[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a machine for burning and disinfecting floors such as soil for greenhouse horticulture, sand in a sandbox of a park, etc. with a flame, and for drying compost. The present invention relates to a floor soil sterilizer suitable for sterilization of an easy floor soil.

[0002]

2. Description of the Related Art To burn and sanitize sand in a sandbox in a park or the like, all the sand is transported and deposited from a sandbox to a square next to the sandbox by a shovel loader, and the deposited sand is sterilized by a conveyor on floor soil. The sand is then sent to the machine, and the accumulated sand is sterilized by the floor soil sterilizer, and the sand that has been sterilized by the earth is returned to the original sandbox using a shovel loader. However, the capacity of this floor soil sterilizer is about 140 to 1200 kg / H as the processing capacity, and the capacity is small as compared with the sand amount in the sandbox. However, the bed soil sterilizer adopts such a configuration because the time taken for the sand to be sterilized and discharged after burning is short, and continuously processed sand is discharged.

[0003] As a conventional technique of such a floor soil sterilizer used for burning sand in a sandbox, there is, for example, Japanese Utility Model Laid-Open No. 62-193.
875, JP-A-59-130449, JP-A-59-146531, and JP-A-59-23949.
There is a device such as Japanese Patent Publication No. In these inventions, the tip of the inlet hopper is looked into the opening at the center of one end plate of the rotating drum, and the other end of the rotating drum is released to serve as an outlet for floor soil. A common feature is that a stirring member for stirring the soil is attached to the rotating drum, and the flame is radiated from the outlet side of the rotating drum to the inlet hopper side. According to the above-mentioned method of disinfecting the soil in the sand pit, the place where the sand is deposited around the sand pit is occupied for several days together with the location of other machines, and the use of the park is significantly restricted, and depending on the park, The above processing method cannot be performed because it takes up a lot of space.

Accordingly, the present applicant has filed Japanese Patent Application No. Hei 5-136802.
The invention of the method for cleaning the sandbox of No. was proposed. According to the invention of the prior application, there is provided a method for cleaning a sandbox surrounded by concrete bordered by a park or the like, using a clay sintering machine (same as a floor soil sterilizer), a sand conveyor, a flame radiator and a stock case (1). ) A stock case and earthenware are placed outside the sandpit, and the sand outlet of the sand conveyor is connected to the earthenware inlet. (2) First, scan the sand inlet of the sand conveyor for the place to be a stock yard, carry it to the earthenware, put it in the earthenware, bake the sand, sterilize it with high temperature, and discharge the sand after the earthen sterilization to the stock case. By doing so, the accumulated sand in the earthmoving machine and the stock case causes the concrete rim and the bottom of the sandbox at the place to be the stock yard to appear and becomes the stock yard. (3) While the soil is sterilized by the earth-moving machine, the concrete rim and the bottom of the sand yard from which the sand in the sand yard has been carried out are burned and sterilized with a flame radiator. (4) After the above-mentioned stock yard is burned and sterilized by a flame radiator, the sand that has been sterilized in the stock case and accumulated in the stock case is returned to the stock yard. (5) The sand yard is moved by sending the sand next to the stock yard to the earthmoving machine with a sand conveyor, and the concrete edge and the bottom of the sand pit of the newly moved stock yard are burned and sterilized with a flame radiator. (6) The untreated sand next to the moved stockyard is sent to the earthmoving machine, and the sand of the stockcase is sterilized by baking the sand in the stockcase while creating a new stockyard by putting the sand that has been sterilized by the clay into the stockcase. By repeating the return to the new stockyard, the entire sand in the sandbox and the concrete edges and bottom of the sandbox are flame-burned and sterilized. As a result, the sand in the stock case was returned to the stock yard repeatedly, so that all the sand in the sand pit was accumulated outside the sand pit, and the soil was sterilized and returned to the sand pit as in the past. This eliminates the need to occupy a large area of the park square.

