Description

Technical Field

[0001] The utility model belongs to the technical field of seedling production equipment, and in particular relates to a tobacco seedling tray soil covering device. Background Art

[0002] When using the tobacco seedling tray, first put the seedling soil evenly into the seedling tray, then sprinkle two or three tobacco seeds in the tray, and then cover the tobacco seeds with a layer of loose soil. At the same time, to facilitate subsequent watering, the soil cannot be higher than the seedling tray.

[0003] In the prior art, for covering the soil on the seedling tray after sowing, a scraper is usually used to hang away the excess soil or a flat surface is used to press the soil, so that the soil on the seedling tray can be leveled. The purpose is to facilitate subsequent irrigation and transportation. According to the planting needs of different seeds in the seedling tray, the soil covering requirements on the seedling tray should also be adjusted. For example, the soil covering depth for corn seedlings is preferably 4-5 cm, while the soil covering thickness for rice seedlings is preferably 0.7-1 cm.

[0004] In the above planting technology, when a scraper is used to level the soil on the seedling tray, there is a chance that some of the cultivated seeds in the seedling tray will be scraped away by the scraper, resulting in a lower seedling yield rate of the seedling tray, or using a flat surface to press the soil will damage some thin seedling trays, resulting in a lower recycling rate of the seedling tray. The thickness of the soil is usually controlled manually, resulting in the inability to accurately adjust the thickness of the soil. Utility Model Content

[0025] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, a soil frame 301 for holding soil is fixedly installed on the support frame 106, and a pressing plate 302 for pressing a thickening plate 304 is slidably installed on the soil frame 301. The end of the soil frame 301 close to the conveyor belt 104 is the bottom end, and the thickness of the bottom end of the soil frame 301 is one millimeter. A plurality of funnel holes are arranged on the bottom plane of the soil frame 301, and a sealing plate 303 is slidably installed on the soil frame 301, and a plurality of closed holes are arranged on the sealing plate 303. A thickening plate 304 is also fixedly installed on the soil frame 301, and the thickening plate 304 is arranged between the sealing plate 303 and the bottom of the soil frame 301, and the thickness of the thickening plate 304 is one millimeter. A plurality of soil openings are arranged on the thickening plate 304, and the soil openings, closed holes, and funnel holes of the thickening plate 304, the sealing plate 303, and the soil frame 301 are in an overlapping state in the initial state after installation, as shown in FIG. Figure 5 In the state shown in the figure, the soil opening holes, closed holes and funnel holes are for allowing soil to enter the seedling blocks on the seedling tray 305 to cover the seeds, and adjusting the number of thickening plates 304 between the closing plate 303 and the bottom of the soil frame 301 is to adjust the thickness of the soil covering the seedling blocks, and the sliding of the closing plate 303 in the soil frame 301 will cause the closed holes to be misaligned with the soil opening holes and funnel holes, thereby preventing the soil in the soil frame 301 from continuing to pass through the closed holes.

[0026] like Figures 2 to 4 As shown, a side slide 204 is slidably mounted on the support frame 106, a side frame 207 is slidably mounted on the side slide 204, the side frame 207 is fixedly connected to the outer wall of the soil frame 301, a fixed worm 208 is rotatably mounted on the side frame 207, a sliding worm 210 is slidably mounted on the fixed worm 208, the side slide 204 is rotatably mounted on the end of the sliding worm 210 away from the side frame 207, a pressure screw 209 is rotatably mounted on the side frame 207, a pressure worm gear 212 is fixedly mounted on the pressure screw 209, the pressure worm gear 212 is meshed with the fixed worm 208, both sides of the pressing plate 302 are connected to the pressure screw 209 by threads, and the pressure screw 209 can drive the pressing plate 302 to slide on the soil frame 301 by rotating, and a clamping plate 204 is also slidably mounted on the side slide 204. 05, the clamping plate 205 is tightly connected with the sealing plate 303 at one end outside the soil frame 301, and the clamping plate 205 clamps the pressing plate 302 when it contacts with the pressing plate 302. An adjusting screw 206 is rotatably installed on the clamping plate 205, and the adjusting screw 206 is connected to the side slide frame 204 by a thread. An adjusting worm gear 211 is also fixedly installed on the adjusting screw 206, and the adjusting worm gear 211 is engaged with the sliding worm 210. When the fixed worm 208 is rotated, the fixed worm 208 can drive the sliding worm 210 to rotate, so that the fixed worm 208 and the sliding worm 210 can drive the clamping plate 205 and the pressing plate 302 to move away from the conveyor belt 104. After the movement, the number of thickening plates 304 can be adjusted, and the thickness of the covering soil can be increased by increasing the thickening plates 304.

[0027] like Figures 2 to 4 As shown, a switch motor 201 is fixedly installed on the outer side of the support frame 106, a movable swing arm 202 is slidably installed on the output shaft of the switch motor 201, a buffer spring is fixedly installed on the movable swing arm 202, and the other end of the buffer spring is fixedly installed on the output shaft of the switch motor 201, and a sliding block 203 is rotatably installed on the other end of the movable swing arm 202, and the sliding block 203 is slidably connected to the side sliding frame 204.

[0028] The working principle of this embodiment is as follows: when the device is working, the seedling tray 305 filled with soil is placed on the conveyor belt 104, and the conveyor belt 104 is allowed to pass through the seeding machine 101, and the seeding machine 101 will put seeds into each seedling groove on the seedling tray 305, and two to three seeds are placed in each seedling groove. Then the conveyor belt 104 drives the seedling tray 305 to move to the bottom of the soil frame 301, and the seedling grooves on the seedling tray 305 are aligned with the funnel holes on the soil frame 301, and then the translation cylinder 107 is started, and the translation cylinder 107 drives the support frame 106 and the soil frame 301 to move towards the conveyor belt 104, so that the bottom end of the soil frame 301 contacts the seedling tray 305.

[0029] After the bottom end of the soil frame 301 contacts the plane of the seedling tray 305, the switch motor 201 can be started to allow the side slide frame 204 to slide on the support frame 106, so that the clamping plate 205 drives the sealing plate 303 to move, and the closed holes on the sealing plate 303 are aligned with the soil opening holes and the funnel holes, so that the soil can enter each seedling raising concave block on the seedling raising tray 305, and then the sealing plate 303 moves again to make the closed holes misaligned with the soil opening holes and the funnel holes, so that the soil in the soil frame 301 cannot flow out, and then the translation cylinder 107 drives the bottom end of the soil frame 301 to align with the seedling raising tray 305. The flat plate on the seedling tray 305 is separated, and the conveyor belt 104 can continue to drive the seedling tray 305 to move. When passing through the pressing cylinder 105, the pressing cylinder 105 can be driven by an external driving device, or the pressing cylinder 105 can be connected to the driving source of the conveyor belt 104 to allow the pressing cylinder 105 to rotate. The purpose is to allow the pressing cylinder 105 to simply press the soil covered on each seedling groove on the seedling tray 305 to prevent the soil from flowing out of the seedling groove during subsequent watering. After that, the conveyor belt 104 will continue to drive the seedling tray 305 to move to the outlet plate 103.
