Technical Field

[0001] This utility model relates to the technical field of mortar mixing devices, specifically an anti-caking mortar mixing device. Background Technology

[0002] A mortar mixer is a piece of equipment used in construction engineering to uniformly mix cement, sand, water, and various additives (such as lime paste, fly ash, plasticizers, etc.) to make mortar. It is an indispensable machine for masonry, plastering, floor leveling and other processes.

[0003] In actual use, mortar mixers are prone to clumping due to moisture-affected materials, resulting in agglomeration during mixing. For example:

[0004] 1. The cement had partially become damp and clumped before use, and was not fully broken up after being put into the mixer;

[0005] 2. There are instances where wet sand forms localized clumps, which quickly solidify into small hard lumps upon contact with cement;

[0006] Therefore, in order to avoid the above situation leading to caking, a mortar mixing device that prevents caking is provided. Utility Model Content

[0007] The purpose of this invention is to provide a mortar mixing device that prevents caking, in order to solve the problems mentioned above.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a mortar mixing device for preventing caking, comprising a mixing assembly consisting of a mixing drum, a reduction motor, a mixing shaft, a cross-shaped top seat, and forced mixing rods.

The T-shaped slot is opened on the top of the straight groove type rotating seat and completely penetrates the bottom of the straight groove type rotating seat. The inclined guide screen frame is vertically slidably installed on the inner side of the upper half of the T-shaped slot.

[0014] The inclined guide screen frame is inclined as a whole, and the two sides of the inclined guide screen frame protrude to the outer sides of the straight groove type rotating seat. By pouring cement and sand into the inner side of the high part of the inclined guide screen frame, the cement and sand roll down along the inclined trajectory of the inclined guide screen frame, thereby realizing the screening operation of cement and sand by the inclined guide screen frame.

[0015] As a further embodiment of this utility model: the vibration unit includes a central column, a hemispherical block, an arc-shaped fixing block, and a vibration spring;

[0016] The arc-shaped fixing blocks are symmetrically fixed on both sides of the outer wall of the straight groove rotating seat and located at the bottom of the inclined guide screen frame.

Multiple hemispherical blocks are provided, and the multiple hemispherical blocks are evenly distributed in a ring and fixed to the bottom end of the central column.

[0018] The distribution trajectory of the hemispherical block is located in the rotation area of ​​the four arms of the cross-shaped top seat, and the top of the four arms of the cross-shaped top seat has an arc surface structure. The rotating cross-shaped top seat contacts and squeezes the hemispherical block to realize the up-and-down reciprocating vibration of the inclined guide screen frame.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5In this embodiment of the present invention, a mortar mixing device for preventing caking includes a mixing assembly 1 consisting of a mixing tank 101, a reduction motor 102, a mixing shaft 103, a cross-shaped top seat 104, and forced mixing rods 105. The reduction motor 102 is installed at the bottom of the mixing tank 101, and the mixing shaft 103 passes through the inside of the mixing tank 101 to the bottom of the mixing tank 101 and is fixedly connected to the output end of the reduction motor 102. The cross-shaped top seat 104 is fixed to the top of the mixing shaft 103. Multiple forced mixing rods 105 are arranged in a ring around the mixing shaft 103 and fixed to the bottom of the cross-shaped top seat 104. A fixing ring seat 106 is fixed to the outer side of the top of the mixing tank 101. A screening assembly 2 is installed on the mixing tank 101 through the fixing ring seat 106. The screening assembly 2 is used for feeding and screening cement and sand.

[0034] Screening assembly 2 includes a feeding unit and a vibration unit;

[0035] The feeding unit is used to provide material guiding and screening operations for cement and sand.

[0036] The vibration unit is used to provide vibration force for the screening of the feeding unit;

[0037] The feeding unit includes a straight groove type rotary seat 201, a T-shaped groove 202, and an inclined guide screen frame 203;

[0038] The straight groove type rotating seat 201 is distributed on the top of the mixing tank 101 and is rotatably connected to the outside of the fixed ring seat 106. The T-shaped groove 202 is opened on the top of the straight groove type rotating seat 201 and completely penetrates the bottom of the straight groove type rotating seat 201. The inclined guide screen frame 203 is vertically slidably installed on the inner side of the upper half of the groove of the T-shaped groove 202.

[0039] The inclined guide screen frame 203 is inclined as a whole, and the two sides of the inclined guide screen frame 203 protrude to the outer sides of the straight groove type rotary seat 201. By pouring cement and sand into the inner side of the high position of the inclined guide screen frame 203, the cement and sand roll down along the inclined trajectory of the inclined guide screen frame 203, thereby realizing the screening operation of cement and sand by the inclined guide screen frame 203.

[0040] The vibration unit includes a central column 205, a hemispherical block 206, an arc-shaped fixing block 207, and a vibration spring 208;

[0041] Arc-shaped fixing blocks 207 are symmetrically fixed on both sides of the outer wall of the straight groove type rotary seat 201 and located at the bottom of the inclined guide screen frame 203. Four vibration springs 208 are provided. The four vibration springs 208 are symmetrically fixed to the top of the two arc-shaped fixing blocks 207 respectively, and the top of the vibration springs 208 is fixedly connected to the bottom of the inclined guide screen frame 203. The vibration springs 208 provide vibration support for the inclined guide screen frame 203.

[0042] The central column 205 is fixed at the middle of the bottom end of the inclined guide screen frame 203 and extends downward to the top of the cross-shaped top seat 104. Multiple hemispherical blocks 206 are provided, and the multiple hemispherical blocks 206 are evenly distributed in a ring and fixed at the bottom end of the central column 205.

