Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a seedling arrangement trenching planting device and its working method. Background Technology

[0002] Eggplant is rich in nutrients and has multiple benefits. With the expansion of harvest area and the improvement of planting techniques, global eggplant yield and yield per unit area have been continuously increasing. However, outdated manual labor methods in the planting process have constrained the development of eggplant cultivation. To address the problems of increased labor load and intensity under these circumstances, and to achieve the goal of saving time and labor in eggplant cultivation, a mechanical device for eggplant seedling planting is proposed. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a seedling arrangement trenching planting device and its working method, which can realize the automated planting of seedlings such as eggplant seedlings.

[0004] Technical solution: To achieve the above objectives, the present invention provides a seedling arrangement trenching planting device, comprising a vehicle body, with seedling lowering slides respectively provided on both sides of the vehicle body; a seedling supply mechanism on the vehicle body, which feeds seedlings into the seedling lowering slides, after which the seedlings slide down to the planting position along the seedling lowering slides; the vehicle body is also provided with an adjusting track and an adjusting mechanism, the lower end of the seedling lowering slides is provided on a sliding seat of the adjusting track, and the adjusting mechanism can drive the sliding seat to slide on the adjusting track to change the outlet distance of the seedling lowering slides on both sides.

[0005] Furthermore, the seedling lowering slide is a pipe structure with a certain degree of elasticity. When the sliding seat slides on the adjusting track, the seedling lowering slide can adapt to deformation. The lower end of the seedling lowering slide near the slide outlet is a suspended section, on which a counterweight is installed. When the suspended section slides back and forth on the adjusting track with the sliding seat, the counterweight swings. Under the inertia of the swinging counterweight, the suspended section of the seedling lowering slide deforms and narrows to prevent the seedlings from passing through the narrowed suspended section.

[0006] Furthermore, two counterweights are arranged opposite each other on the suspended section, and the line connecting the two counterweights is consistent with the extension direction of the adjustment track.

[0007] Furthermore, the counterweight is disposed on the outer wall of the suspended section of the seedling lowering slide, and the counterweight is disposed near the slide outlet of the seedling lowering slide.

[0008] Furthermore, the seedling supply mechanism includes two sets of ring chains, which supply seedlings to the seedling discharge channels on both sides respectively; several seedling buckets are set on the ring chains, and when the ring chains rotate, each seedling bucket is alternately sent to the top opening opposite the seedling discharge channel, so that the seedlings in the seedling buckets can fall into the seedling discharge channel.

[0009] Furthermore, the two sets of ring chains are arranged one after the other on the vehicle body, and the seedling unloading slides on both sides are deformed to adapt to the two sets of ring chains, so that the shapes of the seedling unloading slides on both sides are different.

[0010] Furthermore, the adjustment mechanism includes a central rotating rod, with both ends of the central rotating rod connected to sliding seats on both sides via connecting rods. When the central rotating rod rotates, it drives the sliding seats on both sides to slide synchronously.

[0011] Furthermore, the sliding seat is equipped with a furrow opener and a soil covering device, which are located on the front and rear sides of the lower end outlet of the seedling chute, respectively; the seedlings sliding out of the seedling chute fall into the planting furrow dug by the furrow opener, and the soil covering device covers the seedlings in the planting furrow with soil.

[0012] Furthermore, a nozzle is provided on the sliding seat, and a water tank and water pipe for supplying water to the nozzle are provided on the vehicle body; the nozzle is located on the rear side of the soil covering device to spray water onto the seedlings after soil covering.

