Abstract
The utility model discloses a farming machine tool. The farming machine tool comprises a cutter disk and blades fixed to the cutter disk, wherein the blades are in the shape of arcs, the blades comprise the upper-layer blade and the lower-layer blade, the cutting edge of the upper-layer blade and the cutting edge of the lower-layer blade are respectively provided with inclined teeth which are arranged at equal intervals, a damping spring is arranged between each pair of inclined teeth overlapped in the upper-layer blade and the lower-layer blade, and a small opening is formed in the cutting edge of each inclined tooth. According to the farming machine tool, the two layers of blades are adopted, one damping spring structure is arranged between each pair of opening inclined teeth, and the farming machine tool is applicable to ploughing various kinds of soil and has the advantages of being wide in durability, practicability and function. The farming machine tool solves the problems that an existing farming machine is low in operation efficiency when used in soil with roots, stems and weeds or large-viscidity soil, and the farming effect expected by people can be achieved.
Description
Technical field
The utility model relates to a kind of agricultural ploughing machine, is specifically related to a kind of agricultural ploughing machine cutter.
Background technology
Along with the development of the mechanization of modern agriculture, mini-size tillage machine, rotovator substitute manually carry out agriculture arable land, ridging, ditch, loosen the soil, the relevant operation such as seed covering and the forestry reclamation of wasteland.Existing loom all adopts single blade, realizes agro-farming operation, and this loom is simple in structure, comparatively convenient when use, in actual production operation, tends to run into: one, affect production efficiency because soil property is special, two, do not reach the agro-farming effect of expection.
For example: in soil, have large compared with the viscosity of the rhizome of toughness, weeds or soil.
Summary of the invention
The purpose of this utility model is a kind of agricultural ploughing machine cutter providing in order to solve the problems of the technologies described above, and realizes the high efficiency of agro-farming operation.
The utility model is that the technical scheme addressing the above problem is:
Include cutterhead and be fixed on the blade on cutterhead, blade is curved, described blade comprises upper strata blade and blade, is respectively equipped with the helical teeth of equidistant arrangement on the blade of described upper and lower layer blade, the middle damping spring that is provided with of every a pair of helical teeth that upper strata blade and blade are overlapping.
As preferably, damping spring is cylindrical spring.
As preferably, the cross sectional shape of the osculum on the cutting edge of helical teeth is trapezoidal.
Useful technique effect of the present utility model:
Compared with prior art, the blade that a kind of agricultural ploughing machine cutter of the utility model adopts is double-layer blades, is equidistantly provided with opening helical teeth on the blade of double-layer blades.Adopt double blade more easily to open up wasteland various cultivated soils, adopt opening helical teeth, can excise the root with toughness, stem and weeds in soil, improve operating efficiency, realize the agro-farming effect of expection.
Compared with prior art, a kind of agricultural ploughing machine cutter of the utility model overlapping every a pair of helical teeth centre on upper and lower layer blade is provided with damping spring, and damping spring can increase temporarily or reduce under actual production situation.Damping spring except playing shock-absorbing function in the time working, can produce active force and reaction force in effective generation amplification, in the motion of upper and lower layer gap blade, can remove blade clay, effectively save machine power past second ploughing, cultivate loss, save the service life of resource and the prolongation machinery equipment of manpower, material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of blade;
Fig. 3 is the mounting structure schematic diagram of helical teeth and damping spring;
Fig. 4 is that damping spring is cylindrical spring;
Fig. 5 is that damping spring is volute spring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to further detailed elaboration.
Consult Fig. 1 to Fig. 5
A kind of agricultural ploughing machine cutter, include cutterhead 1 and blade 3, described blade 3 is fixed on the circumferencial direction of cutterhead 1 uniformly by screw 2, blade 3 comprises upper strata blade and blade, on the blade of upper and lower layer blade, be respectively equipped with the helical teeth 4 of equidistant arrangement, overlapping every a pair of helical teeth 4 centres of upper strata blade and blade are provided with damping spring 5, have trapezoidal mouthful on the cutting edge of helical teeth 4.
Damping spring 5 plays vibration-damping function while can the helical teeth 4 on agricultural ploughing machine cutter cutting soil, and resistance is little, and operating efficiency is fast.Damping spring 5 can also effectively produce active force and the reaction force in amplification in addition, and opening helical teeth 4, in the time of upper and lower layer gap blade motion, can be removed the clay on blade 3, in excision soil, is with the functions such as toughness rhizome, root knot.
The past second ploughing of so effective saving machine power, cultivate loss, save the resource of manpower, material and extend service life etc. of machinery equipment.
Can be according to the working width of machine (width) when use, select the diameter of institute's frame cutterhead, cutterhead conventionally should be selected by ploughing, cultivate the key element such as soil depth and machine transmission power, simultaneously in soil property, plough that to cultivate vegetation experience be also one of key element of considering.
Claims (3)
1. an agricultural ploughing machine cutter, include cutterhead and be fixed on the blade on cutterhead, described blade is curved, it is characterized in that: described blade comprises upper strata blade and blade, on the blade of described upper and lower layer blade, be respectively equipped with the helical teeth of equidistant arrangement, the middle damping spring that is provided with of every a pair of helical teeth that upper strata blade and blade are overlapping.
2. a kind of agricultural ploughing machine cutter according to claim 1, described damping spring is cylindrical spring or volute spring.
3. a kind of agricultural ploughing machine cutter according to claim 1, has osculum on the cutting edge of described helical teeth.
