Description

Technical Field

[0001] The utility model relates to a vibrating screen machine, in particular to a shock-type standard vibrating screen machine, belonging to the technical field of vibrating screen machines. Background Art

[0002] Commercial concrete, also known as ready-mixed concrete, refers to pre-mixed concrete mixtures of qualified quality, which are sold to construction units in the form of commodities and transported to construction sites for pouring. Commercial concrete is the production process of concrete, from raw material selection, mix ratio design, selection of admixtures and admixtures, concrete mixing, concrete transportation to the construction site, etc., which is centralized from construction sites to mixing stations, which are managed and operated uniformly by the mixing stations and supply various finished products to construction units in the form of commodities.

[0003] The vibrating screen machine is a machine that is used in conjunction with a test sieve to perform material particle size analysis (screening analysis) instead of manual screening. In the process of concrete testing, it is often necessary to screen the raw materials, sand and gravel, so it will be used frequently. The principle of vibrating screen screening is as follows: the vibrating screen machine is provided with multiple screens, and the multiple screens are coaxially stacked in the vertical direction. The diameters of the multiple screens gradually decrease from top to bottom. After being neatly stacked, they are pressed tightly, and then the vibration is used to drive the multiple screens to vibrate synchronously. Particles with small particle sizes will fall until they enter the corresponding screens. The traditional vibrating screen machine includes a base, a vibration table, a screen seat arranged on the vibration table, a number of screens of different sizes arranged on the screen seat, a clamping member for clamping the screen, and a sleeve rod for installing the clamping member, and the clamping member is slidably sleeved with the sleeve rod.

[0004] The above-mentioned traditional technical solution has the following defects: after the clamping piece clamps several screens, it is necessary to screw the bolts (positioning screws) and press them against the sleeve rod of the frame to ensure that the clamping piece is relatively fixed. However, in general, there are three sleeve rods, so each time the filter screen is disassembled and installed, three bolts need to be loosened and tightened, and the positioning screws are generally rotated manually, which makes the disassembly and assembly cumbersome and affects the efficiency. In this regard, the improvement means of the prior art is to set a clamping rod in the clamping piece, and drive the clamping rod to slide by tightening the screw in the middle of the clamping piece and then press it against the sleeve rod to fix the clamping piece. However, this structure is too complicated. If the internal structure of the clamping piece is damaged, it is difficult to repair, which makes the production and maintenance costs high.

[0005] Secondly, during the use of the multi-layer screens of the vibrating screen machine of the prior art or after the material screening is completed, if the middle or lower screen is to be removed, it is necessary to open the clamping parts provided on the vibrating screen machine, and then remove the screens of the first few layers before taking out the middle or lower screen, and then put the previously removed screens back for use in screening materials. The process is relatively cumbersome and the work efficiency is low.

[0006] In addition, the screen frames of the vibrating screen machine are connected by direct overlap, and the screen frames are limited by the pressure between the clamp and the screen plate in the vertical direction and the friction caused by the pressure in the horizontal direction. During use, the vibrating screen machine is constantly subjected to high-intensity shock force, and the screen frames are prone to loosening, which makes the connection stability between the screen frames worse, easily causing noise and even causing material spillage, affecting the vibrating screen effect.

[0015] Furthermore, the lower side of the clamping member corresponding to the position of the first connecting block of the screen frame is also hinged with fasteners. After the clamping member clamps the multiple layers of screen frames on the screen seat, it is locked with the first connecting block on the topmost screen frame through the fasteners hinged on its lower side.

[0016] Furthermore, the screw lengths of the fasteners on the movable clamping plate, the fasteners on the screen frame and the fasteners on the pressing member are different.
