Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a cultivation rack for oat seedlings. Background Art

[0002] The seedling rate of oats depends on factors such as soil, water, temperature, and light. In addition to selecting seeds with full grains, it is also necessary to control the growth environment of oats to improve the seedling rate. Usually, when sowing in open soil, the environmental conditions are relatively poor, and the seedling rate of oats is low. In order to solve this problem, people choose to carry out the oat seedling raising process in an experimental greenhouse, so that it can germinate and grow seedlings under good conditions, and then transplant it to outdoor soil, so that it can have a higher seedling rate.

[0003] At present, most experimental greenhouses adopt a cultivation method of multi-layer cultivation racks. Although it can fully and effectively utilize space resources, the cultivation racks on the bottom layers have poor lighting. After the oat seeds germinate, the leaves cannot fully carry out photosynthesis, resulting in a low growth rate of the oat seeds, thereby extending the seedling cycle and affecting the subsequent transplanting work. In view of this, the present invention is specially proposed. Summary of the invention

[0007] In order to facilitate hiding the first sprocket, the transmission shaft and the second sprocket, further, a hidden cavity is installed in the base, and the first sprocket, the transmission shaft and the second sprocket are all arranged in the hidden cavity.

[0008] In order to facilitate easy placement and removal of the seedling box, the seedling box is further slidably connected to the upper end of the counterweight seat, and when the mounting rod is rotated to be parallel to the base, the seedling box is located above the mounting rod.

[0009] In order to facilitate watering of oat seeds or seedlings, a water storage cavity is further provided in the counterweight seat, and a plurality of absorbent cotton strips are equidistantly inserted into the seedling box, and the absorbent cotton strips extend downward into the water storage cavity of the counterweight seat.

[0010] In order to facilitate the rapid supply of water to multiple water storage chambers, further, the rotating bearing is hollow and connected to the water storage chamber of the counterweight seat, every two adjacent rows of the rotating bearings are connected to each other through connecting water pipes, and every two adjacent connecting water pipes are symmetrically staggered. A conveying water pipe is installed on the rotating bearing located at the top and not installed with the connecting water pipe through a rotating joint, a water storage chamber is opened in the base, and a water pump connected to the water storage chamber is installed on the base, and the water outlet of the water pump is connected to the water inlet of the conveying water pipe, and a return water pipe is installed on the rotating bearing located at the bottom and not installed with the connecting water pipe through a rotating joint, and the water outlet of the return water pipe is connected to the return water port of the water storage chamber.

[0011] In order to facilitate observation of whether the multiple water storage chambers are full of water, further, the return water pipe is a transparent water pipe.

[0012] In order to facilitate automatic shutoff of the water pump, a Z-shaped plate is slidably connected to the base near the return pipe, the lower end of the Z-shaped plate is located in the water storage chamber and directly below the water outlet of the return pipe, and a touch switch is installed on the base at the position of the Z-shaped plate, and the touch switch is electrically connected to the water pump.

[0013] In order to facilitate supporting the screw rod, further, the end of the support rod is fixedly connected with a support ring, and the support ring is sleeved on the screw rod.

[0014] In order to facilitate the flexible movement of the cultivation rack, it further includes a handle, the two ends of the handle are respectively fixedly connected to the ends of the two support rings away from the support rods, and self-locking universal wheels are installed at the four corners of the bottom of the base.

[0015] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: the present invention drives the screw rod to rotate through the driving mechanism, so that the lifting plate can be freely lifted and lowered, so that the height position of the seedling box can be flexibly adjusted. When the sunlight angle is low in the morning or evening, the seedling box can be raised so that each layer of seedlings can fully receive light; when the sunlight is strong at noon, the height of the seedling box can be appropriately lowered to avoid damage to the seedlings caused by direct sunlight, while ensuring the uniformity of light for each layer of seedlings, effectively solving the problem of insufficient photosynthesis caused by light blocking, and is conducive to cultivating strong and high-quality oat seedlings; when it is necessary to take and place a certain seedling box, the lifting plate can be lowered to a suitable height by driving the motor, so that the operator can easily and conveniently take and place the seedling box, thereby improving work efficiency and reducing the risk of damage to the seedlings, providing great convenience for daily management and maintenance work during the oat seedling raising process, and improving the convenience and efficiency of the entire seedling raising work.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example 1: Reference Figure 1-Figure 7 A cultivation rack for oat seedlings, comprising a base 1, and also comprising: a screw rod 2, symmetrically rotatably connected to one side of the base 1; a driving mechanism for driving the screw rod 2 to rotate, installed on the base 1; a lifting plate 3, threadedly connected between the two screw rods 2; a mounting rod 301, symmetrically rotatably connected to the lifting plate 3; a plurality of counterweight seats 302, all rotatably connected between the two mounting rods 301 through a rotating bearing 304, and the plurality of counterweight seats 302 are equidistantly arranged between the two mounting rods 301; a seedling box 303, placed on the counterweight seat 302; a support rod 4, symmetrically fixedly connected to both sides of the base 1, and located directly below the mounting rod 301, and the support rod 4 slides against the mounting rod 301.

