Description

Technical Field

[0001] The present application relates to the field of agricultural equipment, and in particular to a guide rail docking device for a seedling bed conveying AGV. Background Art

[0002] With the rapid development of automation technology, intelligent equipment has gradually been introduced into the agricultural field to improve production efficiency and reduce costs. The seedbed conveying system is a common equipment in modern agricultural production. Among them, the seedbed conveying AGV (automatic guided vehicle) is one of the key equipment in automated agricultural production. It is used to transport the planted seedbeds from the nursery room or nursery area to other production links, such as seedling cultivation or planting areas.

[0003] The guide rail docking device of the seedbed conveying AGV is used to dock the seedbed conveying AGV with the seedbed conveying line when taking and placing the seedbed. After the guide rails are docked, they can not only limit the movement of the AGV body, but also ensure that the seedbed maintains a stable trajectory during the process of taking and placing the seedbed. The guide rail docking device of the traditional seedbed conveying AGV includes guide rails, transmission components, sensors and control systems. The guide rails, transmission components, sensors and control systems are all installed on the AGV body. The transmission device is responsible for driving the movement and docking of the guide rails. The sensor is used to detect the position of the seedbed and the state of the guide rails. The control system controls the transmission device to achieve docking according to the feedback information from the sensor.

[0004] Although the existing guide rail docking device of the seedling bed conveying AGV has improved the efficiency and accuracy of seedling bed conveying to a certain extent, during the process of taking and placing the seedling bed, the transmission assembly drives the guide rail to extend and dock with the seedling bed conveyor line. During this period, the seedling bed is mainly supported by the guide rail. Therefore, the guide rail is the main force-bearing part. Over time, the guide rail is very easy to deform, which will cause the stability of the guide rail to deteriorate, greatly affecting the safe transportation of the seedling bed.

In the embodiment of the present application, two groups of guide components 1 are arranged along the length direction of the AGV body, and are symmetrically arranged on both sides of the length direction of the AGV body.

[0047] The guide assembly 1 includes a guide rail 11, a sleeve 12 and a driving member 13. The sleeve 12 is fixedly connected to the AGV body. One end of the guide rail 11 is slidably arranged in the sleeve 12, and the other end of the guide rail 11 extends out of the sleeve 12. A connecting plate 112 is fixedly arranged at one end of the guide rail 11 extending out of the sleeve 12, and the end face of the guide rail 11 is chamfered.

[0048] A plurality of avoidance grooves 111 are provided on the guide rail 11 along the axial direction, and a roller 14 is arranged in the avoidance groove 111. The roller 14 is rotatably connected to the guide rail 11, and the roller 14 slightly protrudes from the outer peripheral wall of the guide rail 11. A strip groove is provided on the inner wall of the corresponding sleeve 12 for avoiding the roller 14 when the guide rail 11 retracts, so as to prevent interference between the roller 14 and the sleeve 12, which would cause the guide rail 11 to fail to retract normally.

[0054] refer to Figure 5 , Figure 6 and Figure 7 The support assembly 2 includes a storage rod 21 and a support rod 22. The storage rod 21 is slidably disposed on the supporting portion 311 and is fixedly connected to the slider 332. The support rod 22 is rotatably connected to the storage rod 21. When the storage rod 21 is extended, the support rod 22 can automatically open and support the guide rail 11. When the storage rod 21 is retracted, the support rod 22 can automatically fold and be stored on the AGV body together with the storage rod 21. The specific connection relationship is as follows:

[0055] A receiving groove 214 is provided on the storage rod 21, and a locking pin 211 and a spring 212 are provided on the storage rod 21. A mounting groove 213 is provided on the storage rod 21, and the locking pin 211 is slidably arranged in the mounting groove 213. One end of the spring 212 is fixedly connected to one end of the locking pin 211, and the other end of the spring 212 is fixedly arranged on the inner wall of the mounting groove 213.

[0056] The support rod 22 is arranged in the accommodating groove 214, and a rotating shaft 224 is fixedly provided at one end of the support rod 22 close to the slider 332. The support rod 22 is rotatably connected to the storage rod 21 through the rotating shaft 224. The other end of the support rod 22 is a movable end. A supporting portion 223 is fixedly provided on the end face of the support rod 22 close to the rotating shaft 224. A supporting wheel 23 is provided on the supporting portion 223.

The support rod 22 can play a supporting role when the guide rail 11 is subjected to force, and the support wheel 23 can reduce the friction between the support rod 22 and the guide rail 11.

[0057] When the storage rod 21 extends out of the AGV body under the action of the screw rod 331, the support rod 22 will automatically open to a vertical state under the action of gravity. At this time, the locking pin 211 can be plugged into the locking groove 221 under the action of the spring 212 to limit the rotation of the support rod 22; when the storage rod 21 is retracted inward, the support rod 22 abuts against the side of the AGV body, forcing the locking pin 211 to separate from the locking groove 221, and the support rod 22 can fold itself until the support rod 22 is completely stored in the storage rod 21 and is retracted into the AGV body together with the storage rod 21. At this time, the storage rod 21 and the support rod 22 are both abutted against the supporting portion 311.

[0058] The implementation principle of the guide rail docking device of the seedbed conveying AGV in the embodiment of the present application is:

[0059] In this embodiment, when the guide rail docking device needs to dock the guide rail 11, the AGV body is first controlled to move until the AGV body is aligned with the seedling bed conveyor line. Then the driving member 13 is controlled to drive the guide rail 11 to plug with the docking member 42, and then the motor 32 is controlled to drive the storage rod 21 to extend. The support rod 22 will automatically open to a vertical state under the action of gravity. The support rod 22 can support the guide rail 11, and the storage rod 21 can overlap the supporting portion 411.

[0060] When the guide rail 11 is used up, the control motor 32 drives the storage rod 21 to be retracted, and the support rod 22 will abut against the side of the AGV body. The support rod 22 can fold itself and be retracted into the AGV body together with the storage rod 21. Then the control driving member 13 drives the guide rail 11 to retract the sleeve 12, and finally controls the movement of the AGV body.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
