The test chamber 1 is provided with a drying box 601 inside, and a placement box 603 is placed on the drying box 601. When the soil sample is placed into the placement box 603 and the power supply 13 is turned on, the heating wire 602 inside the drying box 601 starts to work and dries the soil sample in the placement box 603. In this way, the moisture in the soil sample can be removed to meet the requirements of the dryness of the soil sample for subsequent testing. The placement box 603 is provided with four positioning holes 604, and four positioning posts 605 are fixedly connected to the drying box 601. The positioning posts 605 are inserted into the positioning holes 604, and the positioning holes 604 on the placement box 603 are inserted into the positioning posts 605 on the drying box 601, so that the placement box 603 is stably placed on the drying box 601.

[0033] As a technical optimization of this utility model, the bottom of the support frame 401 is provided with a power supply 13, and the test box 1 is provided with an electronic scale 10.

Two inserts 703 are fixedly connected to the box cover 702, and two insert sleeves 704 are fixedly connected to the test box 1. A knob 705 is threadedly connected to the insert sleeve 704. When opening the box cover 702, first unscrew the knob 705 to disengage the inserts 703 from the insert sleeves 704, and then rotate the box cover 702 around the rotating shaft 701.

[0035] As a technical optimization of this utility model, a fixing frame 8 is fixedly connected to the box cover 702, and an elastic sleeve 9 is fixedly connected to the box cover 702. The fixing frame 8 and the elastic sleeve 9 on the box cover 702 can be used to fix some small testing tools or auxiliary items.

[0036] As a technical optimization of this utility model, a U-shaped handle 11 is fixedly connected to the test box 1. A rubber sleeve 12 is fitted on the handle 11. When carrying the device, the hand holds the U-shaped handle 11 with the rubber sleeve 12 on the test box 1. The rubber sleeve 12 can increase the friction and make the grip more comfortable and stable.

[0037] In use, the special soil sample is first placed into the crushing box 201, and the motor 206 (powered by power supply 13) is started. The output of the motor 206 drives the drive shaft 202 to rotate. Since the gears 204 on the two drive shafts 202 mesh with each other, the two drive shafts 202 will rotate synchronously in opposite directions, thereby driving the crushing roller 203 fixed on the drive shaft 202 to rotate. Under the action of the crushing roller 203, the soil sample is crushed. The crushed soil sample falls through the feed pipe 208 at the bottom of the crushing box 201. During the feeding process, the guide plate 207 can guide the soil sample to fall smoothly. To prevent soil samples from accumulating at the bottom of the pulverizing box 201, a U-shaped guide bar 209 at the bottom of the test chamber 1 guides the beaker 5. To retrieve the beaker 5 from the bottom of the feed pipe 208 of the test chamber 1, the retrieving structure 3 can be used. By manually moving the lever 307, the insert rod 304 overcomes the spring force of the spring 306 and is pulled out of the slot 305. At this time, the mounting shaft 301 can be rotated, causing the rotating plate 302 to rotate, thereby opening the corresponding area of ​​the test chamber 1 for easy retrieval of items or placement of soil samples. After the operation is completed, the rotating plate 302 is rotated back to its original position, the lever 307 is released, and under the spring force of the spring 306, the insert rod 304 inserts into the slot. The trough 305 and fixed rotating plate 302 allow soil samples to be placed on the placement rack 402 of the placement structure 4. The beaker 5 is placed at the through hole 403 of the placement rack 402. The placement trough 404 and through hole 403 improve the stability of the beaker 5. If drying is required, the soil sample is placed in the placement box 603. The positioning hole 604 on the placement box 603 connects to the positioning post 605 on the drying box 601, ensuring the placement box 603 is stably placed on the drying box 601. When the power supply 13 is turned on, the heating wire 602 inside the drying box 601 begins to work, drying the soil sample in the placement box 603. This method removes... The moisture content of the soil sample meets the requirements for the dryness of the soil sample in subsequent tests. During the entire testing process, the electronic scale 10 in the test box 1 can be used to weigh the soil sample or related items to provide data support for the test. When opening the box cover 702, first unscrew the knob 705 to disengage the insert 703 from the insert sleeve 704, and then rotate the box cover 702 around the pivot 701. The fixing frame 8 and the elastic sleeve 9 on the box cover 702 can be used to fix some small testing tools or auxiliary items. When carrying the device, hold the U-shaped handle 11 with the rubber sleeve 12 on the test box 1. The rubber sleeve 12 can increase the friction and make the grip more comfortable and stable.
