Abstract

The utility model relates to a novel copying transmission mechanism of a pasture harvester and belongs to the field of pasture harvesters of the animal husbandry. The novel copying transmission mechanism of the pasture harvester is mainly composed of a fixed cutter, a movable cutter, a movable cutter installation plate, a copying component, a transmission component and a base. A power input shaft is supported by two needle bearings and is installed in a power shaft protective sleeve so that the copying component can be formed. The transmission component is composed of an eccentric block, a U-shaped rocker, a T-shaped supporting rod, a rocker and a front shifting rod and is arranged in front of the copying component. The cutting parts such as the movable cutter and the fixed cutter are arranged in front of the transmission component. The copying component achieves copying of complicated earth surface conditions, so that pasture harvesting operation is better conducted, the adaptability of the pasture harvester is improved, and the operation quality is improved. The displacement generated by power in the process of transmission in the vertical direction can be eliminated by the transmission component, as a result, vibration and impact are reduced, the service life of the parts is prolonged, and the application value of the pasture harvester is effectively improved.

Description

The novel profiling transmission mechanism of grass harvester

Technical field

The utility model relates to livestock breeding grass making machinery field, relates in particular to the novel profiling transmission mechanism of grass harvester.

Background technology

Along with the fast development of herding industry, pasture growing area expands year by year, and owing to not being applicable to facility, the herbage harvesting in mountain and hill area is a stubborn problem always.The general problem existing of small-sized grass harvester mainly contains two aspects: the one, cannot be in plot, hills, hillside and the larger good operation in plot of surface relief, cause a lot of herbage to leak to cut or toothing too high, operation quality is poor; The 2nd, the cutter power of most grass harvesters is all to be transmitted scriptures and directly driven cutter to move reciprocatingly by eccentric block by engine direct, and this just causes the vibration of eccentric drive mechanism larger with impact, and part easily damages, and affects operating efficiency.

Summary of the invention

The problem that the utility model mainly solves is cannot profiling when the harvesting and transmission mechanism functional reliability is low and the problem of rapid wear for current small-sized grass harvester, provide a kind of adaptability better, can effectively reduce component wear, improve the novel profiling transmission mechanism of the grass harvester of operating efficiency.

The problem proposing for solving the utility model, adopts following technical scheme:

The novel profiling transmission mechanism of grass harvester, mainly comprises stationary knife, moving knife, moving knife installing plate, front movable board, front driving lever, rocking bar, T-shaped pole, U-shaped rocking bar, eccentric block, line shaft sheath, power input shaft, needle bearing and base.Line shaft sheath is welded on base, power input shaft front end connects with eccentric block upper end, T-shaped pole lower end is arranged in the bearing on base 13, U-shaped rocking bar rear end connects with the bearing that eccentric block lower end arranges, front end connects with T-shaped pole, rocking bar rear end and the welding of type pole, front driving lever connects with rocking bar front end and is arranged in front movable board, and front movable board connects with moving knife installing plate, moving knife is arranged on moving knife installing plate, and stationary knife is fixed on base front end.

Several needle bearings are arranged on power input shaft, are arranged in line shaft sheath.The transmission mechanism being comprised of power input shaft, eccentric block, U-shaped rocking bar, T-shaped pole, rocking bar and front driving lever can be eliminated the displacement of the vertical direction that in power transmission process, part produces.

The utility model mainly utilizes needle bearing inner ring and outer ring with respect to relatively rotating in power input shaft and line shaft protective sleeve, impel cutting part to do and rotate by a small margin better to adapt to surface condition, reach the effect to earth's surface profiling, improve herbage harvesting effect, guarantee operation quality; Utilize U-shaped rocking bar the relatively rotating of T-shaped pole and eccentric block coupled position, eliminate the displacement of the parts vertical direction causing in power transmission process, reduce parts vibration, improve complete machine operating efficiency.

Accompanying drawing explanation

Fig. 1 is that the utility model axle measures intention.

Fig. 2 is the utility model end view.

In figure: 1-stationary knife, 2-moving knife, 3-moving knife installing plate, 4-front movable board, 5-front driving lever 6-rocking bar 7-T-shaped pole 8-U-shaped rocking bar 9-eccentric block, 10-power protective sleeve, 11-power input shaft, 12-needle bearing, 13-base.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done further and described in detail: as shown in Figure 1 and Figure 2, the novel profiling transmission mechanism of grass harvester, mainly comprises stationary knife 1, moving knife 2, moving knife installing plate 3, front movable board 4, front driving lever 5, rocking bar 6, T-shaped pole 7, U-shaped rocking bar 8, eccentric block 9, line shaft sheath 10, power input shaft 11, needle bearing 12 and base 13.Line shaft sheath 10 is welded on base 13, power input shaft 11 front ends and eccentric block 9 upper ends are fixedly connected, T-shaped pole 7 lower ends are arranged in the bearing of base 13 middle parts settings, U-shaped rocking bar 8 rear ends are arranged on the bearing of eccentric block 9 lower ends, front end sleeve is contained on the transverse axis of T-shaped pole 7, the transverse axis welding of rocking bar 6 rear ends and T-shaped pole 7, front driving lever 5 is arranged in the arc notch of front movable board 4 through rocking bar 6 front ends, front movable board 4 is bolted and connects with moving knife installing plate 3, moving knife 2 rivetings are contained on moving knife installing plate 3, and stationary knife 1 is fixed on base 13 front ends.

During work, power imports power input shaft 11 into, power input shaft 11 starts to rotate, the inner ring of needle bearing 12 with power input shaft 11 in the interior rotation of line shaft sheath 10, drive eccentric block 9 to rotate simultaneously, U-shaped rocking bar 8 is under the drive of eccentric block, T-shaped pole 7 vertical pivots of take are done gyration as the center of circle, T-shaped pole 7 take vertical pivot does gyration as axle center, because rocking bar 6 is welded on T-shaped pole 7, rocking bar 6 be take the vertical pivot of T-shaped pole 7 and is done oscillating motion as the center of circle, front driving lever 5 is synchronized with the movement with rocking bar 6, and promote front movable board 4 and move reciprocatingly, thereby drive the moving knife 2 of installing on moving knife installing plate 3 to move reciprocatingly, moving knife 2 has coordinated cutting operation with the stationary knife 1 that base 13 front ends are installed.When running into the situation of earth's surface injustice, power input shaft 11 drives the inner ring of needle bearings 12 and with respect to the outer ring rotating of needle bearing 12, drive disk assembly and cutting part is rotated by a small margin, reaches the object parallel with earth's surface.
