Description

Technical Field

[0001] This utility model belongs to the field of material screening and crushing technology, and particularly relates to an integrated material guiding device and a pre-screening and crushing system. Background Technology

[0002] Mobile impact crushers integrate crushing and screening systems, equipped with vehicle-mounted chassis or tracked walking mechanisms, and are mainly used in mobile crushing scenarios such as mining, construction waste treatment, and transportation engineering. Because mobile crushing plants can perform on-site crushing of materials, eliminating the intermediate step of transporting materials away from the site for further crushing, logistics and transfer are more direct and efficient, maximizing cost reduction.

[0003] Currently, mobile impact crushers typically have a pre-screening device before the crushing unit to screen out materials finer than the crushing unit's output, allowing them to directly proceed to the next step. This pre-screening reduces the load on the crushing unit and lowers energy consumption. However, the pre-screening device consists of an upper primary screening component guiding the crushing unit and a lower screening component guiding the receiving conveyor to the next step. To ensure a tight seal and efficient feeding, both the crushing unit and the receiving conveyor require their own housings to connect with the pre-screening device, and each housing has its own guiding structure. This results in complex structures for both the crushing unit and the receiving conveyor, making maintenance difficult. Utility Model Content

[0013] In one embodiment of the present invention, the crushing docking part is configured to be inclined toward the pre-screening device in the direction from top to bottom. The integrated material guiding device also includes a second material blocking module corresponding to the feed inlet on the material guiding housing. The first material blocking module and the second material blocking module are arranged sequentially at intervals in the direction from the pre-screening device toward the crushing device. The first material blocking module is suspended in the inner cavity of the material guiding housing, and the second material blocking module is suspended and extends into the inner cavity of the crushing device.

[0014] In one embodiment of this utility model, the first material blocking module is configured as a material blocking plate module, and the second material blocking module is configured as a material blocking chain module.

[0015] In one embodiment of this utility model, the upper end of the material guide housing is provided with a plurality of mounting ports spaced apart, and the plurality of mounting ports are used for the insertion, removal and disassembly of a plurality of material blocking components in the first material blocking module.

[0016] In one embodiment of this utility model, the lower end of the first pair of interfaces is provided through the lower end of the material guide housing, and a lower baffle module is detachably connected to the material guide housing.

[0018] In one embodiment of this utility model, the material guide housing is detachably installed with lateral flexible dustproof plates on both the left and right sides of the first pair of interfaces. The lateral flexible dustproof plates are located on the upper side of the lower baffle module and are used to extend out on both the upper and lower sides of the secondary screening component.

[0019] To achieve the above objectives, the second aspect of this utility model provides a pre-screening and crushing system, wherein the pre-screening and crushing system includes a feeding hopper device, a pre-screening device, a crushing device, a receiving and conveying device, and an integrated material guiding device as described above.

One end of the docking hopper is connected to the third pair of interfaces of the guiding shell, and the other end extends to the receiving and conveying device. Simultaneously, the first pair of interfaces of the guiding shell allows the primary screening element in the pre-screening device to pass through and extend to the feed inlet of the crushing device, and allows the secondary screening element in the pre-screening device to extend in, thereby ensuring that the material on the primary screening element passes through the guiding shell... After passing through the cavity of the material shell, the material enters the crushing device. The material on the secondary screening component can flow to the receiving conveyor after being guided by the material guide shell and the docking hopper. This eliminates the need for the crushing device and the receiving conveyor to have their own separate shells to dock with the pre-screening device. In addition, the first blocking module for blocking the material entering the crushing device is integrated into the material guide shell, so it does not need to be set on the crushing device. This reduces the complexity of the structure of the crushing device and the receiving conveyor. After the integrated material guide device is disassembled, it can be easily maintained.

[0023] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0025] Explanation of reference numerals in the attached figures: Detailed Implementation

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] The integrated feeding device and pre-screening and crushing system of this utility model are described below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides an integrated material guiding device 100, wherein the integrated material guiding device 100 includes: The material guide housing 110 is used to be installed between the pre-screening device 300 and the crushing device 400. The material guide housing 110 is provided with a first pair of interfaces 111 and a second pair of interfaces 1121 on opposite sides, and a third pair of interfaces at the lower end. The second pair of interfaces 1121 is sealed and connected to the feed inlet of the crushing device 400. The first pair of interfaces 111 is used for the primary screening component 310 in the pre-screening device 300 to pass through and extend to the feed inlet, and for the secondary screening component 320 in the pre-screening device 300 to extend in. The docking hopper 120 is connected to the lower end of the material guide housing 110, and one end of the docking hopper 120 communicates with the third pair of interfaces, and the other end extends to the receiving and conveying device 500. The first material blocking module 130 has a corresponding inlet located on the material guide housing 110.

