[0022] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1 Please refer to Figures 1 to 11The present invention proposes a fully automatic intelligent material dividing equipment, including: a three-way material dividing machine 1, a feeding port 101 is arranged above the three-way material dividing machine 1, the feeding port 101 is connected to the feeding belt conveyor 2, two material dividing chutes 102 are arranged below the openings of the two material dividing chutes 102, respectively, a downstream belt conveyor 4 is arranged below the openings of the two material dividing chutes 102, a material dividing channel frame 3 is respectively installed at the lower end openings of the two material dividing chutes 102 by bolts, the downstream belt conveyor 4 is movably connected to the inside of the material dividing channel frame 3, a belt weighing device 5 is fixedly connected to the inside of the material dividing channel frame 3, and a belt weighing device 5 is fixed above the belt weighing device 5. The downstream belt conveyor 4 is connected, and the two belt weighers 5 are connected to the control display panel 6 through a data line. The control display panel 6 is fixedly connected to the front surface of the three-way distributor 1. The outer wall of the distributor chute 102 is provided with a gate socket 103, and the gate socket 103 is fixedly connected to the gate guide frame 104. The gate guide frame 104 is equipped with a flat gate platform, which includes a flat gate 7 and a gate push cylinder 8. The flat gate 7 is movably connected to the gate socket 103 and the gate guide frame 104. The gate push cylinder 8 is fixedly connected to the outer end surface of the gate guide frame 104 by bolts. The push rod is fixedly connected to the outer edge of the flat gate 7; a group of flat gate platforms are respectively arranged on the two material distribution chutes 102. Through the action of the flat gate platforms, the gate push cylinder 8 controls the length of the flat gate 7 inserted inside the material distribution chute 102, controls the flow area of ​​the material distribution chute 102, and then controls the flow of materials in the material distribution chute 102. The two belt weighers 5 send the weight data of the materials to the control display panel 6 through the data line. The control display panel 6 detects whether the weight data measured by the two belt weighers 5 conforms to the set data, and controls the gate push cylinder 8 to act. When one of the material distribution chutes When the data measured by the belt weighing device 5 below the tube 102 is less than the set value, the gate push cylinder 8 on the distribution chute 102 is controlled to contract through the control display panel 6, and the flat gate 7 is pulled outward, thereby increasing the flow area of ​​the distribution chute 102, so that more materials can flow out through the distribution chute 102; on the contrary, if the measured weight of the downstream belt conveyor 4 is greater than the set value in the control display panel 6, the flat gate 7 can be pushed into the inside of the distribution chute 102 through the gate push cylinder 8, thereby reducing the flow of materials in the distribution chute 102 and reducing the total amount of material diversion outflow.

[0024] In the disclosed embodiment, a dividing material control push cylinder 10 is fixedly connected to the outer surface of the three-way dividing machine 1, and the push rod end of the dividing material control push cylinder 10 is fixedly connected to an "L"-shaped dividing structure 9, and the dividing structure 9 is slidably connected in the middle of the upper ends of the two dividing material chutes 102 inside the three-way dividing machine 1, and the gate push cylinder 8 and the dividing material control push cylinder 10 are connected to the control display panel 6 through a data line; through the cooperation between the dividing structure 9 and the dividing material control push cylinder 10, when the two belt weighers 5 detect that the material dividing of the two downstream belt conveyors 4 is seriously unbalanced, the dividing material control push cylinder 10 can be controlled by the control display panel 6 to control the action of the dividing material control push cylinder 10, and control the dividing structure 9 to move in the direction of the dividing material chute 102 where the material dividing amount needs to be reduced, and control the proportion of the material entering the dividing material chute 102, thereby further improving the accuracy of material dividing.

[0025] In the disclosed embodiment, a transverse guide rod 105 is fixedly connected to the front wall and the rear wall inside the three-way distributor 1, respectively. The transverse guide rod 105 is located at the upper end of the two distributor chutes 102. A distributor guide groove 901 is respectively opened in front and rear of the distributor structure 9, and the distributor guide groove 901 is slidably connected to the transverse guide rod 105. The sliding connection between the distributor guide groove 901 and the transverse guide rod 105 plays a guiding role, thereby preventing the distributor structure 9 from tilting or swinging during the translation process, which may cause an imbalance in the distribution amount.

[0026] In the disclosed embodiment, the inner side wall of the distribution chute 102 is an inner chute wall 106 with a stepped structure; after the material enters the distribution chute 102, it falls obliquely downward along the obliquely arranged distribution chute 102. Through the setting of the inner chute wall 106, the material collides with the inner chute wall 106, and the material rolls downward along the stepped structure of the inner chute wall 106, thereby reducing the impact of the material falling on the downstream belt conveyor 4, and reducing the fluctuation of the value measured by the belt weigher 5 caused by the impact of the falling material.

