[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0029] like Figures 1-2 As shown, a vibrating feeder screen with dewatering and screening function in one embodiment of the present invention includes a screen box 1. A drainage structure is installed at the bottom of the screen box 1. The drainage structure can be a drain pipe 2. A vibration mechanism is installed on the screen box 1. A water filtration structure 3 is installed inside the screen box 1. The water filtration structure 3 includes a material collection area and a dewatering area. The material collection area is located above the dewatering area. Multiple drain outlets 301 are opened on the dewatering area. There is a drainage channel between the water filtration structure 3 and the screen box 1.
[0030] like Figures 1-2As shown, after the aggregate in the sand and gravel bin falls into the collection area on the filter structure 3, the vibration mechanism drives the screen box 1 to vibrate, causing the aggregate to gradually move downward along the filter structure 3 to the dewatering area. During the vibration process, the water mixed in the aggregate gradually enters the drain outlet 301 and falls into the drainage channel below, and then flows through the drainage channel and is discharged from the drain pipe 2.
[0031] The vibration mechanism can be selected from exciters or adjusted according to actual needs.
[0032] like Figures 1-2 As shown, the filter structure is equipped with baffles. The baffles can block water that is not discharged from the drain outlet in time, and minimize the possibility of water being discharged with the stones when the screen box is discharged, thus avoiding poor water removal effect.
[0033] like Figures 1-2 As shown, the upper surface of the filter structure 3 is provided with multiple water collection troughs 302, and the drain outlet 301 is located at the bottom of the water collection troughs 302. The water collection troughs 302 located in the aggregate area can collect the water mixed in the stone in advance, and at the same time play a guiding role, so that the water can smoothly enter the drain outlet 301, and avoid the water in the stone from sliding down the filter structure 3 and concentrating at the bottom of the filter structure 3, which would prevent it from being discharged smoothly from the drain pipe 2.
[0034] like Figures 3-4 As shown, the screen box 1 is provided with a support member 401 for installing the filter structure 3. The support member 401 is fixedly connected inside the screen box 1. Several first connectors 402 are installed on the top of the support member 401. Second connectors 403 are installed on the first connectors 402. A connecting rod 4041 is installed on the top of the second connector 403. A locking block 4042 is installed at one end of the connecting rod 4041. The bottom of the filter structure 3 has a connecting groove 305 that matches the locking block 4042. The connecting groove 305 is clearance-fitted with the connecting rod 4041 and the locking block 4042.
[0035] Specifically, during the vibration process of the vibrating mechanism driving the screen box 1 to vibrate, the filter structure 3 will undergo a certain deformation as the screen box 1 vibrates. The allowance between the connecting rod 4041 and the locking block 4042 allows the filter structure 3 to deform normally, resulting in a stronger vibration effect and a better dewatering effect. At the same time, the shape of the locking block 4042 limits the deformation of the filter structure 3, so as to avoid excessive deformation of the filter structure 3 and affect its lifespan.
[0036] like Figures 3-4 As shown, a pad 405 is installed on the side of the second connector 403 near the water filter structure 3. After the water filter structure 3 deforms downward and collides with the pad 405, the pad 405 can bounce the water filter structure 3 back, which to a certain extent promotes the vibration effect of the water filter structure 3 and helps to shake the water out of the stone.
[0037] As Figure 7 shown, the first connecting piece 402 is installed with a reinforcing block 4021 on one side. The inclined reinforcing block 4021 supports the first connecting piece 402. When the water filtering structure 3 contacts the cushion block 405 downward and the impact force is large, the reinforcing block 4021 and the L-shaped first connecting piece 402 form a stable triangular structure, which to some extent avoids the breakage of the first connecting piece 402.
[0038] As Figures 1-6 shown, the water filtering structure 3 is installed with a reinforcing assembly to make the connection between the water filtering structure 3 and the sieve box 1 more stable. The reinforcing assembly includes a plurality of fastening blocks 303, which are symmetrically installed on both sides of the water filtering structure 3. The inside of the sieve box 1 is installed with a fixing piece 304 matched with the fastening block 303. The fixing piece 304 can be fixed on the inside of the sieve box 1 by bolts. When there are more stones on the water filtering structure 3, the friction of the stones makes the water filtering structure 3 have a downward trend. The fixing piece 304 limits the position of the water filtering structure 3 through the fastening block 303, so that the position of the water filtering structure 3 is stable, and the breakage of the connecting assembly is avoided as much as possible, so that the water filtering structure 3 falls off from the sieve box 1.
[0039] As Figure 6 shown, the end of the fastening block 303 close to the dehydration area gradually shrinks, and the outer wall of the fastening block 303 is in close contact with the fixing piece 304. When there are more stones on the water filtering structure 3, the water filtering structure 3 gradually moves downward, and the fastening block 303 moves downward and gradually engages with the fixing piece 304, thereby limiting the position of the fastening block 303 and reducing the possibility of the water filtering structure 3 falling off from the sieve box 1 as much as possible.
[0040] During use, the stones in the sand and gravel storage bin fall onto the water filtering structure 3, and the stones move downward with the vibration of the sieve box 1 to complete the feeding. At the same time, with the vibration of the sieve box 1, the water in the stones is concentrated in the water collecting groove 302 and then enters the drainage port 301, and is discharged from the drainage pipe 2 through the drainage channel, so that the vibration feeding sieve with dehydration and screening function completes the feeding and drainage process at the same time, and reduces the equipment maintenance and operation cost.
[0041] When there are more stones, the water filtering structure 3 and the fastening block 303 slide downward, and the fixing piece 304 limits the position of the fastening block 303 to avoid the water filtering structure 3 from falling off from the sieve box 1 due to large force as much as possible.
[0042] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
