Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings.
[0033] refer to Figure 1~Figure 16 , The soil sampling device consists of a box, a soil sampling drill, a motor, a reduction device, a soil sampling disc, a disc chassis, a grooved wheel mechanism, a ratchet mechanism and a rack and pinion mechanism. The lower end of the soil sampling drill is made into a pointed round head, and a long special spiral inner groove is arranged above the tip of the groove sampling drill. The structure diagram of the soil sampling drill is as follows figure 1 shown. The upper end of the soil sampling drill is provided with an involute spur gear, i.e. a drive spur gear 9. The teeth of the drive spur gear 9 are thicker, and are used in conjunction with the passive spur gear 12 on the drive dial. The upper end surface of the driving spur gear 9 has a reduction device shaft hole, which cooperates with the output shaft of the first reduction...
