Description

Technical Field

[0001] This invention belongs to the field of agricultural technology and relates to an agricultural soil irrigation device that can rotate at any angle. Background Technology

[0002] Existing technologies have some drawbacks when it comes to seed irrigation: large-scale spraying cannot achieve precise spraying of the soil deep around the seeds, and some water and fertilizer will be wasted; at the same time, if hot weather occurs, the sprayed water and fertilizer will evaporate, resulting in the loss of some water and fertilizer, thus causing the seeds to not receive enough water and fertilizer irrigation.

[0003] To address the aforementioned shortcomings of existing technologies, an agricultural soil irrigation device capable of rotating at any angle has been developed. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural soil irrigation device that can rotate at any angle.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An agricultural soil irrigation device that can rotate at any angle includes an annular support driven by a rotary hydraulic cylinder, the rotary hydraulic cylinder being connected to a swing arm of an agricultural machine, a collar being fixedly connected to the inner cavity of the annular support, a sliding rod extending to the top of the annular support being slidably connected to the bottom of the collar, a rotating cylinder being rotatably connected to the bottom of the collar and fitted onto the surface of the sliding rod, a cone being fixedly connected to the bottom of the rotating cylinder, and the rotating cylinder being driven to rotate below the collar by a driving device;

[0007] The sliding rod has a flow hole in its inner cavity that communicates with an external nutrient solution delivery pipe. The sliding rod also has an injection port on its side that communicates with the flow hole. A conical block adapted to the inner cavity of the cone is rotatably connected to the bottom of the sliding rod. A connecting rod is fixedly connected to the bottom of the conical block. One end of the connecting rod penetrates and extends into the inner cavity of the cone. The inner cavity of the cone has a connecting groove adapted to the connecting rod. The surface of the cone is flush with the end of the connecting rod. The surface of the sliding rod has a concave section. A piston sealing ring, which is slidably connected to the inner cavity of the rotating cylinder, is fixedly connected to the surface of the concave section. A limiting ring located above the piston sealing ring is fixedly connected to the inner cavity of the rotating cylinder. The limiting ring is circumferentially fitted onto the surface of the concave section. A sealing ring is fixedly connected to the top of the sliding rod.

[0008] A reset structure is provided at the top of the sliding rod.

[0009] During use, the agricultural machinery is moved to the irrigation point, and the ring support is moved above the irrigation point. Then, the hydraulic cylinder rotates the ring support to the appropriate angle. At this time, the drive arm of the agricultural machinery lowers the ring support, and the rotating cylinder and cone at the bottom are inserted into the soil around the seeds. At this time, the motor drives the gear ring to rotate, which in turn drives the rotating cylinder and cone to rotate. The cone, through the cooperation of the insertion rod and the insertion groove, drives the cone block at the bottom of the sliding rod to rotate. As it is inserted into the soil, it rotates continuously, loosening the soil and preventing it from becoming compacted and affecting subsequent nutrient absorption. When the fertilization point inside the soil is reached, this... Nutrient solution is injected through the nutrient solution delivery pipe. The nutrient solution flows out from the injection port and enters between the rotating cylinder and the sliding rod. Then, pressure is applied to the piston sealing ring, pushing the piston sealing ring to drive the sliding rod to move upward within the rotating cylinder and the collar. At this time, the insertion rod at the bottom of the cone block is pulled out from the insertion groove of the cone head. At this time, a gap exists, and the high-pressure nutrient solution is sprayed from the insertion groove into the soil. At this time, due to the pressure reduction, the tension spring pushes the sliding rod downward to reset, increasing the pressure on the nutrient solution and making its injection effect better. Then, the operation is repeated to continuously pressurize and discharge the nutrient solution for effective nutrient solution irrigation, and it can effectively prevent internal blockage when inserting into the soil.

[0010] Furthermore, the surfaces of both the rotating cylinder and the cone are provided with spiral patterns to facilitate piercing the soil and inserting it deep into the soil.

[0011] The driving device includes a gear ring rotatably mounted below the annular support. The gear ring is driven by a gear driven by a motor. A gear that abuts against the inner cavity of the gear ring is fixedly connected to the surface of the rotating cylinder. The motor drives the gear ring to rotate, which in turn drives the rotating cylinder to rotate, causing the rotating cylinder and the cone to rotate. As the cone is inserted into the soil, it rotates continuously to loosen the soil and prevent it from becoming compacted and affecting subsequent nutrient absorption.

[0012] The collar is provided in multiples and is arranged in a ring-shaped array within the inner cavity of the ring support.

[0013] The reset structure includes a fixing block fixedly connected to the top of the sliding rod. A tension spring is sleeved on the surface of the sliding rod located between the annular bracket and the fixing block. The bottom end of the tension spring is fixedly connected to the top of the annular bracket, and the top end of the tension spring is fixedly connected to the bottom of the fixing block.

[0014] The plug rods are provided in multiple locations and are evenly distributed at the bottom of the conical block, allowing for multi-point grouting and better grouting effect.

[0015] The surface of the plug rod is fixedly connected to a sealing gasket that abuts against the end of the plug groove, thereby sealing the cavity and forming a relatively closed cavity.

[0016] During use, the nutrient solution flows out from the injection port and enters between the rotating cylinder and the sliding rod. Pressure is then applied to the piston sealing ring, pushing it to move the sliding rod upwards within the rotating cylinder and collar. This causes the insertion rod at the bottom of the conical block to be pulled out of the insertion slot of the cone head. A gap exists, and the high-pressure nutrient solution is sprayed from the insertion slot into the deep soil. Simultaneously, due to the reduced pressure, the tension spring pushes the sliding rod downwards to reset, increasing the pressure on the nutrient solution and improving its injection effect. This process is repeated, continuously increasing pressure and effectively discharging the nutrient solution for irrigation. This also effectively prevents internal blockage when inserting the nutrient solution into the soil. The rotation of the rotating cylinder drives the rotating cylinder and the cone head to rotate, continuously rotating as it is inserted into the soil, loosening the soil and preventing compaction that could hinder subsequent nutrient absorption. Furthermore, the rotating connection of the conical block does not affect normal drainage.

