[0002] When making precast beams, it is necessary to first prepare the concrete raw materials for casting the precast beams in a certain proportion, which requires the use of a concrete mixing device.

[0003] Existing technologies often use proportioning devices with fixed chamber capacity, where the proportioning ratio is controlled by a conveying mechanism (or metering valve). For example, patent document CN220280068U discloses a concrete proportioning device, including: a main assembly placed on the ground; an anti-deviation assembly including a base plate, fastening bolts for fixing the base plate, a fixing frame connected to the base plate, a chute formed on the base plate and the fixing frame, and rotating wheels rotatably connected in the chute; several sets of anti-deviation components are symmetrically distributed on the main assembly; and a recovery assembly for recovering concrete raw materials adhering to the main assembly. This concrete proportioning device, by symmetrically installing multiple sets of rotating wheels on both sides of a fixed conveyor belt, fixes the belt within a certain range, preventing belt deviation during conveying, improving work efficiency, and avoiding safety accidents.

[0004] Based on the above search and combined with existing technology, it was found that the actual volume of the raw material silo in existing proportioning devices is fixed, and the proportioning is mainly achieved by sensors. However, as precision components, sensors may experience data fluctuations, or even data errors or damage due to environmental influences, resulting in inaccurate or incorrect proportioning ratios. Therefore, there is a need for a concrete proportioning device. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] refer to Figures 1-3 The concrete proportioning device shown includes a fixed frame 1 and a batching box 2 fixed on the fixed frame 1. A batching trough 21 is provided on the batching box 2, which is vertically penetrating the batching box 2. A discharge gate 22 is hinged to the bottom of the batching box 2 to close the lower opening of the batching trough 21.

[0030] Several sliding partitions 3 are slidably embedded in the mixing tank 21. The several sliding partitions 3 are distributed in parallel in the horizontal direction in the mixing tank 21. The front and rear sides of the several sliding partitions 3 are slidably pressed against the inner walls of the front and rear sides of the mixing tank 21. The lower ends of the several sliding partitions 3 are slidably pressed against the upper surface of the unloading gate 22.

[0031] The left and right sides of the mixing box 2 are also fixed with adjusting drive components 4 for driving several sliding partitions 3 to slide horizontally along the mixing trough 21. The side wall of the mixing box 2 is fixed with a support frame 8. The fixed end of the adjusting drive component 4 is fixed on the support frame 8. The movable end of the adjusting drive component 4 slides through the mixing box 2 and is fixed to the side wall of another sliding lug 31.

[0032] A drive unit 6 for driving the unloading gate 22 to open and close is rotatably connected to the fixed frame 1. The fixed end of the drive unit 6 is rotatably connected to the fixed frame 1, and the movable end of the drive unit 6 is rotatably connected to the bottom surface of the unloading gate 22.

[0033] Based on the above structure, several sliding partitions 3 divide the batching tank 21 into multiple receiving tanks with different proportions. By simply putting the predetermined raw materials into the receiving tanks of the predetermined proportion, the proportioning of precast beam concrete raw materials can be completed. Compared with the proportioning method of existing technologies that rely on sensors and fixed compartments, this concrete proportioning device uses physical division to control the proportioning ratio. It flexibly utilizes the compartments with changeable volumes to achieve the proportioning purpose, making it more flexible to use. Moreover, the mechanical proportioning control is more reliable, which can improve the accuracy and reliability of the proportioning and achieve better results.

[0034] It should be noted that in this application, both the adjustment drive 4 and the opening / closing drive 6 are electric push rods (e.g., Figure 1 , Figure 3 As shown in the figure, those skilled in the art may also select other driving components that can achieve the same driving effect according to actual usage needs, which will not be elaborated here.

[0035] Furthermore, the upper end of the mixing box 2 is provided with a sliding groove 23, the sliding partition 3 is a vertical plate, and the top of the sliding partition 3 is integrally formed with a sliding ear 31 that is slidably embedded in the sliding groove 23;

[0036] The bottom of the sliding partition 3 is detachably connected to a sealing strip 35. The lower end of the sealing strip 35 is integrally formed with multiple longitudinally extending sealing ribs 351. The lower ends of the multiple sealing ribs 351 slide and abut against the upper surface of the unloading gate 22.

