Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to an integrated machine for straw return to the field and film harvesting. Background Technology

[0002] Some crops are protected by plastic film during their growth according to environmental needs. When the new round of cultivation begins, the plastic film needs to be collected and the straw buried in the soil is returned to the field to enrich the soil.

[0003] The policy of returning straw to the field allows straw to be buried in the soil in a planned manner, releasing nutrients from the straw into the soil to enrich it. However, the current technology involves different equipment for collecting the film from the soil, crushing the straw, and returning it to the field. If the amount of straw buried is uneven, it can easily cause uneven field surfaces and a large difference in the ratio of soil to straw, which can affect crop growth and uneven seedling emergence. Summary of the Invention

[0027] Furthermore, the connecting assembly includes two spring sleeves that slide inside the sliding cover. The bottom of the spring end of the spring sleeve is fixed to the inner wall of the sliding cover. The inner wall of the spring sleeve is fitted onto the outer wall of the electric telescopic rod. The end of the electric telescopic rod away from the spring sleeve is rotatably connected to a connecting joint.

[0028] Furthermore, the limiting components include two limiting grooves opened on the side wall of the straw crusher, two rotatable arms connected to the outer wall of the straw crusher, and a fixing block fixedly connected inside the straw crusher.

[0029] Furthermore, the development component includes a rotating rod rotatably connected to the inner wall of the fixed block, two connecting arms slidably connected to the outer wall of the rotating rod, a connecting clamp rotatably connected to the outer wall of the rotating rod, and a fin-shaped development block rotatably connected to the side of the connecting clamp away from the rotating rod.

[0030] The connecting arm rotates on the outer wall of the fin-shaped development block on the side away from the rotating rod.

[0031] Furthermore, the transmission assembly includes an agitator that rotates inside the connecting joint, a spherical drive shaft that is rotatably connected to the bottom of the agitator, a spherical cavity that is opened at the top of the fin-shaped excavator, and a drive cavity that extends into the interior that is opened at the side wall of the fin-shaped excavator.

[0032] The drive cavity and the spherical cavity are connected, and the spherical drive shaft is placed inside the spherical cavity.

[0033] Furthermore, the drive assembly includes a drive shaft rotatably connected to the inner wall of the drive cavity, a protective sleeve slidably connected to the outer wall of the drive shaft, the outer wall of the drive shaft meshing with the bottom outer wall of the spherical drive shaft, a drive roller one slidably connected to the outer wall of the protective sleeve, a drive roller two slidably connected to the outer wall of the protective sleeve away from the drive roller one, and the side wall of the drive roller one being fixedly connected to the side wall of the drive roller two.

[0035] Furthermore, the leveling component includes a U-shaped connecting frame rotatably connected to the outer wall of the fin-shaped excavator block. A rotating arm is rotatably connected to the side of the U-shaped connecting frame away from the fin-shaped excavator block. A limit rod is slidably connected to the inner wall of the rotating arm away from the U-shaped connecting frame. The outer wall of the limit rod slides inside the Y-shaped leveling block.

[0036] Among them, the internal teeth of the drive roller mesh with the drive shaft near the end.

[0037] The present invention has the following beneficial effects:

[0038] 1. This invention restricts the distribution of crushed straw when returning straw to the field. After the straw is crushed by the straw crusher, the crushed straw fragments remain on the soil surface as it passes. As the front drive vehicle moves and drags the straw crusher forward, the two arms will catch the crushed straw fragments along the way. According to the internal structure, the straw fragments are gradually moved to the center and left in the space formed by the angle between the two arms. This restricts the large accumulation of crushed straw in one place and ensures that the crushed straw is dispersed in the soil to a near-uniform degree.

[0039] 2. This invention addresses the need for soil trenching and dispersion during straw return to the field. However, due to the unclear internal conditions of the soil, obstacles exist during trenching. An electric telescopic rod extends, and the contact end between the electric telescopic rod and the connecting joint generates force. This force, through a stirring grid and a spherical drive shaft, pushes the fin-shaped excavator block as a whole, causing it to rotate to a certain extent along the connection between the connecting clamp and the rotating rod. Because one end of the fin-shaped excavator block extends away from the straw crusher, this extension will preferentially touch the soil surface and penetrate the soil when pushed by the electric telescopic rod. Based on the arc surface of the fin-shaped excavator block's bottom, the soil is divided by the extension of the fin-shaped excavator block, and the continuous movement and dragging of the drive vehicle causes the soil to gradually extend and disperse along the arc surface of the fin-shaped excavator block. The drive vehicle's traction allows for relatively flexible trenching and dispersion of the soil through the fin-shaped excavator block. The soil generated during this process is dispersed to both sides by the arc surface of the fin-shaped excavator block, and a boom arm also partially intercepts and guides it into the trenches opened by the fin-shaped excavator block, avoiding large-scale excavation and reducing the number of additional equipment steps required.

