Abstract
The present invention relates to a device for covering soil, which is suitable for seedling stages of mulching film crops. The device comprises a wafer for cutting soil, a soil filter screen, a blade for shoveling soil and a soil receiving board for protecting seedlings. The device for covering soil can be appended behind a cultivator and can also be operated by a person when in use. Cut soil is sent to a roller filter screen by the wafer for cutting soil; filtered soil is sent onto the soil receiving board by the blade for shoveling soil; the soil slides to the root of a mulching film crop along with the gradient of the soil receiving board for protecting seedlings to play the role of protecting seedlings and films.
Description
The present invention relates to a kind of agricultural tillage parts, particularly a kind of covering device.
Existing covering device as the covering device of cotton dibbling machine, can only be used at seeding time, and weak point is to use in seedling stage.
The objective of the invention is, provide a kind of crops seedling stage that is not subjected to influence covering device simple in structure.
This device comprises cuts native disk, screen pack, cylinder, band soil blade and clay-accepting plate for protecting seedling, cut an end of the contiguous cylinder of native disk, screen pack is installed in a close end of cutting native disk of cylinder, the screen pack indent, roller bearings is equipped with in the screen pack center, from the oblique another side in one side near screen pack, is distributed in the inner surface of cylinder with native blade, clay-accepting plate for protecting seedling puts in the root that tiltedly points to seedling in the cylinder, cuts native disk cylinder and all links to each other with frame with clay-accepting plate for protecting seedling.
The course of work of device of the present invention is: by cutting native disk the soil of having cut is passed through the soil property screen pack, the fine earth after the soil block filtration, by with native blade the top of soil zone to cylinder, make soil utilize own wt to fall into and put on the interior clay-accepting plate for protecting seedling of tube, make soil send into soil along the gradient of clay-accepting plate for protecting seedling the root of film crop.
Below comprehensive accompanying drawing the present invention will be further described: accompanying drawing is the structural representation of embodiments of the invention, with reference to figure, it is by cutting native disk (1) soil of having cut to be delivered to contiguous cylinder (3) soil property screen pack (2) on one side, filter out large clod, make fine earth to enter in the cylinder, make be with native blade (5) soil zone to cylinder top, make soil utilize deadweight to fall on the clay-accepting plate for protecting seedling (4) that puts in the cylinder, make soil utilize the gradient of clay-accepting plate for protecting seedling to slip into the root of film crop.
Claims (1)
1, a kind of ground film crops seedling stage covering device; It is characterized in that, this device comprises cuts native disk, screen pack, cylinder, band soil blade and clay-accepting plate for protecting seedling, cuts an end of the contiguous cylinder of native disk, and screen pack is installed in a close end of cutting native disk of cylinder, the screen pack indent, roller bearings is equipped with in the screen pack center, with an end oblique other end of native blade from close screen pack, the inner surface of the cylinder that all distributes, clay-accepting plate for protecting seedling puts in the cylinder, tiltedly point to the root of seedling, cut native disk, cylinder all links to each other with frame with clay-accepting plate for protecting seedling.
