Novel combined seed and fertilizer drill
Technical Field
[0001] The invention mainly relates to the technical field of agricultural instruments, in particular to a novel combined seed and fertilizer drill.
Background Technology
[0002] Sowing is the first and most important link in grain production. The quality of the seeding machinery directly affects the sowing quality, which is closely related to the yield. Therefore, it is of great significance to develop precise, high efficiency and high quality seeding machinery for increasing grain yield, economic benefit and farmers' income.
[0003] Soil preparation and fertilization are required before sowing wheat, hence the rotary tillers and seeders. In order to reduce the number of operations and improve economic benefits, agricultural machinery experts have developed rotary seeders. This kind of machine can be used for rotary tillage, fertilization, and sowing, suitable for all kinds of soil. It can complete various processes such as loosening soil, stubble cleaning, bedding, fertilizing and seeding in one operation. It will greatly reduce the input of manpower and material resources, and reduce the damage to soil layer, which is conducive to the sustainable development of agricultural production. For example, 2BFY-3 rotary seeder developed by Shijiazhuang Agricultural Machinery Plant and 2BQM seeder designed by Hu Honglie of China Agricultural University.
[0004] The most representative model is the 2 BMG -18 precision seeder designed by the Chinese Academy of Agricultural Mechanization Sciences and manufactured by its subsidiary, which can be used for conservation tillage and sowing. The sowing monomer adopts hinge-type profiling mechanism; the furrow opener is single-disc; the seeding apparatus is gear-type and controlled, which can realize precise and small-amount seed metering. By tractor traction, it makes the disc of the furrow opener rotate forward to achieve stubble cleaning or opening; wheels are mounted on both sides of the frame to support the frame and limit the depth.
[0005] But this seeder is not suitable for the land with large amount of straw returning to the field due to the use of the gear-type and controlled seeding apparatus for precise and small-amount seed metering, and does not meet the requirements of wide-row sowing mode for increasing yield. After returning corn straw to the field, preparing the soil and eliminating stubble, the amount of straw in the field is large, and the seeder is often jammed and entangled ueseriptions when working. To address this issue, YAAO no-tillage drill is equipped with knives on both sides of the furrow plough to remove straw and weeds from the seed bed. 2BMJF no-tillage precision seeder, jointly designed and developed by Zhejiang Liulin Technology Co., Ltd. and Northeast Agricultural University and produced by Heilongjiang Bunong Technology Co., LTD, is equipped with high-speed rotary cleaning device and fixed-shaft gear-type no-tillage cleaning and straw mulching device, which can realize cleaning before sowing, sowing belt cleaning and straw mulching after sowing. The no-tillage fertilizer seeder for wheat developed by Shandong Dahua Machinery Co., LTD is equipped with an anti-blocking device between the cutter shaft and disc. The 2BMQF-6 / 12A models of Luoyang Xinle Machinery Equipment Co., LTD adopt a kind of furrow opener with a cutter blade. The 2BMFS-6 / 12 shallow rotary tillage and seeding machine for wheat developed by Hebei Province Agricultural Mechanization Administration and Hebei Nonghaha Machinery Co., Ltd., is equipped with a special rotary tillage tool in front of the furrow opener, and fertilizer is applied to the side of the disc furrow opener at a depth of 5-6cm.
[0006] Though these models can solve the problems of congestion and entanglement, additional anti-blocking devices lead to complex mechanism, backward center and low utilization rate of
standardized parts and components of the implement.
[0007] Therefore, it is necessary to invent a kind of anti-congestion and anti-entanglement all-in-one machine integrating rotary tillage, fertilization, and seeding with moderate price and good performance indexes, featuring compact structure, simple parts, forward center of gravity,
good longitudinal stability of the unit, and high utilization rate of standardized parts and components.
Summary of the Invention
[0008] The main object of the present invention is to provide a new type of anti-congestion, anti-entanglement, rotary, wide-row, combined seed and fertilizer drill for deep fertilization of
wheat, in order to solve the technical problems of complex mechanism, backward center of gravity, longitudinal instability of the unit and low utilization rate of standardized parts of the implement, due to the additional anti-blocking device of the existing seeders.
