A cement mortar formwork compaction process and formwork equipment

Abstract

This invention relates to a cement mortar demolding and compaction process and equipment. The cement mortar demolding and compaction process includes the following steps: 1) Filling two storage chambers of the distribution hopper with cement mortar evenly in one go, wherein the volume of each storage chamber is half the total volume of the mold cavity; 2) Transferring the cement mortar from one storage chamber to the mold and compacting the mold once, then transferring the cement mortar from the other storage chamber to the compacted mold and compacting it a second time. The two storage chambers in the distribution hopper have equal volumes, each half the total volume of the mold cavity, allowing the cement mortar filled evenly in one go to be directly divided into two equal portions without the need for complex operations such as weighing. This separate transfer method ensures that the amount of cement mortar transferred to the mold each time is half of the required total, providing accurate raw material quantity for the subsequent compaction process and guaranteeing the compaction effect.

Description

Technical Field

[0001] This invention generally relates to the technical field of sample preparation for testing. More specifically, this invention relates to a cement mortar molding and compaction process and molding equipment. Background Technology

[0002] In the preparation of cement mortar test blocks, the raw materials are first processed into a slurry state using a mixing device. At this point, the cement mortar exists in an irregular form within the mixing pot. The traditional process involves manually transferring the mortar from the mixing pot to the cavity of a three-piece mold (test mold) using a scraper, followed by compaction. Compaction is performed twice, with half of the raw material being transferred to the mold each time. These two manual transfers are commonly referred to as "molding." Existing technologies also utilize equipment for molding, such as the split-type cement mortar test mold disclosed in Chinese Utility Model Patent No. CN216707839U. This design features a forming cover and a hopper above the mold. During use, the cement mortar is poured into the hopper and falls smoothly into the mold. Simultaneously, the movement of the forming cover scrapes away excess cement mortar from the top of the mold.

[0003] In existing technologies, whether the cement mortar is transferred manually or dropped into the mold using equipment, the amount of cement mortar transferred into the cavity of the triple mold cannot be accurately measured in actual operation. Even if the total amount of cement mortar is determined, it is impossible to accurately divide the cement mortar into two equal halves, which does not meet national testing standards and cannot provide accurate raw material quantity for the next step of the compaction process, thus affecting the compaction effect. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a cement mortar drop molding and compaction process to solve the technical problem in the prior art of being unable to accurately control the amount of cement mortar dropped into the mold in a single run. Another purpose of this invention is to provide a cement mortar drop molding device to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the cement mortar formwork compaction process provided in the first aspect of the present invention adopts the following technical solution: A cement mortar formwork compaction process includes the following steps:

[0006] 1) Fill the two storage chambers of the material distribution hopper with cement mortar evenly at one time, wherein the volume of each storage chamber is half of the total volume of the test mold cavity;

[0007] 2) Transfer the cement mortar from one of the storage chambers to the mold and compact the mold once. Then transfer the cement mortar from the other storage chamber to the mold after compaction and compact it a second time.

[0008] The beneficial effects are: the two storage chambers in the distribution hopper have equal volumes, each half the total volume of the mold cavity, allowing the cement mortar, once filled evenly, to be directly divided into two equal portions without the need for complex operations such as weighing. This separate transfer method ensures that the amount of cement mortar transferred to the mold each time is half of the required total, providing accurate raw material quantities for the subsequent compaction process and guaranteeing the compaction effect.

[0009] As a further improvement, the two storage chamber groups are arranged horizontally at intervals. In step 1), after filling the two storage chamber groups of the distribution hopper with cement mortar all at once, excess cement mortar is scraped off with a scraper along the top surface of the distribution hopper to ensure that the storage chamber groups are evenly filled with cement mortar. The scraping method is relatively simple and easy to automate.

[0010] The cement mortar formwork removal device provided in the second aspect of the present invention adopts the following technical solution: A cement mortar formwork removal device, comprising:

[0011] frame;

[0012] The material distribution hopper is located on the frame. The material distribution hopper has two horizontally spaced groups of discharge holes, and each group of discharge holes includes three discharge holes arranged in sequence.

[0013] The movable partition structure is used to close the bottom opening of each blanking hole and cooperate with the two blanking hole groups to form two storage cavity groups. The volume of each storage cavity group is half of the total volume of the trial mold cavity. The movable partition structure is also used to open the bottom opening of the blanking hole to blank the trial mold.

