[0039] The present invention provides a crack-resistant concrete production equipment. Compared with the prior art, in the process of feeding materials into the storage hopper 2, the materials first enter the screen drum 4 in the barrel 3, and after secondary screening by the screen drum 4, the materials in the screening chamber 2 42 enter the discharge chamber 46 and finally fall into the storage hopper 2; after screening by the screen drum 4, the particle size of the materials can be made more uniform, and the problem of uneven material sedimentation can be reduced, thereby reducing the cracking of the concrete; the barrel 3 is connected to the storage hopper 2 through a plurality of elastic parts 5, so during the feeding process, the barrel 3 will vibrate, and then the materials in the screen drum 4 will be screened, and finally the materials in the screening chamber 2 42 will fall into the storage hopper 2; the stirring device in the stirring device 1 can stir the materials, so that a variety of materials are evenly mixed.

[0040] It should be noted that the stirring equipment 1 and the stirring device inside it are both existing technologies and will not be described in detail here; by setting the bottom end of the barrel 3 in the storage hopper 2, the material falling into the barrel 3 can directly enter the storage hopper 2, reducing the situation where the material falls outside the storage hopper 2; since there is a gap between the outer peripheral wall of the barrel 3 and the inner peripheral wall of the storage hopper 2, during the feeding process, it is convenient for the barrel 3 to vibrate, and then the material in the screen drum 4 is screened.

[0041] Exemplarily, a retaining ring 47 is fixed on the top of the sieve cylinder 4, and the retaining ring 47 contacts the top of the barrel 3; the outer wall of the sieve cylinder 4 has a plurality of threaded holes, and the side wall of the barrel 3 has through holes aligned one by one with the threaded holes; after the sieve cylinder 4 is placed in the barrel 3, the sieve cylinder 4 is fixed to the barrel 3 by bolts.

[0042] Exemplarily, the feeding device can feed materials through a belt conveyor, which is a prior art and will not be described in detail here; the belt conveyor transports the materials and transports the materials into the screen drum 4; through the vibration of the screen drum 4, the materials falling into the screen drum 4 can be screened, and finally the materials in the screening chamber 2 42 fall into the storage hopper 2.

[0045] Exemplarily, the material collecting device may be a material collecting barrel or a material collecting bag; both the material collecting barrel and the material collecting bag are prior art and will not be described in detail here.

[0046] In some embodiments, Figures 1 to 11 As shown, discharge port 1 and discharge port 2 are respectively located on the side walls where the screen drum 4 contacts the material drum 3. Through the above arrangement, when discharging materials, the amount of materials entering the storage hopper 2 can be reduced, thereby reducing the amount of materials in the screening chamber 1 41 and the collecting chamber 43 falling into the storage hopper 2.

[0048] In some embodiments, Figures 1 to 11 As shown, the portion of the barrel 3 located outside the storage hopper 2 has a first vibration frame 51, and the top of the storage hopper 2 has a second vibration frame 52; wherein, a plurality of elastic members 5 are arranged between the first vibration frame 51 and the second vibration frame 52, and the two ends of each elastic member 5 are respectively connected to the first vibration frame 51 and the second vibration frame 52; and the outer side wall of the storage hopper 2 has a vibration mechanism 6 that can reciprocate and push one side of the first vibration frame 51.

[0049] It should be noted that the elastic member 5 includes a spring, and both ends of the spring are fixedly connected to the first vibration frame 51 and the second vibration frame 52 respectively; when the vibration structure provides an oscillating force to the barrel 3, the barrel 3 will continue to vibrate under the elastic force of several springs, thereby screening the material in the screen cylinder 4; by setting a plurality of springs, the connection between the barrel 3 and the storage hopper 2 can be strengthened, thereby facilitating the vibration of the storage hopper 2.

[0050] In some embodiments, Figures 1 to 11 As shown, the vibration mechanism 6 includes a push rod 61, a cam 62 and a drive motor 63; the top end of the push rod 61 passes through the second vibration frame 52 and contacts the bottom of the first vibration frame 51; the cam 62 is rotatably set on the outer wall of the storage hopper 2; the outer peripheral wall of the cam 62 contacts the bottom end of the push rod 61; the output shaft of the drive motor 63 is connected to one of the centers of the cam 62 to drive the cam 62 to rotate; a support frame 64 for supporting the drive motor 63 is provided on the outer wall of the storage hopper 2.

[0051] It should be noted that the support frame 64 is connected to the outer wall of the storage hopper 2, and the support frame 64 has an avoidance space for the rotation of the cam 62. By driving the cam 62 to rotate by the driving motor 63, the cam 62 can drive the push rod 61 to move up and down, and then the push rod 61 pushes the first vibration frame 51 up and down, thereby achieving the purpose of vibration of the barrel 3; through the above-mentioned arrangement of the present application, the rotation of the cam 62 can be converted into the vibration of the barrel 3, and then the material in the screen barrel 4 can be screened.

[0052] Exemplarily, one end of the push rod 61 that contacts the first vibration frame 51 has an arc surface, and when the first vibration frame 51 is tilted, the first vibration frame 51 contacts the arc surface of the push rod 61 .

The cross section of the slide groove 65 is a T-shaped structure. The roller 66 is located in the slide groove 65, and the two ends of the roller 66 are respectively in contact with the two opposite sides of the slide groove 65; through the above arrangement, the roller 66 and the cam 62 can be limited, so that the roller 66 only moves in the slide groove 65.

By starting the dust removal equipment, the smoke and dust can enter the dust suction pipe 7 and finally enter the dust removal equipment. Through the above-mentioned settings of this application, the smoke and dust dissipated into the air during the feeding process can be reduced.

[0057] Exemplarily, the holder 48 is fixed to the top of the sieve drum 4 by bolts, and the dust suction pipe 7 can be fixed to the top of the sieve drum 4 by inserting the dust suction pipe 7 into the holder 48, thereby improving the connection between the dust suction pipe 7 and the sieve drum 4.
