Description

Technical Field

[0001] This invention relates to the field of drip irrigation tape laying technology, and more particularly to a mechanism for synchronous laying of drip irrigation tape. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] A new type of slope water-saving drip irrigation technology is emerging. It involves creating ridges in the field, planting grain crops on the slopes, and then drip irrigation at the top of the slopes. The drip irrigation moistens the slopes in a point source or line source manner, which can greatly reduce the amount of drip tape used per unit area, while ensuring that wheat that is traveling far receives sufficient irrigation.

[0004] Currently, in the aforementioned slope-based water-saving drip irrigation technology, the drip irrigation tape laying mechanism is typically installed behind the agricultural machinery. As the machinery moves, this mechanism digs trenches and lays the drip irrigation tape at the top of the slope. Initially, one end of the drip irrigation tape is manually fixed in the field (by foot). Then, the machinery moves forward, and the trenching component on the drip irrigation tape laying mechanism breaks the soil and digs trenches at the top of the slope. As the machinery moves, the drip irrigation tape, rolled up on the machinery, is automatically unwound under tension and guided through a pre-set guide groove into a pre-buried trench behind the trenching component. Finally, a soil-covering plate installed behind the trenching component covers the drip irrigation tape with soil.

[0005] However, the aforementioned drip irrigation tape laying mechanism requires manual fixation of one end of the drip irrigation tape for an extended period during the initial laying stage, until the tape is laid long enough and its own friction is sufficient to automatically unwind it. This affects the efficiency of manual work. Furthermore, the drip irrigation tape is always taut during the laying process, and the tape entering the pre-buried trench is prone to floating out of the trench under tension, resulting in the tape being exposed to the outside environment and accelerating its aging. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a mechanism for the synchronous laying of drip irrigation tape.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a drip irrigation tape synchronous laying mechanism, comprising: Fixing plate; The trenching component, located at the bottom of the fixing plate, is used to break the soil and create trenches for pre-burying drip irrigation tape. The unwinding component, located at the bottom of the fixed plate and behind the trenching component in the direction of travel, includes a first rotating shaft, a second rotating shaft, and a third rotating shaft rotatably mounted on the bottom of the fixed plate and arranged parallel to each other. At least one end of the first rotating shaft is provided with a rotating wheel, which is used to contact the ground during unwinding and drive the first rotating shaft to rotate during travel. A transmission component is provided between the first and second rotating shafts, which is used to make the first and second rotating shafts rotate synchronously and to make the linear velocity of the rotating wheel equal to the linear velocity of the outer surface of the second rotating shaft. The drip irrigation tape passes through the gap between the second and third rotating shafts from top to bottom and is held by the second and third rotating shafts. The rotation of the second rotating shaft applies a tensile force to the drip irrigation tape to achieve the laying of the drip irrigation tape.

[0008] Furthermore, the first rotating shaft, the second rotating shaft, and the third rotating shaft are arranged sequentially in the direction away from the groove component, and the transmission component includes a first gear disposed on the first rotating shaft and a second gear disposed on the second rotating shaft, the first gear and the second gear meshing with each other.

[0009] Furthermore, the rotating wheels are disposed at both ends of the first rotating shaft, and the outside of the rotating wheels is provided with insert teeth that contact the ground and can be inserted into the soil.

[0010] Furthermore, the bottom of the fixing plate is provided with two mounting plates, and the two ends of the first rotating shaft, the second rotating shaft and the third rotating shaft are respectively rotatably disposed between the two mounting plates. The rotating wheel is located on the side of the two mounting plates that are far apart from each other, and the end of the first rotating shaft passes through the mounting plate and is connected to the corresponding rotating wheel. The outer side of the third rotating shaft is fitted with a rotating cylinder. Both ends of the third rotating shaft extend out of the mounting plate and are also fitted with rotating wheels on the side of the mounting plate that is far apart from each other. Furthermore, a transmission assembly is provided between the rotating wheels on the same side of the first rotating shaft and the second rotating shaft to enable the two rotating wheels on the same side to rotate synchronously.

[0011] Furthermore, friction is increased by roughening the surfaces of the second rotating shaft and the rotating drum.

