DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A concrete production device comprises a shell 1, a feed pipe 2 is connected through the top of the shell 1, a connection port is provided on the side wall and the bottom of the shell 1, a collection frame is fixedly connected to the side wall and the bottom of the shell 1, a driving mechanism and a crushing mechanism are arranged in the feed pipe 2, the driving mechanism comprises a servo motor 6 fixedly mounted on the inner side wall of the feed pipe 2, a first crushing roller 7 is fixedly connected to the end of the output shaft of the servo motor 6, a first gear ring 8 is sleeved on the side wall of the first crushing roller 7, and a first transmission wheel 9 is fixedly connected to the side wall of the output shaft of the servo motor 6;

[0022] The end of the crushing mechanism is meshed with the end of the driving mechanism. The crushing mechanism includes a second crushing roller 11 rotatably connected to the inner wall of the feed pipe 2. The side wall of the second crushing roller 11 is sleeved with a second gear ring 12. The end of the second gear ring 12 is meshed with the end of the first gear ring 8. Through the arrangement of the driving mechanism and the crushing mechanism, the second crushing roller 11 and the first crushing roller 7 can be driven by the servo motor 6 and the meshing between the first gear ring 8 and the second gear ring 12 to drive the second crushing roller 11 and the first crushing roller 7 to rotate in both directions, so that the sand and gravel passing therethrough can be crushed, thereby improving the mixing effect of subsequent concrete processing;

[0023] The inner side wall of the housing 1 is provided with an extrusion mechanism, and a transmission belt 3 is transmission-connected between the end of the extrusion mechanism and the driving mechanism. The extrusion mechanism includes a connecting rod 5 rotatably connected to the inner side wall of the housing 1, an eccentric wheel 4 is fixedly connected to the end of the connecting rod 5, a second transmission wheel 10 is fixedly connected to the side wall of the connecting rod 5, and a transmission belt 3 is transmission-connected between the second transmission wheel 10 and the first transmission wheel 9;

[0024] A slide groove 13 is provided on the inner wall of the shell 1, and a screening mechanism is provided in the slide groove 13. A conical baffle 18 is fixedly installed on the inner bottom of the shell 1. The screening mechanism includes a slider 14 slidably connected in the slide groove 13, and a first spring 15 is fixedly connected between the bottom of the slider 14 and the inner bottom of the slide groove 13. A mounting frame 16 is fixedly connected to the front side wall of the slider 14, and a screening net 17 is provided in the mounting frame 16. Through the arrangement of the extrusion mechanism and the screening mechanism, the eccentric wheel 4 can be driven to rotate repeatedly through the drive of the servo motor 6 and the transmission of the transmission belt 3, and the mounting frame 16 and the screening net 17 can be squeezed. The elastic force of the first spring 15 can drive them to vibrate slightly up and down, which can improve the screening rate while preventing sand and gravel of appropriate size from being stuck in the screening net 17.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] In the utility model, when the staff uses the utility model, the staff starts the servo motor 6 and adds the sand and gravel raw materials into the shell 1 through the feed pipe 2. The start of the servo motor 6 will drive the first crushing roller 7 and the first gear ring 8 to rotate. The rotation of the first gear ring 8 will drive the second gear ring 12 meshing therewith to rotate. The rotation of the second gear ring 12 will drive the second crushing roller 11 to rotate, so that the second crushing roller 11 and the first crushing roller 7 rotate in both directions, and the sand and gravel passing therethrough can be crushed. The drive of the servo motor 6 will drive the first transmission wheel 9 to rotate. The first transmission wheel 9 drives the connecting rod 5 and the connecting rod 5 and the eccentric wheel 4 to rotate through the transmission of the transmission belt 3. When When the eccentric wheel 4 rotates downward, the end of the eccentric wheel 4 will squeeze the mounting frame 16, and the mounting frame 16 will drive the screening net 17 to move downward. When the eccentric wheel 4 rotates upward to reset, the mounting frame 16 is no longer squeezed by the eccentric wheel 4, and the mounting frame 16 will reset upward through the elastic force of the first spring 15 and the displacement of the slide slot 13, and repeat this process with a small amplitude and a high frequency, so that the screening net 17 can vibrate up and down, which can prevent sand and gravel of moderate size from being stuck in the screening net 17, and can improve the screening efficiency of large sand and gravel, so as to screen sand and gravel of different sizes for the production of concrete of different specifications, and the setting of the conical baffle 18 can effectively prevent sand and gravel from being stuck in the corners of the shell 1, so as to facilitate its collection.
