[0044] Please refer to Figure 1-Figure 3, this embodiment provides a screening machine 100, the screening machine 100 includes a main body 110, a screening mesh group 120, a vibration mechanism 130, a discharging assembly 140 and a dust collecting assembly 150;
[0045] The main body 110 is equipped with a feed hopper 111 and a screening cavity 112; the screening mesh group 120 and the vibration mechanism 130 are arranged in the screening cavity 112, and the vibration mechanism 130 is used to drive the screening mesh group 120 to vibrate; the feed hopper 111 is used to transport the material to be screened to the screening mesh group 120; the discharge component 140 is connected to the main body 110, and is used to discharge the material sorted by the screening mesh group 120; the dust collection component 150 is used to extract dust in the screening cavity 112.
[0046] Please refer to Figure 1-Figure 3 , the working principle of the screening machine 100 is:
[0047] The screening machine 100 includes a main body 110, a screening mesh group 120, a vibration mechanism 130, a discharge assembly 140 and a dust collection assembly 150; the main body 110 is equipped with a feed hopper 111 and a screening cavity 112; the screening mesh group 120 and the vibration mechanism 130 are arranged in the screening cavity 112, and the vibration mechanism 130 is used to drive the screening mesh group 120 to vibrate; the feed hopper 111 is used to convey the material to be screened to the screening mesh group 120; the discharge assembly 140 is connected to the main body 110 and is used to discharge the material sorted by the screening mesh group 120; the dust collection assembly 150 is used to extract dust in the screening cavity 112.
[0048] Thus, during the operation of the screening machine 100, by pouring the material into the feed hopper 111, the material can be introduced into the screening mesh group 120 through the feed hopper 111, and screened by the screening mesh group 120, and the screened material will be discharged through the discharge assembly 140. In this process, since the screening process is carried out in the screening cavity 112, the screening cavity 112 can be relatively closed to prevent the dust separated during the screening process from entering the external environment and affecting the air quality of the environment. In addition, the air in the screening cavity 112 can be extracted by the dust collecting assembly 150, so that the separated dust can be collected and processed to prevent it from being mixed into the external air, which is beneficial to ensuring the air quality of the working environment.
[0049] In summary, the screening machine 100 has a simple structure and is easy to use. It can extract the air in the screening cavity 112 during the screening process, thereby preventing dust in the material from mixing into the air and affecting the air quality of the working environment.
[0050] For further information, please refer to Figure 1-Figure 4In this embodiment, the screening mesh assembly 120 includes a mounting frame 121 and at least one screening mesh panel 122 movably connected to the mounting frame 121. The mounting frame 121 is mounted in the screening cavity 112, and the screening mesh panel 122 is in transmission connection with a vibration mechanism 130. Thus, the vibration mechanism 130 can drive the screening mesh panel 122 on the mounting frame 121 to vibrate, thereby achieving a screening effect. Furthermore, since the vibration mechanism 130 is configured to drive the screening mesh panel 122 to vibrate through vibration, its specific structure can adopt the structure of the prior art.
[0051] Moreover, in this embodiment, the screening mesh group 120 includes two screening mesh plates 122, which are vertically spaced and parallel to each other; wherein the mesh diameter of the upper screening mesh plate 122 is larger than the mesh diameter of the lower screening mesh plate 122.
[0052] Thus, by configuring two screening meshes 122 with different mesh diameters, graded screening can be achieved. Furthermore, during the screening process, a single vibration mechanism 130 can be configured to drive both screening meshes 122 to vibrate. Alternatively, two vibration mechanisms 130 can be configured, each driving one screening mesh 122 to vibrate. Thus, during the screening process, the two vibration mechanisms 130 can be controlled to vibrate the two screening meshes 122 at the same frequency or at different frequencies. It should be noted that the vibration mechanism 130 utilizes existing technology, and therefore, its structure will not be described in detail herein.
[0053] The two screening plates 122 mentioned above are compatible with each other. Figure 1-Figure 4 The discharge assembly 140 includes at least two discharge hoppers 141, both of which are connected to the main body 110. Each discharge hopper 141 corresponds to a screening screen 122 and is used to discharge the material screened by the corresponding screening screen 122. This arrangement facilitates the classification and collection of the discharged material during the discharge process.
