DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] See also Figure 1-4 , an embodiment provided by the utility model:
[0022] A concrete proportioning device for PCCP pipe production, comprising:
[0023] The device body includes a box 100:
[0024] A top box 110 is fixedly installed on the top of the box body 100, and a first feed port 111 and a second feed port 112 are fixedly installed on the top of the top box 110, respectively. Rotating shafts are installed on the tops of the first feed port 111 and the second feed port 112, respectively, and a top cover is installed on the outside of the rotating shaft. A water tank 113 is installed on the top of the box body 100, and a water inlet and outlet are installed on the outside of the water tank 113. A water pump is provided inside the water tank 113, and a water pipe 114 is installed inside the water tank 113. One side of the water pipe 114 passes through the top of the top box 110, and a nozzle 115 is installed at the bottom of the water pipe 114. Guide plates 119 are fixedly installed on both sides of the inner wall of the top box 110, and the guide plates 119 are respectively located below the first feed port 111 and the second feed port 112. The box body 1 00 is movably installed with a first motor 116 on the outside, a stirring shaft 117 is fixedly installed on the outside of the first motor 116, a stirring blade 118 is installed on the outside of the stirring shaft 117, and a plurality of through grooves are opened on the outer surface of the stirring blade 118. A filter screen 120 is installed on the inner wall of the top box 110. Sand and gravel are poured into the first feeding port 111 and the second feeding port 112 respectively, and then enter the filter screen 120 for screening and then enter the box body 100. The first motor 116 is turned on to make the stirring blade 118 drive the mixing of the internal materials. The filter screen 120 can select the large pieces of sand and gravel mixed in the sand and gravel, and then remove them, which saves the trouble and labor of manual selection in the early stage. At the same time, the through grooves of the stirring blade 118 can stir the materials more evenly.
[0025] Furthermore, the middle part of the stirring shaft 117 is connected to an auger 126 through a rotating connecting piece 124, a protective cover 125 is installed on the outer side of the rotating connecting piece 124, the auger 126 is located in the inner cavity of the discharge port 127, and a valve is provided inside the discharge port 127. The rotating connecting piece 124 is used to drive the auger 126 to stir the material when discharging, thereby avoiding the accumulation of mixed materials. At the same time, the auger 126 is used to accelerate the overall discharge speed during the discharge process.
[0026] Furthermore, a base 130 is fixedly installed around the bottom of the box body 100, a sleeve 132 is arranged below the base 130, and a shock absorbing assembly is arranged inside the sleeve 132 near the bottom of the base 130, and the shock absorbing assembly is composed of a shock absorbing spring and a damper 131.
[0027] Furthermore, fixed sleeves 128 are fixedly installed on both sides of the stirring shaft 117, and L-shaped scrapers 129 are fixedly installed on both sides of the fixed sleeve 128. The L-shaped scraper 129 fits against the inner wall of the box body 100. The fixed sleeve 128 and the L-shaped scraper 129 prevent the material from sticking to the inside of the box body 100 for a long time and causing agglomeration.
[0028] Furthermore, slide grooves are provided on both sides of the inner wall of the top box 110, and sliders are slidably installed on the slide grooves. The sliders are fixedly installed on both sides of the filter screen 120, and the installation and removal of the filter screen 120 are facilitated by the slide groove sliders.
[0029] Furthermore, a second motor 123 is movably installed on the outer side of the top box 110, a connecting column 122 is fixedly installed on the outer side of the second motor 123, a metal leaf 121 is fixedly installed on the outer side of the connecting column 122, and the metal leaf 121 is located directly below the filter 120. By turning on the second motor 123, the metal leaf 121 is driven to rotate. Since the metal leaf 121 is in contact with the filter 120, vibration is generated through collision, thereby accelerating the shaking off of the material on the filter 120.
[0030] Working principle: When in use, sand and gravel are poured into the first feed port 111 and the second feed port 112 respectively, enter the filter screen 120 for screening and then enter the box body 100, turn on the first motor 116 to make the stirring blade 118 drive the mixing of the internal materials, and the filter screen 120 can select the large pieces of sand and gravel mixed in the sand and gravel, thereby removing them, eliminating the need for manual selection in the early stage and saving trouble and labor. At the same time, the through groove of the stirring blade 118 plays a role in stirring the materials more evenly, and the rotating connecting piece 124 is used to drive the auger 126 to stir the materials when discharging, so as to avoid the accumulation of mixed materials. At the same time, the auger 126 is used to accelerate the overall discharging speed during the discharge process, and the second motor 123 is turned on to drive the metal leaf 121 to rotate. Because the metal leaf 121 is in contact with the filter screen 120, vibration is generated through collision, thereby accelerating the shaking off of the material on the filter screen 120.
