Description

Technical Field

[0001] This utility model relates to the technical field of scallion cultivation, and in particular to a scallion seedling division device. Background Technology

[0002] Scallions are primarily consumed for their tender leaves, serving as an indispensable seasoning in dishes, fish dishes, and soups. They are also a major variety used in dehydrated vegetable processing. While scallions can be propagated by seed, division is preferred. Specifically, when dividing and transplanting, leaves that are too long from the growing point should be trimmed; the tips of the fibrous roots should also be trimmed, leaving 2-3 cm to encourage new root development. Transplant 1-2 scallions per hole. Currently, in the process of dividing and propagating seedlings, workers often use scissors to cut off the leaves and fibrous root tips, a method that is time-consuming and labor-intensive. Patent publication number CN222396155U discloses a scallion seedling division device, including a second support frame. The top of the second support frame has a feeding mechanism for dispensing scallion seedlings. The feeding mechanism includes a feeding trough located at the top of the second support frame, with a feeding pipe fixedly connected to the bottom of the feeding trough. The bottom of the feeding pipe passes through the second support frame and extends out of the bottom of the second support frame. A cutter is located at the top of the second support frame. The device can cut the leaves and roots of scallion seedlings through a feeding mechanism. However, because the feeding mechanism is not equipped with a limiting mechanism, the position where the scallion seedling falls to the cutting point is uncertain. This results in inconsistent lengths of leaves or roots cut by the cutter, and even over-cutting, which affects the subsequent planting value of the scallion seedlings. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a scallion seedling division device. By using multiple converging strips to restrict the falling position of the scallion seedlings, it is easier for the cutter to cut the leaves and roots of the scallion seedlings, thereby reducing the occurrence of over-cutting.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A scallion seedling division device includes: a frame with a feeding hopper, two mounting rollers rotatably mounted on the frame, the two mounting rollers being connected to a first drive mechanism for driving the two mounting rollers to rotate towards each other, the mounting rollers having a plurality of gathering strips spaced apart along their length, the plurality of gathering strips being located below the feeding hopper; two cutters movably mounted on the frame, the gathering strips being located between the two cutters, the two cutters being connected to a second drive mechanism for driving the two cutters to move horizontally relative to the gathering strips; and a sensor mounted on the frame for detecting material discharge from the feeding hopper, the sensor being electrically connected to a control module, the control module being electrically connected to the first drive mechanism and the second drive mechanism.

[0005] In the above-described scallion seedling division device, scallion seedlings are intermittently fed vertically into the hopper. Sensors detect the falling of the scallion seedlings and generate signals that are fed back to the control module. This causes the first drive mechanism to drive multiple gathering strips to gather and limit the falling position of the scallion seedlings, ensuring that the white part of the scallion seedling is positioned between two cutting blades. Then, the control module controls the second drive mechanism to drive the cutting blades to move laterally, thereby cutting the leaves and roots of the scallion seedlings. This helps to ensure that the cutting length of multiple scallion seedlings is consistent and avoids over-cutting of the scallion seedlings.

[0006] Understandably, the sensor uses an infrared sensor to detect the falling material. The control module uses a PLC module, with the sensor located below the discharge channel of the hopper. The hopper has a rectangular discharge channel, which facilitates the vertical falling of scallion seedlings to the gathering bar and allows multiple seedlings to be placed in a single row. Furthermore, the distance between the lower end of the gathering bar and the lower end of the discharge channel should be less than the overall height of the scallion seedlings, allowing some leaves to be embedded within the discharge channel during cutting, thus maintaining the seedlings' upright position. Additionally, the time interval for manually adding scallion seedlings can be adjusted according to the time required for a single cutting operation.

[0007] Furthermore, the first drive mechanism includes gears connected to each of the mounting rollers. One gear has a first rack meshing on its upper side, and the other gear has a second rack meshing on its lower side. A connecting rod connects the first rack and the second rack. One of the mounting rollers is connected to a motor that drives its rotation. Specifically, the motor drives one mounting roller to rotate forward, causing one gear to move the second rack via the first rack, thereby driving another gear to drive the other mounting roller to rotate in the opposite direction. This facilitates driving the two mounting rollers to rotate towards each other, causing the multiple gathering strips to converge and limit the falling position of the scallion seedlings. It is understood that the motor is electrically connected to a control module, which controls the forward and reverse rotation of the motor to drive the multiple gathering strips to open or close.

[0008] Furthermore, the frame includes two opposing first side frames, each first side frame including two parallel uprights, and the mounting roller is rotatably disposed between the two uprights, thereby providing mounting positions for the two mounting rollers.

