Moreover, the amount of slurry required for such mold products is usually quantitative. In this way, if the grouting amount cannot be effectively controlled, excessive grouting will easily lead to slurry overflow and even damage to the mold, and too little grouting will result in unqualified product quality.

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a grouting machine with controllable grouting amount, comprising a slurry tank (1), a tank cover (3) is installed on the slurry tank (1), a main support frame (4) is fixed below the slurry tank (1), and a stirring component for stirring slurry is installed on the slurry tank (1).

[0022] Furthermore, the stirring assembly comprises a first motor (2) and a stirring shaft (13), wherein the first motor (2) is installed at the center position of the upper end of the slurry tank (1), and the tank cover (3) is symmetrically arranged on both sides of the first motor (2), so that feeding can be performed on both sides at the same time, which is convenient for the feeding work of the device, and the stirring shaft (13) is fixedly connected to the output shaft of the first motor (2), and the stirring shaft (13) is arranged in a "U" shape at the lower end inside the slurry tank (1), so that the mixing and stirring work of the slurry inside the slurry tank (1) can be completed quickly and fully, and the sedimentation of the slurry inside the slurry tank (1) can also be avoided.

[0023] The lower flange of the slurry tank (1) is connected to a grouting body (5), the outer end of the grouting body (5) is equipped with a hydraulic cylinder (6), the interior of the grouting body (5) is equipped with a grouting sub-body (11), and the grouting sub-body (11) is connected to an adjustment component for adjusting the position of the grouting sub-body (11), and the outer end of the grouting sub-body (11) is provided with a slurry outlet (12).

[0024] Furthermore, the adjustment component includes a second motor (8) and a threaded rod (9), wherein the second motor (8) is fixed on the grouting body (5), and the threaded rod (9) is threadedly connected to the grouting sub-body (11), and the second motor (8) and the threaded rod (9) are both installed on the sub-support frame (7), and the sub-support frame (7) is fixed on the main support frame (4), which can not only ensure the stable working state of the second motor (8) and the threaded rod (9), but also provide support for the grouting body (5) and the grouting sub-body (11), thereby effectively ensuring the stability of the working state of the device.

[0025] Furthermore, the grouting auxiliary body (11) is driven by the threaded rod (9) to form a reciprocating structure in the grouting main body (5), which can change the combined size of the grouting auxiliary body (11) and the grouting main body (5), thereby adjusting the grouting amount, and the grouting auxiliary body (11) and the grouting main body (5) are sealed and connected via a rubber ring to ensure that no leakage occurs between the grouting auxiliary body (11) and the grouting main body (5).

[0026] A first one-way valve (14) is installed between the grouting body (5) and the slurry tank (1), and the slurry enters the grouting body (5) from the slurry tank (1). A second one-way valve (15) is fixed at the front end of the hydraulic cylinder (6), and the second one-way valve (15) is located in the grouting body (5). The slurry flows from the side connected to the first one-way valve (14) to the side of the third one-way valve (16). The third one-way valve (16) is fixed inside the grouting sub-body (11), and the slurry enters the grouting sub-body (11) from the grouting body (5).

[0027] Furthermore, a limiting sleeve (10) is fixed on the outside of the grouting sub-body (11), and the other end of the limiting sleeve (10) is annularly sleeved on the outside of the grouting main body (5), which can further strengthen the stable state of the grouting sub-body (11). The length of the limiting sleeve (10) is equal to the length of the grouting sub-body (11), and the position of the end of the grouting sub-body (11) inside the grouting main body (5) can be determined by the position of the limiting sleeve (10) on the outside of the grouting main body (5), thereby facilitating the determination of the grouting amount inside the grouting main body (5).

[0028] Furthermore, the second one-way valve (15) forms a movable structure in the grouting body (5) through the hydraulic cylinder (6), and the moving position of the second one-way valve (15) does not exceed the interface position between the slurry tank (1) and the grouting body (5), and the outer side of the second one-way valve (15) is sealed and connected to the grouting body (5) through a rubber ring, thereby ensuring that the grouting work proceeds normally.

[0029] Specifically, when using the grouting machine, firstly, the tank cover (3) on the slurry tank (1) is opened, slurry raw materials are added into the slurry tank (1), and then the first motor (2) is started to make the stirring shaft (13) stir the raw materials in the slurry tank (1), thereby forming the slurry required for grouting, and at the same time, the stirring shaft (13) is required to stir continuously to avoid precipitation of the slurry;

[0030] When grouting is performed, the grouting pipe is first connected to the grouting outlet (12), and then the grouting amount is determined. The second motor (8) can be started to rotate the threaded rod (9). When the threaded rod (9) is in the forward direction or rotating state, the grouting auxiliary body (11) is moved back and forth in the grouting main body (5). At the same time, the limiting sleeve (10) on the grouting auxiliary body (11) moves outside the grouting main body (5) to display the position of the end of the grouting auxiliary body (11) in the grouting main body (5), determine the size of the space in the grouting main body (5), and then determine the grouting amount;

[0031] Then, the second one-way valve (15) is moved in the grouting body (5) by means of the hydraulic cylinder (6). When the second one-way valve (15) is pushed forward, the slurry in the slurry tank (1) is drawn through the first one-way valve (14) and enters the grouting body (5). At this time, the slurry enters the grouting body (5) between the hydraulic cylinder (6) and the second one-way valve (15). The second one-way valve (15) is continuously pushed forward and is finally blocked by the end of the grouting auxiliary body (11).

[0032] Afterwards, the hydraulic cylinder (6) pulls the second one-way valve (15) to move backward, and the slurry in the grouting body (5) enters the front space of the grouting body (5) through the second one-way valve (15). As the second one-way valve (15) moves forward again, the slurry can be pushed forward and enter the grouting sub-body (11) through the third one-way valve (16). As the second one-way valve (15) continues to move forward and backward, the grouting body (5) and the grouting sub-body (11) are filled with slurry. As the second one-way valve (15) moves forward and backward, the slurry is transported to the connected pipeline through the slurry outlet (12). Finally, the slurry is injected into the mold through the grouting port on the external pipeline to complete the grouting work.

[0033] Since the stroke of the second one-way valve (15) is fixed each time, the grouting amount is fixed each time, so that the grouting amount can be controlled to ensure that the grouting work is carried out normally. Subsequently, the position of the grouting auxiliary body (11) can be changed according to the need for the grouting amount, thereby changing the grouting amount in the grouting main body (5);

[0034] The above has completed the working process of the grouting machine, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
