Abstract
Description
Technical Field
[0001] This utility model relates to the field of hopper technology, specifically to an aggregate hopper. Background Technology
[0002] In building construction, road construction, and many other fields involving concrete production, the handling and use of aggregates is a crucial step. Traditional aggregate handling processes often require screening aggregates of different particle sizes to meet the specific requirements of various construction techniques regarding aggregate fineness.
[0003] Currently, common aggregate screening equipment is typically complex in structure, bulky, and inconvenient to operate. In practical use, some screening devices struggle to flexibly adjust the particle size standards. When faced with varying engineering conditions or product formulations requiring different aggregate fineness, it often necessitates replacing the entire screening equipment or undertaking large-scale modifications and adjustments. This not only consumes significant manpower, resources, and time but also severely impacts the progress and efficiency of project construction.
[0004] In addition, traditional screening equipment is not precise enough in the separation and collection of aggregates during the screening process, which can easily lead to the mixing of coarse and fine aggregates or chaotic collection, resulting in unstable quality of concrete and other products in subsequent production processes, and affecting the strength and durability of engineering structures.
[0005] Based on the above-mentioned problems and shortcomings, there is an urgent need for a new type of aggregate hopper that can conveniently adjust the screening particle size and accurately divert and collect aggregates of different coarse and fine sizes, so as to adapt to the increasingly diverse and complex engineering construction and production needs, improve the efficiency and quality of aggregate processing, reduce production costs, and ensure the stability of project quality. Utility Model Content
[0006] In view of the shortcomings of the prior art, this utility model provides an aggregate hopper.
[0007] The technical solution adopted by this utility model is as follows: an aggregate hopper, including a hopper support and a hopper body fixed on the hopper support, a filter plate is inclinedly arranged inside the hopper body, the filter plate is provided with filter holes, the diameter of the filter holes gradually increases from high to low, a discharge port is provided at the bottom of the hopper body, the discharge port is divided into a fine material outlet and a coarse material outlet by a partition plate, sliding rods are provided on both sides below the filter plate, a sliding plate is slidably connected to the sliding rod, an elastic partition cloth is connected between the sliding plate and the partition plate, and a positioning mechanism is also provided on one side of the sliding plate for fixing the sliding plate at a certain position of the sliding rod.
[0008] Furthermore, a support step is provided on the hopper body at the bottom of the filter plate, and a buffer spring is provided between the support step and the filter plate.
[0009] Furthermore, a vibration device is also provided at the bottom of the filter plate.
[0010] Furthermore, the positioning mechanism includes a screw fixedly connected to the slider and a fixing nut threadedly connected to the screw, the screw extending from an elongated groove on the side wall of the hopper body.
[0011] Furthermore, a number of welding blocks are spaced apart on the outer wall of the hopper body, and the welding blocks are welded to the hopper support.
[0012] The beneficial effects of this utility model are:
[0013] 1. High-efficiency screening and precise flow separation: This aggregate hopper features a unique design with inclined filter plates inside the hopper body, where the filter hole diameter gradually increases from high to low. This design achieves natural grading and screening of aggregates during the descent. Coarse aggregates fall through the larger holes at the lower part of the filter plate due to gravity, while fine aggregates fall through the smaller holes at the higher part. A separator plate further divides the outlet into a fine aggregate outlet and a coarse aggregate outlet. An elastic separating cloth further ensures precise flow and collection of coarse and fine aggregates, effectively preventing mixing and greatly improving the accuracy and efficiency of aggregate screening. This provides stable quality aggregate raw materials for subsequent concrete and other product production, ensuring the reliability and durability of engineering structures.
[0014] 2. Flexible adjustment of screening particle size: The sliding rods and sliding plate connected to the slides on both sides below the filter plate, along with the positioning mechanism on one side of the slide plate, constitute a convenient particle size adjustment mechanism. Users can achieve different particle size screening by simply sliding and fixing the slide plate according to the aggregate coarseness requirements of different engineering conditions or product formulas.
