The geometric center of the mounting rack 141 is provided with a first bevel gear 142, which is connected with the output end of the driving motor 132. The upper and lower sides of the first bevel gear 142 are provided with a second bevel gear 143 and a third bevel gear 144. The second bevel gear 143 is provided with a transmission rod 145 inside. The lower side of the transmission rod 145 is connected with the first lower rotating wheel 162. The third bevel gear 144 is connected with the first upper rotating wheel 161. Specifically, the driving motor 132 provides driving power acting on the first bevel gear 142. The rotation of the first bevel gear 142 is meshed with the second bevel gear 143 and the third bevel gear 144, respectively. During this process, the rotation of the second bevel gear 143 will rotate together with the transmission rod 145, and the driving power will act on the first lower rotating wheel 162. At this time, the first lower rotating wheel 162 rotates counterclockwise, which can pull the first driving belt 139 on the first fixed pulley 133. At the same time, because the first lower rotating wheel 162 rotates counterclockwise, the corresponding first upper rotating wheel 161 rotates clockwise and pulls the first driving belt 139 on the second fixed pulley 134. At this time, the first driving belt 139 on both sides is wound on the first forward and reverse rotating wheel 16, completing the pulling of the stirring assembly 12. During this process, the second coaxial reverse rotation assembly 15 is a feeding process for the second driving belt 1310, that is, the second driving belt 1310 wound on the second forward and reverse rotating wheel 17 is fed. Specifically, the second coaxial reverse rotation assembly 15 comprises a stable rack 151 designed in an L shape. The two sides of the end of the stable rack 151 are provided with a matching bevel gear 152. The matching bevel gear 152 is rotatably connected with the two ends of the stable rack 151, and the two are mirror image arranged, which promotes the reverse rotation of the fourth bevel gear 153 and the fifth bevel gear 154. The upper and lower sides of the matching bevel gear 152 are provided with the fourth bevel gear 153 and the fifth bevel gear 154, which are respectively meshed with the matching bevel gear 152, ensuring the effective transmission of driving power and the smooth operation of the device. The upper side of the second bevel gear 143 is connected with the fifth bevel gear 154, and the connection is rotatable relative to the upper side of the mounting rack 141. The transmission rod 145 penetrates the fourth bevel gear 153 and is connected with the second upper rotating wheel 171. The fourth bevel gear 153 is connected with the second lower rotating wheel 172, and the connection between the fourth bevel gear 153 and the second lower rotating wheel 172 is rotatable relative to the upper side of the stable rack 151, ensuring the stability of the device components. It needs to be further explained that one end of the second driving belt 1310 is fixed on the second lower rotating wheel 172 of the second forward and reverse rotating wheel 17.And the third fixed pulley 135 and the fifth fixed pulley 137 are connected with the second connecting buckle 128, the other second drive belt 1310 is fixed on the second upper rotating wheel 171 of the second forward and reverse rotating wheel 17, and is connected with the second connecting buckle 128 through the fourth fixed pulley 136 and the sixth fixed pulley 138. The specific description is as follows: when the first lower rotating wheel 162 rotates counterclockwise, the transmission rod 145 rotates counterclockwise, the driving force acts on the fifth bevel gear 154 through the second bevel gear 143, the counterclockwise rotation of the fifth bevel gear 154 is meshed with the matching bevel gear 152 to act on the fourth bevel gear 153, so that the fourth bevel gear 153 rotates clockwise and acts on the second lower rotating wheel 172 of the second forward and reverse rotating wheel 17. At this time, the second lower rotating wheel 172 rotates clockwise, and since the material pushing assembly 12 is moved towards the driving assembly 13 first, the rotation of the second lower rotating wheel 172 will make the second drive belt 1310 wound thereon in a state of being unwound, that is, pulled out of the second lower rotating wheel 172 by the material pushing assembly 12. Similarly, the transmission rod 145 is connected with the second upper rotating wheel 171 by penetrating the fourth bevel gear 153, and when the second upper rotating wheel 171 rotates counterclockwise, the second drive belt 1310 wound thereon is in a state of being unwound through the fourth fixed pulley 136 and the sixth fixed pulley 138. The above operation mode realizes the movement of the material pushing assembly 12 from the material covering cover 11 to the other side of the shell 9, and also realizes the movement of the material discharged from the screening group 10, so that the screening work is completed. That is, when the material pushing assembly 12 moves from right to left, the first drive belt 139 is in a state of being wound, and the second drive belt 1310 is in a state of being unwound. Of course, the reverse operation of the material pushing assembly 12 also needs to be considered. At this time, only the reverse rotation of the driving motor 132 is needed. In this way, the first drive belt 139 is in a state of being unwound under the drive of the first coaxial reverse rotating assembly 14, and the second drive belt 1310 is in a state of being wound. For the first drive belt 139 and the second drive belt 1310, they can be high-strength belts or workpieces made of the same material as the synchronous belt in the prior art. Of course, the selection of the material with which parameters and performance are selected can be adapted according to the size and operation of the equipment. The above technical means can be effectively known by those skilled in the art, and the specific description is omitted. For the driving assembly 13, it realizes the reciprocating movement of the device in the horizontal direction by using a set of driving mechanism, which not only reduces the complexity of the device components, but also reduces the establishment of multiple driving parts, greatly improves the use functionality of the device, and meets the use requirements.

[0027] In order to guarantee the cleanness in the production and processing process, it is further pointed out that the outer side of the frame body 1 and the outer side of the shell 9 are provided with protective covers (not shown in the figure) to ensure the sealing of the device, and a dust removal assembly 18 is arranged above the hopper discharge assembly 5, which includes a hanger 181, and a conical dust cover 182 is arranged above the hanger 181, and a dust suction pipe 183 is arranged above the dust cover 182, which is specifically described as follows: the dust suction pipe 183 is connected with the external dust suction equipment, when the device is in production and processing, the external dust suction equipment is controlled to run, the dust generated by the material falling in the vibration mode of the hopper discharge assembly 5 is collected through the dust suction pipe 183 and the dust cover 182, the cleanness in the production and processing process is guaranteed, the working environment is not affected by the dust, and the safety hidden danger is reduced.
