Abstract

A vibration type shallow-ploughing deep-loosening plough is a tillage equipment for shallow ploughing and deep loosening. The ploughing depth is 15-20 cm, and the loosening depth is 25-35 cm. The cultural method creates soil structure with loosend-compact zones, enhances soil fertility, stores water for preservation of soil moisture, and increases both production and income. The utility model is composed of a machine frame, a main plough body, a deep-loosening shovel, and a vibrating mechanism of the deep-loosening shovel. The deep-loosening shovel vibrates to reduce traction resistance and enhance the quality of the loosened earth. The utility model has the advantages of simple structure, reliability, and low cost.

Description

Vibration type shallow-ploughing deep-loosening plough

A kind of oscillatory type shallow reversing and chiseling plow belongs to the agricultural machinery category.

Traditional mouldboard plow mainly is made up of frame, main plough body etc.Dig in certain topsoil during work, topsoil easily forms the thick hard tillage pan of 8-12cm down.Permeable, ventilative, the waterlogging-resistant property of water conservation drought resisting of soil are degenerated.And adopt the dig method farming of interval subsoiling of shallow-layer, can break the soil structure that tillage pan is created actual situation and deposited.Advantages such as this methods of cultivation of evidence have the soil structure of improvement, retain and conserve soil moisture, increasing both production and income.But this methods of cultivation fail to be used widely aborning always, and main cause is not have desirable facility.Relevant report was introduced some repacking facility, but because complex structure, the tractive resistance practical application of failing greatly to obtain.On the other hand, the dark pine plough of the oscillatory type of using in the production now is to vibrate when making plough work by tractor motive power output shaft driving off-centred dipole.This structure need consume certain power, and structure is very complicated again, the cost height, thereby also rare in the actual production to using.

The purpose of this utility model is to provide a kind of simple in structure, reliable working performance, oscillatory type shallow reversing and chiseling plow that tractive resistance is little.

The utility model scheme realizes like this.With existing light-duty mouldboard plow as main plough body.Main plough body back dress deep soil loosing shovel.The deep soil loosing shovel handle is hinged on plow standard by support, the spade upper end by spring action on plow standard.Deep soil loosing shovel vibrates at longitudinal direction under soil resistance and spring force effect during work, thereby reduces tractive resistance greatly, improves the quality of loosening the soil.This structure does not need power source just can make deep soil loosing shovel when work vibration, have simple in structure, reliable operation, the characteristics that cost is low are applied in being convenient to produce.

The utility model is described in further detail below by accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Spacing adjustment screw, 8 bearing pins, 9 spade hinge supports, 10 spades, 11 shovel heads, 12 main plough bodys, 13 plow standards, 14 frames behind 1 spring support, 2 initial tension of spring adjustment nut, 3 spring bases, 4 springs, 5 locking nuts, 6 spade front limit adjustment screw, 7 spades.

In Fig. 1, plow standard 13 tops are fixed with spring support 1, the bottom is fixed with a spade hinge support 9, initial tension of spring is housed on the spring support 1 adjusts nut 2 and spring base 3, spring support 1 has an end of spring base 3 to be with spring 4, the other end of spring 4 is enclosed within the spade front limit and adjusts on the screw 6, spade front limit adjustment screw 6 and locking nut 5 are fixed on the upper end of spade 10 by screw thread, corresponding with spring support 1, the middle part of spade 10 is hinged on spade hinge support 9 by bearing pin 8, on the stent cover of spade hinge support 9 several circular holes are arranged, the upper right corner of support is fixed with spacing adjustment screw 7 behind the spade.

Shovel 11 a suffered soil resistance fluctuate within the specific limits during work.When soil resistance increases, shovel 11 swing backward, spade 10 rotates around bearing pin 8, and spade 10 upper ends are swung compression spring 4 forward.When a shovel suffered soil resistance reduces, spring 4 elongations, shovel 11 swing forward.Shovel 11 a suffered soil resistance constantly change during work, thereby also just constantly porpoise.

A shovel big I of 11 amplitudes is adjusted by adjusting initial tension of spring adjustment nut 2 change initial tension of spring, or changes the spring 4 of different-stiffness.The full swing scope of shovel 11 can be adjusted behind screw 6 and the spade spacing adjustment screw 7 and adjust pine soil depth and can realize with the hinge in spade 10 and spade hinge support 9 diverse location holes by changing bearing pin 8 by adjusting the spade front limit.

Owing to take such scheme, can under the situation that does not consume tractor power, realize vibrating subsoiling soil, improve the quality of loosening the soil, reduce tractive resistance, reach the purpose of surface ploughing and deep digging.
