Description

Technical Field

[0001] The invention relates to the technical field of soil remediation, and in particular to a surface soil conditioning and remediation system. Background Art

[0002] With the gradual increase in the rate of soil pollution in cultivated land in recent years, the soil pollution problem caused by the promotion and application of synthetic fertilizers and pesticides has attracted more and more attention. Soil conditioning and remediation is one of the important technical measures to restore the normal function of polluted soil. It refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil or to change the soil texture to make it suitable for crop growth.

[0003] Traditional soil conditioning methods include the imported soil method and the soil layer mixing method. If there is clay, clay soil, or river mud near the sandy land, the imported soil method can be used to improve the soil year by year to reach a loam texture range of three muds and seven sands or four muds and six sands. However, this method has a large amount of work and low operating efficiency, and is not suitable for large-scale soil texture improvement. The soil layer mixing method is to press the sand or press the silt by turning over the silt. If there is a silt layer not deep under the surface of the sandy soil, and a sandy soil layer not deep under the surface of the clay, deep turning or large uncovering can be used to turn the sand and clay layers to the surface, and the upper and lower sand and clay are mixed by plowing and harrowing to change the soil quality. Generally, the soil parent material in alluvial plains has different layers, and this method can be used to improve the surface soil texture. However, it is required that the texture of the upper and lower layers of soil is significantly different, and the underlying soil layer should not be too deep. Generally, it should not be too deep. Burying too deep will make it too difficult to turn over and press.

[0004] From the above technical content, we can know that the existing soil conditioning methods have the defects of large engineering workload and low operating efficiency, have certain requirements on the environment, and have a relatively limited scope of application. Summary of the invention

[0005] In view of this, the present invention aims to propose a surface soil conditioning and repair system, which can improve soil texture and transform it into soil suitable for the growth of specific types of crops, and has the advantages of high operating efficiency and a wide range of applications.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A surface soil conditioning and repair system comprises a frame which is slidably arranged on a traction device along a vertical direction;

[0008] A sandbox, fixedly arranged at one end of the top of the frame;

[0009] A stirring shaft is rotatably arranged on the sandbox around its own axis;

[0010] A rotary drilling assembly is arranged at the bottom of the frame in a horizontal direction;

[0011] A driving assembly is arranged on the top of the sand box and is connected to the stirring shaft and the rotary drilling assembly, and is used for driving the stirring shaft and the rotary drilling assembly to rotate synchronously.

[0012] Furthermore, the rotary drilling assembly includes a guide cover fixedly connected to the bottom of the frame;

[0013] A support ring, fixedly connected to the bottom of the frame;

[0014] The rotary drilling shaft is rotatably arranged on the support ring around its own axis direction;

[0015] One end of the rotary drilling shaft away from the sand box is connected to the driving assembly and can rotate under the action of the driving assembly.

[0016] Furthermore, the stirring shaft includes a shaft body, which is rotatably arranged on the sandbox along a vertical direction;

[0017] The stirring sleeve is sleeved on one end of the shaft body close to the rotary drilling shaft and rotates synchronously with the shaft body.

[0018] Furthermore, the portion of the shaft body located inside the sandbox has a protrusion, and the protrusion is evenly distributed along the circumference of the shaft body.

[0019] Further, the driving assembly includes a reduction motor, which is arranged on the top of the sandbox;

[0020] A first driving shaft is arranged on the top of the sand box and rotates in a horizontal direction, one end of which is connected to the reduction motor and the other end of which is connected to the rotary drilling shaft chain;

[0021] A second drive shaft is arranged on the top of the sandbox for rotation in a vertical direction.

[0022] One end is connected to the reduction motor, and the other end is connected to the shaft through a coupling.

[0023] Furthermore, a plurality of support plates are vertically arranged on the top of the frame, and the first drive shaft passes through the support plates.

[0024] Furthermore, a feeding pipe is provided on the top of the sand box and is connected to the interior of the sand box.

[0025] Furthermore, a guide plate is obliquely arranged inside the sand box, and the higher end of the guide plate is opposite to the feeding pipe.

