Description

Technical Field

[0001] The invention belongs to the field of vegetable planting devices, and in particular, relates to a vegetable planting device with adjustable spacing. Background Art

[0002] Most existing seed drills use a fixed seeding spacing design, which, while it can meet basic needs in some cases, faces many limitations in actual agricultural production. Since different types of plants have different requirements for seeding spacing, a fixed seeding spacing seed drill cannot flexibly respond to these needs. For example, some vegetables require tighter seeding spacing, while some root crops require a larger seeding distance. Since the seeding spacing cannot be adjusted, farmers can only choose a seed drill suitable for a certain type of crop, while other crops may require equipment replacement or tedious manual adjustments.

[0003] This limitation not only reduces the versatility and applicability of the seed drill, but also leads to a lot of time waste and increased costs. Farmers have to frequently change seeding equipment when facing different crops, or adjust the seeding spacing through manual intervention, which not only increases the cost of equipment use, but also significantly increases labor intensity. Moreover, manual intervention often makes it difficult to achieve precise seeding spacing, resulting in unstable seeding quality, which in turn affects crop growth and yield.

[0004] In addition, the efficiency of the seeder is greatly reduced due to the inability to flexibly adjust the sowing spacing. Farmers often need to make multiple adjustments or change machines according to the type of crops, especially in large-scale planting. Frequent equipment switching is not only time-consuming and labor-intensive, but may also affect the production rhythm and reduce overall agricultural production efficiency.

DETAILED DESCRIPTION

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] See also Figure 1-8 As shown, in this embodiment, a vegetable planting device with adjustable spacing is provided, including a seed feeding adjustment mechanism and a sowing component, the feeding adjustment structure includes a feeding box 7 and two connecting frames 1 and a fixed frame 2, a mounting plate 3 is fixedly connected to the bottom of the feeding box 7, a plurality of connecting columns 4 are arranged between the mounting plate 3 and the upper part of the edge of the connecting frame 1, and a combination mechanism for fixed connection between agricultural machinery is fixedly connected to one side of the fixed frame 2; it should be noted that: the lower end of the connecting column 4 is fixedly connected to the top of the connecting frame 1, and the upper end of the connecting column 4 is slidably connected to the top of the mounting plate 3 through the guide rail technology in the prior art.

[0040] The sowing assembly includes a plurality of mounting frames hinged between the connecting frame 1 and the fixed frame 2, and the mounting frame includes two side panels 5. A connecting plate 6 is fixedly connected between the two side panels 5 to divide the mounting frame into a front end space and a rear end space. A sowing mechanism is provided at the rear end space, and the discharge port of the feeding box 7 cooperates with the sowing mechanism. It should be noted that the connecting plate 6 is a connecting piece between the two side panels 5, which plays a role in fixing the two side panels 5, and the connecting tube 12 is rotatably connected to the inside of the rear end space. The interval between the side panels 5 is the same as the space between the connecting frame 1 and the fixed frame 2. The position of the side panel 5 corresponds to the position of the side panel of the connecting frame 1 and the fixed frame 2, and the hinge is used to achieve the effect of the hinge. The present invention not only ensures the stable transportation of seeds through the seed feeding adjustment mechanism and the sowing assembly, but also can be adjusted according to the needs of different plants, so that the sowing spacing can be flexibly adjusted to meet the sowing requirements of various crops. This adjustable design improves the adaptability of the seeder and reduces the limitation that the traditional seeder can only operate under a fixed sowing spacing, thereby improving work efficiency and reducing manual labor intensity.

[0041] In this embodiment, the sowing mechanism includes a fixed plate 8 with a hollow structure located above the inner wall of the rear end space, a feed cylinder 9 corresponding to the axis of the hollow structure is connected to the top of the fixed plate 8, a cover plate 10 is fixedly connected to the top of the feed cylinder 9, a discharge port is provided on the side of the discharge box facing the feed port, a feed port is provided above the cover plate 10, a deformable bellows 11 is provided between the feed port and the discharge port, and a discharge piece 14 for discharging seeds is provided at the discharge port below the discharge cylinder; the deformable characteristics of the bellows 11 can adapt to the deformation requirements in different working environments, ensure the smooth flow of seeds, and reduce the problem of seed jamming or blockage.

[0042] The discharge member 14 includes a connecting tube 12 located below the rear end space, a first opening is provided above the connecting tube 12, a feeding member 13 connected to the discharge tube is fixedly connected above the first opening, a second opening is provided below the connecting tube 12, a discharge member 14 connected to the discharge tube is fixedly connected above the second opening, and a rotating disk 15 in the shape of a water wheel is rotatably connected inside the connecting tube 12. The seeds in the connecting tube 12 are discharged from the discharge member 14 through the setting of the rotating disk 15, thereby completing the sowing process of the vegetable seeds.

[0043] In this embodiment, a mounting frame 16 is fixedly connected to one side of the connecting plate 6, and a triangular bulldozer 17 is fixedly connected to the inside of the mounting frame 16 by bolts. It should be noted that the triangular tip of the bulldozer 17 faces the front wheel 45.

