In the middle of a support frame 33, two raised blocks at the other end are fixedly connected to the support legs 36. In a normal state, the first support frame 33 is in an inclined state. When the second cylinder 30 drives the light rod 34 to move forward, since the horizontal height of the light rod 34 does not change, when the bottom of the first support frame 33 moves toward the direction of the raised block 32, the first support frame 33 gradually tends to a vertical state, so that the first support frame 33 will drive the conveying mechanism 2 at one end of the lifting mechanism 29 to lift upward.

At this time, the baffle mechanism 17 is in an open state. When the conveying mechanism 2 conveys the raw materials falling from the first discharge port 7, the first cylinder 12 will contract, and the push plate 14 will move backward. The rear opening 15 moves to the rear of the first discharge port 7. The surface of the push plate 14 can block the first discharge port 7, and the raw materials inside the first discharge bin 6 will not flow out. At the same time, the front opening 15 moves to the second discharge port 9. The second discharge port 9 is in an open state, and the raw materials inside the first discharge bin 6 can flow out from the second discharge port 9, so that when the raw materials falling from the first discharge port 7 move to the front of the second discharge port 9 When the conveying mechanism 2 is in the downward direction, the second material discharge port 9 is in an open state, and the raw materials dropped from the second material discharge port 9 will cover the surface of the raw materials dropped from the first material discharge port 7, and at the same time, the push plate 14 will drive the connecting bar 16 to move backward, and at the same time, the connecting bar 16 will drive the pin to move backward, and the pin will have a pulling effect on the first connecting rod 20 and the second connecting rod 21 backward, and the other ends of the first connecting rod 20 and the second connecting rod 21 will respectively pull the baffle plates 19 on both sides, and the front end of the baffle plate 19 will move toward the center of the conveying mechanism 2. At this time, the baffle mechanism 17 is in a closed state, and when the conveying mechanism 2 is transmitting the raw materials, the raw materials will be blocked by the two baffle plates 19, and at the same time, the baffle plates 19 will guide the raw materials, and the raw materials will gather at the center of the conveying mechanism 2, and the above work will be repeated. When the baffle mechanism 17 When the material is in the open state, the gathered raw materials can be transmitted forward. When the gathered raw materials are transported to the bottom of the mixing drum 26, the mixing drum 26 can break up the raw materials during the rotation to achieve preliminary mixing of the two raw materials. Finally, under the action of the inclined plate 37, the raw materials can fall from the inclined plate 37 into the feeding port of the spiral feeding mechanism, and then be transported by the spiral feeding mechanism. The spiral feeding mechanism can effectively prevent dust and material scattering and waste. When the second cylinder 30 drives the light rod 34 to move forward, since the horizontal height of the light rod 34 does not change, when the bottom of the first support frame 33 moves toward the direction of the protrusion 32, the first support frame 33 gradually tends to a vertical state, so that the first support frame 33 will drive the conveying mechanism 2 at one end of the lifting mechanism 29 to lift upward.The inclined conveying mechanism 2 can reduce the friction between the raw material and the conveyor belt, reduce energy loss, improve the conveying efficiency, and effectively prevent the backflow of raw materials caused by gravity during the conveying process.
