Description

Technical Field

[0001] The present invention relates to the technical field of seed breeding, and specifically to a batch breeding machine. Background Art

[0002] With the acceleration of the global ecological restoration process, the surging demand for urban greening, and the upgrading of the forestry industrialization, the social demand for mass tree breeding has shown an explosive growth. The traditional seedling raising mode relies on manual operation, and there are bottlenecks such as long cycle, low efficiency, and insufficient standardization. Open-air nurseries are vulnerable to climate interference, with large fluctuations in survival rate. It is difficult to match the requirements of large-scale afforestation projects for the quantity and specification uniformity of seedlings in single-plant cultivation. And the device for mass tree breeding by soilless cultivation is a device designed specifically for efficiently and large-scale cultivating tree seedlings, which can effectively improve the breeding efficiency, scale, and survival rate. In the prior art, multi-layer soilless cultivation is used to improve the space utilization rate for large-scale tree seedling breeding work. However, it is difficult to ensure that each layer of seedlings can receive sufficient sunlight, and long-term use of light irradiation will have an adverse impact on the growth of seedlings.

[0003] The patent with the publication number of CN212993300U discloses a seedling cultivation device. This patent includes a square cylinder and a bottom plate, and the cylinder and the bottom plate are made of hard materials respectively. During use, when it is necessary to move or carry the seedlings, the square cylinder can be directly lifted and moved, and the operation of carrying and moving the seedlings is simple and convenient, and it is easy to use. Since the wall of the square cylinder is provided with longitudinal strip-shaped holes, when the seedlings are cultivated in the square cylinder and the root system of the seedlings grows to the longitudinal strip-shaped holes on the wall of the square cylinder, the root system of the seedlings will extend out of the longitudinal strip-shaped holes, and the tip of the root will dry up and stop growing. The root system of the seedlings will not form root knots or clusters, and the survival rate after transplantation is high. Since the bottom plate is placed inside the cylinder and is detachably connected to the cylinder wall, when transplanting the seedlings, the bottom plate is removed, and then the seedlings together with the nutrient soil can be extruded upward or downward along the square cylinder. At the same time, the bottom plate and the cylinder can be recycled and reused, with low use cost, no pollution, and easy to use. Although this patent solves the above problems, there is still a problem that it is difficult to ensure that the seedlings can receive sufficient sunlight when cultivating multiple layers of seedlings, resulting in a decrease in cultivation efficiency. Therefore, a batch breeding machine is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a batch breeding machine for the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A batch breeding machine includes a seedling raising box. The inner surface of the seedling raising box is fixedly connected with a front baffle. The inner surface of the seedling raising box is fixedly connected with a first support rod. A rotating seat one is hinged to the circumferential surface of the first support rod. One end of the rotating seat one away from the first support rod is fixedly connected with a seedling inserting plate. A rotating seat two is hinged to the circumferential surface of the first support rod. One end of the rotating seat two away from the first support rod is fixedly connected with a liquid storage tank. A quick fixing device for quickly fixing the seedling inserting plate and the liquid storage tank to protect the seedlings is arranged inside the seedling raising box. A heat preservation liquid infusion device for conveying nutrient solution during the heat preservation process of the liquid storage tank is arranged inside the seedling raising box. The inner surface of the seedling raising box is fixedly connected with a second support rod. An arc-shaped side cover is hinged to the circumferential surface of the second support rod. A fixed plant growth lamp is fixedly connected to the top end of the inner surface of the seedling raising box. A movable plant growth lamp is fixedly connected to the lower surface of the liquid storage tank. The rear side surfaces of the seedling inserting plate and the front baffle are in contact with each other. The rear side surfaces of the liquid storage tank and the front baffle are in contact with each other. The arc-shaped side cover and the inner surface of the seedling raising box are in contact with each other. Open the arc-shaped side cover, pour the nutrient solution into the liquid storage tank, then insert the seedlings into the seedling inserting plate, and then close the arc-shaped side cover to cultivate the seedlings. At the same time, sunlight can shine on the seedlings through the arc-shaped side cover. At night, start the fixed plant growth lamp and the movable plant growth lamp to irradiate the seedlings. When the external sunlight is sufficient, open the arc-shaped side cover and rotate the rotating seat one and the rotating seat two. The rotating seat one and the rotating seat two drive the seedling inserting plate and the liquid storage tank to rotate respectively, so that the seedling inserting plates and the liquid storage tanks on each layer are staggered. When it is necessary to add nutrient solution or remove impurities inside the liquid storage tank, rotate the seedling inserting plate to stagger the seedling inserting plate and the liquid storage tank. At this time, the nutrient solution can be quickly poured into the liquid storage tank.

