AI Technical Summary
In existing technologies, the finished product bin is prone to segregation of coarse and fine mixtures during the discharge process, resulting in an imbalance in the composition ratio of the finished product. Although existing guide steel plates can partially solve this problem, they affect the direction of movement of the fine mixture, leading to secondary segregation.
The guide unit is driven by a rotary power component. The guide plate is equipped with screen holes. The rotation direction is opposite to the discharge route. Fine mixture is allowed to pass through the screen holes, while coarse mixture is intercepted. The stability of the guide plate is ensured by the sliding groove and the limiting unit, thus achieving selective interception.
It significantly reduces the segregation of coarse and fine mixtures, ensuring that the coarse and fine mixtures are evenly stacked in the finished product bin, avoiding secondary segregation, and the guide plates can be replaced according to the specifications of the mixture, improving the adaptability of the equipment.

Technical Field
[0001] This utility model belongs to the field of transportation device technology, and particularly relates to a device used during loading or unloading, specifically a finished product warehouse anti-segregation device. Background Technology
[0002] Dry-mixed mortar is a type of building mortar that is precisely proportioned and uniformly mixed in a factory, then packaged in a dry state or transported to the construction site in bulk. It can be used directly by simply adding water and mixing according to the specified ratio. In the dry-mixed mortar industry, the discharge process from the finished product silo is a crucial step in removing the mixed finished dry-mixed mortar from the storage silo and transporting it to the packaging machine or bulk transport vehicle via conveying equipment. This process needs to ensure a smooth, stable, and segregation-free output of the material.
[0003] Segregation in finished product silos refers to the uneven separation of dry-mixed mortar stored in a silo due to differences in the physical properties of its components, such as uneven particle size, under the influence of gravity, airflow, or mechanical vibration. This separation leads to an imbalance in the proportion of mortar components at different locations within the silo, directly affecting the uniformity and workability of the final product. A typical example is the process of conveying the mixture into the finished product silo via a conveyor belt. At the end of the belt, i.e., the mixture outlet, coarse and fine mixtures easily separate due to inertia. The coarse mixture travels a longer parabolic path, resulting in more coarse mixture falling into the silo on the side farther from the belt, while fine mixture falls along the belt end towards the side closer to the belt. This clearly demonstrates the segregation of coarse and fine mixtures in the finished product silo.
[0004] To prevent segregation in the finished product silo, existing technologies typically involve uniformly mixing the coarse and fine aggregates. For example, Chinese utility model patent CN202380380U discloses a device for preventing segregation of finished product materials. The coarse and fine aggregates described in the paper are coarse and fine aggregates. This device uses guide steel plates to change the direction of the segregated coarse aggregate, directing it to the position where the fine aggregate falls. The coarse and fine aggregates are then evenly piled together, thus preventing segregation of the finished product in the finished product silo.
[0005] However, simply setting up guide plates also affects the direction of travel of the fine mixture, causing the fine mixture that should have been dispersed to a further distance to be pulled back to a closer distance, which is not conducive to the process of preventing segregation in the finished product warehouse. Utility Model Content
[0006] The purpose of this invention is to provide a finished product warehouse anti-segregation device that can improve the selective interception capability of coarse and fine mixtures and significantly reduce segregation.
[0007] The technical solution adopted by this utility model to solve the above problems is: a finished product silo anti-segregation device, including a finished product silo, a conveyor belt with the discharge end set at the inlet of the finished product silo, and a guide unit set at the discharge path at the discharge end, wherein:
[0008] The guiding unit includes a rotating power component, a rotating column disposed at the rotor end of the rotating power component, and several guide plates disposed on the rotating column; several sieve holes are disposed on the guide plates;
[0009] The rotation direction of the rotating power component makes the guide plate opposite to the conveying direction of the discharge route.
[0010] A further preferred technical solution is that: the rotating column is provided with a sliding groove for slidingly mounting the guide plate, and a limiting unit for abutting and restricting the guide plate to be located in the sliding groove.
[0011] A further preferred technical solution is that the width of the sliding groove opening is smaller than the width of the bottom end of the guide plate.
[0012] A further preferred technical solution is that: the rotating column has a threaded groove on its side end; the limiting unit includes an abutment column inserted into the sliding groove, a mounting plate for fixing the abutment column, a mounting hole set on the mounting plate and aligned with the opening of the sliding groove, and a fixing bolt passing through the mounting hole and screwed into the threaded groove.
[0013] A further preferred technical solution is that the abutment post is inserted into the sliding groove and directly abuts against the bottom end of the guide plate.