[0009] In order to achieve the above objective, the present invention discloses a new type of anti-congestion, anti-entanglement, rotary, wide-row, combined seed and fertilizer drill for deep fertilization of wheat.

inner wall of the seed outlet of the spreader to disperse the seed. The preferred width for seed dispersal is 122 mm. The wide-range spreader is welded to the seed discharge tube at right angles. The spreader is mostly located outside the rotary blade roll.
[0044] In the preferred embodiment of the application of the present invention, the rib plate b is an included angle structure that puts the fertilizer discharge tube of the fertilizer discharge assembly and the seed discharge tube of the seed discharge assembly at an angle of 0, which is
70.
[0045] In the preferred embodiment of the present invention, the invention comprises a earth-covered non-metallic dragging plate which acts as a shell cover for retaining soil, crushing soil and leveling a sowed field, which is made of non-metallic material with good adaptability. Preferably, the earth-covered non-metal dragging plate is 2000mm in length and 250mm in
width. It includes a roller-shaped pressing wheel, in the shape of a cylinder. The preferred diameter of the roller-shaped pressing wheel is 326 mm. The function is to consolidate the soil layer containing a large number of crushed straw after sowing, on the one hand, to give the seeds
an appropriate seedbed, so that the seeds germinate, break through the soil and take root, on the other hand, to accelerate the maturation of straw in the soil layer.
[0046] In the preferred embodiment of the present invention, it includes a backing plate set in the same size and shape as the mounting plate but with different thickness to adjust the depth of
fertilization.
[0047] In the preferred embodiment of the present invention, as shown in FIG. 1, it comprises a frame, a three-point hitch, a rotary blade roll 7, a fertilizer box 1 and nine fertilizer apparatuses, a
seed box 20 and nine seeding apparatuses 17, a chain drive mechanism for driving the shaft of the fertilizer apparatuses and the shaft of the seeding apparatuses, eight furrow openers 8, an ueseriptions earth-covered non-metallic dragging plate 11, a roller-shaped pressing wheel 12 and other components. It is characterized in the fact that the frame is composed of a front beam of the frame 5, a rear beam of the frame 10, a rotary blade shaft side plate 6 and a frame side plate 15. The upper suspension frame 2 and the lower suspension frame 4 of the three-point suspension mechanism connected to the tractor are connected to the front beam 5 of the frame. The rotary blade roll 7 is mounted on the rotary blade shaft side plate 6 below the frame. The eight furrow openers 8 are row-wide mounted on the rear beam 10 of the frame, below the frame. They are in the set of the rotary blades of the rotary blade roll 7, within the range of soil casting backward by the rotary blade. Additional furrowing form is used under the middle reducer. The fertilizer box
1 and the seed box 20 are arranged above the frame, nine seeding apparatuses 17 are uniformly mounted on the bottom of the seed box 20, and nine fertilizer apparatuses 19 are uniformly mounted on the bottom of the fertilizer box 1. The fertilizer outlets and seed outlets of the eight
furrow openers 8 are connected to the fertilizer apparatus 19 and the seeding apparatus 17 by seed and fertilizer guiding corrugated pipes. The earth-covered non-metallic dragging plate 11 and the roller-shaped pressing wheel 12 are connected to the frame, which are successively behind the furrow openers 8. The roller-shaped pressing wheel 12 rolls through chain drives 18,
16 arranged at the sides of the implement to drive the fertilizer discharge shaft 18 and the seed discharge shaft 20 to work.
[0048] The seeder according to the present invention adopts a configuration of furrow openers and rotary blade rolls. The utility model is characterized in the fact that a furrow opener is
mounted on the rear beam of the seeder frame along the width direction (blade shaft axis) of the implement according to the seeding row spacing and every other row spacing. One end is fixedly connected to the rear beam of the frame, and the other end extends into the unblocked
circumferential space reserved for changing the direction of the rotary bent blade head, until below the rotary blade shaft, within the range of soil casting backward by the rotary blade. The new arrangement between the furrow openers and the rotary blade rolls enables the wide-width seeder to sow on the field with a large amount of straw returning to the field without congestion
and entanglement.
