Gas pipe device of soil maintaining device for saline and alkaline land

Abstract

The invention discloses a gas pipe device of a soil maintaining device for saline and alkaline land. The gas pipe device comprises a main gas pipe body, and the outer end of an outlet of the main gas pipe body is sleeved with an auxiliary gas pipe body. The auxiliary gas pipe body comprises a first tilting part, one end of the first tilting part is fixedly connected with the outer wall of the main gas pipe body, and the diameter of the end of the first tilting part is gradually increased towards the other end of the first tilting part. The first tilting part extends to be provided with an auxiliary pipe straight pipe part. The other end of an auxiliary pipe main pipe part extends to be provided with a second tilting part. The diameter of the second tilting part is gradually decreased from the end, connected with the auxiliary pipe main pipe part, of the second tilting part to the other end of the second tilting part. The other end of the second tilting part extends to be provided with an auxiliary pipe outlet. By the adoption of the gas pipe device, the speed for gas to flow out can be effectively decreased, flowing-out gas pressure is reduced, and damage to plants and equipment due to excessively-high gas pressure is prevented.

Description

technical field [0001] The invention relates to a trachea device of a soil maintenance device for saline-alkali land, belonging to the field of mechanical equipment. Background technique [0002] In agricultural production, a large part of the land has not been well utilized due to its own land properties, especially in saline-alkali land, because of the high salt content in the soil, many crops cannot survive, and land resources have to be wasted. [0003] A large part of the saline-alkali land is muddy, and this part of the soil is more unfavorable for crop production due to its characteristics. In order to improve it, it is often necessary to aerate to evaporate the water in the soil. The difference in outlets leads to excessive air pressure in some outlets, which damages the air pipe equipment and makes mud splash, which is not conducive to use. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a trachea devic...

[0002] In agricultural production, a large part of the land has not been well utilized due to its own land properties, especially in saline-alkali land, due to the high salt content in the soil, many crops cannot survive, and land resources have to be wasted

[0003] A large part of the saline-alkali land is muddy, and this part of the soil is more unfavorable to the production of crops due to its characteristics. In order to improve it, it is often necessary to aerate to evaporate the water in the soil. Different outlets lead to excessive air pressure at some outlets, causing damage to the trachea equipment and causing mud to splash, which is not conducive to use
