Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a high-efficiency production device for machine-made sand concrete. Background Art

[0002] With the improvement of people's environmental awareness and the need to reduce the damage to natural resources, the use of natural sand has been strictly restricted and will gradually withdraw from the building materials market and be replaced by machine-made sand. Machine-made sand is a fine aggregate in concrete and refers to mechanically crushed rock particles with a particle size of less than 4.75 mm.

[0003] Among them, announcement number CN217292835U discloses an efficient production device for machine-made sand concrete, including a base and a production box, the top surface of the base is installed with the production box through a mounting column, and the side wall surface of the production box is provided with a feed port, the top surface of the base is inclinedly provided with a support frame, the side wall surface of the support frame is provided with a groove, and the interior of the groove is provided with a screw rod. In the utility model, during use, by starting the drive motor, the drive motor drives the screw rod to rotate, and under the mutual cooperation of the screw rod and the threaded sleeve, the loading box is driven to move up and down along the support frame. When the loading box moves to the top of the feed port of the production box, the discharge port of the loading box is opened, and the raw materials in the loading box can fall from the discharge port into the production box. The utility model has a simple structure and is easy to operate, which is convenient for the staff to transport the raw materials on the ground into the production box, greatly improving the convenience of use of the device.

[0004] During use, the device sprays water into the interior through the sprinkler head to reduce dust inside the feeding box. However, when the sand and gravel inside the feeding box are put into the production box, dust will still be generated, and the production box will also generate a large amount of dust in the process of crushing the sand and gravel. These dusts can easily spread outward from the inside of the feed port, causing dust pollution.

[0005] Therefore, it is necessary to invent a high-efficiency production device for machine-made sand concrete to solve the above problems. Utility Model Content

[0032] Among them, the feeder 5 transports the sand and gravel to the inside of the feed tray 4, and then the sand and gravel pass through the second feed hole 21, the third feed hole 22, and the first feed hole 13 in turn and are sent into the interior of the production box 1. During the loading process, the vacuum cleaner 11, the suction pipe 12, and the suction box 41 cooperate to suck the dust generated inside the feed tray 4.

[0033] See Figure 4 and Figure 5 The second feeding hole 21 is opened on the right surface of the feeding bin 2, and the right surface of the baffle plate 23 of the feeding bin 2 is rotatably connected near the upper end. The third feeding hole 22 is opened at the lower end of the feeding bin 2, and the third feeding hole 22 is connected to the first feeding hole 13. The flip plate 15 is arranged inside the first feeding hole 13, and the inside of the flip plate 15 is fixedly connected with a rotating shaft. The side wall of the first feeding hole 13 is provided with two groups of plug holes 14, and the front and rear ends of the rotating shaft are rotatably connected with the plug holes 14. The lower end of the flip plate 15 is fixedly connected with a counterweight plate 16. The front and rear inner walls of the feeding tray 4 are provided with mounting grooves 42 near the upper end, and the suction box 41 is fixedly connected to the mounting groove 42. The vacuum cleaner 11 is fixedly installed on the upper surface of the production box 1, and the left end of the suction pipe 12 is fixedly connected to the upper end of the vacuum cleaner 11. The right end of the suction pipe 12 passes through the front and rear surfaces of the feeding tray 4 and is fixedly connected to the suction box 41.

[0034] Specifically, during the feeding process, the sand and gravel slide toward the inside of the second feed hole 21 through the feed tray 4, and at the same time push the baffle 23 inward, thereby transporting the sand and gravel to the inside of the feed bin 2. At the same time, the sand and gravel inside the feed bin 2 presses the left side of the flip plate 15 downward, thereby sending the sand and gravel into the interior of the production box 1.

[0035] In addition, when the feeding is stopped for production, the flip plate 15 automatically resets to a horizontal state under the action of the counterweight plate 16, sealing the first feed hole 13. At the same time, the shielding plate 23 automatically resets to seal the second feed hole 21, thereby effectively preventing the dust from spreading to the outside during the production process, and can automatically open and close the first feed hole 13 and the second feed hole 21, thereby improving the convenience of use.

[0036] The working principle of the present invention is as follows: in order to prevent dust from spreading outward during the production process, the first feed hole 13 is sealed by the flip plate 15, and the second feed hole 21 is sealed by the shielding plate 23, thereby effectively preventing dust from spreading outward. At the same time, during the loading process, the vacuum cleaner 11, the suction pipe 12, and the suction box 41 cooperate to suck the dust generated inside the feed tray 4, further improving the environmental protection level of the production process.
