Description

Technical Field

[0001] This application relates to the technical field of fertilizer conveying equipment, specifically to an anti-caking conveying device for fertilizer feeders. Background Technology

[0002] Fertilizer agglomeration is a common and challenging problem in fertilizer production and transportation. Existing fertilizer feeding machines have several shortcomings in addressing this issue. Firstly, many machines have a fixed extrusion structure height, making it impossible to adjust to variations in fertilizer packaging sizes. This makes it difficult to effectively break up and prevent agglomeration of fertilizer packages that are too large or too small, affecting normal transportation and use. Secondly, traditional machines often use a single extrusion plate to compress the fertilizer. While this method can break up agglomerates to some extent, the large contact area results in a low unit contact force, leading to poor breaking up of larger internal clumps and insufficient movement of the fertilizer within the packaging, resulting in limited overall agglomeration. Furthermore, existing machines often lack effective buffering mechanisms when facing varying resistance caused by different fertilizer agglomerate hardness, making related parts susceptible to damage from excessive stress. This increases equipment maintenance costs and downtime, reducing production efficiency.

[0003] Therefore, there is an urgent need for an anti-caking conveying device for fertilizer feeders that can adapt to different fertilizer packaging specifications, efficiently break up clumps, and has parts protection functions, in order to meet the actual needs of fertilizer production and transportation processes. Summary of the Invention

[0004] To address the aforementioned technical problems, this application solves the problem that existing fertilizer feeding machines, due to their lack of adaptability to fertilizer packaging specifications, unreasonable extrusion and dispersal methods, and lack of buffer protection mechanisms, result in fertilizer clumps that are difficult to effectively disperse and smoothly conveyed, and the equipment is prone to damage.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an anti-caking conveying device for a fertilizer feeding machine, comprising a conveying platform, an adjusting component fixedly mounted on the conveying platform, a protective cover mounted on the adjusting component, a protective plate fixedly mounted on the protective cover, a plurality of first extrusion blocks and second extrusion blocks slidably mounted on the protective plate, each of the first extrusion blocks and second extrusion blocks having a groove, a plurality of connecting blocks fixedly mounted on each groove, a telescopic rod rotatably mounted on the connecting block, a spring sleeved on the telescopic rod, and the two ends of the spring being fixedly connected to the two ends of the telescopic rod.

[0006] To better realize this application, the first extrusion block and the second extrusion block are further disposed in a staggered manner. The first extrusion block is provided with two holes, and a horizontal limiting rod is installed in each hole. The horizontal limiting rod is provided with multiple protrusions, which are respectively inserted into the holes of the multiple first extrusion blocks.

[0007] To better realize this application, two side connecting rods are slidably arranged on the horizontal limiting rod, and a vertical limiting rod is slidably arranged on the side connecting rod. Multiple protrusions are arranged on the vertical limiting rod, and the protrusions are arranged in the groove of the second extrusion block and fixedly connected to the second extrusion block.

[0008] To better realize this application, a power source is further fixedly installed on the protective cover. The power source includes a first motor and a second motor, which are arranged in opposite directions. A drive frame is fixedly installed at the output end of both the first motor and the second motor.

[0009] To better realize this application, the drive frame further includes multiple upper connecting rods and multiple lower connecting rods, with each upper connecting rod fixedly connected to the output end of the power source, and each lower connecting rod simultaneously fixedly connected to the same position of the multiple upper connecting rods.

[0010] To better realize this application, the lower connecting rod is further provided with multiple shafts, and the end of the telescopic rod away from the protective plate is rotatably mounted on the shaft of the lower connecting rod.

[0011] The technical solution provided in this application has the following advantages compared with the prior art:

[0012] 1. This application achieves the function of flexibly adjusting the distance between the first and second extrusion blocks and the conveyor table according to the fertilizer packaging specifications by adjusting the motor and screw drive of the protective cover to move up and down. This enables the device to accurately adapt to fertilizer packaging of different specifications, ensuring that it can effectively break up clumps of fertilizer of various specifications. It overcomes the shortcomings of traditional devices that cannot adapt to changes in fertilizer packaging specifications and improves the versatility and practicality of the device.

