Description

Technical Field

[0001] This utility model relates to transplanting machines, and in particular to a seedling feeding device and transplanting machine with a rotation control mechanism. Background Technology

[0002] Currently, seedling feeding devices are generally either offset or central. While offset seedling feeding structures are relatively simple, the seedling substrate is not located in the center of the feeding device during feeding, causing the seedling to come into contact with the feeding tube during the descent, which affects the seedling's landing posture. Existing central seedling feeding devices have a large trigger structure, which affects the tight layout of the seedling tubes. Alternatively, the opening and closing structure is designed to slide, resulting in a shorter service life. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a seedling feeding device and transplanter, which uses a simple rotary control mechanism to control the opening or closing of the opening and closing mechanism, thus overcoming one or more defects in the existing technology.

[0004] To achieve the above objectives, this utility model provides a seedling feeding device comprising: a seedling feeding cylinder; an opening and closing mechanism disposed at the bottom end of the seedling feeding cylinder; and a rotation control mechanism mounted on the seedling feeding cylinder and connected to the opening and closing mechanism. The rotation control mechanism includes a rotating plate, a roller, and a drive arm. The rotating plate includes a rotating body, a first mounting hole located at the center of the rotating body, and a second mounting hole and a third mounting hole surrounding the first mounting hole. The first mounting hole is mounted on the shaft of the seedling feeding cylinder and can rotate around the shaft. An elastic element is disposed within the first mounting hole, and the elastic element connects the seedling feeding cylinder and the rotating body. The second mounting hole connects to the roller, and the roller connects to an external power device. The third mounting hole connects to the drive arm, and the drive arm connects to the opening and closing mechanism.

[0005] The elastic element is a torsion spring, and the spring body of the torsion spring is disposed in the first mounting hole. The first long arm and the second long arm of the torsion spring are respectively connected to the rotating body and the seedling tube.

[0006] The bottom sides of the seedling tube are respectively equipped with a first bolt and a second bolt, and the second long arm of the torsion spring is connected to the first bolt or the second bolt.

[0007] The opening and closing mechanism includes a first opening and closing door and a second opening and closing door arranged opposite to each other; the driving arm includes a first connecting arm and a second connecting arm; the third mounting hole includes a fourth mounting hole and a fifth mounting hole, the fifth mounting hole being arranged opposite to the second mounting hole; the first connecting arm is connected to the first opening and closing door and the fourth mounting hole at both ends, and the second connecting arm is connected to the second opening and closing door and the fifth mounting hole at both ends.

[0008] The elastic element generates a force in a first rotational direction on the rotating plate, causing the rotating plate to drive the drive arm to close the opening and closing mechanism; the external power device generates a force in a second rotational direction on the roller, causing the roller to drive the rotating plate to rotate in the second rotational direction, thereby driving the drive arm to open the opening and closing mechanism; the first rotational direction is opposite to the second rotational direction.

[0009] The third mounting hole also includes a sixth mounting hole that is opposite to the fourth mounting hole; the two ends of the first connecting arm are respectively connected to the first opening and closing door and the fourth mounting hole, and the two ends of the second connecting arm are respectively connected to the second opening and closing door and the fifth mounting hole, or the two ends of the first connecting arm are respectively connected to the second opening and closing door and the sixth mounting hole, and the two ends of the second connecting arm are respectively connected to the first opening and closing door and the fifth mounting hole.

[0010] The bottom of the seedling tube is provided with a first mounting ear and a second mounting ear respectively. The first opening and closing door includes a first rolling ear, and the second opening and closing door includes a second rolling ear. The first bolt passes through the first mounting ear and the first rolling ear, so that the first opening and closing door rotates along the first bolt. The second bolt passes through the second mounting ear and the second rolling ear, so that the second opening and closing door rotates along the second bolt.

[0011] The first opening and closing door is provided with a protruding first connecting rod, and the second opening and closing door is provided with a protruding second connecting rod; the first connecting arm is connected to the first connecting rod, and the second connecting arm is connected to the second connecting rod, or the first connecting arm is connected to the second connecting rod, and the second connecting arm is connected to the first connecting rod.

[0060] like Figures 1 to 4 As shown, where, Figure 1 This is a perspective view of a seedling feeding device 1 provided in an embodiment of the present invention. Figure 2 This is a front view of the seedling feeding device 1. Figure 3 This is a side view of the seedling feeding device 1. Figure 4 This is a structural diagram of the rotation control mechanism and the opening and closing mechanism in the seedling feeding device 1.