[0013] A method for operating a seedling arrangement trenching planting device includes the following steps: Step S1: Loading seedlings into seedling buckets on two sets of chain rings, and presetting the seedling exit positions of the seedling lowering slides on the adjusting track on both sides; Step S2: Moving the vehicle forward, the chain rings rotate, sending the seedlings to the seedling lowering slides; simultaneously, the central rotating rod rotates back and forth, causing the sliding seats on both sides to move back and forth around their respective seedling exit positions, causing the seedling lowering slides to sway and swing the counterweights, narrowing the suspended section of the seedling lowering slides; Step S3: The seedling buckets move with the chain rings to the seedling lowering slides. After the top openings are aligned, the seedlings in the seedling bucket fall into the seedling chute and slide down along the swaying chute. The seedlings stop sliding down after reaching the narrowed suspended section. Step S4: The central rotating rod stops rotating, so that the sliding seat stops at the seedling position on the adjusting track. The counterweight stops swinging, and the suspended section returns to its narrowed state. The seedlings in the seedling chute on both sides fall simultaneously into the planting trenches dug by the trench openers on both sides. Then, the soil covering device covers the seedlings in the planting trenches with soil, and the nozzle sprays water onto the seedlings after soil covering. Then, return to step S2 to start the next round of seedling planting.

[0014] Beneficial effects: The seedling arrangement trenching planting device and its working method of the present invention have the following beneficial effects:

[0015] 1) Through the coordination of the seedling supply mechanism and the seedling unloading chute, automated seedling planting can be achieved, saving labor.

[0016] 2) When the rotating center rod rotates, it can drive the sliding seat to slide on the adjusting track, thereby changing the exit position of the seedling slide and thus changing the planting row spacing of the seedlings.

[0017] 3) As the seedlings slide along the seedling lowering track, the sliding seat moves back and forth under the drive of the rotating central rod, causing the seedling lowering track to shake, making it less likely for the seedlings to get stuck in the seedling lowering track.

[0018] 4) There is a counterweight at the lower end of the seedling lowering slide. When the lower end of the seedling lowering slide moves back and forth with the sliding seat, the counterweight is swung, which narrows the lower end of the seedling lowering slide and prevents the seedlings from passing through. When the sliding seat stops moving, the seedlings will fall from the seedling lowering slide. This controls the seedlings in the seedling lowering slides on both sides to fall synchronously, so that the seedlings are arranged more neatly after planting. Attached Figure Description

[0022] Appendix Figure 4 This is a schematic diagram of the suspended section of the seedling lowering slide. Detailed Implementation

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] As attached Figures 1 to 4 The aforementioned seedling arrangement trenching planting device includes a vehicle body 1 with wheels underneath, allowing the vehicle body 1 to move across the soil to be planted. Seedling lowering chutes 2 are respectively installed on the left and right sides of the vehicle body 1. The seedling lowering chutes 2 are tubular, allowing the seedlings to slide down along them. A seedling supply mechanism 3 is installed on the vehicle body 1, which automatically provides seedlings to the seedling lowering chutes 2. After the seedling supply mechanism 3 delivers the seedlings into the seedling lowering chutes 2, the seedlings slide down along the chutes 2 to their planting positions on the soil.

[0025] The vehicle body 1 is also equipped with an adjustment track 4 and an adjustment mechanism 5. The adjustment track 4 is located at the bottom of the vehicle body 1, and its extension direction is perpendicular to the length direction of the vehicle body 1. Sliding seats 12 are located on the adjustment track 4, and the lower ends of the seedling lowering channels 2 on both sides are respectively mounted on two sliding seats 12. The adjustment mechanism 5 can drive the two sliding seats 12 to slide on the adjustment track 4 to change the outlet distance of the seedling lowering channels 2 on both sides, thereby changing the planting row spacing of the seedlings to meet the user's planting needs.

[0026] The seedling lowering chute 2 is a flexible pipe structure, as shown in the attached diagram. Figure 1As shown, in actual operation, the seedling lowering slide 2 is a curved pipe extending generally vertically. When the sliding seat 12 slides on the adjusting track 4, the position of the lower end of the seedling lowering slide 2 changes. Correspondingly, the seedling lowering slide 2 can adaptively deform, changing its curved shape to adapt to the change in the position of its lower end. (See attached diagram) Figure 4 As shown, the lower end of the seedling lowering slide 2, near the slide outlet, is a suspended section 6. The connection between the seedling lowering slide 2 and the sliding seat 12 is located above the suspended section 6. A counterweight 7 is installed on the suspended section 6. When the adjusting mechanism 5 drives the sliding seat 12 to move back and forth on the adjusting track 4, the suspended section 6 also slides back and forth, thus swinging the counterweight 7. Under the inertia of the swinging counterweight 7, the suspended section 6 of the seedling lowering slide 2 will undergo a large degree of deformation, narrowing the suspended section 6 to prevent the seedlings from passing through the narrowed suspended section 6. (See attached diagram) Figure 2 As shown, in practical applications, the curvature of the seedling lowering slide 2 on both sides is not consistent. In addition, the sliding speed of different seedlings in the seedling lowering slide 2 is prone to differences. Therefore, even if the seedling supply mechanism 3 supplies seedlings to the seedling lowering slide 2 on both sides at the same time, it is difficult to ensure that the seedlings on both sides can slide out from the lower end of the seedling lowering slide 2 at the same time. This will result in irregular spacing of seedlings after planting, and the seedlings will not be neatly arranged, which is not conducive to the subsequent management of seedlings.

