Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a simple corn seeder. Background Art

[0002] As an important and widely cultivated grain, corn has strong drought resistance, cold resistance, and barrenness resistance, as well as excellent environmental adaptability. Therefore, the planting environment for corn is diverse, including large-scale mechanized planting in plains and fragmented planting in mountains, and the yield is guaranteed to a certain extent.

[0003] However, in the current small-scale corn planting process, due to regional space limitations, some large-scale sowing equipment cannot be used, so manual sowing is still the main method. However, manual work is labor-intensive, and secondly, work efficiency will gradually decrease with physical exhaustion, making it impossible to maintain high-efficiency planting. Although there are some auxiliary planting devices in the current existing technology, the devices are large in size, and the technical effects that can be achieved are only around corn sowing. The cost and practicality of use still need to be further improved. Utility Model Content

[0034] Working principle:

[0035] Example 1

[0036] During the sowing process, the handle frame 3 is held and the movable wheel 2 is used to move the entire device. After reaching the designated position, the first electric push rod 8 and the first gear 141 are started. The output end of the first electric push rod 8 drives the material box 6, the material guide pipe 4, the spiral drum 5 and the meshing output assembly 14 to move downward through the transition frame plate 9. At the same time, the first gear 141 engages the transmission brake servo motor 143 through the second gear 142, and then the brake servo motor 143 drives the spiral drum 5 to rotate synchronously. In this way, the rotating spiral drum 5 is used to automatically perform spiral drilling in the pre-selected rotary tilled planting soil layer;

[0037] After the spiral drilling is completed, close the first electric push rod 8, reset the material box 6, engage the output component 14, the spiral barrel 5 and the guide tube 4, close the first gear 141, and open the second electric push rod 11. The output end of the second electric push rod 11 drives the adjusting rod 10 to move downward as a whole until the movable plug 102 moves out of the interior of the guide tube 4. At the same time, some corn kernels inside the guide tube 4 will flow out of the guide tube 4 and enter the newly processed holes under the synchronous squeezing of multiple stirring rods 103, realizing automatic sowing. Then, hold the handle frame 3 and use the movable wheel 2 to move the entire device back and forth above the hole. Use the weight of the entire device to press the soil above the hole to seal and protect the corn, completing the final sowing operation. Subsequently, install the above steps and operate reciprocatingly in sequence.

[0038] Example 2

[0039] When sowing is completed, if it is necessary to irrigate the newly sown corn with water, water is added to the empty material box 6, and the inside of the guide pipe 4 is also in an empty state. At the same time, the solenoid valve in the diversion solenoid valve pipe at the top of the annular water tank 16 is opened, and the annular water tank 16 and the material box 6 are filled with water together. After a certain amount of water enters, the water addition is stopped, the handle frame 3 is held and the entire device is moved by the movable wheel 2. After reaching the previous sowing position, the second electric push rod 11 is started, and the output end of the second electric push rod 11 drives the adjusting rod 10 to move downward as a whole until the movable plug 102 moves out of the inside of the guide pipe 4. At the same time, the solenoid valve in the diversion solenoid valve pipe at the bottom of the annular water tank 16 is opened, and water flows into the sowing position through the guide pipe 4 to irrigate the corn in the soil layer with water. After a certain amount of water is output, the second electric push rod 11 is closed, the adjusting rod 10 is reset to close the guide pipe 4, and subsequently, according to the above steps, water is replenished and irrigated one by one according to the sowing trajectory.
