Description

Technical Field

[0001] This utility model relates to the technical field of dry mortar mixers, specifically a dry mortar mixing and feeding device. Background Technology

[0002] Dry mortar refers to a granular or powdery material that is physically mixed in a certain proportion with aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) that have undergone drying and screening. It is transported to the construction site in bagged or bulk form and can be used directly after being mixed with water.

[0003] The zero-gravity mixer is a commonly used equipment for mixing dry powder mortar. The horizontal cylinder of the zero-gravity mixer is equipped with dual-shaft rotating counter-rotating blades. The blades are at a certain angle to circulate and stir the material along the axial and radial directions, so that the material is quickly and evenly mixed.

[0004] The discharge port of the existing zero-gravity mixer is located in the middle area of ​​the horizontal cylinder. During the discharge operation, the auxiliary materials are discharged by rotating the blades. However, the material is moved in a circular motion by the blades, which leads to discontinuous discharge and easy residue. Based on this, a dry powder mortar mixing and feeding device is provided.

The end plates are symmetrically fixed at both ends of the horizontal cylinder and extend to the bottom of the horizontal cylinder. Two mixing paddles are distributed parallel to each other inside the horizontal cylinder and are rotatably connected to the end plates. The rotating shafts of the two mixing paddles pass through the outside of the end plates and are connected by transmission through the first parallel gearbox.

The circular conveying pipe is fixed to the end face of one end plate, and this end plate has a through hole that communicates with the U-shaped conveying pipe and the circular conveying pipe.

[0009] The spiral conveyor shaft is distributed inside the U-shaped conveyor pipe and extends to the inside of the circular conveyor pipe. One end of the central shaft of the spiral conveyor shaft is rotatably connected to the end plate near the first parallel gear box, and the other end passes through the circular conveyor pipe and is fixed to the output end of the discharge motor. The discharge motor is installed at the outer end of the circular conveyor pipe.

[0010] The discharge port is located at the bottom end of the circular conveying pipe;

[0014] The bottom of the horizontal cylinder has two symmetrical arc-shaped rotating grooves, which completely penetrate both sides of the U-shaped conveying pipe into the inner cavity of the horizontal cylinder.

[0015] Two arc-shaped valve plates are provided, and the two arc-shaped valve plates are slidably connected to the inner side of the two arc-shaped rotating grooves respectively. The two arc-shaped valve plates are attached to each other on the side closest to each other, which is used to form a distribution of the top opening of the U-shaped conveying pipe, thereby realizing the disconnection of the U-shaped conveying pipe from the horizontal cylinder.

[0016] The two arc-shaped valve plates extend to the outside of the U-shaped conveying pipe on opposite sides. The outer wall of the arc-shaped valve plate is formed with toothed grooves. The toothed roller is rotatably connected to the middle of the two end plates and located below the arc-shaped valve plate. The toothed roller matches the toothed grooves of the arc-shaped valve plate.

[0017] The two toothed rollers have their shafts extending to the outer end of the end plate and are connected by a second parallel gearbox.

[0030] 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.

[0031] Please see Figures 1-4 In this embodiment of the present invention, a dry mortar mixing and feeding device includes a zero-gravity mixer 1 consisting of a horizontal cylinder 101, an end plate 102, a mixing paddle 103, and a first parallel gearbox 104. The end plate 102 is symmetrically fixed at both ends of the horizontal cylinder 101 and extends to the bottom of the horizontal cylinder 101. Two mixing paddles 103 are distributed in parallel on the inner side of the horizontal cylinder 101 and are rotatably connected to the end plate 102. The rotating shafts of the two mixing paddles 103 pass through the outside of the end plate 102 and are connected by transmission through the first parallel gearbox 104. The first parallel gearbox 104 is fixed to the outer end of one end plate 102 by a bracket. A feeding component 2 is provided in the lower middle part of the horizontal cylinder 101. The feeding component 2 is used to convey the mixed material out.

[0032] The feeding assembly 2 includes a U-shaped conveying pipe 201, a circular conveying pipe 202, a discharge port 203, a spiral conveying shaft 204, and a discharge motor 205;

[0033] The U-shaped conveying pipe 201 is fixed in the middle of the two end plates 102 and distributed in the lower middle part of the horizontal cylinder 101. The circular conveying pipe 202 is fixed to the end face of one end plate 102, and the end plate 102 has a through hole that communicates with the U-shaped conveying pipe 201 and the circular conveying pipe 202.

[0034] The spiral conveyor shaft 204 is distributed inside the U-shaped conveyor pipe 201 and extends to the inside of the circular conveyor pipe 202. One end of the central shaft of the spiral conveyor shaft 204 is rotatably connected to the end plate 102 near the first parallel gear box 104, and the other end passes through the circular conveyor pipe 202 and is fixed to the output end of the discharge motor 205. The discharge motor 205 is installed at the outer end of the circular conveyor pipe 202.

[0035] The discharge port 203 is located at the bottom end of the circular conveying pipe 202;

[0036] The length of the U-shaped conveying pipe 201 is matched with the length of the horizontal cylinder 101. The screw conveying shaft 204 is driven by the discharge motor 205 to realize the complete discharge of materials inside the horizontal cylinder 101.

[0037] A valve assembly 3 is provided in the middle area between the horizontal cylinder 101 and the U-shaped conveying pipe 201. The valve assembly 3 is used to switch the U-shaped conveying pipe 201 and the horizontal cylinder 101 between the on and off states.

[0038] Valve assembly 3 includes an arc-shaped valve plate 301, a toothed roller 302, and a second parallel gearbox 303;

[0039] Two arc-shaped rotating grooves 105 are symmetrically opened at the bottom of the horizontal cylinder 101. The two arc-shaped rotating grooves 105 completely penetrate both sides of the U-shaped conveying pipe 201 to the inner cavity of the horizontal cylinder 101.

