Description

Technical Field

[0001] The present invention relates to the technical field of agricultural seeding, and particularly to a quinoa furrowing and ridging seeding machine. Background Technique

[0002] Quinoa, native to the Andean mountains in South America, is the main traditional food of the Inca indigenous people. It has a history of more than 5,000 to 7,000 years of consumption and cultivation. Due to its unique nutritional value, it nourished the Inca nation, and the ancient Incas called it the "mother of grains". The colors of quinoa seeds are mainly white, black, red and other color systems, and the nutritional components are not very different. Among them, the white one has the best taste, while the black and red ones have relatively poor taste and smaller grains. The Food and Agriculture Organization of the United Nations believes that quinoa is a single plant that can basically meet the basic nutritional needs of the human body, and officially recommends quinoa as the most suitable whole-nutrition food for humans. The United Nations declared 2013 as the International Year of Quinoa to promote human nutrition and health and food safety and achieve development goals. At present, quinoa is usually sown by a seeding machine, which not only reduces the intensity of manual labor but also greatly improves production efficiency;

[0003] The following problems exist in the prior art:

[0004] In the prior art, a patent with the application number "202022198795.5" discloses a quinoa furrowing and ridging seeding machine, including a ridging box; a furrowing plow head installed at the front of the ridging box; a fertilizer applicator installed on the upper part of the ridging box; a plurality of seeding brackets evenly installed at the rear of the ridging box and a spoon-wheel type seed metering device installed on the seeding brackets; a pressing wheel installed at the rear of each seeding bracket; the front and bottom of the ridging box are open, and a row of inverted V-shaped ridging through holes are evenly opened at the rear of the ridging box. The above patent can solve the integrated requirements of quinoa furrowing, ridging and pressing to a certain extent, but the integrated seeding component cannot change the planting depth of quinoa and cannot meet the planting requirements of quinoa in different soils.

The moving seat 52 moves downward and drives the multiple components at the bottom to move downward, causing the connecting piece 56, the curved rod 57, and the ridging knife 3 to move downward, making the ditching depth greater.

[0039] Working principle

[0040] During the actual use process, after the ridging knife 3 ditches the soil, the quinoa seeds will flow through the feeding pipe 31 and be evenly discharged from the sowing holes 32 at the bottom of the ridging knife 3. During the process of the driving machine 1 driving the whole device to continue moving, the V-shaped leveling knife head 46 at the tail of the ridging knife 3 will cover the moist soil ridged by the ridging knife 3 on both sides back on top of the quinoa, covering it, and the deeper ridging groove can better protect the quinoa seeds, enabling them to obtain a more suitable growth environment and increasing the planting yield. After the ridging knife 3 ditches the ground, the quinoa seeds are sown from the sowing holes 32 through the existing seed metering device. The leveling knife prepares it at the tail. The two leveling knife heads 46 on both sides form a V-shaped structure, and the opening faces the ridging knife 3, which can refill the ridged soil into the ditch again. And a large-torsion coil spring 45 is arranged at one end of the leveling knife, driving the leveling knife to press down, having the effect of leveling and suppressing.

[0041] And during the leveling process, the miscellaneous stones will not damage the leveling knife head 46. When the leveling knife head 46 encounters a hard object, the force on the knife head will drive itself to rotate around the other end of the connecting rod 44 to avoid the hard object. During the rotation process, it will drive the rotating rod 43 to squeeze the coil spring 45 on the surface. After the leveling knife head 46 dodges the stone, it will move downward under the elastic force of the coil spring 45 on the surface of the rotating rod 43 and return to the ground to continue the leveling work. During the ridging and sowing process, the deeper ridging process and some miscellaneous stones will not damage the ridging knife 3. When the ridging knife 3 encounters a hard object, the force on the knife head will squeeze the curved rod 57 and the connecting piece 56 at the top. The connecting piece 56 is forced to enter the installation pipe 51. During the movement of the connecting piece 56, it will squeeze the telescopic spring 542 at the top. The telescopic spring 542 is forced to contract. After the ridging knife 3 dodges the hard object, it will move downward under the elastic force of the telescopic spring 542 in the pipe and continue the ridging and sowing work. This device further protects the ridging knife 3 and the leveling knife head 46.

[0042] A pressure sensor is provided. The ridging knife 3 is placed on the land for experimental ridging. When the ridging knife 3 squeezes the top curved rod 57 and the connecting piece 56, when the connecting piece 56 presses the top telescopic spring 542 and the wireless pressure sensor 53, the wireless pressure sensor 53 transmits the data signal to the external processing unit and displays it on the display screen. At this time, the depth of the soil and the magnitude of the force on the pressure sensor can be observed. The depth of the soil and the magnitude of the pressure on the display screen can be observed while trenching to determine whether it is necessary to change the trenching depth, and then its hydraulic components can be used to change the planting depth, while trenching, covering soil, and compacting are carried out.

[0043] So that the seeder can find the most suitable depth for quinoa during sowing. Turn the adjusting wheel 65. The adjusting wheel 65 rotates and drives the threaded rod 63 at one end to rotate around its own axis. The threaded rod 63 rotates and drives the hydraulic tappet 62 at its own end to enter the hydraulic cylinder 61. The hydraulic oil is pressurized and enters through the connecting hose 66 to the top of the installation pipe 51 to pressurize the moving seat 52. The multi-layer sealing ring 524 ensures that the hydraulic oil does not leak. The moving seat 52 moves downward and drives the multiple components at the bottom to move downward, so that the connecting piece 56, the curved rod 57, and the ridging knife 3 move downward, making the trenching depth greater, and vice versa. This is the hydraulic depth adjustment component to find the most suitable depth for quinoa planting, so that it obtains a more suitable growth environment and improves the planting yield. The hydraulic tappet 62 enters the hydraulic cylinder 61. The hydraulic oil is pressurized and enters through the connecting hose 66 to the top of the installation pipe 51 to pressurize the moving seat 52, thereby promoting the moving seat 52 to move downward and driving the multiple components at the bottom to move downward, so that the connecting piece 56, the curved rod 57, and the ridging knife 3 move downward, and then changing the ridging depth of the ridging knife 3. (Quinoa seeds are generally sown at a depth of 2 - 4 cm), and it can be adjusted according to this data to meet the needs of users.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
