Description

Technical Field

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

[0002] In the field of construction, sand and gravel are usually used as aggregates and mixed with cement to make concrete. When using sand and gravel for construction, the sand and gravel are often mixed with impurities such as large stones or long branches. Therefore, the sand and gravel need to be cleaned before use.

[0003] When filtering sand and gravel on a construction site, a unified filtering operation is usually performed first. The filtered sand and gravel will be piled on the ground. When used later, workers need to shovel them into a cart for transportation, which is troublesome. Based on this, a patent application number 202322394179.0 discloses a rapid sand and gravel filtering device. The disclosed filtering device is described as follows: "When in use, the sand and gravel are shoveled onto the top of the filtering mechanism by a shovel. The sand and gravel fall onto the top of the cart after being filtered by the filtering mechanism. The filtered impurities slide down the cart under the action of gravity, and the user transports the sand and gravel to the destination. After the ground is grounded, the limit of the filtering device is released by the limiting mechanism, and the sand and gravel can be poured out by the cart. This arrangement ensures that the sand and gravel are filtered once when they are taken, which not only saves the time of unified filtration, but also ensures that the sand and gravel taken do not contain impurities, fully reflecting the practicality of the device. However, in actual use, when the cart equipped with the filtering mechanism is dumping sand and gravel, the filtering mechanism is above the sand and gravel bucket, which will block the dumping of sand and gravel and affect the discharge of materials. If the filtering mechanism is disassembled and assembled to achieve screening, filtering and discharge, it is more troublesome. For this reason, we propose a sand and gravel rapid filtering device.

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

[0032] Embodiment one

[0033] Please refer to Figure 1-Figure 3 The present application provides a technical solution: a sandstone rapid impurity filtering device, which comprises a vehicle body 1, a sandstone hopper 2 is fixed to the upper end surface of the vehicle body 1, and a vibrating screen assembly 3 is arranged on the upper end surface of the sandstone hopper 2. The vibrating screen assembly 3 comprises a first screen 301 and a second screen 302, the first screen 301 and the second screen 302 are hingedly connected, a vibrating motor 303 is installed on the lower end surface of the first screen 301, the second screen 302 has a screening state and a discharging state, when the second screen 302 is in the screening state, the second screen 302 and the first screen 301 belong to the same plane, and the second screen 302 is in a fixed state; when the second screen 302 is in the discharging state, the second screen 302 can be automatically turned over, and when the sandstone in the sandstone hopper 2 is poured out, the second screen 302 can be turned over to increase the size of the discharge port.

[0034] The vehicle body 1 described above comprises a bottom supporting plate 101 and a moving wheel 102, the moving wheel 102 is installed on the lower end surface of the front side of the bottom supporting plate 101, and the moving wheel 102 can be provided with one or two. When the moving wheel 102 is one, it is installed on the lower end surface of the front side of the middle of the bottom supporting plate 101, and when the moving wheel 102 is two, it is symmetrically installed on the lower end surface of the front side of the bottom supporting plate 101. A supporting frame 103 is installed on the rear side of the lower end surface of the bottom supporting plate 101, the lower end surface of the supporting frame 103 is lower than the bottom end of the moving wheel 102, so that when the sandstone hopper 2 is placed, the front side of the sandstone hopper 2 is inclined downward, and the rear side of the bottom supporting plate 101 is connected with a push-pull handrail 104.

[0035] In addition, please refer to Figure 3As shown, the sand and gravel rapid filtering device also includes an elastic connector 4 and a limiting assembly 5, wherein a plurality of elastic connectors 4 are provided, and a plurality of elastic connectors 4 are evenly installed at the edge of the upper end surface of the sand and gravel bucket 2, the first screen 301 is fixedly connected to the top of the elastic connector 4, the second screen 302 is mounted on the elastic connector 4, and the second screen 302 is mounted so as to be able to flip along the hinged part, and the limiting assembly 5 is used to limit the flipping of the second screen 302 when the second screen 302 is in a screening state to ensure a stable screening state.

[0036] In the specific implementation of the present invention, see Figure 4 As shown, the elastic connecting member 4 includes a first spring 403 , and the first spring 403 is arranged between the sand bucket 2 and the vibrating screen assembly 3 .

[0037] In a specific embodiment of the present invention, the limiting assembly 5 includes a first connecting portion 51 and a second connecting portion 52 , and the first connecting portion 51 and the second connecting portion 52 are detachably connected.

