Description

Technical Field

[0001] This utility model belongs to the technical field of concrete mixing devices, specifically relating to a concrete mixing device with a slag-filtering function. Background Technology

[0002] Concrete mixing plants are key equipment in construction engineering used to mix cement, aggregates (sand, stone), water, and other additives to prepare concrete. Depending on their scale and application, they can be divided into small mobile mixers and large stationary mixing plants. In small mobile concrete mixing plants, especially on some open-air construction sites, if the sand and gravel are not perfectly preserved, impurities may be mixed in. For example, large leaves or clods of soil may be mixed into the sand, and smaller clods of soil may be mixed into the gravel. Therefore, filtration and screening are necessary before concrete mixing. Current procedures involve manual filtration and drying of the slag using mesh screens, which is inefficient. Therefore, this invention proposes a concrete mixing plant with a filtration and screening function. Utility Model Content

Detailed Implementation

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-5 As shown, a concrete mixing device with a slag-filtering function includes a concrete mixer 1, a feeding component 2 on one side of the concrete mixer 1, a movable component 3 on the feeding component 2, and a slag-filtering component 4 installed on the movable component 3. The movable component 3 is used to assist the slag-filtering component 4 in rotating 180°. The slag-filtering component 4 includes a filter box 401, which has a wide-mouth design at both ends. The filter box 401 contains a first filter screen 402, a second filter screen 403, and a third filter screen 404. The first filter screen 402 is located directly below the second filter screen 403 and the third filter screen 404. The second filter screen 403 and the third filter screen 404 have the same pore size, and the pore size of the first filter screen 402 is larger than that of the second filter screen 403.

[0022] Preferably, the sidewall of the filter box 401 is connected by a first slide 405, a second slide 406 and a third slide 407 respectively. The bottom wall of the first slide 405 is aligned with the outer wall of the first filter screen 402, the second slide 406 is aligned with the inner wall of the second filter screen 403, and the third slide 407 is aligned with the outer wall of the third filter screen 404.

[0023] Preferably, the first filter screen 402 and the second filter screen 403 are inclined, one end of the third filter screen 404 is attached to one end of the second filter screen 403, and the other end of the third filter screen 404 is higher than the other end of the second filter screen 403, so that when filtering small soil clods in sand, the small soil clods can easily slide from the inclined third filter screen 404 into the third slide 407 and then slide out of the filter box 401.

[0024] Preferably, the base of the first slide rail 405, the second slide rail 406 and the third slide rail 407 are all movably connected with a gate plate 5.

[0025] In practical use, after rotating the filter screen assembly 4, when the first filter screen 402 is above the center, when... Figure 2As shown, when the first filter screen 402 is on top, it is used to filter stones. Large stones will not pass through the first filter screen 402, while some small pieces of soil will pass through the first filter screen 402 and fall to the inner surface of the second filter screen 403. The gate 5 of the first slide 405 and the gate 5 of the second slide 406 are opened. The stones pass through the first slide 405 and enter the feeding assembly 2, and finally enter the concrete mixer 1. The small pieces of soil will slide from the inner surface of the second filter screen 403 to the second slide 406 and slide out of the filter box 401.

[0026] After the filter screen assembly 4 is rotated, when the third filter screen 404 is above the filter, as shown... Figure 3 as well as Figure 4 As shown, at this time, the gate 5 of the first slide 405 and the gate 5 of the second slide 406 are closed. The worker uses a shovel to pour sand onto the third filter screen 404. The sand passes through the third filter screen 404, then through the second filter screen 403, and finally directly through the first filter screen 402 with larger gaps, and enters the feeding assembly 2, and finally enters the concrete mixer 1. Small pieces of soil will remain on the third filter screen 404. The gate 5 of the third slide 407 is opened periodically to discharge the small pieces of soil.

[0027] Ultimately, this invention enables the simultaneous filtering of small clods of soil from large stones and small clods of soil from sand when adding raw materials to the concrete mixer 1.

[0028] Preferably, the feeding assembly 2 includes a feeding trough 201 that is connected through the outer shell of the concrete mixer 1. The end of the feeding trough 201 is provided with a wide-mouth trough 202. The bottom walls of the feeding trough 201 and the wide-mouth trough 202 are inclined to facilitate the transfer of raw materials for concrete mixing into the concrete mixer 1.

[0029] Preferably, the movable component 3 includes a fixed rod 301 disposed on the side wall of the wide-mouth groove 202, a movable rod 302 disposed inside the fixed rod 301, and a rotating shaft 303 connected to the upper end of the movable rod 302 via a bearing. One end of the rotating shaft 303 is connected to the center point of the side wall of the filter box 401, and the other end of the rotating shaft 303 is provided with a handle 304.

[0030] First, the filter box 401 is raised by lifting the movable rod 302. Then, with the assistance of the rotating shaft 303, the filter box 401 can be rotated 180°. The wide-mouthed end faces of the filter box 401 are aligned with the upper end faces of the wide-mouthed groove 202. The wide-mouthed groove 202 supports the filter box 401 and effectively prevents material from leaking out from the gaps.

[0031] The working principle of this utility model is as follows: In actual use, after rotating the filter screen assembly 4, when the first filter screen 402 is above the screen, when... Figure 2As shown, when the first filter screen 402 is on top, it is used to filter stones. Large stones will not pass through the first filter screen 402, while some small pieces of soil will pass through the first filter screen 402 and fall to the inner surface of the second filter screen 403. The gate 5 of the first slide 405 and the gate 5 of the second slide 406 are opened. The stones pass through the first slide 405 and enter the feeding assembly 2, and finally enter the concrete mixer 1. The small pieces of soil will slide from the inner surface of the second filter screen 403 to the second slide 406 and slide out of the filter box 401.

[0032] First, the filter box 401 is raised by lifting the movable rod 302. Then, with the assistance of the rotating shaft 303, the filter box 401 can be rotated 180°. After rotating the filter screen assembly 4, when the third filter screen 404 is on top, as... Figure 3 as well as Figure 4 As shown, at this time, the gate 5 of the first slide 405 and the gate 5 of the second slide 406 are closed. The worker uses a shovel to pour sand onto the third filter screen 404. The sand passes through the third filter screen 404, then through the second filter screen 403, and finally directly through the first filter screen 402 with larger gaps, and enters the feeding assembly 2, and finally enters the concrete mixer 1. Small pieces of soil will remain on the third filter screen 404. The gate 5 of the third slide 407 is opened periodically to discharge the small pieces of soil.
