Description

Technical Field

[0001] This utility model relates to the field of mortar treatment technology, and in particular to a dust-removing and environmentally friendly mortar mixing device. Background Technology

[0002] Mortar, as the most basic and widely used material in construction engineering, is a key source of dust pollution and material waste during its mixing process. With increasingly stringent environmental protection requirements and occupational health and safety standards for construction worldwide, traditional open-style, high-dust mixing methods can no longer meet the needs of modern construction.

[0003] In order to improve dust control and environmental protection, existing mortar mixing devices close the feed inlet with a baffle when the device is running to prevent dust from flying out. However, in order to improve work efficiency, workers may skip the step of closing the feed inlet with the baffle, which will cause dust to fly up during mortar mixing. To address this, we have developed a dust-control and environmentally friendly mortar mixing device. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a dust-removing and environmentally friendly mortar mixing device.

[0005] One of the objectives of this utility model is achieved through the following technical solution: A dust-removing and environmentally friendly mortar mixing device includes a mixing drum. A drive rod is rotatably connected to the top of the inner cavity of the mixing drum. A motor is installed at the top of the drive rod. Spiral blades and several stirring blades are fixedly connected to the outside of the drive rod. A feed funnel is fixedly inserted into the left side of the mixing drum near the top. A cover plate is provided on the top of the feed funnel. Connecting plates are fixedly connected to both the front and rear sides of the cover plate. A limit ring is fixedly connected to the bottom of the connecting plate. A limit rod is movably inserted through the inner cavity of the limit ring. A vertical plate is fixedly connected to the top of the cover plate near the right side. A first fixing block is fixedly connected to the right side of the vertical plate. A fixing box is fixedly connected to the top of the mixing drum near the left side. An insulating rod is movably inserted through the top of the fixing box. A compression spring is movably sleeved on the outside of the insulating rod. A second fixing block and a conductive block are fixedly connected to both ends of the insulating rod, respectively. Conductive plates are fixedly connected to both sides of the inner cavity of the fixing box.

[0006] Furthermore, four support legs are fixedly connected to the bottom of the mixing cylinder, and a solenoid valve is fixedly inserted into the bottom of the mixing cylinder.

[0007] Furthermore, a mounting plate is provided on the right side of the motor, and the motor is mounted on the mounting plate by screws. The mounting plate is fixedly connected to the top of the mixing drum, and the power output end of the motor is fixedly connected to the drive rod.

[0008] Furthermore, scrapers are provided on the left and right sides of the inner cavity of the mixing cylinder, and a first connecting rod and a second connecting rod are fixedly connected to the inner side of the scraper. The first connecting rod, the second connecting rod and the stirring blade are all fixedly connected to the drive rod.

[0009] Furthermore, the limiting rod is fixedly connected to the feed funnel, and the cross-section of the limiting rod is U-shaped.

[0010] Furthermore, the cross-sections of the first fixing block and the second fixing block are both right-angled trapezoids, the bottom of the second fixing block is fixedly connected to the top of the compression spring, and the bottom of the compression spring is fixedly connected to the top of the fixing box.

[0011] Furthermore, the conductive block is located inside the fixed box, and the two conductive plates are electrically connected to the positive terminal of the external power supply and the positive terminal of the motor, respectively, while the negative terminal of the motor is electrically connected to the negative terminal of the power supply.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model discloses a dust-removing and environmentally friendly mortar mixing device. The device is equipped with a fixed box, an insulating rod, a compression spring, a second fixed block, a conductive sheet, and a conductive block. When the device requires the motor to operate for mixing, the cover plate must be moved away from the second fixed block. The cover plate seals the opening of the feed funnel, preventing dust from flying out during mixing. The device links the movement of the cover plate with the starter motor, making it a mandatory operation. This prevents workers from forgetting to seal the opening of the feed funnel, thus improving environmental protection.

[0013] 2. This utility model provides a dust removal and environmentally friendly mortar mixing device. After the mixing is completed, the solenoid valve is opened to discharge the material. Then, the cover plate is pushed to the right. The cover plate presses the second fixed block through the first fixed block. The second fixed block drives the conductive block away from the conductive sheet through the insulating rod. The short circuit of the motor is broken and the motor stops working. This device can open the feeding funnel and stop the motor by moving the cover plate, achieving two goals at once.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0024] Working Principle: This utility model discloses a dust removal and environmentally friendly mortar mixing device. During use, mortar raw materials are poured into the mixing cylinder 1 through the feeding funnel 12.

The limiting ring 15 moves outside the limiting rod 16. The cover plate 13 seals the opening of the feeding funnel 12. The vertical plate 17 drives the first fixing block 18 away from the second fixing block 22. At this time, the second fixing block 22 moves upward under the elastic action of the compression spring 21. The second fixing block 22 drives the conductive block 24 to move through the insulating rod 20. The conductive block 24 moves between the two conductive plates 23.
