Compacting, preferably covers mulch.
Working principle: first by connector 3 and power car (i.e. traction device, can for farm tractor or other
Pulling equipment) it is attached, the present invention is then adjusted to by suitable angle by the hydraulic device on power car, makes the present invention
Face alley, guarantee overlay film when direction it is parallel, the film roll 13 in film roll placing box 12 is installed at this time, by mulch
One end pull out and be pressed in the lower surface of mulch pressure roller 10, and the pull-out end of mulch is lived with earth mulch, at the uniform velocity starts power car, keep
Speed per hour, prevents from breaking mulch at 3-5 kilometers, at this time as the movement of power car starts that the present invention is driven to move
Overlay film, mulch pressure roller 10 compress mulch, and soil is covered on mulch two sides, second level earthing by the level-one covering device 9 of two sides
Device 7 enters second level earthing dress at 9 rear of level-one covering device, by the soil that level-one covering device 9 is covered on mulch two sides
Set 7 into native case 7.4 because into native case 7.4 be equipped with it is tubaeform into Tu Kou so that it is convenient to soil into defeated native case
In 7.1, driving motor 6 is opened, drives two driven pulleies 7.6 to be revolved simultaneously by the belt on drive pulley 16
Turn, driven pulley 7.6 drives corresponding spiral conveyor rod 7.2 to be rotated by connecting shaft 7.5, in this way will be into native case 7.4
Interior soil is transported in defeated native case 7.1, then is discharged on mulch by the pipe 7.3 that is unearthed, in this way since level-one covering device 9 is set
It sets in the position for not touching mulch, ensure that mulch dislocation occurs and the situations such as digs, avoid and cover again, and the pipe 7.3 that is unearthed
The soil of discharge ensure that the firm of mulch, so that not needing to ensure that work by being manually compacted with random device later
Efficiency saves time and resource.
The present invention is provided with alley compaction apparatus 11 in front of mulch pressure roller 10, when carrying out overlay film, it is first determined alley
Width, then the present invention is lifted by the hydraulic device on power car, then rotate two handles 11.8, in this way drive in
Screw shell 11.7 is rotated, because being provided with annular fixture block 11.9 and annular groove 11.10, such inner thread sleeve 11.7
When being moved on threaded rod 11.4, it also will drive two sliding block sleeves 11.6 and moved, thus have adjusted two branch
The distance between strut 11.11 increases practicability of the invention to adapt to the alley of different in width, then will be of the invention
Suitable angles and positions are placed on, because being provided with spring 11.14 in sleeve 11.15, in this way with the present invention and ground
Contact, spring 11.14 is in confined state, and the elastic force of spring 11.14 acts on and support rod 11.11 and mounting shell simultaneously
11.16, further ensure that soil can be compacted by compression roll 11.18 in this way, because compression roll 11.18 is rugby
Shape, in this way after entering soil, side wall can be close to alley side, soil is carried out under the action of the elastic force of spring 11.14
Compacting, and vertical bar 11.19 and cleaning shoe 11.20 are provided in mounting shell 11.16, it will be attached to compression roll 11.18 in this way
On soil be removed, ensure that the normal use of compression roll 11.18, in this way with movement of the invention, two compression rolls
11.18 are compacted the soil of alley side, ensure that the integrity degree of covering with ground sheeting, are not in the situation of ventilative gas leakage,
Or occur being overlapped or be bent, it avoids and re-starts covering, save the working time.
