Technical Field
[0001] This utility model relates to the field of concrete production equipment technology, specifically to a concrete mixing device that can accurately measure concrete. Background Technology
[0002] Concrete is an indispensable basic material in building construction and infrastructure development. Its quality directly affects the safety and durability of buildings. To ensure concrete quality, it is essential to strictly control the proportions of its ingredients (such as cement, sand, gravel, and water) and ensure uniform mixing. While traditional concrete mixing equipment can perform basic mixing tasks, its metering accuracy is insufficient, leading to unstable concrete quality.
[0003] Traditional concrete mixing plants typically use manual or semi-automatic methods to weigh and transport raw materials, which has the following problems: low weighing accuracy: manual weighing is prone to errors, affecting concrete quality; low efficiency: the raw material transportation and mixing process depends on manual operation, resulting in low production efficiency; complex structure: existing equipment usually contains a large number of high-precision components, resulting in high manufacturing costs and difficult maintenance.
[0004] Therefore, there is an urgent need to design a concrete mixing device that can accurately measure concrete to solve the problems of low weighing accuracy, low efficiency and complex structure of existing technologies. Utility Model Content

[0008] Specifically, the collection bin is divided into multiple independent chambers by vertical partitions. Each independent chamber has a discharge port at the bottom and a baffle on the discharge port. The bottom of the collection bin is also equipped with a guide trough with a funnel-shaped cross-section, and the lower end of the guide trough extends directly above the inlet of the weighing hopper.
[0009] Specifically, the weighing hopper is provided with a feed inlet at the top, and the four corners of the weighing hopper are connected to the support frame through suspension arms. Each support arm is provided with a weighing sensor, which is symmetrically installed between the outer wall of the weighing hopper and the suspension arm.

Detailed Implementation
[0016] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0017] like Figure 1As shown, a concrete mixing device capable of precise measurement includes a support frame 1, an aggregate bin 2, a weighing hopper, a conveying pipe 4, and a mixing host 5. The support frame 1 includes an upper platform 1.1, a middle platform 1.2, and a lower base 1.3. The aggregate bin 2 is fixedly installed on the upper platform 1.1. The weighing hopper is installed below the middle platform 1.2 via a suspension arm 3.1. One end of the conveying pipe 4 is connected to the weighing hopper, and the other end of the conveying pipe 4 extends above the mixing host 5. The mixing host 5 is fixedly installed on the lower base 1.3.
[0018] The support frame 1 is welded together and fixed. The support frame 1 is placed on a plane to ensure stability. The support frame 1 includes an upper platform 1.1, a middle platform 1.2 and a lower base 1.3. The upper platform 1.1 is used to fix the collection bin 2, the middle platform 1.2 is used to fix and connect the weighing hopper, and the lower base 1.3 is used to fix and place the mixing host 5.
[0019] The aggregate bin 2 is fixed on the upper platform 1.1. The aggregate bin 2 is used to store the raw materials to be mixed into concrete. The aggregate bin 2 is equipped with a vertical partition plate, which divides the aggregate bin 2 into several independent chambers. Each independent chamber has a discharge port 2.1 at the bottom. The discharge port 2.1 is equipped with a baffle. The discharge port 2.1 and the baffle plate are used to open and close the baffle plate to discharge the corresponding material as needed. The lower part of the aggregate bin 2 is also equipped with a guide chute 2.2, which is used to collect the material from the discharge port 2.1 and transport it directly above the inlet of the weighing hopper.
[0020] The weighing hopper is located on the middle platform 1.2. The four corners of the weighing hopper are connected to the middle platform 1.2 by the suspension arms 3.1. A weighing sensor 3.2 is installed between the suspension arms 3.1 and the weighing hopper. The weighing sensor 3.2 is used to weigh the material inside the weighing hopper. The bottom of the weighing hopper is equipped with a discharge door 3.4. The discharge door 3.4 is controlled by an operating lever 3.3. The discharge door 3.4 and the operating lever 3.3 are connected by a linkage mechanism. After the weighing is completed, the discharge door 3.4 is opened by the operating lever 3.3 to discharge the material.
[0021] The load cell 3.2 is a resistance strain gauge sensor with a rated load of 500 kg, accuracy class C3, protection class IP67, and output signal of 0-20 mV / V (refer to industry-standard models such as HBM PW15A or Mettler Toledo Z6FCA). The load cells 3.2 are symmetrically installed, with four load cells symmetrically distributed at the weighing hopper support points. Each sensor is fixed to the suspension assembly with bolts. The load cell signals are connected in parallel, with the excitation voltage input terminals of all sensors connected in parallel and powered by the same power supply. The load cell signals are also superimposed in series, with the output signal lines of each sensor connected in series. The millivolt-level voltage signals output by each sensor are directly superimposed through a junction box. The load cell signals are processed uniformly, and the superimposed total signal is transmitted to the weighing instrument through a shielded cable. The instrument's built-in A / D conversion module converts the analog signal into a digital signal, directly displaying the total weight value.
[0022] One end of the conveying pipe 4 is connected to the discharge gate 3.4 of the weighing hopper, and the other end of the conveying pipe 4 is connected to the feed inlet of the mixing host 5. The conveying pipe 4 is used to discharge the weighed material into the mixing host 5. The conveying pipe 4 is a soft telescopic pipe and will not provide additional gravity or support to the weighing hopper. A support frame 4.1 is provided on the conveying pipe 4. The upper end of the support frame 4.1 is a ring structure fixed in the middle of the conveying pipe 4, and the bottom of the support frame 4.1 is fixed on the lower base 1.3. The mixing host 5 is also fixed on the lower base 1.3. The mixing host 5 is used to mix and stir the weighed material to form qualified concrete.
