TECHNICAL FIELD

[0001] The application relates to the technical field of soil pollution treatment, in particular to a soil pollution treatment device. BACKGROUND

[0002] Due to rapid population growth and rapid industrial development, solid waste is continuously accumulated and dumped on the soil surface. Harmful wastewater continuously penetrates into the soil, in addition, harmful gases and particulate matters in the air also settle into the soil during the rainfall process, resulting in soil pollution. Any substance that hinders the normal function of the soil and reduces the yield and quality of crops and indirectly affects human health through food, vegetables and fruits is regarded as a soil pollutant.

[0003] The current soil pollution treatment device mainly relies on spraying soil repair liquid on the soil surface. Such repair liquid mainly acts on the surface layer of the soil, is easy to be lost due to evaporation, and is difficult to effectively penetrate into deeper soil. The effect of soil pollution treatment is not satisfactory. SUMMARY

[0008] By adopting the above technical scheme, through the synergistic effect of the cutting assembly and the soil turning assembly, the weeds on the surface of the soil are first cleaned and the soil is first loosened; next, the soil remediation liquid in the storage tank is transported into the external sleeve through the injection pipe by the negative pressure pump; in this process, the high pressure generated by the inflator causes the treatment agent to be released through the overflow hole; combined with the centrifugal rotation of the external sleeve, the treatment agent can be thrown into the loosened soil, which effectively sprays the agent into deeper soil, thereby ensuring the effect of soil pollution treatment; this method not only improves the penetration ability of the agent, but also helps to enhance the treatment efficiency of the agent on pollutants.

[0009] Preferably, the cutting assembly comprises a first transversely extending rod and a second transversely extending rod, the first transversely extending rod and the second transversely extending rod are fixedly connected through a first mounting rod and a second mounting rod, a back-shaped mounting area is formed between the first transversely extending rod, the second transversely extending rod, the first mounting rod and the second mounting rod, a bottom plate is fixedly installed in the mounting area, a driving motor is fixedly installed at the bottom of the bottom plate, and a cutting wheel is connected to the bottom output end of the driving motor.

[0010] By adopting the above technical scheme, the bottom plate provides reliable foundation support to ensure the stability of the cutting wheel; the driving motor is located on the bottom plate, and the bottom output end is directly connected to the cutting wheel, so that the rotary power generated by the driving motor is efficiently transmitted to the cutting wheel through this direct connection mode to start the cutting process; this design significantly improves the efficiency of power transmission and ensures the speed and intensity of the cutting action; driven by the driving motor, the cutting wheel can rotate rapidly to effectively cut the weeds on the surface of the soil and improve the efficiency of the treatment operation; compared with traditional manual or inefficient cutting methods, the use of this cutting assembly can significantly improve the working speed and efficiency.

[0011] Preferably, the cutting wheel is provided with at least two, and the rotation directions of the adjacent two cutting wheels in the horizontal plane are opposite.

[0012] By adopting the above technical scheme, since the rotation directions of the two cutting wheels are opposite, the forces generated during the cutting process can achieve a self-balancing state; this design effectively reduces the torsional moment generated by the equipment during operation, thereby reducing the stress concentration on the structure of the equipment; this self-balancing feature not only improves the operation stability of the equipment, but also prolongs its service life, ensuring the efficiency and safety of the cutting process.

[0016] By adopting the technical scheme, the tangential motion generated by the first land harrow during rotation acts on the soil, thereby forming a plowing force and achieving the effect of turning over the soil; the cutting and turning process of the first land harrow on the soil can quickly and uniformly loosen the soil, providing optimized soil conditions for subsequent soil remediation; this efficient soil treatment method not only improves the quality of turning over the soil, but also creates a more ideal environment for plant growth, thereby promoting the health and sustainable development of the soil.

[0018] By adopting the technical scheme, the mud guide plate is located obliquely above the first land roller, and a guide slope is designed on the inner surface thereof; the main function of the mud guide plate is to guide the loosened and collided soil during the soil turning process to move towards the ground; the vibration assembly is assembled between the vibration plate and the mud guide plate, which can cause the vibration plate to vibrate at high frequency, and the vibration is usually generated by an electric or pneumatic driving source, so that the vibration plate moves on the slope of the mud guide plate; during the rotation of the first land roller, the soil will collide with the guide slope of the mud guide plate; through the action of vibration, the vibration plate applies additional energy to the collided soil, thereby promoting the crushing of the soil; due to the influence of vibration, the crushed soil is effectively redirected and falls back to the ground, forming a more uniform soil surface; this process not only improves the looseness of the soil, but also optimizes the soil structure, providing a more ideal basis for subsequent agricultural activities.

