Description

Technical Field

[0001] The utility model relates to the field of equipment for arable land soil remediation, and particularly to an agricultural soil remediation spraying and plowing machine. Background Art

[0002] The spraying remediation technology for arable land soil is an in-situ remediation technology. By spraying specific leaching solutions onto the soil surface, it promotes the transfer of pollutants from the soil solid-phase particles to the liquid phase, achieving the purpose of soil purification and reduction of contaminated soil. This technology is applicable to the treatment of heavy metals and organic pollutants, and is particularly effective for the remediation of large-particle-size contaminated soil. The spraying remediation technology can be carried out in-situ or ex-situ, depending on the specific conditions of the contaminated soil and the remediation objectives.

[0003] In-situ soil leaching technology generally refers to the process of injecting or infiltrating the flushing solution into the soil pollution area through injection wells, carrying the contaminants to the groundwater, and then pumping out the contaminated groundwater with a pump and removing the contaminants on the ground. Ex-situ chemical leaching technology, on the other hand, requires excavating the contaminated soil, washing the soil with the leaching agent solution to remove the contaminants, and then treating the washing wastewater or waste liquid containing the contaminants. The clean soil can be backfilled or transported to other locations for reuse.

[0004] Due to the large scale of arable land soil, in order to control costs, in-situ remediation is generally adopted. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiency that when in-situ remediation of arable land soil is adopted in the prior art, due to factors such as soil compaction, plowing and chemical agent treatment need to be carried out separately, resulting in complex processes. The utility model provides an agricultural soil remediation spraying and plowing machine, which can effectively improve the soil remediation efficiency and the soil remediation effect by spraying the soil in an outspread manner and plowing synchronously.

[0006] The purpose of the utility model is mainly achieved through the following technical solutions:

[0007] An agricultural soil remediation spraying and plowing machine, including a vehicle body, an engine is installed on the vehicle body, and a power chassis capable of driving the vehicle body to move is also provided on the vehicle body. A medicine water tank is arranged on the top of the vehicle body, and the medicine water tank is connected with an outspread spraying mechanism. The outspread spraying mechanism can pump out the liquid in the medicine water tank and spray it on both sides outside the vehicle body;

[0008] A hinged arm is connected to the side of the vehicle body. One end of the hinged arm is hinged to the vehicle body, and the other end extends along the traveling direction of the vehicle body and is connected with a plowing mechanism. The hinged arm is hinged to the plowing mechanism.

[0009] Currently, farmland soil can become damaged over time due to farming activities. Damaged soil requires maintenance and repair, with external intervention needed to accelerate its recovery. Due to the damage caused by farming activities, the soil can become compacted and uneven, making it difficult to repair. Therefore, existing techniques typically involve plowing the plowed soil first, then spraying it, and then continuing with plowing. However, this extends the operation cycle and also affects the effectiveness of the operation due to the time gap between spraying and plowing.

[0010] The utility model connects the vehicle body and the plowing mechanism through an articulated arm, and carries a medicine liquid tank and an outward-extending spraying mechanism on the vehicle body. The power chassis is used to drive the vehicle body to move, and the vehicle body pulls the plowing mechanism to plow the cultivated soil, and at the same time, the medicine in the medicine liquid tank is sprayed on the cultivated soil through the outward-extending spraying mechanism. Although there is still a sequence time between spraying and plowing, the interval time is short, and the medicine liquid and the soil can be mixed by plowing. Not only can the soil be effectively prevented from being compacted and causing the medicine liquid to be obstructed from penetrating, but the plowing can also promote the mixing of the medicine liquid and the soil. Moreover, the interval time between plowing and spraying is short, which can make the soil and the medicine liquid mixed more evenly, avoid the problem of excessive concentration of the local medicine liquid caused by plowing after the medicine liquid is dry, and can also avoid the situation of inadequate local repair during the soil repair process to a certain extent.

