Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixing equipment, in particular to a cutting mechanism of a sand and gravel processing system. Background Art
[0002] Sand and gravel concrete mixing equipment, also known as concrete mixing machinery or concrete mixing plants, is an indispensable and important equipment in modern construction projects. It is mainly used to mix cement, sand, stone, water and other raw materials in a certain proportion to make concrete.
[0003] In the sand and gravel concrete mixing equipment, first the sand and gravel and concrete are transported separately through the conveying equipment, and then the sand and gravel and concrete are put into the equipment for mixing and stirring. In severe cold weather, since water stains are easily attached to the outer surface of the sand and gravel, the water stains will stick the sand and gravel together by freezing, causing the sand and gravel to clump together and become too large in volume. Subsequently, the sand and gravel enter the mixing equipment and are stirred with the concrete by the mixing blades, making it impossible for the clumped sand and gravel to be effectively mixed with the concrete. At the same time, the larger sand and gravel will generate greater friction with the mixing blades after clumping, which will lead to damage to the mixing blades. At the same time, the excessively large sand and gravel clumps can easily cause the mixing equipment to become stuck. Utility Model Content

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0031] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.
[0032] Example 1
[0033] Reference Figures 1 to 4 The figure shows the first embodiment of the present invention, which provides a cutting mechanism for a sand and gravel processing system. The device includes a buffer element 100, including a feeding box 101, a rectangular block 102 symmetrically connected to the feeding box 101, and a buffer assembly 103 symmetrically arranged on the feeding box 101, which prevents the feeding box 101 from being damaged by collision with the rectangular groove plate 303a during the up and down bumping process.
[0034] The cutting element 200 includes double spiral cutters 201 arranged in a linear array and rotatably connected to the feeding box 101, and a transmission assembly 202 symmetrically arranged on the feeding box 101, thereby achieving the effect of cutting sand and gravel of different volumes.
[0035] It should be noted that a drive motor is installed inside the double spiral blade 201, and the drive motor is electrically connected to an external control device.
[0036] During use, after sand and gravel are put into the feeding box 101, the personnel then adjust the buffer element 100 so that the buffer element 100 starts to cut the sand and gravel, avoiding the friction between the sand and gravel that are too large and the mixing blades installed inside the mixing equipment, thereby ensuring the service life of the mixing equipment. The cutting element 200 is then adjusted through the buffer element 100 so that the buffer element 100 can vibrate up and down during the process of cutting the sand and gravel, avoiding the phenomenon of jamming between the sand and gravel and the cutting element 200.
[0037] Example 2
[0038] Reference Figures 1 to 5FIG2 is a second embodiment of the present invention, which is different from the first embodiment in that: the buffer assembly 103 includes a sliding rod 103a that is slidably connected to the rectangular block 102, a baffle 103b connected to the sliding rod 103a, and a spring 103c that is sleeved under the sliding rod 103a, and the top of the spring 103c is fixedly connected to the rectangular block 102.
[0039] Furthermore, the transmission assembly 202 includes a fixed rod 202a connected to the double spiral cutter 201, a gear 202b connected to the end of the fixed rod 202a away from the double spiral cutter 201, a T-shaped gear rod 202d rotatably connected to the feeding box 101, a toothed belt 202c transmission-connected between the gear 202b and the T-shaped gear rod 202d, and a roller 202e symmetrically connected to the T-shaped gear rod 202d. The fixed rod 202a rotates through the inside of the feeding box 101.
[0040] During use, after sand and gravel are put into the feeding box 101, the personnel then use the external control device to control the drive motor installed inside the double spiral knife 201 and the equipment to use the power supply, thereby making the double spiral knife 201 start to rotate. The double spiral knife is powered by the motor, which is usually installed inside the equipment and rotated by electricity. After the motor is started, it will drive the double spiral knife to rotate rapidly, and the double spiral knife will also slowly move along the predetermined cutting line. During the cutting process, the blade will continuously move back and forth to ensure the smooth progress of the entire cutting process, so that the double spiral knife 201 can cut the sand and gravel put in, avoiding the friction between the sand and gravel that is too large and the stirring blades, preventing the stirring blades from being damaged, and ensuring the working performance of the mixing equipment;
[0041] During the rotation of the double spiral knife 201, the double spiral knife 201 drives the fixed rod 202a to rotate inside the feeding box 101, so that the fixed rod 202a drives the gear 1 202b to rotate synchronously, and the gear 1 202b drives the T-shaped gear rod 202d to rotate synchronously on the feeding box 101 through the toothed belt 202c connected thereto. When the T-shaped gear rod 202d rotates, the T-shaped gear rod 202d drives the roller 202e to rotate synchronously.
[0042] The remaining structures are the same as those of Example 1.
[0043] Example 3
[0044] Reference Figures 1 to 6The third embodiment of the present invention is shown in FIG. 2 , which is different from the second embodiment in that: the vibration element 300 includes a fixing frame 301, a conical funnel 302 symmetrically connected to the fixing frame 301, and an interference assembly 303 arranged on the fixing frame 301, thereby preventing sand and gravel from accumulating on the double spiral cutter 201 during the cutting process and causing blockage.
[0045] Furthermore, the interference component 303 includes a rectangular groove plate 303a connected to the fixed frame 301, a limiting groove 303b symmetrically opened on the rectangular groove plate 303a, and a triangular interference block 303c symmetrically connected to the rectangular groove plate 303a. The size of the limiting groove 303b is adapted to the size of the feeding box 101, and the feeding box 101 slides inside the limiting groove 303b. The triangular interference block 303c is located below the roller 202e. The rectangular groove plate 303a is fixedly connected to the slide rod 103a, and the bottom end of the spring 103c is fixedly connected to the rectangular groove plate 303a, thereby achieving the effect of intermittent vibration of the feeding box 101.
[0046] During use, as the roller 202e rotates, the roller 202e comes into contact with the inclined surface of the conical funnel 302, and then the conical funnel 302 comes into contact with the roller 202e, so that the roller 202e drives the feeding box 101 to move upward inside the limiting groove 303b through the T-shaped gear rod 202d. As the feeding box 101 moves upward, the feeding box 101 pulls the spring 103c upward through the rectangular block 102. When the roller 202e moves to a position where it no longer conflicts with the conical funnel 302, the feeding box 101 moves downward rapidly under the contraction of the spring 103c. At the same time, as the feeding box 101 moves downward, the feeding box 101 moves downward rapidly. The movement is an accelerated movement, so the downward force generated by the feeding box 101 will also become larger. Therefore, the spring 103c will be compressed during the downward movement of the feeding box 101 until the downward movement speed of the feeding box 101 becomes zero. At this time, the spring 103c will stretch upward again under the elastic action of the stretch, and then the spring 103c will drive the feeding box 101 to move synchronously through the rectangular block 102 until the spring 103c no longer stretches and contracts. At this time, the feeding box 101 remains stationary again, and by adjusting the vibration element 300, the buffer element 100 and the cutting element 200 can vibrate intermittently, avoiding the blockage of sand and gravel during the cutting process, and thus avoiding the problem of the double spiral knife 201 getting stuck.
[0047] The remaining structures are the same as those of Example 2.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
