Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction machinery equipment, and particularly relates to a multi-directional rotary mixing and conveying device and method for composite mortar. BACKGROUND

[0002] Composite mortar is a new type of building material made by mixing cement, sand, additives and high molecular polymers in a scientific ratio. In the preparation of ordinary concrete, cement and sand (also known as fine aggregate or fine aggregate) are usually mixed first to form a dry mixed mixture, then an appropriate amount of water is gradually added while stirring until the mixture reaches the desired consistency and uniformity, and finally, gravel (also known as coarse aggregate or coarse aggregate) and pebbles (or other types of aggregate) are added as needed to enhance the strength and durability of the concrete.

[0003] At present, the mixing and conveying of mortar are generally realized by using a screw conveyor.

Detailed Implementation

[0035] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] For a multi-directional rotary mixing and conveying device for composite mortar, please refer to... Figures 1-5The system includes a base 1, a material trough 2 connected to the top of the base 1, a screw conveyor shaft 3 rotatably connected inside the material trough 2, a motor I 4 mounted on the rear side of the material trough 2, the output shaft of the motor I 4 connected to the screw conveyor shaft 3, a mounting frame 5 mounted on the rear top of the base 1, a mixing mechanism mounted on the mounting frame 5, the mixing mechanism including two left and right material cylinders 61 connected to the upper part of the mounting frame 5, a feed bin 62 mounted on the upper part of the two material cylinders 61 facing away from each other, a discharge bin 63 mounted on the front bottom of the material cylinders 61, a rotating shaft 64 rotatably connected to the middle of the material cylinders 61, four stirring plates 65 circumferentially spaced on the rotating shaft 64, the stirring plates 65 located inside the material cylinders 61, a through groove 69 opened on the side of the stirring plates 65 near the rotating shaft 64, and a drive assembly for driving the rotating shaft 64 to rotate at the top of the mounting frame 5, the drive assembly including a rotating component connected to the mounting frame. 5. Two large bevel gears 67 are located at the top center of the mounting frame 5. A motor II 66 is installed on the rear side of the top of the mounting frame 5. The output shaft of the motor II 66 is connected to the large bevel gear 67 on the rear side. Small bevel gears 68 are connected to the ends of two rotating shafts 64 that are close to each other. The small bevel gears 68 are located between the two large bevel gears 67 and mesh with the large bevel gears 67. An arc-shaped baffle 7 for blocking the top feed inlet of the discharge bin 63 is slidably connected to the upper part. The arc-shaped baffle 7 is in contact with the outer wall of the material cylinder 61. The top of the mounting frame 5 is provided with a pushing assembly for pushing the arc-shaped baffle 7 to slide up and down. The pushing assembly includes a motor III 81 installed on the front side of the top of the mounting frame 5. A large gear 82 is connected to the output shaft of the motor III 81. Arc-shaped racks 83 are connected to the two arc-shaped baffles 7. The arc-shaped racks 83 mesh with the large gears 82 and are in contact with the outer wall of the material cylinder 61.

[0037] Initially, the right-side arc-shaped baffle 7 is closed to block the right-side discharge hopper 63, while the left-side arc-shaped baffle 7 is open. Cement and sand are fed into the right-side material cylinder 61. The control motor II 66 drives the large bevel gear 67 connected to it to rotate alternately in both directions, which in turn drives the small bevel gear 68 to drive the rotating shaft 64 to rotate the mixing plate 65 alternately in both directions. This mixes the cement and sand in the material cylinder 61, achieving the purpose of pre-mixing and preparing a dry-mixed cement and sand mixture. This achieves the effect of pre-mixing and uniformly mixing cement and sand, thereby improving the quality of the composite mortar. The control motor Ⅲ81 drives the large gear 82 to rotate, which pushes the right arc-shaped rack 83 upward and the left arc-shaped rack 83 downward. This causes the right arc-shaped baffle 7 to move upward and open, while the left arc-shaped baffle 7 moves downward and closes, so that the mixture prepared in the right material cylinder 61 is fed into the material trough 2 through the discharge bin 63. At the same time, crushed stone and water are added into the material trough 2. The motor Ⅰ4 drives the screw conveyor shaft 3 to rotate, so as to stir and mix the mixture of crushed stone, water, cement and sand to realize the preparation of composite mortar. The rotation of the screw conveyor shaft 3 can also send the prepared composite mortar forward from the material trough 2. While the prepared mixture in the right-side cylinder 61 is being fed into the trough 2, cement and sand are simultaneously fed into the left-side cylinder 61. Control motor III 81 drives the large gear 82 in reverse, pushing the right-side arc-shaped rack 83 downwards and the left-side arc-shaped rack 83 upwards. This causes the right-side arc-shaped baffle 7 to move downwards and close, while the left-side arc-shaped baffle 7 moves upwards and opens, allowing the prepared mixture in the left-side cylinder 61 to be fed into the trough 2. This alternating premixing of cement and sand between the two cylinders 61 ensures the continuous pre-mixing of the dry-mixed cement and sand mixture, thereby ensuring the continuous preparation and delivery of composite mortar and improving work efficiency. After the arc-shaped baffle 7 moves upwards and opens, the mixing plate 65 rotates in both directions, pushing the dry-mixed cement and sand mixture in the cylinder 61 into the discharge hopper 63 to prevent the mixture from remaining in the cylinder 61.