[0044] In this embodiment,

[0045] It also includes a first rotating rod 18 and a second rotating rod 19, both of which are rotatably connected to the front wheel 45 inside the front end space, and first through holes corresponding to the axis are opened on the opposite sides of the inner wall of the front end of the side plate 5, and the first rotating rod 18 is rotatably connected to the plurality of first through holes through bearings, and a first straight groove 21 is opened on the peripheral side of the first rotating rod 18, and a first mounting hole adapted to the first rotating rod 18 is opened on the opposite side of the front wheel 45, and a first slider sliding inside the first straight groove 21 is fixedly connected to one side of the inner wall of the first mounting hole;

[0046] A second through hole corresponding to the axis is provided inside the rear end of the side plate 5, and a positioning hole corresponding to the axis of the second through hole is provided on the opposite side of the connecting tube 12. The second rotating rod 19 is rotatably connected in the plurality of second through holes through bearings, and a second straight groove 23 is provided on the circumferential side of the second rotating rod 19. A second mounting hole matched with the second rotating rod 19 is provided on the opposite side of the rotating disk 15, and a second slider 24 sliding in the second straight groove 23 is fixedly connected to one side of the inner wall of the second mounting hole; the second straight groove 23 and the second slider 24 can slide when the spacing is adjusted later, and the second rotating rod 19 can be rotated by the rotation of the front wheel 45 when the spacing is not adjusted, and the cooperation of the first straight groove 21 and the first slider is similar.

[0047] One end of the first rotating rod 18 and one end of the second rotating rod 19 are both fixedly connected with the first synchronous wheel 25, and a synchronous belt is sleeved between the two first synchronous wheels 25. It should be noted that positioning cylinders are provided on both sides of the front wheel 45, and the ends of the positioning cylinders and the inner wall of the mounting frame abut against each other. Through the precise matching between the first synchronous wheel 25 and the second synchronous wheel 32, the power of the rotation of the front wheel 45 can be effectively transmitted to the rotating disk 15. Specifically, when the front wheel 45 starts to rotate, the first synchronous wheel 25 will rotate synchronously with the rotation of the front wheel 45, and the rotation of the first synchronous wheel 25 drives the second synchronous wheel 32 connected thereto to start rotating. The second synchronous wheel 32 is connected to the rotating disk 15 by gear meshing or driving, so that the rotating disk 15 also starts to rotate.

[0048] The rotation of the rotating disk 15 plays a key role in seed transportation and drop. The rotating disk 15 is usually designed with a special structure, such as a spiral or grooved surface, which can gradually guide the seeds to the discharge port when the disk rotates. As the rotating disk 15 rotates, the seeds flow downward along a predetermined path and finally fall accurately into the soil through the discharge port of the sowing mechanism.

[0049] In this embodiment, two first positioning plates 27 and second positioning plates 22 are fixedly connected to the top of the side plate 5, and the two second positioning plates 22 are located between the two first positioning plates 27. The two second positioning plates 22 are respectively fixedly connected with a guide rod 28 and rotatably connected with a screw rod 29 on the side facing the first positioning plate. A guide hole matched with the guide rod 28 and a threaded hole matched with the screw rod 29 are opened on one side of the first positioning plate 27.

[0050] In this embodiment, the connecting frame 1 and the fixed frame 2 are both U-shaped frame structures, and the fixed frame 2 and the connecting frame 1 are respectively rotatably connected with the first rear wheel 30 and the second rear wheel 31, and the second synchronous wheel 32 is fixedly connected to both sides of the first rear wheel 30, and the ends of the two screws 29 passing through the second positioning plate 22 are fixedly connected to the third synchronous wheel 33, and the second synchronous belt 34 is sleeved between the second synchronous wheel 32 and the third synchronous wheel 33. Through the cooperation between the screw 29 and its second synchronous wheel 32 and the third synchronous wheel 33, when the second rear wheel 31 contacts the ground and starts to rotate, the rotation of the second rear wheel 31 will directly drive the second synchronous wheel 32 connected thereto to rotate. Since the second synchronous wheel 32 and the third synchronous wheel 33 are connected by a synchronous belt, the rotation of the second synchronous wheel 32 will drive the third synchronous wheel 33 to rotate, thereby transmitting the rotation action to the screw 29 through mechanical transmission. Through the cooperation between the rear wheel and the synchronous transmission device, manual intervention is not required when adjusting the spacing, and the automatic adjustment of the sowing spacing can be achieved only through the driving of the agricultural machine and the rotation of the rear wheel.

[0051] In this embodiment, a rod body is fixedly connected to one side of the second synchronous wheel 32, and a rotating hole matching the rod body is provided on the opposite side of the fixed frame 2. A disc body 35 is fixedly connected to one end of the rod body passing through the rotating hole, and a plurality of slots 36 are provided on the peripheral side of the outer wall of the disc body 35 in a circular arrangement. The disc body 35 acts as a locking member. When the rear wheels of the seed drill are adjusted to the required spacing by the screw rod 29, the rotation and positioning of the disc body 35 will further help lock the position of the rear wheels. The close fit between the hook rod 40 and the slot 36 can effectively prevent the rear wheels from accidentally loosening or shifting due to vibration or external force during operation, thereby maintaining the accuracy and stability of the seeding spacing. The design of the hook rod 40 enables it to freely slide into or out of the slot 36 without the need for external force intervention, thereby achieving the locking and unlocking operations.

