Description

Technical Field

[0001] This utility model relates to the field of agricultural planting machinery and equipment technology, and in particular to a corn planting machine with film covering. Background Technology

[0002] With the continuous development of agricultural modernization, plastic film mulching technology has been widely used in corn planting. This technology can effectively retain soil moisture, increase soil temperature, and inhibit weed growth, thereby improving corn yield and quality.

[0003] For example, CN214676498U discloses a corn planting machine on film, including a hydraulic cylinder. The bottom of the first hydraulic cylinder is fixedly connected to an installation plate, and the piston end of the first hydraulic cylinder is fixedly connected to a second push rod. The bottom of the second push rod is fixedly connected to a funnel, and the bottom of the funnel is fixedly connected to a plurality of connecting columns. The bottom of the connecting columns is fixedly connected to a drill bit. The top circumferential outer wall of the funnel is fitted with a telescopic frame, and a through hole is opened in the middle of the top of the telescopic frame.

[0004] This patent has limitations in the seed dispensing stage. The seeds fall into the soil each time through a hopper, and the relatively simple structure of the seed metering device makes it difficult to guarantee the accuracy of each dispensing, leading to seed spillage and waste. This makes it difficult to precisely control the sowing amount, affecting the standardization and efficiency of corn planting. Furthermore, existing planting machinery also has certain defects in the film-breaking and sowing stage. Some devices cannot guarantee the stability and accuracy of the action when piercing the film and inserting it into the soil, resulting in excessive film damage or inconsistent sowing depth, affecting the germination rate and subsequent growth of corn seeds. Therefore, a film-covered corn planting machine needs to be designed to solve these problems. Utility Model Content

[0005] The main purpose of this invention is to provide a corn planting machine on a film, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A corn planting machine with film includes a frame, with wheels on all four sides of the outer side of the frame. Two push handles are fixedly connected to the upper rear part of the frame. A feeding device is inserted and installed in the middle of the upper part of the frame. A sowing device is fixedly connected to the upper left part of the frame. Sliding grooves are opened on the lower part of the left and right walls of the frame. Pressing rollers are movably installed on the front part of the left and right walls of the frame through bearings.

[0008] The feeding device includes a corn seed box and a first drive motor. The output end of the first drive motor passes through the corn seed box and is fixedly connected to a feeding roller. The outer surface of the feeding roller has several dropping grooves. The middle of the front wall and the middle of the rear wall of the corn seed box are fixedly connected to guide plates. The lower part of the front wall and the lower part of the rear wall of the corn seed box are fixedly connected to transparent semi-circular plates. The middle of the lower end of the corn seed box is fixedly connected to a feeding pipe. An encoder is provided at the other end of the first drive motor. The corn seed box is inserted and installed in the middle of the upper end of the frame.

[0009] Preferably, the sowing device includes a second drive motor, the output end of which passes through the frame and is fixedly connected to an eccentric wheel. A crank rod is sleeved on one side of the eccentric wheel, and a connecting shaft is inserted and installed on the side of the crank rod away from the eccentric wheel. A planting plate is fixedly connected to the right end of the connecting shaft. A telescopic tube is fixedly connected to the middle of the upper end of the planting plate. Slider blocks are fixedly connected to the middle of the left and right ends of the planting plate. A pointed groove is opened at the lower end of the planting plate. The second drive motor is fixedly installed on the upper left end of the frame.

[0010] Preferably, the inner sides of the two transparent semi-circular plates are respectively attached to the front and rear of the outer surface of the feeding roller, and the left end of the feeding roller is movably mounted to the corn seed box via a bearing.

[0011] Preferably, the two guide plates are inclined at a relative 20-degree angle, and the bottom of each guide plate is in close contact with the upper part of the outer surface of the feed roller.

[0012] Preferably, the relative spacing between the two guide plates is the same as the diameter of the drop groove.

[0013] Preferably, the feeding pipe is the same as the inside of the corn seed box and is fixedly installed with the telescopic pipe.

