Description

Technical Field

[0001] The utility model relates to the technical field of rice planting and discloses a rice seedling raising soil covering device. Background Art

[0002] In modern planting technology, rice seeds are germinated and raised indoors or in greenhouses. This can increase the germination rate of rice seeds and control the growth cycle of rice seeds. Indoor seedling raising is carried out on special rice seedling trays. When the rice seedling trays are used, the trays are first filled with predetermined soil, and then the rice seeds are sown into the trays using a seeder. The surface of the trays is then covered with a layer of soil with a thickness of 1 to 4 centimeters. The covering soil particles need to be determined according to the properties of the soil or the quality of the rice seeds.

[0003] The Chinese utility model patent with announcement number: CN207885161U discloses a rice seedling swing plate soil covering device. This device adjusts the soil thickness at the bottom of the seedling trough by adjusting the height of the soil covering scraper. The soil covering scraper rotates on the rotating shaft and the matching rotating shaft, making the soil covering scraper easy to operate. This rice seedling swing plate soil covering device is easy to adjust, so that the thickness of the soil covering the bottom of the seedling trough is easy to control, which brings convenience to the adjustment of the device.

[0004] In the above-mentioned device and the prior art, the operating steps of the attached drawings are to directly cover the rice seeds with covering soil, and then use a scraper to scrape off the excess covering soil, so as to control the thickness of the covering soil. The coarseness of the covering soil cannot be effectively controlled. At the same time, when using the scraper, there will be an unintentional downward pressure action, causing the covering soil to become more compact. Combined with the subsequent watering work, it will take a long time for the rice seeds to break through the soil. Utility Model Content

[0022] like Figures 2 to 6As shown, the transverse plate 103 is fixedly mounted with a main bracket 107, and an end of the main bracket 107 away from the transverse plate 103 is fixedly mounted with a blocking cylinder 301, an outer sieve cylinder 302 is rotatably mounted in the blocking cylinder 301, an inner sieve cylinder 303 is rotatably mounted in the outer sieve cylinder 302, an outer leakage hole is provided on the outer sieve cylinder 302, and an inner leakage hole is provided on the inner sieve cylinder 303.

In this state, the swing handle 309 can be manually pulled to move the swing handle 309 in the adjustment slot on the arc chuck 306. The purpose is to misalign the outer leakage hole on the outer sieve cylinder 302 with the inner leakage hole on the inner sieve cylinder 303 to reduce the size of particles that can fall out of the outer sieve cylinder 302.

[0023] like Figure 2 , Figure 4 , Figure 5As shown, a main motor 201 is fixedly mounted on the main bracket 107, and the main motor 201 is arranged on the outer wall of the blocking cylinder 301. A main gear 204 is fixedly mounted on the output shaft of the main motor 201, and the main gear 204 is meshed with the outer gear plate 305. A swing cam 203 is also rotatably mounted on the main bracket 107, and the swing cam 203 contacts the lower shaking plate 205 to allow the lower shaking plate 205 to reciprocate. A secondary belt 202 is also arranged on the main gear 204, and the other end of the secondary belt 202 is arranged on the swing cam 203.

[0024] Working principle of the device: Before working, a large amount of soil needs to be placed in the collecting box 101, and then the device is placed at the end of the rice seed seedling production line. When the seedling tray that has completed the pre-treatment is transported to the conveyor belt 104, the pulley 105 can be started to drive the seedling tray to move to the bottom of the lower shaking plate 205 through the conveyor belt 104. Then the main motor 201 is started, and the main motor 201 drives the outer gear plate 305 and the outer screen drum 302 to rotate through the main gear 204. At this time The outer sieve drum 302 will rotate with the inner sieve drum 303. The purpose of this is to allow the soil in the collection box 101 to fall from the side conveying pipe 108 into the feed seal plate 304, and then the soil enters the inner sieve drum 303 from the feed seal plate 304. At this time, the inner sieve drum 303 and the outer sieve drum 302 are in a rotating state, so the soil will continuously collide in the feed seal plate 304. Only soil particles that can pass through the external leakage holes on the outer sieve drum 302 and the internal leakage holes on the inner sieve drum 303 can fall from the opening at the horizontal plate 103 to the lower shaking plate 205.

[0025] When the main motor 201 is started, the swing cam 203 will also be driven to rotate, and the swing cam 203 will drive the lower shaking plate 205 to slide back and forth on the horizontal plate 103, so that the soil dropped on the lower shaking plate 205 can be further dispersed, and the soil on the lower shaking plate 205 can be evenly dropped out from the auxiliary sieve holes on the inner sieve plate 208 and the main sieve holes on the lower shaking plate 205, so that the soil falls on the surface of the seedling plate, and the auxiliary sieve holes on the inner sieve plate 208 and the main sieve holes on the lower shaking plate 205 can screen the soil particles again.

[0026] When the coarseness of soil particles needs to be adjusted, the misalignment handle 307 can be manually driven to drive the convex block 308 to disengage from the adjustment scale on the arc chuck 306, and then the swing handle 309 can be pulled to drive the inner sieve drum 303 to slide relative to the outer sieve drum 302 and the outer toothed disc 305, so as to adjust the misalignment state of the outer leakage hole on the outer sieve drum 302 and the inner leakage hole on the inner sieve drum 303. After the adjustment is completed, the misalignment handle 307 can be rotated again to allow the misalignment handle 307 to move. The convex block 308 is driven to fit with the adjustment scale on the arc chuck 306, so that the coarseness and fineness of the soil particles can be adjusted to meet the requirements of different rice seedlings. The adjustment handle 206 can also be rotated here to allow the adjustment handle 206 to drive the adjustment plate 207 and the inner sieve plate 208 to move, so that the secondary sieve holes on the inner sieve plate 208 and the main sieve holes on the lower shaking plate 205 are misaligned to reduce the soil particles that can pass through the secondary sieve holes and the main sieve holes, and at the same time reduce the thickness of the soil scattered on the seedling tray in the same period of time.
