Description

Technical Field

[0001] The present invention relates to the technical field of seed drills, and in particular to a PLC-controlled film-laying, pipe-laying, and direct-insertion precision seeding all-in-one machine. Background Art

[0002] With the development of modern efficient water-saving irrigation technology, ridge cultivation and sub-film drip irrigation technology has become an important planting mode for crops in arid and semi-arid areas. In response to the application of ridge cultivation and sub-film drip irrigation technology, corresponding mechanized devices such as ridge cultivation, drip irrigation tape (drip irrigation pipe), and film covering have been developed.

[0003] In actual planting, when the seeds have germinated and the seedlings have reached the critical stage of film-breaking, the covering film must be precisely broken to ensure smooth emergence of the seedlings. However, traditional manual film-breaking operations have two major technical bottlenecks: First, in large-scale planting scenarios, breaking the film plant by plant is time-consuming and labor-intensive, resulting in low production efficiency; second, if the soil is relatively compacted, the seedbed will easily become inadequately aerated after film-covering, easily forming an oxygen-deficient microenvironment, inhibiting seed respiration and causing a decrease in seedling emergence rate. Summary of the Invention

[0004] The purpose of the present invention is to propose a PLC-controlled film-laying and pipe-laying direct-insertion precision seeding machine in order to solve the problem that the film-breaking operation for each plant is time-consuming and labor-intensive, and the production efficiency is low in large-scale planting scenarios.

[0048] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] like Figure 1 - Figure 10 As shown, the present invention provides:

[0050] The PLC-controlled film-laying and pipe-laying straight-insertion precision seeding machine includes a body 10 and a seed storage unit 20 mounted on the body 10. The body 10 includes a frame 11. The bottom of the frame 11 is rotatably connected to a transmission shaft through a first bearing seat. Wheels are fixed at both ends of the transmission shaft. An extension frame 12 is fixed to one side of the frame 11. Mounting pipes are fixed on both sides of the extension frame 12. In particular, the frame 11 can be connected to a tractor, and the frame 11 is moved by the tractor. In further detail, a PLC control element is installed on the frame 11, and the electric hydraulic push rod can be controlled by the PLC control element.

[0051] like Figure 1 、 Figure 4 、 Figure 5 and Figure 7 As shown, the seed storage unit 20 includes a seed storage box 21 fixed to the frame 11, a seed separation tube 22 is fixed to the bottom of the seed storage box 21, and a seed separation shaft 23 is rotatably connected to the seed separation tube 22. A seed feed slot connected to the seed storage box 21 is provided on one side of the seed separation tube 22, and a plurality of inoculation slots corresponding to the seed feed slots are provided on the outer wall of the seed separation shaft 23, and the inoculation slots are evenly divided into three groups. A lower seed tube 24 corresponding to the inoculation slot is fixedly connected to the other side of the seed separation tube 22. In particular, a support seat is welded to the end of the mounting rod for supporting the end of the lower seed tube 24 to ensure its stability. Preferably, a power box is also provided on the frame 11, and a battery for powering electrical components is provided in the power box.

[0052] The seeding shaft 23 passes through the seeding tube 22, and both ends thereof are sleeved with a second bearing seat. The second bearing seat is fixed to the frame 11. A linkage shaft is connected to the seeding shaft 23 by installing a third bearing seat on the upper surface of the frame 11 near the second bearing seat. A gear is fixed to one end of the linkage shaft and the seeding shaft 23, and the two gears are meshed. A sprocket is fixed on the outer surface of the transmission shaft and the linkage shaft. The two sprockets are connected together by a chain. Specifically, when the machine body 10 follows the tractor, the wheel rotates with the transmission shaft. The sprocket chain and two gears drive the seed separation shaft 23 to rotate in the seed separation tube 22. It is worth noting that the outer wall of the seed separation shaft 23 fits the inner wall of the seed separation tube 22, so that the vegetable seeds in the seed storage box 21 will not enter the seed separation tube 22. When the seed separation shaft 23 rotates, when the inoculation groove on its surface rotates to correspond to the seed feed groove, the seeds will enter the inoculation groove, and then in the process of continued rotation, when the inoculation groove that receives the seeds rotates to the position corresponding to the lower seed tube 24, it will fall into the lower seed tube 24.

