Abstract

The invention relates to a material level detection device and method of a straw baler, and belongs to the technical field of agricultural machinery. According to the technical scheme, a detection blade (21) on a detection rod (16) enters a preset height position of a stock bin (5) of the straw baler, and a motor shell (14) does not move when a motor shaft continues to rotate; and when materials in the stock bin (5) reach the preset height, counter-acting force drives a motor arranged in the box body (10) in a suspended manner to rotate reversely, a positioning piece (20) triggers an output joint close to a switch (19) to act, and a feeding mechanism of the straw baler is controlled to stop feeding. The material level detection device has the advantages that the actual height of the materials in the stock bin can be visually determined, affects by the surrounding environment are avoided, it is guaranteed that produced straw bags meet the standard requirement, the structure is simple, the maintenance cost is low, and 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 in 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. To do a good job in the comprehensive utilization of crop straw, turn waste into wealth, and turn harm into profit is of great significance to a country with a large population and relatively short agricultural resources. At the same time, while vigorously improving the utilization rate of resources in our country, it also has strategic significance for sustainable development in protecting the ecology and the environment. ...
