Description

Technical Field

[0001] This invention relates to the field of Astragalus membranaceus cultivation technology, and in particular to an integrated ridge-mulching and hole-sowing combined operation device. Background Technology

[0002] Astragalus is a commonly used Chinese medicinal herb, and its cultivation process has relatively strict agronomic requirements, especially the seedling stage, which usually requires multiple steps such as rotary tillage, ridging, mulching, sowing, and laying water and fertilizer pipelines.

[0003] Currently, the aforementioned operations in Astragalus membranaceus cultivation mainly rely on single-function agricultural machinery to complete them in stages. For example, a rotary tiller is first used for soil tillage, followed by a separate ridging machine for ridging, then a mulching machine for covering with plastic film, and finally, a seeder or manual sowing is performed. This step-by-step operation mode has the following technical problems: Dispersed functions and low operating efficiency: Multiple single machines need to enter the field multiple times, which not only consumes a lot of time and manpower, but also the repeated rolling of the soil by the machinery can easily cause soil compaction and destroy the formed ridges, resulting in high overall operating costs.

[0004] Poor agronomic compatibility: Existing general-purpose equipment is unable to meet the special agronomic requirements of Astragalus membranaceus, namely "deep furrow and high ridge, sowing under film, and precise seedling raising." In particular, key parameters such as ridge height, sowing accuracy, and sowing depth consistency are difficult to control precisely with ordinary equipment, affecting the uniformity and germination rate of Astragalus membranaceus seedlings.

[0005] Insufficient coordination: There is a lack of effective connection between various operation links, such as the order of mulching and sowing, and the alignment of drip irrigation pipes and seed holes. This can easily lead to problems such as misalignment of seed holes and film holes, and inaccurate water and fertilizer application, which will require manual assistance to break the film and release seedlings in the later stages, increasing labor intensity.

[0006] Lack of integrated design: Existing equipment does not effectively integrate functions such as rotary tillage, ridging, mulching, hole sowing and pipeline laying, resulting in cumbersome operation processes and difficulty in meeting the needs of standardized and large-scale seedling operations.

[0007] To address this, an integrated ridging, mulching, and hole-planting combined operation device is proposed. Summary of the Invention

[0008] In view of this, the present invention provides an integrated ridging, mulching and hole-planting combined operation device to solve or alleviate one of the technical problems existing in the prior art, and at least provides a beneficial option.

[0009] The technical solution of this invention is implemented as follows: An integrated ridging, mulching, and hill-sowing combined operation device includes a support component. The support component is equipped with a rotary tiller, a pipeline laying component, a mulch film laying component, a film pressing component, a ridging forming component, and a hill-sowing component, which are installed sequentially from front to back. The front end of the support component is used to connect to an agricultural tractor so that when the agricultural tractor tows the integrated machine, the rotary tillage, pipeline laying, mulch film laying, film pressing, ridging, and hill-sowing operations are completed sequentially from front to back.

[0010] A further preferred embodiment: the support component includes a bracket and rollers; the rear bottom of the bracket is evenly provided with several rollers to assist the movement of the all-in-one machine.

[0011] A further preferred embodiment: the pipeline laying assembly includes a first fixed shaft, a reel, a drip irrigation pipe, and a guide pipe; the first fixed shaft is installed on the inner side wall of the support, the reel is uniformly rotatably connected to the outer side wall of the first fixed shaft, the drip irrigation pipe is wound around the outer side wall of the reel, the guide pipe is uniformly fixedly connected to the inner side wall of the support, and one end of the drip irrigation pipe passes through the bottom end of the guide pipe.

[0012] A further preferred embodiment: the mulch film laying assembly includes a second fixed shaft and a take-up roller; The inner wall of the bracket is equipped with a second fixed shaft, and a take-up roller is wound around the outer wall of the second fixed shaft. The outer wall of the take-up roller is wound with mulch film.

