Description

Technical field:

[0002] The utility model relates to a dry-mixed mortar discharging mechanism. Background technology:

[0004] Dry-mix mortar (also called dry-powder mortar in the early days) is usually called hydraulic cement mixed mortar. It refers to a granular or powdery material that is physically mixed in a certain proportion of dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers). It is transported to the construction site in bagged or bulk form (for example, with the help of a dry-mix mortar transport vehicle) and can be used directly after adding water and mixing.

[0005] At present, when loading dry-mixed mortar onto a dry-mixed mortar transport vehicle, the dry-mixed mortar transport vehicle is directly moved to the bottom of the dry-mixed mortar storage tank in the production workshop, and the feed port on the top of the dry-mixed mortar transport vehicle is directly opposite to the discharge port at the bottom of the dry-mixed mortar storage tank. Then, the valve of the discharge port at the bottom of the dry-mixed mortar storage tank is opened to allow the dry-mixed mortar to fall into the dry-mixed mortar transport vehicle. However, when discharging the dry-mixed mortar storage tank, due to the certain distance between the discharge port at the bottom of the dry-mixed mortar storage tank and the feed port on the top of the dry-mixed mortar transport vehicle, the dry-mixed mortar is prone to partially scatter around the feed port on the top of the dry-mixed mortar transport vehicle when it falls, causing waste; at the same time, dust is generated when the dry-mixed mortar falls, which easily affects the environmental quality of the production workshop. For this reason, it is necessary to make improvements to the above-mentioned technical problems, and this case is thus born. Utility model content:

[0007] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a dry-mix mortar discharging mechanism.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a dry-mixed mortar discharging mechanism, comprising a dry-mixed mortar storage tank vertically installed on a supporting frame, the bottom discharge port of the dry-mixed mortar storage tank is connected to a discharge pipe, the lower end of the discharge pipe is fixed with a protective cover for covering the outside of a feed port arranged on the top of a dry-mixed mortar transport vehicle, the top and bottom of the protective cover are open, the inner cavity of the protective cover is connected to the discharge pipe, and the upper end of the protective cover is connected to a dust removal assembly.

[0009] Furthermore, a ring-shaped abutment flange is horizontally fixed to the inner side wall of the protective cover, and the abutment flange is coaxially arranged with the protective cover. The bottom surface of the abutment flange is used to abut against the end surface of the feed port on the top of the dry-mixed mortar transport vehicle, and the inner diameter of the abutment flange is the same as the inner diameter of the feed port on the top of the dry-mixed mortar transport vehicle.

[0010] Furthermore, the dust removal assembly includes an annular dust removal groove arranged above the abutting flange, the groove of the dust removal groove faces the inner edge of the abutting flange, and the dust removal groove is connected to the dust suction pump through a pipeline penetrating the side wall of the protective cover.

[0011] Furthermore, the discharge pipe is a telescopic hose.

[0012] Furthermore, the protective cover is in the shape of a frustum with a small diameter at the upper end and a large diameter at the lower end.

[0013] Furthermore, a discharge control valve is provided at the bottom discharge port of the dry-mixed mortar storage tank.

[0014] Compared with the prior art, the utility model has the following effects: the utility model has a simple and reasonable structural design, and the distance between the discharge port at the bottom of the dry-mixed mortar storage tank and the feed port on the top of the dry-mixed mortar transport vehicle is compensated by the discharge pipe, and the protective cover is arranged on the outside of the feed port on the top of the dry-mixed mortar transport vehicle, which effectively avoids the dry-mixed mortar scattering outside the feed port on the top of the dry-mixed mortar transport vehicle during discharge. At the same time, dust removal is carried out with the help of dust removal components to reduce dust dispersion, effectively improving the environmental quality of the production workshop.
