Description

Technical Field

[0001] The invention relates to the technical field of compound fertilizer processing, in particular to a compound fertilizer vibrating screen feeding mechanism. Background Art

[0002] Compound fertilizer, as one of the indispensable important fertilizers in modern agricultural production, is a scientific mixture of two or more nutrients in a certain proportion. The types and proportions of these nutrients are carefully formulated to meet the growth needs of crops and adapt to soil conditions and climatic conditions. Compound fertilizer plays a vital role in agricultural production with its comprehensive nutrients, reasonable ratio, long-lasting fertilizer effect, and easy use.

[0003] In the production process of compound fertilizer, vibration screening is a crucial link. Through vibration screening, the uniformity of compound fertilizer particles can be significantly improved, ensuring the balanced absorption of nutrients by crops; at the same time, it can also effectively remove impurities such as dust and fragments, thereby ensuring the purity and quality of the fertilizer. However, in the vibration screening process of compound fertilizer, due to the particularity of the properties of compound fertilizer itself, it is very easy to absorb water in the air, resulting in a significant increase in fertilizer humidity. This will not only cause the fertilizer particles to stick to each other due to excessive humidity, forming clumps that are difficult to separate, thereby greatly reducing the screening efficiency; it will also increase the risk of clogging of the vibrating screen mesh. When the screen is clogged, it can only be shut down and manually cleaned, which seriously hinders the fertilizer screening process and has an adverse effect on the overall operating efficiency. For this reason, we propose a compound fertilizer vibration screen feeding mechanism. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments 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.

[0034] Example 1: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: a compound fertilizer vibrating screen feeding mechanism, comprising a feeding device 1, a feeding bin 2 used in conjunction with the vibrating screen, and a material guide bin 3 arranged below the feeding bin 2, and also comprising a crushing rod 4, wherein the crushing rod 4 is located in the material guide bin 3, the crushing rod 4 is a triangular rod, and the crushing rod 4 is provided with a plurality of them; a cleaning ball 5, wherein the cleaning ball 5 is located on the material guide bin 3, the cleaning ball 5 is made of rubber, and the cleaning ball 5 is provided with a plurality of them.

[0035] The crushing driving unit 6 is arranged on the material guide bin 3, and the crushing rod 4 is arranged on the crushing driving unit 6. The crushing driving unit 6 is used to drive the crushing rod 4 to rotate to break up the water-absorbed and agglomerated compound fertilizer.

[0036] The advantage of setting up the crushing drive unit 6 is that, during the screening process of the vibrating screen, the crushing rod 4 can be used to preliminarily break up the compound fertilizer that has absorbed water and condensed. The design of the crushing rod 4 enables the compound fertilizer that has absorbed water and condensed into blocks to be effectively broken up before entering the vibrating screen, which reduces the probability of the agglomerated fertilizer being blocked on the screen, thereby improving the permeability and screening efficiency of the screen. At the same time, after the crushing rod 4 is used for preliminarily breaking up, the particle size distribution of the compound fertilizer is more uniform, which is conducive to precise control in the subsequent screening process. This can ensure that the screened fertilizer meets the specific particle size requirements and improve product quality.

[0037] The cleaning drive assembly 9 is arranged on the material guide bin 3, and the cleaning ball 5 is arranged on the cleaning drive assembly 9. The cleaning drive assembly 9 is used to drive the cleaning ball 5 to cyclically knock on the vibrating screen surface.

[0038] The advantage of the cleaning drive assembly 9 is that it can avoid clogging of the screen by controlling the cleaning ball 5 to cyclically knock on the screen when screening compound fertilizer. The cyclic knocking of the cleaning ball 5 can effectively remove the blockage on the screen and ensure that the screen remains unobstructed, thereby improving the screening efficiency. The unobstructed flow of the screen allows the material to pass through the screen more smoothly, reducing the residence time of the material on the screen, further improving the screening efficiency. Not only that, the unobstructed flow of the screen can also ensure that the material is fully screened and remove oversized or undersized particles, thereby ensuring the particle size consistency and quality stability of the final product, and the automated and continuous knocking cleaning method can improve the stability and reliability of the production line and reduce downtime and production losses caused by screen blockage.

[0039] The crushing driving unit 6 includes a crushing member 7 arranged in the material guide bin 3, and the crushing member 7 is used to drive the crushing rod 4 to rotate. The crushing member 7 is provided with an angle control member 8, and the angle control member 8 is used to change the contact surface between the crushing rod 4 and the agglomerated compound fertilizer.

