Description

Technical Field

[0001] The present invention belongs to the technical field of ecological restoration, and particularly relates to a high-efficiency mixing device for soil repair agents. Background Art

[0002] Ecological restoration is a comprehensive method for repairing polluted environments under the guidance of ecological principles, based on bioremediation, combined with various physical, chemical, and engineering technical measures, and optimized to achieve the best results and the lowest cost. The successful implementation of ecological restoration requires the participation of multiple disciplines such as ecology, physics, chemistry, botany, microbiology, molecular biology, cultivation, and environmental engineering.

[0003] In the process of soil repair, soil repair substances can be mixed into the soil for repair. However, most of the existing soil repair devices are difficult to quickly and efficiently repair large areas of soil.

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0065] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0066] Referring to Figures 1 to 10 , the present invention discloses a high-efficiency mixing device for soil conditioners, including:

[0067] Vehicle body 1;

[0068] The rotary tillage device 2 is located at the front end in the traveling direction of the vehicle body 1. The rotary tillage device 2 is connected to the vehicle body 1 and is used for breaking up the soil body;

[0069] The soil shoveling device 3 has its feeding end communicated with the discharging end of the rotary tillage device 2. The soil shoveling device 3 is connected to the vehicle body 1;

[0070] The conveyor belt assembly 4 has its feeding end communicated with the discharging end of the soil shoveling device 3. The conveyor belt assembly 4 is used for conveying the soil body. One end of the conveyor belt assembly 4 is connected to the soil shoveling device 3;

[0071] The soil conditioner mixing device 5 has its feeding end communicated with the discharging end of the conveyor belt assembly 4. The other end of the conveyor belt assembly 4 is connected to the soil conditioner mixing device 5. The soil conditioner mixing device 5 is used for mixing the soil and the conditioner evenly;

[0072] The spreading device 6 has its feeding end communicated with the discharging end of the soil conditioner mixing device 5. The spreading device 6 is connected to the vehicle body 1. The discharging end of the spreading device 6 faces the ground surface and is used for spreading the soil mixed with the conditioner on the ground surface.

[0073] During use, by moving the vehicle body 1, the soil body is chopped by the rotary tillage device 2 during the forward movement of the vehicle body 1 and is conveyed to the soil shoveling device 3. After the soil shoveling device 3 shovels up the broken soil blocks, as the vehicle body 1 moves forward, the broken soil blocks automatically move towards the conveyor belt assembly 4 and are conveyed to the soil conditioner mixing device 5 through the conveyor belt assembly 4. The mixing of the conditioner and the soil is realized in the soil conditioner mixing device 5. After the mixing is completed, the soil containing the conditioner is spread on the ground surface through the spreading device 6, completing the soil remediation of this area. The operator can automatically complete the in-situ mixing of the soil conditioner with the soil body by driving the vehicle body 1, realizing soil remediation. Compared with the traditional method that requires manual excavation and mixing of the soil layer and then laying, this device has the characteristics of simple operation and high remediation efficiency.

[0074] The rotary tillage device 2 mentioned in this device, also known as a rotary tiller or rotary cultivator, is a soil tillage machine with rotary blades as the core working components. Its structure mainly consists of a frame, a transmission system (including a power input shaft, a gearbox, a gearbox, and a universal joint, etc.), a tool shaft, rotary tillage blades (common types include sickle blades, chisel blades, right-angle blades, and arc blades), a soil retaining housing, a land leveling drag plate, and a depth limiting device (such as a depth limiting wheel or a drag plate), etc. This device drives the blades to rotate at a high speed through the tool shaft (usually at a speed of 190 - 280 revolutions per minute), and realizes tillage by using the cutting and throwing actions of the blades on the soil. Its core functions include completing plowing and harrowing operations at one time, effectively breaking the plow sole to restore the soil tillage layer structure, enhancing the soil's water storage and moisture retention capacity, chopping the stubble below the ground surface and leveling the land, while reducing the breeding of pests, diseases, and weeds, and creating an ideal seedbed for subsequent sowing. Its working principle is based on power transmission and mechanical design: the power of the tractor drives the tool shaft to rotate through a universal shaft, and the blades cut into the soil along a rotation trajectory consistent with the forward direction of the tractor. The reaction force generated during the cutting process can assist in pushing the unit forward. The soil clods after soil fragmentation are broken again by colliding with the mudguard, and then the ground surface is scraped flat by the drag plate. The tillage depth is adjusted by the height of the depth limiting wheel or the contact surface of the drag plate (12 - 25 cm for dry tillage, 14 - 18 cm for wet tillage). According to the tool shaft configuration method, it can be divided into three types: horizontal shaft type (horizontally arranged, with strong soil fragmentation ability, suitable for reclaiming shrublands and conventional farmlands), vertical shaft type (vertically rotating, with good slurry-raising effect, suitable for paddy field tillage), and inclined type (the tool shaft is inclinedly installed, reducing tillage resistance). Among them, the horizontal shaft type is the most widely used, and the vertical shaft type has a higher popularity in paddy field areas such as Japan. Modern rotary tillers have developed towards combined operations (integrating functions such as sowing and fertilizing), wide-width high-speed, and energy-saving, and have become an important equipment in the modern agricultural mechanization production system.

