It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. Dry-mixed mortar plays a bonding, cushioning, protective and decorative role in the construction industry with a thin layer. It is widely used in construction and decoration projects. Dry-mixed mortar needs to mix multiple raw materials during processing to ensure subsequent normal use. The mixing and conveying device can quickly and evenly mix multiple raw materials and output the mixed raw materials to improve processing efficiency. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN212218877U discloses a material mixing and conveying device for dry-mixed floor mortar, wherein the first feeding box, the second feeding box and the third feeding box are all provided with weight sensors at the bottom, the first feeding box, the second feeding box and the third feeding box are all located above the preliminary mixing tank, the first feeding box is connected with the preliminary mixing tank through a first connecting pipe, and the material mixing and conveying device can weigh a variety of materials, so that the materials are mixed according to an accurate ratio to ensure the quality of the dry-mixed mortar, but in actual use, the staff is required to pour the materials into the feeding box, and then weigh them, and then add another material when the specified amount is reached, which is inconvenient to operate;

[0004] When materials are fed and discharged, the distance between the feeding position and the discharging position is often far, and the device needs to transport the mixed materials through a conveying structure, which makes the device larger and inconvenient for spatial layout. Although the mobile mixing and conveying device is small in size and convenient for transporting dry-mixed mortar, it has a simple structure and the feeding and discharging operations are relatively inconvenient. Utility Model Content

[0005] The utility model aims to provide a dry-mix mortar mixing and conveying device, which solves the problems that the addition and weighing of multiple materials are inconvenient during actual use of the dry-mix mortar mixing and conveying device through a mixing barrel, a conveying pipe and a mobile base, the device that can directly convey materials over long distances is large in size, and the mobile device has a simple structure and inconvenient material loading and unloading operations.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a dry-mix mortar mixing and conveying device, comprising a mixing barrel, a feeding pipe and a movable base, wherein a maintenance cover is fixedly connected to the top of the mixing barrel, a stirring motor is fixedly connected to the top of the maintenance cover, a feeding pipe is welded through the bottom of the mixing barrel, a plurality of feeding pipes are arranged on the outer peripheral surface of the feeding pipe, a feeding rod is fixedly connected to the top of each of the feeding pipes, a movable base is arranged at the bottom of the feeding pipe and the plurality of feeding pipes, a plurality of weighing support plates are arranged on the top of the movable base, and the plurality of feeding pipes are respectively suspended on the top of the plurality of weighing support plates;

[0008] The stirring motor can drive the stirring blades to rotate, stir the materials at high speed, make the materials mixed evenly, and prevent the materials from being discharged through the feeding pipe when the materials are fed and stirred. After the materials are mixed evenly, the stirring motor drives the first spiral feeding assembly to rotate in the opposite direction, which can drive the stirred dry mixed mortar to be discharged quickly, thereby improving the automation degree of the device. When feeding multiple materials, the storage structure of multiple materials is placed on the top of multiple weighing support plates. A pressure sensor assembly is arranged in the weighing support plate, which can weigh the materials. The rotation of the feeding rod drives the first spiral feeding assembly to rotate in the opposite direction, which can drive the stirred dry mixed mortar to be discharged quickly, thereby improving the automation degree of the device. The two-screw feeding assembly rotates to allow the material in the storage structure to enter the mixing barrel for stirring through the feeding pipe and the feeding pipe. When the input of one material is close to the specified amount, the corresponding weighing support plate drives the storage structure downward to stop feeding the corresponding material. The staff does not need to manually add and weigh the materials, and can add and weigh multiple materials simultaneously to ensure the accuracy of the material ratio, which improves the convenience of using the device. The device can be moved by the mobile base, so that the device can feed and mix materials while moving to the discharge position, thereby improving the processing efficiency of dry mixed mortar.

[0009] Furthermore, a support frame is welded and fixed to the bottom edge of the mixing barrel, the support frame is clamped and fixed to the top of the mobile base, and a water inlet pipe is welded through one end of the top of the maintenance cover;

[0010] When there is no need to pour water, the water inlet pipe can prevent the air pressure in the mixing barrel from being too high, which makes it difficult to feed the materials quickly. After multiple materials enter the mixing barrel, an appropriate amount of water can be poured into the mixing barrel through the water inlet pipe to fully mix the water and materials.

[0011] Furthermore, a support rod is rotatably connected to the bottom of the stirring motor, and a stirring blade and a first spiral feeding component are fixed to the outer peripheral surface of the support rod from top to bottom, the support rod is inserted through the top of the maintenance cover, one end of the stirring blade is attached to the inner wall of the mixing barrel, and the first spiral feeding component and the bottom of the support rod are inserted into the inner side of the feeding pipe;

[0012] The stirring motor can drive the support rod to rotate, and further drive the stirring blades and the first spiral feed assembly to rotate, so that the material entering the feed pipe through the feed pipe can further enter the mixing barrel through the feed pipe, and the various raw materials can be mixed and stirred by the rotation of the stirring blades. After the materials are evenly mixed, the stirring motor drives the first spiral feed assembly to rotate in the opposite direction, which can drive the stirred dry mixed mortar to be quickly discharged, thereby improving the degree of automation of the device and the convenience of operation.

