Abstract

A straw returning machine for paddy fields comprises a connecting rack, a center support and a framework, a power machine is connected to the upper end of the connecting rack, the lower end of the connecting rack includes two connecting arms connected to the framework, two ends of the center support are connected with the framework and the connecting rack, two lateral bearing brackets are arranged at two ends of the framework, a center bearing bracket is arranged at the center of the framework, two half shafts are mounted on two sides of the center bearing bracket respectively, the outer end of each half shaft is mounted on the lateral bearing brackets, shovel-shaped blades are mounted on bodies of the two half shafts, two baffle plates are arranged on two sides of the root of each blade, and the upper end of each blade is slightly wider than the root of the blade. By means of the half shafts, the straw returning machine for paddy fields can better adapt to complex field forms, higher operating efficiency can be improved, the straw returning machine is simple in structure, portable, compact, easy in operation and low in failure rate, and straw paving efficiency is improved by means of the designed blades.

Description

The paddy field straw cutting apparatus

Technical field

The utility model relates to agricultural mechanical field, is specifically related to a kind of paddy field straw cutting apparatus.

Background technology

The straw-returning technology is the chief component of fertile soil engineering, facts have proved that straw-returning can improve soil structure, improves the soil organic matter, reduce environmental pollution.When crop harvesting, use crops straw pulverizing after associating special-purpose machinery directly will gather in the crops to turn over to bury and the field, have convenient, fast, advantage cheaply.Not only rob farming season; Solve a large amount of stalks of timely processing and gone back the field on the spot; Avoid rotting to burn bringing problem of environment pollution caused; And increase soil fertility with ground for large tracts of land, increase soil organic matter content, improve soil structure, culture fertility, raising farming output, created new road for development stable high yield agricultural.Straw-returning can be eliminated a series of harm that crop straw burning brings, and has reached to prohibit to burn purpose, has purified air; Improve ecotope, improved the physicochemical character of soil, improved soil fertility; Reach purpose highly efficient and productive, sustainable development; Stalk mechanization has simultaneously also increased agricultural machinery socialized service system ability in the field, has alleviated labour intensity, has showed the effect and the status of agricultural machinery.

Traditional paddy field straw cutting apparatus wheat straw efficient is lower, and manufacturing structure is complicated, heavy, and trivial operations breaks down easily, influences operating efficiency.

The utility model content

The utility model provides a kind of paddy field straw cutting apparatus, and this machine operation efficient is high, and is simple in structure, compact, and processing ease is inserted careless efficient height, and fault rate is low.

For realizing above-mentioned purpose, adopt following technical scheme:

A kind of paddy field straw cutting apparatus comprises link, central bracket and skeleton, and said link upper end is connected to dynamic power machine; The lower end is divided into two linking arms and is connected on the skeleton, and said central bracket two ends are connected with link with skeleton, and respectively there is a side bearing support at the skeleton two ends; There is a central support of bearing in central authorities; Two semiaxis are installed in central support of bearing both sides respectively, and its outer end is installed on the side bearing support, on said two semiaxis axle bodies blade are installed.

As the further improvement of the utility model, said blade is spade, and respectively there is a baffle plate shape root both sides, and the upper end is slightly wideer than root.

The design of the utility model semiaxis makes it more can tackle complicated field shape, like covered conduit etc., has guaranteed work; Can keep higher operating efficiency, and simple and light, compact, processing ease; Fault rate is low, and the design of blade shapes has improved slotting careless efficient.

Description of drawings

According to embodiment and accompanying drawing the utility model is done further explain below.

Fig. 1 is the utility model general structure sketch map;

Fig. 2 is the structural representation of part 7 among Fig. 1;

Fig. 3 is the left view of Fig. 2.

Among the figure:

1, link; 2, central bracket; 3, connector; 4, skeleton; 5, side bearing support; 6, semiaxis; 7, blade; 8, the central support of bearing; 9, baffle plate; 10, upper end.

Embodiment

To shown in Figure 3, provided a specific embodiment of the utility model, among the figure like Fig. 1; Link 1 upper end is connected to dynamic power machine, and the lower end is divided into two linking arms, is connected with skeleton 4 through connector 3; Central bracket 2 two ends are connected with link 1 with skeleton 4, and respectively there is a side bearing support 5 at skeleton 4 two ends, and there is a central support of bearing 8 in central authorities; Two semiaxis 6 are installed in the central support of bearing 8 both sides respectively; Its outer end is installed on the corresponding side bearing support 5 separately, on two semiaxis 6 axle bodies blade 7 is installed, and blade 7 circumference on the axle body of semiaxis 6 is interspersed; Blade 7 is spade, and respectively there are baffle plate 9 shapes the root both sides, and upper end 10 is slightly wideer than root, is pancake.

The design of the utility model semiaxis 6 makes it more can tackle complicated field shape, like covered conduit etc., has guaranteed work; Can keep higher operating efficiency, and simple and light, compact, processing ease; Fault rate is low, and the design of blade 7 shapes has improved slotting careless efficient.
