Adjustable crop furrow opener

Abstract

The invention provides an adjustable crop furrow opener which comprises a transverse rod, plough shares, a pull rod connecting base and a pull rod, wherein the transverse rod is a combined one; more than two plough shares which are parallel to one another and can be freely adjusted are arranged on the transverse rod; the plough shares are fixed on the transverse rod through screws; the soil penetration angles of the plough shares can be adjusted by adjusting the positions of plough share connecting plates in a sliding groove; one end of the pull rod connecting base is fixedly connected with the transverse rod, and the other end of the pull rod connecting base is in rapid insertion connection with the pull rod; and the pull rod comprises a rapid insertion rod and a handle, and the rapid insertion rod is fixedly connected with the handle. By adopting the adjustable crop furrow opener, the row span, seeding depth and row numbers can be controlled under artificial control conditions, and a plurality rows of furrows can be opened at one time, so that the working efficiency can be improved, and experimental seeding furrow opening can be completed with a relatively short time.

Description

technical field [0001] The invention relates to an adjustable ditch opener for crops, belonging to the technical field of ditching equipment for sowing experiments in crop plots. Background technique [0002] Before the 1990s, most of the plot experiments in my country's agricultural scientific research units used small hoes to open ditches, artificially spot seeds or spread seeds for sowing. very low. Until the new century, some units in our country introduced and developed a large number of test planters for small plots. Although they integrate ditching, seeding, fertilization and soil covering into one, there are still many deficiencies: first, they need supporting agricultural machinery for traction operations, which are relatively cumbersome. The cost is high; the second is that after the sowing operation, the tires of the planter will press deep imprints on the ground, resulting in runoff caused by rainfall during the growth period of the dryland plot test, often formi...

[0002] Before the 1990s, most of the plot experiments in my country's agricultural scientific research units used small hoes to open ditches, artificially spot seeds or spread seeds for sowing. very low

Until the new century, some units in our country introduced and developed a large number of test planters for small plots. Although they integrate ditching, seeding, fertilization and soil covering into one, there are still many deficiencies: first, they need supporting agricultural machinery for traction operations, which are relatively cumbersome. The cost is high; the second is that after the sowing operation, the tires of the planter will press deep imprints on the ground, resulting in runoff caused by rainfall during the growth period of the dryland plot test, often forming obvious differences in soil moisture; the third is that the plots are sown with different varieties When using materials, it is necessary to change seeds frequently, which is very easy to cause mixed species, which is time-consuming and labor-intensive

Fourth, the ditch is too wide and too deep, which will easily cause soil moisture to evaporate and cause experimental errors.

Fifth, the structure is complex, the cost is high, and the operation is complicated
