Description

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] See also Figure 1-Figure 3 as well as Figure 7 An embodiment of the present invention provides a suspension conveying mechanism for preparing a urea solution raw material, comprising a bracket 1, a urea bag 2, and a straight track 3 and a curved track 39. Both the straight track 3 and the curved track 39 are arranged on the bracket 1. A plurality of pulleys 11 are rotatably mounted on the straight track 3, and the plurality of pulleys 11 are also rotatably mounted within the curved track 39. When straight travel is required, the plurality of pulleys 11 rotate within the straight track 3. When turning is required, the plurality of pulleys 11 rotate within the curved track 39. A connecting shaft is rotatably mounted between every two pulleys 11, and a connecting frame 12 is fixedly mounted between the two connecting shafts.

[0038] It also includes a connecting block 18, which is connected to the connecting frame 12 through a stabilizing structure, and the stabilizing structure is used to stabilize the urea bag 2 during transportation; the stabilizing structure includes a plurality of damping bearings rotatably mounted on the connecting frame 12, and a rotating shaft 19 is rotatably mounted between each two damping bearings, and a fixing plate 20 and two gears 25 are fixedly mounted on the two rotating shafts 19, and a plurality of arcuate gear rods 22 are fixedly mounted on the connecting block 18, and each arcuate gear rod 22 is meshed with a corresponding gear 25, and a spring 21 is fixedly mounted between the two fixing plates 20 and the connecting block 18.

[0039] When the urea bag 2 is started and stopped during transportation, the urea bag 2 may produce a preliminary swing due to inertia. This swing may increase the burden on the connecting block 18 in some cases, especially the rotating rod 24, which is prone to displacement or wear. When the urea bag 2 swings, it will squeeze the spring 21 on the corresponding side through the connecting block 18, and at the same time drive the arc-shaped gear rod 22 to engage with the gear 1 25, so that the rotating shaft 19 drives the fixed plate 20 to rotate. When the spring 21 is squeezed by the connecting block 18, the corresponding rotating shaft 19 will drive the fixed plate 20 to squeeze the spring 21. When the second spring 21 is pulled by the connecting block 18, the corresponding rotating shaft 19 will drive the fixing plate 20 to rotate in the direction of the stretched spring 21, thereby counteracting the squeezing force at the other end of the second spring 21. At the same time, when the second spring 21 on the other side is stretched by the connecting block 18, the corresponding rotating shaft 19 will drive the fixing plate 20 to rotate in the direction of the stretched spring 21, thereby exerting a certain restraining effect on the connecting block 18, causing it to return to a vertical state, thereby reducing the shaking caused by the urea bag 2. Under the buffering of the damping bearing and the second spring 21, the swing amplitude of the urea bag 2 is controlled, thereby reducing its vibration amplitude and frequency, helping to absorb the impact generated during the starting and stopping process, and reducing the burden on the rotating rod 24.

[0040] See also Figure 6-Figure 8 , also includes a balancing structure, which is installed between the connecting frame 12 and the curved track 39 for use in conjunction with each other to maintain the horizontal stability of the urea bag 2 when traveling on the curved track 39; the balancing structure includes a sliding hole 29 opened on the connecting frame 12, and a rotating rod 24 is rotatably and slidably installed in the sliding hole 29, and a clamping rod is fixedly provided at both ends of the rotating rod 24, and the clamping rod is arranged in a vertical state to the ground, a square block 23 is fixedly provided on the rotating rod 24, and the connecting block 18 is slidably provided on the square block 23, two fixed blocks 26 are fixedly installed on both sides of the connecting frame 12, each fixed block 26 is fixedly provided with a spring three 28, and one end of each spring three 28 is fixedly provided with a wedge block 27, and each wedge block 27 slides on the connecting frame 12, and multiple wedge blocks 27 cooperate to limit the rotating rod 24, a trigger plate 30 is fixedly installed on the curved track 39, and the rotating rod 24 slides on the trigger plate 30 for use, and an arc-shaped sliding groove is provided on the trigger plate 30.