[0014] A further preferred technical solution is that the limiting unit also includes two half-rings sleeved on the rotating column, and a fixing plate set on the half-rings; the fixing plate is provided with fixing holes and a bolt kit for fixing the two aligned fixing holes together.
[0015] A further preferred technical solution is that: a limiting plate for insertion into the sliding groove is provided on the inner side of the half ring, and the abutting post abuts against the side of the limiting plate.
[0016] A further preferred technical solution is that the thickness of the limiting plate not set at the end of the half-ring is twice that of the limiting plate set at the end of the half-ring.
[0017] In summary, this utility model has the following advantages:
[0018] 1. This invention improves the selective interception capability of coarse and fine mixtures, significantly reducing segregation. Specifically, the guide plate is provided with sieve holes, the aperture of which allows fine mixtures to pass through while intercepting coarse mixtures. This allows the fine mixtures to pass through the sieve holes with minimal impact during operation, maintaining their original parabolic trajectory and falling to the far side of the finished product bin; while the coarse mixtures are intercepted by the guide plate and forcibly pulled back to the area near the material drop point of the conveyor belt. This selective separation ensures that the coarse and fine mixtures are evenly accumulated in the finished product bin, avoiding the secondary segregation problem caused by the guide plate simultaneously interfering with the coarse and fine mixtures in the prior art.
[0019] 2. This utility model features a sliding groove on the rotating column, allowing the guide plate to be modularly replaced via a sliding installation method. This enables users to select guide plates with corresponding sieve aperture diameters according to the specifications of different mixtures, without requiring overall device modification.
[0020] 3. The design of the limiting unit of this utility model effectively suppresses the radial and axial vibration of the guide plate and ensures the stability of the guide plate operation. Attached Figure Description

Detailed Implementation
[0036] The reason why the guide steel plate set in CN202380380U affects the travel direction of the fine mixture is that the guide steel plate is not selective enough for the coarse and fine mixtures. If the structure and operation mode of the guide steel plate can be further improved to make it selective for the coarse and fine mixtures, that is, only affecting the coarse mixture and minimizing its impact on the fine mixture, the anti-segregation process can be made more stable.
[0037] Based on this, the present disclosure proposes a finished product warehouse anti-segregation device, which aims to improve the selectivity of coarse and fine mixed materials.
[0038] The present invention will be specifically illustrated below with reference to embodiments:
[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example
[0040] refer to Figures 1-13 The finished product silo anti-segregation device includes a finished product silo 1, a conveyor belt 2 with its discharge end located at the inlet of the finished product silo 1, and a guide unit 3 located at the discharge path of the discharge end, wherein:
[0041] The guiding unit 3 includes a rotating power component 3.1, a rotating column 3.2 disposed at the rotor end of the rotating power component 3.1, and a plurality of guide plates 3.3 disposed on the rotating column 3.2; the guide plates 3.3 are provided with a plurality of sieve holes 3.3.1;
[0042] The rotation direction of the rotating power component 3.1 makes the guide plate 3.3 opposite to the conveying direction of the discharge route.
[0043] The finished product silo 1 is a vertical container for storing the mixed dry mortar, and has at least one top inlet. The remaining structure can take any known form. The conveyor belt 2 can be a belt conveyor or any known form similar to a belt conveyor. The conveyor belt 2 includes at least a conveyor belt and a drive roller. The conveyor belt can be made of rubber or any known material similar to rubber. The drive roller is driven by any known form of rotary power component, and the transmission connection between the drive roller and the conveyor belt can be achieved in any known form. No further limitations are imposed on any of the above-mentioned known forms in this embodiment.
[0044] The rotating power component 3.1 can be a motor with a rotor. As for the specific structure of the motor, the energy acquisition method, and the control method, any known method can be used, and no further restrictions are made in this embodiment.
[0045] The specific structure of guide plate 3.3 is as follows: Figures 2-4 The rectangular plate shown can also be other plate-shaped components with similar forms. The sieve aperture 3.3.1 penetrates the guide plate 3.3. The aperture of the sieve aperture 3.3.1 is such that it allows fine mixtures to pass through while intercepting coarse mixtures, thus affecting only the coarse mixtures and almost not the fine mixtures, improving the selectivity for intercepting both coarse and fine mixtures. The aperture of the sieve aperture 3.3.1 is selected according to the specific implementation process; in this embodiment, no further restrictions are placed on the size of the aperture of the sieve aperture 3.3.1.