[0053] like Figure 1 、 Figure 2 、 Figure 8 and Figure 10 As shown, a film laying unit 30 and a pipe laying unit 40 are connected to one side of the machine body 10 via an extension frame 12, and a direct insertion component 50 is assembled on the extension frame 12;

[0054] The plug-in assembly 50 includes a synchronous frame 52 plugged into the extension frame 12. A first electric hydraulic push rod 51 is installed in the middle of the extension frame 12, with one end connected to the synchronous frame 52.

[0055] A hole-opening member 53 and a film-breaking member 54 are respectively installed on both sides of the lower surface of the synchronous frame 52. Under the drive of the first electric hydraulic push rod 51, the hole-opening member 53 and the film-breaking member 54 can be moved downward synchronously to complete the hole-opening and the segmentation of the corresponding sowing hole positions on the surface of the laid ground film;

[0056] In further detail, the membrane breaker 54 includes a retaining rod 541 fixed to one side of the lower surface of the synchronous frame 52. The outer surface of the retaining rod 541 is provided with a sliding sleeve 542 fixed by bolts. The bottom end of the sliding sleeve 542 is threadedly connected to an outer retaining cylinder 543. The outer surface of the outer retaining cylinder 543 is slidably connected to a vertical slider via a vertical sliding groove. The end of the vertical slider extending into the outer retaining cylinder 543 is fixed with an inner retaining cylinder 544.

[0057] The other end of the vertical slider is fixed with a positioning ring 545, and a knob stud is threaded on the positioning ring 545, so that the position of the positioning ring 545 and the inner retaining cylinder 544 can be fixed after moving. Specifically, after loosening the knob stud, the fixation of the positioning ring 545 can be released. At this time, the positioning ring 545 can be adjusted by sliding it up and down. After adjustment, the knob stud is tightened again to fix the position of the positioning ring 545, so that the position of the inner retaining cylinder 544 is fixed, and the bottom ends of the outer retaining cylinder 543 and the inner retaining cylinder 544 are fixed with an annular knife 546 for cutting the ground film;

[0058] Specifically, after the outer retaining cylinder 543 and the inner retaining cylinder 544 are driven by the first electric hydraulic push rod 51 to move downward to abut against the surface of the laid ground film, the annular knife 546 can perform an annular cutting on the ground film surface above the hole, so that an annular spacing groove is formed in this part, so that the ground film above the seed can be easily lifted up to separate from the ground film body while maintaining its integrity, and then this part of the ground film can be gradually lifted up to separate from the ground film body after the vegetable seedlings grow out, without the need for subsequent manual tearing operation at the position of the vegetable seedlings in the ground film. At the same time, the annular spacing groove will also increase air permeability, avoid the ground film being laid too tightly and affecting the air permeability of the seeds, while also ensuring normal moisturizing function, and also avoiding the situation of high temperature scalding of the seedlings caused by not tearing the vegetable seedlings in time after they grow up in hot weather;

[0059] At the same time, the inner retaining tube 544 can move up and down following the positioning ring 545, so that its bottom end can be flush with the bottom end of the outer retaining tube 543, lower than the bottom end of the outer retaining tube 543, or higher than the bottom end of the outer retaining tube 543, thereby making the annular knife 546 at the bottom end of the outer retaining tube 543 and the inner retaining tube 544 respectively exposed or kept horizontal, thereby realizing the formation of large-circle annular spacing grooves, small-circle annular spacing grooves, or large-circle spacing grooves and large-circle spacing grooves at the same time on the ground film above the hole according to the planting needs;

[0060] It is worth noting that when it is necessary to open a small annular spacing groove, it is necessary to adjust the bottom end of the inner retaining cylinder 544 to be lower than the bottom end of the outer retaining cylinder 543, then loosen the bolts, release the restriction on the sliding sleeve 542, and then move the sliding sleeve 542 upward to allow the outer retaining cylinder 543 to move upward with the inner retaining cylinder 544. When the annular knife 546 that has moved to the bottom end of the inner retaining cylinder 544 moves up to the same plane as the annular knife 546 at the bottom end of the outer retaining cylinder 543 in the initial state, it stops. At this time, tighten the bolts again to re-fix the sliding sleeve 542. In this state, when the synchronous frame 52 moves downward, only the annular knife 546 at the bottom end of the inner retaining cylinder 544 can contact the ground film, thereby cutting out the small annular spacing groove;