[0041] The straight track 3 and the curved track 39 are fixedly connected, and the connection between the straight track 3 and the curved track 39 is a smooth transition, which can enable the pulley 11 to slide smoothly between the two (only schematically shown in the figure); the interior of the curved track 39 is sloped, and the height of the outer side of the interior of the curved track 39 is higher than the height of the inner side, which is used to overcome the centrifugal force generated by the pulley 11 (when the urea bag 2 turns in a curve, the centrifugal force generated will cause the pulley 11 to lean to the outside, acting on the outer side of the curved track 39, increasing the lateral force at the curved track 39). A plurality of fixed frames 1 are fixedly installed in the curved track 39, and auxiliary wheels 1 31 are rotatably installed on the plurality of fixed frames 1. The auxiliary wheels 1 31 are used to support the inner pulley 11. When traveling on a curve, the inner pulley 11 is subjected to a large lateral force and is prone to side slipping or losing traction. With the assistance of the auxiliary wheels 1 31, the inner pulley 11 can better maintain traction, reduce lateral slippage of the pulley 11, and improve the overall transportation stability of the urea bag 2.

[0042] A reduction wheel 32 is fixedly installed on both connecting shafts, and a plurality of fixed frames 2 are fixedly installed in the curved track 39. A sliding groove plate 37 is fixedly provided on each of the fixed frames 2. A sliding block is slidingly installed between every two sliding groove plates 37. An auxiliary wheel 2 38 is rotatably provided between every two sliding blocks. A spring 4 36 is fixedly provided on each sliding block. An extrusion groove is provided in the curved track 39, and a piston plate 35 is sealingly sliding in the extrusion groove. The piston plate 35 is fixedly arranged between each spring 4 36. A square tube 34 connected to the extrusion groove is fixedly provided in the curved track 39, and the lower port of the square tube 34 is located in the curved track 39. A sealing plate is sealingly sliding at the lower port of the square tube 34. A plurality of reduction plates 33 are fixedly installed on the sealing plate, and hydraulic oil is filled between the square tube 34 and the extrusion groove.

[0043] When the pulley 11 travels at too high a speed and deviates inside the curved track 39, it squeezes the auxiliary wheel 2 38. The spring 4 36 on the auxiliary wheel 2 38 has a certain elasticity, but the hardness is large enough to make the spring 4 36 squeeze the piston plate 35 to move it upward, and the hydraulic oil flows accordingly, driving the sealing plate to move upward, so that the multiple speed reduction plates 33 are in contact with the speed reduction wheel 32. The speed reduction plates 33 and the speed reduction wheel 32 are made of elastic materials, such as rubber, which can achieve a certain deceleration effect without affecting the operation of the pulley 11, preventing it from being hard damaged, and ensuring the stability of the urea bag 2 when moving; in the curved track 39 During driving, the card rod will slide along the arc chute. As the angle increases, the card rod drives the connecting block 18 to continue to maintain a horizontal state through the rotating rod 24. During the process of the card rod moving upward relatively in the arc chute, it will squeeze the corresponding two wedge blocks 27, causing them to shake to a certain extent between the two springs 28, preventing the card rod and the rotating rod 24 from being damaged. At the same time, the setting of the wedge blocks 27 can play a certain limiting role on the card rod to prevent it from swaying left and right. The bottom of the card rod is set as a universal ball, which can reduce the friction of its sliding in the arc chute, thereby ensuring the stable transportation of the urea bag 2.

