Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a soil perforation device for a wheat film-side seeder. Background Technology

[0002] In the field of agricultural machinery technology, the soil perforation device of wheat film-side seeders is a core component to ensure sowing quality. Through precisely designed perforation parts, it drills holes of appropriate depth and spacing on the soil surface in an orderly manner, providing an ideal implantation space for wheat seeds. In addition, the device can effectively break up the soil compaction layer, improve soil aeration and water permeability, and create a good soil environment for wheat growth. Therefore, the soil perforation device of wheat film-side seeders is particularly needed.

[0003] However, the existing soil aeration devices of wheat film-side seeders face challenges from complex agronomic environments. Soil texture and moisture conditions vary greatly between different plots, and planting agronomic requirements differ from place to place. Existing soil aeration devices have shortcomings when adjusting the aeration frequency. Most existing devices cannot flexibly adjust the aeration frequency in real time according to changes in soil compaction and sowing density. When faced with diverse needs such as denser aeration for clay soil or sparser aeration for sandy soil, it is difficult to achieve precise frequency control. This limitation not only reduces the efficiency of aeration operations but also affects the consistency of sowing depth and spacing, resulting in uneven seed distribution and creating hidden dangers for subsequent crop growth. Utility Model Content

[0004] The purpose of this invention is to provide a soil perforation device for a wheat film-side seeder, in order to solve the challenges posed by existing soil perforation devices for wheat film-side seeders mentioned in the background art. These devices face challenges from complex agronomic environments, with varying soil textures and moisture conditions across different plots, coupled with diverse agronomic requirements in different regions. Existing soil perforation devices exhibit shortcomings when adjusting the perforation frequency. Most existing devices cannot flexibly rotate according to real-time changes in soil compaction and sowing density. When faced with diverse needs such as denser perforation in clay soils or sparser perforation in sandy soils, precise frequency control is difficult to achieve. This limitation not only reduces the efficiency of perforation operations but also affects the consistency of sowing depth and spacing, leading to uneven seed distribution and creating potential problems for subsequent crop growth.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil punching device for a wheat film-side seeder, comprising a frame, a seed box fixedly connected to the upper surface of the frame, a drive wheel rotatably connected to one side surface of the frame, a support fixedly connected to one side surface of the frame, a pressing wheel rotatably connected to one side surface of the support, and a punching mechanism provided on one side surface of the frame.

[0006] The punching mechanism includes a bottom plate, which is fixedly connected to one side surface of the frame. One side surface of the bottom plate is fixedly connected with a motor.

A rectangular hole is formed on one side surface of the armature block. The lower surface of the bottom plate is fixedly connected with a fixing plate. A sliding hole is formed on one side surface of the fixing plate. A rotating wheel is rotatably connected to the inner wall surface of the sliding hole. A movable member is slidably connected to the inner wall surface of the sliding hole. A groove is formed on one side surface of the movable member. A rectangular block is fixedly connected to the upper surface of the movable member. A pointed head is fixedly connected to one side surface of the movable member.

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a soil punching device for a wheat film-side seeder, including a frame 1, a seed box 2 fixedly connected to the upper surface of the frame 1, a drive wheel 3 rotatably connected to one side surface of the frame 1, a support 4 fixedly connected to one side surface of the frame 1, a pressing wheel 5 rotatably connected to one side surface of the support 4, and a punching mechanism 6 provided on one side surface of the frame 1.

[0022] The drilling mechanism 6 includes a base plate 601, which is fixedly connected to one side surface of the frame 1. A motor 602 is fixedly connected to one side surface of the base plate 601. A housing 603 is fixedly connected to the upper surface of the base plate 601. A bit block 604 is fixedly connected to one side surface of the housing 603. A rectangular hole 605 is formed on one side surface of the bit block 604. A fixing plate 606 is fixedly connected to the lower surface of the base plate 601. A sliding hole 607 is formed on one side surface of the fixing plate 606. A rotating wheel 608 is rotatably connected to the inner wall surface of the sliding hole 607. A movable part 609 is slidably connected to the inner wall surface of the sliding hole 607. A groove 610 is formed on one side surface of the movable part 609. A fixed connection is formed on the upper surface of the movable part 609. A rectangular block 611 is attached, a pointed tip 612 is fixedly connected to one side surface of the movable part 609, and an eccentric wheel 613 is fixedly connected to one side surface of the motor 602. Through the arrangement of the base plate 601, motor 602, outer shell 603, armature block 604, rectangular hole 605, fixing plate 606, sliding hole 607, rotating wheel 608, movable part 609, groove 610, rectangular block 611, pointed tip 612 and eccentric wheel 613, when in use, the motor 602 is powered on and started, driving the eccentric wheel 613 to rotate at high speed. Since the eccentric wheel 613 is slidably connected to the inner wall of the movable part 609 and its diameter matches the height of the inner wall of the movable part 609, the eccentric wheel 613 will continuously push the movable part 609 to move when rotating. One end of the movable part 609 slides within the sliding hole 607, while the pointed end 612 at the other end reciprocates in a linear motion. Simultaneously, the rotating wheel 608 is installed within the sliding hole 607, with its outer wall fitting against the inner wall of the groove 610 of the movable part 609. The rotating wheel 608 reduces friction during the sliding of the movable part 609, making the sliding of the movable part 609 smoother. The rectangular block 611 above the movable part 609 engages with the rectangular hole 605 on the latch block 604, guiding and limiting the movement of the movable part 609, ensuring that the pointed end 612 moves vertically up and down. The rotation speed of the eccentric wheel 613 can be adjusted according to different terrains, improving applicability and ensuring construction quality.