[0005]

However, in the above-mentioned method for cleaning a sandbox, a floor soil sterilizer (soiler), a sand carrier, a stock case and a flame radiator are used. This floor soil sterilizer requires fuel and usually uses propane. To supply the propane gas, the propane gas cylinder is transported to a sandbox. Also, there is usually no commercial power supply in the park, so a generator is needed. The above equipment is transported by truck to the outside of the park sandbox where it is unloaded except for the propane gas cylinder and generator. It takes about one hour for unloading and disposition after unloading, and then the gas pipe between the propane gas cylinder and the floor soil sterilizer, and the generator and the floor soil sterilizer. Electrical wiring must be done. After the burning of the floor soil in the sandbox is completed, remove the wiring between the generator and the floor sterilizer as described above, and remove the piping between the propane gas cylinder and the floor sterilizer, and then remove the floor soil sterilizer, sand transporter, and stock. The case and the flamethrower must be loaded on the truck. For this reason, unloading, loading, and wiring and piping from equipment trucks take a great deal of time. For example, if the sand processing time is 4 hours, unloading, loading, and laying wiring piping from trucks of machinery, It takes about 3 hours for removal.

SUMMARY OF THE INVENTION An object of the present invention is to provide a self-propelled floor soil sterilizer which requires less equipment for loading and unloading from a truck and requires less wiring and piping.

[0007] When baking soil for greenhouse horticulture in a conventional floor soil sterilizer in which a flame is blown from the outlet side to the inlet side of the above-mentioned rotary drum, bacteria in the soil are sterilized, and the operation is a special problem. Does not occur. When baking the sand in the sandbox of the park with the above-mentioned bed soil sterilizer, there is no difference in the effect of burning and sterilizing the soil with the above-mentioned facility gardening soil. When the sand was baked with the above-mentioned bed soil sterilizer, the dust passed through the inside of the hopper and through the hopper, and the dust was blown out and accumulated in the area around the dust. Even if the gap between the opening of the drum end plate and the outlet of the hopper is made small, dust flows in the inside of the hopper and flows upward against the sand introduced into the hopper.

[0008] The dust is considered to be fine sand in the sand and ash of the baked organic matter. In soil for greenhouse horticulture, the generation of dust is low in soil containing moisture, and the soil has poor fluidity in the hopper, so that the input hopper is appropriately material-sealed, whereas sand is It is thought that the material could hardly be sealed by flowing down the hopper rapidly.

[0009] The fermented compost has a lot of moisture and sweats in the bag, so it is not suitable for packing. Therefore, the above machine is used for drying, but dust is generated as in the above.

It is an object of the present invention to provide a self-propelled floor soil sterilizer capable of reducing the amount of dust generated even when a material such as sand, which tends to emit dust, is burned.

The operation of the above configuration will be described. This equipment is transported by truck along with propane gas cylinder and generator, and wholesales this equipment on sandy floor soil W.
The rotary joint 55 is connected to a propane gas cylinder, a wiring 58 and a rubber hose 59.

Next, when a switch for energizing each electric motor is operated and turned on from the control box 41, an electric motor for driving a hydraulic pump (not shown) is driven.

The clevis type hydraulic cylinder 53 is extended, and the loading means 5 is rotated clockwise in FIG.
The side is located above the floor soil W.