[0012] Furthermore, it also includes a soil covering component, which is located at the bottom of the fixing plate and on the side of the fixing plate away from the trench component. The soil covering component includes two soil covering plates distributed in a figure-eight shape, with the outwardly flared side of the figure-eight facing the unwinding component. The soil covering plate is provided with a plurality of first scraping teeth on the side of the soil corresponding to the soil. The soil covering plate scrapes out soil fragments at the top of the slope through the first scraping teeth and covers the drip irrigation tape with soil through the soil fragments during the movement.

[0013] Furthermore, the trenching component is a wedge-shaped block, with one end away from the unwinding component being triangular in shape to break the soil and form a pre-buried trench. The bottom of the wedge-shaped block is a flat surface, and a rotating cavity is also provided at the bottom of the wedge-shaped block. A raking ridge is rotatably arranged in the rotating cavity. The raking ridge has multiple raking teeth, which can extend out of the rotating cavity to the bottom of the wedge-shaped block and contact the bottom surface of the pre-buried trench. The raking ridge can rotate synchronously with the movement of the wedge-shaped block to loosen the soil at the bottom of the pre-buried trench.

[0014] Furthermore, a guide hole is provided inside the wedge-shaped block, with one end of the guide hole facing the fixing plate and the other end facing the unwinding component. A clearance hole is provided on the fixing plate at the position corresponding to the guide hole. One end of the drip irrigation tape passes through the clearance hole and the guide hole from top to bottom and enters the unwinding component.

[0015] Furthermore, it also includes a scraper plate disposed at the bottom of the fixed plate, the bottom of the scraper plate having a contour shape that matches the slope of the slope, and the scraper plate having a second scraping tooth at the corresponding slope of the slope for scraping the surface of the slope.

[0016] The beneficial effects of this invention are reflected in: This invention utilizes agricultural machinery to move a fixed plate. As the fixed plate moves, the ditching component breaks the soil and opens a ditch at the top of the slope. The rotating wheel, through contact with the top of the slope, drives the first and second rotating shafts to rotate synchronously. Since the linear velocity of the rotating wheel and the linear velocity of the outer surface of the second rotating shaft are equal, the second rotating shaft can lower the drip irrigation tape according to the distance the agricultural machinery has traveled, eliminating the need for manual assistance in fixing the drip irrigation tape during the initial stage of laying. Furthermore, the drip irrigation tape entering the pre-buried trench using this method is in a stress-free state and is less likely to float out of the trench, effectively preventing the drip irrigation tape from being exposed to the outside.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4 This invention discloses a drip irrigation tape synchronous laying mechanism, comprising: Fixing plate 1; The trenching component 2 is set at the bottom of the fixing plate 1 and is used to break the soil to open the trench for pre-burying the drip irrigation tape; The unwinding component 3 is disposed at the bottom of the fixed plate 1 and located behind the grooving component 2 in the direction of travel. It includes a first rotating shaft 31, a second rotating shaft 32, and a third rotating shaft 33, which are rotatably disposed at the bottom of the fixed plate 1 and arranged parallel to each other. At least one end of the first rotating shaft 31 is provided with a rotating wheel 34, which is used to contact the ground during unwinding and drive the first rotating shaft 31 to rotate during travel. A transmission component is disposed between the first rotating shaft 31 and the second rotating shaft 32, which is used to make the first rotating shaft 31 rotate. 1. The second rotating shaft 32 rotates synchronously, and the linear velocity of the rotating wheel 34 (i.e., the distance swept by a point on the outer surface of the rotating wheel 34 per unit time) is equal to the linear velocity of the outer surface of the second rotating shaft 32 (i.e., the distance swept by a point on the outer surface of the second rotating shaft 32 per unit time). The drip irrigation tape passes through the gap between the second rotating shaft 32 and the third rotating shaft 33 from top to bottom and is clamped by the second rotating shaft 32 and the third rotating shaft 33. The rotation of the second rotating shaft 32 applies a tensile force to the drip irrigation tape to achieve the laying of the drip irrigation tape.

[0021] In practice, the fixed plate 1 is moved by the agricultural machinery. When the fixed plate 1 moves, the ditching component 2 breaks the soil and opens the ditch at the top of the slope. The rotating wheel 34 drives the first rotating shaft 31 and the second rotating shaft 32 to rotate synchronously by contacting the top of the slope. Since the linear velocity of the rotating wheel 34 and the linear velocity of the outer surface of the second rotating shaft 32 are equal, the second rotating shaft 32 can lower the drip irrigation tape according to the distance the agricultural machinery has traveled. In this way, it is not necessary to manually fix one end of the drip irrigation tape in the initial stage of laying the drip irrigation tape. Moreover, the drip irrigation tape that enters the pre-buried trench using this method is in a state of no force and is not easy to float up from the pre-buried trench, which can effectively prevent the drip irrigation tape from being exposed to the outside.

