Ditching machine for seeder

Abstract

The invention relates to a ditching machine for a seeder. The ditching machine provided by the invention comprises a seeder beam, a ditching machine and a handle column connected between the seeder beam and the ditching machine, and is characterized in that the upper end of the handle column is hinged on the seeder beam through a straight pin, and the lower end of the handle column is fixedly connected with the ditching machine; the seeder beam is provided with a front limited block and a rear limited block at the two sides of the handle column so that the tip of the ditching machine is under the straight pin when the handle column swings to the front limited block, and the swing angle of the handle column is 8-10 degrees when the handle column swings from the front limited block to the rear limited block; a regulation spring is additionally arranged; the upper end of the regulation spring is fixed on the seeder beam and positioned at the front end of the front limited block, and the other end of the regulation spring is hinged at the lower half part of the handle column; a wet soil backflow notch is arranged below the rear side of the ditching machine; the lower ends of a fertilizer guiding tube and a seed guiding tube are stretched into the ditching machine; the fertilizer guiding tube is positioned at the front end of the seed guiding pipe; and the fertilizer discharge port of the fertilizer guiding tube is lower than the seed discharge port of the seed guiding tube. By utilizing the ditching machine provided by the invention, ditching at one step and synchronous seeding at different depths of seed fertilizer are realized, and the working performance is excellent.

Description

technical field [0001] The invention relates to a ditch opener for a seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] As an important part of the seeder, the opener is commonly used as a fixed-position ditching method. Because the entry angle remains unchanged, this method can only meet the sowing requirements of arable land under single tillage conditions. For the current promotion of no-tillage For seeding, it is difficult to ensure the depth of trenching due to the fixed entry angle, which limits the versatility of the seeder application. Secondly, since most of the current sowing is the same application of seed and fertilizer, and the fertilization between rows is used, it not only increases the complexity of the structure of the planter, but also due to the small distance between the seed and fertilizer openers, often occurs in the no-tillage sowing process. The congestion of straw and weeds in front of the ditch has...

[0002] As an important part of the seeder, the opener is commonly used as a fixed-position ditching method. Because the entry angle remains unchanged, this method can only meet the sowing requirements of arable land under single tillage conditions. For the current promotion of no-tillage For seeding, it is difficult to ensure the depth of trenching due to the fixed entry angle, which limits the versatility of the seeder application

Secondly, since most of the current sowing is the same application of seed and fertilizer, and the fertilization between rows is used, it not only increases the complexity of the structure of the planter, but also due to the small distance between the seed and fertilizer openers, often occurs in the no-tillage sowing process. The congestion of straw and weeds in front of the ditch has seriously affected the operation quality of the planter, and sometimes it is even impossible to sow

In addition, because the inter-row sowing is far away from the plants, it also affects the utilization rate of fertilizers.

[0003] The shovel type ditch opener is currently the most commonly used ditch opener for domestic corn no-tillage planters. It has stable working quality, but it is easy to block; and it has poor adaptability to different ground conditions; although the disc type ditch opener does not exist Congestion problem, but due to its poor soil penetration, it is difficult to guarantee the trenching depth for different ground conditions