[0040] 3. This invention aims to promote a more thorough integration of soil and crushed straw fragments during straw return to the field. When the device rotates to a certain extent through the extension of the electric telescopic rod, it achieves contact with the soil and opens trenches of appropriate depth as needed. When the drive rollers 2 and 1 on the side wall of the fin-shaped dredging block roll on the soil surface, the conical teeth inside the drive roller 1 drive the drive shaft. The presence of the protective sleeve effectively prevents soil from adhering to the drive shaft gear and causing blockage. Since the protective sleeve is embedded in the drive rollers 2 and 1 on both sides and restricted by the side wall of the fin-shaped dredging block, smooth transmission is ensured. The spherical drive shaft driven by the gear on the side wall of the drive shaft pulls and rotates the stirring grid. During the above process, the straw fragments and dispersed soil intercepted and restricted by the arm enter the trench and are mixed by the rotating stirring grid under the influence of the spherical drive shaft, making them more evenly mixed together. This allows the soil to better decompose the crushed straw fragments and promotes soil fertility.

[0041] 4. This invention addresses the post-stubble return treatment. Under the continuous traction of the driving vehicle, the fin-shaped dredging block is rotated to a certain extent by the extension of the electric telescopic rod. At this time, the U-shaped connecting frame connected to the fin-shaped dredging block rotates downward under the traction. However, due to the presence of the Y-shaped flat block, which is larger than the trench opened by the fin-shaped dredging block, the U-shaped connecting frame is in an inclined state. Due to the elevation difference in the field, the presence of the limiting rod can improve the elevation difference to a certain extent, making the Y-shaped flat block as close as possible to the soil surface. The soil is collected in the trench along the movement path, and the bottom plate covers the soil as flat as possible, presenting a more natural state, minimizing the impact on the soil environment, and creating conditions for soil decomposition of straw.

[0042] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The bottom of the spring end of the spring sleeve 112 is fixed to the inner wall of the sliding cover 111.

[0085] The drive cavity 224 is connected to the spherical cavity 223, and the spherical drive shaft 222 is placed inside the spherical cavity 223. The space for the drive device to operate is positioned by the connection between the spherical cavity 223 and the drive cavity 224, and the stirring grid 221 is driven by the spherical cavity 223 to mix the soil.

[0086] The drive assembly 31 includes a drive shaft 311 rotatably connected to the inner wall of the drive cavity 224, a protective sleeve 312 slidably connected to the outer wall of the drive shaft 311, the outer wall of the drive shaft 311 meshing with the bottom outer wall of the spherical drive shaft 222, a drive roller 313 slidably connected to the outer wall of the protective sleeve 312, a drive roller 314 slidably connected to the outer wall of the protective sleeve 312 away from the drive roller 313, and the side wall of the drive roller 313 and the side wall of the drive roller 314 fixedly connected.

[0087] The inner wall of drive roller 313 meshes with the side wall of drive shaft 311, and the side wall of drive roller 313 rotates on the outer wall of fin-shaped excavator 214. The side wall of drive roller 314 rotates on the outer wall of fin-shaped excavator 214. The drive roller 313 and drive roller 314 rotate on the soil to generate driving force, which drives the agitator 221 through transmission.

[0088] The leveling component 32 includes a U-shaped connecting frame 321 rotatably connected to the outer wall of the fin-shaped opening block 214. A rotating arm 322 is rotatably connected to the side of the U-shaped connecting frame 321 away from the fin-shaped opening block 214. A limiting rod 323 is slidably connected to the inner wall of the side of the rotating arm 322 away from the U-shaped connecting frame 321. The outer wall of the limiting rod 323 slides inside the Y-shaped leveling block 324.