[0019] Preferably, the guide slope of the guide board is provided with a second support side frame at the end position, the second support side frame is provided with a second rotating rod, the outer side of the second rotating rod is provided with a second land plane, and the outer surface of the second land plane is uniformly provided with a plurality of second land hooks.

[0020] Through the above technical scheme, the preliminary treatment of the first land plane and the vibration plate has realized the preliminary breaking and loosening of the soil; with the introduction of the second land plane, the tillage process is carried out in layers, thereby further improving the effect of soil tillage; this layered tillage method not only improves the soil structure and increases the air permeability and water retention capacity of the soil, but also effectively promotes the uniform distribution of nutrients, thereby providing a better soil environment for the growth of subsequent crops.

[0024] Through the above technical scheme, the soil remediation liquid overflowing in the overflow hole is introduced into the strip-shaped channel inside the protruding stripe through the connecting pipe, so that the medicine overflows along the direction of the protruding stripe, forming a horizontal spraying path; the outlet of the strip-shaped channel is arranged on the side surface of the protruding stripe, which not only effectively prevents the soil from blocking the overflow hole, but also ensures that the medicine is not vertically dropped during spraying, but is sprayed in a horizontal manner, thereby forming a spraying path that can cover a larger application area; this structure can accurately control the spraying direction of the soil remediation liquid, ensuring that the medicine is uniformly distributed in the application area, thereby improving the application effect; this design optimizes the application method of the medicine and enhances the effectiveness and efficiency of soil remediation.

[0027] In summary, the present application has the following beneficial effects:

[0028] 1. Through the synergistic effect of the cutting assembly and the soil turning assembly, the weeds on the soil surface are first cleaned and the soil is loosened; next, the soil remediation liquid in the storage tank is delivered to the inside of the external sleeve through the injection pipe by the negative pressure pump; in this process, the high pressure generated by the inflator causes the treatment agent to be released through the overflow hole; combined with the centrifugal rotation of the external sleeve, the treatment agent can be thrown into the loosened soil, which effectively sprays the agent into deeper soil, thereby ensuring the effect of soil pollution treatment; this method not only improves the penetration ability of the agent, but also helps to enhance its treatment efficiency of pollutants.

[0040] As shown in the figure, Figure 2 The cutting wheel 407 is provided with two cutting wheels 407, and the rotating directions of the two cutting wheels 407 on the horizontal plane are opposite, that is, one cutting wheel 407 rotates counterclockwise and the other cutting wheel 407 rotates clockwise; due to this configuration of the cutting wheel 407, the two cutting wheels 407 will interact during the cutting process, optimizing the cutting effect; due to the opposite rotating directions of the two cutting wheels 407, the force generated during the cutting process can form a self-balancing state; this design can reduce the torsional moment of the equipment during work, thereby reducing the stress concentration on the structure; the two cutting wheels 407 simultaneously perform cutting operations and enhance the cutting effect through opposite directions; the two wheels alternately act on the soil and plants, which can more evenly process the cutting area and improve the cutting area per unit time.

[0041] As shown in the figure, Figure 2As shown, the cutting assembly 4 further comprises a pneumatic cylinder 408 arranged on the transverse support frame 3, the pneumatic cylinder 408 is hingedly arranged between the transverse support frame 3, and the output end of the pneumatic cylinder 408 is hingedly arranged with the middle part of the first mounting rod 403, the first transversely extending rod 401 and the second transversely extending rod 402 are both rotationally connected with the transverse support frame 3 through the rotation shaft 409, through the extension and contraction of the pneumatic cylinder 408, the first transversely extending rod 401 and the second transversely extending rod 402 are arranged to overturn around the central axis of the rotation shaft 409, so as to adjust the cutting direction of the cutting wheel 407, this design allows the cutting direction and cutting depth of the cutting wheel 407 to be quickly and accurately adjusted under different working conditions, and provides greater adaptability for working on complex terrain or different plant heights; by adjusting the cutting direction, the cutting wheel 407 can be cut at the best angle according to different needs, achieving better cutting effect, which can effectively process different types of vegetation or soil and ensure the uniformity of the working effect.

[0042] As shown in Figure 2 and Figure 3 , the soil turning assembly 5 is provided with at least two groups, specifically, the soil turning assembly 5 comprises a first support side frame 501 fixedly installed at the bottom of the transverse support frame 3, the first support side frame 501 is provided with two, and a first rotating rod 502 is arranged between the two first support side frames 501, a first land roller 503 is installed on the outer side of the first rotating rod 502, and a plurality of first land hooks 504 are uniformly distributed on the outer surface of the first land roller 503, which can act on the soil through tangential motion when rotating to form a plowing force and achieve the effect of turning over the soil; the cutting and overturning of the soil by the first land hooks 504 can more quickly and uniformly loosen the soil, creating better soil conditions for subsequent soil remediation.

