Description

Technical Field

[0001] The utility model relates to the technical field of seedling separation and transplanting, and more specifically, to a high-speed motion module for seedling separation and transplanting. Background Art

[0002] During breeding, the seeds are first planted in a seedling tray, which is equipped with several seedling troughs of uniform size. The seeds are sown in the seedling troughs until roots grow. During this process, the rhizomes will tightly bind the soil matrix in the seedling troughs. Because the distance between adjacent seedling troughs in the breeding tray is small, after breeding, they need to be replanted with roots and soil in a larger hole tray. This operation is called transplanting. Common applications include fruit and vegetable seedlings, flowers, Chinese medicinal materials, etc. The purpose of transplanting is to ensure appropriate space to promote plant rooting and growth.

[0003] In large-scale planting scenarios, transplanting work is often completed by transplanting robots. The specific process is that the raw seedlings are transported to the processing area by the raw seedling conveyor belt. The mobile module drives the seedling retrieval module to the top of the seedling tray, grabs the entire row of seedlings at a time, and then moves to the top of the planting tray and plants the raw seedlings in the planting tray.

[0004] During the transplanting process, the motion module is a critical component, which drives the transplanter to reciprocate between the seedling tray and the planting hole tray. The stability of the motion module is high. At the same time, because the seedling trough is relatively small and compact, the operation accuracy of the motion module is high. The existing motion module is difficult to balance high stability and high precision. During the movement process, it is easy to cause the matrix to disperse and the seedlings to fall due to poor stability, and the clamping is not firm due to inaccurate position.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0024] like Figure 1-2 As shown, the transplanting work is completed by the transplanting equipment, and the raw seedlings are transported to the processing area by the conveyor line 8. The movement module in this scheme drives the seedling picking module 11 to the top of the seedling tray 9, grabs the whole row of seedlings at a time, moves to the top of the planting hole tray 10 after the grabbing is completed, and plants the raw seedlings in the planting hole tray 10.

[0025] like Figure 3-5 As shown, the technical solution of the utility model provides a high-speed motion module for seedling transplanting, including a translation guide rail assembly, a mounting plate 3, a translation drive assembly 4, two sets of lifting assemblies 6 and a calibration assembly 5.

[0026] The translation guide rail assembly includes a middle guide rail 1 and two outer guide rails 2 symmetrically arranged on both sides of the middle guide rail 1. The mounting plate 3 is slidably connected to the middle guide rail 1 and the outer guide rails 2. The middle guide rail 1 and the two outer guide rails 2 form two moving spaces. The lifting assembly 6 is arranged on the mounting plate 3, and the two groups of the lifting assemblies 6 are respectively located in the two moving spaces.

[0027] In the above scheme, the guide rail assembly is configured as three parallel guide rails, and the lifting assembly 6 is configured on the mounting plate 3. The horizontal movement of the lifting assembly 6 is indirectly realized by driving the mounting plate 3 to move through the translation drive assembly 4. The mounting plate 3 is located above the guide rail assembly and supported by the guide rail assembly. The purpose of horizontal movement is to enable the lifting assembly 6 to flexibly reach the top of the breeding tray and the planting hole tray. The seedling removal module is configured on the lifting assembly 6. When the horizontal displacement is in place, the lifting assembly 6 drives the seedling removal module to move downward, and then the seedling removal module clamps the raw material seedlings in the seedling tray, and then the motion module drives the seedling removal module to move the raw material seedlings to the planting hole tray.

[0028] This solution sets a middle rail 1 and two outer rails 2. The three rails support the mounting plate 3 at the same time to ensure that the lifting assembly 6 moves smoothly during horizontal movement. At the same time, the lifting assembly 6 is set into two groups to achieve a stable connection with the seedling removal module to meet the weight requirements. The high stability of this motion module improves the operating efficiency of the motion module, and the translation rate can achieve 1m / s, thereby improving the transplanting efficiency.

[0029] The translation drive assembly 4 includes a translation motor 41, a translation gear 42 disposed at the output end of the translation motor 41, and a translation rack 43 disposed at one side of the intermediate guide rail 1, wherein the translation gear 42 is meshed with the translation rack 43. The translation motor 41 drives the translation gear 42 to rotate, and since the translation gear 42 is meshed with the translation rack 43, the mounting plate 3 is moved on the guide rail assembly, thereby realizing the movement of the lifting assembly 6.

[0030] The translation motor 41 is arranged on the mounting plate 3 , and the end portion thereof penetrates through the mounting plate 3 . The translation motor 41 is installed upside down, and the penetration design makes the overall structure compact, and the translation motor 41 is firmly fixed.

[0031] During the translation process, due to reasons such as jamming or slipping, accurate displacement cannot be achieved, resulting in certain mechanical errors. For this reason, a calibration component 5 is provided to calibrate the translation. The calibration component 5 moves horizontally synchronously with one of the lifting components 6, and is in rolling contact with one of the outer guide rails 2. The calibration component 5 includes a mounting bracket 51, a synchronizer 52 disposed on the mounting bracket 51, and a synchronous rotating disk 53 connected to the central axis of the synchronizer 52, and the side of the synchronous rotating disk 53 is in rolling contact with the side of one of the outer guide rails 2.

[0032] In the above scheme, during the horizontal movement of the lifting assembly 6, the synchronous turntable 53 contacts the outer guide rail 2 and rotates during the movement. During the rotation, the synchronizer 52 transmits a real-time pulse signal to the system, which is compared with the pulse signal of the translation motor 41. For example, if the pulse signal recorded by the synchronizer 52 is 10 and the pulse signal of the translation motor 41 is 9, the translation motor 41 will add another pulse signal consistent with the synchronizer 52. Real-time calibration during the movement can improve the translation accuracy, ensure that the seedling assembly can correctly reach the top of the seedling tray and the planting hole tray, and ensure the accuracy of the clamping position.

[0033] A protective ring 54 is arranged on the outside of the turntable and is made of rubber to avoid wear on the outer guide rail 2 .

[0034] The lifting assembly 6 includes a lifting frame 61, a lifting drive 62 disposed on the lifting frame 61, and a lifting mounting plate 63 connected to the lifting drive 62, wherein the lifting mounting plate 63 is slidably connected to the lifting frame 61. The lifting drive 62 is composed of a lifting motor, a screw rod, a screw rod slider and other components, and is driven by the lifting drive 62 to realize the up and down movement of the lifting frame 61.

[0035] The present solution further comprises a plurality of photoelectric switches 7 arranged on one of the outer guide rails 2, and the photoelectric switches 7 can locate the operating position of the lifting assembly.

[0036] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