[0040] The crushing member 7 includes a power shaft 71 rotatably arranged on the lower material bin 2, and a section of the power shaft 71 extends into the material guide bin 3. A driving motor 72 is arranged on the lower material bin 2, and the power output end of the driving motor 72 is connected to the power shaft 71. The power shaft 71 is located in the material guide bin 3 and one end is rotatably arranged with a rotating tube 73. The power shaft 71 is located in the rotating tube 73 and one end is provided with a torsion spring 74, and the torsion spring 74 is connected to the rotating tube 73. A connecting rod 75 is rotatably arranged on the rotating tube 73, and the connecting rod 75 is connected to the crushing rod 4. A connecting ring 76 is arranged on the crushing rod 4. The crushing rod 4 is rotatably connected to the connecting ring 76, and the connecting ring 76 is slidably connected to the side wall of the material guide bin 3.

[0041] The advantage of setting the crushing member 7 is that the crushing rod 4 can be used to preliminarily break up the compound fertilizer that has absorbed water and condensed. The design of the crushing rod 4 allows the compound fertilizer that has absorbed water and condensed into blocks to be effectively broken up before entering the vibrating screen, which reduces the probability of the agglomerated fertilizer clogging the screen.

[0042] The angle control member 8 includes an annular plate 81 arranged on the power shaft 71, and a plurality of tooth grooves 82 are opened on the annular plate 81. A plurality of rotating gears 83 engaging with the tooth grooves 82 are arranged on the connecting rod 75, and a protective shell is arranged on the rotating tube 73 at the position of the rotating gear 83, and the protective shell can prevent fertilizer particles from interfering with the rotation of the rotating gear 83.

[0043] The advantage of setting the angle control member 8 is that when the staff observes that there are many lumps in the compound fertilizer, the speed of the driving motor 72 is increased to deflect the breaking rod 4, and the contact surface between the triangular breaking rod 4 and the compound fertilizer is converted from a plane to an angular edge. The contact area between the angular edge and the compound fertilizer particles is relatively small, but the pressure is more concentrated, which helps to break the lumps more effectively. Compared with the plane contact, the angular edge can more effectively cut into the inside of the lump, thereby accelerating the crushing process. At the same time, the design of the angular edge helps to form more shearing and extrusion effects during the crushing process, which can enhance the crushing effect and make the compound fertilizer particles looser. When there are fewer lumps in the compound fertilizer, the contact surface between the breaking rod 4 and the compound fertilizer will be changed back to a plane. Compared with the angular edge contact, the plane contact has a more uniform pressure distribution on the material. The uniform pressure distribution helps to reduce the damage of the compound fertilizer particles during the breaking process and maintain the integrity of the particles.

[0044] When the feeding device 1 conveys compound fertilizer to the lower silo 2, the staff first starts the drive motor 72, and the drive motor 72 drives the power shaft 71 to rotate. While the power shaft 71 rotates, the rotating tube 73 connected to it is driven to rotate through the torsion spring 74. The rotation of the rotating tube 73 drives the connecting rod 75 arranged thereon and the crushing rod 4 connected to the connecting rod 75 to rotate. When there are many condensed lumps in the compound fertilizer, the staff adjusts the speed of the drive motor 72 to make the speed of the power shaft 71 faster. At this time, the rotating tube 73 and the power shaft 71 are relatively deflected under the obstruction of inertia and compound fertilizer, so that the annular plate 81 on the power shaft 71 deflects synchronously. The deflection of the annular plate 81 drives the tooth groove 82 thereon to deflect. The deflection of the tooth groove 82 drives the rotating gear 83 engaged with it to rotate. The rotation of the rotating gear 83 drives the connecting rod 75 and the crushing rod 4 to rotate, thereby changing the contact surface between the crushing rod 4 and the compound fertilizer.

[0045] The cleaning drive assembly 9 includes a knocking drive member 10 arranged on the lower material bin 2, and the knocking drive member 10 is used to pop out and recover the cleaning ball 5. The material guide bin 3 is provided with a power member 11, and the power member 11 is used to provide power for the knocking drive member 10 to work. The material guide bin 3 is provided with a release member 12, and the release member 12 is used to control the knocking drive member 10 to release the cleaning ball 5. The release member 12 is provided with a locking member 13, and the locking member 13 is used to lock the release member 12.

