Description

Add the preparation method of hometown earth sterilizing pesticide device

Technical field

The present invention relates to the soil field, be specifically related to a kind of preparation method that adds hometown earth sterilizing pesticide device.

Background technology

Generally being used for potted plant soil does not need special sterilization and sterilization, as long as can reach the effect of sterilization and sterilization through sunlight exposure, but the soil that is used for cuttage and sowing is wanted strictness to carry out disinfection and sterilized; Because germ is invaded in the flowers and trees body from the wound of inserting fringe easily, cause plant to rot, influence survival rate; Concerning sowing, the harsh bud that goes out, resistance very a little less than; Microorganism often causes it mouldy, reduces bud ratio.

Because the growth of the protection ground plantation time limit and the ubiquity of continuous cropping phenomenon; Cause soil serious deterioration to occur, many destructive diseases occur in a large number, and the generation of root knot nematode disease is in rising trend in recent years; Attached most importance to by harm with melon, tomato and celery; Diseased plant often reaches 30%～60%, the underproduction 20%～40%, and indivedual vegetables underproduction reach more than 80%.

Soil sterilization killing method commonly used has high-temperature sterilization, boiling sterilization and three kinds of methods of medicament sterilization; These conventional sterilization operation periods are long, consuming cost is high, yield poorly and labour intensity big, can not adapt to fast and the commercial operations demand of producing in batches.

Chinese patent Granted publication CN 201595115 U, on October 06 2010 Granted publication day, name is called " high-temperature sterilization desinsection baking oven ", discloses a kind of high-temperature sterilization desinsection baking oven, comprises soil hoisting equipment, soil discharger and soil apparatus for baking; Be provided with the soil hoisting equipment that soil is delivered into cabinets cavity through casing; The casing rear portion is provided with the soil discharger that is communicated with cabinets cavity; Casing is provided with the soil apparatus for baking that is used to toast soil in the soil discharger, utilizes the method for physics high temperature control, is applied in the agricultural production; Alternative agricultural chemicals carries out the control of damage by disease and insect and various germs; Not only effectively raise the control efficiency of damage by disease and insect and various germs, and prevent that agricultural chemicals from using back a large amount of residual and volatilizations to the healthy harm of soil, environment and human body, reaches and improve the soil, protect environment; Improve output and the quality of China crops comprehensively, guarantee the sustainable development of agricultural.

The weak point of above-mentioned patent is: the flame of " soil apparatus for baking " reverberatory furnace directly contacts with soil; Can not keep soil is toasted uniformly; And high-temperature baking is easy to destroy the granular structure of soil, and can cause soil compaction, influences growth and development of plant.

Summary of the invention

The objective of the invention is to overcome weak point in the prior art, a kind of preparation method that adds hometown earth sterilizing pesticide device is provided.

Adding hometown earth sterilizing pesticide device is a Horizontal Cylindrical Tank, is made up of cylindrical conduit, flange, feed hopper, sterilizing pesticide chamber, spiral conveying blade, central shaft, sealing plate, sealing ring, discharge nozzle, blast pipe, thermocouple, bearing block, shaft coupling and buncher.

The present invention is achieved through following technical proposals:

Right sealing plate of welding on the cylindrical conduit right side, the hole of a circle is opened at the center of right sealing plate, is used for the mounting center axle, places a right sealing ring between right sealing plate and the central shaft.

Central shaft is a hollow steel pipe, and spiral conveying blade is welded on the periphery of steel pipe, and the direction of rotation of advancing of spiral conveying blade is for clockwise; Central shaft after will welding is earlier put into cylindrical conduit, from the circular hole of right sealing plate, passes through, and right thermocouple is installed in the middle and upper part of right sealing plate; The dial plate of right thermocouple is on the right side of right sealing plate; The right bearing seat is installed in the right inner of central shaft, and shaft coupling is installed in the right top of central shaft, and central shaft links through shaft coupling and buncher.

At flange of cylindrical conduit left side welding, left sealing plate connects with flange with bolt, and left thermocouple is installed in the middle and upper part of left sealing plate; The dial plate of left side thermocouple is in the left side of left sealing plate; The hole that a circle is opened at the center of left side sealing plate is used for the mounting center axle, places a left sealing ring between left sealing plate and the central shaft; In the cylindrical conduit is the sterilizing pesticide chamber, and left shaft holder is installed in the left end of central shaft.

Be installed in the pot arch that is complementary with it adding hometown earth sterilizing pesticide device; Start buncher after lighting the fuel of pot arch; Central shaft in the cylindrical conduit begins to rotate, with as yet not the soil before the sterilizing pesticide to add sterilizing pesticide from feed hopper indoor, the flame in the pot arch carries out outer heating to cylindrical conduit; Its heat through cylindrical conduit indirect be transferred to the indoor soil of sterilizing pesticide; After the indoor temperature of sterilizing pesticide surpassed 60 degrees centigrade, germ and nematode in the soil will be killed successively, reach the effect of sterilizing pesticide; Soil behind the sterilizing pesticide flows out from discharge nozzle, and the steam in the sterilizing pesticide process in the soil is discharged from blast pipe.

Left side sealing plate connects with flange with bolt, and the central shaft and the spiral conveying blade that help externally heating in the soil sterilization insect-killing device are dismantled maintenance and installation.

About two thermocouples be used for the actual temperature of soil sterilization desinsection process in the measurement mechanism, in order to selecting for use the best temperature of heating that germ in the soil and nematode are killed, and can protect the granular structure of soil not to be damaged.

Add hometown earth sterilizing pesticide device and adopt external heating mode that soil is carried out sterilizing pesticide, add thermal-flame and directly do not contact, help keeping metastable temperature in the soil with soil; Improve the effect of sterilizing pesticide, reduce the loss of soil effective ingredient, production cost is low; Efficient is high, can continuity produce, and is easy to use; Save time and increase economic benefit of enterprises, help commercialization and apply.

Through after adding hometown earth sterilizing pesticide device sterilizing pesticide; Can the seed of the germ in the soil, nematode and weeds be killed successively; Be applicable to cuttage and the sowing of flowers, nursery stock, vegetables; Improve the bud ratio of seed, reduce the germination rate of weeds, guarantee that the normal growth of flowers, nursery stock and vegetables is grown.

Use adds hometown earth sterilizing pesticide device soil is carried out sterilizing pesticide, need not use agricultural chemicals, just can reach the effect of sterilizing pesticide, and it is not contaminated to help preserving the ecological environment.

Add hometown earth sterilizing pesticide device and be applicable to the sterilizing pesticide and the oven dry of various soil.
