Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete recycling, and in particular relates to a sand and gravel separation device used for concrete recycling. Background Art
[0002] The sand and gravel separator is mainly composed of a guide chute and a main machine, which can be flexibly arranged when the site area is limited. The guide chute collects the materials dumped from the concrete mixer truck and then enters the drum screen to screen the gravel. The sewage and sand will fall into the spiral water bucket below the drum screen. The sand settles at the bottom of the water bucket and is lifted out by the spiral sand lifting rod. The sewage flows through the overflow port at the top of the spiral water bucket and enters the mixing tank for collection. The mixing tank is equipped with a stirrer to prevent the slurry water from settling and hardening. The sewage in the mixing tank can be pumped into the mixing plant to produce concrete by a sewage pump or filtered into clean water by a filter press and then recycled into a clean water tank.
[0003] The existing sand and gravel separation device mainly relies on the gravity of the sand and gravel and the inclination of the discharge port to achieve discharging. When the amount of sand and gravel discharged is small, the gravity of the sand and gravel itself and the inclination of the discharge port are not enough to discharge the sand and gravel, which can easily cause poor discharge and affect the overall small material speed. Therefore, there are great limitations in use and there is room for improvement. Utility Model Content
[0004] The utility model aims to provide a sand and gravel separation device for concrete recycling, so as to solve the problem of poor material discharge in the existing sand and gravel separation device proposed in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand and gravel separation device for concrete recycling, comprising a guide box, the bottom end surface of which is inclined, and a discharge port is provided at the lowest point of the inclination; a screening machine, having a feed port and a discharge port, wherein the feed port is connected to the discharge port of the guide box, and is used to inject concrete into the screening machine for subsequent sand and gravel separation; a discharge assembly is provided in the discharge port, and the discharge assembly is composed of a fixed discharge piece and a dynamic discharge piece, wherein the fixed discharge piece is fixed as a whole inside the guide box, and one end of the dynamic discharge piece is located in the guide box and at the bottom of the fixed discharge piece, and the other end of the dynamic discharge piece passes through the outside of the guide box, and the fixed discharge piece is elastically connected to the dynamic discharge piece. During material discharge, sand and gravel will be transmitted from the fixed discharge piece to the dynamic discharge piece, and the dynamic discharge piece will vibrate at this time to achieve rapid discharge of sand and gravel.
[0006] Preferably, the fixed discharge member is a discharge plate, and the discharge plate is fixed to the inner wall of the material guide box by bolts.
[0007] Preferably, the dynamic discharge member includes a discharge plate, one end of which is located outside the bottom end of the discharge plate, and fixed columns are fixed on the inner sides of the discharge plate and the discharge plate, and tension springs are installed on the two fixed columns. During material unloading, when sand and gravel pass through the discharge plate, gravity is provided to the discharge plate. At this time, the discharge plate descends and stretches the tension spring, and the tension spring rebounds, thereby achieving up and down vibration of the discharge plate and realizing rapid material unloading. A mounting seat is fixed to the bottom end of the discharge plate, and a shaft connected to the material guide box is movable through the mounting seat, thereby realizing installation and ensuring that the discharge plate rotates around the axis of the shaft to achieve the purpose of up and down vibration.
[0008] Preferably, a support plate is fixed inside the material guide box, and a spring is fixed on the support plate. The spring is connected to the bottom of one end of the discharge plate. When the discharge plate vibrates up and down, the spring will be squeezed, and the vibration efficiency can be improved through the rebound of the spring.
[0009] Preferably, the inclination angle of the discharge plate is equal to or greater than the inclination angle of the discharge plate, thereby facilitating better discharge.
[0010] Preferably, the top of the rear surface of the material guide box is vertically raised upward to form a splash-proof area, and a sound-absorbing panel is provided on the inner wall of the vertical raised area to reduce noise during production.
[0011] Preferably, a hook is installed on the rear side of the top end of the sound absorbing panel, and the hook is hung on the vertical raised area of the material guide box.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The designed discharge assembly can receive the rolling force of the falling sand and gravel and convert it into up and down vibration force to increase the discharge speed. It can also be stored when not in use. The overall flexibility is high. The discharge assembly has a simple structure and is easy to process and produce, which improves the shortcomings of the existing structure in use. BRIEF DESCRIPTION OF THE DRAWINGS
