Description

Technical Field

[0001] The utility model relates to the technical field of water and fertilizer application equipment, in particular to a water and fertilizer application equipment buried in farmland soil. Background Art

[0002] Irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, insufficient or unevenly distributed precipitation often cannot meet the water requirements of crops. Therefore, artificial irrigation is necessary to make up for the lack of natural rainfall.

[0003] Irrigation equipment is divided into two types: above-ground and underground. Above-ground irrigation means that water pipes and sprinklers are installed above the ground to spray water on the surface of plants, while underground irrigation systems mean that water pipes and sprinklers are located below the soil layer to apply water and fertilizer directly to the roots of plants.

[0004] However, after the water and fertilizer application equipment is buried in the soil layer, the liquid outlet of the equipment is at risk of being blocked by the soil, and the pressure in the soil layer or when field workers step on the equipment will cause the equipment pressure to increase, and the equipment is at risk of being damaged due to excessive pressure; therefore, it does not meet the existing needs. In this regard, we propose a water and fertilizer application equipment buried in farmland soil. Utility Model Content

[0005] The purpose of the present utility model is to provide a water and fertilizer application device buried in farmland soil, so as to solve the problems raised in the above-mentioned background technology that after the water and fertilizer application device is buried in the soil layer, the liquid outlet port of the device is at risk of being blocked by the soil, and the pressure in the soil layer or when field workers step on the device will cause the pressure of the device to increase, and the device is at risk of being damaged due to excessive pressure.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figures 1 to 4 As shown, a water and fertilizer application equipment buried in farmland soil, an irrigation box 2 is installed at one end of the delivery pipe 1, the end of the delivery pipe 1 passes through the end of the irrigation box 2 and is inserted into the inside of the irrigation box 2, the end of the delivery pipe 1 and the irrigation box 2 are fixed with sealant, a plurality of irrigation nozzles 6 are inlaid and fixed on both sides of the irrigation box 2 in a rectangular array, a connecting hose 7 is fixed on the outer end of the irrigation nozzle 6, the top of the irrigation box 2 is covered with a protective cover 3, a plurality of liquid outlet holes 5 are distributed in a rectangular array on both sides of the protective cover 3, one end of the connecting hose 7 is inserted into the inner side of the liquid outlet hole 5, end sealing plates 4 are provided between both ends of the protective cover 3 and both ends of the irrigation box 2, the end sealing plates 4 are made of rubber, the ends of the irrigation box 2 and the protective cover 3 are sealed by the end sealing plates 4, and the irrigation box 2 is protected by the protective cover 3 covering the top of the irrigation box 2 to prevent the soil pressure from directly acting on the irrigation box 2 and causing damage to the irrigation box 2.

[0022] The liquid outlet 5 is in an inclined state, and the end position of the liquid outlet 5 located on the inner side of the protective cover 3 is higher than the end position of the liquid outlet 5 located outside the protective cover 3. The inclined liquid outlet 5 can ensure that soil will not enter the liquid outlet 5 and cause blockage of the liquid outlet 5 as a whole. The soil can only partially enter the bottom end of the liquid outlet 5.

[0023] The end of the connecting hose 7 connected to the liquid outlet 5 is inserted into the end of the liquid outlet 5 located on the inner side of the protective cover 3. The outer side of the end of the connecting hose 7 connected to the liquid outlet 5 is provided with an anti-slip filling end block 11. The anti-slip filling end block 11 is made of rubber. The anti-slip filling end block 11 is bonded and fixed to the connecting hose 7 and the liquid outlet 5 by adhesive. The anti-slip filling end block 11 is used to connect the connecting hose 7 to the liquid outlet 5 and ensure that the end of the connecting hose 7 cannot be separated from the inner side of the end of the liquid outlet 5, thereby ensuring that water and fertilizer flow along the liquid outlet 5 to the outside of the protective cover 3.

[0024] A plurality of buffer springs 8 distributed in a rectangular array are provided between the bottom surface of the protective cover 3 and the upper surface of the irrigation box 2. The length of the buffer spring 8 near the middle of the protective cover 3 is longer than the length of the buffer spring 8 near the side of the protective cover 3. A second positioning column 10 is provided on the inner side of the top end of the buffer spring 8. The top end of the second positioning column 10 is fixed to the bottom surface of the protective cover 3. A first positioning column 9 is provided on the inner side of the bottom end of the buffer spring 8. A damping rod 12 is fixed between the first positioning column 9 and the second positioning column 10. The bottom end of the first positioning column 9 is fixed to the upper surface of the irrigation box 2. The buffer spring 8 and the damping rod 12 perform elastic buffering between the protective cover 3 and the irrigation box 2 to prevent the protective cover 3 and the irrigation box 2 from contacting each other, and provide elastic support for the protective cover 3, so as to reduce the pressure of the soil layer on the protective cover 3, thereby reducing the chance of damage to the protective cover 3.

[0025] Working principle: First, place the irrigation box 2 in the soil layer, then place the buffer spring 8 on the upper surface of the irrigation box 2, then cover the protective cover 3 on the top of the irrigation box 2, use the end sealing plate 4 to seal the ends of the irrigation box 2 and the protective cover 3, and then backfill the soil to cover the protective cover 3. When the soil is backfilled, the pressure impact acts on the surface of the protective cover 3. At this time, the protective cover 3 moves downward and compresses the buffer spring 8 and the damping rod 12. The buffer spring 8 and the damping rod 12 are used to buffer the downward movement of the protective cover 3, and at the same time, the soil exerts pressure on the surface of the protective cover 3. The partial pressure is buffered to prevent the irrigation box 2 from being damaged due to the impact of soil pressure. After the equipment is installed, when the equipment is used to apply water and fertilizer to the land, the water and fertilizer are sent into the irrigation box 2 through the delivery pipe 1. After the water and fertilizer fill the inside of the irrigation box 2, under the high pressure formed by the external pump, the water and fertilizer are transported into the inner side of the liquid outlet 5 through the irrigation nozzle 6 and the connecting hose 7. The water and fertilizer flow downward along the inclined liquid outlet 5 and enter the soil layer from the bottom end of the liquid outlet 5. The inclined liquid outlet 5 can prevent the port of the connecting hose 7 from being blocked, ensuring that the use of the equipment will not be affected after it is buried in the soil layer.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
