Description

Technical Field

[0001] The utility model relates to the field of equipment for arable land soil remediation, in particular to an agricultural soil remediation and plowing integrated machine. Background Technique

[0002] The arable land soil spraying remediation technology is an in-situ remediation technology. It sprays specific leaching solutions onto the soil surface to promote 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 suitable for treating heavy metals and organic pollutants, especially more 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 from injection wells into the soil pollution area, carrying the pollutants to the groundwater and then pumping out the contaminated groundwater with a pump, and removing the pollutants on the ground. The ex-situ chemical leaching technology requires excavating the contaminated soil, washing the soil with the leaching agent solution to remove the pollutants, and then treating the washing wastewater or liquid waste containing the pollutants. The clean soil can be backfilled or transported to other places 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 the prior art needs to carry out multiple remediations at long intervals when remediating agricultural soil, and provides an agricultural soil remediation and plowing integrated machine. By using the integrated method of plowing and path spraying, high-efficiency soil remediation is achieved through plowing and agent mixing at short intervals, so that agricultural soil can be remediated and restored to production faster.

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

[0007] An agricultural soil remediation and plowing integrated machine, including a vehicle body, an engine is installed on the vehicle body, a power chassis capable of driving the vehicle body to move is provided on the vehicle body. It is characterized in that a medicine water tank is provided on the vehicle body, a plowing mechanism is provided on one side of the vehicle body, a hinge arm is provided between the plowing mechanism and the vehicle body, one end of the hinge arm is hinged to the vehicle body, and the other end thereof is hinged to the plowing mechanism;

[0008] A path spraying mechanism is provided on the side of the plowing mechanism close to the vehicle body, and the path spraying mechanism is communicated with the medicine water tank.

[0009] Currently, when in-situ remediation of agricultural soil is carried out, large-scale spraying and irrigation of liquid medicine is usually adopted, followed by ploughing for remediation. However, due to the damage to the soil itself, it is prone to hardening. Therefore, when the sprayed liquid medicine is not ploughed, it is not easy to penetrate. But if ploughing is done first and then spraying, it is also difficult to effectively mix with the soil, thus reducing the soil remediation efficiency. On this basis, if equipment with separate spraying and ploughing is used, separate operations are required, and in this case, there will be a relatively long interval between spraying and ploughing, resulting in uneven action of the liquid medicine in the soil. Therefore, more remediation liquid is needed to achieve the same soil remediation effect, reducing the soil remediation efficiency and increasing the soil remediation cost.

[0010] The utility model effectively reduces the interval time between spraying remediation and ploughing through the combined action of the vehicle body and the ploughing mechanism on the vehicle body travel route, thereby improving the soil remediation efficiency. Through the path spraying mechanism, it can effectively cooperate with the ploughing mechanism to efficiently remediate the corresponding area on the vehicle body travel route. The articulated arm effectively adapts to the undulation of the terrain of agricultural fields in the form of double-headed articulation, thus preventing the ploughing mechanism from getting stuck during travel.

[0011] The medicine water tank in the utility model is used to hold the remediation medicine water for soil remediation. The path spraying mechanism can draw out the medicine water from the medicine water tank to improve the soil properties on the travel path. The power chassis is used to provide the mobility for the overall machinery, thereby ensuring that the vehicle body can complete the mixing of the soil and the remediation medicine water while maintaining the ploughing of the ploughing mechanism.

[0012] Furthermore, an outspread spraying mechanism is also provided on the vehicle body. The outspread spraying mechanism can pump out the liquid in the medicine water tank and spray it on both sides outside the vehicle body.

[0013] In the utility model, the outspread spraying mechanism increases the spraying area, thereby realizing multiple sprays on the soil in a shorter time and achieving a better soil remediation effect.

[0014] Furthermore, the power chassis includes a Christie fully independent suspension. Around the Christie fully independent suspension, there are several rocker tensioning follower wheel systems. Tensioning rockers are provided between the rocker tensioning follower wheel systems and the Christie fully independent suspension. One end of the tensioning rocker is articulated with the rocker tensioning follower wheel system, and the other end is articulated with the Christie fully independent suspension;

[0015] A driving wheel is provided on one side of the Christie fully independent suspension. A crawler is provided on the driving wheel and the rocker tensioning follower wheel system, and the driving wheel and the rocker tensioning follower wheel system tension the crawler;

[0016] A damping shock absorption system is provided between the tension rocker arm and the Christie fully independent suspension.

[0017] In the present utility model, drive wheels are driven by DC motors on both sides inside the vehicle body to drive the crawler to rotate, and the remaining wheels are driven wheels responsible for tensioning the crawler to support the vehicle body. In cooperation with the Christie fully independent suspension and the oil pressure damping shock absorption structure, the vehicle body moves stably.

