Description

Technical Field

[0001] This utility model relates to the field of lily bulb screening technology, specifically to a lily bulb size grading and screening device. Background Technology

[0002] As an important material for flower propagation, the size grading of lily bulbs has a significant impact on planting results, flowering quality, and commercial value.

[0003] In existing technologies, the size grading of lily bulbs typically relies on vertical or multi-layered screening equipment. These devices present numerous inconveniences during installation and use, such as large footprint, complex structure, cumbersome operation, and the tendency for material accumulation during screening to clog the screen holes, affecting grading efficiency and accuracy. This not only increases the frequency of cleaning and maintenance but also reduces the overall continuity and automation level of the operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a lily bulb size grading and screening device with simple structure, which can effectively avoid clogging during the screening process and greatly improve screening efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a lily bulb size grading and screening device, including a horizontal screening tank, a collection box fixedly connected to the bottom surface of the horizontal screening tank, a feeding window at one end of the horizontal screening tank, and at least one screening window arranged along the length direction on the bottom surface of the horizontal screening tank. A detachable screening plate is fixedly connected inside the screening window, and the screening holes on adjacent screening plates increase in size sequentially in the same direction. A collection chamber is provided in the collection box below each corresponding screening plate. Two corresponding dividing discs are slidably connected inside the horizontal screening tank, forming an independent screening unit between the two dividing discs. A moving mechanism is provided on the horizontal screening tank to drive the two dividing discs to slide synchronously. A stirring rod located at the axis is rotatably connected between the two dividing discs. Turning blades arranged in a circular array are fixedly connected to the outer wall of the stirring rod. A rotating mechanism is provided inside the horizontal screening tank to drive the stirring rod to rotate.

[0006] As an improvement, the moving mechanism includes a moving block fixedly connected to the upper end of the dividing disc, a moving sliding hole that cooperates with the moving block is provided on the horizontal screening tank, a moving screw is rotatably connected to the upper end of the horizontal screening tank, the moving block is threadedly connected to the outer wall of the moving screw, and a first motor that drives the moving screw to rotate is fixedly connected to one end of the horizontal screening tank.

[0007] As an improvement, the rotating mechanism includes a rotating shaft rotatably connected to the center of the horizontal screening tank, a rotating hole that mates with the rotating shaft at the center of the stirring rod, a second motor that drives the rotating shaft to rotate fixedly connected to one end of the horizontal screening tank, a limiting slide bar fixedly connected to the outer wall of the rotating shaft, and a limiting groove that mates with the limiting slide bar on the inner wall of the rotating hole.

[0008] As an improvement, each side of the collection chamber is provided with a pull-out window, and a receiving box is slidably inserted into the pull-out window.

[0009] As an improvement, a sealed compartment door is provided on one side of the feeding window.

[0010] As an improvement, each of the turning blades is equipped with a cleaning brush at its end.

[0011] The advantages of this utility model compared with the prior art are as follows: It adopts a horizontal integrated design, which greatly reduces the floor space and overall height of the equipment compared with the traditional vertical or multi-layer structure, making installation and daily maintenance more convenient. By setting up an independent screening unit formed by a partition disc, and combining it with an axially movable stirring rod and turning blades, the lily bulbs can be continuously turned over during the screening process, effectively breaking up the stockpiled material, preventing screen hole blockage, ensuring the smoothness of the screening process and the grading efficiency. The screening plates are arranged along the length direction and the screen holes are progressively larger. With the movable partition disc, continuous multi-stage screening from the smallest to the largest size can be achieved without transferring materials in the middle, improving the work efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, a lily bulb size grading and screening device includes a horizontal screening tank 2, a collection box 1 fixedly connected to the bottom surface of the horizontal screening tank 2, a feeding window 15 at one end of the horizontal screening tank 2, a sealed door 16 on one side of the feeding window 15, and at least one screening window 3 arranged along the length direction on the bottom surface of the horizontal screening tank 2. A detachable screening plate 4 is fixedly connected inside the screening window 3, and the screening holes on adjacent screening plates 4 increase in size sequentially in the same direction. A collection chamber 17 is provided in the collection box below each corresponding screening plate 4, and a pull-out window is provided on one side of each collection chamber 17. A receiving box 18 is slidably inserted into the pull-out window.