[0061] The seedling feeding device 1 includes a seedling feeding cylinder 10, a rotation control mechanism 11, and an opening and closing mechanism 12. The opening and closing mechanism 12 is located at the bottom of the seedling feeding cylinder 10; the rotation control mechanism 11 is installed at the bottom of the seedling feeding cylinder 10 and connected to the opening and closing mechanism 12.

[0062] The seedling feeding cylinder 10 includes a first cylinder 100, a second cylinder 101, and a third cylinder 102 connected sequentially from bottom to top. The inner diameter of the first cylinder 100 is smaller than that of the third cylinder 102. The longitudinal section (i.e., axial section) of the second cylinder 101 is trapezoidal, and its inner diameter increases from bottom to top. The transverse section of the seedling feeding cylinder 10 is square. This structure, with its increasing inner diameter from bottom to top, facilitates seedling feeding and automatic centering, ensuring the seedlings automatically align with the center of the opening and closing mechanism 12.

[0063] The opening and closing mechanism 12 is duckbill-shaped and installed at the bottom end of the first cylinder 100. Specifically, the bottom sides of the first cylinder 100 are respectively provided with a first mounting ear 1000 and a second mounting ear 1001. The opening and closing mechanism 12 includes a first opening and closing door 120 and a second opening and closing door 121 arranged opposite to each other. The first opening and closing door 120 includes a first rolling ear 1200, and the second opening and closing door 121 includes a second rolling ear 1210. A first bolt 130 passes through the first mounting ear 1000 and the first rolling ear 1200, so that the first opening and closing door 120 is installed on the first cylinder 100, and the first opening and closing door 120 can rotate along the first bolt 130; a second bolt 131 passes through the second mounting ear 1001 and the second rolling ear 1210, so that the second opening and closing door 121 is installed on the first cylinder 100, and the second opening and closing door 121 can rotate along the second bolt 131. In this embodiment, the first mounting ear 1000, the second mounting ear 1001, the first coiled ear 1200, and the second coiled ear 1210 are all two symmetrical pieces. The first bolt 130 and the second bolt 131 are long bolts, which are respectively fixed to the first mounting ear 1000 and the second mounting ear 1001.

[0064] A rotation control mechanism 11 is mounted on the first surface 1002 of the first cylinder 100. The rotation control mechanism 11 includes a rotating plate 110, a roller 111, and a drive arm 112. The rotating plate 110 includes a rotating body 1100 and a first mounting hole 1101, a second mounting hole 1102, and a third mounting hole 1103 disposed on the rotating body 1100. The first mounting hole 1101 is located at the center of the rotating body 1100, and the second mounting hole 1102 and the third mounting hole 1103 are disposed around the first mounting hole 1101. The third mounting hole 1103 also includes a fifth mounting hole 1103b, a fourth mounting hole 1103a, and a sixth mounting hole 1103c disposed opposite to each other. The fifth mounting hole 1103b is disposed opposite to the second mounting hole 1102, and the sixth mounting hole 1103c serves as a spare mounting hole.

[0065] The first mounting hole 1101 is mounted on the rod shaft (not shown) of the first cylinder 100 via a detachable connector, such as a bolt 141, and the first mounting hole 1101 is rotatable around the rod shaft, which is perpendicular to the first surface 1002 of the first cylinder 100. An elastic element (e.g., a torsion spring 113) is provided inside the first mounting hole 1101, and the elastic element connects the seeding cylinder 10 and the rotating body 100; the second mounting hole 1102 is connected to the roller 111 via a detachable connector, such as a bolt 143, and the roller 111 is connected to an external power device (not shown); the third mounting hole 1103 is connected to the drive arm 112, and the drive arm 112 is connected to the opening and closing mechanism 12.

[0066] The drive arm 112 includes a first connecting arm 1120 and a second connecting arm 1121. The first connecting arm 1120 is connected to a first opening and closing door 120 and a fourth mounting hole 1103a at both ends, and the second connecting arm 1121 is connected to a second opening and closing door 121 and a fifth mounting hole 1103b at both ends.

[0067] Specifically, the first opening and closing door 120 is provided with a first connecting rod 1201 protruding from the first surface 1002, and the second opening and closing door 121 is provided with a second connecting rod 1211 protruding from the first surface 1002. The first connecting arm 1120 is connected to the first connecting rod 1201 by a detachable connector, such as a bolt 142, and the second connecting arm 1121 is connected to the second connecting rod 1211 by a detachable connector, such as a bolt 142.

