Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction engineering equipment technology, and in particular to a material screening machine. Background Technology
[0002] Currently, aggregate screening and testing mainly rely on mechanical vibrating screens or manual shaking screens. While existing mechanical vibrating screens can speed up the screening process to some extent, they do not provide a direct visual view of the dynamic process of aggregate separation within the screen. For aggregate screening and testing, such as for concrete, multiple screenings are required to separate aggregates of different particle sizes, thereby determining whether the aggregate mix proportions meet requirements. Therefore, this process involves multiple steps, and the screening results are susceptible to unexpected influencing factors. For example, the inability to observe the screening process in real time makes it difficult to determine whether screening is sufficient and to promptly detect potential blockages or other abnormalities. Utility Model Content

The vibrating base is disposed on the vibrating device, and the vibrating base has multiple stepped surfaces for mounting the screening box, with the screening box distributed on the stepped surfaces.
[0005] The screening box includes a box body and a screening screen disposed inside the box body, wherein the box body is made of transparent material;
[0006] The top of the box is provided with a feed inlet, and the side wall of the box is provided with a discharge outlet. After the collected material is screened by the screening screen, it flows out from the discharge outlet.
[0007] Between adjacent screening boxes, the discharge port of the screening box at the higher position is the high-position discharge port, and the inlet of the screening box at the lower position is the low-position inlet.
[0008] The high-level discharge port is located above the low-level inlet port, so that after the aggregate falls into the highest screening box, it flows downward through the screening screens of each screening box.
[0009] From high to low, the aperture of the screening screen in the screening box gradually decreases.
[0010] As an improvement to the above solution, the inner wall of the box is provided with support edges on both sides for supporting the screening screen, so as to support the two sides of the screening screen respectively.
[0011] As an improvement to the above scheme, a weighing device is provided on one side of each screening box, and a weighing port corresponding to the weighing device is provided on the side wall of the box body, so that one end of the screening screen can pass through to the weighing device.
[0012] As an improvement to the above solution, the weighing port is provided corresponding to the support edge, so that the screening screen passes through the weighing port along the support edge.
[0013] As an improvement to the above solution, the screening box further includes a baffle for closing the weighing port. The side wall of the box is provided with a slot for inserting the baffle. The baffle is inserted into the slot to block the weighing port.
[0014] As an improvement to the above solution, the screening box is provided with a flow guiding inclined surface, which is located below the screening screen;
[0015] After being screened by the screening mesh, the aggregate falls onto the inclined guide surface, the lowest point of which corresponds to the discharge port, so as to guide the aggregate out of the discharge port.
[0016] As an improvement to the above solution, the support edge includes a horizontal support section and an inclined support section. The two sides of the horizontal support section are connected to the inner wall of the box and the inclined support section, respectively.

[0017] As an improvement to the above solution, the enclosure is made of plexiglass or transparent plastic.
[0018] As an improvement to the above solution, the vibrating base is provided with a material collection and recycling trough, and the discharge port of the lowest screening box is located on the upper side of the material collection and recycling trough, so that the screened material flows into the material collection and recycling trough.
[0019] As an improvement to the above solution, the box at the highest position is equipped with an openable lid to cover the feed inlet;
[0020] One end of the lid is hinged to the box body.
[0021] Implementing this utility model has the following beneficial effects:
[0022] This utility model discloses a material screening machine, including a vibrating base, screening boxes, and a vibrating device for vibrating the vibrating base. The vibrating base is disposed on the vibrating device, and the vibrating base has multiple stepped surfaces for mounting the screening boxes. The screening boxes are distributed on the stepped surfaces, so the vibrating device can vibrate all screening boxes synchronously by vibrating the vibrating base.
[0023] The screening box includes a box body and a screening screen disposed inside the box body. The box body is made of transparent material; therefore, the operator can observe the screening status of the aggregate at any time to ensure that the aggregate in each screening box is fully screened, thereby improving the accuracy of the test.
[0024] The top of the screening box has a feed inlet, and the side wall of the screening box has a discharge outlet. After being screened by the screening mesh, the aggregate flows out from the discharge outlet. Between adjacent screening boxes, the discharge outlet of the screening box at the higher position is the high-position discharge outlet, and the feed inlet of the screening box at the lower position is the low-position feed inlet. The high-position discharge outlet is located above the low-position feed inlet. From high to low, the aperture of the screening mesh of the screening box gradually decreases. Therefore, after the aggregate is introduced into the highest-position screening box, it will flow downwards through the screening mesh of each screening box, thereby automatically screening out aggregates of different particle sizes and saving multiple screening operations.