[0014] The beneficial effects are as follows: The movable partition structure can cooperate with the distribution hopper to form two storage chamber groups. Both storage chamber groups have equal volumes, each representing half of the total volume of the mold cavity. This allows for the direct and equal division of a single, evenly filled batch of cement mortar into two portions, eliminating the need for complex operations such as weighing. The movable partition structure also allows cement mortar from one of the storage chamber groups to be individually deposited into the mold, ensuring that the amount transferred to the mold each time is half of the required total. This provides an accurate amount of raw material for the subsequent compaction process, guaranteeing effective compaction.

[0015] As a further improvement, the movable partition structure includes two movable partitions corresponding one-to-one with the two sets of material discharge holes. Each movable partition can independently close and open its corresponding set of material discharge holes. Each set of material discharge holes is closed and opened individually. Whether closing or opening the set of material discharge holes, the travel distance of the movable partition is short, resulting in a shorter material discharge time and improved operating speed.

[0016] As a further improvement, the cement mortar casting equipment includes a mold positioning structure for horizontally positioning the mold, which is located below the material distribution hopper. This positioning structure ensures accurate horizontal positioning of the mold, preventing cement mortar leakage caused by misalignment of the mold with the storage chamber assembly.

[0017] As a further improvement, the cement mortar formwork dropping equipment includes a formwork dropping support platform mounted on the frame, and the material distribution hopper and movable partition structure are both mounted on the formwork dropping support platform;

[0018] At least one of the mold-dropping support platform and the mold-testing positioning structure is slidably mounted on the frame in the horizontal direction, so that the mold-dropping support platform and the mold-testing positioning structure can slide relatively horizontally. The ability of the mold-dropping support platform and the mold-testing positioning structure to slide relatively horizontally makes it convenient for robots or manuals to place and remove molds from the mold-testing positioning structure, without interference or influence from the mold-dropping support platform.

[0019] As a further improvement, the sliding direction of the mold dropping support platform and / or the mold trial positioning structure is perpendicular to the spacing direction of the two storage cavity groups. By sliding the mold dropping support platform and the mold trial positioning structure a shorter distance, the operation time can be shortened.

[0020] As a further improvement, the cement mortar casting equipment also includes a mold lifting mechanism. This mechanism drives the mold positioning structure to rise and approach the distribution hopper during casting, and also drives the mold positioning structure to descend after casting is complete. The mold lifting mechanism ensures that the mold is as close as possible to the distribution hopper during casting, preventing cement mortar leakage.

[0021] As a further improvement, the mold positioning structure includes corner positioning blocks for corresponding and positioning each corner of the mold. Each corner positioning block ensures horizontal positioning and prevents horizontal movement.

[0022] As a further improvement, the top of the distribution hopper is provided with a funnel that is wider at the top and narrower at the bottom, with the opening at the bottom of the funnel corresponding to the distribution hopper. The funnel facilitates the pouring of cement mortar into the distribution hopper. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0036] The cement mortar casting device of the present invention uses two storage chambers arranged side by side on the material distribution hopper to store cement mortar. The volume of each storage chamber is half of the total volume of the test mold cavity. By first transferring the cement mortar from one storage chamber and then compacting it once, and then transferring the cement mortar from the other storage chamber and compacting it a second time, the accuracy of the amount of cement mortar transferred in a single transaction can be guaranteed, which is beneficial to ensuring the effect of subsequent compaction.

[0037] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0038] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0039] Example 1 of the cement mortar casting equipment provided by the present invention:

[0040] like Figures 1 to 9 As shown, the cement mortar formwork dropping equipment mainly includes a frame 100, a dropping section 200, and a test mold positioning structure 300.

[0041] The frame 100 provides an installation platform for the entire process flow, including the wiring layout for water, electricity, and gas, as well as the positioning and locking functions for each component. The mold dropping section 200 and the trial mold positioning structure 300 are both mounted on the frame 100. For example... Figure 1 As shown, a mixing pot placement platform 400 and a mold cover plate placement platform 500 are arranged on the frame 100. The mixing pot placement platform 400 is used to place the mixing pot 600, and the mold cover plate placement platform 500 is used to place the mold cover plate. The mixing pot placement platform 400 and the mold cover plate placement platform 500 are located beside the mold positioning structure 300 and the mold dropping section 200.

