Description

Technical Field

[0001] The invention relates to the technical field of seed drills, in particular to a hole-seeding type garlic sprout seed drill. Background Art

[0002] Garlic, a key cash crop, has a significant impact on subsequent growth and yield during its sowing process. Traditional manual sowing methods are not only extremely inefficient and labor-intensive, but also, crucially, make it difficult for operators to precisely control the orientation of each garlic clove during continuous operation. They must be placed in the soil upright, with the bud tip facing strictly upward. Improper sowing can directly lead to delayed seedling emergence, missing seedlings, broken ridges, and weak seedlings, ultimately severely reducing yield and quality. To replace manual sowing, a variety of garlic sowing machines have emerged on the market. While these machines have made some progress in enabling on-demand sowing and improving efficiency, they suffer from fundamental deficiencies in addressing the core agronomic requirement of garlic sowing: correct bud sowing. Existing machines generally lack effective and reliable control mechanisms for the orientation of garlic cloves during the process of picking up garlic cloves from the seed box, transporting them to the sowing site via a conveyor, and finally releasing them into the seed furrow. Garlic cloves are prone to uncontrollable tumbling, deflection, and other changes in orientation during these steps, resulting in random positions when they land in the seed furrow. This results in a generally low and unstable correct budding rate, far from meeting the requirements for high-quality sowing. Therefore, we proposed a hole-seeding type garlic sprout seeder.

[0020] Among them, a connecting hose 22 is fixedly installed at the bottom of the external discharge block 310, and the bottom end of the connecting hose 22 is fixedly connected to the top of the drop tube 43, which is used to move the garlic seeds. The inner diameter of the connecting hose 22 and the inner diameter of the drop tube 43 are both about 1.5 cm to prevent the garlic seeds from rolling during the movement.

[0021] Among them, a handle 2 is fixedly installed on one side of the top of the frame 1, which is used for the user to control the equipment from the rear. A rotating mounting frame is provided on one side of the frame 1, and a covering roller 8 is rotatably connected to the inside of the rotating mounting frame to perform soil covering operations after sowing is completed.

[0022] In summary, when using the hole-sowing garlic bud seeder, before sowing, the garlic seeds are first placed inside the seed tray 33 in a posture with the buds facing upward, and the spiral seed guide groove 39 is used as a moving track. Then the seed tray 33 is closed, and the vortex spring body inside the inner vortex spring box 34 drives the inner rotating cover 35 to rotate, thereby driving the seed pusher 37 to rotate, so that the garlic seeds inside the seed tray 33 move to the position of the outer discharge block 310 and are clamped inside the outer discharge block 310. When the sowing is officially started, the engine 5 is started, and the engine 5 is used to drive the output end of the gearbox 6 to rotate, so that the second sprocket 10 and the third sprocket 12 drive the force to the outside, and through the cooperation of the second sprocket 10, the first sprocket 9 and the first chain 11, the central connecting shaft 71 is driven to rotate, thereby allowing the device body to move forward. At the same time, the third sprocket 12 drives 13 to rotate under the drive of the second chain 14, and the synchronous rotation of 13, the connecting shaft 23 and the fifth sprocket 15 drives the third chain 17 to generate displacement, and at the same time drives the sixth sprocket 16 to rotate, and through the rotation of the eighth sprocket 19 and the fourth sprocket 20 on the other side of the crankshaft 41, the seventh sprocket 18 and the rotating rod 31 are driven to rotate, and the rotating rod 31 When rotating, it drives the seed-discharging paddle 32 to rotate, and then pushes the garlic seeds inside the outer discharge block 310 into the interior of the connecting hose 22 through the seed-discharging paddle 32, and drops into the interior of the drop tube 43 through the connecting hose 22. At the same time, the crankshaft 41 rotates synchronously, and drives the synchronous connecting rod 42 to move. At this time, the synchronous connecting rod 42 is used to drive the second hinged lug 44 and the drop tube 43 to slide up and down inside the frame 1. When the drop tube 43 moves downward and contacts the ground, the duckbill clamp 49 is inserted into the soil, and then the trigger rod 47 immediately contacts the soil layer. At this time, the trigger rod 47 and the installation The ring block 46 and the sliding sleeve 45 cannot continue to move downward due to the obstruction of the soil layer. As the drop tube 43 continues to move downward, the two linkage rods 48 are lifted relative to the drop tube 43, so that the two duckbill clamps 49 are synchronously rotated outward under the drive of the linkage rods 48. At this time, the garlic seeds inside the drop tube 43 fall into the soil, and then as the position of the synchronous connecting rod 42 moves, the duckbill clamps 49 reverse and return to the initial state. At the same time, the drop tube 43 moves upward to complete the sowing, and then as the frame 1 continues to move, the covering roller 8 moves to the current position and covers the garlic seeds with soil.