[0018] Further, the plowing mechanism includes a tractor, and the tractor is hinged to the articulated arm;

[0019] A storage battery is provided on the tractor. A plowing frame body is provided on one side of the tractor. A plowing harrow is carried on the plowing frame body. A mudguard is provided between the plowing harrow and the plowing frame body.

[0020] In the present utility model, the storage battery can effectively supply energy to the tractor. The plowing harrow is carried by the plowing frame body, and the plowing of the soil is realized by the rotation of the plowing harrow. The mudguard can effectively prevent mud and water from splashing onto the storage battery.

[0021] Further, the plowing harrow includes a rotating shaft, the rotating shaft is rotatably connected to the plowing frame body, and a plurality of harrow bodies are provided on the rotating shaft, and the harrow bodies are circumferentially and evenly distributed on the outer surface of the rotating shaft.

[0022] In the present utility model, the rotation of the rotating shaft in the plowing harrow can drive the harrow body to dig into the soil, and under the energy supply of the storage battery, a damping can be applied to the rotating shaft through devices such as a motor, so that the harrow body can be inserted deeper into the ground, achieving a better plowing effect.

[0023] Further, the harrow body includes a bearing frame body, one side of the bearing frame body is fixed to the rotating shaft, and the other end thereof is provided with a harrow end housing, and the harrow end housing is hinged to the bearing frame body.

[0024] In the present utility model, the bearing frame body in the harrow body is used to bear the force of the harrow body for plowing the soil, and the harrow end housing can effectively plow the soil. Since the harrow end housing is hinged to the bearing frame body, there is a movable space between the harrow end housing and the bearing frame body, so that the harrow end housing does not plow the soil at a fixed angle, and can insert into the soil and plow at a more effective angle, so as to better adapt to the terrain changes of agricultural fields.

[0025] Further, a central column is provided at the center of the bearing frame body. The central column is perpendicular to the rake end housing. The interior of the central column communicates with the rake end housing. A central sphere is provided at the connection between the central column and the rake end housing. A plurality of tension springs are provided on the central sphere. One end of each tension spring is fixed to the rake end housing, and the other end is fixed to the central sphere. A compression spring is provided inside the central column. One end of the compression spring is fixed to the central column, and the other end is fixed to the central sphere.

[0026] In the present utility model, the bearing frame body is used to bear the overall force of the rake body. Since the center position of the frame structure is prone to deformation, the present utility model uses a central column to strengthen the center position of the bearing frame body. The central sphere can effectively strengthen the connection stability between the rake end housing and the central column in a filling form, so that the hinge connection stability between the rake end housing and the bearing frame body can be strengthened, effectively avoiding local damage at the position where the central sphere is located. Through the combined action of the tension springs and the compression spring, the central sphere is buffered in all directions, thereby avoiding the central sphere from pressing on the connection position and making the state of the connection position more stable.

[0027] Further, an elastic filling is provided inside the rake end housing, and the elastic filling fills the internal space of the rake end housing.

[0028] In the present utility model, the rake end housing effectively enhances the anti-deformation ability of the housing through the elastic filling, so as to better plow the soil.

[0029] Further, a support medicine spreading shaft is also provided inside the bearing frame body. The support medicine spreading shaft is filled with medicine particles. A plurality of medicine outlets are provided on the support medicine spreading shaft, and the medicine particles can be scattered from the medicine outlets.

[0030] In the present utility model, the support medicine spreading shaft uses the plowing process of the rake body to put solid medicine particles into the soil, thereby further enhancing the ability to improve the soil properties.

[0031] Further, the support medicine spreading shaft includes a shaft body. The shaft body is fixed to the bearing frame body. A plurality of layered plates are provided inside the shaft body. The layered plates can divide the inside of the shaft body along the axial direction into a plurality of independent spaces. A driving rod penetrating the shaft body along the axial direction is provided inside the shaft body. The driving rod can rotate around the axis. A stirring plate is provided in each independent space, and each stirring plate is connected to the driving rod;

[0032] The medicine outlets are opened on the side surface of the shaft body. The medicine outlets are distributed along the axial direction of the shaft body, and each independent space is provided with a medicine outlet.

[0033] In the present utility model, the shaft body is used to accommodate the medicament particles, the layered plate is used to separate the internal space of the shaft body, the driving rod is used to drive the stirring plate to rotate so as to discharge the medicament particles from the medicine outlet, and when the medicament particles are discharged from the medicine outlet, by the action of centrifugal force, they can be effectively mixed into the soil.

