Problems solved by technology

[0003] In the construction of municipal buildings, in order to meet the construction requirements, it is necessary to screen the sand of building materials to obtain relatively fine sand. However, during the use of the current sand screening device, the sand is easy to cause excessive accumulation, or even block, resulting in Sand screening operation is relatively difficult, which directly restricts the quality of sand screening. Therefore, a quick sand screening device for municipal engineering construction is now provided to solve the above technical problems

Embodiment 1

[0021] see Figure 1-3 , a rapid sand screening device for municipal engineering construction, comprising a fixed frame 1, a cylinder 22 is hinged on the fixed frame 1, a first sieve plate 25 is embedded in the bottom of the cylinder 22, and a sand inlet is installed on the top of the first sieve plate 25 The bucket 20 can inject sand to be screened into the cylinder 22 through the sand inlet bucket 20, and the first sieve plate 25 provided in the cylinder 22 performs the primary screening function on the sand. The cylinder 22 is rotatably provided with a connecting frame 23 driven by a drive motor II24, and the connecting frame 23 is pivotally connected with two parallel screw shafts 21, and the rotation of the connecting frame 23 can drive the screw shaft 21 to rotate, realizing the alignment of the cylinder. 22 The flipping effect of the internal sand improves the looseness and fluidity of the sand and improves the screening effect.

Embodiment 2

[0027] On the basis of Embodiment 1, in addition, the guide rod 10 is installed horizontally on the fixed frame 1, the sliding sleeve on the guide rod 10 is provided with a sliding sleeve 11 fixedly connected with the folding rod 12, and the upper rack 9 is fixed to the sliding sleeve 11. connect. The rotation of the incomplete gear 8 meshes intermittently with the upper rack 9. When the upper rack 9 moves to the left under the engagement of the incomplete gear 8, the angle between the support rod I13 and the support rod II14 increases, and the cylinder 22 is obtained. Lifting, when the upper rack 9 is separated from the incomplete gear 8, under the gravity of the cylinder 22, the angle between the support rod I13 and the support rod II14 decreases, and the cylinder 22 moves downward, so that the cylinder 22 is repeatedly realized. The up and down vibration promotes the screening of sand.

Abstract

The invention discloses a rapid sand screening device for municipal engineering construction, and relates to the technical field of municipal engineering. The device comprises a fixing frame, whereina cylinder is hinged to the fixing frame, a first screen plate is embedded at the bottom of the cylinder, a sand inlet hopper is arranged at the top of the first screen plate, a lower support and an upper support are fixedly arranged on the cylinder and the fixing frame respectively, a bent rod in drive connection with a reciprocating mechanism is hinged to the right ends of a supporting rod I andthe supporting rod II, and a second screen plate is in transmission connection with the reciprocating mechanism. According to the device, sand inside the cylinder can be sufficiently rotated and scattered by the rotation of a spiral shaft, so that the sand is prevented from caking in the sand screening process, the loose degree of the sand is improved, the fluidity is improved, and subsequent sand screening is ensured to be efficient; and vibrating type swinging of the cylinder can be realized through driving of the arranged reciprocating mechanism, so that the screening efficiency of the first screen plate on the sand is promoted, and meanwhile, the second screen plate can vibrate up and down while moves back and forth, so that sand screening is further ensured to be efficient.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a quick sand screening device for municipal engineering construction. Background technique [0002] In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity, telecommunications, Heat, gas, etc., as well as the construction of squares and urban greening, all belong to the category of municipal engineering. [0003] In the construction of municipal buildin...
