Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a stone removing device for reinforced concrete production. Background Art

[0002] Buildings are not just man-made products for people to stay, rest, and entertain themselves. They are closely related to our economy, culture, and life. The rapid development of the construction industry has also driven the development of the building materials industry, including the use of concrete. Concrete is generally made by mixing raw materials such as cement and gravel. After adding water and colloids, it can form a gel state and has a strong hardness after solidification. Concrete often contains some larger sand and gravel particles. These large particles will directly affect the use of concrete, and stone removal equipment is needed to treat them.

[0003] During use of the existing stone removal device, concrete is injected into the stone removal device through the feed port of the device, and the sand and concrete are separated by the filtering mechanism inside the device, thereby improving the quality of the concrete. However, the filtering mechanism is too simple to perform multi-stage screening of the concrete, resulting in the quality of the screened concrete not meeting the standards. Secondly, the filtering mechanism is prone to blockage during long-term use. If it is not cleaned in time, the effect of subsequent screening will be greatly reduced, reducing the practicability of the device. Therefore, we provide a stone removal device for reinforced concrete production. Utility Model Content

[0006] By adopting the above scheme, the threaded rod is driven to rotate by the servo motor. Since the thread on the surface of the threaded rod is matched with the thread on the inner wall of the threaded sleeve, when the servo motor rotates forward or reversely, the threaded sleeve can be driven to move left or right to realize reciprocating work. When the threaded rod rotates forward, the threaded sleeve is driven to move left by the threaded rod, the connecting column is driven to move left by the threaded sleeve, and the scraper is driven to move left by the connecting column, so that the sand and gravel particles on the No. 1 screen plate are scraped off and pushed to one side, so that the sand and gravel particles are transported to the bottom of the inner cavity of the screening box through the feed pipe and fall on the top of the No. 2 screen plate. The impact force generated when the sand and gravel particles fall can be used to drive the No. 2 screen plate to move downward, and the L-shaped connecting rod is driven downward by the No. 2 screen plate, and the spring is pressed down by the L-shaped connecting rod, so that the spring is deformed and vibrates, and the concrete inside the No. 2 screen plate is shaken off by the vibration.

[0009] As a preferred embodiment of a stone removal device for reinforced concrete production, one end of the threaded rod is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the shell.

[0010] By adopting the above scheme, one end of the threaded rod is limited and supported by setting the bearing, so as to prevent the threaded rod from being suspended in the air and then shaking.

[0011] As a preferred embodiment of a stone removal device for reinforced concrete production, a guide groove is provided in the inner cavity of the shell, a guide block is fixedly connected to the back of the threaded sleeve, and one end of the guide block is slidably connected to the inner wall of the guide groove.

[0012] By adopting the above scheme, the guide block is limited by setting the guide groove, and the threaded sleeve is assisted to move, thereby preventing the threaded sleeve from rotating.

[0013] As a preferred embodiment of a stone removal device for reinforced concrete production, a power supply box is fixedly connected to the back of the screening box and located below the shell, and a battery is provided in the inner cavity of the power supply box.

[0014] By adopting the above scheme, the electrical equipment is powered by the battery to maintain the normal operation of the electrical equipment.

[0015] As a preferred embodiment of a stone removal device for reinforced concrete production, a feed inlet is provided at the top of the screening box, and a discharge pipe is connected to the bottom of the screening box.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model drives the threaded rod to rotate through a servo motor. Since the threads on the surface of the threaded rod are matched with the threads on the inner wall of the threaded sleeve, when the servo motor rotates forward or reversely, the threaded sleeve can be driven to move left or right to realize reciprocating work. When the threaded rod rotates forward, the threaded sleeve is driven to move left through the threaded rod, the connecting column is driven to move left through the threaded sleeve, and the scraper is driven to move left through the connecting column, so that the sand and gravel particles on the No. 1 screen plate are scraped off, and the sand and gravel particles are transported to the bottom of the inner cavity of the screening box through the feed pipe, so as to achieve the purpose of self-cleaning and prevent blockage.

[0019] 2. The utility model utilizes the impact force generated when sand and gravel particles fall to drive the second screen plate to move downward, and drives the L-shaped connecting rod to move downward through the second screen plate, and presses the spring downward through the L-shaped connecting rod, so that the spring is deformed and vibrates, and the concrete inside the second screen plate is shaken off by the vibration. At the same time, the concrete can be filtered for the second time through the second screen plate, which greatly improves the quality of the screened concrete. BRIEF DESCRIPTION OF THE DRAWINGS
