Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production pulverizing equipment, in particular to a rolling fertilizer uniform pulverizing mechanism for agricultural fertilizer production. Background Art

[0002] Agricultural fertilizers refer to substances used in the agricultural production process to improve soil properties and increase soil fertility levels. They are mainly divided into compound fertilizers, organic fertilizers, microbial fertilizers and slow-release fertilizers. These fertilizers can provide crops with the necessary elements for growth, improve crop photosynthesis, increase crop yield and quality, and enhance crop resistance to cold, drought, disease and lodging.

[0003] In the prior art, such as Chinese patent publication number CN113976246A, a rolling fertilizer uniform crushing mechanism for agricultural fertilizer production is disclosed, which relates to the technical field of agricultural fertilizer production, including a device body, a feed port is opened on the top of the device body, and an observation window is installed on the outer surface of the device body. The invention is provided with a cleaning component. When the user needs to clean the screening net, the user slides the slide plate to drive the second connecting plate and the cleaning brush to move. When the cleaning brush moves, the bottom contacts the screening net and the fine fertilizer attached to the screening net is brushed off. When the cleaning brush moves, it will also drive the large fertilizers blocked on the screening net to move synchronously. The fertilizers will be driven by the cleaning brush to the cleaning inclined plate and fall to the outside of the machine. Then, the fertilizers that do not meet the crushing standards are poured back into the machine for secondary crushing, and the fertilizers that do not meet the crushing standards are prevented from being blocked on the screening net, and the working efficiency of the machine is improved.

[0004] Although the above patents prevent fertilizers that do not meet the crushing standards from clogging the screening net, the existing rolling fertilizer crushing devices for agricultural fertilizer production have the following shortcomings during use: 1. There are many types of raw materials for agricultural fertilizers, among which raw materials such as phosphate rock and peat blocks are in block form and have different sizes. Agricultural fertilizer raw materials with a volume much larger than the spacing between the rolling channels are difficult to pass directly after falling into the rolling crushing device, resulting in a decrease in crushing efficiency; 2. During the production process of agricultural fertilizers, when crushing its raw materials, the phosphate rock and potassium feldspar types of raw materials have a high hardness, and it is difficult to effectively crush them after entering the rolling crushing device, and even damage to the crushing roller and equipment failure may be caused; 3. Existing agricultural fertilizer rolling crushing devices usually have multiple groups of crushing mechanisms to crush the raw materials multiple times to ensure the uniformity of crushing, but the lower crushing component will crush all the upper crushed materials again each time, and it is impossible to remove the crushed materials with qualified particle size in advance, which directly causes unnecessary burden on the lower crushing component.

[0005] Therefore, a rolling fertilizer uniform crushing mechanism for agricultural fertilizer production is proposed to solve the problems raised in the above background technology. Summary of the invention

[0011] Preferably, the V-shaped plate is arranged above the two sieve plates, and the two sieve plates are symmetrically inclined. The V-shaped plate and the front and rear outer surfaces of the two sieve plates are fixedly connected by connecting strips through axial symmetry. The connecting strips are slidably arranged inside the second avoidance groove, and the length of the connecting strips is smaller than the length of the second avoidance groove. A connecting plate is fixedly connected between the outer surfaces of the connecting strips on the same side, and a third connecting shaft is fixedly connected at the center of the outer surfaces of the opposite sides of the two connecting plates.

[0016] Preferably, a group of bristles are disposed on the outer surfaces of the two additional rollers, the bristles and the impact columns are arranged in a staggered manner, and the outer surfaces of the bristles are in contact with the outer surface of the fine grinding roller.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, after the raw materials are put into the vertical processing shell, the large-volume raw materials will be stuck in the gap between the solid steel plate and the coarse grinding roller, the driving motor is started, and the coarse grinding roller is driven to move eccentrically via the crankshaft and the eccentric block. During the eccentric movement of the coarse grinding roller, it constantly approaches and moves away from the solid steel plate on the side, thereby achieving the purpose of impacting the large-volume raw materials. Moreover, due to the meshing of the first gear and the inner gear ring, the coarse grinding roller continues to rotate during the impact process. The rotating coarse grinding roller can use friction to crush the raw materials. The design of impact combined with crushing and kneading can quickly crush the large-volume raw materials into small pieces, thereby solving the problem of low crushing efficiency due to the inability of large-volume raw materials to directly pass through the subsequent crushing channel.

