Embodiment Construction
[0010] The following describes the creative implementation of the present invention in detail with reference to the accompanying drawings. A kind of seed bed with an automatic control unit for the width of straw cleaning. A parallel four-bar rack 2 is fixed on the single rack 1, and the lower part of the rear side of the parallel four-bar rack 2 is displaced back and forth and inclined to each other through the tray 3 Two arcuate sawtooth cleaning trays 4 are rotatably equipped, and an electric linear push rod 6 is vertically hinged on the lower side of the upper end of the parallel four-bar frame 2. On the lower side of the parallel four-bar frame 2 The S-shaped pressure sensor 5 is hinged on the upper end through the lower connecting piece 9. The upper connecting piece 7 is arranged between the lower part of the electric linear actuator 6 and the upper part of the S-shaped pressure sensor 5. The electric linear actuator is connected by the upper connecting piece 7. 6 is conne...

The invention relates to a seedbed band straw cleaning width automatic control unit, and belongs to agricultural machinery. An electric linear push rod is vertically mounted on the lower side of the upper end of a parallel four-bar frame in a hinged manner, an S-shaped pressure sensor is hinged to the upper end of the lower side of the parallel four-bar frame through a lower connector, the electric linear push rod is connected with the S-shaped pressure sensor by an upper connector, the electric linear push rod and the S-shaped pressure sensor are communicated with a width controller through leads, and the width controller comprises a relay module, a microcontroller, a transmitting amplifier, a display screen and a key module. Based on the design of seedbed band straw cleaning width only associated with the soil inserting depth of a cambered surface saw tooth straw cleaning disk, the electric linear push rod is cooperatively matched with the S-shaped pressure sensor, consistency of seedbed band straw cleaning widths is ensured by real-time adjustment, and the unit is simple and reasonable in structure, high in control automation degree and adaptability and good in straw cleaning effect.
Description
Technical field [0001] The invention belongs to an agricultural machine, and mainly relates to a seed bed strip ground preparation operation component. Background technique [0002] The consistency and stability of the width of the seedbed strip is one of the important indicators for evaluating the operation quality of the seedbed straw cleaning device. In seed bed strip plowing and land preparation operations, the consistent and stable seed bed strip cleaning width can ensure that the loosening and crushing device complete the loosening and crushing operations under good working conditions to improve the seed bed strip The quality and effect of land preparation operations. However, due to the undulation of the field surface, poor flatness, combined with the influence of many factors such as straw residue coverage, different lengths of straw, uneven spreading and laying, etc., the currently used seed bed with straw cleaning device is prone to arcing when operating. The phenomen...
