Description

Technical Field

[0001] The invention relates to the technical field of paddy field slurry stirring and leveling machines, in particular to a paddy field slurry stirring and leveling machine. Background Art

[0002] A paddy field slurry leveler is an agricultural machine specially used for paddy field cultivation. Its main function is to chop and stir the soaked paddy field soil into slurry, and press the stubble, stems or weeds into the mud, thereby returning the straw to the field and leveling the soil.

[0003] At present, when the existing horizontal slurry grader performs slurrying operation in the paddy field, it rotates the stirring shaft through the driving mechanism, and then makes the multiple slurrying blades on the stirring shaft rotate synchronously, so as to achieve the stirring of the paddy field into slurry. However, when performing slurrying operation on the paddy field with excessive soil moisture and heavy viscosity, it is easy to cause the soil to stick to the slurrying blade. The slurrying blade has a lot of soil adhering to it, which not only increases the resistance of the slurrying blade in the soil, causing the slurry machine to consume more power to overcome this resistance, thereby reducing the slurrying efficiency, but also hinders the slurrying blade from fully crushing the soil in the paddy field, resulting in uneven soil fragmentation, affecting the growth and development of the rice root system, and further causing wear of the slurrying blade.

[0055] A supporting mechanism 3, wherein a plurality of supporting mechanisms 3 are provided, and the plurality of supporting mechanisms 3 respectively penetrate the moving opening 21;

[0056] The support mechanism 3 includes a support block 31, which slides through the moving opening 21. Two guide blocks 32 are installed on the support block 31. The two guide blocks 32 limit the support block 31 so that the support block 31 can stably move along the top of the moving opening 21. The two guide blocks 32 are located above the moving opening 21 and are slidably connected to the bottom end of the front cover 2. A positioning hole 312 is provided on the top of the support block 31 for positioning it with the positioning mechanism 4.

[0057] A connecting mechanism 33 is provided with a connecting hole 311 on one side of the supporting block 31 and close to the front cover 2. The connecting mechanism 33 is installed on the inner side of the front cover 2 and connected to the connecting hole 311. The connecting mechanism 33 includes a connecting plate 331 fixedly installed on the inner side of the front cover 2. A connecting spring 332 is fixedly installed on one side of the connecting plate 331. In the present invention, a telescopic protective sleeve can also be provided on the outer side of the connecting spring 332 to protect the connecting spring 332. The telescopic protective sleeve is connected between the connecting plate 331 and the supporting block 31. One end of the connecting spring 332 away from the connecting plate 331 is fixedly connected to the inside of the connecting hole 311. In the present invention, due to the limitation of the moving port 21, the connecting spring 332 is always in a compressed state.

[0058] The support rod 34 is fixedly mounted on the bottom of the support block 31 and is located below the movable opening 21. The support rod 34 is detachably mounted on the bottom of the support block 31, that is, two connecting ears are arranged on the top of the support rod 34, and projections are arranged at the positions corresponding to the two connecting ears at the bottom of the support block 31, and locking bolts are threadedly connected at the connecting ears, so that the support rod 34 and the support block 31 can be quickly disassembled by removing the locking bolts, that is, in the actual operation process, the position of the support rod 34 is easily impacted by paddy field soil or hard stones, resulting in the support rod 34 being damaged. In the present invention, the support rod 34 can be replaced separately, thereby ensuring that the scraping mechanism 6 can scrape the soil on the outside of the slurry blade 15. The scraping mechanism 6 and the detection mechanism 7 are respectively connected to the two sides of the support rod 34;

[0059] At the same time, in the present application, the support rod 34 provided at the forward end of the agitator blade 15 can also chop the soil of the paddy field, thereby assisting the agitator blade 15 to fully agitate the paddy field soil;

[0060] A positioning mechanism 4, which is installed on the top of the front cover 2 and is used to position the multiple supporting mechanisms 3;

[0061] The positioning mechanism 4 includes a plurality of positioning rods 41, and the bottoms of the plurality of positioning rods 41 are respectively slidably connected to the positioning holes 312 at the top of the support block 31;

[0062] A positioning plate 42 is fixedly mounted on the top of the plurality of positioning rods 41 , and an adjusting mechanism 43 for adjusting the position of the positioning plate 42 is installed inside the front cover 2 .