[0052] The advantage of this design is that it not only improves the reliability of rear wheel position locking, but also makes spacing adjustment and locking simple and fast. During the sowing process, the agricultural machine operator does not need to worry about the rear wheel position change due to vibration or long-term use.

[0053] In this embodiment, the combined mechanism includes two positioning rods 37 fixedly connected to both sides of the outer wall of the fixed frame 2, a guide plate 38 is slidably connected between the two positioning rods 37, a combined plate 39 is fixedly connected to one side of the guide plate 38, a hook rod 40 is fixedly connected below the combined plate 39, and the hook end of the hook rod 40 corresponds to the card slot 36 and is located below the disc body 35. The position of the rear wheel can be firmly locked during operation through the cooperation between the hook rod 40 and the card slot 36, and no matter what degree of vibration is encountered during travel, the rear wheel can be ensured to be fixed unchanged, thereby ensuring the stability of the seeding device, and the stability after the interval adjustment is ensured because the rear wheel will not rotate unnecessarily due to vibration.

[0054] In this embodiment, a plurality of linear drive mechanisms are fixedly connected to the bottom of the mounting plate 3, and a combination rod 41 is fixedly connected to the output end of the linear drive mechanism, and an extension rod 42 fixedly connected between the combination rods 41 is fixedly connected to one side of the combination plate 39, and a pressing frame 43 is fixedly connected to the lower end of the combination rod 41, and a seesaw 44 is fixedly connected between every two adjacent side plates 5. It should be noted that the shape of the lower part of the pressing frame 43 is the same as that of the seesaw 44, which is used to achieve abutment, and the top of the pressing frame 43 leaves a moving space when the seesaw 44 contacts the ground, thereby avoiding the situation in which the seesaw 44 contacts the side wall of the pressing frame 43 during the downward pressing process and causes motion interference. When the front wheel 45 contacts the ground, the bottom of the seesaw 44 reaches the bottom of the inner wall of the pressing frame 43, and when the spacing needs to be adjusted, the top of the seesaw 44 contacts the top of the inner wall of the pressing frame 43. The linear drive mechanism is one of a hydraulic cylinder, a linear cylinder, and an electric push rod.

[0055] Working principle: At the beginning of the sowing operation, the planting device is first firmly connected to the agricultural machine through the combined mechanism. Then, the required seeds are poured into the feeding box 7. The seeds in the feeding box 7 are transmitted to the feeding cylinder 9 through the bellows 11. A discharge port is provided below the feeding cylinder 9, and the seeds enter the connecting cylinder 12 from the discharge port and are transported downward along the connecting cylinder 12. Next, the agricultural machine is started, and the agricultural machine begins to pull the planting device forward.

[0056] During the movement, the front wheel 45 contacts the ground and starts to rotate, while the rear wheel leaves the ground. The rotation of the front wheel 45 is transmitted to other components through the first rotating rod 18. The first rotating rod 18 drives the first synchronous belt 26 to cooperate with the first synchronous wheel 25, thereby driving the second synchronous belt 34 to start rotating. The second synchronous belt 34 is connected to the rotating disk 15, driving the rotating disk 15 to rotate in the form of a water wheel.

[0057] When the rotating disc 15 rotates, it accurately sows the seeds into the grooves under the bulldozer 17 through the discharge piece 14. The bulldozer 17 loosens the soil during the movement to form grooves suitable for sowing, and the seeds are sown exactly in these grooves;

[0058] During the sowing process, if the sowing spacing needs to be adjusted, the linear drive mechanism is first started to move the pressure frame 43 fixedly connected to its output end downward. While the pressure frame 43 is pressed down, its contact with the bottom of the seesaw 44 is cancelled. As the pressure frame 43 moves downward, the combination plate 39 connected to the extension rod 42 also moves downward together, and the guide plate 38 moves downward synchronously between the two positioning plates. At this time, the downward movement of the combination plate 39 causes the hook end of the hook rod 40 to slide out of the card slot 36 of the disk body 35, unlocking the position of the card rod. The pressure frame 43 continues to press down, compressing the seesaw 44, and the seesaw 44 generates pressure, pushing the mounting frame to complete the movement away from the ground through the hinge.

[0059] Next, the rear wheel contacts the ground and starts to rotate. The cooperation between the second synchronous wheel 32 and the third synchronous wheel 33 drives the second synchronous belt 34 to rotate, thereby driving the screw 29 to work. The rotation of the screw 29 will adjust the distance between the two mounting frames. After the distance adjustment is completed, the device can continue the sowing operation, and the same applies to sowing after the subsequent adjustment is completed.

[0060] The present invention is not limited to the above-mentioned embodiments. Anyone should be aware that any structural changes made under the enlightenment of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention. The technology, shape, and structural parts not described in detail in the present invention are all well-known technologies.
