[0026] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0027] Among them, the same reference numerals in the drawings all refer to the same components.

[0028] Embodiment 1

[0029] As Figures 1-4 shown, the present utility model provides a dry-mixed mortar rough weighing machine, which includes a bottom plate 1. A support plate 2 is fixedly arranged on the top of the bottom plate 1. A pull plate with the other end fixedly connected to the bottom plate 1 is fixedly arranged on the back of the support plate 2. An aggregate hopper 7 and three support boards 3 are fixedly arranged on the front of the support plate 2. An electronic scale 4 is fixedly arranged on the top of the support board 3. A silo 5 is fixedly arranged on the top of the electronic scale 4. A discharge pipe 6 is communicated with the bottom of the silo 5. The inner bottom wall of the silo 5 is inclined. The connection position of the discharge pipe 6 on the silo 5 is located at the lowest point of the inclined surface of the inner bottom wall of the silo 5. Two shut-off valve assemblies are arranged on the front of the discharge pipe 6. The shut-off valve assembly includes a positioning sleeve 61, an insert piece 62, a threaded sleeve 63 and a threaded rod 64. The positioning sleeve 61 is fixed on the front of the discharge pipe 6. The insert piece 62 is inserted into the front of the positioning sleeve 61 and one end penetrates into the interior of the discharge pipe 6. A scale is sprayed on the top of the upper insert piece 62. The user can judge the depth of the insert piece 62 inserted into the discharge pipe 6 through the scale exposed outside the positioning sleeve 61, so as to roughly control the feeding rate. The threaded sleeve 63 is fixedly arranged on the opposite side of the two positioning sleeves 61. The threaded rod 64 is threadedly connected in the threaded sleeve 63, and one end thereof penetrates into the interior of the positioning sleeve 61 and contacts the insert piece 62.

[0030] In addition, the left and right sides of one end of the insert piece 62 located inside the discharge pipe 6 are respectively in contact with the left and right inner walls of the discharge pipe 6, and a receiving groove is formed on the rear side of the inner wall of the discharge pipe 6. One end of the insert piece 62 extends into the receiving groove.

[0031] One end of each of the three discharge pipes 6 extends into the aggregate hopper 7. A feeding pipe 8 is communicated with the bottom of the aggregate hopper 7. A track feeder 9 is fixedly arranged on the top of the bottom plate 1 and is located in front of the support plate 2. The feeding pipe 8 is located directly above the track feeder 9.

[0032] To sum up, when using this equipment, first pour the production raw materials of dry-mixed mortar into the three silos 5 respectively. At this time, both insert pieces 62 are completely closed;

[0033] According to the formula of the dry-mixed mortar required for the configuration, adjust the upper inserts 62 on the three discharge pipes 6 respectively. The lower inserts 62 remain completely closed. Adjust the approximate feeding rate through the scales on the inserts 62. For example, for the coarse weight of a certain dry-mixed mortar, the feeding weight ratio of Portland cement, fly ash and slag powder is 4:2:1. Then adjust the insertion ratios of the inserts 62 on the corresponding three discharge pipes 6 to no insertion, half insertion and one-fourth insertion. When it is known from the reading of the electronic scale 4 that the feeding weight of a certain material meets the standard, completely close the corresponding insert 62. By operating like this, natural mixing occurs during feeding, and the stirring time in the mixing tank can be reduced.

[0034] It should be specifically noted that after the insertion ratios of the inserts 62 on the discharge pipes 6 are adjusted, there is no need to adjust again if the formula remains unchanged. The upper inserts 62 are only for adjusting the feeding rate, while the lower inserts 62 are used to close and open the discharge pipes 6.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
