Description

Technical Field

[0001] This utility model belongs to the field of construction machinery technology, and more specifically, it relates to a mortar mixer that is easy to maintain. Background Technology

[0002] Mortar is a binding material used in bricklaying in construction. It is made by mixing sand and cementing materials (cement, lime paste, clay, etc.) with water in a certain proportion. It is also called mortar. In the process of mortar processing, a mixer is often used for mixing. The mortar mixer is mainly used to mix various materials such as cement, sand, gravel, and water into a uniform mortar. Existing mortar mixers are mainly composed of a mixing system, a transmission system, a material conveying system, a control system, and a machine body structure.

[0003] The existing application number is CN202222942817.3. This utility model provides a mortar mixer, which relates to the technical field of mortar mixers. It includes a main body, a support frame fixedly installed at the lower end of the main body, a tray fixedly installed on the side of the support frame, a motor fixedly installed at the upper end of the tray, a positioning plate fixedly connected to the output end of the motor, a movable plate provided at the upper end of the positioning plate, a connecting column provided between the positioning plate and the movable plate, a stirring rod fixedly installed on the side of the connecting column, and a top cover provided at the upper end of the main body. At this time, the connecting column can be clamped between the movable plate and the positioning plate. After clamping, the through hole and the threaded hole are aligned. Then, by hand-tightening screws, it is convenient for people to fix the connecting column in the positioning plate and the movable plate, and then install the stirring rod. The connecting column can be pre-positioned using positioning pins and positioning holes. In this way, it is convenient for people to disassemble the stirring rod in the main body to clean the clumps on its surface.

[0004] Based on the above, in order to facilitate later maintenance, the existing mortar mixers generally have the mixing blades installed separately on the outside of the mixing shaft, which makes it easy to disassemble and maintain the mixing blades individually. However, when replacing the mixing blades, the installation position of the new mixing blades needs to be measured and positioned before installation, which affects the maintenance efficiency of the mortar mixer. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an easy-to-maintain mortar mixer. This solves the problem that existing mortar mixers, for ease of later maintenance, typically have their mixing blades installed separately on the outside of the mixing shaft. While this allows for easy disassembly and maintenance of the mixing blades, replacing them requires measuring and positioning the new blades before installation, which affects the efficiency of mortar mixer maintenance.

[0006] The purpose and effectiveness of this utility model, which provides an easy-to-maintain mortar mixer, are achieved through the following specific technical means:

[0007] An easy-to-maintain mortar mixer includes a mixer body, a mixing drive motor, a mixer cover, a mixing discharge plate, a stirring drive shaft, an opening and closing cleaning mechanism, and a maintenance auxiliary mechanism. The mixing drive motor is fixedly connected to the left side of the mixer body. The mixer cover is hinged to the top of the mixer body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model, through the setting of the opening and closing cleaning mechanism, rotates the mixer cover upward, and the rotating mixer cover pulls the cleaning transmission rod upward. The cleaning transmission rod drives the cleaning scraper to move upward, and the upward movement of the cleaning scraper achieves the cleaning of the inner wall of the mixer body, ensuring the cleanliness of the inner wall of the mixer body, making it convenient for maintenance personnel to observe the internal parts of the mixer body, and facilitating the maintenance operation of workers.

[0015] This utility model, through the setting of an auxiliary maintenance mechanism, facilitates the maintenance of the mixer body by disassembling and replacing the corresponding stirring blades. When it is necessary to add or remove stirring blades, rotating the maintenance operating lever drives the first drive gear, which in turn drives the second drive gear, which in turn drives the maintenance adjusting screw. The adjustment screw then moves the rightmost set of maintenance drive sliders to the left. This movement of the sliders moves the maintenance transmission component, which in turn moves the maintenance observation component. The movement of the observation component allows for adjustment of the installation spacing. Workers can then observe the position of the observation component through the observation window and install the stirring blades accordingly. This simplifies the replacement and installation of the stirring blades, eliminates the need for workers to measure the installation position, reduces operational steps, and improves the efficiency of maintaining the mixer body.
