Abstract

This utility model relates to a rotary tillage, fertilization, furrowing, and wide-width seeder for wet fields, including a rotary tillage fertilizer and a furrowing wide-width seeder. The rotary tillage fertilizer is fixedly equipped with a transmission mechanism for transmission connection with the output shaft of a tractor. The transmission mechanism is connected to the input shaft of the furrowing seeder. The rotary tillage fertilizer includes a rotary tiller frame, a rotary tiller left side plate, a rotary tiller right side plate, and a rotary tiller support. The rotary tiller support is fixedly equipped with a transmission mechanism that smooths the wheel tracks through left-hand and right-hand rotary tillers on the front and rear rotary tiller shafts. The furrowing roller is designed to cooperate with the inner and outer ring shovels. When wet soil clods stuck on the furrowing roller rotate to the corresponding inner and outer ring shovels, they are scraped off by the inner and outer ring shovels, thus ensuring normal furrowing and relatively consistent furrow depth. The left rotary tiller turns the soil on both sides of the furrow, thus completing the covering operation and avoiding the problem of soil sticking to the covering roller during pressing.

Description

Technical Field

[0001] This utility model relates to equipment for tillage operations in wet and rotten fields, specifically to a rotary tillage, fertilization, furrowing, and wide-width seeder for wet and rotten fields. Background Technology

[0002] In conditions of sludge-dampness (or wet-water conditions), which mainly refer to rice-wheat stubble fields with high moisture content or small amounts of water accumulation (water depth ≤ 2cm), the currently used dual-shaft rotary tillage, fertilization, and seeding machines mainly have the following problems: (1) High seed exposure rate: The sowing adopts the free broadcasting method (the seeds fall onto the surface of the soil after cultivation through the seed broadcasting board), and the seeds are covered by the shallow rotary blade shaft at the rear (the seeds are mixed and stirred in the soil), resulting in a high seed exposure rate; (2) Sowing depth cannot be controlled: Because the seeds are scattered on the surface after the front blade is rotary tilled, the seed covering depth is only achieved by rotating the shallow blades of the rear blade to mix the seeds in the soil. This seed covering method makes it impossible to control the consistency of sowing depth, resulting in a low germination rate.

[0003] Therefore, to change the above situation, row sowing can be used to effectively control the sowing depth and improve the emergence. Conventional row sowing machines, such as the compacted furrowing seeder disclosed in CN 118383109 A, can perform row sowing. This solution uses a ring-shaped furrowing blade to open the furrows. This solution is suitable for winter wheat areas in dry northern regions.

[0004] Due to the different land conditions in different regions, the compacted ditching and seeding machine disclosed in CN 118383109 A cannot solve the problem of wheel marks caused by the tractor during the tractor's movement when applied to wet and sparse land. In addition, during the ditching process, the annular ditching blades are easily covered with mud clods, making it impossible to ditch normally.

[0005] In addition, the patent uses a motor-driven pressing and covering roller for covering soil, which can keep the pressing and covering roller rotating continuously. However, the wet soil in the rotten wetland is very sticky, which quickly causes the pressing and covering roller to be covered with soil clumps, making it impossible to carry out normal covering work.

[0006] Therefore, our company has developed a rotary tillage, fertilization, furrowing, and wide-width seeder for wet and rotten fields, which integrates rotary tillage, stubble burying, furrowing, sowing, and soil covering into one machine that can be used in wet and rotten land. Summary of the Invention

