Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a vibrating screen for building construction with stable operation. Background Art

[0002] The vibrating screen works by utilizing the vibration generated by the excitation motor. By changing the curve shape of the motion trajectory of the screen surface and the motion trajectory of the material on the screen surface, the material screening is achieved. Under the combined effect of the exciting force and the material's own gravity, the material is thrown up on the screen surface and jumps forward to move in a straight line, thereby achieving the purpose of screening and grading the material.

[0003] As disclosed in the authorization announcement number CN206701671U, a stable vibrating screen for construction is disclosed, including a shock-absorbing stabilizing device and a machine body. The shock-absorbing stabilizing device includes a shock absorber, a buffer rubber layer, a hydraulic sleeve, and a spring. A spring is fixed on the top of the buffer rubber layer, and a hydraulic sleeve is arranged on the left side of the spring. The buffer rubber layer is fixedly connected to the shock absorber on the top right side, and the buffer rubber layer is fixedly connected to the equipment base below. A support leg is welded below the equipment base, and a storage box is arranged on the right side of the support leg. The shock absorber is fixedly connected to the machine body above, and the machine body includes a feed port, a screen bucket, a discharge port, a motor, a screening net, and an electric control box. An electric control box is arranged in front of the outer side of the screen bucket, and a motor is arranged on the right side of the electric control box. The stable vibrating screen for construction has the advantages of high production efficiency, no dust pollution, and easy use, and can be widely promoted and used.

[0004] However, the existing vibrating screens are damaged due to long-term friction and impact when materials enter, so the screen needs to be replaced frequently, which increases the cost of use and affects the efficiency. At the same time, the high vibration frequency and large vibration amplitude during vibration will cause the supporting structure to be affected and vibrate, resulting in poor overall support stability. Utility Model Content

[0005] The utility model aims to provide a vibrating screen for building construction with stable operation, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This is a stable vibrating screen for construction. Materials can be connected through the feed bin. When the materials fall, the anti-wear pads in the feed bin can provide buffering to avoid damage to the feed bin due to friction and impact when the materials fall.

[0023] A vibrating screen for construction with stable operation comprises a shock absorbing mechanism 101, a vibrating mechanism 102 and a supporting mechanism 103, wherein the vibrating mechanism 102 is located at the top of the shock absorbing mechanism 101, and the supporting mechanism 103 is located at the bottom of the shock absorbing mechanism 101; the shock absorbing mechanism 101 comprises a supporting plate 104, a vibration spring 105 is fixedly installed in the middle of the top of the supporting plate 104, a pad 106 is fixedly installed around the top of the supporting plate 104, shock absorbing springs 201 are fixedly installed between the pads 106, a telescopic cylinder 202 is movably installed in the shock absorbing spring 201, and a telescopic rod 203 is movably installed at the top of the telescopic cylinder 202.

[0024] Through the above scheme, vibration support is performed through the support plate, and the vibration spring can make the vibration bin rebound when its top vibrates, so that the vibration is stable and high-frequency, and soft support is produced by the shock-absorbing spring, which reduces the vibration force transmitted to the support frame. At the same time, due to the vibration, the telescopic rod is extended and retracted in the telescopic cylinder to generate a damping force, and the damping force offsets the vibration force, so that when the vibration bin vibrates, the bottom support will not be affected by the vibration.

[0025] In this embodiment, preferably, the vibration mechanism 102 includes a feed bin 204 , in which an anti-wear gasket 205 is fixedly installed, and a vibration bin 206 is fixedly installed at the front end of the feed bin 204 , and the vibration bin 206 is fixedly installed on the top of the vibration spring 105 .

[0026] Through the above scheme, materials can be connected through the feed bin, and when the materials fall, the anti-wear pads in the feed bin can provide buffering to prevent the feed bin from being damaged due to friction and impact when the materials fall.

[0027] In this embodiment, preferably, a front inclined plate 301 is fixedly installed on the upper side of the vibration bin 206 , a screen 302 is movably installed in the front inclined plate 301 , and a rear inclined plate 303 is fixedly installed on the lower side of the vibration bin 206 .

[0028] Through the above scheme, the material can slide forward when it is driven to vibrate through the front inclined plate, the material can be screened when it vibrates and slides through the screen, and the screened material can slide backward through the rear inclined plate, so that the material can be transported separately after being screened.

[0029] In this embodiment, preferably, connecting plates 304 are movably installed at both ends of the vibration bin 206, connecting screws 305 are movably installed on the connecting plates 304, a cushion block 306 is fixedly installed at the front end of the connecting plate 304, and a vibrator 401 is fixedly installed at the front end of the cushion block 306.

[0030] Through the above solution, the connecting plate can be fixed by connecting screws, so that the vibrator can be installed at both ends of the vibration bin, and the vibrator and the connecting plate can be connected and supported by the pads.

[0031] In this embodiment, preferably, the support mechanism 103 includes a support frame 402 , a pad 106 is fixedly mounted on the bottom end of the support frame 402 , and a support leg 403 is fixedly mounted on the bottom end of the support frame 402 .

[0032] Through the above scheme, the shock-absorbing spring, telescopic rod and telescopic cylinder can be installed and supported by the support frame, the shock-absorbing spring, telescopic rod and telescopic cylinder can reduce wear during shock absorption through the pad, and the support frame can be supported by the support legs.

[0033] In this embodiment, preferably, a support frame 404 is fixedly installed on the lower side of the support leg 403 , and a support base plate 405 is fixedly installed on the bottom end of the support leg 403 .

[0034] Through the above solution, the overall support is made more stable through the support frame and the support base plate.

[0035] When using a stable vibrating screen for construction of this embodiment, the user places the conveying crawler on the top of the feed bin 204, and then conveys the material to the feed bin 204 through the conveying crawler. When the material falls, the anti-wear pad 106 in the feed bin 204 can provide a buffer to prevent the friction and impact of the material when it falls from causing damage to the feed bin 204. At this time, the vibrator 401 drives the vibration bin 206 to vibrate at the top of the vibration spring 105, so that the material is vibrated and screened on the screen 302. After screening, small particles are separated. The material falls onto the rear inclined plate 303 and slides out from the rear end of the vibration bin 206 through vibration. The large particles are screened out and slide out from the front end of the vibration bin 206 through vibration, so that the material screening is completed. During the vibration screening, the shock-absorbing spring 201 produces soft support, which reduces the vibration force transmitted to the support frame 402. At the same time, due to the vibration, the telescopic rod 203 is extended and retracted in the telescopic cylinder 202 to generate a damping force, which offsets the vibration force. Therefore, when the vibration bin 206 vibrates, the bottom support will not be affected by the vibration, thereby increasing the support stability.
