Description

A multi-row plow no-tillage seeder

technical field

The utility model relates to a seeder, in particular to a multi-row plow no-tillage seeder.

Background technique

At present, the furrow plow and the seed pipe parts of the no-tillage planter are arranged separately. The furrow plow and the fertilizer discharge pipe are fixed on the frame of the no-tillage seeder, and the furrow plow and the fertilizer discharge pipe cannot be imitated. When sowing in furrows, the pipes of the seeding parts and the pressing wheels can be followed, but the plows and fertilizer pipes cannot be followed, resulting in the inconsistency of the furrowing and fertilization and sowing, resulting in a large difference in the depth of the seedbed, which makes fertilization difficult. It is difficult to control the seeding depth, the seeding effect is very bad, and the effect of solving the clogging problem is very poor. Chinese patent ZL200520144400.6 discloses a drive anti-blocking no-tillage seeder. When the seeder is working, it uses a rotary cutter to solve the problem of ditch plow blockage, and adopts double discs for ditching and sowing. During work, the furrow plow on the corn ridge works relatively normally, but the furrow plow in the furrow between the two corn ridges has a blockage problem, and the double-disc furrow seeder still has a blockage problem; the more serious problem is due to The furrowing plow is not an independent unit, but a whole row of fixed installations. Each furrowing plow and seeder unit cannot be copied independently, so the double discs in the furrow cannot cut off weeds and straw, but will plant Seeds are sown on weeds, stalks, and on the ground, so that the germination, emergence, and survival rate of the seeds in this row are low, and the seedlings burn or dry and die after emergence; seriously affecting the quality and effect of sowing. The imported no-tillage seeder uses the principle of cutting straws and ditching by facing a single disc directly; when the ground is hard and facing a single disc, it is difficult to enter the soil when the ground is hard, and when the ground is soft, it is impossible to chop weeds and straws, resulting in grass in the seedbed. More stalks affect seed emergence after sowing and burnt seedlings or dryness and withering after emergence; in high-yield areas of food crops, when there are many stalks exceeding the radius of a single disc, congestion still occurs.

Invention content:

The purpose of the utility model is to provide a multi-row plow no-tillage seeder, which solves the problem of blockage between the furrow plow and the seeder in the background technology, the inability of the furrow plow and the fertilizer discharge pipe to follow, and poor seeding quality and effect. technical problem.

There is a distance between the above-mentioned seeding pipe 9 and the outlet of the fertilizer pipe 8 . There should be a certain distance between fertilization and planting to ensure that there is a certain distance between fertilizer and seeds.

The above-mentioned furrowing plow 7 is within the effective function of the anti-congestion device 4 .

The distance between the lower end of the above-mentioned anti-crowding device 4 and the ground surface is -2cm～10cm.

The above-mentioned anti-congestion device 4 includes a cutter 4 and a cutter shaft 5 ; the cutter 4 is fixed or hinged on the cutter shaft 5 .

The utility model has the following advantages:

1) There is no congestion between the furrow plow and the seeder. The cutter on the cutter shaft is used to shave off the straw and weeds that hang on the furrow plow and the seeder, so as to ensure that there is no congestion between two adjacent furrow plows and fertilizer discharge and seeding pipes. Fewer weeds can ensure the quality and requirements of sowing.

2) Guarantee the ditching and sowing depth of uneven sowing fields. The furrowing plow and the seeder can be replicated independently, which can meet the requirements of furrowing and sowing depth in uneven sowing fields.

3) One machine with multiple functions. The seed fertilizer box is equipped with a variety of seed metering devices, which can be used for sowing wheat, corn, soybeans, grass seeds and other crops.

4) Save costs. One machine is multi-purpose, equivalent to wheat no-tillage seeder, corn no-tillage seeder, pasture no-tillage seeder and other equipment, with less investment, multiple functions, and cost savings.
