Description

Technical Field

[0001] The invention relates to the technical field of seedling raising equipment, in particular to an automatic filling device for rock wool blocks. Background Art

[0002] Factory-based seedling cultivation can significantly improve seedling quality and survival rate, shorten the seedling cultivation cycle, save resources and protect the environment by precisely controlling the growth environment. At the same time, it achieves efficient and standardized production, bringing significant economic benefits and improved production efficiency to modern agriculture.

[0003] As a new type of seedling matrix, rock wool blocks are formed by melting natural rocks at high temperatures. They have good air permeability and water retention, and can provide a good growth environment for seedlings. Before factory seedling cultivation, rock wool blocks need to be filled into foam seedling trays. However, rock wool blocks are cylindrical and have different shapes at both ends (one end is flat and the other end is concave). During the filling process, the concave end needs to be facing upward, that is, the rock wool block is in a positive state, which is convenient for later sowing. However, this operation process is labor-intensive and inefficient, and the irritation of its fine fibers and the potential of its chemical components can easily irritate skin cells and cause allergic reactions.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it is necessary to understand that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0035] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0036] It should be noted that the rock wool block is cylindrical as a whole, one end of which is flat and the other end is a concave arc surface. For the convenience of description, the state of the rock wool block with "concave arc surface facing upward and flat surface facing downward" is called the "positive state" (also because it is consistent with the final state of the rock wool block in the seedling tray 21), and the state of "concave arc surface facing downward and flat surface facing upward" is called the "reverse state". The rock wool block is in a vertical state, which means that its axis extends vertically. The positive state or the reverse state are two forms of the rock wool block in a vertical state; the rock wool block is in a horizontal state, which means that its axis extends horizontally, that is, the state of the rock wool block lying flat.

[0037] The present invention provides a rock wool block automatic filling device suitable for factory seedling cultivation, please refer to Figures 1 to 5The device includes a support mechanism 1, a feeding mechanism, an adjustment mechanism, a pressing mechanism and a seedling tray moving mechanism.

A support column 33 inclined toward the feed port is provided at the corner of the adjustment tube 13. The support column 33 is arranged in the slot of the fixed block 29. The support column 33 is used to prevent the rock wool block in the reverse state from falling directly out of the discharge port along the pipeline. The rock wool blocks that fall into the tube in the forward state from the feed port of the self-adjusting tube 13 can directly fall out from the discharge port along the pipeline, while the rock wool blocks that fall into the tube in the reverse state are blocked by the stop column 33 and can not fall out along the original path until the feed port of the self-adjusting tube 13 rotates to the bottom; a second belt conveyor 14 extending left and right is provided at the lower part of the fixed bracket 15, and a gap 34 is provided between the right end of the conveyor belt in the second belt conveyor 14 and the right end of the fixed bracket 15 for only one rock wool block in a vertical state to pass through, and the rock wool blocks that fall out of the self-adjusting tube 13 fall onto the second belt conveyor 14 and fall onto the seedling tray 21 through the gap 34.

[0048] Specifically, the angle between the axis of the support column 33 and the axis of the discharge port of the steering tube 13 is 45°.

[0049] As a preferred solution of the present invention, the length of the support column 33 is adjustable, so that the device of the present invention can be applied to rock wool blocks of different diameters.

[0050] Preferably, the end of the support column 33 extending into the redirecting tube 13 is in the shape of a convex arc surface, so that the support column 33 can better cooperate with the rock wool block. The support column 33 is made of rubber material to avoid damage to the rock wool block.

[0056] <Seedling tray moving mechanism>

[0057] The seedling tray moving mechanism is arranged on the second support frame 102, including a longitudinal drive component and a transverse drive component arranged on the longitudinal drive component. The transverse drive component and the longitudinal drive component can move the holes to be filled on the seedling tray 21 to be directly below the gap 34.

A fixed plate is placed above the second support member 25, and a seedling tray 21 is placed on the fixed plate.

[0059] It should be noted that the automatic filling device of the present invention is provided with a controller electrically connected to each motor, and the rotation of each motor is controlled by the controller. The automatic filling device of the present invention is also provided with a visual recognition system on the feeding mechanism and the adjustment mechanism, respectively. The controller cooperates with the visual recognition system so that the rock wool blocks on the first belt conveyor 8 just fall into the adjustment tube 13, and the rock wool blocks dropped from the second belt conveyor 14 just fall into the target position of the seedling tray 21. Among them, the visual recognition system is respectively arranged at appropriate positions of the feeding mechanism and the adjustment mechanism.

[0060] The specific method of using the automatic filling device of rock wool blocks provided by the present invention is: first, the disordered rock wool blocks are placed in the storage box 7, the output shaft of the feeding motor 3 rotates to drive the feeding gear 4 to rotate, and then the meshing feeding rack 5 drives the push-pull plate 704 to move up and down, and the rock wool blocks rise in a step-by-step manner on the fixed plate 703 and the push-pull plate 704 to the conveyor belt of the first belt conveyor 8, the rock wool blocks continue to move on the first belt conveyor 8, and fall into the adjustment tube 13 through the concave slide 11, and the output shaft of the adjustment motor 31 rotates to drive the disc 12 and then drives the adjustment tube 13 to rotate counterclockwise. In order to ensure that the concave arc surface of all rock wool blocks faces the same direction, the direction adjustment is divided into two situations: (1) When the rock wool block falls in the positive state of "concave arc surface facing upward and flat surface facing downward", after contacting the stop column 33, it will directly slide out from the discharge port at the lower end of the adjustment tube 13 as the disc 12 rotates. At this time, the rock wool block falls on the second belt conveyor 14 in the positive state; (2) When the rock wool block falls in the reverse state of "concave arc surface facing downward and flat surface facing upward", it will be stopped when it contacts the stop column 33. As the disc 12 continues to rotate, when the adjustment tube 13 rotates to the feed port facing downward, the rock wool block will slide out along the original path. In this way, the rock wool block also falls on the second belt conveyor 14 in the positive state. Under the action of the second belt conveyor 14, the rock wool block will move into the gap 34 and fall; at the same time, the output shaft of the pressing motor 19 rotates to drive the pressing gear 17 to rotate, and the pressing gear 17 engages with the pressing rack 18 to drive the pressing rod 20 to move up and down, thereby pressing the rock wool block into the hole to be filled on the seedling tray 21; after completing a single press, the output shaft of the transverse motor 23 rotates to drive the second screw 22 to rotate, thereby driving the seedling tray 21 to move left and right by a transverse hole spacing. After the entire row is filled, the output shaft of the longitudinal motor 32 rotates to drive the first screw 30 to rotate, thereby driving the seedling tray 21 to move forward and backward by a longitudinal hole spacing, and so on and so forth until the entire seedling tray 21 is filled.

[0061] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any equivalent changes or modifications made according to the essence of the present invention should be included in the protection scope of the present invention.
