Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] Reference Figure 1-Figure 3The utility model provides an embodiment: a drying and screening device for soil detection, comprising a drying and screening cylinder 1, wherein a plurality of drying chambers 2 are arranged inside the drying and screening cylinder 1, and stirring rods 15 are arranged inside the plurality of drying chambers 2 for stirring the poured soil, and a linkage driving mechanism is arranged on the top of the drying and screening cylinder 1, and the linkage driving mechanism drives the stirring rods 15 inside the plurality of drying chambers 2 to rotate, so as to realize simultaneous stirring of different types of soil inside the plurality of drying chambers 2, and the number of the drying chambers 2 is specifically 4, and the linkage driving mechanism comprises a support frame 10 fixed on the top of the drying and screening cylinder 1, a driving motor 9 is fixed on the top of the support frame 10, a driving gear 11 is fixed on the driving end of the driving motor 9, and a driven gear 12 is fixedly sleeved on the top of the stirring rod 15, and the driven gear 12 is meshed and connected with the driving gear 11. When it is used specifically, it only needs to start the driving motor 9, and the driving motor 9 drives the driving gear 11 to rotate, so that the driving gear 11 can drive the plurality of driven gears 12 to rotate, thereby driving the plurality of stirring rods 15 to rotate in linkage.

[0028] An electric heating wire is arranged inside the stirring rod 15. The stirring rod 15 is made of heat-conducting metal and can conduct heat from the electric heating wire. In the process of stirring the soil, the soil is dried to improve the drying efficiency. A rotating power connector 13 is connected to the top of the stirring rod 15 to energize the electric heating wire and prevent the electric heating wire from interfering with the internal electric heater when the stirring rod 15 rotates. A discharge valve 5 is arranged inside the drying chamber 2 and below the stirring rod 15. The discharge valve 5 is an electric valve. After drying is completed, the discharge valve 5 can be opened to discharge the dried soil.

[0029] A screening drawer 6 is arranged below the discharge valve 5, and a screening net 14 is installed on the inner bottom wall of the screening drawer 6. The discharged dried soil will directly fall into the screening drawer 6. The screening drawer 6 is connected to the drying screening cylinder 1 by pulling. A lower hopper 7 is arranged below the screening drawer 6, and the bottom end of the lower hopper 7 extends to the bottom of the drying screening cylinder 1. A vibration motor 8 is installed on the lower surface of the drying screening cylinder 1. A plurality of shock-absorbing springs 4 are installed at the bottom of the drying screening cylinder 1, and a base 3 is fixed to the bottom ends of the plurality of shock-absorbing springs 4.