[0018] 2. When the present invention is used, when the fertilizer contains high-hardness materials, the two fine grinding rollers will be subjected to a large reverse thrust during the rolling process. When the reverse thrust is greater than the tension provided by the tension spring, the two fine grinding rollers will rotate outward with the first pulley as the center, thereby generating a larger gap to allow the high-hardness materials to pass through, and then automatically reset under the action of the tension spring. During the process, the first pulley on the mounting plate cooperates with the transmission belt and the second pulley to continuously provide driving force for the fine grinding rollers. This design effectively solves the problem that high-hardness materials in agricultural fertilizer raw materials are prone to damage the fine grinding rollers and even cause equipment failures, thereby increasing the service life of the equipment.

[0019] 3. When the present invention is used, the driving motor is turned to rotate the crankshaft, and its crank neck drives the eccentric movement of the upper end of the connecting rod, and the lower end allows the connecting plate to reciprocate up and down through the third connecting shaft, thereby causing the V-shaped plate and the screen plate to bump, and the raw materials after coarse grinding fall on the V-shaped plate, slide to the outside of the screen plate and then slide to the middle. During this period, small-size raw materials directly fall and are pre-removed without entering the fine grinding component. Large-volume raw materials fall between the two fine grinding rollers and are crushed again. This design effectively improves the uniformity of grinding, reduces the burden on the fine grinding component, significantly improves the overall grinding efficiency, and optimizes the grinding process in agricultural fertilizer production.

[0020] 4. When the present invention is used, the coarse grinding component, pre-separation component, fine grinding component and auxiliary component only need one driving motor to provide driving force, which reduces the device cost and energy consumption, and has the effect of energy saving and emission reduction.

DETAILED DESCRIPTION

[0023] 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 implementation regulations described 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.

[0024] Example 1: Please refer to Figure 1-Figure 9 As shown, the present invention provides a technical solution: a rolling fertilizer uniform crushing mechanism for agricultural fertilizer production, comprising a shell component 1, wherein a coarse grinding component 2, a pre-separation component 3, a fine grinding component 4 and an auxiliary component 5 are arranged near the top of the shell component 1, and the shell component 1 comprises a vertical processing shell 101, and the front and rear inner surface walls of the vertical processing shell 101 are fixedly connected to a solid steel plate 105 near the top, and the outer surfaces of both sides of the vertical processing shell 101 are fixedly connected to a protective shell 109, and a driving motor 113 is installed near the top of the outer surface of one of the protective shells 109, and the outer surface of the other protective shell 109 is rotatably connected to a first pulley 1 10 and the second pulley 111, a transmission belt 112 is arranged between the outer surfaces of the first pulley 110 and the second pulley 111, a slag discharge port 102 is opened near the bottom of the front surface of the vertical processing shell 101, the coarse grinding component 2 includes a coarse grinding roller 208 and two convex shells 201, the pre-separation component 3 is arranged below the coarse grinding component 2, and is used for pre-screening qualified crushed materials, including a V-shaped plate 301 and two screen plates 302, the fine grinding component 4 is arranged below the pre-separation component 3, and is used for secondary crushing of fertilizer raw materials, including two fine grinding rollers 401 and two sets of mounting plates 404, and the auxiliary component 5 is arranged below the fine grinding component 4, including two additional rollers 501.

[0025] The outer surfaces of the opposite sides of the two solid steel plates 105 are provided with arc surfaces 106 near the bottom, the solid steel plates 105 and the coarse grinding roller 208 cooperate with each other, a collecting box 104 is installed near the bottom of the outer surface of one side of the vertical processing shell 101, and the outer surfaces of both sides of the vertical processing shell 101 are symmetrically provided with second avoidance grooves 108 near the middle, and the outer surfaces of both sides of the vertical processing shell 101 are symmetrically provided with first avoidance grooves 107 below the second avoidance grooves 108. An inclined screen 103 is fixedly connected between the inner surface walls of the vertical processing shell 101 near the bottom, and the front surface of the screen 103 and the slag discharge The positions of the openings 102 correspond to each other. The solid steel plate 105 has high strength and can maintain good structural stability after being impacted and is not easily deformed. The collecting box 104 is mainly used to collect agricultural fertilizers with qualified particle sizes. The design of the second avoidance groove 108 allows the pre-separation component 3 to move up and down within a certain stroke. The design of the first avoidance groove 107 allows the fine grinding roller 401 to move within a certain stroke. The second avoidance groove 108 is arc-shaped and takes the second gear 410 on the same side as the center of rotation. The screen 103 is used to screen the broken materials. The broken materials larger than the aperture of the screen 103 will be discharged from the slag discharge port 102 under the action of gravity.

