Description

Vibration plate compactor

The utility model relates to a kind of building ballast consolidating machine, especially a kind of vibratory compactor that soil or making discrete material are carried out closely knit operation that is suitable for.

In prior art, the mechanical type that is used to tamp is various, and more small-sized compacting machine such as ZB type plate concrete vibrator, it is directly vibrative by two eccentric wheels are housed on the motor reel; The vibratory plate compactor that and for example is used for the models such as ZH.HZO of poor cohesive soil compacting, be to drive eccentric type vibrator through belt pulley by motor, carry out work, the vibration force that the said mechanism vibrator produces all acts directly on the tamping plate, damage machine easily when running into rubble or approaching compacting, and all do not have buffer between its motor and vibrator, motor and operator are directly passed in vibration like this, this damages motor easily, influences machine application life.Make the operator influenced by vibration force and very easily tired and uncomfortable.And its speed can not conversion, has also limited its scope of application.

The purpose of this utility model is to have designed a kind of novel rammer compacter in order to overcome above-mentioned the deficiencies in the prior art part, mainly be that the place has set up buffer between vibrator and tamping plate and motor and vibrator etc., and running part is a variable-ratio.So just can eliminate the adverse effect of vibration effectively, prolong the application life of machine.

Task of the present utility model realizes as follows.It comprises tamping plate, supports before fixing two respectively on it and the back is supported, and is fixed with the vibrator casing above the preceding support, is fixed with bearing and bearing gland, multidiameter, eccentric wheel in the casing of vibrator, is fixed with small belt pulley on the spindle nose of multidiameter.Be fixed with motor on the motor base above the back is supported, on the spindle nose of motor big belt pulley be housed, connect multidiameter in the vibrator by the V-belt, the bent plate below manipulating handgrip and the motor base is fixed; Be connected with the buffer spring group between bent plate that is connected with motor base and vibrator.Two belt pulleys that vary in size, its axis hole is identical, and the two can exchange installation, can reach the purpose of vibrator throw-over.

Described buffer spring group is by two angle steel that are fixed on vibrator casing back middle part and bottom and be fixed on bent plate top and middle part two angle steel, spring and bolts are formed in the other direction, in the middle of the angle steel two springs are housed in the other direction at per two, with bolt that each group spring and angle steel polyphone is fixing.

Support by bolt, spring before described and go up lower spring cup and forms, the lower spring cup one side all has a boss it on, and the boss external diameter matches with spring inside diameter, and boss is interior to be shrinkage pool, and there is circular hole at its center, will go up lower spring cup and the spring formation of contacting with bolt.

The shrinkage pool at described upper spring seat center, height and bolt head height sum that its height should can compress greater than spring.

Described back is supported and is comprised the threaded multidiameter of a plurality of rubber rings and rubber ring support, spring and two, and there is gland rubber ring support bottom, and the upper end of rubber ring support is welded on the bent plate bottom.

Described manipulating handgrip comprises handgrip, rubber ring and gland and bolt, and handgrip is to make " U " type handle by pipe, and its termination portion is welded with a short sleeve, and a plurality of rubber rings are housed in the sleeve, and there is gland its outside, by bolt handgrip is fixed on the side plate of bent plate.Can reduce the adverse effect of vibration like this to the operator.

The utility model has following advantage compared with the prior art: because of between the motor of this machine and vibrator and between both and tamping plate and operator the junction is provided with buffer, so just can reduce the adverse effect of vibration to machine and operator, make its running steadily, thus the application life of having improved machine.Belt pulleys owing to two different sizes can exchange again, so vibrator can change speed, to adapt to different needs.And compact integral structure is reasonable, makes easily, and is in light weight, cost is low, and applied range can be on small-sized road surface, narrow groove, pipe trench, casting carry out compacting operation with ditch, toft ground, place etc.Be not only applicable to bearing courses such as silt, poor cohesive soil, lime-ash, can be used for the compacting operation of rigid layer of concrete etc. yet.