[0021] The driving mechanism includes a driving motor 201, a first sprocket 202, a transmission shaft 203 and a second sprocket 204. The driving motor 201 is fixedly connected to the base 1 and is located between the two screw rods 2. The first sprocket 202 is fixedly connected to the output end of the driving motor 201, the transmission shaft 203 is fixedly connected to the lower end of the screw rod 2, and the second sprocket 204 is fixedly connected to the lower end of the transmission shaft 203. The first sprocket 202 and the two second sprockets 204 are connected by a chain.

[0022] When it is necessary to raise oat seeds on the seedling raising rack, the driving motor 201 is first started to control the first sprocket 202 to rotate, and the first sprocket 202 drives the two second sprockets 204 to rotate through the chain, and the second sprocket 204 drives the two screw rods 2 to rotate synchronously through the transmission shaft 203, and the screw rod 2 drives the lifting plate 3 to move downward, and the lifting plate 3 rotates the mounting rod 301 with the cooperation of the support rod 4 until the mounting rod 301 is placed flat on the support rod 4, thereby completing the counterweight seat 3. 02 is adjusted horizontally so that the multiple counterweight seats 302 are all on the same horizontal plane, and then the staff can place the seedling box 303 planted with oat seeds on the top of the counterweight seat 302. Since the center of the counterweight seat 302 is located at the center bottom, when the mounting rod 301 is tilted, the seedling box 303 can also be kept in a horizontal state. After the seedling box 303 is installed, the lifting plate 3 can be controlled to move up by the driving motor 201, and then the mounting rod 301 will be tilted, so that the multiple seedling boxes 303 can be placed like Figure 1The state distribution shown in FIG. 1 can not only reduce the space occupied by the cultivation rack, but also ensure that the upper seedling box 303 does not affect the photosynthesis of the oat seedlings in the lower seedling box 303 , thereby effectively ensuring the growth of the oat seedlings.

[0023] When the oat seedlings grow to a certain height and need to be taken down from the cultivation rack and transplanted outdoors, the drive motor 201 can be started again to make the mounting rod 301 horizontal again, so that the seedling box 303 at a higher position above can be lowered, and then the staff can easily remove the seedling box 303 located above and transplant the oat seedlings in the box outdoors, which provides convenience for the staff.

[0024] When the current seedling cultivation rack is used to cultivate seedlings, due to the large number of seedlings, the seedlings on the upper layer are easy to block the light of the seedlings on the lower layer, affecting the photosynthesis efficiency and further affecting the growth and development of the seedlings. However, the present cultivation rack drives the screw rod 2 to rotate through the driving mechanism, so that the lifting plate 3 can be freely raised and lowered, so that the height position of the seedling box 303 can be flexibly adjusted. When the sunlight angle is low in the morning or evening, the seedling box 303 can be raised so that the seedlings on each layer can fully receive the light; when the sunlight is strong at noon, the height of the seedling box 303 can be appropriately lowered to avoid damage to the seedlings caused by direct strong light, while ensuring the uniformity of light for the seedlings on each layer, effectively solving the problem of insufficient photosynthesis caused by light blocking, and is conducive to cultivating strong and high-quality oat seedlings.

[0025] The seedling boxes on the traditional seedling rack are difficult to take and place, and the operation is inconvenient, which increases the labor intensity and time cost, and the seedlings may be damaged due to improper operation during the taking and placing process. The present breeding rack has a unique structural design. When a seedling box 303 needs to be taken and placed, the lifting plate 3 can be lowered to a suitable height by driving the motor 201, so that the operator can easily and conveniently take and place the seedling box 303, thereby improving work efficiency and reducing the risk of damage to the seedlings. It provides great convenience for daily management and maintenance work during the oat seedling raising process, and improves the convenience and efficiency of the entire seedling raising work.

[0026] Example 2: Reference Figure 1-Figure 7 A cultivation rack for oat seedlings is basically the same as Example 1. Furthermore, a hidden cavity 101 is installed in the base 1, and the first sprocket 202, the transmission shaft 203 and the second sprocket 204 are all arranged in the hidden cavity 101. By arranging the first sprocket 202, the second sprocket 204 and the transmission shaft 203 in the hidden cavity 101, they can be protected and the overall aesthetics of the cultivation rack can be improved.

[0027] The seedling box 303 is slidably connected to the upper end of the counterweight seat 302. When the mounting rod 301 rotates to be parallel to the base 1, the seedling box 303 is located above the mounting rod 301. When the oats are cultivated for a certain period and need to be transplanted outdoors for large-scale planting, the staff can start the drive motor 201 at this time, so that the drive motor 201 drives the lifting plate 3 to move downward until the mounting rod 301 rotates to a horizontal state. Then the staff can stand on one side of the cultivation rack and pull the seedling box 303 directly to one side, so that the seedling box 303 can be removed from the counterweight seat 302. When the seedling box 303 is long, this method can be used to provide convenience for the staff to take and put the seedling box 303.