[0026] Furthermore, a plurality of lifting ears are provided on the top of the rack and are symmetrically distributed about the geometric center of the rack.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] A surface soil conditioning and repair system in the present invention, wherein the frame can support and limit other parts of the structure, and at the same time can flatten the mixed conditioned soil. The sandbox can be used as a container for building sand for soil improvement, and plays a role of temporary storage and directional feeding. The stirring shaft passing through the sandbox can evenly mix the building sand and the surface soil excavated by the rotary drilling component under the action of the driving component. The rotary drilling component can excavate the surface soil of the ground and push it in the direction of the stirring shaft under the action of the driving component. The driving component can provide power for the synchronous operation of the stirring shaft and the rotary drilling component. The purpose of soil conditioning is achieved by mixing and stirring the building sand and the surface soil in a certain proportion. The whole process has a high degree of mechanization and high operating efficiency, and it gets rid of the dependence of traditional soil conditioning methods on environmental conditions and has a wider range of applications.

[0029] Secondly, by setting the rotary drilling assembly as a structure of a guide cover, a support ring and a rotary drilling shaft, the guide cover guides the excavated soil during the process of the rotary drilling shaft excavating the soil and fixes the installation of the support ring. The setting of the support ring enables the rotary drilling shaft to rotate in a direction parallel to the horizontal plane. When the rotary drilling shaft rotates under the action of the driving assembly, the rotary drilling blades and the ground soil are excavated and pushed to the bottom of the sandbox.

[0030] Thirdly, by configuring the stirring shaft to be a shaft body and a stirring sleeve structure, the shaft body connected to the driving assembly can transmit torque to the stirring sleeve, so that the stirring sleeve can rotate synchronously around the axis of the shaft body. As the stirring sleeve rotates with the shaft body, the soil and building sand under the sandbox can be evenly mixed. The sleeve structure of the stirring sleeve is not only convenient for replacement and maintenance, but also not easily blocked by sand and soil.

[0031] By providing a protrusion on the side wall of the outer surface of the shaft located on the inner side of the sand box, the construction sand temporarily stored inside the sand box can be stirred so that the construction sand can flow smoothly to the outside of the sand box, which helps to improve the stability of the sand supply speed of the sand box and helps to reduce the possibility of construction sand condensing inside the sand box and blocking the outlet.

[0032] By configuring the drive assembly to be a structure of a reduction motor, a first drive shaft, and a second drive shaft, the reduction motor has a greater driving force than an ordinary motor. The first drive shaft and the second drive shaft can transmit the torque of the reduction motor to the agitator shaft and the rotary drilling assembly respectively, so that the agitator shaft and the rotary drilling assembly can operate synchronously at a certain speed ratio, so that the excavation process and the agitation process can be better coordinated, and the soil conditioning effect can be improved. The dual drive shaft setting reduces the number of motors required by the system as a whole, facilitates equipment maintenance and commissioning, and reduces the cost of equipment operation.

[0033] By arranging a support plate on the top of the frame and passing the first drive shaft through the support plate, the frame can support the first drive shaft through the support plate, so that the operation of the first drive shaft is more stable, which is conducive to reducing the vibration of the first drive shaft and the rotary drilling assembly chain transmission connection section. By symmetrically arranging lifting ears perpendicular to the frame at both ends of the frame, it is convenient to hoist, disassemble and adjust the height of the entire equipment.

[0034] By setting a feeding pipe on the top of the sandbox, it is convenient to add construction sand into the sandbox. When the operation time is long, you can add construction sand directly to the feeding pipe to ensure the continuity of the operation process and further improve the overall operation efficiency of the system. The guide plate installed obliquely inside the sandbox makes the construction sand in the sandbox flow to the sandbox outlet more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following will refer to the attached Figure 1 To Attachment Figure 5 The present invention is described in detail with reference to embodiments.

[0052] The present embodiment relates to a surface soil conditioning and repair system, which can improve soil texture and transform it into soil suitable for the growth of specific types of crops, and has the advantages of high operating efficiency and a wide range of applications.

