Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, and in particular to a quantitative shovel for construction engineering. Background Technology

[0002] In construction scenarios such as indoor plastering, applying mud and sand mixtures, casting small precast components, and local repairs, short-handled hand shovels are commonly used due to their ease of operation. They can be scooped and placed with one hand and are suitable for handling loose materials such as cement and mortar. With their flexible short-handled design, they can work quickly in narrow spaces or delicate construction processes, effectively improving the efficiency of basic construction and making them one of the indispensable basic tools on the construction site.

[0003] However, in construction engineering, interior plastering requires strict proportions of sand and cement, and the casting of small precast components has fixed standards for the amount of materials to be filled. Different construction stages all have strict requirements for the accuracy of material usage. However, current construction projects use hand shovels, relying solely on manual experience to control the loading amount. Due to differences in the construction workers' feel and judgment, the actual loading amount deviates greatly from the theoretical value. This not only causes material waste, such as excessive cement increasing costs and mortar imbalance requiring rework, but also directly affects the construction quality. Plaster layers with uneven material usage will have thickness differences, making them prone to cracking and falling off later. Precast components with deviations in filling amount may have insufficient structural strength and dimensional deformation, seriously restricting construction quality and project stability.

[0004] Therefore, a quantitative shovel tool for construction engineering is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a quantitative shovel for construction engineering, which can solve the problem that existing hand-held shovels used in construction engineering rely solely on manual experience to control the loading amount. Due to differences in the construction workers' feel and judgment, the actual loading amount deviates greatly from the theoretical value. This not only causes material waste, such as excessive cement increasing costs and mortar imbalance requiring rework, but also directly affects the construction quality. Uneven material usage in the plaster layer can lead to thickness differences, making it prone to cracking and peeling later. Deviations in the filling amount of precast components may result in insufficient structural strength and dimensional deformation, seriously restricting the construction quality and project stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metering shovel for construction engineering, comprising a bucket, an L-shaped handle welded to the front side of the bucket, a drain hole opened on the rear side of the bottom inside the bucket, a metering component installed inside the bucket, and a leveling structure installed on the top of the bucket. The metering component includes scale values ​​on both sides of the bucket. Slide grooves are provided on both sides of the bucket, and sliders are slidably connected inside the slide grooves. Adjustment plates are adhered to the outer sides of the sliders. A metering plate is provided on the front side of the bucket's interior, and the outer side of the metering plate is welded to the inner side of the slider. A threaded sleeve is welded to the right side of the front of the bucket, and an adjusting screw is threaded inside the sleeve. The rear side of the adjusting screw penetrates the front of the bucket, and its end is rotatably connected to the front of the metering plate. A turntable is welded to the front of the adjusting screw, and an auxiliary rod is welded to the front of the metering plate, with the front of the auxiliary rod penetrating the interior of the bucket.

[0007] Preferably, the leveling structure includes fixing blocks welded to both sides of the top of the bucket, and support blocks are welded to both sides of the front side of the bucket.

[0008] Preferably, a round rod is bolted to the inner side of the fixing block and the support block, and a spring is sleeved on the outer side of the round rod, with the rear side of the spring contacting the front side of the fixing block.

[0009] Preferably, a scraper is provided on the front side of the top of the bucket, both sides of the scraper are slidably connected to the outside of the round rod, the outer edge of the rear side of the scraper is fixedly connected to the front end of the spring, and a push handle is welded to the top of the scraper.

[0010] Preferably, the scale value is marked with a volume scale in mL and a mass scale in g on both sides. The mass scale is converted from the standard bulk density of commonly used building materials and corresponds to the volume scale. The corresponding quantitative value can be read directly according to the material type.

[0011] Preferably, an anti-stick pad is adhered to the bottom side inside the bucket, and the rear side of the top of the anti-stick pad has a groove that matches the drain hole.

[0012] Preferably, the surface of the L-shaped grip is covered with a rubber grip sleeve, and the outer side of the rubber grip sleeve has anti-slip texture.