[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0030] See Figure 1 and Figure 2 This utility model provides a material screening machine, including a vibrating base 1, a screening box 2, and a vibrating device 3 for vibrating the vibrating base 1. The vibrating base 1 is disposed on the vibrating device 3. The vibrating base 1 is provided with multiple stepped surfaces 11 for mounting the screening box 2. The screening box 2 is distributed on the stepped surfaces 11.
[0031] The screening box 2 includes a box body 21 and a screening screen 22 disposed inside the box body 21, wherein the box body 21 is made of transparent material;
[0032] The top of the box 21 is provided with a feed inlet 211, and the side wall of the box 21 is provided with a discharge outlet 212. After the collected material is screened by the screening screen 22, it flows out from the discharge outlet 212.
[0033] Between adjacent screening boxes 2, the discharge port 212 of the screening box 2 at the higher position is the high-position discharge port, and the inlet port 211 of the screening box 2 at the lower position is the low-position inlet port.
[0034] The high-level discharge port is located above the low-level inlet, so that after the aggregate falls into the highest screening box 2, it flows downwards through the screening mesh 22 of each screening box 2; from high to low, the aperture of the screening mesh 22 of the screening box 2 gradually decreases. Preferably, the box body 21 is made of plexiglass or transparent plastic. The vibration device is existing technology, which generally uses a motor to drive an eccentric wheel to generate a stable vibration frequency and amplitude.
[0035] Specifically, see Figure 3 The inner wall of the housing 21 is provided with support edges 213 on both sides to support the screening screen 22, so as to support the two sides of the screening screen 22 respectively. Therefore, the operator can directly remove or move the screening screen 22, thereby facilitating the collection and weighing of particles on the screening screen 22.
[0036] Furthermore, to simplify and improve weighing efficiency, a weighing device 4 is provided on one side of each screening box 2. The side wall of the box body 21 is provided with a weighing port 214 corresponding to the weighing device 4, allowing one end of the screening mesh 22 to pass through onto the weighing device 4. Therefore, after screening, the operator can pass one end of the screening mesh 22 through the weighing port 214 and use the screening mesh 22 itself as a discharge channel to directly sweep the particles on the screening mesh 22 onto the weighing device 4, thereby simplifying the collection, transfer, and weighing of particles and achieving rapid weighing.
[0037] More preferably, the weighing port 214 is correspondingly arranged with the support edge 213 so that the screening screen 22 passes through the weighing port 214 along the support edge 213. Therefore, when weighing is required, it is only necessary to push the screening screen 22 horizontally, without the need for additional physical labor such as lifting the screening screen 22.
[0038] See Figure 4 To prevent aggregate from escaping from the weighing port 214 during the vibratory screening process, the screening box 2 also includes a baffle plate 23 for sealing the weighing port 214. The side wall of the box body 21 has an insertion groove 215 for inserting the baffle plate 23. The baffle plate 23 is inserted into the insertion groove 215 to block the weighing port 214. Therefore, when weighing is required, the baffle plate 23 can be lifted or removed, which is convenient and quick.
[0039] On the other hand, to facilitate the sweeping of particles from the screening mesh 22 onto the weighing device 4, the support edge 213 includes a horizontal support section 2131 and an inclined support section 2132. The two sides of the horizontal support section 2131 are connected to the inner wall of the housing 21 and the inclined support section 2132, respectively. The top surface of the horizontal support section 2131 is horizontal, and the top surface of the inclined support section 2132 is inclined downwards. The screening mesh 22 is generally made of a material or structure with a certain elastic deformation capacity, such as a thin metal mesh or plastic mesh. Therefore, when the aggregate falls onto the screening mesh 22, it will bend the mesh, causing the screened particles to gather towards the center of the mesh 22, making it easier for the operator to sweep the particles onto the weighing device 4. The width design of the horizontal support section 2131 and the inclined support section 2132 can be adjusted according to the width of the screening mesh 22 and the required load-bearing capacity. That is, the wider the screening mesh 22, the wider the horizontal support section 2131 should be, to prevent the screening mesh 22 from falling off due to loss of support from the horizontal support section 2131 after excessive drooping and bending. Accordingly, the width of the horizontal support section 2131 can be preset so that the screening mesh 22 will bend to a certain extent during the process, but the maximum bending amplitude of the screening mesh 22 is limited by the inclined support section 2132 while providing support to the screening mesh 22, thereby ensuring that the screening mesh 22 will not fall off due to excessive bending.
[0040] In order to reduce the retention of some aggregate in the screening box 2, the screening box 2 is provided with a guide inclined surface 24, which is located below the screening screen 22;
[0041] After being screened by the screening screen 22, the aggregate falls onto the guide inclined surface 24. The lowest point of the guide inclined surface 24 corresponds to the discharge port 212 to guide the aggregate out of the discharge port 212.
[0042] To facilitate the recycling and processing of the screened aggregate, the vibrating base 1 is provided with an aggregate recycling trough 12. The discharge port 212 of the lowest screening box 2 is located on the upper side of the aggregate recycling trough 12 so that the screened aggregate flows into the aggregate recycling trough 12.
[0043] On the other hand, based on the multi-level stepped surface 11 of the vibrating base 1, the screening box 2 at the highest position has a larger height, i.e., a higher center of gravity. During vibration, the amplitude of the aggregate swaying is relatively large. To prevent accidental escape of the aggregate and potential safety issues, the box body 21 at the highest position is equipped with an openable cover 25 to cover the feed inlet 211; one end of the cover is hinged to the box body 21. The cover 25 is closed after the aggregate has been completely introduced.
[0044] Correspondingly, the other screening boxes 2 can be equipped with boxes with lids, as long as the width of the lid is less than the width of the box body 21 by a preset distance, so as to form a feed inlet 211.
[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
