Description

Technical Field

[0001] The invention relates to the technical field of film covering equipment, in particular to a film covering device for planting angelica seedlings. Background Art

[0002] Film mulching for crop production has become a key measure for increasing agricultural production worldwide. It improves crop yields, water utilization, and labor efficiency. The angelica cultivation process requires first creating ridges on the land, then mulching the ridges with film. Finally, planting tools are used to create holes in the film-covered ridges for transplanting.

[0003] There is a Chinese patent with authorization announcement number CN221812812U, which discloses a seedling film covering device for improving the germination rate of angelica seeds. The rolling mechanism is fixedly arranged on the inner top wall of the movable plate, and the movable plate is arranged to conflict with the film.

[0004] There is a Chinese patent application number 202510306123.6, which discloses a film covering device and film covering method for angelica seedling planting, including a supporting vertical plate, two fixed wheel frames and a rectangular tube are fixedly installed on one side of the supporting vertical plate, and the two fixed wheel frames are respectively rotatably installed with walking wheels, and a rectangular telescopic rod is slidably installed on the top of the rectangular tube.

[0005] Although the technical solution in the above patent document can achieve efficient film covering of field ridges without trampling on the ridge surface, it still has the following defects during actual use: the soil used for angelica planting is fertile and loose sandy soil, and it is not easy to use the rolling method to clean the soil before film covering, which can easily affect the air permeability of the soil. When the rake claws sweep the ridge surface, if the soil under the surface soil layer is relatively moist, the rake claws are prone to adhere to the soil and it is difficult to achieve efficient treatment of the subsequent ridge surface; when angelica is transplanted under film covering, planting tools are needed to make holes in the film. The current existing hole making method basically uses manual hole making, and the planting of angelica has certain distance requirements. It is difficult to ensure the precise gap between two adjacent plants under manual processing, which will affect the growth of the later plants and the product yield. Summary of the Invention

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] By adding an opening mechanism to the existing basic components, and then using the power generated by its auxiliary mechanism to drive the opening mechanism when the basic components are in operation, the laid ground film can be synchronously marked with opening marks and pigments, thereby providing multiple reminders to the staff and ensuring accurate hole opening during artificial planting.

[0032] When the auxiliary mechanism moves, the power generated by it drives the cam in the opening mechanism to move. The cam and the contact assembly contact each other. When the cam moves, the contact assembly drives the pressure plate to press down. The downward movement of the pressure plate causes the opening assembly assembled thereon to move, compressing the return spring. The cross tool in the opening assembly moves downward to open the laid ground film, and the downward movement of the pressure plate also simultaneously compresses the pigment piece to make it spray, further realizing the marking of the opening position, making it convenient for the staff to transplant plants through the holes.

[0033] After the short axis surface of the cam contacts the contact assembly, the pressure plate in the opening mechanism is reset and moved upward under the action of the reset spring, and then the knocking rod group located on the pressure plate knocks and vibrates the box in the soil covering mechanism, further improving the unloading effect of the soil inside it.

[0034] The sealing parts in the covering mechanism and the auxiliary mechanism are meshed with each other in the form of a worm gear. When the basic components move, the sealing parts in the covering mechanism perform intermittent opening and closing movements, so that the soil in the box is intermittently released to the laid ground film, and the released soil replaces the manually spread soil belt, which reduces the burden of manual operation while ensuring the stability of the laid ground film. The intermittent unloading of soil can avoid the rapid consumption of soil in the box, reduce the frequency of manual soil release into the interior of the box, and further reduce the burden on the staff.

[0035] The base components are equipped with bulldozers that can be raised and lowered. During the movement of the base components, the ridge surface is first flattened to prevent large clods of soil on the ridge surface from damaging the mulch during laying. This ensures the flatness of the ridge surface and further ensures the safety of mulch laying. The scraping and pushing method of the bulldozers can greatly avoid the adhesion of wet soil and ensure the continuity of product use. BRIEF DESCRIPTION OF THE DRAWINGS

The eccentric wheel 9245 is arranged at the top of the rotating shaft 9243 and is in movable contact with the fixed plate. When the spiral sleeve 88 moves, the worm gear 9244 is synchronously driven to move. Since the movement between the spiral sleeve 88 and the worm gear 9244 is a deceleration movement, the rotating shaft 9243 drives the eccentric wheel 9245 to drive the sealing plate 9241 to adjust and realize intermittent delivery of soil, which not only avoids the manual soil belt operation in the later stage, but also reduces the loss of soil in the box 911, avoids frequent manual addition of soil to the box 911, and reduces the manual burden.

[0075] The working principle of the present invention is as follows: before using the product, the ground is first ridged. The product is then assembled with the traction equipment using connecting bolts and splicing components 2. Once the product and traction equipment are assembled, the entire roll of mulch film is loaded onto the film unwinding mechanism 6. After the film is assembled, it is unwound and pre-laid. Soil is then excavated from the field and placed in the box 911 of the temporary storage assembly 91 in the soil covering mechanism 9 for temporary storage.

