The stroke set by the driving cylinder 3 during movement is greater than the parallel spacing between adjacent blades 5.
As shown in fig. 2, the bottom plate 1 is a rectangular iron plate, the width of which is slightly smaller than that of the belt conveyor support, and the tail part of which is provided with a notch. The two sides of the bottom plate 1 are provided with elongated guide rails 2, the middle of each guide rail 2 is provided with a guide groove 201, and the length of each guide groove 201 exceeds the gap at the tail part of the bottom plate 1.
As shown in fig. 3 and 5, the movable frame 4 is rectangular or square, has a number equal to or greater than one segment, and has the same structure, size and shape. Two ends of one frame of the movable frames 4 are provided with through holes 402 in an axisymmetric manner, the other frame is provided with a first pin hole 401, and the adjacent movable frames 4 are fixedly connected through the through holes 402 by bolts so as to meet different length requirements of the material cleaning scraper.
As shown in fig. 3, 4 and 5, 1 or more scrapers 5 are arranged in parallel and equidistantly in the movable frame 4, and the distance between the scrapers is smaller than the stroke of the reciprocating motion of the driving cylinder 3. The scraper 5 is a long-strip scraper, both ends of the scraper are respectively provided with an upper shaft 501, a lower shaft 502 and a cushion block 503 with the same width as the scraper 5, the scraper 5 and the cushion block 503 are fixedly connected through a bolt 12, and the head of the upper shaft 501 is inserted into the first pin hole 401, so that the scraper 5 has the function of swinging around the first pin hole 401. The tail of the upper shaft 501 is fixed on the upper side edge of the cushion block 503, the tail of the lower shaft 502 is fixed on the front surface of the cushion block 503 and is positioned above the bolt 12, the head of the lower shaft 502 is provided with threads, and the threads are screwed with the nut 11.
Fig. 6 is a partial enlarged view of a portion a in fig. 1, a second pin hole 801 is formed in the slider 8, a head portion of the lower shaft 502 penetrates through the second pin hole 801 formed in the slider 8, the slider 8 is located in the guide groove and reciprocates with the driving cylinder 3, a spring 10 is disposed between the slider 8 and the nut 11, a friction member 9 having an initial friction force is disposed on the slider 8, the friction member 9 having the initial friction force is pressed against surfaces of the guide rails 2 on both sides by the spring 10, and the pressing force is adjusted by the nut 11, so that the purpose of adjusting the frictional resistance between the friction member 9 having the initial friction force and the surfaces of the guide rails 2 is achieved.
The working principle is as follows:
when the driving cylinder 3 reciprocates, the lower shaft is temporarily stationary and does not move due to the frictional resistance generated by the friction member 9 having the initial frictional force, so that the driving cylinder 3 can drive the movable frame 4 to swing back and forth.
In the case of the forward movement of the scraper, as shown in fig. 6 and 7, the extension movement of the driving cylinder 3 in the direction of the arrow shown in the drawing is the movement when pushing out the material, and in the initial stage of pushing out the driving cylinder 3, the driving cylinder 3 extends forward to push the movable frame 4 forward, and since a large frictional resistance exists between the friction member 9 having the initial frictional force on the slider 8 and the surface of the guide rail 2, the slider 8 is kept temporarily stationary, and the lower shaft 502 on the scraper 5 inserted in the slider 8 cannot advance. At this time, however, the movable frame 4 drives the upper shaft 501 to rotate around the lower shaft 502 in the forward direction, and simultaneously drives the scraper 5 to rotate around the lower shaft 502 in the forward direction until the lower shaft 502 collides with the bottom of the frame of the movable frame 4. At this time, the squeegee 5 is kept in a relatively vertical state, and a small gap is kept between the lower edge of the squeegee 5 and the base plate 1. When the scraper 5 cannot rotate continuously due to the resistance of the movable frame 4, the driving cylinder 3 pushes the movable frame 4 to overcome the frictional resistance between the friction member 9 with initial friction and the surface of the guide rail 2, and drives the scraper 5 to scrape materials in a relatively vertical state.
When the scraping return motion is not performed, as shown in fig. 6 and 8, the contraction motion of the driving cylinder 3 in the arrow direction shown in the figure is the return motion of the non-scraping blade 5, and at the initial stage of the contraction of the driving cylinder 3, the driving cylinder 3 contracts and pulls the movable frame 4 backward, and since a large frictional resistance exists between the friction member 9 having the initial frictional force on the slider 8 and the surface of the guide rail 2, the slider 8 is kept temporarily stationary, and the lower shaft 502 inserted into the slider 8 cannot be retracted. At this time, the movable frame 4 drives the upper shaft 501 to rotate reversely around the lower shaft 502, the movable frame 4 drives the upper shaft 501 to retreat, that is, the upper shaft 501 drives the scraper 5 to rotate reversely around the lower shaft 502 until the lower shaft 502 collides with the bottom of the frame of the movable frame 4, at this time, the lower edge of the scraper 5 is close to the movable frame 4, and a large gap is kept between the lower edge of the scraper 5 and the bottom plate 1. When the scraper 5 cannot rotate any more, the driving cylinder 3 pulls the movable frame 4 to overcome the frictional resistance between the friction member 9 having the initial frictional force and the guide rail 2, and the scraper 5 is driven to remain returned.
When the driving cylinder 3 continuously reciprocates, the movable frame 4 drives the scraper 5 to follow the reciprocating motion. Since the stroke set by the driving cylinder 3 during movement is greater than the parallel distance between the scrapers 5. The material falling into the reciprocating type material cleaning scraper is intermittently pushed out, so that the purpose of cleaning the material is achieved.
Fig. 9 is an improvement made on the basis of the first embodiment, in which the driving cylinders 3 are double cylinders and are respectively fixed on two sides of the bottom plate 1, and the fixing manner of the two ends of the driving cylinders is the same as that of the embodiment 1 as that of the bottom plate 1 and the movable frame 4, although the driving cylinders 3 may be three or more cylinders, which is not described again in this embodiment.
The utility model discloses be not limited to above-mentioned embodiment, for example: the main drive is changed from a driving cylinder 3 to a crank block device to do reciprocating motion; the shape of the movable frame is changed into a square shape; the mode of adjusting the frictional resistance by the spring 10 is changed into a mode of pressing the sliding block 8 by gravity; change the connection between the movable frames to a hinge connection, etc. All technical solutions formed by equivalent substitutions fall within the protection scope of the present invention.
