DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] As attached Figure 1 To Attachment Figure 4 As shown:

[0022] Embodiment 1: The utility model provides a drug injection and screening device based on contaminated soil remediation, including a main body 1, including an ALLU bucket 101, a soil crushing gear 102 arranged in the ALLU bucket 101, a spraying pipe 103 arranged at the front end of the ALLU bucket 101, and two feeding pipes 105 arranged on the spraying pipe 103; a control mechanism 2, including a switching component 201 arranged between the feeding pipe 105 and the ALLU bucket 101, and a connecting component 202 arranged on the switching component 201.

[0023] Specifically, the switching assembly 201 includes a valve seat 2015 disposed on the feed pipe 105 , a valve block 2014 disposed in the valve seat 2015 , a movable seat 2012 disposed between the valve blocks 2014 , and an electric push rod 2011 disposed between the movable seat 2012 and the ALLU bucket 101 .

[0024] Furthermore, a limit guide rail 2013 is provided on the ALLU bucket 101 , and the limit guide rail 2013 is slidably connected to the movable seat 2012 .

[0025] As can be seen from the above, when in use, the ALLU bucket 101 is installed on a large machine such as an excavator or a loader, and then the soil is excavated using the ALLU bucket 101. When the front end of the ALLU bucket 101 is facing backward, the soil will fall onto the soil crushing gear 102 under the action of its own weight, and the soil will be crushed by the soil crushing gear 102. The crushed soil will fall through the front end of the ALLU bucket 101, completing the soil screening work;

[0026] The spraying pipe 103 is connected to the external agent pipeline and the curing water pipeline respectively through the two feeding pipes 105. The valve block 2014 is initially in the open state, so that the agent and the curing water can be transported to the spraying pipe 103 for spraying. The electric push rod 2011 is started. Under the limit guidance of the limit guide rail 2013, the electric push rod 2011 drives the movable seat 2012 to connect the two valve blocks 2014 to move synchronously, so that one group of valve blocks 2014 and the valve seat 2015 are closed, and the other group of valve blocks 2014 and the valve seat 2015 are opened, and vice versa, so that a single agent pipeline or a single curing water pipeline is connected to the spraying pipe 103, so that the agent can be sprayed for soil remediation after soil screening, or the curing water can be sprayed to adjust the soil moisture content and the amount of agent added, so as to control dust during the screening process.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the connecting component 202 includes a bidirectional motor 2021 arranged on the movable seat 2012, threaded rods 2022 arranged at both ends of the bidirectional motor 2021, and an electric control valve 2023 arranged on the spray pipe 103.

[0028] Specifically, the threaded rod 2022 is threadedly connected to the valve block 2014 .

[0029] Furthermore, a plurality of spray ports 104 are provided on the spray pipe 103 .

[0030] As can be seen from the above, the two valve blocks 2014 can be opened by the electric push rod 2011 as needed, and then the spray pipe 103 can be disconnected from the middle by the electric control valve 2023 to form two spray pipes 103. At this time, the medicine and water will be respectively transported to the two spray pipes 103 and sprayed out through the spray port 104, so as to carry out spraying repair and water spraying maintenance work while screening the soil, greatly improving work efficiency. After the work is completed, the two-way motor 2021 is started, and the two-way motor 2021 will drive the two threaded rods 2022 to rotate. The threads of the two threaded rods 2022 are in opposite directions, thereby driving the two valve blocks 2014 to separate or move synchronously, thereby controlling the opening and closing of the two valve seats 2015 at the same time, and controlling the synchronous closing of the two feeding pipes 105 to stop spraying medicine and water, avoiding waste when not working, and facilitating personnel use.
