Description

Technical Field

[0001] This utility model relates to the technical field of salt removal equipment, and in particular to a salt removal equipment for improving saline-alkali land soil. Background Technology

[0002] Saline-alkali soil refers to soil with excessively high salt and alkali content, leading to soil deterioration, decreased fertility, and impaired plant growth. Salt removal equipment for saline-alkali soil improvement is used to reduce the salt content in saline-alkali soil. Through physical, hydraulic, and mechanical means, it removes and dilutes excess salt in the soil, reduces soil salinity, improves soil physicochemical properties, and promotes plant growth.

[0003] A search revealed Chinese Patent Publication No. CN221829417U, which discloses a salt removal device for improving saline-alkali land. The device includes a salt removal pipe with a secondary pipe at its left end and a water inlet pipe connected to the top right side of each pipe. A motor is fixedly installed in the middle left side of the secondary pipe's inner cavity. The motor's rotor is coaxially connected to a rotating shaft. Heating rods are circumferentially connected to the right side of a connecting ring. Spiral rods are fixedly connected to both sides of the right side of the rotating shaft. This salt removal device for improving saline-alkali land uses a motor to drive the rotating shaft, which in turn drives a second gear via a connecting plate. This, in turn, drives the connecting ring via a first gear, which in turn drives the heating rods and spiral rods. This allows the spiral rods and heating rods to effectively heat the water in the salt removal pipe, quickly removing the salt layer from the soil surface and preventing salt caking in cold weather. However, existing pipe systems can only be used on relatively uniform ground surfaces and cannot be adjusted to suit different ground conditions. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a salt removal device for improving saline-alkali land soil, which aims to improve the existing pipeline devices in the prior art, which can only be used on ground with relatively uniform height and cannot be adjusted according to the specific conditions of the ground.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a salt removal device for saline-alkali land soil improvement, comprising multiple salt removal pipes, lifting mechanisms installed on the left and right sides of the outer wall of each salt removal pipe for raising the height of the salt removal pipe, a blowing mechanism installed on the upper front side of the outer wall of each salt removal pipe for blowing sprayed water mist, a heating mechanism installed inside the salt removal pipe for heating the water inside the salt removal pipe, a recovery mechanism installed on the upper front side of the outer wall of each salt removal pipe for recovering melted brine, and multiple moving mechanisms equidistantly installed on the left and right sides of the outer wall of each salt removal pipe for moving the salt removal pipe; the lifting mechanism includes a connecting plate installed on the left and right sides of the outer wall of the salt removal pipe, and an inner slider guide plate installed on the outer wall of the connecting plate on the side furthest from each other; a driving assembly is installed on the top of the salt removal pipe.

[0006] The above technical solution involves fixing the inner slider guide plate to the left and right sides of the outer wall of the salt discharge pipe, providing installation support for the entire lifting mechanism. The inner slider guide plate is installed on the outside of the connecting plate, and its main function is to restrict the movement direction of the connecting plate. Through its sliding guide function, it ensures that the connecting plate rises and falls smoothly in the vertical direction, preventing swaying or deviation.

[0007] As a further description of the above technical solution:

[0008] The drive assembly includes a motor, which is mounted on top of the salt discharge pipe. A fixed long rod is fixedly connected to the output end of the motor. Multiple bevel gears are fixedly connected at equal intervals to the outer wall of the fixed long rod. The bottom of each bevel gear is meshed with a bevel gear. A threaded rod is fixedly connected to the bottom end of the bevel gear. A tee pipe is installed on top of the salt discharge pipe. The outer wall of the threaded rod is threadedly connected to the inside of a connecting plate. A support plate is fixedly connected to the bottom of the motor.

[0009] The above technical solution involves a motor (Motor 1) serving as the power source, installed at the top of the salt discharge pipe. Upon startup, its output drives a fixed long rod to rotate. Multiple bevel gears (Motor 2) on the fixed long rod rotate synchronously with it. Since bevel gears 2 mesh with bevel gear 1, the rotation of bevel gear 2 is transmitted to bevel gear 1, causing the threaded rod fixedly connected to the bottom of bevel gear 1 to rotate along with it. The threaded rod is threadedly connected to the inside of the connecting plate. Therefore, when the threaded rod rotates, the connecting plate moves up and down along the axial direction of the threaded rod, achieving the lifting and lowering adjustment of the salt discharge pipe.

