Description

A traction ditching system for combined live broadcast machine

technical field

The invention relates to the technical field of farmland ditching equipment in agricultural machinery, in particular to a traction type ditching system of a combined live broadcast machine, and focuses on solving the problem that the ditching resistance of the combined live broadcast machine is large and the power of the tractor cannot be effectively utilized when the ditch is opened. problem, the system can also be used for ditching operations of other farm machinery.

Background technique

There is a lot of rain in the southern part of our country. When planting, it is generally necessary to open a box ditch every few rows to facilitate drainage or for irrigation in case of drought. There are two main methods of mechanical ditch opening: one is to open the ditch first and then sow. This method uses different machines to complete the ditch opening and sowing operations successively, which is time-consuming and labor-intensive, and causes repeated pressure on the ground by the machine. It is solid, and the original ditch pattern may be destroyed during sowing; the other is to use a combined operation seeder to complete the opening of the ditch while sowing. At present, there are mainly two ways to open the ditch of the domestic combined operation seeder: one is to smash the soil with a rotary tiller and then use a soil clearing shovel to clear out the complete ditch pattern. This method has a relatively neat ditch pattern, but it needs the power output shaft of the tractor to provide power. A gearbox is used to transmit power to the rotary tiller shaft. Generally, a rotary tiller with a seed bed is required, resulting in a complex structure and heavy weight of the whole machine. Equipped with a powerful tractor. The other is to rely on the traction force of the tractor and use a double-sided plow to open the ditch. The structure of the whole machine using this method is simple and light in weight, but the ditch shape is not neat enough, and the ditching resistance is relatively large, and the power consumption is high.

Contents of the invention

The purpose of the present invention is to overcome the technical defects of the existing ditching machines, aiming at the problems that the power of the tractor cannot be reasonably utilized when the combined seeder is opening the ditch, and the ditching resistance is large, and the ditch type is not easy to ensure, etc., to provide a stubble breaking machine. The traction furrowing system is composed of plow before furrowing and plow after soil clearing and shaping.

The present invention is realized through the following technical solutions:

A traction type ditching system used in conjunction with a direct seeding machine, two front plows (13) are symmetrically installed in front of the side plate (14) of the planter, and two front plows (13) are symmetrically installed behind the side plate (14) of the planter The rear plow (12); the front plow (13) is a single-sided plow plow, which includes a welded front plow post (1), a front plow face (2), a front plow side plate (3) and The front plow bottom plate (4), the front plow side plate (3) is in a straight line with the forward direction, the front plow surface (2) is biased towards the inner side of the box surface; the rear plow (12) includes a welded one-piece rear plow Plow column (5), rear plow plow surface (6), rear plow dividing soil plate (8), rear plow side plate (7) and rear plow bottom plate (9), the working curved surface of described rear plow (12) and the forward The direction is at an angle of 20 to 30°; the front plow (13) and the rear plow (12) are respectively connected to the fixing seat (11) by bolts; the fixing seat (11) is welded to the planter side plate ( 14) above; 3 installation holes are reserved on the front plow column (1) and the rear plow column (5), and the installation height can be adjusted (the installation holes can be matched with the holes of the fixing seat to adjust the installation height of the plow) .

In the present invention, the element line angle of the plow body curved surface of the front plow is 40°-45°, the ratio of the guide curve height h to the opening L is 1.7-1.8, and the plowing angle of the plow blade is 25°-30° , the angle between the tangent line at the two ends is 110°～120°.

When working, under the traction force of the tractor, the front plow breaks stubble, raises soil, crushes soil, and turns over soil to form a flat ditch bottom and a certain ditch width; At the same time, it plays a shaping role in the extrusion of the groove wall. The plow body combination on both sides goes back and forth once to open a complete trapezoidal ditch.

The beneficial effects of the present invention are:

1. The present invention consists of two sets of front plows and rear plows. The front plow breaks stubble and ditches, and the rear plow clears the soil for shaping. The furrows are neat and effective;

2. The front plow of the present invention is a single-sided conventional plow, which is easy to enter the soil and has low resistance to ditching;

3. The invention relies on the traction force to open the ditch, which reduces the weight of the whole machine compared with the rotary tillage ditching, rationally utilizes the power of the tractor, and effectively reduces power consumption.