[0013] Preferably, a top cover plate is bolted to the front side of the metering plate, and the top cover plate is located on the front side of the top of the bucket.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting up a bucket, an L-shaped handle, a drain hole, and a metering component, uses an adjusting screw to move the metering plate. Combined with the scale values ​​on both sides of the bucket, the amount of material scooped can be precisely controlled. This solves the problem of large loading deviation caused by the reliance on manual experience in existing short-handled hand shovels, avoids waste and rework caused by inaccurate material usage, and ensures the accuracy of indoor plastering mix ratio and the standard of filling volume for precast component casting, thereby improving construction quality and stability. The drain hole can promptly discharge materials outside the measurement range, thus adapting to the quantitative requirements of materials such as mud, sand, and cement. The L-shaped handle facilitates one-handed operation and meets the requirements of convenient operation. 2. This application, by setting a leveling structure, can quickly level the excess material on the top of the bucket that is not within the measurement range after scooping up the material, ensuring that the amount scooped up each time is consistent with the set value of the quantitative component, further improving the quantitative accuracy, avoiding measurement deviation caused by uneven material accumulation, and forming a double guarantee in conjunction with the quantitative component, efficiently meeting the stringent requirements for material usage in precision construction scenarios.

[0017] 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.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A metering shovel for construction engineering includes a bucket 1, an L-shaped handle 2 welded to the front side of the bucket 1, a drain hole 3 opened on the rear side of the bottom inside the bucket 1, a metering component 4 installed inside the bucket 1, and a leveling structure 5 installed on the top of the bucket 1. The metering component 4 includes scale values ​​41 on both sides of the bucket 1. Both sides of the bucket 1 are provided with grooves 42. A slider 43 is slidably connected inside the grooves 42. An adjusting plate 44 is bonded to the outside of the slider 43. A metering plate 45 is provided on the front side inside the bucket 1. The outside of the metering plate 45 is welded to the inside of the slider 43. A screw sleeve 46 is welded to the right side of the front side of the bucket 1. An adjusting screw 47 is threaded inside the screw sleeve 46. The rear side of the adjusting screw 47 passes through the front side of the bucket 1, and its end is rotatably connected to the front side of the metering plate 45. A turntable 48 is welded to the front side of the adjusting screw 47. An auxiliary rod 49 is welded to the front side of the metering plate 45. The front side of the auxiliary rod 49 passes through the interior of the bucket 1.

[0019] In this embodiment: by setting up a bucket 1, an L-shaped handle 2, a drain hole 3, a metering component 4, and a leveling structure 5, during use, the operator holds the L-shaped handle 2 with one hand and first rotates the turntable 48 according to the amount of material required for construction, causing the adjusting screw 47 to rotate within the screw sleeve 46. This causes the adjusting screw 47 to push the metering plate 45 to move back and forth along the inside of the bucket 1. At the same time, the metering plate 45 causes the sliders 43 on both sides to slide within the groove 42. The adjusting plate 44 on the outside of the slider 43 moves with the slider 43 and corresponds to the scale values ​​41 on both sides of the bucket 1, thereby accurately setting the required quantity of material. The auxiliary rod 49 moves synchronously with the metering plate 45, enhancing the stability of the metering plate 45 during movement. When scooping materials, after the materials enter the bucket 1, materials outside the measurement range are discharged through the leakage hole 3 to avoid interfering with the metering accuracy. After scooping, the leveling structure 5 is used to level the unevenly accumulated materials at the top of the bucket 1, so that the amount of material is consistent with the metering value set by the metering plate 45. The whole operation process is convenient and simple. Through the combination of mechanical structure control and scale marking, it replaces manual experience judgment, ensuring that the amount scooped each time is accurate and stable, meeting the stringent requirements of material usage in different construction stages.

[0020] Specifically, such as Figure 4 As shown, the leveling structure 5 includes fixing blocks 51 welded to both sides of the top of the bucket 1, and support blocks 52 welded to both sides of the front side of the bucket 1.

[0021] Specifically, such as Figure 4 As shown, a round rod 53 is bolted to the inner side of the fixing block 51 and the support block 52, and a spring 54 is sleeved on the outer side of the round rod 53. The rear side of the spring 54 contacts the front side of the fixing block 51.

[0022] Specifically, such as Figure 4As shown, a scraper 55 is provided on the front side of the top of the bucket 1. Both sides of the scraper 55 are slidably connected to the outside of the round rod 53. The outer edge of the rear side of the scraper 55 is fixedly connected to the front end of the spring 54. A push handle 56 is welded to the top of the scraper 55.

