Description

Technical Field

[0001] The utility model relates to the technical field related to concrete mixing, in particular to a simple mortar machine. Background Art

[0002] At present, many construction sites use concrete mortar machines. A mortar machine is a machine that mixes cement, sand, gravel and water to make a mortar mixture.

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0030] See also Figures 1 to 6 In the embodiment of the utility model, a simple mortar machine includes a base 1, a mortar bucket 3, a stirring mechanism, a threaded pushing member, a moving member, a gap feeding structure, and a rotating member.

[0031] The details are as follows, including:

[0032] See also Figure 1 , Figure 5, a base 1 and a mortar bucket 3 installed on the base 1, further comprising a discharge bucket 5 installed on the base 1, the discharge bucket 5 being communicated with the inner side of the mortar bucket 3, and further comprising a stirring mechanism installed in the mortar bucket 3;

[0033] A threaded pusher, mounted on the base 1 and connected to the stirring mechanism;

[0034] A moving part is installed on the base 1, and is connected to the moving part so as to be able to move in a direction parallel to the axial direction of the mortar barrel 3, so as to drive the stirring mechanism to intermittently change the stirring position;

[0035] The gap material discharge structure is installed in the material discharge barrel 5;

[0036] The rotating member is connected to the threaded pushing member and acts on the moving member and the intermittent feeding structure to work intermittently.

[0037] Among them, a mounting frame 2 is also installed on the base 1, and a driving member connected to the stirring mechanism is installed on the mounting frame 2. The driving member can be a motor 14. The motor 14 drives the stirring mechanism to perform stirring. The motor 14 is connected to a control unit, and the control unit controls the stirring to stop working after a certain period of time. The control unit includes but is not limited to a control button and an integrated circuit board installed on the mounting frame 2. The method of controlling the motor 14 belongs to a conventional design, and this embodiment does not make specific limitations on this.

[0038] In detail, in this embodiment, the simple mortar machine described in the utility model is adopted. When in use, the stirring mechanism is controlled to mix and stir the water, cement and sand in the mortar barrel 3. At the same time, the stirring mechanism drives the threaded pushing member to work synchronously, and cooperates with the interaction between the rotating member and the threaded pushing member to realize the intermittent rotation of the rotating member, and acts on the moving member and the intermittent unloading mechanism to work synchronously, driving the stirring mechanism to move along the axis parallel to the mortar barrel 3, intermittently changing the stirring position, and while the stirring mechanism moves, the intermittent unloading mechanism works to squeeze the raw materials in the discharge barrel 5 into the mortar barrel 3. When the raw materials can be fully stirred, it can also prevent excessive raw materials from generating load on the stirring mechanism, thereby reducing the electric power consumed by the stirring mechanism.

[0039] The stirring mechanism comprises a stirring shaft 6 , which is rotatably mounted in the mortar barrel 3 via a support plate 4 , a sleeve 7 is slidably provided on the stirring shaft 6 , and a stirring blade 10 is fixedly connected to the sleeve 7 .

[0040] Preferably, at least one group of strip-shaped limit sliding blocks 8 are formed on the stirring shaft 6 , and a strip-shaped limit sliding groove 9 slidably matched with the strip-shaped limit sliding blocks 8 is formed on the inner side of the sleeve 7 .

[0041] It should be noted that; when the first sleeve 7 moves, the strip limit groove 9 formed on the inner wall of the sleeve 7 cooperates with the limiting effect of the strip limit groove 9 to realize the movement of the sleeve 7 relative to the stirring shaft 6, and the strip limit slider 8 is slidably installed in the strip limit groove 9, thereby realizing the sliding connection between the sleeve 7 and the stirring shaft 6, and does not affect the rotation of the sleeve 7 with the rotation of the stirring shaft 6.

[0042] See also Figure 5 , Figure 6 The threaded pusher includes a second screw rod 16, which is rotatably mounted on the base 1. The second screw rod 16 is rotatably connected to the stirring shaft 6 through a first belt 15. A threaded sleeve 23 is threadedly connected to the second screw rod 16, and the threaded sleeve 23 is connected to the rotating member through a connecting block 25.

[0043] The rotating member includes a cylindrical member 17, and the cylindrical member 17 is rotatably mounted on the base 1, and a plurality of groups of limiting grooves 18 are formed on the cylindrical member 17;

[0044] It also includes a connecting sleeve 24 , which is arranged along the axial direction of the columnar member 17 and fixedly connected to the connecting block 25 . A ball 26 slidably matched with the limiting groove 18 is movably arranged inside the connecting sleeve 24 .

[0045] Specifically, when the stirring shaft 6 rotates, the second screw 16 is driven to rotate through the first belt 15. When the second screw 16 rotates, the threaded sleeve 23 is driven to make a linear motion along the axial direction of the second screw 16. When the threaded sleeve 23 moves, the connecting sleeve 24 is driven to move synchronously through the connecting block 25. When the connecting sleeve 24 moves, the ball 26 is driven to move synchronously. The ball 26 moves in a direction parallel to the axis of the columnar member 17, so that the columnar member 17 rotates in order to cooperate with the movement of the ball 26. The limiting groove 18 on the columnar member 17 is divided into a threaded groove and a horizontal groove. The ball 26 is in the horizontal groove. When the cylindrical member 17 moves inside, the cylindrical member 17 stops rotating. At this time, the stirring blade 10 does not change the stirring position and continues to mix and stir the mortar in the mortar barrel 3. When the ball 26 moves to the threaded groove, in order to cooperate with the moving trajectory of the ball 26, the ball 26 exerts an extrusion force on the cylindrical member 17, thereby causing the cylindrical member 17 to rotate. When the cylindrical member 17 rotates, it drives the moving member and the intermittent feeding mechanism to work at the same time, so that the moving member drives the stirring mechanism to intermittently change the stirring position, and the raw materials in the discharge barrel 5 are squeezed into the mortar barrel 3, ensuring that the mortar is fully stirred and can reduce the power consumed during stirring.

[0046] See also Figure 4 and Figure 5The moving member includes a first screw rod 12, which is rotatably mounted on the base 1, and the first screw rod 12 is rotatably connected to the columnar member 17 through a third belt 20;

[0047] It also includes a movable plate 11 , which is arranged in a U-shaped structure, one end of which is fixedly connected to the sleeve 7 , and the other end of which is threadedly connected to the first screw rod 12 .

[0048] The intermittent unloading mechanism includes an auger 13, which is rotatably installed in the discharge barrel 5. A transmission shaft 22 is rotatably installed on the base 1. The transmission shaft 22 is rotatably connected to the rotating shaft of the auger 13 through a bevel gear set 21. The columnar member 17 is rotatably connected to the transmission shaft 22 through a second belt 19.

[0049] Furthermore, when the above-mentioned columnar member 17 rotates, the transmission shaft 22 and the first screw 12 are driven to rotate through the second belt 19 and the third belt 20 respectively to achieve the transmission requirement. When the transmission shaft 22 rotates, the rotating shaft of the auger 13 is driven to rotate through the bevel gear set 21. When the auger 13 rotates, the blades squeeze the raw materials in the discharge barrel 5 into the mortar barrel 3. At the same time, when the first screw 12 rotates, it drives the movable plate 11 to move in a direction parallel to the axis of the mortar barrel 3, so as to drive the stirring mechanism to intermittently change the stirring position. When the raw materials can be fully stirred, it can also prevent excessive raw materials from generating load on the stirring mechanism, thereby reducing the electric power consumed by the stirring mechanism.
