Abstract
Description
Technical Field
[0001] This utility model relates to the field of film-covered seeders, and in particular to a hoe-type seeding head for film-covered seeders. Background Technology
[0002] In mulching technology, plastic film mulching effectively conserves moisture, increases soil temperature, and suppresses weeds, significantly improving crop yield and quality. Hole sowing is a crucial step in mulching, requiring precise hole making on the film and seeding into the holes. Current technologies often involve separate steps for mulching and sowing, or the use of complex combined seeders. Separate operations are inefficient, manual hole making is labor-intensive and lacks precision; existing mulching hole sowing machines often suffer from complex structures in their hole-making and sowing components, leading to large-area tearing and damage to the film during hole making, inaccurate sowing positions, and low reliability. In particular, they struggle to effectively prevent soil or film fragments from backfilling the holes during hole making, affecting sowing quality. Therefore, there is an urgent need for a high-efficiency mulching hole sowing head with a relatively simple structure, precise and reliable hole making, effective protection of the film's integrity, and the ability to link hole making and sowing in a coordinated manner. Utility Model Content
[0003] The purpose of this invention is to provide a hoe-type hole-opening and seeding head for a film-covered seeding machine to solve the above-mentioned problems.
[0004] According to one aspect of this utility model, a hoe-type hole-opening seeding head for a mulching seeder is provided, comprising: a mulching seeder having a lifting end, the lifting end being provided with a duck head, the duck head including: a duckbill mounting seat having a seed guide interface at its upper end; a duckbill including two opening and closing blocks, the upper parts of the opening and closing blocks being rotatably connected to the lower sides of the duckbill mounting seat, the upper parts of the two opening and closing blocks being provided with mutually meshing teeth, and a return spring connecting the duckbill mounting seat and one side of the opening and closing block, so that the two opening and closing blocks are in a closed state when stationary; the two opening and closing blocks are connected by a return spring. The machine is equipped with a seed storage chamber; the seed guide interface is connected to the seed storage chamber; the opening needle is located at the lower part of each opening and closing block, and the opening needles on both sides combine to form a spike when the duckbill is closed; the opening and closing rod is fixed to one side of the opening and closing block; the opening and closing steel wire rope is fixed at one end to the mulch-covered seeder and at the other end to the opening and closing rod; when the lifting end descends, the spike pierces the mulch film, and at the same time, the opening and closing steel wire rope drives the duckbill to open, and the seeds in the seed storage chamber fall under the action of gravity; after sowing is completed, when the lifting end rises, the reset spring pulls the duckbill to close.
[0005] In some embodiments, the opposite surfaces of the two opening and closing blocks are respectively provided with arc-shaped grooves, and when the two opening and closing blocks are closed, the arc-shaped grooves on both sides form the seed storage cavity.
[0006] In some embodiments, a return spring is connected between the rear left side of the duckbill mount and the opening / closing block located on the right side, so that when at rest, the opening / closing blocks on both sides are in a closed state due to the toothed structure.
[0007] In some embodiments, the outer surface of the opening and closing block is a sloped structure, and the acupuncture needle is disposed on the sloped surface.
[0008] Compared with the prior art, the beneficial effects of this application are as follows:
[0009] 1. Integrated precision operation: Through the single up and down movement of the lifting end, the complete action cycle of film piercing, hole opening (using the hole opening needle to open and form a regional groove), sowing (the seed storage chamber opens to release seeds) and resetting and closing is realized simultaneously. The structure is ingenious and the operation is reliable, which significantly improves the sowing efficiency and precision.
[0010] 2. Protect the integrity of the mulch film: When the duckbill closes, the sharp part formed can accurately pierce the mulch film. When the opening block opens, the opening needle is used to appropriately open the pierced hole to form a regional groove, which avoids large-area tearing and damage to the mulch film and protects the mulching effect to the greatest extent.
[0011] 3. Precise sowing position: The seeds are stored in the seed storage cavity formed by the opening and closing blocks. The opening action (duckbill opening) and the sowing action (seed release) are directly linked and occur at the same position, ensuring that the seeds fall accurately into the soil holes under the film formed by the opening needle.
