It usually includes molds, concrete mixing equipment, conveying equipment, vibration equipment, etc. The concrete mixing equipment is used to mix materials such as cement, aggregate, sand and water according to the proportion to make the concrete required for casting components.
[0003] In order to ensure uniform mixing of concrete, the prior art adopts a batch mixing method, in which raw materials are put into the casting box in batches. However, the various raw materials first put into the casting box have been mixed evenly, while the subsequent raw materials are put in again without being mixed. This will make it difficult for the subsequent raw materials to be evenly mixed in the already mixed concrete. Moreover, this problem will become more serious as multiple additions are made, which will seriously prolong the mixing time of the concrete and reduce the quality of the concrete. Utility Model Content

In this solution, during the batch mixing process of concrete raw materials, the materials of subsequent batches are premixed before being put into mixing, so that the materials can be evenly mixed in advance. Then, when the subsequent batches of materials are put into mixing, the materials of the two batches can be more fully integrated together, which can effectively improve the quality of concrete production and thus improve the quality of precast components.
[0005] To this end, the technical solutions adopted are as follows:
[0006] A device for casting precast concrete components, comprising a mixing box, which is divided into a pre-mixing chamber and a production chamber by a baffle at the top and bottom; a rotating rod passing through the baffle is vertically arranged in the middle of the mixing box, and the rotating rod is driven to rotate by a driving device; a plurality of first stirring rods and second stirring rods are fixed on the rotating rod, and the first stirring rod and the second stirring rod are both arranged perpendicular to the rotating rod and are respectively located in the pre-mixing chamber and the production chamber; a feed hole is provided on the top of the mixing box, and a batching assembly is fixed above the feed hole; the pre-mixing chamber and the production chamber are separated by a baffle, and a plurality of discharge holes are provided on the baffle.
[0007] A further technical solution is that the premixing chamber and the production chamber are respectively connected to a first water inlet pipe and a second water inlet pipe.
[0008] A further technical solution is that the plurality of discharge holes are distributed on the baffle in an equidistant annular array, the lower portion of the baffle is rotatably connected to a limit plate, and the limit plate is provided with a plurality of limit holes matching the discharge holes.
[0009] A further technical solution is that a bracket is fixed under the baffle, a second driving device is installed on the bracket, a gear is fixed to the output end of the second driving device, and the outer edge of the limit plate has a gear ring meshing with the gear.
[0010] A further technical solution is that the baffle is arranged to be inclined toward its center.
[0011] A further technical solution is that the batching assembly includes a batching box fixed to the mixing box, and a plurality of vertically arranged storage holes are opened on the batching box. The bottom of the batching box is rotatably connected to a horizontally arranged rotating roller, and the rotating roller is driven to rotate by a driving device. The rotating roller is located directly above the feed hole.

DETAILED DESCRIPTION
[0024] The technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the present application.
[0025] As Figures 1-2 shown, a kind of concrete prefabricated component pouring device, including mixing box 1, the premixing cavity 2 and making cavity 3 are separated by baffle 100 in the mixing box 1 upper and lower, the middle part of the mixing box 1 is vertically provided with rotating rod 7 passing through baffle 100, the rotating rod 7 is rotated by a driving device one 12, the rotating rod 7 is fixed with several first stirring rod 8 and second stirring rod 9, the first stirring rod 8 and second stirring rod 9 are vertically arranged with rotating rod 7 and are located in premixing cavity 2 and making cavity 3 respectively, the top of the mixing box 1 is provided with feeding hole 11, the ingredient assembly 6 is fixed above feeding hole 11, the premixing cavity 2 and making cavity 3 are separated by a baffle 100 and baffle 100 is provided with multiple discharge holes 10.
[0026] Precast concrete component casting equipment is a device used to produce precast concrete components in factories or construction sites. It usually includes molds, concrete mixing equipment, conveying equipment, vibration equipment, etc. The concrete mixing equipment is used to mix materials such as cement, aggregate, sand and water according to a certain ratio to make the concrete required for casting the structure. During the mixing process, by adding materials such as cement, aggregate, sand and water in batches, the mixing process can be better controlled to ensure that each material is fully mixed and evenly, thereby obtaining a more uniform concrete.
