[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

[0035] Embodiment 1:

[0036] like Figures 1 to 5 As shown, in the first aspect, embodiment 1 of the present application provides a crushing and mixing mechanism, including: a crushing component 10 and a feeding component 20, the crushing component 10 includes a force-applying structure 11, a connecting rod 12 and a crushing end head 13 arranged in sequence, the cross-sectional area of ​​the crushing end head 13 gradually increases along the direction away from the connecting rod 12 to the direction close to the connecting rod 12, and the crushing end head 13 can crush and mix soil and repair agents; the feeding component 20 includes a fixedly connected material box 21, a feeding pipe 22 and a trigger structure 23, the material box 21 is fixedly connected to the connecting rod 12, and the trigger structure 23 controls the opening and closing of the discharge port 221 of the feeding pipe 22.

[0037] The crushing end 13 can be used to initially dig out the soil so that it is easy to deform and mix. The material discharging component 20 can directly carry out material discharging and release the repair agent. The crushing end 13 further mixes the material so that the repair agent can be fully mixed with the soil, which can effectively improve the progress of soil repair and even the degree of soil repair. Its cross-sectional area gradually increases. When crushing the soil and the repair agent, it can squeeze the soil or the repair agent to make the mixture more uniform and achieve a better soil repair effect.

[0038] It should be noted that the discharge pipe 22 is configured as a channel with multiple turning positions. Such a configuration can utilize the height difference to control the order of discharge, is easier to control, and does not cause the repair agent to slip all at once, making it more convenient and reliable to use.

[0039] like Figures 1 to 5 As shown, the projection of the discharge port 221 in a direction perpendicular to the crushing end 13 is located inside the crushing end 13, and the opening direction of the discharge port 221 is set away from the crushing end 13. This setting allows the repair agent to be directly away from the crushing end 13 when released. The user is located on the side of the crushing end 13 away from the discharge port 221, which makes it easy to observe the amount of repair agent released, provides a field of view, and is more convenient to use.

[0040] It should be noted that, compared with the existing solutions, for example, the patent document with announcement number CN215143349U discloses a soil pollution remediation agent landfill device, including a mobile platform, a liquid medicine tank is fixedly connected to the right side of the top of the mobile platform, the front and back sides of the top of the mobile platform are fixedly connected to columns, the outer sides of the two columns are slidably connected to sliding connectors, a cross plate is fixedly connected between the two sliding connectors, an oil cylinder is hinged between the left side of the top of the mobile platform and the left side of the bottom of the cross plate, a water pump is fixedly installed inside the liquid medicine tank, and a drug landfill device is fixedly installed on the top of the cross plate. That is, although the existing solution has the advantages of mechanized operation, time saving, labor saving and efficiency improvement, it is large in size and inconvenient to move in the area to be repaired, and cannot be used conveniently.

[0041] Reference Figures 1 to 3 In the technical solution of the first embodiment, the material box 21 is fixedly mounted on the connecting rod 12 by the material unloading assembly 20 through the connecting sleeve 212, and the material box 21 is connected to the unloading pipe 22 under the inclined bottom box body 211. When the soil remediation agent is landfilled, the connecting rod 12 is driven by the force structure 11 to drive the crushing end 13 to crush the soil, so that the soil is dispersed and easy to mix, and then the unloading pipe 22 is triggered by the structure 23 to release the remediation agent, and then the soil and the remediation agent are mixed, so that the soil crushing, unloading, mixing and other operations are realized, and the operation is more convenient and efficient. At the same time, the overall structure is compact, small in size, easy to carry, highly convenient, and applicable to a wide range of environments, and does not require a lot of manpower and material resources to carry the equipment.

[0042] like Figure 3 As shown, in the technical solution of the first embodiment, the crushing end 13 is a sheet-like structure, and the thickness of the crushing end 13 gradually increases from the direction away from the connecting rod 12 to the direction close to the connecting rod 12. The sheet-like structure can reduce the area of ​​the first region in contact with the soil, achieve a better crushing effect, and at the same time realize the action of turning the soil, digging out part of the crushed soil, and forming a receiving groove 40.

[0043] The thickness of the crushing end 13 gradually increases from the direction away from the connecting rod 12 to the direction close to the connecting rod 12. On the one hand, such a setting can increase the structural strength of the crushing end 13 and increase its service life. On the other hand, it can form a plane with a certain curvature. When crushing the soil and the repair agent, it can drive the soil or the repair agent to be squeezed to both sides along the arc surface, thereby achieving separation.