[0026] The two convex shells 201 are symmetrically fixedly connected to the outer surfaces of both sides of the vertical processing shell 101, and the two ends of the coarse grinding roller 208 are fixedly connected with the second connecting shaft 206. The outer surface of the convex shell 201 is rotatably connected with the crankshaft 202. The opposite ends of the two crankshafts 202 rotate through the convex shell 201 and are fixedly connected with the eccentric block 204. The second connecting shaft 206 and the outer surface of the eccentric block 204 are rotatably connected near the edge. The convex shell 201 is convex outward. When the crankshaft 202 rotates, the eccentric block 204 can be mobilized to rotate. Under the action of the eccentric block 204, the second connecting shaft 206 can drive the coarse grinding roller 208 to perform a circular motion with the inner end of the crankshaft 202 as the center.

[0027] The outer surface of the second connecting shaft 206 is fixedly connected with the first gear 207, the inner surface wall of the outer convex shell 201 is fixedly connected with the inner gear ring 205, the outer surface of the first gear 207 is meshed with the inner surface wall of the inner gear ring 205, the outer surface of the crankshaft 202 is rotatably connected with the connecting rod 203 near the middle crank neck, the opposite ends of the two crankshafts 202 are rotated to penetrate the outer surface of the protective shell 109, the first pulley 110 is fixedly connected to one of the crankshafts 202 through the shaft, and the output end of the drive motor 113 and Another crankshaft 202 is fixedly connected, the inner gear ring 205 is fixedly connected to the inner wall of the outer convex shell 201, and is arranged coaxially with the driving shaft of the driving motor 113. During the rotation of the first gear 207, it will always be in a meshing state with the inner wall of the inner gear ring 205. Therefore, when the first gear 207 follows the movement of the second connecting shaft 206, it will drive the coarse grinding roller 208 to rotate. The friction force generated by the self-rotating coarse grinding roller 208 when hitting the large piece of raw material can produce a certain grinding effect on the surface layer of the raw material.

[0028] The use steps of the present invention are as follows: when the device is used to crush raw materials during agricultural fertilizer production, the fertilizer raw materials are put in from the upper opening of the vertical processing shell 101, and the raw materials with larger volumes will be retained in the gap between the solid steel plate 105 and the coarse grinding roller 208. After the drive motor 113 is started, the drive motor 113 drives the eccentric block 204 on the inner side of the outer convex shell 201 to rotate through the crankshaft 202. When the eccentric block 204 rotates, it drives the coarse grinding roller 208 to perform eccentric movement through the second connecting shaft 206. When the coarse grinding roller 208 performs eccentric movement between the two solid steel plates 105, the coarse grinding roller 208 will continuously approach the solid steel plates 105 away from the front and rear sides. Thereby forming a collision. At the same time, when the coarse grinding roller 208 performs eccentric movement under the action of the eccentric block 204, the surface of the first gear 207 on the surface of the second connecting shaft 206 is meshed with the inner gear ring 205 on the inner wall of the outer convex shell 201. Therefore, during the circular motion of the first gear 207, the coarse grinding roller 208 will be driven to rotate through the second connecting shaft 206. Therefore, when a large volume of raw materials put into the vertical processing shell 101 are retained between the solid steel plate 105 and the coarse grinding roller 208, the coarse grinding roller 208 will continue to rotate and move left and right at the same time, thereby forming an impact with the large volume of raw materials, so that they are quickly broken into small pieces of raw materials, thereby improving the subsequent crushing efficiency.