[0028] Example 3: Reference Figure 1-Figure 7 , a cultivation rack for oat seedlings, which is basically the same as Example 2, and further, a water storage cavity is opened in the counterweight seat 302, and a plurality of absorbent cotton strips 3011 are equidistantly inserted on the seedling box 303, and the absorbent cotton strips 3011 extend downward into the water storage cavity of the counterweight seat 302. By opening a water storage cavity in the counterweight seat 302 and arranging the absorbent cotton strips 3011, when the oat seeds are cultivated in the cultivation box 303, the absorbent cotton strips 3011 can transfer the water or nutrient solution stored in the water storage cavity to the soil in the seedling box 303, thereby automatically replenishing water for the oat seeds or seedlings, and there is no need for the staff to frequently replenish water in the seedling box 303. The staff only needs to regularly transfer water to the water storage cavity.

[0029] The rotating bearing 304 is hollow and connected to the water storage chamber of the counterweight seat 302. Every two adjacent rows of rotating bearings 304 are connected to each other through a connecting water pipe 307. Figure 3 As shown, every two adjacent connecting water pipes 307 are symmetrically staggered, a water delivery pipe 306 is installed on the rotating bearing 304 located at the top and not installed with the connecting water pipe 307 through a rotating joint, a water storage chamber 102 is opened in the base 1, a water pump 305 connected to the water storage chamber 102 is installed on the base 1, the water outlet of the water pump 305 is connected to the water inlet of the conveying water pipe 306, and a water return pipe 308 is installed on the rotating bearing 304 located at the bottom and not installed with the connecting water pipe 307 through a rotating joint, and the water outlet of the water return pipe 308 is connected to the water storage chamber 102. The return water port is connected to the return water port. When water needs to be added to the water storage chamber, the water pump 305 can be started at this time. The water pump 305 will transport the water or nutrient solution in the water storage chamber 102 into the water storage chamber at the top through the delivery water pipe 306. When the water storage chamber at the top is full of water or nutrient solution, the excess water or nutrient solution will flow into the water storage chamber of the next level through the connecting water pipe 307. This can be repeated to make the water storage chambers in multiple counterweight seats 302 full of water or nutrient solution. There is no need for staff to add water to multiple water storage chambers one by one, which effectively reduces the workload of staff.

[0030] Example 4: Reference Figure 1-Figure 7 , a cultivation rack for oat seedlings, which is basically the same as that of Example 3, and further, the return pipe 308 is a transparent water pipe, By making the return pipe 308 of a transparent material, when excess water flows into the water storage chamber 102 through the return pipe 308, the staff can observe whether there is water in the return pipe 308 to know whether the multiple water storage chambers are full of water, so that the staff can turn off the water pump 305, providing convenience for the staff to replenish water into the water storage chamber.

[0031] Example 5: Reference Figure 1-Figure 7 , a cultivation rack for oat seedlings, is basically the same as Example 3, and further, a Z-shaped plate 309 is slidably connected to the position of the base 1 near the return pipe 308, and the lower end of the Z-shaped plate 309 is located in the water storage chamber 102 and is located directly below the water outlet of the return pipe 308. A touch switch 3010 is installed on the base 1 at the position of the Z-shaped plate 309, and the touch switch 3010 is electrically connected to the water pump 305.

[0032] When the water storage chambers of multiple counterweight seats 302 are full of water, excess water will flow back into the water storage chamber 102 of the base 1 through the return pipe 308. When excess water flows into the water storage chamber 102 through the return pipe 308, the water flowing out of the return pipe 308 will impact the Z-shaped plate 309 downward, and then a downward pressure will be generated on the Z-shaped plate 309, so that the Z-shaped plate 309 applies pressure to the touch switch 3010, and then the touch switch 3010 will turn off the water pump 305, so that the water pump 305 stops supplying water to the water delivery pipe 306, thereby eliminating the need to manually turn off the water pump 305, effectively improving the automation of the cultivation rack.

[0033] Example 6: Reference Figure 1-Figure 7 , a cultivation rack for oat seedlings, is basically the same as Example 5, and further, a support ring 401 is fixedly connected to the end of the support rod 4, and the support ring 401 is sleeved on the screw rod 2. Through the setting of the support ring 401, the screw rod 2 can be supported to prevent the screw rod 2 from tilting or deforming under the pressure of the components connected thereto, thereby affecting the smoothness of the transmission of the lifting plate 3, and effectively improving the stability of the screw rod 2.

[0034] It also includes a handle 402, both ends of which are fixedly connected to the ends of the two support rings 401 away from the support rod 4, and self-locking universal wheels are installed at the four corners of the bottom of the base 1. When the cultivation rack needs to be moved, the limit of the self-locking universal wheel can be contacted at this time, and then the staff can push the cultivation rack through the handle 402 to push it to the designated position. There is no need to carry the cultivation rack anymore, which effectively reduces the workload of the staff.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with a preferred embodiment, it is not used to limit the present invention.
