Description

A kind of novel Cultivating seed-harrow

Technical field

Include crop straw crusher the utility model relates to agricultural machinery, stubble cleaning rotary tiller, big plough, disc harrow, loosen the soil Rotary cultivator, combined seed and fertilizer drill, in particular to a kind of novel Cultivating seed-harrow.

Background technique

Plantation for ridge culture crops usually will first carry out stubble-cleaning operation, by the loss stalk of the crops of the previous year, Root stubble is broken, is then ploughed, is raked the soil level, ridging operation, could be sowed later on ridge.

Currently, can be completed by stubble-cleaning ridger for the stubble-cleaning in large stretch of farmland, ridging operation, this stubble-cleaning ridger It is usually made of, is mounted on large tractor stubble-cleaning knife and furrower, it can be simultaneously to a plurality of ridge by tractor-drawn driving Carry out stubble-cleaning, ridging operation.Fore stubble-cleaning knife is wherein installed and completes stubble-cleaning operation, and rear-mounted furrower is completed It ploughs ridging operation.This universal volume of stubble-cleaning ridger is larger, is not suitable for mountain area, hilly country or individual fritter The stubble-cleaning in farmland, ridging operation.Therefore mountain area, the stubble-cleaning of hilly country or individual haggard, ridging make sparetime university at present It is mostly to be respectively completed using the small-sized stubble-ploughing machine and small ridging machine with simple function.Due to small-sized stubble-ploughing machine and small ridging Machine is separately mounted on individual event on baby tractor (such as hand tractor) and carries out stubble-cleaning operation and ridging operation, both time-consuming to take Power, and the consumption of the energy is increased, no matter consider from economic benefit or from working efficiency, it is undesirable, it would be highly desirable to be changed Into.

Various something lost stalks are planted by standardized work requirement at present and retain the more and higher milpa of crop root residue, then are needed Above-mentioned corresponding mechanical substep carries out.Obviously, it not only needs more mechanical type, fuel oil consumption height, duty cycle long, but also needs Personnel are more, plant maintenance heavy workload, cost are also very high.

, separately there are notification number CN103460839 patent, utility model title in the shortcomings that in order to improve above-mentioned existing agricultural machinery For stubble cleaning and ridging tillage machine comprising: rack, clutch, gearbox, rotary shaft, spiral shape knife rest, blade, furrow carding, Divide native control panel, adjust bolt.Wherein the front end of rack, which is equipped with, is set to rack with tractor interconnecting piece, clutch and gearbox On, the input shaft of gearbox passes through the power output axis connection of clutch and tractor.Rotary shaft be set to the middle part of rack with The output axis connection of gearbox.On the rotary shaft side by side be equipped at least two spiral shape knife rests being staggered, in spiral shape Along its outer side edges along equipped with multiple blades on knife rest.Furrow carding is set to the rear end of rack, and tip is towards rack Middle part is simultaneously located between two spiral shape knife rests；Point native control panel is equipped in two sides of furrow carding and adjusts bolt.Wherein The length that the blade of spiral shape knife rest bottom extends downwardly is greater than the length that the pointed end of furrow carding is stretched out.However this It plants structure but causes other following defects in use:

1, the patent be on the rotary shaft side by side be equipped at least two spiral shape knife rest groups being staggered, this combination Mode is fixed, and not flexible and processing and maintenance difficulties are big.

2, the mounting plate of the patent is reversed by one piece of single layer semicircular plate, and bearing capacity is poor, be easy to cause knife rest Deformation.

3, the patent is along its outer side edges on spiral shape knife rest along multiple blades are equipped with, since the blade is to be attached to outside Side edge be easy to cause blade deformation and fracture so blade bearing capacity is poor, is easy to be broken in bolt bearing.

4, since the blade of the patent is board foot shape, cause stock-removing efficiency low, band weeds easy to hang and foreign matter on blade.

5, since the cutter frame structure of the patent is complicated, combination is single, make its production technology complexity, difficult processing, installation Inconvenient with disassembly, maintenance and maintenance are also inconvenient, to cause processing, maintenance cost high.

6, since the land wheel of the patent is to be fixedly connected, frictional force size is unstable, and output power is unstable It is fixed, directly affect the precision of sowing and fertilising.

7, since the jolt-squeeze device of the patent is fixed on ridge platform, function of covering soil is undesirable.

8, it since the structure two sides of the patent do not have seeder lifting apparatus, be easy to cause in machine run and is newly formed Ridge platform is destroyed.

In view of above-mentioned existing many disadvantages, the designer proposes operation once can realize that above-mentioned operation is appointed comprehensively Business requires design scheme, makes it with more practicability.
