Description

Technical Field

[0001] This utility model relates to the field of road and bridge technology, and in particular to a rock and soil grinding device. Background Technology

[0002] Bridge deck paving refers to the protective layer laid on the bridge deck to prevent the wheels (or tracks) from directly abrading the bridge deck and to distribute the wheel load. It also provides a smooth and non-slip driving surface for vehicles. A complete bridge deck paving usually consists of the following layers from top to bottom: the paving body, the waterproof layer, and the adhesive layer.

[0003] In the prior art, such as the rock and soil grinding device for road and bridge paving with announcement number CN221334514U, there is a grinding box and a screen. The grinding box is equipped with a drive mechanism, which is connected to a crushing mechanism and a grinding mechanism to drive the crushing mechanism and the grinding mechanism to operate. The pushing device is used to push the sliding seat to rise and fall, so that the screen can be stably driven to rise and fall repeatedly to screen the material, thereby improving the efficiency of material passing through the screen. However, the rock and soil grinding device in the prior art has the problem that it cannot automatically return the screened rock and soil after screening, so it is inconvenient to use. Therefore, a rock and soil grinding device is proposed. Utility Model Content

[0004] In view of this, the present invention aims to provide a rock and soil grinding device to solve or alleviate the technical problems existing in the prior art. By installing a screening component and a lifting component, the device can not only screen the crushed rock and soil, but also lift larger rock and soil blocks again. This allows the device to automatically recycle unqualified rock and soil blocks, making the device more convenient to use.

[0005] The technical solution of this utility model embodiment is implemented as follows:

[0024] like Figure 1-4As shown, this utility model embodiment provides a soil and rock grinding device, including: a fixing component 1, on which a tumbling component 2, a crushing component 3, a grinding component 5, and a slidably fitted screening component 4 are fixedly installed; a lifting component 6 is fixedly installed on one side of the grinding component 5; the screening component 4 includes a screening box 7, a vibrating motor 8 fixedly installed on the lower side of the screening box 7, and a guide pipe 18; four springs 9 are fixedly installed between the screening box 7 and the fixing component 1; the lifting component 6 includes a housing 10 fixedly installed on one side of the grinding component 5, a first motor 11 fixedly installed on the lower side of the housing 10, and an auger 12 fixedly installed on the output end of the first motor 11; the tumbling component 2 includes a feeding shell 25 fixedly installed on the top of the fixing component 1, a second motor 13 fixedly installed on the feeding shell 25, and a tumbling disc 14 fixedly installed on the output end of the second motor 13.

[0025] In this embodiment, specifically: the fixing component 1 includes a base plate 15 and four connecting strips 16 fixedly installed on the base plate 15. The tumbling component 2, the crushing component 3, and the grinding component 5 are all fixedly connected to the four connecting strips 16. The installation of the tumbling component 2 facilitates the tumbling of the rock and soil.

[0026] In this embodiment, specifically: guide rods 17 that slide and cooperate with the screening box 7 are fixedly installed on each of the four connecting bars 16. The crushing component 3 includes a crushing shell 19, two third motors 20 fixedly installed on the crushing shell 19, and two crushing shafts 21 respectively fixedly installed on the output ends of the two third motors 20. The installation of the crushing shell 19 facilitates the collection of the crushed rock and soil.

[0027] In this embodiment, specifically: the grinding assembly 5 includes a grinding block 22 fixedly installed between four connecting bars 16, a fourth motor 23 fixedly installed on the upper side of the base plate 15, and a rotating block 24 fixedly installed on the output end of the fourth motor 23. The installation of the grinding block 22 facilitates the grinding of rock and soil.

[0028] In this embodiment, specifically: the bottom inner side of the grinding block 22 and the periphery of the rotating block 24 are provided with a plurality of grinding protrusions 2401 for grinding the rock and soil, and the periphery of the two crushing shafts 21 are provided with a plurality of crushing protrusions 2101 for crushing the rock and soil. The installation of the crushing protrusions 2101 facilitates the crushing of the rock and soil.

[0029] In this embodiment, specifically: one end of the guide pipe 18 is located on the upper side of the bottom of the shell 10, and a plurality of tumbling protrusions 1401 for tumbling the rock and soil are provided on the upper surface of the tumbling disc 14. The tumbling protrusions 1401 are provided so that the rock and soil are not easy to rotate on the tumbling disc 14.

[0030] When this utility model is in operation: when the device needs to recirculate larger rock and soil blocks, the qualified and unqualified rock and soil blocks are located inside the screening box 7. At this time, the vibration motor 8 is turned on, and the vibration motor 8 drives the screening box 7 to vibrate. The rotating screening box 7 screens the rock and soil blocks. The qualified rock and soil blocks fall into the grinding component 5, and the unqualified rock and soil blocks enter the screening box 7, the guide pipe 18, and finally enter the housing 10. At this time, the first motor 11 is turned on, and the first motor 11 drives the auger 12 to rotate. At this time, the rock and soil blocks located inside the housing 10 are lifted to the top of the housing 10, and then the rock and soil blocks fall back into the impact component 2. This cycle is repeated until the rock and soil blocks are crushed to a suitable size.

[0031] When grinding is required, the rock and soil are fed into the impact assembly 2, and the second motor 13 is turned on. The second motor 13 drives the impact disc 14 to rotate, generating centrifugal force. The rock and soil are then thrown into the lower material shell 25 by the centrifugal force of the impact disc 14. After impacting the lower material shell 25, the rock and soil fall into the crushing assembly 3. At this time, the third motor 20 is turned on, driving the crushing shaft 21 to rotate. The crushing shaft 21 crushes the rock and soil, and then the crushed rock and soil enters the screening box 7 for screening. The qualified rock and soil enters the grinding assembly 5, and the unqualified rock and soil is returned. Then the fourth motor 23 is turned on, driving the rotating block 24 to rotate. The rotation of the rotating block 24 performs the final grinding of the rock and soil, and the ground rock and soil flows out from the bottom of the grinding block 22.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