[0029] When using the aforementioned integrated material guiding device 100, since the integrated material guiding device 100 can be installed on the pre-screening device 300 and the crushing device 400 and includes a material guiding shell 110, a docking hopper 120 and a first baffle module 130, the second pair of interfaces 1121 of the material guiding shell 110 is sealed and connected to the feed inlet of the crushing device 400, one end of the docking hopper 120 is connected to the third pair of interfaces of the material guiding shell 110, and the other end extends to the receiving and conveying device 500. At the same time, the first pair of interfaces 111 of the material guiding shell 110 allows the primary screening component 310 in the pre-screening device 300 to pass through and extend to the feed inlet of the crushing device 400, and allows the secondary screening component 320 in the pre-screening device 300 to extend in, thereby allowing the primary screening component 310 to... After passing through the cavity of the guide housing 110, the material enters the crushing device 400. The material on the secondary screening component 320 can flow to the receiving conveyor 500 after being guided by the guide housing 110 and the docking hopper 120. This eliminates the need for the crushing device 400 and the receiving conveyor 500 to have their own separate housings for docking with the pre-screening device 300. In addition, the first blocking module 130 for blocking the material entering the crushing device 400 is integrated into the guide housing 110, so it does not need to be set on the crushing device 400. This reduces the complexity of the structure of the crushing device 400 and the receiving conveyor 500. After the integrated guide device 100 is disassembled, it can be easily maintained.

[0030] Specifically, the primary screening element 310 is located above the secondary screening element 320. Material in the pre-screening device 300 first flows through the primary screening element 310. The primary screening element 310 can be a screen plate with a first screen hole, and is inclined downwards in the direction from feed to discharge. Material with a particle size smaller than the first screen hole flows down to the secondary screening element 320, while material with a particle size larger than the first screen hole enters the crushing device 40 along the primary screening element 310 from the first interface 111. 0. The secondary screening component 320 can be a screen with a second screen hole, and is inclined downwards in the direction of feeding towards discharging. The diameter of the second screen hole is smaller than that of the first screen hole. Material with a particle size smaller than the second screen hole flows onto the bottom wall 330 of the pre-screening device 300 on the lower side. Material with a particle size larger than the second screen hole enters the guide housing 110 from the first interface 111 along the secondary screening component 320, and flows through the docking hopper 120 and falls onto the receiving conveying device 500. In addition, the docking hopper 120 can be integrally connected to the guide housing 110, or welded to the guide housing 110, or the docking hopper 120 can be detachably installed on the guide housing 110. The detachably installed docking hopper 120 can be a flexible component, such as a rubber component, or a rigid component, such as a metal component.

[0031] See Figures 2 to 5In one embodiment of this utility model, the feed guide housing 110 includes a crushing docking part 112 and a reserved maintenance part 113 arranged sequentially from top to bottom. The crushing docking part 112 is provided with a second pair of interfaces 1121. The reserved maintenance part 113 is arranged at an interval from the crushing device 400, and the reserved maintenance part 113 is provided with a maintenance port 1131 on the side facing the crushing device 400. The reserved maintenance part 113 is detachably connected to a maintenance plate module 150 that closes the maintenance port 1131. Since the reserved maintenance part 113 is located at the lower part of the feed guide housing 110, and the secondary screening component 320 is also arranged at the lower part of the feed guide housing 110, when the secondary screening component 320 needs to be maintained, the maintenance plate module 150 can be removed and maintenance can be carried out through the maintenance port 1131. This obviously solves the problem of the secondary screening component 320 being difficult to maintain in the prior art.

[0032] In one embodiment of this utility model, the side of the reserved maintenance section 113 facing the crushing device 400 is inclined towards the pre-screening device 300 from bottom to top. This arrangement allows for a larger gap between the secondary screening component 320 and the crushing device 400 on its upper side, and also causes the inner cavity of the guide housing 110 corresponding to the reserved maintenance section 113 to gradually increase from top to bottom, facilitating the flow of material from the secondary screening component 320 into the guide housing 110. Of course, this utility model is not limited to this; it can be implemented as long as the side of the reserved maintenance section 113 facing the crushing device 400 is spaced apart from the crushing device 400 to create a gap.

