Description

Technical Field

[0001] The invention relates to the technical field of fertilizer transportation, in particular to an automatic conveyor for compound fertilizer production. Background Art

[0002] Compound fertilizer, as a fertilizer product that integrates two or more key nutrients, plays a vital role in agricultural production due to its high nutrient content, low proportion of by-products and excellent physical properties. It has irreplaceable value in achieving precise fertilization, improving fertilizer utilization efficiency and ensuring sustained high and stable yields of crops.

[0003] In the production process of compound fertilizer, a series of sophisticated process steps ensure the final quality of the product, including precise proportioning and mixing of raw materials, efficient granulation process, necessary cooling treatment and strict screening and grading. In particular, compound fertilizer after granulation is prone to agglomeration due to the influence of temperature residue and moisture content. Therefore, the cooling step is particularly important. It can effectively reduce the material temperature and reduce agglomeration. However, even after cooling, a small amount of fertilizer particles will still agglomerate for various reasons or the size does not meet the standard. This requires multiple screening to accurately remove these unqualified products.

[0004] However, there is an urgent problem to be solved in the current screening process: all cooled compound fertilizers are directly sent to the screening equipment through the conveyor belt (2). During this process, a large number of qualified fertilizer particles will be squeezed, collided and rubbed against each other unnecessarily, which may not only cause surface damage to the fertilizer particles and affect the yield rate, but also increase the generation of debris, resulting in waste of resources and consumption of additional energy. Therefore, we propose an automatic conveyor for compound fertilizer production. Summary of the invention

A vibrating screen is arranged at the tail end of the conveyor belt 2, and the processed compound fertilizer is pre-screened by the vibrating screen, and then the unqualified fertilizer is sent to the subsequent screening machine, and also comprises a partition plate 3 and an outer cover 4, the outer cover 4 is fixedly arranged on the conveyor frame 1, the partition plate 3 is arranged inside the outer cover 4 and is located above the conveyor belt 2, and can divert the conveyed compound fertilizer, and a plurality of notches 5 are opened at the front end of the partition plate 3, some fertilizer particles and some small pieces of agglomerated fertilizer can continue to stay on the conveyor belt 2 through the notches 5, while some larger agglomerated fertilizers move along the partition plate 3 to the top thereof;

[0040] It also includes a toggle roller 6 rotatably arranged on the inner side of the outer cover 4, which is located at the notch 5 at the front end of the partition plate 3. The toggle roller 6 is in transmission connection with the conveyor belt 2. The large agglomerated fertilizer can be toggled onto the partition plate 3 by the toggle roller 6 to prevent it from accumulating at the notch 5 and affecting continuous conveying. A reciprocating extrusion mechanism 7 is arranged at the bottom of the partition plate 3 to extrude the compound fertilizer with smaller agglomerates on the conveyor belt 2 to separate them.

[0041] The partition plate 3 is provided with a spring plate 10 and a rolling assembly 8. The spring plate 10 is rotatably arranged on the partition plate 3, and the rolling assembly 8 is arranged at the end of the partition plate 3. The compound fertilizer with large lumps transported to the partition plate 3 is bounced up and falls on the partition plate 3 again when passing through the spring plate 10, and is initially crushed by the gravity potential energy, and then crushed by the rolling assembly 8;

[0042] A driving structure 9 is arranged above the conveyor belt 2 , and the driving structure 9 is transmission-connected with the reciprocating extrusion mechanism 7 , the rolling assembly 8 and the spring plate 10 .

[0043] The partition plate 3 is provided with three sections along the conveying direction, namely a conveying section 31 , a connecting section 32 and a rolling section 33 . The spring plate 10 is rotatably provided at the end of the conveying section 31 , and the rolling assembly 8 is provided at the rolling section 33 .