[0042] like Figures 1 to 6 As shown, the die-casting section 200 includes a guide rail 201 on one side and a linear module 214 on the other side. For ease of description, the extension direction of the guide rail 201 is defined as the front-to-back direction, and the linear module 214 and the guide rail 201 are arranged at intervals in the left-to-right direction. It should be noted that the left-to-right and front-to-back directions are only relative concepts and do not limit the overall structural layout and usage of the equipment. Figure 1 As shown, there is a certain distance between the guide rail 201, the linear module 214, and the top surface of the frame 100, that is, the guide rail 201 and the linear module 214 are spaced apart on the top of the frame 100. Here, two rows of left and right support columns 202 are fixedly installed on the top surface of the frame 100, and the guide rail 201 and the linear module 214 are installed on the support columns 202, thus forming a gap with the frame 100 in the vertical direction. The purpose of forming the gap is to accommodate the trial mold 800 and the trial mold positioning structure 300. Supporting the guide rail 201 and the linear module 214 with the support columns 202 can prevent water or other debris on the frame 100 from entering the guide rail 201 and the linear module 214 and affecting the normal sliding of the mold dropping sliding platform 203.

[0043] The die-dropping section 200 includes a die-dropping sliding platform 203 slidably mounted on guide rails 201 and linear module 214. The assembly method with guide rails 201 is conventional and will not be detailed here. For example, a slider can be fixed on the die-dropping sliding platform 203, and the slider cooperates with the guide rails 201. The other side of the die-dropping sliding platform 203 is mounted on the linear output end of the linear module 214, and the linear module 214 drives the die-dropping sliding platform 203 to slide back and forth. The die-dropping sliding platform 203 serves as the mounting carrier for the material distribution hopper 204, movable partition 205, and partition cylinder 206. Of course, in other embodiments, to achieve support and sliding of the die-dropping sliding platform, two guide rails spaced apart can be provided, the die-dropping sliding platform is slidably mounted on the guide rails, and a cylinder or other structure can be provided on the die-dropping sliding platform to drive it to slide back and forth.

[0044] A cable chain is also connected to the mold-dropping sliding platform 203. The other end of the cable chain is connected to the frame 100. The cable chain provides protection for the routing of air pipes, cables, etc.

[0045] A material distribution hopper 204 is fixedly installed on the mold dropping sliding platform 203. The structure of the material distribution hopper 204 is as follows: Figure 6 As shown, the material distribution hopper 204 here is actually a six-unit mold. The hopper 204 has two sets of discharge holes arranged alternately on the left and right sides. Each set of discharge holes includes three discharge holes 207 arranged sequentially on the left and right sides. After the discharge holes 207 are closed by a movable partition 205, they form a storage cavity for storing cement mortar, thus forming two storage cavity sets. The volume of each storage cavity is 40*160*20mm, while the size of the standard test block is 40*160*40mm. That is, the sum of the volumes of the two storage cavity sets is equal to the volume of three standard test blocks. Since the test mold 800 is a three-unit mold, the volume of a single storage cavity set is equal to half the volume of the test mold 800 cavity.

[0046] like Figure 6As shown, a clearance groove 208 is provided at the bottom center of the distribution hopper 204. The clearance groove 208 is used to avoid the movable partition 205. Large-diameter bolt holes 209 are provided on the edge of the distribution hopper 204. In use, bolts are passed through the bolt holes 209 to fix the distribution hopper 204 onto the mold-dropping sliding platform 203. A smaller-diameter threaded hole 210 is also provided on the inner side of the bolt holes 209 on the distribution hopper 204. The threaded hole is used to install the funnel 212.

[0047] A sealing ring mounting groove 211 is also provided around the six material discharge holes 207 on the top surface of the material distribution hopper 204. When in use, the sealing ring is placed in the sealing ring mounting groove 211 and pressed on by the funnel 212 to achieve a seal between the material distribution hopper 204 and the funnel 212.

[0048] Correspondingly, the die-dropping sliding platform 203 is provided with a dropping channel corresponding to each dropping hole 207.

