Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a soil remediation and restoration vehicle. Background Technology

[0002] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. It is a technical measure to restore the normal function of contaminated soil.

[0003] Currently, most soil remediation devices used are improvements on rotary tillers. Rotary tillers generally have a frame, rotary blades installed at the bottom of the frame, and a motor to drive the rotary blades to rotate. The improvements are as follows: nozzles and liquid storage tanks are installed at the bottom and top of the frame, respectively. The liquid storage tank is used to supply remediation agents to the nozzles. From the direction of travel of the rotary tiller, the nozzles are located behind the rotary blades. During operation, the rotary blades turn the soil, and the nozzles can spray the remediation agent onto the turned soil, realizing a remediation method of turning and spraying at the same time.

[0004] However, technicians discovered during actual operation that, because the rotation direction of the rotary tiller blades is matched with the direction of travel, the rotation direction of the rotary tiller blades can be adjusted from... Figure 1 To represent, Figure 1 In the diagram, 101 represents the rotary tiller blades, 102 represents the nozzle, 103 represents the liquid supply pipe, and 'a' represents the soil. Therefore, the swirling action of these rotary tiller blades on the soil causes some fine sand and gravel to be splashed diagonally backward. The direction of this splashing can be determined by… Figure 1 The arrows shown indicate that, since the nozzles and liquid supply pipes are located behind the rotary tillers, the splashed sand and gravel often interfere with the spraying operation of the nozzles. In fact, under the high-speed rotation of the rotary tillers, the splashed sand and gravel have high energy and can cause impact damage to the nozzles and liquid supply pipes.

[0005] Therefore, we propose a soil remediation vehicle to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a soil remediation trolley to solve the problems in the prior art. This trolley, through the setting of the barrier component, can not only block and protect the soil splashed by the rotary tiller blades toward the spraying component, but also level the soil that has accumulated and bulged on the ground.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A soil remediation vehicle includes a frame, a spray assembly mounted on the frame, and a rotary tillage assembly mounted on the frame. The nozzles in the spray assembly and the rotary tillage blades in the rotary tillage assembly are located at the bottom of the frame. A barrier is provided at the bottom of the frame between the rotary tillage blades and the nozzles. The barrier is used to block the soil splashed by the rotary tillage blades toward the nozzles.

[0009] As a further embodiment of this utility model: a blocking area is formed between the blocking member and the rotary tillage blade, and the horizontal position of the blocking member at the bottom of the frame is adjustable so as to realize the size of the blocking area is adjustable.

[0010] As a further embodiment of this utility model: the blocking member forms a blocking surface on the side facing the rotary tiller blade, and the angle of the blocking member at the bottom of the frame is adjustable so that the blocking surface has different orientations relative to the rotary tiller blade.

[0011] As a further embodiment of this utility model: the blocking component includes a connecting part and a baffle detachably disposed at the bottom end of the connecting part. The baffle is arranged in an inclined state, and the surface of the baffle facing the rotary tiller blade constitutes the blocking surface. A sliding plate is horizontally slidably installed at the bottom of the frame, and the top end of the connecting part is movably hinged to the sliding plate, so as to realize the distance between the baffle and the rotary tiller blade when the sliding plate slides at the bottom of the frame, and to realize the angle between the blocking surface and the rotary tiller blade when the connecting part rotates on the sliding plate.

[0012] As a further embodiment of this utility model: the connecting part is provided with a threaded hole, and the bottom of the sliding plate is fixedly provided with a semi-circular slide rail that coincides with the rotation trajectory of the threaded hole, and the threaded hole is located in the semi-circular slide rail, so that when the connecting part rotates at a corresponding angle, the position of the connecting part can be locked by relying on the threaded hole and the fastening bolt that matches the threaded hole.

[0013] As a further embodiment of this utility model: the inner side of the semi-circular slide is provided with a scale mark, and the threaded hole is opened at the middle position of the connecting part, so that when the connecting part is arranged in the vertical direction, the threaded hole is located at the middle position of the semi-circular slide and points to the scale mark.

[0014] As a further embodiment of this utility model: the bottom end of the baffle is provided with a notch, and multiple teeth are evenly distributed in parallel at the notch, with the arrangement direction of the multiple teeth being perpendicular to the travel direction of the trolley.

[0015] As a further embodiment of this utility model: the top of the baffle is provided with an insert block, and the bottom of the connecting part is provided with a slot for inserting the insert block and which is adapted to its size. The connecting part is provided with a locking bolt with one end threaded through into the slot cavity, so that when the insert block is located in the slot, the end of the locking bolt abuts against the insert block.

[0016] As a further embodiment of this utility model: the spray assembly includes a liquid storage tank located at the top of the frame, a pump body is installed inside the liquid storage tank, the water outlet of the pump body is connected to a flexible hose extending to the bottom of the frame, the flexible hose is connected to a spray pipe, and the nozzle is installed on the spray pipe.

