Abstract

The utility model discloses an eccentric shaft vibration subsoiler which consists of a frame, a hanging bracket, a tiller wheel and a supporting wheel. Key points are as follows: a rear output shaft of a tractor is connected with a spline main shaft of a gear box by the hanging bracket and a universal joint, and a pair of bevel gears in the gear box are connected with driven spline shafts with chain wheels at two ends while the chain wheels at two sides are respectively connected with two eccentric shafts at two ends by double chains; two ends of the driven spline shafts are respectively provided with a connecting rod I and the eccentric shafts at two ends are respectively provided with a connecting rod II; the other ends of the connecting rod I and the connecting rod II are movably connected with a shovel board connecting frame by a connecting pin and a universal ball head respectively, and scarifying shovels are fixed on the scarifying shovel board. The gear box of the subsoiler is an integral structure and four scarifying shovels are adopted for operation while the distance between the scarifying shovels is 450mm. The subsoiler is in bilateral symmetry with good balance, and is matched with the tractor with 50 to 85 horsepower for operation. The subsoiler can subsoil 10 to 20 acres of lands per hour, and can be used as a new-generation subsoiling machine.

Description

The eccentric shaft Viberation deep coosener

Affiliated technical field

The utility model relates to agricultural machinery technological field, specifically a kind of tillage machinery of chiselling earth.

Background technology

Actual situation is also deposited, and interval subsoiling is a kind of advanced methods of cultivation that form in recent years.The main feature of this method is to make the hardening layer of soil to become flexible, and changes the long-term rotary tillage of soil and causes the problem of soil compaction, impels and pricks crop root under, and the increase crop is to the absorption of soil nutrient.Simultaneously, also improve the performance of retaining and conserveing soil moisture of soil, promoted growing and increasing output of crop.But existing subsoiler often tractive resistance is bigger, and the effect of loosening the soil is poor; Most gearbox is split type, processed complex, and during installation fee and easily leakage of oil, mechanical property is also stable inadequately; Simultaneously, the subsoiler of selling on the market mostly is three break shovel structures, and distance is greater than 500mm between the break shovel, because spacing is bigger, so the facility operation is stable inadequately, and the saturating soil compaction layer of pine fully, the effect of loosening the soil is ideal not really.

Summary of the invention

In order to solve the deficiency that the existing machinery that loosens the soil structurally exists, it is integral type that the utility model provides a kind of gearbox, and the distance between the break shovel is reasonable, the dark high eccentric shaft Viberation deep coosener of spongiosa amount.

The technical scheme that its technical problem that solves the utility model adopts is: this eccentric shaft Viberation deep coosener, comprise frame, suspension holdfast, cut native wheel, support wheel and supporting leg, mainly be that the tractor rear output shaft is linked by suspension holdfast and universal joint and gearbox spline spindle, a pair of bevel gear in the gearbox connects with the driven spline shaft of two ends band chain wheel, and the sprocket wheel of both sides is connected with the eccentric shaft at two ends by double-stranded bar respectively; Connecting rod I is equipped with at the two ends of driven spline shaft respectively, and the eccentric shaft at two ends is equipped with connecting rod II respectively; The other end of connecting rod I and connecting rod II flexibly connects by an end that is connected bearing pin and universal ball end and shovel board link respectively, the middle part of shovel board link flexibly connects by supporting bearing pin and frame, the other end of shovel board link is connected with the shovel board of loosening the soil, fixing break shovel on the shovel board of loosening the soil; Said break shovel is shovel hoe formula break shovel, and distance is 400～500mm between two break shovels.

The utility model major advantage compared with prior art:

The one, reasonable structure.Because gearbox is integral structure, thus the processing of facility, install all very convenient, steady quality, not easy oil leakage.Adopt four break shovels to loosen the soil simultaneously, the facility left-right symmetry, balance is good, and operation is stable, and has prolonged the service life of facility.

The 2nd, the quality of dark pine is good, the operating efficiency height.Because distance is 450mm between the break shovel, has increased break shovel simultaneously, therefore can the soil compaction layer of 25-40cm is loose fully saturating, the quality of loosening the soil complies with the national standard requirements fully.With the tractor operation of 50-85 horsepower, operating efficiency reaches per hour chiselling ground 10-20 mu.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in detail:

Shown in Fig. 1-5, this eccentric shaft Viberation deep coosener, comprise frame 5, suspension holdfast 4, cut soil wheel 1, support wheel 9 and supporting leg 15, mainly be that the tractor rear output shaft is linked by suspension holdfast 4 and universal joint and gearbox spline spindle 2, a pair of bevel gear 20 in the gearbox 3 connects with the driven spline shaft 12 of two ends band chain wheel 13, and the sprocket wheel 13 of both sides is connected with the eccentric shaft 14 at two ends by double-stranded bar respectively; Two connecting rod I11 are equipped with at the two ends of driven spline shaft 12 respectively, and the eccentric shaft 14 at two ends is equipped with two connecting rod II10 respectively; The other end of connecting rod I11 and connecting rod II10 flexibly connects with shovel board link 6 by being connected bearing pin 18 and universal ball end 16 respectively, the middle part of shovel board link 6 flexibly connects with frame 5 by supporting bearing pin 17, the other end of shovel board link 6 is connected with the shovel board 7 of loosening the soil with bolt 19, fixing break shovel 8 respectively on the shovel board of loosening the soil 7; Said break shovel 8 is shovel hoe formula break shovel, and distance is 450mm between two break shovels 8, working width 1800mm.

The course of work of the present utility model is:

After interconnecting by universal joint and gearbox spline spindle 12 by the tractor rear output shaft, drive gearbox driven spline shaft 12 by a pair of bevel gear in the gearbox 3 and rotate, by two pairs of internal spline sprocket wheels 13 and two groups of double-stranded bars driven spline shaft 12 and two ends eccentric shaft 14 are linked together again.Because connecting rod I11 is equipped with at the two ends of driven spline shaft 12 respectively, eccentric spline housing is housed in the connecting rod I11, and connecting rod II10 is housed respectively on two eccentric shafts 14, so, when driven spline shaft 12 rotates, just drive four connecting rods and carry out eccentric rotary.Four break shovels 8 are separately fixed on four shovel boards 7 of loosening the soil, four loosen the soil shovel board 7 respectively by four connecting rods and shovel board link 6 be connected bearing pin 18 and universal ball end 16 interconnects, when four connecting rods are made eccentric rotary, drivening rod and shovel board linkage frame 6 be that fulcrum is swung to support bearing pin 17, and the while also drives break shovel about in the of 8, swing front and back.When tractor advanced, the soil that will harden that swings back and forth by break shovel 8 became flexible.
