Gantry type multipoint grain purchasing intelligent sampling device

Abstract

The invention discloses a gantry type multipoint grain purchasing intelligent sampling device. The device comprises a sampling mechanism and a portal frame body for driving the sampling mechanism to do planar motion.The sampling mechanism comprises a bracket for connecting the portal frame body and the sampling mechanism, a material airflow conveyor, a sample conveying hose, a sampling rod, a vertical driving device and a central control device, wherein the material airflow conveyor, the sample conveying hose, the sampling rod, the vertical driving device and the central control device are connected in sequence; the direct driving device comprises a fixing plate connected to a front end of the bracket, an adjusting frame arranged at aside end of the bracket, a passive groove wheel rotatably connected to an adjusting frame, an active groove wheel rotatably connected to the fixing plate, and a groove wheel driving device arranged on the fixing plate and used for driving the active groovewheel to rotate; and the active groove wheel and the passive groove wheel are oppositely arranged, and a space for accommodating the sampling rod is formed between the active groove wheel and the passive groove wheel. A problem of poor structural stability of a slender rod of the sampling rod is solved, a phenomenon that the sampling rod is bent and even broken is effectively avoided, and a depthof the sampling rod inserted into a grain pile is easily accurate through fixed-point control.

Description

technical field [0001] The invention relates to the field of grain sampling equipment, in particular to a gantry type multi-point grain acquisition intelligent sampling device. Background technique [0002] Although there are many types of sampling equipment currently on the market, there are no more than two types. One is a small and simple manual hand-held sampler, and the other is a manually operated medium or large electric or hydraulic mechanical sampler. The sampling device is inseparable from manual on-site operation, and the personnel in charge of sampling will inevitably have direct or indirect contact with the material, and even the direct beneficiary. In this way, some human factors may occur, resulting in a large deviation between the sample sent to the inspection and testing personnel and the actual goods, making the data in the inspection and testing report not objective and fair, and allowing the user to purchase a product that is far from the actual demand. ...

Problems solved by technology

[0002] Although there are many types of sampling equipment currently on the market, there are no more than two types. One is a small and simple manual hand-held sampler, and the other is a manually operated medium or large electric or hydraulic mechanical sampler. Sampling devices are inseparable from manual on-site operation, and the personnel in charge of sampling will inevitably come into direct or indirect contact with materials, and even contact with direct beneficiaries.

In this way, some human factors may occur, resulting in a large deviation between the sample sent to the inspection and testing personnel and the actual goods, making the data in the inspection and testing report not objective and fair, and allowing the user to purchase a product that is far from the actual demand. Raw materials, thus causing irreparable losses to demand enterprises

[0003] Secondly, the existing large-scale electric or hydraulic mechanical samplers are all driven by the driving device to drive the large frame to move vertically up and down so that the slender sample rod can be mixed into the bucket or granary. The structural stability of the rod itself is poor, and the market may cause the cutting rod to bend or even break during use; at the same time, the large frame body is large in size, heavy in weight, and has a large up-and-down motion inertia, which is not easy to control at a fixed point, often causing the cutting rod to be inserted into the grain pile the depth is not accurate enough