[0063] The adjustment mechanism 43 includes a slide bar 431 that slides through one end of the positioning rod 41, and the slide bar 431 is fixedly installed inside the front cover 2;

[0064] A threaded hole is provided at one end of the positioning plate 42 away from the sliding rod 431, and a lifting screw rod 432 passes through the threaded hole. The positioning plate 42 is threadedly connected to the lifting screw rod 432 through the threaded hole. A rotating member 8 for driving the lifting screw rod 432 is installed on the top of the front cover 2. The lifting screw rod 432 is rotatably connected to the front cover 2, so that the lifting screw rod 432 is further rotated relative to the front cover 2 through the operation of the rotating member 8. When the lifting screw rod 432 rotates, a driving force is provided to the positioning plate 42 thereon. Because the positioning plate 42 is guided by the sliding rod 431 and the front cover 2, the positioning plate 42 is further moved along the vertical plane, so that the positioning plate 42 drives the multiple positioning rods 41 thereon to move along the inside of the front cover 2.

[0065] A scraping mechanism 6, the scraping mechanism 6 is installed on the side of the support mechanism 3 close to the paddle blade 15, and the scraping mechanism 6 is used to scrape the soil attached to the outside of the paddle blade 15, the scraping mechanism 6 includes a scraping frame 61 fixedly installed on the side of the support rod 34 close to the paddle blade 15, and a scraping groove 611 is provided on the inner side of the scraping frame 61, and the shape of the scraping frame 61 is adapted to the shape of the paddle blade 15, so that the soil on the outside of the paddle blade 15 can be fully scraped, and when the paddle blade 15 rotates to the scraping groove 611, the scraping groove 611 scrapes the soil on the outside of the paddle blade 15;

[0066] Specific implementation process: while multiple groups of agitating blades 15 rotate with the stirring shaft 14, multiple support blocks 31 are positioned by the positioning rods 41 thereon, thereby fixing the support blocks 31 relative to the front cover 2, and further making the support rods 34 at the bottom of the support blocks 31 correspondingly distributed on the outside of each group of agitating blades 15. At the same time, through the rotation of the agitating blades 15, they can move along the scraping groove 611. While the agitating blades 15 move, the scraping groove 611 can scrape off the soil on the outside of the agitating blades 15, thereby ensuring that the agitating blades 15 can fully and evenly agitate the paddy field soil.

[0067] A pushing mechanism 5, which is installed on a side of the front cover 2 close to the mud guard 11, and is used to push the multiple supporting mechanisms 3 so that the multiple supporting mechanisms 3 are distributed in a triangular shape on the front cover 2 after being pushed;

[0068] The detection mechanism 7 is installed on the side of the support mechanism 3 away from the agitator blade 15, and is used to detect the environment in which the agitator blade 15 moves forward. The detection mechanism 7 includes a plurality of positioning springs 71 fixedly installed on the side of the support rod 34 away from the agitator blade 15, and one end of the plurality of positioning springs 71 away from the support rod 34 is fixedly connected to a movable plate 72, a mounting hole is provided at the top of the support rod 34, and a pressure sensor 73 is provided at the mounting hole, and the movable plate 72 is located outside the pressure sensor 73;

[0069] A fixed plate 74 is slidably connected to the outer side of the movable plate 72, and the fixed plate 74 is fixedly installed on the support rod 34. A locking mechanism 75 is provided between the fixed plate 74 and the movable rod. A plurality of fixed cutting teeth 742 are equidistantly installed on the fixed plate 74, and a plurality of movable cutting teeth 722 are equidistantly installed on the movable plate 72. The fixed cutting teeth 742 and the movable cutting teeth 722 are staggered. At the same time, the plurality of movable cutting teeth 722 are relatively protruding under the connection of the movable plate 72, so that the movable cutting teeth 722 cooperate with the fixed cutting teeth 742 to cut the soil or weeds.

[0070] The locking mechanism 75 is arranged in the first fixed groove 721 on the side of the movable plate 72 close to the fixed plate 74, and the second fixed groove 741 is arranged on the side of the fixed plate 74 close to the movable plate 72. The first magnet 751 is installed inside the first fixed groove 721, and the second magnet 752 is installed inside the second fixed groove 741. The first magnet 751 and the second magnet 752 are magnetically connected. When in use, the movable plate 72 is mutually attracted by the first magnet 751 and the second magnet 752, so that the movable plate 72 and the fixed plate 74 remain relatively fixed.