[0023] Furthermore, two drive wheels 3 of the same size are symmetrically arranged along the frame 1, and two compaction wheels 5 of the same size are symmetrically arranged along the support 4. With the arrangement of drive wheels 3 and compaction wheels 5, the drive wheels 3 drive the device to move during use. The symmetrical layout ensures that the whole machine is evenly stressed during movement. The compaction wheels 5 compact the relatively loose soil after drilling. The symmetrical structure allows the compaction wheels 5 to apply uniform pressure to the soil on both sides, avoiding local over- or under-compaction, ensuring close contact between the seeds and the soil, which is beneficial for the seeds to absorb water and nutrients from the soil.

[0024] Further, the bottom plate 601, the armature block 604, the motor 602, and the fixing plate 606 are parallelly distributed. The eccentric wheel 613 is slidably connected to the inner wall surface of the movable member 609. Through the settings of the bottom plate 601, the armature block 604, the motor 602, and the fixing plate 606, during use, the bottom plate 601 serves as a basic support component, firmly fixing the armature block 604, the motor 602, and the fixing plate 606 on the frame 1. This regular parallel layout also contributes to the smooth operation of the mechanism.

[0025] Further, the outer wall dimensions of the rectangular block 611 match the inner wall dimensions of the rectangular hole 605, and the diameter of the eccentric wheel 613 matches the inner wall height of the movable member 609. Through the settings of the rectangular block 611 and the rectangular hole 605, during use, when the motor 602 drives the eccentric wheel 613 to rotate, the eccentric wheel 613 pushes the movable member 609 to perform a reciprocating linear motion. At this time, the rectangular block 611 above the movable member 609 slides synchronously within the rectangular hole 605, effectively preventing the movable member 609 from experiencing lateral displacement or晃动 during movement.

[0026] Further, the inner wall dimensions of the sliding hole 607 match the outer wall dimensions of one end of the movable member 609 away from the armature block 604, and the outer wall dimensions of the rotating wheel 608 match the inner wall dimensions of the groove 610. Through the settings of the rotating wheel 608 and the groove 610, during use, the outer wall of the rotating wheel 608 is closely fitted to the inner wall of the groove 610 of the movable member 609. During the movement of the movable member 609, the rotating wheel 608 rolls accordingly, converting the original sliding friction into rolling friction, greatly reducing the frictional resistance between the movable member 609 and the fixing plate 606, and making the operation of the punching mechanism 6 more efficient, stable, and durable.

[0027] Further, the appearance of the movable member 609 is designed in a "middle" shape, and the rotating wheel 608, the eccentric wheel 613, and the motor 602 are parallelly distributed. Through the setting of the movable member 609, during use, the "middle" - shaped structure of the movable member 609 endows the movable member 609 with good mechanical properties. The two protruding parts on both sides not only provide a stable rolling track for the rotating wheel 608, ensuring smooth rolling of the rotating wheel 608 within the groove 610 and reducing the movement resistance, but also enhance the structural strength of the movable member 609 itself, making it not easily deformed under the continuous push of the eccentric wheel 613 and ensuring the stability of the punching action.

[0028] Further, the sliding hole 607 coincides with the vertical center line of the rectangular hole 605. There are two seed boxes 2 with the same size, and they are symmetrically distributed along one side surface of the frame 1. Through the settings of the sliding hole 607 and the rectangular hole 605, during use, the sliding hole 607 and the rectangular hole 605 restrict the movable member 609. Since the center lines of the sliding hole 607 and the rectangular hole 605 coincide, it ensures the accuracy of the punching position and provides an accurate target point for the seeding of the seed box 2.

[0029] Working principle: When the seeder is started, the drive wheel 3 rotates, driving the entire seeder to move in the field. At the same time, the drilling mechanism 6 starts to work, the motor 602 is powered on and starts, driving the eccentric wheel 613 to rotate at high speed. Since the eccentric wheel 613 is slidably connected to the inner wall of the moving part 609, and its diameter matches the height of the inner wall of the moving part 609, the eccentric wheel 613 will continuously push the moving part 609 to move when it rotates. One end of the movable part 609 slides within the sliding hole 607, while the pointed end 612 at the other end reciprocates in a linear motion. Simultaneously, the rotating wheel 608 is installed within the sliding hole 607, with its outer wall fitting against the inner wall of the groove 610 of the movable part 609. The rotating wheel 608 reduces friction during the sliding of the movable part 609, making the sliding of the movable part 609 smoother. The rectangular block 611 above the movable part 609 engages with the rectangular hole 605 on the bit block 604, guiding and limiting the movement of the movable part 609, ensuring that the pointed end 612 moves vertically up and down. When the pointed end 612 moves downward, it penetrates the soil to complete the drilling action; when it moves upward, it detaches from the soil, preparing for the next drilling. During the movement of the seeder, the drilling mechanism 6 continues to work, and the pointed end 612 continuously drills holes in the soil. Meanwhile, the seeds in the seed box 2 fall into the pre-drilled holes through a specific channel under the action of gravity or other seed delivery devices. Then, the press roller 5 compacts the soil after drilling, completing the sowing process. The motor 602 is model YE2-132S-4. This completes the use of the soil drilling device of the wheat film-side seeder.