[0046] The knocking drive member 10 includes a receiving bin 101 opened in the material guide bin 3, a bottom plate 102 is provided in the receiving bin 101, a rotating shaft 103 is rotatably provided on the bottom plate 102, a winding wheel 104 is provided on the rotating shaft 103, a limiting tube 105 is provided in the receiving bin 101, a traction rope 106 is provided on the winding wheel 104, the traction rope 106 is an elastic rope, a pushing plate 107 is slidably provided in the limiting tube 105, a pushing spring 108 is provided in the limiting tube 105, one end of the pushing spring 108 is connected to the pushing plate 107, the traction rope 106 passes through the limiting tube 105 and the pushing plate 107 and is connected to the cleaning ball 5, the traction rope 106 is an elastic rope, and the traction rope 106 is movably connected to the limiting tube 105 and the pushing plate 107.

[0047] The advantage of setting the knocking drive member 10 is that it can avoid clogging of the screen by controlling the cleaning ball 5 to cyclically knock on the screen when screening compound fertilizer. The cyclic knocking of the cleaning ball 5 can effectively remove the blockage on the screen and ensure that the screen remains unobstructed, thereby improving the screening efficiency.

[0048] The power member 11 includes an annular groove 111 opened on the receiving bin 101, the annular groove 111 is communicated with the receiving bin 101, a plurality of power latch teeth 112 are arranged on the connecting ring 76, the power latch teeth 112 are slidably connected with the annular groove 111, a plurality of driving shafts 113 are rotatably arranged in the receiving bin 101, a power gear 114 engaged with the power latch teeth 112 is arranged on the driving shaft 113, the power gear 114 is slidably connected with the annular groove 111, a transmission gear 1 115 is arranged on the driving shaft 113, and a transmission gear 2 116 engaged with the transmission gear 1 115 is slidably arranged on the rotating shaft 103.

[0049] The advantage of the power member 11 is that the power of the driving motor 72 to drive the crushing rod 4 to rotate can be used to drive the recovery and removal of the cleaning ball 5, thereby saving production costs.

[0050] The release member 12 includes a sliding groove 121 opened on the limiting tube 105, an unlocking plate 122 is provided on the pushing plate 107, and the unlocking plate 122 is slidably connected with the sliding groove 121, a vertical rod 123 is provided in the receiving bin 101, and the vertical rod 123 runs through the receiving bin 101, and an extrusion block 124 is provided on the vertical rod 123, and a traction tube 125 is provided on the transmission gear 2 116, and a round table 126 used in conjunction with the extrusion block 124 is provided on the traction tube 125, and the round table 126 is slidably connected with the rotating shaft 103, and a fixing plate 127 is provided on the rotating shaft 103 at a section located in the traction tube 125, and an extrusion spring 128 is provided on the fixing plate 127, and an extrusion plate 129 is slidably provided on the rotating shaft 103, and the extrusion plate 129 is connected to the extrusion spring 128, and the extrusion plate 129 is in contact with the transmission gear 2 116.

[0051] The advantage of the release member 12 is that the cleaning ball 5 can be controlled to cyclically strike the screen, thereby improving the cleaning effect of the vibrating screen.

[0052] The locking member 13 includes a through slot 131 provided on the vertical rod 123, a locking block 132 is slidably provided in the through slot 131, the locking block 132 is slidably connected to the vertical rod 123, an inclined slot 133 is provided on the locking block 132, a sliding rod 134 is slidably provided in the inclined slot 133, a linkage rod 135 is provided on the sliding rod 134, a pressing slot 136 is provided on the vertical rod 123, the pressing slot 136 is communicated with the through slot 131, a pressing plate 137 is slidably provided in the through slot 131, the pressing plate 137 is slidably connected to the pressing slot 136 and the through slot 131, the pressing plate 137 is connected to the linkage rod 135, a buffer spring 138 is provided in the through slot 131, the buffer spring 138 is connected to the pressing plate 137, and a locking slot 139 used in conjunction with the locking block 132 is provided on the extrusion block 124.

[0053] When the breaker rod 4 rotates, it drives the connecting ring 76 to rotate. The rotation of the connecting ring 76 drives the power latch 112 arranged thereon to rotate. The rotation of the power latch 112 drives the power gear 114 engaged therewith to rotate. The rotation of the power gear 114 drives the driving shaft 113 to rotate synchronously. The rotation of the driving shaft 113 drives the transmission gear 1 115 located thereon to rotate. The rotation of the transmission gear 1 115 drives the transmission gear 2 116 engaged therewith to rotate. The rotation of the transmission gear 2 116 drives the rotating shaft 103 to rotate. The rotation of the rotating shaft 103 drives the winding wheel 104 to rotate. The winding wheel 104 rotates to reel the traction rope 106. During the reeling process of the traction rope 106, the cleaning ball 5 connected thereto is driven to rise and enter the limiting tube 105.