[0044] The toggle roller 6 includes a toggle shaft 61 rotatably arranged on the inner side of the outer cover 4, sprocket wheels 62 are installed at both ends of the toggle shaft 61, and chains 63 are fixedly installed on both sides of the conveyor belt 2. The chain 63 is meshed with the sprocket wheel 62, and can drive the chain 63 to move with the conveyor belt 2 when conveying, thereby driving the sprocket wheel 62 to rotate, and the sprocket wheel 62 drives the toggle shaft 61 to rotate, so that the toggle lever 64 toggle the fertilizer with larger agglomerates onto the partition plate 3;

[0045] A plurality of levers 64 are provided on the outside of the toggle shaft 61. The plurality of levers 64 are installed in a circular array on the outside of the toggle shaft 61. When rotating, the plurality of levers 64 pass through the slot 5 of the partition plate 3, thereby shifting the fertilizer with larger lumps accumulated at the slot 5, so that qualified granular fertilizer and fertilizer with smaller lumps can pass through the slot 5.

[0046] The lever 64 includes a fixed rod 641 fixedly arranged on the outside of the toggle shaft 61, a sliding rod 642 is slidably arranged inside the fixed rod 641, and a connecting spring 643 is arranged at one end of the sliding rod 642 located inside the fixed rod 641, and both ends of the connecting spring 643 are respectively fixedly connected to the sliding rod 642 and the inside of the fixed rod 641. The lever 64 is designed as an elastic rod. When the toggle shaft 61 rotates to drive the lever 64 to move and abuts against the conveyor belt 2, the sliding rod 642 will shrink into the fixed rod 641. When the lever 64 continues to rotate, its end gradually moves away from the conveyor belt 2. Under the action of the connecting spring 643, the sliding rod 642 extends out, so that the end of the sliding rod 642 can extend into the slot 5, thereby achieving a better toggle effect on the fertilizer with larger clumps, ensuring that it can be transported to the partition plate 3.

[0047] The reciprocating extrusion mechanism 7 includes a moving rod 1 71 and a moving rod 2 72. The moving rod 1 71 and the moving rod 2 72 are provided in multiple numbers and are staggered with each other. The bottom sides of the moving rod 1 71 and the moving rod 2 72 are fixedly provided with a cross rod 73. The middle of the cross rod 73 is fixedly connected with a cross rod 74. The inner side of the outer cover 4 is movably provided with a transmission rod 1 75 and a transmission rod 2 76. The multiple moving rods 1 71 are fixedly connected to the transmission rod 1 75, and the multiple moving rods 2 72 are fixedly connected to the transmission rod 2 76. Both ends of the transmission rod 1 75 and the transmission rod 2 76 are provided with elastic extension rods. The retractable rod 77, the other end of the elastic telescopic rod 77 is connected to the inner wall of the outer cover 4. When the moving rod 1 71 and the moving rod 2 72 move back and forth respectively, the cross rods 73 arranged thereon will periodically approach and move away from each other, and there are gaps between the cross rods 73, which can ensure that normal granular fertilizers can pass through, so that some agglomerated fertilizer blocks are squeezed by the cross rods 73 and the cross rods 74 on both sides, so that the agglomerates are crushed. Since the fertilizers left on the conveyor belt 2 are relatively small, they are simply processed by this reciprocating squeezing method to avoid too much wear between the fertilizers.

[0048] The spring plate 10 is rotatably arranged on the partition plate 3 via a rotating shaft, and a protrusion 11 is fixedly arranged at the bottom of the spring plate 10. A limit plate for limiting the spring plate 10 is fixedly arranged at the bottom of the partition plate 3. The limit plate can ensure that the spring plate 10 remains overlapped with the partition plate 3 when it is at the lowest position.

[0049] The driving structure 9 includes a motor fixedly mounted on the outer cover 4, the output end of the motor is connected to a driving shaft 91, a cam 92 is fixedly arranged on the outer side of the driving shaft 91, and the cam 92 is located below the spring plate 10. The rotation of the motor drives the driving shaft 91 to rotate, and the driving shaft 91 drives the cam 92 to rotate continuously. When the cam 92 contacts the protrusion 11, it can drive the protrusion 11 to move, thereby driving the spring plate 10 to pop up.

