Background

Along with the rapid development of economic construction in China, the engineering construction amount is continuously increased, the market demands for concrete are more and more, and a mixing plant and a mixing truck are used as concrete production and transportation equipment and are more and more widely applied.

The concrete mixing plant is mainly used for obtaining finished concrete after metering and mixing concrete raw materials such as sand stones, powder materials, additives and the like; during unloading, the concrete is collected by a collecting hopper, enters the feeding hopper of the mixer truck from the collecting hopper, and then enters the mixer truck through a helical blade in the mixing drum of the mixer truck; finally, transporting the concrete to the site by a mixer truck for construction;

at present, a discharge position device of a concrete mixing plant is generally fixed, and in the discharge process, because the vertical discharge speed of concrete is high and the impact force is large, the impact is often formed on a feed hopper of a mixer truck, the phenomenon of material splashing is easily generated, and the waste of concrete is caused; meanwhile, a turning transition exists between a receiving hopper of the mixer truck and the mixing drum, so that the concrete is decelerated in the blanking process to form accumulation; when the mixing plant unloads too fast, the condition of concrete flash will appear, cause the waste of concrete.

Detailed Description

The invention is explained in more detail below with reference to the figures and examples. The features and advantages of the present invention will become more apparent from the description. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments.

As shown in fig. 1-3, a novel discharging device includes a material collecting hopper 10, a transition hopper a20 and a transition hopper B30 which are sequentially sleeved from top to bottom, the transition hopper a20 is driven by a lifting mechanism 90 to lift relative to the material collecting hopper 10, the transition hopper B30 is driven by a turnover mechanism 80 to turn over relative to the transition hopper a20, a material discharging barrel 60 rotatably sleeved with the transition hopper B30 is arranged at the bottom of the transition hopper B30, the material discharging barrel is driven by a rotating mechanism 40 to rotate relative to the transition hopper B30, and material guiding blades 120 are arranged at 60 parts in the material discharging barrel.

Particularly, elevating system 90 and tilting mechanism 80 are hydro-cylinder, cylinder or electric putter, and in this embodiment, elevating system 90 is the hydro-cylinder, and tilting mechanism 80 is the cylinder, and the hydro-cylinder is installed and is being held together hopper 10 outer wall, and the execution end and the transition of hydro-cylinder fill A20 are connected, drive transition fill A20, transition fill B30 and feed cylinder 60 through the hydro-cylinder and wholly go up and down to the feeding height requirement of adaptation different truckles. When the transition hopper A20 ascends and descends relative to the material collecting hopper 10, the material outlet of the material collecting hopper 10 always extends into the transition hopper A20, so that material leakage of the transition hopper A20 in the process of moving up and down is prevented. In addition, the action of the oil cylinders is controlled by a synchronous loop so as to ensure that the transition bucket A20 is synchronous up and down. In order to improve the stability and accuracy of the lifting of the transition bucket A20, a guide rail 100 for lifting guide is arranged between the collecting hopper 10 and the transition bucket A20. Preferably, a protective cover 110 is sleeved outside the guide rail 100, the protective cover 110 may be a rubber bellows having a telescopic function, and the protective cover 110 is used for protecting the guide rail 100 from impurities such as concrete, thereby affecting the implementation of the up-and-down movement function.

The cylinder slope sets up, and the top of cylinder is articulated with the journal stirrup that sets up at transition fill A20 outer wall, and the bottom is articulated with the journal stirrup that sets up at transition fill B30 outer wall. Through the action of cylinder, drive transition fill B30, the upset of the whole relative transition fill A20 of feed cylinder 60, thereby feed cylinder 60's inclination under the adjustment, make it present the feeding angle similar with the churn of trucd mixer, and stretch into to the churn in, can accelerate the speed of unloading of concrete greatly, and effectively avoided the trucd mixer to connect the hopper flash, the risk of spilling the material, the unloading is more stable, and simultaneously, the impact to the trucd mixer feeder hopper has been reduced, the life of trucd mixer has been prolonged. In the process of overturning the transition hopper B30, the discharge port of the transition hopper A20 extends into the transition hopper B30 all the time so as to prevent the transition hopper B from leaking in the process of overturning and rotating.

The rotating mechanism 40 includes a motor, a rotating shaft driven by the motor to rotate, a gear rotating synchronously with the rotating shaft, and a gear ring 50 fixedly sleeved outside the charging barrel 60 and driven by the gear in a meshing manner. In the specific assembling process, an output shaft of the motor can be in direct transmission connection with the rotating shaft through the coupler, the rotating shaft can also be driven to rotate through the belt transmission mechanism or the gear transmission mechanism, and moreover, when the output shaft of the motor is in vertical transmission with the rotating shaft, the bevel gear mechanism can be applied. In addition, a gear in meshing transmission with the gear ring can also be directly arranged on the output shaft of the motor. In summary, all the transmission schemes selected according to the layout are included in the protection scope of the present technical scheme because of the basic common knowledge of mechanical transmission, and of course, each transmission member is rotatably supported by a bearing, which is common knowledge and will not be described in detail herein. In the process of gear and gear ring meshing transmission, lubricating grease is coated so as to ensure the smoothness of meshing transmission.

The material guiding blades 120 are spirally arranged, and may be integrally arranged or arranged in a sectional manner. In the unloading process, the lower feed cylinder is driven to rotate by the rotating mechanism, so that the concrete enters the mixing cylinder of the mixer truck in a spiral motion state, the concrete can enter the mixer truck in a faster and more stable material flow state, and the phenomena of material blockage and material overflow are not easy to form.

Preferably, a protective cover 70 is covered outside the ring gear 50, and the gear is located inside the protective cover 70. The protective cover is used for protecting the gear ring and the gear from being polluted by sundries.

In addition, wear-resisting material is selected for use to the inner wall of feed cylinder and guide blade down, perhaps sets up wear-resisting welt on the inner wall of feed cylinder and the surface of guide blade down. So as to ensure the wear resistance of the two, thereby reducing the wear generated in the blanking process.

When the concrete feeding device is used in concrete, the discharging device is preferably matched with a concrete mixing plant for use, the material collecting hopper is fixed on a platform of the mixing plant and used for receiving concrete feeding of a mixing main machine, and the concrete enters a mixing drum of a mixing truck after passing through the transition hopper A, the transition hopper B and the feeding drum.

In conclusion, by adopting the discharging device, the upper position and the lower position and the angle of the discharging barrel can be adjusted, so that the requirements of different heights of the feeding hopper and different angles of the stirring barrel of the stirring truck can be met, and the problems that the stirring truck is easy to spill and overflow when receiving materials are avoided.
