Straw cutting, fertilization and seeding all-in-one machine

Abstract

The invention relates to straw cutting, fertilization and seeding agricultural machines, in particular to a straw cutting, fertilization and seeding all-in-one machine. The straw cutting, fertilization and seeding all-in-one machine comprises a straw cutting machine and a seeding machine, a traction rod and an upper hanging rod of the straw cutting machine are connected with a traction shaft and a lifting rod of a tractor respectively, and a power shaft of the straw cutting machine is connected with a gearbox of the tractor. The rear portion of the straw cutting machine is connected with a combined seed and fertilizer drill. Cutters of the straw cutting machine correspond to the longitudinal positions of a fertilization plough leg and a seeding plough leg of the combined seed and fertilizer drill in a front-and-back mode. The machine has the advantages that the straw cutting machine is additionally arranged on the front portion of the seeding machine, two sets of cutters are firstly adopted to cut straw in a reverse-phase alternate mode, and therefore the corn straw can be cut into short sections with proper length conveniently. On the one hand, the nutrition of the straw can be kept; on the other hand, the cut straw in the land is short, and good conditions are created for seeding. In particular, the soil of the land with the straw cut is loose, the fastland soil moisture conservation effect is good, surface air drying of wet land is facilitated, and seeding of crops is facilitated. The fertilization and seeding quality is high.

Description

technical field [0001] The present invention relates to agricultural machinery, further to a planter, especially an integrated machine for collecting stalks, cutting stalks and sowing (fertilizing). Background technique [0002] At present, after wheat and corn are harvested, the stalks are usually returned to the field before sowing. In the prior art, the method of first rotary tillage and then sowing is generally adopted, which has certain defects: 1. After the straw is pulverized, it is mixed with the soil to form a mixed layer of straw and soil about 10 centimeters. In such a mixed layer In sowing, it is easy to sow the seeds on the straw, or the seeds are not completely covered by the soil, and eventually dead or weak seedlings may appear, resulting in reduced yield. 2. Due to the incomplete or incomplete removal of wheat stubble or corn stubble by the straw returning machinery, it has a serious impact on the subsequent sowing: the resistance of sowing increases, resul...

Problems solved by technology

In the prior art, the method of first rotary tillage and then sowing is generally adopted, which has certain defects: 1. After the straw is pulverized, it is mixed with the soil to form a mixed layer of straw and soil about 10 centimeters. In such a mixed layer Sowing, it is easy to sow the seeds on the straw, or the seeds are not completely covered by the soil, and eventually there may be dead seedlings or weak seedlings, resulting in reduced production

2. Due to the existence of the straw returning machinery, the wheat stubble or corn stubble is not removed or not completely removed, which has a serious impact on the subsequent sowing: the resistance of sowing increases, resulting in power consumption; cavitation is prone to occur during sowing, affecting Yield; uneven sowing

[0003] In order to solve this problem, some people have designed some processing methods, but the effect is not ideal