[0009] Furthermore, a first mounting plate is provided between two adjacent uprights. The first mounting plate has a horizontally oriented groove. The connecting rod is connected to a sliding rod that mates with the groove. Nuts are threaded onto both ends of the sliding rod, one nut abutting against the connecting rod and the other against the first mounting plate. Specifically, the cooperation between the sliding rod and the groove facilitates guiding and limiting the movement of the connecting rod, thereby enabling the first and second racks to translate relative to the first mounting plate. The sliding rod includes a smooth rod portion that mates with the groove. Threaded rods are provided at both ends of the smooth rod portion. Each nut mates with a corresponding threaded rod, thereby adjusting the position of the nut to adjust the clearance between the connecting rod and the first mounting plate.

[0010] Furthermore, two limiting plates are spaced apart along the height direction between the two first side frames, and the gathering bar is rotatably located between the two limiting plates. One side of each cutter faces the corresponding limiting plate, thereby facilitating the cutter to work with the limiting plate to better cut the leaves and roots of the scallion seedlings.

[0011] Furthermore, a rectangular frame is connected to one side of each of the two cutters, and a push plate is connected between the two rectangular frames. The second driving mechanism is a cylinder mounted on the frame, and the telescopic end of the cylinder is connected to the push plate. Specifically, the cylinder drives the push plate to move, thereby causing the two cutters to move synchronously in the horizontal direction. It can be understood that the cylinder is a bidirectional cylinder, and the air supply line of the bidirectional cylinder is equipped with a reversing valve. The control module is electrically connected to the reversing valve, thereby changing the air supply direction through the reversing valve, so that the bidirectional cylinder drives the push plate to move reciprocally.

[0012] Furthermore, the frame includes two opposing second side frames, the two second side frames being connected to a second mounting plate, and the cylinder being disposed on the second mounting plate, thereby utilizing the second mounting plate to provide the cylinder's mounting position.

[0013] Furthermore, the second side frame includes two horizontally arranged crossbars. The two lower crossbars, together with the second mounting plate, define a material discharge channel. A brush is positioned between the two upper crossbars, and the brush is used to abut against the upper cutter. Specifically, a collection box is placed below the material discharge channel, the cutter has a flat structure, and the brush is located in the middle of the material discharge channel. After the cutter cuts the leaves of the scallion seedlings, the leaves fall onto the upper surface of the cutter. The cutter returns to the position of the brush, and the brush pushes the leaves into the material discharge channel, thereby collecting the cut leaves and reducing the difficulty of subsequent manual cleaning of the cut leaves.

[0014] Furthermore, the gathering strip has an arc-shaped structure, and its inner wall is provided with an elastic layer. This elastic layer cushions the falling scallion seedlings, reducing damage. The multiple gathering strips are spaced apart to allow the roots of the scallion seedlings to be exposed, facilitating subsequent cutting.

[0015] Compared with existing technologies, this utility model has at least the following beneficial effects: 1. This utility model uses multiple converging strips to limit the falling position of scallion seedlings, which helps the cutter to cut the leaves and roots of the scallion seedlings, thereby reducing the phenomenon of over-cutting.

[0016] 2. This utility model, through the cooperation of a motor, two gears, a first rack and a second rack, facilitates the driving of two mounting rollers to rotate in opposite directions, thereby driving multiple gathering strips to gather together to limit the falling position of the scallion seedlings.

[0023] See Figures 1 to 3 A scallion seedling division device includes: a frame 100, a hopper 110 on the frame 100, two mounting rollers 120 rotatably mounted on the frame 100, the two mounting rollers 120 being connected to a first drive mechanism, the first drive mechanism driving the two mounting rollers 120 to rotate towards each other, the mounting rollers 120 having a plurality of gathering strips 121 spaced apart along their length, the plurality of gathering strips 121 being located below the hopper 110; two cutters 200 movably mounted on the frame 100, the gathering strips 121 being located between the two cutters 200, the two cutters 200 being connected to a second drive mechanism, the second drive mechanism driving the two cutters 200 to move horizontally relative to the gathering strips 121; and a sensor mounted on the frame 100, the sensor detecting material discharge from the hopper 110, the sensor being electrically connected to a control module, the control module being electrically connected to the first drive mechanism and the second drive mechanism.

[0024] In the above-described scallion seedling division device, scallion seedlings are intermittently fed vertically into the hopper 110. Sensors detect the falling of the scallion seedlings and generate signals that are fed back to the control module. This causes the first drive mechanism to drive multiple gathering bars 121 to gather and limit the falling position of the scallion seedlings, so that the white part of the scallion seedling is located between two cutters 200. Then, the control module controls the second drive mechanism to drive the cutters 200 to move laterally, thereby cutting the leaves and roots of the scallion seedlings. This helps to make the cutting length of multiple scallion seedlings more consistent and avoids over-cutting of the scallion seedlings.

[0025] Understandably, the sensor uses an infrared sensor to detect the falling material. The control module uses a PLC module. The sensor is located below the discharge channel of the hopper 110. The hopper 110 has a rectangular discharge channel, which facilitates the vertical falling of scallion seedlings to the collecting strip 121 and also allows multiple scallion seedlings to be placed in a single row. Furthermore, the distance between the lower end of the collecting strip 121 and the lower end of the discharge channel should be less than the overall height of the scallion seedlings, allowing some leaves to be embedded in the discharge channel during cutting, thus maintaining the scallion seedlings' upright position. Additionally, the time interval for manually adding scallion seedlings can be adjusted according to the time required for a single scallion seedling cut.