[0017] As a further embodiment of this utility model: the rotary tillage assembly includes a drive motor mounted on the frame, the drive motor being used to drive the rotary tillage blades to rotate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By integrating the spraying and rotary tillage components at the bottom of the same frame, simultaneous soil tillage and remediation agent spraying are achieved. The barrier located between the rotary tillage blades and the nozzles effectively blocks splashed sand and gravel during high-speed tillage, preventing interference with the spray direction or damage to the nozzles and ensuring even coverage of the remediation agent. Simultaneously, the barrier between the rotary tillage blades and the nozzles also leveles any bulging soil, ensuring soil flatness.

[0020] 2. The adjustable horizontal position of the barrier component allows for dynamic adjustment of the size of the blocking area formed by it and the rotary tillage blades, flexibly adapting to different soil types or rotary tillage depth requirements, thus improving the versatility and adaptability of the remediation trolley.

[0021] 3. The adjustable angle of the baffle allows the baffle surface to adapt to multiple angles according to the rotation direction of the rotary tiller blades and the soil splash trajectory. At the same time, angle adjustment can optimize the force distribution of the baffle, reduce local wear, and extend its service life.

[0022] 4. The design combines a sliding plate and a hinged connection to achieve dual adjustment of the baffle distance and angle. The horizontal sliding of the sliding plate allows for quick adjustment of the distance between the baffle and the rotary tiller blades, adapting to changes in blade speed; the rotational motion of the connection optimizes the blocking effect by changing the baffle tilt angle.

[0023] 5. The design of the threaded hole and the semi-circular slide rail allows for precise locking of the rotation angle of the connection through fastening bolts. This structure combines adjustment flexibility with locking reliability; operation simply requires loosening the bolts, adjusting the angle, and then tightening again, without the need for complex tools. Simultaneously, the semi-circular slide rail limits the adjustment range, preventing mechanical interference or structural damage due to excessive rotation.

[0024] 6. The alignment of the scale markings with the center of the threaded hole allows operators to visually read the tilt angle of the baffle, ensuring adjustment accuracy. When the connecting part is in a vertical position, the threaded hole is located in the middle of the slide, at which point the baffle is in its default protective position, i.e., the zero-position, facilitating quick reset or standardized operation.

[0025] 7. The toothed design at the bottom of the baffle enhances the leveling function of the barrier. During operation, the gaps between the teeth allow some fine soil to pass through, preventing soil accumulation at the bottom of the baffle. Simultaneously, multiple teeth disperse the concentrated impact force to different areas, reducing single-point wear. Furthermore, the teeth are arranged perpendicular to the direction of travel, allowing for lateral guidance of splashed material and preventing secondary splashing of sand and gravel that comes into contact with the teeth from interfering with the spraying operation.

[0026] 8. The insertion and locking bolts of the insert block and slot enable quick installation and removal of the baffle. When replacing the baffle, simply loosen the bolts to remove the old baffle and insert the new part, which is quick. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] like Figures 2-5 As shown, a soil remediation trolley includes a frame 1 that forms the overall structure of the trolley. The bottom of the frame 1 is equipped with wheels, the type of which can be set according to the type of soil a being traversed. A handrail is provided on one side of the frame 1 to facilitate operation by construction personnel. A spraying component 2 and a rotary tillage component 3 are provided on the frame 1. From the perspective of the trolley's direction of travel, the spraying component 2 is located behind the rotary tillage component 3. After the rotary tillage component 3 turns over the soil a, the spraying component 2 can spray the turned soil a with a remediation agent.

[0043] like Figure 2 As shown, the spraying assembly 2 includes a liquid storage tank 202 located at the top of the frame 1. A cap 2021 on the top of the tank allows the inlet to be opened, allowing the remedial agent to be added to the tank. A pump body is installed inside the tank. The pump body's outlet is connected to a flexible hose 203 extending to the bottom of the frame 1. The flexible hose 203 is connected to a spray pipe 204, which has multiple nozzles 201 positioned at different angles towards the soil surface a. The rotary tillage assembly 3 includes rotary tillage blades 301 located at the bottom of the frame 1 and a drive motor 302 located on the side of the frame 1. The output shaft of the drive motor 302 is coaxially connected to the rotary tillage blades 301. An energy storage assembly 7 is also located at the top of the frame 1. The energy storage assembly 7 includes a battery, which powers the drive motor 302 and the pump body.

[0044] like Figures 2-3 As shown, in order to prevent the rotary tiller 3 from splashing sand and gravel onto the spray assembly 2 when it acts on soil a, which would cause the spray direction of the spray assembly 2 to be interfered with or damaged by impact, this application provides a barrier 4 at the bottom of the frame 1. The barrier 4 is located between the spray assembly 2 and the rotary tiller 3 to deal with the sand and gravel splashed from the rotary tiller 3 toward the spray assembly 2, thus ensuring the normal operation of the spray assembly 2.