[0033] like Figure 4 and Figure 5 As shown, in one embodiment of this utility model, the inspection plate module 150 includes a flexible cover plate 151 and a metal cover plate 152. The flexible cover plate 151 and the metal cover plate 152 are arranged sequentially from top to bottom in the inspection port 1131. The flexible cover plate 151 is placed on the upper side of the secondary screening component 320, and the metal cover plate 152 is arranged opposite to the secondary screening component 320. That is, the inspection plate module 150 can be divided into two types: the flexible cover plate 151 and the metal cover plate 152. The flexible cover plate 151 is set on the upper side of the secondary screening component 320, which can slow down the speed of some thrown materials and seal the dust points on the upper side of the inspection port 1131. The metal cover plate 152 is set in a position opposite to the secondary screening component 320 to play a wear-resistant role. Specifically, the flexible cover plate 151 includes, but is not limited to, rubber parts, and the metal cover plate 152 includes, but is not limited to, metal wear-resistant parts. The number of metal cover plates 152 can be set to at least two, and at least two metal cover plates 152 are arranged sequentially from top to bottom on the lower side of the flexible cover plate 151, preferably two.

[0034] In one embodiment of this utility model, the crushing docking part 112 extends outward from the four periphery of the second pair of interfaces 1121 and is provided with a docking frame 1122. The docking frame 1122 is designed to fit snugly against the periphery of the feed inlet. The addition of the docking frame 1122 facilitates docking with the feed inlet of the crushing device 400. Specifically, a sealing gasket can be sandwiched between the docking frame 1122 and the periphery of the feed inlet, and then the docking frame 1122 can be disassembled and connected to the periphery of the feed inlet using threaded fasteners. The portion of the docking frame 1122 corresponding to the lower edge of the second pair of interfaces 1121 is designated as the lower side plate 1123 of the frame. The upper end of the flexible cover plate 151 extends into the inner side of the lower side plate 1123 of the frame and is disassembled and connected to the lower side plate 1123 of the frame. Thus, the docking frame 1122, which is used to dock with the periphery of the feed inlet, can be cleverly designed as the mounting part of the flexible cover plate 151. In addition, the flexible cover plate 151 seals the dust points at the lower end of the lower side plate 1123 of the frame on the inner side, which is significantly better than the outer side sealing. The lower side plate 1123 of the frame covers the upper end of the flexible cover plate 151 on the outer side, which can also improve the aesthetics.

[0035] In one embodiment of this utility model, the lower end of the flexible cover plate 151 is spliced ​​with the upper end of the metal cover plate 152, and the inspection plate module 150 also includes a first pressure strip 153. The flexible cover plate 151 and the first pressure strip 153 are stacked sequentially on the outside of the inspection port 1131, that is, the flexible cover plate 151 is located between the outside of the guide housing 110 and the first pressure strip 153. The first pressure strip 153 includes two vertical segments 1531 and a horizontal segment 1532 connecting the lower ends of the two vertical segments 1531. The two vertical segments 1531 respectively disassemble and press the left and right ends of the flexible cover plate 151 onto the left and right sides of the inspection port 1131. By adding the first pressure strip 153, on the one hand, the two vertical strips 1531 can be detachably connected to the guide housing 110 at the left and right ends of the flexible cover plate 151 respectively, and on the other hand, the horizontal strip 1532 can press against the lower end of the flexible cover plate 151 on the outside to ensure the fit between the lower end of the flexible cover plate 151 and the upper end of the metal cover plate 152.

[0036] Specifically, the first pressure strip 153 can be removed from the outside, and the flexible cover plate 151 can be lifted upwards to facilitate safe observation of the operation of the secondary screening component 320 during equipment operation. It can also be used to inspect whether the secondary screening component 320 is blocked or broken when the machine is stopped. The metal cover plate 152 has ear plates extending from both the left and right sides, which can be pulled out from the outside for replacement when the wear is severe.

[0037] In one embodiment of the present invention, a support beam 154 is also detachably installed on the inner side of the material guide housing 110. The support beam 154 is correspondingly arranged with the flexible cover plate 151. The support beam 154 can stop the flexible cover plate 151 from the inner side of the material guide housing 110, and can also strengthen the material guide housing 110.