[0043] As shown in Figure 3 , a mud guide plate 505 is further arranged between the two first support side frames 501, the mud guide plate 505 is located obliquely above the first land roller 503, a guide slope is arranged on the inner surface of the mud guide plate 505, a vibration plate 506 is movably installed on the guide slope of the mud guide plate 505, and a vibration assembly is arranged between the vibration plate 506 and the mud guide plate 505 for vibration of the vibration plate 506. During the rotation of the first land roller 503, it is inevitable that the soil will hit the guide slope of the mud guide plate 505, and through the vibration assembly, the vibration plate 506 is vibrated at high frequency to break the soil hitting the mud guide plate 505 and re-direct it to the ground.

[0044] As shown in Figure 3As shown, the guide plate 505 is located obliquely above the first land plane 503, and the inner surface thereof has a guide slope; the main function of the guide plate 505 is to guide the loose and impacted soil during the turning process to move towards the ground direction; the vibration assembly is installed between the guide plate 505 and the vibration plate 506, so that the vibration plate 506 can vibrate at high frequency; the vibration is usually generated by electric or pneumatic driving, so that the vibration plate 506 moves on the slope of the guide plate 505; during the rotation of the first land plane 503, the soil will impact the guide slope of the guide plate 505; through vibration, the vibration plate 506 applies additional energy to the impacted soil, so as to realize the vibration crushing of the soil; the crushed soil is re-directed and falls back to the ground due to the vibration, forming a more uniform soil surface layer.

[0045] As shown in Figure 3 , the high-frequency vibration of the vibration plate 506 breaks the impacted soil, increases the looseness of the soil, and improves the permeability of the soil, so that the subsequent treatment agent can penetrate into the deep soil more easily; after the soil is crushed, the particles become smaller and more uniform, increasing the surface area of the soil contacted by the treatment agent, optimizing its distribution and reaction in the soil, and improving the application effect.

[0046] As shown in Figure 3 , the guide plate 505 is provided with a second support side frame at the end position of the guide slope, and the second support side frame is provided with two second support side frames, and a second rotating rod is arranged between the two second support side frames, and a second land plane 507 is installed on the outer side of the second rotating rod, and a plurality of second land hooks 508 are uniformly distributed on the outer surface of the second land plane 507, and the cross section of the second land plane 507 is smaller than that of the first land plane 503, and the number of the second land hooks 508 is higher than that of the first land hooks 504; the preliminary treatment of the first land plane 503 and the vibration plate 506 has preliminarily broken and loosened the soil; the introduction of the second land plane 507 enables the plowing process to be carried out in layers, further improving the plowing effect of the soil; the second land hooks 508 uniformly distributed on the outer surface of the second land plane 507 are designed to help break and loosen the soil more fully; a higher number of hooks means that more soil can be contacted and treated in each operation, thereby realizing more detailed plowing; the introduction of the second land plane 507 enables the further crushing of the soil to be more thorough, and the clumps in the soil are identified and removed, which helps to improve the soil structure; after the treatment of the first land plane 503, the second land plane 507 can penetrate deeper into the soil, break the compacted layer of the soil, and improve the air permeability and water permeability of the soil, which is beneficial to the better penetration of the treatment agent.

[0047] As shown in Figure 4 and Figure 5As shown, the drug administration assembly 6 includes a mounting frame 601, an inflator 602 arranged on the mounting frame 601, and a storage tank 603 for storing soil remediation liquid, the bottom of the mounting frame 601 is provided with a mounting side plate 604, the mounting side plate 604 is provided with a driving member and a rotatable external sleeve 605, the driving member is used to drive the external sleeve 605, one end of the external sleeve 605 is provided with an inflation tube 606, the other end of the external sleeve 605 is provided with a dosing tube 607, wherein the inflation tube 606 is connected with an output end of the inflator 602, the dosing tube 607 and an output end of the storage tank 603 are connected through a negative pressure pump, the outer surface of the external sleeve 605 is uniformly provided with a plurality of overflow holes, through the negative pressure pump, the soil remediation liquid in the storage tank 603 is injected into the inside of the external sleeve 605 through the dosing tube 607, and the high pressure generated in the external sleeve 605 by the inflator 602 is used to make the soil remediation liquid discharge through the overflow holes, and the centrifugal rotation of the external sleeve 605 is used to make the soil remediation liquid be thrown into the broken soil.

