Description

Technical Field

[0001] This utility model relates to the technical field of seedling bed components, and in particular to a chain stabilizing device for seedling beds. Background Technology

[0002] The chains in existing seedling beds are mostly W-shaped, with the chain and sprockets operating in a flexible transmission configuration. At the connection between the upper and lower sprockets on the seedling bed, the V-shaped chain has an excessively long span, causing the inclined portion of the chain to sag in an arc or parabolic shape. When the chain operates in this arc-shaped manner, the transmission delay caused by the accumulated gaps along the chain length leads to swaying left and right or jumping up and down on the chain and the seedling tray it supports. This affects the overall stability of the tray's operation and can easily cause the chain to derail. Utility Model Content

[0042] Please see Figures 1 to 6 This embodiment provides a chain stabilizing device for a seedling bed. The seedling bed includes a support 10, on which multiple sprockets 20 are provided. A chain 30 is looped around the multiple sprockets 20 to form a W-shaped conveying track on the support 10. The chain stabilizing device includes a fixed beam group 1, a stabilizing guide rod 2, and an adjustable connecting assembly 3.

[0043] Fixed beam assembly 1 is horizontally set on support 10 and located in the middle of W-shaped conveying trajectory. Fixed beam assembly 1 includes an upper fixed beam 11 and a lower fixed beam 12 arranged in parallel.

[0044] The stabilizing guide rod 2 is set parallel to the chain 30 and is used to support the inclined part of the chain 30. The two ends of the stabilizing guide rod 2 are connected to the upper fixed beam 11 and the lower fixed beam 12 through the adjustable connecting assembly 3.

[0045] The W-shaped conveying trajectory is the overall shape of the chain 30 on the support 10. The chain 30 can drive the seedling basket to move on the W-shaped conveying trajectory. The upper fixed beam 11 and the lower fixed beam 12 are horizontally set on the support 10. Each fixed beam can be a multi-section crossbeam. The two ends of the crossbeam are respectively installed on the vertical square tube beam of the support 10. The stabilizing guide rod 2 is set near the lower part of the inclined part of the chain 30, so as to support the inclined part of the chain 30 and prevent the inclined part of the chain 30 from sagging, thereby solving the problem of the chain 30 shaking due to the excessive span of the chain 30. The two ends of the stabilizing guide rod 2 are respectively connected to the upper fixed beam 11 and the lower fixed beam 12 through the adjustable connecting components 3, so as to adjust the horizontal position and angle of the stabilizing guide rod 2, which is convenient to adapt to different specifications of W-shaped seedling beds.

[0046] The chain stabilizing device for seedling beds provided in this embodiment sets up upper and lower fixed beams on the support 10 and sets up a stabilizing guide rod 2 between the upper and lower fixed beams. This allows the stabilizing guide rod 2 to support the inclined part of the chain 30, avoiding the problem of the chain 30 jumping due to the excessively long span and the sagging of the inclined part. This enhances the running stability of the chain 30.

[0047] Furthermore, the stabilizing guide rod 2 is made of square steel, and the diameter of the square steel is smaller than the width of the groove in the chain 30.

[0048] Among them, the chain 30 is usually a roller chain, and its chain plate size is larger than that of the sleeve roller. A groove is formed between the chain plates in the length direction of the chain 30. The diameter of the square steel is smaller than the width of the groove of the chain 30 so that the chain 30 can slide on the stabilizing guide rod 2.

[0049] Further, please see Figure 3 The stabilizing guide rod 2 has a transition slope 21 at the end opposite to the running direction of the chain 30. The transition slope 21 is inclined away from the chain 30 along the opposite direction of the running direction of the chain 30.

[0050] Specifically, if the chain 30 runs downwards, the transition slope 21 is located at the top of the stabilizing guide rod 2; if the chain 30 runs upwards, the transition slope 21 is located at the bottom of the stabilizing guide rod 2. This allows the chain 30 to slide smoothly from the end of the stabilizing guide rod 2 onto the stabilizing guide rod 2 during operation, preventing the chain 30 from getting stuck.

[0051] Further, please see Figure 2 and Figure 3 :

[0052] The adjustable connection assembly 3 includes angle steel. The two ends of the stabilizing guide rod 2 can be detachably connected to the fixed beam via angle steel. The fixed beam can be provided with multiple mounting holes, which facilitates the selection of a suitable horizontal position and angle when installing the stabilizing guide rod 2.

[0053] The adjustable connection assembly 3 includes a rotating connection structure 31 and a sliding connection structure 32. One of the upper fixed beam 11 and the lower fixed beam 12 is connected to one end of the stabilizing guide rod 2 through the rotating connection structure 31, and the other is connected to the other end of the stabilizing guide rod 2 through the sliding connection structure 32.

[0054] When the upper fixed beam 11 is connected to one end of the stabilizing guide rod 2 via the rotating connection structure 31, and the lower fixed beam 12 is connected to the other end of the stabilizing guide rod 2 via the sliding connection structure 32, the stabilizing guide rod 2 can rotate relative to the upper fixed beam 11, thereby adjusting the angle of the stabilizing guide rod 2. When one end of the stabilizing guide rod 2 rotates, the other end slides on the lower fixed beam 11 via the sliding connection structure 32. After setting the angle and position of the stabilizing guide rod 2, the adjustable connection component 3 can be locked to fix the position of the stabilizing guide rod 2. The same applies when the upper fixed beam 11 is connected to the stabilizing guide rod 2 via the sliding connection structure 32, and the lower fixed beam 12 is connected to the other end of the stabilizing guide rod 2 via the rotating connection structure 11.