[0013] A further preferred embodiment: the pressing assembly includes a pressing wheel and a through groove; the pressing wheel is rotatably connected to the inner side wall of the bracket, the pressing wheel has an internal hollow structure, and the outer side wall of the pressing wheel has a through groove.

[0014] A further preferred embodiment: the ridge forming assembly includes a mounting sleeve, a connecting rod, and an extrusion wheel; the mounting sleeve is fixedly connected to the inner side wall of the bracket, the connecting rod is detachably connected to the inner side wall of the mounting sleeve, and one end of the connecting rod is rotatably connected to the extrusion wheel.

[0015] A further preferred embodiment: the seeding assembly includes a third fixed shaft, a connecting sleeve, a support, a seed box, and a duckbill-type seeder; The inner wall of the bracket is equipped with a third fixed shaft, the outer wall of the third fixed shaft is uniformly rotatably connected to a connecting sleeve, the outer wall of the connecting sleeve is fixedly connected to a support, the inner wall of the support is rotatably connected to a seed box, and the outer wall of the seed box is uniformly fixedly connected to a duckbill-type burrowing device.

[0016] A further preferred embodiment: the rotary tiller is installed at the bottom front end of the support frame and is used for pre-tilling and breaking up the soil.

[0017] A further preferred embodiment: the bottom end of the guide tube is close to the ground, used to guide the drip irrigation pipe to be laid on the surface of the soil after rotary tillage.

[0018] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: 1. This invention integrates the rotary tiller, pipeline laying assembly, mulch film laying assembly, film pressing assembly, ridge forming assembly, and hill seeding assembly into a single support assembly in an optimized sequence. This allows the equipment to complete rotary tillage, drip irrigation pipe laying, mulch film covering, film pressing, ridge forming, and hill seeding in a single operation. Compared to traditional multi-step operations, this reduces the number of times the machine needs to enter the field, lowers soil compaction, improves overall operational efficiency, and saves labor costs.

[0019] This invention employs a sequence of first laying drip irrigation pipes and mulch film, followed by ridging and hole sowing. Drip irrigation pipes and mulch film are pre-placed on the rotary-tilled soil surface using pipe-laying and mulch film-laying components. During ridging, the subsequent ridging component (extrusion wheel) compresses the soil from both sides towards the center, naturally covering the drip irrigation pipes and mulch film onto the formed ridge surface. This ensures precise alignment between the drip irrigation pipes and the planting holes, avoids misalignment of the mulch film holes, eliminates the need for subsequent manual film breaking, and meets the agronomic requirements for Astragalus membranaceus seedling cultivation.

[0020] The ridge-forming component of this invention adopts a detachable connection structure of mounting sleeve, connecting rod, and extrusion wheel, which can adjust the ridge height and ridge width according to agronomic needs. The seed box of the hill-sowing component is rotatably connected to the connecting sleeve through a support, which can flexibly adjust the soil entry angle and depth of the duckbill-type hill-sowing device, thereby achieving precise control of the sowing depth, which is beneficial to improving seed germination rate and seedling uniformity.

[0021] Through the guide tubes in the pipeline laying assembly, the drip irrigation pipes are precisely guided and laid on the surface of the soil after rotary tillage, and then covered by the soil during the ridging process. This method of laying drip irrigation under mulch facilitates precise integrated water and fertilizer management in the later stages, reduces water evaporation and fertilizer loss, and provides a good water and fertilizer environment for the germination of Astragalus seeds and the growth of seedlings.

[0022] This invention integrates multiple core processes required for Astragalus seedling cultivation, reducing the number of tractors and agricultural machinery required, shortening the operation cycle, and decreasing reliance on skilled operators. Simultaneously, improved operation quality ensures seedling emergence rate and seedling quality, thereby enhancing the overall economic benefits of Astragalus seedling cultivation.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-4 As shown, this embodiment of the invention provides an integrated ridging, mulching, and hill-sowing combined operation device, including a support component 1. The support component 1 is equipped with a rotary tiller 2, a pipeline laying component 3, a mulch film laying component 4, a film pressing component 5, a ridging forming component 6, and a hill-sowing component 7, which are installed sequentially from front to back. The front end of the support component 1 is used to connect to an agricultural tractor so that when the agricultural tractor tows the integrated machine, the rotary tillage, pipeline laying, mulch film laying, film pressing, ridging, and hill-sowing operations are completed sequentially from front to back.