[0029] Embodiment 2: Figure 2 and Figure 5As shown, the difference between the embodiment and the base is that the V-shaped plate 301 is arranged above the two sieve plates 302, and the two sieve plates 302 are symmetrically inclined. The front and rear outer surfaces of the V-shaped plate 301 and the two sieve plates 302 are fixedly connected by a connecting strip 303 through an axisymmetric, and the connecting strip 303 is slidably arranged inside the second avoidance groove 108, and the length of the connecting strip 303 is less than the length of the second avoidance groove 108. A connecting plate 304 is fixedly connected between the outer surfaces of the connecting strips 303 on the same side, and a third connecting shaft 305 is fixedly connected at the center of the outer surfaces of the opposite sides of the two connecting plates 304. The third connecting shaft 305 and the connecting rod 203 are fixedly connected. The bottom end is rotatably connected, and when the crankshaft 202 rotates, the connecting plate 304 is driven to reciprocate up and down through the connecting rod 203 and the third connecting shaft 305, which will synchronously drive the sieve plate 302 and the V-shaped plate 301 to move. When the sieve plate 302 and the V-shaped plate 301 move, the connecting strip 303 cooperates with the second avoidance groove 108 on the surface of the vertical processing shell 101 to limit the moving path of the sieve plate 302 and the V-shaped plate 301, and the size of the connecting strip 303 is smaller than the size of the second avoidance groove 108. Therefore, when the connecting strip 303 moves up and down, the second avoidance groove 108 is always in a closed state, which can prevent the dusty fertilizer raw materials from escaping.

[0030] The use steps of the present invention are as follows: when the driving motor 113 drives the crankshaft 202 to rotate, the curved neck on the surface of the crankshaft 202 drives the upper end of the connecting rod 203 to perform eccentric motion with the output end of the driving motor 113 as the center. At this time, the bottom end of the connecting rod 203 drives the connecting plate 304 to perform up and down reciprocating motion through the third connecting shaft 305. During the up and down reciprocating motion of the connecting plate 304, the V-shaped plate 301 and the screen plate 302 are synchronously driven to bump up and down. The agricultural fertilizer raw materials crushed by the coarse grinding component 2 are crushed by gravity. The raw materials with smaller particle sizes will fall directly downward to complete the early removal operation without passing through the fine grinding component 4 below, while the raw materials with unqualified volume will fall from the middle position of the two sieve plates 302 to between the two fine grinding rollers 401 for further crushing, which improves the crushing uniformity while reducing the workload of the fine grinding component 4 and improves the overall crushing efficiency.

[0031] Embodiment 3: Figure 2 and Figure 6-Figure 9As shown, the difference between the embodiment and the embodiment is that the front and rear ends of the two fine grinding rollers 401 are fixedly connected to the fourth connecting shaft 402, and the outer surface of the fourth connecting shaft 402 is rotatably connected to the arc block 403, and the arc block 403 is slidably arranged inside the first avoidance groove 107. The length of the first avoidance groove 107 is greater than the length of the arc block 403. When the fine grinding roller 401 moves, the fourth connecting shaft 402 will drive the arc block 403 inside the first avoidance groove 107 to move synchronously, and the arc The length of the arc block 403 is smaller than that of the first avoidance groove 107. Therefore, when the arc block 403 moves with the fine grinding roller 401, the first avoidance groove 107 is moderately in a closed state, which can effectively prevent the dusty fertilizer raw materials from escaping. The surfaces of the two fine grinding rollers 401 are provided with staggered grooves, and the groove depth and width match the aperture of the sieve plate 302, which are used to limit the particle size of the agricultural fertilizer after crushing, avoid the crushed material being too small to affect the use, and at the same time make the fertilizer after screening by the sieve plate 302 meet the maximum particle size range of the fertilizer.

[0032] The mounting plates 404 are grouped in pairs and adjacent mounting plates 404 are symmetrically arranged, the outer surface of the mounting plates 404 is rotatably connected to a first pulley 407 near the bottom, the outer surface of the mounting plates 404 is rotatably connected to a second pulley 408 near the top, a transmission belt 409 is arranged between the outer surfaces of the first pulley 407 and the second pulley 408, the outer surface of the second pulley 408 is fixedly connected to the end of the fourth connecting shaft 402, the outer surface of the fourth connecting shaft 402 rotates and passes through the outer surface of the mounting plate 404, the mounting plate 404 is mainly used to install the first pulley 407, the second pulley 408 and the transmission belt 409, and the rotation center of the mounting plate 404 is consistent with the center of the first pulley 407, and can rotate outward, when the first pulley 407 rotates, the second pulley 408 can be driven to rotate through the transmission belt 409, and the fine grinding roller 401 is further driven to rotate through the fourth connecting shaft 402.