[0061] In particular, when a large annular spacing groove needs to be opened, the position of the sliding sleeve 542 remains unchanged, and only after the knob screw is loosened, the inner retaining cylinder 544 is moved upward by the positioning ring 545, so that the annular knife 546 at the bottom end of the inner retaining cylinder 544 is completely immersed in the outer retaining cylinder 543. At this time, when the synchronous frame 52 moves downward, only the annular knife 546 at the bottom end of the outer retaining cylinder 543 can contact the ground film, thereby cutting a large annular spacing groove;

[0062] At the same time, when it is necessary to open the large and small circle spacing grooves at the same time, it is sufficient to maintain the initial state of the outer retaining cylinder 543 and the inner retaining cylinder 544. In this state, the bottom ends of the outer retaining cylinder 543 and the inner retaining cylinder 544 are on the same horizontal plane.

[0063] like Figure 1 、 Figure 4 、 Figure 6 and Figure 10 As shown in further detail, the hole-opening member 53 includes a hollow tube 531 fixed to the other side of the lower surface of the synchronous frame 52, and a hollow hole-opening head 532 is fixed to the bottom end of the hollow tube 531. Specifically, during the downward movement of the synchronous frame 52, the hollow hole-opening head 532 will synchronously descend and gradually penetrate into the soil, thereby opening holes on the soil surface for sowing vegetable seeds.

[0064] A drop groove is formed on one side of the hollow hole-opening head 532, and a slot sealing door 533 is hinged on the inner wall of the drop groove via a spring hinge. A second electric hydraulic push rod 534 is assembled on one side of the upper surface of the synchronization frame 52. A linkage plate 535 is fixed to one end of the second electric hydraulic push rod 534. A pull rope 536 is fixed to the lower surface of the linkage plate 535. A guide tube for guiding the pull rope 536 is fixed to the outer wall of the hollow tube 531 and the hollow hole-opening head 532. The pull rope 536 passes through one end of the guide tube and is connected to the slot sealing door 533.

[0065] Specifically, when the hole is opened, the first electric hydraulic push rod 51 drives the synchronous frame 52 and the hollow hole opening head 532 to move upward, and the second electric hydraulic push rod 534 drives the linkage plate 535 to move downward. At this time, the top of the pull rope 536 is driven to move downward together, and then the bottom end of the pull rope 536 moves upward, thereby driving the sealing slot door 533 to rotate upward, so that the drop slot is opened, and the seeds in the hollow hole opening head 532 can fall into the hole. After the hollow hole opening head 532 moves up to the initial state, the second electric hydraulic push rod 534 drives the linkage plate 535 to move up and reset. At this time, under the action of the spring hinge, the sealing slot door 533 is gradually closed.

[0066] A holding tube is fixed to the bottom end of the seed tube 24, and the hollow tube 531 is slidably installed in the holding tube. A seeding groove connected to the seed tube 24 is opened on one side of the inner wall of the holding tube, and an inlet groove connected to the seeding groove is opened on the inner wall of the hollow tube 531. The seeds dropped into the seed tube 24 will enter the hollow tube 531 through the connected seeding groove and inlet groove, and then fall into the hollow hole opening head 532;

[0067] In further detail, the bottom of the frame 11 is also equipped with a mounting shaft, a mounting rod is fixed on the mounting shaft, and a covering piece is detachably fixed on the mounting rod. After the hole is opened by the hole opening head and seeds are sown in the hole, when the body 10 continues to move, the covering piece behind the hole opening head will drive the soil forward, thereby filling the hole and covering the seeds with soil.

[0068] like Figure 1 、 Figure 6 and Figure 9 As shown, the pipe laying unit 40 includes a front mounting plate 41 fixed on the inner wall of the extension frame 12, and a front retaining plate 42 is detachably fixed on the front mounting plate 41, and a front rotating rod 43 for placing the drip irrigation pipe is rotatably connected in the front retaining plate 42, and a limit plate 44 for limiting the position of the drip irrigation pipe is fixedly sleeved on the front rotating rod 43, and the bottom end of the front mounting plate 41 is rotatably connected to the front guide rod. Specifically, during actual laying, one end of the drip irrigation pipe is first pulled out and fixed to the front end of the planting ridge, and then the wound drip irrigation pipe is gradually unwound during the movement of the machine body 10, and then laid under the ground film, and the front guide rod is used to guide the drip irrigation pipe to under the ground film in this process.