[0027] In this invention, a technical solution is adopted in which the lower end of the seedling lowering slide 2 can move back and forth with the sliding seat 12. Firstly, during the continuous shaking of the seedling lowering slide 2, the seedlings can be prevented from getting stuck in the seedling lowering slide 2, ensuring that the seedlings gradually slide down to the suspended section 6 of the seedling lowering slide 2. Secondly, when the suspended section 6 shakes back and forth, it will narrow under the action of the counterweight 7, preventing the seedlings from continuing to slide down. After the suspended section 6 stops shaking, the suspended section 6 returns to its original state, thereby controlling the seedlings on both sides to fall down at the same time, so that the seedlings are arranged more neatly after planting.

[0028] As attached Figure 4 As shown, two counterweights 7 are arranged opposite each other on the suspended section 6, and the line connecting the two counterweights 7 is consistent with the extension direction of the adjusting track 4. Furthermore, the suspended section 6 of the seedling lowering slide 2 has different properties from other sections. The suspended section 6 of the seedling lowering slide 2 is softer, more elastic, and easier to bend inwards than outwards. Therefore, when the suspended section 6 moves back and forth with the sliding seat 12, the two counterweights 7 will move closer to each other under the action of inertia, thereby narrowing the suspended section 6 and hindering the passage of seedlings. In contrast, the other sections of the seedling lowering slide 2 are harder. When the sliding seat 12 moves back and forth, the deformation of the other sections of the seedling lowering slide 2 is smaller, and they will not hinder the sliding of seedlings due to narrowing deformation. On the contrary, because the seedling lowering slide 2 is constantly shaking, it can prevent seedlings from getting stuck in the seedling lowering slide 2.

[0029] The counterweight 7 is positioned on the outer wall of the suspended section 6 of the seedling lowering slide 2. If the counterweight 7 were positioned on the inner wall of the suspended section 6, it would easily affect the sliding of the seedlings within the seedling lowering slide 2. Positioning the counterweight 7 near the slide outlet of the seedling lowering slide 2 allows for greater deformation and narrowing of the suspended section 6 when it sways, resulting in a better obstruction effect on the seedlings.

[0030] As attached Figure 2 As shown, the seedling supply mechanism 3 includes two sets of chain rings 8, which supply seedlings to the seedling discharge channels 2 on both sides. Several seedling buckets 9 are arranged on the outer side of the chain rings 8. The chain rings 8 are driven to rotate by a motor and gears. When the chain rings 8 rotate, they alternately deliver each seedling bucket 9 to an opening at the top of the seedling discharge channel 2, allowing the seedlings in the buckets 9 to fall into the channel 2. The seedling buckets 9 are vertically connected, and the vehicle body 1 has a platform. When the seedling buckets 9 are not aligned with the top opening of the discharge channel 2, the platform supports the seedlings inside.

[0031] The two sets of ring chains 8 are arranged one after the other on the vehicle body 1. The seedling slides 2 on both sides are deformed to adapt to the two sets of ring chains 8, so that the bending shape of the seedling slides 2 on both sides is different. Therefore, the sliding speed of the seedlings in the seedling slides 2 on both sides will be different. It is difficult to ensure that the seedlings in the seedling slides 2 on both sides fall into the planting position at the same time, which can easily lead to the seedlings being arranged unevenly and is not conducive to the subsequent management of the seedlings.