[0010] As a further description of the above technical solution:

[0011] The blowing mechanism includes a fan blade, which is installed on the upper front side of the outer wall of the salt discharge pipe. A two-way pipe is provided at the bottom of the fan blade. Multiple nozzles are equidistantly connected to the bottom end of the two-way pipe. An actuation component is installed at the top of the two-way pipe.

[0012] The above technical solution works as follows: when the equipment is running, the actuator drives the fan blades to rotate, generating airflow. The wind accelerates the descent of moisture and loosens the salt layer, thereby improving the efficiency of saline-alkali land improvement.

[0013] As a further description of the above technical solution:

[0014] The execution component includes a second motor, which is installed on the upper front side of the outer wall of the salt discharge pipe. A worm gear is fixedly connected to the output end of the second motor. Multiple worm wheels are equidistantly meshed on the front side of the outer wall of the worm gear. A fixed rod is fixedly connected to the middle of the worm wheels. A support frame is installed on the top of the salt discharge pipe. The top end of the fixed rod is rotatably connected to the bottom front side of the support frame.

[0015] The above technical solution transmits the rotational motion of motor 2 to multiple worm wheels through the meshing of the worm and worm wheel, achieving the effect of synchronously driving the synchronous rotation of multiple components.

[0016] As a further description of the above technical solution:

[0017] The heating mechanism includes a heating tube installed inside the salt discharge pipe. A battery block is fixedly connected to the rear end of the outer wall of the heating tube, and a sealing plate is installed on the rear side of the outer wall of the heating tube.

[0018] The above technical solution utilizes the heating element's own heating characteristics to directly transfer heat to the soil or fluid inside the salt drainage pipe, thereby increasing the local temperature.

[0019] As a further description of the above technical solution:

[0020] The recycling mechanism includes a second water pump, which is installed on the front side of the middle part of the outer wall of the salt discharge pipe. The suction end of the second water pump is connected to an L-shaped three-way suction pipe, and the output end of the second water pump is connected to the front end of the outer wall of the salt discharge pipe.

[0021] Through the above technical solution: after the second water pump starts, it draws in saline wastewater or rinsing liquid from the external environment through the L-shaped three-way suction pipe. After the liquid is pressurized by the second water pump, it is transported to the inside of the salt discharge pipeline for storage through the output end.

[0022] As a further description of the above technical solution:

[0023] The moving mechanism includes a support rod, which is equidistantly installed on the left and right sides of the outer wall of the salt discharge pipe. A caster wheel is fixedly connected to the top of the support rod, and the top of the caster wheel is fixedly connected to the bottom of the elongated base plate.

[0024] The above technical solution allows the equipment to be moved easily across flat or slightly undulating ground when the salt drainage pipe is pushed, causing the casters to roll on the ground. The support rods move synchronously with the casters, improving operational flexibility.

[0025] As a further description of the above technical solution:

[0026] A water storage tank is fixedly connected to the middle of an adjacent side of the outer wall of the support frame. A water pump is fixedly connected to the front side of the outer wall of the water storage tank. The suction end of the water pump is connected to the water storage tank. The output end of the water pump is connected to the three-way pipe. Multiple barbed rings are fixedly connected at equal intervals to the outer wall of the salt discharge pipe. A support square plate is fixedly connected to the left side of the outer wall of the support frame.

