Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural planting technology, in particular to a rice seedling production equipment. BACKGROUND

[0002] Rice is a genus of cereal crops, and the representative species is Oryza sativa. According to the seed saving method, rice is divided into conventional rice and hybrid rice. Rice is a direct economic crop. The harvested rice grains are called rice. An important step in rice cultivation is seedling raising, that is, cultivating rice seeds into rice seedlings. The traditional method of rice seedling raising is to soak the seeds until they start to sprout, and then manage the seedlings in the field. The field is easily compacted by rainwater, which prevents the rice seedlings from growing vigorously after germination. In order to save seed consumption, reduce production costs, and facilitate centralized management, rice seedlings are now mostly raised in seedling trays.

[0003] Currently, the traditional method of seedling raising is to grow germinated seeds in seedling trays, and then lay the seedling trays flat on the ground of a greenhouse. Due to the limited area of the greenhouse floor, workers use seedling racks for seedling raising. The seedling racks can raise seedlings in multiple layers from top to bottom, improving space utilization. However, the upper seedling racks can block the lower seedling racks, preventing the rice seedlings in the lower seedling racks from absorbing sufficient sunlight and affecting their normal growth. SUMMARY

Before rice seedling culture, the following operations should be performed on the seeds: seed soaking treatment: soaking the seeds in appropriate warm water to promote germination speed; germination treatment: placing the seeds in wet gauze or straw to make the seeds germinate gradually; and finally, uniformly sowing the seeds on the seedling tray; the bearing column 1 is erected on the ground, the bearing column 1 is installed with a plurality of seedling assemblies 10 from top to bottom at equal intervals, wherein the seedling assembly 10 is composed of a first seedling plate 14 and a second seedling plate 15, the inner side of the first seedling plate 14 is provided with a first opening for placing the second seedling plate 15, the middle part of the second seedling plate 15 is provided with a second opening, and the bearing column 1 can pass through the second opening; the first driving rod 2 is perpendicular to the horizontal plane and passes through a plurality of first seedling plates 14, the first driving rod 2 is in threaded cooperation with a plurality of first seedling plates 14, one end of the first driving rod 2 is connected with the first driving motor 4, a first placing groove for placing the first driving motor 4 can be formed in the ground, the guide rod 3 is perpendicular to the horizontal plane and passes through a plurality of first seedling plates 14, the first driving motor 4 can control the first driving rod 2 to rotate, and after the first driving rod 2 rotates, the first driving rod 2 is in threaded cooperation with a plurality of first seedling plates 14, so that a plurality of first seedling plates 14 move up and down simultaneously; the second driving rod 5 is perpendicular to the horizontal plane and passes through a plurality of second seedling plates 15, the second driving rod 5 is in threaded cooperation with a plurality of second seedling plates 15, one end of the second driving rod 5 is connected with the second driving motor 6, a second placing groove for placing the second driving motor 6 can be formed in the ground, the second driving motor 6 can control the second driving rod 5 to rotate, and after the second driving rod 5 rotates, the second driving rod 5 is in threaded cooperation with a plurality of second seedling plates 15, so that a plurality of second seedling plates 15 move up and down simultaneously; specifically, the staff uniformly plants rice seeds on the first seedling plate 14 and the second seedling plate 15, the bearing column 1 is installed with a plurality of seedling assemblies 10 from top to bottom, which greatly saves the planting area compared with laying rice seeds flat on the ground, and attention should be paid to the temperature in the greenhouse during the seedling process, and the staff also needs to water each seedling assembly 10 in time to ensure that the rice seeds on each seedling assembly 10 can grow normally, but due to the structure of the seedling assembly 10 arranged in multiple layers from top to bottom, the upper seedling assembly 10 will block the lower seedling assembly 10, which will cause the rice seeds in the lower seedling assembly 10 to be unable to receive sufficient light, affecting their normal growth.At this time, the staff can start the first drive motor 4 and the second drive motor 6, control the first drive rod 2 and the second drive rod 5 to rotate, the first drive rod 2 rotates and drives the plurality of first seedling plates 14 to move downwards, the second drive rod 5 rotates and drives the plurality of second seedling plates 15 to rotate upwards (the first seedling plate 14 and the second seedling plate 15 of the same seedling assembly 10 are separated), so that the plurality of second seedling plates 15 are located on the upper side of the supporting column 1, and the plurality of first seedling plates 14 are located on the lower side of the supporting column 1; the area of the second seedling plate 15 is smaller (the second seedling plate 15 can be in the form of a ring), and the rice seeds planted on the second seedling plate 15 are located on the edge of the second seedling plate 15. The high-altitude light can be obliquely incident into the edge of the next layer of second seedling plate 15 from the upper layer of second seedling plate 15, so that the rice seeds on the second seedling plate 15 can all receive sufficient light. Similarly, the high-altitude light can be obliquely incident into the edge of the next layer of first seedling plate 14 from the upper layer of first seedling plate 14, so that the rice seeds on the first seedling plate 14 can all receive sufficient light. After receiving sufficient light, the first seedling plate 14 and the second seedling plate 15 of the same seedling assembly 10 can be combined, which is convenient for the subsequent management work of the staff.

[0025] In the present embodiment, the temperature in the greenhouse needs to be adjusted to a suitable temperature during rice seedling cultivation, and then watering is performed in each seedling assembly 10 at regular intervals. In addition, the staff can also move the first seedling plate 14 to the lower side of the supporting column 1 and move the second seedling plate 15 to the upper side of the supporting column 1, so that the rice seeds on the first seedling plate 14 and the second seedling plate 15 can receive sufficient light and ensure the normal growth of the rice seeds. The staff can also control the first drive motor 4 and the second drive motor 6 to rotate at the same speed and in the same direction, so that all the seedling assemblies 10 move downwards as a whole. After the seedling assemblies 10 move downwards, the height is reduced, which is convenient for the staff to manage the rice seeds on the seedling assemblies 10 without the need for lifting tools.