[0075] By organically combining the structure of the modern rotary tillage device 2 with this device, function combination is achieved.

[0076] As an optional implementation manner, the soil conditioner mixing device 5 includes a stone separation component and a conditioner mixing component. The feed end of the stone separation component is communicated with the discharge end of the conveyor belt component 4, the stone discharge end of the stone separation component is communicated with the ground surface, and the soil clod discharge end of the stone separation component is communicated with the feed end of the conditioner mixing component.

[0077] Since the soil contains stones and soil clods, the stones cannot be chopped and processed, nor can they act with the conditioner. Therefore, before the soil is mixed with the conditioner, the stones need to be separated. This device first separates the stones from the soil clods through the stone separation component, and then makes the soil clods enter the conditioner mixing component.

[0078] As an optional implementation manner, the stone separation component includes:

[0079] The feed cylinder 501 is fixedly connected to the bottom of the vehicle body 1 through a support arm 508. Soil and stone inlets 503 and a stone outlet 502 are respectively arranged on both sides of the feed cylinder 501. The soil and stone inlet 503 is communicated with the discharge end of the conveyor belt assembly 4.

[0080] The rotating shaft 504 has its bottom end rotatably connected to the inner wall of the bottom of the feed cylinder 501. The top end of the rotating shaft 504 is drivingly connected to the repair agent mixing assembly. A screw conveyor 523 is sleeved on the outer side of the bottom of the rotating shaft 504. The conveying direction of the screw conveyor 523 is upward. The screw conveyor 523 is axially connected to the rotating shaft 504.

[0081] The lifting cylinder 505 is vertically slidably connected inside the feed cylinder 501. The feed cylinder 501 and the lifting cylinder 505 are coaxially arranged. The lifting cylinder 505 is drivingly connected to the rotating shaft 504. The rotating shaft 504 drives the lifting cylinder 505 to lift and lower repeatedly.

[0082] The screen 507 is sleeved on the outer side of the lifting cylinder 505. The screen 507 is fixedly connected to the lifting cylinder 505. The screen 507 is inclined. The high end of the screen 507 is communicated with the soil and stone inlet 503. The low end of the screen 507 is communicated with the stone outlet 502.

[0083] The vibration part is drivingly connected to the screen 507.

[0084] The feed end of the screw conveyor 523 is communicated with the bottom chamber of the feed cylinder 501. The feed end of the screw conveyor 523 is located below the screen 507.

[0085] As an optional implementation manner, the vibration part includes two vibrators 506. The two vibrators 506 are respectively arranged on the top and bottom of the screen 507. The vibrators 506 are in contact with the screen 507. The two vibrators 506 alternately contact the top or bottom surface of the screen 507. One of the vibrators 506 is fixedly connected below the soil and stone inlet 503, and the other vibrator 506 is fixedly connected below the stone outlet 502.

[0086] The specific working process is as follows:

[0087] The mixture of soil clods and stones enters the feed cylinder 501 from the soil and stone inlet 503 at the same time. At this time, due to the action of the rotating shaft 504, the lifting cylinder 505 reciprocates up and down. The lifting cylinder 505 drives the screen 507 to reciprocate up and down in the feed cylinder 501. The screen 507 is inclined. Both the soil clods and the stones can roll along the screen 507. During the up and down movement of the screen 507, the two vibrators 506 alternately contact the top or bottom surface of the screen 507 to vibrate the screen 507. The high-frequency vibration of the screen 507 can vibrate and disperse the soil clods, while the stones cannot be dispersed and will be discharged from the stone outlet 502.

[0088] The filtered soil residues enter below the screen 507 and are conveyed upward by the screw conveyor 523 into the repair agent mixing assembly.

