Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically to a dry mixing machine for building construction mortar. Background Technology

[0002] In the construction industry, mortar is an important building material. It is usually formed by mixing a variety of building materials. Dry mixing involves mixing various dry materials evenly in advance, and then adding an appropriate amount of water as needed for mixing, which effectively prevents the dry materials from caking and causing uneven mixing.

[0003] Traditional dry-mixing methods for mortar mixing mainly rely on manual mixing or simple mechanical mixing. However, manual mixing often suffers from uneven mixing, excessive dust generation during the mixing process, time-consuming and labor-intensive operations, and low efficiency. Mechanical mixing, on the other hand, uses a simple mixing structure, which cannot ensure sufficient mixing between various dry materials, and its unreasonable mixing structure design leads to poor equipment stability during the mixing process.

[0004] In view of this, we propose a dry mixing machine for mortar in building construction to solve the existing problems. Utility Model Content

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a dry mixing machine for mortar in building construction, comprising:

[0027] Mixing chamber 1;

[0028] A first stirring shaft 2 is installed inside the mixing chamber 1. A first stirring paddle 3 is provided on the outer periphery of the first stirring shaft 2. One end of the first stirring paddle 3 is spirally connected to the outer periphery of the first stirring shaft 2. One end of the first stirring shaft 2 passes through the side wall of the mixing chamber 1 and is connected to a first driving device for driving the first stirring shaft 2 to rotate and drive the mortar to perform preliminary mixing.

[0029] The second stirring shaft 7 is arranged parallel to the first stirring shaft 2 in the mixing chamber 1. The second stirring shaft 7 is provided with a second stirring paddle 8 on its outer periphery. One end of the second stirring paddle 8 is spirally connected to the outer periphery of the second stirring shaft 7. One end of the second stirring shaft 7 passes through the side wall of the mixing chamber 1 and is connected to a second driving device, which is used to drive the second stirring shaft 7 to rotate and cooperate with the first stirring shaft 2 to make the mortar material fully mixed.

[0030] The first stirring paddle 3 and the second stirring paddle 8 are arranged alternately.

[0031] Furthermore, the first drive device and the second drive device are arranged opposite to each other at both ends of the mixing chamber 1 to ensure that the first mixing shaft 2 and the second mixing shaft 7 can uniformly drive the mortar material to mix in the mixing chamber 1, while maintaining the balance at both ends of the mixing chamber 1.

[0032] Furthermore, the first driving device includes a first motor base 5, on which a first stirring motor 6 is mounted. The output end of the first stirring motor 6 is connected to a first reducer 4, and the output end of the first reducer 4 is drivenly connected to the first stirring shaft 2.

[0033] Furthermore, the second drive device includes a second motor base 14, on which a second stirring motor 15 is mounted. The output end of the second stirring motor 15 is connected to a second reducer 13, and the output end of the second reducer 13 is drivenly connected to the second stirring shaft 7.

[0034] Furthermore, the top of the mixing chamber 1 is provided with a dust cover 18 that is sealed and connected to the mixing chamber 1. The dust cover 18 is provided with a feed inlet 16, which is connected to the mixing chamber 1.

[0035] Furthermore, the feed inlet 16 has two symmetrically arranged at both ends of the top surface along the length of the mixing chamber 1, and each feed inlet 16 is surrounded by a second baffle 17, the cross-sectional shape of the second baffle 17 being an inverted trapezoid.

[0036] Furthermore, the bottom of the mixing chamber 1 is provided with a discharge port 9 that communicates with the mixing chamber 1. A first bottom plate 10 and a second bottom plate 12 are respectively hinged to the two opposite side walls of the discharge port 9 along the length direction of the mixing chamber 1. The first bottom plate 10 and the second bottom plate 12 can rotate around the hinge axis, thereby closing or opening the discharge port 9.

[0037] Furthermore, the first base plate 10 is provided with a first locking member 101 on the side away from the hinge end, and the second base plate 12 is provided with a second locking member 121 corresponding to the first locking member 101 on the side away from the hinge end. The first locking member 101 is provided with a recessed locking hole, and the second locking member 121 is provided with a connecting member 122 that is slidably connected to the second locking member 121 and cooperates with the locking hole of the first locking member 101.

[0038] Furthermore, an elastic element 123 is provided between the connector 122 and the second locking element 121. One end of the connector 122 located inside the second locking element 121 is also connected to a pull rod 124, and the other end of the pull rod 124 passes through the second locking element 121 and is connected to a handle.

[0039] Furthermore, the discharge port 9 is located at the bottom center of the mixing chamber 1, and a first baffle 11 is provided on the outside of the discharge port 9.

[0040] The working principle of a dry-mixing machine for building mortar based on Embodiment 1 is as follows: During use, various mortar materials to be mixed are added through the feed inlets 16 on both sides of the top of the mixing chamber 1. The upper end of each feed inlet 16 is surrounded by an inverted trapezoidal second baffle 17, which helps the mortar materials enter the mixing chamber 1 evenly and quickly. Simultaneously, a dust cover 18 is provided above the mixing chamber 1 to reduce dust emission. During mixing, the first and second driving devices are activated, driving the first mixing shaft 2 and the second mixing shaft 7 to rotate in opposite directions. The first mixing shaft 2 and the second mixing shaft 7, along with the shafts, agitate the mortar materials. Because the first mixing shaft 3 and the second mixing shaft 8 are staggered, they cooperate to ensure that the mortar materials are fully mixed within the mixing chamber 1. The first and second driving devices are positioned opposite each other at both ends of the mixing chamber 1, driving the first mixing shaft 2 and the second mixing shaft 7 respectively. The second mixing shaft 7 not only helps the mortar to be mixed more evenly under the independent control of the two shafts, but also maintains the balance at both ends of the mixing chamber 1. After the mortar is fully mixed evenly, it is ready to be discharged from the discharge port 9. The discharge port 9 is provided with a first bottom plate 10 and a second bottom plate 12 that can open or close the discharge port 9. In the closed state, the first locking member 101 on the first bottom plate 10 and the second locking member 121 on the second bottom plate 12 are locked together by the connecting member 122. When unlocking, by pulling the handle, the connecting member 122 compresses the elastic member 123 and disengages from the locking hole of the first locking member 101, so that the first bottom plate 10 and the second bottom plate 12 rotate around the hinge shaft under the gravity of the mortar and separate to open the discharge port 9. During the discharge process, the first driving device and the second driving device drive the first mixing shaft 2 and the second mixing shaft 7 to rotate in the same direction, so that the first mixing paddle 3 and the second mixing paddle 8 can jointly push the mortar towards the discharge port 9 and discharge it from the discharge port 9.

[0041] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
