Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue detection, in particular to a rapid dilution device for pesticide residue detection. Background Art

[0002] By regularly testing soil pesticide residues, pesticide pollution problems can be discovered in time, so that effective measures can be taken to ensure the quality and safety of agricultural products. In the process of testing soil with pesticide residues, the soil needs to be diluted. For example, the dilution device for detecting soil with pesticide residues disclosed in Patent No. CN217180211U drives the rotating rod and the stirring and crushing knife to rotate through a motor, so that the stirring and crushing knife fully dilutes the soil in the inner cavity of the dilution cylinder, and the liquid will not splash during the dilution process. However, the crushing knife of the device is only arranged at the bottom of the cylinder, and the soil in the middle and upper parts of the cylinder cannot be well integrated with water, resulting in poor dilution effect, which is easy to affect the accuracy of subsequent detection. Moreover, the dilution is only performed through the stirring structure, and the dilution speed is slow. Therefore, a rapid dilution device for detecting pesticide residues is needed.

[0021] Soil and diluent are added into the dilution device body 1 through the feed port 5. When the soil and diluent are added, they squeeze the baffle 7 and discharge the material through the gap between the baffles 7. After the soil and diluent are added, the baffle 7 is lifted up and reset under the action of the reset spring 10.

[0022] The bottom end of the feed port 5 is shielded to prevent splashing during subsequent dilution, and no additional cover is required, which facilitates feeding and subsequent sampling of the dilution liquid;

[0023] Guide grooves 16 are provided on both sides of the buffer sleeve 6, and guide blocks matching the guide grooves 16 are provided on both sides of the movable plate 11 to limit the range of motion of the return spring 10 to prevent distortion and deviation;

[0024] A driving shaft 8 and a driven shaft 2 are respectively disposed at both ends of the dilution device body 1, and a driving wheel 20 and a driven wheel 18 are respectively disposed at the bottom of the driving shaft 8 and the driven shaft 2, and the driving wheel 20 and the driven wheel 18 are connected by a belt 19;

[0025] A rotary drive mechanism 9 is fixed to one end of the bottom of the dilution device body 1, and the output end of the rotary drive mechanism 9 is connected to the driving shaft 8;

[0026] After the soil and diluent are added into the dilution device body 1, the rotary drive mechanism 9 drives the driving shaft 8 to rotate, so that the driving wheel 20 rotates. The driving wheel 20 is connected to the driven wheel 18 through the belt 19, so that the driven wheel 18 and the driven shaft 2 rotate together;

[0027] The driving shaft 8 and the driven shaft 2 are both provided with spiral blades 17. The spiral blades 17 rotate to fully dilute the soil, thereby expanding the mixing range without increasing the driving equipment.

[0028] When the spiral blade 17 rotates, the soil at the bottom of the dilution device body 1 can be stirred upward to improve the fusion effect of the soil and the diluent. The spiral blade 17 is evenly distributed with circular protrusions, which have a certain crushing effect on the soil.

[0029] A heating jacket 3 is arranged outside the dilution device body 1, and a heating resistor ring 4 is arranged at the central position inside the heating jacket 3;

[0033] The specific model specifications of the rotary drive mechanism 9 and the heating resistor ring 4 need to be determined by selection calculation based on the specification parameters of the device. The selection calculation method is a prior art and will not be described in detail.

[0034] Working principle: When the embodiment of the present application is in use, soil and diluent are added into the dilution device body 1 through the feed port 5. When the soil and diluent are added, the baffle 7 is squeezed and the material is discharged through the gap between the baffles 7. After the soil and diluent are added, the baffle 7 is lifted and reset under the action of the reset spring 10, and the bottom end of the feed port 5 is blocked to prevent splashing during subsequent dilution. There is no need to set up an additional cover body, which is convenient for feeding and subsequent sampling of the diluent. Then, the rotating drive mechanism 9 drives the driving shaft 8 to rotate, so that the driving wheel 20 rotates. The driving wheel 20 is connected to the driven wheel 18 through the belt 19. The driven wheel 18 and the driven shaft 2 are connected, thereby causing the driven wheel 18 and the driven shaft 2 to rotate together, driving the spiral blade 17 to rotate, and the soil is fully diluted. The stirring range can be expanded without increasing the driving equipment. When the spiral blade 17 rotates, the soil at the bottom end of the dilution device body 1 can be stirred upward to improve the fusion effect of the soil and the diluent. At the same time, the heating resistor ring 4 in the heating sleeve 3 generates heat after being energized, and the heat is evenly transferred to the heat-conducting ring 14 through the heat-conducting rod 13. The heat-conducting ring 14 is hooped on the outer wall of the dilution device body 1, and the temperature inside the dilution device body 1 can be evenly and quickly increased, thereby increasing the dilution speed of the soil and improving the work efficiency.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
