Description

Technical Field

[0001] The utility model belongs to the technical field of soil pesticide residue detection devices, in particular to a soil pesticide residue detection device for agricultural planting. Background Art

[0002] During agricultural planting, in order to increase the yield of agricultural products, growers will spray pesticides on agricultural products. However, when applying pesticides, growers may use excessive dosage, too high frequency, improper selection and other problems, resulting in the inability to completely degrade or remove pesticide residues in the soil. Secondly, factors such as soil type, texture, and organic matter content will affect the distribution and degradation rate of pesticides in the soil. Finally, different types of pesticides have different chemical properties and degradation rates. Some pesticides decompose quickly, while others are more difficult to degrade, resulting in a longer residual time in the soil, causing pesticide residues in the soil. In addition, pesticide residues in the soil have the potential to destroy the ecological balance of the soil, reduce soil fertility and productivity, and affect soil quality and health. Pesticide residues may be transported to groundwater or rivers and lakes through runoff, seepage, etc., causing water resource pollution and crops absorbing pesticide residues in the soil. Long-term consumption of agricultural products containing pesticide residues may cause harm to human health. Therefore, it is necessary to detect the amount of pesticide residues in the soil and propose a control plan.

[0003] In a Chinese patent with authorization announcement number CN220455309U, a device for detecting pesticide residues in agricultural planting soil is mentioned. The utility model adds the test soil and dissolving solution into the inner cavity of a fixed box one through a feed port, and by starting a motor one, a rotating column fixedly connected to the upper surface of the motor one is rotated, thereby rotating the stirring rod. Through the action of the stirring rod, the soil can be fully integrated with the dissolving solution, and then discharged through the discharge port. By adding cleaning liquid to the inner cavity of the fixed box one, by starting a motor one, the fixed rod is rotated, thereby rotating the brush. Through the action of the brush, the inner cavity of the fixed box one is cleaned, thereby preventing the next test result from being affected.

[0004] However, the utility model directly adds soil and dissolving liquid into a mixing box for mixing and dissolving, but there may be large aggregates in the soil, so that the dissolving liquid cannot quickly and fully contact the inside of the large aggregates, thereby reducing the dissolution efficiency, and further increasing the error of the test result. Secondly, the utility model adopts a method of directly discharging the mixture of dissolving material and soil during sampling. During detection, soil particles may clog the sampler or detector, and direct discharge for cleaning will cause sewer blockage. Utility Model Content

Finally, the solvent and the soil are stirred by the rotation of the stirring shaft and the stirring blades to improve the uniformity of the mixing.

[0017] 2. The utility model provides a filter net to facilitate detection personnel to collect dissolved liquid and reduce the content of soil in the dissolved liquid during sampling, thereby facilitating monitoring and avoiding clogging of the monitoring sampler or detector. Secondly, when cleaning the device, the filter frame and the filter net can be used to collect and process the soil separately, which can avoid direct discharge into the sewer, causing sewer blockage, or direct discharge, resulting in excessive soil remaining on the inner wall of the mixing box, which is difficult to clean. Finally, the detection device is split into multiple parts for cleaning, which has high cleaning efficiency, strong cleaning force and clean cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] As attached Figure 1 To Attachment Figure 6 As shown:

[0028] Embodiment 1: The utility model provides an agricultural soil pesticide residue detection device, including a main mechanism 100 and an auxiliary mechanism 200. The main mechanism 100 includes a mixing box 101. The upper end of the mixing box 101 is provided with a box cover 102. The upper end of the box cover 102 is fixedly connected to a feed trough 105.

[0029] The auxiliary mechanism 200 includes a support frame 201 fixedly mounted on the upper end of the box cover 102 , and a crushing assembly is installed on one side of the support frame 201 and inside the feed chute 105 .

[0030] The auxiliary mechanism 200 also includes a driving motor 202 fixedly installed on the upper end of the support frame 201, and a driving gear 203 is rotatably installed on the lower end of the support frame 201. The output end of the driving motor 202 is fixedly connected to the upper end of the driving gear 203 through a coupling. The lower end of the driving gear 203 passes through the box cover 102, and a stirring shaft 204 is fixedly installed on the end thereof. The stirring shaft 204 is rotatably connected to the box cover 102, and a plurality of stirring blades 205 are evenly and fixedly installed on the outer surface of the stirring shaft 204.

[0031] The crushing assembly includes a driven gear 206 rotatably mounted on one side of the support frame 201, the driven gear 206 meshes with the driving gear 203, a main gear 207 is fixedly mounted on one end of the driven gear 206, the main gear 207 is rotatably connected to the mixing box 101, two meshing gears 208 are relatively rotatably mounted on the front end of the mixing box 101, both meshing gears 208 are meshed with the main gear 207, an active crushing roller 209 is fixedly mounted on one end of the main gear 207, the active crushing roller 209 is rotatably connected to the feed trough 105, a driven crushing roller 210 is fixedly mounted on the front end of the meshing gear 208, and the driven crushing roller 210 is rotatably connected to the feed trough 105.

[0032] As can be seen from the above, when in use, by placing the detection device on a desktop or the ground, first pour the soil solution from the feed trough 105 into the mixing box 101, then start the drive motor 202 to drive the drive gear 203 to rotate, the drive gear 203 is meshed with the driven gear 206, so that the driven gear 206 drives the main gear 207 to rotate, and then drives the active crushing roller 209 to rotate, and then the gear 207 is meshed with the two meshing gears 208 at both ends, so that both drive the two meshing gears 208 to rotate, and then the two driven crushing rollers 210 are rotated, and the collected soil is gradually poured into the feed trough 105. Under the shear force generated by the meshing of the active crushing roller 209 and the two driven crushing rollers 210, the soil is crushed to form powdery or small granular soil, and then enters the mixing box from the lower end of the feed trough 105. The mixing box 101 is provided with a driving gear 203, and the rotation of the driving gear 203 drives the rotation of the stirring shaft 204, and then drives the stirring blade 205 to rotate, so that the soil and the dissolved liquid inside the mixing box 101 can be stirred and mixed. By setting a crushing component, firstly, the driving motor 202 as a power source can realize the linkage of crushing and stirring, which can save the electric energy of the detection device. Secondly, the shear force generated by the rotation of the active crushing roller 209 and the driven crushing roller 210 can crush the sampled soil, and can improve the efficiency of the dissolved liquid in dissolving organic matter inside the soil, including pesticide residues, and avoid large pieces of soil being wrapped together, so that the dissolved liquid does not completely dissolve the organic matter, thereby reducing the accuracy of the soil detection result.
