Abstract

The utility model relates to a vertical double-shaft rotary ditcher. The shaft of a roller in the gearbox of a tractor is directly sleeved with different lengths of a front shaft and a back shaft, wherein the front shaft is connected with a long knife bar which is arranged with a right-handed blade, the back shaft is connected with a short knife bar which is arranged with a left-handed blade. The blades arranged on the knife bars are used to do trench digging operations of soil rototiller and soil throw in order to finely divide soil, and simultaneously the utility model has wider adaptation for the moisture percentage range of soil and strong adaptability for all kinds of soil, thereby satisfying with the trench digging requests provided by farming measures. The utility model has the advantages of compact structure, and balancing force couple produced by rototilling soil, thereby largely prolonging life time of the machine. The straight going property of a tractor in the fields is more ideal. The utility model can also be used to the dibbling operations of fruit tree fields, and is applicable to uses of a great lot of farmers.

Description

The dual spindle vertical rotary ditcher

(1) technical field

The utility model relates to a kind of dual spindle vertical rotary ditcher, belongs to the farmland operation facility.

(2) background technology

At present, existing similar vertical ditching machine is a single shaft, be that rotating power source turns to the drive single shaft through a pair of bevel gear, the knife bar and the blade (3-5) that are socketed on the single shaft are cut soil, throw native ditching operation, because cutting native blade is subjected to from the unidirectional cutting resistance of soil, especially when soil moisture content when higher or comparatively sticking heavy, the couple unbalance that produces, cause facility to produce side force, cause the unidirectional impact shock of facility, mechanical breakdown happens occasionally, and structural strength is had relatively high expectations, tractor is straightforward relatively poor in walking of field, and the soil block of dishing out is relatively large, the soil direction of dishing out is single.The farmland trench digging of little spring sown crop such as broad bean, wheat, rape etc. is a crucial agronomic measures, the draining and the control water that help the land for growing field crops, guarantee the full stand in seedling stage, after even, the in small, broken bits crop surface that covers both sides of ditch soil, water conservation be can play, fertile, heat preservation effect protected, being the plantation level that improves late autumn, realizing the important step of standardized planting, also is the requirement of agronomic technique to ditching operation.

(3) summary of the invention

The purpose of this utility model provides a kind of dual spindle vertical rotary ditcher, it is straightforward effectively to solve walking of tractor, the service life that machine vibration is little, prolonged tractor, it is thinner that soil is cut in throwing, and the tractor load alleviates, and the effect of ditch type and throwing soil is all above existing similar type, simple and compact for structure, to soil moisture content range accommodation broad, stronger to various types of soil properties adaptations, satisfied the requirement of agronomic measures preferably to ditching operation.

The purpose of this utility model is achieved in that this dual spindle vertical rotary ditcher, in the transmission case of ditching machine, has power shaft by output shaft of bevel gear socket, output shaft is connected with the knife bar that has blade, in the transmission case of ditching machine, increase by a cover cutter shaft, with former cutter shaft pair roller, form the double-pole axle, the knife bar of diaxon socket is different in size, look by the tractor direction of advance, before diaxon is pressed, the rear is to arrangement, the short sword bar of front axle socket is preceding, the rimmer knife bar of rear axle socket after, the short sword bar is connected with the left-handed blade of two symmetries, and the rimmer knife bar is connected with the dextrorotation blade of two symmetries, and two knife bars are socketed in respectively on diaxon, diaxon is parallel, use gears engaged therebetween, four are staggered the blade and the two between centers quarterings.

This dual spindle vertical rotary ditcher, there is dashboard at transmission case both sides and rear portion, and there is gauge wheel the frame both sides that it is connected with tractor.

The utility model is because the weak point of the twin shaft socket of dual spindle vertical rotary ditcher, rimmer knife bar and blade are in carrying out the moving process of high speed rotating and level, the blade of short sword bar is cut earlier and is thrown 1/2nd dark soil, the blade of rimmer knife bar is cut the soil of throwing 1/2nd remaining ditch depths again, throwing is cut in short sword bar and the rotation of blade level inhour, rimmer knife bar and blade are that level turns clockwise and cuts throwing, like this, the left and right sides of the ditch soil of all dishing out, in cutting the throwing process, because on being, the segmentation of hyposulculus soil is taken out, make soil more in small, broken bits, solved the couple unbalance problem that soil resistance brings of cutting effectively, machine vibration reduces, and the tractor load alleviates, prolonged the service life of complete machine, made the soil energy uniformly dispersing of dishing out on the surface of ditch both sides because of forward and reverse high speed rotating simultaneously, so to soil moisture content range accommodation broad, stronger to various types of soil property adaptability, walking of tractor straightforwardly also can effectively be solved, and satisfied the requirement of agronomic measures to ditching operation preferably.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the transmission principle figure of transmission case of the present utility model.

(5) embodiment

Among Fig. 1 and Fig. 2, four-wheel tractor 1 is the mating power of dual spindle vertical rotary ditcher, 3 hanging devices 9 with routine articulate with the dual spindle vertical ditching machine, a pair of bevel gear 10 is set in transmission case 6,12 and a pair of

helical gear

14,17, the power take-off of tractor links to each other with driving shaft 11 by universal joint, the driving bevel gear 10 of driving shaft 11 sockets makes front axle 13 rotations with driven bevel pinion 12 engagements, front axle 13 is socketed with helical gear 14 and short sword bar shaft coupling 15 simultaneously, short sword bar shaft coupling 15 links with short sword bar 4, short sword bar 4 bottoms are equipped with two left-handed blades 2, active oblique gear 14 meshes with driven helical gear 17 simultaneously, drive rear axle 16 rotations, rear axle 16 is socketed with rimmer knife bar shaft coupling 18, rimmer knife bar shaft coupling 18 links with rimmer knife bar 5, rimmer knife bar 5 bottoms are equipped with two left-handed blades 3, there is gauge wheel 8 the frame both sides that transmission case 6 is connected with tractor 1, gauge wheel 8 is regulated the restriction trench digging degree of depth by handle, transmission case 6 both sides and rear portion are connected with dashboard 7, and controlled is thrown soil distance (adjustable distance) and security protection.

This machine is changed blade shapes, the ditching operation that can carry out different ditch shapes, with the single shaft operation with also can carrying out fruit tree dig operation such as cave.