[0007] This invention relates to a wide-width seeder for rotary tillage, fertilization, and furrowing in wet fields. It utilizes left-hand and right-hand rotary tillage blades on the front and rear rotary tillage shafts to smooth the wheel tracks. The furrowing roller is designed to work in conjunction with inner and outer shovels. When wet soil clods adhere to the furrowing roller, the roller continues to rotate due to the drive of the gearbox output shaft. As the wet soil clods rotate to the corresponding inner and outer shovels, they are scraped off, ensuring proper furrowing and consistent furrow depth. By installing left-hand and right-hand rotary tillage blades on the rotary tillage shaft, the left blade rotates the soil to the right on the left side of the furrow, while the right blade rotates the soil to the left on the right side, thus completing the soil covering operation after sowing. This eliminates the problem of soil sticking to the soil covering roller.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a rotary tillage, fertilization, furrowing, and wide-width seeder for wet and rotten fields, comprising a rotary tillage and fertilization machine and a furrowing and wide-width seeder. The rotary tillage and fertilization machine is fixedly equipped with a transmission mechanism for transmission connection with the output shaft of a tractor. The transmission mechanism is transmission-connected to the input shaft of the furrowing and wide-width seeder. The rotary tillage and fertilization machine includes a rotary tillage frame, which includes a left rotary tillage plate, a right rotary tillage plate, and a rotary tillage support located between the left and right rotary tillage plates and fixedly connected at both ends to the left and right rotary tillage plates, respectively. The transmission mechanism is fixedly installed on the rotary tillage support.

[0009] Based on the above scheme, as a preferred embodiment, the transmission mechanism includes a housing with a front cover, a rear cover, a left cover, and a right cover. A rotary tillage input shaft is rotatably mounted on the front cover via a bearing. The front end of the rotary tillage input shaft extends out of the front cover and is used to connect with the tractor output shaft. The rear end of the rotary tillage input shaft is located inside the housing and is fixedly mounted with a first bevel gear. The two ends of the front rotary tillage blade shaft and the rear rotary tillage blade shaft are rotatably connected to the left rotary tillage plate and the right rotary tillage plate, respectively. A first connecting shaft, which is driven by the first bevel gear, is rotatably connected to the left and right covers, and its two ends pass through the left and right covers and are fixedly connected to the second and third connecting shafts, respectively, via Y-type joints.

A dual-output shaft reducer is fixedly installed on the support frame. The front end of the dual-output shaft reducer has an input shaft, which is used for a third connecting shaft. The right side has a first output shaft, and the left side has a second output shaft. The right end of the furrow roller is driven to the first output shaft, which is driven to the furrow roller. The second output shaft is driven to the rotary tillage and covering mechanism installed on the frame. The rotary tillage and covering mechanism is located behind the furrow roller. A seed box is fixedly installed on the frame, and the seed discharge port of the seed box is located between the rotary tillage and covering mechanism and the furrow roller.

[0013] Based on the above scheme, as a preferred embodiment, the pressing roller includes a roller body and several pressing grooves that are evenly and spaced apart axially on the roller body. Specifically, the pressing grooves are annular, the roller body is cylindrical, and each pressing groove corresponds to a seed discharge port.

[0014] Based on the above scheme, as a preferred option, several outer ring shovel plates are fixedly installed on the outer ring shovel plate bracket. Each outer ring shovel plate corresponds to a pressing trench, and the width of the outer ring shovel plate is the same as the width of the pressing trench. The ends of the outer ring shovel plates are fitted with the pressing trench with a clearance. Several inner ring shovel plates are fixedly installed on the inner ring shovel plate bracket. Each inner ring shovel plate corresponds to a notch formed between the pressure groove and the roller body. The width of the inner ring shovel plate is slightly smaller than the width of the corresponding notch. The end of the inner ring shovel plate is fitted with the notch with a clearance.