[0044] like Figure 2 As shown, in the technical solution of the first embodiment, the width of the crushing end 13 gradually increases along the direction away from the connecting rod 12 to the direction close to the connecting rod 12. That is, in the main viewing direction of the crushing end 13, the width of the end away from the connecting rod 12 gradually increases along the direction close to the connecting rod 12. Such a setting has a smaller first contact area with the crushed soil or repair agent during crushing soil or repair agent, and a greater pressure is generated under the same force, thereby achieving a better crushing effect.

[0045] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the crushing assembly 10 includes a foot plate 14, which is fixedly connected to the connecting rod 12 and is located between the force-applying structure 11 and the crushing end 13. The force-applying structure 11 is a handle arranged horizontally, which is convenient for holding and applying force with the palm.

[0046] The foot pedal 14 is arranged on one side of the connecting rod 12 close to the crushing end 13. When crushing, the foot pedal 14 can be stepped on by the foot to transfer the force to the connecting rod 12, thereby providing a stronger crushing force and making the crushing action better.

[0047] There are two foot plates 14, and the surface of the foot plates is provided with a non-slip friction surface, and the friction surface can be in a shape of a rhombus, an arc, etc. to increase the friction force. The foot plates 14 are arranged in a long strip shape, and their extension direction is parallel to the extension direction of the force-applying structure 11. Such an arrangement can keep the driving force direction of the connecting rod 12 consistent, thereby achieving driving force superposition and increasing the crushing effect, and at the same time will not affect the posture and vision of the user.

[0048] like Figure 4 As shown, in the technical solution of the first embodiment, the feed pipe 22 is provided with a limited slot 222, and the trigger structure 23 includes a sliding block 231, which is slidably located in the limited slot 222, and the sliding block 231 is adapted to the discharge port 221. The matching arrangement of the limited slot 222 and the sliding block 231 realizes the close matching of the position of the discharge port 221, the opening direction is fixed, and the circumferential degree of freedom of the sliding block 231 can be limited at the same time, the structure is compact, the function is stable, and the sliding block 231 can close the discharge port 221 under the action of gravity, which can reduce the influence of the discharge port 221 in the process of soil crushing, and prevent the repair agent from falling into the soil in advance, which affects the subsequent mixing effect.

[0049] It should be noted that, further, the width of the sliding block 231 matches the width of the limiting slide groove 222 and the width of the discharge port 221. Such a structure is more compact, easy to assemble, and has a better matching effect during use.

[0050] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the material box 21 includes a sloping bottom box body 211 and a connecting sleeve 212 fixedly installed on the back of the sloping bottom box body 211, the connecting sleeve 212 is sleeved on the connecting rod 12, and a feeding port is provided at the upper end of the sloping bottom box body 211, and a screw cap 213 is threadedly installed on the feeding port. After the screw cap 213 is opened, it is convenient to add the granular repair agent into the material box 21 through the feeding port, and the sloping bottom design of the sloping bottom box body 211 makes it easier for the granular repair agent to fall.

[0051] The specific structure of the inclined bottom box 211 is that an inclined surface is provided on the side of the box away from the force-applying structure 11, so that the cross-sectional area of ​​the inclined bottom box 211 gradually decreases in the downward direction away from the force-applying structure 11, which facilitates the accumulation and sliding of the granular repair agent.

[0052] like Figures 1 to 3As shown, in the technical solution of the first embodiment, the feed pipe 22 is a square tube structure. The square tube structure is convenient for assembly and is also convenient for installation of other components on the square tube.

[0053] like Figures 1 to 5 As shown, in the technical solution of the first embodiment, the trigger structure 23 includes a connected connecting piece 232 and a driving end 233, the connecting piece 232 is connected to the sliding block 231, and the driving end 233 is located on the side of the material box 21 away from the feeding pipe 22. The arrangement of the driving end 233 and the connecting piece 232 realizes the driving of the sliding block 231, which can facilitate the user to maintain a relatively comfortable posture when standing or after completing the soil crushing so that the sliding block 231 slides to open the discharge port 221.

[0054] It should be noted that the driving end 233 is located on the side of the material box 21 away from the discharge pipe 22. This refers to the relative position between the driving end 233 and the material box 21, not that there is a necessary connection relationship between the driving end 233 and the material box 21. When the driving end 233 is located in this position, it can ensure that the user can open the discharge port 221 and release the granular repair agent without squatting.