[0089] Among them, the internal teeth of the drive roller 313 mesh with the near end of the drive shaft 311; the soil surface is collected and leveled by the bottom of the Y-shaped leveling block 324.

[0090] In a specific embodiment of the present invention, before use, the input transmission end of the film-collecting machine 14 is connected to the drive vehicle 13, and the output transmission end of the straw crusher 15 is connected to the film-collecting machine 14. Under the continuous traction of the drive vehicle 13, the bottom of the film-collecting machine 14 will be inserted into the soil. The soil will be shaken by the drive vehicle, so that the soil and the film will be separated and collected. After the straw is crushed by the straw crusher 15, the crushed straw fragments will remain on the soil surface. As the drive vehicle 13 moves forward, dragging the straw crusher 15 forward, the two arms 123 will catch the crushed straw fragments along the way. According to the internal structure, the straw fragments will gradually move to the center and be left in the space formed by the angle between the two arms 123, which limits the large amount of crushed straw to pile up in one place and disperses the crushed straw in the soil to a near uniform degree.

[0091] When straw is returned to the field, the soil needs to be trenched and dispersed. However, due to the unclear internal conditions of the soil, there are obstacles in the process of trenching. The electric telescopic rod 113 extends, and the contact end of the electric telescopic rod 113 and the connecting joint 114 exert force, which pushes the fin-shaped dredging block 214 as a whole through the stirring grid 221 and the spherical drive shaft 222. The fin-shaped dredging block 214 rotates to a certain extent along the connection between the connecting clamp 213 and the rotating rod 211. Since one end of the fin-shaped dredging block 214 extends away from the straw crusher 15, the extended part will first touch the soil when the electric telescopic rod 113 pushes it. From the surface to the interior of the soil, based on the arc surface of the bottom of the fin-shaped excavator 214, the soil is divided by the extension of the bottom of the fin-shaped excavator 214 and the driving vehicle 13 continues to move and drag, so that the soil gradually extends and disperses along the arc surface of the bottom of the fin-shaped excavator 214. The driving vehicle 13 uses the traction to grooving the soil through the fin-shaped excavator 214 to disperse the soil in a relatively flexible way. The soil generated during this process will be dispersed to both sides by the arc surface of the fin-shaped excavator 214. The boom 123 also intercepts and guides part of it into the trench opened by the fin-shaped excavator 214, avoiding large-scale excavation and reducing the number of additional equipment used in the process.

[0092] Returning straw to the field promotes a more thorough integration of the soil and the crushed straw fragments. When the device rotates to a certain extent through the extension of the electric telescopic rod 113, it achieves contact with the soil and creates trenches of appropriate depth as needed. Then, the drive rollers 314 and 313 on the sidewall of the fin-shaped excavator 214 roll on the soil surface, driving the drive shaft 311 through the conical teeth inside the drive roller 313. The protective sleeve 312 effectively prevents soil from adhering to the gears of the drive shaft 311 and causing blockage. 2. The drive rollers 214 and 313 are embedded on both sides and restricted by the side wall of the fin-shaped development block 214 to ensure smooth transmission. The spherical drive shaft 222 driven by the gear on the side wall of the drive shaft 311 pulls and rotates the stirring grid 221. During the above process, the straw fragments and scattered soil intercepted and restricted by the arm 123 enter the trench and are mixed by the stirring grid 221 rotating under the influence of the spherical drive shaft 222, so that they are mixed more evenly and the soil decomposes the broken straw fragments better, promoting the fertilization of the soil.

[0093] In the post-straw return process, under the continuous traction of the drive vehicle 13, the fin-shaped dredging block 214 is rotated to a certain extent by the extension of the electric telescopic rod 113. At this time, the U-shaped connecting frame 321, which is rotatably connected to the fin-shaped dredging block 214, rotates downward under the traction. However, due to the presence of the Y-shaped leveling block 324, which is larger than the trench opened by the fin-shaped dredging block 214, the U-shaped connecting frame 321 is in an inclined state. Due to the existence of height differences in the field, the presence of the limiting rod 323 can improve the existence of height differences to a certain extent, so that the Y-shaped leveling block 324 is as close as possible to the soil surface. On the movement path, the soil is collected in the trench, and the bottom plate covers the soil as much as possible to present a more natural state, minimizing the impact on the soil environment and creating conditions for soil decomposition of straw.