[0053] In terms of overall structure, refer to Figure 1 A surface soil conditioning and remediation system of this embodiment includes a frame 1, a sand box 2, a stirring shaft 3, a rotary drilling assembly 4 and a driving assembly 5. Among them, the frame 1 is slidably arranged on the traction device along the vertical direction. The sand box 2 is fixedly installed at one end of the top of the frame 1, and the stirring shaft 3 is vertically penetrated through the sand box 2. The stirring shaft 3 is rotatably arranged on the sand box 2 and can rotate around its own axis. The rotary drilling assembly 4 is arranged at the bottom of the frame 1 along the horizontal direction. The driving assembly 5 is respectively connected to the stirring shaft 3 and the rotary drilling assembly 4, and can drive the stirring shaft 3 and the rotary drilling assembly 4 to rotate.

[0054] The frame 1 can support and limit other parts of the structure, and can also flatten the mixed tempered soil. The sandbox 2 can be used as a container for building sand for soil improvement, and can be used for temporary storage and directional feeding. The stirring shaft 3 inserted in the sandbox 2 can evenly mix the building sand and the surface soil excavated by the rotary drilling component 4 under the action of the driving component 5. The rotary drilling component 4 can excavate the surface soil of the ground and push it in the direction of the stirring shaft 3 under the action of the driving component 5. The driving component 5 can provide power for the synchronous operation of the stirring shaft 3 and the rotary drilling component 4. By mixing and stirring the building sand and the surface soil in a certain proportion, the purpose of soil conditioning is achieved. The whole process has a high degree of mechanization and high operating efficiency, and it has gotten rid of the dependence of the traditional soil conditioning method on environmental conditions and has a wider range of applications.

[0055] Reference Figure 1 and Figure 2In this embodiment, the rotary drilling assembly 4 includes a guide cover 401, a support ring 402 and a rotary drilling shaft 403. Among them, the guide cover 401 can be a thin metal plate with an arc-shaped cross section. The guide cover 401 and the frame 1 are fixedly connected by welding a rectangular metal plate. The support ring 402 is fixedly arranged below the guide cover 401. The center of the circle of the support ring 402 is concentrically arranged with the center of the circle corresponding to the arc line of the cross section of the guide cover 401. The rotary drilling shaft 403 consists of a cylindrical solid metal shaft and a rotary drilling blade spirally arranged on the metal shaft. The rotary drilling shaft 403 is vertically penetrated and rotatably arranged on the support ring 402. A ball bearing for supporting and restraining the rotation of the rotary drilling shaft 403 is installed in the support ring 402. A sprocket is provided at one end of the rotary drilling shaft 403 away from the sand box 2, which is connected to the drive assembly 5 by chain transmission to realize power transmission.

[0056] By configuring the rotary drilling assembly 4 to include a guide cover 401, a support ring 402, and a rotary drilling shaft 403, the guide cover 401 guides the excavated soil during the process of the rotary drilling shaft 403 excavating the soil, and fixes the installation of the support ring 402. The configuration of the support ring 402 enables the rotary drilling shaft 403 to rotate in a direction parallel to the horizontal plane. When the rotary drilling shaft 403 rotates under the action of the driving assembly 5, the rotary drilling blades and the ground soil are excavated and pushed to the bottom of the sandbox 2.

[0057] Reference Figure 1 and Figure 3 , the stirring shaft 3 includes a shaft body 301 and a stirring sleeve 302. The shaft body 301 can be a metal shaft that is rotated and passed through the sandbox 2 in a direction perpendicular to the ground. The end of the shaft body 301 close to the ground extends to the bottom of the sandbox 2, and the stirring sleeve 302 is sleeved on the end of the shaft body 301 close to the rotary drilling shaft 403, that is, the shaft body 301 extends to the end of the ground below the sandbox 2. The stirring sleeve 302 includes a sleeve in the middle and three rectangular metal frames uniformly distributed on the outer wall of the sleeve along the circumferential direction. The shaft body 301 is passed through the sandbox 2, and a protrusion is provided on the side wall of the outer surface of the part of the shaft body 301 located on the inner side of the sandbox 2. The number of protrusions can be set to multiple. Multiple protrusions are evenly distributed along the circumference of the outer surface side of the shaft body 301.