[0045] Specifically, the design for the barrier 4 at the bottom of the frame 1 is as follows:

[0046] 1) The barrier 4 is set to be adjustable in a horizontal position at the bottom of the frame 1. Based on the barrier 4 forming a blocking area between the rotary tillage blades 301, the horizontal adjustment of the position of the barrier 4 can change the size of the blocking area to adapt to different blade speeds and soil conditions. For example, when rotating at high speed, the barrier 4 may need to be closer to the blades to block splashes earlier.

[0047] 2) The obstruction element 4 is configured to have an adjustable angle at the bottom of the frame 1. Based on the obstruction surface formed by the obstruction element 4 facing the rotary tiller blades 301, adjusting the angle of the obstruction element 4 itself can change the angle of the obstruction surface relative to the rotary tiller blades 301, thus better guiding sand and gravel to the side or below. According to fluid mechanics, preferably, the tilt angle of the obstruction element 4 after adjustment is between 45 and 60 degrees. This effectively blocks sand and gravel while reducing resistance during the trolley's movement.

[0048] 3) The barrier 4 is set to be adjustable in both horizontal position and angle at the bottom of the frame 1. This combination adjustment design allows the barrier 4 to be adjusted to a suitable position based on factors such as soil a adjustment and rotary tillage blade 301 speed.

[0049] The following is an explanation of the design of the third type of barrier element 4 mentioned above:

[0050] like Figure 4 As shown, the barrier 4 includes a connecting part 401 and a baffle 402 disposed at the bottom end of the connecting part 401. In the initial state, the connecting part 401 is arranged vertically, and the baffle 402 is arranged at an angle. The surface of the baffle 402 facing the rotary tiller blade 301 forms the aforementioned blocking surface. A sliding groove is provided at the bottom of the frame 1, and a sliding plate 403 is horizontally slidably installed in the sliding groove. After the sliding plate 403 slides to a designated position, its position can be locked using screws or the like. The top of the connecting part 401 is movably hinged to the slide plate 403. A semi-circular slide rail 6 is fixedly provided on the slide plate 403. A threaded hole 5 is provided on the connecting part 401. The threaded hole 5 can move with the rotation of the connecting part 401. A semi-circular slide rail 6 is fixedly provided at the bottom of the slide plate 403. The semi-circular slide rail 6 and the movement trajectory of the threaded hole 5 are coincident. The threaded hole 5 is located inside the semi-circular slide rail 6. When the connecting part 401 is adjusted at a specified angle with its hinge point, the threaded hole 5 will move to the position inside the semi-circular slide rail 6. Then, the position of the connecting part 401 on the semi-circular slide rail 6 is locked by the threaded hole 5 and the fastening bolt that is threaded to the threaded hole 5. That is, the position of the baffle 402 is locked.

[0051] For example Figure 4As shown, to determine the angle of rotation of the baffle 402 each time, a scale mark 601 is provided on the inner side of the semi-annular slide 6. Based on this design, the threaded hole 5 is located at the middle position of the connecting part 401. Simultaneously, when the connecting part 401 is arranged vertically, the threaded hole 5 will be located at the middle position of the semi-annular slide 6 and point towards the scale mark 601. Preferably, when the threaded hole 5 is located at the middle position of the semi-annular slide 6, the threaded hole 5 is positioned to point towards the middle position of the scale mark 601, and at this time, the middle position of the scale mark 601 can be set to zero.

[0052] Because the baffle 402 is prone to damage and deformation during long-term use, this application provides a detachable connection between the connecting part 401 and the baffle 402 for easy assembly and disassembly at the bottom of the frame 1. This detachable connection can be any method available in the prior art, such as snap-fit ​​or fastening. Figure 4 As shown, this paper proposes the following detachable connection structure: a plug 4022 is provided at the top of the baffle 402, and a slot 4011 with a size that is adapted to the plug 4022 is provided at the bottom of the connecting part 401. A locking bolt 4012 with one end threaded through into the slot 4011 is provided on the connecting part 401 so that when the plug 4022 is located in the slot 4011, the end of the locking bolt 4012 abuts against the plug 4022.

[0053] like Figure 5 As shown, during the process of the baffle 402 blocking the sand and gravel splashed by the rotary tiller blades 301, in order to prevent the sand and gravel from accumulating and bulging on the ground soil a, this application has a notch at the bottom of the baffle 402, and multiple teeth 4021 are evenly arranged in parallel at the notch. The arrangement direction of the multiple teeth 4021 is perpendicular to the traveling direction of the trolley. Therefore, during the travel of the trolley, the multiple teeth 4021 will flatten the accumulated sand and gravel, so that the ground soil a remains flat.

[0054] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
