A smart landfill device for recycling, crushing and disposing of root straw.

Abstract

This invention relates to an intelligent landfill device for root and straw recycling and crushing, belonging to the field of agricultural machinery technology. The device includes a frame, a three-point suspension frame, a root and stubble collection and cutting mechanism, a root and straw collection and crushing mechanism, and an automatic discharge and trenching depth control mechanism. The root and stubble collection and cutting mechanism utilizes a cam mechanism to extend and retract the moving blade during its oblique rotation, with the moving and fixed blades working together to cut the root and stubble, achieving side-throwing of the cut root and stubble. In the root and stubble collection and crushing mechanism, a fan and an auger work together to suck up the initially cut root and stubble and the surrounding straw to the crushing zone, where multiple layers of progressively sized crushing blades crush the root and stubble to varying depths. The automatic discharge and trenching depth control mechanism uses a gravity sensor inside a small box to sense the amount of root and straw, using this feedback information to control the opening and closing of the roller shutter and the trenching depth of the trencher, thereby intelligently adjusting the depth of return to the field based on the quality of the crushed root and straw.

Description

Technical Field

[0001] This invention relates to an intelligent landfill device for recycling, crushing, and shredding root stalks, belonging to the field of agricultural machinery technology. Background Technology

[0002] Traditional methods of stubble treatment are ineffective in crushing stubble, which affects subsequent sowing. Existing machinery has limited functions and cannot accurately collect and crush stubble. The coordination between ditching and stubble treatment is poor, and it cannot automatically adjust the discharge volume and ditching depth in real time according to the amount of crushed stubble, which is not conducive to the return of crushed stubble to the field. Summary of the Invention

[0003] This invention aims to provide a device that integrates root and straw collection, cutting, crushing, discharge, and intelligent adjustment of trenching depth. It uses a telescopic, inclined rotating blade in conjunction with a fixed blade to precisely crush side-thrown root stubble. A fan and an auger collect and transport the pre-cut root stubble and surface straw. Multiple blades of different sizes from top to bottom are used to crush the root and straw. A weight sensor identifies the amount of crushed root and straw and automatically adjusts the amount of discharged root and straw and the trenching depth to achieve efficient utilization of root and straw.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The trencher 16 is fixedly mounted on the output shaft of the third motor 15 and is located between the two fixed plates 44.

[0023] When the root stubble collection and cutting mechanism is in operation, the power unit drives the device forward through the three-point suspension frame 2. The stubble enters the working area of ​​the root stubble collection and cutting mechanism. The fourth battery 22 supplies power to the fourth motor 23. The fourth motor 23 drives the worm gear 35 to rotate, which in turn drives the worm wheel 36 to rotate. The worm wheel 36 drives the moving shaft 20 to rotate, which in turn drives the root digging knife base 24 to rotate. The moving shaft 20 forms a certain angle with the horizontal plane, so that the root digging knife base 24 forms a certain angle with the horizontal plane. The progressive opening and closing angle of the blade on the root digging knife 26 makes the blade fit the shape of the root stubble better, making it easier to pull the root stubble into the root digging knife cover 19. When the root digging knife 26 rotates with the root digging knife base 24, it gradually compresses the spring 25 along the internal track of the root digging knife cover 19. The moving blade on the root digging knife base 24 and the fixed blade on the root digging knife cover 19 inside the root digging knife cover 19 support and cut the dug-out root stubble.

[0024] When the root and straw collection and crushing mechanism is in operation, the fifth battery 28 supplies power to the fifth motor 27, which drives the fan 17 to rotate, sucking the cut root stubble and surface straw into the pipe 32 and into the box 7. The first battery 5 supplies power to the first motor 3, which drives the first gear 4 to rotate, which in turn drives the second gear 6 to rotate, which drives the auger shaft 33 to rotate, thereby driving the auger 30 and the root and straw crushing blades 11 to rotate. The auger 30 presses the initially cut root and straw quantitatively and uniformly to the root and straw crushing blades 11 below for crushing. The root and straw crushing blades 11 are arranged in layers. Under the action of short blades and gravity, the root and straw are thrown to the long blades for further cutting. The setting of the blades from short to long from top to bottom is conducive to deep crushing.

[0025] When the automatic discharge and trenching depth control mechanism is in operation, the rotating root and straw crushing blade 11 throws the crushed root and straw into the small box 31. The second battery 10 supplies power to the second motor 8 and the controller 12 through wires. The second motor 8 drives the fourth gear 37 to rotate, and the fourth gear 37 drives the roller shutter shaft 39 to rotate. The bottom of the small box 31 is equipped with a gravity sensor 29, which transmits the information of the amount of crushed root and straw to the controller 12 to adjust the height of the roller shutter rod 40. When the roller shutter rod 40 rises (falls), the follower rod 13 rotates around the fixed rod sleeve 43. The upper part of the follower rod 13 rotates upward (downward) to lower (raise) the trenching device, thereby increasing (decreasing) the trenching depth. The third battery 14 supplies power to the third motor 15, which drives the trencher 16 to rotate to trench. The crushed root and straw are finally discharged into the trench through the discharge ladder 45.
