Description

A kind of rotation of stalk crasher crushes knife system

Technical field

The utility model belongs to agricultural machinery technological field, and the rotation for concretely relating to a kind of stalk crasher crushes Knife system.

Background technology

With the fast development of mechanization of agriculture, domestic agricultural product harvest realizes mechanization, most farming substantially Thing all has been realized in combining.Stalk disintegrating apparatus, the straw of crops are already provided with the large-scale united reaper in part Stalk will be crushed in harvesting process by stalk disintegrating apparatus, uniformly shed in farmland, realize farmland getting fat, avoid stalk Combustion phenomena, be advantageous to environmental protection.

But due to the conventional agricultural Model in China, the recoverable amount of small harvester is also very more, on these small harvesters Stalk disintegrating apparatus is also not provided with, causes harvested stalk to be retained in farmland, peasant household often uses burning straw Mode realizes straw-returning, is unfavorable for environmental protection.And the stalk disintegrating apparatus on existing large-scale united reaper is generally complicated, It is difficult to diminution design is carried out on the basis of original structure is retained, and manufacturing cost is also very high.In addition, existing stalk crushes Equipment was maximization design originally, and it cuts mainly crushes by the inertia of blade to stalk, when equipment is larger, knife Piece inertia is big, and crush force, which can meet to crush completely, to be required, and if by stalk disintegrating apparatus Scaling, blade inertia Just become very little, it is difficult to meet crushing straw requirement, crushing effect is very poor.

At present, in the market is well known that close crasher, and such mill structure is more complicated, cleans maintenance maintenance It is all very inconvenient, the service life and use state of pulverizer are influenceed, does not meet the requirement of contemporary Mechanization Development.

Therefore, applicant have developed a kind of stalk crasher suitable for small harvester, in the stalk crasher, straw Stalk crushing system is a very important part, the performance of its direct decision device, and rotates and crush knife system and be The primary clustering of stalk crushing system, its structure need to be rationally designed.

The content of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of rotation of stalk crasher Knife system is crushed, its is compact-sized, reasonable in design, and the stalk crasher for crushing knife system using the rotation has manufacturing cost The advantages of low, good crushing effect.

According to technical scheme provided by the utility model：The rotation of stalk crasher crushes knife system, including rotates rotor With several rotation crushing knifes mounted thereto, it is characterised in that：The crushing knife that rotates described in several is rotating rotor Equidistantly distributed on length direction, it is interspersed on the circumferencial direction for rotating rotor.

As further improvement of the utility model, the left end of the rotation crushing knife autorotation rotor described in several to the right side Hold and be divided into multiple knife groups in the way of every four are divided into one group, it is equal in a circumferential direction that four in each knife group rotate crushing knifes Even distribution；In two adjacent knife groups, the knife group positioned at right side biases 5~15 degree in a circumferential direction than the knife group in left side, And the biased direction all same of all knives group.

As further improvement of the utility model, in two adjacent knife groups, the knife group positioned at right side is than left side Knife group biases 10 degree in a circumferential direction.

As further improvement of the utility model, the edge width for rotating crushing knife caudad gradually becomes from tip It is narrow.

As further improvement of the utility model, the rotation crushing knife is made of stainless steel material.

As further improvement of the utility model, the rotation rotor includes roll body, and the rotation crushing knife, which is fixed, to be set Put on roll body, seal disc is provided with roll body both ends.

The utility model compared with prior art, has the following advantages that：The utility model rotation crushing knife is compact-sized, sets Meter is reasonable, and rotating set-up mode of the crushing knife on rotor is rotated can ensure that rotation crushing knife is uniform to stalk crushing material, Improve crushing effect.

Brief description of the drawings

Fig. 2 is the structural side view of the utility model embodiment.

Fig. 3 is the three-dimensional structure diagram of the utility model embodiment.

Embodiment

With reference to specific drawings and examples, the utility model is described in further detail.

As shown in FIG. 1 to 3, a kind of rotation of stalk crasher crushes knife system, and it is mainly by rotation rotor 1 and installation Several rotation crushing knifes 2 thereon are formed, and crushing knife 2 is rotated on the length direction for rotating rotor 1 described in several Equidistantly distributed, it is interspersed on the circumferencial direction for rotating rotor 1.

Rotating crushing knife 2 and use above-mentioned set-up mode, it is ensured that rotation crushing knife 2 is uniform to stalk crushing material, Improve crushing effect.

As shown in Figure 1, Figure 3, in the present embodiment, described rotation crushing knife 2, which amounts to, 32,32 rotations The left end of the autorotation rotor 1 of crushing knife 2 to right-hand member is divided into eight knife groups in the way of every four are divided into one group, in each knife group Four rotate crushing knife 2 and are uniformly distributed in a circumferential direction；In two adjacent knife groups, the knife group positioned at right side is than left side Knife group biases 10 degree, and the biased direction all same of all knives group in a circumferential direction.

As shown in Fig. 2 by using above-mentioned set-up mode, it is ensured that rotate whole rotation crushing knifes 2 on rotor 1 Almost it is circularly and evenly distributed on the projecting direction of side view, is advantageous to improve the crushing material uniformity.

As shown in figure 1, in the present embodiment, the edge width for rotating crushing knife 2 caudad becomes narrow gradually from tip.This Sample can ensure that rotating crushing knife 2 both has outstanding chopping result, has enough structural strengths again.Due in stalk material Inevitable that moisture, to avoid rotating the corrosion of crushing knife 2, the rotation crushing knife 2 preferably uses stainless steel material system Into.

As shown in Figure 1, Figure 3, in the present embodiment, the rotation rotor 1 includes roll body 1.1, and the rotation crushing knife 2 is fixed It is arranged on roll body 1.1, seal disc 1.2 is provided with the both ends of roll body 1.1.By the both ends of roll body 1.1 set seal disc 1.2, one Aspect, seal disc 1.2 can stop that stalk crushed material is entered in the bearing assembly of support roll body 1.1, ensure that bearing assembly is suitable Sliding operating；On the other hand, seal disc 1.2 can be fixedly connected with the casing of stalk crasher, make the installation of roll body 1.1 more steady Gu.
