Description

Technical Field

[0001] The utility model relates to the technical field of mortar production, in particular to a raw material mixing device for mortar production. Background Technique

[0002] Mortar is usually used in construction projects and is a mixture for bonding building materials such as bricks and stones. It is mainly composed of water, cement, lime and sand, and sometimes other additives are added to improve its performance. During interior decoration, mortar is mostly produced on-site. Usually, raw materials such as cement and sand are put into a mixing drum, and then water is added for mixing and production.

[0003] Traditional mortar mixing drums are mostly arranged vertically. After the mortar is mixed and produced, workers need to hold the drum body and tilt the mixing drum to pour out the mortar. This process is time-consuming and laborious, and during the tilting process, if the operation is improper or the equipment itself is unstable, it is easy to cause the mixing drum to get out of control during the tilting process, resulting in the risk of injury to workers or damage to the equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a raw material mixing device for mortar production that is convenient for pouring mortar, effectively solving the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions.

[0006] A raw material mixing device for mortar production includes a mixing drum and a base. On both sides of the upper surface of the base, there are symmetrically fixed vertical frames that extend upward. A first rotating shaft is rotatably installed on the side of one of the vertical frames, and a second rotating shaft is rotatably installed on the side of the other vertical frame. The mixing drum is arranged between the two vertical frames. The first rotating shaft and the second rotating shaft are respectively fixed to the outer wall of the mixing drum. An adjusting mechanism is provided on one of the vertical frames, and the adjusting mechanism is used to drive the first rotating shaft to rotate.

[0007] Thus, after mixing is completed, by operating the adjusting mechanism, the first rotating shaft on one side is driven to rotate, and then the mixing drum is driven to rotate and tilt, facilitating the pouring out of the mixed mortar.

The worm is rotatably installed on the two brackets. The connecting shaft is fixed to one end of the first rotating shaft. The worm gear is fixedly sleeved on the connecting shaft and meshes with the worm correspondingly.

[0009] Further, a rocking disk is installed at one end of the worm, and the surface of the handle of the rocking disk is provided with anti-slip lines.

[0010] Further, a shaft rod is provided inside the mixing drum. The shaft rod extends vertically upward above the mixing drum. The part of the shaft rod inside the mixing drum is provided with mixing groups arranged in an array from top to bottom. A driving mechanism is provided above the mixing drum, and the driving mechanism is used to drive the shaft rod to rotate.

[0011] Further, the driving mechanism includes a suspension, a fixed seat, and a driving motor. The suspension is arranged above the mixing drum. The fixed seat is installed on the suspension.

[0016] 1. By screwing and adjusting the worm to rotate, the rotating worm meshes with and drives the worm wheel, and drives the first rotating shaft to rotate under the connection action of the connecting shaft. Furthermore, the mixing drum can be driven to rotate, facilitating the mixing drum to be rotated and adjusted to an inclined state, which is convenient for pouring out and using the produced mortar. The inclined adjustment process of the mixing drum is stable, time-saving, labor-saving and safe in operation, greatly facilitating the staff to produce mortar at the construction site.

[0017] 2. The present utility model uses the rotation of the worm to mesh with and drive the worm wheel and the first rotating shaft to rotate.

Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present utility model.

[0026] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] Please refer to Figures 1-4, a raw material mixing device for mortar production provided by the utility model includes a mixing barrel 1 and a base 2. On both sides of the upper surface of the base 2, vertical frames 21 extending upward are symmetrically fixed. A first rotating shaft 22 is rotatably installed on the side of one of the vertical frames 21, and a second rotating shaft 23 is rotatably installed on the side of the other vertical frame 21. The mixing barrel 1 is arranged between the two vertical frames 21. The first rotating shaft 22 and the second rotating shaft 23 are respectively fixed to the outer wall of the mixing barrel 1. An adjusting mechanism 3 is provided on one of the vertical frames 21, and the adjusting mechanism 3 is used to drive the first rotating shaft 22 to rotate.

[0028] When using this mixing device to produce mortar, the mixing barrel 1 is in a vertical state. The mortar raw materials are put into the mixing barrel 1 for stirring and mixing. After mixing, by operating the adjusting mechanism 3, the first rotating shaft 22 on one side is driven to rotate, and then the mixing barrel 1 is driven to rotate and tilt, which is convenient for pouring out the mixed mortar.

