Description

Technical Field

[0001] This utility model relates to the field of conveying machinery technology, specifically to a raw material lifting and conveying device for fertilizer mixing equipment. Background Technology

[0002] In the fertilizer production field, bucket elevators are key equipment for vertical material transport. However, when transporting fertilizers such as compound fertilizers and organic fertilizers that are prone to moisture absorption and clumping, a long-standing technical challenge is that fertilizers spend the most time in contact with the buckets inside the elevator, easily adhering and hardening onto the inner walls of the buckets. This adhesion leads to a continuous reduction in the effective loading volume of the buckets, directly decreasing the elevator's transport efficiency, and manual cleaning is time-consuming and labor-intensive. More seriously, the continuous accumulation of adhered material forms stubborn deposits that are not only difficult to remove but also cause cross-contamination when changing fertilizer types, severely affecting product quality. Existing technologies, such as the solution disclosed in patent CN202322642075.7, employ an anti-sticking mechanism consisting of springs, rubber balls, and pull ropes installed on the outside of the elevator casing. The rubber balls are driven to impact the casing by periodically pulling the ropes manually to clear blockages. However, this solution only cleans the inner walls of the elevator casing and cannot automatically clean each bucket that directly contacts the fertilizer. Therefore, there is an urgent need for a solution that can effectively shake off fertilizer adhering to the inner wall of the hopper from the source, automatically prevent material accumulation, and maintain stable conveying efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a raw material lifting and conveying device for fertilizer mixing equipment, which can effectively shake off the fertilizer adhering to the hopper, prevent material accumulation and maintain stable conveying efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a raw material lifting and conveying device for fertilizer mixing equipment, comprising a lifting machine housing, a driving mechanism, and multiple hoppers driven by the driving mechanism. The lifting and conveying device further comprises multiple impact generating components arranged in a one-to-one correspondence with the hoppers. A guide is provided on the outer wall of the hopper body. The impact generating components are slidably disposed on the guide, wherein the sliding direction of the impact generating components is parallel to the loading and unloading direction of the hopper.

[0005] Preferably, the impact generating component includes a support rod and two limiting nuts; the guide includes two guide plates; the guide plates are laid along the direction from the bottom end of the hopper to the port; the guide plates have waist-shaped holes along their length; the support rod slides through the two waist-shaped holes in sequence, and extends to the outside of the guide plates at both ends; the two limiting nuts are screwed onto the two ends of the support rod and are located on the outside of the guide plates.

[0006] Preferably, the impact generating component further includes a counterweight tube; the counterweight tube is sleeved on the support rod.

[0007] Preferably, the counterweight tube is located between the two guide plates, and the outer diameter of the counterweight tube is greater than the width of the waist-shaped hole.

[0008] Preferably, the counterweight tube and the support rod are slidably connected.

[0009] Preferably, at least one limiting protrusion is fixedly provided on the outer wall of the hopper. The limiting protrusion is located on the sliding path of the impact generating component and is used to delay its sliding to enhance the impact effect.

[0010] Preferably, there are two limiting protrusions, and the distance between the two limiting protrusions is less than the length of the waist-shaped hole.

[0011] Preferably, the hopper is a right-angled bucket-shaped container composed of a fixed plate, two side plates and an inclined plate; the fixed plate is fixedly connected to the drive mechanism, and the guide plate is disposed on the outer end face of the inclined plate.

[0012] Preferably, the limiting protrusion has an arc-shaped structure.

[0013] Preferably, the limiting protrusion has a strip-shaped structure, and its length is equal to the distance between the two guide plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By directly installing a mechanical impact generating component linked to each hopper, the gravitational potential energy is converted into impact kinetic energy by utilizing the change in motion state generated when the elevator runs to the drive wheel. This achieves complete automation and continuity of hopper unblocking without any external power or manual intervention, and the unblocking is timely and highly efficient. 2. The impact generating component has an extremely simple structure, consisting of only a few standard parts such as support rods, counterweight tubes, and limit nuts. It has no complex transmission mechanisms or elastic elements, making it not only inexpensive to manufacture but also reliable, maintenance-free, and long-lasting. Attached Figure Description

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0018] See Figure 1-5 In one embodiment of this utility model, a raw material lifting and conveying device for fertilizer mixing equipment includes: The elevator housing 1 has a fertilizer lifting chamber inside it, and the elevator housing 1 has a feed inlet 11 at the bottom and a discharge outlet 12 at the top. The drive mechanism includes a drive motor 2, a drive wheel 3, a driven wheel 4, and a transmission belt 5. The drive motor 2 is fixedly mounted on the top outer side of the hoist housing 1 via an external bracket. The drive wheel 3 is mounted on the inner top side of the hoist housing 1 and is driven by the drive motor 2. The driven wheel 4 is mounted on the inner lower part of the hoist housing 1. The transmission belt 5 is vertically mounted in the hoisting chamber of the hoist housing 1 and is transversely disposed between the drive wheel 3 and the driven wheel 4. In this embodiment, the transmission belt 5 is driven by the drive motor 2 and rotates clockwise. Hopper 6, multiple hoppers 6 are provided, and the multiple hoppers 6 are distributed at intervals along the length direction of the transmission belt 5; Impact generating components 7 are provided in multiple form and are arranged in correspondence with the hopper 6. Impact generating components 7 can generate self-excited vibration as the drive mechanism operates. This vibration can break the adhesion between fertilizer particles and the inner wall of the hopper, causing the fertilizer that has adhered or is about to clump to loosen and fall off, thereby achieving automatic and continuous online cleaning.

