Description

Technical Field

[0001] The invention relates to a vegetable leaf transplanter. Background Art

[0002] Leafy vegetables are an indispensable food in people's daily life. Currently, more than 60% of vegetables are grown by seedling transplanting. Affected by the existing transplanting technology, transplanting operations are mainly done manually. Due to the continuous tightening of land resources for growing vegetables and the requirements of traditional agronomic planting, most leafy vegetables are planted in a high-density manner, that is, the spacing between plants and rows is relatively small. High-density planting has led to a sharp increase in the amount of transplanting operations. With the advancement of agricultural mechanization, the traditional manual transplanting mode can no longer meet the needs of high-density vegetable planting. The development of high-speed leafy vegetable transplanters to improve the speed and efficiency of leafy vegetable transplanting is of great significance to the cultivation and development of high-density vegetables in my country. Summary of the invention

[0003] The object of the present invention is to provide a leafy vegetable transfer machine which can quickly transfer leafy vegetable seedlings in a densely planted planting tray to a sparsely planted planting tray, thereby improving the leafy vegetable transplanting speed and efficiency.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: The lifting of the ... The back of the plate is installed on the nut seat of the horizontal linear module and the slide rail of the linear guide rail. Two linear optical axis slide rails and a rodless cylinder are installed in front of the base plate of the equalizing mechanism. The rodless cylinder is located between the two linear optical axis slide rails. The seedling picker is fixed to the slider of the linear optical axis slide rail. The rightmost seedling picker is fixed and the leftmost seedling picker is fixed to the slider of the rodless cylinder. The tops of several seedling pickers are connected in series by nylon belts. The seedling picker includes a seedling picker mounting plate, a vertical guide rail, and a gripper. A hand cylinder base, a lifting cylinder, a pin assembly, and a seedling pushing assembly. A vertical slide rail is installed at the lower part of the seedling extractor mounting plate, and one end of the drag chain is installed at the upper end. The vertical plate of the gripper cylinder base is installed on the slider of the vertical guide rail, and a vertical connecting plate is installed on the upper part of the vertical plate. The top of the vertical connecting plate is connected to the other end of the drag chain. The bottom of the lifting cylinder is installed on the top plate of the seedling extractor mounting plate. The piston rod end of the lifting cylinder, the seedling pushing assembly, and the pin assembly are installed on the bottom plate of the gripper cylinder base. During transplanting, the bottom conveyor belt transports the two specifications of planting trays to the right respectively, and the slider of the rodless cylinder moves to the far right, and also drives the first seedling picker on the left to move to the far right. At this time, the four seedling pickers are close together and the spacing between seedlings in the dense planting tray is equal. The horizontal linear module and the vertical linear module move, and the pins of the pin assembly are aligned with the holes of the dense planting tray. The lifting cylinder extends, and the base of the gripper cylinder is pushed down. At the same time, the cylinder of the pin assembly extends, and the pin is inserted into the sponge of the planting cup of the planting tray. Then the lifting cylinder is lifted, together with the planting cup and the leaves in the cup. The seedlings are pulled out of the planting tray, and the horizontal linear module and the longitudinal linear module work together to move the planting cup to the top of the thinning planting tray. The slider of the rodless cylinder moves to the left to separate the seedling pickers that are close together. The separation distance is the spacing between the holes in the thinning planting tray. After the planting cups are aligned with the holes in the thinning planting tray, the lifting cylinder extends again to place the planting cups in the holes in the thinning planting tray. At this time, the seedling pushing cylinder extends, and the seedling pushing needle of the seedling pushing assembly is pinned to the surface of the planting cup. The cylinder of the pin assembly retracts, and the cylinder of the seedling pushing assembly and the lifting cylinder also retract to complete a leafy vegetable transplant process.

[0005] The seedling extractor is assembled with four seedling extractors, each of which is equipped with two pin assemblies. The pin assembly includes a cylinder A and a pin. The pin is installed on the rod head of cylinder A. The cylinder barrel of cylinder A is fixed to the bottom plate of the gripper cylinder base, and the two pin assemblies are arranged obliquely. The seedling pushing assembly includes a cylinder B and a seedling pushing needle. The cylinder barrel of cylinder B is fixed to the bottom plate of the gripper cylinder base and is also arranged obliquely. A seedling pushing needle is installed on the rod head of cylinder B. The top of the seedling pushing needle is flat and has no tip. Its length is shorter than that of the pin. The center extension lines of cylinder A and cylinder B intersect at one point.

[0006] The frame is a frame structure, including a base, a support plate and casters. The base is the main body of the frame. The support plate is located in the upper part of the base. The casters are fixed to the base legs. The connection between the support plate and the base is a long hole. The horizontality of the support plate can be adjusted during installation to ensure the horizontality of the linear module on the upper part of the support plate.

[0007] Every time the lead screw of the transverse linear module rotates one circle, the nut seat of the transverse linear module moves 2 cm, and every time the lead screw of the longitudinal linear module rotates one circle, the nut seat of the longitudinal linear module moves 1 cm.

[0008] When the seedling pickers are close together, the width between the seedling pickers is 48 mm, which is equal to the spacing between the holes of the dense planting tray, and the pins are just aligned with the holes of the dense planting tray; when the seedling pickers straighten the nylon belts, the spacing between the seedling pickers is 192 mm, which is equal to the spacing between the holes of the sparse planting tray, and the pins are just aligned with the holes of the sparse planting tray.

[0009] The beneficial effects of the present invention are as follows: the connection between the support plate and the base is a long hole, and the horizontality of the support plate can be adjusted during installation, thereby ensuring the levelness of the linear module on the upper part of the support plate. For every rotation of the lead screw of the transverse linear module, the nut seat of the transverse linear module moves 2 cm, and for every rotation of the lead screw of the longitudinal linear module, the nut seat of the longitudinal linear module moves 1 cm. The lead screw is driven by a servo motor, and both accuracy and speed can be taken into account. The width of the seedling extractor is 48 mm, which is equal to the spacing between the holes of the dense planting tray. When the seedling extractors are closed together, the pins are aligned with the holes of the dense planting tray. When the seedling extractor straightens the nylon belt, the spacing between the seedling extractors is 192 mm, which is equal to the spacing between the holes of the sparse planting tray, and the pins are aligned with the holes of the sparse planting tray.