[0054] For further information, please refer to Figure 1-Figure 4As can be seen from the above, in this embodiment, the dust collection assembly 150 includes at least two exhaust pipes 151, and the two exhaust pipes 151 correspond to the two screening meshes 122, and each exhaust pipe 151 is arranged at the discharge end of the corresponding screening mesh 122. The purpose of this arrangement is to provide an exhaust pipe 151 at the discharge end of each screening mesh 122 based on the above arrangement of the two screening meshes 122, so as to extract the air at the processing end thereof, so that a negative pressure area is formed at the discharge end of each screening mesh 122, and the air flow moves from the feed end to the discharge end of the screening mesh 122, thereby facilitating the rapid collection of air mixed with dust and preventing it from flowing back to the outside through the feed hopper 111.
[0055] It should be noted that the structure of the dust collection assembly 150 is based on the fact that the screening cavity 112 is relatively closed, and this closed setting does not affect the feeding and discharging of materials. On this basis, in order to facilitate the observation of the progress of the screening, an opening 113 is provided above the main body 110 to open the screening cavity 112. The purpose is to facilitate the staff to observe the screening situation. On this basis, in order to prevent dust from spreading into the working environment through the opening 113, the dust collection assembly 150 also includes an air curtain nozzle 152. The air curtain nozzle 152 is connected to the main body 110 and is used to guide air from the feed end of the screening mesh 122 to the discharge end, thereby forming an air curtain at the opening 113. In other words, in this way, an air curtain can be formed to close the opening 113, so that dust can be prevented from spreading to the outside without affecting the staff's observation of the screening situation. Moreover, the air curtain is formed by blowing air from the feed end of the screening mesh 122 to the discharge end, so as not to affect the operation of the exhaust pipe 151.
[0056] For further information, please refer to Figures 1-9 In this embodiment, based on the above-mentioned structure with two screening panels 122, the mounting frame 121 can include two sub-frames 123, with each screening panel 122 being detachably connected to a corresponding sub-frame 123. This arrangement facilitates maintenance of the screening panel assembly 120 and allows staff to adjust the aperture combination of each screening panel 122 according to the material screening conditions.
[0057] Based on this, please refer to Figure 1-Figure 7 , each sub-frame 123 is provided with a mounting groove 124 along its extension direction, and both sides of the screening screen 122 are slidably engaged with the mounting groove 124; and a movable member 125 and a connecting member 126 are provided at one end of the sub-frame 123 facing the discharge assembly 140; the movable member 125 is rotatably connected to the sub-frame 123, and has a position of abutting or disengaging with the screening screen 122 located in the mounting groove 124;
[0058] The connecting member 126 is connected to the movable member 125 and is used to be threadedly connected to the sub-frame 123 or the screening screen 122 when the movable member 125 is located at a position abutting the screening screen 122 in the installation groove 124 to limit the movement of the movable member 125.
[0059] Therefore, in this way, the installation state of the connecting member 126 can be adjusted so that the movable member 125 can rotate relative to the sub-frame 123, and then when it rotates to a position where it does not abut against the screening screen 122, the screening screen 122 can be slid out of or into the sub-frame 123 along the installation groove 124 to facilitate its installation or disassembly; it should be noted that when using this method, when maintenance is required, the discharge assembly 140 at the discharge end needs to be removed to facilitate the installation or disassembly of the screening screen 122.
[0060] Please refer to Figures 1-9 In other embodiments of the present invention, as can be seen from the above, since the main body 110 is provided with an opening 113, one or more screening screens 122 can also be installed through the opening 113. To this end, the sub-frame 123 is provided with a plurality of positioning slots 127 and a plurality of positioning members 129. A plurality of positioning portions 128 are provided on both sides of the screening screen 122. Each positioning portion 128 is configured to engage with a corresponding positioning slot 127. Each positioning member 129 corresponds to a positioning portion 128. The positioning members 129 are configured to connect to the sub-frame 123 and abut against the corresponding positioning portion 128 to restrict movement of the positioning portion 128 in a direction away from the positioning slot 127. It should be noted that when such a detachable connection method is employed, the positioning members 129 can be threadedly connected to the positioning slot 127 and abut against the screening screen 122, or threadedly connected to the sub-frame 123 and provided with a corresponding structure that abuts against the screening screen 122.
[0061] Furthermore, in this embodiment, a discharge port 114 is provided below the main body 110 and communicates with the screening cavity 112. This arrangement is intended to facilitate the discharge of materials passing through the screening mesh assembly 120, as well as fine impurities in the materials.
[0062] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
