Technical Field

[0001] The utility model relates to the technical field of recycled aggregate production, in particular to a screen clearing component for recycled aggregate production. Background Art

[0002] Recycled aggregate refers to secondary use materials obtained through specific processing during the recycling of construction waste. It mainly comes from discarded concrete, broken bricks and other construction waste. Recycled aggregate is divided into recycled coarse aggregate and recycled fine aggregate according to the nominal particle size. It is widely used in various engineering projects, including but not limited to industrial and civil construction projects, municipal engineering, road engineering and sponge city construction projects, which not only saves resources but also is beneficial to environmental protection.

[0003] In the process of producing recycled aggregate, the aggregate needs to be crushed and then screened through a sieve. Since the raw material is construction waste containing a large amount of impurities, some aggregates will be stuck in the sieve holes inside the sieve when the sieve is screening the aggregate, which will cause the sieve to be easily blocked. At the same time, the aggregates will also carry a large amount of soil, and the accumulation of soil will deepen the blockage of the screen. Manually cleaning out the aggregates and soil stuck in the sieve holes requires a lot of working time, which affects the working efficiency of the entire production line. Utility Model Content

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0022] The embodiment of the present application provides a screen blockage clearing component for recycled aggregate production, which can realize continuous impact of the screen by an impact ball through an impact component, thereby knocking out the aggregate stuck inside the screen, and allowing the aggregate to roll into the collection frame b through the opening, thereby achieving the effect of clearing the screen, and can flush the screen while impacting through a flushing component, thereby flushing the sludge inside the screen to improve the clearing effect, and at the same time can adjust the angle of the water spray gun so that the water spray gun can flush various parts of the screen to avoid omissions.

[0023] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1

[0025] like Figure 1-Figure 2 As shown, a screen clearing assembly for recycled aggregate production includes: a screening box 1, a feeding port 101 arranged at the top of the screening box 1, a screen 102 arranged inside the screening box 1, a collecting frame a103 is provided at the bottom of the screen 102, an opening 104 is opened on one side of the outer end of the screening box 1, a collecting frame b105 is placed on one side of the screening box 1, and the collecting frame b105 is located at the bottom of the opening 104, an impact assembly arranged at the bottom of the screen 102, used for impacting the screen 102, and a flushing assembly arranged inside the screening box 1, used for flushing the screen 102.

[0026] Among them, reference Figure 1-Figure 5 The impact assembly includes: a sleeve 2 arranged at the bottom of the screen 102, a rocker 201 arranged at one side of the outer end of the sleeve 2, an impact ball 202 is fixedly connected to the end of the rocker 201, and the impact ball 202 is made of rubber material, a transmission rod 203 sleeved inside the sleeve 2, the transmission rod 203 extends to the outside of the screening box 1 and is connected to a swing plate 204, and teeth 205 are arranged on the outside of the swing plate 204. A servo motor 3 is installed on one side of the top of the screening box 1, and a half gear 301 is driven and connected to one side of the servo motor 3, and the half gear 301 is located at the top of the swing plate 204.

[0027] When the screen 102 is to be cleared, the servo motor 3 is started through the control panel arranged outside the screening box 1, and the servo motor 3 drives the half gear 301 on the top of the swing plate 204 to rotate. When the half gear 301 rotates, its outer teeth begin to mesh with the teeth 205 on the outer side of the swing plate 204, thereby driving the swing plate 204 to rotate. Since the swing plate 204 is connected to the transmission rod 203, the transmission rod 203 extends to the inside of the screening box 1 and is sleeved inside the sleeve 2, thereby driving the swing rod 201 and the impact ball 202 to swing away from the screen 102, and then after the half gear 301 rotates half a circle, the swing plate 204 The outer teeth 205 will lose driving force and support. At this time, the impact ball 202 will fall freely under the influence of gravity and then hit the screen 102. Then, while the half gear 301 continues to rotate, it will drive the swing plate 204 to rotate again, and perform this reciprocating motion, thereby continuously hitting the screen 102, thereby knocking out the aggregate stuck inside the screen 102. The screen 102 is tilted inside the screening box 1, and the aggregate knocked out from the inside of the screen 102 will roll toward the opening 104 into the collecting frame b105, wherein a stepped surface is provided in the middle section of the screen 102 to facilitate the impact of the impact ball 202 on the screen 102.
