E is adjusted through the height adjustment device F4, so as to control the rotary tillage depth of the obstacle-removing rotary tiller group E. Embodiment

[0054] As shown in Figure 3 and Figure 4 , the embodiment is obtained by increasing the connecting mode of the adjustable leveling and compacting wheel F3 and other technical features on the basis of embodiment three. The remaining technical features are the same as those of embodiment three, and the same parts will not be described here. The difference between the embodiment and embodiment three is that the adjustable leveling and compacting wheel F3 for leveling and compacting the rotary tillage obstacle-removing region is arranged on the frame A between each group of profiled seeding unit B and fertilizer mechanism D in front and back, and the adjustable leveling and compacting wheel F3 is arranged on the frame A through the height adjustment device F4.

[0055] The adjustable leveling and compacting roller F3 is connected to the frame A via a height adjustment device F4 (the height adjustment device F4 is one of a pneumatic telescopic rod, hydraulic telescopic rod, electric push rod, manual push rod, or shock-absorbing spring B6). The height adjustment device F4 is preferably a manual push rod, and the manual push rods are connected by a coupling to form a linkage between multiple manual push rods. When the operator rotates the handle F5, multiple height adjustment devices F4 can be adjusted simultaneously, saving time and effort. By adjusting the length of the height adjustment device F4, the pressure of the adjustable leveling and compacting roller F3 on the ground can be adjusted. It can level and compact the uneven areas in the rotary tillage clearing area and the uneven areas formed by the fertilizer furrow opener D2 after fertilization, increasing the density and flatness of the soil after rotary tillage, which is convenient for subsequent seed implantation and drip irrigation tape laying. Example

[0056] like Figures 1-4 As shown, this embodiment is obtained by adding technical features such as the drip irrigation tape laying device F to the connection method based on embodiment four. The other technical features are the same as those in embodiment four, and the similarities will not be repeated here. The difference between this embodiment and embodiment four is that the drip irrigation tape laying device F is provided on the frame A between the corresponding front and rear contour seeding unit B and the adjustable leveling and pressing wheel F3 in each group, so that the laying path of the drip irrigation tape coincides with the symmetrical axis M of the two seeders B1.

[0057] In this embodiment, the drip irrigation tape laying device F includes a drip irrigation tape mounting frame F1 and a drip irrigation tape trenching and laying device F2. The drip irrigation tape trenching and laying device F2 forms a groove in the ground. The drip irrigation tape wrapped around the drip irrigation tape mounting frame F1 passes between the back of the drip irrigation tape trenching and laying device F2 and the ground. The drip irrigation tape passes through the symmetrical axis M of the two seeders B1 and the pressing wheel C, so that the drip irrigation tape is laid on the ground. At the same time, the middle part of the pressing wheel C is concave inward to form an inner concave part C1. The drip irrigation tape passes through the inner concave part C1. When the pressing wheel C performs the pressing operation, it can push the soil on both sides onto the drip irrigation tape, covering the drip irrigation tape with an intermittent thin layer of soil to prevent the drip irrigation tape from being blown away by the wind. At the same time, the intermittent coverage of the thin layer of soil reduces the pressure of the soil layer on the drip irrigation tape and prevents the drip irrigation tape from being obstructed due to excessive pressure.

[0058] The laying path of the drip irrigation tape coincides with the axis of symmetry M of the two seeders B1, so that the drip irrigation tape is placed between the small double rows of corn. The two rows of corn can be irrigated at the same time through one drip irrigation tape. In conjunction with the trench formed by the above-mentioned clearing rotary tillage blade group E, the irrigation water usage is reduced.

[0059] Through the combination of the above embodiments, a seeder with the functions of rotary tillage and obstacle removal, drip irrigation tape laying and fertilization is formed, the planting row spacing is adjusted according to the planting environment, the small double-row staggered seeding is realized, and the seeder can complete a series of processes of ridge cleaning and ditching, fertilization, seeding, pressing and shallowly buried drip irrigation tape laying at one time, so that the seeding process is efficient and time-saving and labor-saving.

[0060] In use, the frame A is moved by the traction mechanism and provides power for the rotary tillage gearbox E1, in the moving process, the obstacle-removing rotary tillage cutter group E rotates and forms a rotary tillage and obstacle-removing area behind the moving direction, the fertilization mechanism D fertilizes on the rotary tillage and obstacle-removing area and forms a fertilization path, the drip irrigation tape laying device F lays drip irrigation on the rotary tillage and obstacle-removing area and forms a drip irrigation laying path, the two seeders B1 are directly in contact with the ground and rotate around the coaxial connecting shaft B2 at the same time, the seeds are discharged from the duckbills B11 of the two seeders B1, the discharged seeds are in the shape of isosceles triangle on the ground and are buried in the soil layer, two seeding paths are formed on the rotary tillage and obstacle-removing area, the central axis of the rotary tillage and obstacle-removing area, the fertilization path, the drip irrigation laying path and the symmetry axis M of the two seeding paths coincide, and finally the two seeding paths are pressed by the press wheel C, a series of processes of ridge cleaning and ditching, fertilization, shallowly buried drip irrigation tape laying, seeding and pressing are completed at one time.

[0061] Note that the above are only the preferred embodiments of the present application and the technical principles applied. Those skilled in the art will understand that the present application is not limited to the specific embodiments herein, and those skilled in the art can make various obvious changes, re-adjustments and substitutions without departing from the scope of the present application.
