Description

Technical Field

[0001] The utility model relates to the technical field of sand-based permeable bricks, and more specifically, to a mixing device for producing sand-based permeable bricks. Background Art

[0002] Sand-based permeable bricks refer to road paving bricks that are made of fine sand as the main raw material, mixed with cementitious materials, pressed and solidified at room temperature, and have excellent permeability. Sand-based permeable bricks have good water permeability and air permeability; the dense surface can prevent mud, ash and other tiny objects from blocking the holes, and the cleaning and maintenance are simple, with long-lasting permeability; it has high-strength wear resistance and weather resistance.

A discharge port is opened in the center of the bottom of the mixing cylinder. A driving motor is arranged in the center of the top surface of the mixing cylinder. The output end of the driving motor is connected to an agitator located inside the mixing cylinder. When the agitator rotates to perform mixing, the device drives the horizontal rotating rod to rotate through the cooperation of the driving gear and the driven gear, and drives the lifting plate and the lifting rod to reciprocate in the vertical direction through the action of the eccentric wheel. Through the action of the lifting rod, not only the raw materials are stirred by turbulence, but also the raw materials on different levels can interact with each other, thereby quickly achieving the mixing of the raw materials and improving the mixing quality and mixing efficiency.

[0004] Similar to the mixing equipment for producing sand-based permeable bricks mentioned above, the raw materials cannot be screened before mixing, which easily causes a large amount of lumps or substandard raw materials to enter the mixing barrel, reducing the production quality of sand-based permeable bricks.

[0035] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Refer to the attached drawings in the specification Figure 1 to Figure 5 The embodiment of the utility model provides a mixing device for producing sand-based permeable bricks, comprising:

[0037] A mixing barrel 1, the top of which is open and fixed with a bracket 11;

[0038] The stirring mechanism 2 extends into the stirring barrel 1 from the bottom of the stirring barrel 1;

[0039] The screening mechanism 3 is slidably disposed above the bracket 11;

[0040] The vibration mechanism 4 is arranged between the bottom of the screening mechanism 3 and the bracket 11, and includes a lower transmission plate 41 and an upper transmission plate 42. The lower transmission plate 41 is rotatably mounted on the bracket 11 through a bearing. The lower transmission plate 41 is transmission-connected to the top end of the stirring mechanism 2. The top surface of the lower transmission plate 41 is located on the first circumference and is evenly distributed with lower embedded grooves. Lower transmission balls 43 are rotatably embedded in the lower embedded grooves. The upper transmission plate 42 is fixedly arranged at the bottom of the screening mechanism 3. The bottom surface of the upper transmission plate 42 is located on the second circumference and is evenly distributed with upper embedded grooves. Upper transmission balls 44 are rotatably embedded in the upper embedded grooves. The second circumference is coaxial with the first circumference and has the same radius.

[0041] In this embodiment, when the raw materials are stirred, the raw materials are first put into the screening mechanism 3, and then the stirring mechanism 2 is started. While the stirring mechanism 2 stirs the raw materials in the stirring barrel 1, it also drives the lower transmission disc 41 of the vibration mechanism 4 to rotate, so that the lower transmission disc 41 and the upper transmission disc 42 rotate relative to each other. During the rotation of the lower transmission disc 41, the lower transmission balls 43 and the upper transmission balls 44 are continuously squeezed and interlaced, so that the screening mechanism 3 vibrates up and down continuously, thereby improving the screening efficiency of the raw materials, effectively preventing the agglomerated or unqualified raw materials from entering the stirring barrel 1, and thereby improving the quality of the sand-based permeable bricks.

[0042] In a preferred embodiment, if Figure 1As shown, a support leg 12 is fixedly connected to the bottom of the mixing barrel 1 for supporting the mixing barrel 1 .

[0043] In a preferred embodiment, if Figure 3 As shown, the support 11 is cross-shaped, has high support strength, and a relatively small area, and has little impact on the raw materials falling after screening.

[0044] In a preferred embodiment, if Figure 2 As shown, the stirring mechanism 2 includes a stirring shaft 21 arranged in the stirring barrel 1, the stirring shaft 21 is located on the axis of the stirring barrel 1, the bottom end of the stirring shaft 21 is rotatably connected to the bottom of the stirring barrel 1 through a sealed bearing, and the top end is fixedly connected to the lower transmission plate 41, and a plurality of stirring plates 22 are evenly distributed along the circumferential direction on the side wall of the stirring shaft 21. A reduction motor 23 for driving the stirring shaft 21 to rotate is arranged at the bottom of the stirring barrel 1, and the output torque is large and the stirring effect is good.