[0032] As attached Figure 3 As shown, the adjustment mechanism 5 includes a central rotating rod 10, the center of which is the rotation center. A motor that drives the central rotating rod 10 to rotate is located inside the vehicle body 1. Both ends of the central rotating rod 10 are connected to sliding seats 12 on both sides via connecting rods 11. One end of the connecting rod 11 is hinged to the end of the central rotating rod 10, and the other end is hinged to the sliding seat 12. When the central rotating rod 10 rotates, the connecting rods 11 at both ends drive the sliding seats 12 on both sides to slide synchronously, thereby changing the planting row spacing of the seedlings.

[0033] As attached Figure 4 As shown, the sliding seat 12 is equipped with a furrow opener 13 and a soil covering device 14, which are located on the front and rear sides of the lower outlet of the seedling chute 2, respectively. During the movement of the vehicle body 1, the furrow opener 13 digs planting furrows in the soil, and the soil covering device 14 covers the planting furrows with soil. Seedlings sliding out of the seedling chute 2 fall into the planting furrows dug by the furrow opener 13, and the soil covering device 14 covers the seedlings in the planting furrows with soil.

[0034] As attached Figure 3As shown, a nozzle 15 is provided on the sliding seat 12, and a water tank and water pipe for supplying water to the nozzle 15 are provided on the vehicle body 1. The water tank is located inside the vehicle body 1, and a water pump is also provided on the water tank to pump the water in the water tank to the nozzle 15. The nozzle 15 is located behind the soil covering device 14 to spray water onto the seedlings after soil covering.

[0035] The present invention also provides a method for operating a seedling arrangement trench planting device, comprising the following steps:

[0036] Step S1: Manually load the seedlings into the seedling buckets 9 on the two sets of ring chains 8. There are baskets on both sides of the vehicle body 1 to store the seedlings. Preset the seedling exit position of the seedling slides 2 on the adjustable track 4, that is, determine the planting row spacing of the seedlings as needed.

[0037] Step S2: The vehicle body 1 moves forward. The vehicle body 1 can be manually pushed forward or the driving wheels can be actively rotated to drive the vehicle body 1 to move forward automatically. The two sets of ring chains 8 rotate under the drive of the motor, so that the seedling bucket 9 is positioned opposite the top of the seedling lowering slide 2, and then the seedling is sent to the seedling lowering slide 2. At the same time, the central rotating rod 10 rotates back and forth under the drive of the motor, so that the sliding seats 12 on both sides move back and forth around their respective seedling positions on the adjusting track 4, thereby causing the seedling lowering slide 2 to shake and swing the counterweight 7, so that the suspended section 6 of the seedling lowering slide 2 is narrowed.

[0038] Step S3: After the seedling bucket 9 moves with the ring chain 8 to the top opening of the seedling chute 2, the seedlings in the seedling bucket 9 fall into the seedling chute 2 and slide down along the swaying seedling chute 2. Because the seedling chute 2 is swaying, the seedlings are not easy to get stuck in the seedling chute 2. The seedlings stop sliding down after reaching the narrowed suspended section 6.

[0039] Step S4: The central rotating rod 10 stops rotating, so that the sliding seat 12 stops at the seedling position of the adjusting track 4; after the central rotating rod 10 stops rotating, the counterweight 7 stops swinging, and the suspended section 6 recovers from the narrowed state, so that the seedlings can pass through the recovered suspended section 6. Then, the seedlings in the seedling slides 2 on both sides fall simultaneously onto the planting trenches dug by the trench openers 13 on both sides, so that the seedlings are arranged neatly. Then, the soil covering device 14 covers the seedlings in the planting trenches with soil, and the nozzle 15 sprays water onto the seedlings after covering the soil. Then, return to step S2 to start the next round of seedling planting.

[0040] By using the above working method, even when the curves of the seedling channels on both sides are different, the seedlings on both sides can fall synchronously, making the planted seedlings more uniform and easier to manage; moreover, as the seedlings move along the seedling channel 2, the seedling channel 2 will sway, making it less likely for the seedlings to get stuck in the seedling channel 2.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