[0030] Specifically, the support assembly 1 serves as the load-bearing skeleton of the entire machine, used to fix and connect various functional components. The support assembly 1 includes a bracket 11 and rollers 12. The bracket 11 is a frame structure welded from rectangular steel pipes, possessing sufficient strength and rigidity to withstand loads during operation. Several rollers 12 are evenly distributed at the rear bottom of the bracket 11. These rollers 12 contact the ground and move with the integrated machine during operation, providing auxiliary support and balancing the entire machine, preventing the rear end of the bracket 11 from sinking due to gravity and affecting the consistency of the working depth.

[0031] The pipeline laying assembly 3 is used to lay drip irrigation pipes on the surface of the soil after rotary tillage, preparing for subsequent drip irrigation under film. Specifically, the pipeline laying assembly 3 includes a first fixed shaft 31, a drum 32, a drip irrigation pipe 33, and a guide pipe 34. The first fixed shaft 31 is installed on the inner wall of the support 11, and the drum 32 is evenly rotatably connected to the outer wall of the first fixed shaft 31. The drum 32 can rotate freely around the first fixed shaft 31. The drip irrigation pipe 33 is wound around the outer wall of the drum 32. When the integrated machine moves forward, the drip irrigation pipe 33 is pulled out from the drum 32. The guide pipe 34 is evenly fixedly connected to the inner wall of the support 11. The guide pipe 34 is in the shape of a downwardly inclined curved pipe, and one end of the drip irrigation pipe 33 passes through the bottom end of the guide pipe 34. The bottom end of the guide pipe 34 is close to the ground, which can accurately guide the drip irrigation pipe 33 to be laid on the surface of the soil after rotary tillage, avoiding the drip irrigation pipe 33 from shifting or tangling.

[0032] The mulch film laying assembly 4 is used to cover the soil surface after the drip irrigation pipes are laid with mulch film to retain moisture, increase temperature, and suppress weeds. Specifically, the mulch film laying assembly 4 includes a second fixed shaft 41 and a take-up roller 42; the second fixed shaft 41 is installed on the inner wall of the support 11, and the take-up roller 42 is wound around the outer wall of the second fixed shaft 41, and the take-up roller 42 can rotate around the second fixed shaft 41. The mulch film is wound on the outer wall of the take-up roller 42. When the integrated machine moves forward, the mulch film is passively unfolded from the take-up roller 42 and flatly covers the soil surface where the drip irrigation pipes have been laid.

[0033] The film pressing assembly 5 is used to flatten the covered mulch film and prevent it from being blown away or displaced by the wind. Specifically, the film pressing assembly 5 includes a pressing wheel 51 and a channel 52; the pressing wheel 51 is rotatably connected to the inner wall of the support 11, and the pressing wheel 51 is located behind the mulch film laying assembly 4. The pressing wheel 51 has an internal hollow structure to allow soil to be inserted, and the outer wall of the pressing wheel 51 has a channel 52. The channel 52 is evenly distributed along the circumference of the pressing wheel 51 so that some soil is covered on the surface of the mulch film during movement, preventing the mulch film from being blown away or displaced by the wind.

