Hydraulic reversible ploughs: agricultural implements for land preparation prior to sowing

The hydraulic tilting plough, used with the tractor, is controlled by a twin distributor to lift and turn the plough. It is mainly used in agriculture for opening and breaking up soil, breaking up clods and ploughing out furrows so as to prepare for sowing, and the tilting plough has a two-way reversible function, saving time and fuel and being efficient and economical.

I. Structure of the hydraulic tilting plough

The main structure of the hydraulic tilting plough includes suspension, tilting cylinder, ground wheel mechanism, plough frame and plough body etc. Its detailed description is as follows.

    1. Suspension: with the tractor with the connection of the general use of three-point suspension, suspension and work host connected.
    2. Reversible cylinder: divided into reciprocating motion reversible cylinder and swinging reversible cylinder, reversible motion is precisely through the expansion and contraction of the piston rod in the cylinder to drive the plough body on the frame for vertical reversible motion, so as to achieve the purpose of alternately changing the working position.
    3. Ground wheel mechanism: The ground wheel is a dual-purpose mechanism with a screw to adjust the ploughing depth.
    4. Plough frame: there are left and right symmetrical plough bodies on the plough frame, the suspension device is set up with a flipping mechanism, the flipping mechanism is connected to the plough frame through the flipping shaft, the two-way hydraulic cylinder drives the flipping shaft to do 180 rotation through the flipping arm, the flipping shaft drives the plough frame to rotate, so as to achieve 180 reversal of the plough body.
    5. Plough body: is composed of a thick blade at the end of a beam, the reversible plough has two plough bodies, which are symmetrical at the top and bottom and have the same movement after reversible, which can significantly improve the efficiency and reduce the cost of work.

II. Types of hydraulic tilting ploughs

(i) Classification according to the type of hydraulic tilting plough shape

    1. Grid-bar tilting plough
      • The main body of the ploughshare is made up of a combination of grid bars, which makes it easy to repair and replace wearing parts. The upper and lower legs of the ploughshare are bolted together, so that damage to one part does not lead to the scrapping of other parts, greatly reducing the cost of repair and maintenance. For example, damage to the tip of the plough only requires replacement of the tip and does not involve damage to the plough frame.
    2. Shovel tilting plough (mirror type)
      • The main body of the ploughshare consists of a complete and relatively smooth plough surface, shaped like a mirror, with a monolithic structure and a low degree of disassembly, with some types having only the main force-bearing structure, the plough tip, removable or not, with the advantage that the overall strength factor of the ploughshare is high and the disadvantage that structural damage does not facilitate repair and replacement.

 

 

(ii) Classification according to whether the reversible plough is amplitude adjustable or not

The difference between a span-adjusting and a non-span-adjusting plough is the difference in strength of the plough body, the different working range and the different degree of operation.

    1. Different strengths of plough bodies
      • Width-adjustable reversible plough: the strength of the width-adjustable reversible plough is relatively high and it has a two-way reversible function, which makes it more efficient to use.
      • Non-rotating plough: the non-rotating plough is weaker and does not have a two-way reversible function.
    2. Different scope of work
      • Rotary plough: The rotating plough can be adjusted to suit the soil quality or the horsepower of the puller, within a certain range.
      • Non-adjustable reversible ploughs: Non-adjustable reversible ploughs cannot be adjusted to suit the soil quality or the horsepower of the puller, the width of the plough is fixed.
    3. Different levels of operation
      • Rotating ploughs: The rotating ploughs allow deep tilling of the land and the rotating ploughs have a better throughput in weedy areas.
      • Non-rotating ploughs: non-rotating ploughs can only be used for shallow tilling and, when shallow, they cannot work in areas with too many weeds.

(iii) Hydraulic tilting plough with secondary/side plough

    1. The role of the secondary/side plough: when the tractor using reversible plough in the ploughing, the secondary/side plough is mainly in the process of ploughing, can effectively bury the straw and weeds in the farmland, to play the effect of straw return and weeding. An ordinary tiller plough without a secondary plough can also bury straw and weeds to a certain extent when ploughing, but the secondary plough can significantly increase the coverage of buried straw and weeds. This is particularly important when ploughing or planting raw land. This is why tiller ploughs with secondary ploughs are so popular with farmers and agricultural operators.
    2.  Adjustments relating to tilting plough side ploughs

      • The ploughing depth of the secondary plough is generally adjusted according to the distance from the tip of the main plough to the tip of the secondary plough, this distance is also known as the ploughing depth. If it is too shallow, the soil will not be turned over and if it is too deep, the secondary plough will easily break.

      • Adjustment of ploughing depth: the depth of all secondary ploughs on a tiller must be the same, and when the depth of the main plough changes, the depth of the secondary ploughs also needs to be adjusted at the same time.

(iv) One-way and two-way hydraulic tilting ploughs

The two-way hydraulic tilting plough is based on the common one-way hydraulic tilting plough and is designed to make up for the shortcomings of the common tilting plough which can only plough from a single direction, repeatedly and many times, and is fully in line with the development requirements of energy saving and emission reduction, high speed and high efficiency.

III. Suggestions for purchase

First of all, when buying a hydraulic tiller, the first thing to consider is the efficiency, according to the area of land to be worked or according to the size of the existing tractor horsepower, choose a different number of ploughs, for example, only small horsepower tractor equipment or land area is small, it is recommended to choose a smaller plough such as 3-section plough; need to plough the land area is too large, you need to be equipped with a high horsepower tractor, as well as 4-section plough, 5-section plough or even larger ploughs. Different ploughs with different numbers of shares can have different working efficiencies.

Secondly, it is important to consider not only the number of sections but also the type of land to be ploughed to suit the implement. For example, if the land to be ploughed is of a hard soil type, then you need to choose a high strength, adjustable width plough; if the land to be ploughed is of a soft, sandy soil type, then you can choose a non-adjustable plough with a relatively low body.

Finally, the choice of a hydraulic tiller with or without a secondary plough can be made depending on the requirements for straw and weed retention in the land prior to sowing. In particular, it is advisable to choose a hydraulic tiller with a secondary plough as this can significantly increase the coverage of straw and weeds when preparing the land for planting.