[0013] 2. This application employs a design where the first and second extrusion blocks are staggered and move vertically under the control of a telescopic rod. This design ensures that the contact points between the extrusion blocks and the fertilizer are evenly spaced, reducing the contact area between a single extrusion block and the fertilizer, increasing the unit contact force, and enabling rapid breaking up of internal clumps in the fertilizer. Simultaneously, the staggered extrusion promotes movement of the fertilizer within the packaging, comprehensively improving the dispersing effect and solving the problem of unsatisfactory dispersing effect with traditional single-piece extrusion plates, thus ensuring the quality of the fertilizer and its subsequent use.

[0014] 3. This application incorporates a spring on the telescopic rod. When fertilizer clumps of varying hardness cause different levels of resistance at the lower end of the telescopic rod, the spring can buffer this resistance through its own elasticity, while simultaneously using high-frequency vibration to help break up the clumps. This design effectively avoids damage to components caused by excessive resistance, extends the service life of the equipment, reduces maintenance costs, solves the problem of easily damaged components in traditional devices due to the lack of a buffering mechanism, and improves the stability and reliability of the equipment.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] like Figures 1 to 6As shown, the anti-caking conveying device for fertilizer feeding machine includes a conveying platform 101. An adjusting component 103 is fixedly installed on the conveying platform 101. A protective cover 102 is installed on the adjusting component 103. A protective plate 104 is fixedly installed on the protective cover 102. Multiple first extrusion blocks 105 and second extrusion blocks 106 are slidably arranged on the protective plate 104. Both the first extrusion blocks 105 and the second extrusion blocks 106 are provided with grooves. Multiple connecting blocks 110 are fixedly installed on the grooves. A telescopic rod 111 is rotatably arranged on the connecting block 110. A spring 112 is sleeved on the telescopic rod 111. The two ends of the spring 112 are fixedly connected to the two ends of the telescopic rod 111.

[0025] Specifically, the fertilizer, which is broken up by the conveyor belt on the conveyor table 101, is transported to the bottom of the protective cover 102. At the same time, the height of the protective cover 102 is adjusted according to the specifications of the fertilizer packaging. That is, the motor and screw installed in the adjusting component 103 drive the protective cover 102 to move up and down, adjusting the distance between the first extrusion block 105 and the second extrusion block 106 inside the protective cover 102 and the conveyor table 101, so as to avoid the fertilizer being too large or too small, which would prevent it from being broken up and clumping.

[0026] During the dispersing process, the upper ends of different groups of telescopic rods 111 are controlled to move left and right, thereby causing the lower ends of each group of telescopic rods 111 to move the first extrusion block 105 and the second extrusion block 106 up and down. By raising and lowering the first extrusion block 105 and the second extrusion block 106, the fertilizer is brought closer to and squeezed away from the fertilizer. This process is then combined with the extrusion table 101 to squeeze the clumps in the fertilizer packaging. The fertilizer is then broken up by repeated high-frequency extrusion vibrations and then transported out by the extrusion table 101.

[0027] like Figures 2 to 6 As shown, the first extrusion block 105 and the second extrusion block 106 are staggered. The first extrusion block 105 has two holes, and a horizontal limiting rod 107 is installed in each hole. The horizontal limiting rod 107 has multiple protrusions, which are respectively inserted into the holes of the first extrusion block 105.

[0028] Specifically, the first extrusion block 105 and the second extrusion block 106 are alternately arranged. When the telescopic rod 111 controls the movement of the first extrusion block 105 and the second extrusion block 106, they move in an alternating up-and-down manner. That is, the first extrusion block 105 moves downward towards the fertilizer, and the second extrusion block 106 moves upward away from the fertilizer. This ensures that the contact points with the fertilizer are evenly spaced within a uniform time frame. Utilizing this space, the fertilizer's internal clumps are rapidly broken up during the extrusion and dispersal process. This avoids the situation where fertilizer clumps are too large, making it difficult to quickly and effectively break up internal clumps when using a single piece of material for dispersal. In this application, the contact area between a single first extrusion block 105 or second extrusion block 106 and the fertilizer is small, resulting in a greater contact force at the same time and a faster breaking speed. Furthermore, the alternating arrangement causes the fertilizer to move towards each other, thereby promoting the movement of the fertilizer within the packaging and improving the dispersal effect.