[0014] Preferably, the two sliders are slidably connected within the groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, the first drive motor drives the feeding roller to rotate inside the corn seed box. The guide plate, which is inclined at 20 degrees and whose bottom is close to the upper part of the feeding roller, guides the seeds to fall accurately into the dropping groove that matches the distance between the guide plate and the seed. The transparent semi-circular plate prevents the seeds from leaking to the side, and the encoder records the number of rotations of the feeding roller to control the sowing amount. This achieves orderly and accurate dispensing of corn seeds, avoids seed spillage and waste, and ensures that the sowing amount is accurate and controllable.

[0017] 2. In this utility model, a second drive motor drives an eccentric wheel to rotate. The eccentric wheel converts circular motion into linear motion through a crank, driving the planting plate to move. The slider on the planting plate slides in the groove of the frame, ensuring smooth and precise movement. When the planting plate moves downward, the lower pointed groove pierces the mulch film and inserts into the soil. At the same time, the seeds in the telescopic tube fall into the soil to complete the sowing. Subsequently, the planting plate moves upward to reset, so that it accurately completes the actions of piercing the mulch film, sowing, and resetting, effectively improving the efficiency and quality of corn sowing on the film.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A corn planting machine with film covering includes a frame 1, characterized in that: wheels 2 are provided on all four sides of the outer side of the frame 1, two push handles 5 are fixedly connected to the upper rear part of the frame 1, a feeding device 6 is inserted and installed in the middle of the upper part of the frame 1, a sowing device 7 is fixedly connected to the upper left part of the frame 1, a sliding groove 3 is opened on the lower part of the left plate wall and the lower part of the right plate wall of the frame 1, and a film pressing roller 4 is movably installed on the front part of the left plate wall and the front part of the right plate wall of the frame 1 through bearings.

[0029] In this embodiment, the feeding device 6 includes a corn seed box 61 and a first drive motor 62. The output end of the first drive motor 62 passes through the corn seed box 61 and is fixedly connected to a feeding roller 64. The outer surface of the feeding roller 64 has several dropping grooves 65. Guide plates 68 are fixedly connected to the middle of the front wall and the middle of the rear wall of the corn seed box 61. Transparent semi-circular plates 66 are fixedly connected to the lower part of the front wall and the lower part of the rear wall of the corn seed box 61. A feeding pipe 67 is fixedly connected to the middle of the lower end of the corn seed box 61. The other end of the first drive motor 62 is provided with... An encoder 63 is installed. The corn seed box 61 is inserted and installed in the middle of the upper part of the frame 1. The inner sides of the two transparent semi-circular plates 66 are respectively close to the front and rear of the outer surface of the feed roller 64. The left end of the feed roller 64 is movably installed with the corn seed box 61 through a bearing. The two guide plates 68 are inclined at a relative 20-degree angle, and the bottom of the guide plates 68 is close to the upper part of the outer surface of the feed roller 64. The relative distance between the two guide plates 68 is the same as the diameter of the falling groove 65. The feed pipe 67 is the same as the inside of the corn seed box 61 and is fixedly installed with the telescopic pipe 76.

[0030] Through the above scheme: after the first drive motor 62 starts, it drives the feeding roller 64 to rotate inside the corn seed box 61. The seeds in the corn seed box 61 are guided by the guide plate 68, which is tilted at 20 degrees and whose bottom is close to the upper part of the feeding roller 64, and fall accurately into the dropping groove 65, which is matched with the distance of the guide plate 68. The transparent semi-circular plate 66 is close to the feeding roller 64 to prevent the seeds from leaking to the side. The seeds fall into the telescopic tube 76 of the sowing device 7 through the feeding pipe 67. The encoder 63 records the number of rotations of the feeding roller 64 to control the sowing amount. This realizes the orderly and accurate delivery of corn seeds, effectively avoids seed spillage and waste, and at the same time, the encoder 63 ensures that the sowing amount is accurate and controllable, providing a guarantee for the efficiency and standardization of corn planting, and improving the quality and efficiency of corn planting on film.

[0031] In this embodiment, the sowing device 7 includes a second drive motor 71. The output end of the second drive motor 71 passes through the frame 1 and is fixedly connected to an eccentric wheel 72. A crank rod 73 is sleeved on one side of the eccentric wheel 72. A connecting shaft rod 74 is inserted and installed on the side of the crank rod 73 away from the eccentric wheel 72. A planting plate 77 is fixedly connected to the right end of the connecting shaft rod 74. A telescopic tube 76 is fixedly connected to the middle of the upper end of the planting plate 77. Slider 75s are fixedly connected to the middle of the left and right ends of the planting plate 77. A pointed groove 78 is opened at the lower end of the planting plate 77. The second drive motor 71 is fixedly installed on the upper left end of the frame 1. The two sliders 75 are slidably connected in the groove 3 respectively.