[0015] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0021] This utility model provides an aggregate hopper.
[0022] In this embodiment, refer to Figure 1-2 The aggregate hopper includes a hopper support 1 and a hopper body 2 fixed on the hopper support 1. A filter plate 3 is inclinedly arranged inside the hopper body 2. The filter plate 3 is provided with filter holes 4. The diameter of the filter holes 4 gradually increases from high to low. A discharge port 5 is provided at the bottom of the hopper body. The discharge port 5 is divided into a fine material outlet 7 and a coarse material outlet 8 by a partition plate 6. Slide rods 9 are provided on both sides below the filter plate. A slide plate 10 is slidably connected to the slide rods 9. An elastic partition cloth 11 is connected between the slide plate 10 and the partition plate. A positioning mechanism 12 is also provided on one side of the slide plate for fixing the slide plate at a certain position of the slide rod.
[0023] In the above technical solution, by setting an inclined filter plate inside the hopper body and gradually increasing the diameter of the filter holes from high to low, the aggregate is naturally screened according to its particle size. The bottom discharge port is designed with separate outlets for fine and coarse materials. Combined with the separation effect of the elastic separating cloth, this ensures that aggregates of different particle sizes can be effectively separated and discharged separately, improving screening efficiency and accuracy. The combination of the sliding rod and slide plate with the application of the elastic separating cloth not only ensures effective separation of coarse and fine materials but also allows users to flexibly control the screening standards by adjusting the position of the slide plate to adapt to different working conditions. For example, sliding the elastic separating cloth towards the higher end of the filter plate can increase the lower limit of the screening particle size for coarse materials and the upper limit of the screening particle size for fine materials. More specifically: For example, if the pore sizes of the filter plate, from highest to lowest, are 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm, and the separating cloth is between 2.5-3mm, then the diameter range of the fine material is 1.5-2.5mm, and the diameter range of the coarse material is 3-4mm. If the separating cloth slides upwards to between 1.5-2mm, then the diameter range of the fine material is 1.5-1.5mm, and the diameter range of the coarse material is 2-4mm.
[0024] Specifically, a support step 13 is provided on the hopper body at the bottom of the filter plate, and a buffer spring 14 is provided between the support step 13 and the filter plate.
[0025] In this embodiment, a support step is provided at the bottom of the filter plate, and a buffer spring is installed between it and the support step. This can absorb the impact force generated on the filter plate when the aggregate falls to a certain extent, reducing equipment wear and extending service life. In addition, the buffer spring can also play an auxiliary role in resetting, which helps maintain the working stability of the filter plate.
[0026] Specifically, a vibration device is also provided at the bottom of the filter plate.
[0027] In this embodiment, the addition of a vibration device (not shown in the figure) can effectively prevent aggregate from accumulating or clogging on the filter plate, thereby improving screening efficiency. Simultaneously, vibration helps promote smooth flow of aggregate along the filter plate surface, further enhancing the screening effect, especially for wet or highly viscous aggregate materials, where its advantages are more pronounced.
[0028] Specifically, the positioning mechanism includes a screw 15 fixedly connected to the slider and a fixing nut 16 threadedly connected to the screw 15. The screw extends from an elongated groove 17 on the side wall of the hopper body.
[0029] In this embodiment, the positioning mechanism consists of a screw and a fixing nut. This design allows the operator to precisely fix the slide plate in the desired position, thereby achieving fine adjustment of the screening particle size.
[0030] Specifically, a number of welding blocks 18 are spaced apart on the outer wall of the hopper body, and the welding blocks are welded to the hopper support.
[0031] In this embodiment, welded blocks are spaced apart on the outer wall of the hopper body and welded to the hopper support, significantly enhancing the stability and load-bearing capacity of the entire structure. This design not only improves the safety performance of the equipment but also enables the hopper to withstand greater loads, making it suitable for a wider range of applications.
[0032] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
