Description

Technical Field

[0001] The invention relates to an irrigation device for saline-alkali land treatment, belonging to the technical field of saline-alkali land treatment. Background Art

[0002] Salt-alkali land management, also known as salt-alkali land improvement, is the transformation and utilization of saline soil, alkaline soil and salinized land. The fundamental reason for the formation of saline-alkali soil is the poor water condition. The salt and alkali in the soil gradually accumulate on the soil surface with the evaporation of water, forming saline-alkali land. In addition, unreasonable irrigation, poor drainage, and excessively high groundwater levels will also aggravate the formation of saline-alkali land. The management of saline-alkali land should follow the principle of adapting measures to local conditions and comprehensive measures. According to the type, degree, geographical location and other factors of saline-alkali land, a scientific and reasonable management plan should be formulated. The management of saline-alkali land will continue to develop in the direction of scientific, precise and efficient. On the one hand, it is necessary to strengthen the research and development and promotion of saline-alkali land management technology to improve the efficiency and effect of management; on the other hand, it is necessary to strengthen the protection and utilization of saline-alkali land resources to achieve the organic combination of saline-alkali land management and sustainable agricultural development. In summary, saline-alkali land management is a long-term and arduous task that requires joint efforts and collaboration from the government, scientific research institutions, enterprises and farmers. By adopting comprehensive measures and promoting saline-alkali land management in accordance with local conditions, we can gradually improve the ecological environment and production conditions of saline-alkali land, and provide strong guarantees for sustainable agricultural development and food security.

[0003] Saline-alkali land is mainly formed due to the evaporation of water and the retention of salt. The treatment of saline-alkali land is mainly carried out through irrigation.

[0029] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0030] like Figure 1-6 As shown, the irrigation device for saline-alkali land treatment comprises:

[0031] A box body 1, wherein a spray mechanism is fixedly installed on the top of the box body 1, a lifting mechanism is fixedly installed on the side wall of the box body 1, and a conveying mechanism is fixedly installed on the outer wall of the box body 1 on the same side of the lifting mechanism;

[0033] The spray mechanism includes a first water pump 4 and a connecting seat 5, both of which are fixedly connected to the top of the box body 1, the top of the connecting seat 5 is connected to the nozzle 6, and the first water pump 4 is connected to the inside of the connecting seat 5 through a connecting pipe 7; a bottom plate 2 is fixedly installed on the top of the box body 1, the bottom of the bottom plate 2 is rotatably connected to the roller 3, and one side of the bottom plate 2 is provided with a notch for the corresponding distribution of the drilling assembly; the lifting mechanism includes a support plate 8, the support plate 8 is fixedly installed to the top of the box body 1, the top of the support plate 8 is fixedly connected to the lifting motor 9, and the support plate 8 and the bottom plate 2 are rotatably connected to the two ends of the lead screw 10 respectively, and the lead screw 10 is connected to the lifting motor 9. The output end of the motor 9 is fixedly connected; there are two lead screws 10, and the two lead screws 10 are both threadedly sleeved with the internal thread of the slide 11, and the slide 11 is respectively fixedly connected to the two ends of the cross plate 12, and a driving mechanism is fixedly installed on the surface of the cross plate 12, and the tops of the two lead screws 10 are fixedly connected to the first pulley 13, and the first pulleys 13 are connected by a first belt 14; the driving mechanism includes a second driving motor 18, and the driving motor 18 is fixedly installed to the middle of the bottom end of the cross plate 12, and the output end of the driving motor 18 and the top of the drilling assembly are fixedly connected to the second pulley, and the second pulleys are connected by a second belt 20.

[0034] In the present technical solution, the first water pump 4 is started to draw water out of the box body 1 and transport it to the inside of the connecting seat 5 through the connecting pipe 7, and the water is sprayed out through the nozzle 6 to achieve the elution of the surface layer of the saline-alkali land, and the box body 1 is moved by the roller 3 on the bottom plate 2, so as to improve the convenience of using the irrigation device; after the device is moved to the specified position, the lifting motor 9 is started to drive the screw 10 to rotate between the support plate 8 and the bottom plate 2, and the screw 10 drives the slide 11 and the cross plate 12 to descend, and then drives the drilling assembly to descend to achieve the drilling process, and the two drilling assemblies are driven simultaneously through the transmission of the second belt 20 and the second pulley.

[0035] The conveying mechanism includes a second water pump 15, which is fixedly mounted to the bottom side wall of the box body 1. The second water pump 15 is connected to the inside of a sleeve 17 through a hose 16. The sleeve 17 is fixedly mounted to the bottom of the cross plate 12, and the sleeve 17 is movably connected to the top surface of the drilling assembly.

[0036] In the present technical solution, after the drilling assembly drills to the specified depth, the second water pump 15 is started to pump out water and transport it to the inside of the sleeve 17 through the hose 16. The sleeve 17 and the drill pipe 21 are always in a sealed rotation, and the rotation of the drill pipe 21 inside the sleeve 17 is not affected. The water source enters the drill pipe 21 from the circular hole at the drill pipe 21, thereby realizing water transportation.

