Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a seedling-picking mechanical claw used in vegetable transplanters. Background Technology

[0002] The fully automatic vegetable transplanter is a key piece of equipment for achieving automation in vegetable planting, and the seedling-grabbing mechanical claw is its core component. The seedling-grabbing principle, structure, and movement trajectory of the claw directly affect the area of ​​the seedling being grasped, the degree of damage to the seedling, and thus the success rate of seedling removal and even the overall transplanting quality of the machine. Currently available seedling-grabbing mechanical claws are large and complex in structure, easily leading to errors or damage to seedlings during use. This not only makes equipment maintenance time-consuming and labor-intensive but may also damage seedlings, potentially impacting crop yield in severe cases. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing seedling extraction technologies and provide a simple, reliable, stable, efficient, and protective mechanical claw for seedling extraction.

[0004] This utility model provides the following technical solution: a seedling picking mechanical claw for a vegetable transplanter, characterized in that: it includes a seedling needle telescopic drive unit, a seedling pusher plate fixing seat, a connector, a seedling needle base, and seedling needles. The seedling pusher plate fixing seat is fixed to the seedling needle telescopic drive unit by screws. The connector is connected to the push rod of the seedling needle telescopic drive unit by screws. The connector has two pin holes. The seedling needle base has pin holes. The two seedling needle bases are symmetrically hinged to the connector by pins passing through the pin holes. The seedling needle base has two circular holes with depth and two threaded holes at corresponding positions. Four seedling needles are respectively inserted into the circular holes of the two seedling needle bases and are fixedly connected to the two seedling needle bases by set screws through the threaded holes. The seedling needles pass through the circular holes on the plane of the seedling pusher plate fixing seat to constrain their movement trajectory.

[0005] Furthermore, the needle telescopic drive unit can be any one of a cylinder, electromagnetic push rod, or linear motor capable of performing telescopic actions.

[0006] Furthermore, the seedling pusher plate fixing seat is made of sheet metal and has three planes and one inclined surface, specifically including four surfaces: plane one, plane two, inclined surface, and plane three. The spacing between the circular holes of adjacent seedling needles fixed on the left and right seedling needle bases should be less than the spacing between the left and right pin holes of the connector.

[0007] Furthermore, the seedling needle is movably connected to the round hole on the seedling pusher plate fixing seat that restricts its movement, maintaining a clearance fit.

[0008] When taking seedlings, the push rod of the seedling needle extension and retraction drive unit extends, driving the connecting piece to move forward. Due to the tight connection between the seedling needle base and the seedling needle, under the constraint of the first round hole at the front of the seedling pusher plate fixing seat, the seedling needle base swings inward while moving forward, the seedling needle extends and the distance between the needle tips continuously decreases until it clamps the vegetable tray seedling substrate, thus completing the seedling taking.

[0009] When seedlings are placed, the push rod of the seedling needle extension and retraction drive unit retracts, causing the connecting piece to move backward. As the seedling needle base moves backward, it swings outward. The seedling needle retracts and the distance between the needle tips continuously increases, thus completing the seedling placement.

[0010] The beneficial effects of this utility model are:

[0011] This utility model has a simple and compact structure, low requirements for the processing of parts, and occupies little space. It has an effective seedling needle gripping path, can adapt to the automatic seedling picking and transplanting requirements of different vegetable plug seedlings, and has strong applicability. The design of the seedling pusher plate fixing seat can greatly avoid interference between the vegetable plug seedlings and the seedling picking mechanism during seedling picking, and avoid damage to the seedlings.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figure 1-4A seedling-grabbing mechanical claw for a vegetable transplanter includes a seedling needle telescopic drive unit 1, a seedling pusher plate fixing seat 2, a connector 3, a seedling needle base 4, and seedling needles 5. The seedling pusher plate fixing seat 2 is fixed to the seedling needle telescopic drive unit 1 by screws. The connector 3 is connected to the push rod of the seedling needle telescopic drive unit 1 by screws. The connector 3 has two pin holes. The seedling needle base 4 has a pin hole 4-1. The two seedling needle bases 4 are symmetrically hinged to the connector 3 by pins passing through the pin holes 4-1. The seedling needle base 4 has two round holes 4-3 with depth and two threaded holes 4-2 at corresponding positions. The four seedling needles 5 are respectively inserted into the round holes 4-3 of the two seedling needle bases 4 and are fixedly connected to the two seedling needle bases 4 by set screws through the threaded holes 4-2. The seedling needles 5 pass through the round holes 2-5 opened on the plane 2-4 of the seedling pusher plate fixing seat to constrain their movement trajectory.

[0019] The needle telescopic drive unit 1 can be any one of a cylinder, electromagnetic push rod, or linear motor capable of performing telescopic actions.

[0020] The seedling pusher plate fixing seat 2 is made of sheet metal and is used to constrain the distance between the round holes 2-5 of adjacent seedling needles fixed on the two seedling needle bases 4 to be less than the distance between the left and right pin holes of the connector 3. The inclined surface 2-2 is used to reduce collision with vegetable seedlings. The plane 2-2, the inclined surface 2-3 and the plane 2-4 are used together to prevent the stems and leaves of vegetable seedlings from entering other seedling picking mechanisms when picking or placing seedlings, so as not to interfere with the normal seedling picking and placing operations.

[0021] The seedling needle 5 is movably connected to the round hole 2-5 on the seedling pusher plate fixing seat 2 that restricts its movement, maintaining a clearance fit.

[0022] In practical use, such as Figure 4 First, the seedling-picking mechanical claw is installed on the corresponding automatic transplanter's seedling-picking mechanism. The installation angle and height of the claw are adjusted according to the different types of vegetable seedlings and the specifications of the seedling trays to prevent unnecessary interference or collision between the claw and the seedlings during operation. During seedling picking, the push rod of the seedling needle extension drive unit 1 extends, driving the connecting piece 3 forward. Due to the tight connection between the seedling needle base 4 and the seedling needle 5, and constrained by the front circular hole 2-5 of the seedling pusher plate fixing seat 2, the seedling needle base 4 swings inward while moving forward. The seedling needle 5 extends, and the distance between its needle tips continuously decreases until it clamps the vegetable tray seedling substrate, completing the seedling picking process.

[0023] When seedlings are placed, the push rod of the seedling needle extension and retraction drive unit 1 retracts, driving the connecting piece 3 to move backward. The seedling needle base 4 swings outward while moving backward, and the seedling needle 5 retracts and the distance between the needle tips continuously increases, thus completing the seedling placement.

[0024] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
