[0027] Reference Figure 1-Figure 3 , is an embodiment of the utility model, which provides a soil pollution control sampling device, comprising:

[0028] The main body 100 includes a rod body 101, the rod body 101 is matched with a sleeve 102, the top of the sleeve 102 is reduced in diameter and the reduced diameter section is slidably sleeved on the bottom of the rod body 101, a sampling port is opened on the side of the sleeve 102, and a limit slider 103 is arranged inside the sleeve 102, and the limit slider 103 is fixedly connected to the bottom of the rod body 101;

[0029] The sampling assembly 200 includes a sampling rod 201, which is slidably disposed in the sleeve 102. The side wall of the sleeve 102 is provided with a plurality of sampling slots at equal intervals. A connecting rod 202 is fixedly connected to the top of the sampling rod 201. Through holes are provided at the positions of the rod body 101 and the limit slider 103 facing the sleeve 102. The connecting rod 202 passes through the limit slider 103 and the rod body 101 in sequence through the through holes. A button cap 203 is fixedly connected to the top of the connecting rod 202.

[0030] The reset mechanism 300 includes a lower plate 301, which is fixedly sleeved on the outer side of the limit slider 103, and an upper plate 302 is fixedly sleeved on the outer side of the rod body 101, and the upper plate 302 is arranged opposite to the lower plate 301. A reset spring 303 is also sleeved on the outer side of the rod body 101, and the reset spring 303 is arranged between the lower plate 301 and the upper plate 302, and the two ends of the reset spring are respectively in contact with the lower plate 301 and the upper plate 302;

[0031] The size of the sampling rod 201 matches that of the sleeve 102 .

[0032] In addition, a pressure plate 104 is fixedly mounted on the outside of the sleeve 102. The pressure plate 104 is located below the sampling port of the sleeve 102 and its bottom is flush with the bottom of the sleeve 102. The pressure plate 104 is used to prevent the sleeve 102 from being inserted into the soil. Two groups of cross bars 105 are fixedly connected to the top of the side wall of the rod body 101. The two groups of cross bars 105 are arranged perpendicular to the rod body 101 and are located on the same straight line. The cross bars 105 are used to facilitate the application of force to the device.

[0033] In addition, rubber sleeves 106 are fixedly provided on the outer sides of the two sets of cross bars 105, and anti-skid patterns are provided on the surfaces of the two sets of rubber sleeves 106. The rubber sleeves 106 are used to improve the feel of the device, and the anti-skid patterns are used to prevent slipping.

[0034] It should be noted that the bottom of the sampling rod 201 is conical, which is convenient for insertion into the soil. The sampling rod 201, the connecting rod 202 and the button cap 203 are all made of stainless steel. The rod body 101, the sleeve 102 and the limit slider 103 are all made of stainless steel. Stainless steel is corrosion-resistant. The axes of the rod body 101, the sleeve 102 and the limit slider 103 are arranged to coincide with each other, which is beneficial to ensure the structural stability of the device.

[0035] Working principle: When sampling, the two sets of cross bars 105 are pressed down, and the two sets of cross bars 105 drive the rod body 101 to be pressed down, and the rod body 101 presses down the sampling rod 201 through the limit slider 103, and the sampling rod 201 is pressed into the soil. Since the pressure plate 104 is against the ground, the pressure plate 104, the sleeve 102 and the lower plate 301 are stationary relative to the ground. When the rod body 101 moves down, it drives the upper plate 302 to move down, and the reset spring 303 is compressed, and the sampling rod 201 is pressed into the soil. The soil is inserted into each sampling groove of the sampling rod 201, and the button cap 203 can be appropriately turned to gradually separate the soil in the sampling groove from the surrounding original soil to ensure the integrity of the sampling, and then the two groups of cross bars 105 are pulled up to take out the sampling rod 201, and the reset spring 303 rebounds and the device is reset. When extracting samples, the button cap 203 is turned to make each group of sampling grooves face the sampling port of the sleeve 102 in turn, and the soil samples in each group of sampling grooves can be manually scraped out through the sampling port.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
