Description

Technical Field

[0001] This invention relates to the field of substrate block seedling transplanting technology, and more specifically to a separating device for substrate block seedlings. Background Technology

[0002] In modern agriculture, substrate block seedling raising is a modern seedling raising method with significant advantages. Substrate blocks made of uniform substrate materials can provide a stable germination environment for seeds, resulting in uniform and consistent seedling emergence and a shorter seedling raising cycle. At the same time, the loose and breathable structure is conducive to the vigorous development of seedling roots, making seedlings more resistant to adverse conditions. When transplanting, the roots form a complete "root ball" with the substrate block, without damaging the roots and with a high survival rate and almost no seedling slowness. It can be widely used for a variety of crops such as vegetables, flowers, and fruit trees, and has great promotional value in modern agricultural seedling raising.

[0003] Most existing substrate block seedling transplanters are semi-automatic models, still requiring manual row picking of seedlings and placement into the seedling delivery and separation device. The automatic seedling picking action of the whole tray has not been realized, which seriously affects the work efficiency and makes it difficult to meet the needs of large-scale mechanized transplanting operations. In addition, the seedling delivery and separation device mostly uses mechanical structure to clamp the substrate block seedlings to achieve time sequence control and fixed-distance planting, which causes greater damage to the substrate block seedlings and seriously affects the survival rate after planting. Summary of the Invention

[0004] To address the above problems, this invention proposes a device for separating seedlings from substrate blocks, the specific technical solution of which is as follows: A seedling separation device for substrate block seedlings includes a seedling supply component, a seedling delivery component, a seedling separation component, and a seedling taking component. The seedling supply component includes a rodless cylinder and a mounting base installed on the movable end of the rodless cylinder. A support arm is mounted on the mounting base, and a fixed clamping plate and a movable clamping plate are mounted on the support arm. The movable clamping plate is connected to a clamping plate cylinder, which can drive the movable clamping plate to approach or move away from the fixed clamping plate. The seedling delivery component includes a first conveyor belt and a second conveyor belt connected to the first conveyor belt. The extension and retraction direction of the rodless cylinder is parallel to the conveying direction of the second conveyor belt. The rodless cylinder can drive the mounting base to move so that the movable clamping plate and the fixed clamping plate are positioned above the second conveyor belt. The seedling separation component includes a mounting plate vertically arranged on one side of the first conveyor belt. A guide rail is mounted on the mounting plate, and multiple sliders are mounted on the guide rail. The number of sliders is odd, and the sliders move along the first guide rail... An array of conveyor belts is arranged on the upper side of the first conveyor belt. Each slider is equipped with an air blowing pipe. A push rod mounting block is arranged on the lower side of the guide rail. A push-pull cylinder is connected to the lower side of the push rod mounting block. The push rod mounting block is connected to each slider except the center position through a connecting rod. The push-pull cylinder can drive the push rod mounting block to move, thereby increasing the distance between adjacent sliders. An air pump is also installed on the mounting plate. The air pump is connected to each air blowing pipe. The airflow blown out by the air blowing pipe can form an air wall perpendicular to the transport direction of the first conveyor belt. The seedling picking component includes a feeding cylinder and a fixed clamping plate. The feeding cylinder is installed on the upper side of the discharge end of the first conveyor belt through the fixed clamping plate. A finger cylinder is connected to the movable end of the feeding cylinder. Two clamping plates are installed on the lower side of the finger cylinder. The finger cylinder can drive the two clamping plates to move closer or further apart.

[0005] Furthermore, the support arm is connected to a drive motor that can rotate itself.

[0006] Furthermore, guide bars are provided on both sides of the first conveyor belt, and mounting plates are installed on the guide bars; guide baffles are provided on both sides of the second conveyor belt.

[0007] Furthermore, there are 5 sliders, and the connecting rods are divided into connecting long rods and connecting short rods. The upper end of the connecting rod is hinged to its corresponding slider, and the lower end of the connecting rod is hinged to the push rod mounting block.

[0008] Furthermore, the first conveyor belt is arranged at an angle, with the side closer to the second conveyor belt being higher.

[0009] Furthermore, the surfaces of the fixed clamp, the movable clamp, and the clamping plates are all covered with a silicone layer.

[0010] The beneficial effects of this invention are as follows: 1. The seedling feeding component can pick up the substrate block seedlings in a row. Compared with the traditional stem-clamping method, it can effectively avoid the failure of seedling picking caused by the stem being crooked. It can successfully pick up the entire row of substrate block seedlings and improve the success rate of seedling picking.

