Description

The present invention mainly provides extremely efficient means for improving contaminated soil, and the object of the present invention is to solve the problem of improving contaminated soil by the present invention device centered on the conveyor device unique to the present invention.
By the apparatus of the present invention, contaminated soil, various soil improving materials (for example, various powders and granular chemicals / chemicals, lime, water-absorbing water retaining agent, water-passing agent, water-repellent agent, etc.), various improved soils (for example, pearlite, Kanuma soil, compost, etc.), two or more types of transported materials such as various fertilizers are continuously transported to a set amount as a homogeneous powder / granular transported material that is evenly stirred and mixed without any lumps or internal cavities・ It can be supplied, that is, various desired transported materials are charged to the set amount in the transfer flow controlled to the set amount, and evenly mixed without any lumps or internal cavities. -It is possible to make a mixed powder / granular transported product, and to solve the problem by continuously producing and supplying a homogeneous and stable mixture.

Furthermore, the present invention is a device for improving soil such as the above-mentioned agricultural land and contaminated ground, as well as chemicals, drugs, agricultural products, feed, industrial / building materials, and other various powders / particles. When it is necessary to continuously stir, mix, transport and supply to the set amount in the state, and it can be widely used as a device to perform their quantitative blending, quantitative filling, quantitative packaging, etc.

For example, two or more types of transported materials are uniformly stirred and mixed without any lumps or internal cavities, such as concrete manufacturing (cement, sand, gravel, etc.), various mixed fertilizers, various mixed feeds, etc. It can be used as an optimum device for continuously conveying and supplying a set amount as a uniform powder / granular material.

Conventionally, for example, when improving contaminated soil such as farmland and contaminated ground, set amount (volume, weight, etc.) of contaminated soil, various soil improvement materials, various improved soil, etc. are put into a mixer etc. for a set ratio, It is generally carried out by mixing and stirring a certain amount per time until the whole becomes homogeneous, and the method of repeating the work many times is common, but it takes a lot of time each time, There is a problem that mixing and stirring each time are not constant,

In addition, after contaminated soil that has been excavated in farmland, contaminated ground, etc. and transported by bucket conveyors, dumpers, etc., is screened to a powder or granular form that is less than the set size with a soil sorting device such as Trommel, the contaminated soil and various soils Improving materials, various kinds of improved soil, etc. must be put into a mixer, etc. for one-time amount, mixed and stirred, then transferred again from the mixer etc. to other transport means, so the work is divided and the efficiency is extremely poor There was a problem.

Therefore, the present invention takes a lot of time for each conventional process, and there is a problem that mixing and stirring each time are not constant, and the work is divided and the efficiency is extremely poor.

According to the present invention, one or more coil spring-like conveyors having hollow portions are arranged in parallel in a housing, and all or all of them are rotationally driven so as to freely adjust their rotational speed so as to continuously convey a set amount of conveyed objects. In the conveyor device provided in the above, the conveyor is driven and rotated, and various types of transported materials such as contaminated soil and soil conditioner are loaded and supplied to the conveyor from each loading / feeding port. A plurality of types of conveyed items, characterized in that each conveyed item is stirred and mixed to form a homogeneous mixture, and the mixed conveyed item is discharged from the discharge port of the conveyor device and transferred to the next step. This is solved by a device that uniformly agitates and mixes and continuously conveys and feeds to a set amount.

In the present invention, one or more coil spring-shaped conveyors having hollow portions are arranged in parallel in the housing, and all or all of the conveyors are individually driven to freely adjust the rotational speed to continuously convey a set amount of the conveyed product. Equipped with a conveyor device,

Equipped with a discharge port for discharging the mixed transported material that has been transported to the outside,

The conveyor of the conveyor device is rotationally driven, and various conveyed items such as contaminated soil and soil conditioner are charged and supplied to the conveyor from the respective loading / feeding ports. Agitated and mixed to form a homogeneous mixture, and the mixed and conveyed product is discharged from the discharge port of the conveyor device and transferred to the next process. -The problem is solved by a device that mixes and continuously conveys and supplies to a set amount.

The present invention mainly provides extremely efficient means for improving contaminated soil, and the object of the present invention is to solve the problem of improving contaminated soil by the present invention apparatus centered on a conveyor device unique to the present invention. Contaminated soil, and various soil improvement materials (for example, various chemicals and chemicals in powder and granular form, lime, water-absorbing water retention agent, water-permeable agent, water-dispersing agent, etc.), various improved soils (for example, perlite, Kanuma soil, compost) Etc.), two or more types of transported materials such as various fertilizers can be transported and supplied continuously to a set amount as homogeneous powder / granular transported materials that are evenly stirred and mixed without any lumps or internal cavities, In other words, in the transport flow controlled to the set amount, various desired transported objects are charged to the set amount and supplied to the uniform amount of homogeneous powder / granular particles that are uniformly stirred and mixed without any lumps or internal cavities. It can be used as a transported object, The boss was mixture may then be manufactured and supplied continuously, there is an excellent effect.

Further, the present invention is a device for improving soil such as the above-mentioned agricultural land and contaminated ground, as well as chemicals, drugs, agricultural products, feed, industrial / building materials, and other various powders / particles. When it is necessary to continuously stir, mix, convey and supply to a set amount in a state, and to perform their quantitative blending, quantitative filling, quantitative packaging, etc., there is a feature that can be widely used as an apparatus.

For example, two or more types of transported materials are uniformly stirred and mixed without any lumps or internal cavities, such as concrete manufacturing (cement, sand, gravel, etc.), various mixed fertilizers, various mixed feeds, etc. It can be used as an optimum device for continuously conveying and supplying a set amount as a uniform powder / granular material.

In the conveyor apparatus of the present invention, among the conveyed items supplied from the input / supply port, powdery, granular or small lump-like items pass between the coils of the conveyor and reach the hollow part 2 or the bottom surface of the housing. After the hook is caught on the coil, it turns into a powder, granular or small lump by rotating the conveyor, and also passes between the coils to reach the inside of the hollow part or the bottom of the housing, and the powder supplied from the hopper. The whole body can be efficiently transferred to the conveyor and transported.

Then, the stirring of the internal powder by the rotating coil and the hollow part, the vibration of the coil generated by the rotational driving force and the frictional resistance of the powder, and the expansion and contraction action synergistically compress the powder while effectively unraveling it. Therefore, it is possible to prevent the powder from solidifying, agglomerating, dumpling, or forming cavities due to compression, as in the past. In this state, there is an effect that it is possible to perform intermittent or continuous accurate supply and precise metering, blending, and the like made possible thereby.