[0034] The ridge-forming component 6 is used to compress loose soil after rotary tillage into trapezoidal ridges that meet agronomic requirements. Specifically, the ridge-forming component 6 includes an installation sleeve 61, a connecting rod 62, and a compression wheel 63. The installation sleeve 61 is fixedly connected to the inner wall of the support 11, and the connecting rod 62 is detachably connected to the inner wall of the installation sleeve 61. One end of the connecting rod 62 is rotatably connected to the compression wheel 63. The connecting rod 62 is inserted into the installation sleeve 61, and the relative height and angle of the compression wheel 63 can be changed by adjusting the insertion depth or by replacing the connecting rod 62 with one of different lengths, thereby adjusting the height and width of the formed ridge. The compression wheel 63 is conical or frustum-shaped. When the integrated machine moves forward, the compression wheel 63 compresses the loose soil covered by the mulch film, causing the soil to gather to both sides and upwards, forming a ridge with a trapezoidal cross-section, while simultaneously covering the mulch film and drip irrigation pipes inside or on the surface of the ridge.

[0035] The hill-sowing component 7 is used to punch holes in the formed ridges for sowing, precisely planting Astragalus seeds into the planting holes. Specifically, the hill-sowing component 7 includes a third fixed shaft 71, a connecting sleeve 72, a support 73, a seed box 74, and duckbill-type hole-forming devices 75. The third fixed shaft 71 is installed on the inner wall of the support 11, and the connecting sleeve 72 is rotatably connected to the outer wall of the third fixed shaft 71. The connecting sleeve 72 can rotate around the third fixed shaft 71. The support 73 is fixedly connected to the outer wall of the connecting sleeve 72, and the seed box 74 is rotatably connected to the inner wall of the support 73. The seed box 74 is used to store Astragalus seeds, and a seed metering mechanism can be set inside the seed box 74. Multiple duckbill-type hole-forming devices 75 are evenly fixedly connected to the outer wall of the seed box 74, and the duckbill-type hole-forming devices 75 rotate together with the seed box 74. As the machine moves forward, the duckbill-type seeder 75 inserts into the soil of the ridge to form a seed hole. At the same time, the seeds in the seed box 74 fall into the duckbill-type seeder 75 through the seed metering mechanism. Then the duckbill opens to release the seeds into the seed hole, completing the sowing.

[0036] The rotary tiller 2 is installed at the front bottom of the support frame 11, located at the very front of the machine. The rotary tiller 2 includes a rotary blade shaft and several rotary blades, and is driven to rotate by the tractor's power take-off shaft. The rotary tiller 2 is used to pre-till and break up the soil, breaking up and loosening the compacted soil to create good seedbed conditions for subsequent ridging and sowing.

[0037] The bottom end of the guide tube 34 is close to the ground and is used to guide the drip irrigation pipe 33 to be laid on the surface of the soil after rotary tillage. The guide tube 34 is made of metal or wear-resistant plastic, and the distance between its bottom end and the ground is controlled at 1-3 cm. This ensures that the drip irrigation pipe 33 can be pulled out and laid on the ground smoothly, while avoiding the increase of resistance or damage to the drip irrigation pipe 33 due to the guide tube 34 being inserted into the soil too deeply.

[0038] In operation, the present invention works as follows: First, the front end of the support assembly 1 is connected to an agricultural tractor via a three-point suspension device, and the tractor's power take-off shaft drives the rotary tiller 2 to rotate. The tractor is started and moves forward, and the rotary tiller 2 breaks up and loosens the soil. Then, the drip irrigation pipe 33 in the pipeline laying assembly 3 is laid on the surface of the tilled soil under the guidance of the guide pipe 34. Next, the mulch film laying assembly 4 covers the drip irrigation pipe 33 with mulch film. The pressing rollers 51 of the pressing assembly 5 press the sides of the mulch film into the soil to prevent displacement. Then, the extrusion rollers 63 of the ridge forming assembly 6 compress the soil covering the mulch film to form a trapezoidal ridge, firmly encasing the mulch film and drip irrigation pipe within the ridge. Finally, the duckbill-type hole-forming device 75 of the hole-seeding assembly 7 punches holes in the top of the ridge and sows seeds, completing the entire process. The entire operation process, including rotary tillage, drip irrigation pipe laying, mulching, film pressing, ridging, and hole sowing, is completed in one go, improving the efficiency and agronomic precision of Astragalus seedling cultivation.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
