Description

Sand mixer

Technical field

The utility model relates to a kind of sand mixers, belong to machinery field.

Background technique

Sand mixer is using relative motion between rolling wheel and cylinder, by the intracorporal material of cylinder by rolling the work for having both grinding With and comminuting matter, sand mixer also have the function of stirring while rolling material so that material mixes, but rolling wheel is rolled When material, partial material can be sticked on rolling wheel, and existing method is to scrape rolling wheel by the way that relatively-stationary scraping blade is arranged, from And make the feed separation on rolling wheel, in order to guarantee by rolling wheel material scraping lose no time, it is desirable to scraping blade completely with rolling The application of a surface of wheel, and if scraping blade installation inclination, the material on a part of rolling wheel is struck off with regard to intelligence, it can not be by the object on rolling wheel Material strikes off completely, in addition, after using one end time, scraping blade will appear even if scraping blade is bonded with the curved surface of rolling wheel completely completely Certain abrasion also will appear the case where can not removing material on rolling wheel.

Utility model content

Of the existing technology in order to solve the problems, such as, the utility model provides a kind of sand mixer, can be automatically by rolling wheel On material strike off.

The technology employed by the present utility model is

A kind of sand mixer, including cylinder, the center of the cylinder are provided with shaft, and the bottom of the cylinder is provided with The driving device of the shaft rotation is driven, mounting rack is provided in the shaft, rolling wheel there are two settings on the mounting rack, Be provided with wiper blade holder on the mounting rack, the quantity of the wiper blade holder is 2, two wiper blade holders with described in two Rolling wheel corresponds, and scraping blade is provided in the wiper blade holder, and the scraping blade is fixed on the corresponding scraping blade branch by spring On frame, the free end of the scraping blade is fitted on the curved surface of the corresponding rolling wheel.

In general, the scraping blade includes multiple fragments, multiple fragments are uniformly distributed along the wiper blade holder, Mei Gesuo It states fragment and passes through the spring and be mounted in the wiper blade holder.

Further, spaced between two adjacent fragments, the width of the fragment is greater than the interval Width.

Preferably, the wiper blade holder scrapes horse including two, and horse is scraped described in two before and after the corresponding rolling wheel Setting, the fragment be mounted on it is described scrape on horse, it is respectively first to scrape horse and second and scrape horse that horse is scraped described in two, institute It states the fragment that first scrapes on horse and scrapes the fragment on horse with described second and mutually stagger.

Preferably, if described scrape is equipped with dry slide in horse, the quantity of the slideway is equal with the quantity of the fragment, if It does the slideway to be arranged side by side, through the outer wall for scraping horse, the free end of the fragment passes through institute for one end of the slideway One end of slideway is stated, the rear side of the fragment is connect with one end of the spring, and the other end of the spring is fixed on the cunning On the other end in road.

Further, limit film is fixed on rear side of the fragment, the two sides of one end of the slideway are respectively equipped with block, There are gap, the fragment and the clearance sliding fit between two blocks, the size of the limit film is greater than described The size in gap.

The utility model has the beneficial effects that

The utility model is withstood on scraping blade on the curved surface of rolling wheel by spring, thus the material on the rolling wheel rotated can be scraped Piece strikes off, thus the free end of scraping blade occur abrasion after, spring also can withstand outward scraping blade, guarantee scraping blade still with rolling wheel Application of a surface, it is ensured that the material on rolling wheel is struck off.

Specific embodiment

Referring to figures 1-4, the utility model provides a kind of sand mixer, including cylinder 1, the center of the cylinder 1 It is provided with shaft, the bottom of the cylinder 1 is provided with the driving device for driving the shaft rotation, is provided with peace in the shaft It shelves, rolling wheel 2 there are two settings on the mounting rack, is provided with wiper blade holder, the number of the wiper blade holder on the mounting rack Amount is 2, and two wiper blade holders are corresponded with two rolling wheels 2, are provided with scraping blade in the wiper blade holder, described Scraping blade is fixed in the corresponding wiper blade holder by spring 6, and the free end of the scraping blade is fitted in the corresponding rolling wheel 2 Curved surface on.

Certain material is shelved in cylinder 1, driving device drives shaft rotation, and the shaft of rotation drives two rolling wheels 2 It is rotated around shaft, since rolling wheel 2 is vertically arranged, thus rolling wheel 2 can rotate walking on cylinder 1, roll material to play Purpose, while having both the function of stirring material, since rolling wheel 2 rolls material so that material sticks on the curved surface of rolling wheel 2, The application of a surface of scraping blade in wiper blade holder and rolling wheel 2 at this time, can be by under the material scraper on rolling wheel 2, since scraping blade passes through bullet Spring 6 is mounted in wiper blade holder, thus spring 6 can always push up scraping blade always outward, so that the free end of scraping blade is located always In on the curved surface for being fitted in rolling wheel 2, even if after abrasion occurs in scraping blade, it is also possible that the free end of scraping blade is fitted in rolling wheel 2 Curved surface on.

The scraping blade includes multiple fragments 5, and multiple fragments 5 are uniformly distributed along the wiper blade holder, each described Fragment 5 is mounted in the wiper blade holder by a spring 6.

Scraping blade is divided into multiple fragments 5, thus when scraping blade is equipped with some deflections, each fragment 5 is pushed up by spring 6 On the curved surface of rolling wheel 2, and the limited length of each fragment 5, thus opposite can guarantee that each scraping blade can be by its corresponding rolling 2 curved surfaces are taken turns to be bonded.

Spaced between the fragment 5 of adjacent two, the width of the fragment 5 is greater than the width at the interval.

The setting at interval is prevented from interfering when two adjacent 5 fore-aft motions of fragment, be prolonged its service life.

The wiper blade holder includes two and scrapes horse, and horse is scraped described in two and is arranged before and after the corresponding rolling wheel 2, institute State fragment 5 be mounted on it is described scrape on horse, it is respectively first to scrape horse 3 and second and scrape horse 4 that horse is scraped described in two, described the One, which scrapes the fragment 5 that the fragment 5 on horse 3 is scraped with described second on horse 4, mutually staggers.

The first corresponding partial material in interval scraped on the scraping blade on horse 3 can not be removed effectively, and second scrapes horse 4 On the fragment 5 scraped with first on horse 3 of fragment 5 be staggered, thus the material of compartment can be removed.

If described scrape is equipped with dry slide in horse, the quantity of the slideway is equal with the quantity of the fragment 5, several described Slideway is arranged side by side, and through the outer wall for scraping horse, the free end of the fragment 5 passes through the slideway for one end of the slideway One end, the rear side of the fragment 5 connect with one end of the spring 6, and the other end of the spring 6 is fixed on the slideway On the other end.

The rear side of the fragment 5 is fixed with limit film 7, and the two sides of one end of the slideway are respectively equipped with block, two institutes It states there are gap, the fragment 5 and the clearance sliding fit between block, the size of the limit film 7 is greater than the gap Size.
