Description

Technical Field

[0001] The utility model relates to the technical field of sand and gravel filtering, in particular to a sand and gravel filtering device. Background Art

[0002] Sand and gravel refer to a loose mixture of sand particles and crushed stone. During the processing of sand and gravel, it is necessary to use a filtering device to screen the sand and gravel to remove impurities in the sand and gravel and improve the quality of sand and gravel.

[0003] After searching, it was found that the authorized Chinese patent announcement number is CN 218743211 U, which discloses a sand and gravel filtering device, including a screening device, a connecting frame is fixedly connected to the screening device, and two vertical plates are fixedly connected to the side of the connecting frame. The staff can use a bucket, a lifting assembly, a rotating assembly and an extension assembly to load the sand and gravel. The loading process does not require much physical strength and does not require frequent bending and straightening, thereby reducing the labor workload of the workers. Each time loading can dump more sand and gravel into the screening device, thereby improving the processing efficiency of sand and gravel.

[0004] The sand and gravel filtering device in the above patent still has certain shortcomings. Most of the existing sand and gravel filtering devices are filtered through a screen. However, before screening and filtration, since the sand and gravel are often piled up for a long time, some of the sand and gravel will clump due to accumulation, and some of the sand and gravel will still have certain ribbon filaments remaining inside, which can easily cause blockage and entanglement of the filter, greatly reducing the sand and gravel filtering efficiency of the filter, and the processing efficiency is low, which is inconvenient for users to use.

The ends of the crushing rollers 602 are rotatably connected to the inner wall of the sand and gravel filtering bin 1 through the arranged transmission rods 604.

[0029] One end of the transmission rod 604 rotates and penetrates the inner wall of the sand and gravel filter bin 1. A belt drive wheel 605 is provided at the end of the transmission rod 604. The two belt drive wheels 605 are connected to each other through a transmission belt 606. A driving motor 607 is provided at the end of the transmission rod 604.

[0030] The silk thread collecting assembly 7 comprises two drop baffles 701 symmetrically arranged below the crushing roller 602, the ends of the two drop baffles 701 are hingedly connected, a plurality of drop through holes 702 are evenly opened on the drop baffles 701, two filament intercepting columns 703 are vertically arranged on the sides of the drop through holes 702, two side wall openings 704 are symmetrically opened on the left and right sides of the sand and gravel filtering bin 1, the bottom ends of the drop baffles 701 extend into the side wall opening 704, and the bottom ends of the drop baffles 701 are hingedly provided with end fixing plates 705.

[0031] Two side grooves 706 are symmetrically provided on the outer wall of the sand and gravel filter bin 1, a sliding inner cavity 707 is provided on the inner wall of the side groove 706, a fixed interference rod 708 is slidably inserted in the sliding inner cavity 707, an interference groove 709 is provided on the top of the end fixing plate 705, the bottom end of the fixed interference rod 708 extends into the side wall opening 704 and interferes with the interference groove 709, a limiting connecting rod 710 is vertically arranged at the bending part of the fixed interference rod 708, and a limiting groove 711 is provided on the top wall of the sliding inner cavity 707.

One end of the resistance spring 712 is connected to the limiting connecting rod 710, and the other end of the resistance spring 712 is connected to the inner wall of the sliding inner cavity 707.

[0033] Embodiment 2: The difference between this embodiment and embodiment 1 is that the junction between the ends of the two blanking baffles 701 is in an upward arched shape.

[0034] The sand and gravel crushed by the crushing rods 603 on the two crushing rollers 602 fall onto the material dropping baffle 701 and can quickly pass through the material dropping through hole 702 opened on the material dropping baffle 701 .

[0035] Embodiment 3: The difference between this embodiment and embodiment 1 is that the side of the end fixing plate 705 is inserted into the side wall opening 704, and a handle is provided on the other side of the end fixing plate 705.

[0036] This makes it more convenient to pull the blanking baffle 701 connected to the end of the end fixing plate 705 .

[0037] Embodiment 4: The difference between this embodiment and embodiment 1 is that the fixed abutment rod 708 is in an L shape for easy pulling.

[0038] This allows the fixed interference rod 708 to more conveniently penetrate the sliding inner cavity 707 and extend into the side wall opening 704 to interfere with the interference sliding groove 709 .

[0039] In this embodiment, since most of the existing sand and gravel filtering devices filter through a screen, before screening and filtration, the sand and gravel are often piled up for a long time, some of the sand and gravel will clump due to accumulation, and some of the sand and gravel will still have certain ribbon filaments remaining inside, which can easily cause blockage and entanglement in the filter, greatly reducing the sand and gravel filtering efficiency of the filter, the processing efficiency is low, and it is inconvenient for users to use.

[0040] In summary, in the specific implementation, when the user needs to filter the impurities in the sand and gravel, the user first starts the drive motor 607, so that the drive motor 607 drives the transmission rod 604 to rotate, and the transmission rod 604 drives the crushing rod 603 to rotate by driving the crushing roller 602, so that the sand and gravel clumps put into the sand and gravel filter bin 1 through the feed hopper 5 are hit and broken, ensuring that the sand and gravel entering the filter box 2 set at the bottom of the sand and gravel filter bin 1 do not have large lumps.

[0041] The crushed sand and gravel will continue to fall downward and fall onto the two arched drop baffles 701. Since a number of drop holes 702 are evenly arranged on the drop baffles 701, and the gap between each adjacent drop hole 702 is small, the hole of the drop hole 702 is large, and the falling crushed sand and gravel will not be affected.

[0042] The filament intercepting column 703 arranged on the side of the blanking through hole 702 can effectively intercept the ribbon filaments on the filament intercepting column 703 because the ribbon filaments contained in the sand and gravel are generally long, and can be pierced and blocked by the filament intercepting column 703, thereby ensuring that the inside of the sand and gravel entering the filter box 2 is cleaner.

[0043] As for cleaning the filaments intercepted on the filament interception column 703, the user can pull the fixed resistance rod 708 so that the bottom end of the fixed resistance rod 708 no longer interferes with the end fixed plate 705, and then by pulling the end fixed plate 705, the falling material baffle 701 can be quickly and conveniently pulled out of the sand and gravel filter bin 1, so as to clean the filaments intercepted on its surface and facilitate the next use.
