Description

Technical Field

[0001] The present invention relates to the technical field of sowing, and more specifically to a polygala seeding machine. Background Art

[0002] Polygala is a perennial Chinese medicinal material with short plants and thin stems and leaves. It has poor competitiveness in field planting and is easily covered by other weeds. The largest investment in Polygala planting is weeding. Currently, Polygala planting adopts the mode of row sowing, with a row spacing of 23-25cm, a Polygala sowing width of 8-10cm, and a total width of Polygala sown per 1 meter of arable land of no more than 40cm. Ordinary people adopt this mode mainly to consider harvesting Polygala seeds. 30-40kg of Polygala seeds can be harvested per mu of land, which has good returns, but the labor input is very large, which is not suitable for large-scale planting of Polygala. Only 10-20 mu can be planted by family units, and the planting efficiency is low, and the degree of mechanization needs to be improved. Summary of the invention

[0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a Polygala tenuifolia seeder, which has a large hopper capacity and a large single sowing amount.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 6 As shown, a polygala seeding machine comprises a hopper 1, a front pressing wheel 7, a rear pressing wheel 8 and a chassis 11. The hopper 1 is fixedly arranged on the upper part of the chassis 11. The bottom of the chassis 11 is provided with a front wheel frame 12 and a rear wheel frame 13. The front pressing wheel 7 and the rear pressing wheel 8 are respectively fixedly connected to the front wheel frame 12 and the rear wheel frame 13. The lower part of the hopper 1 is connected and provided with a plurality of seeding devices 3. The seeding devices 3 are arranged at equal intervals below the hopper 1. The device presses the planting field that has just been rotary tilled by the front pressing wheel 7 to prevent the polygala seeds from falling into the soil gaps. The rear pressing wheel 8 presses the polygala seeds into the surface of the soil layer to prevent the polygala seeds from being blown away by the wind. The seeds are poured into the hopper 1 and sowed into the planting field through the seeding device 4.

[0026] Preferably, a plurality of seed pickers 2 are arranged in the hopper 1, and the seed pickers 2 are arranged at positions corresponding to the seed placers 3, and a diversion platform 3 is arranged between each seed picker 2. A gear-type seed picker similar to a wheat seeder is adopted, and 4 seed pickers 2 are provided, and the sowing amount per mu can be adjusted between 3-10 kg, so that it can be used not only to plant Polygala tenuifolia, but also to plant other crops such as Salvia miltiorrhiza.

[0027] Preferably, the seeding device 3 includes a seeding box 5 and a seeding tube 6. The seeding box 5 is fixedly arranged at the bottom of the hopper 1, the seeding box 5 is connected to the hopper 1, and the seeding tube 6 is connected to the bottom of the seeding box 5. Each seed picker 2 is equipped with two seeding devices 4, and the seeding devices 4 are used to seed backwards, a total of 8, and the end of the seeding tube 6 is duckbill-shaped, with a raised backflow line inside, so that the Polygala seeds can be distributed more evenly in the sowing width.

[0028] Preferably, a suspension mechanism 10 is provided on the chassis 11 above the front pressing wheel 7. The suspension mechanism 10 is used to connect the seed drill to the tractor.

[0029] Preferably, a shock absorber 14 is provided between the chassis 11 and the rear wheel frame 13, the top of the shock absorber 14 is fixedly connected to the chassis 11, and the bottom of the shock absorber 14 is hinged to the rear wheel frame 13. The shock absorber 14 plays the role of shock absorption and makes the rear pressure wheel 8 close to the ground.

[0030] Preferably, a gear 9 is provided on one side of the hopper 1, the axis of the gear 9 is connected to the seed picker 2, the gear 9 is connected to the rotating shaft of the rear pressing wheel 8 through a chain 15, and the gear 9 is driven to rotate through the rear pressing wheel 8.

[0031] Preferably, a chain guard 16 is provided outside the chain 15 , and the chain guard 16 is fixed on the chassis 11 and the rear wheel frame 13 by bolts.

[0032] Preferably, a front wheel scraper 17 is provided at the bottom of the chassis 11 , and the front wheel scraper 17 is arranged at an angle, with the scraper surface being arranged against the front pressing wheel 7 .

[0033] Preferably, a rear wheel scraper 18 is provided on the front wheel frame 12 . The rear wheel scraper 18 is inclined and the scraper surface is arranged against the rear pressure wheel 8 . The rear wheel scraper 18 has an opening on the setting route of the triangular cone 19 .

[0034] Preferably, triangular cones 19 are arranged along the circumference of the axis on the center line of the rear pressing wheel 8, and the triangular cones 19 are arranged equidistantly. The triangular cones 19 can increase the friction between the pressing rear wheel 8 and the ground when the device moves forward, ensuring the normal rotation of the pressing rear wheel 8, and avoiding the non-rotation caused by the dragging or failure of the pressing rear wheel 8, thereby affecting the rotation of the gear 9 and affecting the work of the seed picker 2.

[0035] The hopper 1 is 1.1m long, 0.3m wide, 0.4cm deep, and has a capacity of 132 liters. It can hold 100 kilograms of Polygala seeds. Once the material is loaded, it can continue to work for more than 10 mu, which greatly saves time. The front pressing wheel 7 is 1m wide and 0.4m in diameter, and the rear pressing wheel 8 is 1m wide and 0.4m in diameter. During the sowing operation, the seeds are loaded into the hopper 1, and the device is connected to the tractor through the suspension mechanism 10. The forward movement of the tractor will drive the device to move forward synchronously. Due to the rotation of the pressing rear wheel 8, the seed picker 2 is driven to work, and the seeds are evenly placed below and evenly sown on the ground along the seed box 5 and the seed tube 6. The sowing density of this device is high. Polygala can obtain population advantage by increasing the population density, inhibit the growth of weeds, and reduce the cost of weed control. At the same time, as the density increases, the yield per unit area of ​​Polygala can also be increased, killing two birds with one stone. The sowing width of this seeder is 1 meter, the seed amount per mu is 4kg, and the density is 8 plants / square decimeter; it can completely form a population advantage.

[0036] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
