[0031] Embodiment 1
[0032] Referring to Figure 1 - Figure 3 , which is the first embodiment of the present utility model, provides a sand screening device. This device includes: a driving unit 100, including a top plate 101 and a driving component 102 disposed on the top of the top plate 101. The top plate 101 supports the driving component 102 on the top and can fix the interior at the same time, and installs and fixes the position of the driving component 102;
[0033] a screening unit 200, including a screening component 201 disposed on the driving component 102. The screening component 201 connected to the output end of the driving component 102 can screen and filter the sand and soil transported into the screening component 201; and,
[0034] a filtering and storage unit 300, including a filtering component 301 disposed at the bottom of the top plate 101, a fixed support frame 302 disposed on the outer wall of the filtering component 301, and a universal wheel 303 disposed at the bottom of the fixed support frame 302. The support frame 302 can fixedly support the filtering component 301 and its entirety, and the filtering component 301 intercepts the sand and soil that has been screened inside. The universal wheel 303 at the bottom enables the device to be moved for convenient use.
[0035] Among them, the driving component 102 includes a motor 102a arranged on the top of the top plate 101, an eccentric disk 102b arranged at the output end of the motor 102a, and a rotating connecting rod 102c arranged at the bottom of the eccentric disk 102b. By the motor 102a, the eccentric disk 102b starts to rotate, and then drives the rotating connecting rod 102c and the screening component 201 to move, so as to realize the screening work of the sandy soil.
[0036] During use, the operator opens the driving component 102 to put the sandy soil into the equipment. The sandy soil falls on the surface of the double-layer sieve plate 201a. The motor 102a inside the driving component 102 is started to make the eccentric disk 102b start to rotate. The eccentric disk 102b makes the rotating connecting rod 102c drive the screening component 201 to shake together, so that the double-layer sieve plate 201a can start to screen the sandy soil on the surface. And the inner screen of the double-layer sieve plate 201a is smaller than the outer screen, so that it can be screened twice in one operation.
[0037] Through the screening of the double-layer sieve plate 201a, all the larger stones and impurities are intercepted on the surface of the double-layer sieve plate 201a. The screened sandy soil falls on the double-layer sieve plate 201g at the bottom. The double-layer sieve plate 201a makes the double-layer sieve plate 201g also start to move in the opposite direction to separate the large-particle impurities on the surface of the sandy soil again for secondary screening. After the screening is completed, the sandy soil falls into the filtering and storage unit 300 through the double-layer sieve plate 201g. The filtering component 301 filters and intercepts the screened sandy soil again to obtain the screened and filtered sandy soil. Finally, the storage box inside the filtering and storage unit 300 collects and uses the sandy soil, so that the sandy soil can be fully screened and filtered, and the impurity content in the sandy soil is greatly reduced.
[0038] Embodiment 2
[0039] Refer to Figure 1 - Figure 4 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the screening component 201 includes a double-layer sieve plate 201a arranged at one end of the rotating connecting rod 102c, a rotating slide rod 201b rotatably arranged on both sides of the double-layer sieve plate 201a, a sliding sleeve 201c slidably arranged at the bottom of the rotating slide rod 201b, and a rotating slide rod 201e slidably arranged at the bottom end inside the sliding sleeve 201c. The double-layer sieve plate 201a connected by the rotating connecting rod 102c on the screening component 201 preliminarily screens and filters the incoming sandy soil.
[0040] Compared with Embodiment 1, further, a double-layer sieve plate 201g is rotatably arranged on the inner wall of the rotating slide rod two 201e, and the double-layer sieve plate 201g cooperates with the double-layer sieve plate 201a. While screening the sandy soil by the rotating slide rod one 201e, due to the cooperation of the slide rod one 201b and the rotating slide rod two 201e, the double-layer sieve plate 201g also starts to move and cooperate with the double-layer sieve plate 201a to start screening the falling sandy soil.
