Description

Technical Field

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

[0002] As an important economic crop, flue-cured tobacco is one of the important sources of fiscal revenue for many places. Seedling cultivation plays a very important role in the production process of flue-cured tobacco. The sowing link is the key to flue-cured tobacco seedling cultivation. The sowing quality directly determines the quality of tobacco seedlings. Moreover, tobacco seedlings grow weakly and it is difficult to cultivate strong seedlings.

[0003] At present, floating seedling technology is often used to plant tobacco seedlings. After the floating seedlings are sown and placed in the seedling tray, a layer of covering soil is usually spread to cover them in order to increase the emergence rate, so as to keep the seeds moist and increase the emergence rate. However, manual spreading usually results in uneven spreading, resulting in inconsistent water absorption of tobacco seeds, uneven emergence of tobacco seedlings, and poor uniformity, which has a certain impact on the transplanting and field management of tobacco leaves.

[0032] like Figures 1 to 6 The floating seedling raising convenient soil cover device shown comprises a base frame 1 and a soil covering mechanism 2. The base frame 1 comprises two fixing rods 11 and a crossbeam 12 connecting the two fixing rods 11, and the crossbeam 12 is fixed to both sides of the fixing rods 11. The soil covering mechanism 2 is installed between the two fixed rods 11, and the soil covering mechanism 2 includes a silo 21, a conveyor belt 22 and a moving wheel 23. The silo 21 is provided with an opening at the bottom, and the silo 21 includes a front plate 211, a rear plate 212 and two side plates 213 connecting the front plate 211 and the rear plate 212. The conveyor belt 22 is arranged at the opening at the bottom of the silo 21, and the conveyor belt 22 is clearance-matched with the rear plate 212. A discharge port 24 is formed between the conveyor belt 22 and the front plate 211. A driving roller 221 for driving the conveyor belt 22 is provided in the conveyor belt 22, and the moving wheel 23 is installed on both sides of the driving roller 221, and the moving wheel 23 is mounted above the fixed rod 11. The moving wheel 23 drives the conveyor belt 22 to rotate, thereby driving the soil in the silo 21 to flow out evenly, so as to achieve uniform soil covering of the seedling tray.

[0033] In one embodiment, first, the base frame 1 is moved to the top of the seedling tray, or the seedling tray is moved to the bottom of the base frame 1. Then, soil suitable for the growth of tobacco seeds in the seedling tray is added to the silo 21, and the soil covering mechanism 2 is pushed so that the moving wheel 23 of the soil covering mechanism 2 slides along the extension direction of the fixed rod 11. When the moving wheel 23 rotates, the driving roller 221 of the conveyor belt 22 is driven to rotate, that is, the moving wheel 23 and the conveyor belt 22 keep running synchronously. Since the conveyor belt 22 is arranged at the opening at the bottom of the silo 21, the conveyor belt 22 plays a bearing role for the soil. When the conveyor belt 22 moves, the soil above the conveyor belt 22 flows out from the discharge port 24 between the front plate 211 and the conveyor belt 22 under the drive of the conveyor belt 22, so as to cover the seedling tray with soil. The lengths of the seedling tray, the crossbeam 12 and the silo 21 are consistent, so that the seedling tray can be covered with soil at one time. The discharge port 24 is rectangular, and the discharge height of the discharge port 24 is consistent, so that the thickness of the covering soil layer is consistent, thereby improving the covering soil quality and efficiency of the seedling tray.

[0034] Preferably, a plurality of positioning holes 2111 are provided at the bottom of the front plate 211, and the positioning holes 2111 are evenly distributed along the extension direction of the driving roller 221.

The number of the positioning holes 2111 is the same as that of the strip holes 251, and the positioning holes 2111 are aligned with the strip holes 251. The adjustment plate 25 is provided with the strip holes 251, so as to facilitate adjustment of the height of the adjustment plate 25 relative to the front plate 211, so as to adjust the distance between the adjustment plate 25 and the conveyor belt 22, and to adjust the thickness of the covering soil. The use of a plurality of positioning holes 2111 and a plurality of strip holes 251 increases the stability of the connection between the adjustment plate 25 and the front plate 211.