[0015] Based on the above scheme, as a preferred embodiment, the first output shaft and the first drive shaft rotatably mounted on the right side plate are connected by an intermediate connecting shaft. The first output shaft and the intermediate connecting shaft, as well as the intermediate connecting shaft and the first drive shaft, are fixedly connected by Y-type joints. The first drive shaft is rotatably connected to the first drive shaft seat fixed on the right side plate. A first sprocket is fixedly mounted on the first extended section of the first drive shaft extending to the outside of the right side plate. A second drive shaft seat is fixedly mounted on the right side plate, and a second drive shaft is rotatably mounted on the second drive shaft seat via bearings. The second drive shaft is located on the second extension section outside the right side plate. A second main sprocket and a second auxiliary sprocket are fixedly installed on the extended section. The second main sprocket and the second auxiliary sprocket are spaced apart axially in the second extended section. The diameter of the second main sprocket is larger than that of the second auxiliary sprocket. The second main sprocket is connected to the first sprocket by a chain drive. The two ends of the grooving roller have a third drive shaft. The third drive shaft is rotatably connected to the third drive shaft seat fixed on the left side plate and the right side plate by bearings. The third drive shaft located at the right end of the grooving roller extends to the outside of the right side plate to form a third extended section. A third sprocket is fixedly installed on the third extended section. The third sprocket is connected to the second auxiliary sprocket by a chain drive.

[0016] Based on the above scheme, as a preferred embodiment, the seed box is connected to the seed outlet through a seed outlet pipe. The seed outlet pipe includes a vertical pipe, the upper end of which is connected to the seed outlet of the seed box through a flexible hose. The seed outlet is fixedly installed at the lower end of the vertical pipe, and the upper end of the vertical pipe is fixed to a horizontal bar. The seed outlet has a triangular cross-section in the left-right direction, including an inclined plate and a vertical plate. The lower edge of the inclined plate and the lower edge of the vertical plate are spaced apart, and the outlet of the seed outlet is flat.

[0017] Based on the above scheme, as a preferred embodiment, the rotary tillage and covering mechanism includes a rotary tillage and covering blade shaft. The two ends of the rotary tillage and covering blade shaft are rotatably connected to the rotary tillage and covering blade shaft seats fixed on the left and right sides of the plate through bearings. The rotary tillage and covering blade shaft is connected to the second output shaft through a gearbox installed on the left end face of the left side plate. The rotary tillage and covering blade shaft is provided with several sets of rotary tillage blades. Each set of rotary tillage blades corresponds to a furrow. Each set of rotary tillage blades includes a left rotary tillage blade and a right rotary tillage blade. The left rotary tillage blade is located on the left side of the corresponding furrow, and the right rotary tillage blade is located on the right side of the corresponding furrow. The left rotary tillage blade and the right rotary tillage blade are arranged in opposite directions.

[0018] Compared with the prior art, the beneficial effects of this utility model are: For wet and rotten fields, a rotary tiller and a wide-span seeder are used in series. After the rotary tiller fertilizes, tills, buryes the stubble, fills the pits, and scrapes the surface, the seeder immediately performs furrowing, sowing, covering the soil, and scraping the surface to achieve integrated operation.

[0019] Because tractor wheels can create deep craters when they travel, dual rotary tillage (front rotary tiller and rear rotary tiller) is used. After the front rotary tiller shaft fills the crater, the rear rotary tiller shaft fills it further, which reinforces the rotary tillage, stubble covering, and crater filling effects.

[0020] The rotary tillage input shaft, the first connecting shaft, and the fourth connecting shaft are connected by three bevel gears inside the transmission mechanism housing. By simply connecting the tractor's output shaft to the rotary tillage input shaft and the fourth connecting shaft to the input shaft of the dual output shaft reducer, the tractor's power can simultaneously drive the rotary tillage fertilizer applicator for rotary tillage, the furrowing and ditching of the wide-width seeder for furrowing and soil covering.

[0021] The furrowing roller of the furrowing seeder is driven by a dual-output shaft reducer. The furrowing roller rotates during the furrowing process. Compared with a non-powered furrowing roller, the furrowing roller will not have the problem of dragging, and the furrowing effect is better.

[0022] The design of the grooving roller in conjunction with the inner and outer ring scraper plates ensures that, when wet soil clods adhere to the grooving roller in wetland applications, the roller continues to rotate due to the output shaft drive of the dual output shaft reducer. When the wet soil clods adhering to the grooving roller rotate to the corresponding inner and outer ring scraper plates, they are scraped off by the inner and outer ring scraper plates, thus ensuring normal grooving and making the grooving depth relatively consistent.