[0011] Furthermore, the liquid medicine box includes a box body, the box body is provided with a liquid pumping main pipe, and the liquid pumping main pipe is connected to the outward-spreading spray mechanism;

[0012] A horizontal liquid pumping pipe is provided at the bottom end of the liquid pumping main pipe, the axis of the horizontal liquid pumping pipe is horizontal, a connecting end is provided between the liquid pumping main pipe and the horizontal liquid pumping pipe, and the liquid pumping main pipe and the horizontal liquid pumping pipe are fixedly connected via the connecting end;

[0013] The horizontal liquid extraction pipe is connected to a plurality of liquid extraction hoses, one end of each liquid extraction hose is connected to and communicates with the horizontal liquid extraction pipe, and the other end thereof extends to the bottom of the box body.

[0014] In the present invention, the box body is used to contain liquid, the horizontal liquid pumping pipe is used to expand the liquid pumping area, the liquid pumping hose is used to directly extract the liquid from the bottom of the box body, the liquid pumping main pipe is used to connect the outward-facing spray mechanism, and the connecting end is used to connect the horizontal liquid pumping pipe and the liquid pumping main pipe. The transfer connection through the connecting end can effectively control the liquid pumping flow rate, make the liquid pumping range larger, and make the extracted liquid easier to maintain uniformity.

[0015] Further, a medicament sphere is embedded in the connection end. The medicament sphere fills the internal space at the communication position between the horizontal liquid extraction pipe and the main liquid extraction pipe and can connect the horizontal liquid extraction pipe and the main liquid extraction pipe.

[0016] In the utility model, by adopting the method of embedding the medicament sphere into the connection end and putting the medicament into the medicament sphere, only the medicament needs to be put into the medicament sphere from the main liquid extraction pipe, and then through the way that the liquid flows through the medicament sphere, the liquid medicine configuration can be completed by using the liquid extraction action, avoiding putting the medicament into the medicine water tank. This can be beneficial to the protection of the medicine water tank, and can quickly change the type of medicament after the medicament is consumed, avoiding the excessive workload of thoroughly cleaning the medicine water tank.

[0017] Further, the medicament sphere includes a spherical shell. A top notch is provided at the top of the spherical shell. The top notch communicates with the main liquid extraction pipe. A plurality of through holes are provided on the side surface of the spherical shell. The through holes communicate with the horizontal liquid extraction pipe;

[0018] A net bag is provided in the top notch. An elastic band is provided in the upper half of the net bag. The elastic band circumferentially tightens the net bag.

[0019] In the utility model, the top of the spherical shell communicates with the main liquid extraction pipe, and the side of the spherical shell communicates with the horizontal liquid extraction pipe. Therefore, the liquid in the horizontal liquid extraction pipe converges at the connection end and is conveyed to the outspread spraying mechanism through the main liquid extraction pipe. The net bag provided at the top notch can receive the solid medicament put at the main liquid extraction pipe, hold the solid medicament by the net bag, and tighten the elastic band under the action of gravity. In this way, it is not easy to spray the solid medicament out of the main liquid extraction pipe under the action of the flowing liquid, but the liquid flowing into the outspread spraying mechanism all flows through the solid medicament. Therefore, the sprayed liquid all contains the components of the solid medicament, so as to achieve the purpose of repairing the soil by using the medicament liquid.

[0020] Further, an arc-shaped step is provided in the box body. The arc-shaped step circumferentially surrounds the bottom edge of the box body.

[0021] In the utility model, the arc-shaped step is used to set an arc transition at the bottom edge of the box body to avoid the precipitation of liquid at the edge gap.

[0022] Further, the power chassis includes a Christie fully independent suspension. A plurality of rocker arm tensioning driven wheel systems are provided around the Christie fully independent suspension. Tensioning rocker arms are provided between the rocker arm tensioning driven wheel systems and the Christie fully independent suspension. One end of the tensioning rocker arm is hinged to the rocker arm tensioning driven wheel system, and the other end thereof is hinged to the Christie fully independent suspension;

[0023] A driving wheel is provided on one side of the Christie fully independent suspension, and a crawler track is provided on the driving wheel and the rocker arm tensioning driven wheel system, and the driving wheel and the rocker arm tensioning driven wheel system tension the crawler track;

[0024] A damping and shock absorbing system is provided between the tensioning rocker arm and the Christie fully independent suspension.

