Problems solved by technology

At present, the planting of grass (such as alfalfa) in mountainous areas and terraced fields in my country is mostly artificially sown. The efficiency of manual work is low, the amount of sowing is difficult to control and uneven, and the germination rate of seeds is low. Mechanized Harvesting of Pastures Creates Difficulties

Embodiment 1

[0034] Example 1, see Figure 1-6, a stepless precision seed drill for small hard seeds, including a frame 10 made up of a suspension device 11 and a load-bearing platform 12, a sowing depth adjustment device 20 and a walking ground wheel transmission system 30 are arranged below the suspension device 11. A seeding device 50 and a fertilizer discharge device 60 are provided above the load-bearing platform 12, and a ditch opener 80 and a soil covering suppression device 90 are provided below the load-bearing platform 12. The seeding wheel 55 of the seeding device 50 is provided with a spiral gradient groove 56; the ground wheel shaft 37 of the walking ground wheel transmission system 30 is provided with a single sprocket 32, the transmission chain 39 is connected to the double sprocket 36 provided on the fertilizer discharge shaft 62 through the single sprocket 32, and the second transmission chain 38 connects the triple sprocket 33,34,35 that is provided with on the seeding sh...

Embodiment 2

[0042] Embodiment 2 is the same as Embodiment 1, but the difference is that the triple sprockets 33, 34, and 35 of the transmission system 30 have teeth numbers of 40-45, 30-40, and 15-20 respectively, and the corresponding rotational speeds are 3.0-4.5r / min, 4.5~6.0r / min, 8~15r / min, by changing the number of triple sprocket teeth and fine-tuning the effective working length of the spiral gradient groove 56, the precision sowing of economic crops such as rapeseed is 0.5~0.6 kg / mu, 0.6 ~0.8 kg / mu, 0.8~1.0 kg / mu agronomic demand.

Embodiment 3

[0043] Embodiment 3 is the same as Embodiment 1, but the difference is that the triple sprockets 33, 34, and 35 of the transmission system 30 have teeth numbers of 32 to 42, 22 to 30, and 10 to 15 respectively, and the corresponding speeds are 2.8 to 3.8 r / min, 4.0~5.0r / min, 9~12r / min, by changing the number of triple sprocket teeth and fine-tuning the effective working length of the spiral gradient groove 56, the precision sowing of economic crops such as flax is 5.0~8.0 kg / mu, 8.0 ~10.0 kg / mu, 10~12 kg / mu agronomic demand.

Abstract

The invention mainly relates to an agricultural machinery, in particular to a structure of an alfalfa seeding machine. A small hard seed stepless precision drill comprises a rack consisting of a suspension device and a load bearing platform; a sowing depth regulating device and a traveling ground wheel transmission system are arranged below the suspension device; a seed metering device and a fertilizer feeding device are arranged above the load bearing platform; and an opener and an earth covering and pressing device are arranged below the load bearing platform. The small hard seed stepless precision drill is mainly characterized in that helical transition slots are arranged on seed metering wheels of the seed metering device; a single chain wheel is arranged on a ground wheel shaft of the traveling ground wheel transmission system; a drive chain is connected with a duplex chain wheel arranged on a fertilizer feeding shaft by the single chain wheel; and a second drive chain is connected with a triple chain wheel arranged on a seed metering shaft by the duplex chain wheel. The small hard seed stepless precision drill has novel design and compact structure, is simple and convenient to operate and has strong universality and good complete machine adaptability. Particularly, by the matching and regulation of the helical transition slots on the surfaces of the seed metering wheels and the duplex and triple chain wheels on the fertilizer feeding shaft and the seed metering shaft, the stepless precision seeding of small hard seeds can be implemented, the seeding quality and the working efficiency are improved, the yield of the agriculture and the grassland farming is ensured and the crop or grass mechanical harvesting working conditions are improved.

Description

Technical field: [0001] The present invention relates to the technical field of seeding equipment, in particular to a device for precisely sowing small hard seeds (such as alfalfa, rapeseed, flax, broad bean, etc.) in order to meet the requirements of different agronomic techniques, and especially relates to a small hard seed The structure of the stepless precision seed drill. Background technique: [0002] In my country, the soil types are complex and diverse, and there are many varieties of agricultural and animal husbandry seeds, with different sizes and shapes, and the sowing amount varies greatly. Forage hard seeds are generally small in size, light in weight, and smooth in skin. It is difficult to precision sow and requires high sowing machinery. Specifically: the requirements of the spreader are mainly to sow evenly, without missing sowing or reseeding, the sowing rate is accurate and adjustable, suitable for mixed sowing of multiple varieties of grass species, and c...