[0041] Wherein, a return spring 201d is arranged inside the sliding sleeve 201c, and the top of the return spring 201d is connected to the rotating slide rod one 201b, and the bottom is connected to the rotating slide rod one 201e. While the double-layer sieve plate 201g and the double-layer sieve plate 201a are screening, they are buffered and adjusted through the sliding sleeve 201c and the internal return spring 201d.
[0042] Further, fixed moving shafts 201f are rotatably arranged on both sides of the double-layer sieve plate 201a and the double-layer sieve plate 201g. The fixed moving shafts 201f connecting the double-layer sieve plate 201a and the double-layer sieve plate 201g stabilize and support the screening of the double-layer sieve plate 201a and the double-layer sieve plate 201g.
[0043] During use, when screening the sandy soil, the sandy soil is conveyed into the interior of the housing 301a and falls on the surface of the double-layer sieve plate 201a. Driven by the motor 102a inside the driving assembly 102, the double-layer sieve plate 201a moves, starts to shake the sandy soil on the surface to start screening and connect the large impurities. At the same time, because the double-layer sieve plate 201a is a double-layer integrated structure, the inner layer also moves together through the vibration of the bottom layer to screen the sandy soil so that the impurities can be intercepted, and the impurities are conveyed into the impurity discharge port 202 through shaking for impurity collection by the storage box 301b.
[0044] After preliminary screening, the sandy soil falls on the double-layer sieve plate 201g. The movement of the double-layer sieve plate 201a causes the rotating slide rod one 201b to drive the rotating slide rod two 201e to move in the opposite direction. While the rotating slide rod one 201e is screening the sandy soil, the rotating slide rod two 201e can cooperate to make the double-layer sieve plate 201g also start to move and start screening the falling sandy soil. At the same time, it is buffered by the return spring 201d inside the sliding sleeve 201c, and the fixed moving shaft 201f is moved and limited in the moving chute 301d, so that not only can the sandy soil be screened more carefully, but also the impurities in the sandy soil can be intercepted and conveyed and separated through its own movement, and it can also effectively prevent stones or impurities from blocking the sieve mesh for screening and affecting the screening efficiency.
[0045] The remaining structure is the same as that of Embodiment 1.
[0046] Embodiment 3
[0047] Refer to Figure 1 - Figure 6 , which is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that the filtering component 301 includes a housing 301a provided at the bottom of the top plate 101, and a storage box 301b slidably provided on the outer wall of the housing 301a. The top plate 101 and the housing 301a inside the filtering component 301 can support and fix the whole.
[0048] Compared with Embodiment 2, further, a filtering pull plate 301c is provided inside the storage box 301b, and an impurity discharge port 202 is provided on the outer wall of the housing 301a, and the impurity discharge port 202 cooperates with the storage box 301b. The filtering pull plate 301c inside the storage box 301b can filter the screened sand once to prevent the sand from containing remaining impurities and intercept them, and the screened sand falls to the bottom for collection after the screening and filtering are completed.
[0049] Wherein, a moving sliding groove 301d is provided inside the housing 301a, and the fixed moving shaft 201f slides inside the moving sliding groove 301d. The moving sliding groove 301d inside the housing 301a can limit and support the fixed moving shaft 201f when it moves.
[0050] During the use process, when collecting the screened sand, after double screening by the double-layer sieve plate one 201a and the double-layer sieve plate two 201g inside the housing 301a, all impurities and stones are screened and intercepted, and separated. The screened sand is conveyed into the storage box 301b, and the screened sand is filtered again by the filtering pull plate 301c inside the storage box 301b to prevent small particle residues from being contained in the screened sand and intercept them. After the screening and filtering are completed, the sand falls to the bottom for collection and storage, and the separated impurities can be collected and uniformly processed by pulling the filtering pull plate 301c. It can effectively make the larger stones inside the screened sand remain in the screening device, which is not convenient to quickly take out the stones, and easily causes the larger stones to block the sieve mesh for screening and affect the screening efficiency.
[0051] The remaining structure is the same as that of Embodiment 2.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
