Description

Sowing mechanism of no-tillage fertilization seeder in rice stubble field

technical field

The utility model belongs to the field of agricultural machinery, and in particular relates to a no-tillage sowing mechanism of a no-tillage and fertilization seeder for rice stubble fields, which is particularly suitable for directly performing wheat no-tillage, fertilization and sowing operations on rice stubble fields without plowing. Complete ditching, fertilization, sowing and soil covering operations in a timely manner.

Background technique

No-tillage, fertilization and seeding are important contents of conservation tillage technology. Conservation tillage is a modern farming technique with straw covering the surface, less tillage and no-tillage sowing, and comprehensive control of diseases and insect pests. The development of conservation tillage is a revolution to traditional farming techniques and has attracted the attention of all countries. my country began to carry out the demonstration and popularization of this technology in the northern region in 2002. By the end of 2006, the northern provinces had promoted an area of 11 million mu. However, due to its special geographical conditions such as high mountains and low land, it is very difficult to promote mechanical technology. , so it is mainly done manually by manpower.

At present, the advanced planting technology promoted in agriculture and widely adopted by farmers in the south is no-till sowing and straw mulching and returning to the field. It is mainly realized by chemical weeding, manual seeding, and straw mulching and returning to the field, but there are the following problems : Because there is no suitable no-tillage planting machine, the technical realization can only be done manually. After a large number of rural laborers go out to work, the technology is difficult to meet the requirements, such as uneven seeding and non-standard stalk coverage; labor intensity is high; only using Straw covers the seeds, causing the germination rate to be greatly affected by the climate. In order to ensure the basic emergence of seedlings, increasing the sowing rate will increase the sowing cost. The above-mentioned problems will eventually affect crop yield and total yield, reducing crop income.

In order to solve the above problems, domestic also has the data introduction of relevant agricultural machinery operation technology, as the patent No. is CN200420085885.1 (stalk pulverizes and covers the land and no-tillage fertilization planter), and the patent No. is CN200520103523.5 (large ridge double row corn no-tillage planter). Seeding machine), etc., but some of these technologies are too complicated, the cost of machinery is high, and some are not suitable for the geographical conditions in the southern region at all, so there is no way to promote them.

Contents of the invention

The technical problem to be solved by the utility model is to improve the existing seeder according to the requirements of no-tillage sowing, so as to solve the problems of ditching, sowing and covering seeds in the stubble field. The technical scheme provided by the utility model is:

A sowing mechanism of a no-tillage and fertilizing seeder for rice stubble fields, including a ditch opener arranged on a vertical knife shaft, a soil retaining seeder fixed on a support frame, and a soil collecting rubber plate fixed on a fixed frame. The support plate determines the relative position and is connected as a whole, that is, the ditch openers are arranged on the vertical knife shaft according to the required gap distance between the ditch. The blade; the soil-collecting rubber plate is arranged behind the soil-retaining seeder.

The ditch opener and the soil retaining seeder are arranged in a row according to their center lines. The distance between the two is: the front end of the soil retaining seeder is close to the ditching blade that will not affect the ditching of the ditch opener. Operation.

The ditching blade is plugged into the knife box welded with the vertical knife shaft, and fixed with the knife box with a screw nut; one end of the vertical knife shaft is rotatably fixed in the bearing seat of the cantilever arm, and the other end is movable Connected in the bearing housing connected with the rotating sprocket.

The ditching blade of the ditch opener is in the shape of a cross around the shaft of the vertical knife that can open a ditch of 3-5 cm in width and 3-5 cm in depth.

The soil-retaining seeder fixed on the supporting frame of the soil-retaining seeder by screws is a plow-shaped hollow box with a sharp angle, and a seed delivery pipe is sleeved in the box.

The fixed frame is welded on the support frame, and the soil-collecting rubber plate is fixed on the fixed frame by screws, and its vertical position from the ground is higher than the position of the soil-retaining planter according to the requirement of covering soil; a pair of soil-collecting rubber plates are V-shaped The two lower parts of the array are composed of two rubber sheets with skirts, and the V-shaped mouth is forward.

The support plates for determining the relative positions of the ditch opener, the soil retaining seeder and the soil collecting rubber plate and connecting them as a whole are arranged at both ends of the seeding mechanism.

The implementation of the sowing mechanism of the above-mentioned technical scheme makes the utility model have the following advantages and positive effects: wide and narrow ditches meet the requirements of less tillage, and the width and depth fully meet the shallow sowing requirements of no-tillage. The role of the hard shell and root stubble can ensure that the seeds are sown on the bottom of the shallow ditch with good ground conditions, so as to ensure the reliable germination of the seeds; use the soil thrown back by the rotary tiller blade, and configure "V" behind the seeding device The "shaped soil collecting plate realizes the reliable covering of seeds and ensures the reliable emergence of seeds; it has a high anti-clogging (blocking grass) function, and cooperates with the standardized treatment of rice straw, which can efficiently realize rice straw covering and returning field. Harvest rice with the half-feeding combine harvester, simultaneously the stalks are chopped and evenly spread in the field (the half-feeding combine has this function), through about 40 days of natural aging treatment in the field (the straw in the evenly spread field can be better play the role of land protection and weed control), and the operation is smooth without blocking the grass, which not only meets the farming requirements, but also greatly reduces the labor intensity and improves the farming efficiency; because only less tillage is carried out, the cultivated area is only 40% One, and it is shallow plowing, so the plowing resistance is greatly reduced. Compared with the same type of shallow plowing seeder, the power is significantly improved, the fuel consumption is correspondingly reduced, and the energy saving and cost saving effects are obvious.