[0046] The rotation direction of the rotating power component 3.1 causes the guide plate 3.3 to be opposite to the conveying direction of the discharge route, as shown in the reference. Figure 1 The arrow on the upper side of conveyor belt 2 indicates the discharge route, and the arrow on the upper side of guide unit 3 indicates the rotation direction of the rotating power component 3.1. It can be seen that the two arrows, distinguished by left and right, have opposite main directions. This allows the guide plate 3.3 to move towards the coarse and fine mixture, thus performing the screening process. Depending on the conveying direction of conveyor belt 2, the position of the rotating power component 3.1 can be selected to rotate clockwise or counterclockwise to ensure that the rotation direction of the rotating power component 3.1 is opposite to the conveying direction of the discharge route. This embodiment does not further limit whether the rotating power component 3.1 rotates clockwise or counterclockwise.
[0047] Furthermore, for coarse and fine mixtures of different specifications, the diameter of the required sieve aperture 3.3.1 needs to be adjusted. However, directly adjusting the sieve aperture 3.3.1 of the guide plate 3.3 is impractical. Therefore, setting guide plates 3.3 with different diameter sieve apertures 3.3.1 and then replacing the guide plates 3.3 is a feasible approach. Based on this, the rotating column 3.2 is provided with a sliding groove 3.2.1 for slidingly mounting the guide plate 3.3, and a limiting unit 4 for abutting and restricting the guide plate 3.3 to be located in the sliding groove 3.2.1.
[0048] The guide plate 3.3 is installed on the rotating column 3.2 by being inserted along the extending direction of the sliding groove 3.2.1. The number of sliding grooves 3.2.1 can be determined according to the number of guide plates 3.3 to be installed on the rotating column 3.2, for example, 2, 3, 4 or more. Figures 2-4 The previous illustration showed a rotating column 3.2 with four sliding grooves 3.2.1 simultaneously. This embodiment does not further limit the number of sliding grooves 3.2.1. The limiting unit 4, by inserting into and fixing itself into the sliding groove 3.2.1, fixes the guide plate 3.3, which is already installed in the sliding groove 3.2.1, along the extension direction of the sliding groove 3.2.1, preventing it from moving along that direction.
[0049] Furthermore, the guide plate 3.3, which slides into the sliding groove 3.2.1, needs to remain within the sliding groove 3.2.1 during operation and will not disengage due to rotational inertia. Therefore, the width of the opening of the sliding groove 3.2.1 is smaller than the width of the bottom end of the guide plate 3.3. (Reference) Figure 13 The present invention illustrates one form of the sliding groove 3.2.1 and the bottom end of the guide plate 3.3, both of which have a trapezoidal cross-section, so that the guide plate 3.3, which is slidably installed in the sliding groove 3.2.1, will not move in a direction perpendicular to the extension direction of the sliding groove 3.2.1. The present invention does not further restrict the form of the opening of the sliding groove 3.2.1 and the bottom end of the guide plate 3.3.
[0050] Furthermore, the rotating column 3.2 has a threaded groove 3.2.2 on its side end; the limiting unit 4 includes an abutment post 4.1 inserted into the sliding groove 3.2.1, a mounting plate 4.2 for fixing the abutment post 4.1, a mounting hole 4.3 on the mounting plate 4.2 aligned with the opening of the sliding groove 3.2.1, and a fixing bolt 4.4 passing through the mounting hole 4.3 and screwed into the threaded groove 3.2.2. In use, after the guide plate 3.3 is installed, the abutment post 4.1 is inserted into the corresponding sliding groove 3.2.1. At this time, the mounting hole 4.3 is also aligned with the threaded groove 3.2.2. The opening specifications of the threaded groove 3.2.2 are generally the same as the opening specifications of the mounting hole 4.3. After the fixing bolt 4.4 is screwed into the threaded groove 3.2.2, the mounting plate 4.2 is fixed. The disclosed forms of any of the known threaded groove 3.2.2, mounting hole 4.3, and fixing bolt 4.4 are not further limited in this embodiment.
[0051] Furthermore, in the first case, the abutment post 4.1 is inserted into the sliding groove 3.2.1 and directly abuts against the bottom end of the guide plate 3.3. When the abutment post 4.1 abuts against the side end of the bottom end of the guide plate 3.3, the mounting hole 4.3 is also aligned with the threaded groove 3.2.2, and can be fixed by the fixing bolt 4.4.
