Description

Technical Field

[0001] This utility model relates to the field of automatic sowing technology, specifically to an automatic sowing device for potato cultivation. Background Technology

[0002] To meet the needs of the potato industry, my country has introduced some potato planting machines from abroad, also known as potato planters. A potato planter is a type of planting machine that uses a planting system to plant tuberous seeds in an orderly manner in the ground.

[0003] When optimizing existing automatic seeding devices for potato cultivation, most improvements are made by adding a feeding component to achieve intermittent feeding, avoid material waste, and control the amount of material falling. For example, Chinese utility model patent application number CN202322546387.8 discloses "An Automatic Seeding Device for Potato Cultivation". This device includes a body, a soil crushing component, a first shell, a first chute, a second chute, a support base, a shovel head, a conveyor belt, a soil crushing roller, a connecting shaft, an eccentric wheel, a toothed plate, a first spring, a first motor, a first synchronous belt, a second synchronous belt, a second shell, a groove, a connecting plate, a soil screening trough, a feeding component, and a soil covering plate. The designed feeding component uses a material blocking roller to achieve intermittent feeding, which can accurately control the amount of material falling at one time.

[0004] Although the aforementioned automatic seeding device for potato planting has certain advantages in terms of adding a feeding component to achieve intermittent feeding, avoid feeding waste, and control the amount of feeding, it still has certain drawbacks: before planting potatoes, personnel need to loosen the soil and dig planting holes. It is impossible to use the device to complete the potato planting operation in one go, and the planting process is relatively labor-intensive. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides an automatic planting device for potato cultivation, which has the following beneficial effects:

[0019] 1. This automatic planting device for potato cultivation features a loose structure added to the front of the support frame. This loose structure serves as the foremost structural component of the entire device. A person holding a push handle can apply external force, allowing the device to move with the assistance of the wheels. Activating the servo motor causes the threaded rod to rotate back and forth, resulting in the up-and-down movement of the meshing block, which in turn moves the rake plate. With the engagement of the sleeve block and guide column, the rake plate consistently drives the rake teeth to move vertically up and down. This allows the rake teeth to apply chiseling force to different soil types, and the rake-like structure of the teeth effectively loosens the soil, creating planting holes for automatic potato planting. This avoids the device encountering hard soil and eliminates the need for personnel to pre-dig the planting holes.

[0020] 2. This automatic planting device for potato cultivation, by activating the drive turntable, causes it to rotate, which in turn drives the fixed roller to rotate, causing the orifice to move in a ring direction. The orifice structure of the orifice allows the potatoes inside the hopper to fall downwards through the orifice and into the drilled holes through the feed column. The structure of the soil-collecting plate allows it to push and cover the soil in time as the device moves, thus covering the holes where the potatoes are planted and completing the automatic potato planting operation.

[0030] Please see Figure 3-4An automatic planting device for potato cultivation includes a turning rake structure 13 comprising a rake plate 131, rake teeth 132, a meshing block 133, and a sleeve block 134. The rake teeth 132 are integrated with the rake plate 131 and are located at the lower end of the rake plate 131. The meshing block 133 is welded to the middle of the rear end of the rake plate 131. The sleeve block 134 is located beside the meshing block 133. The drive structure 15 includes a servo motor 151, a threaded rod 152, a bearing seat 153, a spring 154, a winding roller 155, a limiting track 156, and a frame 157. The output end of the servo motor 151 is connected to the upper end of the threaded rod 152, and the lower end of the threaded rod 152 is connected to the bearing seat 153.

[0031] Please see Figure 5 An automatic planting device for potato cultivation includes a feeding structure 2 comprising a hopper 21, a fixed feeding roller 22, a drive disc 23, a soil-gathering plate 24, a feeding column 25, and a through-hole 26. The lower end of the hopper 21 is connected to the upper end of the feeding column 25 and the two are internally connected. The drive disc 23 is fixedly connected to the side end of the fixed feeding roller 22 and is movably fitted.

[0032] In summary, by adding a loose structure 1 in front of the support frame 3 as the foremost structural component of the entire device, personnel can apply external force by holding the push handle 4. This facilitates the device's movement under external force, aided by the traveling wheels 5. Activating the servo motor 151 causes the threaded rod 152 to rotate back and forth, resulting in the up-and-down movement of the meshing block 133, which in turn causes the rake plate 131 to move up and down. With the engagement of the sleeve block 134 and the guide post 14, the rake plate 131 can always drive the rake teeth 132 to move vertically up and down, facilitating the rake teeth 132 to generate chiseling force on different soil types. Furthermore, the rake-like structure of the rake teeth 132 can also promptly... The soil is loosened, and planting holes are then dug in the ground to facilitate automatic potato planting. This avoids the device encountering hard soil and eliminates the need for personnel to dig the planting holes in advance. By activating the drive turntable 23, it rotates, causing the fixed roller 22 to rotate and the opening 26 to move in a ring. When the opening 26 moves to directly below the hopper 21, the potatoes inside the hopper 21 fall through the opening 26 and into the dug holes through the feed column 25. The structure of the soil-collecting plate 24 allows it to push and cover the soil as the device moves, thus covering the planting holes in time and completing the automatic potato planting operation.