[0027] In this solution, the user activates the driving device 12 to drive the rotating rod 7 to rotate, and the rotation of the rotating rod 7 can drive the first stirring rod 8 to rotate in the pre-mixing chamber 2, and the second stirring rod 9 to rotate in the production chamber 3. When in use, a variety of raw materials can be poured into the interior of the pre-mixing chamber 2 through the feed hole 11, and then stirred by the multiple first stirring rods 8 to pre-mix the raw materials. After the initial pre-mixing is completed, the raw materials enter the production chamber 3 through the multiple discharge holes 10 and are further mixed by the multiple second stirring rods 9. The user can continue to pour the next batch of raw materials into the pre-mixing chamber 2 for pre-mixing. The materials in the pre-mixing chamber 2 and the production chamber 3 can be stirred at the same time, compared to directly stirring the unmixed raw materials in batches.
[0028] This solution pre-mixes the subsequent batches of materials before they are put into mixing, which can make the materials evenly mixed in advance. Then, when the subsequent batches of materials are put into mixing, the two batches of materials can be more fully integrated together, which can effectively improve the quality of concrete production. Since the pre-mixing and final mixing are carried out simultaneously, the total mixing time will not be affected. Moreover, under the same mixing time, this solution can obtain concrete with more even mixing and better quality.
[0029] In this solution, a discharge pipe with an on / off function is installed at the bottom of the mixing box 1, which is connected to the production chamber 3 to facilitate the discharge of the finished concrete in the production chamber 3. The pre-mixing chamber 2 and the production chamber 3 are respectively connected to a first water inlet pipe 4 and a second water inlet pipe 5.
[0030] During the concrete mixing process, the user can connect the first water inlet pipe 4 and the second water inlet pipe 5 respectively through external water pipes, so as to add water to the premixing chamber 2 and the production chamber 3 respectively during the premixing and final mixing processes. During the process, the amount of water should be accurately controlled according to the requirements of the concrete design mix ratio. Too much or too little water will affect the performance of the concrete. It is usually recommended to add water in batches until the slump required by the design is reached.
[0031] like Figures 3-4As shown, multiple discharge holes 10 are distributed in an equidistant annular array on a baffle 100. A limit plate 13 is rotatably connected to the bottom of the baffle 100. The limit plate 13 is provided with multiple limit holes 14 that match the discharge holes 10. A bracket 15 is fixed below the baffle 100. A second drive unit 16 is mounted on the bracket 15. A gear 17 is fixed to the output end of the second drive unit 16. The outer edge of the limit plate 13 has a ring gear that meshes with the gear 17. The baffle 100 is tilted toward its center.
[0032] During the process of premixing raw materials inside the premixing chamber 2, the multiple limiting holes 14 on the limiting plate 13 are staggered with the multiple discharge holes 10 at the bottom end of the inner wall of the premixing chamber 2, thereby causing blockage of the multiple discharge holes 10 through the upper surface of the limiting plate 13. When the premixing is completed, the user starts the driving device 2 16 to drive the gear 17 to rotate, and the gear 17 drives the ring gear to rotate, thereby driving the limiting plate 13 to rotate, so that the multiple limiting holes 14 on the limiting plate 13 coincide with the multiple discharge holes 10 respectively. At this time, the material in the premixing chamber 2 can flow into the production chamber 3 through the discharge holes 10. The inclined setting of the bottom end of the inner wall of the premixing chamber 2 facilitates the flow of the material. When the material discharge is completed, the user starts the driving device 2 16 again, so that the limiting plate 13 closes the multiple discharge holes 10 again, so that the user can continue to put the next batch of materials into the premixing chamber 2.