[0025] In this utility model, the DC motors on both sides of the vehicle body drive the driving wheels to drive the crawler tracks to rotate, and the remaining wheels are driven wheels responsible for tightening the crawler tracks to support the vehicle body. Combined with the Christie fully independent suspension and hydraulic damping shock absorption structure, the vehicle body can move stably.

[0026] Furthermore, the plowing mechanism includes a tractor, and the tractor is hinged to the articulated arm;

[0027] A battery is provided on the tractor, a plow frame is provided on one side of the tractor, a plow harrow is mounted on the plow frame, and a mudguard is provided between the plow harrow and the plow frame.

[0028] In the present invention, the battery power supply can effectively power the tractor, and the plowing frame carries the plowing harrow, and the soil is plowed by the rotation of the plowing harrow. The mudguard can effectively prevent mud and water from splashing onto the battery.

[0029] Furthermore, the plow harrow includes a rotating shaft, which is rotatably connected to the plow frame. A plurality of harrow bodies are provided on the rotating shaft, and the harrow bodies are evenly distributed on the outer surface of the rotating shaft in a circumferential direction.

[0030] The utility model can drive the rake body to dig into the ground through the rotation of the rotating shaft in the plow harrow, and under the power supply of the battery, can apply damping to the rotating shaft through the motor and other equipment, so that the rake body can be inserted deeper into the ground, achieving a better plowing effect.

[0031] In summary, the present invention has the following beneficial effects compared with the prior art:

[0032] (1) The utility model connects the vehicle body and the plowing mechanism through an articulated arm, and carries a liquid medicine tank and an outward-extending spraying mechanism on the vehicle body. The power chassis is used to drive the vehicle body to move, and the vehicle body pulls the plowing mechanism to plow the cultivated soil, and at the same time, the liquid medicine in the liquid medicine tank is sprayed on the cultivated soil through the outward-extending spraying mechanism.

[0033] (2) In the present utility model, the top of the spherical shell is connected to the main liquid extraction pipe, and the side of the spherical shell is connected to the horizontal liquid extraction pipe. Therefore, the liquid in the horizontal liquid extraction pipe converges at the connection end and is transported to the outspread spraying mechanism through the main liquid extraction pipe. The net bag provided at the top notch can hold the solid medicament put at the main liquid extraction pipe, hold the solid medicament through the net bag, and tighten the elastic band under the action of gravity. In this way, it is not easy to spray the solid medicament out of the main liquid extraction pipe under the action of the flowing liquid.

Detailed Embodiments

[0042] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with embodiments and drawings. The illustrative embodiments of the present utility model and their descriptions are only used to explain the present utility model and do not limit the present utility model.

[0043] Embodiment:

[0044] As Figures 1 to 5 shown, this embodiment relates to an agricultural soil remediation spraying and plowing machine, including a vehicle body 3. An engine 1 is installed on the vehicle body 3. A power chassis 4 capable of driving the vehicle body 3 to move is also provided on the vehicle body 3. A medicine water tank 2 is provided at the top of the vehicle body 3. The medicine water tank 2 is connected to an outspread spraying mechanism 11. The outspread spraying mechanism 11 can pump out the liquid in the medicine water tank 2 and spray it on both sides outside the vehicle body 3.

[0045] A hinged arm 12 is connected to the side of the vehicle body 3. One end of the hinged arm 12 is hinged to the vehicle body 3, and the other end extends along the traveling direction of the vehicle body 3 and is connected to a plowing mechanism. The hinged arm 12 is hinged to the plowing mechanism.