[0038] Please refer to Figure 6 The base 1 has a separation mechanism on the top rear side. The separation mechanism includes two support plates 91 connected to the top rear side of the base 1. The support plates 91 are located in front of the material cylinder 61. A hopper 92 is installed between the tops of the two support plates 91. A screen plate 93 that can move up and down is slidably connected inside the hopper 92 through a sliding rod. The front and rear sides of the top of the hopper 92 are connected to the spray pipe 95 through connecting plates 94.

[0039] Crushed stone is fed into hopper 92, and the dispersed crushed stone falls into trough 2 through mesh plate 93. Crushed stone with clumps of soil adhering to it is blocked by mesh plate 93. A liquid delivery device is connected to nozzle 95, and water is introduced into nozzle 95 and sprayed into hopper 92 through nozzle 95 to wash away the crushed stone with clumps of soil adhering to mesh plate 93. This causes the clumps of crushed stone to disperse and fall into trough 2, where it is mixed with the pre-mixed cement and sand mixture. This makes the mixture of crushed stone, cement and sand more uniform, thereby further improving the quality of composite mortar.

[0040] Please refer to Figures 6-8 The hopper 92 is equipped with a pushing mechanism for pushing the screen plate 93 to vibrate up and down. The pushing mechanism includes a U-shaped push plate 102 and a guide rod 103. The rear side of the hopper 92 is slidably connected to the U-shaped push plate 102, which can move back and forth, through the guide rod 103. A spring 104 connects the U-shaped push plate 102 and the guide rod 103. The top left and right sides of the U-shaped push plate 102 are both inclined surfaces with a higher front and a lower rear. The top left and right sides of the screen plate 93 are connected to lifting plates 101. The lifting plates 101 are composed of an inverted U-shaped sliding plate and a contact rod. The inverted U-shaped sliding plate is connected to the top of the screen plate 93 and slides with the hopper 92. The contact rod is connected to the lower part of the outer wall of the inverted U-shaped connecting plate 94 and contacts the top of the U-shaped push plate 102. The rear side of the U-shaped push plate 102 is connected to a U-shaped pull plate 1. 05. Each of the two rotating shafts 64 is connected to a pusher frame 106 on one side close to each other. The pusher frame 106 includes a disc 1061 connected to the rotating shaft 64. Eight connecting plates 1062 are connected to the disc 1061 at circumferential intervals. A pusher block 1063 that can rotate up and down is hinged to the side of the connecting plate 1062 away from the disc 1061. The pusher block 1063 can contact the U-shaped pull plate 105 as the connecting plate 1062 rotates. An L-shaped support block 1064 for supporting the pusher block 1063 is connected to the side of the connecting plate 1062 away from the disc 1061. The pusher block 1063 is located inside the L-shaped support block 1064. The corners of the pusher block 1063 that are in contact with the inner wall of the L-shaped support block 1064 are rounded, while the corners of the pusher block 1063 that are not in contact with the inner wall of the L-shaped support block 1064 are right angles.

