Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sugarcane harvesting equipment, and particularly relates to a root cutter for preventing and controlling disease transmission by using medicine in the process of sugarcane machine harvesting. BACKGROUND

[0002] Sugarcane is a crop in the tropics and subtropics, and has a long growth period and planting cycle, a complex growth environment, and is prone to accumulate a large number of pathogens and insect sources, resulting in a large occurrence of diseases and pests. At present, there are more than 60 diseases and more than 360 pests in sugarcane in China; the main diseases include smut, stalk rot, rust, ratoon stunting disease, mosaic virus disease, yellow leaf virus disease and nematode disease, and the main pests include sugarcane borer, cotton aphid, thrips, mealybug, sugarcane turtle and sugarcane root saw beetle.

[0003] Sugarcane smut, pineapple disease, stalk rot, ratoon stunting disease and mosaic disease are common and are the main diseases in sugarcane areas in Guangxi. The pathogen of ratoon stunting disease is a kind of bacteria, which is mainly spread and spread to healthy sugarcane through seedlings and tillage tools such as sugarcane knives, harvesters, seed cutting machines and the like, and has a strong transmission. The sugarcane juice of diseased sugarcane diluted to 10,000 times still has infectivity, and the sugarcane juice placed indoors for 13 days and the contaminated sugarcane knife placed for 7 days also have infectivity.

[0004] The current prevention and control methods for ratoon stunting disease mainly include: 1) hot water treatment, which can only be used for newly planted sugarcane and cannot be used for ratoon sugarcane, and healthy ratoon sugarcane is easily infected by the pathogenic bacteria carried by the sugarcane knife during the harvesting process; 2) establishing a disease-free new variety population and a disease-free nursery, which has a high cost.

[0005] Therefore, people have also made certain research on the phenomenon of sugarcane operation machinery spreading pathogenic bacteria, and have proposed some solutions. For example, Chinese Patent Application No. 201920514624.3 discloses a sugarcane seedling rapid cutting device with a disinfection device, which comprises a U-shaped support mechanism, a cutting and disinfection mechanism and a base; the U-shaped support mechanism and the cutting and disinfection mechanism are sequentially arranged on the base; the U-shaped support mechanism comprises a supporting seat arranged on the base and a U-shaped support fixedly arranged on the supporting seat; the cutting and disinfection mechanism comprises a cutting machine, a disinfection nozzle arranged on the cutting protection shell of the cutting machine and a disinfection liquid container; the disinfection nozzle is sequentially connected with the disinfection liquid container through a liquid guide pipe, a switch and a pump. The significant advantages of the utility model are that 1) the sugarcane seedlings can be quickly cut off when the sugarcane seedlings are cut off, and the cutting surface is flat; 2) the disinfection work of the cut sugarcane seedlings is realized at the same time as the sugarcane seedlings are cut off, so that the disinfection spraying operation in the later period is not needed, and the preparation time of the sugarcane seedlings is greatly shortened. However, the structure of the device is only suitable for the sugarcane seedling production link, and cannot be applied to the sugarcane harvester. SUMMARY

[0006] The root cutter for preventing and controlling disease infection by using medicine in the sugarcane harvesting process can effectively reduce the risk of healthy sugarcane roots being infected by pathogenic bacteria.

[0007] In order to achieve the above object, the technical scheme adopted by the present application is as follows:

[0008] The root cutter for preventing and controlling disease infection by using medicine in the sugarcane harvesting process can effectively reduce the risk of healthy sugarcane roots being infected by pathogenic bacteria.

[0009] In the present application, the root cutter body is assembled by the slip ring stator, the slip ring rotor, the root cutter transmission shaft, the cutter disc, the root cutter and the like. Specifically, the slip ring stator is installed on the slip ring rotor through a bearing, and a circlip is arranged on the upper bearing; the slip ring rotor is installed on the root cutter transmission shaft through a bearing; the bottom end of the root cutter transmission shaft is fixedly installed with the cutter disc, and the top end is installed with a speed reducer and a motor; and the root cutter is fixedly installed below the axial edge of the cutter disc.

[0010] In the present application, the root cutter body is assembled by the slip ring stator, the slip ring rotor, the root cutter transmission shaft, the cutter disc, the root cutter and the like. Specifically, the slip ring stator is installed on the slip ring rotor through a bearing, and a circlip is arranged on the upper bearing; the slip ring rotor is installed on the root cutter transmission shaft through a bearing; the bottom end of the root cutter transmission shaft is fixedly installed with the cutter disc, and the top end is installed with a speed reducer and a motor; and the root cutter is fixedly installed below the axial edge of the cutter disc.

[0011] As a further illustration of the present application, the root cutter is provided with an atomizing device at the outlet of the pesticide tank. The pesticide is atomized by the atomizing device and evenly sprayed on the harvested root cut, achieving disease control of the root cut and reducing the risk of infection.

[0012] As a further illustration of the present application, a plurality of sealing rings are arranged between the slip ring stator and the slip ring rotor, above and below the annular groove. The sealing rings can prevent the pesticide from leaking through the gap between the slip ring stator and the slip ring rotor when entering the annular groove; the plurality of sealing rings arranged above and below the annular groove can further enhance the sealing effect.

[0013] As a further illustration of the present application, the pesticide tank is also provided with a liquid level indicator. The liquid level indicator can preferably use a liquid level monitoring sensor to indicate the remaining amount of pesticide in the tank, facilitating timely replenishment of the pesticide by the operator.

[0014] The working process of the present application is as follows:

[0015] The root cutter of the present application is provided with an independent start-stop switch arranged in the cab. The pesticide tank is provided with a liquid level monitoring sensor, and the driver in the cab of the sugarcane harvester can obtain real-time liquid level information and replenish the pesticide in a timely manner. Before the start of harvesting by the sugarcane harvester, the device switch is started first. During the harvesting process, the control unit of the present application receives the root cutter speed signal (speed 0-800 r / min), the harvester operating speed signal (0-10 km / h), and the flowmeter (0-5 L / min) flow signal for independent control, and gives the optimal pump speed (speed 0-5000 r / min, pressure 0-2.5 MPa) and electric control proportional valve (opening 0-1) control parameters. During operation, the pesticide is pumped out of the tank by the pump, passes through the electric control proportional valve, the flowmeter, the slip ring stator pipeline, the slip ring stator internal passage (passage I), the annular groove, the slip ring rotor internal passage (passage II), the slip ring rotor pipeline, the cutter head, and the root cutter (passage III), while the pesticide is atomized by the atomizing device and finally sprayed on the harvested root cut without forming droplets, completing the timely disease control of the harvested sugarcane roots and reducing the risk of infection.

[0016] Advantages of the present application:

[0017] 1. The root cutter of the present application can disinfect the root cutter with pesticide in real time during the sugarcane harvesting process, reducing the risk of pathogen transmission.

[0018] 2. The root cutter of the present application can disinfect and preventively treat the harvested sugarcane root cut with pesticide in real time during operation, effectively reducing the risk of healthy root infection by pathogenic bacteria.

[0019] 3. The root cutter of the application has simple structure, scientific design, low cost and good effect of preventing and controlling sugarcane diseases. BRIEF DESCRIPTION OF DRAWINGS