[0011] 2. The seedling separation component forms an air wall through air blowing, achieving contactless timing control and avoiding contact between the substrate block and the rigid structure. Compared with traditional substrate block seedling separation devices, it can reduce the clamping damage to the substrate block. The distance between the air blowing pipes can be adjusted to change the spacing between adjacent substrate block seedlings, thereby achieving control of different planting spacing for different crops, and has strong adaptability.

[0016] The present invention provides the following specific implementation schemes: like Figure 1 As shown, the present invention provides a seedling separation device for substrate block seedlings, including a seedling supply component 1, a seedling delivery component 2, a seedling separation component 3, and a seedling removal component 4.

[0017] like Figure 2 As shown, the seedling supply assembly 1 includes a rodless cylinder 113 and a mounting base 106 installed on the movable end of the rodless cylinder 113. A support arm 103 is mounted on the mounting base 106. A fixed clamping plate 101 and a movable clamping plate 102 are mounted on the support arm 103. The movable clamping plate 102 is connected to a clamping plate cylinder 112. The clamping plate cylinder 112 is mounted on the mounting base 106 through a cylinder fixing seat 111. The clamping plate cylinder 112 can drive the movable clamping plate 102 to approach or move away from the fixed clamping plate 101.

[0018] Preferably, the support arm 103 is connected to a drive motor 107 that can drive it to rotate. Correspondingly, the angle between the fixed clamp 101 and the support arm 103 is adjustable and a locking component is provided to lock the fixed clamp 101 so that the fixed clamp 101 remains vertical.

[0019] Preferably, there are two support arms 103, and a connecting shaft 104 is provided between the two support arms 103. Support rods 105 are provided at both ends of the connecting shaft 104. A transmission shaft 110 is also provided between the two support rods 105. A driven gear 108 is installed on the transmission shaft 110. A drive gear 109 is installed at the output end of the drive motor 107. The drive gear 109 and the driven gear 108 mesh, and the drive motor 107 can drive the support arm 103 to rotate. Then, the verticality of the fixing plate 101 can be adjusted to adapt to different substrate block seedling heights.

[0020] like Figure 3 As shown, the seedling delivery assembly 2 includes a first conveyor belt 203 and a second conveyor belt 210 connected to the first conveyor belt 203. The extension and retraction direction of the rodless cylinder 113 is parallel to the conveying direction of the second conveyor belt 210. The rodless cylinder 113 can drive the mounting base 106 to move so that the movable clamping plate 102 and the fixed clamping plate 101 are on the upper side of the second conveyor belt 210.

[0021] Preferably, the first conveyor belt 203 has guide bars 201 on both sides, a first support leg 204 on the lower side of the first conveyor belt 203, a fixed base plate 205 on the lower side of the first support leg 204, and the guide bars 201 and the first support leg 204 are connected by a T-connecting plate 202. The first conveyor belt 203 is driven by a first conveyor motor 208, a synchronous belt 207, and a synchronous pulley 206. The second conveyor belt 210 has guide plates 211 on both sides, a second support leg 212 on the lower side of the second conveyor belt 210, and is driven by a second conveyor motor 209.

[0022] like Figure 4 As shown, the seedling separation assembly 3 includes a mounting plate 303 vertically arranged on one side of the first conveyor belt 203. The mounting plate 303 is mounted on the guide bar 201. A guide rail 304 is mounted on the side of the mounting plate 303 closest to the first conveyor belt 203. A plurality of sliders 305 are mounted on the guide rail 304. The number of sliders 305 is odd. The sliders 305 are arranged in an array on the upper side of the first conveyor belt 203 along the transport direction of the first conveyor belt 203. Each slider 305 is equipped with an air blowing pipe 307. A push rod mounting block 311 is arranged on the lower side of the guide rail 304. The push rod mounting block 311 is slidably mounted on the mounting plate 303. A push-pull cylinder 312 is connected to the push rod mounting block 311, which is connected to each slider 305 except for the center position via a connecting rod. The push-pull cylinder 312 can drive the push rod mounting block 311 to move, thereby increasing the distance between adjacent sliders 305. An air pump 301 is also installed on the mounting plate 303. The air pump 301 is connected to each air blowing pipe 307 via an air pipe 302. The airflow blown out by the air blowing pipe 307 can form an air wall perpendicular to the transport direction of the first conveyor belt 203. A Venturi tube structure is used here, which can form a high-speed jet to generate a negative pressure zone, driving the surrounding air to form an "air wall" perpendicular to the direction of the conveyor belt.

