Abstract

A cement mixing truck with a residue removal assisting device is characterized in that the residue removal assisting device is arranged between a mixing drum and a sub-frame of a common cement mixing truck, the residue removal assisting device is composed of bump blocks fixed in the periphery of the mixing drum and a bearer arranged on the sub-frame, and a bump rod and a spring are arranged in the bearer. The bump rod is positioned in the periphery where the bump blocks pass by during the rotation of a drum body when the mixing drum is cleaned, so the mixing drum is controlled to rotate in a discharging direction, the bump rod regularly bumps the drum body under the action of the bump blocks and the spring to make adhesions in the drum shaken and fall, and the adhesions are carried away by flushing water, thereby the device plays a positive role in cleaning assistance; and the bump rod is moved back together with the bearer, and can depart from the bump blocks to recover the normal work state of the cement mixing truck. The cement mixing truck with the residue removal assisting device has the advantages of simple structure, no additional power, good effect and low cost.

Description

A kind of cement stirring conveying vehicle of tape erasure residue servicing unit

Art

The present invention relates to a kind of cement stirring conveying vehicle, especially a kind of cement stirring conveying vehicle with removing residue servicing unit in mixing drum.

Background technology

At present, cement both domestic and external stirs the servicing unit that residue in mixing drum all do not removed by transport vehicle, general all with the residue in water flushing cylinder, because poor effect makes the cement remained in cylinder form bulk through accumulating over a long period, stick in cylinder, it not only reduces the dischargeable capacity of cylindrical shell, and has a strong impact on and load and unload cement work normally.Common way is that operating personnel's hammer or hard object knock mixing drum outer wall, residue in cylinder is split away off, screw feeder (water conservancy diversion) plate in residue seriously bonds the stifled cylinder of even resistance, and when affecting normal handling material, then open the window be located on cylindrical shell interlude outer wall, go to remove residue by manually climbing in cylinder, not only elimination effect is poor as seen, and large to the labour intensity of workman, workman enters in cylinder also very dangerous.Utility application number is 201320257246.8; Application for a patent for invention numbers 201310177912.1, name is called that " cement stirring conveying vehicle of tape erasure residue servicing unit " has invented the device of a kind of leaf spring as flexible member and tapping board, it also can play auxiliary effect of removing residue, is the another kind of technical scheme of the present inventor.

Summary of the invention

The object of this invention is to provide a kind of servicing unit removing residue, when carrying out residue operation in removing cylinder, the power of agitator truck self can be utilized, the residue adhered to is split away off, be more convenient for rinsing with water in cylinder.

The present invention solves the technical scheme that its technical problem takes, on the cement stirring conveying vehicle be made up of automobile chassis, front support bracket assembly, subframe, mixing drum, rear support bracket assembly, loading and unloading assembly, a kind of servicing unit removing residue of design and installation, it is made up of collision block, trip rod, bearing, spring, base, the collision block removing residue servicing unit is fixed on the periphery wall of mixing drum, the bearing of trip rod and spring and floor installation is housed on the subframe under mixing drum.When trucd mixer is in cleaning state, trip rod contacts with collision block, and along with the smooth rotation of mixing drum, trip rod, under the effect of collision block, utilizes spring constantly to be clashed into cylindrical shell regularly by the energy compressing rear release; And when trucd mixer is in transport condition or normal dress discharge operation, moves after the bearing of trip rod is housed, trip rod and collision block are thrown off, do not affect the normal operation of mixing drum.

The invention has the beneficial effects as follows

1, can when trucd mixer be in cleaning state, regularly under cylindrical shell smooth rotation clash into cylindrical shell outward at cylinder, the residue sticked in cylinder is struck and shakes, be convenient to allow the current rinsed take out of outside cylinder, fundamentally change the method for being beaten by manpower, effectively reduce labor intensity.

2, the self power owing to utilizing mixing drum to rotate, structure is simple, and cost is low.

Detailed description of the invention

A kind of cement stirring conveying vehicle of tape erasure residue servicing unit, it is by automobile chassis 1, front support bracket assembly 2, subframe 3, mixing drum 4, rear support bracket assembly 7, feeding, discharge assembly 8 and removing residue servicing unit 6 form, and it is removed residue servicing unit 6 and is made up of collision block 5, trip rod 9, bearing 10, spring 11, base 12.From accompanying drawing 1,2, collision block 5 point two circle of cleaning residue servicing unit is fixed on the interlude outer surface of mixing drum 4 equably, also can according to stirring the varying in size of cylindrical shell, the increase and decrease number of turns or by collision block 5 simultaneously fixed and arranged on the outer surface of forward and backward two conical shells of mixing drum; Diagram often encloses fixed and arranged four collision blocks 5, also according to circumstances rationally can increase and decrease the quantity of collision block 5.Be inserted in bearing 10 by the visible trip rod 9 of accompanying drawing 2, trip rod 9 holddown spring 11 by spring 11 because of by compression and the impulsive force put aside conducts out in bearing 10 chamber, bearing 10 is arranged on the slide block in base 12 groove, base 12 is fixedly mounted on subframe 3, be fitted with the bearing 10 of trip rod 9, spring 11, can move in the groove of base 12 with the slide block in base 12 groove.Fig. 6 removes the in running order structural representation of residue servicing unit, and the trip rod 9 now on bearing 10 is on the circumferential position of collision block 5 fixing on mixing drum 4, and when mixing drum 4 rotates, each collision block 5 circumferentially will contact with trip rod 9 in succession; Fig. 7 removes residue servicing unit disengaged condition structural representation, now moved after the groove of base 12 together with trip rod 9 by the visible bearing 10 of accompanying drawing, be separated from circumferential position mixing drum 4 being fixed collision block 5, when mixing drum 4 rotates, each collision block 5 circumferentially no longer contacts with trip rod 9; Collision block 5 and trip rod 9 progressive contact view shown in Fig. 3,4,5, in conjunction with accompanying drawing 2,3,4,5 as seen when mixing drum 4 counterclockwise rotates, the head end of trip rod 9 along the working face of collision block 5 contacts the cambered surface of collision block 5 by Fig. 3, Fig. 2 arrives collision block 5 cambered surface terminal, the plane of knocking collision block 5 of Fig. 4, the collision block of disengaging completely 5 to Fig. 5, describe trip rod 9 via collision block 5 under the effect of spring 11 to mixing drum 4 knockout process.

A kind of removing residue work of cement stirring conveying vehicle of tape erasure residue servicing unit is carried out in the following manner, first bearing 10 is moved forward together with the groove of trip rod 9 along base 12, make trip rod 9 be in collision block 5 to rotate circumferentially, the duty shown in 6 in accompanying drawing, then handle mixing drum 4 and be shown as counterclockwise (mixing drum blanking rotation direction) smooth rotation by Fig. 2, now along with each collision block 5 sequential order on its periphery of smooth rotation of mixing drum 4 contacts with trip rod 9, trip rod 9 clashes into mixing drum 4 again and again by regular under the effect of spring 11, serve the booster action of the residue abate sticked in mixing drum 4, residue is taken out of by the current rinsed outside mixing drum.After stopping cleaning, only bearing 10 need be moved backward together with the groove of trip rod 9 along base 12, make trip rod 9 leave the circumference of collision block 5 rotation, the disengaged condition shown in 7 in accompanying drawing, cement stirring conveying vehicle has just recovered normal state.
