Description
Technical field
The utility model relates to agricultural machinery, further is straw cutting apparatus, the straw cutting apparatus of particularly making of the chopping principle.
Background technology
Behind crop harvesting, especially maize straw is very necessary at present, has so not only made reusing of energy source but also has guaranteed the fertile of soil, has also avoided the environmental pollution that causes because of burning straw simultaneously.Therefore, people have invented a variety of straw cutting apparatuss, and these equipment mostly adopt straw millstone, and the major defect of this device is: 1, power requires height, and the power that is mated requires height, and power consumption is large, and operating efficiency is undesirable; 2, operating cost is high, because power consumption is large, so excessive fuel consumption, operating cost is high; And because crushing effect is bad, many crushing and returning to field machine have to carry out two subjobs.3, affect the later stage farming, stalk toughness is large, and the stalk after surperficial quilt is pulverized is shape separated but still in each other's thoughts more, when formation " ball of string ", particularly soil are wet, very easily causes the plot to harden after the pulverizing, brings difficulty to the soil is cultivated whole with seeding operation; 4, affect the growth of the later stage such as wheat crop, the stalk of pulverizing is laid on ground, just as having spread carpet, is unfavorable for that soil absorbs sunlight; And the stalk canopy pine that becomes ball of string shape is unfavorable to wheat growth underground; 5, the straw utilization rate reduces, air-dry quickening after the crushed stalk, and nutrition is lost, and greatly reduces the straw nutrition availability.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of segmenting type straw cutting apparatus is provided, and it can cut into maize straw etc. the suitable pipe nipple of length, realizes straw-returning.
The purpose of this utility model realizes by following scheme:
A kind of segmenting type straw cutting apparatus, comprise frame, be arranged at line shaft and main shaft on the frame, frame connects axis of traction and the elevating lever of tractor by draw bar, it is characterized in that: main shaft is fixed on the frame by bearing, the two ends of main shaft arrange respectively belt wheel and plate wheel, an anti-phase eccentric shaft is set respectively on belt wheel and the plate wheel, the cutting knife that connects cutter bar and its underpart on the eccentric shaft by axle sleeve, the cutting knife rear portion is provided with axillare, axillare is by the axle cylinder lever connecting rod, and the rear end of pull bar is by the bottom of axle connection frame; Belt wheel connects power wheel by belt, and power wheel is arranged on the line shaft, and line shaft is fixed on the frame by bearing; Front bottom in frame also is provided with roller frame, is provided with horizontal pressure roller on the roller frame, is used for the relative compacting of stalk; Pressure roller can rise or descend fixing on roller frame.
The utility model also can further be realized by following scheme:
2 or 4 power wheels are set on the described line shaft, and line shaft central authorities are gearbox, and 2 or 4 power wheels distribute respectively at the gearbox bilateral symmetry, and 2 pairs or the 4 pairs of belt wheels and plate wheel are set on the corresponding main shaft, drive respectively four groups or eight groups of cutting knifes.
Described main shaft is discrete 2 or 4.
Described line shaft is divided into two sections, and two sections line shafts are connected with gearbox by universal joint separately.
The front of described frame and back respectively arrange two support bars, and support bar is the liftable fixed structure.
Described cutting knife is dull and stereotyped, is up-small and down-big trapezium structure, and the bottom is thinner or sword arranged.
The utility model adopts two anti-phase being arranged on the bent axle of cutting knife, alternately cuts and cuts stalk, thereby can conveniently maize straw be cut into the suitable pipe nipple of length.The beneficial effect of its generation is: 1, maize straw becomes pipe nipple, is conducive to the reservation of nutrition; 2, the plot soil of cutting is more loose, and to preserve soil moisture effective driedly, and it is air-dry that wetland is beneficial to the earth's surface, is convenient to cultivating of crops; 3, stalk becomes pipe nipple, and convenient employing plough is ploughed and buried.4, with respect to the straw cutting apparatus of traditional crush type, power consumption is few, and cost is low, and operating efficiency is high; After tested, also the field cost is the 50-60% of crushing and returning to field machine, and efficient can improve 40-60%(by a chopping and returning machine operation one time than crushing and returning to field machine).5, component wear is little, and maintenance cost is low.The utility model is simple in structure, is easy to make, can be preposition or rearmounted, changeable, can cooperate various driving power tractors.