[0055] like Figures 1 to 5 As shown, in the technical solution of the first embodiment, the trigger structure 23 includes a reset member 234, which is fixedly arranged and applies a thrust to the sliding block 231. The reset member 234 is arranged to keep the sliding block 231 always covering the discharge port 221, thereby preventing the entire crushing and mixing mechanism from reciprocating during the crushing process, causing the sliding block 231 to be subjected to upward inertia, thereby causing the discharge port 221 to open.

[0056] It should be noted that the reset member 234 can specifically be a component with a certain elasticity, such as a spring, a torsion spring, a leaf spring, silicone, etc., or a structure that can continuously apply a downward force, such as a non-electrically driven cylinder, a hydraulic cylinder, etc., or a structure that can form a reset self-locking, such as a ratchet and a rack that cooperate with each other.

[0057] like Figures 1 to 5As shown, in the technical solution of the first embodiment, the trigger structure 23 includes a fixed seat 235 fixedly arranged on the feeding tube 22, a connecting rod 236 is arranged on the side of the connecting member 232 away from the driving end 233, the connecting rod 236 passes through the fixed seat 235 and is fixedly connected to the sliding block 231, and the reset member 234 is a spring, one end of which is fixed on the fixed seat 235, and the other end is against the sliding block 231. The reset member 234 is a spring that can continuously apply a thrust to the sliding block 231 through the fixed seat 235, thereby locking the sliding block 231 and preventing the sliding block 231 from sliding out of the limiting slide groove 222. It should be noted that when the sliding block 231 needs to be opened, a pulling force is applied to the connecting member 232, so that the sliding block 231 pushes the reset member 234 and converts the force into elastic potential energy. The reset member 234 stores the elastic potential energy after deformation. When the pulling force applied to the connecting member 232 disappears, the elastic potential energy is released and converted into thrust, thereby resetting the sliding block 231 to a state of covering the discharge port 221.

[0058] Specifically, Figure 4 As shown, in the technical solution of embodiment 1, the setting of the fixed seat 235 is used to form the installation of the connecting rod 236. Specifically, the fixed seat 235 is fixed on the side of the discharge pipe 22 away from the crushing end 13, and a circular hole is formed above it. The axial direction of the circular hole is parallel to the side wall of the discharge pipe 22. The connecting rod 236 passes through the circular hole to form a mutual circumferential freedom restriction, that is, the connecting rod 236 can only slide along its axial direction, thereby achieving a higher precision sliding direction restriction.

[0059] Preferably, the connecting rod 236 is inserted into the spring, that is, inserted into the reset member 234. Such a setting structure is more compact. At the same time, the assembly of the reset member 234 and the connecting rod 236 cooperates with each other. The circumferential degree of freedom of the connecting rod 236 is more strictly restricted. At the same time, it plays a guiding role for the spring. When the spring is deformed, the circumferential degree of freedom of the spring can be limited, that is, there is no risk of circumferential deformation of the spring, which is beneficial to improving the service life of the trigger structure 23.

[0060] It should be noted that in the technical solution of embodiment one, the fixed seat 235 is welded to the discharge pipe 22 by welding. In order to adapt to the reciprocal movement of the reset member 234, a reciprocal seat is welded on the side of the sliding block 231 facing the connecting rod 236, and the reciprocal seat can meet the installation requirements of the spring.

[0061] The application of the technical solution of the first embodiment has the following beneficial effects:

[0062] The material box 21 is installed at the upper part of the connecting rod 12, and a sliding block 231 for blocking the discharge port 221 is set on the discharge pipe 22 at the lower end of the material box 21. When the soil remediation agent is buried, the crushing end 13 of the crushing assembly 10 is reciprocatedly inserted into the soil for crushing, and a part of the soil is excavated forward to form a receiving groove 40. The connecting rod 236 is lifted by the trigger structure 23 to open the discharge port 221, and the granular repair agent falls into the receiving groove 40 along the discharge pipe 22. The crushing end 13 is used to perform reciprocating crushing operations to fully mix the repair agent and the soil. Then the crushing end 13 is pulled out, and the excavated part of the soil is backfilled to bury the mixed soil, thereby realizing operations such as digging pits, discharging materials, and burying. The operation is more convenient and efficient. At the same time, it is small in size, easy to carry, and highly convenient.