[0037] The drilling assembly includes a drill pipe 21, which is rotatably connected to the inside of the cross plate 12. A circular hole located inside the sleeve shaft 17 is opened on the surface of the drill pipe 21. The surface of the drill pipe 21 is sealed and connected to the sleeve shaft 17. A drill bit 34 is fixedly installed at the bottom of the drill pipe 21. A guide mechanism is provided at the bottom end of the drill pipe 21. The guide mechanism includes a guide plate 22, which is rotatably connected to the inside of the drill pipe 21. The guide plate 22 is correspondingly arranged on one side of the limiting mechanism. The inside of the drill pipe 21 is fixedly connected to the support 29 through a support rod. The bottom of the support 29 is connected to the piston 31 through a second spring 30, and the piston 31 is sealed and sleeved with the inside of the drill pipe 21. The inner wall of the drill pipe 21 is fixedly connected with a rib 40, and the rib 40 is fitted and slidably engaged with the inner edge of the piston 31.

[0038] In the present technical solution, the water source entering the drill pipe 21 first passes through the guide plate 22, and the impact force of the water flow is used to drive the guide plate 22 to rotate, so that the guide plate 22 pushes the translation plate 24 to translate to both sides, so that the translation plate 24 is against the inner wall of the hole. When the water source fills the inside of the drill pipe 21, it pushes the piston 31 to move downward. At this time, the water pressure overcomes the elasticity of the second spring 30 to move the piston 31 downward.

[0039] The bottom of the drill pipe 21 is connected to the inside of the shell 26 through an overflow pipe 39. The drill pipe 21 is provided with an opening for discharging water, and the overflow pipe 39 is correspondingly arranged above the opening. The shell 26 is an annular structure and is provided with a rubber ring 27 inside. The bottom of the rubber ring 27 is sealed and slid with the inside of the shell 26, and a vertically distributed gap is provided at the top of the rubber ring 27. A guide ring 28 is movably sleeved on the surface of the shell 26, and the guide ring 28 is engaged with the top of the shell 26. A limiting mechanism is fixedly installed at the bottom of the shell 26, and the limiting mechanism includes a baffle 23. The baffle 23 and the inside of the drill pipe 21 are both inserted through the translation plate 24. The translation plate 24 is correspondingly arranged on one side of the guide plate 22. One end of the translation plate 24 is connected to the inner wall of the drill pipe 21 through a first spring 25, and the other end of the translation plate 24 is an arc structure.

[0040] In the present technical solution, when the piston 31 moves downward, the overflow pipe 39 is located above the piston 31. At this time, the water source enters the shell 26 from the overflow pipe 39, and the water pressure pushes the rubber ring 27 to move upward, so that the rubber ring 27 lifts the guide ring 28, and the guide ring 28 is limited by the baffle 23. At this time, the deformation of the rubber ring 27 when it moves on the surface of the guide ring 28 causes it to bend on both sides, thereby blocking the gap between the translation plate 24 and the baffle 23. At this time, the water pressure continues to push the piston 31 downward.

[0041] A protection mechanism is fixedly installed at the bottom of the drill pipe 21, and the protection mechanism includes a limit plate 35 and a sleeve 36. The limit plate 35 is fixedly connected to the top of the drill bit 34, the limit plate 35 is located inside the drill pipe 21, and the limit plate 35 is rotatably connected to the sleeve 36. A guide block 38 is fixedly connected to the inner wall of the top end of the sleeve 36, and a guide column 32 is movably sleeved inside the sleeve 36. The guide column 32 is fixedly connected to the bottom of the piston 31, and an arc groove 33 is opened on the surface of the guide column 32, and the guide block 38 is slidably connected to the inside of the arc groove 33. The outer wall of the sleeve 36 is fixedly connected to the arc plate 37 through a connecting plate, and the arc plate 37 is sealed and fitted with the surface of the drill pipe 21, and the connecting plate is located inside the opening opened in the drill pipe 21.

[0042] In the present technical solution, when the piston 31 moves, it drives the guide column 32 to move synchronously. The sleeve 36 is rotated by the cooperation of the arc groove 33 and the guide block 38. The sleeve 36 drives the arc plate 37 to rotate and then open the opening. At this time, the piston 31 moves to the opening, so that water is poured into the drilled hole. Since the top of the hole is blocked, the water pressure formed penetrates around the hole with the hole as the center, so as to realize the irrigation of the deep soil layer of the saline-alkali land to prevent water evaporation. During the drilling process, the arc plate 37 protects the opening, and the sleeve 36 cannot drive the guide column 32 to rotate, which plays a self-locking function. The water pressure can be used to drive the sleeve 36 to rotate by the downward movement of the guide column 32, thereby realizing the opening of the arc plate 37, avoiding the problem of soil blocking the opening during the drilling process. After the hole is in place, irrigation can be achieved while delivering water.