[0038] Through the above, in actual use, the limiting component 5 can be used to put the second screen 302 in a screening state, and then the vibration motor 303 can be started. The staff shovels the sand and gravel to the top of the first screen 301 and the second screen 302 with a shovel, and through the vibration screen, and in conjunction with the first spring 403, the smaller sand and gravel can fall into the sand and gravel bucket 2, and the larger sand and gravel can slide down from the first screen 301 and the second screen 302 with manual cleaning.

[0039] After the gravel bucket 2 is full of sand and gravel, the staff can pull the vehicle body 1 to move it to the required area, and then release the restriction of the limit component 5 on the second screen 302, and then use the push-pull handrail 104 to lift the rear end of the gravel bucket 2, and the sand and gravel in the gravel bucket 2 can be poured out from the front side of the gravel bucket 2. When the sand and gravel in the gravel bucket 2 are poured out, the second screen 302 in the discharging state can be flipped outward under the impact of the sand and gravel, thereby expanding the size of the discharge port to avoid obstruction, making it more convenient and quick to pour out the sand and gravel.

[0040] Among them, combined Figure 5 and Figure 6 As shown, the first connecting part 51 includes a first fixed plate 511 and a hinge bar 513. The first fixed plate 511 is fixed to the upper end of the front side of the sand and gravel bucket 2, and a second groove 512 is provided on the first fixed plate 511. One end of the hinge bar 513 is hinged in the second groove 512, and the other end of the hinge bar 513 is fixed with an embedded block 514 facing the sand and gravel bucket 2. The embedded block 514 is provided with a third groove 516 on at least one side, and a second spring 517 is connected to the inside of the third groove 516. A movable stopper 515 is installed at the free end of the second spring 517. Both sides of the outer wall of the movable stopper 515 are integrally formed with a pushing slope 518.

[0041] Combine Figure 7 As shown, the second connecting part 52 includes a second fixing plate 521, and the upper end surface of the second fixing plate 521 is provided with an embedding groove 522. The front end width of the embedding groove 522 is smaller than its internal width, and both sides of the front end of the embedding groove 522 are integrally formed as an entry and exit inclined surface 523.

[0042] Through the above, when it is necessary to screen sand and gravel, the second screen 302 is first placed in the same plane, and then the hinged bar 513 hinged in the second groove 512 can be flipped over to flip the embedded block 514 to be embedded in the embedded groove 522. When the embedded block 514 reaches the outer end of the embedded groove 522, as force is applied, the movable stopper 515 squeezes the second spring 517, and the movable stopper 515 retracts into the third groove 516. After the movable stopper 515 passes through the front end of the embedded groove 522, the movable stopper 515 enters the inner end of the wider embedded groove 522. At this time, the movable stopper 515 moves out of the third groove 516, which can play a blocking role. When not affected by external force, the movable stopper 515 is not easy to separate from the embedded groove 522.

[0043] When it is necessary to release the restriction on the second screen 302 , the upper end of the hinge bar 513 can be directly pulled outward to disengage the movable stopper 515 from the embedding groove 522 .

[0044] The push slope 518 and the entry and exit slope 523 cooperate with each other to reduce the resistance when the first connecting part 51 and the second connecting part 52 are connected and separated.

[0045] Also, see Figure 1 and Figure 2 As shown, baffles 6 are installed on both sides and the rear side of the outer wall of the sand and gravel bucket 2, and the upper end surface of the baffle 6 is higher than the upper end surface of the first screen 301.

[0046] Specifically, when the staff shovels the sand and gravel onto the first screen 301 and the second screen 302 for vibrating screening, the baffle 6 can prevent the sand and gravel from falling from both sides and the rear side.

[0047] Example 2

[0048] The difference between this embodiment and the first embodiment is that, see Figure 4As shown, the elastic connecting member 4 also includes a column 401, and a first groove 402 is opened axially on the column 401. The bottom end of the first spring 403 is connected to the bottom of the first groove 402, and a connecting plate 405 is fixed to the top of the first spring 403. The connecting plate 405 is preferably a circular plate, and the diameter of the connecting plate 405 does not exceed the inner diameter of the first groove 402. In the natural state of the first spring 403, the distance between the lower end face of the connecting plate 405 and the upper end face of the column 401 is not less than the length of the column 401. The side wall of the connecting plate 405 is symmetrically fixed with a limiting strip 406, and the side wall of the first groove 402 is symmetrically opened with a limiting groove 404, and the limiting strip 406 is inserted and matched with the limiting groove 404.

[0049] As mentioned above, when vibrating the screen, as the vibrating screen assembly 3 moves up and down, the limit bar 406 can move up and down along the limit groove 404, and cooperate with the column 401 with the first groove 402 to limit the first spring 403, which can prevent the first spring 403 from bending during the vibrating screen process, thereby ensuring the vibrating screen effect.