[0063] Embodiment 2:

[0064] like Figure 6 to Figure 7 As shown, based on the first embodiment, the present application proposes a technical solution of the second embodiment, which is as follows:

[0065] The second embodiment provides a crushing and mixing mechanism, wherein the connecting member 232 is a traction rope, the driving end 233 is a take-up wheel, and the take-up wheel is fixedly arranged on the surface of the material box 21. The arrangement of the take-up wheel can directly lift the connecting rod 236 in a rolling manner, thereby realizing the opening and closing of the discharge port 221. The take-up wheel is fixed on the surface of the material box 21, which is convenient for the user to operate, and can be opened to collect and release the repair agent when the crushing assembly 10 stops working.

[0066] Furthermore, the take-up wheel is fixed to the surface of the material box 21 through a seat body, and a ratchet structure is arranged between the take-up wheel and the seat body. The position and state of the take-up wheel can be controlled by the ratchet wheel. When the discharge port 221 does not need to be opened, self-locking can be formed, and accidental rolling will not occur, causing the discharge port 221 to open, and the controllability is stronger.

[0067] Furthermore, if Figure 6 As shown, in the technical solution of Example 2, a pulley group is further arranged between the take-up wheel and the connecting rod 236, and the connecting member 232 changes its guiding direction through the pulley group. Such an arrangement, on the one hand, cooperates with the traction rope to change the direction of the force, and on the other hand, reduces the sliding friction at the reversing position of the traction rope to rolling friction, which is beneficial to increasing the service life of the traction rope.

[0068] The pulley block specifically comprises a connecting arm and a pulley arranged on the connecting arm. One end of the connecting arm is fixed on the side of the material box 21 facing the connecting rod 12, and the pulley is rotatably arranged on the other end of the connecting arm. The diameter of the pulley is larger than the cross-sectional size of the connecting arm. Such an arrangement avoids friction between the traction rope and the connecting arm after installation, while being able to meet the fixed installation position of the connecting arm.

[0069] The connecting arm and the side of the material box 21 facing the connecting rod 12 can be set vertically or in an oblique upward direction, and can be fixed by welding to ensure that the traction rope will not rub against the edge of the material box 21 after installation.

[0070] Embodiment three:

[0071] like Figures 8 to 9 As shown, based on the first embodiment, the present application proposes a technical solution of the second embodiment, which is as follows:

[0072] The third embodiment provides a crushing and mixing mechanism, wherein the connecting member 232 is a traction rope, the driving end 233 is a take-up wheel, and the take-up wheel is fixedly arranged on the force-applying structure 11 of the material box 21 .

[0073] The setting of the take-up wheel can directly lift the connecting rod 236 in a rolling manner, thereby realizing the opening and closing of the discharge port 221. The take-up wheel is fixedly set on the force structure 11 of the material box 21, which is convenient for the user to operate. That is, the user can roll the take-up wheel when holding the force structure 11, thereby pulling open the discharge port 221 and completing the delivery of the repair agent.

[0074] Furthermore, the take-up wheel can be directly set in the form of a ratchet, and the position and state of the take-up wheel can be controlled by the ratchet. When the discharge port 221 does not need to be opened, it can be self-locking, and there will be no accidental rolling, which will cause the discharge port 221 to be opened, and the controllability is stronger. The user can open the discharge port 221 by twisting the take-up wheel, or the take-up wheel can be integrated at one end of the force-applying structure 11 and rotated in a manner similar to the throttle of a motorcycle handle.

[0075] The take-up wheel can also be directly connected to the force-applying structure 11 by means of a torsion spring. Such a setting can realize the retraction of the take-up wheel, thereby satisfying the resetting of the take-up wheel. In combination with the resetting member 234, the opening and closing of the discharge port 221 can be better controlled.

[0076] Furthermore, if Figure 8 As shown, in the technical solution of Example 3, a pulley group is further arranged between the take-up wheel and the connecting rod 236, and the connecting member 232 changes its guiding direction through the pulley group. Such an arrangement, on the one hand, cooperates with the traction rope to change the direction of the force, and on the other hand, reduces the sliding friction at the reversing position of the traction rope to rolling friction, which is beneficial to increasing the service life of the traction rope.

[0077] The pulley block specifically comprises a connecting arm and a pulley arranged on the connecting arm. One end of the connecting arm is fixed on the side of the material box 21 facing the connecting rod 12, and the pulley is rotatably arranged on the other end of the connecting arm. The diameter of the pulley is larger than the cross-sectional size of the connecting arm. Such an arrangement avoids friction between the traction rope and the connecting arm after installation, while being able to meet the fixed installation position of the connecting arm.

