When the concrete body passes by, the multiple second pre-cutting knives 15 make horizontal cuts on the left and right sides of the concrete body.

[0059] The upper end of the second pre-cutter seat 14 is fixed on the first gantry 11, and a plurality of mounting holes 16 are arranged on the second pre-cutter seat 14, and the plurality of mounting holes 16 are evenly distributed on the second pre-cutter seat 14 from bottom to top; the second pre-cutter 15 is detachably fixed in the mounting hole 16. When the thickness of the concrete blocks is different, the position of the second pre-cutter 15 on the second pre-cutter seat 14 can be adjusted up and down.

[0060] The first gantry 11 is also provided with a blank forming and cutting assembly, which is located on the downstream side of the pre-cutting assembly. The blank forming and cutting assembly includes an upper cutting wire 15 and two side cutting wires 18 and 19. The upper cutting wire 15 is located directly above the conveying track 5, crosses the conveying track 5 and is fixed on the first gantry 11.

[0061] The first gantry 11 is also provided with a scraper assembly, which is located downstream of the blank forming and cutting assembly. The scraper assembly includes an upper scraper 17 and two side scrapers 110. The upper scraper 17 is located on the downstream side of the upper cutting wire 15 and is fixedly mounted on the first gantry 11. The two side scrapers 110 are located on both sides of the conveying track 5 and the side scrapers 110 are adjustably mounted on the first gantry 111. Specifically, the side scraper 110 includes a scraper bracket fixedly connected to the first gantry 11, and a plurality of bolt holes are arranged on the scraper bracket.

Optimally, the side scraper 110 is arranged obliquely and its upper end is located on the downstream side of the lower end.

[0062] like Figure 2 and Figure 3As shown, the vertical cutting device 2 includes a second gantry 21, on which a vertical cutting assembly 22 is provided. The vertical cutting assembly 22 adopts a cutting device in the prior art, which will not be described in detail. A cleaning assembly 23 is provided on the downstream side of the vertical cutting assembly, and the cleaning assembly 23 includes a fixed bracket 24, an adjustment bracket and a brush assembly 27. The fixed bracket 24 is fixed on the second gantry 21 and extends to the downstream side of the second gantry 21; the adjustment bracket includes a mounting plate 25 fixed to the fixed bracket 24, and two stud mounting holes are provided on the mounting plate 25. Studs 26 are provided in the stud mounting holes, and the upper ends of the studs 26 are fixed to the mounting plate 25 by two locking nuts; the brush assembly 27 is fixed to the lower end of the stud 25. A brush assembly 27 is provided at the lower end of the adjusting stud 26. Due to the obstruction of the brush assembly 27, material accumulation is formed on the upstream side of the brush assembly 27. Excessive material accumulation may cause damage to the cutting wire of the vertical cutting assembly 22. In order to avoid this problem, an anti-material accumulation space is reserved between the brush assembly 27 and the vertical cutting device 22.

[0063] like Figure 4 As shown, the brush assembly 27 includes a base plate fixed on the adjustment stud 26, and the base plate includes a first fixing plate 29 and a second fixing plate 28, and the second fixing plate 28 is fixedly connected to the adjustment stud 26. The first fixing plate 29 and the second fixing plate 28 are connected in a V shape and the first fixing plate 29 and the second fixing plate 28 are formed by bending a spring steel plate at one time; the spring steel plate has good elastic deformation, so the first fixing plate 29 is allowed to rotate relative to the bending part. The first fixing plate 29 is located on the upstream side of the second fixing plate 28, and a plurality of brushes 210 are fixed on the first fixing plate 29 and the second fixing plate 28 respectively.

[0064] When there is less waste on the concrete body, the force exerted on the first fixed plate 29 is small, the first fixed plate 29 and the second fixed plate 28 are separated, and the brushes 210 on the first fixed plate 29 and the second fixed plate 28 respectively form two cleaning lines, which can ensure the cleaning effect; if there is more waste on the concrete body, the waste is easy to accumulate at the brush 210 on the first fixed plate 29 and exert a larger force on the first fixed plate 29, which pushes the first fixed plate 29 to rotate toward the second fixed plate 28 so that the first fixed plate 29 and the second fixed plate 28 fit together, and the two layers of brushes 210 are combined to form a wider cleaning belt, which can effectively avoid waste retention. Optimally, the second fixed plate 28 is perpendicular to the conveying direction of the concrete body. The angle between the first fixed plate 29 and the second fixed plate 28 is less than 30°. If the angle is too large, it is easy to cause the first fixed plate 29 and the second fixed plate 28 to fit poorly.

[0065] It also includes a brush locking plate 211, which is U-shaped, and the brush 210 is located in the recessed portion of the brush locking plate 211; the recessed portion and the first fixed plate 29 or the second fixed plate 28 form a locking cavity for accommodating the brush 210, and the two ends of the brush locking plate 211 can fit more closely to the first fixed plate 29 or the second fixed plate 28, thereby forming a space for accommodating the bolt head, and the brush locking plate 211 is fixedly connected to the first fixed plate 29 or the second fixed plate 28 by a bolt and nut combination.

Preferably, the first spring sheet group 6 is located at the upper end of the rubber pad 51, and the second spring sheet group 7 is located at the lower end of the rubber pad 51. The first spring sheet group 36 and the second spring sheet group 37 each include a plurality of spring sheets 38, one side of the spring sheet 38 is connected to the rubber pad 351, and the other side extends obliquely toward the center of the rubber pad 351. The spring sheet 38 forms an angle of less than 15° with the surface of the rubber pad 351, and the spring sheet 38 and the rubber pad 351 are integral, such as Figure 8 and Fig. 9 As shown, the spring sheet structure is directly cut out during the processing of the rubber pad 351; or, the spring sheet 38 is a V-shaped metal sheet with one end inserted into the rubber pad 351, such as Fig.10 As shown, the spring piece 38 is a V-shaped metal spring piece, and one of the outwardly extending arms of the spring piece 38 is inserted into the hole of the rubber pad 51 .

[0069] An angle less than 15° is formed between the spring piece 38 and the surface of the rubber pad 351. Under the support of the spring piece 38, a buffer space is formed between the plastic film 352 and the rubber pad 351, which can buffer the impact between the concrete body and the support plate 353, and also avoid the problem of the concrete body and the rubber pad 351 adhering to each other, causing the surface quality of the concrete body to deteriorate.
