Description

Crushed stalk is buried combine

The utility model relates to agricultural mechanical field, is mainly used in the maize straw field and directly pulverizes and bury simultaneously.

Some multiple operation straw cutting apparatuss appear in recent years in succession, as utility model patent: 88214950.4 and 89217085.9 two patents, a kind of facility that crushed stalk and root stubble are abolished that have have been proposed, its primary structure is that the crushed stalk rotor is preceding, the root stubble abolish after, pulverize rotor and reverse, the stubble removing knife roller just changes, the stubble removing knife roller buries, only 4～8 centimetres of working depth.Its major defect is pulverizing, breaking, buries, covers and can not once finish.

The purpose of this utility model provides a kind of crushed stalk, breaking, buries one step completed straw cutting apparatus.

The purpose of this utility model is achieved in that

It is by power transmission shaft 1, case 2, and middle driving box 3, side driving box 4, fence 5, rotary tillage rotor 6, the plough 7 that clears the way is pulverized rotor 8, nearside divider 9 compositions such as grade.After facility hang on tractor, the power of tractor motive power output shaft output is by power transmission shaft 1 input middle driving box 3, middle driving box is defeated by side driving box 4 after again power being divided into two tunnel, one tunnel deceleration, is defeated by the rotary tillage rotor after being slowed down once more by side driving box.Be defeated by after another road speedup and pulverize rotor 8.Power transmission shaft 1 is downward-sloping and pass and pulverize rotor 8, in the position that power transmission shaft 1 passes flail knife is not installed, separate to both sides with the stalk of nearside divider 9 feeding, pulverizing rotor 8 reverses, after crushed stalk, throw rotary blade roller 6 the place aheads backward along case 2, the rotary tillage rotor also reverses, and the rotor axle center is lower than the face of land makes the soil block of being cut in the moment of leaving the face of land initial velocity to the back upper place be arranged, and soil block, stalk and root stubble are rearward skimmed along case.When the soil block straw stubble that mixes moved to the fence place, stalk, root stubble and soil block were blocked by fence and along its inboard landing, small clod passes fence and dishes out, covers on the stalk.In order to make the native operation of diving of rotary tillage rotor, the soil that turns over side driving box the place ahead with the ploughing of clearing the way sinks casing, and the rotor axle center is positioned under the face of land.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is the utility model schematic diagram

Fig. 2 is the utility model drive mechanism figure

Describe concrete structure of the present utility model and operational detail in detail below in conjunction with Fig. 1, Fig. 2.

As shown in Figure 1 and Figure 2, the utility model is by power transmission shaft 1, case 2, middle driving box 3, side driving box 4, and fence 5, rotary tillage rotor 6, the plough 7 that clears the way is pulverized rotor 8, and nearside divider 9 parts such as grade are formed.

Power transmission shaft 1 is by two bearings in front and back.Two pairs of bevel gears are installed in the middle driving box 3, bevel gear 10 and 11 engagements, power is passed to pulverizing rotor 8 by second 15 by belt.Bevel gear 12 and 13 engagements, power is connected with side driving box 4 by the 3rd 14, three spur gears are installed in the side driving box 4 power is passed to rotary tillage rotor 6, pulverize the top of rotor and rotary tillage rotor 6 case 2 is installed, two rotors by bearing fixing on sidewall 16, case 2 rears dress fence 5, nearside divider 9 is installed in the centre position, the place ahead of case 2.Middle driving box 3 postposition, be installed on the crossbeam by bearing block, connect with the power take-off of tractor by power transmission shaft 1, power transmission shaft 1 is downward-sloping, 4～15 ° of gradients, and pass and pulverize rotor 8, in the position that power transmission shaft 1 passes the pulverizing cutter is not installed, separate to both sides with the stalk of nearside divider 9 feeding, rotary tillage rotor 6 is in the back lower place of pulverizing rotor 8, clear the way plough 7 design tilling depth α than the case of side driving box 4 at the bottom of to more than the big 10mm of centre distance γ of rotary tillage rotor 6, be positioned at below the face of land with the axle center of realizing the rotary tillage rotor.The plough 7 that clears the way is installed on the place ahead of side driving box 4, and its ploughshare blade line is lower than case bottom 5mm, by the kind of drive that Fig. 2 describes, has guaranteed to pulverize the reverse of rotor 8 and rotary tillage rotor 6.Thereby finish the technical scheme that the utility model proposes.

Advantage of the present utility model has: reduce owing to pulverizing, breaking, bury one-stop operation and finish (1) The operation number of times of tractor, thereby reduced soil packing, reduce operating cost; (2) 1 machines Tool replaces 2 or 3 facility operations, reduces the facility total input cost; (3) because crushed stalk same In time, directly ploughs and buries, and do not evaporate at the bright stalk moisture content of combined task, and imbedding behind the soil can fast rotting, The area, paddy field can be robbed farming season, robs season, the output of doing after improving; (4) adopt the soil of diving to reverse the work of burying Parts, tilling depth can reach 12～20cm, and it is good, low in energy consumption that stalk is buried performance; (5) intermediate transmission The case postposition can shorten drive path makes the implement structure compactness; (6) intermediate propeller shaft is downward-sloping one Angle has shortened the centre-to-centre spacing of side gear box, can reduce weight, save manufacturing cost.

Jiangsu Province's agricultural machinery is identified to stand and in 94 years this utility model has been carried out the transaction capabilities detection. Detect knot Really: the corn straw smashing rate (length＜100mm) is 96.2%, coverage rate 97.7%, Root stubble percentage of damage 87.3%.