[0023] The seed outlet is flat. Seeds fall from the vertical tube, land on the inclined plate, bounce off the vertical plate, fall back onto the inclined plate, bounce off the vertical plate again, and repeat this process multiple times before falling through the gaps into the furrows created by the pressing section. This method results in more uniform sowing compared to using a straight tube.

[0024] The left and right rotary tillers are set in opposite directions. The left rotary tiller rotates the soil to the right on the left side of the furrow created by the corresponding furrow, while the right rotary tiller rotates the soil to the left on the right side of the furrow created by the corresponding furrow, resulting in a better soil covering effect.

Specific implementation methods

[0026] The present invention will be further described below through embodiments, but the scope of the present invention is not limited thereto.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] like Figure 1-7 As shown, a rotary tillage, fertilization, furrowing, and wide-width seeder for wet and rotten fields includes a rotary tillage and fertilization machine and a furrowing and wide-width seeder. The rotary tillage and fertilization machine is fixedly equipped with a transmission mechanism for drive connection with the output shaft of a tractor. The transmission mechanism is drively connected to the input shaft of the furrowing and wide-width seeder.

[0029] The rotary tiller fertilizer applicator includes a rotary tiller frame, which includes a left rotary tiller plate 1, a right rotary tiller plate 2, and a rotary tiller support 3 located between the left and right rotary tiller plates and fixedly connected to the left and right rotary tiller plates at both ends, respectively. A transmission mechanism is fixedly installed on the rotary tiller support. The transmission mechanism includes a housing, which has a front cover 5, a rear cover 4, a left cover 6, and a right cover 7. A rotary tiller input shaft 8 is rotatably mounted on the front cover via bearings. The front end of the rotary tiller input shaft extends out of the front cover and is used to connect to the tractor output shaft, while the rear end of the rotary tiller input shaft is located inside the housing. A first bevel gear 9 is fixedly installed. The two ends of the front rotary tiller shaft 10 and the rear rotary tiller shaft 11 are rotatably connected to the left and right rotary tiller plates, respectively. A first connecting shaft 12 is rotatably connected to the left and right covers, and its two ends pass through the left and right covers and are fixedly connected to the second connecting shaft 13 and the third connecting shaft 14 via Y-type connectors. The second connecting shaft is rotatably connected to the right rotary tiller plate and passes through the right rotary tiller plate to drive the front rotary tiller shaft (the drive connection can be achieved through a gearbox, which is existing technology; a gearbox is typically formed by the sequential meshing of several gears, such as...). Figure 7As shown, a central shaft 61 is fixed to both the first gear 59 and the last gear 60. Two or three intermediate gears 63 can be installed between the first and last gears to form a gearbox consisting of several gears. These gears mesh sequentially in the vertical direction for transmission. The central shaft extends out of the gearbox housing 62. In this design, the second connecting shaft is fixedly connected to the central shaft of the first gear of the gearbox, and the front rotary tiller shaft is fixedly connected to the central shaft of the last gear (there are two intermediate gears). The third connecting shaft is rotatably connected to the left side plate of the rotary tiller and passes through the left side plate to drive the rear rotary tiller shaft. Several front rotary tillers 15 are fixedly installed on the front rotary tiller shaft, and several rear rotary tillers 16 are fixedly installed on the rear rotary tiller shaft. The front rotary tillers... The arrangement of the front rotary tillers on the shaft is the same as that of the rear rotary tillers on the shaft. The front and rear rotary tillers have the same shape but different sizes, with the front rotary tillers being larger than the rear rotary tillers. Both serve the same purpose: rotary tilling, burying stubble, and filling furrows. In wet, rotten fields where wheel tracks are deep, the rear rotary tillers provide reinforcement, especially in furrow filling. A second bevel gear 17 is fixedly installed on the first connecting shaft inside the housing, meshing with the first bevel gear. A fourth connecting shaft 18 is rotatably mounted on the rear end cover, and a third bevel gear 25 is fixedly installed on one end of the fourth connecting shaft inside the housing, meshing with the second bevel gear. The end of the third connecting shaft outside the housing is used to connect to the input shaft of the furrowing seeder.

