Description

Exploratory hole sampling equipment for exploratory mine Technical Field The invention particularly relates to a exploratory hole sampling device for exploratory ores, and relates to the technical field of exploratory ores. Background Prospecting is an engineering that is based on geological exploration to find mineral distribution. The traditional prospecting adopts a mode of drilling and sampling at the same time, and the biggest problem of the traditional prospecting is that a drill rod needs to be frequently lifted and disassembled, so that the prospecting efficiency is low. At present, a mining mode of firstly drilling a hole and then sampling is mostly adopted, and after the hole is drilled at one time, sampling equipment is hung into the hole to sample the wall of the hole, so that the excavation efficiency of the hole can be remarkably improved. The current exploratory hole sampling equipment mainly comprises disk body, telescopic link, sampling drill and sample collection box, and the effect of telescopic link is fixed sampling equipment in the exploratory hole, and the effect of sampling drill is to drilling sample to the wall of the hole. The existing exploratory hole sampling equipment has the following defects: 1. The depth of the exploratory hole can be fixed only, and the sampling efficiency is low; 2. after each sampling, the sampling equipment is lifted out of the exploratory hole to empty the sample collecting box, otherwise, geological samples are confused, and the meaning of exploratory ores is lost; 3. continuous sampling cannot be realized, and the distribution condition of mineral products cannot be distinguished; 4. the diameter is large, the exploratory hole is required to have a larger hole diameter, and the excavation cost of the exploratory hole is increased. Reference is made to: chinese patent CN 112729912B Chinese patent CN 118670793B Chinese patent CN 109490011B Disclosure of Invention In order to overcome the defects in the background technology, the invention discloses a exploratory hole sampling device for exploratory ores, which aims to: 1. continuous sampling of the exploratory hole is realized in a certain depth interval; 2. placing a geological sample into a storage grid with a corresponding height according to the sampling depth; 3. Optimize the structure, reduce equipment diameter. The invention adopts the following technical scheme: Technical proposal A sonde sampling device comprising: the upper fixing plate and the lower fixing plate are provided with a plurality of diameter pushing push rods for fixing the sampling equipment in the exploratory hole; the screw rod and the feed beam are vertically arranged between the upper fixed disc and the lower fixed disc, the screw rod is hollow, and a plurality of storage grids for storing geological samples are equidistantly arranged in the screw rod along the vertical direction; The motor is arranged on the upper fixed disc or the lower fixed disc and is used for driving the screw rod to rotate; The device comprises a screw rod, a feed chute, a slide block, a screw rod, a feed rod and a motor, wherein the screw rod, the feed rod and the motor form a linear motion mechanism which moves along the vertical direction; The driving bevel gear is slidably arranged on the screw rod through a key structure, and the driven bevel gear shaft is horizontally arranged on the sliding block and is in meshed connection with the driving bevel gear; The sampling drill is provided with a drill rod, and the drill rod is connected to the driven bevel gear shaft in a telescopic way through a spline structure; The feeding mechanism is arranged between the sliding block and the sampling drill and used for pushing the sampling drill to move along the radial direction of the exploratory hole; the receiving chute is arranged below the sampling drill and connected with the feeding chute and is used for collecting falling geological samples. After the technical scheme 1 is implemented, compared with the background technology, the invention has the following beneficial effects: 1. The screw has a long length so that the sampling drill has a sufficient moving distance in the vertical direction. Thus, continuous sampling of the exploratory hole by the sampling drill is realized in a certain depth interval of the exploratory hole. 2. Because the feeding chute is correspondingly communicated with the storage grid, geological samples drilled during the period that the sampling drill ascends or descends by one screw pitch can enter the storage grid with the corresponding height through the feeding chute every time the screw rod rotates one round, so that geological prospecting staff can intuitively and clearly establish the relationship between the sampled geological samples and the depth of a exploratory hole, and therefore, the geological structure information is obtained accurately and reliably. 3. The sampling drill requires a motor with larger power to pr
