In order to reduce manpower and facilitate field operation, the pinion 12 is connected with a motor 13, the motor 13 is fixed on the frame 1, and the motor 13 rotates to drive the pinion 12 and the corresponding wheel 2 to rotate simultaneously.
To prevent the wheel 2 from slipping, a plurality of small plates 14 perpendicular to the outer circumferential surface of the wheel 2 are fixed to the outer edge of the wheel 2.
In order to facilitate the manual change of the travelling direction, a handle 15 is fixed on the left side of the frame 1.
It is worth noting that, in the invention, the lowest side of the right end of the shovel plate 3 is positioned at the middle part of the side surface of the ridge body, taking fig. 1 as an example, when the whole device moves rightwards, the shovel plate 3 firstly shovels up the mulch film, then lifts the soil sealing at the two sides of the mulch film, and continues to move rightwards, the shovel plate 3 gradually lifts up the mulch film, and as the left end of the shovel plate 3 is inclined inwards, the mulch film is finally put on the upper end of the tobacco plant, so that the whole tobacco plant is protected by the mulch film, and the tobacco leaves of the tobacco plant are prevented from being damaged by new soil; in order to enable the lower end of the scraping plate to be inserted into a soil layer and push new soil to approach the middle, a balancing weight can be placed at the upper end of the frame 1.
When the device is used, as shown in fig. 1, the device is arranged on a ridge body, the whole device is pushed to move rightwards, the shovel plate 3 is positioned between a mulching film and the surface of the ridge body, the lower end of the movable column 6 is inserted into a soil layer, the motor 13 is started, the motor 13 drives the wheel 2 to roll rightwards, the shovel plate 3 lifts up the mulching film along with the rightwards movement of the shovel plate 3, the soil sealing originally used for pressing the mulching film is lifted off, and then two sides of the mulching film are finally put on tobacco plants to protect the tobacco plants; meanwhile, the motor 13 drives the pinion 12 to rotate, the pinion 12 drives the rotating plate 5 to rotate through the gear ring 11, the rotating plate 5 drives the movable columns 6 to rotate around the cylinder 7 at the same time, when the movable columns 6 are positioned at the right half part of the cylinder 7, the convex blocks 9 on the movable columns 6 move along the cam grooves 8, and as the right half part of the cam grooves 8 is in a regular semicircular shape (shown in fig. 7), the movable columns 6 do not move up and down, the shovel blades 10 of the movable columns 6 shovel soil layers on the sides of ridges, the soil layers are gathered upwards by the movable columns 6, so that new soil gathers at the rhizome parts of tobacco seedlings, and hilling is realized.
In the above, the movable column 6 continues to rotate along with the rotating plate 5, when the movable column 6 is located at the left side of the cylinder 7, the protruding block 9 will move along the left half part of the cam groove 8, and since the left half part of the cam groove 8 is wavy, the protruding block 9 drives the movable column 6 to move up and down, and the movable column 6 compacts and forms the side surface of the ridge downward through the shovel blade 10 at the lower end.
The wheel 2 on the right side of the middle rotating plate 5 in the drawing can be seen from the use process, the wheel 2 on the left side can also be provided with the same characteristics of the rotating plate 5, the movable column 6, the cam groove 8 and the like, the hilling can be realized, the compaction forming of the side surface of the ridge can also be realized, and if the compaction forming is implemented, the use strength of the movable column 6 and the raised blocks 9 on the movable column can be effectively reduced, thereby being beneficial to prolonging the service life.
According to the invention, the shape of the shovel plate 3, especially the overlooking projection, is in a zigzag bending shape, and extends from right to left to two sides of the ridge body, so that soil sealing and cleaning at two sides of the ridge body can be facilitated, tobacco plants are prevented from being damaged by soil sealing and smashing, then the shovel plate 3 is high and low in left and right, when the mulching film reaches the left end of the shovel plate 3, the right movement is continued, and two sides of the mulching film are erected on the tobacco plants at the moment, so that tobacco plant protection is realized, and the seedling pressing probability during the soil banking of the scraping plate can be avoided to a great extent.
In the invention, in rightward movement, the mulching film is lifted by the shovel plate 3, then soil layers at the front side of the cylinder 7 are continuously gathered by the movable columns 6, the root of tobacco seedlings is hilled up, after the movable columns 6 move to the left side of the cylinder 7, the movable columns 6 and the shovel blades 10 at the lower ends of the movable columns serve as compaction tools, and the side surfaces of the ridges are compacted and formed, so that the ridge body collapse caused by later rain wash can be effectively prevented, and the root systems of the tobacco seedlings are prevented from being exposed as much as possible.
According to the novel tobacco film uncovering and ridging process, the mulching film is firstly erected on tobacco seedlings towards the middle according to the process, and then ridging is carried out, so that the seedling pressing probability is reduced. When the invention is used, the invention accords with the operation flow of a new process, and compared with the traditional ridging device, no special person is required to take off and pull tobacco leaves of tobacco seedlings, the number of operators is reduced, the manual dependence is reduced, the quality and quantity are ensured, the operation is completed, and the invention accords with the development requirement of new agriculture.
The invention has smart structure, can lift the mulching films at two sides of the ridge body upwards and put the mulching films on the tobacco plants before gathering the new soil towards the stem base, and wrap the tobacco plants integrally, so that the tobacco leaves of the tobacco seedlings are not pressed in the gathering process of the new soil towards the stem base of the tobacco plants, and the whole process is completed by only one person, thereby being suitable for a new hilling process, effectively reducing the labor cost and improving the hilling efficiency and quality of the tobacco seedlings.