[0006] The top end of the lifting plug in the lifting plug has a spring, and the bottom end of the lifting plug has a spring, and the bottom end of the lifting plug has a spring, and the bottom end of the lifting plug has a spring. When the second through hole provided on the positioning shaft is aligned with the movable clamping rod, the elastic reset effect of the spring one pulls the contact ring upward, and the contact ring drives the movable clamping rod to slide upward and insert into the second through hole to lock with the positioning shaft, thereby locking the arc side cover with the front baffle and the seedling box.

[0007] Preferably, the heat-insulated infusion device includes a plug rod, the top end of the plug rod is fixedly connected with a pull plate, the inner surface of the liquid storage pool is fixedly connected with a sleeve shaft, the heat-insulated infusion device further includes an inner sleeve, the front side surface of the front baffle is fixedly connected with an outer sleeve, the inner surface of the outer sleeve is slidably connected with a movable sealing cylinder, one side of the pull rod close to the front baffle is fixedly connected with a pressing plate, the circumferential surface of the plug rod is slidably connected with the inner surface of the seedling-inserting plate, a second spring is arranged between the lower surface of the pull plate and the upper surface of the seedling-inserting plate, a through hole three is opened inside the sleeve shaft, and the through hole three is in contact with the circumferential surface of the plug rod, the inner sleeve is fixedly connected with the inner surface of the liquid storage pool, an electromagnetic valve is arranged inside the inner sleeve. Pull the pull plate upward, the pull plate drives the plug rod to slide upward and withdraw from the sleeve shaft. At this time, the liquid storage pool and the seedling-inserting plate can be separated. When the plug rod is aligned with the sleeve shaft, release the pull plate, and the elastic reset effect of the second spring drives the pull plate to move downward. The pull plate then drives the plug rod to slide downward and insert into the through hole three opened inside the sleeve shaft, so as to lock the liquid storage pool and the seedling-inserting plate, making the liquid storage pool and the seedling-inserting plate keep consistent during the movement. When closing the arc-shaped side cover, the arc-shaped side cover drives the seedling-inserting plate and the liquid storage pool to reset, making the inner sleeve align with the outer sleeve. At the same time, the pull rod drives the pressing plate to approach the movable sealing cylinder. When the arc-shaped side cover is completely attached to the front baffle, the pressing plate squeezes the movable sealing cylinder to move backward and insert into the inner sleeve, so as to seal the inner sleeve and the outer sleeve. At this time, the nutrient solution can be input into or extracted from the liquid storage pool through the movable sealing cylinder.

[0008] Adopting the above technical solution, the present invention can bring the following beneficial effects: 1. For this batch breeding machine, when starting at night, the fixed plant growth lamp and the movable plant growth lamp are turned on to irradiate the seedlings, improving the breeding efficiency. Each layer of seedling-inserting plate and liquid storage pool are staggered, preventing the seedling-inserting plates from overlapping and affecting the sunlight irradiation area of the bottom seedlings, making the seedlings receive more sufficient light. The staggered arrangement of the seedling-inserting plate and the liquid storage pool can quickly pour the nutrient solution into the liquid storage pool, and at the same time, it is more convenient to clean the impurities inside the liquid storage pool.

[0009] 2. For this batch breeding machine, the seedling-inserting plate moves together with the opening and closing of the arc-shaped side cover, so that it can be automatically staggered while the arc-shaped side cover is opened, improving the use convenience of the device.

[0010] 3. For this batch breeding machine, the movable clamping rod slides upward and inserts into the through hole two to lock with the positioning shaft, so that the arc-shaped side cover is locked with the front baffle and the seedling-raising box, quickly closing the device to protect the seedlings, and at the same time further improving the use convenience of the device.

[0011] 4. For this batch breeding machine, the liquid storage pool and the seedling-inserting plate are locked, making the liquid storage pool and the seedling-inserting plate keep consistent during the movement, preventing the liquid storage pool from shifting and causing the seedling roots to be unable to insert into the liquid storage pool, so that the seedling roots can be continuously immersed in the nutrient solution, improving the seedling-raising effect.

[0012] 5. For this batch breeding machine, the movable sealing cylinder moves backward and inserts into the inner sleeve, so that the inner sleeve and the outer sleeve are sealed. At this time, the nutrient solution can be input into or extracted from the liquid storage tank through the movable sealing cylinder, enabling the seedling raising box to control the absorption amount of the nutrient solution by the seedlings during heat preservation, and further improving the seedling raising effect.

Each layer of the seedling inserting plate 5 and the liquid storage tank 7 are staggered to prevent the seedling inserting plates 5 from overlapping and affecting the sunlight irradiation area of the bottom seedlings, making the seedlings receive more sufficient light. The staggering of the seedling inserting plate 5 and the liquid storage tank 7 can quickly pour the nutrient solution into the liquid storage tank 7, and at the same time, it is more convenient to clean the impurities inside the liquid storage tank 7.