[0033] The outer surface of the mounting plate 404 is fixedly connected to a hook column 405, and a tension spring 406 is installed between the outer surfaces of adjacent hook columns 405. The outer surface of the mounting plate 404 near the bottom is rotatably connected to the outer surface of the vertical processing shell 101, and the outer surface of the first pulley 407 is fixedly connected to a second gear 410, and the outer surfaces of adjacent second gears 410 are meshed and connected, and the outer surface of one of the second gears 410 is fixedly connected to a fifth connecting shaft 411, and the outer surface of the fifth connecting shaft 411 rotates through the outer surface of the protective shell 109 and the end of the fifth connecting shaft 411 is connected to the second belt pulley. The wheel 111 is fixedly connected, and the tension generated by the tension spring 406 and the hook column 405 mainly acts on two adjacent mounting plates 404, so that the adjacent mounting plates 404 are close to each other, and the adjacent second gears 410 are meshed with each other. Therefore, when one of the second gears 410 rotates, the two second gears 410 will drive the first pulley 407 connected thereto to rotate synchronously in the opposite direction, thereby making the two fine grinding rollers 401 rotate synchronously inward to roll and crush the fertilizer raw materials. The second pulley 111 can transmit the rotational force to one of the second gears 410 through the fifth connecting shaft 411.

[0034] A group of impact columns 502 are arranged and fixedly connected on the outer surfaces of the two additional rollers 501, and the two groups of impact columns 502 are staggered. The additional rollers 501 are rotatably connected between the inner walls on both sides of the vertical processing shell 101 through an axis, and the two ends of the additional rollers 501 are fixedly connected through an axis and a first pulley 407. The additional rollers 501 are connected to the first pulley 407 through an axis, and the axis rotates through the mounting plate 404. When the first pulley 407 rotates, it will synchronously drive the two additional rollers 501 to rotate in the opposite direction. At this time, the staggered impact columns 502 on the surface of the additional rollers 501 can quickly and frequently hit and crush the crushed fertilizer, further improving the uniformity of the crushing.

[0035] The outer surface of the two additional rollers 501 is provided with a group of bristles 503. The bristles 503 and the impact columns 502 are arranged in an alternating manner. The outer surface of the bristles 503 fits the outer surface of the fine grinding roller 401. When the additional rollers 501 rotate, the bristles 503 on the surface will be in a straight state and rotate with the action of centrifugal force. In this process, the bristles 503 can provide a cleaning effect on the fine grinding roller 401, so that the fertilizer adhered to its surface falls to the bottom for collection, thereby improving the use effect.

[0036] The use steps of the present invention are as follows: the small pieces of fertilizer raw materials remaining after passing through the pre-separation component 3 will fall from the position above the middle of the two fine grinding rollers 401. At the same time, the crankshaft 202 in the coarse grinding component 2 will drive the second pulley 111 below to rotate through the first pulley 110 and the transmission belt 112 during the rotation process. When the second pulley 111 rotates, it will drive one of the second gears 410 to rotate through the fifth connecting shaft 411. The two second gears 410 on the same side of the device are in a meshing state. Therefore, when the second gear 410 rotates, it will drive the first pulley 407 on the surface of the mounting plate 404 to rotate synchronously in the opposite direction. Subsequently, the transmission belt 409, the second pulley 408 and the fourth connecting shaft 402 cooperate to achieve the purpose of driving the two fine grinding rollers 401 to rotate synchronously in the opposite direction. When the small pieces of fertilizer raw materials pass through the two fine grinding rollers 401, they will be crushed into small granular fertilizers and fall downward. During the falling process, the first pulley 40 The synchronously rotating additional rollers 501 will drive the staggered impact columns 502 to impact the fallen small-particle fertilizer at high speed, so as to avoid the fertilizer from sticking due to squeezing, and effectively improve the uniformity after crushing. When the fertilizer contains high-hardness materials, the two fine grinding rollers 401 will be subjected to a large reverse thrust during the crushing process. When the reverse thrust is greater than the tension provided by the tension spring 406, the two fine grinding rollers 401 will rotate outward with the first pulley 407 as the center, thereby generating a larger gap to allow the high-hardness materials to pass through, and then automatically reset under the action of the tension spring 406. This design effectively solves the problem that the high-hardness materials in the agricultural fertilizer raw materials are easy to damage the fine grinding rollers 401 and even cause equipment failure, thereby improving the service life of the equipment. When the fertilizer is crushed and crushed, it falls downward, and the materials that meet the standard volume will pass through the aperture of the screen 103 and fall into the collection box 104 for collection, and the materials that do not meet the standard will be discharged from the slag discharge port 102 under the action of gravity.