[0034] To sum up, compared with the prior art, the present utility model has the following beneficial effects:

[0035] (1) Through the combined action of the vehicle body and the plowing mechanism on the traveling route of the vehicle body, the present utility model effectively reduces the interval time between spraying repair and plowing, thereby improving the soil repair efficiency. Through the path spraying mechanism, it can effectively cooperate with the plowing mechanism to efficiently repair the corresponding area on the traveling route of the vehicle body. The articulated arm, in the form of a double-headed hinge, effectively adapts to the undulations of the agricultural field terrain, thereby preventing the plowing mechanism from getting stuck during travel.

[0036] (2) The bearing frame in the harrow body is used to bear the force of the harrow body for plowing the soil, and the harrow end housing can effectively plow the soil. Since the harrow end housing is hinged to the bearing frame, there is a movable space between the harrow end housing and the bearing frame, so that the harrow end housing does not plow the soil at a fixed angle, but can insert into the soil at a more effective angle and plow, thus being able to better adapt to the terrain changes of the agricultural field.

[0037] (3) The shaft body is used to accommodate the medicament particles, the layered plate is used to separate the internal space of the shaft body, the driving rod is used to drive the stirring plate to rotate so as to discharge the medicament particles from the medicine outlet, and when the medicament particles are discharged from the medicine outlet, by the action of centrifugal force, they can be effectively mixed into the soil.

The illustrative embodiments and descriptions thereof of the present utility model are only used to explain the present utility model and shall not be construed as a limitation to the present utility model.

[0045] Embodiment:

[0046] As Figures 1 to 4 shown, this embodiment relates to an agricultural soil remediation and ploughing integrated 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 provided on the vehicle body 3, a medicine water tank 2 is provided on the vehicle body 3, a ploughing mechanism is provided on one side of the vehicle body 3, and an articulated arm 12 is provided between the ploughing mechanism and the vehicle body 3. One end of the articulated arm 12 is hinged to the vehicle body 3, and the other end thereof is hinged to the ploughing mechanism;

[0047] A path spraying mechanism 13 is provided on the side of the ploughing mechanism close to the vehicle body 3, and the path spraying mechanism 13 is communicated with the medicine water tank 2.

[0048] An outspread spraying mechanism 11 is further provided on the vehicle body, and the outspread spraying mechanism 11 can pump the liquid in the medicine water tank and spray it on both sides outside the vehicle body 3.

[0049] In practical applications 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 movement of the vehicle body 3, the outstretched spraying mechanism 11 will pump out the liquid in the medicine water tank 2 and spray it onto 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. And the path spraying mechanism 13 in this embodiment can effectively spray the blind area of the outstretched spraying mechanism 11 on the traveling path, so as to ensure that the positions plowed by the plowing mechanism are all sprayed with the remediation liquid, achieving the purpose of effectively improving the soil properties.

[0050] 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 outstretched 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.

[0051] The power chassis 4 includes a Christie fully independent suspension 43. A number of rocker tensioning idler systems 41 are arranged around the Christie fully independent suspension 43. Tensioning rockers 42 are arranged between the rocker tensioning idler systems 41 and the Christie fully independent suspension 43. One end of the tensioning rocker 42 is hinged to the rocker tensioning idler system 41, and the other end is hinged to the Christie fully independent suspension 43;

[0052] A driving wheel 47 is arranged on one side of the Christie fully independent suspension 43. A crawler 46 is arranged on the driving wheel 47 and the rocker tensioning idler system 41. The driving wheel 47 and the rocker tensioning idler system 41 tension the crawler 46;

[0053] Damping shock absorption systems 45 are arranged between the tensioning rockers 42 and the Christie fully independent suspension 43.

[0054] The driving wheel 47 is driven by the DC motors on both sides inside the vehicle body to drive the crawler 46 to rotate. The other wheels are idlers responsible for tensioning the crawler and supporting the vehicle body 3, and cooperate with the Christie fully independent suspension 43 and the oil pressure damping shock absorption structure to make the vehicle body move stably. The damping shock absorption system 45 of this embodiment adopts oil pressure damping shock absorption.

[0055] The plowing mechanism includes a tractor 8, and the tractor 8 is hinged to the articulated arm 12;

[0056] A storage battery 9 is provided on the tractor 8. A plough frame body 5 is provided on one side of the tractor 8. A plough harrow 6 is carried on the plough frame body 5. A mudguard 7 is provided between the plough harrow 6 and the plough frame body 5.

[0057] The plough harrow 6 includes a rotating shaft 61. The rotating shaft 61 is rotatably connected to the plough frame body 5. A plurality of harrow bodies 62 are provided on the rotating shaft 61. The harrow bodies 62 are circumferentially and evenly distributed on the outer surface of the rotating shaft 61.

[0058] 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. Under the power supply of the storage battery 9, damping can be applied to the rotating shaft 61 through devices 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.

