Description
Technical field
The present invention relates to a kind of for making the polyurethane material of farm's chicken manure scraper plate.
Background technique
Broiler breeding field uses stainless steel chicken manure scraper plate in the prior art, and this scraper plate is slab construction, when scraping excrement, nothing
Method is tightly bonded with conveyer belt, it may appear that scrapes excrement failure phenomenon, conveyer belt chicken manure is caused to deposit, influence chicken manure conveying, influence chicken
Environment is given up, and is often mingled with water in chicken manure transportational process, scraper plate skids and easily gets rusty, and causes to damage to conveyer belt, influences
Tape lifetime is conveyed, it is poor to scrape excrement effect.
Summary of the invention
In order to solve the problems, such as that chicken manure scraper plate can not be tightly bonded with conveyer belt in the prior art, the present invention provides a kind of use
In the polyurethane material of production farm's chicken manure scraper plate, scraper plate includes a support portion, and a wedge-shaped part, wedge-shaped part height, which is greater than, to be supported
Portion's height is formed with fin, and the angle angle that bevel edge and the support portion bottom edge of wedge-shaped part are formed is 20-40 °, and the bevel edge of wedge-shaped part hangs down
Directly in the top of support portion, the angle of fin is 50-70 °, and is fillet；Support portion and wedge-shaped part are integrally formed；Vane material
For polyurethane；What vane material was made from the following raw materials in parts by weight: isocyanates is added in polytetrahydrofuran diol PTMG
TDI makes in the performed polymer after synthesizing-NCO content 6.8%；Chain extender MOCA is added in performed polymer；PTMG, TDI mass ratio is
2.7:1；The mass ratio of performed polymer and MOCA are 100:19.7；The preparation method comprises the following steps: by PTMG in 100-120 DEG C, vacuum degree 5-
It is dehydrated 1-2 hours, water content < 0.05% under 10Torr, dewatered PTMG is cooled to 50-70 DEG C, system heats up naturally
After 30-40min, PTMG and TDI is mixed in mixing head at 75-85 DEG C, keeps the temperature 2-3 hours, deaeration under 5-10Torr vacuum degree
The speed of 10-40min, 0.5kg/min-15kg/min are poured into mold, and mold temperature control is at 100 DEG C, 60min after gel
Material after demoulding, is then put into curing cage by demoulding, and temperature controls 110~120 DEG C of 10~12h of vulcanization.
Preferably: polytetrahydrofuran diol PTMG molecular weight is 1000.
Preferably: isocyanates TDI is TDI-100.
Preferably: hardness is Shao A95 degree.
Compared to stainless steel scraper plate more in the prior art, hardness of the present invention reaches Shao's A95 degree, and hardness is high, and wearability is good,
Frictional force in water environment is good, corrosion-resistant, and material has certain flexibility, when with conveyer belt cooperating, will not damage conveying
Band, the service life is high, and it is good to scrape excrement effect.
Compare the prior art, and the present invention is in use, support portion is clipped between two rigid plates, wedge-shaped part connects with conveyer belt
Chicken manure on conveyer belt is scraped off conveyer belt using the wedge shape of wedge-shaped part by touching, and the chicken manure after scraping off passes through at the fillet of wedge-shaped part,
Fillet setting avoids chicken manure from depositing herein, and excrement work is scraped in realization.
Due to usually being prevented on chicken manure conveyer belt containing the gas in some dilute excrement and henhouse in order to which gas is discharged
Excrement leaks out, and support portion is closing on the seal groove that setting is parallel with fin at fin.
Preferably: the distance of fin to seal groove is the 1/6-1/4 of support portion top size.
Preferably: location hole being set in the middle part of support portion, support portion is clipped between two rigid plates, realizes the positioning of scraper plate
Installation.
The beneficial effects of the present invention are:
The angle setting fitting conveyer belt of wedge-shaped part, and realize and scrape excrement, polyurethane material frictional force is big, avoids in water environment
It is middle to skid and get rusty.
MOCA ratio is high in material, and NCO content is high, improves material hardness, and adjust out suitable gelation rate, takes into account
The hardness and processing performance of product.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Below by specific embodiment, the present invention is further explained:
A kind of farm's chicken manure scraper plate, including a support portion 1, a wedge-shaped part 2, wedge-shaped part height are greater than support portion height,