[0019] The horizontal screening tank 2 has two correspondingly arranged dividing discs 5 slidably connected inside, forming an independent screening unit between the two dividing discs 5. The horizontal screening tank 2 is provided with a moving mechanism that drives the two dividing discs 5 to slide synchronously. The moving mechanism includes a moving block 11 fixedly connected to the upper end of the dividing disc 5. The horizontal screening tank 2 is provided with a moving sliding hole 14 that cooperates with the moving block 11. A moving screw 12 is rotatably connected to the upper end of the horizontal screening tank 2. The moving block 11 is threadedly connected to the outer wall of the moving screw 12. A first motor 13 that drives the moving screw 12 to rotate is fixedly connected to one end of the horizontal screening tank 2.

[0020] A stirring rod 6 located at the center of the axis is rotatably connected between the two separating discs 5. The outer wall of the stirring rod 6 is fixedly connected to a turning blade 19 arranged in a circular array. Each turning blade 19 is provided with a cleaning brush 20 at its end. The horizontal screening tank 2 is provided with a rotating mechanism that drives the stirring rod 6 to rotate. The rotating mechanism includes a rotating shaft 7 rotatably connected to the center of the axis inside the horizontal screening tank 2. The center of the stirring rod 6 is provided with a rotating hole that cooperates with the rotating shaft 7. A second motor 8 that drives the rotating shaft 7 to rotate is fixedly connected to one end of the horizontal screening tank 2. A limiting slide bar 9 is fixedly connected to the outer wall of the rotating shaft 7. The inner wall of the rotating hole is provided with a limiting slide groove 10 that cooperates with the limiting slide bar 9.

[0021] In practical use, before the device is started, the two separating discs 5, driven by the moving mechanism, are positioned at both ends of the screen plate 4 with the smallest screen holes in the horizontal screen tank 2. A closed initial screening unit is formed between these two discs. At this time, the sealed chamber door 16 located above this unit is opened, and all the lily bulbs to be graded are put into this unit through the feeding window 15, and then the chamber door is closed.

[0022] The rotating mechanism is activated, and the second motor 8 drives the rotating shaft 7 to rotate. The rotating shaft 7 transmits torque to the rotating shaft 6 through the cooperation of the limiting slide strip 9 on its outer wall and the limiting slide groove 10 in the rotating hole at the center of the rotating shaft 6, causing it to drive the rotating blades 19 arranged in a ring array to rotate at a uniform speed. During the rotation, the rotating blades 19 continuously and evenly turn and scatter the lily bulbs in the unit. During this process, bulbs smaller than the current aperture of the screen plate 4 pass through the screen holes under the action of gravity and turning, fall into the corresponding collection chamber 17 in the collection box 1 below, and are collected by the pull-out receiving box 18. At the same time, the cleaning brush 20 fixed to the end of the rotating blade 19 rotates with the blade and continuously cleans the surface of the screen plate 4, effectively preventing the screen holes from being blocked and ensuring screening efficiency.

[0023] Once this stage of screening is complete (i.e., no smaller seed bulbs fall), the moving mechanism is activated. The first motor 13 drives the moving screw 12 to rotate, which in turn drives the two moving blocks 11 threadedly connected to the screw. This causes the separating discs 5 on both sides to slide synchronously along the axial direction of the horizontal screening tank 2. The discs push the remaining large-sized seed bulbs, which have completed this stage of screening, to the adjacent next-stage screening plate 4 area. The screen aperture size of this stage screening plate 4 is larger than that of the previous stage.

[0024] Once the separating disc 5 moves to the new designated position and reforms into a closed screening unit, the rotating mechanism is restarted to repeat the above-mentioned tumbling and screening process. At this time, seed balls of the next smaller size will pass through the larger screen opening and fall into the corresponding collection chamber 17. This cycle continues until the seed balls have passed through all the screen plates 4 with different apertures, completing multi-stage precise screening. Finally, the largest seed balls remain in the unit between the separating discs 5, and the corresponding screen plate 4 can be removed to extract the seed material.