[0045] In a preferred embodiment, if Figure 4 and Figure 5 As shown, the screening mechanism 3 includes a screening barrel 31 arranged above the bracket 11, and a plurality of vertical slide bars 32 are evenly distributed on the periphery of the screening barrel 31. A slide groove 33 corresponding to the slide bar 32 is fixedly provided on the top of the bracket 11, and the slide bar 32 is slidably connected to the corresponding slide groove 33. A first sieve hole 34 is provided at the bottom of the screening barrel 31.

[0046] In this embodiment, after the raw materials are put into the screening barrel 31, the raw materials that meet the particle size requirements fall through the first sieve hole 34, and the raw materials that do not meet the particle size requirements are retained in the screening barrel 31. The vibration mechanism 4 drives the screening barrel 31 to vibrate continuously up and down along the chute 33 at the bottom of the screening barrel 31, thereby improving the screening efficiency of the screening barrel 31. The screening mechanism 3 ensures the production quality of the sand-based permeable bricks.

[0047] In a preferred embodiment, if Figure 4 and Figure 5 As shown, a plurality of placement slots 35 are evenly distributed along the circumferential direction in the screening barrel 31, and first sieve holes 34 are evenly distributed at the bottom of the placement slots 35. An over-diameter barrel 36 is detachably embedded in the placement slots 35, and a second sieve hole 37 is opened at the bottom of the over-diameter barrel 36 corresponding to the first sieve hole 34. The configuration of the over-diameter barrel 36 in the screening barrel 31 greatly improves the convenience of taking out the over-diameter raw material.

[0048] In a preferred embodiment, a lifting handle is fixedly provided on the top of the over-diameter barrel 36 to facilitate taking the over-diameter barrel 36 out of the screening barrel 31 .

[0049] In a preferred embodiment, if Figure 5 As shown, a limiting mechanism 5 is provided on one side of the top of the over-diameter barrel 36 in the placement groove 35;

[0050] The limiting mechanism 5 includes a limiting plate 51, and a limiting groove 52 is opened on one side of the placement groove 35 located at the top of the over-diameter barrel 36. One side of the limiting plate 51 is embedded in the limiting groove 52 and is slidably connected to the limiting groove 52. An extrusion slope 53 is arranged on the side of the limiting plate 51 extending out of the limiting groove 52. The extrusion slope 53 is inclined from top to bottom toward the side away from the limiting plate 51, and a support spring 54 is arranged between the side of the limiting plate 51 away from the extrusion slope 53 and the limiting groove 52.

[0051] In this embodiment, when the over-diameter barrel 36 is inserted into the placement groove 35, its bottom squeezes the squeezing slope 53 to retract the limit plate 51 into the limit groove 52. After the over-diameter barrel 36 is completely embedded in the placement groove 35, one side of the limit plate 51 extends out of the placement groove 35 under the action of the support spring 54 and blocks the top of one side of the over-diameter barrel 36, thereby improving the stability of the placement of the over-diameter barrel 36. When taking out the over-diameter barrel 36, an auxiliary tool such as a flat-blade screwdriver or a push rod pushes the limit plate 51 into the limit groove 52, lifts the over-diameter barrel 36 upward a little, and the top edge of the over-diameter barrel 36 is higher than the limit plate 51, then the auxiliary tool can be released, and the over-diameter barrel 36 can be taken out, which is convenient to operate.

[0052] In a preferred embodiment, if Figure 3 and Figure 5 As shown, a mounting groove 38 is provided at the center of the bottom of the screening barrel 31, and the upper transmission disc 42 is fixedly arranged in the mounting groove 38, and the depth of the mounting groove 38 is not greater than the thickness of the upper transmission disc 42. The upper transmission disc 42 is firmly installed, and the vibration transmission effect of the screening barrel 31 is good.

[0053] In a preferred embodiment, if Figure 3 As shown, the lower transmission balls 43 and the upper transmission balls 44 have the same radius and the same number, thereby ensuring the vibration effect of the lower transmission balls 43 and the upper transmission balls 44 cooperating with each other.

[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
