Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a sand and stone mixing device. Background Art

[0002] When producing concrete, in addition to using larger particles of stones as coarse aggregates, it is also necessary to mix small particles of sand and stones as fine aggregates. During the process of mixing sand and stones, horizontal mixing mixers or vertical mixing mixers are commonly used equipment. However, the inventor found that during the mixing process, since the sand and stones are in a dry state during stirring, the tumbling and mixing action causes the feeding port of the mixer to lift and generate dust from time to time, resulting in a dust phenomenon at the mixing site. In addition, after the mixing is completed, the discharging often depends on the self-weight of the material for discharging, and the accumulated material is likely to block in the discharging pipe.

[0024] Embodiment

[0025] Refer to the attached drawings of the specification Figure 1 to attached drawing Figure 3 as shown;

[0026] Preferred technical solution of the sand and stone mixing device:

[0027] This embodiment includes:

[0028] It includes a frame 1, a machine body 9 fixed at the upper layer position inside the frame 1, and an anti-clogging blanking pipe mechanism 2 fixed at the blanking port at the bottom of the machine body 9. Two screens 3 are fixed at the top feeding port of the machine body 9, and two dust covers 4 are hinged at the edge position of the top surface of the machine body 9; the anti-clogging blanking pipe mechanism 2 includes a blanking pipe 21, an inclined pipe 22 welded on the outer surface of the blanking pipe 21 in an inclined manner, and a micro air pump 25 connected to the air inlet end of the inclined pipe 22, and a solenoid valve 24 is arranged between the micro air pump 25 and the inclined pipe 22.

[0029] A driving motor 5 is fixed on the left side wall of the frame 1 through a bracket. The power output end of the driving motor 5 is connected through a coupling to a ribbon stirring paddle 8 penetrating into the inner cavity of the machine body 9. A round hole for the ribbon stirring paddle 8 to penetrate is opened on the left side surface of the machine body 9, and a bearing matching the shaft body of the ribbon stirring paddle 8 is arranged inside the round hole.

[0030] A through hole for the inclined pipe 22 to penetrate is provided on the outer surface of the blanking pipe 21, and the inclined pipe 22 is in an inclined posture of 100°-130° with the central axis of the blanking pipe 21 as the base point. A pipe joint 23 is installed at one end of the inclined pipe 22 away from the blanking pipe 21, and the other end of the pipe joint 23 is connected to the air outlet end of the micro air pump 25; a through hole for the blanking pipe 21 to penetrate into the interior is provided on the bottom surface of the machine body 9, and the interior of the through hole and the outer surface of the blanking pipe 21 are filled with sealant.

[0031] A vibration motor is installed on the bottom surface of the sieve mesh 3 to vibrate and screen the sand and stone materials passing through the sieve mesh 3. Four groups of hinges 6 are installed on the back surface of the machine body 9, and the other ends of the hinges 6 are connected to the back surface of the dust-proof cover 4. Sound insulation cotton is fixedly laid on the bottom surface of the dust-proof cover 4 with glue.

[0032] According to the above-mentioned preferred technical solution, the working process of this technical solution is described as follows:

[0033] When the sand and stone materials are batch-fed into the machine body 9, the sand and stone materials need to be screened by the sieve mesh 3. Under the combined action of the vibration motor at the bottom of the sieve mesh 3, the sand and stone materials quickly pass through the sieve mesh 3, and larger stones or sundries such as plastic bags and branches will be screened out. After removing these sundries, the dust-proof cover 4 is covered on the upper port of the machine body 9 by means of the hinge 6 and the handle 7. Subsequently, after the ribbon stirring paddle 8 is driven by the drive motor 5, the ribbon stirring paddle 8 will stir and mix the sand and stone materials inside the machine body 9. At the same time, due to the sound insulation cotton at the bottom of the dust-proof cover 4 and the sealing effect, the dust generated during the mixing process will not be emitted, and at the same time, there will be no significant noise when the sand and stone are stirred and transferred to the dust-proof cover 4.

[0034] After the sand and stone are mixed for a period of time, the mixed sand and stone materials are allowed to fall naturally by opening the valve at the bottom port of the blanking pipe 21. When the materials are blocked inside the blanking pipe 21, the solenoid valve 24 is opened and the micro air pump 25 generates pressurized gas into the inclined pipe 22, and the inclined pipe 22 is used to blow the materials inside the blanking pipe 21 to prevent it from being blocked.

[0035] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