[0029] Specifically, the adjusting mechanism 3 includes a worm 32, a connecting shaft 33, a worm wheel 34 and a pair of brackets 31. The two brackets 31 are fixed to the side of the vertical frame 21. The worm 32 is rotatably installed on the two brackets 31. The connecting shaft 33 is fixed to one end of the first rotating shaft 22. The worm wheel 34 is fixedly sleeved on the connecting shaft 33 and meshes with the worm 32 correspondingly. By screwing and adjusting the rotation of the worm 32, the rotating worm 32 meshes and drives the worm wheel 34 and drives the first rotating shaft 22 to rotate under the connection action of the connecting shaft 33. Then the mixing barrel 1 can be driven to rotate, which is convenient for adjusting the mixing barrel 1 to a tilted state, facilitating the pouring out and use of the produced mortar. The tilting adjustment process of the mixing barrel 1 runs stably, the operation is time-saving, labor-saving and safe, which greatly facilitates the staff to produce mortar at the construction site.

[0030] The rotation of the worm 32 is used to mesh and drive the rotation of the worm wheel 34 and the first rotating shaft 22. By using the one-way transmission of the worm 32 and the worm wheel 34, the first rotating shaft 22 can be locked. When the worm 32 is not screwed and adjusted, it is ensured that the mixing barrel 1 will not deflect randomly, which helps to maintain the state of the mixing barrel 1 and improves the stability during the overall operation.

[0031] Specifically, a crank 321 is installed at one end of the worm 32. The surface of the handle of the crank 321 is provided with anti-slip lines. By holding the handle of the crank 321 and applying force to shake it, the worm 32 can be driven to rotate and adjust. The operation process is easy and labor-saving. In addition, anti-slip lines are provided on the handle to increase the friction with the hand and prevent slipping during the shaking process.

[0032] Specifically, a shaft rod 4 is provided inside the mixing drum 1. The shaft rod 4 extends vertically upward above the mixing drum 1. The part of the shaft rod 4 inside the mixing drum 1 is arranged with mixing groups 41 in an array from top to bottom. A driving mechanism 5 is provided above the mixing drum 1. The driving mechanism 5 is used to drive the shaft rod 4 to rotate. By operating the driving mechanism 5 to drive the shaft rod 4 to rotate, the rotating shaft rod 4 drives the mixing groups 41 to rotate synchronously, so as to mix the sand raw materials in the mixing drum 1.

[0033] Specifically, the driving mechanism 5 includes a suspension 51, a fixed seat 52 and a driving motor 53. The suspension 51 is arranged above the mixing drum 1. The fixed seat 52 is installed on the suspension 51. The driving motor 53 is fixed on the suspension 51 through the fixed seat 52. The output shaft of the driving motor 53 is fixedly connected to the top end of the shaft rod 4. By operating the driving motor 53, its output shaft drives the shaft rod 4 to rotate, providing drive for the mixing action.

[0034] During the specific mixing process, since the mixing groups 41 are distributed up and down, and the mixing effect of the mortar raw materials between the two mixing groups 41 is not ideal. To solve this problem, the present utility model makes the following improvements:

[0035] An electric push cylinder 6 extending vertically is fixed on the outer wall of the mixing drum 1. The end of the telescopic rod of the electric push cylinder 6 is vertically fixed with a connecting arm 61. The top end of the connecting arm 61 is fixed with a mounting seat 62. The suspension 51 is fixed on the side of the mounting seat 62. By the telescopic operation of the electric push cylinder 6, its telescopic rod can drive the whole driving mechanism 5 and the shaft rod 4 to be adjusted up and down under the fixed connection of the connecting arm 61 and the mounting seat 62, which is convenient for mixing the mortar raw materials between the two mixing groups 41 distributed up and down, improving the uniformity of raw material mixing, and further improving the production quality of mortar.

[0036] Specifically, each mixing group 41 includes four mixing rods 411. The four mixing rods 411 are arranged in an annular array on the shaft rod 4. Each mixing rod 411 is perpendicular to the shaft rod 4. The four mixing rods 411 arranged in an annular array are respectively on the four sides of the outer circumference of the mixing group 41, providing multiple mixing points, further improving the uniformity of raw material mixing.

[0037] Specifically, universal wheels 201 are respectively installed at the four corners of the lower surface of the base 2. The universal wheels 201 have a braking effect. By arranging the universal wheels 201, it is convenient to move the whole device, improving the flexibility of the device operation. In addition, when the mixing drum 1 is adjusted to an inclined state to pour the mortar, the whole device can be moved while pouring the mortar through the universal wheels 201, which can avoid the mortar from piling up too high and affecting the discharge of the mortar in the mixing drum 1. The universal wheels 201 have a braking effect, which is convenient for the device to be static and has high stability.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
