Description

Technical Field

[0001] The present invention relates to the technical field of seed planting, and specifically to an agricultural plastic film machine for agricultural mechanization. Background Art

[0002] In agricultural production, repairing ridges, planting seeds, and covering with plastic film are key links to ensure high yields and high quality of crops. By repairing ridges, the soil structure is optimized, the water and fertilizer retention capacity is improved, providing a good growth environment for seeds. And when sowing seeds, through precise sowing, the seed germination rate and the uniformity of seedling emergence are improved. Finally, through the plastic film covering operation, the soil temperature is increased, moisture is retained, weeds are inhibited, and seed germination is promoted.

[0003] Currently, in the existing process of seed planting, it is necessary to repair the ridges. After planting the seeds on the ridges, then cover with plastic film. However, during the process of covering with plastic film, for the existing plastic film machines, a roll of plastic film is installed on the plastic film machine, and the plastic film machine is connected to a traction device. By manually controlling the movement of the traction device, the plastic film is covered on the planted ridges. When the plastic film machine continuously moves to the end of the ridge, and then when it is necessary to cover the next ridge, the plastic film cannot be detached from the position of the previous ridge in time, resulting in pulling of the protective film, further affecting the covering of the subsequent ridges. For this reason, we propose an agricultural plastic film machine for agricultural mechanization. Summary of the Invention

The other end of the support spring 412 is fixedly connected to the support rod 413. The support rod 413 slidably penetrates through the bottom of the support sleeve 411, and the bottom of the support rod 413 is fixedly connected to the disconnection block 42. In this embodiment, when the disconnection block 42 is not affected by external forces, the support spring 412 is used to support the support rod 413, and through the support rod 413, the disconnection block 42 is located above the laid plastic film, so that the disconnection block 42 does not affect the laid plastic film;

[0049] Please refer to Figures 9 to 12 , the soil burying member 43 includes a rotating shaft 431, a closing plate 432, a rotating member 433, a driving motor 434 and a spiral blade 435. The rotating shaft 431 is rotatably connected to the top of the opening 423, and the closing plate 432 is fixedly sleeved on the rotating shaft 431. The closing plate 432 is located at the opening 423. One end of the rotating shaft 431 outside the disconnection block 42 is connected to the rotating member 433. The driving motor 434 is installed inside the inlet groove 422, and the rotating motor is used to drive the spiral blade 435. One end of the spiral blade 435 extends to the outside of one end of the inlet groove 422;

[0050] One end of the spiral blade 435 extends to the outside of the disconnection block 42, so that while the disconnection block 42 is inserted into the soil, the spiral blade 435 can introduce the external soil into the inlet groove 422;

[0051] The rotating member 433 includes a worm gear 4331, a worm 4332, a first rotating gear 4333, a second rotating gear 4334, a guiding rack 4335 and an extension plate 4336. The worm gear 4331 is fixedly installed at one end of the rotating shaft 431 outside the disconnection block 42, and the worm gear 4331 is meshed with the worm 4332. The worm 4332 is rotatably connected to the outside of the disconnection block 42. One end of the worm 4332 is fixedly connected to the first rotating gear 4333, and the second rotating gear 4334 is meshed with the first rotating gear 4333. The second rotating gear 4334 is rotatably connected to the outside of the disconnection block 42 through a rotating shaft. The extension plate 4336 is fixedly installed on the whole machine bracket 1, and the guiding rack 4335 is fixedly connected to the extension plate 4336. The guiding rack 4335 is used to drive the second rotating gear 4334;

[0052] Specific implementation process: When the seeds on the ridge are planted, and after the plastic film is covered on the ridge through the traction device, and when the plastic film moves to the end of the ridge, the operator sits on the seat plate of the whole machine bracket 1 and steps on the foot pedal starting mechanism 5, so that the support block 44 drives the disconnection block 42 to move down along above the plastic film, and during the downward movement of the disconnection block 42;