[0040] Two arc-shaped valve plates 301 are provided. The two arc-shaped valve plates 301 are slidably connected to the inner side of the two arc-shaped rotating grooves 105 respectively. The two arc-shaped valve plates 301 are attached to each other on the side closest to each other, which is used to form a distribution of the top opening of the U-shaped conveying pipe 201, thereby realizing the disconnection of the U-shaped conveying pipe 201 from the horizontal cylinder 101.

[0041] The two arc-shaped valve plates 301 extend to the outside of the U-shaped conveying pipe 201 on the side away from each other. The outer wall of the arc-shaped valve plate 301 is formed with toothed grooves. The toothed roller 302 is rotatably connected to the middle of the two end plates 102 and located below the arc-shaped valve plate 301. The toothed roller 302 matches the toothed grooves of the arc-shaped valve plate 301.

[0042] The rotating shafts of the two toothed rollers 302 extend to the outer end of the end plate 102 and are connected by a second parallel gearbox 303. The second parallel gearbox 303 is fixedly connected to the end plate 102 by a bracket. The two toothed rollers 302 are driven to rotate synchronously in opposite directions by the second parallel gearbox 303 to open the two toothed rollers 302 to each other, thereby realizing the connection between the U-shaped conveying pipe 201 and the horizontal cylinder 101.

[0043] In this embodiment, it should be noted that: a drive motor is installed at the output end of the first parallel gearbox 104 and the second parallel gearbox 303 respectively, and the first parallel gearbox 104 and the second parallel gearbox 303 have two output shafts, and the two output shafts rotate synchronously in opposite directions;

[0044] The operating principle of dry mortar mixing is as follows:

[0045] Dry mortar raw materials are added into the horizontal cylinder 101 through the top opening. During this process, the drive motor of the first parallel gearbox 104 is started simultaneously. The drive motor drives the two stirring paddles 103 to rotate synchronously and in opposite directions through the first parallel gearbox 104, so that the raw materials inside the horizontal cylinder 101 are circulated and stirred axially and radially, realizing efficient mixing of the raw materials. It should be noted that at this time, the two arc-shaped valve plates 301 are close to each other to disconnect the horizontal cylinder 101 from the U-shaped conveying pipe 201, so as to avoid the raw materials falling directly into the U-shaped conveying pipe 201 and causing insufficient mixing. At the same time, the inner wall of the arc-shaped valve plate 301 is slightly lower than the inner wall of the horizontal cylinder 101. This structure will result in some raw materials on the upper surface of the arc-shaped valve plate 301 not being easily scraped by the blades on the stirring paddle 103. However, when other raw materials move radially, they can be pushed by friction, thus ensuring the full mixing effect of the raw materials.

[0046] After the raw materials are mixed, the feeding operation can be carried out. At this time, the drive motor of the second parallel gearbox 303 and the discharge motor 205 are started simultaneously. The drive motor drives the two toothed rollers 302 to rotate synchronously in opposite directions through the second parallel gearbox 303. The two toothed rollers 302 push the two arc-shaped valve plates 301 away from each other, thereby opening the two arc-shaped valve plates 301. At this time, the horizontal cylinder 101 is connected to the U-shaped conveying pipe 201, and the material inside the horizontal cylinder 101 falls into the U-shaped conveying pipe 201. At the same time, the discharge motor 205 drives the spiral conveying shaft 204 to rotate. The spiral conveying shaft 204 conveys the material that falls into the U-shaped conveying pipe 201 to the circular conveying pipe 202, and finally discharges through the discharge port 203.

[0047] During the above process, the drive motor of the first parallel gearbox 104 continues to run. Thus, the rotation of the two stirring paddles 103 can scrape the material towards the middle of the horizontal cylinder 101 through the blades on their outer walls, allowing the material to enter the U-shaped conveying pipe 201 better. This not only makes the material unloading continuous and faster, but also effectively avoids the situation of material residue inside the horizontal cylinder 101.

[0048] Please refer to this carefully. Figures 3-4 Valve assembly 3 also includes an arc guide block 304;

[0049] The arc guide block 304 is symmetrically fixed at both ends of the arc-shaped valve plate 301, and a limiting arc groove 106 is provided at the position where the end plate 102 contacts the arc guide block 304;

[0050] The arc guide block 304 is slidably connected to the limiting arc groove 106, which is used to guide the movement trajectory of the arc-shaped valve plate 301 and limit the movement angle.

[0051] The thickness of the arc-shaped valve plate 301 matches the groove depth of the arc-shaped rotating groove 105. When the arc-shaped valve plate 301 is fully open, the side of the arc-shaped valve plate 301 closest to the U-shaped conveying pipe 201 is flush with the inner wall side of the U-shaped conveying pipe 201.

[0052] In this embodiment: during the rotation of the arc-shaped valve plate 301 to open or close, the arc guide block 304 rotates along the trajectory of the limiting arc groove 106, which not only makes the running trajectory of the arc-shaped valve plate 301 more stable, but also limits the closed position and open position of the arc-shaped valve plate 301.

[0053] Please refer to this carefully. Figures 1-2 The second parallel gearbox 303 and the first parallel gearbox 104 are located at the same end, and the circular conveying pipe 202 is located at the end away from the horizontal cylinder 101 and away from the first parallel gearbox 104 and the second parallel gearbox 303.

[0054] In this embodiment, this structure allows the material discharge to avoid the operating areas of the first parallel gearbox 104 and the second parallel gearbox 303, so that the two do not interfere with each other.

[0055] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
