Description

A kind of crushed stalk scattering mechanism of all feeding-in combine

Technical field

The utility model relates to the crushed stalk scattering mechanism of a kind of harvesting machinery, particularly a kind of all feeding-in combine.

Background technology

Crops are remaining stalk in the ground after harvesting, normally stalk is incinerated, and when ploughing, the stalk ash is mixed in the soil as fertilizer sources then.Gathering in season, full of smoke when stalk burns in a lot of peasant households, shrouding the earth, resemble to the earth and cover with the dense mist of one deck.Air quality has been caused pollution.Near the farmland the airport particularly, when burning straw, the smogout landing ground of burning makes the pilot not see runway, has had a strong impact on the landing safety of aircraft.So country gives notice recently, forbid that at the field burning straw this has just proposed new requirement to the processing of gathering in the back stalk.As the manufacturing enterprise of agricultural harvesting machine, in harvesting, be crushed stalk a new problem how.

In order to address this problem, the breaking method of some grain header employing is at the plug-in stalk crasher of the outlet of thresher at present.This external hanging type cracker is owing to be subjected to the restriction in installation site and space, it is very big that volume can not be made, so the diameter of rotating part is also less relatively in the cracker, in order to improve the purpose that linear velocity reaches pulverizing, just require to improve rotating speed, so present external hanging type cracker, energy consumption and noise are all bigger.In addition, because the cracker installation site is higher, in the outlet of cracker, sprayed as the outlet of bullet by the short stalk after pulverizing from cracker, if beat on the person, very dangerous, if because of carelessness beat or other critical position may cause personal injury in addition at eyes.

The utility model content

The purpose of this utility model is to provide a kind of and can stalk can be pulverized in harvesting, threshing and the crushed stalk scattering mechanism of all feeding-in combine that energy consumption and noise are less, thereby overcomes the deficiencies in the prior art.

The technical solution of the utility model: a kind of crushed stalk scattering mechanism of all feeding-in combine.Comprise solid shafting and shell, on solid shafting, be connected with the pulverizing former, on the pulverizing former, the pulverizing ratch be housed, on the pulverizing ratch, be provided with pulverizing and refer to tooth, this pulverizing refers to that tooth is corresponding with the pulverizing cutter on the cased wall, pulverizes cutter and installs or be welded on the pulverizing plate; Outside at solid shafting is with hollow shaft, is connected with the threshing former on hollow shaft, and the threshing ratch is housed on the threshing former, is provided with threshing and refers to tooth on the threshing ratch; Solid shafting is connected with the minor sprocket that is contained in enclosure, and hollow shaft is connected with the hinge wheel that is contained in enclosure.

In the crushed stalk scattering mechanism of above-mentioned all feeding-in combine, on described shell, be provided with the stalk outlet, be provided with guide plate in the straw exit.

In the crushed stalk scattering mechanism of aforesaid all feeding-in combine, described pulverizing refers to that tooth can be finger-like tooth, tabular tooth or the cutter that has cutting edge.

In the crushed stalk scattering mechanism of aforesaid all feeding-in combine, the length of described solid shafting is greater than hollow shaft; The two ends of solid shafting are connected with shell through spring bearing; The threshing former at hollow shaft two ends holds with solid shafting through tubular axis and is connected.

Compared with prior art, the utility model can improve on the basis of existing all feeding-in combine or half-feeding combine, make existing grain header not only have the threshing function after the improvement and also have the pulverizing function, and the crushing straw after pulverizing can be shed in the ground uniformly.The utility model is being that the basis is that sheller unit with original grain header is divided into two sections when improving with existing grain header, and one section keeps original threshing function, and another section is as pulverizing function, and the rotating speed of pulverizing part is higher than the threshing part, promptly coaxial friction speed function.Because it is bigger to pulverize the radius of turn of pulverizing ratch partly, so the rotary speed of pulverizing ratch does not need to bring up to the rotating speed of prior art external hanging type cracker, just can reach the linear velocity of existing cracker, so the power consumption of cracker of the present utility model is more low in energy consumption than existing external hanging type cracker, the noise also external hanging type cracker than prior art is low, and simple in structure.Because the utility model is very succinct on the profile so housing can be made overall structure with on threshing part and the partly integrated axis of pulverizing, does not see inside if do not open, and does not see at all that from profile the utility model also has the pulverizing function.

Because the utility model increased guide plate in the outlet of grain header, can reduce the speed of the stalk ejection after the pulverizing on the one hand by guide plate, prevent from that crushing straw from spraying at a high speed to hurt sb.'s feelings; Also can the stalk after the pulverizing be sprayed uniformly to both sides or a side on the other hand by guide plate, when ploughing afterwards, can make crushing straw be mixed in the soil uniformly, and guide plate is not established in the exit of existing cracker, and the stalk after the pulverizing becomes delegation to be layered on the ground, later on when ploughing, stalk in the soil is inhomogeneous, can influence the growth of crops, and it is even also to need the people to go a stalk of embarking on journey to dial after pulverizing, the waste of manpower resource.Crushing straw can rot to become fertilizer and help the growth of crops from now in soil.
