Description

Technical Field

[0001] This utility model relates to the field of rice seedling transfer technology, and in particular to a rice seedling transfer device for rice planting. Background Technology

[0002] Rice cultivation has a long history in my country. The rice industry is mainly distributed in the Asian monsoon region, where rice cultivation has a history of more than 7,000 years. Rice is a staple crop favored by the local people, and the rice produced accounts for the vast majority of the world's total rice production. In the process of rice cultivation, when transporting seedlings from other places to the farmland, transfer devices are needed to transport the seedlings.

[0003] By comparing a rice seedling transfer device with patent publication number CN221660759U, it is found that in this design, water is drawn out through an inlet pipe connected to one end of the pump body, and then the water source is injected into the top surface of the tray containing the seedlings through an outlet pipe to prevent the seedlings from dying due to water shortage caused by excessively hot weather. However, this device cannot adaptively control the amount of water replenished. If the amount of water is too large, the roots of the seedlings will be soaked in water for a long time, which will lead to hypoxia and other phenomena. The roots may even rot, which may lead to the death of the seedlings during the transfer process, reducing the survival rate of the seedlings during the transfer. Utility Model Content

[0004] The purpose of this invention is to provide a rice seedling transfer device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-5 As shown, a rice seedling transfer device includes a frame 100 and a transfer mechanism for transferring seedlings, the transfer mechanism being located above the frame 100.

[0028] In this embodiment, the transfer mechanism includes a transfer structure for transferring seedlings and a ventilation structure for ventilating the seedlings during transfer.

[0029] The transfer structure includes a transport box 201 mounted above the frame 100. Multiple vertically distributed slide rails 202 are provided on the inner walls of both sides of the transport box 201. A push plate 203 is slidably installed at the rear end of each slide rail 202. A compression spring connects the push plate 203 to the slide rail 202. A placement plate 204 is slidably installed between the two slide rails 202. A limit frame 205 is fixed to the side wall of the transport box 201 near the slide rails 202. A limit block 206 is slidably installed inside the limit frame 205. 06 is made of rubber. A limiting spring is connected between the limiting block 206 and the limiting frame 205. A pull rod 207 is fixed to the end of the limiting block 206 away from the placement plate 204. The pull rod 207 is made of silicone. The front end of the limiting block 206 is arc-shaped. The limiting block 206 and the placement plate 204 are slidably engaged. A material holding frame 209 is fixed to the top of the placement plate 204. A cover door is slidably installed on the front side of the transport box 201. The placement plate 204 has a water replenishment structure inside for replenishing water to the roots of the seedlings during seedling transportation.

[0030] The water replenishment structure includes a water-holding cavity 208 located at the bottom of the placement plate 204, multiple ventilation holes at the bottom of the material-holding frame 209, water control frames 213 symmetrically arranged on both sides of the material-holding frame 209 along the front-back direction, a water delivery frame 219 located at the upper end of the slide rail 202, a water pipe connected between the water delivery frame 219 and the water control frame 213, a water outlet pipe connected between the water control frame 213 and the material-holding frame 209, two water storage tanks 216 symmetrically arranged along the front-back direction located at the upper end of the transport box 201, a water pump 217 located on the side wall of the transport box 201 near the water storage tanks 216, a water inlet pipe connected between the water pump 217 and the water storage tanks 216, a water delivery pipe 218 connected between the water pump 217 and the water delivery frame 219, and a control structure for controlling the water delivery volume of the water control frame 213 located inside the water control frame 213.

[0031] The control structure includes detection chambers 210 symmetrically arranged on both sides of the water-containing cavity 208 in the front-back direction. Limiting strips 215 are fixed on the inner wall of the detection chambers 210. A float plate 211 is provided at the upper end of the limiting strips 215. The float plate 211 is slidably engaged with the detection chambers 210. Multiple overflow holes 214 are opened between the detection chambers 210 and the bottom of the water-containing cavity 208. A baffle 212 is fixed at the upper end of the float plate 211. The baffle 212 is slidably connected with the water control frame 213.

[0032] The ventilation structure includes a fixed frame 220 installed at the top of the transport box 201. Multiple ventilation fans 221 are installed at the top inside the fixed frame 220. A filter screen 222 is provided below the ventilation fans 221. The filter screen 222 is slidably connected to the fixed frame 220. A handle is fixed to the front end of the filter screen 222. The water replenishment structure can automatically replenish water to the roots of the seedlings during transportation. The amount of water replenished is greater when the weather is hotter and less when the weather is colder. The precise control of the amount of water replenishment by the water replenishment structure can prevent excessive water replenishment from causing oxygen deficiency and other effects on the roots of the seedlings, thereby improving the survival rate of the seedlings during transportation.

[0033] Working principle: First, open the cover door and insert multiple placement plates 204 into the slide rail 202. Use the limiting block 206 to limit the position of the placement plates 204. Then, place the seedlings into multiple feeding frames 209. If it is necessary to remove the placement plates 204, simply pull the pull rods 207 on both sides to move the limiting blocks 206 on both sides, so as to remove the obstruction of the placement plates 204. The placement plates 204 move forward under the pushing force of the push plate 203, and the placement plates 204 can be removed.

[0034] During the transfer of seedlings, water is pumped from the water storage tank 216 into the water delivery frame 219 by the water pump 217, then into the water control frame 213, and finally into the material holding frame 209. The water then flows into the water holding chamber 208 through the vent at the bottom of the material holding frame 209. The water then flows into the detection chamber 210 through the overflow hole 214. As the water volume gradually increases, it will push the float 211 to move upward. The float 211 will drive the baffle 212 to move upward. The baffle 212 will gradually be inserted into the water control frame 213, and the baffle 212 will control the water flow rate inside the water control frame 213.

[0035] When the water volume inside the water-holding cavity 208 is too large, the baffle 212 will block the inside of the water control frame 213, and the water flow will no longer flow into the water-holding cavity 208. As the water inside the water-holding cavity 208 is gradually absorbed by the seedlings, the water volume inside decreases, which will cause the float 211 to drive the baffle 212 to gradually move downward. At this time, the baffle 212 will no longer block the inside of the water control frame 213, and the water flow inside the water control frame 213 will flow back into the water-holding cavity 208 to continuously replenish the roots of the seedlings. Through the adaptive control of the water volume inside the water control frame 213 by the float 211 and the baffle 212, the root hypoxia of the seedlings when the water volume is too large is effectively avoided. At the same time, multiple ventilation fans 221 are activated to continuously ventilate the air inside the transport box 201, ensuring sufficient oxygen inside the transport box 201 and ensuring that fresh air is always present inside the transport box 201, thereby improving the survival rate of the seedlings during transportation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