[0059] The harrow body 62 includes a bearing frame body 625. One side of the bearing frame body 625 is fixed to the rotating shaft, and the other end is provided with a harrow end housing 622. The harrow end housing 622 is hinged to the bearing frame body 625.

[0060] A central column 626 is provided at the center of the bearing frame body 625. The central column 626 is perpendicular to the harrow end housing 622. The inside of the central column 626 is communicated with the harrow end housing 622. A central sphere 624 is provided at the communication place between the central column 626 and the harrow end housing 622. A plurality of tension springs 623 are provided on the central sphere 624. One end of the tension spring 623 is fixed to the harrow end housing 622, and the other end is fixed to the central sphere 624. A compression spring 627 is provided in the central column 626. One end of the compression spring 627 is fixed to the central column 626, and the other end is fixed to the central sphere 624.

[0061] An elastic filling 621 is provided in the harrow end housing 622. The elastic filling 621 fills the internal space of the harrow end housing 622.

[0062] In this embodiment, the bearing frame body 625 axially flips under the action of the rotating shaft 61. The harrow end housing 622 can effectively insert into the soil and plough the soil. The path spraying mechanism 13 has sprayed the repair liquid medicine on the soil, so the harrow end housing 622 can effectively turn the soil out of the ground and promote the mixing of the soil and the repair liquid medicine. The harrow end housing 622 is hinged to the bearing frame body 625, so that the harrow end housing 622 can adapt to more angles of inserting into the soil, thereby avoiding the situation that the harrow body 62 is stuck due to the undulation of the terrain in the field.

[0063] When the rake end shell 622 is acted upon by an external force, the force is transferred to the inside. The elastic filling 621 in the rake end shell 622 can effectively provide elastic support, thereby preventing the rake end shell 622 from deforming and enhancing the anti-deformation ability of the rake end shell 622.

[0064] The central sphere 624 is located at the connection between the central column 626 and the rake end shell 622. Since the central column 626 needs to provide effective support for the supporting frame 625, and the hinged connection between the rake end shell 622 and the supporting frame 625 causes a gap space between the central column 626 and the rake end shell 622. During the plowing process, the gap space is easily blocked, causing the rake end shell 622 to lose flexibility. In addition, the connection position between the rake end shell 622 and the central column 626 is also prone to collision, resulting in weakened support and mobility.

[0065] In this embodiment, the center column 626 and the rake end shell 622 are connected, and a center sphere 624 is set at the connection point for sealing. Since the center sphere 624 can rotate flexibly and provide support, the center sphere 624 is used to fill the connection point between the center column 626 and the rake end shell 622. This can not only ensure the flexibility of the connection between the center column 626 and the rake end shell 622, but also use the center sphere 624 to improve the resistance of the rake end shell 622 when it is subjected to force, so that the rake end shell 622 can obtain stronger stability during the plowing process.

[0066] A medicine-spreading support shaft 628 is further provided in the supporting frame 625 . The medicine-spreading support shaft 628 is filled with medicine particles 6282 . A plurality of medicine outlets 6283 are provided on the medicine-spreading support shaft 628 . The medicine particles 6282 can be sprinkled from the medicine outlets 6283 .

[0067] In this embodiment, the supporting medicine spreading shaft 628 is used to not only partially reinforce the supporting frame 625 and enhance its anti-deformation ability, but also to spread the medicine particles 6282 through the medicine outlet 6283 to help repair the soil.

[0068] The supporting medicine spreading shaft 628 includes a shaft body 6281, which is fixed to the supporting frame 625. A plurality of layered plates 6285 are provided in the shaft body 6281. The layered plates 6285 can divide the shaft body 6281 into a plurality of independent spaces along the axial direction. A driving rod 6286 is provided in the shaft body 6281 along the axial direction and passes through the shaft body 6281. The driving rod 6286 can rotate around the axis. A stirring plate 6284 is provided in each of the independent spaces, and the stirring plates 6284 are connected to the driving rod 6286.

[0069] The medicine outlet 6283 is opened on the side surface of the shaft body 6281. The medicine outlet 6283 is distributed along the axial direction of the shaft body 6281, and each of the independent spaces is provided with a medicine outlet 6283.

[0070] In this embodiment, the shaft body 6281 can enhance the anti-deformation ability of the bearing frame 625. The layered plate 6285 can effectively divide the interior of the shaft body 6281 into multiple layers of spaces, so that each space can independently scatter the medicament particles 6282, effectively enhancing the uniformity of the scattering of the medicament particles 6282. The driving rod 6286 can be driven by a motor. The medicament particles 6282 are agitated by the agitation plate 6284 and scattered from the medicine outlet 6283 by centrifugal action, so as to achieve the purpose of assisting in soil repair.

[0071] The specific embodiments described above have further elaborated 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.