[0026] See Figures 1 to 3 Furthermore, the first drive mechanism includes a gear 122 connected to each mounting roller 120. One gear 122 has a first rack 123 meshing on its upper side, and the other gear 122 has a second rack 124 meshing on its lower side. A connecting rod 125 connects the first rack 123 and the second rack 124. One mounting roller 120 is connected to a motor 126 that drives it to rotate. Specifically, the motor 126 drives one mounting roller 120 to rotate forward, causing one gear 122 to move the second rack 124 via the first rack 123. This, in turn, drives the other gear 122 to rotate the other mounting roller 120 in the opposite direction. This facilitates the rotation of the two mounting rollers 120 towards each other, causing the multiple gathering strips 121 to converge and limit the falling position of the scallion seedlings. It is understood that the motor 126 is electrically connected to a control module, which controls the forward and reverse rotation of the motor 126 to drive the multiple gathering strips 121 to open or close.

[0027] See Figures 1 to 3 Furthermore, the frame 100 includes two opposing first side frames, each first side frame including two parallel uprights 101, and the mounting rollers 120 are rotatably disposed between the two uprights 101, thereby providing mounting positions for the two mounting rollers 120.

[0028] See Figures 1 to 3Furthermore, a first mounting plate 130 is provided between two adjacent uprights 101. The first mounting plate 130 has a horizontally oriented groove 131. A connecting rod 125 is connected to a sliding rod 127 that mates with the groove 131. Nuts 128 are threaded onto both ends of the sliding rod 127, with one nut 128 abutting against the connecting rod 125 and the other nut 128 abutting against the first mounting plate 130. Specifically, the engagement of the sliding rod 127 with the groove 131 facilitates guiding and limiting the movement of the connecting rod 125, thereby enabling the first rack 123 and the second rack 124 to translate relative to the first mounting plate 130. The sliding rod 127 includes a smooth rod portion that mates with the groove 131, with threaded rods at both ends. Each nut 128 mates with a corresponding threaded rod, thereby adjusting the position of the nut 128 to adjust the clearance between the connecting rod 125 and the first mounting plate 130.

[0029] See Figures 1 to 3 Furthermore, two limiting plates 102 are spaced apart along the height direction between the two first side frames. The gathering bar 121 rotates between the two limiting plates 102, and one side of each cutter 200 faces the corresponding limiting plate 102, so that the cutter 200 can cooperate with the limiting plate 102 to better cut the leaves and roots of the scallion seedlings.

[0030] See Figures 1 to 3 Furthermore, a rectangular frame 210 is connected to one side of each of the two cutters 200, and a push plate 211 is connected between the two rectangular frames 210. The second driving mechanism is a cylinder 220 mounted on the frame 100, with the telescopic end of the cylinder 220 connected to the push plate 211. Specifically, the cylinder 220 drives the push plate 211 to move, thereby causing the two cutters 200 to move synchronously in the horizontal direction. It can be understood that the cylinder 220 is a bidirectional cylinder 220, and the air supply line of the bidirectional cylinder 220 is equipped with a reversing valve. The control module is electrically connected to the reversing valve, thereby changing the air supply direction through the reversing valve, so that the bidirectional cylinder 220 drives the push plate 211 to move reciprocally.

[0031] See Figures 1 to 3 Furthermore, the frame 100 includes two opposing second side frames, the two second side frames are connected to a second mounting plate 103, and the cylinder 220 is disposed on the second mounting plate 103, thereby using the second mounting plate 103 to provide the mounting position for the cylinder 220.

[0032] See Figures 1 to 3Furthermore, the second side frame includes two horizontally arranged crossbars 104. The two lower crossbars 104, together with the second mounting plate 103, define a material discharge channel. A brush 105 is arranged between the two upper crossbars 104, and the brush 105 is used to abut against the upper cutter 200. Specifically, a collection box is placed below the material discharge channel, the cutter 200 has a flat structure, and the brush 105 is located in the middle of the material discharge channel. After the cutter 200 cuts the leaves of the scallion seedlings, the leaves fall onto the upper surface of the cutter 200. The cutter 200 returns to the position of the brush 105, and the brush 105 pushes the leaves into the material discharge channel, thereby collecting the cut leaves and reducing the difficulty of subsequent manual cleaning of the cut leaves.

[0033] See Figure 3 Furthermore, the gathering strip 121 has an arc-shaped structure, and an elastic layer is provided on the inner side wall of the gathering strip 121. This elastic layer cushions the falling scallion seedlings, which helps to reduce damage to the scallion seedlings. The multiple gathering strips 121 are spaced apart, which helps to expose the roots of the scallion seedlings for subsequent cutting.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