[0043] The distribution trajectory of the hemispherical block 206 is located in the rotation area of ​​the four arms of the cross-shaped top seat 104, and the top of the four arms of the cross-shaped top seat 104 has an arc surface structure. The rotating cross-shaped top seat 104 and the hemispherical block 206 contact and squeeze to realize the up and down reciprocating vibration of the inclined guide screen frame 203.

[0044] In this embodiment, it should be noted that the straight groove type rotating seat 201 does not completely cover the top of the mixing tank 101. Water or additives can be added and the mixing situation can be observed at the gap between the straight groove type rotating seat 201 and the top of the mixing tank 101. In addition, the bottom of the inner wall of the upper half of the T-shaped groove 202 is inclined, and the inclination angle matches the inclination angle of the inclined guide screen frame 203. Under normal conditions, there is a gap between the bottom of the inclined guide screen frame 203 and the bottom of the inner wall of the upper half of the T-shaped groove 202, which provides space for the inclined guide screen frame 203 to move up and down. At this time, the horizontal height of the lowest point of the hemisphere 206 is slightly lower than the horizontal height of the top of the cross-shaped top seat 105. That is, when there is no material on the top of the inclined guide screen frame 203, the rotating cross-shaped top seat 105 can still squeeze the hemisphere 206, but the vibration amplitude of the inclined guide screen frame 203 is smaller at this time.

[0045] When feeding cement and sand, the cement and sand are poured into the inner side of the high end of the inclined guide screen frame 203 by manual labor or feeding device (such as conveyor belt or loader). At this time, the cement and sand will roll down along the inclined trajectory of the inclined guide screen frame 203 under its own weight. When the cement and sand come into contact with the screen holes on the inclined guide screen frame 203, qualified cement and sand will fall into the mixing tank 101 through the screen holes, while the lumpy materials in the cement and sand that have clumped due to moisture will remain on the inclined guide screen frame 203 and eventually fall out through the opening at the low end of the inclined guide screen frame 203.

[0046] At the same time, the geared motor 102 synchronously drives the stirring shaft 103 and the cross-shaped top seat 104 to rotate. The cross-shaped top seat 104 drives multiple forced stirring rods 105 to rotate in a circle to stir the material inside the stirring tank 101. (It should be noted that the stirring component 1 is a common forced mixer on the market, and its stirring principle is exactly the same. It will not be described in detail here.)

[0047] Meanwhile, the inclined guide screen frame 203 will move downward a certain distance under the pressure of cement and sand, so that the bottom horizontal height of the hemispherical block 206 is lower than the top horizontal height of the cross-shaped top seat 104. When the cross-shaped top seat 104 rotates, the arc surface of its support arm can contact the downward-moving hemispherical block 206 and compress it. Under this compressive force, the inclined guide screen frame 203, the central column 205, and the hemispherical block 206 move upward as a whole. When the support arm separates from the hemispherical block 206, the inclined guide screen frame 203, the central column 205, and the hemispherical block 206 move downward again under their own weight and the gravity of the material. This reciprocating operation can realize the up-and-down reciprocating vibration of the inclined guide screen frame 203. Through the vibration of the inclined guide screen frame 203, the speed at which cement and sand roll downward can be further increased, while improving the screening efficiency and preventing cement and sand lumps from remaining on the top of the inclined guide screen frame 203.

[0048] By screening and removing lumps of cement and sand, the phenomenon of lumps appearing in the finished mortar can be effectively avoided.

[0049] Please refer to this carefully. Figures 2-5 The bottom of the inclined guide screen frame 203 is also fixed with a straight groove type limiting frame 204. The straight groove type limiting frame 204 is vertically slidably connected to the inner side of the lower half of the T-shaped groove 202, which is used to provide guidance and limitation for the vertical vibration of the inclined guide screen frame 203.

[0050] The screen holes on the inclined guide screen frame 203 are distributed in the middle area between the central column 205 and the straight groove type limiting frame 204.

[0051] In this embodiment: by vertically sliding the straight groove type limiting frame 204 to the inner side of the lower half of the T-shaped groove 202, the inclined guide screen frame 203 can maintain stable up and down vibration operation.

[0052] Meanwhile, the straight groove type limiting frame 204 can limit the downward falling cement and sand, preventing cement and sand from leaking out from the top port of the mixing drum 101.

[0053] Please refer to this carefully. Figures 1-4 A connecting block 209 is fixed to one end of the outer wall of the straight groove type rotary seat 201, and the connecting block 209 is located above the fixed ring seat 106;

[0054] The top of the fixed ring seat 106 is provided with a plurality of evenly distributed annular positioning holes 107, and the positioning holes 107 completely penetrate the bottom of the fixed ring seat 106.

[0055] A T-shaped pin 210 is inserted into the top of the connecting block 209. The vertical part of the T-shaped pin 210 passes through the connecting block 209 and a positioning hole 107 in sequence, which is used to realize the rotation locking of the straight groove type rotary seat 201.

[0056] In this embodiment: In actual operation, the orientation of the inclined guide screen frame 203 can be adjusted according to the location of the cement and sand. By pulling out the T-shaped pin 210 and separating it from the positioning hole 107, the entire screening component 2 can be rotated. Finally, the high point of the inclined guide screen frame 203 is oriented towards the location of the cement and sand. Then, the T-shaped pin 210 is reinserted into the positioning hole 107 at this location through the connecting pipe 209, and the orientation of the inclined guide screen frame 203 can be fixed, which facilitates the feeding operation.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
