Description

Technical Field

[0001] This utility model relates to the field of agricultural sowing technology, and in particular to an agricultural planting device with sowing and water supply functions. Background Technology

[0002] With the continuous progress of society, traditional agricultural cultivation techniques are also developing and updating rapidly. Nowadays, large-scale agricultural planting techniques have basically achieved automation. For example, the emergence of rotary tillers, disc plows and seeders for tilling the land has greatly reduced the manpower burden of agricultural planting and improved planting efficiency.

[0003] Although current agricultural techniques are quite advanced, the integration of automatic seeding and irrigation is not yet widespread. The basic approach still involves planting followed by manual or mechanical watering, which requires considerable manpower and time. Therefore, we propose an agricultural planting device with integrated seeding and irrigation functions. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes an agricultural planting device with sowing and water supply functions, which can more accurately solve the problems mentioned above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes an agricultural planting device with sowing and water supply functions, including a water distribution valve and an automatic water supply device. The water distribution valve is fixed on the suspension, with one end connected to the outlet of an intelligent water pump via a water pipe, and the other end having two outlets connected to the irrigation and spraying pipes on the automatic water supply device respectively. The automatic water supply device is equipped with a slide rod with multiple conical grooves, and multiple annular retaining springs are fitted on the slide rod. Spray heads and irrigation nozzles are fixedly connected to the multiple annular retaining springs respectively.

[0007] Furthermore, the water distribution valve is provided with an inlet chamber with a drain hole, which is located in the middle of the shelf. Directly below the inlet chamber, there are irrigation water storage chamber and spray water storage chamber separated by a partition. The inlet chamber is separated from the irrigation water storage chamber and the spray water storage chamber by the shelf. A valve core is placed on the drain hole, and the valve core is provided with a stopcock, a rotating shaft and a switch.

[0008] Furthermore, each of the aforementioned ring snap rings is internally provided with snap ring holes, springs, washers, and steel balls, and the outer end of the snap ring holes is plugged with screws.

[0009] Furthermore, the suspension is positioned directly above the rotary tiller and the automatic seeder. The first end of the suspension is fixed to a flatbed truck, and the second end is connected to an automatic water supply device. The flatbed truck is equipped with a platform, a water tank, and an intelligent water pump.

[0010] Furthermore, the rotary tiller is connected to the rear of the flatbed truck via a connecting rod. The rotary tiller is mainly equipped with multiple double-headed rotary plows, which are driven by an external drive to obtain rotational force, so as to achieve the effect of deep tillage of the land.

[0011] Furthermore, the automatic seeder is positioned directly behind the rotary tiller and connected to the flatbed truck via a connecting rod. The automatic seeder is equipped with multiple seeders, seed metering and furrowing devices, and a soil covering mechanism.

[0012] The beneficial effects of this utility model are:

[0013] 1. By using an automatic watering device, seeds can be watered promptly after sowing and covering with soil, reducing the traditional steps of watering after sowing, shortening planting time, saving manpower and costs, and improving planting efficiency.

[0014] 2. By using the water distribution valve, two watering modes can be obtained. When the stopcock is above the water storage chamber, the spray watering mode is obtained, and vice versa.

[0015] 3. The conical groove on the slide bar, in conjunction with the ring spring, can effectively fix the sprinkler head and irrigation nozzle. By moving the ring spring to different conical grooves, the sprinkler head and irrigation nozzle can be repositioned to water different areas according to actual planting needs.

Detailed Implementation

[0025] To more clearly and completely illustrate the technical solution of this utility model, the following description is provided in conjunction with the accompanying drawings.

[0026] Please refer to Figure 1 - Figure 8 This utility model proposes an agricultural planting device with sowing and water supply functions, including a flatbed cart 1, a rotary tiller 2, an automatic seeder 3, and an automatic water supply device 4. The flatbed cart 1 is equipped with a platform 10, a water tank 11 fixed on the platform 10, an intelligent water pump 12, and a suspension 13. The flatbed cart 1 has four wheels at its bottom, which are moved by an external traction device. The rotary tiller 2 is connected to the rear of the flatbed cart 1 via a linkage. The rotary tiller 2 is equipped with multiple double-headed reversible plows 20, which are driven synchronously by an external drive via a coupling to achieve deep tillage and soil turning. The double-headed reversible plows 20 simultaneously turn and break up the soil, adapting to various soil types and ensuring more even tillage.

[0027] The automatic seeder 3 is located directly behind the rotary tiller 2 and is connected to the flatbed truck 1 via a connecting rod. The automatic seeder 3 has multiple seed metering and furrow openers 30 at its bottom, and seeders 31 are respectively installed above the seed metering and furrow openers 30. Each seed metering and furrow opener 30 can perform furrow opening operations. Each seeder 31 is equipped with an automatic seed distributing mechanism, which can evenly distribute the seeds inside the seeder 31 into the opened furrows. A soil covering mechanism 32 is respectively installed directly behind the multiple seed metering and furrow openers 30, and the bottom surface of the multiple soil covering mechanisms 32 is slightly higher than the bottom surface of the multiple seed metering and furrow openers 30 to ensure that the seeds are not touched while effectively filling the soil during the soil covering operation.