[0046] In this embodiment, the medicine water tank 2, the engine 1, and the ends of the outspread spraying mechanism 11 are all surrounded by a guardrail 10 to avoid damage by impact.

[0047] In the actual application of this embodiment, the engine 1 drives the power chassis 4 to drive the vehicle body 3 to move. During the movement of the vehicle body 3, the plowing mechanism will be towed to plow the soil on the traveling path. During the traveling of the vehicle body 3, the outspread spraying mechanism 11 will pump out the liquid in the medicine water tank 2 and spray it on the soil on the traveling path. Therefore, this embodiment can realize the work of liquid spraying and plowing within a short intermittent time, plow the liquid and the soil more evenly when the liquid is not dry, make the contact between the soil and the liquid more sufficient, so as to achieve a better soil remediation effect, and can avoid the risk that the liquid cannot penetrate into the soil when sprayed on the compacted soil.

[0048] The plowing mechanism in the attached drawings of this embodiment can increase the lateral scale, so as to plow a larger area. The attached drawings are only schematic and do not limit the plowing range. The outspread spraying mechanism 11, the engine 1, and the vehicle body 3 all adopt models that can be configured on a large scale in the prior art.

[0049] The medicine water tank 2 includes a box body 21. A liquid pumping main pipe 22 is provided in the box body 21. The liquid pumping main pipe 22 is communicated with the outspread spraying mechanism 11. An arc-shaped step 26 is provided in the box body 21. The arc-shaped step 26 circumferentially surrounds the bottom edge of the box body 21.

[0050] The bottom end of the liquid extraction main pipe 22 is provided with a horizontal liquid extraction pipe 24. The axis of the horizontal liquid extraction pipe 24 is horizontal. A connection end 23 is provided between the liquid extraction main pipe 22 and the horizontal liquid extraction pipe 24. The liquid extraction main pipe 22 and the horizontal liquid extraction pipe 24 are fixedly connected through the connection end 23;

[0051] A number of liquid extraction hoses 25 are connected to the horizontal liquid extraction pipe 24. One end of the liquid extraction hose 25 is connected to and communicated with the horizontal liquid extraction pipe 24, and the other end extends to the bottom of the box body 21.

[0052] The connection end 23 is embedded with a medicine sphere 27. The medicine sphere 27 fills the internal space at the communicating position between the horizontal liquid extraction pipe 24 and the liquid extraction main pipe 22 and can communicate the horizontal liquid extraction pipe 24 and the liquid extraction main pipe 22.

[0053] In this embodiment, the box body 21 of the medicine water tank 2 stores liquid. The liquid is communicated with the outspread spraying mechanism 11 through the liquid extraction main pipe 22. The outspread spraying mechanism 11 can spray the liquid. The bottom end of the liquid extraction main pipe 22 horizontally expands the liquid extraction position through the horizontal liquid extraction pipe 24, and then is communicated with the bottom of the box body 21 through the liquid extraction hose 22. And due to the flexibility of the liquid extraction hose 25, it can effectively avoid the influence of vehicle body bumps on the liquid extraction main pipe 25 and the horizontal liquid extraction pipe 24. Since the liquid extraction main pipe 22 and the horizontal liquid extraction pipe 24 form a T-shaped channel, a medicine sphere 27 is arranged at the intersection position of the liquid extraction main pipe 22 and the horizontal liquid extraction pipe 24. The liquid sprayed by the outspread spraying mechanism 11 must flow through the medicine sphere 27. In this embodiment, the required soil remediation agent is put into the medicine sphere 27. The liquid sprayed by the outspread spraying mechanism 11 is the required remediation liquid. Using the medicine sphere 27 to hold the remediation agent can effectively avoid storing the liquid medicine in the box body 21. If the box body 21 is directly used to store the liquid medicine, when the liquid medicine needs to be replaced, the box body 21 needs to be thoroughly cleaned. In this embodiment, using the medicine sphere 27 can keep the inside of the box clean and can timely replace the remediation liquid by putting different remediation agents into the medicine sphere 27. In this embodiment, only by putting the remediation agent into the liquid extraction main pipe 22 can the remediation agent be put into the medicine sphere 27.