[0023] Preferably, in this embodiment, there are 5 sliders 305, and the connecting rods are divided into connecting long rods 308 and connecting short rods 309. The middle slider 305 is not connected to the connecting rod. The sliders 305 on the outermost side are connected to the push rod mounting block 311 through the connecting long rods 308. The sliders 305 on the next outermost side are connected to the push rod mounting block 311 through the connecting short rods 309. The upper end of the connecting rod is hinged to the corresponding slider 305, and the lower end of the connecting rod is hinged to the push rod mounting block 311 through the hinge post 310.

[0024] Preferably, the air blowing pipe 307 is mounted on its corresponding slider 305 via the air blowing pipe mounting plate 306.

[0025] like Figure 5 As shown, the seedling taking component 4 includes a feeding cylinder 404 and a fixed clamping plate 402. The feeding cylinder 404 is mounted on the fixed clamping plate 402 via a hinged cylinder seat 405. The feeding cylinder 404 is mounted on the upper side of the discharge end of the first conveyor belt 203 via the fixed clamping plate 402. The movable end of the feeding cylinder 404 is connected to a finger cylinder 401. Two clamping plates 403 are installed on the lower side of the finger cylinder 401. The finger cylinder 401 can drive the two clamping plates 403 to move closer or further apart.

[0026] Preferably, the first conveyor belt 203 is arranged at an angle, with the side closer to the second conveyor belt 210 being higher, to facilitate the final seedling placement.

[0027] Preferably, the surfaces of the fixed clamp 101, the movable clamp 102, and the clamping piece 403 are all provided with a silicone layer.

[0028] Preferably, a controller is also provided, which is connected to each electrical component in real time. The controller can adjust the air pressure of the air pump 301 in real time according to the condition and size of the substrate block seedlings, and can also adjust the clamping degree of the finger cylinder 401 in real time according to the condition and size of the substrate block seedlings to avoid damage to the substrate block seedlings.

[0029] The working process of this invention is as follows: The entire tray of substrate block seedlings is transported to the seedling collection position via a conveyor. The height of the fixed clamping plate 101 and the movable clamping plate 102 is preset by the drive motor 107. The rodless cylinder 113 is activated, moving the fixed clamping plate 101 and the movable clamping plate 102 laterally to the seedling collection position. Then, the clamping plate cylinder 112 extends, driving the movable clamping plate 102 to clamp the entire row of substrate block seedlings. After clamping, the rodless cylinder 113 is activated, moving the entire row of substrate block seedlings above the second conveyor belt 210 and placing the seedlings on the second conveyor belt 210. The substrate block seedlings are then transported onto the second conveyor belt 210. As they pass the seedling separation component 3, the air pump... When 301 is activated, the air blower 307 sprays air to form an air wall that blocks the advance of the substrate seedlings. Then, the push-pull cylinder 312 drives the push rod mounting block 311 to move, and the air blower 307 on the slider 305 changes pitch to change the spacing between adjacent substrate seedlings, thereby controlling the planting spacing. After separating adjacent substrate seedlings, the air pump 301 is turned off, the air wall disappears, and the substrate seedlings continue to move forward to below the seedling picking component 4. The finger cylinder 401 contracts, causing the clamping plate 403 to clamp the substrate seedling. The cylinder extends, causing the finger cylinder and clamping plate 403 to move to the seedling placement position. Then, the finger cylinder 401 resets, placing the substrate seedling into the planter.

[0030] Compared to semi-automatic substrate block seedling transplanters, this invention can fully automate the picking, delivery, and separation of substrate block seedlings, reducing manual labor and improving work efficiency. The seedling supply component 1 clamps the substrate block seedlings in a row, effectively avoiding seedling removal failures caused by stem tilting compared to traditional stem clamping seedlings, and can successfully remove the entire row of substrate block seedlings, improving the seedling removal success rate. The seedling separation component 3 forms an air wall through air blowing, achieving contactless timing control and avoiding contact between the substrate block and the rigid structure. Compared to traditional substrate block seedling separation devices, it can reduce clamping damage to the substrate block. The distance between the air blowing pipes 307 can be adjusted to change the spacing between adjacent substrate block seedlings, thereby achieving control of different planting spacing for different crops, making it highly adaptable.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
