Description

Technical Field

[0001] The invention relates to the technical field of planting machines, in particular to a potato planting machine with hole opening and soil covering on film. Background Art

[0002] The main crop planted in Northwest my country is potato, which has high yield and can adapt to various complex environments. As the potato planting area in Northwest China gradually increases, the difficulty of manual planting also increases. In traditional planting, manual cultivation is usually used for planting processes such as trenching, sowing, and film laying. However, for large-scale planting, traditional planting operations are inefficient and labor-intensive.

[0003] In order to improve the efficiency of potato planting and reduce labor costs, at present, in the promotion and application of potato planters, the existing planters are generally large in size. However, generally, potato planting is mainly carried out on hill terraces, and the larger planters are greatly affected by the working environment.

[0004] However, the existing seeding machines have various seeding methods, such as the eye wheel type, the vertebral disc type, and the chain spoon type. When working, the seeds fall into the seeding and picking frame under their own gravity through the slope of the seed box, and finally fall into the seed trench by driving the seed picking frame to complete the planting. In this process, the size of each seed is not the same, and the number of seeds taken each time will also vary. Similarly, the seeds are placed into the seed trench through the seed picker, and the damage rate of the seeds will increase during the seeding process. At the same time, the existing potato planters on the market cannot accurately adjust the spacing between seed rows and the sowing depth. For the constraints of the potato planting environment and seed size, duckbill hole-drilling and seeding can better adapt to the working scene, so we proposed a potato film-top hole-drilling and soil-covering planter to solve the above problems.

The boss guide rail 9-7 cooperates with the duckbill movable bearing 9-9-4 on the duckbill acupuncture device 9-9 for movement;

[0047] By adopting the above technical solution, when the first hexagonal transmission shaft 8 transmits power to the third transmission shaft 9-2, the third transmission shaft 9-2 drives the disc base 9-10 to rotate, and as the disc base 9-10 drives the connecting plate 9-6 to rotate, the connecting plate 9-6 drives the duckbill hole-punching device 9-9 to rotate, and the duckbill always remains in a downward state in a fixed direction position.

[0048] In this embodiment, the duckbill hole-punching device 9-9 includes a fixed sleeve 9-9-6, an inoculation port 9-9-1, a movable duckbill 9-9-2, a movable duckbill 9-9-3, a reset spring 9-9-5 and a duckbill movable bearing 9-9-4.

The third sprocket 8-1 and the fourth sprocket 8-3 form a chain drive through a chain, and the fifth sprocket 8-2 and the sixth sprocket 8-4 form a chain drive through a chain.

[0056] By adopting the above technical scheme, the suspension device 2 of the machine is connected to the three-point suspension at the rear of the tractor. When the tractor starts to move forward and the ground wheel contacts and rotates with the working ground, the second transmission shaft 6-2 is driven to rotate. At the same time, the second transmission shaft 6-2 transmits power to the first transmission hexagonal shaft 8 through a chain drive to make it rotate. The first transmission hexagonal shaft 8 transmits power to the third transmission shaft 9-2 through two sets of chain drives in the middle. At the same time, two sets of duckbill hole-piercing devices 9-9 start to move. The outer side of the third transmission shaft 9-2 transmits power to the seed potato fan disc planting device 13 through a chain drive. The power is converted by the bevel gear reducer 10-2 on the seed potato fan disc planting device 13 and drives the movable fan disc 13-1 to rotate, thereby transmitting power to each component of the machine.

[0057] The working principle of the present invention is to install the film on the film hanging rod 4-2 of the film covering device 4 and unfold it for a distance, then cover the unfolded part of the film with soil to prepare for the subsequent film covering operation, load the prepared seed potatoes into the seed dropping disc box 13-2 of the seed potato fan disc seeding device 13, ensure that the seed potatoes can be smoothly sent to the seed potato seed discharge port 13-3 in the subsequent operation, connect the planter with the three-point suspension at the rear of the tractor through the suspension device 2, start the tractor to make it start to move forward, and as the tractor pulls the planter forward, the film covering device 4 starts to work. The film on the film hanging rod 4-2 is driven by the film covering device 4, and the film spreading rod 4-3 gradually unfolds the film on the surface of the moving soil layer. At the same time, under the action of the spring 4-5, the film pressing wheel 5 can always be close to the ground along with the terrain, and the film is tightly pressed against both sides of the ridge surface during the moving process to ensure that the film covers tightly and flatly. At this time, the ground wheel 12 contacts the working ground and rotates accordingly, and the power is transmitted to the walking ground wheel device 6. The rotation of the ground wheel 12 drives the second transmission shaft 6-2 in the walking ground wheel device 6 to rotate, and the first sprocket 6 on the second transmission shaft 6-2 -3 forms a chain drive through the chain and the second sprocket 6-4 at the hexagonal bearing 6-9 of the ground wheel, and transmits power to the first transmission hexagonal shaft 8. The first transmission hexagonal shaft 8 transmits power to the third transmission shaft 9-2 of the double-disc rotating acupuncture device 9 through the chain drive of the third sprocket 8-2 and the fourth sprocket 8-3, the fifth sprocket 8-3 and the sixth sprocket 8-4. The third transmission shaft 9-2 drives the disc base 9-10 to rotate, and then drives the duckbill acupuncture device 9-9 connected to the disc base 9-10 to rotate, and the duckbill always remains in a vertical downward state.

[0058] When the duckbill hole-punching device 9-9 rotates, the duckbill movable bearing 9-9-4 moves along the boss guide rail 9-7. When moving to the highest point, the duckbill piercing device 9-9 is squeezed by the boss guide rail 9-7, and the movable duckbill 1 9-9-2 and the movable duckbill 2 9-9-3 slowly open. When moving to the highest point, the optimal position for soil seed discharge is reached and the duckbill is opened to the maximum extent. At the same time, the third transmission shaft 9-2 of the double-disc rotary piercing device 9 transmits power to the bevel gear reducer 10-2 of the seed potato fan blade disk seeding device 13 through the matching sprocket. The bevel gear reducer 10-2 drives the fourth transmission shaft 13-4 to rotate, and the fourth transmission shaft 13-4 further drives the movable fan blade disk 13-1 to rotate. During the rotation of the movable fan blade disk 13-1, when the seed potato between the two blades is moved to the seed potato seed discharge port 13-3, the seed potato falls therewith, and just falls into the inoculation port 9-9-1 when the duckbill piercing device 9-9 is in the optimal position for soil seed discharge (that is, the duckbill is opened to the maximum extent), completing the seeding action.

[0059] Before the planting machine works, the position and angle of the covering plate 7-1 can be adjusted by moving the movable fixing part 7-3 of the covering device 7, and the two covering plates 7-1 can be adjusted to a suitable distance, and the centers of the two covering plates 7-1 are both facing the inside of the machine. When the machine continues to move forward, the adjusted covering plates 7-1 will gather the soil on both sides of the ridge surface to the sowing area, thereby realizing the covering process of the hole sowing opening on the film, and completing a series of operations of the entire potato planting.