[0012] 4. High-efficiency continuous operation: The reset spring ensures that the duckbill closes quickly and reliably after sowing, preparing for the next sowing, ensuring the smooth operation of the machine continuously and efficiently. The overall structure is relatively simple, easy to maintain, and highly practical. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] refer to Figures 1 to 3 This application provides a hoe-type hole-opening seeding head for a mulching seeder, comprising: a mulching seeder with a lifting end, the lifting end being provided with a duck head, the duck head including: a duckbill mounting base 21, the upper end of which is provided with a seed guide interface 22; a duckbill 23, including two opening and closing blocks 231, the upper part of the opening and closing blocks 231 being rotatably connected to the lower two sides of the duckbill mounting base 21, the upper parts of the two opening and closing blocks 231 being provided with mutually meshing teeth 232, a return spring connecting the duckbill mounting base 21 and one side of the opening and closing block 231, so that the two opening and closing blocks 231 are in a closed state when stationary; a seed storage cavity 2 is provided between the two opening and closing blocks 231. 35; The seed guide interface 22 is connected to the seed storage chamber 235; the opening needle 24 is set at the lower part of each opening block 231, and the opening needles 24 on both sides combine to form the spike part 241 when the duckbill 23 is closed; the opening rod 25 is fixed to the opening block 231 on one side; the opening and closing steel wire rope (not shown in the figure) is fixed at one end to the mulching seeder and at the other end to the opening and closing rod 25; when the lifting end descends, the spike part 241 pierces the mulch film, and at the same time, the opening and closing steel wire rope drives the duckbill 23 to open, and the seeds in the seed storage chamber 235 fall under the action of gravity; after sowing is completed, when the lifting end rises, the reset spring pulls the duckbill 23 to close.
[0018] In this embodiment, the lifting end of the film-covered seeding machine can be a lifting motor or a cylinder, etc., whose main function is to drive the duck head to move up and down.
[0019] The film-covered seeder in this embodiment has a seed bin, which will release a certain amount of seeds into the seed guide interface 22 at regular intervals; or seeds can be manually released into the seed guide interface 22.
[0020] The shape of the acupoint opening needle 24 can be changed according to actual needs; in this embodiment, the acupoint opening needle 24 is thin and suitable for opening holes in paddy fields to reduce mud adhesion; for dry fields, the acupoint opening needle 24 is wide.
[0021] In some embodiments, the opposite surfaces of the two opening and closing blocks 231 are respectively provided with arc-shaped grooves 234, and when the two opening and closing blocks 231 are closed, the arc-shaped grooves 234 form a seed storage cavity 235.
[0022] In some embodiments, a return spring is connected between the rear left side of the duckbill mount 21 and the opening / closing block 231 located on the right side, so that when at rest, the opening / closing blocks 231 on both sides are in a closed state due to the tooth structure.
[0023] In some embodiments, the outer surface of the opening and closing block 231 is a sloping structure, and the acupuncture needle 24 is disposed on the sloping surface.
[0024] Sowing action phase:
[0025] When the duck's head descends to its lowest position, the spike 241 of the opening needle 24 pierces the plastic film. At this time, the opening rod 25 is pulled by the opening and closing steel wire rope, forcing one side of the opening block 231 to rotate around the axis of the duck's beak mounting base 21; due to the meshing teeth on the upper part of the opening block 231 meshing with each other, the other side of the opening block 231 rotates synchronously in the opposite direction, realizing the symmetrical opening of the duck's beak 23. The seeds in the seed storage cavity 235 fall into the soil under the film under the action of gravity, while the opening needles 24 on both sides expand obliquely outward, expanding the piercing hole into a regular round hole (to prevent the film from tearing).
[0026] Reset phase:
[0027] The duck's head rises as a whole, and at the same time the opening and closing steel wire rope loosens. The duck's beak 23 closes under the action of the reset spring, preparing for the next seed supply from the seed-guiding interface 22.
[0028] Integrated precision operation: Through the single up and down movement of the lifting end, the complete action cycle of film piercing, hole opening (using the opening needle 24 to open to form a regional groove), sowing (the seed storage chamber 235 opens to release seeds) and resetting and closing is realized simultaneously. The structure is ingenious and the operation is reliable, which significantly improves the sowing efficiency and precision.
[0029] Protecting the integrity of the mulch film: When the duckbill 23 is closed, the spike 241 formed can accurately pierce the mulch film. When the opening block 231 is opened, the hole opening needle 24 is used to appropriately open the pierced hole to form a regional groove, which avoids large-area tearing and damage to the mulch film and protects the mulching effect to the greatest extent.
[0030] Precise sowing location: The seeds are stored in the seed storage cavity 235 formed by the opening and closing block 231. The opening action (the duckbill 23 opens) and the sowing action (seed release) are directly linked and occur at the same location, ensuring that the seeds fall accurately into the soil holes under the film formed by the opening needle 24.
[0031] High-efficiency continuous operation: The reset spring ensures that the duckbill 23 closes quickly and reliably after sowing, preparing for the next sowing, ensuring the smooth operation of the machine continuously and efficiently. The overall structure is relatively simple, easy to maintain, and highly practical.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