[0054] The medicine sphere 27 includes a spherical shell 274. The top of the spherical shell 274 is provided with a top notch 271. The top notch 271 is communicated with the liquid extraction main pipe 22. The side of the spherical shell 274 is provided with a number of through holes 275. The through holes 275 are communicated with the horizontal liquid extraction pipe 24;

[0055] A net bag 273 is arranged in the top notch 271. The upper half of the net bag 273 is provided with an elastic band 272. The elastic band 272 circumferentially tightens the net bag 273.

[0056] Since a large amount of fluid needs to flow through the liquid pumping main pipe 22, the repair agent in the agent sphere 27 is easily brought into the liquid pumping main pipe 22 and cannot be fully mixed. In this embodiment, after the repair agent is added to the liquid pumping main pipe 22, the repair agent falls into the net bag 273. Under the action of gravity, the net bag 273 falls, and the elastic band 272 is pulled to tighten. At this time, when the fluid flows through the net bag 273, it can be effectively mixed to form a repair liquid. However, since the elastic band 272 is tightened, the solid repair agent will not be rushed into the liquid pumping main pipe 22 with the fluid, but will be mixed and moved in the spherical shell 274, so that this embodiment can complete a relatively uniform mixing in the agent sphere 27 and stably form a soil repair liquid.

[0057] The power chassis 4 includes a Christie fully independent suspension 43, and a plurality of rocker arm tensioning driven gear trains 41 are arranged around the Christie fully independent suspension 43. A tensioning rocker arm 42 is provided between the rocker arm tensioning driven gear train 41 and the Christie fully independent suspension 43. One end of the tensioning rocker arm 42 is hinged to the rocker arm tensioning driven gear train 41, and the other end thereof is hinged to the Christie fully independent suspension 43.

[0058] A driving wheel 47 is provided on one side of the Christie fully independent suspension 43. A crawler belt 46 is provided on the driving wheel 47 and the rocker arm tensioning driven wheel system 41. The driving wheel 47 and the rocker arm tensioning driven wheel system 41 tension the crawler belt 46.

[0059] A damping and shock absorbing system 45 is provided between the tensioning rocker arm 42 and the Christie fully independent suspension 43 .

[0060] DC motors on either side of the vehicle body drive drive wheels 47, which in turn rotate tracks 46. The remaining wheels act as driven wheels, responsible for tensioning the tracks and supporting the vehicle body 3. This, combined with the Christie fully independent suspension 43 and hydraulic damping and shock absorption structure, ensures stable vehicle movement. The damping and shock absorption system 45 of this embodiment utilizes hydraulic damping and shock absorption.

[0061] The plowing mechanism includes a tractor 8, which is articulated with the articulated arm 12;

[0062] A battery 9 is provided on the tractor 8 , and a plow frame 5 is provided on one side of the tractor 8 . A plow harrow 6 is mounted on the plow frame 5 , and a fender 7 is provided between the plow harrow 6 and the plow frame 5 .

[0063] The plowing rake 6 includes a rotating shaft 61 , which is rotatably connected to the plowing frame 5 . A plurality of rake bodies 62 are provided on the rotating shaft 61 , and the rake bodies 62 are evenly distributed on the outer surface of the rotating shaft 61 in a circumferential direction.

[0064] In this embodiment, the rotation of the rotating shaft 61 in the plough harrow 6 can drive the harrow body 62 to dig into the soil. With the power supply of the storage battery 9, damping can be applied to the rotating shaft 61 through equipment such as motors, so that the harrow body 62 can be inserted deeper into the ground to achieve a better ploughing effect. When the span of the plough harrow 6 increases, the rotating shaft 61 can also be driven by a motor to form a propulsive force, thereby assisting the plough harrow 6 to move forward during the ploughing process and avoiding blocking the vehicle body 3.

[0065] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