[0032] Through the above scheme: after the second drive motor 71 starts, its output end drives the eccentric wheel 72 to rotate. The eccentric wheel 72 converts the circular motion into linear motion through the sleeved crank rod 73, which in turn drives the connecting shaft rod 74 to drive the planting plate 77 to move. The slider 75 on the planting plate 77 slides in the groove 3 of the frame 1, ensuring that its movement is stable and precise. When the planting plate 77 moves downward, the lower pointed groove 78 pierces the mulch film and inserts into the soil. At this time, the seeds in the telescopic tube 76 connected to the feeding pipe 67 fall into the soil to complete the sowing. Subsequently, the second drive motor 71 drives the planting plate 77 to move upward to reset, preparing for the next sowing action. Its beneficial effect is that by using the mechanical transmission structure of the eccentric wheel 72-crank rod 73, combined with the guiding design of the slider 75 and the groove 3, the planting plate 77 achieves stable and efficient reciprocating motion, accurately completing the actions of piercing the mulch film, sowing, and resetting. This effectively improves the efficiency of corn sowing on the film, reduces the intensity of manual operation, and ensures the quality and standardization of sowing.

[0033] It should be noted that this utility model is a corn planting machine on a film. First, the operator pushes the planting machine forward by holding the two push handles 5 at the upper rear of the frame 1. During the forward movement, the pressure rollers 4, which are movably mounted on the front of the left and right walls of the frame 1 via bearings, will compact the film on the ground to ensure that the film is laid flat on the ground. Then, when it is time to feed the seeds, the feeding device 6 starts to function. The first drive motor 62 starts, and its output end drives the feeding roller 64 to rotate inside the corn seed box 61. Under the action of gravity, the corn seeds in the corn seed box 61 will be fed by the two rollers. Guided by guide plates 68, which are inclined at a relative 20-degree angle and whose bottoms are close to the upper part of the outer surface of the feeding roller 64, the seeds fall into several dropping grooves 65 on the outer surface of the feeding roller 64. Since the relative distance between the two guide plates 68 is the same as the diameter of the dropping grooves 65, the number of seeds falling into the dropping grooves 65 each time is relatively fixed. At the same time, the inner sides of the two transparent semi-circular plates 66 are close to the front and rear of the outer surface of the feeding roller 64, respectively, which can prevent the seeds from scattering from the side of the feeding roller 64 and ensure that the seeds can fall smoothly through the feeding pipe 67. The encoder 63 set at the other end of the first drive motor 62 can accurately record the seeds. The number of rotations of the feeding roller 64 controls the amount of seeds dispensed, achieving precise feeding. The feeding pipe 67 is connected to the inside of the corn seed box 61 and is fixedly installed with the telescopic pipe 76 in the sowing device 7. The falling seeds will enter the telescopic pipe 76 along the feeding pipe 67. At this time, the sowing device 7 starts working, the second drive motor 71 starts, and its output end drives the eccentric wheel 72 to rotate. The eccentric wheel 72 drives the connecting shaft 74 to move through the sleeved crank rod 73. The connecting shaft 74 drives the planting plate 77 to move. The sliders 75 at the middle of the left end and the middle of the right end of the planting plate 77 are respectively located on the lower part of the left plate wall of the frame 1. The planting plate 77 slides within the groove 3 at the lower part of the right plate wall to ensure the stability of its movement. When the planting plate 77 moves downward, the pointed groove 78 at its lower end will pierce the mulch film and insert into the soil. At the same time, the seeds in the telescopic tube 76 will fall into the soil, completing one sowing action. Subsequently, the planting plate 77 moves upward under the drive of the second drive motor 71, detaches from the soil, and is ready for the next sowing. Through the coordinated use of the feeding device 6 and the sowing device 7, and with the operator continuously pushing the planting machine forward, the corn planting machine on the mulch film can complete continuous and precise corn sowing on the laid mulch film.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
