Description
Technical field
The utility model relates to a kind of agricultural machinery, relates in particular to a kind of maize harvesting machine straw chopping apparatus.
Background technology
The stalk that harvesting corn stays not only can hinder next round farming, also can affect the running of agricultural ploughing machine, processing method the most frequently used is at present burned exactly, but, the stalk with potential nutrition can be made to waste on the one hand by burning disposal stalk, on the other hand, the smog that burning produces can cause larger pollution to air, especially when large area is burned, its PM2.5 produced also may cause the decline of visibility, certain influence is caused to traffic, although have a lot of potential uses after crushed stalk, but its economy is still undesirable at present, therefore, straw-returning is the good selection of a stalk process.
Current stalk treatment facility is straw cutting apparatus mostly, and straw cutting apparatus has two kinds of application modes: one is after peasant harvests corn ear by hand, the corn straw smashing also field will stayed with straw cutting apparatus with tractor; Another kind is then in the middle part of corn combine or afterbody installs straw cutting apparatus, and at present, most of straw cutting apparatus all adopts hammer to grab formula design, and its consumption of power is large.
Utility model content
For all deficiencies of prior art, in order to solve the problem, now propose a kind of save power, save space, a kind of maize harvesting machine straw chopping apparatus simple for structure.
The technical solution adopted in the utility model is as follows:
A kind of maize harvesting machine straw chopping apparatus, comprise cutter shaft, installing plate assembly and stationary knife, described cutter shaft is arranged in the middle of installing plate assembly, described stationary knife to be arranged on above cutter shaft and to be fixedly connected with installing plate assembly, described cutter shaft is provided with 3-8 group moving knife, and described two adjacent groups moving knife is put mutually cutter shaft circumferential surface is straggly, described moving knife is set to a word blade, be provided with fixing hole, described moving knife two broadside is provided with blade, and one end of described cutter shaft is provided with driven sprocket.
Further, framework connecting plate is provided with above described installing plate assembly both sides.
Further, described stationary knife is made up of multiple ledger-plate word order.
Further, described moving knife is fixedly connected on cutter shaft by tool rest.
Further, described cutter shaft and junction, installing plate assembly both sides are provided with bearing.
The beneficial effects of the utility model are:
1, the utility model is simple for structure, has the feature of low cost of manufacture;
2, the utility model is arranged on below corn harvester, has joint space-efficient feature;
3, the utility model adopts moving knife to shred stalk with the mode that stationary knife is cut mutually, compares the hammer formula of grabbing and has the advantages that to save power.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the utility model moving knife structural representation.
Embodiment
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing of the present utility model; clear, complete description is carried out to the technical solution of the utility model; based on the embodiment in the application; other roughly the same embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of the application's protection.
A kind of maize harvesting machine straw chopping apparatus, comprise cutter shaft, installing plate assembly and stationary knife, described cutter shaft is arranged in the middle of installing plate assembly, described stationary knife to be arranged on above cutter shaft and to be fixedly connected with installing plate assembly, described cutter shaft is provided with 3-8 group moving knife, and described two adjacent groups moving knife is put mutually cutter shaft circumferential surface is straggly, described moving knife is set to a word blade, be provided with fixing hole, described moving knife two broadside is provided with blade, and one end of described cutter shaft is provided with driven sprocket.
