Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: a concrete mixer with a dust removal function is shown in figures 1 and 2 and comprises a mixer body 1 and a fixing plate 2 used for fixing the mixer body, wherein the mixer body 1 is installed on the fixing plate 2 and driven by a motor to rotate, and a discharge hole 11 and a feed hole 12 used for feeding and discharging raw materials are formed in the mixer body 1. When the raw materials are stirred, the raw materials enter from the feed inlet 12 of the stirrer body 1, and the stirrer body 1 rotates forwards under the driving of the motor after the raw materials enter, so that the raw materials are stirred. After the raw materials are stirred, the motor drives the mixer body 1 to rotate reversely, so that the concrete finished products in the mixer body 1 are discharged from the discharge port 11 for workers to use.

As shown in FIGS. 1 and 2, dust-proof doors 3 are provided at both the discharge port 11 and the feed port 12 to reduce dust generated during the stirring process of the mixer body 1.

As shown in fig. 3 and 4, taking the dust-proof door 3 at the discharge port 11 as an example, the dust-proof door 3 includes two closing plates 31 for closing the discharge port and a bracket 32 for attaching the closing plates 31 to the mixer body 1.

The closing plates 31 are semicircular plates, and when the discharge hole 11 is closed by the two closing plates 31, the closing plates 31 are attached to the discharge hole 11. When the discharge port 11 is sealed by the two sealing plates 31, the straight edges of the two sealing plates 31 are attached to form a complete disc, and the diameter of the formed disc is not less than that of the discharge port 11, so that the discharge port 11 is sealed.

The bracket 32 includes an arc-shaped connecting plate 321 and a semicircular plate-shaped mounting plate 322, the connecting plate 321 is fixedly connected with the mounting plate 322, and the circumference of the semicircular plate-shaped mounting plate 322 is fixedly connected with the circumference of the arc-shaped connecting plate 321. The other end of the connecting plate 321 is fixedly connected with the mixer body 1. When the dust-proof door 3 is opened, the closing plate 31 can be accommodated in the holder 32. After the closing plate 31 is received in the bracket 32, the mounting plate 322 on the bracket 32 on the side of the closing plate 31 departing from the discharge port 11 is attached.

As shown in fig. 3 and 4, two stretching cylinders 33 are further fixedly connected to the bracket 32, the two stretching cylinders 33 are fixedly connected to the connecting plate 321 of the bracket 32, and the stretching cylinders 33 are fixedly connected to the side of the bracket 32 facing the discharge port 11. The piston rod of the stretching cylinder 33 is fixedly connected to the arc surface of the closing plate 31, and the arrangement direction of the stretching cylinder 33 is perpendicular to the straight edge of the closing plate 31. Wherein the stretching cylinder 33 is arranged in the same direction as the sliding direction of the closing plate 31. When the piston rod of the stretching cylinder 33 is ejected, the closing plate 31 is closed, and when the piston rod is contracted, the closing plate 31 slides into the bracket 32.

A sliding block 34 is convexly arranged on one surface of the closing plate 31, which is attached to the mounting plate 322 on the bracket 32, and the sliding block 34 is a T-shaped block or a wedge-shaped block, which is a T-shaped block in this embodiment. The mounting plate 322 is provided with a slide groove 35 engaged with the slide block 34, and the slide groove 35 is provided along the piston rod ejecting direction of the stretching cylinder 33. The sliding block 34 is embedded in the sliding groove 35, and the sliding block 34 can slide in the sliding groove 35 along the length direction of the sliding groove 35 under the push and pull of the stretching cylinder 33, so that when the closing plate 31 is limited to close the feed opening 12 or the discharge opening 11 again, the closing plate 31 is inclined, and the deviation is not easy to occur when the closing plate 31 closes the discharge opening 11 or the feed opening 12. Wherein, set up slider 34 into T type piece or wedge for the slider only can slide along the length direction of spout 35 when sliding in spout 35, can not deviate from other directions of spout, takes place the deviation when further preventing to seal feed inlet 12 or discharge gate 11.

As shown in fig. 4, the straight edge of the closing plate 31 is set as a triangular edge, the straight edge of the mounting plate 322 is also set as a triangular edge, and when the dust-proof door 3 is opened, the triangular edge of the closing plate 31 is coplanar with the triangular edge of the bracket 32 to form an inclined surface. The edge height of the discharge port 11 is higher than that of the support 32, the inclined plane is convenient for discharging, and a concrete finished product slides out along the inclined plane and cannot be retained on the dustproof door 3.

As shown in fig. 3 and 4, after a long time of use, some concrete may remain on the closing plate 31 and the bracket 32, and once the amount of concrete increases, the closing plate 31 may be interfered with, so that the closing plate 31 and the bracket 32 generally need to be cleaned, and during cleaning, a worker generally sprays the bracket 32 and the closing plate 31 using a water pipe to wash down the concrete adhered to the bracket 32 and the closing plate 31, thereby completing the cleaning of the bracket 32 and the closing plate 31. However, in actual use, when the closing plate 31 is stored and cleaned, water for cleaning concrete may remain in the stand 32, and it takes a long time for the worker to rotate the mixer body 1 to discharge the water in the stand 32. In order to facilitate the water in the bracket 32 to be discharged, a water outlet hole 36 is formed through the central position of the connecting plate 321 of the bracket 32, and after the dust-proof door 3 is cleaned by water, the water flows out from the water outlet hole 36 to prevent the water from being retained in the bracket 32.

The implementation principle of the embodiment is as follows: when the stirrer feeds, the dustproof door 3 at the feed inlet 12 is opened, and the dustproof door 3 at the discharge outlet 11 is closed to feed. The dust-proof door 3 at the discharge port 11 is closed to prevent dust from flying out of the discharge port 11. After the feeding is finished, the dustproof door 3 at the position of the feeding hole 12 is closed, the stirring is started, in the stirring process, the dustproof door 3 at the position of the feeding hole 12 and the dustproof door 3 at the position of the discharging hole 11 are both closed, and the dust is prevented from leaking out of the stirring machine body 1 in the stirring process. After the stirring is finished, the dustproof door 3 at the discharge port 11 is opened to discharge. During discharging, the dustproof door 3 at the feed inlet 12 is closed, so that dust is prevented from flying out of the feed inlet 12 in the discharging process.

When the dust-proof door 3 is cleaned, the closing plate 31 is closed, water is sprayed on the closing plate 31 to clean the closing plate 31, then the water is sprayed on the inner side and the outer side of the bracket 32 to clean the bracket 32, and after the bracket 32 is cleaned, the water for cleaning the dust-proof door 3 flows out of the water outlet hole 36 formed in the bracket 32 to prevent the water from being retained in the dust-proof door 3.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
