Description

Technical Field

[0001] This utility model specifically relates to a spraying device for remediation agents in heavy metal-contaminated soil. Background Technology

[0002] Soil is a vital component of the human environment and the foundation of human life and production. However, in recent years, due to rapid urban and industrial development, soil pollution has become one of the most prominent environmental problems in my country, especially heavy metal pollution. Heavy metal pollution in soil mainly originates from industrial waste such as mining and metal smelting, as well as the irrational application of wastewater irrigation, pesticides, and fertilizers. Heavy metal pollution not only leads to soil degradation and reduced crop yields and quality, but heavy metals are also absorbed by plants in the soil. Accumulation to a certain limit can cause toxicity to plants and may directly or indirectly harm human health through the food chain.

[0003] Currently, existing soil heavy metal pollution treatment devices generally use rotary rollers to turn the soil after spraying remediation agents. However, this method of turning the soil has a small range and the soil is not thoroughly agitated, making it difficult to quickly and evenly disperse the remediation agents, thus reducing the soil remediation effect. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a spraying device for heavy metal contaminated soil remediation agent.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The soil-turning device includes a mounting frame rotatably mounted on the underside of the vehicle frame, and a driving component for driving the mounting frame to swing and rotate. Several plowshares are arranged at intervals along the direction from the front wheel to the rear wheel on the mounting frame.

[0008] In one embodiment, the spraying device includes a storage box mounted on a vehicle frame and a discharge pipe connected to one side of the storage box. The discharge pipe has two discharge ports, and an adapter is provided at the end of the discharge port of the discharge pipe. The adapter is arc-shaped, and a spray pipe is fitted onto the adapter. The arc-shaped adapter allows the spray pipe to swing relative to the adapter. A plurality of nozzles are spaced apart on one side of the spray pipe, and a transmission mechanism is provided on the vehicle frame to drive the spray pipe to swing back and forth.

[0009] In one embodiment, the transmission mechanism includes a motor mounted on the vehicle frame, a drive wheel on the drive shaft of the motor, a transmission wheel rotatably mounted on the lower side of the vehicle frame, the drive wheel and the transmission wheel being connected by a sprocket and chain drive, an eccentric shaft on one side of each of the drive wheel and the transmission wheel, and movable grooves on each of the two nozzles, with the eccentric shafts movably mounted in the movable grooves in a one-to-one correspondence.

The first hinge seat is rotatably mounted on the vehicle frame, the cylinder is mounted on one side of the first hinge seat, and the second hinge seat is mounted on the drive shaft of the cylinder. The second hinge seat is rotatably connected to the mounting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a soil-turning device to agitate the soil. The driving component in the soil-turning device drives the mounting frame to swing and rotate downwards. As the mounting frame swings, several plowshares on the mounting frame swing relative to the vehicle frame, forming different horizontal depths of soil turning, thereby controlling the soil turning depth of the plowshares. The several plowshares are arranged in a stepped, progressively increasing manner to achieve layered soil turning, reducing soil resistance. Then, in conjunction with a spraying device, a repair agent is sprayed onto the soil after turning, thereby achieving rapid and uniform dispersion of the repair agent to repair the soil.

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0021] like Figures 1-5 The invention relates to a heavy metal contaminated soil remediation agent spraying device, which includes a frame 1, a front wheel and a rear wheel, a soil turning device 2 and a spraying device 3, and a soil turning device 2. The soil turning device 2 includes a mounting frame 21 rotatably mounted on the lower side of the frame 1 and a driving component 22 for driving the mounting frame 21 to swing and rotate. A plurality of plowshares 23 are arranged at intervals along the direction from the front wheel to the rear wheel on the mounting frame 21.

[0022] Specifically, the soil is agitated by a soil-turning device, and the driving component in the soil-turning device drives the mounting frame to swing and flip downwards. As the mounting frame swings, several plows on the mounting frame swing relative to the vehicle frame, forming different horizontal depths of soil turning, thereby controlling the soil turning depth of the plows. The plows are arranged in a stepped, increasing manner to achieve layered soil turning, reducing soil resistance. Then, a spraying device is used to spray a repair agent on the soil after turning, thereby achieving rapid and uniform dispersion of the repair agent to repair the soil.

[0023] Furthermore, the spraying device 3 includes a storage box 31 mounted on the frame 1 and a discharge pipe 32 connected to one side of the storage box 31. The discharge pipe 32 has two discharge ports 33. An adapter 34 is provided at the end of the discharge pipe 32 at its discharge port 33. The adapter 34 is arc-shaped. A spray pipe 35 is fitted on the adapter 34. The arc-shaped adapter 34 allows the spray pipe 35 to swing relative to the adapter 34. A plurality of nozzles 36 are spaced apart on one side of the spray pipe 35. The frame 1 is provided with a transmission mechanism 4 that can drive the spray pipe 35 to swing back and forth.

[0024] Specifically, the nozzle has an arc-shaped cavity, so that when the adapter is arc-shaped and fits into the cavity, the nozzle can swing relative to the adapter. This swing is then driven by a transmission mechanism to increase the spraying area of ​​the nozzle and achieve rapid and uniform dispersion of the remediation agent for soil remediation.

[0025] Furthermore, the transmission mechanism 4 includes a motor 41 mounted on the frame 1, a drive wheel 42 mounted on the drive shaft of the motor 41, a transmission wheel 43 rotatably mounted on the lower side of the frame 1, the drive wheel 42 and the transmission wheel 43 being connected by a sprocket and chain drive, an eccentric shaft 44 being mounted on one side of both the drive wheel 42 and the transmission wheel 43, and a movable groove 45 being mounted on both nozzles 35, with the eccentric shaft 44 being movably mounted in the movable groove 45 in a one-to-one correspondence.

[0026] Specifically, the drive wheel is driven to rotate by a motor, which in turn drives the transmission wheel to rotate via a sprocket and chain drive, thereby achieving synchronous rotation of the drive wheel and the transmission wheel. Then, the eccentric shafts on the drive wheel and the transmission wheel move against the side wall of the nozzle's movable slot, driving the nozzle to reciprocate and swing relative to the adapter.

[0027] Furthermore, the plowshare 23 is detachably connected to the mounting bracket 21 by bolts. This allows the plowshare to be replaced individually if damaged.

[0028] Furthermore, one end of the frame 1 is provided with a towing hole 5 for towing connection, which facilitates the towing and mounting of the tow truck onto the external vehicle body.

[0029] Furthermore, the driving component 22 includes a first hinge seat 24, a cylinder 25, and a second hinge seat 26. The first hinge seat 24 is rotatably mounted on the vehicle frame 1, the cylinder 25 is disposed on one side of the first hinge seat 24, and the second hinge seat 26 is disposed on the drive shaft of the cylinder 25. The second hinge seat 26 is rotatably connected to the mounting bracket 21. Thus, through the combined action of the first hinge seat, the cylinder, and the second hinge seat, the mounting bracket can be tilted and swung upwards or downwards relative to the vehicle body.
