Description

A Seedbed Rotary Tiller

technical field

The utility model relates to the field of agricultural machinery, in particular to a seedbed rotary tiller and border builder.

Background technique

The seedbed is a small piece of land used to cultivate plant seedlings, divided into open-air seedbeds and indoor seedbeds. Seedbed bed building and plowing operations are important and basic links in agricultural production. The quality of the operation determines the growth of crop seedlings. The task of seedbed farming is to plow and trim the land, make the seedbed soil and farmyard manure, seedling fertilizer Mix well with anti-disease agents. To achieve the purpose of dredging the soil, increasing air permeability and water storage performance, covering weeds and stubble, and preventing pests and diseases; land preparation means that after arable land operation, there are still large soil clods or gaps in the arable layer, and the uneven surface is not conducive to sowing Or when the condition of the seedbed is not good, take the cultivation measures of breaking soil clods, leveling the ground, further loosening the soil, mixing soil fertilizer, improving the conditions of sowing and seed germination, and creating good conditions for the growth and development of crops.

At present, since there are no special bed-building and plowing machines for seedbeds on the market, the operations of seedbed bed-building and soil plowing mainly rely on manual bed-building and small tractors for plowing. The disadvantage of manual bed-building is that the bed surface is not The surface is not straight, the size is different, the seedbed soil is mixed with farmyard manure and seedling fertilizer unevenly, which cannot meet the requirements of agricultural technology, making it difficult to realize subsequent mechanical operations. In addition, bed building and plowing are labor-intensive and highly seasonal, so mechanical operations are urgently needed.

Contents of the invention

The technical problem to be solved by the utility model is to provide a seedbed rotary tillage and furrowing machine to solve the problems of not only building furrows, but also plowing and preparing soil, stirring soil and the like.

In order to facilitate the adjustment of the height of the rear scraper from the ground and the angle with the ground, so as to improve the effect of the scraper on the furrow surface, the front end of the tie rod in the present invention is processed with more than two holes for mounting pin A.

In order to change the distance between the rear ends of the side scrapers on both sides and the rear scraper conveniently by changing the positions of the furrow width adjustment bolts and nuts in the hole, and then change the size of the furrow surface, the rear scraper in the present invention is divided into two sections, left and right. The connection parts of the left and right sections are respectively processed with more than 2 holes, and the left and right sections are connected and fixed together by the furrow width adjusting bolts and nuts installed in the corresponding holes of the left and right sections.

Generally, the cross-section of the rear scraper can be selected according to the soil conditions and bed-building requirements, such as triangular, trapezoidal and other suitable profiles. In particular, in order to level and compact the furrow surface, the preferred cross-section of the rear scraper of the present invention is L-shaped. .

Beneficial effect

The seedbed rotary tillage and furrowing machine of the utility model can not only build furrows, but also realize operations such as plowing and soil preparation, soil mixing, etc., to build neat furrows, has a simple structure, is matched with various large, medium and small tractors, and reduces production costs. Significantly improve work efficiency. The advantage of the seedbed bed builder of the present utility model is:

1. Plowing, trimming, and crushing of soil blocks can be realized in sequence, so that the seedling bed soil, farmyard manure, seedling fertilizer, and disease control agents are fully mixed and evenly mixed, and the crop stubble can be chopped;

2. It can be effectively adjusted according to the agronomic requirements to build various flat border sizes required;

3. The device can be used for beet, rapeseed, saplings, and flower seedling nurseries to build borders;

4. Simple structure, easy operation and maintenance, and can be matched with various large, medium and small tractors.