[0033] like Figure 1 and Figure 5 As shown, the batching assembly 6 includes a batching box 61 fixed to the mixing box 1. The batching box 61 is provided with a plurality of vertically arranged storage holes 62. A horizontally arranged rotating roller 63 is rotatably connected to the bottom of the batching box 61. The rotating roller 63 is driven to rotate by a driving device 65 and is located directly above the feed hole 11. The rotating roller 63 is embedded in the bottom of the batching box 61 and has a plurality of batching grooves 64 above it that match the storage holes 62.
[0034] During the preparation of concrete, it is necessary to ensure the accuracy of the proportions of various raw materials, and to accurately weigh and add materials such as cement, aggregate, sand and water in strict accordance with the designed proportions to ensure the correct proportions of the concrete in order to obtain the concrete properties required by the design. In this solution, the user can add various raw materials into the corresponding multiple storage holes 62 respectively, and the raw materials in the multiple storage holes 62 will fall into the multiple batching troughs 64 respectively and fill them up. The capacity of the multiple batching troughs 64 is made in advance according to the proportion, and the proportion is consistent with the designed proportion of the concrete raw materials.
[0035] For example, raw materials A, B, C and D are added to the multiple storage holes 62 in sequence, and the ratio of A, B, C and D when making concrete should be 1:2:3:4, then the capacity ratio of the multiple batching troughs 64 in sequence is also 1:2:3:4. When the user starts the driving device three 65, the driving device three 65 drives the rotating roller 63 to rotate. When the rotating roller 63 rotates the open ends of the multiple batching troughs 64 to the bottom, the materials in the multiple batching troughs 64 fall and fall into the pre-mixing chamber 2 through the feed hole 11. With this arrangement, as the rotating roller 63 continues to rotate, it can be ensured that multiple materials are added to the pre-mixing chamber 2 in multiple times according to a fixed ratio, so as to achieve batch mixing of raw materials. By adjusting the rotation speed of the driving device three 65, the material feeding speed can be controlled to be consistent with the material stirring speed.
[0036] Working principle:
[0037] The user adds a variety of raw materials for making concrete into the corresponding multiple storage holes 62 respectively. The raw materials in the multiple storage holes 62 will fall into the multiple batching troughs 64 respectively and fill them. Then the user starts the driving device three 65, and the driving device three 65 drives the rotating roller 63 to rotate. When the rotating roller 63 rotates the open ends of the multiple batching troughs 64 to the bottom, the materials in the multiple batching troughs 64 fall and fall into the pre-mixing chamber 2 through the feed hole 11. As the rotating roller 63 continues to rotate, the multiple materials can be put into the pre-mixing chamber 2 in multiple times according to a fixed ratio.
[0038] After the material enters the premixing chamber 2, the user starts the driving device 12 to drive the rotating rod 7 to rotate, and the rotation of the rotating rod 7 drives multiple first stirring rods 8 to rotate in the premixing chamber 2, and multiple second stirring rods 9 to rotate in the production chamber 3. First, the multiple first stirring rods 8 stir the materials in the premixing chamber 2 and premix them. After completing the preliminary premixing, the user starts the driving device 2 16 to drive the gear 17 to rotate, and the gear 17 drives the ring gear to rotate, and then drives the limit plate 13 to rotate, so that the multiple limiting holes 14 on the limiting plate 13 coincide with the multiple discharge holes 10 respectively. At this time, the material in the premixing chamber 2 flows into the production chamber 3 through the discharge holes 10.
[0039] When the material discharge is completed, the user starts the driving device 2 16 again, so that the limit plate 13 closes the multiple discharge holes 10 again, and puts the next batch of materials into the pre-mixing chamber 2 through the batching component 6. After the pre-mixed raw materials enter the production chamber 3, they are further mixed by multiple second stirring rods 9. The materials in the pre-mixing chamber 2 and the production chamber 3 are stirred at the same time. During the stirring process, according to the requirements of the concrete design mix ratio, water is respectively injected into the pre-mixing chamber 2 and the production chamber 3 through the first water inlet pipe 4 and the second water inlet pipe 5.
[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
