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 described soil sampling drill is provided with involute spur gear, namely driving spur gear 9, and the tooth of described driving spur gear 9 is thicker, is used in cooperation with the passive spur gear 12 on the described driving dial, and described The upper end surface of the driving spur gear 9 has a reduction device shaft hole, which cooperates with th...

Abstract

The invention discloses a mechanical soil-sampling device. The mechanical soil-sampling device comprises motors, a soil-sampling drill, a soil collection disc and a fixing box. A spiral inner groove is arranged at a lower end of the soil-sampling drill; outer edges of the spiral inner groove are provided with extended small flanges; the bottom end of the soil-sampling drill is processed into a cone-shaped drill head; an upper end of the soil-sampling drill is provided with a driven spur gear; the driven spur gear and a driving spur gear cooperate with each other thereby moving; the driving spur gear is installed on a main shaft of a first decelerator; the first decelerator is connected to an output shaft of a first motor; the main shaft of the first decelerator is fixedly connected to the upper end of the soil-sampling drill; the soil-sampling drill vertically and rotatingly move to pass through one of soil collection chambers; a baffle is installed in the fixing box and is located above the soil collection disc; and an end of the baffle extends into the spiral inner groove of the soil-sampling drill. The mechanical soil-sampling device has the advantages of convenient use, reliable running, simple structure, high efficiency and good applicability.

Description

technical field [0001] The invention relates to a mechanical soil sampling device, in particular to a soft and moist soil collecting device. Background technique [0002] At present, known soil samplers are classified according to the type of power drive, and are divided into manual soil samplers and mechanical soil samplers. Its basic structure is composed of sampling head, connecting rod and power drive unit. The driving unit of the manual soil sampler is a handle, the driving unit of the mechanical soil sampler is an electric motor, etc. The operation process is to insert the sampling head vertically into the soil, then press the soil into the sampling head by pressing down, turning, etc., and finally pull the soil sample out of the soil layer by lifting, rotating, etc., and then separate the soil sample, and complete the process. sampling. When the manual soil sampler is lifted up to extract the sampler from the soil, it is laborious and time-consuming, and sometimes ...