[0030] Among them, the rotary tillers are aligned with the tractor tires in the front-to-back direction. Taking the axis of the tire in the front-to-back direction as a reference (the center line of the tire on one side in the front-to-back direction), the right-hand rotary tiller 58 on the left side turns the soil to the right, and the left-hand rotary tiller 57 on the right side turns the soil to the left, so as to smooth the grooves (tire prints) pressed by the tires.

[0031] The fertilizer box 27 is fixedly installed on the rotary tiller frame, and the scraper 56 is installed at the rear end. This part of the structure is the same as the traditional structure, and will not be described in detail here.

[0032] The front rotary tiller shaft breaks up the soil, burys the stubble, and initially levels the surface. The rear rotary tiller shaft performs shallow tillage, breaks up the soil, burys the stubble, and levels the surface. The scraper flattens the seedbed.

[0033] The wide-width furrow seeder includes a frame, which includes a left side plate 19, a right side plate 20, and a support frame 21 with one end fixedly connected to the left side plate and the other end fixedly connected to the right side plate. The left end of the furrow roller is rotatably connected to the left side plate, and the right end is rotatably connected to the right side plate. A dual-output shaft reducer 22 is fixedly installed on the support frame. The front end of the dual-output shaft reducer has an input shaft, which is used for a third connecting shaft. The right side has a first output shaft 23, and the left side has a second output shaft 24. The right end of the furrow roller is driven to the first output shaft, which is driven to the furrow roller. The second output shaft is driven to the rotary tillage and soil covering mechanism installed on the frame. The rotary tillage and soil covering mechanism is located behind the furrow roller. A seed box 26 is fixedly installed on the frame, and the seed discharge port 28 of the seed box is located between the rotary tillage and soil covering mechanism and the furrow roller.

[0034] The furrowing roller includes a roller body 29 and several furrow sections 30 that are evenly and spaced apart axially on the roller body to ensure consistent row spacing during sowing. The furrow sections can be an integral part of the roller body or separate parts welded together. Specifically, the furrow sections are annular, and the roller body is cylindrical.

[0035] Each furrow corresponds to a seed discharge point.

[0036] The width of the pressing furrow is usually 8-12cm, typically 10cm, but can be adjusted according to specific sowing requirements. The outer diameter (radius) of the roller is 4-5cm smaller than the outer diameter (radius) of the pressing furrow to ensure a furrow depth of 2-4cm.

[0037] Since this solution is primarily designed for use on wet and sludge-prone areas, it can also be applied to sandy areas. During the ditching process, soil tends to stick to the ditching section and the roller, making it difficult for the soil to detach automatically. Therefore, to prevent wet and sludge-prone soil from sticking to the ditching section and the roller, an outer ring soil-shoveling plate support 31 (square steel) and an inner ring soil-shoveling plate support (square steel) are designed. Several outer ring soil-shoveling plates 32 are fixedly installed on the outer ring soil-shoveling plate support. Each outer ring soil-shoveling plate corresponds to one ditching section, and the width of the outer ring soil-shoveling plate is the same as the width of the ditching section. The ends of the outer ring soil-shoveling plates are fitted with a gap to remove as much soil as possible from the ditching section without interfering with the rotation of the ditching roller. One end of the outer ring soil-shoveling plate support is fixed to the left side plate, and the other end is fixed to the right side plate, with its length direction parallel to the axial direction of the ditching roller.

[0038] Correspondingly, several inner ring shovel plates 34 are fixedly installed on the inner ring shovel plate bracket 33. Each inner ring shovel plate corresponds to a notch 35 formed between the pressing groove and the roller body. The width of the inner ring shovel plate is slightly smaller than the width of the corresponding notch. The end of the inner ring shovel plate is fitted with the notch with a clearance, and the side is fitted with the two sides of the notch with intervals. This removes as much soil stuck to the notch as possible without interfering with the rotation of the pressing roller. One end of the inner ring shovel plate bracket is fixed to the left side plate, and the other end is fixed to the right side plate. Its length direction is parallel to the axial direction of the pressing roller.

