Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a wide-width densification seeder. Background Technology

[0002] In modern agricultural production, wide-span seeders are commonly used for sowing. During the sowing process, seeds are scattered into the soil by periodically opening and closing valves. However, when the sowing valves are closed, the seeds are easily squeezed, causing them to break and resulting in damaged seeds. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a wide-width density-increasing seeder to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this wide-width densification seeder to solve its technical problems is as follows:

[0005] A wide-width density-increasing seeder is provided, including a frame that can be mounted on a traction agricultural machine. A U-shaped bracket is fixedly mounted on the frame, and a sliding rod is fixedly mounted on the U-shaped bracket. Several sliding rings are fitted onto the sliding rod. The bottom of each sliding ring is fixedly connected to the upper end of a shovel handle, and a furrowing shovel is fixedly mounted to the lower end of the shovel handle. A seed box is fixedly mounted on one side of each sliding ring. A seed dispensing hole is formed at the top of the furrowing shovel, and a first mounting groove is formed within the seed dispensing hole. A first electric telescopic rod is fixedly mounted within the first mounting groove, and a first baffle is fixedly mounted on the first electric telescopic rod. A cavity is provided inside the baffle. Several air outlets are opened on one side of the cavity, and a through hole is opened on the other side of the cavity. A fan is fixedly installed on the shovel rod. A ventilation pipe is provided on the fan. The ventilation pipe passes through the shovel rod and the trenching shovel, enters the first mounting groove, and is inserted into the through hole. A second mounting groove is opened in the seed dispensing hole, located below the first mounting groove. A second electric telescopic rod is fixedly installed in the second mounting groove. A second baffle is fixedly installed on the second electric telescopic rod. The upper end of the seed guide tube is fixedly connected to the discharge port at the bottom of the seed box, and the lower end of the seed guide tube is fixedly connected to the seed dispensing hole.

[0006] Furthermore, a fertilizer box is fixedly installed at the bottom of the seed box, and the upper end of a fertilizer conduit is fixedly connected to the discharge port at the bottom of the fertilizer box. The lower end of the fertilizer conduit extends from the trenching shovel into the seed discharge hole and is located below the second mounting groove. An electric valve is fixedly installed on the fertilizer conduit.

[0007] Furthermore, an air guide hole is opened in the seed discharge hole on the opposite side of the first mounting groove. A vertical hole is opened above the air guide hole, and a column is provided in the vertical hole. A contact switch is fixedly installed in the CNC machine above the column. The contact switch is connected to the second electric telescopic rod and the electric valve through a circuit.

[0008] Furthermore, the tops of the first baffle and the second baffle are respectively wavy.

[0009] Furthermore, a sealing ring is fixedly installed inside the through hole, and the inner ring of the sealing ring makes sealing contact with the outer periphery of the ventilation pipe.

[0010] Furthermore, a groove is formed on the outer periphery of the slide rod, and threaded through holes are formed on the outer periphery of the slip ring, with bolts threadedly installed in the threaded through holes.

[0011] Furthermore, the outer periphery of the slide bar is marked with graduations.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a wide-width density-enhancing seeder. Before use, the spacing between the slip rings is adjusted according to the required planting density, and the frame is fixedly installed on the traction agricultural machinery. During tillage, furrows are opened using a furrowing shovel. During seeding, the blower is first started, causing air to blow out from the air outlet of the first baffle, which extends the first electric telescopic rod. When the first baffle moves, the seeds in the direction of movement of the first baffle are blown apart to avoid damage to the seeds. Then, the second electric telescopic rod retracts, and the seeds below the first baffle fall. Then, the second electric telescopic rod extends to close the seed discharge hole, and then the first electric telescopic rod retracts, thus completing one sowing cycle. The above process can be repeated to continuously sow seeds in the land. This device allows for convenient adjustment of planting density and avoids squeezing and damaging the seeds during sowing, reducing the probability of bad seeds during the sowing process.

[0014] 2. In this utility model example, a wide-width densification seeder can be used to apply fertilizer while sowing by switching on and off an electric valve, which facilitates seed growth.

[0015] 3. In the wide-width densification seeder of this utility model, when the first electric telescopic rod extends, it pushes the first baffle to move, blowing air into the air hole through the air outlet. This blows the column upward and into contact with the contact switch. When the contact switch is pressed, the second electric telescopic rod retracts and the electric valve opens, causing the seeds below the first baffle to fall, and fertilizer is also sprinkled downward. This continues until the fan is turned off, the column falls, the contact switch is no longer pressed, the second electric telescopic rod extends, and the electric valve closes, thus completing one sowing cycle. The first electric telescopic rod then retracts, ready for the next sowing cycle.

[0016] 4. A wide-width density-increasing seeder according to this utility model, through a wave-shaped structure, can move the seeds above when the first baffle and the second baffle move, so as to prevent the seeds from getting stuck in the seed discharge hole.

[0017] 5. In one example of this utility model, a wide-width densification seeder can seal the gap between the through hole and the ventilation pipe through a sealing ring, so that the air blown out by the fan can be smoothly discharged from the air outlet.

[0018] 6. In a wide-width densification seeder according to this utility model, the slip ring can be prevented from rotating on the outer circumference of the slide rod by inserting bolts into the slide groove. At the same time, tightening the bolts in the slide groove can fix the slip ring.

[0019] 7. In one example of this utility model, a wide-width density-increasing seeder can be easily adjusted to make the intervals between each slip ring the same by means of a scale. Attached Figure Description

[0029] In this embodiment, an air guide hole 24 is opened in the seeding hole 8 on the opposite side of the first mounting groove 9. A vertical hole 25 is opened above the air guide hole 24. A column 26 is provided in the vertical hole 25. A contact switch 27 is fixedly installed in the CNC 25 above the column 26.
