Abstract
The utility model discloses a sand outlet adjusting device of a sand mixer, which is provided with an inner retainer ring and an outer retainer ring, wherein a rotary chassis connected with the sand mixer is arranged below the inner retainer ring and the outer retainer ring, an opening is arranged at one side of the outer retainer ring, and a sand hopper is arranged below one side of the rotary chassis at the position of the opening. The sand bucket has the advantages that after the guide plate is arranged, the defect that the quality of a sand mould is reduced or even the sand mould cannot be used due to sand bonding inside the sand bucket is effectively overcome, and meanwhile, the parking loss caused by sand bonding of the sand bucket during cleaning and accidents caused by sand cleaning are avoided. The production efficiency is improved by 5-8% according to 8 hours of work each day.
Description
Technical Field
The utility model belongs to a casting sand mixer, in particular to a sand outlet adjusting device of a sand mixer, which belongs to a casting sand mixer.
Background
For the casting sand mixer used at present, the mixed molding sand reaches a sand hopper through a sand mixer chassis, a sand outlet scraper and the like in the working process. Because structural design is unreasonable, the molding sand that mixes well can be washed and fall on the sand hopper lateral wall and form and pile up along the sand discharge scraper blade to sand hopper transportation in-process. This structure has the following disadvantages: the conveying efficiency of the molding sand is low; the longer time also reduces the overall performance of the molding sand resulting in quality problems and even scrap castings. The general solution is that the sand mixer is taken out for at least 30 minutes every shift and is stopped, the accumulation and the bonded sand of the molding sand in the hopper are cleaned manually, and due to the structural problem of the sand mixer, personal injury accidents caused by collision, slipping and the like sometimes occur during manual cleaning. To overcome this problem, the present inventors have earnestly studied to propose the object of the present invention.
Disclosure of Invention
The utility model aims to solve the problem caused by sand sticking in the sand mixer. Namely, the sand outlet adjusting device of the sand mixer is provided.
The technical scheme is that the sand outlet adjusting device of the sand mixer is provided with an inner retainer ring (13) and an outer retainer ring (12), a rotary chassis (11) connected with the sand mixer is arranged below the inner retainer ring and the outer retainer ring, an opening is formed in one side of the outer retainer ring, a sand hopper (2) is arranged below one side of the rotary chassis at the position of the opening, the sand outlet adjusting device is characterized in that an adjusting arm support (1) is fixed on the inner retainer ring (13), an adjusting arm (6) is assembled in the adjusting arm support, a fixed seat (3) is arranged on the outer retainer ring (12), the fixed seat is hinged with a sand outlet scraper (5) through a pin shaft I (4), the front part of the sand outlet scraper is hinged with the adjusting arm (6) through a pin shaft II (8), and a guide plate (7) is fixedly connected to one side, facing the sand hopper (2), of the side surface of the sand outlet scraper (5).
The beneficial technical effects of the utility model are as follows: after the guide plate is arranged, the defect that the quality of a sand mold is reduced or even the sand mold cannot be used due to sand bonding and sand collection inside the sand hopper is effectively overcome, and meanwhile, the parking loss caused by sand bonding of the sand hopper and the accident caused by sand cleaning are avoided. The production efficiency is improved, the sand mixing efficiency can be improved by 5 to 8 percent by recording 8 hours of the sand mixer working every day, and the casting quality can be improved by 3 to 5 percent

The numbers in the drawings are: 1. adjusting arm support, 2, sand hopper, 3, fixing base, 4, round pin axle I, 5, the sand discharge scraper blade, 6, adjusting arm, 7, guide plate, 8, round pin axle II, 9, outer scraper blade, 10, interior scraper blade, 11, gyration chassis, 12, outer retainer ring, 13, interior retaining ring.
Detailed Description
The details of the construction and use of the utility model are set forth in the accompanying drawings and the description below. Referring to the attached drawings, the sand outlet adjusting device of the sand mixer is provided with an inner retainer ring (13) and an outer retainer ring (12), a rotary chassis (11) connected with the sand mixer is arranged below the inner retainer ring and the outer retainer ring, an opening is formed in one side of the outer retainer ring, a sand hopper (2) is arranged below one side of the rotary chassis at the position of the opening, the sand outlet adjusting device is characterized in that an adjusting arm support (1) is fixed on the inner retainer ring (13), an adjusting arm (6) is assembled in the adjusting arm support, a fixing seat (3) is arranged on the outer retainer ring (12), the fixing seat is hinged with a sand outlet scraping plate (5) through a pin shaft I (4), the front part of the sand outlet scraping plate is hinged with the adjusting arm (6) through a pin shaft II (8), and a guide plate (7) is fixedly connected to one side, facing the sand hopper (2), of the side surface of the sand outlet scraping plate (5).
In order to increase the adjusting range of the sand outlet and adapt to the requirements of molding sand under different yield conditions, a group of adjusting holes (14) matched with the pin shaft II (8) are arranged on the adjusting arm (6). The angle between the scraping plate and the guide plate is adjusted, so that the sand outlet amount of the sand outlet can be adjusted.
In order to prevent the molding sand from being adhered to the inner retainer wall of the sand maker to generate new adhesion accumulation due to the change of the sand output amount of the molding sand after being adjusted by the adjusting arm, the sand outlet scraper (5) is structurally and innovatively designed, namely, the sand scraper is formed by combining an inner scraper (9) and an outer scraper (10), and the length of the outer scraper is longer than that of the inner scraper. By the structure, the automatic scraping of the new adhesive accumulated molding sand generated by adjusting the sand discharge amount on the inner retainer wall is realized.
The using process is as follows: the molding sand mixed by the sand mixer falls on a rotary chassis at the lower part of the sand mixer, and the molding sand is uniformly and continuously conveyed into a sand hopper of the sand mixer by a sand discharge scraper and a guide plate of the sand mixer fixed on the inner ring along with the rotation of the rotary chassis. Because the problem of adhesion and accumulation is not generated any more, the sand mixer can complete the continuous conveying work of the molding sand.