[0076] After pre-laying the ground film, the lateral spacing between the two opening components 84 in the opening mechanism 8 is adjusted based on the current transplant spacing requirements. By adjusting the fastening bolts, the opening component 84 can be moved laterally on the carrier plate 812. Once it has moved to the appropriate position, the fastening bolts can be adjusted again to lock the carrier arms 841 in the opening component 84 with the carrier plate 812. Next, the height of the soil covering plow body 44 in the auxiliary mechanism 4 is adjusted to enable it to scrape the soil in the field furrow.

[0077] Finally, the bulldozer 7 is raised and lowered so that the bottom of the arc-shaped bulldozer plate 71 is slightly higher than the ridge surface, thereby completing the preparation work.

[0078] After preparations are complete, the traction equipment is activated, moving the entire product. As the product moves, its pusher 7 scrapes and cleans the ridge surface along the direction of travel, preventing soil clods from damaging the subsequently laid mulch. As the pusher 7 moves, scraped soil clods fall from the sides of the curved pusher plates 71 into the field ditch, ensuring the smoothness of the ridge surface.

[0079] As the product moves with the traction equipment, the auxiliary wheels 42 in the auxiliary mechanism 4 move accordingly, thereby rolling the edge of the ground film. After the edge of the ground film is rolled by the auxiliary wheels 42, the ground film roll loaded on the film unwinding mechanism 6 is unwound from the wound state, thereby ensuring the continuity of the ground film laying.

[0080] When the product moves with the traction equipment, the soil covering plow body 44 in the auxiliary mechanism 4 also moves, thereby covering the soil in the field ditch onto the compacted ground film, thereby achieving soil covering and fixing of the ground film.

[0081] While the traction device is moving, each crusher main body 923 in the soil covering mechanism 9 is started by the external controller main body. The operation of the two crusher main bodies 923 can crush the soil discharged in the box body 911.

[0082] When the product moves, the rotation of the auxiliary wheel 42 in the auxiliary mechanism 4, driven by the transmission element, causes the cam 87 and the volute sleeve 88 on it to move synchronously. As the cam 87 rotates, it rolls against the ball bearings on the curved rod 892 in the contact assembly 89. When the protruding portion of the cam 87 contacts the ball bearings, it applies force to the ball bearings, causing the curved rod 892 to move backward. As the curved rod 892 moves, it applies force to the vertical plate 894 via the U-shaped member 893, causing the pressure plate 82 to move downward. This downward movement of the pressure plate 82 simultaneously drives the lifting rods 843 in each opening assembly 84 downward, compressing the corresponding return springs.

[0083] As lift rod 843 moves downward, the cross cutter 844 at its bottom moves downward with it. As it moves downward, cross cutter 844 passes over cleaning element 842. Then, when pressure plate 82 reaches its maximum downward range, the bottom end of cross cutter 844 passes through cleaning element 842 and opens the already laid ground film. Due to the rotation of cam 87, cross cutter 844 loses its downward pressure after opening the ground film. Pressure plate 82, acting as a return spring, quickly moves upward and resets, preventing any subsequent ground film laying from being affected.

[0084] When the pressing plate 82 moves downward, it not only drives the knocking rod group 83 to move downward, but also presses the pressing pump head of the pigment piece 810, so that the pigment in the pigment piece 810 is sprayed on the laid ground film, thereby serving as a mark.

[0085] When the pressing plate 82 moves upward to reset, the knocking rod group 83 will knock and vibrate the bottom of the box 911 of the temporary storage component 91 in the soil covering mechanism 9 during the upward movement, so that the soil in the box 911 moves toward the discharge port.

[0086] As the drive shaft 85 in the transmission assembly moves with the auxiliary mechanism 4, it also synchronously rotates the volute sleeve 88. The volute sleeve 88 meshes with the worm gear 9244 of the blocking member 924 in the discharge assembly 92, in turn driving the rotating shaft 9243 to rotate. As the rotating shaft 9243 rotates, the eccentric wheel 9245 on it rotates accordingly. As the eccentric wheel 9245 moves, it contacts the fixed plate on the blocking plate 9241. When the raised portion of the eccentric wheel 9245 contacts the fixed plate, the blocking plate 9241 moves forward. When the passageway in the blocking plate 9241 coincides with the passageway areas on both sides of the guide plate 922 in the discharge hopper 921, the crushed soil rapidly falls due to gravity and the vibration of the product. The falling soil directly accumulates on the laid ground film, further compacting the film and ensuring its stability.

[0087] As the product moves, the ground film is continuously laid, and the opening mechanism 8 and the covering mechanism 9 circulate back and forth under the action of the auxiliary mechanism 4, thereby ensuring the orderly opening and center stacking of the ground film.

[0088] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