[0039] The first output shaft and the first drive shaft 36, which is rotatably mounted on the right side plate, are connected by an intermediate connecting shaft 37. The first output shaft and the intermediate connecting shaft, as well as the intermediate connecting shaft and the first drive shaft, are fixedly connected by Y-type joints. The first drive shaft and the first drive shaft seat 38, which is fixed on the right side plate, are connected by bearings to achieve the rotational relationship between the first drive shaft and the right side plate.

[0040] The first drive shaft extends out to the first protruding section 39 on the outside of the right side plate and the first sprocket 40 is fixedly installed.

[0041] A second drive shaft seat 41 is fixedly installed on the right side plate. A second drive shaft 42 is rotatably mounted on the second drive shaft seat via bearings. A second main sprocket 43 and a second auxiliary sprocket 44 are fixedly installed on the second extended section of the second drive shaft located on the outer side of the right side plate. The second main sprocket and the second auxiliary sprocket are spaced apart axially in the second extended section. The diameter of the second main sprocket is larger than the diameter of the second auxiliary sprocket. The second main sprocket is connected to the first sprocket via chain drive.

[0042] The grooving roller has a third drive shaft 45 at both ends. The third drive shaft is rotatably connected to the third drive shaft seat 46 fixed on the left and right side plates through bearings. The third drive shaft located at the right end of the grooving roller extends to the outside of the right side plate to form a third extension section 47. A third sprocket 48 is fixedly installed on the third extension section. The third sprocket is connected to the second auxiliary sprocket through chain drive.

[0043] The seed box is connected to the seed outlet via a seed dispensing pipe. Taking the location of the dual-output shaft reducer as a reference, the seed dispensing pipe includes a vertical pipe 49. The upper end of the vertical pipe is connected to the seed outlet of the seed box via a flexible hose. The seed outlet is fixedly installed at the lower end of the vertical pipe. The upper end of the vertical pipe is fixed to a horizontal bar (square steel, with both ends fixedly connected to the left and right side plates respectively). The length direction of the horizontal bar is left and right. The cross-section of the seed outlet in the left and right direction is triangular, including an inclined plate 50 and a vertical plate 51. The lower edge of the inclined plate and the lower edge of the vertical plate are spaced apart. The outlet of the seed outlet is flat. Seeds fall from the vertical pipe, land on the inclined plate, bounce and hit the vertical plate, fall back onto the inclined plate, bounce and hit again, and repeat this process multiple times before falling from the gap into the groove pressed out by the pressing part. This method results in more uniform sowing compared to a straight pipe.

[0044] The rotary tillage and covering mechanism includes a rotary tillage and covering blade shaft 52. Both ends of the shaft are rotatably connected to rotary tillage and covering blade shaft seats 53 fixed on the left and right side plates via bearings. The shaft is connected to a second output shaft via a gearbox mounted on the left end face of the left side plate. The shaft has several sets of rotary tillage blades, each set corresponding to a furrow. Each set includes a left rotary tillage blade 54 and a right rotary tillage blade 55. The left rotary tillage blade is located on the left side of the corresponding furrow, and the right rotary tillage blade is located on the right side. The left and right rotary tillage blades rotate in opposite directions; that is, the left rotary tillage blade rotates the soil to the right on the left side of the furrow created by the corresponding furrow, and the right rotary tillage blade rotates the soil to the left on the right side of the furrow created by the corresponding furrow, thus completing the covering operation of the furrow after sowing. A scraper is also installed at the rear end of the frame.

[0045] This product is mainly used in rice stubble wheat fields with high moisture content, when there is a small amount of standing water in the field (water depth ≤2cm) or when the tires of wheeled tractors are sunken by ≥20cm. It can still be used for timely and normal sowing operations, and the operation quality and seed germination rate are no less than those in dry fields.
