Problems solved by technology

[0002] Most of the existing automatic sampling machines use simple mechanisms such as timers, limit switches or counters, which have a low degree of automation and a high failure rate. For example, using limit switches to locate sampling points has the disadvantage of inaccurate mechanical inertia
A small number of automatic samplers are developed with programmable technology, but in the process of equipment development, the adaptability of the equipment to the field environment is not considered, especially the electromagnetic interference and acid-base corrosion in the chemical and fertilizer industries, so the reliability is not high; the biggest problem is still There is no model specially designed for the protection of sampling samples in complex environments

Abstract

The invention discloses an automatic sampling system which comprises a host system and an auxiliary system, wherein the host system comprises a main control module, a speed reducing stepping motor, a stepping driver and a discharging servo motor; the stepping driver is connected with the speed reducing stepping motor; the auxiliary system comprises a box and a sealed servo motor; the sealed servo motor is arranged on the box; a main shaft rotating arm is arranged on the speed reducing stepping motor; a sampling head is fixedly arranged on the end part of the main shaft rotating arm; the discharging servo motor is arranged at the end part of the main shaft rotating arm; a rotating piece is fixedly arranged on a rotating shaft of the discharging servo motor and can be used for blocking the bottom of the sampling head during the sampling; a material guide pipe is arranged in the box of the auxiliary system; an inner film bag is fixedly arranged at an upper end port of the material guide pipe; a sealing cover is fixedly arranged on a rotating shaft of the sealed servo motor and is used for covering the upper end port of the material guide pipe. The automatic sampling system is suitable for sampling matters such as powder and particles, and also suitable for sampling objects with end parts during the transport in the industries of a chemical fertilizer, grains, food and medicines.

Description

technical field [0001] The invention relates to an automatic sampling system, which is used for sampling articles at the end of conveyor belts in industries such as chemical fertilizers, grain, food, and medicine. Background technique [0002] Most of the existing automatic sampling machines use simple mechanisms such as timers, limit switches or counters, which have a low degree of automation and a high failure rate. For example, using limit switches to locate sampling points has the disadvantage of inaccurate mechanical inertia. A small number of automatic samplers are developed with programmable technology, but in the process of equipment development, the adaptability of the equipment to the field environment is not considered, especially the electromagnetic interference and acid-base corrosion in the chemical and fertilizer industries, so the reliability is not high; the biggest problem is still There is no model designed to protect sampling samples in complex environmen...