[0017] Compared with the prior art, the device of the present invention is simple to operate, has a good injection effect, and can effectively prevent internal blockage when inserted into the soil. Attached Figure Description

[0023] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] like Figure 1-4The agricultural soil irrigation device shown includes an annular support 2 driven by a rotary hydraulic cylinder 1, the rotary hydraulic cylinder 1 being connected to the swing arm of an agricultural machine, a collar 3 being fixedly connected to the inner cavity of the annular support 2, a sliding rod 7 extending above the annular support 2 being slidably connected to the bottom of the collar 3, a rotating cylinder 4 being rotatably connected to the bottom of the collar 3 and sleeved on the surface of the sliding rod 7, a cone head 14 being fixedly connected to the bottom of the rotating cylinder 4, and the rotating cylinder 4 being driven to rotate below the collar 3 by a driving device.

[0025] The sliding rod 7 has a flow hole 11 in its inner cavity that communicates with the external nutrient solution delivery pipe 10. The sliding rod 7 has an injection port 12 in its side that communicates with the flow hole 11. The bottom of the sliding rod 7 is rotatably connected to a conical block 13 that is adapted to the inner cavity of the cone head 14. The bottom of the conical block 13 is fixedly connected to a plug rod 16. One end of the plug rod 16 passes through and extends into the inner cavity of the cone head 14. The inner cavity of the cone head 14 has a plug groove 15 that is adapted to the plug rod 16. The surface of the cone head 14 is flush with the end of the plug rod 16. The surface of the sliding rod 7 has a concave section 18. The surface of the concave section 18 is fixedly connected to a piston sealing ring 17 that is slidably connected to the inner cavity of the rotating cylinder 4. The inner cavity of the rotating cylinder 4 is fixedly connected to a limiting ring 19 located above the piston sealing ring 17. The limiting ring 19 is circumferentially sleeved on the surface of the concave section 18. The top of the sliding rod 7 is fixedly connected to a sealing ring 20.

[0026] The top of the sliding rod 7 is equipped with a reset structure. During use, the agricultural machinery is moved to the irrigation point, driving the ring support 2 to move above the irrigation point. Then, the rotating hydraulic cylinder 1 drives the ring support 2 to rotate to the appropriate angle. At this time, the driving arm of the agricultural machinery lowers the ring support 2, and the bottom rotating cylinder 4 and cone 14 are inserted into the soil around the seeds. Simultaneously, the motor drives the gear ring 6 to rotate, which in turn drives the rotating cylinder 4 and cone 14 to rotate. The cone 14, through the cooperation of the insertion rod 16 and the insertion groove 15, drives the cone block 13 at the bottom of the sliding rod 7 to rotate. As it is inserted into the soil, it continuously rotates, loosening the soil and preventing it from becoming compacted and affecting subsequent nutrient absorption. When drilling into the soil... After the fertilizer is applied, nutrient solution is injected through the nutrient solution delivery pipe 10. The nutrient solution flows out from the injection port 12 and enters between the rotating cylinder 4 and the sliding rod 7. Then, pressure is applied to the piston sealing ring 17, which pushes the piston sealing ring 17 to drive the sliding rod 7 to move upward within the rotating cylinder 4 and the collar 3. At this time, the insertion rod 16 at the bottom of the cone block 13 is pulled out from the insertion groove 15 of the cone head 14. At this time, there is a gap, and the high-pressure nutrient solution is sprayed from the insertion groove 15 into the soil depth. At this time, due to the pressure reduction, the tension spring 8 pushes the sliding rod 7 to return to its original position downward, increasing the pressure on the nutrient solution and making its injection effect better. Then, the operation is repeated to continuously pressurize and discharge the nutrient solution for effective nutrient solution irrigation, and can effectively prevent internal blockage when inserted into the soil.

[0027] Both the rotating cylinder 4 and the cone 14 have spiral patterns on their surfaces, which facilitates piercing the soil and inserting it deep into the soil.

[0028] The driving device includes a gear ring 6 rotatably mounted below the annular support 2. The gear ring 6 is driven by a gear driven by a motor. A gear 5 is fixedly connected to the surface of the rotating cylinder 4 and abuts against the inner cavity of the gear ring 6. The motor drives the gear ring 6 to rotate, which in turn drives the rotating cylinder 4 to rotate, thereby causing the rotating cylinder 4 and the cone head 14 to rotate. When the cone head 14 is inserted into the soil, it rotates continuously to loosen the soil and prevent it from becoming compacted and affecting subsequent nutrient absorption.

[0029] Multiple collars 3 are provided and are arranged in a ring-shaped row inside the annular support 2.

[0030] The reset structure includes a fixing block 9 fixedly connected to the top of the sliding rod 7. A tension spring 8 is sleeved on the surface of the sliding rod 7 between the annular bracket 2 and the fixing block 9. The bottom end of the tension spring 8 is fixedly connected to the top of the annular bracket 2, and the top end of the tension spring 8 is fixedly connected to the bottom of the fixing block 9.

[0031] Multiple plug rods 16 are provided and evenly distributed at the bottom of the conical block 13, allowing for multi-point grouting and better grouting effect.

[0032] A sealing gasket is fixedly connected to the surface of the plug rod 16, which is abutted by the end of the plug groove 15, and the sealing gasket is used to form a relatively closed cavity.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