[0069] like Figure 1 and Figure 5 As shown, the film laying unit 30 includes a rear mounting plate fixed to the extension frame 12, a rear holding plate detachably fixed to the rear mounting plate, the rear holding plate is rotatably connected to a rear rotating rod for placing the ground film, the bottom end of the rear mounting plate is rotatably connected to a rear guide rod, and a tail mounting plate is fixed to the inner wall of the extension frame 12 on the side close to the rear mounting plate, the bottom end of the tail mounting plate is rotatably connected to a tail guide rod for keeping the laid ground film horizontal. Specifically, after one end of the drip irrigation pipe is fixed, one end of the ground film is pulled out and covered on the surface of the drip irrigation pipe, and then the end is fixed to the front end of the planting ridge. At this time, the machine body 10 is driven by the tractor to walk on the soil surface, thereby laying the ground film above the drip irrigation pipe;

[0070] In order to fix the position of the laid ground film, a vertical shaft is detachably fixed in the installation tube, and a tail plow 13 is fixed to the bottom end of the vertical shaft. Specifically, during the film laying process, the tail plow 13 at the tail of the extension frame 12 can turn the soil close to both sides of the ground film toward the ground film, and cover the two sides of the ground film with soil, so that the position of the laid ground film is fixed to prevent movement.

[0071] Specifically, when this PLC-controlled film-laying and pipe-laying direct-insertion precision seeding machine is working / in use:

[0072] 1. Device connection and startup

[0073] Step 1.1: Connect the frame 11 to the tractor and use the battery (on the frame 11) to power the PLC control components and other equipment;

[0074] Step 1.2: Calibrate the initial positions of the first electro-hydraulic push rod 51 and the second electro-hydraulic push rod 534 through the PLC control element to set the sowing spacing parameters.

[0075] 2. Preparation for pipe laying and film laying

[0076] Step 2.1: Install the drip irrigation pipe wound into a coil onto the front rotating rod 43 and clamp it with the limit plate 44; and install the ground film roll onto the rear rotating rod;

[0077] Step 2.2: Pull out one end of the drip irrigation pipe and fix it to the front end of the planting ridge. Cover the mulch end on the surface of the drip irrigation pipe and fix it.

[0078] 3. Synchronous film and pipe laying operations

[0079] Step 3.1: When the tractor pulls the machine body 10 forward, the transmission shaft drives the sprocket chain system, which in turn drives the seeding shaft 23 to rotate and seed;

[0080] Step 3.2: The front guide rod of the pipe laying unit 40 guides the drip irrigation pipe to be laid under the ground film, and the rear guide rod of the film laying unit 30 cooperates with the tail guide rod to lay the ground film flat and keep it level;

[0081] Step 3.3: During the mobile film laying process, the tail plow 13 turns over the soil to cover both sides of the film and fix the position of the film.

[0082] 4. Precision sowing and membrane breaking and hole opening

[0083] Step 4.1: When the seed separation shaft 23 rotates, the seeding slot obtains the seed through the seed feeding slot, transfers to the seed lowering tube 24, and then falls into the hollow tube 531, and finally enters the hollow hole opening head 532;

[0084] Step 4.2: The first electric hydraulic push rod 51 drives the synchronous frame 52 to move downward, and the hollow hole-opening head 532 is directly inserted into the soil to open a hole. The annular knife 546 of the film-breaking member 54 cuts the ground film laid behind to form a spacing groove;

[0085] Step 4.3: During sowing, the second electric hydraulic push rod 534 pushes the linkage plate 535 to pull down the pull rope 536, and the spring hinge opens the sealing slot door 533, and the seeds fall into the holes.

[0086] 5. Covering and equipment reset

[0087] Step 5.1: The machine body 10 continues to move forward, and the soil covering member backfills the soil into the hole to cover the seeds;

[0088] Step 5.2: The first electric hydraulic push rod 51 lifts the synchronous frame 52 to reset, and the sealing slot door 533 is closed under the action of the spring lotus leaf, completing a single sowing cycle.

[0089] 6. Adjustment of membrane rupture parameters (as needed)

[0090] Step 6.1: When adjusting the membrane breaker 54, loosen the knob stud to move the positioning ring 545, change the position of the inner retaining cylinder 544, and realize the switching of the large / small circle interval groove.

[0091] Step 6.2: If small circle cutting is required, the sliding sleeve 542 needs to be moved upward to allow the inner retaining cylinder 544 to act alone.
