Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a detachable multi-functional concrete aggregate screening and washing shovel. Background Art

[0002] Concrete is an indispensable material in the fields of construction and engineering. Its aggregates include substances such as stones, sand, cement, and fly ash. To improve the performance of concrete, many related studies have been carried out in the scientific research field. Usually, when conducting research on the performance of concrete, it is necessary to form concrete specimens, and this process involves the preparation, mixing, vibration compaction, and plastering of concrete aggregates. Among them, when preparing concrete aggregates, in order to avoid other substances on the surface of the aggregates (especially stones) affecting the performance of concrete, washing is often carried out. Generally, it is washed and stirred after being laid flat, but there will still be a small amount of residual impurities remaining at the bottom of the aggregates; and during the vibration compaction process, the feeding of aggregates is involved. It is often necessary to add fine aggregates in the later stage of vibration to facilitate leveling and compaction. At present, it is mainly manually selected and removed, but the vibration time and the feeding ratio are the key factors affecting the quality of the specimens, and manual removal is time-consuming. Therefore, aiming at the deficiencies in the process of preparing concrete specimens, a detachable multi-functional concrete aggregate screening and washing shovel is designed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a detachable multi-functional concrete aggregate screening and washing shovel, which can be applied to the cleaning and screening of concrete aggregates. In order to achieve the above technical features, the purpose of the utility model is realized as follows:

[0004] A detachable multi-functional concrete aggregate screening and washing shovel includes a shovel handle and a shovel head. A plurality of through holes for screening aggregates are provided on the shovel head, and the shovel head is connected to the shovel handle in a detachable manner.

[0005] On the left and right sides of the front surface of the shovel head, symmetrically arranged upwardly protruding blocking parts are provided.

[0006] A plurality of horizontally distributed rib plates are provided between the two blocking parts.

[0007] The shovel head is connected to the shovel handle through a rectangular key. The connecting part provided at the first end of the rectangular key is connected to a hoop clamped outside the shovel handle through a fastener, and a limiting hole for cooperating with the second end of the rectangular key is provided on the hoop.

[0008] The number of the shovel heads is multiple, and the aperture diameters of the through holes on each shovel head are not equal.

[0009] The utility model has the following beneficial effects:

[0010] 1. By providing multiple through holes on the shovel head, on the one hand, after shoveling the aggregate to be washed onto the iron shovel, it can be cleaned by flushing or soaking in water, and impurities will be filtered through the through holes, thus obtaining the required impurity-free aggregate. On the other hand, after shoveling the screened aggregate onto the iron shovel, it can be screened by turning and shaking to screen out the required coarse aggregate and fine aggregate, so it can be applied to the cleaning of concrete aggregates and the screening of aggregates;

[0011] 2. There are multiple rib plates distributed horizontally between the two blocking parts. Through the setting of the rib plates, on the one hand, the structural strength of the shovel head is enhanced. On the other hand, when cleaning the aggregate or washing and screening the material, the material on the shovel head is not easy to slide off, indirectly improving the operation efficiency.

[0012] 3. The number of shovel heads is multiple, and the through hole diameters of each shovel head are not equal. By replacing different shovel heads, it is suitable for the cleaning and screening of aggregates of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following further describes the embodiments of the present invention in conjunction with the drawings.

[0019] Referring to the attached Figures 1-3 , in order to achieve the above technical features, the object of the present invention is achieved as follows:

[0020] A detachable multi-functional concrete aggregate screening and washing shovel, comprising a shovel handle 1 and a shovel head 2. A plurality of through holes 2a for screening the aggregate are provided on the shovel head 2. The shovel head 2 is detachably connected to the shovel handle 1. By providing a plurality of through holes 2a on the shovel head 2, on the one hand, after shoveling the aggregate to be washed onto the iron shovel, it can be washed by flushing or soaking in water, and impurities will pass through the through holes for filtration, so as to obtain the required impurity-free aggregate. On the other hand, after shoveling the screened and washed aggregate onto the iron shovel, it can be screened by turning and shaking to screen out the required coarse aggregate and fine aggregate, so that it can be applied to the cleaning of concrete aggregate and the screening of aggregate.
