Swing arm moving roller detection device for irregular bulk material stack height detection

Abstract

The invention provides a swing arm moving roller type detection device for detecting the height of an irregular bulk material pile. The swing arm moving roller type detection device comprises a squarepipe support arranged at the top of a stock bin, a rack, a gear, a motor, a mechanical arm and a roller. The gear is mounted on a gear frame, the gear frame is sleeved on the square pipe support, twobearing plates are fixedly arranged at the bottom of the gear frame, the top ends of the two bearing plates are connected by small wheels that abut against the lower surface of the square pipe support, the lower ends of the two bearing plates are fixedly arranged on the front side and the rear side of the square pipe respectively, and the mechanical arm penetrates through the square pipe and thenis limited through a limiting pin, and the roller is arranged at the tail end of the mechanical arm. The motor drives the mechanical arm to horizontally reciprocate on the irregular bulk material pile, an inductance approach switch sensor detection point is arranged at the top end of the mechanical arm, and an inductance approach switch sensor is arranged at the bottom of the gear frame. The device is simple in structure and high in accuracy of detecting the height of the irregular bulk material pile, and provides possibility for realizing full-automatic operation of a bundling machine.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and in particular relates to a swing arm moving roller type detection device for height detection of irregular bulk material piles. Background technique [0002] The working principle of the feed square baler: the first step is to feed the forage into the silo, and the second step is to judge whether the feeding amount of the silo meets the demand for compression molding. When the demand is reached, the lower pressure cylinder, side pressure cylinder, Three hydraulic cylinders such as the front pressure cylinder squeeze the bale in order to form it and push it into the netting (rope) device for binding, and finally form a bale and push it out to the ground by the next bale. [0003] The currently available square balers that use the winch feeding method for the purpose of collecting feed basically use infrared detection technology to sense the feed in the method of judging whether the feedin...

Problems solved by technology

[0005] 2. The material to be detected is an irregular bulk material. A single section of straw protrudes, which may block and reflect the infrared rays emitted by the sensor. In this case, the detection system will wrongly judge that the height of the material has reached the preset value. value, and start the next step of feeding the material into the compression chamber for extrusion. At this time, the bale will not be formed due to insufficient material, and a series of loose bales, invalid wrapping (rope) (material waste), manual cleaning, etc. will occur. non-performance work

[0006] 3. Once the detection method of the infrared sensor fails or is discarded, an important part of the packaging operation - the judgment of the material storage in the silo is out of control. The timing of materials is very inaccurate and inefficient. It requires high operating experience of the operator and cannot achieve efficient and fast automation requirements.
