[0013] Preferably, the feeding mechanism comprises a transmission gear ring fixedly installed at the top end of the feeding shaft cylinder, and the right side of the transmission gear ring is engagedly connected with a driving gear rotatably installed at the upper end of the feeding tank body, and the driving gear drives the transmission gear ring and the feeding shaft cylinder to rotate, drives the bottom end of the feeding support to rotate to the discharge slot hole at different angles, and after moving, the discharge slot hole is opened by abutting against the sealing cone block to realize the proportioning feeding.

[0014] Preferably, the feeding mechanism comprises a spiral sleeve fixedly installed between adjacent proportioning partitions, and the inside of the spiral sleeve is screw-connected to the upper end of the feeding shaft, and the bottom end of the feeding shaft is rotatably connected to the middle part of the top end of the sealing cone block, and the sealing cone block drives the feeding shaft to rise and rotate.

[0015] Preferably, the inside of the bottom of the feeding tank body is provided with a mixing mechanism, and the mixing mechanism comprises a mixing shaft rotatably arranged in the inside of the feeding tank body through a bearing, and the upper end of the mixing shaft is rotatably arranged at the inside center position of the proportioning partition through a bearing, and the upper end of the mixing shaft extends to the inside upper part of the feeding tank body.

[0017] A feeding method of a proportioning feeding device for preparing a polycarboxylic acid water reducing agent comprises the following steps: S1: Different types of materials are fed through the feeding channel in the inside upper part of the feeding tank body, and the different types of materials are fed between adjacent proportioning partitions, and the multiple types of materials are stored and separated by the proportioning bottom disc at the bottom of the proportioning partition, so that they are selectively fed in the subsequent proportioning process; S2: The motor at the top of the feeding tank body drives the driving gear to engage the transmission gear ring, the transmission gear ring drives the inside feeding shaft cylinder to rotate in the inside of the proportioning partition, and the bottom end of the telescopic slide rod and the feeding support are driven by the feeding shaft cylinder to rotate on the bottom surface of the proportioning bottom disc, so as to drive the feeding support to rotate to the inside of the discharge slot hole to be opened for opening the feeding; S3: The pressure supply pump at the top of the feeding tank body supplies pressure to the oil pressure pipeline, so that the telescopic part of the hydraulic telescopic device is extended, and the feeding support fixedly connected to the outer end of the telescopic slide rod is driven by the hydraulic telescopic device to slide outward, so as to press the bottom end inclined surface of the sealing cone block through the feeding support to drive it to slide upward, and the opened discharge slot hole feeds the different types of materials stored in the inside downward; S4: The sealing cone block inside the mixing chassis drives the upper feeding shaft to move synchronously. The spiral sleeve connected to the feeding shaft through the threaded groove is pulled, so that the feeding shaft rotates during the upward process, which helps to guide the material between adjacent mixing partitions and avoids blockage during the feeding process, thus affecting the efficiency of feeding and mixing. S5: Multiple materials are fed downwards into the feeding tank. The mixing shaft inside the feeding tank is driven to rotate by the motor at the top. The mixing shaft drives the mixing branches and the inclined scraper set at equal angles below to rotate inside the feeding tank. The mixing branches mix the multiple materials, and the rotation of the inclined scraper avoids material residue inside the feeding tank and improves the efficiency of proportioning and feeding.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the proportioning and feeding equipment and method for preparing polycarboxylate superplasticizer, through the area separated by proportioning partitions inside the feeding tank body, stores multiple raw materials to facilitate proportioning and feeding under various needs. Simultaneously, the mixing branch below the feeding tank body and the inclined scraper assist in the proportioning and mixing of multiple raw materials, improving the preparation efficiency of polycarboxylate superplasticizer. The specific details are as follows: 1. The various raw materials of polycarboxylate superplasticizer are fed into the feeding channel with equal angles. After entering the feeding tank, they are stored in areas divided by adjacent proportioning partitions, thereby avoiding the mixing of the raw materials of polycarboxylate superplasticizer and affecting the subsequent proportioning and feeding.

[0019] Furthermore, the drive gear on the top of the feeding tank meshes with the transmission gear ring and the feeding shaft cylinder to rotate. The feeding shaft cylinder drives the telescopic slide rod and the feeding bracket to rotate to the feeding channel corresponding to different angles, thereby selecting raw materials stored in different areas for feeding.

[0020] 2. The pressure pump at the top of the feeding shaft cylinder supplies pressure to the interior of the hydraulic expansion joint through the oil pressure pipeline, causing the outer end of the hydraulic expansion joint to extend the telescopic slide rod, so that the telescopic slide rod drives the feeding bracket to slide outward, thereby squeezing the inclined surface of the corresponding sealing cone block, thereby driving the sealing cone block to slide upward and open the feeding slot hole, assisting the internally stored raw materials to be fed downward.

[0021] Furthermore, as the sealing cone rises, it drives the feeding shaft synchronously. The feeding shaft is guided by the upper spiral sleeve so that it rotates as it moves upward. The rotation of the feeding shaft guides and mixes the stored raw materials, thereby avoiding blockage during the proportioning and feeding process.

[0022] 3. The mixing shaft rotates inside the feeding tank, driving the mixing branches and inclined scrapers set at equal angles below to rotate. The mixing branches mix various materials, while the rotation of the inclined scrapers avoids material residue inside the feeding tank and improves the efficiency of proportioning and feeding.

After moving, the bracket 7 rises against the sealing cone block 10 to open the feeding slot 9 and realize the proportioned feeding.

[0030] The feeding mechanism includes a spiral sleeve 16 fixedly installed between adjacent proportioning partitions 4, and the inside of the spiral sleeve 16 is spirally connected to the upper end of the feeding shaft 17.
