Abstract

The utility model discloses an opposite rolling type seed-cutting mechanism for sugarcane plant. The seed-cutting mechanism mainly comprises a pair of rollers and four cutters which are distributed up and down and are mounted on a bearing seat, wherein two cutters are symmetrically mounted in the radius direction of each roller; the end parts of the two rollers are externally meshed through two same gears to realize synchronous rotation; and one roller is connected with a hydraulic motor. By using the seed-cutting mechanism, the cutting stability and the cutting accuracy are improved, and meanwhile, the seed-cutting mechanism has a certain function of preventing a head from being broken. By using the seed-cutting mechanism, a seed-cutting function can be realized alone, and the seed-cutting mechanism can be mounted on a sugarcane planter to assist the sugarcane planter to realize the functions of synchronously cutting sugarcane seeds and planting.

Description

A kind of cane planting relative rolling type is cut kind of a mechanism

Technical field

The utility model relates to the sugarcane mechanization field of planting, and specifically a kind of cane planting relative rolling type is cut kind of a mechanism.

Background technology

The sugarcane cutting technique, in sugarcane mechanization results and mechanized cultivation operation, it all is the technical barrier that is difficult to break through, because it is improper to cut, cause easily sugarcane to break head, sugar runs off, especially in plantation, sugarcane kind broken head when cutting causes the loss of sugar and moisture can have a strong impact on the germination of sugarcane kind and the early growth of sugarcane seedling.For this reason, people have carried out a large amount of research work for the sugarcane cutting technique, and two kinds of typical sugarcane cutting modes are arranged at present: disk cutting and linear reciprocation cutting.Wherein the theory of disk cutting is comparatively ripe, is widely used on the harvesting sugarcane machinery of Multiple Type.But disc cutter is in cutting process, and a blade can't cut off sugarcane, but want a plurality of blades, repeatedly cut, again because sugarcane has rectilinear motion with respect to disc cutter, so repeatedly the cutting position of cutting is not on same cross section, this has just caused a serious broken phenomenon.In addition, the linear reciprocation cutting is vertically just to cut, and not only be difficult to determine direct tangential force, and cutting speed is little, and required direct tangential force is large, and hydraulic-driven rated power requires large, the while complex structure, and transmission and speed control difficulty thereof, cutting efficiency is low.This shows that above-mentioned two kinds of cutting modes all should not be applied on the sugarcane kind cutter sweep of sugarcane planting machine, the cutting mode of being badly in need of a kind of novel practical satisfies the specification requirement of sugarcane planting machine sugarcane kind cutting.

The utility model content

Technical problem to be solved in the utility model provides a kind of energy and improves stability and the accuracy of cutting, has simultaneously certain anti-cane planting relative rolling type that breaks camera function and cuts kind of a mechanism.

The utility model solves the problems of the technologies described above with following technical scheme:

Cane planting relative rolling type of the present utility model is cut kind of a mechanism, it mainly consists of by being a pair of roller and four cutting knifes that are installed on the bearing block of arranging up and down, two cutting knifes of symmetrical installation on the radial direction of each roller, two roller ends realize rotating synchronously by two identical gear external toothings, and one of them roller is connected with hydraulic motor.

The structure that described roller is installed cutting knife is: each cutting knife is installed on the roller by the square tool rest of two symmetries, and the square tool rest is bolted on roller, and cutting knife places between two square tool rests and is bolted.

Each cutting knife of the present utility model has the U-shaped mounting groove, is convenient to regulate the radial position that cutting knife is installed at roller.

The utility model is cut stability and the accuracy that cutting has improved in kind of mechanism, possesses simultaneously certain anti-broken camera function.The utility model is cut kind of mechanism can adopt the fluid motor-driven that rotating speed is low, rated power is little, and mechanism is light and handy, and flexibility is strong, and motional inertia is little simultaneously, is quick on the draw, and makes things convenient for the automation control of sugarcane kind diced system.

Embodiment

As depicted in figs. 1 and 2, cane planting relative rolling type of the present utility model is cut kind of mechanism and mainly is made of a pair of roller 4 and four cutting knifes 7, a pair of roller 4 is to arrange up and down and is installed on the bearing block 3, be symmetrically installed with two cutting knifes 7 that become 180 ° on the radial direction of each roller, each cutting knife 7 all is installed on the roller 4 by the square tool rest 5 of two symmetries, square tool rest 5 is bolted on roller 4, and cutting knife 7 places between two square tool rests 5 and is bolted.For ease of installing firmly, also can between cutting knife 7 and square tool rest 5, place pad 6 is installed.

The blade 7 that the utility model adopts can be provided with U-shaped mounting groove, as shown in Figure 3, can adjust the position of blade on the radius of roller direction by U-shaped mounting groove, thereby regulate as required the real work radius of point of a knife.

The utility model when mounted, roller bearing 1 two ends of two rollers 4 put rolling bearing, rolling bearing are installed on the bearing block 3 again; Roller bearing 1 outer end of two rollers 4 is equipped with respectively the gear 2 of identical and external toothing, realizes that by two identical gear external toothings synchronous backwards rotate, and the projecting shaft with the roller bearing of upper roller is connected with the output shaft of hydraulic motor by shaft coupling again; By bolt bearing block 3 is fastened on the mounting seat at last, can realizes the cutting function of sugarcane kind.

Operation principle of the present utility model: hydraulic motor is from the roller bearing one end input power of upper roller, under identical external gear pump effect, drive two rollers as shown in Figure 5 direction do the synchronous backward rotation, blade 7 is done reverse circular motion with roller 4, blade 7 with the roller rotary course in, two blade cutting edges distance about being positioned on two rollers constantly approaches, until cutting edge overlaps, sugarcane is cut off; Two rollers continue rotation, and two blades of having finished cutting function separate gradually with circular motion, and other two blades are along with circular motion, the cutting edge distance is constantly close, and simultaneously as shown in Figure 5 direction conveying of sugarcane is at certain position, cutting edge contacts with sugarcane, and mechanism then enters next time cutting operation.

Two blades of the utility model relative rolling type cutting mechanism are also carried out the clamping cutting simultaneously, relatively disk and linear reciprocation cutting, its roller rotation rate is low, enters cutting vibrating and impacts little, the clamping action that two hobboing cutters attach when cutting off has improved stability and the accuracy of cutting.

The utility model is cut kind of mechanism can realize separately sugarcane kind cutting function, also can be installed on the sugarcane planting machine, assists its realization limit to cut the function of sugarcane kind limit plantation.
