The purpose of stress balance is achieved.
Description
Technical Field
The invention relates to the field of construction machinery, in particular to a stirring machine scraping device and a stirring machine.
Background
The effect of the scraping arm of the stirrer is as follows: firstly, materials adhered to or close to the edge of the cylinder wall are scraped to the middle part to participate in stirring during stirring, so that the stirring quality is improved; secondly, after the stirring, scrape the material to the discharge gate through the scraper blade, avoid section of thick bamboo wall and section of thick bamboo bottom bonding clout. The current scraping arms on the market adopt a vertical wall, and as shown in figure 1, after the scraping arms extend to the edge of a cylinder body, a scraping plate is arranged at the downward vertical part. After the blade has been in use for some time, it is necessary to make occasional adjustments to the blade due to wear. The prior scraping arm structure has the following problems:
1. the stress is unbalanced. The scraper blade is used for scraping the materials on the side wall and the cylinder bottom, the stress point is mainly at the lower part, and the materials stuck on the side wall and the materials piled on the cylinder bottom are not uniform. On one hand, uneven stress on the upper part and the lower part of the scraper can be caused by the upper part of the supporting point, and the wear on the upper part and the lower part of the scraper is inconsistent due to long-time use; on the other hand, the scraping arm belongs to a cantilever structure, and due to the fact that the diameter of the cylinder body is large, materials on the wall of the cylinder are required to be scraped, the scraping arm needs to be large, and therefore the reaction force in the stirring process can be borne by the larger cross section.
2. The adjustment is inconvenient. After the scraper blade wearing and tearing certain degree, in order to make the scraper blade keep good effect, need adjust earlier and scrape the arm and make it be close to the lateral wall more, adjust the scraper blade again and make its bottom be close to the barrel head more, consequently adjust very inconveniently.
Disclosure of Invention
The invention aims to provide a stirring machine scraping device, which achieves the aim of balancing stress.
The technical purpose of the invention is realized by the following technical scheme: a scraping device of a stirrer comprises a scraping arm and a scraping plate, wherein the scraping arm comprises an assembling part, a connecting part and an installing part; one end of the connecting part is connected with the assembling part, and the other end of the connecting part is connected with the mounting part; the assembling part is connected with the revolution part of the stirrer; the scraper is arranged on the mounting part; the scraping arm is obliquely arranged downwards along the assembling part and the connecting part.
The scraping arm horizontally arranged in the prior art is changed into the inclined downward arrangement, so that the connecting point of the scraping arm and the scraping plate is closer to the stress point of the scraping plate, and the moment is reduced. On one hand, the stress of each point of the scraper is more balanced, and on the other hand, the cross-sectional area of the scraping arm can be reduced under the same stress condition, so that the material is saved, and the overhauling difficulty is reduced.
Furthermore, a mounting plate is arranged on the revolution part of the stirrer; the assembling part is arranged on the revolution part in a matching way through the pressing plate and the mounting plate; the mounting plate is obliquely arranged; the inclination angle of the mounting plate is adapted to the scraping arm.
Typically, a blender paddle revolves around the blender axis while rotating around itself. And thus has a revolving component. The scraping arm is arranged on the revolution part, so that the materials at the edge of the mixing drum can be effectively scraped. The assembly part is arranged on the revolution part through the matching of the pressing plate and the mounting plate, when the pressing plate is loosened, the assembly part is loosened, the position of the scraping arm can be adjusted, and then the distance from the scraping plate to the cylinder wall and the cylinder bottom is adjusted. Compared with the prior art that the horizontal distance of the scraping arm and the vertical distance of the scraping plate need to be adjusted simultaneously, the same effect can be achieved only by adjusting the position of the scraping arm, the operation is simpler, and the overhauling and maintenance are more convenient.
Furthermore, grooves are formed in the mounting plate and the pressing plate; the groove is adapted to the fitting portion.
The groove which is matched with the assembling part is arranged, so that the scraping arm can be more effectively fixed when the scraping arm is used, the rotating trend of the scraping arm is offset, and the moving position of the scraping arm is prevented.
Furthermore, the included angle between the mounting part and the connecting part is 100-170 degrees; a backing plate is arranged on the mounting part; the scraper blade sets up on the backing plate.
The installation part and the connecting part are provided with included angles which are matched with the inclination angle of the scraper blade, so that the base plate can be more conveniently installed. Meanwhile, the transmission of force is facilitated during working, and unbalanced stress of the upper part and the lower part of the scraper is avoided.
Further, the backing plate comprises a first backing plate and a second backing plate; the scraping plate is provided with a scraping wall part and a scraping bottom part; the first base plate is connected with the wall scraping part; the second backing plate is connected with the scraping bottom.
The scraper and the base plate are divided into two parts, so that materials on the cylinder wall and the cylinder bottom can be scraped more effectively.
Further, the cross section of the wall scraping part is C-shaped.
Through the scraper blade of "C" shape, can carry out water conservancy diversion effectively to being close to section of thick bamboo wall material, make the material flow to the mixer middle part more easily.
Furthermore, the included angle between the extending direction of the scraping bottom and the tangential direction of the rotating scraping bottom is more than or equal to 90 degrees.
Through adopting above-mentioned scheme, can carry out the water conservancy diversion to the material that is close to the barrel head better, make its flow direction mixer middle part participate in the stirring.
The invention also provides a stirrer which is provided with any one stirrer scraping device.
In summary, the invention has at least one of the following advantages:
1. the scraping arm is obliquely arranged, so that the stressed moment of the scraping arm is reduced, and the stress conditions of the scraping arm and the scraping plate can be improved; the same effect can be achieved by adopting the scraping arm with a smaller cross section, so that the material is saved, and the cost is reduced.
2. When the scraper is worn, the distance from the scraper to the cylinder wall and the cylinder bottom can be adjusted only by adjusting the length of the scraping arm, so that the maintenance time is shortened, and the cost is saved.
In the invention, the inclination angle of the scraping arm is determined according to the diameter of the stirring barrel and the height of the installation position of the scraping arm. Generally, the scraping arm and the cylinder bottom form an included angle of 10-80 degrees.