[0023] In this embodiment: by setting the leveling structure 5, after scooping up the material, the push handle 56 is pushed forward to drive the scraper 55 to slide along the round rod 53. The scraper 55 can scrape off and level the excess material accumulated on the top of the bucket 1. After releasing the push handle 56, the spring 54 pushes the scraper 55 back to the initial position due to elastic reset, which is convenient for the next operation. The round rod 53 provides a stable sliding track for the scraper 55. The fixed block 51 and the support block 52 form a support to ensure that the leveling action is accurate and efficient. In conjunction with the metering component 4, it further ensures that the amount of material is consistent with the set value.

[0024] Specifically, such as Figure 3 , Figure 4 As shown, the scale value 41 is marked with volume scale in mL and mass scale in g on both sides. The mass scale is converted from the standard bulk density of commonly used building materials and corresponds to the volume scale. The corresponding quantitative value can be read directly according to the material type.

[0025] Specifically, such as Figure 4 As shown, an anti-stick pad 6 is bonded to the bottom side inside the bucket 1, and a groove matching the drain hole 3 is opened on the rear side of the top of the anti-stick pad 6.

[0026] In this embodiment: the mL and g scales of the scale 41 allow for direct reading based on the material type: for materials such as cement that are mixed by mass, the g scale is read; for materials such as mortar that are applied by volume, the mL scale is read. This eliminates the need for manual conversion, improving quantitative efficiency. The anti-stick pad 6 reduces material adhesion to the bottom of the bucket 1, and its groove matches the drain hole 3 to ensure that excess material is discharged smoothly, avoiding residue that could affect measurement accuracy.

[0027] Specifically, such as Figure 5 As shown, the surface of the L-shaped grip 2 is covered with a rubber grip sleeve 7, and the outer side of the rubber grip sleeve 7 has anti-slip texture.

[0028] Specifically, such as Figure 1 As shown, a top cover plate 8 is bolted to the front side of the metering plate 45, and the top cover plate 8 is located on the front side of the top of the bucket 1.

[0029] In this embodiment: by setting rubber grip 7 and top cover plate 8, the anti-slip texture of rubber grip 7 enhances the friction of hand grip, avoids slipping during operation, and improves the stability and comfort of single-handed operation. Top cover plate 8 can prevent splashed material from falling into the space on the front side of the top of bucket 1, thereby affecting the quantitative adjustment of the metering plate 45 inside bucket 1.

[0030] Working Principle: In the use of a metering shovel for construction projects, the operator first holds the L-shaped handle 2 with a rubber grip sleeve 7 in one hand. The anti-slip texture enhances grip stability and facilitates flexible operation. Then, depending on the type of material required for construction (such as cement or mortar), the operator observes the scale values ​​41 on both sides of the bucket 1. If the material is to be mixed by mass, refer to the g scale; if the material is to be mixed by volume, check the mL scale. By rotating the turntable 48, the adjusting screw 47 rotates within the screw sleeve 46, thereby pushing the metering plate 45 to move back and forth along the inside of the bucket 1. At the same time, the metering plate 45 drives the sliders 43 on both sides to slide within the grooves 42. The adjusting plate 44 on the outside of the slider 43 moves with it and corresponds to the scale value 41, thus accurately setting the required metering value. The auxiliary rod 49 moves synchronously with the metering plate 45. The movement of the metering plate 45 is ensured to be smooth. The top cover plate 8 can prevent material from splashing or falling dust, thus avoiding affecting the adjustment of the metering plate 45. When scooping material, the material enters the bucket 1. The anti-stick pad 6 on the bottom side of the bucket 1 can reduce material adhesion. Material outside the measurement range is discharged through the drain hole 3. The groove on the anti-stick pad 6 matches the drain hole 3 to ensure smooth discharge. After scooping, push the handle 56 forward to drive the scraper 55 to slide along the round rod 53. The scraper 55 scrapes the excess material accumulated on the top of the bucket 1. After releasing the handle 56, the spring 54 elastically resets and pushes the scraper 55 back to the initial position, so that the material quantity is consistent with the set value of the metering plate 45. The whole process uses mechanical structure and scale cooperation to replace manual experience judgment, achieve precise metering, and meet the strict requirements of material usage in different construction stages.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
