Abstract
The utility model relates to a small amplitude vibratory excavator. The small amplitude vibratory excavator comprises a bucket, a vibratory rod hose, a fixed support, a bearing and a vibratory rod. The vibratory rod hose is connected with the vibratory rod. The end of the vibratory rod hose close to the vibratory rod is in a right angle state. The fixed support is fixed on the bucket. The bearing is installed on the fixed support. A bearing outer ring is in interference fit with the fixed support. A bearing inner ring is in interference fit with the vibratory rod. The vibratory rod hose is connected with a vibratory system switch. The vibratory rod hose, the vibratory rod and the vibratory system switch form a vibratory system. The small amplitude vibratory excavator provided by the utility model is simple in structure, long in service life and wide in application range, and under the condition that original assembly is not changed, the bucket resistance can be reduced effectively, the energy consumption can be reduced, and the delay phenomenon is avoided when the small amplitude vibratory excavator is resisted in the process of cutting soil by the bucket, and the sensitivity is high.
Description
Technical field
The utility model relates to a kind of vibration excavator, especially relates to a kind of little amplitude formula vibration excavator.
Background technology
Hydraulic crawler excavator in the course of the work because the speed of scraper bowl cutting soil is different, the version of cutting force is also inequality in the cutting soil course.For the cutting of the slow static state of cutting speed, when cutter with after soil contacts, owing to soil has certain intensity; When cutting force does not reach the strength limit of soil; Soil produces distortion under the effect of cutting force, simultaneously, and along with cutting force raises gradually; Reach the strength limit of soil when cutting force after, soil begins to be destroyed, and at this moment, cutting force no longer increases.After whole soil block was destroyed, cutting force descended rapidly, and the scraper bowl resistance is big in the whole process, and energy consumption is high.
For existing little amplitude formula vibration excavator, once used a kind of electric-hydraulic proportion to control the bucket cylinder system on it, bucket cylinder is moved reciprocatingly and frequently switching-over under the control of handle, produce vibration, realize the cutwork of scraper bowl.But because the pressure of bucket cylinder is lower, when scraper bowl receives resistance in working angles, tend to the reflection phenomenon occur postponing, reaction sensitivity is poor, inefficiency.
The utility model content
The technical problem that the utility model will solve is, overcomes the deficiency of prior art, provides that a kind of resistance is little, energy consumption is low, sensitive little amplitude formula vibration excavator, use in the excavator course of work, can effectively reduce the scraper bowl resistance.
The technical scheme that its technical problem that solves the utility model adopts is:
Little amplitude formula vibration excavator comprises scraper bowl, goes back involving vibrations rod flexible pipe, fixed bearing, bearing and vibrating head; Vibrating bar hose is connected with vibrating head; Vibrating bar hose is near the rectangular state of an end of vibrating head, and fixed bearing is fixed on the scraper bowl, and bearing is installed on the fixed bearing; Bearing outer ring and fixed bearing are interference fit, and bearing inner race and vibrating head also are interference fit; Vibrating bar hose is connected with the vibrational system switch, and vibrating bar hose, vibrating head and vibrational system switch constitute vibrational system.
Further, said scraper bowl back fixation has reinforcing rib, preferred two of quantity.
The little amplitude formula vibration excavator of the utility model, simple in structure, long service life, applied widely; Under the immovable situation of original assembling, can effectively reduce the scraper bowl resistance, cut down the consumption of energy; When in scraper bowl cutting soil course, receiving resistance, delay phenomenon can not appear yet, and highly sensitive.
Description of drawings
Fig. 1 is the utility model scraper bowl structural representation;
Fig. 2 is the utility model fixed bearing structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
With reference to Fig. 1,2, present embodiment comprises scraper bowl, vibrating bar hose 2, fixed bearing 3, bearing 4, vibrating head 5, and vibrating bar hose 2 is connected with vibrating head 5, and vibrating bar hose 2 is near the rectangular state of an end of vibrating head 5, so that rotate; Fixed bearing 3 is through being bolted on the scraper bowl; Bearing 4 is installed on the fixed bearing 3, and bearing 4 outer rings and fixed bearing 3 are interference fit, and bearing 4 inner rings and vibrating head 5 are interference fit; Vibrating head 5 is followed scraper bowl and is rotated.Said scraper bowl back fixation has two reinforcing ribs 1, and vibrating bar hose 2 is connected with vibrational system switch (not shown), and vibrating bar hose 2, vibrating head 5 and vibrational system switch constitute vibrational system.
The little amplitude formula of the utility model is vibrated excavator in the course of the work, and when operating personnel opened the vibrational system switch, vibrating head 5 vibrated; Drive the scraper bowl vibration, in mining process, the vibration of scraper bowl produces soil block to be impacted thereupon; The fragility soil block is cracked or fragmentation; Thereby help reducing the scraper bowl resistance, cut down the consumption of energy, improve the scraper bowl life-span.In the course of work, vibrating head 5 will vibrate always, can not stop because resistance is excessive, thereby help promoting sensitivity.
Claims (3)
1. little amplitude formula vibration excavator comprises scraper bowl, it is characterized in that; Also involving vibrations rod flexible pipe, fixed bearing, bearing and vibrating head, vibrating bar hose is connected with vibrating head, and vibrating bar hose is near the rectangular state of an end of vibrating head; Fixed bearing is fixed on the scraper bowl; Bearing is installed on the fixed bearing, and bearing outer ring and fixed bearing are interference fit, and bearing inner race and vibrating head also are interference fit; Vibrating bar hose is connected with the vibrational system switch, and vibrating bar hose, vibrating head and vibrational system switch constitute vibrational system.
2. little amplitude formula vibration excavator according to claim 1 is characterized in that said scraper bowl back fixation has reinforcing rib.
3. little amplitude formula vibration excavator according to claim 2 is characterized in that the reinforcing rib quantity at scraper bowl back is two.