[0028] An automatic water supply device 4 is located directly behind the automatic seeder 3. The automatic water supply device 4 is equipped with a water distribution valve 6 fixed on the suspension 13. The water distribution valve 6 has a water inlet chamber 60 inside. The water inlet chamber 60 has a water inlet on its side and is connected to the water outlet of the intelligent water pump 12 through a water pipe. The bottom of the water inlet chamber 60 is equipped with a shelf 64 with a reserved drain hole 61. Directly below the shelf 64, a watering water storage chamber 62 and a spray water storage chamber 63 are arranged side by side and separated by a partition 65. The drain hole 61 is located at the center of the junction of the water inlet chamber 60, the watering water storage chamber 62 and the spray water storage chamber 63. The drain hole 61 has a two-layer stepped design and is circular in shape. The bottom hole diameter is smaller than the top hole diameter. A valve core 66 is placed inside the upper hole of the drain hole 61. A semi-circular plug 67 is provided at the lower end of the valve core 66. The thickness and radius of the plug 67 are consistent with the upper height and radius of the drain hole 61, respectively. The bottom of the plug is in contact with the lower surface of the drain hole 61, which can achieve a good sealing effect. A switch 68 is provided at the top of the valve core 66. The valve core 66 is connected to the reserved shaft hole of the partition 65 through the rotating shaft 69. Turning the switch 68 will allow it to rotate along with the plug 67.

[0029] Water outlets are provided on the sides of the irrigation water storage chamber 62 and the spray water storage chamber 63, respectively. The water outlet of the irrigation water storage chamber 62 is connected to the irrigation pipe 45 via a water pipe, and the water outlet of the spray water storage chamber 63 is connected to the spray pipe 44 via a water pipe. The irrigation pipe 45 and the spray pipe 44 are arranged parallel to each other directly behind the slide rod 40, and the two sides of the slide rod 40 are respectively connected to the ends of the suspension 13. Multiple conical slots 41 are evenly distributed in the middle section of the slide rod 40, and starting from one end of the slide rod 40, a ring spring 5 is fitted in every other conical slot 41 to ensure that each ring spring 5 is fitted in the conical slot 41, and empty conical springs 41 are left on both sides of each ring spring 5 until empty conical slots 41 are reserved at both ends of the slide rod 40. The number of ring springs 5 ​​is the same as that of the seed metering and furrowing device 30.

[0030] The annular retaining ring 5 has multiple retaining ring holes 50 evenly distributed around its circumference. A steel ball 54 is first inserted into each retaining ring hole 50, followed by a washer 53 and a spring 52. The washer 53 separates the steel ball 54 and the spring 52. The outermost end of each retaining ring hole 50 is plugged with a screw 51 to prevent the spring 52 from falling out and to ensure that the spring 52 provides continuous elastic force to the steel ball. The diameter of the retaining ring hole 50 at the position of the steel ball 54 is designed to be smaller than the outermost diameter. This design helps to secure the steel ball 54 and prevent it from falling out, and ensures that the annular retaining ring 5 can generate sufficient tightening force during operation.

[0031] Irrigation pipe 45 and sprinkler pipe 44 are simultaneously fixed to multiple support rods and connected to multiple annular retaining springs 5. These annular retaining springs 5 ​​are connected to the same long shaft via multiple connecting rods in a direction perpendicular to the ground. Wheels perpendicular to the ground are installed at both ends of the long shaft, and each wheel is connected to both ends of a slide rod 40 via a bracket. The slide rod 40 has a polygonal design at both ends to effectively prevent the wheels from rotating along its axis. Multiple irrigation nozzles 43 are evenly and vertically distributed directly below the irrigation pipe 45, and multiple sprinkler heads 42 are evenly and vertically distributed directly below the sprinkler pipe 44. All irrigation nozzles 43 and sprinkler heads 42 are perpendicular to the ground, and the number of irrigation nozzles 43 and sprinkler heads 42 matches the number of annular retaining springs 5. All irrigation nozzles 43, sprinkler heads 42, and annular retaining springs 5 ​​are directly facing the seed-opening furrow opener 30. This arrangement ensures that water is entirely distributed around the furrowed planting area, preventing water waste.

[0032] Before sowing, the relevant parameters of the intelligent water pump 12 need to be set in advance according to the soil moisture and the actual amount of water required for irrigation. The valve core 66 on the water distribution valve 6 is manually rotated to the desired position. For example, if irrigation is needed, the switch 68 is rotated to the irrigation position. At this time, the stopcock 67 is rotated to the position of the spray water storage chamber 63, blocking the drain hole 61 near the spray water storage chamber 63, while the drain hole 61 in the irrigation water storage chamber 62 is open. Similarly, when spray mode is needed, simply rotate the switch 68 to the spray position. Moving the annular retaining spring 5 to the adjacent conical retaining groove 41 allows simultaneous movement of the irrigation nozzle 43 and the spray head 42, achieving the purpose of changing the irrigation position.

[0033] As the flatbed truck 1 is towed, the rotary tiller 2 begins operation. After the land is evenly tilled, the automatic seeder 3 follows closely, using multiple seeders 30 to open furrows in the tilled land. Simultaneously, multiple seeders 31 begin sowing, and then multiple soil covering mechanisms 32 fill the furrows after sowing. While the tilling and sowing are complete, the automatic water supply device 4 begins watering. First, the intelligent water pump 12 draws water from the water tank 11 through a water pipe and sends it into the water inlet chamber 60. Then, the water in the water inlet chamber 60 is introduced into the irrigation storage chamber 62 or the spray storage chamber 63. The water then flows through the outlet of the irrigation storage chamber 62 or the spray storage chamber 63 into the irrigation pipe 45 or the spray pipe 44, and is evenly distributed to the irrigation nozzles 43 or the spray heads 42, ultimately watering the land.

[0034] In this embodiment, the watering method and amount can be set according to the actual land environment and planting requirements. Water pressure and flow rate per minute can be precisely controlled by adjusting the relevant parameters of the intelligent water pump 12. The irrigation mode and spraying mode can be switched by adjusting the switch 68 of the water distribution valve 6. The combined use of the ring spring 5 and the conical groove 41 allows for changing the watering position. Relatively simple mechanisms are used to automate the cumbersome agricultural planting process, improving planting efficiency, avoiding excessive labor waste, and saving costs.

[0035] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