[0049] For the rotary blade roll in the application of the present invention, the rotary blades are arranged on the blade shaft in a double-headed one-way spiral. Most of the bent blades are
arranged alternately and symmetrically, that is, along the direction of the blade shaft, two rotary bent blades are mounted on the same circumference at regular intervals (that is, blade spacing), ueseriptions one to the left and the other to the right. However, in the direction along the blade shaft, every other sowing row spacing, the bending direction of the head of one of the two blades on the two adjacent circles is changed so as to leave a smooth circumferential space to accommodate a furrow opener. Other blades are mounted in the same direction. The seeder of the invention seeds nine rows, and the rotary blade roll has a total of 60 bent blades. It is necessary to change the bending direction of the heads of 16 bent blades on one side of each of the eight furrow openers.
[0050] As shown in FIG. 2, in the preferred embodiment of the present invention, the furrow opener comprises a fertilizer discharge assembly and a seed discharge assembly. The fertilizer discharge assembly is formed by welding a mounting plate 21, a rib plate a 22, a fertilizer
discharge tube 23, a fertilizer outlet 26, a furrowing blade 24, a rib plate b 25 and a seed tube holder 32. It is characterized in the fact that the mounting plate 21 is connected with a U-shaped retaining bolt of the seeder; the fertilizer discharge tube 23 is obliquely welded to the mounting
plate 21, and the rib plate 22 is welded between the two for reinforcing the ribs. The rib plate b 28 is welded to the other side of the fertilizer discharge tube 23, and the seed tube holder 32 is welded to the rib plate b 28 for fixing the seed tube. The seed discharge assembly is formed by welding the spreader 21, the seed discharge sheet 30, the seed outlet 29, and the seed discharge
tube 33. It is characterized in the fact that the spreader 31 is welded at right angles to the seed discharge tube 33, and the V-shaped seed discharge sheet 30 is welded at the seed outlet 29. The seed discharge assembly and the fertilizer discharge assembly are connected by a seed tube holder 32, and the seed discharge part is located at the edge of the rib b8. Before seeding, the nut
of the seed tube holder 32 can be loosened and moved to adjust the seeding depth.
[0051] In the further preferred embodiment of the present invention, the mounting plate 21 is parallel to the plane of the front and rear beams of the frame, and the furrow openers are
mounted under the rear beam of the frame by means of U-shaped bolts. The centerline of the fertilizer discharge tube 23 is inclined with respect to the plane of the mounting plate 21, preferably at an angle of 560, to ensure that the fertilizer discharge tube 23 does not interfere with the rotation of the rotary blade roll. Further, rib a 22 is welded at the angle between the
mounting plate 21 and the fertilizer discharge tube 23 to serve as a reinforcing rib.
[0052] Further, the fertilizer discharge tube 23 also serves as the handle of the furrowing blade 24, which should have sufficient strength and a certain large inner diameter, preferably a hollow
pipe having an outer diameter of 45 mm, an inner diameter of 36 mm and a wall thickness of 4.5 mm. The fertilizer outlet 26 is at the back of the bottom under the blade edge, 36 mm wide. The ueseriptions furrowing blade 24 is used to make a fertilizer trench, preferably with an entry angle a = 51 0, an entry gap angle , = 10 °, and a width B = 20 mm.