[0027] In the embodiment of the present disclosure, a material distribution port 301 is provided above the material distribution channel frame 3, and two inclined guide plates are provided below the material distribution port 301, and the inclined guide plates are located above the downstream belt conveyor 4. Two vertical guide rods 302 are fixedly connected to the two side walls inside the material distribution channel frame 3 respectively; a belt conveyor drag platform 401 is fixedly connected to the outside of the bracket of the downstream belt conveyor 4, and a guide slider 402 is fixedly connected to the left and right walls of the belt conveyor drag platform 401 by bolts, and the guide slider 402 is slidably connected to the vertical guide rod 302, and the bottom surface of the belt conveyor drag platform 401 is fixedly connected to the upper end of the belt weighing device 5, and the downstream belt conveyor 4 is supported and guided by the material distribution channel frame 3, and the belt weighing device 5 accurately detects the total weight of the material dropped above the downstream belt conveyor 4, accurately calculates the material distribution amount, and ensures that the downstream belt conveyor 4 runs in parallel. In actual use, the downstream belt conveyor 4 cannot be used as the main feeding device after material distribution, and an external feeding device should be connected to the rear end of the downstream belt conveyor 4 to transport the material after material distribution over a long distance.

[0028] Embodiment 2 On the basis of Example 1, the inner lower edge of the distribution chute 102 is rotatably connected to two deceleration inclined plates 11 through bearings, and the two deceleration inclined plates 11 are arranged front to back, and the lower edge of the front deceleration inclined plate 11 is higher than the lower edge of the rear deceleration inclined plate 11; the two ends of the support shaft of the deceleration inclined plate 11 are respectively fixedly connected with a buffer coil spring 1101, and the buffer coil spring 1101 is fixedly connected to a limiting end cylinder 1102 outside, and the limiting end cylinder 1102 is fixedly connected to the outer surface of the distribution chute 102; the deceleration inclined plate 11 is inclined toward the rear and lower side, and the deceleration inclined plate 11 is located above the downstream belt conveyor 4. Under normal circumstances, the deceleration inclined plate 11 is limited by the buffer coil spring 1101 and the limiting end cylinder 1102. Maintain a fixed angle, and when the deceleration inclined plate 11 is subjected to a large impact, the buffer coil spring 1101 will be compressed to cause the deceleration inclined plate 11 to swing and rotate, and finally restore to the original angle through the elastic action of the buffer coil spring 1101, thereby playing a buffering role and reducing the impact of the material on the deceleration inclined plate 11 at the moment of falling. After the material falls through the material distribution chute 102, it falls on the two obliquely arranged deceleration inclined plates 11, and slides backward and downward with the deceleration inclined plates 11 and falls on the top of the downstream belt conveyor 4, which can further reduce the impact of the material falling on the top of the downstream belt conveyor 4, and reduce the floating and instability of the value measured by the belt weigher 5 caused by the impact of the material falling.

[0029] The working principle of this embodiment is as follows: first, the required amount of material to be distributed is input into the control display panel 6, and the feeding belt conveyor 2 is started. The material to be distributed is transported into the three-way distributor 1 through the feeding belt conveyor 2. After the material enters the three-way distributor 1, it is diverted through the distribution structure 9, and is divided into two paths to enter the distribution chute 102 respectively, and finally falls on the top of the two downstream belt conveyors 4. The weights of the two downstream belt conveyors 4 are tested respectively by the belt weighing device 5, and then the total weight of the materials above the two downstream belt conveyors 4 is accurately measured. The distribution amount is calculated by the weight of the material, which can better improve the statistics of the material distribution flow rate. When the data measured by the belt weighing device 5 below one of the distribution chutes 102 is less than the set value, the distribution chute 102 is controlled by the control display panel 6. The gate push cylinder 8 on the upper part contracts, pulling the flat gate 7 outward, increasing the flow area of ​​the distribution chute 102, so that more materials can flow out through the distribution chute 102; on the contrary, if the measured weight of the downstream belt conveyor 4 is greater than the set value in the control display panel 6, the flat gate 7 can be pushed into the distribution chute 102 by the gate push cylinder 8, reducing the flow of materials in the distribution chute 102 and the total amount of material diversion outflow. When the two belt weighers 5 detect that the material distribution of the two downstream belt conveyors 4 is seriously unbalanced, the control display panel 6 can be used to control the distribution control push cylinder 10 to control the distribution structure 9 to move in the direction of the distribution chute 102 where the material distribution amount needs to be reduced, thereby controlling the proportion of the material entering the distribution chute 102 and improving the accuracy of material distribution.