[0058] By setting the stirring shaft 3 to a structure of a shaft body 301 and a stirring sleeve 302, the shaft body 301 connected to the driving assembly 5 can transmit torque to the stirring sleeve 302, so that the stirring sleeve 302 rotates synchronously around the axis of the shaft body 301. The stirring sleeve 302 can evenly stir the soil and building sand below the sandbox 2 as the shaft body 301 rotates. The sleeve structure of the stirring sleeve 302 is not only convenient for replacement and maintenance, but also not easily blocked by sand and soil.

[0059] By providing a raised portion on the side wall of the outer surface of the shaft 301 located inside the sand box 2, the construction sand temporarily stored inside the sand box 2 can be stirred so that the construction sand can flow smoothly to the outside of the sand box 2, which helps to improve the stability of the sand supply speed of the sand box 2 and helps to reduce the possibility of construction sand condensing inside the sand box 2 and blocking the outlet.

[0060] Reference Figure 1 and Figure 4 The driving assembly 5 includes a reduction motor 501, a first driving shaft 502 and a second driving shaft 503. The reduction motor 501 is composed of a driving motor and a worm gear reversing reducer. One end of the first driving shaft 502 and the second driving shaft 503 are both connected to the power output end of the reduction motor 501. The first driving shaft 502 is arranged to rotate horizontally at the top of the sandbox 2, and the end of the first driving shaft 502 away from the sandbox 2 is connected to the rotary drilling assembly 4 by a chain drive connection. The second driving shaft 503 is vertically arranged at the top of the sandbox 2, and the second driving shaft 503 is connected to the stirring shaft 3 by a coupling.

[0061] By configuring the drive assembly 5 to be a structure of a reduction motor 501, a first drive shaft 502, and a second drive shaft 503, the reduction motor 501 has a greater driving force than an ordinary motor. The first drive shaft 502 and the second drive shaft 503 can transmit the torque of the reduction motor 501 to the stirring shaft 3 and the rotary digging assembly 4, respectively, so that the stirring shaft 3 and the rotary digging assembly 4 can operate synchronously at a certain speed ratio, so that the excavation process and the stirring process can be better coordinated, and the effect of soil conditioning can be improved. The dual drive shaft configuration reduces the number of motors required by the system as a whole, facilitates equipment maintenance and commissioning, and reduces the cost of equipment operation.

[0062] Reference Figure 1 , a plurality of support plates 101 are vertically arranged on the top of the frame 1. The first drive shaft 502 is passed through the support plates 101. A plurality of lifting ears 102 are vertically fixedly arranged at both ends of the frame 1. The plurality of lifting ears 102 are symmetrically distributed about the geometric center of the frame 1.

[0063] By arranging a support plate 101 on the top of the frame 1 and allowing the first drive shaft 502 to pass through the support plate 101, the frame 1 can form a support effect on the first drive shaft 502 through the support plate 101, so that the operation process of the first drive shaft 502 is more stable, which is conducive to reducing the vibration of the first drive shaft 502 and the chain transmission connection section of the rotary drilling assembly 4. By symmetrically arranging the lifting ears 102 perpendicular to the frame 1 at both ends of the frame 1, it is convenient to hoist, disassemble and adjust the height of the entire equipment.

[0064] Reference Figure 1 and Figure 5The sandbox 2 can be a hollow metal box. A feeding pipe 201 is provided on the top of the sandbox 2. The feeding pipe 201 can be a metal pipe with a rectangular cross section and tilted at a certain angle to the horizontal direction. A guide plate 202 is tilted inside the sandbox 2. There is a certain angle between the guide plate 202 and the horizontal plane. The end of the guide plate 202 with a higher height in the vertical direction is opposite to the connecting port of the feeding pipe 201 and the sandbox 2.

[0065] By setting a feeding pipe 201 on the top of the sandbox 2, it is convenient to add construction sand into the sandbox 2. When the operation time is long, the construction sand can be directly added to the feeding pipe 201 to ensure the continuity of the operation process and further improve the overall operation efficiency of the system. The guide plate 202 installed obliquely inside the sandbox 2 makes the process of the construction sand in the sandbox 2 flowing to the outlet of the sandbox 2 smoother.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