[0022] Preferably, the system also includes a linkage assembly disposed on the fixed plate 1, which is used to connect the fixed plate 1 to the agricultural machinery. It should be noted that the linkage assembly can be any commonly used linkage assembly for connecting agricultural machinery in the prior art (the figure is for illustrative purposes only), therefore, the structure of the linkage assembly will not be described in detail here.

[0023] In one embodiment, the first rotating shaft 31, the second rotating shaft 32 and the third rotating shaft 33 are arranged sequentially in a direction away from the groove component 2. The transmission component includes a first gear 35 disposed on the first rotating shaft 31 and a second gear 36 disposed on the second rotating shaft 32. The first gear 35 and the second gear 36 mesh with each other.

[0024] In one embodiment, the rotating wheel 34 is disposed at both ends of the first rotating shaft 31, and the outer surface of the rotating wheel 34 is provided with insert teeth 341 that contact the ground and can be inserted into the soil. This design not only avoids the rotating wheel 34 from slipping, but also makes it suitable for uneven ground and avoids suspension.

[0025] In one embodiment, the bottom of the fixing plate 1 is provided with two mounting plates 11, and the two ends of the first rotating shaft 31, the second rotating shaft 32 and the third rotating shaft 33 are respectively rotatably disposed between the two mounting plates 11. The rotating wheel 34 is located on the side of the two mounting plates 11 that are far apart from each other, and the end of the first rotating shaft 31 passes through the mounting plate 11 and is connected to the corresponding rotating wheel 34. The outer side of the third rotating shaft 33 is fitted with a rotating cylinder 37. Both ends of the third rotating shaft 33 extend out of the mounting plate 11 and rotating wheels 34 are also installed on the side of the mounting plate 11 that is far apart from each other. Furthermore, a transmission assembly 38 is provided between the rotating wheels 34 on the same side of the first rotating shaft 31 and the second rotating shaft 32 to make the two rotating wheels 34 on the same side rotate synchronously.

[0026] In specific implementation, by also setting rotating wheels 34 at both ends of the third rotating shaft 33, the rotating wheels 34 on the first rotating shaft 31 can assist the first rotating shaft 31 in rotating when they are suspended and cannot rotate (such as when encountering a small pit), thereby improving the equipment's ability to overcome obstacles.

[0027] It should be added that the two rotating wheels 34 on the same side do not interfere with each other and rotate synchronously only through the transmission assembly 38.

[0028] Preferably, the transmission assembly 38 can be a chain drive assembly including two sprockets and a chain, or a belt drive assembly including two pulleys and a drive belt, with the two sprockets or two pulleys coaxially mounted with two rotating wheels 34 on the same side.

[0029] Preferably, by roughening the surfaces of the second rotating shaft 32 and the rotating drum 37, the friction is increased, preventing the second rotating shaft 32 and the rotating drum 37 from slipping relative to the drip irrigation tape. There are many ways to roughen the surfaces of the second rotating shaft 32 and the rotating drum 37. For example, a textured pattern can be rolled onto the outer surface, or a rubber sleeve with good friction performance can be fitted over the second rotating shaft 32 and the rotating drum 37. There are many methods, and no specific limitation is made here.

[0030] In one embodiment, a soil covering component 4 is also included. The soil covering component 4 is disposed at the bottom of the fixing plate 1 and located on the side of the fixing plate 1 away from the unwinding component 3. The soil covering component 4 includes two soil covering plates 41 arranged in a figure-eight shape. The outward side of the figure-eight shape faces the unwinding component 3. The soil covering plate 41 is provided with a plurality of first scraping teeth 42 on the side of the ground corresponding to the soil surface. The soil covering plate 41 scrapes out soil fragments at the top of the slope through the first scraping teeth 42 and covers the drip irrigation tape with soil through the soil fragments during the process of moving.

