Description

Technical Field

[0001] This utility model relates to the technical field of engineering mortar mixing equipment, and in particular to a weighing tool for self-mixed mortar on construction sites. Background Technology

[0002] Currently, most engineering mortar mixing still uses traditional electronic scales to measure material weight. While this method can meet basic weighing requirements to some extent, the small weight per weighing often necessitates multiple weighings to complete the measurement of all materials. This repetitive operation not only increases the labor intensity of workers but also slows down the entire mixing process, resulting in low efficiency. In the fast-paced, high-intensity work environment of construction sites, this inefficient weighing method clearly cannot meet the requirements of construction schedules. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a weighing tool for self-mixed mortar on construction sites that enables large-volume single-batch weighing, is highly efficient and labor-saving.

[0004] This utility model discloses a weighing tool for self-mixed mortar on construction sites, comprising: a support frame, which is independently and fixedly installed; a feed hopper, installed above the support frame, with a controllable discharge valve at its bottom; a collection box, installed at the bottom of the support frame, with an opening at its top; a conveying and weighing assembly, including a conveyor belt, a weighing roller, and a second drive motor, with both ends of the conveyor belt close to the discharge port of the feed hopper and the inlet of the collection box, respectively; the weighing roller is installed below and in contact with the conveyor belt; and the drive motor is connected to the conveyor belt for transmission. A display and control unit is electrically connected to the feed hopper and the conveying and weighing assembly, including a display screen, control buttons, and a controller.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] like Figures 1 to 2 As shown, this utility model provides a weighing tool for self-mixed mortar on construction sites, comprising:

[0020] Support frame 1, independently fixed;

[0021] The feed hopper 2 is installed above the support frame 1, and its bottom is equipped with a discharge valve 21 that can be controlled to open and close;

[0022] The collection box 3 is installed at the bottom of the support frame 1, and its top has an opening;

[0023] The conveying weighing assembly 4 includes a conveyor belt 41, a weighing idler roller 42, and a second drive motor 43. The two ends of the conveyor belt 41 are close to the discharge port of the feed hopper 2 and the feed port of the collection box 3, respectively. The weighing idler roller 42 is installed below the conveyor belt 41 and in contact with it. The drive motor 43 is connected to the conveyor belt 41 for transmission.

[0024] The display control unit 5 is electrically connected to the feed hopper 2 and the conveying weighing assembly 4, and includes a display screen 51, control buttons 52 and a controller;

[0025] The feeding hopper 2 is used to hold the engineering mortar mixing materials. The opening and closing of the discharge valve 21 is controlled by the display control unit 5, so that the materials fall onto the running conveyor belt 41. During the conveying process, the weighing roller 42 measures the weight of the materials on the conveyor belt in real time and transmits the weight data to the display control unit 5. The controller in the display control unit 5 receives the weight data transmitted by the weighing roller 42 and displays it on the display screen 51 in real time. At the same time, the conveyor belt 41 continues to run, and the weighed and metered materials are collected in the collection box 3, thereby realizing the single weighing of a large amount of mortar materials. Through the automated feeding, weighing and conveying process, the manual operation links are reduced, the labor intensity of workers is reduced, and the fast weighing and conveying process speeds up the pace of the entire mixing process, improves construction efficiency, and can meet the requirements of construction progress on the construction site for fast-paced and high-intensity operations.

[0026] The feed hopper 2 is equipped with stirring blades 22 inside, and a first drive motor 23 is installed on the outside of the feed hopper 2 to drive the stirring blades 22 to rotate. Through the mechanical stirring of the stirring blades 22, the segregation of the components in the mortar material under the action of gravity can be effectively avoided, preventing the denser particles from sinking and the lighter particles from floating, reducing the accumulation and agglomeration of materials in the feed hopper 2, avoiding wear and blockage of the discharge valve 21 and the wall of the feed hopper 2 caused by material accumulation, reducing the probability of equipment failure, and extending the overall service life of the equipment.

[0027] The preferred conveyor belt 41 has anti-slip protrusions and side guards 412 on its surface. The anti-slip protrusions are evenly distributed in strips, and the side guards 412 are set on both sides of the conveyor belt 41. When the mortar material is placed on the conveyor belt 41, the anti-slip protrusions increase the friction between the material and the conveyor belt 41. These protrusions are in contact with the material surface, making it difficult for the material to slide relative to the conveyor belt 41. This ensures that the material moves stably with the conveyor belt 41 and avoids problems such as poor conveying and blockage caused by material sliding, thus ensuring the accuracy and continuity of weighing. At the same time, during the conveying process, due to the accumulation of material and changes in the conveying direction, the material will move to both sides of the conveyor belt 41. The side guards 412 play a blocking role, restricting the material within the effective conveying area of ​​the conveyor belt 41, ensuring that the material can be completely conveyed from the feed hopper 2 to the collection box 3.