[0050] The rolling assembly 8 includes a pressure roller 81 rotatably arranged on the inner side of the outer cover 4, a plurality of pressure blocks 82 are fixedly arranged on the outer side of the pressure roller 81, pulleys are arranged on the outer side of the driving shaft 91 and the rotating shaft of the pressure roller 81, and a belt is arranged on the outer side of the pulley. The driving shaft 91 and the pressure roller 81 are driven to rotate synchronously through the belt transmission, and the pressure blocks 82 arranged on the pressure roller 81 are driven by the rotation of the pressure roller 81 to roll the fertilizer with larger lumps.

[0051] A connecting plate 19 is slidably provided on the inner side of the outer cover 4, a vertical rod 12 is fixedly provided on the inner wall of the outer cover 4, the vertical rod 12 movably penetrates the connecting plate 19, a supporting spring 13 is provided on the outer side of the vertical rod 12, and both ends of the supporting spring 13 are fixedly connected to the connecting plate 19 and the outer cover 4 respectively, a top plate 14 is fixedly provided on the middle section of the connecting plate 19, one end of the top plate 14 is located at the bottom of the cam 92 and is provided with a fixed block 15, an inclined block 16 is provided at the bottom of the top plate 14, two inclined blocks 16 are provided and are respectively located above the transmission rod 1 75 and the transmission rod 2 76, and a through groove 17 cooperating with the inclined block 16 is opened on the transmission rod 1 75 and the transmission rod 2 76, and when the inclined block 16 moves down, it can It drives transmission rod 1 75 and transmission rod 2 76 to move opposite to each other. When cam 92 rotates, it can periodically squeeze fixed block 15, thereby driving top plate 14 to move downward. When top plate 14 moves downward, it drives connecting plate 19 and inclined block 16 to move, thereby driving transmission rod 1 75 and transmission rod 2 76 to move opposite to each other. When transmission rod 1 75 and transmission rod 2 76 move, they can drive cross rod 73 to move back and forth to squeeze small lumps. Due to the limitation of notch 5, fertilizer will be separated into multiple strips on conveyor belt 2 when transported to the bottom of partition plate 3. Fertilizer can also be flattened by movement of cross rod 73 to ensure that fertilizer is evenly spread to avoid re-agglomeration.

[0052] In summary, compound fertilizer is input from one end of the conveyor belt 2. As the conveyor belt 2 moves, the fertilizer particles are conveyed to the partition plate 3. Small granular fertilizers and small agglomerated fertilizers continue to remain on the conveyor belt 2 through the slot 5 at the front end of the partition plate 3, while large agglomerated fertilizers are moved to the partition plate 3 by the moving roller 6. On the partition plate 3, the large agglomerated fertilizers are initially broken into smaller blocks after being bounced by the spring plate 10 and rolled by the rolling component 8. At the same time, the small agglomerated fertilizers remaining on the conveyor belt 2 are squeezed by the reciprocating squeezing mechanism 7 to separate them into smaller particles. Finally, the processed fertilizer particles are conveyed to the vibrating screen and screened by the vibrating screen. The unqualified fertilizers are then sent to the subsequent screening machine, which avoids the problem that qualified products enter the subsequent crushing and screening machine and are then damaged by friction and squeezing.

[0053] Example 2: Please refer to Fig.13 The main structure of Example 2 is the same as that of Example 1. On the basis of Example 1, a top block 18 is added. A plurality of top blocks 18 are fixedly arranged on the surface of the rolling section 33 of the partition plate 3. Large agglomerates are bounced up after passing through the spring plate 10 and then fall onto the top block 18, thereby achieving a better initial crushing effect.

[0054] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
