Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a film perforation device and a film-covering seeder including the device. Background Technology

[0002] In modern agricultural production, mulching technology is widely used due to its advantages such as heat preservation, moisture retention, fertilizer retention, and suppression of weed growth. The seeder is a key piece of equipment for implementing this technology, and the traditional operation method usually involves mulching first and then sowing. Specifically, existing seeders are typically equipped with a mulching device that, during operation, first smoothly covers the prepared ridge surface with mulch.

[0003] However, this traditional process has a significant drawback: after mulching, the film completely seals the soil surface, and subsequent sowing is still required. At this point, planting holes must be manually or mechanically made in the film one by one, and then the seeds are placed into the holes using a seeder. This separation of "mulching" and "hole-making sowing" means the entire sowing process is divided into two independent stages, sometimes even requiring agricultural machinery to enter the field twice. This severely impacts the overall efficiency of farmland operations and cannot meet the needs of large-scale, intensive agricultural production. Furthermore, the additional manual hole-making or specialized hole-making equipment increases labor and equipment costs, and the two field-making operations also lead to increased fuel consumption. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a film perforation device and a film-covering and seeding machine that integrates film covering and perforation seeding, effectively improving work efficiency and reducing production costs.

[0005] This utility model is achieved through the following technical solution:

[0006] A thin film punching device includes a punching frame and further includes:

[0007] A guide cylinder, which is vertically mounted on the punching machine frame;

[0008] A punching cylinder, which is vertically disposed inside the guide cylinder and can move up and down along the guide cylinder;

[0009] A lifting drive device includes a motor mounted on the punching machine frame. The output end of the motor is driven by a connecting rod assembly, and the output end of the connecting rod assembly is driven to the upper end of the punching cylinder for driving the punching cylinder to lift.

[0010] As a further improvement of this utility model, the linkage assembly includes a first linkage and a second linkage. One end of the first linkage is fixed to the output end of the motor, and the other end of the first linkage is hinged to one end of the second linkage. The other end of the second linkage is hinged to the upper end of the punching cylinder.

[0011] As a further improvement of this utility model, the second connecting rod includes an intermediate connecting rod and end connecting rods disposed at both ends of the intermediate connecting rod. The intermediate connecting rod is a screw rod, and the end connecting rods are threadedly connected to the intermediate connecting rod. The end connecting rods at both ends are respectively hinged to the first connecting rod and the upper end of the punching cylinder by pins.

[0012] As a further improvement of this utility model, it also includes a mud removal device, which is used to scrape off the mud adhering to the outer wall and / or inner wall of the perforated cylinder.

[0013] As a further improvement of this utility model, the desliming device includes an external desliming cylinder, which is fixed on the drilling machine frame and located below the guide cylinder. The external desliming cylinder is sleeved on the outside of the drilling cylinder, and the inner wall of the external desliming cylinder is in contact with the outer wall of the drilling cylinder.

[0014] As a further improvement of this utility model, the desliming device includes an internal desliming column, which is disposed inside the perforating cylinder, and the outer wall of the internal desliming column is in contact with the inner wall of the perforating cylinder.

[0015] As a further improvement of this utility model, the upper end of the internal mud removal column is provided with a connecting pin, the upper end of the guide cylinder is provided with a pin hole, the connecting pin is inserted into the pin hole, and the cylinder wall of the perforated cylinder is provided with a vertical clearance groove, through which the connecting pin passes.

[0016] As a further improvement of this utility model, the lower end of the internal mud removal column protrudes from the lower end of the perforating cylinder when the perforating cylinder rises to its highest position.

[0017] As a further improvement of this utility model, the lower end of the punching cylinder has a tapered portion.

[0018] Based on the same concept, this embodiment also discloses a film-covered seeding machine, including the film perforation device described above.

[0019] The beneficial effects of this utility model are as follows: In this utility model, the motor drives the linkage assembly to move, and the linkage assembly converts the rotational output of the motor into linear reciprocating motion, which ultimately drives the punching cylinder to make precise vertical lifting and lowering motion under the constraint of the guide cylinder. This achieves synchronous punching of the mulch film during the forward movement, thereby realizing the synchronous operation of mulching and punching of the mulch film planter, avoiding secondary entry into the field, and significantly improving work efficiency.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0030] refer to Figures 1 to 6 The present utility model embodiment discloses that:

[0031] A mulching seeder includes a working frame 1, on which a traveling mechanism 2 is provided. A mulching mechanism 3, a film perforation device, and a sowing mechanism 4 are sequentially arranged along the water flow direction on the working frame 1. The traveling mechanism 2 drives the entire mulching seeder to travel stably along a preset path on the field ridges. The mulching mechanism 3 is used to lay the mulch film, and the sowing mechanism 4 is used to sow seeds into the perforated holes. This is existing mature technology and will not be described in detail here. The core of this embodiment lies in the film perforation device.