[0049] like Figure 2 and Figure 5 As shown, the movable partition 205 is slidably supported on the die-dropping sliding platform 203 in the left-right direction. There are two movable partitions 205, each corresponding to a set of blanking holes 207. Each of the two movable partitions 205 moves independently, capable of closing two sets of blanking holes individually. The die-dropping sliding platform 203 is also equipped with partition cylinders 206, with two cylinders 206 arranged corresponding to each movable partition 205. The two cylinders 206 are connected to the movable partition 205 via connecting rods 213 extending forward and backward. That is, connecting rods 213 are fixed to one end of the movable partition 205, and the partition cylinders 206 are connected to the front and rear ends of the connecting rods 213. By having the two cylinders 206 jointly push the movable partition 205 to move left and right reciprocatingly, the smoothness of the movement of the movable partition 205 is improved, preventing jamming.

[0050] like Figure 2 As shown, a funnel 212 is fixedly installed on the top of the distributing hopper 204. The funnel 212 has a structure that is wider at the top and narrower at the bottom, with a larger opening at the top. The bottom opening of the funnel 212 is directly opposite the distributing hopper 204, facilitating the entry of cement mortar from the mixing pot 600 into the distributing hopper 204. The funnel 212 is specifically installed on the distributing hopper 204 by bolt connection, and a sealing ring is used to achieve a seal.

[0051] like Figure 1 , Figure 3 and Figure 5 As shown, the trial mold positioning structure 300 is located below the mold dropping sliding platform 203. Two trial mold positioning structures 300 are arranged sequentially along the left-right direction, and each of the two trial mold positioning structures 300 corresponds one-to-one with one of the two blanking hole groups. The structure of the trial mold positioning structure 300 is as follows: Figure 9 As shown, the mold positioning structure 300 includes a mounting base 301 and four corner positioning blocks 302 fixed on the mounting base 301. Each corner positioning block 302 has two mutually perpendicular positioning surfaces, and the four corner positioning blocks 302 correspond one-to-one with the four corners of the mold 800. In use, a robot places the mold 800 on the mounting base 301 and positions it horizontally using the corner positioning blocks 302. Support columns 303 are also installed on the mounting base 301, with multiple support columns 303 arranged at intervals. The mold 800 is supported and placed on the support columns 303.

[0052] In this embodiment, the mold positioning structure 300 is movable and can be raised and lowered. Specifically, a lifting cylinder 700 is fixedly installed on the frame 100. The lifting cylinder 700 is connected to the mold positioning structure 300 and drives the mold positioning structure 300 to rise and fall. Before the movable partition 205 opens the bottom opening of the discharge hole 207 for material discharge, the lifting cylinder 700 lifts the mold positioning structure 300 and the mold 800, reducing the distance between the mold 800 and the discharge hole 207, which helps the cement mortar to fall more accurately into the mold cavity of the mold 800. There are two lifting cylinders 700, each corresponding to one of the two mold positioning structures 300.

[0053] To prevent the mold 800 from wobbling horizontally during material receiving, which could lead to cement mortar leakage, two positioning posts 304 are fixed on each mold positioning structure 300. Positioning holes are provided on the mold dropping sliding platform 203 corresponding to each positioning post 304. When the mold positioning structure 300 is driven upward by the lifting cylinder 700, the positioning posts 304 are inserted into the positioning holes. The cooperation between the positioning posts 304 and the positioning holes prevents the mold positioning structure 300 and the mold 800 from wobbling horizontally during material dropping. Alternatively, in other embodiments, positioning posts can be provided on the mold dropping sliding platform, and positioning holes can be provided on the mold positioning structure, achieving the same fitting and horizontal positioning of the mold.

[0054] like Figure 1As shown, a cleaning mechanism 900 is also fixedly installed on the frame 100. The function of the cleaning mechanism 900 is to clean the cement mortar remaining on the material distribution hopper 204 and movable partition 205 after the mold is removed. This cement mortar will affect the next experiment after it hardens, so it needs to be rinsed clean in time. The cleaning mechanism 900 and the mold positioning structure 300 are arranged sequentially in the front-back direction, that is, they do not overlap in the front-back direction. When the mold removal sliding platform 203 moves to the mold positioning structure 300, the mold is removed, and at this time the mold removal sliding platform 203 is in the mold removal position; when the mold removal sliding platform 203 moves to the cleaning mechanism 900, the mold removal sliding platform 203 is cleaned, and at this time the mold removal sliding platform 203 is in the cleaning position. An opening is provided on the frame 100 corresponding to the position of the cleaning mechanism 900, and a waste water tank is arranged below the opening.