When the operation is started, the reduction motor 46a for urging the loading means 5 rotates, and the driving wheel 43 rotates clockwise via the chain transmission device 46b.
The belt 45 and the bucket 44 move in the direction of the arrow shown in FIG. On the other hand, the bed soil sterilizing means 3 is energized. That is, when the deceleration motor 27 is energized, the chain wheel 28 rotates, and the chain wheel 26 rotates via the chain 29 to drive the drive shaft 14.
Rotates, so that the rotating body 8 rotates. In this state, the burner 12 is ignited. Here, when the clevis type hydraulic cylinder 53 is contracted, the loading means 5 rotates counterclockwise around the same center as the driving wheel 43, the wheel 42 descends, and enters the floor soil W. The floor soil W is scooped and moved in the direction of the arrow shown in the figure to move the drive wheel 4.
When going round 3 downward, the floor soil W is dropped into the inlet 1. Then, the self-propelled means 4 is biased forward, and the four-way switching valve 37
Rotates the hydraulic rotating motor 36 in the forward direction, rotates the driving sprocket wheel 32 via the axle 35, moves the rubber shoe 34, and the self-propelling means 4 carries the floor soil sterilizing means 3 and the loading means 5 Move forward and create a recess W2 in the floor soil W. The sand charged to the floor soil sterilizing means 3 is at room temperature, but the flame 1
Drops on 3 and is preheated. Further, it falls from the flame tube 13 onto the bottom of the trough 6 immediately below. The sand that has fallen on the bottom of the trough 6 is lifted by the stirring plate 15 and advances toward the discharge port 2 by the spirally arranged chain 16 to a position without the flame tube 13. While there is sand at the position of the flame tube 13, the sand is heated by the flame tube 13 heated by the strong flame. Since the flame tube 13 exists immediately below the charging port 1, the flame tube 13
Without it, the flame of the burner 12 is disturbed, preventing a favorable combustion condition from being hindered. The sand that has progressed to a position where there is no flame tube 13 is lifted by the stirring plate 15 along the inner peripheral wall of the trunk 6a of the trough 6, and the chain 1 is arranged in a spiral.
6, the lifted sand rotates at least 4 minutes from the position at the bottom of the lowermost trough 6, and the stirring plate 15 moves toward the center of the trunk 6 a of the trough 6. When tilted downward, it falls from above the stirring plate 15 toward the center of the rotating body 8. The falling sand is exposed to the flame of the burner 12. Thus, the sand that has proceeded to the outlet 2 has a high temperature, and various bacteria in the sand are sterilized, and the organic matter becomes ash,
It falls from the discharge port 2 onto the recess W2 of the floor soil W. When the front surface of the loading means 5 approaches the concrete edge W1, for example, a limit switch 61 is provided slightly in front of the front surface of the loading means 5; When moving forward, the limit switch 61 finally hits the concrete edge W1. In response to the signal of the limit switch 61 detecting the concrete edge W1, the clevis type hydraulic cylinder 53 is extended, the loading means 5 is rotated so as to raise the wheel 42, and the self-propelled means 4 is stopped. As a result, when the sand in the floor soil sterilizing means 3 is burned and discharged and the recess W2 is backfilled with the sterilized sand, the self-propelled means 4 is shifted laterally by the width of the bucket 44 of the loading means 5. Retreat, move forward again and repeat the work. Thereby, the floor soil W of the sandbox is almost entirely burned and sterilized.

When the self-propelled floor soil sterilizer of this embodiment is used, the sand in the sandbox is disinfected by the loading means while traveling by the self-propelled means without being fixed as in the conventional floor soil sterilizer. The sand which has been burned by the bed soil sterilizing means can be returned to the recess W2 of the sandbox where the sand has been removed by the loading means.
Preparation and transportation are only unloading, wiring, piping and loading of the self-propelled floor soil sterilizer from a truck, so that preparation and transportation require only a short time. In addition, as in the past, a floor soil sterilizer, a means for transporting sand such as a shovel loader,
Since there is not much equipment like a conveyor, a truck with a small bed is sufficient.

Second Embodiment FIG. 8 shows a second embodiment. In the previous embodiment, a crawler made of a rubber shoe was used as the self-propelled means 4, but in this embodiment, four wheels 62 of a tire type are directly provided on the pedestal 7. By making the diameter of the wheel 62 large and wide, it is possible to cope with the floor soil W in a sandbox. The parts other than the self-propelled means 4 are the same as in the previous embodiment.
