Existing sand making devices mostly use mechanical power control to operate, and crush the stone through a crusher or a crushing roller. However, in the actual operation process, the particle size of the produced sand is difficult to adjust quickly. At the same time, after the discharge is completed, the operator needs to screen the sand, which increases the overall sand making time and reduces the efficiency.

[0003] Therefore for the above problems now develop a kind of sand making device of building construction. Utility Model Content

[0004] In order to overcome the shortcomings of the existing device in the specific operation process, that the particle size of the produced sand material is difficult to be quickly adjusted, and the operator needs to screen the sand material after the discharge is completed, which leads to an increase in the overall sand making time and a decrease in efficiency, the utility model provides a sand making device for construction construction.

[0005] The technical solution of the utility model is: a sand making device for construction, comprising a base, a trapezoidal material pouring table is installed inside the base, a double-axis motor is installed on the outer side of the front of the base, first bevel gears are arranged on the left and right output shafts of the double-axis motor, the first bevel gear on the left is slidably connected to the left output shaft of the double-axis motor, two crushing rollers are rotatably arranged inside the base, the front of the crushing rollers are connected to second bevel gears, the first bevel gears are meshed with the adjacent second bevel gears, a hydraulic push rod is installed on the upper left side of the front of the base, a sleeve frame is slidably provided at the bottom of the telescopic end of the hydraulic push rod, the sleeve frame is rotatably connected to the first bevel gear on the left and the crushing roller on the left, the sleeve frame is slidably connected to the left output shaft of the double-axis motor, an auxiliary screening mechanism is provided at the lower part of the base, and a scraping mechanism is provided inside the base.

DETAILED DESCRIPTION

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] A sand making device for building construction, such as Figure 1-Figure 3 As shown, it includes a base 1, a trapezoidal material unloading platform is installed inside the base 1, and the four sides of the trapezoidal material unloading platform are all inclined structures. A triangular rib frame is arranged at the bottom of the base 1, and a double-axis motor 2 is installed on the outer side of the front of the base 1. The left and right output shafts of the double-axis motor 2 are provided with first bevel gears 3, and the first bevel gear 3 on the left is slidably connected with the left output shaft of the double-axis motor 2. Two crushing rollers 5 are rotatably arranged inside the base 1, and the front of the crushing rollers 5 are connected with second bevel gears 4. The first bevel gears 3 are meshed with the adjacent second bevel gears 4. A hydraulic push rod 7 is installed on the upper left side of the front of the base 1, and a sleeve frame 6 is slidably provided at the bottom of the telescopic end of the hydraulic push rod 7. The sleeve frame 6 is rotatably connected to the first bevel gear 3 on the left and the crushing roller 5 on the left, and the sleeve frame 6 is slidably connected to the left output shaft of the double-axis motor 2. An auxiliary screening mechanism 8 is provided at the lower part of the base 1, and a scraping mechanism 9 is provided inside the base 1.

[0023] like Figure 1 and Figure 4 As shown, the auxiliary screening mechanism 8 includes a connecting frame 81, which is connected to the lower rear side of the base 1, a screening net 82 is rotatably connected to the bottom of the connecting frame 81, and an acute-angle inclined structure is formed between the screening net 82 and the base 1. Two left-right symmetrical guide frames 83 are connected to the lower front side of the base 1, and the guide frames 83 are slidably connected to the screening net 82. Two first springs 84 are connected between the left and right sides of the front of the screening net 82 and the adjacent guide frames 83.

[0024] It should be noted that the sand making device is a kind of equipment used to produce artificial sand, which is usually used in the fields of construction, highways, railways, water conservancy projects and concrete mixing plants. It processes natural rocks through crushing, grinding and other processes to produce sand materials that meet specific specifications. Existing sand making devices mostly use artificial control of two motors to run at the same time, driving the crusher to complete the crushing process. This method is more complicated and it is inconvenient to control the distance between the sand crushing rollers and thus control the sand force by artificial control, and the accuracy is difficult to grasp. Before using the device, first fix the device and install it, then throw the raw rock into the The double-shaft motor 2 is then turned on. The left and right output shafts of the double-shaft motor 2 both drive the adjacent first bevel gear 3 to rotate, so that the corresponding second bevel gear 4 drives the adjacent crushing roller 5 to rotate in opposite directions. When it is necessary to control the degree of crushing and the particle size of the sand material, the hydraulic push rod 7 on the upper left side of the front face of the base 1 can be turned on. The telescopic end of the hydraulic push rod 7 slides downward, causing the sleeve frame 6 to slide to the left, thereby driving the first bevel gear 3 on the left and the crushing roller 5 on the left to slide to the left, and then adjusting the spacing between the crushing rollers 5, thereby adjusting the degree of crushing of the sand material and the particle size of the sand material.

[0025] It is also necessary to explain that the sand making device includes an auxiliary screening mechanism 8. When the crushing work is in progress, the crushed sand is screened through the screening net 82 at the discharge port at the lower part of the base, and the large particles of sand are discharged on the screening net toward the guide frame 83. When the large particles of sand on the screening net 82 continue to increase, the screening net 82 compresses the first spring close to the ground downward, the discharge space of the large particles of sand is increased, the flow rate is increased, the sand making time is reduced, and the small particles of sand are discharged downward through the screening net 82, thereby achieving the effect of separating and discharging particles of different specifications.

[0026] Example 2

[0027] like Figure 2 and Figure 5 As shown, the scraping mechanism 9 includes a guide block 91, and two guide blocks 91 are connected to the left and right sides of the trapezoidal pouring table on the base 1. Scraping plates 92 are slidably arranged between the front and rear adjacent guide blocks 91, and two second springs 93 are connected between the guide blocks 91 and the adjacent scraping plates 92.

[0028] It should be noted that in the sand making process, residual stones may stick to the crushing roller 5. When there are too many residual stones, it is easy to cause blockage or abnormal rotation of the sand making device. When the device operates normally, the residual stones sticking to the crushing roller 5 will contact the scraper plate 92. At this time, the scraper plate 92 will clean and scrape the sticking residual stones to prevent the residual stones from getting stuck on the crushing roller. In this process, the second spring 93 will always keep the scraper plate 92 buffered to prevent the scraper plate 92 from always being in hard contact with the adjacent crushing roller 5, thereby reducing the loss to the crushing roller 5.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