[0026] Further, in the present application, the lower side of the first drive rod 2 is provided with a first smooth section 7 matched with the first seedling plate 14, and an elastic member is connected between the adjacent two first seedling plates 14.

[0027] In the embodiment, the rice seedlings are cultivated in the rice seedling cultivation period, and the weeds, diseases and insect pests are controlled in time to ensure the healthy growth of the seedlings. The staff needs to lower the plurality of seedling cultivation assemblies 10 to a suitable height at any time, so as to facilitate the observation of the condition of the rice seeds on each seedling cultivation assembly 10. During the downward movement of the plurality of first seedling plates 14, when the lowermost first seedling plate 14 moves to the first smooth section 7, the lowermost first seedling plate 14 falls freely downward. After the lowermost first seedling plate 14 moves to a certain distance, the elastic member between the lowermost first seedling plate 14 and the second last first seedling plate 14 limits the lowermost first seedling plate 14 (the above-mentioned elastic member is elongated). When the uppermost first seedling plate 14 just moves to the first smooth section 7, the lowermost first seedling plate 14 just falls into the ground, and the elastic member between the adjacent two first seedling plates 14 is compressed, so as to reduce the distance between the adjacent two first seedling plates 14 and the height of the plurality of first seedling plates 14, thereby facilitating the management of each layer of first seedling plate 14 by the staff. Moreover, the elastic member is arranged between the adjacent two first seedling plates 14, so as to avoid the collision between the adjacent two first seedling plates 14 and the damage of the rice seeds on the first seedling plate 14. After the management of all the first seedling plates is completed, the staff starts the first driving motor 4, the first driving motor 4 drives the first driving rod 2 to rotate, and the uppermost first seedling plate 14 moves upward, thereby driving all the first seedling plates 14 below to move upward.

[0028] Further, in the present application, the elastic member comprises a reset spring 9, one end of the reset spring 9 is connected to one of the first seedling plates 14, and the other end of the reset spring 9 is connected to another first seedling plate 14.

[0029] In the embodiment, after the plurality of first seedling plates 14 move downward into the first smooth section 7, the plurality of first seedling plates 14 are compressed under the action of gravity, so as to shorten the height between the plurality of first seedling plates 14, thereby facilitating the management of the plurality of first seedling plates 14 by the staff. Moreover, the installation of the reset spring 9 between the adjacent two first seedling plates 14 can prevent the collision and avoid the damage of the rice seeds.

[0030] Further, in the present application, the lower side of the second driving rod 5 is provided with a second smooth section 8 matched with the second seedling plate 15, the edge of the second seedling plate 15 is provided with a plurality of communication grooves 17 in the circumferential direction, the plurality of second seedling plates 15 arranged from top to bottom are provided with baffles 18 matched with the communication grooves 17 in the circumferential direction, and the inner side of the plurality of first seedling plates 14 arranged from top to bottom is provided with limiting members 16 matched with the baffles 18 in the circumferential direction.

[0031] In the embodiment, when the staff manages the plurality of seedling assemblies 10, first, the plurality of first seedling plates 14 are moved to the lower side of the bearing column 1, and then the plurality of second seedling plates 15 are controlled to move downward. When the lowermost second seedling plate 15 moves to the second smooth section 8, the lowermost second seedling plate 15 falls freely downward, and the lowermost second seedling plate 15 passes through the plurality of first seedling plates 14 one by one and finally cooperates with the lowermost first seedling plate 14. The edge of the second seedling plate 15 is provided with a plurality of communication grooves 17 in the circumferential direction. One of the communication grooves 17 of the lowermost second seedling plate 15 is provided with a baffle 18 (if the edge of the second seedling plate 15 is provided with five communication grooves 17, the five communication grooves 17 are numbered 1 to 5 respectively, the lowermost second seedling plate 15 is provided with the baffle 18 at the communication groove 17 numbered 1, the second last second seedling plate 15 is provided with the baffle 18 at the communication groove 17 numbered 2, the third last second seedling plate 15 is provided with the baffle 18 at the communication groove 17 numbered 3, and so on). If the inner side of the first seedling plate 14 is provided with five mounting points, the uppermost first seedling plate 14 is mounted with the limiting piece 16 at the first mounting point, the second seedling plate is mounted with the limiting piece 16 at the second mounting point, and so on. In this way, the five second seedling plates 15 can all fall into the corresponding first seedling plates 14. Not only is it convenient for the staff to manage the rice seeds on the second seedling plate 15, but also the first seedling plate 14 can drive the second seedling plate 15 to move upward, which is very convenient.

[0034] Further, in the present application, the plurality of spray heads 13 on the support 12 are equidistantly arranged.

[0035] In the embodiment, the equidistant arrangement of the plurality of spray heads 13 can make the sprayed water mist more uniform, so that the water mist can reach every position on the seedling assembly 10.

[0036] Further, in the present application, the edge of the first seedling plate 14 is provided with an inwardly curved arc-shaped plate 11.

[0037] In this embodiment, after the first seedling plate 14 is installed on the arc-shaped plate 11, the arc-shaped plate 11 can also be used to plant rice seeds, and the arc-shaped plate 11 is inclined inward, which can prevent the rice seeds from falling from the first seedling plate 14; further, after the first seedling plate 14 is installed on the arc-shaped plate 11, the edge is inclined inward, which can make the light be inclined to the first seedling plate 14 of the next layer.