[0068] The spring body 1130 of the torsion spring 113 is installed in the first mounting hole 1101. The first long arm (not shown) of the torsion spring 113 is inserted into the slot 1104 of the rotating body 1100, and the second long arm 1132 of the torsion spring 113 abuts against one of the first bolt 130 and the second bolt 131 (e.g., the second bolt 131). Thus, the torsion spring 113 always exerts a force in the first rotational direction (e.g., clockwise X1) on the rotating plate 110, causing the rotating plate 110 to drive the drive arm 112 to close the opening and closing mechanism 12. At this time, the seedling feeding device 1 is in a waiting state for seedlings to be received. When seedlings need to be fed, a force in the second rotational direction (e.g., counterclockwise X2) is generated on the roller 111 by an external power device, causing the roller 111 to drive the rotating plate 110 to rotate counterclockwise, thereby driving the drive arm 112 to open the opening and closing mechanism 12.

[0069] In some embodiments, the external power unit is, for example, an electric motor, mounted on the seedling cylinder 10 or on the transplanter where the seedling cylinder 10 is located. The electric motor is connected to the roller 111 via gears to drive its rotation. In other embodiments, the external power unit includes a trigger rod and a power source (e.g., a cylinder). The trigger rod triggers the roller 111 to rotate under the drive of the power source.

[0070] In this embodiment, when the roller 111 is not subjected to external force, the second long arm 1132 of the torsion spring 113 abuts against the lower part of the second bolt 131 (e.g., Figure 4 The first long arm is fixed at the slot 1104. The torsion spring 113 pulls the rotating plate 110, so that the rotating plate 110 is always subjected to a clockwise force X1. The first connecting arm 1120 connected to the rotating plate 110 pulls the first opening and closing door 120 closer to the middle (the middle of the first opening and closing door 120 and the second opening and closing door 121) through the first connecting rod 1201. The second connecting arm 121 connected to the rotating plate 110 pulls the second opening and closing door 121 closer to the middle through the second connecting rod 1211. The first opening and closing door 120 and the second opening and closing door 121 are closed. At this time, the seedling feeding device 1 is in the waiting state for receiving seedlings.

[0071] When the roller 111 is subjected to a counterclockwise force X2 from an external power device, and the counterclockwise force X2 is greater than the tension of the torsion spring 113, the roller 111 rotates counterclockwise. The roller 111 drives the rotating plate 110 to rotate counterclockwise. The rotating plate 110 drives the first connecting arm 1120 and the second connecting arm 1121 to move the first opening and closing door 120 and the second opening and closing door 121 to both sides respectively. The first opening and closing door 120 and the second opening and closing door 121 open, and the seedling (not shown in the figure) falls under the action of gravity, completing the seedling placement action.

[0072] In this embodiment, when the opening and closing mechanism 12 is in the closed state, the torsion spring 113 generates a force in the first rotational direction, which is a clockwise force X1. In another embodiment (not shown), the force generated by the torsion spring 113 in the first rotational direction can also be a counterclockwise force X2. Specifically, in another embodiment, the second long arm 1132 of the torsion spring 113 abuts against the lower part of the first bolt 130, the two ends of the first connecting arm 1120 are respectively connected to the sixth mounting hole 1103c and the second connecting rod 1211, the two ends of the second connecting arm 1120 are respectively connected to the fifth mounting hole 1103b and the first connecting rod 1201, the torsion spring 113 pulls the rotating plate 110, so that the rotating plate 110 is always under a counterclockwise force X2, at which time the first opening and closing door 120 and the second opening and closing door 121 are closed. When the roller 111 is subjected to a force in the second rotation direction by an external power device, which is a clockwise force X1, and the clockwise force X1 is greater than the tension of the torsion spring 113, the roller 111 rotates clockwise. The roller 111 drives the rotating plate 110 to rotate clockwise. The rotating plate 110 drives the first connecting arm 1120 and the second connecting arm 1121 to move the second opening and closing door 121 and the first opening and closing door 120 to both sides respectively, and the first opening and closing door 120 and the second opening and closing door 121 open.

[0073] Another embodiment of this utility model provides a transplanter equipped with the above-mentioned seedling feeding device 1.

[0074] In summary, the seedling feeding device 1 of this utility model uses a rotary control mechanism 11 to control the opening and closing of the opening and closing mechanism 12, which has a small triggering force and a fast opening speed, which is conducive to the falling of seedlings; the overall structure of the seedling feeding device 1 is simple and saves costs; the opening and closing mechanism 12 rotates to open and close, with low working resistance and long service life.
