Referring to fig. 1 to 7, a mixing device for hydraulic engineering construction comprises a screening box 3 for screening raw materials and a mixing box 2 for mixing the raw materials. The material mixing device can be arranged by using the same box body in a stacking mode in sequence according to the requirements of the material screening and mixing process, or can be freely selected by adopting an independent box body in a modularized mode and arranged in a stacking mode in sequence. Preferably, in the following embodiments, the material mixing device for hydraulic engineering construction is described by taking the characteristic of a process of firstly screening and then mixing as an example.

Example 1

As shown in fig. 1, the stacked screening boxes 3 and the mixing boxes 2 are stacked in a modular manner from top to bottom, a feeding port for feeding materials is arranged at the top of the screening box 3, a discharging port of the screening box 3 is arranged at the side opposite to the feeding port, and the discharging port is butted with the feeding port of the next-stage screening box 4 or the mixing box 2, so that the screened materials can enter the mixing box 2 through the butting portion to be mixed. The diapire or the lateral wall of mixing box 2 are equipped with the discharging pipe that is used for discharging the material in 2 chambeies of mixing box 2.

Between the feed inlet and the discharge gate of screening case 3, still mobilizable be equipped with at least one deck use the screen frame 4 of screen cloth screening material. Preferably, as shown in fig. 2 and 4, the screen frame 4 is of the same shape as the screening box 3 and has a circumference smaller than the inner edge of the screening box 3. In the through-hole (be the reel socket) that reel 4 set up by 3 lateral parts of screening case inserted screening case 3, the accessible symmetry sets up the L shape slide of 3 in the screening case, or uses the mode of slide rail bearing, slidable sets up between the feed inlet and the discharge gate of screening case 3.

During the use, pour into the feed inlet of screening case 3 more than one kind of material simultaneously or in proper order, make the material fall on the screen cloth in the reel 4, the material that is less than the screen cloth passes through and falls into the cavity of mixing box 2 through the material export of screening case 3 and the feed inlet of mixing box 2 by the screen cloth hole, realizes the screening and the mixture of material.

Example 2

Further, for realizing better screening effect, avoid the material of screening in-process to block the screen cloth, this embodiment increases the actuating mechanism of drive reel on embodiment 1's basis, makes the screen cloth in reel 4 and reel 4 can be at screening case 3 internal reciprocating motion to realize the vibrations screening effect to the material in reel 4.

As shown in fig. 2 to 4, as in embodiment 1, the screen box 3 is movably and detachably provided with more than one screen frame 4. In order to realize the vibration of the screen frame 4, screen frame driving devices are further arranged on the screening box 3 and the screen frame 4.

Reel drive arrangement includes the fixed cover 7 that is equipped with in the relative one side of reel socket on screening case 3, fixed cover 7 is used for fixed motor 6. The motor 6 is preferably an internal rotor motor, the stator housing of which is fixedly connected to a stator housing 7. The transmission shaft of the motor 6 is fixedly connected with the circle center of one or more cam base rings, and the curved surface of the cam is in rolling friction with the outer wall of the adjacent screen frame 4. The screen frame 4 is formed as a follower driven by a cam, and is moved toward the inlet side of the screen frame 4 by the cam curved surface. Preferably the number of said cams should correspond to the number of frames.

As shown in fig. 1 to 4, the screen frame 4 is in the same plane as the cam, and is separated from the cam after being pushed out by the cam, so that the material cannot be screened by reciprocating motion. The frame drive should therefore also include frame return means for maintaining the frame 4 in rolling frictional contact with the curved surface of the cam at all times. The reset device of the screen frame 4 comprises a first connecting plate 11, a spring 12, a pressing plate 9 and a fixing mechanism for locking the position relation between the first connecting plate 11 and the screening box, wherein the fixing mechanism consists of a rotating rod 15 and a clamping block 16 which is matched with the rotating rod to realize locking.

Further, when the number of the screen frames 4 is even, the number of the screen frames is the same as that of the cams, and the screen frames respectively roll and rub the outer edges of the corresponding cams.

Example 5

Preferably, said second connecting plate 14 takes a shape matching the service interface, as shown in fig. 3, and is fixedly connected to the sieve box 3 by means of bolts 13.

Example 6