[0053] First, the second rotating gear 4334 contacts the guiding rack 4335, and at the same time, the second rotating gear 4334 meshes with the guiding rack 4335. Further, the second rotating gear 4334 rotates relative to the guiding rack 4335, then the first rotating gear 4333 rotates synchronously. When the first rotating gear 4333 rotates, the worm 4332 drives the worm wheel 4331 to rotate, so that the rotating shaft 431 drives the closing plate 432 to rotate. Until the second rotating rack moves down and disengages from the guiding rack 4335, at this time, the closing plate 432 rotates 90°, and the closing plate 432 maintains the state of closing the opening 423. At the same time, under the limiting state of the closing plate 432, the inlet groove 422 forms a circular shape;

[0054] Subsequently, as the disconnecting block 42 continues to move down, the disconnecting block 42 cuts the plastic film at the end of the ridge. At the same time, the inlet groove 422 of the cutting block moves into the soil. At this time, the rotating motor operates, so that the spiral blade 435 rotates. When the spiral blade 435 rotates, the soil is guided into the inlet groove 422;

[0055] After the disconnecting block 42 cuts the plastic film, the disconnecting block 42 moves up. As the disconnecting block 42 moves up, the closing plate 432 opens again. And through the rotation of the rotating motor, the soil inside the inlet groove 422 slides obliquely onto the plastic film at the end of the ridge under the open state of the opening 423, so that the soil covers the plastic film.

[0056] A foot-operated starting mechanism 5 is provided on the whole machine bracket 1, and the disconnecting mechanism 4 is driven manually through the foot-operated starting mechanism 5;

[0057] Please refer to Figures 4 to 6 , the foot-operated starting mechanism 5 includes a fixing frame 51, a foot pedal 52, a connecting member 53 and a moving inclined block 54. The fixing frame 51 is fixedly connected to the whole machine bracket 1. One end of the foot pedal 52 is rotatably connected to the fixing frame 51 through a pin shaft. The connecting member 53 is installed on the fixing frame 51, and the connecting member 53 is connected between the foot pedal 52 and the moving inclined block 54. The moving inclined block 54 slides through the inclined groove 441.

[0058] The connecting member 53 includes a connecting spring 531, a connecting plate 532, a first connecting seat 533, a connecting rod 534, a second connecting seat 535, a synchronous gear 536 and a synchronous rod 537. The two ends of the connecting spring 531 are fixedly connected to the foot pedal 52 and the connecting plate 532 respectively;

[0059] The first connecting seat 533 is rotationally connected to the foot pedal 52 through a pin shaft. Both ends of the connecting rod 534 are fixedly connected to the first connecting seat 533 and the second connecting seat 535 respectively. And the second connecting seat 535 is rotationally connected with two connecting support rods 538 through a pin shaft. One ends of the two connecting support rods 538 are fixedly connected to each other with a synchronous shaft 539. One end of the synchronous shaft 539 is rotationally connected to the fixed frame 51;

[0060] The synchronous gear 536 is fixedly installed on the synchronous shaft 539. And a plurality of gear grooves 5371 are equidistantly arranged on the synchronous rod 537. The synchronous gear 536 is meshed and connected with the gear grooves 5371. One end of the synchronous rod 537 passes through the fixed frame 51 and is fixedly connected to the moving inclined block 54. The synchronous rod 537 is slidably connected to the fixed frame 51;

[0061] Specific implementation process: When the seeds on the ridge are planted and, through the traction device, the plastic film is covered on the ridge and, when it moves to the end of the ridge along with the plastic film, then the operator sits on the seat board of the whole machine bracket 1 and steps on one end of the foot pedal 52. At this time, the foot pedal 52 rotates under the support of the fixed frame 51. And when the foot pedal 52 rotates, the connecting support rods 538 are pulled through the connecting rod 534 and the second connecting seat 535. And when the two connecting support rods 538 are stressed, the other ends drive the fixed shaft 81 to rotate, so that the fixed shaft 81 rotates relative to the fixed frame 51. And when the fixed shaft 81 rotates, the synchronous gear 536 rotates. And when the synchronous gear 536 rotates, the synchronous rod 537 is driven to move relative to the fixed frame 51 through the gear grooves 5371. And when the synchronous rod 537 moves, it drives the moving inclined block 54 to move along the inclined groove 441, so that the support block 44 moves downward along the plastic film, realizing the function of extruding the disconnecting block 42.