[0044] See also Figure 2-Figure 5 , also includes a connecting disk 17, which is fixedly mounted on the connecting block 18; a speed regulating and mixing structure, which is mounted on the connecting disk 17 and is used to adjust the outflow speed of urea in the urea bag 2. A plurality of hanging straps 6 are fixedly provided above the urea bag 2, and a plurality of pull ropes 4 are fixedly provided on the lower surface of the urea bag 2; the speed regulating and mixing structure includes a plurality of adjusting ropes 8 arranged on the side of the connecting disk 17, and a winding rod 14 is fixedly mounted on the lower ends of every two adjusting ropes 8. Gears 2 are fixedly mounted on both ends of the two winding rods 14, and mounting blocks are rotatably mounted on both ends of the two winding rods 14. A connecting platform 13 is fixedly mounted between the multiple mounting blocks, and two shielding covers 5 are fixedly mounted on the connecting platform 13, and the two winding rods 14 are respectively located in the corresponding shielding covers 5. A mounting hole is provided on the connecting platform 13, in which multiple gears three are rotatably installed, and multiple gear rods 2 16 are slidably installed in the mounting hole. The upper end of each pull rope 4 is fixed to the corresponding gear rod 2 16, and each gear three is meshed with the corresponding gear rod 2 16. One end of multiple gear rods 2 16 is fixedly installed with a vertical rod, and the upper ends of multiple vertical rods are fixedly installed with a gear rod 15, and each gear rod 15 is meshed with the corresponding gear 2. A hanging rod 7 is fixedly installed on each gear three, and each hanging belt 6 is hung on the hanging rod 7. A spring 1 9 is fixedly installed between every two hanging rods 7. A support rod 10 is rotatably installed on each hanging rod 7, and a rotation setting is set between every two support rods 10. The two support rods 10 support the two hanging rods 7.

[0045] The multiple hanging straps 6 on the urea bag 2 are hung on the corresponding hanging rods 7 respectively. In the initial state (the urea in the urea bag 2 is full of urea), the corresponding two hanging rods 7 are close to each other. At this time, the spring 1 9 is in a compressed state, and the multiple drawstrings 4 are tightened on the lower opening of the urea bag 2. When the urea bag 2 is opened to release the urea therein, as the urea continues to flow out, its weight is reduced. Under the action of the spring 1 9, the corresponding two hanging rods 7 are driven away from each other. At this time, the gear rod 2 16 is driven by the gear 3 to slide in the direction away from each other, and the multiple drawstrings 4 are loosened on the lower opening of the urea bag 2. At this time, the lower opening of the urea bag 2 gradually increases during the urea outflow process. , it can avoid urea being concentrated in a small area, thereby reducing the unstable flow rate caused by local accumulation, gradually expanding the outlet area according to the weight of the urea bag 2, and at the same time, the upper part of the urea bag 2 is opened to facilitate the flow of air into the bag (ensuring a certain opening on the top to allow air to flow in), forming a certain airflow, which can reduce the negative pressure effect caused by pouring urea (for example, the air in the bag is extracted), avoid the bag opening from shrinking, resulting in uneven or slow urea flow, and by providing sufficient space, the material can flow out more smoothly to achieve a balanced flow rate; when the urea in the urea bag 2 gradually flows out, as the weight decreases, multiple racks When the second gear 16 moves, the vertical rod drives the gear rod 15 to move, and the gear rod 15 moves and drives the winding rod 14 to rotate through the gear 2 to tighten the adjusting rope 8. The tightening of the adjusting rope 8 drives the urea bag 2 to rise, so that the urea bag 2 gradually rises as the accumulated height of urea poured out from the bottom, thereby improving the efficiency of urea pouring out. At the same time, the distance between the urea and the bottom can be controlled to prevent the urea from splashing or spilling during the pouring process. When the urea in the urea bag 2 flows out unbalancedly (the weight distribution at the four corners of the bag is uneven), the winding lengths of the multiple adjusting ropes 8 are adjusted accordingly with the weight distribution, and the winding length of the adjusting rope 8 on the heavier side is smaller than that on the lighter side. The winding length of the adjusting rope 8 is adjusted so that the heavier side is in a horizontally low position and the lighter side is in a horizontally high position. For example, if there are more urea granules on the left side, the right side is raised higher, which can help the urea granules flow out more evenly from both sides, because raising the right side will make the urea granules more likely to tilt to the right under the action of gravity, thereby balancing the pouring speed on both sides and having a mixing effect. The change in the winding length between the adjusting ropes 8 can produce a slight shaking, which helps to rearrange and distribute the urea in the bag. Through shaking, the urea can be more evenly distributed near the bag opening, avoiding the urea from being stuck at the bag opening or difficult to pour out smoothly.

[0046] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