[0019] For details, please refer to Figures 3 to 5The hopper 6 is a right-angled bucket-shaped container welded together from a vertical fixed plate 61, two side plates 62, and an inclined plate 63. The fixed plate 61 is fixedly connected to the transmission belt 5 by bolts. The two right-angled triangular side plates 62 are vertically welded to both sides of the fixed plate 61. The inclined plate 63 is welded to the inclined side of the two side plates 62, together forming a bucket-shaped container with an inclined discharge bottom surface. In this embodiment, when the hopper 6 moves to the feed inlet 11 side, the hopper 6 is in an upward loading posture with its port facing upward. When the hopper 6 moves to the discharge outlet 12 side, the hopper 6 is in a downward discharge posture with its port facing downward. Figure 5 Hopper 6 is in a downward unloading posture; Furthermore, two strip-shaped guide plates 64 are fixedly provided at both ends of the outer surface of the inclined plate 63. The guide plates 64 are laid along the direction from the bottom end of the hopper 6 body to the port. Each guide plate 64 is provided with an oblong hole 641 along its length.

[0020] The impact generating component 7 includes a support rod 71, a counterweight tube 73, and two limiting nuts 72. The support rod 71 slides through two oblong holes 641 and extends to the outside of the guide plate 64 at both ends. The counterweight tube 73 is located inside the two guide plates 64 and is slidably fitted onto the support rod 71. This loose fit can generate more vibration. The two limiting nuts 72 are screwed onto both ends of the support rod 71 and are located outside the guide plate 64. In this embodiment, the outer diameter of both the counterweight tube 73 and the limiting nuts 72 is larger than the width of the oblong holes 641, forming a limiting groove between the counterweight tube 73 and the limiting nuts 72. This restrains the guide plate 64 within the limiting groove. This design ensures that the two ends of the support rod 71 slide synchronously during the sliding process, effectively preventing jamming.

[0021] During use, the impact generating component 7, following the drive mechanism, slides towards the lowest point under its own gravity after overturning the driving wheel 3 or the driven wheel 4, generating an instantaneous displacement. The impact vibration generated by hitting the guide plate 64 is then transmitted to the inner wall of the entire hopper 6, vibrating and removing the fertilizer adhering to the inner wall of the hopper 6. This design, through a simplified purely mechanical structure, realizes automatic and continuous unblocking of the hopper without manual intervention, significantly improving the continuity of equipment operation and production efficiency, while greatly reducing maintenance costs. Example 2: In the above example, the impact generating component 7 is always located at the bottom outside of the corresponding hopper 6 during the rising process. When the corresponding hopper 6 flips over the highest point of the drive wheel 3 and begins to unload into the discharge port 12, the impact generating component 7 will slide down due to its own weight and collide with the hopper 6. However, since the tilt angle of the inclined plate 63 of the hopper 6 has not yet reached its maximum value, the collision process is slow and the impact force is insufficient. The vibration clearing effect is not optimal. To overcome this limitation, this example introduces a delayed collision mechanism.

[0022] See Figure 6 On the outer end face of the inclined plate 63, two strip-shaped limiting protrusions 65 are fixedly provided. The length direction of these two limiting protrusions 65 is perpendicular to the length direction of the guide plate 64. At the same time, the distance between the two limiting protrusions 65 is less than the total sliding stroke of the impact generating component 7 in the waist-shaped hole 641 of the guide plate 64. The support rod 71 is located outside the limiting protrusions 65. When the hopper 6 flips over the apex of the drive wheel 3 and begins to unload, the impact generating component 7 slides down due to its own weight, but is immediately blocked by the limiting protrusion 65 located at the upper end of the sliding path. At this time, the hopper 6 continues to rotate, and the tilt angle of the inclined plate 63 continuously increases. When the hopper 6 rotates to a near-vertical state and the inclined plate 63 reaches its maximum tilt angle, the gravitational potential energy accumulated by the impact generating component 7 is sufficient to overcome the obstruction of the limiting protrusion 65. It slides down rapidly and experiences two collisions in sequence: the first collision occurs when the impact generating component 7 slides down and hits the limiting protrusion 65 below, and the second collision occurs when the impact generating component 7 continues to slide down to the bottom of the guide plate 64 and experiences the final collision. Through the delay and release effect of the limiting protrusion 65, it is ensured that the impact generating component 7 is released only when the tilt angle of the inclined plate 63 is at its maximum and its own potential energy has accumulated to its peak. This results in a faster final impact speed and greater kinetic energy, thereby generating more significant vibration and greatly improving the effect of removing adhering fertilizer.

[0023] In this embodiment, the length of the limiting protrusion 65 is equal to the distance between the two guide plates 64, ensuring that the limiting protrusion 65 can function as a whole lateral support structure, enabling it to make full-length contact with the counterweight tube 73 of the impact generating component 7, thus ensuring effective collision. At the same time, the limiting protrusion 65 is designed as an arc-shaped structure with a smooth outer surface. This design can effectively guide the counterweight tube 73 of the impact generating component 7 to smoothly transition and slide away, rather than rigidly blocking it. This achieves the delayed collision function while minimizing motion resistance and impact wear, ensuring the reliability and durability of the unblocking action.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
