Description

Technical Field

[0001] This application relates to the technical field of drip irrigation tapes, and more particularly, to a drip irrigation tape laying device. Background Art

[0002] A drip irrigation tape is a modern irrigation device mainly used for agricultural irrigation and horticulture. It directly delivers water to the roots of plants through evenly distributed small holes on the tape, thereby effectively reducing water evaporation and leakage. The design of the drip irrigation tape enables it to flexibly adjust the water volume according to the needs of plants, and its high water resource utilization rate also helps to save water and increase crop yields. In addition, the drip irrigation system can reduce weed growth and the risk of pests and diseases, contributing to the realization of sustainable agricultural development.

[0003] In the prior art, when laying a drip irrigation tape, if the burial depth is too shallow, problems such as water, fertilizer, and air loss will occur. Water is easily evaporated in the soil, especially in dry and high-temperature environments, and this phenomenon is more obvious. If buried too deep, it will affect the permeability of water and fertilizer in the drip irrigation tape, thereby reducing the soil fertility. In addition, when the burial depth of the drip irrigation tape is unreasonable, it will also lead to a decrease in soil aeration, affecting root respiration and being unfavorable to the healthy growth of crops.

[0004] According to the geographical environment, in some areas, the drip irrigation tape needs to be shallowly buried to prevent the loss of water, fertilizer, and air, and to make the water and fertilizer maintenance cycle long. In reality, most of the drip irrigation tapes are shallowly buried manually. Although it can effectively save water and improve irrigation efficiency, due to the relatively shallow burial of the drip irrigation tape, some buried sections are buried too deep.

[0005] In summary, there is a need to provide an improved technical solution to address the above deficiencies in the prior art to accurately control the burial depth of the drip irrigation tape. Summary of the Invention

[0061] In an implementable manner, the soil loosening part further includes a soil guiding backing plate 16. The soil guiding backing plate 16 is arranged on the top of the housing, and the upper surface of the soil guiding backing plate 16 is a soil guiding surface.

[0062] Specifically, as Figure 7 shown, the middle line of the soil guiding surface bulges upward, and the rear end of the middle line is higher than the front end. Through the arrangement of the soil guiding backing plate 16, the soil scatters to both sides after passing through the soil guiding backing plate 16.

[0063] In an implementable manner, as Figure 7As shown, three arc grooves are provided on the bottom surface of the soil guiding backing plate 16, and the three arc grooves are evenly distributed in the width direction. An adjusting column 15 is provided below the soil guiding backing plate 16. When the adjusting column 15 is arranged in the arc groove in the middle, the soil guiding backing plate 16 remains horizontal, and the soil will scatter evenly to both sides. When the adjusting column 15 is arranged in the arc groove on the left side, the left side of the soil guiding backing plate 16 is higher than the right side, and most of the soil will scatter to the right side. When the adjusting column 15 is arranged in the arc groove on the right side, the right side of the soil guiding backing plate 16 is higher than the left side, and most of the soil will scatter to the left side. By arranging the adjusting column 15, it is adapted to the paved ground with different slopes.

[0064] In an implementable manner, as Figure 7 shown, an extension support plate 20 is provided at the rear side of the soil guiding backing plate 16, and auxiliary guide wheels 21 are provided on both sides of the extension support plate 20.

[0067] When this application is in use, it includes the following content:

[0068] Before working, adjust the downward extension length of the depth adjustment rod 4 to control the depth of the blade 7. By sliding the slider 5 into the corresponding positioning groove, the position of the blade 7 is fixed. The blade 7 assists the conical soil-breaking block 8 to complete the soil-breaking and soil-loosening operations.

[0069] The second reversing gear is controlled by the servo motor 14 to rotate, and the second reversing gear drives the first reversing gear 6 to rotate, adjusts the angle of the soil-breaking drill bit 8, adjusts the depth of the soil-breaking and soil-loosening operations, the drip irrigation tape passes through the loosened soil, and then drives the soil-breaking drill bit 8 to make a downward angle adjustment.

[0070] Adjust the position of the adjusting column 15 under the soil guiding backing plate 16 to make the soil guiding backing plate 16 generate an inclination angle, so that during the operation, the soil can scatter to the predetermined side under the action of gravity.

[0071] Turn on the second motor 18 to drive the power wheel shaft 19 to provide forward power for the equipment, or fix the traction rope in the traction ring 1 and pull the equipment for operation by the front-end machinery.

[0072] After the first motor 10 rotates, it drives through the universal joint rod 11 to ensure that the earth-breaking drill bit 8 can rotate at any angle, and cooperates with the conical earth-breaking block 8 to complete the earth-breaking and soil-loosening operations.

[0073] During the operation process, the extension support plate 20 and the auxiliary guide wheel 21 cooperate above the ground surface to ensure support with the power wheel shaft 19.

[0074] The soil after soil loosening and earth breaking is driven by the backfill plate 26 and backfilled into the laying trench.

[0075] In summary, the present application can accurately control the embedding depth of the drip irrigation tape according to specific requirements. By adjusting the angle of the earth-breaking drill bit, the depth of the earth-breaking and soil-loosening operations can be adjusted. By adjusting the depth of the downward extension of the shovel blade, the shovel blade can assist the earth-breaking drill bit in earth-breaking and soil-loosening. Moreover, through earth-breaking and soil-loosening, it is beneficial for the water and fertilizer of the drip irrigation tape to penetrate into the soil, preventing the waste of water and fertilizer caused by their loss into the air.

[0076] The present application adopts an assembled structure to achieve an overall integrated operation. At the same time, it can also cooperate with relevant equipment for operation, performing single-function or combined progressive operations, and the working surface is more flexible; the overall equipment adopts mechanization and can also cooperate with relevant equipment for operation.
