[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] like Figure 1-4 As shown, an automatic feeding device for a concrete mixing plant includes a support frame 1, a dust collection structure 2, an automatic discharge structure 4, and a connecting conduit 3. The automatic discharge structure 4 is partially inserted into the support frame 1. The support frame 1 is composed of four supports and four plates welded to the top and bottom. In order to prevent the support frame 1 from deforming or collapsing during use, the support frame 1 should be made of a high-strength hard metal material.
[0026] To prevent raw material dust from flying around during feeding, the dust collection structure 2 is detachably connected to the support frame 1. The dust collection structure 2 includes a dust collection housing 21, an internal mounting groove 22, and a first connecting sleeve 23.
[0027] To re-enter the collected raw material dust into the automatic discharge box 42, a connecting conduit 3 is connected to the dust collection structure 2 and the automatic discharge structure 4, wherein the connecting conduit 3 is as follows: Figure 1 The design features a side "U" shape, which facilitates the collection of raw material dust, allowing it to re-enter the automatic discharge box 42.
[0028] It should be noted that the dust collection structure 2 includes a dust collection housing 21 detachably connected to the top of the support frame 1. The dust collection housing 21 is a hollow shell, and to ensure normal operation during use, its material should be hard metal. The dust collection housing 21 has an internal mounting groove 22 for connecting a suction fan. The internal mounting groove 22 is a slot designed inside the dust collection housing 21, and the suction fan is installed by bolts, etc. During use, the suction fan is connected to the external control panel via wires. The input end of the suction fan is electrically connected to the output end of the control panel, and the suction fan is electrically connected to an external power source. On the side of the internal mounting groove 22 away from the support frame 1, there is a first connecting sleeve 23. The first connecting sleeve 23 is connected to the internal mounting groove 22, which facilitates the re-entry of collected raw material dust into the automatic discharge structure 4. The first connecting sleeve 23 is connected to the internal mounting groove 22.
[0029] The automatic discharging structure 4 includes an automatic discharging box 42 inserted into the support frame 1. The longitudinal section of the automatic discharging box 42 is designed as an equilateral trapezoid, and the automatic discharging box 42 is as follows: Figure 4The diagram shows a longitudinally through-hole design for automatic material discharge. The automatic discharge box 42 has a second connecting sleeve 43 located below the midpoint of its longitudinal direction. Specifically, the suction machine draws raw material dust from the suction housing 21 into the automatic discharge box 42 through the first connecting sleeve 23, the connecting conduit 3, and the second connecting sleeve 43. During use, the dusty raw material may cause blockage in the automatic discharge box 42. The design of the second connecting sleeve 43 adds a flowable air chamber to the lower half of the automatic discharge box 42, preventing the material from becoming stationary. This flowable air chamber reduces the probability of dust accumulation in the automatic discharge box 42.
[0030] The second connecting sleeve 43 extends to the outside of the automatic discharge box 42. The two ends of the connecting tube 3 are detachably connected to the second connecting sleeve 43 and the first connecting sleeve 23 respectively. The connecting tube 3 is connected to the second connecting sleeve 43 and the first connecting sleeve 23 respectively by bolts and flanges, which facilitates the disassembly, maintenance and replacement of the connecting tube 3 during use.
[0031] The effect achieved by the entire embodiment is that the suction machine will draw the raw material dust at the position of the dust collection housing 21 into the automatic discharge box 42 through the first connecting sleeve 23, the connecting conduit 3, and the second connecting sleeve 43. At this time, due to the dusty raw material, the automatic discharge box 42 may be blocked by raw material dust. The design of the second connecting sleeve 43 adds a flowable air chamber to the lower half of the automatic discharge box 42, so that the automatic discharge box 42 is not fixed. The additional flowable air chamber in the automatic discharge box 42 will reduce the probability of raw material dust accumulation in the automatic discharge box 42. At the same time, the connecting conduit 3 is connected to the second connecting sleeve 43 and the first connecting sleeve 23 by bolts and flanges respectively, which facilitates the disassembly, maintenance and replacement of the connecting conduit 3 during use.