[0038] See Figure 5 In one embodiment of this utility model, the reserved maintenance section 113 is provided with a maintenance extraction section 1132 and a lower stop section 1133 in a top-to-bottom direction. The maintenance extraction section 1132 is provided with a first flange plate 1134 that is bent outward on the left and right sides corresponding to the maintenance opening 1131. The lower stop section 1133 is provided with an upward-facing mounting surface 1135 on the lower side of the first flange plate 1134. The left and right ends of the maintenance plate module 150 are respectively detachably connected to the corresponding first flange plate 1134, and the lower end of the maintenance plate module 150 is placed on the mounting surface 1135. Thus, through the arrangement of the first flanges 1134 on both sides of the inspection port 1131 and the mounting surface 1135 on the lower side of the first flanges 1134, a lateral pull-out space is formed on the guide housing 110. The inspection plate module 150 can be pulled out and disassembled within this pull-out space, which is particularly suitable for scenarios where the front installation space is severely insufficient, thereby facilitating the disassembly and assembly of long and heavy inspection plate modules 150. Specifically, the lower end of the metal cover plate 152 located at the bottom of the inspection plate module 150 can be placed on the mounting surface 1135 for pulling out, while the upper metal cover plate 152 can be pulled out and moved on the next metal cover plate 152.

[0039] In one embodiment of this utility model, the lower end of the inspection port 1131 extends through the lower end of the material guide housing 110. That is, in addition to the inspection and extraction section 1132, the lower stop section 1133 of the reserved inspection section 113 is also configured to enclose the inspection port 1131 on both the left and right sides. Furthermore, the portions of the lower stop section 1133 that correspondingly enclose the inspection port 1131 on both the left and right sides are all bent inwards with second flange plates 1136. The second flange plates 1136 and... The first flange plate 1134 is staggered and located on the side of the first flange plate 1134 facing the crushing device 400. The upper end of the second flange plate 1136 is set as a mounting surface 1135. The mounting surface 1135 formed by the second flange plate 1136 can increase the size of the mounting surface 1135. The lower stop section 1133 is detachably connected to the lower baffle 1137 of the lower area of ​​the closed maintenance port 1131 on the inner side of the second flange plate 1136. That is, in addition to the maintenance plate module 150, the reserved maintenance section 113 also has a lower baffle 1137 located below the maintenance plate module 150. The lower baffle 1137 is also detachable, which can facilitate production, replacement and maintenance.

[0040] Please see again Figures 2 to 5 In one embodiment of the present invention, the crushing docking part 112 is configured to be inclined towards the pre-screening device 300 in the direction from top to bottom, so as to match the periphery of the feed inlet of the crushing device 400. The integrated material guiding device 100 also includes a second baffle module 140 corresponding to the feed inlet and disposed on the material guiding housing 110. The first baffle module 130 and the second baffle module 140 are arranged sequentially at intervals in the direction from the pre-screening device 300 towards the crushing device 400. The first baffle module 130 is suspended in the inner cavity of the material guiding housing 110, and the second baffle module 140 is suspended and extends into the inner cavity of the crushing device 400. That is, there are two material-blocking modules on the material guide housing 110. The first material-blocking module 130, which is completely placed inside the inner cavity of the material guide housing 110, can first stop the material. The second material-blocking module 140, which extends into the inner cavity of the crushing device 400, can then stop the material. In this way, while gradually slowing down the speed of the material entering the crushing device 400, the space occupied by the entire integrated material guide device 100 is also reduced. Specifically, the first material-blocking module 130 is a baffle plate module, and the second material-blocking module 140 is a baffle chain module. Of course, this utility model is not limited to this, and the two material-blocking modules can also be of the same type.

[0041] In one embodiment of this utility model, the upper end of the guide housing 110 is provided with a plurality of mounting ports 114 spaced apart, which are used for the insertion, removal, and disassembly of a plurality of material blocking components in the first material blocking module 130. The addition of mounting ports 114 facilitates the installation and removal of the material blocking components in the first material blocking module 130. Specifically, when the first material blocking module 130 is configured as a material blocking plate module, the material blocking plate module includes a plurality of material blocking plates. Each material blocking plate includes a plate body and two angle steel bodies. The two angle steel bodies are located at the upper end of the plate body and are respectively disposed on opposite sides of the plate body. The plate body can be inserted into or removed from the mounting ports 114. When the plate body is inserted into the inner cavity of the guide housing 110, the two angle steel bodies abut against the top wall of the guide housing 110.

[0042] See Figure 2 and Figure 3In one embodiment of this utility model, the lower end of the first pair of interfaces 111 extends through the lower end of the guide housing 110, and a lower baffle module 160 is detachably connected to the guide housing 110. The lower baffle module 160 closes the lower area of ​​the first pair of interfaces 111, and the upper area of ​​the first pair of interfaces 111 is used for the primary screening component 310 and the secondary screening component 320 to extend into. That is, the side of the guide housing 110 facing the pre-screening device 300 is provided as the detachable and installable lower baffle module 160, so as to facilitate production, replacement and maintenance. Of course, this utility model is not limited to this, and it is also possible for the side of the guide housing 110 facing the pre-screening device 300 to be integrally formed with the guide housing 110.

[0043] In one embodiment of this utility model, the lower baffle module 160 includes a lower flexible dustproof plate 161 and a metal baffle 162. The metal baffle 162 is detachably connected to the material guide housing 110. The lower end of the lower flexible dustproof plate 161 is fitted to the upper end of the metal baffle 162, and is detachably pressed onto the left and right sides of the first pair of interfaces 111 by a second pressure strip 163. The lower flexible dustproof plate 161 is used to press against the portion of the pre-screening device 300 that extends into the material guide housing 110. By adding the lower flexible dustproof plate 161 to the lower baffle module 160, the dust emission point at the upper end of the metal baffle 162 can be sealed, and the pressing effect of the portion extending into the pre-screening device 300 can also be improved. Specifically, the lower flexible dustproof plate 161 may be, but is not limited to, a rubber part, and the part of the pre-screening device 300 that extends into the material guide housing 110 and presses against the lower flexible dustproof plate 161 may be a secondary screening part 320 or a plate forming the bottom wall 330 in the pre-screening device 300.

[0044] In one embodiment of this utility model, the material guide housing 110 is detachably installed with lateral flexible dustproof plates 164 on both the left and right sides of the first pair of interfaces 111. The lateral flexible dustproof plates 164 are located on the upper side of the lower baffle module 160 and are used to extend out on both the upper and lower sides of the secondary screening component 320. That is, by adding the lateral flexible dustproof plates 164, the dust-generating points of the first pair of interfaces 111 located above and below the secondary screening component 320 can be sealed on both the left and right sides.

[0045] Specifically, in the past, the undersize hopper of the pre-screening device 300 and the feed hopper of the crushing device 400 were designed independently, which occupied more space in the overall layout design of the mobile crushing station, making it difficult to maintain the main equipment and replace the corresponding vulnerable parts. The integrated material guiding device 100 provided by this utility model provides design space for the pre-screening device 300, which can increase the length compared to the previous design, thereby increasing the screening area and providing better screening performance for wet materials. At the same time, the pre-screening device 300 has two screening layers. The first screening layer is used for preliminary screening, and the second screening layer is used for further fine screening. This produces three types of materials. The first type of large material enters the crushing device 400. The second type of small material bypasses the crushing device 400 and enters the finished product screening to become the final sand and gravel aggregate product. The third type of small material can be discharged. It can be transported out as waste material through the undersize conveyor 350, or after blocking the discharge port 340, it enters the finished product screening together with the second type of small material to become the finished product.

[0046] In addition, see Figure 1 This utility model also provides a pre-screening and crushing system, which includes a feeding hopper device 200, a pre-screening device 300, a crushing device 400, a receiving and conveying device 500, and an integrated material guiding device 100 as described above. The feeding hopper device 200 is equipped with a vibrating feeder 201, and its outlet is located above the primary screening component 310. The pre-screening device 300 is equipped with a vibrating screener 301, and its bottom wall 330 is inclined and has a discharge port 340. A screen under-screen conveying device 350 is located below the discharge port 340. Since the pre-screening and crushing system adopts all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0047] Specifically, the feeding hopper device 200 and the pre-screening device 300 are respectively equipped with a vibrating feeder 201 and a vibrating screener 301, allowing for independent control using their respective vibrating motors and a clear division of labor. Furthermore, the material undersize by the secondary screening element 320 in the pre-screening device 300 flows to the bottom wall 330 and, guided by the bottom wall 330, flows into the discharge port 340, ultimately flowing to the undersize conveying device 350. This is particularly suitable for scenarios requiring the removal of impurities from materials.

[0048] In one embodiment of this utility model, the pre-screening device 300 has a bottom wall 330 plate extending into the guide housing 110 from the first pair of interfaces 111, and a sealing plate is detachably installed on the bottom wall 330 to seal the discharge port 340. That is, when the material screened by the secondary screening component 320 is not impurities, the discharge port 340 can be sealed by the sealing plate, so that the material screened by the secondary screening component 320 can be guided through the bottom wall 330 to the inner cavity of the guide housing 110, and enter the docking hopper 120 together with the material flowing in from the secondary screening component 320 and flow to the receiving and conveying device 500, thereby expanding different application scenarios.

[0049] Furthermore, this utility model also provides a mobile machine, which includes the pre-screening and crushing system described above. Since the mobile machine adopts all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.