[0078] The connecting arm and the side of the material box 21 facing the connecting rod 12 can be set vertically or in an oblique upward direction, and can be fixed by welding to ensure that the traction rope will not rub against the edge of the material box 21 after installation.

[0079] Embodiment 4:

[0080] like Figures 10 to 12 As shown, based on the first embodiment, the present application proposes a technical solution of the fourth embodiment, which is as follows:

[0081] Embodiment 4 provides a crushing and mixing mechanism, wherein the connecting member 232 includes a rotating lever 237 and a connecting long rod 238, and the driving end 233 includes a pressing link 239. The rotating lever 237 is connected to the connecting member 232 and is rotatably arranged on the connecting rod 12. The connecting long rod 238 is rotatably connected to the rotating lever 237 and the pressing link 239 respectively, and the pressing link 239 is arranged on the surface of the material box 21 or the force structure 11.

[0082] By rotating the lever 237, the connecting rod 236 can be lifted according to the lever principle. This arrangement has a more compact structure, convenient transmission, a more convenient pressing method, and a better user experience.

[0083] like Figures 10 to 12 As shown, in the technical scheme of embodiment 4, the rotating lever 237 is rotatably connected to the pivot shaft on the connecting rod 12, and its rotation realizes the effect of the lever. One end of the rotating lever 237 is in the shape of a clamp, which clamps the end of the connecting rod 236. A blocking block is provided at the end of the connecting rod 236, and the connecting rod 236 is limited by the blocking block. Such a setting makes the connecting rod 236 and the rotating lever 237 have surface contact, and the surfaces are limited when they are against each other. It is not a fixed connection, and the rotation of the lever will not affect the spatial position relationship between the two, and no interference will occur.

[0084] like Figures 10 to 12 As shown, in the technical solution of the fourth embodiment, the pressing link 239 is rotatably connected to the seat on the top surface of the material box 21 to facilitate the user's operation and is arranged near the rotary cover 213.

[0085] In an optional embodiment, the pressing link 239 can be integrated into the force-applying structure 11, which is more convenient for users to operate. The pressing link 239 can be directly set in the form of a ratchet, and the position and state of the pressing link 239 can be controlled by the ratchet. When the discharge port 221 does not need to be opened, self-locking can be formed, and accidental rolling will not occur, causing the discharge port 221 to open, and the controllability is stronger.

[0086] The pressing link 239 can also be directly connected to the force-applying structure 11 by means of a torsion spring. Such a setting can achieve the maintenance of the initial state of the pressing link 239 and at the same time satisfy the reset of the pressing link 239. In combination with the reset member 234, the opening and closing of the discharge port 221 can be better controlled.

[0087] In a second aspect, the present application provides a crushing and mixing device, which includes a crushing and mixing mechanism as in any of the above embodiments. Using the crushing and mixing mechanism as in any of the above embodiments makes soil remediation more convenient and reliable, and is not limited by the location and shape of the land, which is convenient for users to use.

[0088] In a third aspect, the present application provides a soil remediation agent landfill method, using a crushing and mixing mechanism as in any of the above embodiments, the soil remediation agent landfill method includes:

[0089] Step 1: The force structure 11 reciprocates downward to crush the crushing end 13 to crush the soil; the soil is crushed to obtain easily mixed soil and soil for burial. The force direction and magnitude of the force structure 11 can be changed during the reciprocating downward pressure, thereby making the soil more crushed.

[0090] Step 2: dig out part of the soil through the crushing end 13 to form a receiving groove 40; dig out the soil reserved for burial, leaving the soil that needs to be mixed.

[0091] Step three: drive the trigger structure 23 to open the discharge port 221 and release the repair agent into the receiving groove 40; specifically, the trigger structure 23 causes the sliding block 231 to slide upward along the limiting slide groove 222, thereby opening the discharge port 221, and the repair agent slides into the receiving groove 40.

[0092] Step 4: The crushing end 13 is reciprocally pressed down by the force-applying structure 11 to crush the repair agent in the receiving tank 40, obtain the repair agent particles, and mix the soil in the receiving tank 40 with the repair agent particles; the soil and the repair agent particles are fully mixed to make the soil and the repair agent more bonded.

[0093] Step 5: Backfill part of the excavated soil to complete the landfill of the repair agent.

[0094] By applying the method in the above embodiment, multiple functions such as excavation, crushing, mixing and landfilling can be achieved, the efficiency and quality of soil remediation are improved, and it is not limited by the location and shape of the land, which is convenient for users to use.