[0053] The rib plate b 28 is welded to the other side of the fertilizer discharge tube 23, and a seed tube holder 32 is welded thereon for fixing the seed pipe assembly, so that there is an angle between the fertilizer discharge tube 23 and the seed discharge tube 33. One of the functions of
this angle on the rib b 28 is to increase the distance between the fertilizer outlet and seed outlet in the horizontal and vertical direction. The horizontal distance is such that after the fertilizer falls into the trench, there is sufficient backfill time to fill the soil with sufficient thickness to allow the seed to fall on the first backfill. The distance in the vertical direction is to ensure the soil
layer thickness required by the agronomy between the fertilizer and the seed, so as to realize the positive depth fertilization of seed and fertilizer. After the depth of fertilization is determined, the horizontal and vertical distance between the fertilizer outlet and the seed outlet can be
adjusted by moving the seed discharge tube along the edge of the rib plate b 28. Preferably, When the fertilization depth is determined to be 103mm, and the vertical distance between the lowest point of seed outlet and the lowest point of fertilizer outlet is 53mm, the horizontal distance is 136mm, and the backfilling time is 136/600 = 0.23 s (the advance speed of the unit is
0.6m /s in general), the sowing depth is 50mm, and the thickness of soil layer between seed and fertilizer is 53mm.
[0054] Before sowing with the furrow opener, a backing plate is set in the same size and shape as the mounting plate 1 but with different thickness to adjust the depth of fertilization. Preferably,
the depth of fertilization adjusted by the furrow opener is 103 mm without a backing plate, ranging from 103 to 120 mm. Further, before sowing, after the depth of fertilization is determined, the seeding part can be moved along the edge of rib plate b8. The relative position of
seed outlet and fertilizer outlet, the seeding depth, and the thickness of soil layer between seed and fertilizer can be adjusted. Preferably, when the relative position between the seed outlet and the fertilizer outlet is adjusted and the depth of fertilization without a backing plate is 103mm, the vertical distance between the seed outlet and the fertilizer outlet is 53 mm, and the seeding
depth is 50, and the thickness of the soil layer between the seed outlet and the fertilizer is 53 mm. When the depth of fertilization with a backing plate is 120mm, the distance between the fertilizer outlet and the seed outlet is 70mm, the seeding depth is 50mm, and the thickness of the soil layer
between the seed and fertilizer is 70mm.

The wide spreader 31 is welded to the seed discharge tube 33 at right angles. The spreader 31 is mostly located outside the rotary blade roll.
[0056] The earth-covered non-metallic dragging plate used in the preferred embodiment of the present application serves as a shell cover for retaining soil, crushing soil, returning soil and leveling the sown field. It is made of non-metal material and has good adaptability. The preferred non-metallic dragging plate is 2000 mm long and 250 mm wide.
[0057] The roller of the roller-shaped pressing wheel used in the preferred embodiment of the present application is in the shape of a cylinder. The preferred diameter of the roller-shaped pressing wheel is 326 mm. The function is to consolidate the soil layer containing a large number of crushed straw after sowing, on the one hand, to give the seeds an appropriate seedbed, so that the seeds germinate, break through the soil and take root, on the other hand, to accelerate the maturation of straw in the soil layer.
[0058] Working principle: when working, the implement is connected with the tractor through the three-point suspension mechanism, and the tractor drives the implement forward. The power output shaft transmits part of the power of the tractor to the intermediate transmission reduction box 3, and the output shaft of the reduction box 3 drives the rotary blade roll to rotate for soil cutting operation. The pressing wheel rolls and drives the fertilizer apparatus and the seeding apparatus to work through a chain drive. The fertilizer apparatus guides the fertilizer through the fertilizer discharge tube into the fertilizer ditch opened by the furrow opener in the rotary blades, and the fertilizer is covered with rotary backfill. Then the seed is introduced into the spreader through the seed discharge tube, and the seed is spread on the first backfill, covered with soil, leveled with the non-metal dragging plate, and compacted with the roller-shaped pressing wheel. The whole process of rotary tillage, soil preparation, fertilizing, seeding, covering and pressing can be completed by one machine at a time
[0059] In the embodiments of the invention, by improving the structure of rotary blade roll and changing the direction of individual rotary bent blade head on rotary blade roll, a smooth circumferential space is formed. A furrow opener is set in the space, and there is no need to set up a separate anti-blocking device, so as to meet the requirements of anti-blocking operation, and simplify the overall structure. Therefore, the above problems of the prior art may be solved.
