Description

Technical Field

[0001] The invention relates to an automatic assembly system for a cultivation frame loaded with a plurality of transparent root cultivation containers, and in particular to a lifting system for transporting the cultivation frame between a conveyor belt and a multi-layer three-dimensional cultivation frame. Background Art

[0002] Crop phenotypes are determined by genes and the environment, including yield, disease resistance, insect resistance, quality, etc. Studying crop phenotypes is of great practical significance for increasing crop yields and ensuring future food security. High-throughput phenotypic research requires the use of new methods and technologies to interpret and understand the mysteries of plant physiology, and the use of new methods and technologies requires the use of auxiliary tools - new equipment and new instruments to complete a series of research work. Under indoor conditions, high-throughput handling and transfer of crop cultivation equipment is also an important aspect of high-throughput phenotypic research, which greatly reduces labor costs and saves resource space.

[0003] Under indoor conditions, devices related to crop cultivation and transportation have been studied. An automated shelf handling system places multiple layers of turnover boxes or containers on each shelf, and the gap between the top of each shelf turnover box and the bottom of the upper shelf is as small as possible to save storage space. The upper support and lower limit parts of the picking unit ensure that the transport cart does not interfere with each other during the handling process. CN106852262A discloses a multi-layer three-dimensional automated mobile seedling bed system, in which the mobile unit is driven by a wheel system mechanism to perform lifting and lowering movements, and stops at a designated position under the action of a sensor positioning device. The lifting platform device can automatically transfer and transport the seedling bed to a designated position. A mobile automated fruit and vegetable planting system uses an upper plate machine and a lower plate machine to carry out cultivation production. By using a culture tank with a smooth strip, the upper plate machine pushes the planting plate to move along the smooth strip. These device systems can realize automated handling and movement, and improve production efficiency to a certain extent. However, during the operation of the device, there is no corresponding buffer device to prevent collisions between components of the device during movement, and the stability and safety of the entire system cannot be guaranteed. There is no corresponding sensing device, and the movement speed of the device and the distance relative to the track cannot be accurately measured. Therefore, it is necessary to develop a high-throughput crop cultivation and transportation device with strong stability and high safety factor.

[0004] In the multi-layer stereoscopic automated mobile seedling bed system disclosed in CN106852262A, it is necessary to set a driving device supporting the single seedling bed on the cultivation unit, and set iron blocks at the front and rear ends of the single seedling bed. During operation, the iron block cooperates with the electromagnet on the lifting platform device, and the driving device drives the single seedling bed to move, so as to complete the transfer and transportation of the single seedling bed. Although the device system realizes automated transportation and movement, it has made significant changes to the multi-layer stereoscopic seedling bed frame and the single seedling bed, and has high requirements for the cultivation unit. It is necessary to set a driving device, parallel guide rails, a U-shaped shell arranged between the parallel guide rails, etc. on the cultivation unit of the multi-layer stereoscopic seedling bed frame, and it is necessary to set iron blocks at the front and rear ends of each single seedling bed. On the one hand, its large-scale use is limited, and on the other hand, a large amount of cost is increased. Summary of the invention

[0034] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention. The parts not mentioned in the present invention are all prior art.

[0035] The plant cultivation containers in the existing container cultivation technology mainly place the cultivation substrate directly into the transparent root cultivation container, and then place multiple transparent root cultivation containers in the cultivation frame for light-shading cultivation as a whole. In order to optimize the use of space, the use of multi-layer three-dimensional cultivation racks for placing cultivation frames is gradually becoming popular. During the growth process of the plants in the cultivation containers, it is necessary to study the plant phenotype, so it is necessary to obtain the plant root phenotypic information. The existing method for obtaining the plant root phenotypic information is mainly to image the roots of the plants in the transparent root cultivation containers. The cultivation frames on the multi-layer three-dimensional cultivation racks need to be moved to the imaging area to image the transparent root cultivation containers. After the transparent root cultivation containers are imaged, the cultivation frames loaded with multiple transparent root cultivation containers after imaging need to be moved back to the original placement area.

[0036] In view of the above situation, the present invention provides a lifting system, see Figure 1 and Figure 2 The system includes a cultivation frame 4 loaded with multiple transparent root cultivation containers; a lifting frame 1, which is arranged between a conveyor belt (not shown in the figure) and a multi-layer three-dimensional cultivation frame 13; a lifting frame 3, which is used to complete the movement between the cultivation frame 4 and the conveyor belt and drive the cultivation frame 4 to move up and down in the lifting frame 1; a lifting vehicle 2, which is used to transfer the cultivation frame 4 between the lifting frame 3 and the multi-layer three-dimensional cultivation frame 13; a walking mechanism 10, which is used to drive the lifting frame 1 and the lifting frame 3 to slide between the conveyor belt and the multi-layer three-dimensional cultivation frame along the width direction of the conveyor belt and the multi-layer three-dimensional cultivation frame 13.

[0037] Furthermore, two light rails 8 are arranged between the conveyor belt and the multi-layer three-dimensional cultivation rack, and the two light rails 8 extend along the width direction of the multi-layer three-dimensional cultivation rack 13 and are perpendicular to the conveyor belt; the walking mechanism 10 is slidably arranged on the two light rails 8, and buffers 11 are arranged at both ends of the two light rails 8 to prevent the walking mechanism 10 from colliding with the ends of the two light rails 8.

The speed limiter 9 is linked with the safety clamp (not shown in the figure) installed on the lifting frame 3. The speed limiter 9 monitors and controls the speed of the lifting frame 3 at any time. When the lifting frame 3 exceeds speed, runs out of control or the transmission chain breaks, the speed limiter 9 and the safety clamp (not shown in the figure) send a linkage action to stop the lifting frame 3 to prevent the risk of falling.
