[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0030] Refer to Figures 1-12 , the present invention provides a soil sample grinding device, including:

[0031] A grinding assembly, the grinding assembly includes a housing 100, a feed port and a discharge port are provided on the housing 100, two abrasive plates 200 are movably arranged in the housing 100, a rotating shaft 700 is rotatably connected in the housing 100, the rotating shaft 700 extends out of the housing 100, a sand bladder 500 is arranged on the rotating shaft 700, retaining plates 400 are arranged at both ends of the sand bladder 500, the sand bladder 500 is located between the two abrasive plates 200 and the two retaining plates 400, the abrasive plates 200 extend out of the feed port, an adjusting mechanism 600 is arranged on the two abrasive plates 200, the adjusting mechanism 600 is located outside the housing 100, and the housing 100 is fixedly connected to a bracket 800;

[0032] A soil receiving assembly 900, the soil receiving assembly 900 includes a coarse filter screen 930, a fine filter screen 920 and a soil receiving tray 910, the coarse filter screen 930, the fine filter screen 920 and the soil receiving tray 910 are all snap-connected to the bracket 800, the coarse filter screen 930, the fine filter screen 920 and the soil receiving tray 910 are arranged in sequence from top to bottom, and the coarse filter screen 930 is located below the discharge port.

[0033] Pour the collected soil samples into the space between two sand plates 200 from the feed inlet. At this time, the soil samples will be between the sand bladder 500 and the sand plates 200. The retaining plate 400 prevents the soil samples from leaking out. Rotate the rotating shaft 700. At this time, the rotating shaft 700 will drive the sand bladder 500 to rotate. Since the distance between the sand bladder 500 and the sand plates 200 is relatively close, the soil is driven by the sand bladder 500 and ground finer by the abrasive material between the sand plates 200 and the sand bladder 500. Until the size is smaller than the distance between the sand bladder 500 and the sand plates 200, it falls through the gap and flows out from the discharge port of the housing 100 and lands on the coarse filter screen 930. The coarse filter screen 930 first filters the soil samples simply, and then the soil further lands on the fine filter screen 920. After the fine filter screen 920 filters further, it falls into the soil receiving tray 910 below. At this time, the soil in the soil receiving tray 910 is the qualified sample after grinding. The gap between the sand plates 200 and the sand bladder 500 can be adjusted through the adjusting mechanism, so as to adjust the grinding degree of the soil samples.

[0034] In a further optimized solution, the sand plate 200 is movably connected to the inside of the housing 100 through a connecting mechanism 300. Grooves are provided on the sand plate 200. The connecting mechanism 300 includes a fixed rod 310. The fixed rod 310 is clamped in the groove. Snap fasteners 320 are fixedly connected to both ends of the fixed rod 310. The snap fasteners 320 are fixedly connected to the inside of the housing 100. The fixed rod 310 is rotatably arranged in the groove.

[0035] With the fixed rod 310 in the groove, the sand plate 200 can rotate relative to the fixed rod 310, which is convenient for adjusting the gap between the fixed rod 310 and the sand bladder 500.

[0036] In a further optimized solution, the adjusting mechanism 600 includes two adjusting rods 640. Snap fasteners 610 are fixedly connected to both ends of the adjusting rods 640. Threads are provided on the adjusting rods 640. The adjusting rods 640 are threadedly connected with two adjusting knobs 620. Springs 630 are sleeved on the adjusting rods 640. The springs 630 are located between the two adjusting knobs 620. Two first through holes are provided at the upper end of the sand plate 200. The adjusting rods 640 pass through the first through holes of the two sand plates 200. The springs 630 are located between the two sand plates 200. The adjusting knobs 620 are in contact with the sand plate 200.

[0037] The adjusting rods 640 pass through the first through holes of the two sand plates 200. The springs 630 can prevent the two sand plates 200 from fitting onto the sand bladder 500. When it is necessary to reduce the gap between the sand plates 200 and the sand bladder 500, the adjusting knobs 620 can be rotated. The adjusting knobs 620 push the sand plates 200 to move. When it is necessary to increase the gap between the sand plates 200 and the sand bladder 500, the adjusting knobs 620 are rotated outwards. Under the action of the springs 630, the two sand plates 200 will separate.

[0038] For a further optimized solution, the rotating shaft 700 includes a transmission rod 720. Connecting rods are fixedly connected to both ends of the transmission rod 720. Threaded segments 710 are provided on the connecting rods. A handle 730 is fixedly connected to one of the threaded segments 710. The handle 730 is located outside the housing 100. A rubber sleeve 740 is sleeved on the handle 730. A hexagonal through-hole is provided in the abrasive chamber 500. The transmission rod 720 is hexagonal in shape and is inserted into the hexagonal through-hole.

[0039] When it is necessary to rotate the abrasive chamber 500, rotate the handle 730. The handle 730 drives the transmission rod 720 to rotate, and the transmission rod 720 drives the abrasive chamber 500 to rotate. The rubber sleeve 740 makes the rotation of the handle more convenient.

[0040] For a further optimized solution, connection holes are provided in the retaining plate 400. Threads are provided in the connection holes. The threaded segment 710 is threadedly connected in the connection holes.

[0041] The threaded segment 710 is used to connect the retaining plate 400. When the transmission rod 720 rotates, the retaining plate 400 also rotates simultaneously.

[0042] For a further optimized solution, the inner side of the abrasive plate 200 is made of a frosted material, and the outer side of the abrasive chamber 500 is made of a frosted material.

[0043] The frosted material has a better effect on grinding the soil.

[0044] For a further optimized solution, second through-holes are provided on both end faces of the housing 100. Bearings 110 are fixedly connected in the second through-holes. The connecting rods are fixedly connected in the bearings 110.

[0045] The connecting rods are fixedly connected to the inner rings of the bearings 110. The bearings 110 make the rotation of the connecting rods more flexible.

[0046] Method of using this device: Pour the collected soil sample into the space between two sand plates 200 from the feed port. Rotate the handle 730, which drives the transmission rod 720 to rotate. The transmission rod 720 drives the sand bladder 500 to rotate. Since the distance between the sand bladder 500 and the sand plates 200 is relatively close, the soil is driven by the sand bladder 500 and ground finer by the abrasive material between the sand plates 200 and the sand bladder 500. When the size is smaller than the distance between the sand bladder 500 and the sand plates 200, it falls through the gap and flows out from the discharge port of the housing 100, landing on the coarse filter screen 930. The coarse filter screen 930 first conducts a simple filtration on the soil sample, and then the soil further falls onto the fine filter screen 920. After the fine filter screen 920 conducts further filtration, it falls into the soil receiving tray 910 below. At this time, the soil in the soil receiving tray 910 is the qualified sample after grinding. When it is necessary to reduce the gap between the sand plates 200 and the sand bladder 500, the adjustment knob 620 can be rotated. The adjustment knob 620 pushes the sand plates 200 to move. When it is necessary to increase the gap between the sand plates 200 and the sand bladder 500, rotate the adjustment knob 620 outwards. Under the action of the spring 630, the two sand plates 200 will separate, thereby increasing the distance between the sand plates 200 and the sand bladder 500.

[0047] A soil sample grinding device that can control the size of the ground soil particles by adjusting the width of the grinding gap. By manually turning the adjustment knob 620, the grinding gap can be adjusted quickly and labor - saving. The device is small in size and uses a hand - cranking method, with simple operation and no need to carry an additional motor, making soil grinding more convenient and simple.