[0071] The front cover 2 is provided with an opening at a position corresponding to the pushing mechanism 5. The pushing mechanism 5 includes a pushing block 51 that passes through the opening. Two inclined surfaces 511 are provided on one side of the pushing block 51 close to the inside of the front cover 2. The two inclined surfaces 511 make the pushing block 51 form an isosceles triangle shape. The pushing block 51 pushes the multiple supporting blocks 31 through its two inclined surfaces 511.

[0072] The push block 51 is provided with two threaded holes, and the positions of the two threaded holes are staggered with the adjacent support blocks 31;

[0073] The pushing block 51 is threadedly connected to a pushing screw rod 52 through a threaded hole. The two pushing screw rods 52 are rotatably connected to the front cover 2. A rotating mechanism 9 is installed at one end of the two pushing screw rods 52 located on the outer side of the front cover 2. The rotating mechanism 9 is used to drive the two pushing screw rods 52 synchronously. The rotating mechanism 9 enables the two pushing screw rods 52 to rotate synchronously at the front cover 2. When the two pushing screw rods 52 rotate, a driving force is provided to the pushing block 51 thereon, so that the pushing block 51 moves along the opening.

[0074] Specific implementation process: when the multiple groups of slurry knives 15 rotate with the stirring shaft 14 and the walking machine walks along the paddy field to stir the slurry, the fixed cutting teeth 742 and the mobile cutting teeth 722 located at the fixed plate 74 and the mobile plate 72 at the forward end of the multiple support rods 34 first contact the soil in the paddy field, and at the same time, the multiple fixed cutting teeth 742 and the mobile cutting teeth 722 are staggered to cut and crush the larger soil or weeds.

[0075] When one of the moving cutting teeth 722 encounters a harder stone, the moving plate 72 continues to contact the stone through the moving cutting teeth 722, resulting in a greater force on the moving plate 72. At this time, the second magnet 752 on the moving plate 72 is separated from the first magnet 751 on the fixed plate 74, and the moving plate 72 continues to move along the support rod 34 until the top of the moving plate 72 contacts the pressure sensor 73, and the controller receives a signal.

[0076] At this time, the rotating member 8 located at the front cover 2 operates, so that the positioning plate 42 drives the multiple positioning rods 41 at its bottom to separate from the multiple support blocks 31. Subsequently, the rotating mechanism 9 operates, so that the pushing block 51 moves inward along the opening. Since the pushing surface of the pushing block 51 is a triangle formed by two inclined surfaces 511, as the pushing block 51 continues to push, the multiple support blocks 31 move along the moving opening 21 respectively, until the pushing block 51 stops moving, and the multiple support blocks 31 form a triangular distribution with each other, so that the support rods 34 at their bottom form a triangular distribution, and then The plurality of support rods 34 form a diversion shape to achieve the function of diverting larger stones. As the walking machine continues to move forward, the larger stones will eventually deviate to the plurality of slurry blades 15, thereby achieving the function of avoiding obstacles for the slurry blades 15, preventing the slurry blades 15 from contacting with larger stones and being damaged, thereby ensuring the service life of the slurry blades 15. Until the signals at the pressure sensors 73 at the plurality of support rods 34 are restored to the set values, the rotating parts and the rotating parts will run in reverse in turn, so that the scraping frame 61 can continuously scrape the soil stirred to the outside through the scraping groove 611.

[0078] When the lifting screw rod 432 is driven, the motor 82 is rotated to operate, so that the first rotating gear 83 drives the second rotating gear 84 to rotate. When the second rotating gear 84 rotates, the lifting screw rod 432 connected to the second rotating gear 84 rotates. Example

[0080] Then, the electric push rod 92 is operated, so that the pushing frame 93 drives the pushing rack 94 at the bottom thereof to move relative to the two rotating gears 95. When the pushing rack 94 moves, the two rotating gears 95 respectively drive the pushing screw 52 thereon to rotate relative to the front cover 2.