[0028] Inclined guide plates 44 are provided between the discharge port of the feed hopper 2 and one end of the conveyor belt 41, and between the other end of the conveyor belt 41 and the feed port of the collection box 3. The guide plates 44 provide a transition channel for the material. When the material is discharged, the material 44 slides down the inclined surface of the guide plate, and its direction of movement gradually changes, so that it falls smoothly onto the conveyor belt 41. This ensures that the material will not be too fast and impact the conveyor belt 41, nor will it be too slow and cause blockage. When the material is fed, the position and inclination angle of the guide plates 44 ensure that the material falls accurately into the collection box 3, avoiding spillage.

[0029] Preferably, a cleaning brush 45 is provided below the conveyor belt 41, and the cleaning brush 45 contacts the surface of the conveyor belt 41. As the conveyor belt 41 moves, the bristles of the cleaning brush 45 rub against the surface of the conveyor belt 41. Through this friction, residual mortar material on the conveyor belt 41 is scraped off, causing the material to detach from the surface of the conveyor belt 41, thereby ensuring the cleanliness of the surface of the conveyor belt 41. Residual material on the conveyor belt 41 can affect the weighing accuracy of the weighing roller 42. The cleaning brush 45 removes residual material in time to avoid interference with the weighing results due to material residue, ensuring the accuracy of each weighing data and helping to ensure the accuracy of the mortar mixing ratio.

[0030] The preferred display control unit 5 also includes a data storage module and a communication module. The data storage module 54 is used to store weighing data, and the communication module can wirelessly communicate with the central control system at the construction site. The weighing data stored in the data storage module provides detailed data records for the construction process. Through this data, construction personnel can trace the weighing status of each batch of mortar materials, analyze the material usage at different times and in different construction locations, which helps to optimize the construction process and material ratio, and improve construction quality and efficiency. The communication module allows operators to remotely monitor the working status and weighing data of the weighing tools in the central control room. Management personnel can adjust the construction plan and resource allocation in a timely manner based on real-time data, achieving efficient management of the construction site.

[0031] The preferred support frame 1 has an inspection door 6 on its side. The inspection door 6 is movably connected to the support frame 1 via a connector, and a locking element is provided between them. The connector includes, but is not limited to, hinges, etc. This connection method allows the inspection door 6 to rotate around the axis of the connector, thereby realizing the opening and closing action. When it is necessary to inspect and maintain the components inside the support frame 1, such as some parts of the conveying weighing component 4, related circuits, etc., the operator can open the passage to enter the interior by rotating the inspection door 6. The locking element includes, but is not limited to, door locks, bolts, etc. After the inspection door 6 is closed, the locking element is operated to firmly fix the inspection door 6 to the support frame 1, thereby locking and preventing the accidental opening of the inspection door 6. The design of the connector and the locking element facilitates maintenance while ensuring safety.

[0032] Preferably, it also includes an alarm component 7, which is connected to the controller of the display control unit 5. The controller receives information from various electrical components and immediately sends a command to the alarm component 7 when it receives an abnormal signal. The alarm component 7 includes an audible and visual alarm device, such as a buzzer emitting a sharp sound and a warning light flashing different colors, to attract the attention of operators, handle abnormal situations in a timely manner, and promptly remind them of abnormal situations that may affect construction safety, so as to ensure the safety of personnel and equipment at the construction site.

[0033] This utility model discloses a weighing tool for self-mixed mortar at construction sites. During operation, the required weight of the material is first set according to the mortar mix ratio using the control button 52 of the display control unit 5, and various alarm thresholds of the alarm component 7 are simultaneously set. Then, the mortar material to be weighed is loaded into the feed hopper 2, and the first drive motor 23 is started, driving the mixing blades 22 to rotate, initially mixing the material in the feed hopper 2 to ensure uniform mixing and prevent material segregation. The discharge valve 21 at the bottom of the feed hopper 2 is opened, and the material falls onto the conveyor belt 41 by gravity through the inclined guide plate 44. The conveyor belt 41 is driven by the second drive motor 43, and the weighing roller 42 measures the weight of the material on the conveyor belt 41 in real time and transmits the data to the display control unit 5. During the conveying process, anti-slip protrusions prevent the material from sliding and provide support. Side 412 prevents material spillage; the weighed material is conveyed to the collection box 3 via the guide plate 44; during the operation of the conveyor belt 41, the cleaning brush 45 continuously cleans the surface of the conveyor belt to prevent material residue; the operator observes the real-time weight data displayed on the display screen 51, and when the set value is reached, the display control unit 5 automatically controls the discharge valve 21 of the feed hopper 2 to close. At the same time, the controller stores the weighing data in the data storage module, and can transmit the data to the central control system at the construction site through the communication module; if an abnormality occurs during the operation, the alarm component 7 will immediately issue an audible and visual alarm to remind the operator to handle it in time. The operator will check the problem and make corresponding repairs or adjustments according to the alarm prompts; after the weighing of the mortar material is completed and the collection box 3 has collected the weighed material, the subsequent mortar mixing work can be carried out.
