DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5The utility model provides a technical solution: a quantitative water adding mechanism for a concrete mixer, comprising a mounting plate 1, a mounting bolt 2, a fixing splint 3, a supporting column 4, a fixing column 5, a water adding cylinder 6, a liquid level sensor 7, a transparent observation window 8, an electric valve 9, a connecting mechanism 10, a connecting plate 11, a spring 12, a movable block 13, a protrusion 14, a limiting column 15 and a positioning block 16.

[0029] When using the quantitative water adding mechanism for the concrete mixer, Figure 1 and Figure 2 As shown, when in use, firstly, the mounting plate 1 is clamped on the housing of the mixer, and then the mounting bolts 2 threadedly connected to the left and right ends of the mounting plate 1 are rotated, and the mounting bolts 2 and the fixing clamping plates 3 are rotated, thereby driving the fixing clamping plates 3 to be extended and retracted inside the mounting plate 1, so that the fixing clamping plates 3 are clamped on the housing of the mixer, thereby facilitating the fixing of the mounting plate 1 on the mixer, and convenient for disassembly and assembly. After the installation is completed, when water needs to be added to the mixer, firstly, sufficient water is added to the water adding cylinder 6, and then the required water volume is set by the central processor according to the amount of raw materials such as cement, sand and gravel. A liquid level sensor 7 is fixedly installed on the upper end of the water adding cylinder 6, and the sensing element at the lower end of the liquid level sensor 7 extends into the water inside the water adding cylinder 6;

[0030] Then the central processor controls to open the electric valve 9, at which time the water in the water adding cylinder 6 is added to the mixer through the electric valve 9, and the raw water is mixed and stirred by the mixer, and the water level is monitored by the liquid level sensor 7. In addition, a transparent observation window 8 is provided on the front side of the water adding cylinder 6, and a scale code is provided on the front side of the water adding cylinder 6. The water volume in the water adding cylinder 6 can be directly observed by referring to the scale code through the transparent observation window 8. When the liquid level sensor 7 detects that the water volume has been added to the set amount, the central processor controls to close the electric valve 9 to stop adding water, thereby achieving the effect of quantitative water addition, which is very convenient to use.

[0031] In addition, if Figure 3 , Figure 4 and Figure 5As shown, when the mixer needs to work continuously, it is necessary to add raw materials such as cement, sand and gravel into the mixer again. Combined with the setting of the connecting mechanism 10, the connecting mechanism 10 includes a connecting plate 11 fixedly connected to the upper right end of the support column 4, a spring 12 fixedly connected to the inner side of the connecting plate 11, a movable block 13 fixedly connected to the movable end of the spring 12, and a protrusion 14 in a "T"-shaped structure. By pulling the limiting column 15, the limiting column 15 drives the movable block 13 to move in the middle of the connecting plate 11, and the movable block 13 drives the protrusion 14 to slide between the connecting plate 11, thereby improving the stability of the movement of the movable block 13. At this time, the movable block 13 squeezes the spring 12, causing the spring 12 to undergo elastic deformation, and the upper end of the limiting column 15 is separated from the positioning block 16, thereby releasing the limit between the fixed column 5 and the support column 4;

[0032] After the fixing column 5 is removed, the water adding cylinder 6 can be prevented from being located above the stirring, causing interference between the water adding cylinder 6 and the water adding cylinder 6 when adding raw materials. After the raw materials are added, the fixing column 5 is rotated on the upper end of the supporting column 4 to drive the water adding cylinder 6 to be placed above the mixer to add water.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
