Detailed Description

For a better understanding of the present invention, embodiments thereof are explained in detail below with reference to the accompanying drawings.

The soil covering assembly shown in the attached drawings 1 to 6 comprises a frame body 1, wherein as shown in the attached drawings 1, the frame body 1 is a square frame, a connecting end 11 capable of being connected with a transplanting machine is arranged at the front end of the frame body 1, the transplanting machine is an existing product, a connecting hole 111 is formed in the connecting end 11, the frame body 1 and the transplanting machine can be connected together through a pin, and the frame body 1 can also be fixed at the rear end of the existing transplanting machine in a welding mode. The frame body 1 is rotatably provided with a rotating shaft 12, and specifically, two bearings can be sleeved on the rotating shaft 12, and the outer rings of the bearings are fixed on the frame body 1. The two ends of the rotating shaft 12 are respectively provided with a roller 13, in order to increase friction and avoid the roller 13 from slipping, each roller 13 is provided with an anti-slip strip 131, the anti-slip strips 131 are in an angle shape, and the anti-slip strips 131 can be formed by welding metal strips.

The soil digging device 2 is arranged on the frame body 1, the soil digging device 2 comprises a central plate 21 fixed in the middle of a rotating shaft 12 and edge plates 22 symmetrically arranged on the left side and the right side of the central plate 21, the central plate 21 and the edge plates 22 are cylindrical as shown in the attached drawing 1, a plurality of sliding rods 23 are arranged between each edge plate 22 and the central plate 21 at equal intervals in the circumferential direction, four sliding rods 23 are shown in the attached drawing 1, each sliding rod 23 is square, each sliding rod 23 is provided with a sliding block 24 in a sliding manner, and the concrete implementation mode is as follows: the top end of the sliding block 24 is provided with a square hole 242 matched with the sliding rods 23, when the sliding block 24 is used, the sliding rod 23 is sleeved with the sliding block 24, in order to reduce sliding friction, a rolling ball can be arranged on the inner wall of the square hole 242, meanwhile, one side of each sliding rod 23 can be provided with one sliding rod 23, and therefore each sliding block 24 is sleeved on the two sliding rods 23. The end of the sliding block 24 is slidably provided with a soil digging plate 25, as shown in fig. 3, the specific implementation mode is as follows: an open groove 241 is arranged at the bottom end of the slide block 24, and the top end of the soil-raking plate 25 slides in the open groove 241. A jacking spring 26 is arranged between the sliding block 24 and the soil-raking plate 25, the jacking spring 26 is positioned in the open slot 241, and two ends of the jacking spring 26 respectively jack against the soil-raking plate 25 and the inner wall of the open slot 241.

Each sliding rod 23 is sleeved with a return spring 27, and two ends of each return spring 27 are respectively propped against the sliding block 24 and the central plate 21; the frame body 1 positioned at the left side and the right side of the central plate 21 is respectively and symmetrically provided with a spiral guide rod 28, as shown in the attached drawings 2 and 5, the guide rod 28 is spiral and has 0.5 circle, and in actual operation, the thread pitch and the number of circles of the guide rod 28 can be adjusted according to requirements. Under the action of the guide rod 28, the two sliding blocks 24 and the soil-raking plates 25 slide from two ends to the middle along with the rotation of the rotating shaft 12, as shown in fig. 6, in the process that the two soil-raking plates 25 slide to the middle, soil can be raked to the roots of the tobacco seedlings, and the roots of the tobacco seedlings are earthed. Therefore, the tobacco seedlings can not be pressed down by the soil covering disc 31 when the soil is turned over, and the purpose of fully covering the soil is achieved. The spiral center line of the guide rod 28 is located on the axis of the rotating shaft 12, and the end of the guide rod 28 is fixedly connected with the frame body 1 through a round rod 281.

When the slide block 24 is not slid to the middle position, the soil scraping plate 25 is already contacted with soil, then the soil scraping plate 25 carries the soil to move towards the middle, and the soil scraping depth of the soil scraping plate 25 is changed along with the elastic force of the jacking spring 26. In practical application, the elastic force of the abutting beach spring 6 does not need to be too large, and only a layer of soil needs to be lightly scraped. In order to avoid carrying too little soil, the bottom end section of the soil-scraping plate 25 is provided with an inclined cone shape, so that the soil-scraping plate 25 can easily fall into the ground. The time of taking off the soil board 25 underground is very short, later along with slider 24 slides along guide bar 28, slider 24's overall position can rise, at this moment, under the effect of top tension spring 26, the bottom of taking off soil board 25 still contacts soil, finally takes off the root of tobacco seedling with soil, the utility model discloses mainly transplant the earthing work in the work to the tobacco seedling, other types of transplantation of course also can use.

The soil digging device 2 and the transplanter are synchronous, namely the soil digging device 2 performs soil digging for each tobacco seedling, in order to ensure the synchronization, a fluted disc 211 is fixed on the central plate 21, and when in use, the fluted disc 211 is in driving connection with a power device on the transplanter through a chain.

The bottom end of the soil digging plate 25 is arranged in a disc shape, and an arc-shaped groove 251 is formed in the soil digging plate 25. Therefore, when the soil digging plate 25 rotates, the bottom end of the soil digging plate 25 still contacts and carries soil, and as with a shovel, the soil can be still grabbed no matter how the handle of the shovel swings as long as the bottom end contacts the ground.

The rear side bilateral symmetry of support body 1 can be dismantled and set up two lifter 3, every the rotatable earthing dish 31 that sets up in bottom of lifter 3. And the side wall of the frame body 1 corresponding to the lifting rod 3 is respectively in threaded connection with a fixing bolt 14, the side wall of the lifting rod 3 is provided with a row of fixing holes 32, and the inner side end of the fixing bolt 14 is pressed against one of the fixing holes 32.
