Description

Technical Field

[0001] The invention belongs to the technical field of agriculture and relates to an agricultural soil watering device whose watering equipment body can be rotated at any angle. Background Art

[0002] The existing technology has some defects in seed irrigation: large-scale spraying cannot achieve accurate spraying of the soil deep around the seeds, and some water and fertilizer will be wasted; at the same time, if it encounters hot weather, the sprayed water and fertilizer will be evaporated, and some water and fertilizer will be lost, resulting in the problem that the seeds do not get enough water and fertilizer irrigation.

[0003] In order to solve the above-mentioned defects in the prior art, an agricultural soil irrigation device that can rotate at any angle has been developed. Summary of the invention

[0004] The purpose of the invention is to provide an agricultural soil watering device which can be rotated at any angle.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: An agricultural soil irrigation device that can rotate at any angle, comprising an annular bracket driven by a rotating hydraulic cylinder, the rotating hydraulic cylinder is connected to an agricultural machinery swing arm, a collar is fixedly connected to the inner cavity of the annular bracket, a sliding rod extending to the top of the annular bracket is slidably connected to the bottom of the collar, a rotating cylinder sleeved on the surface of the sliding rod is rotatably connected to the bottom of the collar, a cone head is fixedly connected to the bottom of the rotating cylinder, and the rotating cylinder is driven to rotate below the collar by a driving device; The inner cavity of the sliding rod is provided with a flow hole connected to an external nutrient solution delivery pipeline, and the side of the sliding rod is provided with an injection port connected to the flow hole, the bottom of the sliding rod is rotatably connected to a conical block adapted to the inner cavity of the cone head, the bottom of the conical block is fixedly connected to a plug-in rod, one end of the plug-in rod passes through and extends to the inner cavity of the cone head, the inner cavity of the cone head is provided with a plug-in groove adapted to the plug-in rod, the surface of the cone head is flush with the end of the plug-in rod, the surface of the sliding rod is provided with a concave section, the surface of the concave section is fixedly connected to a piston sealing ring slidably connected to the inner cavity of the rotating cylinder, the inner cavity of the rotating cylinder is fixedly connected to a limiting ring located above the piston sealing ring, the limiting ring is circumferentially sleeved on the surface of the concave section, and the top of the sliding rod is fixedly connected to a sealing ring; A reset structure is arranged on the top of the sliding rod.

[0006] When in use, the agricultural machine is moved to the point where irrigation is required, and the annular bracket is driven to move above the irrigation point. The annular bracket is then driven to rotate to an appropriate angle by rotating the hydraulic cylinder. At this time, the driving arm of the agricultural machine drives the annular bracket to descend, and the rotating cylinder and the cone head at the bottom are inserted into the soil around the seeds. At this time, the motor drives the gear ring to rotate, drives the rotating cylinder to rotate, and drives the rotating cylinder and the cone head to rotate. The cone head drives the cone block at the bottom of the sliding rod to rotate through the cooperation of the plug rod and the plug groove. When it is inserted into the soil downward, it rotates continuously to loosen the soil to prevent it from being compressed and compacted and affecting subsequent nutrient absorption. After drilling to the fertilization point inside the soil, this When the 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, and then pressure is applied to the piston sealing ring to push the piston sealing ring to drive the sliding rod to move upward in the rotating cylinder and the sleeve ring. At this time, the plug-in rod at the bottom of the cone block is pulled out from the plug-in groove of the cone head. At this time, there is a gap, and the high-pressure nutrient solution is sprayed from the plug-in groove into the deep soil. At this time, because the pressure is reduced, the tension spring pushes the sliding rod to reset downward, increasing the pressure on the nutrient solution and making it more effective in injection. Then the operation is repeated, and the pressure is continuously increased and discharged to effectively irrigate the nutrient solution, and it can effectively prevent internal blockage when plugging into the soil.

[0007] Furthermore, the surfaces of the rotating cylinder and the cone head are provided with spiral patterns to facilitate piercing the soil and inserting into the deep soil.

[0008] The driving device includes a gear ring rotatably arranged under the annular bracket, the gear ring is driven by a gear driven by a motor, and the surface of the rotating cylinder is fixedly connected with a gear abutting against the inner cavity of the gear ring. The motor drives the gear ring to rotate, drives the rotating cylinder to rotate, drives the rotating cylinder and the cone head to rotate, and continuously rotates when inserted downward into the soil to loosen the soil and prevent it from being compressed and compacted and affecting subsequent nutrient absorption.

[0009] The rings are provided in plurality and are distributed in an annular arrangement in the inner cavity of the annular support.

[0010] The reset structure includes a fixed block fixedly connected to the top of the sliding rod, and a tension spring is sleeved on the surface of the sliding rod between the annular bracket and the fixed 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 fixed block.

[0011] A plurality of the plug-in rods are provided and are evenly distributed at the bottom of the conical block, so that multi-point pouring can achieve a better pouring effect.

[0012] The surface of the plug-in rod is fixedly connected with a sealing gasket abutted by the end of the plug-in groove, and the sealing is performed by the sealing gasket to form a relatively closed cavity.

[0013] During use, the nutrient solution flows out from the injection port and enters between the rotating cylinder and the sliding rod, and then pressure is applied to the piston sealing ring, which pushes the piston sealing ring to drive the sliding rod to move upward in the rotating cylinder and the sleeve ring, and at this time, the plug-in rod at the bottom of the cone block is pulled out from the plug-in groove of the cone head. At this time, there is a gap, and the high-pressure nutrient solution is sprayed from the plug-in groove to the deep soil. At this time, because the pressure is reduced, the tension spring pushes the sliding rod to reset downward, increasing the pressure on the nutrient solution and making its injection effect better. Then the operation is repeated, and the pressure is continuously increased and discharged to effectively irrigate the nutrient solution, and internal blockage can be effectively prevented when plugged into the soil; the rotating cylinder is rotated to drive the rotating cylinder and the cone head to rotate, and it rotates continuously when plugged into the soil downward to loosen the soil to prevent it from being compressed and compacted and affecting subsequent nutrient absorption, and the setting of the rotating connecting cone block will not affect normal drainage.

[0014] Compared with the prior art, the device of the present invention is easy to operate, has a good injection effect, and can effectively prevent internal blockage when inserted into the soil. BRIEF DESCRIPTION OF THE DRAWINGS
