Description

Technical Field

[0001] This invention relates to the technical field of concrete mixing and feeding devices, specifically an intermittent feeding device for mixing building concrete. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates and water in a certain proportion. It is widely used in civil engineering.

[0003] Currently, when mixing concrete, a certain amount of aggregate needs to be put into the mixer. However, due to the inconsistent size of the aggregate, and the fact that most feeding devices do not have a screening device for the aggregate, the addition of a large number of large aggregate particles can easily affect the quality of the produced concrete and make it inconvenient for daily use. In order to solve the above problems, the inventor proposes an intermittent feeding device for building concrete mixing. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: As Figure 1-9As shown, the present invention provides an intermittent feeding device for mixing building concrete, including a mixing mechanism 1. A screening mechanism 2 is provided on the upper surface of the mixing mechanism 1 for screening stones. A shaking mechanism 3 is provided on the upper surface of the mixing mechanism 1 for driving the screening box 202 to shake, thereby screening the stones. The shaking mechanism 3 is located on both sides of the screening mechanism 2. A crushing mechanism 4 is provided on the upper surface of the mixing mechanism 1 and the side of the screening mechanism 2 for crushing unqualified stones. A transport mechanism 5 is provided on the side of the crushing mechanism 4 away from the screening mechanism 2 for transporting the crushed stones.

[0031] The stirring mechanism 1 includes a stirring tank 101. A rotating rod 104 is rotatably mounted inside the stirring tank 101. A first side gear 105 is fixedly mounted on the outer surface of the upper end of the rotating rod 104. A second side gear 106 is rotatably mounted inside the stirring tank 101. A rotating rod 107 is fixedly mounted on the lower surface of the second side gear 106, and the rotation of the rotating rod 104 passes through the second side gear 106 and the rotating rod 107. A spur gear 110 is rotatably mounted inside the stirring tank 101, and the spur gear 110 meshes with the first side gear 105 and the second side gear 106. A mounting box 102 is fixedly mounted on the upper surface of the stirring tank 101. A first motor 103 is fixedly mounted inside the mounting box 102, and the bottom center of the first motor 103 is fixedly connected to the rotating rod 104. Several stirring rods 108 are fixedly mounted on the outer surfaces of the rotating rod 104 and the rotating rod 107. A scraper 1 is fixedly mounted on the end of the stirring rod 108 away from the rotating rod 104. 09. The scraper 109 is located on the side away from the mixing rod 108 and contacts the inner wall of the mixing tank 101 to drive the mixing rod 108 to rotate. In use, the first motor 103 is turned on to drive the rotating rod 104 to rotate. The rotation of the rotating rod 104 drives the first side gear 105 to rotate. The rotation of the first side gear 105 drives the sprocket 110 to rotate. The rotation of the sprocket 110 drives the second side gear 106 to rotate. The rotation of the second side gear 106 drives the rotating rod 107 to rotate. The rotation of the rotating rod 104 and the rotating rod 107 drives the mixing rod 108 to rotate. At this time, the rotation directions of the rotating rod 104 and the rotating rod 107 are opposite, thereby driving the two sets of mixing rods 108 to rotate in opposite directions, making the mixing more uniform. Then, the rotation of the mixing rod 108 drives the scraper 109 to rotate. The rotation of the scraper 109 scrapes off the concrete adhering to the inner wall of the mixing tank 101 to avoid waste.

[0032] By adopting the above technical solution, the No. 1 motor 103 can drive the stirring rod 108 to rotate.

[0033] A movable plate 116 is slidably installed inside the mixing tank 101. Sliding strips 117 are fixedly installed on both sides of the movable plate 116, and the sliding strips 117 are slidably disposed inside the mixing tank 101. A toothed plate 118 is fixedly installed on the side of the movable plate 116. A connecting rod 111 is fixedly installed on the side of the spur gear 110 away from the rotating rod 104. A first bevel gear 112 is fixedly installed at the center of the end of the connecting rod 111 away from the spur gear 110. A half gear 115 is rotatably installed inside the mixing tank 101, and the half gear 115 and the toothed plate 118 are in movable meshing. A first fixed rod 114 is fixedly installed on the side of the half gear 115 near the connecting rod 111. A second bevel gear 113 is fixedly installed at the center of the end of the first fixed rod 114 away from the half gear 115. The second bevel gear 113 meshes with the first bevel gear 112. Two first springs 119 are fixedly installed on the side of the movable plate 116 near the toothed plate 118. The end furthest from the moving plate 116 is fixedly connected inside the mixing tank 101 to drive the moving plate 116 to move. In use, the rotation of the spur gear 110 drives the rotation of the connecting rod 111, which in turn drives the rotation of the first bevel gear 112, which in turn drives the rotation of the second bevel gear 113, which in turn drives the rotation of the first fixed rod 114, which in turn drives the rotation of the half gear 115. When the half gear 115 meshes with the toothed plate 118, the rotation of the half gear 115 drives the toothed plate 118 to move, which in turn drives the moving plate 116 to move. At this time, the first spring 119 extends under the influence of external force. When the half gear 115 and the toothed plate 118 are not meshed, the first spring 119 contracts when the external force disappears, driving the moving plate 116 to move and return it to its original position.