[0031] In practice, since the slope is formed by pressing with an inclined wheel, the surface of the slope becomes compacted. If a traditional soil covering board 41 structure is used for covering, there will easily be no soil left to cover (because there is no broken soil, it is compacted during the slope shaping process). If a regular vertical first scraper tooth 42 is set, even if soil can be covered, the compacted soil on the slope surface will produce large bumps, which will not only easily damage the slope shape but also cause large soil clods to get stuck at the bottom of the fixed plate 1, increasing the energy consumption of the agricultural machinery. It could even force agricultural machinery to stop or break the soil covering plate 41; however, the "eight"-shaped distribution of the soil covering plate 41 used in this application means that even if there are extra soil clods, they will be discharged from the gaps in the "eight" shape, which is not easy to damage the "eight" shape. Moreover, the soil is scraped from both sides at an angle, so the soil on one side is relatively less stressed and the overall disturbance is small. Since the "eight"-shaped distribution of the soil covering plate 41 is not easy to form large protrusions during the movement and is easier to gather the soil, the protrusions cover the drip irrigation tape in a fine manner, and the drip irrigation tape is more comprehensively covered and less likely to be exposed.

[0032] In one embodiment, the trenching component 2 is a wedge-shaped block, with one end away from the unwinding component 3 being triangular and used to break the soil to form a pre-buried trench. The bottom of the wedge-shaped block is a flat surface, and a rotating cavity 21 is also provided at the bottom of the wedge-shaped block. A ground ridge 22 is rotatably arranged in the rotating cavity 21. The ground ridge 22 has multiple ground teeth 23. The ground teeth 23 can extend out of the rotating cavity 21 to the bottom of the wedge-shaped block and contact the bottom surface of the pre-buried trench. The ground ridge 22 can rotate synchronously with the movement of the wedge-shaped block to loosen the soil at the bottom of the pre-buried trench.

[0033] In practice, the wedge-shaped section with a triangular face for breaking the soil has good flow conductivity, effectively reducing resistance during trenching and ensuring smooth operation. Simultaneously, setting the bottom of the wedge as a flat plane creates a wider and flat trench bottom, facilitating accurate drip irrigation tape installation. However, this method of squeezing and breaking the soil can cause soil compaction at the bottom of the trench, affecting water infiltration (severe compaction can lead to water accumulation in the trench, with a large amount eventually overflowing the top and flowing down the slope, resulting in incomplete irrigation and difficulty in retaining moisture). Therefore, the design of the rolling ridge 22 loosens the soil at the bottom of the trench, accelerating water infiltration and allowing water to quickly penetrate into the seed rows for irrigation.

[0034] Preferably, the rolling ridge 22 is cylindrical in shape, and the rolling teeth 23 are distributed on the circumferential surface of the cylindrical shape; of course, the rolling teeth 23 can have various forms, such as being distributed on the circumferential surface of the cylindrical shape in the form of a cylinder; the rolling teeth 23 can also be in the shape of a toothed disc, with a cylindrical outer surface coaxially arranged.

[0035] Preferably, the wedge-shaped block has a guide hole 24 inside, with one end of the guide hole 24 facing the fixing plate 1 and the other end facing the unwinding component 3. The fixing plate 1 has a clearance hole 12 at the corresponding position of the guide hole 24. One end of the drip irrigation tape passes through the clearance hole 12 and the guide hole 24 from top to bottom and enters the unwinding component 3. Of course, the drip irrigation tape can also be directly inserted into the opening on the fixing plate 1, so that one end of the drip irrigation tape enters the unwinding component 3.

[0036] In one embodiment, a scraper 5 is also provided at the bottom of the fixed plate 1. The bottom of the scraper 5 has a contour shape that matches the slope of the slope. The scraper 5 is provided with a second scraper tooth 51 at the slope of the slope. The second scraper tooth 51 is located on the rear side of the soil covering component 4 and is used to scrape the surface of the slope.

[0037] In practice, since the existing technology uses compression to form the slope, the surface of the slope is nearly smooth and has a serious problem of compaction. When water falls on the surface of the slope, it easily gathers into streams and forms runoff. By scraping the surface of the slope, the compaction of the slope surface is broken up, preventing runoff from forming on the surface of the slope and accelerating the infiltration of water on the slope surface into the interior of the slope. At the same time, the soil scraper 5 located in the seed row breaks up the compacted soil above the seeds, which is conducive to the seeds breaking through the soil and improving the germination rate.

[0038] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0039] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0040] Additionally, "multiple" refers to two or more.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