[0089] As an optional embodiment, the repair agent mixing component includes:

[0090] The chassis 510 is an annular structure. The chassis 510 is coaxially arranged with the lifting cylinder 505 and the rotating shaft 504. The chassis 510 and the lifting cylinder 505 are vertically slidably matched. The outer side of the chassis 510 is coaxially sleeved with a stirring inner barrel 512. The stirring inner barrel 512 is fixedly connected to the chassis 510;

[0091] The stirring outer barrel 511 is coaxially sleeved on the outer side of the stirring inner barrel 512. The top of the stirring inner barrel 512 is fixedly connected to the inner wall of the top of the stirring outer barrel 511. The stirring outer barrel 511 is fixed to the vehicle body 1. A gap is set between the inner wall of the stirring outer barrel 511 and the outer wall of the stirring inner barrel 512. A spacer ring 519 is provided in the middle of the gap. The spacer ring 519 is coaxially sleeved on the outer side of the stirring inner barrel 512. The spacer ring 519 divides the gap into a repairing agent chamber 526 located at the top and an extrusion chamber 527 located at the bottom. The liquid outlet end of the repairing agent chamber 526 and the liquid inlet end of the extrusion chamber 527 are connected through a plurality of one-way valves 521, and the liquid outlet end of the extrusion chamber 527 is connected to the inner side of the stirring inner barrel 512 through a plurality of one-way valves 522;

[0092] A plurality of one-way valves 521 are embedded in the spacer ring 519 at equal intervals in the circumferential direction;

[0093] A plurality of one-way valves 522 are embedded in the side wall of the mixing inner barrel 512 at equal intervals in the circumferential direction;

[0094] The piston ring 520 is sleeved on the outer side of the mixing inner barrel 512. The piston ring 520 is vertically slidably arranged in the extrusion chamber 527. The outer wall of the piston ring 520 contacts and slides with the inner wall of the mixing outer barrel 511. The piston ring 520 is transmission-connected to the lifting cylinder 505.

[0095] A stirring assembly is arranged inside the stirring inner barrel 512, and the stirring assembly is drivingly connected to the rotating shaft 504;

[0096] The top discharge end of the mixing inner barrel 512 is connected to the feed end of the spreading device 6;

[0097] The top end of the rotating shaft 504 is axially connected to the output shaft of the motor three 514 , and the fixed end of the motor three 514 is fixedly connected to the outer side of the top of the mixing outer barrel 511 .

[0098] The specific working process of the repair agent mixing component is:

[0099] The motor 3 514 drives the rotating shaft 504 to rotate. During the rotation of the rotating shaft 504, the auger 523 is driven to rotate and the lifting cylinder 505 is driven to lift and reciprocate.

[0100] The auger 523 transports the soil into the mixing inner barrel 512 and drives the mixing assembly to stir the soil through the rotating shaft 504 .

[0101] The repair agent chamber 526 is filled with a repair agent and is connected to the extrusion chamber 527 through a one-way valve 521. The lifting cylinder 505 drives the piston ring 520 to move in the extrusion chamber 527 during the reciprocating lifting process. When the piston ring 520 descends, the extrusion chamber 527 is in a negative pressure environment, and the repair agent in the repair agent chamber 526 is sucked into the extrusion chamber 527 through the one-way valve 521. When the piston ring 520 rises, the one-way valve 521 is closed, and the repair agent in the extrusion chamber 527 is squeezed through the one-way valve 522 into the mixing inner barrel 512, mixed with the soil, and mixed evenly with the stirring component.

[0102] A one-way valve, also known as a check valve or non-return valve, is an automatic control valve that only allows fluid to flow in one direction. Its core function is to prevent the backflow of the medium and ensure the safe operation of the system. Structurally, a one-way valve is mainly composed of a valve body, a valve disc (or valve ball), a valve seat, a spring and a sealing component. Common types include straight-through, right-angle, swing, lift, butterfly and hydraulically controlled types. The straight-through type is directly connected to the pipeline through threads, while the right-angle type provides threaded, plate or flange connection options. The hydraulically controlled one-way valve adds a control oil circuit based on the conical valve core to achieve precise control of bidirectional flow. Special fields such as liquid chromatography systems use precision ceramic components of ruby valve balls and sapphire valve seats, and high-pressure sealing is achieved through nano-level grinding technology.

[0103] The core function of a one-way valve is to block the reverse flow of fluid. It is widely used in hydraulic systems to prevent oil backflow, pneumatic systems to prevent compressed air backflow, water pumps to prevent siphon damage, and air compressor tanks to maintain pressure. Its working principle is based on the synergy of fluid dynamics and mechanics: during forward flow, the medium pressure overcomes the spring resistance or the gravity of the valve disc to open the channel, and during reverse flow, the spring force, the valve disc's own weight and the reverse pressure work together to achieve instantaneous locking. For example, the swing type relies on the fluid to push open the rotating valve disc, and it resets itself after losing pressure; the spring type uses the medium pressure to lift the spring valve disc, and the spring presses down to close the flow channel after the pressure disappears; the hydraulically controlled type achieves bidirectional controllable flow by unlocking the valve disc through external control oil pressure.

[0104] The one-way valve 1 521 and the one-way valve 2 522 of the device are spring-type one-way valves.

[0105] As an optional embodiment, the stirring assembly includes:
