DETAILED DESCRIPTION

[0018] Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and so that the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0019] According to a first aspect of the embodiments of the present disclosure, a screening machine feeding device 100 is provided, comprising: a hopper assembly 110, which is formed with an inlet 1101, an outlet 1102 and a material passing channel 1103, the material passing channel 1103 being communicated between the inlet 1101 and the outlet 1102, and the inlet 1101 and the outlet 1102 being spaced apart along a first direction; a plurality of material blocking assemblies 120, which are arranged in the material passing channel 1103 and are located between the inlet 1101 and the outlet 1102 along the first direction; wherein the plurality of material blocking assemblies 120 are spaced apart along the first direction, and two adjacent material blocking assemblies 120 along the first direction are arranged in a staggered manner along a second direction, and the second direction intersects the first direction.

[0020] The screen feeding device 100 provided by the embodiment of the present disclosure comprises the funnel assembly 110 and a plurality of the material blocking assemblies 120. The funnel assembly 110 is formed with a material inlet 1101, a material outlet 1102 and a material passing channel 1103. In actual application, the material inlet 1101 can be arranged corresponding to the discharge end of the material conveying device, and the material outlet 1102 can be arranged corresponding to the screen plate of the screen machine, so as to facilitate the funnel to access the material and guide the material to flow to the screen plate through the material passing channel 1103, thereby realizing the feeding operation of the screen machine and facilitating the screen machine to screen the material. The material blocking assembly 120 is arranged in the material passing channel 1103. In actual application, the material blocking assembly 120 is used to receive the material, thereby changing the motion parameters of the material in the flowing process. For example, the material blocking assembly 120 can change the motion speed of the material by relatively contacting the material. In the first direction, the material blocking assembly 120 is located between the material inlet 1101 and the material outlet 1102, and a plurality of the material blocking assemblies 120 are distributed in the material passing channel 1103 in the form of interval arrangement. Meanwhile, in the second direction, a misalignment is formed between two adjacent material blocking assemblies 120 in the first direction, that is, a plurality of the material blocking assemblies 120 have a certain misalignment amount in the first direction and the second direction, so as to facilitate a plurality of the material blocking assemblies 120 to sequentially contact the material in the process that the material flows to the material outlet 1102 in the material passing channel 1103, thereby on the one hand, reducing the impact and wear of the material on the funnel assembly 110, reducing the maintenance cost of the funnel assembly 110 and prolonging the service life of the funnel assembly 110. On the other hand, the kinetic energy of the material is consumed in the process of impacting the material blocking assembly 120, and then a plurality of the material blocking assemblies 120 can buffer the material for multiple times, reduce the speed of the material flowing out of the material outlet 1102, reduce the impact of the material on the screen plate, and in the process of sequentially contacting the material, a plurality of the material blocking assemblies 120 are also beneficial to improving the dispersibility of the material flow, thereby avoiding the concentrated impact of the material on a certain area of the screen plate, reducing the wear of the screen plate, reducing the maintenance cost of the screen plate and prolonging the service life of the screen plate. Therefore, the screen feeding device 100 provided by the embodiment of the present disclosure can use a plurality of the material blocking assemblies 120 to buffer and disperse the material for multiple times, thereby reducing the impact and wear of the material on the screen plate, improving the maintenance frequency and cost of the screen machine, thereby saving the execution cost of the material screening operation and improving the execution efficiency of the material screening operation.

[0021] It should be noted that the screen feeding device 100 provided by the embodiment of the present disclosure can be used as a component of a material conveying device for feeding the screen machine, or as a component of a material screening system. The material conveying device can comprise a belt conveying device 200 or other conveying devices, and the material screening system can comprise the screen machine, which can be but is not limited to a banana screen, a straight-line screen or the like.

[0022] Taking the aforementioned material conveying equipment including a belt conveyor 200 as an example, such as Figure 1 As shown, the aforementioned inlet 1101 can be used to insert the conveyor belt of the belt conveyor 200 so that the discharge end roller 210 of the belt conveyor 200 passes through the inlet 1101 and is arranged in the material passage 1103, thereby facilitating the material on the conveyor belt to enter the material passage 1103 through the inlet 1101. In practical applications, the funnel assembly 110 can be installed according to the relative positional relationship between the aforementioned discharge end roller 210 and the screen plate of the screen machine, so that the funnel assembly 110 can guide the material to the screen plate. For example, when the discharge end roller 210 and the screen plate are arranged along the direction of gravity, the aforementioned first direction can be consistent with or approximately the same as the direction of gravity. Correspondingly, the aforementioned second direction can be a horizontal direction or a direction with a high degree of horizontality, so that the flow rate of the material changes during the process of sequentially contacting multiple baffle assemblies 120, thereby improving the buffering effect of the baffle assembly 120 on the material.

[0023] It is understood that the aforementioned baffle assembly 120 can be disposed on the inner wall of the funnel assembly 110 to maintain stability under the support of the funnel assembly 110, thereby reducing the risk of the baffle assembly 120 changing position or falling off under the impact of materials. In practical applications, the specific placement of multiple baffle assemblies 120 on the funnel assembly 110 can be determined based on the test results of the material flow path, in order to increase the probability of contact between the baffle assembly 120 and the material and enhance the buffering effect of the baffle assembly 120 on the material. In determining the specific placement positions of multiple baffle components 120 on the funnel assembly 110 based on the test results of the material flow path, the installation position of the baffle component 120 closest to the inlet 1101 in the first direction can be determined first. For example, the funnel assembly 110 without baffle components 120 can be assembled with the belt conveyor 200, and the flow path of the material in the funnel assembly 110 can be determined. Based on the aforementioned flow path, the installation position of the baffle component 120 closest to the inlet 1101 can be determined so that the baffle component 120 is located on the aforementioned flow path. After the installation position of the baffle component 120 closest to the inlet 1101 is determined, the baffle component 120 closest to the inlet 1101 can be installed in the corresponding position, and the material flow path can be further tested. Similarly, the installation position of the second baffle component 120 closest to the inlet 1101 in the first direction can be determined. And so on, to achieve the determination of the installation positions of multiple baffle components 120 one by one. There are multiple ways to determine the specific placement of the aforementioned multiple material blocking components 120 on the funnel component 110, and it is not limited to the method provided in the aforementioned example.

[0024] It should be noted that in practical applications, the relative position between the discharge port 1102 and the screen can be optimized according to the flow path of the material flowing out of the discharge port 1102, so that the screen feeding device 100 reverses the material flow of the screen to the screen distribution, so that the material is more evenly distributed on the screen plate and further improves the screening efficiency of the material.

[0025] It is understood that the aforementioned materials may be, but are not limited to, bulk materials, such as ores, coal, sand, grains, etc.

[0026] In some examples, the plurality of baffle assemblies 120 include: a first baffle assembly 121; and a second baffle assembly 122, located between the first baffle assembly 121 and the discharge port 1102 along a first direction; wherein at least a portion of the first baffle assembly 121 is made of an impact-resistant material.

[0027] In this technical solution, the multiple material blocking components 120 can be divided into the aforementioned first material blocking component 121 and the aforementioned second material blocking component 122. Based on the aforementioned configuration, in the first direction, the first material blocking component 121 is closer to the feed inlet 1101 than the second material blocking component 122. Furthermore, the first material blocking component 121 can be made of impact-resistant material, thereby improving the structural strength of the first material blocking component 121, enhancing its ability to resist impact and wear, and extending its service life.

[0028] It is understandable that in practical applications, the first baffle assembly 121 is more likely to come into contact with the material and be impacted by the material than the second baffle assembly 122. As a result, the impact on the first baffle assembly 121 will be relatively greater. Based on the aforementioned settings of this technical solution, the reliability of the first baffle assembly 121 can be improved.

[0029] It is understood that there can be multiple first stop components 121 and / or second stop components 122. When there are multiple first stop components 121, the multiple first stop components 121 are arranged at intervals along a first direction, and two adjacent first stop components 121 along the first direction are staggered in a second direction; adjacent first stop components 121 and second stop components 122 along the first direction are also staggered in a second direction. When there are multiple second stop components 122, the multiple second stop components 122 are arranged at intervals along the first direction, and two adjacent second stop components 122 along the first direction are staggered in a second direction; adjacent first stop components 121 and second stop components 122 along the first direction are also staggered in a second direction.

[0030] Understandably, at least part of the second baffle assembly 122 may also be made of an impact-resistant material.

[0031] It can be understood that the aforementioned impact-resistant material can be but is not limited to a metal material.

[0032] In some examples, the second material blocking assembly 122 is formed with a receiving groove 122a close to one side of the material inlet 1101.

[0033] In this technical solution, the second material blocking assembly 122 can be formed with a receiving groove 122a close to one side of the material inlet 1101; based on the foregoing arrangement, when the second material blocking assembly 122 comes into contact with the material, at least part of the material can be accommodated by the receiving groove 122a, accordingly, as the amount of material accumulated in the receiving groove 122a increases, the material can overflow from the second material blocking assembly 122 in an overflowing manner to further flow to the material outlet 1102, thereby being able to improve the buffering effect of the material and facilitating the dispersion of the material in the receiving groove 122a, expanding the material flow distribution range after the material leaves the second material blocking assembly 122, further avoiding the concentrated impact of the material on the local area of the screen plate, and facilitating the wide distribution of the material on the screen plate, improving the screening efficiency of the material.

[0034] In some examples, the length direction of the receiving groove 122a extends along a third direction, the third direction being different from the first direction and the second direction, and the number of the second material blocking assemblies 122 is at least two, wherein the length of the receiving groove 122a of any one of the second material blocking assemblies 122 close to the material inlet 1101 along the first direction is greater than the length of the receiving groove 122a of the other second material blocking assembly 122 away from the material inlet 1101 along the first direction.

[0035] In this technical solution, the length relationship of the receiving grooves 122a of the plurality of second material blocking assemblies 122 is limited; based on the foregoing arrangement, the length of the receiving groove 122a close to the material outlet 1102 in the first direction can be made larger, thereby facilitating the gradual dispersion of the material during the flow process and flowing out of the material outlet 1102 in the form of a larger distribution range, facilitating the dispersion of the material in the receiving groove 122a, expanding the material flow distribution range after the material leaves the second material blocking assembly 122, further avoiding the concentrated impact of the material on the local area of the screen plate, and facilitating the wide distribution of the material on the screen plate, improving the screening efficiency of the material.

[0036] It can be understood that the aforementioned first direction, second direction, and third direction can be two perpendicular directions, wherein the first direction can be arranged along the direction of gravity, the second direction and the second direction are two horizontal directions, accordingly, the first direction and the second direction can be the depth direction and the width direction of the receiving groove 122a; in actual application, the third direction can match the width direction of the screen plate, so as to facilitate the uniform distribution of the material in the width direction of the screen plate, improving the screening efficiency and effect of the material.

[0037] It can be understood that the length of the discharge port 1102 in the third direction is greater than or equal to the length of the receiving groove 122a, so as to avoid the material from being concentrated again when flowing through the discharge port 1102.

[0038] In some examples, the first material blocking assembly 121 comprises: a first support 1211 arranged in the hopper assembly 110 and located in the material passing channel 1103; and a first material blocking piece 1212 arranged in the first support 1211 and located on the side of the first support 1211 close to the material inlet 1101; wherein, along the first direction, the first material blocking assembly 121 is located between the material inlet 1101 and the discharge port 1102.

[0039] In this technical solution, the first material blocking assembly 121 can comprise the first support 1211 and the first material blocking piece 1212; based on the foregoing arrangement, the first material blocking assembly 121 can use the first material blocking piece 1212 to receive and buffer the material, and use the first support 1211 to connect the first material blocking piece 1212 and the hopper assembly 110, thereby improving the stability and reliability of the first material blocking piece 1212 and reducing the risk of position change or falling of the first material blocking piece 1212.

[0040] It can be understood that the first material blocking piece 1212 and / or the first support 1211 can be made of an impact-resistant material.

[0041] In some examples, the second material blocking assembly 122 comprises: a second support 1221 arranged in the hopper assembly 110 and located in the material passing channel 1103; and a second material blocking piece 1222 arranged in the second support 1221 and located on the side of the second support 1221 close to the material inlet 1101; wherein, along the first direction, the second material blocking piece 1222 is located between the first material blocking piece 1212 and the discharge port 1102.

[0042] In this technical solution, the second material blocking assembly 122 can comprise the second support 1221 and the second material blocking piece 1222; based on the foregoing arrangement, the second material blocking assembly 122 can use the second material blocking piece 1222 to receive and buffer the material, and use the second support 1221 to connect the second material blocking piece 1222 and the hopper assembly 110, thereby improving the stability and reliability of the second material blocking piece 1222 and reducing the risk of position change or falling of the second material blocking piece 1222.

[0043] It can be understood that the second material blocking piece 1222 and / or the second support 1221 can be made of an impact-resistant material.