[0055] Further, please see Figure 3 The rotating connection structure 31 includes a first fixed groove 311, a rotating hole 312, and a rotating pin group 313.

[0056] The first fixing groove 311 is provided on the upper fixing beam 11 or the lower fixing beam 12 and extends along its length.

[0057] Rotation hole 312 is located at one end of stabilizing guide rod 2.

[0058] The rotating pin assembly 313 passes between the first fixed groove 311 and the rotating hole 312, so that one end of the stabilizing guide rod 2 can slide along the direction of the first fixed groove 311, thereby facilitating the adjustment of the horizontal position of the stabilizing guide rod 2. After the horizontal position and angle of the stabilizing guide rod 2 are adjusted, the rotating pin assembly 313 can be locked to fix the position of the stabilizing guide rod 2.

[0059] Further reading is available upon request. Figure 3 The sliding connection structure 32 includes a second fixed groove 321 and a sliding groove 322.

[0060] The second fixing groove 321 is provided on the upper fixing beam 11 or the lower fixing beam 12 and extends along its length.

[0061] The sliding groove 322 is located at the other end of the stabilizing guide rod 2 and extends along its length.

[0062] A rotating pin assembly 313 is provided between the second fixed groove 321 and the sliding groove 322.

[0063] The rotating connection structure 31 and the sliding connection structure 32 can each have a rotating pin assembly 313. The rotating pin assembly 313 allows the two ends of the stabilizing guide rod 2 to move along the length direction of the first fixed groove 311 and the second fixed groove 321, respectively. When one end of the stabilizing guide rod 2 moves along the length direction of the first fixed groove 311 and rotates relative to the upper fixed beam 11 or the lower fixed beam 12, the rotating pin assembly 313 in the sliding connection structure 32 can adjust the relative position of the second fixed groove 321 and the sliding groove 322 with the movement of the stabilizing guide rod 2. After the position is adjusted, it can be locked by the two rotating pin assemblies 313, thereby fixing the position of the stabilizing guide rod 2.

[0064] Furthermore:

[0065] The rotating pin assembly 313 includes bolts and nuts, thereby enabling the rotation and fixation of the stable guide rod 2 on the fixed beam.

[0066] Please see Figure 4 The rotating pin assembly 313 may also include a guide rod 3131. A rack 3132 is connected to the guide rod 3131 at the inner part of the upper fixed beam 11 or the lower fixed beam 12. A gear 3133 is meshed with the end of the rack 3132 away from the guide rod 3131. The gear 3133 is rotatably connected to the upper fixed beam 11 or the lower fixed beam 12 and is connected to a handle outside the upper fixed beam 11 or the lower fixed beam 12.

[0067] The smooth surface of the rack 3132 can be in close contact with the inner wall of the upper fixed beam 11 or the lower fixed beam 12, and is suitable for sliding in the upper fixed beam 11 or the lower fixed beam 12. When the handle is turned, the gear 3133 can be driven to rotate, thereby driving the rack 3132 that meshes with the gear 3133 to slide, and then the guide rod 3131 can slide in the first fixed groove 311 or the second fixed groove 321. The guide rod 3131 passes through both ends of the stabilizing guide rod 2, thereby driving the end of the stabilizing guide rod 2 to move horizontally and rotate.

[0068] Further, please see Figure 5 and Figure 6 A roller 22 is provided between the stabilizing guide rod 2 and the chain 30. The roller 22 is a rounded triangle with the sides of the rounded triangle recessed inward to form a chain sleeve abutment part 221. The chain sleeve abutment part 221 can contact the sleeve on the chain 30. When the chain 30 is running, the sleeve on the chain 30 drives the chain sleeve abutment part 221 to rotate, thereby driving the second roller 221 to rotate. Since the chain 30 is not a solid structure, but a structure of sleeve and hollow interlocking, this roller structure can make the transmission between the second roller 35 and the chain 30 smoother.

[0069] Explanation of the principle:

[0070] The W-shaped conveyor track is the overall shape of the chain 30 on the support 10. The chain 30 can drive the seedling basket to move on the W-shaped conveyor track. The upper fixed beam 11 and the lower fixed beam 12 are horizontally set on the support 10. Each fixed beam can be a multi-section crossbeam. The two ends of the crossbeam are respectively installed on the vertical square tube beam of the support 10. The stabilizing guide rod 2 is set near the lower part of the inclined part of the chain 30, so as to support the inclined part of the chain 30 and prevent the inclined part of the chain 30 from sagging, thereby solving the problem of the chain 30 shaking due to the excessive span of the chain 30. The two ends of the stabilizing guide rod 2 are respectively connected to the upper fixed beam 11 and the lower fixed beam 12 through the adjustable connecting components 3, so as to adjust the horizontal position and angle of the stabilizing guide rod 2, which is convenient to adapt to different specifications of W-shaped seedling beds.
