Technical Field

The invention belongs to the technical field of dry-mixed mortar transportation equipment, and particularly relates to a sample type transportation device for transporting dry-mixed mortar.

Background

The dry-mixed mortar is a granular or powdery mixed material formed by mixing and physically mixing dry-screened aggregate, an inorganic cementing material, an additive and the like according to a certain proportion, when the dry-mixed mortar is used, a certain proportion of water can be directly added for stirring, and most of the dry-mixed mortar is stored in a storage tank for centralized transportation after being produced.

When the existing transportation equipment is used, most of the dry-mixed mortar after mixing is directly added into a storage tank, then a feed inlet is sealed to transport, but the dry-mixed mortar is composed of particles with different sizes and densities, vibration bumping or other reasons are received in the transportation process, the dry-mixed mortar is possibly subjected to layering segregation, most of the dry-mixed mortar after layering segregation does not have the original properties, the existing transportation equipment is used, most of the dry-mixed mortar is directly unloaded after being transported in place, and the dry-mixed mortar losing the properties after unloading is required to be filled and mixed again, the operation is complex, and the labor intensity of operators is increased.

In order to solve the problem that the dry-mixed mortar is isolated when being transported to a use area, most of the existing transportation equipment is internally provided with a mixing and stirring device, after the dry-mixed mortar is isolated, the dry-mixed mortar after unloading is added into the transportation equipment again, and then the mixing and stirring device is started, so that mechanized mixing and stirring are realized, most of the existing mixing and stirring devices adopt a stirring rod form to drive all raw materials in the dry-mixed mortar to be rotationally stirred in the transportation equipment so as to be mixed, however, in order to improve the transportation efficiency, the dry-mixed mortar transported by the transportation equipment at one time is more, the dry-mixed mortar is accumulated at the bottom of the transportation equipment under the action of gravity, a bridging phenomenon may occur at the bottom of the transportation equipment, and when the stirring rod rotates, in order to improve the stirring effect, the contact area between the stirring rod and the dry-mixed mortar is required to be larger, this causes a large resistance to the rotation of the stirring rod, which may cause a large load on the driving device for driving the stirring rod to rotate in a fully loaded state, and may cause damage to the device after a long time use, thereby reducing the service life of the device.

Most of the existing transportation devices can be respectively provided with a feeding valve pipe and a discharging valve pipe at the top end and the bottom end of the transportation devices, when discharging, most of the transportation devices can directly open the discharging valve pipe, then the gravity of dry-mixed mortar is utilized, the automatic downward movement is realized, the discharging valve pipe is discharged from the discharging valve pipe, but when the transportation devices are in actual use, the discharging speed of the dry-mixed mortar is relatively slow, and if the dry-mixed mortar is bridged or caked in the transportation devices, the discharging valve pipe can be possibly blocked, so that the discharging speed of the transportation devices is reduced, and the working efficiency of the transportation devices is reduced.