[0013] Furthermore, a connecting tube is welded through the top of the outer circumference of each feed pipe, and the other end of each connecting tube is inserted through and clamped on the outer circumference of the feed pipe, a feed motor is clamped on the top of one feed pipe, and a feed rod is clamped on the bottom of the feed motor, and a transmission belt is rotatably clamped on the outer circumference of every two adjacent feed rods, and a second spiral feed assembly is welded and fixed on the outer circumference of each feed rod, and each of the second spiral feed assemblies is respectively inserted through and plugged into the bottom of each feed pipe;

[0014] The feeding motor drives a feeding rod to rotate, and drives multiple feeding rods to rotate through multiple transmission belts, so that the materials placed in the storage structure can quickly enter the feeding pipe, without the need for manual feeding, thereby improving the convenience of using the device.

[0015] Furthermore, a telescopic rod is clamped at the bottom of each weighing support plate, a lifting cylinder is slidably clamped at the bottom of each telescopic rod, each lifting cylinder is clamped at the inner side of the mobile base, and each telescopic rod is inserted through the top of the mobile base;

[0016] When the material is fed, the storage structure of the material is placed on the top of multiple weighing support plates, and the remaining amount of the material is weighed by the weighing support plates. The storage structure is driven to rise and fall by the lifting cylinder so that the feeding pipe can be inserted into the material. The material in the storage structure enters the mixing barrel through the feeding pipe and the delivery pipe for stirring. When the input of one material is close to the specified amount, the corresponding weighing support plate drives the storage structure downward to stop feeding the corresponding material. The staff does not need to manually add and weigh the materials, and can add and weigh multiple materials simultaneously to ensure accurate material ratios and improve the convenience of using the device.

[0017] Furthermore, flow guide frames are rotatably connected to both sides of the top of the mobile base, a counterweight assembly is fixedly connected to the center of the bottom of the mobile base, and universal wheels are rotatably connected to the four sides of the bottom of the mobile base;

[0018] The guide frame can be used to facilitate the transportation of the material storage structure to the upper side of the mobile base, and when the device is not in use, the guide frame can be rotated upward and retracted. The counterweight assembly can improve the stability of the device during transportation and use. The universal wheel can drive the device to move, so that the device can feed and mix materials while moving to the discharge position, thereby improving the processing efficiency of dry-mixed mortar.

[0019] The utility model has the following beneficial effects:

[0020] The utility model solves the problem that the material mixing and conveying device can weigh multiple materials by arranging a feeding pipe and a movable base, so that the materials are mixed according to the accurate proportion and the quality of the dry mixed mortar is guaranteed. However, in actual use, the staff is required to pour the materials into the feeding box and then weigh them. When the specified amount is reached, another material is added, which is inconvenient to operate. When feeding multiple materials, the material storage structure is placed on the top of multiple weighing support plates, and the remaining amount of the material is weighed by the weighing support plates. The feeding motor drives the feeding rod and the second spiral feeding assembly to rotate, so that the material in the storage structure enters the mixing barrel through the feeding pipe and the feeding pipe for stirring. When the input of one material is close to the specified amount, the corresponding weighing support plate drives the storage structure downward to stop feeding the corresponding material. The staff does not need to manually add and weigh the materials, and multiple materials can be added and weighed simultaneously, which ensures the accurate material ratio and improves the convenience of using the device.

[0021] The utility model solves the problem that when materials are fed and discharged, the feeding position and the discharging position are often far apart, and the device needs to transport the mixed materials through the conveying structure, which leads to a large size of the device and is not convenient for spatial layout. Although the mobile mixing and conveying device is small in size and convenient for transporting dry mixed mortar, it has a simple structure and is inconvenient for feeding and discharging operations. When mixing and conveying the dry mixed mortar, the storage structure is placed on top of multiple weighing support plates, and the feeding motor is controlled to drive the feeding rod and the second spiral feeding assembly to rotate to feed a variety of materials, and the stirring motor drives the materials entering the mixing barrel to be stirred while the mobile base drives the device and the materials to move. After reaching the specified position and mixing the raw materials evenly, the stirring motor drives the first spiral feeding assembly to rotate in the opposite direction, so that the dry mixed mortar in the mixing barrel can be quickly discharged through the feeding pipe under the push of gravity and the first spiral feeding assembly. The operation is simple and convenient, and the processing efficiency of the dry mixed mortar is improved. BRIEF DESCRIPTION OF THE DRAWINGS