[0055] The structure of the cleaning mechanism 900 is as follows Figure 7 and Figure 8 As shown, the cleaning mechanism 900 includes a cleaning mechanism mounting frame 901, which is fixedly mounted on the frame 100. A downward pressure cylinder 902 is fixed on the cleaning mechanism mounting frame 901. The top of the downward pressure cylinder 902 is fixed on the cleaning mechanism mounting frame 901, and a mounting plate 903 is fixed on the telescopic end at the bottom. A cleaning nozzle 904 and a drying nozzle 905 are mounted on the mounting plate 903. The number and arrangement of the cleaning nozzles 904 and the drying nozzles 905 can be arranged according to the cleaning and drying requirements. Guide posts 906 are fixed at the four corners of the mounting plate 903. A guide plate 907 is also fixed on the cleaning mechanism mounting frame 901, located above the mounting plate 903. A guide sleeve is fixed on the guide plate 907 corresponding to each guide post 906. Through the cooperation of the guide posts 906 and the guide sleeves, the mounting plate 903 can be guided. A shield 908 is also installed on the cleaning mechanism mounting bracket 901 to shield the structure such as the downward pressure cylinder 902.

[0056] The working steps of this invention are as follows:

[0057] 1) The robot places the trial mold 800 on the trial mold positioning structure 300 on the left side;

[0058] 2) The mold-dropping sliding platform 203 moves to the mold-dropping station, and the partition cylinder 206 drives the movable partition 205 to remain in the position of closing the material drop hole 207. The material distribution hopper 204 cooperates with the movable partition 205 to form a storage cavity.

[0059] 3) The robot pours the raw materials from the mixing pot 600 into the dispensing hopper 204, and uses a scraper to scrape off the excess raw materials along the top surface of the dispensing hopper 204, so that the raw materials are level and fill the storage cavity.

[0060] 4) The partition cylinder 206 drives the movable partition 205 on the left to open, and the raw material in the storage cavity group on the left falls into the test mold 800, completing the first mold drop. Before the mold drop, the lifting cylinder 700 drives the test mold positioning structure 300 and the test mold 800 on the left to rise.

[0061] 5) The lifting cylinder 700 drives the test mold 800 to descend, and the mold dropping sliding platform 203 slides away from the test mold 800. The robot takes away the test mold 800 and performs a vibration compaction on the test mold 800 after the first mold dropping.

[0062] 6) The robot places the compacted test mold 800 onto the test mold positioning structure 300 on the right side;

[0063] 7) The partition cylinder 206 drives the right movable partition 205 to open, and the raw material in the right storage cavity group falls into the test mold 800 after one vibration, completing the second mold drop. Before the mold drop, the lifting cylinder 700 drives the right test mold positioning structure 300 and the test mold 800 to rise.

[0064] 8) The lifting cylinder 700 drives the test mold 800 to descend, and the mold dropping sliding platform 203 slides away from the test mold 800. The robot takes away the test mold 800 and performs a second vibration on the test mold 800 after the second mold dropping.

[0065] 9) The mold-dropping sliding platform 203 moves to the cleaning station for cleaning and drying. During cleaning, the pressing cylinder 902 carries the mounting plate 903 down and presses it on the top of the funnel 212, forming a sealed space together with the funnel 212. This prevents debris from spreading outwards during cleaning.

[0066] 10) Repeat steps 1) through 9).

[0067] In this embodiment, the two movable partitions 205 together form a movable partition structure, which is used to close and open the material discharge hole group. The mold dropping sliding platform 203 constitutes a mold dropping support platform that supports the material distribution hopper 204, the movable partitions 205, and the partition cylinder 206. The lifting cylinder 700 constitutes a mold lifting mechanism that can drive the mold positioning structure 300 to rise and fall. In other embodiments, the mold lifting mechanism can be a structure such as an electric actuator.

[0068] It should be noted that, Figure 1 , Figure 3 , Figure 4 , Figure 5 The diagram shows two test molds 800, but in actual use, the test mold 800 is first placed on one of the test mold positioning structures 300, and after one vibration compaction, it is placed on the other test mold positioning structure 300.

