Description

Technical Field

[0001] The utility model belongs to the technical field of pesticide detection, and particularly relates to a pesticide detection pre-processing device. Background Art

[0002] Pesticide testing is the process of qualitative or quantitative analysis of pesticide residues contained in agricultural products, food, environmental samples, etc., to evaluate whether they meet the relevant standards of food safety and environmental protection. Pesticide testing can ensure food safety, prevent pesticide residues from causing potential harm to human health, and monitor the use of pesticides in agricultural production and its impact on the environment. The pesticide testing pretreatment device is a device used to pretreat samples before formal analysis and testing. The existing pesticide testing pretreatment device uses a single stirring mechanism driven by a motor to achieve mixing of pesticides, which is convenient for subsequent testing. Its stirring mechanism is single and cannot lift the denser liquid for stirring and mixing, resulting in it being unable to be mixed evenly.

[0003] For example, the utility model with announcement number CN219722500U discloses a pesticide detection pretreatment device, in which the output shaft at one end of the motor is fixedly connected to a rotating rod, and stirring rods are arranged at equal distances on the outer wall of the rotating rod. In this patent scheme, the stirring rod is driven by a motor to stir the liquid medicine for pretreatment. The liquid medicine with higher density cannot be lifted to the stirring area, resulting in inadequate mixing with other liquid medicines. This may cause uneven distribution of active ingredients in the liquid medicine, affecting the data of subsequent pesticide detection. Utility Model Content

[0004] In view of this, the utility model aims to provide a pesticide detection pretreatment device to address the deficiencies of the prior art. The device can lift a denser liquid medicine for stirring and mixing, so that the active ingredients in the liquid medicine can be fully mixed, reducing the time required for stirring pretreatment and making the data of subsequent pesticide detection more accurate.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a pesticide detection pretreatment device, including a mounting frame, a treatment barrel is arranged inside the mounting frame, a liquid inlet pipe is arranged in the liquid inlet hole opened at the upper end of the treatment barrel, a feed plate is hinged in the feed port opened at the upper end of the treatment barrel through a hinge, a discharge pipe is arranged in the discharge hole opened at the lower end of the treatment barrel, a solenoid valve is connected in series in the middle of the discharge pipe, a pretreatment mechanism is arranged inside the treatment barrel, the pretreatment mechanism includes a rotating shaft rotatably arranged at the upper end of the treatment barrel, a connecting plate is fixedly sleeved on the outer arc surface of the rotating shaft, rotating columns are rotatably arranged on the left and right sides of the connecting plate, and the outer arc surfaces of the two rotating columns are respectively rotatably arranged A plurality of stirring blades are arranged on the top, gears are arranged on the upper ends of the two rotating columns, an inner gear ring is arranged on the upper end of the inner arc surface of the processing barrel, two gears are meshed and connected with an inner gear ring, a lifting assembly is arranged at the lower end of the rotating shaft, an electric drive unit for driving the rotating shaft to rotate is arranged at the upper end of the processing barrel, the lifting assembly includes a reciprocating screw arranged at the lower end of the rotating shaft, a rectangular plate is arranged at the lower end of the inner arc surface of the processing barrel, a limiting column is arranged at the upper end of the rectangular plate, a lifting disk is slidably connected to the outer arc surface of the limiting column, the lifting disk is threadedly connected to the reciprocating screw, the electric drive unit includes a motor arranged at the upper end of the processing barrel, and the output shaft of the motor is connected to the upper end of the rotating shaft through a coupling.

[0006] As a further improvement of the utility model, two mounting holes are respectively provided on the left and right sides of the mounting frame.

[0007] As a further improvement of the utility model, two slide rails corresponding to left and right positions are arranged at the inner lower end of the mounting frame, a collection box is slidably connected between the two slide rails, and a handle is arranged on the front side of the collection box.

[0008] As a further improvement of the utility model, a control panel is arranged at the left end of the front side of the mounting frame, and the motor and the solenoid valve are electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Firstly, the liquid medicine that needs to be treated before testing is added from the liquid inlet pipe into the interior of the treatment barrel, and then the solid pesticide that needs to be treated before testing is added from the feed port into the interior of the treatment barrel by opening the feed plate. After the addition is completed, the motor is turned on by controlling the output shaft to rotate and drive the reciprocating screw at the lower end of the rotating shaft to rotate, thereby driving the lifting plate threadedly connected thereto to move back and forth up and down under the restriction of the limit column to lift up the pesticide with higher density or deposited on the bottom wall of the treatment barrel. The liquid medicine with higher density can be lifted for stirring and mixing treatment, and the active ingredients in the liquid medicine can be fully mixed, so that the time required for stirring pre-treatment is reduced and the data of subsequent pesticide testing is more accurate.

[0011] Secondly, by rotating the shaft, the connecting plate is driven to rotate, so that the stirring blades on the two rotating columns at the upper end revolve to stir the pesticide. At the same time, the gears on the rotating columns on both sides are affected by the meshing relationship of the internal gear rings and begin to drive the stirring blades on the rotating columns to rotate and stir the pesticide, which can greatly increase the stirring efficiency of pesticide pretreatment.

[0012] Thirdly, by opening the solenoid valve, the liquid medicine after stirring is allowed to flow out from the discharge pipe to the inside of the collection box. The staff can take out the collection box by the handle and test the liquid medicine inside, which is convenient for the staff to unload the material for subsequent testing.

[0013] Fourthly, the pre-processing device can be quickly installed through the mounting holes on the mounting frame, which can make the pre-processing device more stable during operation. BRIEF DESCRIPTION OF THE DRAWINGS
