[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1 and 2 As shown, this embodiment provides a material diverter, including a frame 1, a ball mesh chain conveying mechanism, and a diverting mechanism. The ball mesh chain conveying mechanism is arranged on the frame 1, and a plurality of diverting channels (not shown in the figure, located at Figure 1 In the lower left side of the middle part of the machine frame 1, a material sensor is provided at the diversion channel, and a group of diversion mechanisms are provided at the corresponding positions of each diversion channel in the frame 1. The diversion mechanism includes a ball friction belt 31 along the conveying mechanism of the ball mesh chain, and a diversion drive device driving the ball friction belt 31. A controller is connected between the material sensor and the diversion drive device at the corresponding position. Among them, the ball friction belt 31 is arranged along the width direction of the frame 1, and it cooperates with the lower side of the ball of the conveying surface of the ball mesh chain. When the ball friction belt 31 rotates on the side facing away from the diversion channel, the lower side of the ball is driven to roll against the diversion channel, thereby driving the ball of the ball mesh chain conveying mechanism to roll toward the side of the diversion channel, and transporting the material into the diversion channel. The working principle of the entire diverter is as follows: the material is transported along the length of the frame on the ball mesh chain conveying mechanism in turn, and each material sensor monitors the material situation in the diverter channel. When there is material in a diverter channel, the corresponding diverter mechanism remains stopped, and the material on the ball mesh chain continues to be transported forward; when there is no material in a diverter channel, the corresponding diverter mechanism is started to transport the material passing through it to the diverter channel. Therefore, this material diverter can distribute the material to each diverter channel in an orderly manner. The diverter channel is generally connected to the silo to avoid material congestion in the diverter channel.

[0028] Specifically, the frame 1 is provided with baffles 11 on both sides above the ball mesh chain conveying mechanism to prevent materials from falling, and correspondingly, the baffle 11 is provided with a notch 111 at the position corresponding to the diversion channel. In order to allow the material to pass through the notch more smoothly and enter the diversion channel, the two side edges of the notch 111 are provided with guide slopes, that is, the side of the notch 11 close to the inside of the frame 1 is wider than the other side.

[0029] like Figure 3As shown, the ball mesh chain conveying mechanism includes a transmission shaft 21 arranged at both ends of the frame, a plurality of gears 22 arranged at intervals on the transmission shaft, a ball mesh chain 23 that cooperates with the gears on the two transmission shafts, and a conveying drive device connected to one of the transmission shafts through a sprocket chain transmission, and the conveying drive device is generally a motor. In order to ensure the stability of the gear position and thus ensure the stability of the ball mesh chain, a positioning hoop 24 is provided on both sides of each gear 22 on the transmission shaft 21, and the positioning hoop 24 is tightly held on the transmission shaft, thereby limiting the gear 22 from sliding on the transmission shaft 21. Since the entire ball mesh chain is relatively long, in order to ensure that the ball mesh chain can always be in a horizontal state, a support frame 25 is provided under each layer of the ball mesh chain 23. Of course, no support frame is provided at the part where the upper ball mesh chain 23 cooperates with the ball friction belt 31, and the support there is provided by the friction belt and other components of the diversion mechanism.

[0030] like Figure 4 As shown, the diversion mechanism specifically includes a support frame 32, an active roller 33 and two driven rollers 34 arranged in the support frame, the output end of the diversion drive device is connected to the active roller 33, and the ball friction belt 31 surrounds the active roller 33 and the two driven rollers 34. Among them, the diversion drive device is generally a motor, the two driven rollers 34 are arranged at both ends of the support frame, and the active roller 33 is arranged at the lower middle position to avoid the diversion drive device being too high and interfering with the ball mesh chain 23. In order to ensure that the ball friction belt 31 can always be closely matched with the ball mesh chain 23, a support plate 35 is provided below the upper layer of the ball friction belt 31 in the support frame 32 to prevent the ball friction belt from sinking. At the same time, tensioning rollers 36 are provided on both sides of the active roller 33, and the tensioning rollers 36 cooperate with the outer side of the ball friction belt 31 to ensure the tension of the ball friction belt and ensure the stability of the transmission between it and the ball.

[0031] Finally, considering that all the diversion channels are busy and fail to output materials in time, resulting in material accumulation at the end of the ball mesh chain, a discharge port 4 is provided at the downstream end of the frame 1 to timely output materials that have not been distributed in time.

[0032] The above is only a preferred specific implementation of the utility model, which is a realization method based on the overall concept of the utility model, and the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