[0069] Example 2 of the cement mortar casting equipment provided by the present invention:

[0070] The main difference between this embodiment and Embodiment 1 is that in Embodiment 1, each of the two material discharge hole groups has a corresponding movable partition, and the two movable partitions slide independently. In this embodiment, a single sliding movable partition is used to simultaneously close both material discharge hole groups. When it is necessary to open one of the material discharge hole groups, the movable partition slides a short distance to ensure that the other material discharge hole group remains closed.

[0071] Example 3 of the cement mortar casting equipment provided by the present invention:

[0072] The main difference between this embodiment and Embodiment 1 is that in Embodiment 1, the movable partition slides on the die-feeding support platform. In this embodiment, the movable partition can be rotatably installed at the bottom of the material distribution hopper, relying on rotation to close and open the bottom opening of the material dropping hole assembly.

[0073] Example 4 of the cement mortar casting equipment provided by the present invention:

[0074] The main difference between this embodiment and Embodiment 1 is that in Embodiment 1, the mold positioning structure includes corner positioning blocks that correspond one-to-one with each corner of the mold. In this embodiment, the mold positioning structure is provided with positioning grooves, and the mold is fitted into the positioning grooves. The positioning grooves can be formed by removing a portion from the mounting base, or by adding a surrounding plate to the mounting base.

[0075] Example 5 of the cement mortar casting equipment provided by the present invention:

[0076] The main difference between this embodiment and Example 1 is that in Example 1, the cement mortar casting equipment includes a mold lifting mechanism, which drives the mold positioning structure to rise and fall. In this embodiment, the mold positioning structure is fixed on the frame.

[0077] Example 6 of the cement mortar casting equipment provided by the present invention:

[0078] The main difference between this embodiment and Embodiment 1 is that in Embodiment 1, the mold dropping support platform is slidably mounted on the frame in the horizontal direction, the mold trial positioning structure is fixedly arranged relative to the frame, and the sliding direction of the mold dropping support platform is perpendicular to the spacing direction of the two blanking hole groups. In this embodiment, without considering cleaning, the mold dropping support platform is fixed on the frame in the horizontal direction, and the mold trial positioning structure is slidably mounted on the frame. Alternatively, both can be slidably mounted on the frame. In other embodiments, the sliding direction of the mold dropping support platform and / or the mold trial positioning structure can be consistent with the spacing direction of the two blanking hole groups. In this case, one of the mold trial positioning structures can be eliminated, and the storage cavity group corresponding to the mold trial positioning structure can be switched by the relative sliding of the mold dropping support platform and / or the mold trial positioning structure.

[0079] Example 7 of the cement mortar casting equipment provided by the present invention:

[0080] The main difference between this embodiment and Example 1 is that in Example 1, the cement mortar casting equipment includes a mold positioning structure. In this embodiment, the mold positioning structure is omitted, and in actual use, a robot can be used to hold the mold in place, while the casting support platform can still slide back and forth.

[0081] Example 1 of the cement mortar drop molding and vibration compaction process provided by the present invention:

[0082] The cement mortar formwork compaction process in this embodiment is the same as the process flow in Embodiment 1 of the cement mortar formwork equipment described above, and will not be repeated here.

[0083] Example 2 of the cement mortar drop molding and vibration compaction process provided by the present invention:

[0084] The main difference between this embodiment and Example 1 is that in Example 1, after filling the storage chamber with cement mortar, excess cement mortar is scraped off with a scraper along the top surface of the distribution hopper, ensuring the storage chamber is evenly filled with cement mortar. In this embodiment, a push-pull plate is installed on the top of the distribution hopper. The push plate is pulled out when filling with cement mortar, and pushed back in after filling, blocking excess cement mortar above the push plate.

[0085] Example 3 of the cement mortar drop molding and vibration compaction process provided by the present invention:

[0086] The main difference between this embodiment and Embodiment 1 is that in Embodiment 1, the storage cavity is formed by the material discharge hole on the hopper and the movable partition at the bottom. In this embodiment, a bottom-closed groove is provided on the hopper to form the storage cavity. In this case, when transferring cement mortar, it is necessary to close the top of one of the storage cavity groups before pouring.
