Problems solved by technology

And there is no special removal machine for Iridaceae plants at home and abroad, mostly manual removal
This method of removing impurities is labor-intensive and inefficient
Professor Wang Decheng of China Agricultural University and others once proposed "a device for removing leaves and crushing roots of Ma Lian" (patent publication number CN101558756A). Too crushed, long soil remediation time

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 Shown, root cutting method of the present invention, adopts double-sided cutter, oblique direction, the mode of operation of successively different cross-section burying, and cutter random tool traction direction advances longitudinally.

[0033] The depth of the above-mentioned root cutting operation is 200mm, and the distance between the slits on both sides is determined according to the angle of entry into the soil. The relationship is d=2h·tanα, where d is the slit distance between the two cutters; α is the distance between the cutter plane and the vertical plane. The included angle is the angle of entry into the soil. The entry angle is preferably 19° to 45°. Usually, three angles of 19°, 30° and 45° are selected; h is the entry depth of the cutter.

[0034] In order to realize this method of cutting roots of Iridaceae plan...

Abstract

The invention discloses a method and device for removing grassland weeds-iridaceous plants. In the method, cutters on both sides are used for obliquely cutting roots in soil in turn from different cross sections. The device comprises a frame, wherein the frame is provided with a transverse positioning hydraulic cylinder and a sliding plate; two ends of the sliding plate are arranged on the frame through slide blocks; the transverse positioning hydraulic cylinder is connected with one slide block; a pair of positive bars is arranged in the center of the sliding plate; the left side and the right side of each positive bar are provided with a group of angle adjusting devices respectively; the two groups of angle adjusting devices are arranged front and back in a staggered way; each group of angle adjusting devices is connected with a working hydraulic cylinder respectively; the lower end of each working hydraulic cylinder is connected with a cutter saddle; a hydraulic motor is fixedly connected with the cutter saddle and is connected with a cutter head; 3-4 cutters are uniformly distributed in the circumferential direction of the cutter head; and a left group of cutters and a right group of cutters are obliquely and oppositely arranged in a V shape. A practicable scheme is provided for the removal of iridaceous plants, and the method is suitable for improving grasslands degraded by heavy weed growth, is accordant with the concept of agricultural sustainable development, and has an extensive application prospect.

Description

technical field [0001] The invention belongs to the technical field of weed removal, and in particular relates to a removal method and a special removal device for Iridaceae plants such as Malian. Background technique [0002] At present, most of the grasslands in China are in a degraded state, and the degradation of some grasslands is manifested in the obvious reduction of the number of grasses in the original dominant species, while the Iridaceae plants that most domestic animals do not like to eat, such as Malian, are proliferating in large numbers. Group species of pastures form intense competition, which affects grass production and economic benefits, and causes grassland degradation. Therefore, in order to improve the population structure of such degraded grasslands, it is necessary to remove the mixed Iridaceae weeds. And still do not have the special-purpose removing machine tool of Iridaceae plant both at home and abroad at present, mostly be manually removed. Thi...
