[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-3 As shown, this example provides a mortar specimen preparation device, including: a frame 100, a vibration component 200, and a limiting component 300.

[0020] The frame 100 has an opening on one side and a support plate 101 inside. The surface of the support plate 101 has a through part 102, and the mold 103 is placed on the support plate 101. The vibration component 200 includes a support frame 201 located below the support plate 101 and movable in the vertical direction. Multiple striking wheels 202 are rotatably mounted on the support frame 201. When the support frame 201 is at its highest point of travel, the striking wheels 202 pass through the through part 102, and the highest point is above the support plate 101, for striking the bottom surface of the mold 103. The limiting component 300 includes two sliders 301 located above the support plate 101 and movable in the length direction. A stop bar 302 is rotatably mounted on the sliders 301. When the mold 103 is placed inside the frame 100, the stop bar 302 contacts the side of the mold 103, limiting the side of the mold 103 and preventing it from moving during vibration.

[0021] Specifically, the support frame 201 is sleeved on the support rod 203, the lower end of the support rod 203 is installed on the side plate 204, the side plate 204 is installed inside the frame 100, and a spring 205 is sleeved on the support rod 203. The two ends of the spring 205 abut against the side plate 204 and the support frame 201 respectively, and are always in a compressed state. Under the action of the spring 205, the support frame 201 always has an upward tendency. When the mold 103 is pushed into the frame 100, one side of the mold 103 contacts the side of the striking wheel 202, and forces the support frame 201 to move downward. At this time, the spring 205 is further compressed until the striking wheel 202 is below the mold. Then, a downward force is applied to the support frame 201 at intervals to further compress the spring 205. When the force suddenly disappears, the support frame 201 will move upward under the action of the spring 205, thereby driving the striking wheel 202 to continuously strike the mold 103 and reduce the air bubbles in the mortar.

[0022] Specifically, both ends of the support frame 201 are provided with L-shaped plates 206. A rotating wheel 207 is located above the horizontal section of the L-shaped plate 206. Multiple top blocks 208 are provided around the rotating wheel 207 along its circumferential direction. The rotating wheel 207 is mounted on a rotating shaft 209, which is rotatably mounted on the frame 100, with one end connected to the output end of a power device. The power device is mounted on the frame 100 and can be a rotary motor. When the support frame 201 is at its highest point of travel, the horizontal section of the L-shaped plate 206 directly contacts the rotating wheel 207. When the mold 103... When placed in the frame 100, the support frame 201 is pressed down a certain distance. At this time, there is no contact between the horizontal section of the L-shaped plate 206 and the rotating wheel 207. Then, the rotating shaft 209 is driven to rotate by the power equipment, which drives the rotating wheel 207 to rotate. Then the top block 208 will contact the horizontal section of the L-shaped plate 206, forcing the support frame 201 to move further downward. The spring 205 is also further compressed. After the top block 208 disengages from the support frame 201, the support frame 201 will suddenly move upward under the action of the spring 205, thus striking the mold 103.

[0023] Specifically, the vertical section of the L-shaped plate 206 is provided with a vertically arranged elongated hole 210, and the rotating shaft 209 passes through the elongated hole 210 to avoid interference between the support frame 201 and the rotating shaft 209 during the up-and-down movement.

[0024] Specifically, the top of the frame 100 is provided with two through slots 106, and the stop bar 302 is inserted into the through slots 106. The length of the through slot 106 is greater than the length of the stop bar 302, so as to ensure that the stop bar 302 can be smoothly moved out of the through slot 106 when it rotates.

[0025] Specifically, the slider 301 is sleeved on the crossbar 303, which is installed on the frame 100 and arranged along its length. Before placing the mold 103 on the support plate 101, the two sliders 301 are moved along the axis of the crossbar 303. At this time, under the support of one end of the through groove 106, the stop bar 302 begins to rotate upward until the stop bar 302 is completely removed from the through groove 106, so that the mold 103 can be placed smoothly on the support plate 101. Then the slider 301 is reset, and the stop bar 302 passes through the through groove 106 again to limit the side of the mold 103.

[0026] Specifically, both ends of the frame 100 are provided with limiting strips 104. When the mold 103 is placed in the frame 100, the bottom surface of the limiting strip 104 contacts the top surface of the mold 103 to limit the top of the mold 103. The limiting strip 104 has a gap between its end and the opening, which makes it easier to put the mold 103 into the frame 100.

[0027] Specifically, a vertical pipe 105 is detachably installed on the top of the frame 100. When mortar needs to be poured into the mold 103, the vertical pipe 105 is located below the discharge port of the mixing tank, so that the mortar can fall smoothly into the mold 103. A level sensor, such as an ultrasonic level sensor, can be installed inside the frame 100 to monitor whether the mortar surface is level.

[0028] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