[0027] Through the above technical solution: after the water pump starts, it draws liquid from the water storage tank, pressurizes the liquid through the output end and delivers it to the second tee pipe, and then sprays it out through the nozzle to soften the salt layer. Multiple barbed rings are fixed at equal intervals on the outer wall of the salt discharge pipe. During the process of the pipe being inserted into the soil or moving, the barbed rings can break up the hardened saline-alkali soil layer, increase the soil porosity, and the sharp structure of the barbed rings creates more permeability channels around the salt discharge pipe, which facilitates the collection of leachate or salt solution into the pipe and improves the salt discharge efficiency.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, after the motor is started, it drives the output end and the long rod to rotate synchronously and mesh with the second bevel gear on the outer wall. The second bevel gear meshes with the first bevel gear below, so that the threaded rod and the connecting plate move synchronously. The inner slider guide plate provides guidance for the lifting process, ensuring that the salt discharge pipe moves smoothly and the height of the salt discharge pipe can be adjusted to adapt to different terrains or soil salinity depths, thus optimizing the salt discharge efficiency. This avoids the problem that existing pipe devices can only be used on ground with relatively uniform heights and cannot be adjusted according to the conditions of the ground.

[0030] 2. In this utility model, after the motor starts, the worm drives multiple worm wheels to rotate synchronously. The worm wheels are connected to the fixed rod, which makes the fan blades rotate at high speed to generate airflow. At the same time, the water pump draws water from the water storage tank and sprays it onto the ground through the nozzle to dissolve the salt crust and form a low-salt solution. The airflow generated by the fan blades helps to accelerate the infiltration of water and reduce evaporation, thereby improving the working efficiency of the equipment. Attached Figure Description

After the sucked liquid is pressurized by the second water pump 601, it is transported to the inside of the salt discharge pipe 1 for storage through the output end.

[0043] Specifically, after the motor 3041 is started, its output end drives the worm 3047 to rotate. Multiple worm wheels 3046 on the outer wall of the worm 3047 rotate synchronously due to their meshing relationship. The fixed rod 3045 in the middle of the worm wheel 3046 rotates with the worm wheel 3046.

Multiple barbed rings 5 ​​are fixedly connected at equal intervals on the outer wall of the salt discharge pipe 1. A support square plate 3042 is fixedly connected to the left side of the outer wall of the support frame 3048.

Then it is sprayed out through nozzle 302 to soften the salt layer. Multiple barbed rings 5 ​​are fixed at equal intervals on the outer wall of the salt discharge pipe 1. During the process of the pipe being inserted into the soil or moving, the barbed rings 5 ​​can break the hardened saline-alkali soil layer and increase the soil porosity. The sharp structure of the barbed rings 5 ​​makes more permeable channels form around the salt discharge pipe 1, which facilitates the collection of leachate or salt solution into the pipe and improves the salt discharge efficiency.

[0046] Working principle: After the motor 2031 is started, it drives the output end to drive the fixed long rod 2033 and the multiple bevel gears 2034 on the outer wall to rotate synchronously. The rotating bevel gears 2034 mesh with the bevel gear 2032 below. The threaded rod 2038 fixed at the bottom of the bevel gear 2032 rotates synchronously with the bevel gear 2032. The connecting plate 201 on the outer wall of the threaded rod 2038 moves on the outer wall of the threaded rod 2038. The inner slider guide plate 202 on the outer wall of the connecting plate 201 provides guidance for the lifting process, ensuring that the salt discharge pipe 1 moves smoothly and avoids tilting or deviation. By adjusting the height of the salt discharge pipe 1, it can adapt to different terrains or soil salinity distribution depths, optimize salt discharge efficiency, and thus avoid the problem that existing pipe devices can only be used on ground with relatively uniform height and cannot be adjusted according to the ground conditions.

[0047] After the motor 3041 is started, the output end drives the worm 3047 to rotate. Multiple worm wheels 3046 on the outer wall of the worm 3047 rotate synchronously due to their meshing relationship. The fixed rod 3045 in the middle of the worm wheel 3046 rotates with the worm wheel 3046. The bottom end of the fixed rod 3045 is connected to the fan blade 301, thereby driving the fan blade 301 to rotate at high speed and generate airflow downward. Then, after the water pump 3044 starts, it draws liquid from the water storage tank 3043 and delivers it to the nozzle 302 at the bottom of the three-way pipe 303 to spray onto the ground salt layer, dissolving the surface salt crust and forming a low-salt solution. The airflow generated downward by the fan blade 301 can accelerate the infiltration of water and reduce water evaporation, thereby improving the working efficiency of the equipment.
