Description

Technical Field

[0001] The utility model belongs to the technical field of waste crushing, in particular to a crushing device for construction waste. Background Art

[0002] Construction waste crushing equipment is a kind of equipment specially used for processing construction waste. Its core function is to crush the abandoned building materials for subsequent reuse or disposal. These equipment are usually equipped with powerful crushing mechanism and efficient screening system, which can handle various types of construction waste, such as concrete, bricks, stones, etc.

[0003] There are many kinds of crushers on the market, such as jaw crusher, impact crusher, cone crusher, etc. Among them, jaw crusher needs to be driven by a motor in the form of belt drive. Due to the high power requirement, multiple transmission belts are generally installed between the driving pulley and the driven pulley. As we all know, the transmission belt needs a certain degree of tension during installation, and the staff needs to use tools to pry the belt onto the pulley. However, a jaw crusher needs to use multiple transmission belts at the same time. Due to the limited fatigue of the transmission belt, the transmission belt needs to be replaced regularly, which makes the installation of the transmission belt more time-consuming and labor-intensive.

[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0021] Example

[0022] The present embodiment describes a construction waste crushing device, such as Figures 1 to 6 As shown, it includes a base 1, which is a rectangular frame structure. A jaw crusher 2 is installed on the left half of the top of the base 1. The waste crushed by the jaw crusher 2 can leak out from the middle of the base 1. The jaw crusher 2 is a prior art, consisting of a frame, an eccentric shaft, a static jaw plate, a movable jaw plate, a flywheel and a driven pulley. A motor mounting seat is provided on the right half of the base, and a motor 9 is installed on the motor mounting seat. A driving pulley 4 is installed on the output end of the rotating shaft of the motor 9. The driving pulley 4 and the driven pulley are connected through a plurality of transmission belts 3. The driving pulley 4 and the driven pulley are multi-groove pulleys.

[0023] like Figure 4 and Figure 6As shown, the motor mounting seat includes a bottom plate 7, which is fixed to the top of the right half of the base 1, and a fixing frame 5 is fixed to the top of the bottom plate 7. A mounting plate 13 that is movable left and right is independently provided in the fixing frame 5, and an adjusting plate 10 that fits therewith is provided on the right side of the mounting plate 13. A first through hole that communicates left and right is opened on the mounting plate 13, and a threaded hole that communicates left and right is opened on the adjusting plate 10 corresponding to the through hole, and a threaded rod 12 that is threadedly matched therewith is passed through the threaded hole, and the left end of the threaded rod 12 independently passes through the first through hole and is rotatably connected to the left inner wall of the fixing frame 5, and a mounting hole is opened on the left inner wall of the fixing frame 5, and the left end of the threaded rod 12 is independently passed through the mounting hole, so that the rotation of the threaded rod 12 is more stable, and a second through hole that communicates inside and outside is opened on the right side wall of the fixing frame 5 corresponding to the threaded hole, and the right end of the threaded rod 12 independently passes through the first through hole The second through hole is located on the outside of the fixed frame 5. The right end of the threaded rod 12 is fixed with a connector 6 for rotating a wrench. The connector 6 is a four-corner connector. When in use, the connector 6 can be rotated by a wrench, and the threaded rod 12 is driven to rotate at the same time. The connector 6 occupies a small space and looks more beautiful. It can also prevent people without tools from rotating it. If the traditional turning handle is fixed there, it not only takes up space, but anyone can affect the equipment by its rotation. A limit ring 15 is installed on the threaded rod 12. The limit ring 15 rests on the right inner wall of the fixed frame 5. A plane thrust bearing 14 is independently installed on the threaded rod 12 between the limit ring 15 and the right inner wall of the fixed frame 5. The plane thrust bearing 14 can reduce the friction between the limit ring 15 and the right inner wall of the fixed frame 5 when the limit ring 15 rotates. The limit ring 15 and the threaded rod 12 are integrally formed.

[0024] Two springs 11 distributed front to back are arranged between the left inner wall of the fixed frame 5 and the mounting plate 13. Two first limit holes distributed front to back are opened on the mounting plate 13. Corresponding to each first limit hole, a second limit hole communicating left to right is opened on the adjustment plate 10. The same guide rod 8 is independently installed in the first limit hole and the second limit hole. The two ends of the guide rod 8 are respectively fixed on the left inner wall and the right inner wall of the fixed frame 5; the two springs 11 are independently sleeved on the guide rod 8. This section as a whole constitutes a thrust assembly for pushing the mounting plate 13 to move to the right; in production, the sum of the elastic forces of the two springs 11 must be greater than the elastic forces of all the transmission belts 3 to prevent the spring 11 from being pulled by multiple transmission belts 3 when pushing the mounting plate 13 to move to the right, resulting in the transmission belt 3 between the active pulley 4 and the driven pulley not being tightened enough; the guide rod 8 can further increase the stability of the mounting plate 13 during the left and right movements, thereby increasing the stability of the installation of the motor 9. During installation, the front and rear side walls of the mounting plate 13 are both attached to the front and rear inner side walls of the fixed frame 5; in addition, the two springs 11 can be replaced with a spring 11 with greater elastic force, which is independently mounted on the threaded rod 12, and its two ends are respectively pressed against between the mounting plate 13 and the left inner side wall of the fixed frame 5, which also serves the purpose of pushing the mounting plate 13 to move to the right;

[0025] The threaded rod 12 rotates in place during operation and does not extend outward to occupy space as it rotates. The right end of the threaded rod 12 is pressed against the right inner wall of the fixed frame 5 through the limit ring 15 to prevent the threaded rod 12 from moving to the right.

[0026] The threaded rod 12 is then driven to rotate by rotating the connector 6 with a wrench. The threaded rod 12 drives the adjusting plate 10 to move to the left by cooperating with the thread of the threaded hole. The adjusting plate 10 pushes the mounting plate 13 to move to the left, overcoming the elastic force of the spring 11, so that the spacing between the active pulley 4 and the driven pulley becomes smaller. At this time, multiple transmission belts 3 can be easily put into different wheel grooves on the active pulley 4 and the driven pulley, and then the wrench is rotated in the opposite direction to move the adjusting plate 10 to the right. The mounting plate 13 moves to the right accordingly under the thrust of the spring 11. All the transmission belts 3 are tightened by the elastic force of the spring 11 until the transmission belts 3 are tightened to a suitable tightness, and the rotation of the threaded rod 12 is stopped. In this way, the installation of all the transmission belts 3 can be completed at one time, saving time and effort.
