Drawings
The drawings are only intended to illustrate and explain the present invention and do not limit the scope of the invention. Wherein,
fig. 1 shows a schematic top plan view of a concrete mixing plant for a concrete mixing plant according to an embodiment of the present invention.
Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
The utility model provides a modified concrete mixing plant, this concrete mixing plant store system, control system by concrete mixing equipment, material weighing system, material conveying system, material and constitute. Further, the utility model discloses a concrete mixing plant's improvement part lies in providing a concrete mixing equipment who improves the structure. Fig. 1 is a schematic top plan view of a concrete mixing plant according to an embodiment of the present invention, i.e. the other structures constituting the concrete mixing plant are omitted from the drawing, and only the main improved structure of the improved concrete mixing plant 1 is shown.
As shown in fig. 1, the concrete mixing plant 1 of the present invention comprises a cylindrical casing 2, the feed inlet 21 of the concrete mixing plant 1 is located above one side of the casing 2, and the discharge outlet 22 of the concrete mixing plant 1 is located below the other side of the casing 2. The feed inlet 21 and the discharge outlet 22 of the existing concrete mixing equipment are generally symmetrically arranged above and below the shell, and are also arranged in the area range where the feed inlet and the discharge outlet are positioned during mixing, concrete materials are often accumulated in the middle of the shell before being uniformly mixed and are easy to block, and particularly, mixing blades are easy to damage when water is not sufficiently added under the irregular operation condition. The utility model discloses an in this modified embodiment, provide the feed inlet 21 and the discharge gate 22 of biasing in two directions, the material gets into from one side when initial, through helical blade's promotion reciprocating motion in whole casing, can reduce the dead probability of card, is unlikely to damage the blade because the material is piled up the jam simultaneously.
In addition, as can be seen from the figure, the concrete mixing plant 1 of the present invention has two parallel screw shafts 3 installed in the casing 2, each screw shaft 3 has a helical blade 31, and the blades 31 on the two parallel screw shafts 3 are arranged in a mirror image with opposite helical directions. Specifically, the blades 31 are composed of stirring arms and stirring blades (not shown), the stirring blades are fixed to the screw shafts 3 by the stirring arms, and the blades 31 on the two screw shafts 3 are integrally formed with the screw shafts 3 as two sets of helical blades 31 having the same lead and lead angle but having opposite helical directions. When the screw stirring machine works, the speed reducing motors 41 and 42 respectively drive the two screw shafts 3 to rotate along one direction through the shaft couplers, the positive and negative groups of blades 31 on the screw shafts 3 stir materials, and due to the spiral angle, the blades 31 push the materials in the shell 2 to the other side from one side and push the materials back to the original position from the other side in a circulating manner when working, so that the materials are fully stirred, and a more ideal stirring effect is obtained. The utility model discloses an in the preceding embodiment, because feed inlet 21 and discharge gate 22 are the biasing setting, consequently the material is the reciprocal circulation promotion between feed inlet 21 and discharge gate 22, even if there is the transport dead angle in the position of feed inlet 21, because discharge gate 22 is biased in one side, can not take place not the concrete of intensive mixing directly from the discharge gate exhaust condition yet, avoided concrete quality to reduce.
In another embodiment of the present invention, the rotation directions of the blades 31 on each screw shaft 3 in the central range of the discharge port 22 are opposite, as shown in the figure. Because the material situation difference among the concrete mixing equipment 1 is great, let the good concrete of stirring flow out, the condition that the preceding velocity of flow is too big and behind cutoff can appear sometimes, the condition that the velocity of flow is too slow and block up can appear sometimes, for you avoid above-mentioned these circumstances, this embodiment has set up the opposite blade 31 of direction of rotation in the central range of discharge gate 22, the benefit of setting up like this can be in the position of discharge gate 22, from both sides with the closely compaction of concrete, make it keep certain compactness, thereby can control the size of the delivery capacity of the concrete of unloading, avoid appearing the situation of artesian and jam, the measurement of being convenient for on the one hand, on the other hand can avoid equipment to damage because of blockking up.
In another embodiment of the present invention, the pitch of each blade 31 on the screw shaft 3 in the range of the feed port 21 gradually increases from the feed port 21 to the discharge port 22. Further, in another embodiment, the diameter of the blade 31 on each screw shaft 3 in the range of the feed opening 21 from the feed opening 21 to the discharge opening 22 is gradually increased. The two embodiments are arranged to be the same, that is, within the range of the feeding port 21, the materials are conveyed from the feeding port 21 to the discharging port 22 in a gradual mode, so that the problem that the materials are not conveyed uniformly to cause unsmooth arching and conveying of the materials is avoided, and the equipment is prevented from being blocked and damaged due to the collapse of the materials. Further, since the material is subjected to the reciprocating stirring, the pitch and diameter of the blades 31 of each screw shaft 3 between the feed port 21 and the discharge port 22 are maintained to be the same.
From the above-mentioned embodiment of the utility model, the utility model discloses screw axis 3 to concrete mixing equipment 1 has carried out meticulous design to discharge gate 22 along feed inlet 21, at the screw axis part that discharge gate 22 corresponds to the center of discharge gate 22 is border on, and the rotation of blade 31 is opposite, and in the within range that feed inlet 21 corresponds, blade 31 is along the ascending pitch of the direction of material quilt conveying grow gradually, and the diameter of blade 31 grows gradually. Therefore, the utility model has the advantages that the rotating directions of the blades corresponding to the spiral shaft part corresponding to the discharge port are opposite; moreover, only the screw shaft portion corresponding to the feed port is gradually increased in pitch in the direction in which the material is conveyed, and the diameter of the blade is gradually increased. The design mode can adopt the same design for most parts of the whole screw shaft, and only needs to adopt different designs for smaller parts at two ends of the screw shaft, thereby greatly reducing the manufacturing difficulty and cost of the screw shaft.