[0035] In one embodiment, an adjustment plate 25 is fixedly installed on the front side of the front plate 211. By adjusting the relative position of the adjustment plate 25 and the front plate 211, the blocking degree of the adjustment plate 25 on the discharge port 24 is adjusted, so that the discharge height of the discharge port 24 can be adjusted. That is, by adjusting the position of the adjustment plate 25 relative to the front plate 211, the thickness of the covering soil layer can be adjusted to adapt to the thickness of the covering soil layer required by the seedling tray when planting tobacco seeds.

[0036] The vertical height of the adjustment plate 25 is adjusted according to the required thickness of the covering layer, and then bolts can be passed through the strip holes 251 and the positioning holes 2111 to fix the positions of the adjustment plate 25 and the front plate 211 .

[0037] Preferably, a first arc plate 252 is provided at the bottom of the adjustment plate 25 , and the distance between the first arc plate 252 and the conveyor belt 22 gradually decreases in the direction from the rear plate 212 to the front plate 211 .

[0039] In one embodiment, a second curved plate 2121 is provided below the rear plate 212, which can reduce the amount of soil flowing out to the outside at the gap between the second curved plate 2121 and the conveyor belt 22. It should be noted that the gap between the conveyor belt 22 and the rear plate 212 is very small, and the amount of soil flowing out to the outside at the gap between the conveyor belt 22 and the rear plate 212 can be basically ignored, and has basically no effect on the soil covering quality of the soil covering mechanism 2.

[0040] Preferably, a push handle 26 is fixed to the outer side of the rear plate 212 to facilitate the pushing of the entire soil covering mechanism 2 .

[0041] Preferably, a driving roller 221 and a driven roller 222 are provided on the inner side of the conveyor belt 22. The driven roller 222 is rotatably connected between the two side plates 213. The driving roller 221 is fixedly connected to the moving wheel 23. The moving wheel 23 can drive the driving roller 221 to rotate.

The moving wheel 23 mounted above the fixed rod 11 is prevented from deflecting, and the moving wheel 23 is effectively ensured to be able to move along the extension direction of the fixed rod 11, thereby improving the uniformity of the soil layer on the surface of the seedling tray.

[0043] In one embodiment, the fixing rod 11 adopts an existing square tube profile. According to the actual situation, a square tube of a suitable length can be adopted and inserted between the two crossbeams 12 to adapt to the laying length of the seedling tray in the seedling shed. The square tube has a simple structure, low cost, and light weight for easy transportation. The wheel body 231 of the moving wheel 23 abuts against the square tube, and the distance between the two wheel plates 232 is slightly larger than the width of the square tube. The wheel plates 232 structure is fixedly arranged on both sides of the wheel body 231 to prevent the soil covering mechanism 2 from running off when moving along the square tube, thereby improving the soil covering quality.

[0044] Preferably, a rubber anti-skid ring is provided on the surface of the wheel body 231 to increase the friction between the moving wheel 23 and the fixed rod 11 and prevent the moving wheel 23 and the fixed rod 11 from slipping.

[0045] Preferably, a lifting handle 121 is also installed on the crossbeam 12 to facilitate lifting of the base frame 1.

[0046] Preferably, a support seat 13 is installed around the base frame 1, and the support seat 13 includes a fixed block 131, an adjustment rod 132 and a support plate 133.

[0047] In one embodiment, by screwing the adjusting rod 132, the position of the adjusting rod 132 relative to the fixing block 131 is adjusted, and then the distance between the supporting plate 133 and the fixing block 131 is adjusted to achieve height adjustment of the bottom frame 1. For seedling trays of different heights, the bottom frame 1 can be adjusted to a suitable height to increase the adaptability range of the bottom frame 1.

[0048] When the floating seedling raising convenient soil covering device is used, the covering soil can be evenly spread on the seedling raising tray after sowing, so that the tobacco seeds can obtain moisture evenly, which promotes the tobacco seeds to germinate evenly and grow in an orderly manner.