[0034] By adopting the above technical solution, the spherical gear 110 can drive the moving plate 116 to move.

In use, the shaking of the mounting block 307 drives the connecting plate 308 to shake. When the connecting plate 308 shakes, it drives the fixed plate 203 to shake, and the shaking of the fixed plate 203 drives the screening box 202 to shake.

[0038] By adopting the above technical solution, the mounting block 307 can drive the screening box 202 to shake.

[0049] Working principle: First, the power rod 405 is rotated to drive the first bevel gear 406 to rotate. The rotation of the first bevel gear 406 drives the second bevel gear 407 to rotate. The rotation of the second bevel gear 407 drives the bidirectional screw 408 to rotate. The rotation of the bidirectional screw 408 drives the limiting block 404 to move. The movement of the limiting block 404 drives the fixing block 403 to move. The movement of the fixing block 403 drives the crushing roller 402 to move. The distance between the crushing rollers 402 is adjusted according to the size of the qualified stones. After the adjustment is completed, the power rod 405 is stopped.

[0050] Next, the stones are introduced into the screening box 201. The second motor 311 is turned on to drive the third bevel gear 312 to rotate. The rotation of the third bevel gear 312 drives the fourth bevel gear 313 to rotate. The rotation of the fourth bevel gear 313 drives the mounting rod 309 to rotate. The rotation of the mounting rod 309 drives the semi-circular disk 310 to rotate. The rotation of the semi-circular disk 310 drives the mounting block 307 to shake. The shaking of the mounting block 307 drives the connecting plate 308 to shake. When the shaking of the connecting plate 308 drives the fixing plate 203 to shake, the shaking of the fixing plate 203 drives the screening box 202 to shake. The shaking of the screening box 202 screens the stones, and the unqualified stones move during the shaking process, moving into the crushing box 401. At this time, the qualified stones fall downward and move into the mixing tank 101.

[0051] Then, the first motor 103 is turned on, driving the rotating rod 104 to rotate. The rotation of the rotating rod 104 drives the first side gear 105 to rotate, which in turn drives the sprocket 110 to rotate. The sprocket 110 then drives the second side gear 106 to rotate, which in turn drives the rotating rod 107 to rotate. The rotation of the rotating rods 104 and 107 drives the stirring rod 108 to rotate. At this time, the rotating rods 104 and 107 rotate in opposite directions, thus causing the two sets of stirring rods 108 to rotate in opposite directions, making the mixing more uniform. The rotation of the stirring rods 108 then drives the scraper 109 to rotate, scraping away the concrete adhering to the inner wall of the mixing drum 101 to avoid waste. Simultaneously, the rotation of the sprocket 110 drives the connecting rod 111 to rotate... The rotation of connecting rod 111 drives the first bevel gear 112 to rotate, which in turn drives the second bevel gear 113 to rotate, which in turn drives the first fixed rod 114 to rotate, which in turn drives the half gear 115 to rotate. When the half gear 115 meshes with the toothed plate 118, the rotation of the half gear 115 drives the toothed plate 118 to move, which in turn drives the moving plate 116 to move. At this time, the first spring 119 extends under the influence of external force. When the half gear 115 and the toothed plate 118 are not meshed, the first spring 119 contracts when the external force disappears, driving the moving plate 116 to move and return it to its original position. Through the indirect movement of the moving plate 116, the inlet is opened indirectly, thereby allowing the stones to be fed indirectly.

[0052] Finally, motor 410 is activated, driving the third bevel gear 413 to rotate. The rotation of the third bevel gear 413 drives the fourth bevel gear 414 to rotate, which in turn drives the second fixed rod 415 to rotate. The rotation of the second fixed rod 415 drives the limiting strip 418 to rotate, which in turn drives the fifth bevel gear 416 to rotate. The rotation of the fifth bevel gear 416 drives the sixth bevel gear 417 to rotate, which in turn drives the crushing roller 402 to rotate. The crushing roller 402 crushes the substandard stones, and the crushed stones slide into the transport box 501. At this point, motor 410 drives pulley 411 to rotate. The rotation of the first pulley 411 drives the connecting belt 412 to move, which in turn drives the second pulley 507 to move. The movement of the second pulley 507 drives the transmission rod 506 to rotate, which in turn drives the sixth bevel gear 505 to rotate. The rotation of the sixth bevel gear 505 drives the fifth bevel gear 504 to rotate, which in turn drives the screw rod 502 to rotate. The screw rod 502 moves the crushed stones into the connecting pipe 503. Due to the inclined tube of the connecting pipe 503, the crushed stones move through the connecting pipe 503 into the screening box 201 for re-screening.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