[0041] Due to the engagement of the large bevel gear 67 and the small bevel gear 68, the two rotating shafts 64 rotate in opposite directions, causing the two push frames 106 to rotate in opposite directions as well. That is, when the left push frame 106 rotates clockwise, the right push frame 106 rotates counterclockwise, and vice versa. Since the corners where the push block 1063 contacts the inner wall of the L-shaped support block 1064 are rounded, while the corners where the push block 1063 does not contact the inner wall of the L-shaped support block 1064 are right angles, after the push block 1063 on the push frame 106 rotates clockwise and contacts the U-shaped pull plate 105, the push block 1063 is supported by the L-shaped support block 1064 and cannot move forward or upward. The push block 1063 rotates and pushes the U-shaped pull plate 105 backward, thereby pulling the U-shaped push plate 102 backward. The spring 104 is compressed. When the push block 1063 rotates to disengage from the U-shaped pull plate 105, the U-shaped push plate 102 pulls the U-shaped pull plate 105 forward to reset under the reset action of the spring 104. The push block 1063 on the push frame 106 reverses and contacts the U-shaped pull plate 105. The push block 1063 continues to rotate and is pushed by the U-shaped pull plate 105 to flip backward and upward. When the push block 1063 passes the U-shaped pull plate 105, the push block 1063 rotates downward to reset under the action of gravity. The alternating forward and reverse rotation of the two pushers 106 allows the U-shaped pusher 102 to move back and forth continuously. When the U-shaped pusher 102 moves backward, it pushes the lifting plate 101, which in turn moves the mesh plate 93 upward through its inclined surface. When the U-shaped pusher 102 moves forward, the mesh plate 93 and the lifting plate 101 move downward under the action of gravity, which causes the mesh plate 93 to shake up and down. This, in turn, causes the gravel on the mesh plate 93 to shake up and down, helping to disperse the gravel and prevent the mesh plate 93 from becoming clogged.

[0042] Please refer to Figure 9 The base 1 has a support 11 on its lower side. Two hydraulic rods 12 are installed on the left and right sides of the support 11. An inverted U-shaped plate 13 is connected to the telescopic rod of the hydraulic rod 12. The inverted U-shaped plate 13 is fixedly connected to the base 1.

[0043] By extending the telescopic rod of the hydraulic rod 12, the inverted U-shaped plate 13 can be pushed to move the base 1 upward, thereby raising the material trough 2 to a suitable height, and then conveying the mortar to a suitable height so that subsequent vehicles can receive the mortar.

[0044] Please refer to Figure 10 The feed hopper 62 is slidably connected to a baffle 14 that can be pulled upwards. The baffle 14 has an opening at the top so that a hand can be inserted to pull the baffle 14 upwards. A pull rope 15 is connected to the top of the baffle 14 and is connected to the outer wall of the feed cylinder 61.

[0045] The baffle 14 can seal the feed hopper 62 to prevent material from overflowing from the feed hopper 62 when the dry mixture of cement and sand is prepared in advance. The baffle 14 can be pulled out of the feed hopper 62 by the pull rope 15 so that the baffle 14 can be removed and inserted back into the feed hopper 62 later.

[0046] A method for mixing and conveying composite mortar using multi-directional rotary mixing includes the following steps:

[0047] S1. Feeding: Cement and sand are fed into the material cylinder 61.

[0048] S2. Pre-mix the dry mixture of cement and sand, and control the motor II 66 to drive the large bevel gear 67 connected to it to rotate alternately in both directions, so that the small bevel gear 68 drives the rotating shaft 64 to drive the mixing plate 65 to rotate alternately in both directions. The alternating rotation of the mixing plate 65 stirs and mixes the cement and sand in the material cylinder 61.

[0049] S3. Unloading: Control motor Ⅲ81 drives the large gear 82 to rotate, thereby pushing the arc rack 83 to move the arc baffle 7 upward and open, so as to put the prepared mixture in the material cylinder 61 into the material trough 2.

[0050] S4. To prepare composite mortar, crushed stone and water are put into the material trough 2. The motor I4 is controlled to drive the screw conveyor shaft 3 to rotate, so as to stir and mix the mixture of crushed stone, water, cement and sand to prepare composite mortar.

[0051] S5, conveying composite mortar, the spiral conveyor shaft 3 rotates to send the prepared composite mortar forward from the material trough 2.

[0052] The above description merely illustrates preferred embodiments of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