[0052] Furthermore, in the second case, the contact area between the abutment post 4.1 and the side end of the guide plate 3.3 is insufficient, which will cause the guide plate 3.3 to wobble slightly. Based on this, the limiting unit 4 also includes two half-rings 4.5 sleeved on the rotating post 3.2, and a fixing plate 4.6 disposed on the half-rings 4.5; the fixing plate 4.6 is provided with fixing holes 4.6.1, and a bolt kit 4.6.2 for fixing the two aligned fixing holes 4.6.1 together. (Refer to...) Figure 12 After the two half-rings 4.5 are simultaneously fitted onto the rotating column 3.2, a complete ring is formed. At this point, the two fixing holes 4.6.1 are aligned and secured together using the bolt assembly 4.6.2. (Reference) Figure 7 The complete ring can further restrict the sides of the guide plate 3.3 to a certain extent. The bolt kit 4.6.2 includes bolts and nuts, and this disclosure does not further limit the embodiments of any of the known bolts and nuts disclosed above.
[0053] Furthermore, in the third case, the two half-rings 4.5 lack limiting along the extending direction of the rotating column 3.2. Therefore, a limiting plate 4.5.1 for insertion into the sliding groove 3.2.1 is provided on the inner side of the half-ring 4.5, and the abutting column 4.1 abuts against the side of the limiting plate 4.5.1. (Reference) Figure 8When the abutting post 4.1 abuts against the limiting plate 4.5.1, the abutting force is also transmitted to the guide plate 3.3 through the half-ring 4.5, thus achieving the same limiting effect on its side. (Reference) Figure 12 The diagram shows two forms of the limiting plate 4.5.1. The limiting plate 4.5.1 not located at the end of the half-ring 4.5 has a thickness that is twice that of the limiting plate 4.5.1 located at the end of the half-ring 4.5. This arrangement ensures that when the two half-rings 4.5 are installed together, the two limiting plates 4.5.1 located at the ends of the half-rings 4.5 are joined together, and their thickness is exactly the same as that of the limiting plate 4.5.1 not located at the end of the half-ring 4.5.
[0054] In summary, the installation and usage methods of the finished product warehouse anti-segregation device are as follows:
[0055] Regarding the installation method of the limiting unit 4, in the first case, the guide plate 3.3 is inserted into the rotating column 3.2 along the sliding groove 3.2.1. The abutment column 4.1 is directly inserted into the sliding groove 3.2.1 and abuts against the bottom side of the guide plate 3.3. The fixing bolt 4.4 is screwed into the threaded groove 3.2.2 at the end of the rotating column through the mounting hole 4.3 on the mounting plate 4.2 to tighten it, clamping the abutment column and the guide plate.
[0056] In the second scenario, the guide plate is installed as described above. The two half-rings 4.5 are fitted onto the rotating column 3.2 from both sides to form a complete ring. The abutment column 4.1 rests against the side end of the guide plate 3.3. The fixing holes 4.6.1 on the aligned fixing plates 4.6 are tightened using the bolt kit 4.6.2. The mounting plate 4.2 is then secured with the fixing bolts 4.4. In this case, the half-rings provide a larger lateral constraint surface to limit the guide plate's wobbling.
[0057] In the third case, the guide plate is installed in the same way as above. The inner side of the half ring 4.5 is integrated with a protruding limiting plate 4.5.1. When the half ring is installed, the limiting plate 4.5.1 is inserted into the sliding groove 3.2.1 of the rotating column 3.2, and the abutting column 4.1 is changed to abut against the side of the limiting plate 4.5.1 inserted into the sliding groove.
[0058] Turn on the power unit driving conveyor belt 2, so that the mixed coarse and fine materials are conveyed to the inlet of finished product bin 1. Start the rotating power unit 3.1, ensuring that the rotation direction of the rotating power unit 3.1 is opposite to the discharge direction of conveyor belt 2, that is, the movement direction of the guide plate 3.3 is facing the discharge material flow. The coarse and fine materials thrown from the end of conveyor belt 2 fall into the working area of guide unit 3. Most of the fine materials will directly pass through the screen holes 3.3.1 on the rotating guide plate 3.3. The fine materials passing through the screen holes maintain their original parabolic trajectory and fall into the area of finished product bin 1 away from the end of conveyor belt 2. The coarse materials are intercepted by the plate surface of the rotating guide plate 3.3. These returned coarse materials eventually fall into the finished product bin 1 relatively close to the end of conveyor belt 2, overlapping or adjacent to the area of the naturally falling fine materials. In this way, the coarse materials that would have fallen further are forcibly pulled back to a position closer to the drop point, without affecting the thrown fine materials.
[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of the invention. Furthermore, the terms "vertical," "horizontal," "front," and "rear," etc., mentioned in the embodiments of the present invention indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. These are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be further noted that, unless otherwise explicitly specified and limited, terms such as "install," "connect," "join," and "fix" in the description should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