[0029] like Figures 2 to 6 As shown, two side connecting rods 108 are slidably arranged on the horizontal limiting rod 107, and a vertical limiting rod 109 is slidably arranged on the side connecting rod 108. Multiple protrusions are arranged on the vertical limiting rod 109, and the protrusions are arranged in the groove of the second extrusion block 106 and fixedly connected to the second extrusion block 106.

[0030] Specifically, the horizontal limiting rods 107 restrict and fix the sides of the multiple first extrusion blocks 105 to prevent displacement during extrusion. The horizontal limiting rods 107 at both ends of the first extrusion blocks 105 are connected by the side connecting rods 108, so that the two horizontal limiting rods 107 and the two side connecting rods 108 form a rectangle, which fits tightly with the multiple first extrusion blocks 105 to restrict and fix the multiple first extrusion blocks 105.

[0031] The second extrusion block 106 is restricted and fixed by the protrusion on the vertical limiting rod 109, and the height of the vertical limiting rod 109 matches the vertical movement distance of the first extrusion block 105 and the second extrusion block 106, so that when the second extrusion block 106 moves downward and the first extrusion block 105 moves upward, the vertical limiting rod 109 is prevented from interfering with the movement of the first extrusion block 105.

[0032] like Figure 2 , Figure 4 and Figure 5 As shown, a power source is fixedly installed on the protective cover 102. The power source includes a first motor 115 and a second motor 116. The first motor 115 and the second motor 116 are arranged in opposite directions. A drive frame is fixedly installed at the output end of both the first motor 115 and the second motor 116.

[0033] Specifically, by setting a first motor 115 and a second motor 116 to control multiple first extrusion blocks 105 and second extrusion blocks 106 respectively, they are made to move up and down alternately to spread fertilizer and prevent caking during transport.

[0034] like Figures 2 to 5 As shown, the drive frame includes multiple upper connecting rods 114 and multiple lower connecting rods 113. The multiple upper connecting rods 114 are fixedly connected to the output end of the power source, and each lower connecting rod 113 is simultaneously fixedly connected to the same position of the multiple upper connecting rods 114.

[0035] Specifically, the output of the first motor 115 controls the upper connecting rod 114 to move laterally on the protective cover 102. The upper connecting rod 114 drives the upper ends of multiple sets of telescopic rods 111 to move laterally through the lower connecting rod 113, thereby pushing the lower ends of the telescopic rods 111 to control the first extrusion block 105 to slide on the protective plate 104, thereby extruding or removing the fertilizer. The second motor 116 similarly controls the second extrusion block 106.

[0036] During use, depending on the different hardness of the clumps at different locations within the fertilizer, the resistance received by the first extrusion block 105 or the second extrusion block 106 varies, resulting in different resistance at the lower end of the telescopic rod 111. This resistance, along with the control of the lower connecting rod 113 over the upper end of the telescopic rod 111, causes the telescopic rod 111 itself to contract and compress the spring 112. The elastic force of the spring 112 buffers this resistance, and the high-frequency vibration disperses the clumps, thereby preventing damage to parts and improving service life.

[0037] like Figures 2 to 5 As shown, the lower connecting rod 113 is provided with multiple shafts, and the end of the telescopic rod 111 away from the protective plate 104 is rotatably mounted on the shaft of the lower connecting rod 113.

[0038] Specifically, multiple springs 112 on the lower connecting rod 113 shaft form a group, and each group is connected to only one of the first pressing block 105 or the second pressing block 106, but not simultaneously to the first pressing block 105 and the second pressing block 106. When the lower connecting rod 113 pushes the upper end of the telescopic rod 111, the upper end of the telescopic rod 111 rotates on the shaft of the lower connecting rod 113, while the lower end of the telescopic rod 111 rotates on the shaft of the connecting block 110, and uses the elastic force of the springs 112 on the telescopic rod 111 to push the connecting block 110, thereby controlling the raising and lowering of the first pressing block 105 or the second pressing block 106.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
