Problems solved by technology

[0004] However, this method will cause "injury" at the root-cutting site, and the liquid flowing out from the root-cutting place is rich in nutrients needed for crop growth. If the loss is too much, it will cause weak growth. The necrosis of the cut root causes crop yield reduction or even withering

Embodiment 1

[0028] This embodiment is a kind of crop electrocoagulation pruning knife, such as figure 1 , 2 shown. This embodiment includes: a disc-shaped cutterhead 2 installed on the rotating shaft 1, the outer edge of the cutterhead is provided with cutting teeth 201, and the cutterhead is composed of at least two fan-shaped disk blocks, and one of the disk blocks is A slit 202 is left between them, and electrodes 203 are arranged in pairs in the slit.

[0029] This example uses electrocoagulation, after cutting off the root system of the crops, the cut-off part is burned with electric high-voltage, so that the cut-off point of the root system is instantly heated and coagulated, preventing the loss of nutrients in the root system of the crops, thereby avoiding "injury" at the cut-off part , reduce or even eliminate the situation that crop growth is affected after root pruning, and effectively improve the benefit and effect of root pruning.

[0030] The main idea of ​​this embodiment...

Embodiment 2

[0037] This embodiment is an improvement of the first embodiment, and it is a refinement of the first embodiment on the fan-shaped disk block. The fan-shaped disc block described in this embodiment gradually thickens along the circumferential direction, such as figure 2 shown.

[0038] The effect of the gradual thickening of the fan-shaped disk block is that the cutterheads on both sides of the slit are thicker on one side and thinner on the other, according to the rotation direction of the cutterhead ( figure 1 , 2 , the direction of arrow B in 3), the thick side is in the front, and the thin side is in the back. When cutting off the root system and soil, the thicker part of the cutterhead will discharge the soil more, so that although the soil rebounds when the cutterhead behind enters, it will not get into the narrow gap.

Embodiment 3

[0040] This embodiment is an improvement of the above-mentioned embodiment, and is a refinement of the above-mentioned embodiment with regard to sector disk blocks. A groove 204 is provided at the end of the fan-shaped disk block in this embodiment, and the electrodes are arranged in the groove, such as image 3 shown.

[0041] The groove is provided, and the insulating glue is coated in the groove, which can make the insulating glue more stable and make the pasted electrodes very stable.

Abstract

The invention relates to a crop electrocoagulation root cutter and system. The system comprises the electrocoagulation root cutter which is installed on an electrocoagulation cutter rotary shaft and is in a disc shape, cutting teeth are arranged on the edge of the disc, the disc is composed of at least two sector-shaped disc blocks, narrow gaps are reserved between the disc blocks, and electrocoagulation electrodes are arranged in the narrow gaps in pairs. By means of the mode that the narrow gaps are formed in the disc-shaped root cutter and internally provided with the electrodes, an electric shock mode in the crop root cutting process is achieved, the situation that nutritional liquid flows out from the cutter after crop roots are cut off is prevented, bleeding is reduced as much as possible, the crops obtained after root cutting quickly restore original growth tendency, and crop yield reduction and withering which are caused by root cut portion necrosis are avoided; the root cutter system controls the position, depth and angle of root cutting by using a cutting position, cutting depth and cutting angle control mechanism, the root cutting position and strength are effectively known, the water resource utilization rate in the crop growth process is increased, and soil moisture contents and fertility of farmland are improved and kept.

Description

technical field [0001] The invention relates to an electrocoagulation root removal knife and system for crops, which is a water-saving and environment-friendly farmland management measure, and a device and system for improving crop yield and water use efficiency. Background technique [0002] In the world, the shortage of water resources has attracted people's attention day by day, and the efficient use of agricultural water resources has become the main problem of world agricultural research. Therefore, the goal of modern agricultural research is no longer satisfied with high yield, but should also focus on saving resources and improving water resource utilization efficiency. The environmental resource with the strongest competition among plant individuals is soil water, and the root system is the most important organ for water competition. Root growth and development are closely related to crop yield. Reasonable regulation of root growth can promote the coordinated develo...