[0048] As shown in Figure 4 and Figure 5 , the negative pressure pump is used to extract the soil remediation liquid in the storage tank 603 and deliver it to the inside of the external sleeve 605 through the dosing tube 607; the formation of negative pressure can effectively suck the liquid into the pipeline, ensuring the stable delivery of the medicament; and the main function of the inflator 602 is to inflate gas into the external sleeve 605, thereby generating high pressure; such high-pressure gas will push the medicament in the external sleeve 605 to discharge through the overflow holes; this process can be understood as using pressure difference to promote the injection of the medicament; the design of the external sleeve 605 ensures that it can rotate; the medicament is thrown out and dispersed into the surrounding broken soil under the pushing of the high-pressure gas and the centrifugal action of the external sleeve 605; this way not only enhances the coverage of the medicament, but also helps the medicament mix effectively with the soil; effectively improves the delivery speed and efficiency of the soil remediation liquid, realizes rapid coverage and uniform application.

[0049] As shown in Figure 4 and Figure 5 , specifically, the two ends of the external sleeve 605 are connected with the inflation tube 606 and the dosing tube 607 through bearings 608 respectively, which can effectively avoid the winding of the inflation tube 606 and the dosing tube 607 caused by the rotation of the external sleeve 605.

[0050] As shown in Figure 4 and Figure 5As shown, the outer surface of the external sleeve 605 is fixedly installed with a plurality of guide wheels 609, the surface of the plurality of guide wheels 609 is provided with a raised stripe 6010, the side surface of the raised stripe 6010 is provided with a strip-shaped channel 6011, the strip-shaped channel 6011 is communicated with the overflow hole through a connecting pipe, and the soil remediation liquid overflowing in the overflow hole enters the inside of the strip-shaped channel 6011 of the raised stripe 6010 through the connecting pipe, so that the soil remediation liquid overflows from the direction of the raised stripe 6010, forming a horizontal spraying path. By starting the outlet of the strip-shaped channel 6011 on the side surface of the raised stripe 6010, on the one hand, the soil can be effectively prevented from blocking the overflow hole; on the other hand, this structure can ensure that the pesticide does not vertically drop, but is sprayed in a horizontal direction, thereby forming a spraying path that can cover a larger pesticide application area; the spraying direction of the soil remediation liquid can be accurately controlled, ensuring that the pesticide is evenly distributed in the application area and improving the effect of pesticide application.

[0051] As shown in Figure 4 and Figure 5 , the mounting bracket 601 is provided with an arc-shaped baffle 6012 located directly above the guide wheel 609, and the lower surface of the arc-shaped baffle 6012 is provided with an air outlet hole, and the air outlet direction of the air outlet hole is inclined towards the ground. The inside of the arc-shaped baffle 6012 is provided with an air outlet pipe 6013 connected with the air outlet hole, and the air outlet pipe 6013 is connected between the other output end of the inflator 602.

[0052] As shown in Figure 4 and Figure 5 , the arc-shaped baffle 6012 is located directly above the guide wheel 609, which can form a physical barrier to block the upward spraying of the pesticide; at the same time, through the arc-shaped design, the arc-shaped baffle 6012 can effectively guide the pesticide to flow along the set direction; the air outlet direction of the air outlet hole is inclined towards the ground, so that the sprayed pesticide is mainly applied downward through the inclined angle, rather than vertically upward diffusion; this can effectively control the spraying range; by connecting the output of the inflator 602 with the air outlet hole through the air outlet pipe 6013, the airflow can be enhanced during pesticide application, further ensuring that the pesticide is sprayed towards the ground.

[0053] As shown in Figure 4 and Figure 5 , by guiding the spraying direction of the pesticide downward, the upward diffusion of the pesticide can be effectively prevented, avoiding pollution to the surrounding environment, especially during pesticide application; inhibiting the upward diffusion of the pesticide can avoid waste in the air, ensuring that more pesticide is used for soil treatment, thereby improving its economic efficiency; avoiding the upward diffusion of the pesticide reduces the impact on non-target plants or organisms, such as avoiding potential harm to insects in the air or nearby crops, reducing the risk of environmental pollution.

[0054] Working principle: According to the moving direction of the track wheel 2, the soil pollution treatment device is moved to the soil area to be treated. The device relies on the cooperation of the cutting assembly 4 and the soil turning assembly 5 to first remove weeds on the surface of the soil and loosen the soil. Subsequently, the negative pressure pump delivers the soil remediation liquid in the storage tank to the inside of the external sleeve 605 through the injection pipe 607. In this process, the high pressure generated by the inflator 602 causes the treatment agent to be released through the overflow hole, while the centrifugal rotation of the external sleeve 605 allows the treatment agent to be thrown into the loosened soil. This process effectively sprays the treatment agent to a deeper level of the soil, thereby ensuring the effect of soil pollution treatment. This method not only improves the penetration ability of the agent, but also enhances its treatment efficiency on pollutants.

[0055] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
