A material level detection device and method for a straw baler

Abstract

The invention relates to a material level detection device and method of a straw baler, belonging to the technical field of agricultural machinery. The technical solution is: the detection blade (21) on the detection rod (16) enters the feed bin (5) of the straw baler at a predetermined height position, and the motor housing (14) does not move when the motor shaft continues to rotate; when the feed bin (5) ) reaches the predetermined height, the reaction force drives the motor suspended in the box (10) to rotate in reverse, and the positioning piece (20) triggers the action of the output node close to the opening (19) to control the feeding mechanism of the straw baler Stop feeding. The beneficial effects of the invention are: the actual height of the material in the silo can be visually determined without being affected by the surrounding environment, and the produced straw bales can be guaranteed to meet the standard requirements, the structure is simple, the maintenance cost is low, and the use is convenient.

Description

technical field [0001] The invention relates to a material level detection device and method of a straw baler, belonging to the technical field of agricultural machinery. Background technique [0002] Straw is the main by-product of crops and an important biological resource for industry and agriculture. Crop straw is rich in nutrients and can be used as fertilizer, feed, living fuel and raw materials for industrial and sideline production. At present, a large amount of remaining straw is actually a huge resource that has not been used and has been burned. Do a good job in the comprehensive utilization of crop straw, turn waste into treasure, and turn harm into profit. For a country with a large population and a relatively short agricultural resource, it has It has great practical and strategic significance. At the same time, while my country is vigorously improving resource utilization, it also has strategic significance for sustainable development in protecting ecology and ...

Problems solved by technology

The problems existing in the existing technology are: because the actual height of the material in the silo cannot be determined intuitively, the estimated height is prone to errors; the types of straw are ever-changing, and the specific gravity varies greatly, and the height of the material in the silo is estimated by the weight of the material There is a large deviation, which is easily affected by the surrounding environment, and the produced straw bales cannot meet the standard requirements; in addition, the weight sensor needs to match the weighing system, which has a complex structure, high maintenance costs, and inconvenient use
