DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 In this embodiment, a soil crushing, mixing and dosing equipment includes a box body 1, a feed hopper 2 is installed on the top of the box body 1, a support leg 3 is fixedly installed on the bottom of the box body 1, a transmission component 4 is provided on the left side of the box body 1, a crushing and stirring roller 5 is provided inside the box body 1, a spray pipe 6 is provided inside the box body 1, a dosing component 7 connected to the spray pipe 6 is provided on the right side of the box body 1, and an anti-blocking component 8 is provided at the discharge port of the box body 1.

[0023] The soil is poured into the feed hopper 2 of the box body 1, and the transmission component 4 drives the crushing and stirring roller 5 to crush the soil. At the same time, the dosing component 7 can be used to pressurize the medicine into the spray pipe 6, and the soil is sprayed by the spray pipe 6. The chemical solution is sprayed into the soil, which can be a chemical oxidizing agent, a heavy metal stabilizing agent, a leaching agent, etc. The crushing process allows the agent to be better mixed with the contaminated soil, thereby realizing the integrated function of crushing and spraying.

[0024] The dosing assembly 7 includes a dosing box 701 fixedly installed on the right side of the box body 1. The top of the dosing box 701 is connected to a drug inlet pipe, and the top of the drug inlet pipe is connected to a funnel. A pump body 702 is fixedly installed on the inner wall of the dosing box 701. The liquid inlet of the pump body 702 is connected to a liquid inlet pipe 703, and the liquid outlet of the pump body 702 is connected to a liquid outlet pipe 704, and the liquid outlet pipe 704 is connected to the spray pipe 6.

[0025] The spray pipe 6 is U-shaped and fixedly connected to the inner wall of the box 1. A plurality of atomizing nozzles are connected to the side of the spray pipe 6 facing the inner cavity of the box 1. The spray pipe 6 and the atomizing nozzles can form a water mist belt of the chemical, which is thoroughly mixed with the soil passing through. Due to the effect of the water mist of the chemical, the process can minimize the generation of dust and ensure green construction.

[0026] The transmission assembly 4 includes a working box 401 fixedly installed on the left side of the box body 1, and a transmission gear 402 fixedly connected to the outer surface of the crushing and stirring roller 5 is provided inside the working box 401. A motor 403 is fixedly installed on the outer surface of the working box 401, and the output shaft of the motor 403 is fixedly connected to the roller shaft of the crushing and stirring roller 5.

[0027] The crushing and stirring rollers 5 are divided into two groups, each containing four rollers. Each crushing and stirring roller 5 in a group is connected to a transmission gear 402, and the transmission gears 402 in the same group mesh with each other. The teeth of the crushing and stirring roller 5 at the top are spaced farther apart than those at the bottom. The motor 403 drives each crushing and stirring roller 5 to rotate. Because the transmission gears 402 in the same group mesh with each other, two adjacent crushing and stirring rollers 5 rotate relative to each other, crushing and stirring the soil.

[0028] The crushing and stirring roller 5 at the top first crushes the soil, breaking the contaminated soil into blocks of ≤20mm, and then the crushed soil is crushed by the crushing and stirring roller 5 at the bottom to break the contaminated soil into blocks of ≤10mm. The crushing process also has a stirring function, and the crushing process allows the agent to be better mixed with the contaminated soil. After two-stage crushing, the soil becomes fine particles, which can fully contact with the agent sprayed by the dosing system, promote the reaction of the agent, and the subsequent soil is tested and discharged after corresponding maintenance.

[0029] The anti-blocking component 8 includes an electric push rod 801 fixedly installed on the bottom of the box body 1, and a connecting rod 802 is fixedly installed on the output shaft of the electric push rod 801. A push block 803 is installed on the top of the connecting rod 802 and located at the discharge port of the box body 1. The cross-section of the push block 803 is an inverted "V" shape, and a support rod is fixedly installed on the bottom of the push block 803, and the bottom end of the support rod is fixedly connected to the connecting rod 802.

[0030] When the crushed soil is blocked at the discharge port of the box body 1, the electric push rod 801 can be used to drive the push block 803 on the connecting rod 802 to move up and down, which can effectively clear the soil at the discharge port and prevent the discharge port from being blocked.

[0031] The working principle of the above embodiment is:

[0032] The soil is poured into the feed hopper 2 of the box body 1, and the motor 403 drives a crushing and stirring roller 5 to rotate. Since the transmission gears 402 in the same group are engaged with each other, the two adjacent crushing and stirring rollers 5 can rotate relative to each other to crush and stir the soil. While the crushing and stirring rollers 5 crush the soil, the pump body 702 can be used to pressurize the medicine into the spray pipe 6, and the spray pipe 6 is used to spray the soil. The spray pipe 6 and the atomizing nozzle cooperate to form a medicine water mist belt, so that the medicine is fully mixed with the soil passing through. In addition, due to the effect of the water mist medicine, the medicine solution sprayed into the soil can be a chemical oxidizing agent, a heavy metal stabilizing agent, a leaching agent, etc. The crushing process allows the medicine to be better mixed with the contaminated soil, thereby realizing the integrated effect of crushing and spraying.
