Description

Technical Field

[0001] This utility model belongs to the field of sand and gravel crushing technology, and more specifically, it relates to an environmentally friendly sand and gravel crushing device. Background Technology

[0002] Sand and gravel refer to a loose mixture of sand grains and gravel. Geologically, mineral or rock particles with a diameter of 0.074–2 mm are called sand, while those larger than 2 mm are called gravel or angular gravel. The difference between the two lies in the degree to which they are rounded. If the gravel in sand and gravel is mostly gravel, it is called sandy gravel. In everyday life, some people also refer to sandstone as sand and gravel.

[0003] Based on the above, the inventors have discovered the following problems: During the mining process, sand and gravel need to be crushed for subsequent use. Currently used crushing devices typically have their feed inlets located at the top of the crushing shaft, through which materials are fed and crushed. In actual use, due to the crushing and compression, sand and gravel may burst out of the feed inlet, causing injury to workers. At the same time, dust generated during the crushing process will be discharged from the feed inlet, causing significant pollution and affecting the operation of workers.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an environmentally friendly sand and gravel crushing device, in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an environmentally friendly sand and gravel crushing device. This device solves the problem that current sand and gravel crushing methods may cause sand and gravel to burst out of the feed inlet, injuring workers. Additionally, the dust generated during the crushing process may be discharged from the feed inlet, causing significant pollution and affecting workers' operations.

[0006] The purpose and effectiveness of this environmentally friendly sand and gravel crushing device are achieved through the following specific technical means:

[0007] An environmentally friendly sand and gravel crushing device includes a frame, a crushing box mounted on the frame, an adjusting seat mounted on one side of the crushing box, a limiting frame mounted on the adjusting seat, a feed hopper mounted on the limiting frame, a movable component movably mounted inside the limiting frame, a connecting component mounted on the lower part of one side of the movable component, a connecting shaft mounted on the connecting component, a rotating shaft mounted on the adjusting seat, a rotating disk mounted on the upper part of the rotating shaft, a push shaft mounted eccentrically on the rotating disk, and a push rod mounted on the push shaft.

[0008] Furthermore, the rotating disk and the push shaft form an eccentric wheel, the push shaft is movably connected to the push rod and the connecting shaft, and the inner side of the moving part is provided with an inclined surface, which is located at the lower part of the feed hopper.

[0009] Furthermore, a first drive motor is connected to the lower end of the rotating shaft, and the output end of the first drive motor is connected to the lower end of the rotating shaft through a coupling. The first drive motor is connected to the lower part of the adjusting seat.

[0010] Furthermore, side limiting strips are installed on both sides of the inner side of the limiting frame, and side limiting sliders are installed at both ends of the moving part, with the side limiting sliders and side limiting strips slidably connected.

[0011] Furthermore, a bottom limiting strip is installed on the lower inner side of the limiting frame, and a bottom limiting slider is installed on the lower part of the moving part, with the bottom limiting slider and the bottom limiting strip slidably connected.

[0012] Furthermore, a protective enclosure is installed on the upper part of the crushing box, and a protective cover is pulled out from the upper part of the protective enclosure. A crushing shaft is installed inside the crushing box.

[0013] Furthermore, a passive toothed wheel is connected to one end of the crushing shaft, and a driving toothed wheel is connected to the passive toothed wheel via a toothed belt drive. A second drive motor is connected to the middle of the driving toothed wheel, and the output end of the second drive motor is connected to the driving toothed wheel via a coupling. The second drive motor is connected to the frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the material slides down an inclined plane to one side of the moving part, and then the first drive motor is started. The first drive motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating disk to rotate. When the rotating disk rotates, it drives the push rod to move through the push shaft. As the rotating disk continues to rotate, the push rod reciprocates, and the push rod can push the moving part to move. The moving part can push the sand and gravel into the interior of the crushing box. The feed hopper is located on the upper side of the crushing box, and the moving part can prevent the sand and gravel from splashing out of the feed port and prevent excessive dust discharge, thus improving the overall practicality.

[0016] In this invention, a second drive motor drives an active toothed wheel to rotate, which in turn drives a passive toothed wheel to rotate via a toothed belt. The passive toothed wheel then drives a crushing shaft to rotate, which crushes the sand and gravel. The crushed sand and gravel are then discharged from the bottom of the crushing box.