[0062] Please refer to Figures 13 to 15 , two guiding mechanisms 6 are further arranged at the bottom of the whole machine bracket 1. The two guiding mechanisms 6 synchronously guide the plastic film. The guiding mechanism 6 is connected to the foot pedal starting mechanism 5;

[0063] One end of the moving inclined block 54 far from the synchronous rod 537 is fixedly connected with a pushing plate 541. And two pushing inclined surfaces 5411 are arranged on the pushing plate 541. The pushing inclined surfaces 5411 are connected to the guiding mechanism 6;

[0064] The guiding mechanism 6 includes a guiding frame 61, a guiding member 7, a clamping and limiting member 8 and a positioning frame 9. The guiding frame 61 is fixedly installed at the bottom of the whole machine bracket 1. And the guiding member 7 slidably penetrates through the guiding frame 61. And one end of the guiding member 7 is connected to the pushing inclined surface 5411. The bottom of the guiding member 7 is connected to the clamping and limiting member 8. The clamping and limiting member 8 is connected to the positioning frame 9. And the positioning frame 9 is installed at the bottom of the whole machine bracket 1;

[0065] The clamping and limiting member 8 includes a fixed shaft 81, a torsion spring 82 and a clamping plate 83. There are two fixed shafts 81. One ends of the two fixed shafts 81 are fixedly connected to the positioning frame 9. The torsion spring 82 is sleeved outside the fixed shaft 81. Two ends of the torsion spring 82 are respectively fixedly connected to the positioning frame 9 and the clamping plate 83. The two clamping plates 83 guide and limit the plastic film relative to each other;

[0066] Specific implementation process: When pushing the inclined block to move along the direction of the support block 44, the pushing plate 541 is synchronously driven to move. At this time, the pushing plate 541 drives the two guiding mechanisms 6 to move respectively. The guiding mechanism 6 pushes one ends of the two clamping plates 83. Due to the limiting effect of the fixed shaft 81 and the torsion spring 82, the other ends of the two clamping plates 83 rotate towards each other. The other ends of the two clamping plates 83 clamp and fix the plastic film during cutting, preventing the plastic film near the unwinding roller 2 from being pulled with a large force, and further ensuring the subsequent complete film covering of the plastic film.

[0067] Embodiment Two

[0068] Embodiment Two further supplements the guiding member 7 in Embodiment One. Specifically, the guiding member 7 includes a cross bar 71, a wedge-shaped block 72, a vertical plate 73, a compression spring 74 and a tapered block 75. The cross bar 71 slides through the guiding frame 61, and one end of the cross bar 71 is fixedly connected to the wedge-shaped block 72. The wedge-shaped block 72 contacts the pushing inclined surface 5411;

[0069] The other end of the cross bar 71 is fixedly connected to the vertical plate 73, and the tapered block 75 is fixedly installed at the bottom of the vertical plate 73. The tapered block 75 abuts against one ends of the two clamping plates 83. The compression spring 74 is sleeved outside the cross bar 71, and two ends of the compression spring 74 are respectively fixedly connected to the vertical plate 73 and the guiding frame 61;

[0070] Thus, when the two pushing inclined surfaces 5411 of the pushing plate 541 move relative to the two wedge-shaped blocks 72, the two wedge-shaped blocks 72 move towards each other. When the two wedge-shaped blocks 72 move towards each other, the tapered block 75 is driven to move along one ends of the two clamping plates 83 through the cross bar 71 and the vertical plate 73, so that the other ends of the two clamping plates 83 clamp the plastic film during cutting.
