Abstract
The utility model relates to a leakage prevention device for a concrete mixing and transporting vehicle, which comprises a rear rack, a mixing tank, a discharge hopper, a hydraulic power unit, a bidirectional hydraulic oil cylinder and a retaining plate. The retaining plate is arranged at the position of a tank opening of the mixing tank and is connected with the discharge hopper by a rotating shaft; the bidirectional hydraulic oil cylinder is horizontally arranged on the rear rack by an oil cylinder connecting seat; a piston rod of the bidirectional hydraulic oil cylinder is connected with a swing rod mechanism arranged on the retaining plate by a hinge pin; and the hydraulic power unit is arranged in the rear rack and is connected with the bidirectional hydraulic oil cylinder by a hydraulic oil pipe. According to the utility model, the retaining plate is arranged at the tank opening and the retaining plate is driven by the bidirectional hydraulic oil cylinder to be opened and closed so as to take the effects of sealing part of the region of the tank opening of the mixing tank, increasing the effective volume of a tank body of the stirring vehicle and avoiding the leakage condition generated due to the insufficient effective volume of the tank body, which is caused by change of the inclination angle of the tank body of the mixing vehicle due to external reasons.
Description
Technical field
The utility model relates to concrete mixing and transporting car, a kind of specifically concrete mixing and transporting car material leak-proof device.
Background technology
The tank body dischargeable capacity of concrete mixing and transporting car is definite by agitator tank tank body size and agitator tank angle of inclination (being called for short the tank body inclination angle); Owing to, make the tank body inclination angle become the deciding factor of decision trucd mixer tank body dischargeable capacity with money trucd mixer tank body size relative fixed.Trucd mixer is in different gradient road traveling process, and the variation of running gradient can directly cause the variation at tank body inclination angle, thereby makes the tank body dischargeable capacity change.Going supreme slope or when jolting the road surface, the gradient strengthens, the tank body inclination angle reduces, and the tank body dischargeable capacity also reduces thereupon, in this process, tends to produce because of the tank body dischargeable capacity is not enough leak material.
The utility model content
For solving the leakage material problem that causes because of pavement behavior, the utility model provides a kind of concrete mixing and transporting car material leak-proof device.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of concrete mixing and transporting car material leak-proof device; Comprise rear portion frame, agitator tank and discharge bucket; Agitator tank jar mouth is inclined upwardly and is arranged on the frame of rear portion, is provided with discharge bucket at the jar mouthful place of agitator tank, also comprises hydraulic power unit, bidirectional hydraulic oil cylinder and striker plate; Striker plate is arranged on the jar mouthful place of agitator tank, and is connected with discharge bucket through rotating shaft; The bidirectional hydraulic oil cylinder is horizontally set on the frame of rear portion through the oil cylinder Connection Block; The piston rod of bidirectional hydraulic oil cylinder is connected through the swing-bar mechanism that bearing pin and striker plate are provided with; Hydraulic power unit is arranged in the frame of rear portion, and is connected with the bidirectional hydraulic oil cylinder through hydraulic oil pipe.
Hydraulic power unit in the utility model is provided with multi-way control valve, and hydraulic power unit is connected with multi-way control valve through connecting line.
The effect of the swing-bar mechanism in the utility model is that the horizontal reciprocating movement with the piston rod of bidirectional hydraulic oil cylinder is converted into striker plate rotation around the shaft.
Beneficial effect: the utility model is through being provided with striker plate at the jar mouth; And drive the folding of striker plate through the bidirectional hydraulic oil cylinder; Thereby play the subregion of agitator tank jar mouth is sealed; Improve trucd mixer tank body dischargeable capacity, avoid changing the generation that causes the not enough leakage material situation that is produced of tank body dischargeable capacity because of outside cause causes trucd mixer tank body inclination angle.

Fig. 1 is the structure chart of the utility model;
Reference numeral: 1, hydraulic power unit, 2, multi-way control valve, 3, hydraulic oil pipe, 4, the rear portion frame, 5, agitator tank, 6, the oil cylinder Connection Block, 7, the bidirectional hydraulic oil cylinder, 8, discharge bucket, 9, striker plate, 10, swing-bar mechanism, 11, rotating shaft.
The specific embodiment
As shown in the figure; A kind of concrete mixing and transporting car material leak-proof device comprises rear portion frame 4, agitator tank 5 and discharge bucket 8, and 5 jars of mouths of agitator tank are inclined upwardly and are arranged on the rear portion frame 4; Jar mouthful place at agitator tank 5 is provided with discharge bucket 8; Also comprise hydraulic power unit 1, bidirectional hydraulic oil cylinder 7 and striker plate 9, striker plate 9 is arranged on the jar mouthful place of agitator tank 5, and is connected with discharge bucket 8 through rotating shaft 11; Bidirectional hydraulic oil cylinder 7 is horizontally set on the rear portion frame 4 through oil cylinder Connection Block 6; The piston rod of bidirectional hydraulic oil cylinder 7 is connected through the swing-bar mechanism 10 that bearing pin and striker plate 9 are provided with; Hydraulic power unit 1 is arranged in the rear portion frame 4, and is connected with bidirectional hydraulic oil cylinder 7 through hydraulic oil pipe 3; Hydraulic power unit 1 is by multi-way control valve 2 controls that are provided with on it.
Go up a slope or approach when jolting the road surface when vehicle proceeds to,, thereby cause the tank body dischargeable capacity to reduce because the change of pavement behavior makes the inclination angle of agitator tank 5 change; Open hydraulic power unit 1 through multi-way control valve 2 this moment; The piston rod that drives bidirectional hydraulic oil cylinder 7 promotes swing-bar mechanism 10 and moves, and then striker plate 9 11 is rotated around the shaft, and 5 jars of notch portion zones of agitator tank are sealed; Thereby effectively increase the tank body dischargeable capacity, avoid Lou material.