[0037] By setting the sealing strip 35, the contact area between the sliding partition 3 and the unloading gate 22 can be reduced, and multiple sealed chambers can be formed to ensure the sealing effect, reduce the possibility of concrete raw materials in each container tank seeping into each other from the bottom, ensure the accuracy of the mix ratio, and further reduce the wear on the unloading gate 22 and extend its service life.

[0038] Furthermore, a sealing groove 33 is provided at the bottom of the sliding partition 3, and a sealing ring 37 that is adapted to the sealing groove 33 is fixed at the top of the sealing strip 35. The sealing ring 37 is embedded in the sealing groove 33 and is press-fitted with the inner wall of the sealing groove 33, which enhances the sealing performance between the sealing strip 35 and the sliding partition 3, reduces the possibility of concrete raw materials seeping from the joint, and ensures the partition effect.

[0039] The bottom surface of the sliding partition 3 is also provided with screw holes 34, and a stepped hole 352 corresponding to the position of the screw hole 34 is provided between the multiple sealing ribs 351 of the sealing strip 35. A connecting bolt 36 is rotatably embedded in the stepped hole 352, and the upper end of the connecting bolt 36 is screwed into the screw hole 34.

[0040] The detachable design facilitates the installation and removal of the sealing strip 35, making it easy to replace when the sealing strip 35 is severely worn or damaged, and facilitating subsequent maintenance.

[0041] Furthermore, two slid grooves 23 are provided and located on the front and rear sides of the mixing box 2 respectively. Two sliding ears 31 are also provided and are slidably embedded in the two slid grooves 23 respectively. A guide rod 5 is fixed in one of the slid grooves 23, and a sliding hole 32 is provided on one of the sliding ears 31 for the guide rod 5 to slide through, so as to make the sliding partition 3 more stable when sliding.

[0042] Example 2

[0043] refer to Figure 4 The concrete proportioning device shown differs from that in Example 1 in that:

[0044] The upper end of the ingredient box 2 is provided with a sliding groove 23, the sliding partition 3 is a vertical plate, and the top of the sliding partition 3 is integrally formed with a sliding lug 31 that is slidably embedded in the sliding groove 23.

[0045] A sealing frame 7 is detachably fixed to the periphery of the sliding partition 3. The outer side of the sealing frame 7 is integrally formed with multiple protruding ribs 71 that abut against the front and rear side walls of the feeding trough 21 and the upper surface of the unloading gate 22. The sealing frame 7 is fixed to the sliding partition 3 by fixing bolts 72.

[0046] By setting the sealing frame 7, the friction between the sides of the sliding partition 3 and the side wall of the feeding trough 21 and the unloading door 22 can be reduced more comprehensively, while ensuring the sealing effect. The detachable design also facilitates subsequent maintenance and improves the performance.

[0047] The working principle of this utility model is as follows: In daily use, when mixing concrete for precast beams, the operator only needs to open the adjusting drive 4 according to the required configuration ratio, so that the adjusting drive 4 drives several sliding partitions 3 to slide respectively, dividing the mixing trough 21 into multiple receiving troughs with different ratios. Then, the predetermined raw materials are put into the receiving troughs of the predetermined ratio to complete the mixing of precast beam concrete raw materials. Finally, the opening and closing drive 6 is activated to open the unloading door 22, so that the mixed raw materials can be output, thus completing the mixing operation of precast beam concrete raw materials.

[0048] Compared to existing technologies that rely on sensors and fixed compartments for proportioning, this concrete proportioning device uses physical segmentation to control the proportioning ratio. It flexibly utilizes compartments with variable volumes to achieve the proportioning purpose, making it more flexible to use. Furthermore, the mechanical proportioning control is more reliable, improving the accuracy and reliability of the proportioning and resulting in better performance.

[0049] It should be further noted that the technical features of the adjustment drive and opening / closing drive (both of which are electric push rods) involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