[0054] When the cleaning ball 5 reaches the highest point, the locking groove 139 on the extrusion block 124 engages with the locking block 132 to fix the extrusion block 124. At the same time, the extrusion block 124 squeezes the round table 126, thereby driving the traction tube 125 and the transmission gear 2 116 connected to the traction tube 125 out of engagement with the transmission gear 1 115. At this time, the cleaning ball 5 is quickly ejected from the limiting tube 105 under the push of the pushing plate 107 and the pushing spring 108, and collides with the screen of the vibrating screen, thereby generating vibration to clean the screen and prevent the screen from being blocked.

[0055] When the unlocking plate 122 drops to the lowest point, the pressing plate 137 is squeezed, causing the pressing plate 137 to drop and drive the linkage rod 135 to drop. The linkage rod 135 drops and drives the sliding rod 134 to slide in the inclined groove 133, thereby pushing the locking block 132 to move and disengage from the locking groove 139. At this time, the transmission gear 2 116 is re-engaged with the transmission gear 1 115 under the action of the squeezing spring 128 and the squeezing plate 129, and the squeezing block 124 slides back to the bottom of the vertical pole 123 under the action of gravity. At this time, the winding wheel 104 rotates again to recover the traction rope 106 and the cleaning ball 5.

[0056] When in use, when the feeding device 1 conveys compound fertilizer to the lower silo 2, the staff first starts the drive motor 72, and the drive motor 72 drives the power shaft 71 to rotate. While the power shaft 71 rotates, the rotating tube 73 connected to it is driven to rotate through the torsion spring 74. The rotation of the rotating tube 73 drives the connecting rod 75 arranged thereon and the crushing rod 4 connected to the connecting rod 75 to rotate. When there are many condensed lumps in the compound fertilizer, the staff adjusts the speed of the drive motor 72 to make the speed of the power shaft 71 faster. At this time, under the obstruction of inertia and compound fertilizer, the rotating tube 73 and the power shaft 71 are relatively deflected, so that the annular plate 81 located on the power shaft 71 deflects synchronously. The deflection of the annular plate 81 drives the tooth groove 82 located thereon to deflect. The deflection of the tooth groove 82 drives the rotating gear 83 engaged with it to rotate, and the rotation of the rotating gear 83 drives the connecting rod 75 and the crushing rod 4 to rotate, thereby changing the contact surface between the crushing rod 4 and the compound fertilizer.

[0057] When the breaker rod 4 rotates, it drives the connecting ring 76 to rotate. The rotation of the connecting ring 76 drives the power latch 112 arranged thereon to rotate. The rotation of the power latch 112 drives the power gear 114 engaged therewith to rotate. The rotation of the power gear 114 drives the driving shaft 113 to rotate synchronously. The rotation of the driving shaft 113 drives the transmission gear 1 115 located thereon to rotate. The rotation of the transmission gear 1 115 drives the transmission gear 2 116 engaged therewith to rotate. The rotation of the transmission gear 2 116 drives the rotating shaft 103 to rotate. The rotation of the rotating shaft 103 drives the winding wheel 104 to rotate. The winding wheel 104 rotates to reel the traction rope 106. During the reeling process of the traction rope 106, the cleaning ball 5 connected thereto is driven to rise and enter the limiting tube 105.

[0058] When the cleaning ball 5 reaches the highest point, the locking groove 139 on the extrusion block 124 engages with the locking block 132 to fix the extrusion block 124. At the same time, the extrusion block 124 squeezes the round table 126, thereby driving the traction tube 125 and the transmission gear 2 116 connected to the traction tube 125 out of engagement with the transmission gear 1 115. At this time, the cleaning ball 5 is quickly ejected from the limiting tube 105 under the push of the pushing plate 107 and the pushing spring 108, and collides with the screen of the vibrating screen, thereby generating vibration to clean the screen and prevent the screen from being blocked.

[0059] When the unlocking plate 122 drops to the lowest point, the pressing plate 137 is squeezed, causing the pressing plate 137 to drop and drive the linkage rod 135 to drop. The linkage rod 135 drops and drives the sliding rod 134 to slide in the inclined groove 133, thereby pushing the locking block 132 to move and disengage from the locking groove 139. At this time, the transmission gear 2 116 is re-engaged with the transmission gear 1 115 under the action of the squeezing spring 128 and the squeezing plate 129, and the squeezing block 124 slides back to the bottom of the vertical pole 123 under the action of gravity.