[0032] The film perforation device includes a perforation frame 5, which is mounted on a working frame 1, and a guide cylinder 6, which is vertically mounted on the perforation frame 5; a perforation cylinder 7, which is vertically mounted inside the guide cylinder 6 and can move up and down along the guide cylinder 6; and a lifting drive device, which includes a motor 8 mounted on the perforation frame 5. The output end of the motor 8 is driven by a connecting rod assembly, and the output end of the connecting rod assembly is driven to the upper end of the perforation cylinder 7 to drive the perforation cylinder 7 to move up and down. During operation, the motor 8 drives the connecting rod assembly to move, and the connecting rod assembly converts the rotational output of the motor 8 into linear reciprocating motion, ultimately driving the perforation cylinder 7 to make precise vertical lifting and lowering movements under the constraint of the guide cylinder 6. This achieves synchronous punching of the mulch film during forward movement, thereby realizing the synchronous operation of mulching and perforation of the mulch film planter, avoiding secondary entry into the field, and significantly improving work efficiency.

[0033] Specifically, the linkage assembly includes a first linkage 9 and a second linkage 10. One end of the first linkage 9 is fixed to the output end of the motor 8, and the other end of the first linkage 9 is hinged to one end of the second linkage 10. The other end of the second linkage 10 is hinged to the upper end of the punching cylinder 7. With the above arrangement, the motor 8 drives the first linkage 9 to perform circular motion, the first linkage 9 drives the second linkage 10 through the hinge point, and the other end of the second linkage 10 drives the punching cylinder 7 to rise and fall through the hinge point. These together form a crank-slider mechanism. This transmission method has a simple and compact structure, high transmission efficiency, and can stably transmit the power of the motor 8 to the punching cylinder 7, ensuring the accuracy and continuity of the rising and falling action of the punching cylinder 7.

[0034] When drilling holes, the fixed-length connecting rod cannot adapt to the plant spacing requirements of different crops. The second connecting rod 10 includes an intermediate connecting rod 101 and end connecting rods 102 at both ends of the intermediate connecting rod 101. The intermediate connecting rod 101 is a screw rod, and the end connecting rods 102 are threaded to the intermediate connecting rod 101. The end connecting rods 102 at both ends are hinged to the upper ends of the first connecting rod 9 and the drilling cylinder 7 respectively by pins. By rotating the intermediate connecting rod 101, the distance between the two end connecting rods 102 can be adjusted, thereby changing the overall length of the second connecting rod 10. When the length of the second connecting rod 10 changes, the lifting stroke of the drilling cylinder 7 changes accordingly, thereby affecting the drilling depth or the hole spacing in the direction of travel, so as to adapt to the plant spacing requirements of different crops during sowing, thereby improving the versatility of the device and adapting to different agronomic requirements.

[0035] During operation, the inner and outer walls of the punching cylinder 7 are prone to soil adhesion. Therefore, in order to avoid soil accumulation affecting the punching accuracy and subsequent sowing, this device is also equipped with a soil removal device, which is used to scrape off the soil adhering to the outer and / or inner walls of the punching cylinder 7.

[0036] Specifically, the desliming device includes an external desliming cylinder 11, which is fixed on the drilling machine frame 5 and located below the guide cylinder 6. The external desliming cylinder 11 is sleeved on the outside of the drilling cylinder 7, and the inner wall of the external desliming cylinder 11 is in contact with the outer wall of the drilling cylinder 7. When the drilling cylinder 7 rises, the external desliming cylinder scrapes away the mud from the outer wall of the drilling cylinder 7, thereby ensuring the stability and reliability of the drilling operation and extending the service life of the equipment.

[0037] In addition, the desliming device also includes an internal desliming column 12, which is disposed inside the perforating cylinder 7, and the outer wall of the internal desliming column 12 is in contact with the inner wall of the perforating cylinder 7. The upper end of the internal desliming column 12 is provided with a connecting pin 13, and the upper end of the guide cylinder 6 is provided with a pin hole. The connecting pin 13 is inserted into the pin hole. The cylinder wall of the perforating cylinder 7 is provided with a vertical clearance groove 14, through which the connecting pin 13 passes. When the perforating cylinder 7 moves up and down under the action of the lifting drive device, the connecting pin 13 slides in the clearance groove 14. This allows the internal descaling column 12 to remain stationary relative to the guide cylinder 6, while the perforating cylinder 7 moves up and down relative to the guide cylinder 6. At this time, the outer wall of the internal descaling column 12 is in close contact with the inner wall of the perforating cylinder 7, effectively scraping away the soil adhering to the inner wall of the perforating cylinder 7. Simultaneously, when the perforating cylinder 7 rises to its highest position, the lower end of the internal descaling column 12 protrudes beyond the lower end of the perforating cylinder 7. Thus, during the process of the perforating cylinder 7 completing its drilling and rising, the internal descaling column 12 can completely push out the soil from the inner wall of the perforating cylinder 7, preventing soil from accumulating and clogging inside the perforating cylinder 7, and further improving the descaling effect.

[0038] To improve drilling efficiency and quality, the lower end of the drilling cylinder 7 has a tapered portion 15. The tapered design allows the drilling cylinder 7 to cut into the mulch and soil more quickly, reducing drilling resistance and ensuring that the edges of the drilled holes are neat, which facilitates precise seeding by the subsequent sowing mechanism 4.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
